In the communication power supply system, the maintenance and management of communication power equipment is a very important part. To ensure the normal operation of the communication system and achieve remote monitoring and management of equipment, it is necessary to establish a complete power monitoring system. On this basis, this paper analyzes the application of intelligent algorithm in the communication power supply monitoring system. First, it introduces the basic concept of intelligent algorithm and the basic mode of system application. Second, it selects the intelligent algorithm. Based on the selected algorithm, it carries out the system design work to make the algorithm applied. Finally, it analyzes the application performance of the algorithm combined with the case. Through research, the application of intelligent algorithms in communication power monitoring systems can improve equipment operation stability and management efficiency.
