摘要

测量电流是电气工程的基础。无线电流传感系统不需要将传感器插入电路，因此很有吸引力。本文介绍了采用最新推出的ZigBee无线协议实现该系统的方法和性能。该系统使用Rogowski线圈作为传感器，以及包含积分器、微控制器和ZigBee发送模块的发送单元。接收器有一个进一步的ZigBee模块，和一个进一步的微控制器驱动液晶显示器给出电流读出。测试表明，该系统工作正常，线性误差小于0.04 a，电池寿命可达8个月

Applications of Zigbee Wireless Technology for Industrial Instrumentation

Measuring current is fundamental to electrical engineering. Wireless current sensing systems, which do not involve the insertion of a sensor into a circuit, are attractive. This paper describes the implementation and performance of such a system using the recently introduced ZigBee wireless protocol. The system uses a Rogowski coil as the sensor, and a transmitter unit incorporating an integrator, microcontroller and ZigBee transmitter module. The receiver has a further ZigBee module, and a further microcontroller driving a liquid crystal display giving a current readout. Testing shows that the system works, with a linearity error of less than 0.04 A and a potential battery lifetime of eight months
