     DETAILED DESCRIPTION 
     A description will be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. The reference symbols which are the same or similar throughout the accompanying drawings represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present disclosure, rather than being interpreted as limitations to the present disclosure. 
     In the prior art, the background picture required by the monitor function is usually stored in an external storage device, and is called by a processing module from the external storage device when the background picture is needed. However, applicant found that when the displaying of the monitor system is controlled by the prior art, it is inevitable that there are technical problems such as extremely high system cost, a relatively complex system structure design, and a relatively low level of intelligence. 
     A monitor system and a method for controlling displaying thereof according to the embodiments of the present disclosure are described below with reference to the accompanying drawings. 
       FIGS.  1  to  7    are schematic structural diagrams of monitor systems according to the embodiments of the present disclosure. 
     It should be noted that as shown in  FIG.  1   , in the present disclosure, the monitor system  1000  includes a controlling module  100 , a processing module  200 , and a display  300 . 
     The controlling module  100  is connected to the processing module  200 , and is configured to send human-machine interaction interface information and background picture information to the processing module  200  via a same channel. Here, the human-machine interaction interface information and the background picture information are pre-stored in a storage region of the controlling module  100  per se. Upon powering up the monitor system  1000 , the controlling module  100  automatically sends the stored human-machine interaction interface information and background picture information to the processing module  200  via a same low voltage differential signaling (LVDS) bus channel. 
     It should be noted that the human-machine interaction interface information and the background picture information may be set according to an actual situation. The human-machine interaction interface information includes: first human-machine interaction interface information and second human-machine interaction interface information. For example, the first human-machine interaction interface information may be set as power-on information of the monitor system  1000 ; the second human-machine interaction interface information may be set as other information sent based on a user instruction; and the background picture information may be set as relevant grid information. For example, the first human-machine interaction interface information may be set as a boot screen of the monitor system  1000 , and the boot screen may include information such as a name, a trademark, and a version number of an operating system; the second human-machine interaction interface information may be set as an abnormal warning, displaying parameters, and other information; and the background picture information may be set as coordinate information. 
     It should be noted that, in the present disclosure, when the controlling module  100  attempts to send the human-machine interaction interface information and the background picture information to the processing module  200  via the same channel, a time-sharing mode can be used to send the information. 
     As a possible implementation, upon powering up the monitor system  1000 , the controlling module  100  can acquire the first human-machine interaction interface information stored in its own storage region, and then send the acquired first human-machine interaction interface information to the processing module  200 . 
     Further, upon sending the first human-machine interaction interface information to the processing module  200 , the controlling module  100  may acquire the background picture information stored in its own storage region, and send the acquired background picture information to the processing module  200 . The pre-stored background picture information may be set according to an actual situation. 
     Further, after the controlling module  100  sends the background picture information to the processing module  200 , a user may input an instruction for sending the second human-machine interaction interface information via voice or a remote-control panel. After the user inputs the instruction for sending the second human-machine interaction interface information, the controlling module  100  may automatically respond to the instruction to send the corresponding second human-machine interaction interface information to the processing module  200 . 
     It should be noted that when the controlling module  100  attempts to send the human-machine interaction interface information and the background picture information to the processing module  200  in the time-sharing mode, a sending sequence can also be adjusted according to an actual situation. Optionally, upon powering up, the controlling module  100  sends the background picture information to the processing module  200 . Further, upon completion of sending the background picture information, the controlling module  100  sends the first human-machine interface interaction information to the processing module  200 . Further, upon completion of sending the first human-machine interface interaction information, the controlling module  100  sends the second human-machine interface interaction information to the processing module  200 . 
     It should be noted that, in the present disclosure, when the controlling module  100  attempts to send the human-machine interface interaction information and the background picture information to the processing module  200  via the same channel, the time-sharing mode is preferably adopted for sending. However, compared with the prior art, immediately sending the background picture information upon completion of sending the first human-machine interface interaction information cannot reduce the efficiency. 
     The processing module  200  is a processing core, is configured to receive the human-machine interaction interface information and the background picture information via one channel which are sent by the controlling module  100  and process the received human-machine interaction interface information and background picture information, and is further configured to receive video image information via another channel and process the received video image information. 
     Optionally, upon receiving the human-machine interaction interface information and background picture information, the processing module  200  performs synchronization processing on the received human-machine interaction interface information and background picture information, and stores the synchronized human-machine interaction interface information and background picture information in the storage region matched with the processing module  200 , respectively. 
