NB-IoT Wireless Technology Realizes Bus Electronic Stop Sign

The bus electronic stop sign system uses the vehicle-mounted terminal to collect the real-time running position of the vehicle, transmits the perceived data to the cloud monitoring service platform in real-time through wireless communication for corresponding positioning and data collection of the bus line, and realizes instant communication with the electronic stop sign. Módulo SPI The precise positioning function of the onboard intelligent terminal equipment and the embedded software system can automatically measure the distance (number of stops) to each bus stop ahead and publish the calculation results to the bus electronic stop sign in real-time to provide public bus information services.

The background monitoring system carries out corresponding positioning and data collection on the vehicle information of the bus line (including inbound and outbound information, departure station, the terminal station, GPS real-time positioning information, etc.). The time, position, speed, and other parameters uploaded in the fixed timing and fixed distance acquisition mode can automatically measure and calculate the distance (number of stops) to the bus stops in front, realize the dynamic information monitoring and positioning tracking of the bus vehicles, and release the calculation results in real-time Go to the bus electronic stop sign. At the same time, the system regularly collects and monitors the voltage, current, and temperature data of station equipment and batteries to realize abnormal alarms and ensure the dynamic, real-time, accurate, and complete release of bus information.

The bus electronic stop sign has a built-in NB-IoT communication function and has electronic circuit signs, a static road network, and signs with transfer maps. The electronic stop sign can receive relevant information from the dispatch center. The main content displayed on the electronic stop sign is as follows:

Displays the number of all online cars, making it easy for passengers to understand the operating information.

Displays the distance from the next bus to the station and the predicted arrival time, so that passengers can prepare for the bus. Módulo CAN

Display road congestion information so that passengers can make reasonable choices.

Displays the emergency information issued by the dispatch center.

Displays the station setting and station spacing of the whole line.
