Research of frequency signal transmission of mine-used sensor
Tang Chao-ming · Gong-kuang zidonghua · 2013
In view of problem that monitoring and control system has error alarm and error power off due to frequency signal transmission mode of mine-used analog sensor is interfered by outer interference,the paper analyzed transmission performance and interference performance of frequency signal,proposed anti-interference measures such as differential transmission,sine-wave transmission,current transmission,bus transmission and reducing transmission frequency,and indicated CAN bus with multi-host would be development trend of signal transmission mode of mine-used sensor.
