Data Acquisition And Transmission Design Of Intelligent Well Cover Based On Internet Of Things

The damage or loss of manhole cover is a common problem in urban water management.When it is serious,it will damage personal safety and property.In order to solve the problem of location and repair of the stolen manhole cover in time,and the cover of the well cover can not be fixed and repaired in time after breakage or loss,the thesis monitor and manage the city's manhole cover in an efficient and intelligent way to solve security risks.It is based on the Internet of Things technology,the sensor data collection,wireless network transmission data,computer processing data and so on.(1)The thesis designs a intelligent well cover system based on Internet of things.The overall system uses WIFI wireless transmission technology and angle sensors to collect angle data.The angle collector uses STM32F103 microprocessor which is based on Cortex-M3 kernel as the main control chip to construct the hardware platform.The angle data is collected by the six-axis attitude sensor module and is passed to WIFI module composed by ESP8266 for wireless transmission.(2)The remote monitoring platform is developed under the PC's Windows environment.Its main task is to achieve a good human-computer interaction with the tool of Visual C++.The software can display the angle information of the module,and send out the alarm information when the module exceeds 30 degrees.(3)By building a test platform,the system realizes the collection and recording of the angle information of the well cover,and it can send out the alarm signal when the tilt angle of the system plate exceeds 30 degrees.The test results show that the design of the system is advanced in technology,accurate in judging the state of the well cover,and is safe and reliable by using solar energy.In addition,it has some practical value of engineering.
