In addition, the GPS in the market is at least about hundred yuan, the positioning of a mobile phone base station is slightly cheaper, more than fifty yuan is needed, and the GPRS/3G flow cost and the use cost are high in each month.

An electronic bus stop board scheme is disclosed in a patent document (application number 201410144578.4) of electronic bus stop board equipment based on RFID, and is realized based on an RFID technology, so that the cost is remarkably reduced. However, the electronic bus stop board is still only an electronic bus stop board with single function, more values are not deeply excavated, and particularly, by means of the technical characteristics of electronic bus stop board equipment and the characteristics of geographic distribution, and the advantage of high investment enthusiasm in the aspect of intelligent buses in a plurality of cities is achieved, so that a wide prospect of application of positioning tracking service in the city range is developed.

In the patent document of 'positioning and managing system for coal mine personnel based on ZigBee technology' (application number 201110454284.8), a positioning technology based on ZigBee technology is disclosed, which has the advantages of reduced cost and lower power consumption, but is limited to small-scale application, if the positioning technology is used in urban scale, a large number of infrastructures such as base stations and the like need to be specially arranged, and the investment and engineering quantity are huge, so that the positioning technology is impractical.

For very small probability events such as child missing, old man missing, bicycle and other articles missing, the user is required to frequently remember to charge the articles, otherwise, the articles can lose effect due to the fact that the batteries are used up, and the convenience of the user is greatly reduced.

Optionally, the identification information of the electronic bus stop board is a stop board ID number and an IP address of the electronic bus stop board, and the electronic bus stop board sends the stop board ID number, the IP address and a preset data packet to the server together. The server is used for determining the position information of the target object according to the station board ID number, the IP address and the preset data packet. The network communication module 200 may be a GPRS/3G network communication module, and may enable the electronic bus stop board to send the identification information of the electronic bus stop board and the preset data packet through the GPRS/3G network.

The microprocessor 300 is connected to the wireless communication module 100 and the network communication module 200, and is used for controlling the wireless communication module 100 to detect whether a target object exists in a preset distance range of the electronic bus stop board, and controlling the network communication module 200 to send identification information of the electronic bus stop board and a preset data packet of the wireless module to the server.

The wireless communication module 100 and the network communication module 200 are both connected to the microprocessor 300 (Micro Control Unit, abbreviated as MCU), the microprocessor controller 300 is a core for controlling the wireless communication module 100 and the network communication module 200, the wireless communication module 100 and the network communication module 200 are hardware circuits for completing communication by the microprocessor 300, the wireless communication module 100 is controlled to detect whether a target object exists in a preset distance range of the electronic bus stop board, and the network communication module 200 is controlled to send identification information of the electronic bus stop board and a preset data packet of the wireless module to the server.

In this embodiment, whether a target object exists in a preset distance range of an electronic bus stop board is detected by the wireless communication module 100, the target object includes a first target object and a second target object, the first target object is a bus, the second target object is an object different from the bus, when the wireless communication module detects that the target object exists in the preset distance range of the electronic bus stop board, the identification information of the electronic bus stop board and a preset data packet sent by a wireless module arranged on the target object are sent to the server by the network communication module 200, the server is used for determining the position information of the target object according to the identification information of the electronic bus stop board and the preset data packet, the preset data packet is a data packet with a preset format and used for identifying the information of the wireless module, the wireless communication module and the network communication module are connected through the microprocessor 300 to control the wireless communication module to detect whether the target object exists in the preset distance range of the electronic bus stop board, and the network communication module is controlled to send the identification information of the electronic bus stop board and the preset data packet of the wireless module to the server, so that a positioning function of the electronic bus stop board is achieved, and a positioning function of the electronic bus stop board is further achieved.

As an alternative embodiment, the wireless communication module 100 is configured to receive a preset data packet sent by the wireless module according to a first preset period, where the wireless module enters the awake state from the sleep state to send the preset data packet every the first preset period.

