摘　　要：介绍了基于单片机的10 kV恒流充电电源监控系统设计。系统采用STC12C5410AD单片机作为控制的核心,利用AT89C2051单片机采集按键信息,通过采样电路获取充电过程中的电压、电流信息,然后在STC12C5410AD单片机的控制下,利用JHD12864F液晶显示器对充电参数及可能出现的故障进行显示,实现了对充电过程的数字化控制。鉴于系统工作在高压环境下,为提高系统可靠性、抗干扰能力以及充电的精度,在硬件设计和软件设计方面对系统进行了优化。经试验测试,该系统具有可靠性好,抗干扰能力强,精度高的优点。A monitoring system of 10kV constant current charging power supply based on single chip microcomputer is in- troduced. The system used STC12C5410AD SCM as the core, adopted AT89C2051 SCM to detect key-press, acquired voltage and current by corresponding sampling circuit, displayed parameter of charging and possible troubles by using JHD12864F un- der the control of STC12C5410AD SCM, and realized digital control of charging process. As the system working in high voltage condition, the system is optimized in hardware and software to improve the reliability of the system. The experimental results show that the system can work steadily with high precision, and has a broad application foreground.
