Mine elevator comprehensive performance testing system based on virtual instrument

Mine elevators are large electromechanical equipment with integration of mechanical, electrical and hydraulic parts, bearing the task of carrying material, equipment and personnel between ground and below ground levels. The mine elevator is the spine of the underground mining industry. At present, a great deal of elevating equipment on active service in China has not yet reached its life expectancy, and considering the cost, they can not be replaced wholesale. With production on the rise, the demands on the safety and reliability of the elevator operation are increased. In order to guarantee a minimum economic input and achieve maximum output, performance parameters should be measured in time to achieve the goal of real-time control. Virtual Instrument technology is a computer-based instruments and measurement technique, which combines computer and instruments, relying on computer hardware and operating system to realize various instrument function through software. "Hardware replaced by software" is the essence of virtual instruments. This paper is directed at the shortcomings of current mine elevator testing, a modern testing system based on virtual instrument software Lab VIEW has been established, which completes elevator performance test in the "Coal Mine Safety Regulations". Various signal processing methods are conveniently applied during testing. Compared with a traditional system, the new system improves the accuracy of test results, test efficiency, eases labour intensity, has good scalability and openness, and will have great application value and development prospects.