The wireless module is in a dormant energy-saving state at ordinary times, namely, unnecessary energy consumption of the wireless module is reduced to the greatest extent, the service life of a battery is prolonged, the times of battery replacement or charging of a user are reduced, and the user obtains better use experience. A first preset period is adopted to wake up at fixed time to enter a wake-up state from a sleep state. Immediately after the wireless module wakes up, a preset data packet is sent to the wireless communication module 100 of the electronic bus stop board. When the wireless communication module 100 receives the preset data packet, the ID number and the IP address of the electronic bus stop board are attached, and the preset data packet and the ID number and the IP address of the electronic bus stop board are sent to the server through the network communication module 200, so that the server is used for determining the position information of the target object according to the preset data packet of the wireless module and the ID number and the IP address of the electronic bus stop board.

As an alternative embodiment, the first preset period is 0.3 seconds to 9 seconds.

The wireless module is in a dormant energy-saving state at ordinary times, and adopts a periodic timing awakening working mode, wherein the first preset period is 0.3 to 9 seconds. Optionally, the wireless module wakes up through a microprocessor. The wireless module immediately transmits a preset data packet to the wireless communication module 100 of the electronic bus stop board after the wireless module wakes up, if the interval time for waking up the wireless module is longer than 0.3 to 9 seconds, the preset data packet may be missed when the wireless module passes through a communication coverage area of the electronic bus stop board, thereby losing one opportunity for locating a target object; if the interval of waking up the wireless module is shorter than 0.3 to 9 seconds, this means that the wireless module will transmit data packets more densely, consume more energy, and cause frequent charging or battery replacement, thus increasing the burden of users. Considering the moving speed of the target object and the size of the communication coverage area of the electronic bus stop board, the first preset period is selected within 0.3 to 9 seconds, so that the higher receiving accuracy of the preset data packet can be achieved, the wireless module can save energy to the maximum extent, and the burden of a user is reduced.

As an alternative embodiment, the microprocessor 300 is configured to control the wireless communication module 100 to send an acknowledgement packet to the wireless module after receiving the preset packet, where the acknowledgement packet is used to indicate that the wireless communication module 100 has received the preset packet, and the wireless module enters the awake state from the sleep state to send the preset packet to the wireless communication module 100 according to a second preset period after receiving the acknowledgement packet, and when the wireless module has not received the acknowledgement packet and waits for the time to receive the acknowledgement packet to exceed the preset waiting time, send the preset packet to the wireless communication module 100 according to the first preset period, where the second preset period is greater than the first preset period.

The wireless module immediately shifts to the data reception state after transmitting the preset data packet to the wireless communication module 100. The microprocessor 300 is configured to control the wireless communication module 100 to send an acknowledgement packet to the wireless module after receiving the preset data packet, where the acknowledgement packet is used to indicate that the wireless communication module 100 has received the preset data packet. Because the preset data packet of the wireless module is received by the electronic bus stop board, the wireless module sends the preset data packet to have no meaning on the positioning function of the electronic bus stop board before leaving the coverage area of the current electronic bus stop board and entering the coverage area of the next electronic bus stop board, after the wireless module receives the confirmation data packet, the wireless module starts a long dormancy wakeup interval, sends the preset data packet to the wireless communication module 100 according to a second preset period, and the second preset period is larger than the first preset period, so that unnecessary sending of the preset data packet by the wireless module is reduced, the effect of saving battery energy of the wireless module is achieved, and meanwhile, collision of the preset data packet can be reduced for places where the wireless module is dense. Optionally, if the wireless module does not receive the acknowledgement data packet and the waiting time exceeds 50% of the time for receiving the acknowledgement data packet in normal time, the wireless module enters a normal sleep state, that is, the wireless module enters an awake state from the sleep state again according to the first preset period, and further sends the preset data packet to the wireless communication module 100, so that the wireless module of the electronic bus stop board achieves the energy saving effect.

As an alternative embodiment, the second preset period is greater than 9 seconds and less than 300 seconds.

After the wireless module receives the acknowledgement packet, the wireless module starts a long sleep wakeup interval, and sends a preset packet to the wireless communication module 100 according to a second preset period.

The electronic bus stop boards are respectively an uplink electronic bus stop board through which a bus runs upward and a downlink electronic bus stop board through which a bus runs downward, and the uplink electronic bus stop boards correspond to the downlink electronic bus stop boards opposite to the road. If the uplink electronic bus stop board and the corresponding downlink electronic bus stop board both receive the preset data packet and send the confirmation data packet to the wireless module at the same time aiming at the preset data packet, the wireless module can collide when receiving the confirmation data packet, and then the confirmation data packet cannot be received.

