The Construction of Planning and Design System of Intelligent Connected Vehicle Test Site

The rapid growth of the number of motor vehicles in China has led to the increasingly sharp contradiction between parking spaces and vehicles in the test field. The traditional test field adopts wired communication, which leads to chaotic wiring and high design cost; In order to improve the utilization rate of parking space, improve the management level of the test site, and realize the remote control and management of the test site. Based on the Internet of Things technology, ZigBee and GPRS wireless communication networks are built, and the planning and design(PAD) system of intelligent testing ground is constructed. The intelligent test site management system based on the Internet of Things is designed. The terminal node HC-SR04 ultrasonic sensor collects parking space information in real time. The monitoring center and mobile phone client are developed to realize the remote control and management function of the test site. Through the communication experiment between nodes, the effective communication distance of the system is obtained by measuring the packet error rate of PER and the RSSI signal strength. The full simulation of the system verifies that the stability of the PAD system of the intelligent networked vehicle test site is good, and the intelligent management of the test site can be realized.
