Description:
FIELD OF INVENTION 
       [0001]    This invention relates to a neuron system, more particular, to a neuron system between a neuron device and a cloud server, and comprising a sensor actuator and a communication network (including the internet and wireless network) of an internet of thing. 
       DESCRIPTION OF RELATED ARTS 
       [0002]    Herein a sensor network or a radio frequency identification device (RFID) network is equal to an internet of things. Actually either a sensor technique or a RFID technique is only one of information acquisition techniques. Besides the sensor and RFID techniques, techniques such as GPS, video identification, infrared, laser, scanning and so on, which enable to implement automatic identification and thing-to-thing communication, are all able to be the information acquisition techniques of the internet of things. The sensor network or the RFID network is only an application of the internet of things, but absolutely not whole of the internet of things. 
         [0003]    After long development, each device of the internet network has respective IP address. Meanwhile communication of machine-to-machine (M2M) is also updating; and information interaction and processing can be taken between the devices without personnel participation. 
         [0004]    One of terminals of the internet of things is just an electrical appliance or a similar device we daily used. These “things” communicate each other through infrastructure or a backbone network linked by communication standards such as ZigBee, Sub-GHz, Wi-Fi or PLC. However, main connection devices in the internet of things are arranged at a node called “last inch” of the network. These nodes include: a micro-programmed control unit (MCU), a wireless device, a sensor and an actuator, which are a brain, an eye and a finger of the internet of things respectively. 
         [0005]    The internet of things does not aim to establish connection between a user and a device, because the user does not hope to monitor sensors spread all over a house and sensors spread all over a manufacturing process all the time. The internet of things aims not only to collect important information but also inter-communicate among the devices and make important decisions. 
         [0006]    Challenges for implementing applications of inter-connection of devices for the internet of things are totally different from challenges for the traditional network connection devices. For example, manufacturers of lighting and household appliances have to introduce new network, wireless and embedded software techniques in addition to essential functions into their products. Furthermore, because the device usually cannot be connected to the power supply, its power-supply efficiency is also very important; so that the device may employ an energy collecting apparatus or a battery to work for several years without maintenance or exchanging of battery. 
         [0007]    Developers also need to consider other relative factors, such as cost, the number of elements, performance of MCU, system scale, standard, interoperability, safety, usability and elimination ability of a field failure and so on. Finally, a software shall be able to bridge a device and collect data from sensors, and then to display information on a displayer for a user in a visual way, or to transmit the information to the user&#39;s computer, tablet or cellphone. 
         [0008]    A smart meter is a typical example of the application of the internet of things. Except for simply measuring the power dissipation, the smart meter enables instant communication between an electric power company and a client, for actively shutting down a high-load appliance during peak energy period for saving electric charge of the user and easing the burden of the electric power company. In fact, the smart meter is only one of the applications of the internet of things for a smart house. The internet of things may not only bring advantages to industrial automation, lighting control, smart house, security and monitoring, health and health care, and agricultural applications, but also appear in a wearable application area rising recently. 
         [0009]    Nowadays, applications of the internet of things (sensors related) and internet applications (internet terminals related) cannot combine together quite well. Information collected by the sensors is very hard to be absorbed and utilized by the internet applications via effective and convenient technical methods. 
         [0010]    On the other hand, functions of current internet terminals (mobile terminals such as a cellphone and so on) are increasing complex, many applications, processing and computing are implemented on the terminals independently. However, this kind of implementation obviously increases production cost of the terminal, but also wastes resource due to independent computing and processing of the individual terminal.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0036]    After reading detail descriptions of embodiments in this disclosure incorporated with appending drawings, a better understanding of the characteristics and advantages mentioned above of this invention could be achieved. In the appending drawings, each component may not be drawn to scale and the components with similar related features or characteristics may be marked with the same or approximate reference signs. 
         [0037]      FIG. 1  illustrates a system principle diagram of a preferable embodiment of the neuron system based on an internet of things and a communication network according to this invention. Referring to  FIG. 1 , a neuron system of this embodiment comprises: a plurality of sensor actuators  10 ˜ 1 N, a plurality of neuron devices  30 ˜ 3 N′, a cloud server  4 , an internet of things  2  and a communication network  5 . The communication network  5  may be the internet, a mobile communication network such as a 3G, 4G and the like, a wireless communication network such as a WiFi and the like. 
