Research and Development of an Intelligent Temperature-Measuring System Based on 1-Wire Bus

Through the research on stratum freeze construction, and based on monitoring the application environment of long-distance stratum freezing in coal-mine construction, temperature monitoring method of 1-wire bus was proposed. According to the 1-wire bus technology and theory, the characteristic of time signaling conveyance was analyzed, the 1-wire bus drive circuit controlled by SCM was designed, and a new generation of intelligent monitor system was developed, which enables the 1-wire bus technology to support longer cable of temperature monitoring and meets the measurement to the stratum freezing of long distance.
