For the purpose of simplicity and descriptiveness, the principles of the present invention are mainly described herein with reference to the exemplary embodiments of the present invention. However, those skilled in the art will easily understand that the same principles may be equivalently applied to all types of radio signal apparatuses and personal mobile terminals, systems using the radio signal apparatuses and personal mobile terminals, and/or methods correspondingly performed by the radio signal apparatuses and personal mobile terminals, in which these same principles can be implemented, and any change of this type does not depart from the actual spirit and scope of the present patent application.

Electrical, mechanical, logical, and structural changes can be made to these embodiments without departing from the spirit and scope of the present invention. In addition, the features of the present invention are disclosed with reference to only one of several implementations/embodiments. However, provided that a feature may be expected and/or beneficial for any given or recognizable function, this feature may be combined with one or more other features in other implementations/embodiments. Therefore, the following descriptions should not be considered to be limitative, and the scope of the present invention is defined by the appended claims and equivalents thereof.

<FIG> is a schematic diagram of a system according to an embodiment of the present invention, where a radio signal apparatus and a personal mobile terminal interacting with the radio signal apparatus in an embodiment of the present invention are provided. The system <NUM> shown in <FIG> may be a communications system for an elevator system, and is, for example, used as a part of the communications system for the elevator system. The system <NUM> may implement communication exchange between a radio signal apparatus <NUM> and a personal mobile terminal <NUM> in the embodiment of the present invention. In an embodiment, the radio signal apparatus <NUM> can establish a communication connection to an elevator controller of the elevator system by using, for example, a Remote Serial Link (RSL) processor. The radio signal apparatus <NUM> may send or broadcast a radio signal, and the personal mobile terminal <NUM> may receive the radio signal and may establish a wireless connection to the radio signal apparatus <NUM> according to a requirement, so as to implement communication exchange between the radio signal apparatus <NUM> and the personal mobile terminal <NUM>.

As shown in <FIG>, an identity (ID) <NUM> is configured for the radio signal apparatus <NUM>. The radio signal apparatus <NUM> may broadcast the identity <NUM>. The identity <NUM> includes a floor information bit. The floor information bit is used to indicate floor information of the radio signal apparatus <NUM>. Specifically, in a definition form of the identity <NUM> in an example shown in <FIG>, "xxx" in the identity <NUM> indicates an identifier bit, and may be, for example, a universally unique identifier (UUID). An identifier bit of the identity <NUM> of each radio signal apparatus <NUM> in the elevator system may be uniformly preallocated. For example, if the radio signal apparatus <NUM> is mounted in an elevator car, the identifier "xxx" may be set based on an identity of the elevator car. "yyy" in the identity <NUM> indicates a type of the radio signal apparatus <NUM>. For example, if the radio signal apparatus <NUM> is a BLE module, "yyy" may be set to "BLE". "n" in the identity <NUM> is a floor information bit at the end, and indicates the floor information of the radio signal apparatus <NUM>. For example, if n=<NUM>, it indicates that the radio signal apparatus <NUM> is on the <NUM>th floor.

At the same time when an antenna of the radio signal apparatus <NUM> broadcasts a radio signal, the identity <NUM> is broadcasted continuously or at predetermined time intervals. Correspondingly, the personal mobile terminal <NUM> in this embodiment of the present invention may continuously or intermittently scan for a radio signal, so as to acquire a current selectable radio signal for establishing a wireless connection. For example, if entering the coverage area of a radio signal broadcasted by the radio signal apparatus <NUM>, the personal mobile terminal <NUM> may automatically detect the radio signal.

Each personal mobile terminal <NUM> in the embodiment of the present invention can perform, without establishing a connection to the radio signal apparatus <NUM>, a scan to recognize the identity <NUM> broadcasted by the radio signal apparatus <NUM>, so that the personal mobile terminal <NUM> can acquire current floor information (for example, the "nth floor") of the personal mobile terminal <NUM> based on the floor information bit (for example, "n") in the recognized identity <NUM>. As such, the personal mobile terminal <NUM> applied to the communications system in the embodiment of the present invention may obtain the current floor information of the personal mobile terminal <NUM> without establishing a connection to the radio signal apparatus <NUM>.

