Design And Implementation Of Multi-Function Environment Monitoring System Based On STM32

With the development of science and technology,people are increasingly demanding the collection and monitoring of environmental data.Video sensors,smoke alarms,temperature and humidity transmitters and all kinds of environmental monitoring systems are widely used in production and people's life.For the places with high environmental requirements for all kinds of electronic equipment,such as communication machine rooms,substations and large factories,it is necessary to monitor the operation and environment of the field in an all-round way.An environmental monitoring system that integrates all kinds of sensors in the same system is essential.However,some environmental monitoring points such as substations,communication base stations and other places are far away from the monitoring center and are remotely located.It is necessary to ensure the safe and stable operation of the equipment through remote monitoring.Under this background,this paper designs and implements a monitoring environment for monitoring sites where monitoring sites are relatively dispersed and inconvenient or where wiring costs are high,as well as special monitoring occasions that require medium and short-range wireless transmission and the need to acquire satellite positioning information.A multi-functional environmental monitoring system based on STM32 microprocessors.The monitoring system is designed with the STM32F107 microprocessor as the core.It is composed of three parts: monitoring host,sensing control part,and wireless transmission part.It integrates ARM embedded technology,Modbus,GPS satellite positioning,wireless communication,watchdog and other technologies..In addition to supporting real-time acquisition of conventional environmental monitoring data,it can also collect GPS location information of the system's location and the system's own energy consumption,and it also has data remote wireless transmission capabilities.The paper first elaborated on the meaning,function,development process and research status of multi-functional environmental monitoring systems,and introduced several models,advantages and disadvantages of environmental monitoring systems.Then,by analyzing the deficiencies of the existing system functions,the system monitoring needs of the environmental monitoring system are analyzed to determine the overall design and technical measures.The STM32F107 microprocessor is used as the core of the system,based on the Modbus fusion sensing control part,and the wireless data transmission.The radio realizes remote wireless data transmission,and then gives the system's detailed hardware design and software design.Finally,through the system's stand-alone operation test,remote data transmission test and analysis,it is proved that the system can realize real-time monitoring,control and remote wireless data transmission in the field under unmanned conditions,with good stability,and improved environmental monitoring.Efficiency has ensured the safe and stable operation of the monitoring point equipment and achieved the desired results.
