Function of electronic board: background
The electronic board of bus stops will adopt a new generation of application systems that combine global satellite positioning and navigation technology (GPS), advanced communication methods, geographic information system technology (GIS-T), advanced video transmission technology, and smart sensors. It can make full use of the arrival data based on GPS in the current bus intelligent dispatch management system and establish a bus arrival forecast system through technology. After the completion of the project, the system will cover most bus stops and release real-time arrival information on all buses, which can provide real-time and accurate bus arrival forecasts for waiting passengers. In addition, the project comes with functions such as multimedia video playback, real-time video surveillance, passengers’ suggestions, public information release services, etc.
Electronic board: installation plan
For buses that have installed the on-board GPS positioning system, the bus positioning data is released to the control center server through the wireless network based on the existing bus dispatching system data. The real-time arrival information of the buses is calculated, and the calculation results are sent to the electronic board equipped with wireless communication equipment. Then, the forecast and information are released on the LCD screen.
Electronic board: functions
Real-time bus arrival forecast: It can display bus arrival forecast information which includes route forecast and distance forecast.
Multimedia video information release: It can display time and date, weather forecasts, public transport government information, advertisements, etc.
Voice broadcast service: Bus position is broadcast through the TTS live voice broadcast system. The volume can be controlled backstage in real time. The timing period can be automatically adjusted.
Mobile intelligent monitoring: It can monitor passenger traffic, vehicles, and public security around bus stops in real time.
Automatic detection: Abnormalities of the electronic board can be automatically sent to the management center and the designated mobile phone.
Remote settings: time switch, floor light switch, low power consumption, maintenance rate, energy saving, environmental protection, and saving labor costs.
Vending function: Passengers can select and buy items through electronic boards. And the details of goods inside each new electronic board can be checked backstage in real time.
Shared umbrella: It is easy to borrow and return an umbrella with automatic identification.
Wireless charging: It is applicable to the latest wireless charging technology, providing free charging service.
Electronic board: devices
The electronic board as a whole includes six parts: the electronic board system, the information release system, the video surveillance system, the centralized control system, the centralized power supply system, and the safety control system.
The electronic board system includes an intelligent board management cabinet, LED cold light source, heat dissipation system, and a strong power safety management system.
The information release system uses a high-performance LCD industrial screen to display information.
Video surveillance system uses high-definition cameras, hard disk video recorders, and other equipment to monitor the security and passenger traffic of the platform.
The centralized control system uses high-configuration industrial personal computers to control the operation of the entire electronic board.
The centralized power supply system uses relays, switches, electricity meters, time switches, etc. to ensure stable and reliable power supply.
The safety control system monitors the working condition of the environment and equipment, gives illegal intrusion warnings, etc. through the alarm device.

Basic functions of the management workstation
1.It should receive data from the communication server at any time, showing the distance or time of buses to the stops.
2.The electronic map of the control center has the function of querying relevant data such as buses, routes, roads, etc.
3.The electronic map of the control center can display the current operating status of each route, such as operation, flameout, breakdown, etc. (GPS manufacturer can offer technical support).4.According to the distribution of buses, the dispatching room can judge the road conditions and send dispatching and control instructions to the driver.
5.It can prompt the starting and last departure time of the route to the electronic board. It can estimate the distance, and time from bus stations where the bus departs to another stop. Furthermore, it can publish road conditions, advertisements, etc.
