Design and Implementation of a 780MHz Wireless Sensor Network for Electric Vehicle Management System

A 780MHz wireless sensor network applied for Electric Vehicle Management System is designed and implemented in this paper, which meets the requirements of RFID 800 MHz / 900 MHz band. This project has less interference, good anti-multipath attenuation effect, longer transmission distance and stronger diffraction ability. Compared with 2.4 GHz sensor network on the market, it consumes less energy, and it is more environmentally friendly and energy saving at the same transmission distance. In addition, the system reduces the probability of interference and destruction in the same frequency band, reduces the risk of theft of electric vehicles, and will become the mainstream scheme of the future Electric Vehicle Management System. The transmission distance of the 780MHz wireless sensor network designed in this paper is more than 1km in the urban area. After applied to the Electric Vehicle Management System in the residential area, it shows the characteristics of long transmission distance and strong anti-interference.