The wireless module alternately sends preset data packets to the first preset address and the second preset address, the wireless communication module 100 of the uplink electronic bus stop board and the wireless communication module 100 of the corresponding downlink electronic bus stop board simultaneously monitor whether the first preset address and the second preset address receive the preset data packets or not, the wireless communication module 100 of the uplink electronic bus stop board only sends acknowledgement data packets to the wireless module when judging that the first preset address receives the preset data packets, and the wireless communication module 100 of the downlink electronic bus stop board only sends acknowledgement data packets to the wireless module when judging that the second preset address receives the preset data packets, so that the problem that the uplink electronic bus stop board and the corresponding downlink electronic bus stop board simultaneously receive the preset data packets and simultaneously send acknowledgement data packets to the wireless module to cause signal conflict is avoided, and the wireless module cannot correctly acknowledge the data packets on the contrary.

As an alternative embodiment, the wireless communication module 100 is further configured to receive a preset data packet sent by the wireless module according to a third preset period, where the wireless module is configured to detect, by using the vibration sensor, a vibration signal of the target object, and if the wireless module does not detect the vibration signal of the target object within the preset time, enter the awake state from the sleep state according to the third preset period to send the preset data packet to the wireless communication module 100, and if the wireless module detects the vibration signal of the target object again, send the preset data packet to the wireless communication module 100 according to the first preset period, where the third preset period is greater than the first preset period.

The wireless module also includes a vibration sensor for detecting a vibration signal of the wireless module. If the vibration sensor does not receive the vibration signal in the preset time, the microprocessor judges that the wireless module is in a static state at the moment, and further determines that the target object is in the static state. When the target object is in a static state, whether the target object is in a preset distance range of a certain electronic bus stop board or not, the wireless module frequently transmits data packets to the system in a preset distance range of any electronic bus stop board, and at the moment, the microprocessor wakes the wireless module to enable the wireless module to enter a wake-up state from a dormant state by adopting a third preset period, and transmits the preset data packets to the wireless communication module 100, wherein the third preset period is larger than the first preset period, so that the transmission times of the wireless module for transmitting the preset data packets are reduced, and the battery energy of the wireless module is further saved. When the wireless module detects the vibration signal of the target object again, the target object is likely to start moving again, and the preset data packet is sent to the wireless module again according to the first preset period, so that the battery energy of the wireless module is saved.

If the vibration sensor does not receive the vibration signal within 60-600 seconds, the microprocessor judges that the wireless module is in a static state at the moment, and then the target object is determined to be in the static state. At this time, the microprocessor wakes up the wireless module by using a wake-up period greater than 9 seconds and less than 600 seconds to make the wireless module enter the wake-up state from the sleep state, and sends a preset data packet to the wireless communication module 100. The wireless communication module 100 receives a preset data packet transmitted by the wireless module according to a wake-up period of more than 9 seconds and less than 600 seconds to save battery energy of the wireless module. When the wireless module detects the vibration signal of the target object again, the wireless module returns to the original wake-up time interval again, and a preset data packet is sent to the wireless module according to 0.3 to 9 seconds so as to save the battery energy of the wireless module.

The display module of the electronic bus stop board is used for displaying real-time running position information of the bus. Each station name in the bus route on the electronic bus station board corresponds to one light emitting diode and is used for displaying real-time running position information of the bus. For example, when the light emitting diode on the bus is on, the distance range of the electronic bus stop board indicating that the bus runs to the stop name corresponding to the light emitting diode is preset. The network communication module 200 sends the identification information and the preset data packet of the electronic bus stop board to the server when the wireless communication module 100 detects that the target object exists in the preset distance range of the electronic bus stop board, and the server is used for determining the position information of the bus according to the identification information and the preset data packet of the electronic bus stop board. Optionally, the server collates and summarizes the data uploaded by each electronic bus stop board, so that the real-time running position information of the buses on the public lines can be obtained, and the server sends the real-time running position information of the buses to the related electronic bus stop boards and displays the information through the display modules of the electronic bus stop boards. When a plurality of bus lines share one electronic bus stop board, the display modules corresponding to the bus lines are cascaded. When one more bus route is arranged on the electronic bus stop board, only one bus real-time position display module is needed to be added, and other parts are shared. The electronic bus stop board system has the advantages that the configuration of the electronic bus stop board system is simplified to the greatest extent, the manufacturing cost is reduced, the electronic bus stop board system is simple in structure, flexible and convenient to install, strict requirements on bearing, installation size and the like are not met, the main body shell of the old stop board can be used continuously, waste is avoided, in addition, the power consumption of the display module is low, the power supply problem of the electronic bus stop board is solved more easily, and the electronic bus stop board system is suitable for comprehensive popularization and popularization.

