Perform programming development. VisualBasic.Net. Net is a structural framework that enables the development of Web applications and provides convenience for real-time remote monitoring. System function module design The main function of the mine hoist remote monitoring and fault diagnosis system is to monitor the operation of the hoist in real time and process the data collected by the data collection system, analyze and obtain the type and cause of the hoist failure, and alarm Display processing to prevent malfunctions.
Functional block diagram of the software system, including remote monitoring, data processing and alarm display modules. Through the remote monitoring module, the operating parameters and curves of key parts of the hoist can be monitored in real time, and the running state of the hoist can be analyzed; when the hoist fails, the remote fault diagnosis system of the mine hoist reads the hoist by requesting the database of the server Fault diagnosis value, realize accident diagnosis alarm; data storage and print query function in the data processing module can achieve full data sharing with remote client users.
Remote client The remote monitoring system client of the mine hoist enters the remote monitoring system interface by entering the corresponding web page link in the browser. The client sends a login request to the Web server from the browser. The Web server responds to the user's request and authenticates the login information. After successful authentication, the server assigns permissions based on the client's login identity and automatically enters the monitoring interface, through different controls on the operation page. Realize remote monitoring and fault diagnosis of mine hoist.

Application: flow meter measurement
There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.
Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.
