摘　　要：目前用电信息采集终端控制系统的功率消耗过大,采集时延过长,为解决上述问题,基于哈希函数设计了一种新的用电信息采集终端控制系统,分别针对系统的硬件和软件进行设计。硬件主要由信息采集器、脉冲器和处理器三部分组成,采用RTU78系列采集器,遵循RS232C标准扩大采集范围,采用GJI987脉冲器防止程序遗失,选用Cortex-M3系列的STM32F107内核处理器提高访问权限。通过哈希函数向数据网络发出请求,利用信息终端实现采集,完成软件工作。实验结果表明,基于哈希函数的用电信息采集终端控制系统能够有效降低系统功率消耗,减少采集时延。At present,the power consumption of the control system of the electricity information collection terminal is too large,and the collection time delay is too long.In order to solve the above problems,a new control system of electricity consumption information collection terminal is designed based on the Hash Function,which is designed for the hardware and software of the system.The hardware is mainly composed of three parts:information collector,pulser and processor.It adopts RTU78 series collector,follows RS232C standard to expand the acquisition range,uses GJI987 pulser to prevent program loss,and uses Cortex-M3 series STM32F107 core processor to increase access rights.Send a request to the data network through the Hash Function,use the information terminal to realize the collection,and complete the software work.The experimental results show that the power consumption information collection terminal control system based on the Hash Function can effectively reduce the power consumption of the system and reduce the collection delay.
