摘　　要：针对智能配电网监控系统的特点,结合GPRS远程通信技术,采用ARM7处理器LPC1768、GPRS模块MC37i和24位高精度A/D采集芯片ADS1278,设计了高精度的配电网实时监控终端,解决了传统配电网监控终端传输距离短、测量精度不高、保护动作响应缓慢、实时性差等问题。在讨论了整体设计方案的基础上,介绍了软、硬件模块的设计方法,实现了实时遥测、遥信、遥控和快速故障保护等功能。测试结果表明,该装置测量精度高、通信距离远、数据传输稳定可靠、故障保护响应迅速、实时性强。According to the characteristics of intelligent power distribution network monitoring system, a high precision distribution network real-time monitoring terminal was designed. Combining with GPRS remote communication technology, ARM7 processor LPC1768, GPRS module MC37i, 24 bits high precision acquisition chip ADS1278 were used in the design. The problems of traditional power distribution network monitoring terminal, such as short transmission distance, low measurement accuracy, slow protection response and poor real-time were solved. On the basis of discussing the overall design of the system, the hardware and software design methods were shown. The functions of remote metering, remote communication, remote control and fast fault protection were realized in the design. The test results show that the device has high data measurement accuracy, long transmission distance, stable and reliable data transmission, fast protection response and good real-time.
