In order to improve the means of bus dispatch, improve the efficiency of bus operations, and implement a smart campus, the design of an intelligent bus positioning system, which is based on the Internet of Things, is studied. This paper first discusses the location awareness of IoT nodes and the location awareness of multi-source positioning to achieve intelligent perception of the environment. Then, the overall design of the intelligent bus system of IoT is carried out, and the design idea of the three-tier network hierarchy based on the perception layer, the network layer, and the application layer is given. The system uses RFID technology to track, locate, and monitor buses. The touch screens at bus stops can count the number of passengers waiting for each bus, and the electronic bus-stop boards can publish the arrival time of each bus and some other information. The Zigbee wireless network technology is used to achieve communication between the vehicle terminal, platform system, and dispatch monitoring center. Finally, the simulated annealing algorithm is used to achieve intelligent bus scheduling, improve the quality and efficiency of bus service to meet the travel needs of citizens. |