         [0038]    In this system, the sensor actuators  10 ˜ 1 N collect information about an induction object and upload the information to the corresponding neuron devices  30 ˜ 3 N′. The cloud server  4  arranged in the communication network  5  conducts direct data communication with the neuron devices  30 ˜ 3 N′, uniformly stores and processes information uploaded by the neuron devices  30 ˜ 3 N′. The information uploaded by the neuron devices includes information collected from the sensor actuators and input information from outside. 
         [0039]    The neuron devices  30 ˜ 3 N′ serve as dynamic mobile nodes of the communication network  5 , and conduct information interaction with the cloud server  4  through the communication network  5 . 
         [0040]      FIG. 2  illustrates a structure diagram of a preferable embodiment of the neuron device according to this invention. Please refer to  FIG. 2 . The neuron device  30  (one of the neuron devices  30  is taken as an example for illustration, the other neuron devices have the same structure) comprises: a micro-processor  301 , a receiving module  302 , a transmitter module  303 , an input interface  304 , an output interface  305 , and a storage module  306 . Wherein, the input interface  304  and the output interface  305  are data transmission channels not only between the neuron device  30  and the cloud server  4  but also between the neuron device  30  and an external input device (not shown). The receiving module  302  and the transmitter module  303  are information transmission channels among the neuron device  30 , the cloud server  4  and each of the sensor actuators  10 ˜ 1 N. The storage module  306  is used for storing data downloaded from the cloud server  4  and/or data collected from each of the sensor actuators  10 ˜ 1 N. The micro-processor  301  is respectively connected to the receiving module  302 , the transmitter module  303 , the input interface  304 , the output interface  305  and the storage module  306  through a system bus  307  for controlling these modules and interfaces. 
         [0041]    The neuron device serves as an internet hub for a person and a mobile object and a value-increasing application is transferred to the corresponding cloud server, thereby enabling function simplification, terminal instrumentation and cloud computation of the mobile neuron device. 
         [0042]    The receiving module  302  of the neuron device receives the information collected from the sensor actuators, and stores the collected information in the storage module  306 . The transmitter module  303  of the neuron device transmits control instructions to the corresponding sensor actuator, wherein the control instructions include an adjustment of an implementation threshold value of the sensor actuator. What is stored in the storage module  306  includes recorded static and dynamic information of each of the sensor actuators; and the neuron device may directionally send the information stored in the storage module  306  to a specified IP address, wherein the information includes the recorded static information, dynamic information, and changes of threshold values, etc., of each of the sensor actuators. 
         [0043]    A communication between the neuron device  30  and the sensor actuator  10  may have both wireless and physical interface modes. In the wireless mode, a wireless transceiver module (not shown) is provided in the sensor actuator  10 , and the collected information is sent to the neuron device  30  according to a mobile communication protocol. 
         [0044]    In the physical interface mode, an interface of the sensor actuator  309  (or more) is provided in the neuron device  30 , through which the neuron device  30  is directly connected to the sensor actuator and conducts direct data interaction with the sensor actuator. Of course, the sensor actuator may also be built-in the neuron device  30 . 
         [0045]    The sensor actuator includes a component of sensor itself, and further a plurality of switches (e.g., the Switch  1  to Switch n shown in the Figures). 
         [0046]    Preferably, the neuron device  30  further comprises a call-to-autorun module  308 , which enables to launch an auto-call when the information of the corresponding sensor actuator received by the neuron device exceeds a preset threshold value, and further auto-upload the corresponding information to the cloud server  4  for the cloud server  4  making a decision based on the corresponding information. 
         [0047]    In the internet of things, each of the sensor actuators  10 ˜ 1 N is configured to have an individual IP address, the cloud server  4  and the neuron device  30 ˜ 3 N′ access the sensor actuators  10 ˜ 1 N through the configured IP address. Besides, each of the neuron devices  30 ˜ 3 N′ is configured to have an individual IP address, the cloud server  4  accesses the neuron devices  30 ˜ 3 N′ through the IP address, and the accesses among different neuron devices  30 ˜ 3 N′ are completed through the IP addresses (e.g., for reading information from a storage module of another neuron device). The cloud server  4  receives and uniformly processes information from the neuron devices  30 ˜ 3 N′ and information from the sensor actuators  10 ˜ 1 N′, and sends processed results back to the corresponding neuron devices  30 ˜ 3 N′ and sensor actuators  10 ˜ 1 N′. In addition to building communication connection with the neuron devices and the sensor actuator through the communication network  5 , the cloud server  4  may build communication connection with the internet of things directly. 
