Abstract

The invention discloses a wireless bus integrated information system which is composed of a bus wireless receiving and transmitting system and a bus station wireless receiving and transmitting system. According to the complete set of the wireless bus integrated information system, the low-cost 2.4GHz radio frequency technology and a 32-digit ARM microcontroller are combined to construct a city bus communication network. Short-distance communication between a bus and a bus station is achieved through the bus wireless receiving and transmitting system installed on the top of the bus, and bus station information is transmitted among bus stations through the bus station wireless receiving and transmitting system. Once a passenger presses a stop calling button, a nearest bus within the range will receive a calling signal, and a driver is reminded through an acousto-optic message. When the bus enters the bus station, the bus station can remind passengers of the arriving of the bus, and the bus station where the bus enters is displayed in real time. According to the wireless bus integrated information system, the driver can be immediately reminded of the fact that whether a passenger needs to get on the bus at a specific bus station in a wireless mode, unnecessary stopping of the bus is reduced, energy consumption is effectively reduced, and traffic pressure is relieved.
