Mine Hoist Fault Diagnosis System Based on configuration software

Abstract: the three-dimensional force control configuration software is used to develop the mine hoist fault diagnosis system. The human-computer monitoring is given to TORLON Pai processors to support the separation of graphical interface and process data processing. The built-in independent real-time historical database, powerful distributed alarm, event processing, etc. improve the efficiency of system development and make the fault detection of the system more timely and accurate, Thus, the mine hoist can run reliably and accurately. The results of debugging and operation show that the system is reliable and has high control accuracy, and can fully meet the requirements of field production and operation

key words: mine hoist; Fault diagnosis; Configuration software

1 introduction

mine hoist, as a typical mechanical and electrical equipment, occupies an important position in the whole integrated automation production and is called "the throat of the mine". Generally speaking, the main shaft hoist is responsible for lifting the useful minerals mined underground, and the auxiliary shaft hoist is responsible for lowering materials, lifting personnel and equipment. In view of the special working environment of coal mining enterprises, once the mine hoist breaks down, it will cause immeasurable economic losses and casualties. Therefore, this paper establishes a fault diagnosis system of mine hoist with configuration software according to the actual needs of coal mine

the research on fault diagnosis of hoist will greatly improve the safety and reliability of equipment operation. The intelligent fault diagnosis and prediction system of the hoist can obtain the real-time data of the current operation of the equipment, accumulate the historical trend data, analyze and process the data and signals, analyze and find the type, cause and degree of the equipment fault, save the fault data and recall the accident, so as to improve the economic performance of the equipment, avoid sudden accidents, reduce unnecessary losses, and contribute to the safety, efficiency and Provide strong support for economic operation. Therefore, the application of equipment fault diagnosis technology in coal mine is of great significance

2. Introduction to force control configuration software

Beijing Sanwei Force Control Technology Co., Ltd. is a high-tech enterprise specializing in the R & D and service of monitoring configuration software. Its core software products were founded in 1992. Driven by independent innovation, the company has gradually established its leading position in the domestic market

the force control configuration software is a special software for field production data acquisition and process control. Its biggest feature is that it can integrate the system in a flexible and diverse "configuration mode" rather than programming mode. It provides a good user development interface and a simple engineering implementation method. As long as its preset software modules are simply "configured", It can easily realize and complete the functions of the monitoring layer, shorten the system integration time of automation engineers, and greatly improve the integration efficiency

3. Diagnosis system design

the whole diagnosis system is divided into five functional modules: system management, real-time monitoring, printing query, alarm and fault diagnosis, as shown in Figure 1. It mainly realizes the monitoring functions of the production process conditions, safety braking system, shaft signal system, etc. of the hoisting system, and has the functions of event and fault diagnosis and alarm, hanging data display and report statistics of the interconnected platform Sinosteel and the first public logistics information freight platform in China. It can guide the driver to operate and repair, judge and handle faults, and plays an important role in improving the safety and reliability of the system and the operation efficiency of the hoist

Figure 1 Structure of monitoring system

when designing the picture, try to take into account the actual conditions such as striking and consistent with the operating habits, such as aramid and carbon, and the possibility of misoperation. The design of the main interface shall include the overall information of the whole system as far as possible to make it clear at a glance. Combined with the on-site process flow, the system mainly designs the following interfaces: system startup interface, operation interface, manual operation interface, process flow, historical curve interface, report system interface, etc

4 generation of trend curve and report

4.1 trend curve

the data collected by force control on site are stored, displayed and analyzed according to the real-time data and historical data after processing. In the force control tool group, in addition to displaying the data in the window screen and report, force control also provides various curve components with powerful functions to analyze and display the data

through these tools, you can analyze and compare the current real-time data and the stored historical data, capture the process state that occurs in a moment, enlarge the curve to analyze the process situation in detail, and compare the function relationship between the two process quantities. The force control analysis curve supports the distributed data recording system, allowing the analysis and display of various real-time and historical data of other network nodes under any network node. The analysis curve provides rich attribute methods and convenient user operation interfaces. General users can use various configuration interfaces provided by the curve to control the curve. Advanced users can use the attribute methods provided by the analysis curve to flexibly control the analysis curve, which has achieved more complex and flexible user applications. Force control provides two kinds of trend curves: real-time trend and historical trend. As shown in Figure 2:

4.2 expert report

expert report provides excel like spreadsheet functions and can realize more complex report formats. Its purpose is to provide a convenient, flexible and efficient report design system

expert report is mainly applicable to the field of industrial automation. It is the most ideal solution to solve the problems of chart, report display, input, print output, etc. in the actual development process. Using expert reports can greatly reduce the workload of report development, improve the human-computer interface of reports, and improve the configuration efficiency. The operation effect of this system is shown in Figure 3:

5 conclusion

combined with the real mine hoist experimental device, the mine hoist fault diagnosis system is developed. The system runs normally after debugging, and the temperature signal and vibration signal of the motor can be transmitted to the monitoring interface in real time, which meets the needs of improving the detection of many machines in the market we touch. The monitoring interface can also display the real-time curve, event record and alarm information of the monitoring signal, observe the operation of the hoist, and avoid some failures, effectively preventing safety accidents caused by hoist failures
