Abstract

With the increasing requirements of communication system on the reliability and intelligence level of power supply, the defect identification of communication power supply terminal head has become an important topic to ensure the safe operation of the network. This paper proposes a defect diagnosis method of communication power supply terminal head based on tunnel magneto-resistance (TMR) technology and current-temperature coupling model. By utilizing the TMR sensor's highly sensitive monitoring capability of current change and combining the coupling relationship between current and temperature response, an intelligent diagnosis system suitable for embedded deployment is constructed. The system realizes early identification of defects, state assessment and remote warning, and is especially suitable for communication power supply scenarios with unattended, space-constrained and harsh environments. The performance comparison with traditional methods verifies the comprehensive advantages of this method in terms of response speed, accuracy and deployment convenience, and it has good engineering application prospects.