Specifically, in an embodiment, a wireless communications unit (for example, a Bluetooth communications module) is configured in each personal mobile terminal <NUM>. The wireless communications unit scans for nearby radio signals, and performs scans to recognize an identity <NUM> in each radio signal. A corresponding component may be disposed in the wireless communications unit to acquire the floor information indicated by the floor information bit in the identity <NUM>, or may send the identity <NUM> to a corresponding component (for example, a processor) of the personal mobile terminal <NUM> to analyze the floor information bit in the identity <NUM> and acquire the floor information indicated by the floor information bit, so as to acquire the current floor information of the personal mobile terminal <NUM>.

Therefore, in the system <NUM> in the foregoing embodiments, each personal mobile terminal <NUM> may acquire current floor information of the personal mobile terminal <NUM> without establishing a connection to a corresponding radio signal apparatus <NUM>. In other words, a currently processed floor location can be automatically acquired as long as the personal mobile terminal <NUM> can detect or sense a radio signal. As such, it is possible that the personal mobile terminal <NUM> does not need to occupy the connection capacity at a moment or continuously. This is particularly significant if the radio signal apparatus <NUM> corresponds to a relatively large quantity of personal mobile terminals <NUM> (for example, when a quantity z of personal mobile terminals <NUM><NUM> to <NUM>z shown in <FIG> is very large). It is unnecessary for each personal mobile terminal <NUM> to establish a wireless connection to the radio signal apparatus <NUM>, so as to achieve fast response. Each personal mobile terminal <NUM> may rapidly acquire the floor information. Alternatively, this is particularly significant if the radio signal apparatus <NUM> needs to be connected to one or more personal mobile terminals <NUM> to implement other functions (for example, each personal mobile terminal <NUM> needs to establish a connection to the radio signal apparatus <NUM> to send a call request command and/or a destination-floor registration command from the personal mobile terminal <NUM>). As such, as the connection capacity is not occupied, the connection between the personal mobile terminal <NUM> and the radio signal apparatus <NUM> is not hindered, so that the implementation of the foregoing other functions is not hindered.

In an embodiment, the radio signal apparatus <NUM> is a Bluetooth module, and is specifically, for example, a BLE module that can broadcast a Bluetooth signal. Correspondingly, it is chosen that the wireless communications unit of the personal mobile terminal <NUM> is disposed as the Bluetooth communications module. The Bluetooth communications module and the Bluetooth module may perform Bluetooth interaction and communication based on a Bluetooth <NUM> protocol. The Bluetooth module may perform scans and establish connections, so as to sequentially establish a Bluetooth connection to each of a plurality of personal mobile terminals <NUM>. As such, each personal mobile terminal <NUM> can implement a corresponding function such as a call request function and/or a destination-floor registration function by using the Bluetooth module. The Bluetooth module has relatively limited connection capacity. Therefore, the system <NUM> in the foregoing embodiments has a more obvious effect if the radio signal apparatus <NUM> is a Bluetooth module.

<FIG> is a schematic diagram of a modular structure of a radio signal apparatus <NUM> according to an embodiment of the present invention. In the embodiment shown in <FIG>, the radio signal apparatus <NUM> is a Bluetooth module <NUM>, and has an identity setting unit <NUM>, a Bluetooth processor <NUM>, and an antenna <NUM>. The identity setting unit <NUM> may set an identity <NUM> of the radio signal apparatus <NUM>, and particularly, set a floor information bit of the identity <NUM>. In an embodiment, the floor information bit of the identity <NUM> is fixed (for example, when the radio signal apparatus <NUM> is fixedly mounted in a landing area), and the identity setting unit <NUM> sets the identity <NUM> that no longer changes. In another embodiment, the floor information bit of the identity <NUM> changes dynamically (for example, when the radio signal apparatus <NUM> is fixedly mounted in an elevator car), and the identity setting unit <NUM> can dynamically acquire current floor information of the radio signal apparatus <NUM> from an elevator system, and dynamically write the floor information into the floor information bit of the identity <NUM>.

In an embodiment, as shown in <FIG>, the identity setting unit <NUM> may establish a communication connection to an elevator controller of the elevator system by using, for example, an RSL processor <NUM>, so that the floor information of the radio signal apparatus <NUM> can be conveniently acquired.

