基于物联网的高校大型仪器设备电源控制系统研究(一)

Internet of Things-based Research on the Control System of Power Sources for Large Instrument and Equipment in Universities( Part One)

基于物联网的电源控制系统研究开发是高校大型仪器设备共享平台建设的重要工作,电源控制系统可实现对大型仪器设备的实时、远程控制,不仅有利于实验室的用电安全,使实验室尽可能做到无人值守,而且有利于维护大型仪器设备,提高资源的有效配置和利用率,促进教学与科研水平的提升。研究针对没有PC控制的大型仪器设备,共享平台预约成功通过的用户可凭借管理员授权的IC卡,刷卡后即可使用相应的仪器设备,实现刷卡供电、刷卡断电。系统主要根据刷卡机、电源控制箱、触摸屏和短信服务四个控制功能和性能需求进行整体设计,该项研究基于Zig Bee、GSM和STM32技术进行电源控制系统的研制,系统由无线通信层和信息处理层组成,无线通信层由Zig Bee模块和GSM模块分别完成刷卡控制和短消息通知,信息处理层工作则由STM32模块完成。经后期测试,该系统实现了设计所要求的各项功能,且运行稳定,为我国高校大型仪器设备共享平台的前期建设提供了有益借鉴。

Research and development of power source control system on the basis of Internet of Things is an important task of construction of a platform which shares large instruments and equipment in universities. A power source con- trol system can realize the real-time and remote control of the large instruments and equipment, which can ensure the electrical safety in the lab to realize an unattended lab as soon as possible but also help maintain large instruments equipment, improve the effective resource configuration and elevate the teaching and scientific research level. The research is targeted at instruments and equipment with no PC control and the users who have passed appointment from sharing platform can use related equipment after successfully swiping their ID cards authorized by the administrator, thereby realizing card swiping-based power supply and cutoff. The overall design of the system is based on four control functions and performance needs, i. e. card swiping machine, power source control box, touch screen and shortmessage service. Based on ZigBee, GSM and STM32 technologies, the research and development of a power source control system are conducted and the system consists of a wireless communication layer and an information processing layer, with the wireless communication layer completing card swiping control and short message notification and the work of the information processing layer done by Module STM32. The later test shows that the system can realize all functions required by design and stable operation, providing useful reference for the preliminary construction of large instrument and equipment sharing platform at universities in china.
