with rapid development of the mobile telecommunications industry, numerous Power Equipment and Environment Monitoring System (PEEM) related products have emerged in recent years. These products provide convenient remote maintenance. However, most of the existing systems remain in the phase of collecting data, which is not very useful for further analysis to improve maintenance operations. In this paper, we introduce a PEEM-based online battery monitoring and maintenance platform called Blue Monitor system. By maintaining communication power supply system in the mobile base station, Blue Monitor can reduce fossil-fuel power generator usages, decrease operational difficulty, enable unattended monitoring service and extend battery life. It will significantly boost energy savings and financial benefits.
