Adoption of Photoelectric Sensor in Automobile Electronic Detection

Abstract

The continuous improvement of auto-related electronic detection technology has become a new direction of the development of the automobile industry. First, the ZigBee technology is compared with other wireless communication technologies, and the advantages of ZigBee technology are analyzed. Then it is used in automobile electronic detection jointly with photoelectric sensor. The wireless sensor network (WSN) composed of photoelectric sensor is introduced into automobile electronic detection platform, and a set of information acquisition system for automobile electronic detection based on ZigBee technology is designed. In the hardware field, CC2520 chip is selected as the main data transmission chip according to the actual needs of the system. The ZigBee node with CC2520 and photoelectric sensor as the core architecture is mainly discussed. At the same time, the anti-interference design of the node is added, so that the node has the ability to collect information such as tire pressure, speed, acceleration, temperature, and humidity. In the software field, IAR Embedded Workbench is used to debug the program of ZigBee node based on CC2520+ photoelectric sensor, so as to establish coordination points and optimize network performance. During the experiment, it is necessary to build a WSN based on photoelectric sensor and ZigBee technology. ZigBee nodes have fast response speed, accurate data return, and improved transmission speed. The WSN based on photoelectric sensor +ZigBee technology can maintain good communication quality and low packet loss rate. After applying it to speed information collection, the results further verify the accuracy of data collection of WSN established in this study.