It should be noted that a specific type of the radio signal apparatus <NUM> is not limited to a Bluetooth module in the foregoing embodiments. For example, the radio signal apparatus may further be another type of radio signal apparatus such as a Wifi module, or another radio signal apparatus similar to the Bluetooth module known to those skilled in the art. It will be understood that another radio signal apparatus that appears after the filing date of the present application and is similar to the Bluetooth module may also be alternatively applied to the present invention to implement the objectives and solutions of the present invention.

The present invention provides an elevator system to which the system <NUM> in the foregoing embodiments is applied.

In an embodiment of the elevator system, as shown in <FIG>, the radio signal apparatus <NUM>-<NUM> in the embodiment shown in <FIG> of the present invention is disposed in an elevator car <NUM> of the elevator system (for example, the radio signal apparatus <NUM>-<NUM> and a destination-floor registration control panel are integrally mounted). The radio signal apparatus <NUM>-<NUM> may be a BLE module and can broadcast a radio signal such as a Bluetooth signal to at least cover the internal area of the elevator car <NUM>. The radio signal apparatus <NUM>-<NUM> may establish a wireless connection (for example, a Bluetooth connection) to a personal mobile terminal <NUM> based on the radio signal broadcasted by the radio signal apparatus <NUM>-<NUM>, and receive, when the wireless connection is established, a destination-floor registration command sent from the personal mobile terminal <NUM>. As such, when approaching or entering the elevator car <NUM>, a passenger <NUM> carrying the personal mobile terminal <NUM> can register a destination floor in an operation-free manner. The passenger <NUM> does not need to manually register a destination floor on the destination-floor registration control panel in the elevator car <NUM>, or does not need to manually register a destination floor on the personal mobile terminal <NUM>.

In an embodiment of the elevator system, as shown in <FIG>, the radio signal apparatus <NUM>-<NUM> in the embodiment shown in <FIG> of the present invention is disposed in a landing area <NUM> of the elevator system. The radio signal apparatus <NUM>-<NUM> may be a BLE module (for example, the radio signal apparatus <NUM>-<NUM> and a call control panel are integrally mounted), and can broadcast a radio signal such as a Bluetooth signal to at least cover the landing area <NUM>. The radio signal apparatus <NUM>-<NUM> may establish a wireless connection (for example, a Bluetooth connection) to the personal mobile terminal <NUM> based on the Bluetooth signal broadcasted by the radio signal apparatus <NUM>-<NUM>, and receive, when the wireless connection is established, a call request command about a call direction (for example, upward or downward) sent from the personal mobile terminal <NUM>. As such, when approaching or entering the landing area <NUM>, the passenger <NUM> carrying the personal mobile terminal <NUM> can complete a call request in an operation-free manner. The passenger <NUM> does not need to manually register a call operation on the call control panel in the landing area <NUM>, or does not need to manually register a call operation on the personal mobile terminal <NUM>.

In an alternative embodiment, the radio signal apparatus <NUM>-<NUM> shown in <FIG> may also receive a call request command about a call direction and a destination floor sent from the personal mobile terminal <NUM>. As such, the registration of a destination floor can be completed without depending on the radio signal apparatus <NUM>-<NUM> of the elevator car <NUM>.

In the elevator system <NUM> in an embodiment of the present invention, the connection capacity provided by the radio signal apparatus <NUM> may be used as much as possible to establish a wireless connection during the foregoing automatic elevator service request, so that it can be ensured that the function of the foregoing automatic elevator service request is completed in a timely and successful manner and passengers have desirable call experience.

With reference to <FIG> and <FIG>, an example of the application of the system <NUM> in the embodiment of the present invention is described.

