The first vibration sensor is disposed on a high-pressure gas insulation switch flange. A high-pressure gas insulation switch is connected with a high-pressure GIS device. The first vibration sensor converts detected mechanical vibration signals to electrical signals. The second vibration sensor is disposed on a metal supporting member. The metal supporting member supports the high-pressure GIS device. The second vibration sensor converts detected mechanical vibration signals to electrical signals. The signal acquisition amplification module performs amplification and filtering processing on the electrical signals sent out by the first vibration sensor and the electrical signals sent out by the second vibration sensor so as to obtain digital signals. The transmission module transmits the digital signals obtained by the signal acquisition amplification module to the master control computer. The master control computer performs vibration monitoring on the high-pressure GIS device according to the digital signals transmitted by the transmission module.
