Smart bus electronic board is an indispensable public facility of bus stations in smart cities. With the construction of a smart city, light boxes of LED electronic ads, median strips, bus stations, smart bus electronic boards, smart cities, bus broadcasting systems, etc., are all important signs of a smart city. Zhejiang Jinhua Jindong District, Wucheng District, Yiwu, Pujiang, Pan 'an, Wuyi, Dongyang, Yongkang, Hangzhou, etc. gradually integrated the bus automatic broadcasting system into the bus electronic board through the Internet of Things, which facilitated the travel of passengers. In particular, the Yiwu bus electronic board facilitates the travel of domestic and foreign merchants, the Yiwu International Trade City, and local manufacturers and businesses, helping the majority of merchants and foreigners to save the travel cost.

Intelligent public transportation scheduling system is the use of advanced technology to dynamically obtain real-time public transportation information, and achieve real-time monitoring and scheduling of bus electronic board, electronic board prices, and simulated electronic boards. This is a new mode of bus scheduling. Predicting the running time between bus stations is the most important task of intelligent urban public transportation scheduling. The prediction theory, model, and method of time are studied, which aims to lay the foundation for promoting the rapid development of China’s intelligent bus system.
With the continuous development of the transportation industry, buses have become indispensable public transportation in the cities. The accuracy of bus station information and the broadcasting system in the bus are very important to passengers. The emergence of smart buses has solved these problems. The paper analyzes the research status at home and abroad and studies the core technology of the intelligent bus system. The designed intelligent bus system consists of three sub-modules: the on-board terminal, the monitoring central server, and the electronic bus board. The GPS module on the terminal sends the received satellite information to the STM32 master control chip. The STM32 master control chip sends the received GPS satellite information to the GPRS module after filtering out the latitude, longitude, time, and other information. The GPRS module sends the latitude, longitude, time, and information to the monitoring center through the base station. The automatic reporting station adopts the identification method of concentric circles. The position of bus electronic board is the center of the circle, and the radius is 20 meters.
When the bus is close to this radius, the on-board terminal gets the longitude and latitude of the bus and analyzes the distance between the bus and the station. When the distance between the bus and the station sign reaches 20 meters, it reports to the station through the voice module and the LCD module. At the same time, the on-board terminal sends the corresponding information to the electronic bus board. The electronic bus board is divided into a GPRS receiving module, a main control chip module, and an LCD display module, which can receive the data sent by the on-board terminal and report the station in advance. This project uses GPS positioning terminals to obtain bus status information as well as latitude, longitude, and time, transmits it to the monitoring central server and the electronic bus board through the GPRS network, and prompts arrival information.