As shown in <FIG>, the radio signal apparatus <NUM>-<NUM> (for example, a BLE module) is mounted in the elevator car <NUM>, and broadcasts a Bluetooth signal or the like. A passenger <NUM> who enters the elevator car <NUM> needs to establish a Bluetooth connection to the radio signal apparatus <NUM>-<NUM> by using a personal mobile terminal <NUM> carried by the passenger <NUM> and send a destination-floor registration command by using the personal mobile terminal <NUM>. The radio signal apparatus <NUM>-<NUM> may receive the command and forward the command to an elevator controller (not shown) connected to the radio signal apparatus <NUM>-<NUM>, so as to complete a process of registering a destination floor. A plurality of passengers <NUM> may enter the elevator car <NUM> at the same time; therefore, the foregoing registration process of each passenger <NUM> should be efficiently completed as soon as possible. If the radio signal apparatus <NUM>-<NUM> is still establishing a Bluetooth connection to the personal mobile terminal <NUM> of each passenger <NUM> that is already in the elevator car <NUM> before to send current floor information of the radio signal apparatus <NUM>-<NUM>, it should be understood that first the Bluetooth connection process is time consuming, and an actual floor may have already changed when a personal terminal of a passenger <NUM> receives the floor information. Especially, the Bluetooth connection occupies the connection capacity of the radio signal apparatus <NUM>-<NUM>, and the registration of a destination floor by a personal mobile terminal <NUM> of another passenger <NUM> who newly enters is affected or hindered.

The radio signal apparatus <NUM>-<NUM> continuously broadcasts a current identity <NUM> of the radio signal apparatus <NUM>-<NUM>. The identity <NUM> carries a floor information bit indicating the floor information of the radio signal apparatus <NUM>-<NUM> (that is, indicating floor information of the elevator car <NUM>). Therefore, the personal mobile terminal <NUM> of each passenger <NUM> can perform, without establishing a Bluetooth connection to the radio signal apparatus <NUM>-<NUM>, a scan to recognize the identity broadcasted by the radio signal apparatus <NUM>-<NUM>, and acquire, based on the floor information bit in the recognized identity, the current floor information of the elevator car <NUM>, that is, current floor information of the personal mobile terminal <NUM>.

As the elevator car <NUM> continuously goes up or down, the floor information of the elevator car <NUM> definitely changes dynamically. The floor information bit (for example, "n") of the identity <NUM> of the radio signal apparatus <NUM>-<NUM> may dynamically change accordingly. As such, the floor information bit of the identity <NUM> changes as a floor on which the radio signal apparatus <NUM>-<NUM> is located changes. Correspondingly, the personal mobile terminal <NUM> performs a scan to recognize the dynamically changed floor information bit of the identity broadcasted by the radio signal apparatus <NUM>-<NUM>, so that the personal mobile terminal <NUM> of the passenger <NUM> may dynamically acquire the current floor information of the personal mobile terminal <NUM>.

In an embodiment, a reminder unit may be disposed in the personal mobile terminal <NUM>. When the acquired floor information is close or equal to destination floor information (the destination floor information is known in the personal mobile terminal <NUM>), the reminder unit reminds a passenger <NUM> using the personal mobile terminal <NUM>, for example, sends a vibration and/or sound prompt signal, to remind the passenger <NUM> to leave the elevator car <NUM> or prepare to leave the elevator car <NUM>. To judge whether the acquired floor information is close to the destination floor information, a condition of "close" may be defined according to a factor such as a travel speed of the elevator car. For example, when an absolute value of a difference between the currently acquired floor information and the destination floor information is less than or equal to <NUM> to <NUM>, it is determined that the acquired floor information is close to the destination floor information.

In another alternative embodiment, a reminder unit may be disposed in or coupled to the radio signal apparatus <NUM>-<NUM>. The reminder unit broadcasts reminder information in a sound form when the acquired floor information is close or equal to destination floor information (the destination floor information is known in the radio signal apparatus <NUM>-<NUM>) registered by any passenger.

An example of a method in an embodiment of the present invention is described below with reference to <FIG> and <FIG>.

First, as shown in <FIG>, in step S510, a floor on which an elevator car <NUM> is currently located is acquired. Specifically, a radio signal apparatus <NUM>-<NUM> coupled to an elevator controller of an elevator system may acquire current floor information of the elevator car <NUM> (no matter the elevator car <NUM> is travelling or is stopped) from the elevator controller at any time.

In step S520, a floor information bit in an identity <NUM> of the radio signal apparatus <NUM>-<NUM> is changed based on the acquired floor. For example, the floor information bit "n" is equal to the floor on which the elevator car <NUM> is currently located. Therefore, the floor information bit "n" may be dynamically changed and set.

In step S530, the identity <NUM> including the floor information bit is broadcasted. It should be understood that when the floor information bit "n" changes, the floor information bit "n" in the identity <NUM> broadcasted by the radio signal apparatus <NUM>-<NUM> definitely changes synchronously.

