Design Of Battery Auxiliary Measurement And Control System Based On Open Source Platform

The battery is an important component of the DC system of power plants and substations,and it is the power reserve after the entire station loses power.The battery compartment is a device room dedicated to providing a working environment for batterys in substation.The main task of the research is to design a measurement and control system for battery auxiliary equipment based on the DC system.The project will realize data acquisition of digital sensors such as temperature and humidity sensors,as well as control of auxiliary devices such as exhaust fans and heating grids in the battery room,by measurement and control program developed on the open source hardware RaspberryPi using Python.Meanwhile,using the open source WEB framework Django to complete an auxiliary measurement and control platform with functions such as data receiving and display,email alert push,and auxiliary device operation and delivery.The main work is as follows:1.Based on bus protocol such as 1-Wire,I2 C,UART supported by RaspberryPi,combined with the corresponding digital sensor technology,the measurement of battery temperature,ambient temperature and humidity and hydrogen content is realized;2.Realize the self-holding loop switch control feature of the ventilation motor and heating grid through the GPIO interface of RaspberryPi.At the same time,based on LIRC technology,realize the basic control of the dehumidification device and air conditioner installed later,and realize the control of indoor auxiliary equipment for battery;3.Based on WEB framework Django,database SQLite,front-end framework LayUI,chart tool Echarts and other open source softwares,the battery auxiliary measurement and control platform is developed,to achieve data reception,email push,auxiliary equipment operation and other functions.Different from the traditional method of constructing measurement and control system using configuration tools in the power station,the whole scheme is based onopen source software and hardware technologies.And coding is implemented on the open source platform framework to realize the basic measurement and control functions.Communication between data collection terminals and the platform uses HTTP interface to achieve.In addition to the control of non-intelligent devices in the power station,this topic proposes the use of open source hardware to drive the infrared transmitting device to control the infrared devices such as air conditioners,which can realize the automatic control of some auxiliary devices in the station at a lower cost.