The display module can also display the time expectation that the bus closest to the electronic bus stop board reaches the electronic bus stop board on the public traffic line. The network communication module 200 sends the identification information of the electronic bus stop board and the preset data packet sent by the wireless module to the server, the server is used for obtaining that one bus closest to the electronic bus stop board is located at a plurality of stations from the station according to the identification information of the electronic bus stop board and the preset data sent by the wireless module, adding the average running time of every two stations stored before to further obtain the time expectation that the bus closest to the electronic bus stop board arrives at the electronic bus stop board on the public traffic line, and sending the time expectation to the electronic bus stop board for displaying.

For example, when the bus starts from the start point, the running mode of the bus is determined to be the uplink running, and when the bus starts from the end point, the running mode of the bus is determined to be the downlink running. If the bus is running in an uplink mode, when the bus runs within the preset distance range of the electronic bus stop board, the preset data packet sent by the wireless module on the bus is received by the wireless communication module 100 of the electronic bus stop board. The wireless communication module 100 forwards the preset data packet with the ID number and the IP address of the electronic bus stop board to the server, and the server sends a command to all the electronic bus stop boards on the bus line, and lights the light emitting diodes corresponding to the stop names of the electronic bus stop boards, so as to indicate that the bus runs to the electronic bus stop boards. When the wireless module of the bus continues to run to the preset distance range of the next electronic bus stop board, the preset data packet sent by the wireless module on the bus is received by the next electronic bus stop board and is transferred to the server, the server determines that the bus runs to the next electronic bus stop board again, and accordingly the server sends a command to all the uplink electronic bus stop boards of the line, and the LED corresponding to the stop name of the next electronic bus stop board is lightened. If no other buses arrive at the electronic bus stop board at this time, but the next electronic bus stop board is not reached, the server sends a command to all the electronic bus stop boards on the bus route, and the LEDs corresponding to the stop names of the electronic bus stop boards are turned off, so that the electronic bus stop board has no buses, and the electronic bus stop board on the bus route displays real-time running position information of buses on the bus route, thereby serving a waiting person. Alternatively, the real-time running position information of the bus of the server can also be queried by the user through a terminal, such as the APP of the mobile terminal of the user, where the terminal is not limited to a mobile phone, a tablet computer, and the like.

Meanwhile, the chip nRF24L01+ can be in an energy-saving dormant state most of the time. The chip nRF24L01+ has ultralow power consumption, the receiving current of the chip nRF24L01+ is 13.5mA, the transmitting current of the chip nRF24L01+ is 0dBm, the transmitting current of the chip nRF24L01+ is 11.3mA, the current of a power-down mode is only 900nA, and a longer dormancy wakeup time interval is adopted after the wireless module is in a static state and the wireless module receives a confirmation data packet, so that the energy consumption is further reduced, and the wireless module can continuously work for about one year when being charged or being replaced. In addition, the chip nRF24L01+ is low in price, few in peripheral elements and only 4X4mm QFN package, and is very suitable for cheap and small products. The short-distance wireless communication part components and parts, together with the antenna, can be arranged on a PCB (printed circuit board) with the size of 15mm and 20mm, and the electronic bus stop board system has an address space of 5 bytes, so that the electronic bus stop board system can accommodate huge product quantity.

If the bus wireless module 6, the positioning tracking wireless module 7, the light control wireless module 8, the door and window state wireless module 9, the gas alarm wireless module 10 and the well lid wireless module 11 do not receive the receiving confirmation data packet, and after the waiting time exceeds 50% of the average receiving time, the wireless module normally shifts to a dormant state to wait for the next awakening, so that the positioning function of the electronic bus stop board achieves the energy-saving effect, the service life of a battery is prolonged, the probability of signal air collision is reduced, and the system can accommodate more wireless modules.