The foregoing steps S510 to S530 may be implemented in the radio signal apparatus <NUM>-<NUM> of the elevator car <NUM>. In a personal mobile terminal <NUM>, the following steps are performed:
In step S540, a scan is performed to recognize the identity <NUM> broadcasted by the radio signal apparatus <NUM>-<NUM> without establishing a connection (for example, a Bluetooth connection) to the radio signal apparatus <NUM>-<NUM>. It should be understood that the dynamically changing identity <NUM> can be dynamically recognized through scanning.

In step S550, the current floor information is acquired based on the floor information bit in the recognized identity <NUM>. It should be understood that the dynamically changing floor information bit can be dynamically recognized and acquired, so that the current floor information can be dynamically acquired. As such, the personal mobile terminal <NUM> can rapidly and conveniently acquire current floor information of the personal mobile terminal <NUM>.

In an example of the application of the acquired floor information, the method further include step S560. In step S560, it is determined, for example, by comparing the acquired current floor information with destination floor information, whether the acquired current floor information is close or equal to the destination floor information.

In step S570, reminder information is sent when the acquired floor information is close or equal to the destination floor information. Specifically, the personal mobile terminal <NUM> may send the reminder information, for example, send reminder information of a sound and/or vibration. A passenger <NUM> may be reminded in time, thereby greatly improving experience of passengers.

It should be understood that the floor information acquired by the personal mobile terminal <NUM> is not limited to the reminder function in the foregoing embodiments, and may further be used as an information basis for developing other functions. Details are not described one by one herein.

An example of the application of the system <NUM> in the embodiment of the present invention is described with reference to <FIG> and <FIG>.

As shown in <FIG>, a radio signal apparatus <NUM>-<NUM> (for example, a BLE module) is mounted in a landing area <NUM> and broadcasts a Bluetooth signal or the like. A passenger <NUM> who enters the landing area <NUM> needs to establish a Bluetooth connection to the radio signal apparatus <NUM>-<NUM> by using a personal mobile terminal <NUM> carried by the passenger <NUM> and send a call request command by using the personal mobile terminal <NUM>. The radio signal apparatus <NUM>-<NUM> may receive the command and forward the command to an elevator controller (not shown) connected to the radio signal apparatus <NUM>-<NUM>, so as to complete a call request process. A plurality of passengers <NUM> may enter the landing area <NUM> at the same time; therefore, the foregoing call request process of each passenger <NUM> should be efficiently completed as soon as possible. If the radio signal apparatus <NUM>-<NUM> is still establishing a Bluetooth connection to the personal mobile terminal <NUM> of each passenger <NUM> that is already in the landing area <NUM> before to send floor information corresponding to the landing area <NUM>, the Bluetooth connection occupies the connection capacity of the radio signal apparatus <NUM>-<NUM>, and the implementation of a call request function by a personal mobile terminal <NUM> of another passenger <NUM> is affected or hindered.

The radio signal apparatus <NUM>-<NUM> continuously broadcasts an identity <NUM> of the radio signal apparatus <NUM>-<NUM>. The identity <NUM> carries a floor information bit indicating the floor information of the landing area <NUM> in which the radio signal apparatus <NUM>-<NUM> (that is, indicating the floor information of the landing area <NUM>). Therefore, the personal mobile terminal <NUM> of each passenger <NUM> of the landing area <NUM> can perform, without establishing a Bluetooth connection to the radio signal apparatus <NUM>-<NUM>, a scan to recognize the identity broadcasted by the radio signal apparatus <NUM>-<NUM>, and acquire, based on the floor information bit in the recognized identity, current floor information of the radio signal apparatus, that is, current floor information of the personal mobile terminal <NUM>.

In another case, when an elevator car <NUM> reaches the landing area <NUM>, especially, when a car door of the elevator car <NUM> and a corresponding floor door are opened, a radio signal broadcasted by the radio signal apparatus <NUM>-<NUM> may cover the inside of the elevator car <NUM>. Therefore, a personal mobile terminal <NUM> of a passenger <NUM> in the elevator car <NUM> may also receive the identity <NUM> broadcasted by the radio signal apparatus <NUM>-<NUM>. Based on the same principle, the personal mobile terminal <NUM> of the passenger <NUM> in the elevator car <NUM> can also acquire the floor information of the landing area <NUM>, that is, acquire the current floor information of the personal mobile terminal <NUM> in the elevator car <NUM>. Further, based on the same principle in the foregoing steps S560 and S570, the reminder function for reaching a destination floor can also be implemented.

