摘要

介绍了 Analog Devices Inc.（ADI）公司新推出的电压、功率测量芯片 AD7756 的特点，以及利用该芯片设计的合肥光源的电网电压监视系统。该系统采用 RS485 总线接口，可同时监视 64 个节点。每个节点模块包含两个模数转换器、电压参考基准、温度传感器和相关的数字信号处理器。每个节点可现场设定电压波动报警阈值，也可实时电压波形采样，采样率达 14 kSa/s。电压监视在提供 RS485 总线接口的同时，也提供通用串行接口 RS232。相比其它设计方案，基于 AD7756 电网电压监视系统的设计具有成本低、精度高、实时性好、功耗小、可靠性高等特点。

Abstract

Features of a voltage/energy measuring IC AD7756 are introduced in this paper. By using this IC

we designed a voltage network monitoring system for HLS. With the bus interface of RS485

the system can monitor 64 sites simultaneously. Each site module includes 2 ADCs

a voltage reference

a temperature sensor and a relative DSP. It can set the voltage alarm threshold when working

and sample the voltage waveform in real time at the sampling rate as high as 14 kSa/s. Besides the bus interface of RS485

the common serial interface of RS232 is available too.
