Design And Realization Of Monitoring System Of Gasification Cracking Furnace Based On Single Chip Computer

This thesis takes the gasification and cracking furnace of Xinhuochuan Environmental Protection Technology Co.,Ltd.as the research object.According to the working principle of the product and the needs of users,combined with the related technologies of the Internet of Things,a monitoring system is designed.Gasification cracking furnace is a waste treatment equipment that applies pyrolysis gasification technology.It pyrolyzes waste at high temperature in an oxygen-limited environment and converts it into mixed combustible gas for secondary incineration.The final flue gas emission data is far lower than the national Pollutant emission standard value.In this thesis,a monitoring system is designed for the gasification and cracking furnace,which provides an intuitive and clear control interface for users to control the operation of the gasification and cracking furnace,and feedback the operation status of the equipment in real time,so as to further improve the waste treatment capacity of the gasification and cracking furnace for researchers,Provide data reference to lay a solid foundation for improving user experience and promoting product marketization.The thesis starts with the hardware circuit design first,with the single chip STM32F407 as the core processor.According to the working requirements of the gasification cracking furnace,the device is selected and the peripheral circuit is built.The functions to be realized mainly include control of ignition,liquefied gas intake,adjustment of oxygen intake,temperature collection in the furnace and monitoring interface display of the host computer.Design hardware peripheral circuits in modules according to functional requirements,and provide circuit-level solutions for the power supply problems of each module.The development of the software layer is mainly based on the STM32 firmware library,which realizes the two-way communication between the processor and the host computer:STM32 can not only receive the commands issued by the host computer and respond,effectively control the corresponding peripherals,but also upload the operating status of the device,which is displayed and stored by the host computer.The host computer provides a visual interface for the realization of human-computer interaction functions,including the Wei Lun Tong touch screen installed at the proximal end of the gasification and cracking furnace and the ONENET cloud platform using wireless communication technology.The near-end host computer only needs to monitor a single gasification and cracking furnace one-to-one,and the remote host computer ONENET cloud platform can add multiple devices to realize the centralized management of multiple gasification and cracking furnaces.The monitoring system designed in this thesis includes two parts: local monitoring and remote monitoring,and realizes the functions of controlling ignition,air intake,adjusting oxygen intake,temperature acquisition and human-computer interaction.The ignition and air intake functions include two forms of switch and delay switch.The oxygen intake is adjusted in the form of the percentage of fan speed,and the temperature collection range is 0 to 1300 degrees.Finally,the accuracy of part of the designed circuit is verified by the MULTISIM simulation software,and the overall function of the system is proved to be normal by the physical test.