     Optionally, upon receiving the video image information, the processing module  200  acquires a video image analysis result by analyzing the received video image information. Further, the received video image information and the acquired video image analysis result are performed synchronization processing, and the synchronized video image information and video image analysis result are stored in the storage region matched with the processing module  200 , respectively. Here, information contained in the video image analysis result may be set according to an actual situation. For example, it may be set that the video image analysis result contains histogram information, oscillogram information, vector graph information, and the like. 
     It should be noted that in order to ensure the definition of the displayed target image information, the video image information is high-definition image information with a resolution of 8 K. 
     It should be noted that, since a signal of the controlling module  100  and a signal of a sending module for video image information are different source signals, as mentioned above, the processing module  200  needs to perform frame synchronization processing on the information sent by the controlling module  100  and the information sent by the sending module for the video image information, so as to acquire relevant information after the synchronization processing. 
     Therefore, the synchronized human-machine interaction interface information, the synchronized background picture information, the synchronized video image information, and the synchronized video image analysis result are stored in the storage region of the processing module  200 , respectively. Further, the processing module  200  extracts the synchronized human-machine interaction interface information, the synchronized background picture information, the synchronized video image information, and the synchronized video image analysis result from the storage region, and performs superimposition processing on the above synchronized human-machine interaction interface information, synchronized background picture information, synchronized video image information, and synchronized video image analysis result to acquire target image information after the superimposition processing. 
     The processing module  200  is further configured to send the acquired target image information to the display  300 . 
     It should be noted that when the human-machine interaction interface information and the background picture information are transmitted between the controlling module  100  and the processing module  200 , a virtual connection can be established via a handshake mechanism, to ensure the synchronization of information sending and receiving, and the reliability of information transmission. 
     As a possible implementation, upon powering up the monitor system  1000 , the controlling module  100  sends the first human-machine interaction interface information to the processing module  200 ; and the processing module  200  receives and synchronizes the first human-machine interaction interface information, and then stores the synchronized first human-machine interaction interface information. 
     Further, upon completion of storing the first human-machine interaction interface information, that is, after no first human-machine interaction interface information is displayed, the processing module  200  feeds confirmation information back to the controlling module  100 ; upon receiving the confirmation information, the controlling module  100  sends the background picture information to the processing module  200  via the same channel; and the processing module  200  receives and synchronizes the background picture information, and then stores the synchronized background picture information. 
     Further, upon completion of storing the background picture information, the processing module  200  feeds confirmation information back to the controlling module  100 . Upon receiving the confirmation information, the controlling module  100  sends the second human-machine interaction interface information to the processing module  200  via the same channel. The processing module  200  receives and synchronizes the second human-machine interaction interface information, and then stores the synchronized second human-machine interaction interface information. 
     A display  300  is connected to the processing module  200 , and is configured to receive the target image information output by the processing module  200 , so as to display the acquired target image information. Here, the display  300  may be selected according to an actual situation. For example, in order to enable the monitor system  1000  to display the target image information more clearly and improve the efficiency of the method for controlling the displaying of the monitor system, an 8 K TV with a resolution of 8 K may be preferably selected. 
     In some embodiments, as shown in  FIG.  2   , the processing module  200  further includes: a first receiving unit  201 , a first writing controller  202 , a second writing controller  203 , a second receiving unit  204 , a video image analyzing unit  205 , a third writing controller  206 , and a first memory  207 .

     The first writing controller  202  and the second writing controller  203  are both connected to the first receiving unit  201 , and are configured to write the received human-machine interaction interface information and background picture information into the first memory  207 , respectively. Here, the first writing controller  202  and the second writing controller  203  communicate with the first memory  207  via an advanced extensible interface (AXI) bus, so as to realize transmission of the human-machine interaction interface information and the background picture information between the writing controller and the first memory  207 .

Further, the video image analyzing unit  205  is further configured to send the video image analysis result to the third writing controller  206 . 
     The third writing controller  206  writes the received video image analysis result into the first memory  207 . Here, the third writing controller  206  communicates with the first memory  207  via the AXI bus, so as to realize transmission of the video image analysis result between the third writing controller  206  and the first memory  207 . 
     The first memory  207  is configured to perform synchronization processing on the video image analysis result, the human-machine interaction interface information, and the background picture information, and store the synchronized video image analysis result, the synchronized human-machine interaction interface information, and the synchronized background picture information which are acquired after the synchronization processing. Here, the first memory  207  may be selected according to an actual situation. For example, in order to reduce the energy consumption of the monitor system  1000  and improve the information transmission efficiency, a double-data-rate 3 synchronous dynamic RAM (DDR3) better in power saving and higher in transmission efficiency may preferably be selected. 
