Abstract : This paper uses KingSCADA 6.5 software to design a monitoring system for mine ventilation fans. By using Advantech PCL813 and AI808 to communicate with the computer, the hardware design of the monitoring system is designed. The monitoring system composed of KingSCADA realizes real-time data acquisition and display, historical data query, over-temperature alarm, printing and other functions. The system has the following characteristics: intuitive and simple graphical interface, accurate and reliable data acquisition, and convenient operation. Keywords : industrial control configuration software; KingSCADA; mine ventilation fan; monitoring system 1. Introduction With the rapid development of computer technology and network communication technology, the application of computers in the field of industrial control is becoming more and more widespread. As the situation on the control site becomes more and more complex, it is required to use a monitoring system software with high safety and reliability and a user-friendly interface [1]. Currently, more and more people are using configuration software for control system design and development, and correspondingly, the demand for configuration software is also diversifying. Users of configuration software for industrial control system design and control can gain the following benefits: 1. Reduced development costs, especially for future control system upgrades and updates, shortening the development cycle and investment of control software; 2. Strong flexibility and scalability; 3. Provides a user-friendly human-machine interface; 4. Provides high reliability; 5. Strong adaptability to changing needs, with a strong mechanism for storing and managing control systems, facilitating system maintenance; 6. Helps reduce tedious and repetitive work, facilitates reuse and collaborative development, and improves labor productivity. With the continuous advancement of scientific management, the degree of equipment automation and operating efficiency are constantly improving. Therefore, the ability to promptly and accurately alarm and diagnose various faults or early abnormal states that occur during equipment operation is of great significance for preventing or eliminating faults and improving the reliability, safety, and effectiveness of equipment operation. The development and research of measurement and control system software based on configuration software meets the above requirements. It is not only highly reliable, easy to operate, and has good real-time performance, but also has an intuitive and generous human-machine interface. At the same time, the development cycle is short, and the system is easy for on-site maintenance personnel to modify, expand, and upgrade. In the monitoring system, domestic configuration software is used as the platform. The system is reliable and stable in performance. It can meet the needs of most engineering projects, and the price is only 1/8 to 1/3 of the foreign similar products, which reduces the engineering cost and has a high cost performance [2] . 2. Features of KingSCADA 6.5 version 1. User interface is friendly, with rich screen, comprehensive functions, simple operation, and easy to use; 2. It has strong versatility and can be applied to various control processes in the field of industrial control; 3. It has high real-time performance and often adopts real-time multi-task operating system or embedded real-time multi-task kernel, as well as interrupt mechanism; 4. It adopts screen grouping and website browsing method to make user operation faster and more convenient; 5. It provides system variables for displaying and controlling network status, which can be used to monitor and control system network status; 6. The system is safe, reliable, and stable in performance and can run for a long time. Design of Mine Ventilation Fan Monitoring System Based on KingSCADA 6.5 Full Text Reading
