By providing the adapter board 140, the circuit of the adapter board 140 is configured with a chip for protocol conversion, and converts the standard protocol used by the second functional module 130 into an RS485 bus protocol suitable for RS485 bus transmission. For example, when the second function module 130 corresponding to the RS232 communication protocol uploads data (such as device status information) to the centralized controller 110, the data of the RS232 communication protocol is converted into data of an RS485 bus protocol by the chip of the adapter board 140, and is uploaded to the centralized controller 110 through the RS485 bus. Similarly, when the centralized controller 110 issues data (such as control information) to the second functional modules 130, the adapter board 140 converts the data of the RS485 bus protocol into data using the RS232 communication protocol, and issues the data to the corresponding second functional modules 130. Therefore, the electronic stop board can be flexibly connected into various functional modules, the connection operation is simple, and the unified control of the centralized controller 110 is realized.

In one embodiment, referring to fig. 4, a switch board 140 may be disposed corresponding to all newly connected functional modules, so as to further facilitate the wiring of the newly connected functional modules of the electronic bus stop. It should be noted that, in practical applications, if a plurality of protocol conversion programs are burned into a chip of the interposer 140 and a plurality of corresponding communication interfaces are provided, the interposer 140 can be accessed to a plurality of functional modules.
Further, referring to fig. 5, a schematic structural diagram of the interposer 140 is provided, wherein the interposer 140 includes an MCU, an RS485 bus protocol interface module, and a corresponding standard protocol interface module; the MCU is in butt joint with the RS485 bus protocol interface module and the standard protocol interface module, the RS485 bus protocol interface module is also in butt joint with the first end of the adapter plate 140, and the standard protocol interface module is also in butt joint with the second end of the adapter plate 140.
When the functional module needs to upload data to the centralized controller 110, the MCU of the adapter board 140 accesses the data uploaded by the corresponding functional module through the standard protocol interface module, further performs communication protocol conversion on the data through the MCU to obtain data of the RS485 bus protocol, and uploads the data to the centralized controller 110 by docking the RS485 bus through the RS485 bus protocol interface module. When the centralized controller 110 issues the control data to the corresponding functional module, the MCU of the adapter board 140 interfaces the RS485 bus to access the control data through the RS485 bus protocol interface module, converts the data of the RS485 bus protocol into the corresponding standard protocol data, and issues the data to the corresponding functional module through the standard protocol interface module.
Furthermore, the standard protocol interface module comprises an IO interface, an RS232 interface and/or a CAN interface. It CAN be understood that the IO interface, the RS232 interface, and the CAN interface are common interfaces for communication between devices, and by setting the interfaces, the communication compatibility between the corresponding functional module and the centralized controller 110 CAN be achieved.

However, in order to avoid the modification of the RS485 bus interface, an RS485 interface may be provided on the adapter board 140, and the function module is connected to the RS485 network through the adapter board 140.
On the other hand, the adapter board 140 further includes a coding switch, and the coding switch is used for defining address bits for accessing the functional modules, so as to distinguish each accessed functional module. By setting the coding switch, when the MCU of the adapter board 140 uploads or issues data, the data is issued to the corresponding functional module or is protocol-converted using the corresponding protocol conversion program and uploaded to the centralized controller 110 through the RS485 bus according to the address bit of the functional module.
In one embodiment, the electronic stop board further includes a voice playing module, and the voice playing module is connected to the centralized controller 110 for playing the arrival information in voice. Through setting up the voice broadcast module, when backstage (public transport management platform) issued line information or propaganda information to electronic stop borad centralized control ware 110, electronic stop borad centralized control ware 110 started this voice broadcast module, carries out voice broadcast to the vehicle information or the propaganda information that are about to arrive at the station.
In one implementation, the electronic station board further includes a ZigBee module, and the ZigBee module is in signal connection with the centralized controller 110 and is used for transmitting station-to-station information of adjacent stations. It can be understood that the electronic stop board generally corresponds to the bus stop, and two adjacent bus stops are generally within 3000 meters, use zigBee module can realize the electronic stop board communication between two adjacent bus stops. The bus stop system corresponds to the front bus stop and the rear bus stop, the running position condition of the current bus can be obtained by receiving the arrival information of the rear bus stop, so that passengers can know the current position condition of the bus in real time, and the riding experience is optimized. For example, when a certain bus arrives at a next stop, the corresponding electronic stop board publishes the arrival information on the electronic stop board screen, and further sends the information to the electronic stop board of the previous bus stop, and after the electronic stop board receives the information, "XX is still a stop away from the current stop" can be displayed on the display screen of the electronic stop board. Furthermore, the arrival information jumps among the stations through the ZigBee module, so that the electronic station boards can broadcast the position information of each bus in real time. It can be understood that, in practical use, reporting of the vehicle position information by using GSM, 4G network, etc. may be relatively accurate, but the network is relatively unstable and the cost is relatively high. Therefore, the embodiment of the application adopts ZigBee to transmit the station reporting information, so that the cost can be further saved.
