Design of data collection device of mine-used explosion-proof trackless rubber-tyred locomotive

In view of problems of limited data collection and centralized collection mode of traditional explosion-proof trackless rubber-tyred locomotive, a data collection device of mine-used explosion-proof trackless rubber-tyred locomotive was designed. Automatic protection data requirements of related industrial standards were introduced, four kinds of data type such as temperature, liquid level, pressure and frequency which need to be collected by explosion-proof trackless rubber-tyred locomotive was proposed, selection of sensors used to collect the data and principle block diagrams of signal collection were given. The application result shows that the device can dynamically increase or decrease amount of transmitters and has stable performance and reliable application.
