The battery in the new energy system works in a wilderness environment, and its remote data monitoring is often realized based on wireless communication methods such as GPRS. This transmission method requires the establishment of a dedicated base station, which is costly. Beidou short message communication realizes data transmission through satellite, without the need to set up a base station. Based on the above situation, a battery monitoring system based on Beidou short message communication is designed. The system is composed of a monitoring terminal, a Beidou receiver, and a remote monitoring cloud platform. Aiming at the software and hardware requirements of data collection, data monitoring and Beidou short message communication, corresponding design ideas and implementation schemes are given. At the same time, considering the influence of the wilderness environment on satellite communication, a transmission error control method based on data backup is proposed to improve its transmission reliability. Finally, it is verified by actual tests that the system can effectively transmit monitoring data and locate the battery. Maintenance personnel can monitor the data in real time through the cloud platform, reducing the construction and maintenance costs of remote monitoring.
