Abstract:Aiming at the real-time environment state of vehicle battery voltage and working temperature, remote monitoring communication system platform is designed and built by using embedded micro-processing system combined with 4G communication technology and Wireless Local Area Network (WLAN). The client terminal of the system collects the data and realizes the short-range and long-distance data communication. The server of the system uses the PC of Linux system and the mobile phone of Android system to receive the data. In the course of the experiment, the whole system can monitor the voltage of battery pack and the operating temperature environment accurately and remotely, and the error of the data shows that the voltage is less than 1%. The whole system runs stably, the performance is reliable, which demonstrate the convenience for the management personnel to the spot understanding.
