Design Of Real-time Collection And Transmission System Of Basic Information Of Urban Pipe Network Water Body Based On RT-Threa

With the rapid development of urbanization in my country,the contradiction between urbanization development and urban ecological environment has become increasingly prominent,and cities are facing problems such as waterlogging,water pollution,and water shortage.In order to deal with such problems,the country is committed to building a smart water system that integrates multiple nodes such as detection,collection,transmission,analysis,and processing.This paper focuses on the analysis of the basic information monitoring requirements of urban pipe network water bodies,and divides the overall system design into terminal hardware design,terminal software design,and monitoring application program design.Real-time collection and transmission system of network water body basic information.The terminal hardware circuit is mainly composed of power supply circuit,STM32 minimum system circuit,Bluetooth interface circuit,RS485 communication circuit,4-20 m A communication circuit,network module peripheral circuit and other functional circuits.The embedded terminal system software is implemented based on the RT-Thread real-time operating system.The system tasks include modules such as sensor data collection,cloud server data interaction,and application program data interaction,and each task module is scheduled in sequence by the multi-thread mechanism of the operating system.The terminal monitoring application developed based on the Android system establishes a communication connection with the terminal Bluetooth.The software has functions such as real-time display of terminal system data,online configuration of terminal operating parameters,and local cache configuration parameters.Users can use the application to visually view the operating status of the terminal and improve the efficiency of terminal equipment debugging.After the system design is completed,it has passed various verification tests of professional water affairs laboratories.The results show that the embedded terminal,terminal monitoring application program and cloud server modules designed in this paper are working normally,the overall communication link is stable,the transmission data packets are complete,and the terminal The accuracy error of 4-20 m A signal acquisition is less than 0.03 m A,Device sleep power as low as 0.33 W,which meets the requirements of actual scenarios.
