基于无线传输的电能质量监测系统

摘要

According to the actual situation of Hi⁃Tech Industrial Park of Dongguan,a power quality real⁃time monitoring system based on wireless sensor network is proposed. The structure of ARM plus DSP is used in the system to sample,analyze and process the electric signal on site. The high reliable ZigBee CC2530 module is used to realize the wireless communication between DSP and ARM,and complete the data transmission. The design of radio frequency circuit and the antenna is introduced emphatically. Electromagnetic compatibility and interference protection measure are analyzed. The RF performances of the circuit were tested with SmartRF Studio 7. The test results show that the system can satisfy the requirements of the real⁃time power quality monitoring of the precision instruments and equipments in automation production lines in the industrial park.%　　针对东莞高科技工业园的实际情况，提出了一种基于无线传感网络的电能质量实时监测系统。系统采用 DSP加 ARM 结构完成对现场电信号的采集、分析和处理，通过高可靠性 ZigBee CC2530模块实现 DSP 与 ARM 间的无线通信，完成数据的传输。重点介绍了射频电路及天线的设计，分析了电磁兼容及抗干扰措施，采用 SmartRF Studio 7验证电路的 RF性能，测试结果表明该系统能满足工业园中自动化生产线的精密仪器、设备的电能质量的实时监测的要求。
