Abstract: The primary data collection success rate of acquisition terminals at State Grid Jiusan Power Supply Company is only 96.23%. The daily workload for manual data supplementation and fault elimination is heavy, time-consuming and inefficient. Through analysis of contributing factors, terminal power supply failures and weak GPRS signals were identified as the main factors affecting the primary collection success rate. Testing demonstrated that implementing dual power supplies and signal amplifiers can effectively address the low primary collection success rate of acquisition terminals.
