With the development of information technology,intelligent hardware and Internet of things technology are gradually popularized,more and more intelligent devices are designed and manufactured and put into industrial application and daily life.The real-time remote wireless monitoring of intelligent equipment enables people not only to grasp the required information at any time,but also reduce the labor cost,and improve the operation efficiency of industrial production line.At present,the traditional water meter(mechanical type),which is mainly used for water flow measurement,is developing to the intelligent photoelectric water meter in most urban water network.The water department also establishes a remote meter reading system for use.However,most of the water meters on the market have a single function and few visualization contents,which can only display the accumulated flow in a period of time.In addition,the valve control of the pipe network is realized by various manual stop valves,which can only be output at a constant speed according to the needs of water,and can’t store and close water according to the needs of users within the specified time.After preliminary investigation and research,the work of leakage detection water metering device has applied for a number of intellectual property rights.Through the application of new technology and new mode,the management level of many water companies or departments can be improved,the production cost of water supply can be effectively reduced,the safety and sufficiency of urban water supply can be guaranteed,the living standard of residents can be improved through information technology,and the facilities can be promoted to build a smart city.We will promote the construction of the Internet of things on water,the development of ecological water,water informatization and water modernization.On this basis,according to the complex demand of flow measurement,a multi-functional intelligent flow measurement and control system based on STM32 single chip microcomputer is developed,data transmission and remote control in urban water network.Among them,the system uses the electromagnetic flow sensor(Hall sensor)to measure the flow rate and flow rate in real time.The sensor can meet the requirements of high-precision flow measurement,and the test error of the flow sensor calibrated by experiments is less than 2%;Electric valves are used to regulate flow and flow.Compared with the common solenoid valve,The flow sensor can realize remote feedback control.The single chip of the system adopts stm32fl03zet6 single chip and RTC(real-time clock)chip designed by ourselves to calculate the time of the system and display the time and date of the LCD screen.In addition,the WiFi module of the measurement and control system uses the epe8266 chip,It is used to connect the Internet of things and the Internet of things platform,conduct data analysis,remote monitoring and other operations on the Internet of things cloud platform,and visualize data information in the form of graphics on the terminal,such as water flow speed,temperature curve,water flow statistical histogram,etc.The market demand analysis,scheme design,hardware and software design and system debugging of multi-functional intelligent flow measurement and control system are completed.Compared with the general flow measurement and control system,the system not only realizes the real-time monitoring of flow information,but also innovatively realizes the closed-loop control of flow,constant speed quantitative output,appointment control,connection object network,graphic display and touch control.It can meet the complex needs of the current traffic measurement and control industry,with great market potential and broad application prospects.
