Embodiment example
[0050] An on-line monitoring device 22 for buried pipeline leakage is designed. The strip waveguide rod 7 is made of 316L stainless steel, with a thickness of 1 mm, a width of 20 mm, and a length of 400 mm. The narrow piezoelectric chip 6 is made of 2-2 composite material, with a thickness of 1 mm, a width of 1 mm, and a length of 18 mm. Shell 10, clip one 9 and clip two 18 select polytetrafluoroethylene. Purchase commercially available battery 2, ultrasonic signal transmitting / receiving module, ADC sampling module, microprocessor and 4G module, and the signal conditioning module adopts an amplification and filtering circuit. An ultrasonic signal transmitting / receiving module, an ADC sampling module, a microprocessor, a 4G module, and an amplification and filtering circuit are integrated on the PCB circuit board 15 to form an on-line monitoring system composed of two on-line monitoring devices.
[0051] Two on-line monitoring devices are inserted into a bucket filled with soi...
