The Development of Portable Intrinsically Safe Recorder of Vibration Measurement Used in Coal Mine

Abstract

For now, It is impossible to carry out vibration monitoring in underground coal mine in china, mainly due to the fact that intrinsically safe recorder of vibration measurement used in coal mine hasn’t been developed, this paper advances and develops a kind of portable intrinsically safe recorder of vibration measurement used in coal mine(RVM), host computer of the RVM is developed based on embedded ARM10 and PC/104 technology, employing Windows CE service platform. The RVM is designed according to the request of GB3836.4-2000 standard, and has many characteristics, such as small size, portability, legerity, antistatic, built-in operation system having simple operation, high-speed data acquisition and mass storage. The RVM has already obtained the safety certificate of approval for mining products so that it can be used in underground coal mine, which solves the question of data acquisition used in equipment fault diagnosis research and can provide basic data for related research based on vibration, at the same time, through the analysis of these data provides the theory basis and foundation to improve the design and performance of mining equipment.