Optionally, the packet occupation time of one wireless module is 1ms, the wake-up interval time is the shortest 0.3 seconds, and in the coverage area of one internet of things station, 300 wireless modules can be simultaneously accommodated theoretically. In addition, after receiving the confirmation data packet, a long sleep mechanism and a static state long sleep mechanism are adopted, so that the system has enough capacity to be applied to places with dense personnel without signal blockage.

In many cities, the bus stop board 2 does not provide power, and the electronic bus stop board system is implemented in a simplest mode of taking electricity from a nearby street lamp. Because the street lamp only has electricity at night, a battery is also required to be matched for daytime use. The power supply part of the electronic bus stop board 2 is provided with a battery charging and protecting circuit besides the voltage stabilizing function. The station with difficulty in getting electricity to the street lamp can also be provided with a solar cell panel and a battery to solve the power supply problem of the electronic bus stop board.

The well lid wireless module 11 is in a preset distance range of the electronic bus stop board 2A, and can send preset data packets to the electronic bus stop board 2A and receive acknowledgement data packets sent by the electronic bus stop board 2A.

The light control wireless module 8, the door and window state wireless module 9 and the gas alarm wireless module 10 of the embodiment belong to intelligent home wireless modules. The preset data packet sent by the intelligent home wireless module is particularly marked as an exclusive data packet in the data packet, only the intelligent home controller 3 with the binding relation can process the data packet, and the intelligent home controller 3 or the electronic bus stop board 2 which does not establish the binding relation with the data packet can be directly discarded and not processed when receiving the exclusive data packet. The exclusive data packet sent by the light control wireless module 8A, the door and window state wireless module 9A and the gas alarm wireless module 10A is processed by the intelligent home control program only after being received by the intelligent home controller 3A, and a confirmation data packet is sent back to the intelligent home control program; the exclusive data packet sent by the light control wireless module 8B, the door and window state wireless module 9B and the gas alarm wireless module 10B is processed by the intelligent home control program only after being received by the intelligent home controller 3B, and a confirmation data packet is sent back to the intelligent home control program. The smart home controller 3 or the electronic bus stop board 2 which does not establish a binding relationship with the smart home controller will not process and send back a confirmation data packet even if receiving the exclusive data packet.

Under the preset condition, the preset data packet of the intelligent home wireless module is not marked as a special data packet, but is sent out in a format of a common data packet. At this time, after the intelligent home controller 3 or the electronic bus stop board 2 which does not establish a binding relation with the intelligent home controller is received, the intelligent home controller or the electronic bus stop board is attached with an ID number and an IP address of the intelligent home controller, the intelligent home controller sends a data packet to the server 1, and a confirmation data packet is sent back.

For example, in the case of an emergency in which a gas leakage is detected, the gas alarm wireless module 10A in fig. 4 sends out a preset data packet containing gas leakage alarm information, which is not marked as a dedicated data packet, but is sent out in a format of a normal data packet. After the common data packet is received by the intelligent home controller 3A, the intelligent home controller 3A sends out a fuel gas leakage alarm, and after the ID number and the IP address of the intelligent home controller 3A are attached, the common data packet is sent to the server 1, the server 1 gives the data to the intelligent home program module 14 for processing according to the type of the data packet as the intelligent home application type, and the intelligent home program module 14 can forward the information to the corresponding mobile phone APP according to the preset; after the common data packet is received by the intelligent home controller 3B, the intelligent home controller 3B sends an alarm of neighbor gas leakage, and sends the common data packet to the server 1 after the ID number and the IP address of the intelligent home controller 3B are attached, the server 1 gives the common data packet to the intelligent home program module 14 for processing according to the module type of the common data packet, and the intelligent home program module 14 forwards the information to the mobile phone APP corresponding to the gas alarm wireless module 10A and the mobile phone APP corresponding to the intelligent home controller 3B according to preset settings.

