Design on Operating Conditions Date Acquisition and Remote Transmission System for Electric Vehicle
In order to be informed of the electric car running state parameter in the monitoring center in real-time, this system based on ARM9 - S3C2440 as core chip for data collection and transmission, it completed the data acquisition of the electric car running state by CAN module and wireless transmission the data by GPRS module and AT instructions. This paper has described basic principle of this system, main hardware circuits, program flow charts and parts of the source program. Through the actual test, results show that the system has higher reliability, it realized understand motor speed, battery operating conditions and so on in remote monitor.