     In some embodiments, as shown in  FIG.  3   , the processing module  200  further includes a fourth writing controller  208  and a second memory  209 . 
     The fourth writing controller  208  writes the received video image information into the second memory  209 . Here, the fourth writing controller  208  communicates with the second memory  209  via the AXI bus, so as to realize transmission of the video image information between the fourth writing controller  208  and the second memory  209 . 
     The second memory  209  is configured to perform synchronization processing on the video image information and store synchronized video image information acquired after the synchronization processing. Here, the second memory  209  may be selected according to an actual situation. For example, the DDR3 is preferred.

Further, the first fourth reading control to the fourth reading controller send the read synchronized video image analysis result, synchronized human-machine interaction interface information, synchronized background picture information, and synchronized video image information to the image superimposing unit  214 . 
     The image superimposing unit  214  is connected to the sending unit  215 , and is configured to acquire the target image information by performing synchronization processing on the synchronized video image analysis result, the synchronized human-machine interaction interface information, the synchronized background picture information, and the synchronized video image information which are read by the reading controllers. 
     The image superimposing unit  214  is further configured to output the target image information acquired after the synchronization processing to the sending unit  215 . 
     It should be noted that, in the present disclosure, there is no limitation on the way of superimposing information, and it may be selected according to an actual situation.

     In some embodiments, as shown in  FIG.  5   , the processing module  200  further includes a third receiving unit  216  and a command detecting unit  217 . 
     It should be noted that since the controlling module can send the human-machine interface interaction information and the background picture information via the same channel in the time-sharing mode, in order to enable different writing controllers to match different pieces of received information, the controlling module  100  sends different commands to the processing module while sending the human-machine interface interaction information and the background picture information. 
     Optionally, the controlling module  100  sends a first command to the processing module  200  while sending the human-machine interaction interface information to the processing module  200 ; and the controlling module  100  sends a second command to the processing module  200  while sending the background picture information to the processing module  200 .

     A third receiving unit  216  communicates with the controlling module  100  via an inter-integrated circuit (IIC), and is configured to receive the first command and the second command sent by the controlling module  100 . 
     The command detecting unit  217  is connected to the third receiving unit  216 , and is configured to recognize a received command and control a matched writing controller to work based on a recognition result. In the case that the received command is recognized as the first command, the first writing controller  202  may be controlled to start working; and in the case that the received command is recognized as the second command, the second writing controller  203  may be controlled to start working. 
     It should be noted that, as shown in  FIG.  6   , in the present disclosure, the controlling module  100  is preferably a system on chip (SOC), and the processing module  200  is preferably a field programmable gate array (FPGA), such that the monitor system provided by the present disclosure can store the background picture information in the SOC, acquire the target image information by processing relevant information through two boards of the SOC and the FPGA, and then, display the target image information on the display, realizing the control over the displaying of the monitor system. Here, a loading sequence of the human-machine interaction interface information and the background picture information is as shown in  FIG.  7   . 
     As a possible implementation, upon powering up the monitor system  1000 , the SOC sends the stored first human-machine interaction interface information to the first receiving unit  201 , and simultaneously sends a first command to the command detecting unit  217 . Upon receiving the first command, the command detecting unit  217  controls the first writing controller  202  to work to write the first human-machine interaction interface information received by the first receiving unit  217  into the first memory  207 . Upon completion of storing the first human-machine interaction interface information, the SOC sends the stored background picture information to the first receiving unit  201  via the same channel, and simultaneously sends a second command to the command detecting unit  217 . Upon receiving the second command, the command detecting unit  217  controls the second writing controller  203  to work to write the background picture information received by the first receiving unit into the first memory  207 . Upon completion of storing the background picture information, the SOC sends the stored second human-machine interaction interface information to the first receiving unit  201  via the same channel, and simultaneously sends the first command to the command detecting unit  217 . Upon receiving the first command, the command detecting unit  217  controls the first writing controller  202  to work to write the second human-machine interaction interface information received by the first receiving unit into the first memory  207 . 