When the gas alarm wireless module 10B sends out the exclusive data packet and cannot receive the confirmation data packet for a long time, the sent preset data packet is not marked as the exclusive data packet any more, but is sent out in the format of the common data packet. After the common data packet is received by the intelligent home controller 3A, the intelligent home controller 3A attaches the ID number and the IP address of the intelligent home controller 3A, sends the common data packet to the server 1, the server 1 gives the data to the intelligent home program module 14 for processing according to the type of the data packet module, and the intelligent home program module 14 can forward the information to the mobile phone APP corresponding to the gas alarm wireless module 10B according to the preset setting, so that the owner of the intelligent home controller 3B can be reminded that the intelligent home controller may have some problems. Further assume that the gas alarm wireless module 10B is stolen, when it passes through the electronic bus stop board 2B, its ordinary data packet is forwarded to the server 1 by the electronic bus stop board 2B, and then forwarded to the corresponding mobile phone APP, so as to remind the host that the gas alarm wireless module 10B has left home and arrived at other places, and can further perform positioning tracking on the gas alarm wireless module. In a word, after the electronic bus stop board system is added with the intelligent home controller 3, the functions of the system are enhanced and perfected, and the characteristics of the system are utilized in turn, so that the intelligent home controller 3 can have unexpected functions, and the two complement each other.

For example, the well lid wireless module 11 is within a preset distance range of the electronic bus stop board 2A, after the electronic bus stop board 2A receives a preset data packet sent by the electronic bus stop board 2A, the electronic bus stop board 2A attaches an ID number and an IP address of the electronic bus stop board 2A and sends the data packet to the server 1, and sends back a confirmation data packet to the well lid wireless module 11. The server 1 transfers the data packet to the data forwarding application program module according to the preset data packet belonging to the data forwarding application type, and the data forwarding application program module forwards the preset data packet to the well lid management program 16 according to the preset corresponding relation between the well lid wireless module 11 and the application program 'well lid management program 16' on the internet, so that the application of the internet of things for well lid management is realized. Compared with the method for establishing the data connection between the well lid and the well lid management program 16 through GPRS, the method has great advantages in the aspects of difficulty, cost, power consumption, use fee, system maintenance burden and the like.

The electronic bus stop board function of the embodiment is realized as follows: the composition, sequence, ID number, stop board position coordinate information of the electronic bus stop board 2 of each bus route and the module ID number of the bus wireless module 6A installed by the bus are all input into the server 1 in advance. Wherein the bus wireless module 6 is mounted on a bus. When the bus equipped with the bus wireless module 6A runs within the short-distance wireless communication range of the electronic bus stop board 2A, the electronic bus stop board 2A receives a preset data packet sent by the bus wireless module 6A, and then forwards the preset data packet together with the ID number and the IP address of the electronic bus stop board 2A to the server 1. The server 1 processes the preset data packet by the electronic bus stop board program module 12 according to the module type of the preset data packet as the electronic bus stop board type, and the electronic bus stop board program module 12 can determine that the bus is in the short-distance wireless communication range of the electronic bus stop board 2A at the moment. The server 1 can learn the position of the bus station reached by each bus according to the data uploaded by each electronic bus station board 2.

Optionally, whether the bus is running up or down is determined according to whether the bus starts from the starting point or the ending point. The server 1 can further summarize and sort out the real-time running position data of the buses on the upward and downward routes. If the bus provided with the bus wireless module 6A is in an uplink state, and the bus runs to the electronic bus stop board 2A at the moment, the server 1 downloads a command, and lights the LEDs corresponding to the electronic bus stop board 2A on all uplink electronic bus stop boards of the bus line, so that the bus with the uplink state runs to the bus stop. When the bus equipped with the bus wireless module 6A continues to travel and enters the next station (if the bus is an electronic bus stop board 2B), the electronic bus stop board 2B receives a preset data packet sent by the bus wireless module 6A, and then forwards the preset data packet together with the ID number and the IP address of the electronic bus stop board 2B to the server 1, the server 1 can determine that the bus equipped with the bus wireless module 6A is running to the electronic bus stop board 2B, the server 1 downloads a command, and lights the light emitting diodes corresponding to the electronic bus stop boards 2B on all the uplink electronic bus stop boards of the bus line, which indicates that the uplink bus is running to the electronic bus stop board 2B. Meanwhile, if no buses in other uplink states of the bus line reach the electronic bus stop board 2A, the LEDs corresponding to the electronic bus stop board 2A on all uplink electronic bus stop boards of the bus line are turned off, so that the bus is not in the bus station. And the like, displaying the real-time running position information of the bus through the light emitting diode, and further serving the waiting person. Optionally, the server 1 provides real-time running position information of the bus to the client program 5 and the mobile terminal APP4, and the mobile terminal APP4 can be a mobile phone, a tablet computer or the like, so that a user can inquire the real-time running information of the bus through the mobile phone, and convenience is brought to citizens to take buses.

