| Summary: | The paper introduced composition and working mechanism of driving circuit and echo processing circuit of mine-used intrinsic safety ultrasonic ranging circuit system. By analyzing output voltage waveform, it calculated the maximum energy storage of each energy storage element in ranging circuit system. The experimental results show that the largest energy storage of each energy storage element is less than minimum ignition energy in ranging circuit system, which reaches stipulated intrinsic safety request of national standards. |