     Further, the second receiving unit  204  receives video image information and sends the received video image information to the video image analyzing unit  205  to analyze the video image information. The video image analyzing unit  205  sends a video image information analysis result to the third writing controller  206  to write the video image analysis result into the first memory  207  via the third writing controller  206 . Meanwhile, the second receiving unit  204  sends the received video image information to the fourth writing controller  208 , such that the fourth writing controller  208  can write the video image information into the second memory  209 . 
     Further, the first reading controller  210  to the third reading controller  212  respectively read the synchronized human-machine interaction interface information, the synchronized background picture information, and the synchronized video image analysis result from the first memory  207 , and send the read synchronized human-machine interaction interface information, synchronized background picture information, and synchronized video image analysis result to the image superimposing unit  214 . The fourth reading controller  213  reads the synchronized video image information from the second memory  209  and sends the read synchronized video image information to the image superimposing unit  214 . 
     Further, the image superimposing unit  214  acquires target image information by performing superimposition processing on the received synchronized human-machine interaction interface information, synchronized background picture information, synchronized video image analysis result, and synchronized video image information, and sends the target image information to the sending unit  215 . The sending unit  215  sends the received target image information to the display  300 . 
     In summary, in the monitor system provided by the present disclosure, the background picture information is stored in the controlling module, such that after the controlling module sends the human-machine interaction interface information and the background picture information to the processing module via the same channel, the processing module can perform processing on the received video image information, human-machine interaction interface information, and background picture information, and send the target image information acquired after the processing to the display, thereby displaying the target image information on the display, and realizing control over the displaying of the monitor system, without a need to additionally provide an external device to store the background picture information. Thus, technical problems of high cost, high structure design difficulty, low control accuracy, and a low level of intelligence in a process of controlling the displaying of the monitor system in the prior art are avoided. 
     It should be noted that in the method for controlling the displaying of the monitor system provided by the present disclosure, based on characteristics of single writing and repeated reading of the background picture information, the background picture information is pre-stored in the controlling module, such that after the initial operation of the monitor system upon powering up, the controlling module can send the human-machine interaction interface information and the background picture information stored in its own the storage region to the processing module via the same channel; the processing module performs frame synchronizing on the received human-machine interaction interface information and background picture information as well as the video image information sent by another different source signal, and acquires the target image information by superimposing the synchronized relevant information; and finally, the target image information is displayed on the display. 
       FIG.  8    is a schematic flowchart of a method for controlling displaying of a monitor system according to an embodiment of the present disclosure. As shown in  FIG.  8   , the method particularly includes the following steps. 
     In S 101 , human-machine interaction interface information and background picture information are sent by a controlling module to a processing module via a same channel. 
     Optionally, upon powering up the monitor system, the controlling module sends the human-machine interaction interface information and the background picture information stored in its own storage region to a first receiving unit in the processing module via the same channel. Here, the human-machine interaction interface information includes first human-machine interaction interface information and second human-machine interaction interface information; and the first human-machine interaction interface information, the second human-machine interaction interface information, and the background picture information may be set according to an actual situation. For example, the first human-machine interaction interface information may be set as a boot screen; the second human-machine interaction interface information may be set as an abnormal warning; and the background picture information may be set as coordinate information. 
     In S 102 , video image information is received by the processing module, the video image information, the human-machine interaction interface information, and the background picture information are performed processing by the processing module, and target image information acquired after the processing is output by the processing module to a display. 
     As a possible implementation, as shown in  FIG.  9   , S 102  particularly includes the following steps. 
     In S 1021 , the video image information is received, and a video image analysis result is acquired by analyzing the video image information. 
     Optionally, the second receiving unit receives the video image information and sends the received video image information to a video image analyzing unit. Further, the video image analyzing unit acquires the video image analysis result by analyzing the received video image information, and sends the video image analysis result to a third writing controller. Here, the video image information is high-definition image information with a resolution of 8 K. 
     It should be noted that information contained in the video image analysis result may be set according to an actual situation. For example, it may be set that the video image analysis result contains histogram information, oscillogram information, vector graph information, and the like. 
     In S 1022 , the video image analysis result, the human-machine interaction interface information, and the background picture information are performed synchronization processing, and a synchronized video image analysis result, synchronized human-machine interaction interface information, and synchronized background picture information which are acquired after the synchronization processing are stored. 
     Optionally, a first writing controller, a second writing controller, and the third writing controller write the received human-machine interface interaction information, background picture information, and video image analysis result into a first memory, respectively. Here, the human-machine interaction interface information includes first human-machine interaction interface information and second human-machine interaction interface information. 
     In S 1023 , video image information is performed synchronization processing, and synchronized video image information acquired after the synchronization processing is stored. 
