The Research Of Networked Status Monitoring And Fault Alarm System Of Mine Hoist

Mine hoist is an important tool for transportation in production of coal-mine, the safety moving of the mine hoist influences the daily production of the coal mining enterprises and life safety of the staff in coalmine. The productivity of the modern mine hoist is more and more high, mechanical construction is becoming complicated, the interrelation and coupling among different parts in equipment has also became wired, if one component has broken down, it will cause an interruption of the entire production process. The traditional methods of mine hoist testing exist out of repair and excess repair. With the development of test technology,computer technology and communication technology, it shows a realistic magnificence for developing a set of state monitoring and warning system that can monitor the operating status of mine hoist and make data communications.According to its severe working condition, mine hoist has high breakdown rate and all kinds of malfunctions. The common problems which happen in the motor,speed reducer,main spindle,braking system and other parts of the mine hoist will be studied in the project. By analysis of the fault mode,fault characteristic and fault harm, Based on the actual production situation of the coal mining enterprises and the stipulation of the actual running parameters of the mine hoist, The state monitoring parameters and its test method are ascertained.Based on the analysis of the networking models used in the networked status monitoring system, we adopt the C/S and B/S model. The C/S model has such advantages as rapid transmission speed and high safety, and the B/S model has its merits of easy connection with the database,allowing clients and servers frequent data exchange and without client software. Based on signal feature of system monitoring and characteristics of Network, hardware design scheme of the system is determined. This article designs software based on the models of C/S and B/S. The C/S model software which uses TCP/IP protocol to communicate, will mainly accomplish those functions as hoist parameters measurement,data communication,breakdown judgment,vibration analysis,fault storage and database management. the B/S model software will mainly accomplish user management,parameter setting,fault management and so on. In case of different user, the C/S model software includes three parts: hoist house software,server real-time monitoring software and client software. According to function, three parts software adopt different developing platform, hoist house software is written in Labview8.5, server real-time monitoring software and client software are programmed in VC++6.0.In this project, I conduct some special experiments including static characteristic experiments of hoist house system and communications experiments of the whole system. Test results show that: the system have good stability,good static characters and small test error, and the data communications of the whole system is stability and error-free .So the system has a high application value.