The bus wireless module 6 judges whether the bus is in a static state through the vibration sensor, if the bus does not detect the vibration signal within a preset period of 60 seconds to 600 seconds, the bus can be judged to be in the static state, and the bus wireless module 6 adopts a longer dormancy awakening period of 9 seconds to 300 seconds; if the bus wireless module 6 receives the confirmation data packet of the electronic bus stop board 2, the bus wireless module 6 adopts a longer dormancy awakening period of 9 seconds to 600 seconds, thereby reducing unnecessary data transmission, saving the energy of a battery, reducing the times of charging or replacing the battery, and being convenient to use.

The electronic bus stop board system has a positioning and tracking function. The positioning and tracking functions of the electronic bus stop board system of the embodiment are realized as follows: after receiving the preset data packet sent by the electronic bus stop board 2 or the intelligent home controller 3 and the identification information of the electronic bus stop board 2 or the intelligent home controller 3 forwarded by the positioning and tracking wireless module 7, the server 1 gives the preset data packet to the positioning and tracking application module 13 for processing according to the module type information in the preset data packet, and the positioning and tracking application module 13 can determine that the target object provided with the positioning and tracking wireless module 7 is in the short-distance wireless communication range of the electronic bus stop board 2 or the intelligent home controller 3. The server 1 records the position coordinates of the electronic bus stop boards 2 or the position coordinates of the intelligent home controllers 3 where the target objects are located each time and the time within the preset distance range of the electronic bus stop boards 2 or the time within the preset distance range of the intelligent home controllers 3 by combining the prestored coordinate data of each electronic bus stop board 2 or the coordinate data of the intelligent home controllers 3 obtained by building a two-dimensional coordinate system for the urban map, and then the movement track data of the target objects can be generated. The motion trail data of the target object can be queried by the client program 5 or the mobile terminal APP4, and the positioning query and the history trail query of the target object provided with the positioning tracking wireless module 7 can be realized. Optionally, the coordinate data of the electronic bus stop board 2 or the coordinate data of the intelligent home controller 3 are compared with the set electronic fence coordinate data, so that the electronic fence alarm function can be realized.

The formats of preset data packets of the bus wireless module 6, the positioning tracking wireless module 7, the light control wireless module 8, the door and window state wireless module 9, the gas alarm wireless module 10 and the well lid wireless module 11 are as follows: "Starter, module ID number, module type, data type (if any), data (if any), terminator". The module type is divided into an electronic bus stop board application type, a positioning tracking application type, an intelligent home application type and a data forwarding application type according to the application of the Internet of things to which the wireless module belongs, and the server 1 respectively transmits preset data packets to the electronic bus stop board program module 12, the positioning tracking application program module 13, the intelligent home program module 14 and the data forwarding application program module 15 for processing according to the module type. The "data type" is used to divide the preset data packet into: proprietary data packets and normal data packets. The preset data packets sent by the bus wireless module 6, the positioning tracking wireless module 7 and the data forwarding wireless module 15 are set to be common data packets. The light control wireless module 8, the door and window state wireless module 9 and the gas alarm wireless module 10 which are in binding relation with the intelligent home controller 3 send out preset data packets which are set as exclusive data packets, and the binding relation is set during equipment installation and debugging. The intelligent home controller 3 and the positioning tracking wireless module 7 which establish the binding relation, the light control wireless module 8, the door and window state wireless module 9 and the gas alarm wireless module 10 all store ID numbers of the other side, and the intelligent home controller 3 and the positioning tracking wireless module 7, the light control wireless module 8, the door and window state wireless module 9 and the gas alarm wireless module 10 judge whether the two sides belong to the binding relation or not through the ID numbers.

