| 摘 要： | 针对交直流电源线路中电流的实时监控问题，设计了一种基于霍尔电流传感器的电源监控系统。在该系统中，电流传感器CSNE151—100基于霍尔磁补偿原理，将被测电流转换为具有线性关系的电压信号。系统中的数字信号处理器（ DSP）采集传感器的测量值并通过控制开关实现对电源的过流保护。在实验室对系统进行了测试，实验结果表明：该电源监控系统具有响应速度快、测量精度高的优点。该系统已应用到工程实践中，工作稳定可靠，具有很好的实用价值。

| Abstract: | Aiming at current real-time monitoring problem in alternating and direct current power circuit,a power monitoring system based on Hall current sensor is designed. Based on Hall compensation principle,current sensor CSNE151—100 in system converts measured current to linear voltage signal. Digital signal processor( DSP)in system collects measured value from current sensor and achieve overcurrent protection of power by controlling switch. The system is tested in labs,experimental results show that the designed power monitoring system has fast response speed and high measurement precision. It has been applied in engineering practice,and works reliably and stably and has good practical value. |