It should be understood that as shown in <FIG>, the foregoing radio signal apparatus <NUM>-<NUM> (for example, a BLE module) is further mounted in the elevator car <NUM>.

First, in step S610, an identity <NUM> including a floor information bit is broadcasted. In the step, the radio signal apparatus <NUM>-<NUM> continuously broadcasts the identity <NUM>. It should be understood that because the radio signal apparatus <NUM>-<NUM> is fixedly mounted in a landing area <NUM> on a floor, the floor information bit "n" of the broadcasted identity <NUM> is relatively fixed.

In a personal mobile terminal <NUM>, the following steps are correspondingly performed:
In step S620, the identity <NUM> broadcasted by the radio signal apparatus <NUM>-<NUM> is recognized without establishing a connection (for example, a Bluetooth connection) to the radio signal apparatus <NUM>-<NUM>. Before the identity <NUM> is recognized, a scan for a radio signal broadcasted by the radio signal apparatus <NUM>-<NUM> may further be performed. The scan process is also completed without establishing a connection to the radio signal apparatus <NUM>-<NUM>.

In step S630, current floor information is acquired based on the floor information bit in the recognized identity <NUM>. As such, both a personal mobile terminal <NUM> in the landing area <NUM> and a personal mobile terminal <NUM> in an elevator car <NUM> that reaches the landing area <NUM> (for example, if a car door and a floor door are opened) can rapidly and conveniently acquire current floor information of the personal mobile terminal <NUM>.

In an example of the application of the acquired floor information, the method further includes step S640. In step S640, the personal mobile terminal <NUM> in the elevator car <NUM> determines, for example, by comparing the acquired current floor information with destination floor information, whether the acquired current floor information is equal to the destination floor information.

In step S650, reminder information is sent when the acquired floor information is equal to the destination floor information. Specifically, the personal mobile terminal <NUM> in the elevator car <NUM> may send the reminder information, for example, send reminder information of a sound and/or a vibration. A passenger <NUM> may be reminded in time, thereby greatly improving experience of passengers.

It should be understood that the floor information acquired by the personal mobile terminal <NUM> is not limited to the reminder function in the foregoing embodiments, and may further be used as an information basis for developing other functions. Details are not described one by one herein again.

In the method for acquiring floor information in the foregoing embodiments, floor information can be rapidly and conveniently acquired regardless of dynamic changes of the floor information, and the connection capacity between the personal mobile terminal and the radio signal apparatus does not need to be occupied.

It should be understood that when a component is "connected" or "coupled" to another component, the component may be connected or coupled to the another component directly or via an intermediate component.

It should be understood that in block diagrams and/or flowcharts of the foregoing method, system, and apparatus according to the embodiments of the present invention, these flowchart descriptions and/or blocks of the block diagrams and combinations of the flowchart descriptions and/or block diagrams may be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, a special purpose computer, or another programmable data processing device to produce a machine, such that these instructions, which are executed via the processor of the computer or another programmable data processing device, create components for implementing the functions/operations specified in the flowcharts and/or blocks and/or one or more procedure block diagrams.

These computer program instructions may be stored in a computer readable memory and can instruct a computer or another programmable processor to function in a particular manner, such that these instructions stored in the computer readable memory produce an article of manufacture including instruction components which implement the functions/operations specified in the flowcharts and/or one or more blocks in the block diagrams.

These computer program instructions may be loaded onto a computer or another programmable data processor to cause a series of operational steps to be performed on the computer or the another programmable data processor to produce a computer implemented process such that these instructions which are executed on the computer or the another programmable data processor provide steps for implementing the functions or operations specified in the flowcharts and/or one or more blocks in the block diagrams. It should further be noted that in some alternative implementations, the functions/operations noted in the blocks may occur out of the order noted in the flowcharts. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or these blocks may sometimes be executed in the reverse order, depending upon the functions/operations involved.