     Optionally, upon receiving the video image information, the second receiving unit sends the video image information to a fourth writing controller, such that the fourth writing controller writes the received video image information into a second memory. 
     In S 1024 , target image information is acquired by performing superimposition processing on the synchronized video image analysis result, the synchronized human-machine interaction interface information, the synchronized background picture information, and the synchronized video image information. 
     Optionally, a first reading controller, the second reading controller, and a third reading controller read the synchronized human-machine interaction interface information, the synchronized background picture information, and the synchronized video image analysis result from the first memory, respectively, and send the read synchronized human-machine interaction interface information, synchronized background picture information and synchronized video image analysis result to the image superimposing unit. The fourth reading controller reads the synchronized video image information from the second memory, and sends the read synchronized video image information to the image superimposing unit. 
     Further, the image superimposing unit performs superimposition processing on the received synchronized human-machine interaction interface information, synchronized background picture information, synchronized video image analysis result, and synchronized video image information, and thus, acquires target image information acquired after the superimposition processing. 
     For example, after the synchronized human-machine interaction interface information, the synchronized background picture information, the synchronized video image information, and the synchronized video image analysis result are acquired, the target image information acquired after the superimposition processing can be calculated according to an equation of Imagep=k1*Image1+k2*Image2+k3*Image3+k4*Image4. Here, Imagep represents the target image information after the superimposition processing; Image1 represents the synchronized human-machine interaction interface information; Image2 represents the synchronized background picture information; Image3 represents the synchronized video image information; Image4 represents the synchronized video image analysis result; and K1 to K4 represent parameters of the synchronized human-machine interaction interface information, the synchronized background picture information, the synchronized video image information, and the synchronized video image analysis result, respectively, and may be any real number. Optionally, k1+k2+k3+k4=1. 
     In S 1025 , the target image information is output to a display. 
     Optionally, the image superimposing unit sends the target image information to the sending unit, and the sending unit sends the received target image information to the display. 
     In S 103 , the target image information is displayed by the display. 
     Optionally, the display displays the target image information upon receiving the target image information sent by the sending unit. 
     Therefore, in the method for controlling the displaying of the monitor system provided by the present disclosure, the background picture information is stored in the controlling module, such that after the controlling module sends the human-machine interaction interface information and the background picture information to the processing module via the same channel, the processing module can perform processing on the received video image information, human-machine interaction interface information, and background picture information, and send the target image information acquired after the processing to the display, thereby displaying the target image information on the display, and realizing control over the displaying of the monitor system, without a need to additionally provide an external device to store the background picture information. Thus, technical problems of high cost, high structure design difficulty, low control accuracy, and a low level of intelligence in a process of controlling the displaying of the monitor system in the prior art are avoided. 
     It should be noted that when the human-machine interaction interface information and the background picture information are transmitted between the controlling module and the processing module, a virtual connection can be established via a handshake mechanism, to ensure the synchronization of information sending and receiving, and the reliability of information transmission. 
     For example, upon powering up the monitor system, the controlling module sends a boot screen to the processing module; and the processing module receives and synchronizes the boot screen, and then stores the synchronized boot screen. Further, upon completion of storing the boot screen, that is, after no boot screen is displayed, the processing module feeds confirmation information back to the controlling module; upon receiving the confirmation information, the controlling module sends the background picture information to the processing module via the same channel; and the processing module receives and synchronizes the background picture information, and then stores the synchronized background picture information. Further, upon completion of storing the background picture information, the processing module feeds confirmation information back to the controlling module; and upon receiving the confirmation information, the controlling module sends second human-machine interaction information to the processing module via the same channel, and the processing module receives and synchronizes the second human-machine interaction information, and then stores the synchronized second human-machine interaction information. 
     Therefore, the method for controlling the displaying of the monitor system provided by the present disclosure can ensure the reliability of information transmission by establishing the handshake mechanism when the controlling module tries to send the human-machine interaction interface information and the background picture information to the processing module via the same channel, such that the control accuracy of the method for controlling the displaying of the monitor system provided by the present disclosure is improved.

     In S 203 , a displaying channel is entered, and whether no first human-machine interaction interface information is displayed is determined. 
     Optionally, in the case that it is recognized that no first human-machine interaction interface information is displayed, S 204  may be executed; and in the case that it is recognized that the first human-machine interaction interface information is still displayed, determining whether no first human-machine interaction interface information is displayed can be continued.