Optionally, if the electronic bus stop board 2 receives the exclusive data packet, the exclusive data packet is directly discarded and not processed; if other data packets are received, the ID number and the IP address attached to the station board are forwarded to the server 1, and the receiving confirmation data packet is sent back to the wireless module. The intelligent home controller 3 processes the preset data packet sent by the wireless module with the binding relation with the intelligent home controller according to a preset program, processes the preset data packet sent by the wireless module without the binding relation with the intelligent home controller, if the preset data packet is a special data packet, directly discards the preset data packet without processing the special data packet, attaches the ID number and the IP address of the intelligent home controller 3 to other preset data packets, forwards the other preset data packets to the server 1, and sends back a reception confirmation data packet to the wireless module. The data format of the acknowledgement packet is: "Starter, electronic bus stop board or ID number of the intelligent home controller 3, data (if any), ending symbol". Optionally, when the light control wireless module 8, the door and window state wireless module 9 and the gas alarm wireless module 10 cannot receive the confirmation data packet more than a certain number of times, or in an emergency, the preset data packet which should be sent out in the format of the exclusive data packet can be sent out according to the format of the common data packet. If the positioning and tracking wireless module 7A has a binding relationship with the intelligent home controller 3A, the positioning and tracking wireless module 7A receives a confirmation data packet sent back by the intelligent home controller 3A, which indicates that the positioning and tracking wireless module 7A is within a preset distance range of the intelligent home controller 3A, and the positioning and tracking wireless module 7A can adopt a longer sleep wakeup interval. For example, when the old people are outside, the preset data packet can not be sent too long to prevent missing a positioning opportunity, but when the old people are at home, the preset data packet can be sent once at intervals of a long time, so that the aim of saving energy to the greatest extent is fulfilled.

For example, the door and window state wireless module 9A, the light control wireless module 8A and the gas alarm wireless module 10A respectively establish a binding relationship with the intelligent home controller 3A, the data types of the preset data packets sent by the three wireless modules are dedicated data packets, the intelligent home controller 3A receives the preset data packets sent by the three wireless modules, processes the preset data packets according to a predetermined program, and can send confirmation data packets or control commands to the preset data packets, so that various functions of the intelligent home controller 3, such as detection of the door and window state, switching on/off of a lamp, gas alarm and the like, are realized. And when the intelligent home controller 3B, the electronic bus stop board 2B and the like receive exclusive data packets of the door and window state wireless module 9A, the light control wireless module 8A and the gas alarm wireless module 10A, the exclusive data packets are directly discarded and not processed. However, when the door and window state wireless module 9A, the light control wireless module 8A and the gas alarm wireless module 10A cannot receive the reception confirmation data packet for a plurality of times, or in an emergency, the door and window state wireless module 9A, the light control wireless module 8A and the gas alarm wireless module 10A can convert the preset data packet into the common data packet format to send, so that if the data packet is received by the smart home controller 3B or the electronic bus stop board 2B, the data packet can be also transferred to the mobile terminal APP4. For example, the intelligent home controller 3A fails, or after a wireless module installed on an article is stolen along with the article, the wireless module is far away from the intelligent home controller 3, and the wireless module is turned to a data packet sent in a common data packet format, so that the data packet is received by the other intelligent home controller 3 or the electronic bus stop board 2 and forwarded to the server 1, thereby achieving the purpose of positioning and tracking. For another example, when the gas alarm wireless module 10A detects that gas leaks to send out an alarm, the gas alarm wireless module also sends out the gas alarm in a common data packet format, at this time, even if the intelligent home controller 3A has a fault, if the intelligent home controller 3B or the electronic bus stop board 2B can receive the gas alarm signal, the gas alarm wireless module can also send out an alarm signal of gas leakage of a neighboring home, so that convenience brought by everything interconnection is fully utilized, and a most stable solution to the safety problem is realized. For another example, the positioning and tracking application program module 13 in the server 1 can be set, and the positioning information of the portable positioning and tracking wireless module 7 is forwarded to the intelligent home program module 14, so that when the user arrives at a certain electronic bus stop board near home when coming home, the functions of home air conditioning and the like are started, and more applications are created.

This embodiment may further track the target object by the handheld device when further tracking of the target object is required. For example, when the target object is lost, the target object needs to be searched, the ID number of the wireless module on the target object to be searched is input to the handheld device, and the possible area of the target object is searched further. When the handheld device searches the signal sent by the wireless module, the handheld device sends out an acousto-optic prompt to guide the search of the target object, so that a good effect can be achieved.

Various applications in the system have a common server 1 for management, different applications can open data and accept requests of other sides, and the server 1 can forward data for both sides only after both sides authorize the server 1. Optionally, all data packets are encrypted and sent out, decrypted after receipt, and the data conforms to the agreed format and verification rules before being processed.