         [0048]    Preferably, the cloud server  4  is composed of a plurality of virtual hosts with a respective IP address, wherein each of the virtual hosts corresponds to one neuron device to accomplish necessary value-added application. Each virtual host accesses the corresponding neuron device through the respective IP address. The value-added applications of the neuron device are all carried out based on the corresponding virtual host. The neuron device is only used as a neuron device for data read-in, data read-out, data collection and publication (published to the cloud or other authorized mobile terminals and neuron devices), data caching, data monitoring, communicating with other neuron devices and real-time or periodically transmitting data to the cloud. All the advanced computations, analysis and value-added applications are accomplished by the virtual host corresponding to the cloud. 
         [0049]    A core component of an intelligent wearable device is a computer which may surf the internet at any time. However, there is a contradiction between the requirement for increasing strong functions of a local computer to meet increasing complex needs and the requirement for portability of the wearable device. When the internet speed of a mobile network reaches a certain degree, one solution for the above problems is to employ a high-speed mobile network to merely take the neuron device as an internet hub, an output-input device and a caching device, and to employ the cloud server to complete all complicated computation, which enables to solve the problems mentioned above quite well. 
         [0050]    Because the neuron devices with simplified function serve as one&#39;s internet hub, data from various sensors on one&#39;s body and various data of one&#39;s body may be transmitted to the virtual host of the cloud by the neuron devices in real time, the virtual host enables to complete various kinds of value-added applications, send results back to the neuron devices through the mobile network, and then distribute the results to each part of body. For instance, the results are distributed to eyes for viewing, learning or playing, to muscle for muscle status reminder, to earphones for enjoying music and language, and to every sense organ of the body for experiencing virtual reality. 
         [0051]    Information exchange of mobile objects, e.g., information exchange between the mobile object with an object, a person and a network, fails to adequately use the mobile network. By installing an instrumentalized neuron device in a mobile object as the internet hub, it may not only send information of the mobile object to a person, an object or a network in time, but also carry out value-added applications for completing complicated analysis and computation immediately, so as to improve and develop applications of the internet of things. 
         [0052]    Because the neuron device with simplified functions greatly decreases cost of the neuron device without limiting its powerful computing capability, the neuron device may be widely applied in various movable objects, to collect data from various sensor actuators on various objects for a long time, and to proceed immediate and long-term accumulated analysis and computation, and then to promote applications of big data. 
         [0053]    From this scheme, one can see that the neuron device may be used as a node equipment of various wireless networks. As a dynamic mobile node in a dynamic wireless network, the neuron device establishes a protocol (at the place where an operator&#39;s mobile network could not cover and a communication mechanism could be established with these nodes). As long as the mobile neuron device approaches the “nodes”, the neuron device could read data in the nodes, store the data in its storage module and automatically send the data to an assigned IP address when there is a network communication. 
         [0054]      FIG. 3  is shown another structure of the system. The difference between the implantations in  FIG. 3  and  FIG. 1  lies in the position of the internet of things; in  FIG. 3 , the sensor actuators may further establish communication connections therebetween through the internet of things. 
         [0055]    Following are embodiments of applications according to this invention. 
       Embodiment 1 
       [0056]    A neuron device is installed in a vehicle (such as a car, a ship and an aircraft). An input interface of the neuron device accesses a station announce button of a bus driver to dispatch (their neuron device) to broadcast manual (subjectively judged by the bus driver) location information for the passengers inside or outside the bus through the neuron device. 
         [0057]    The neuron device in the bus (such as via a position sensor actuator) establishes auto-call mechanism with the neuron device (such as via a position sensor actuator) carried by the passengers, confirms dynamic busload of the vehicle and reports to a person, an object or an institute as needed. The position sensor actuator in the bus periodically sends position information of the bus to those who reserves this information through the neuron device; the person who reserves position information of the bus may actively call the neuron device in the bus to inquire position information of the bus. The person who reserves information could be family relation who cares the geographic position of a private car, could be a passenger who cares specific geographic position information of coming bus, or could be a logical company who cares geographic position information of cargo transportation monitored.
