Leading edge signal acquisition device for pipeline transportation system geologic hazard remote monitoring

The utility model discloses a leading edge signal acquisition device, which is applied to the geologic hazard remote monitoring of a pipeline transportation system. The leading edge signal acquisition device consists of a power supply, a central processor, an acquisition passage controller, an A/D converter, a photoelectric isolation relay unit, a serial port chip and a frequency module. The central processor is connected with the frequency module through the serial port chip. On one hand, the acquisition passage controller is connected with the central processor and on the other hand is connected with the photoelectric isolation relay unit. The central processor, the A/D converter and the acquisition passage controller change data through a public data passage. By using the leading edge signal acquisition device to do remote monitoring, hazard can be prevented or found and handled in time, emergency measures are taken, the safe control of the pipeline can be realized, the security of the pipeline is improved
