Abstract

The present invention relates to a vibration sensor tunnel on-line monitoring system based on wireless network transmission. The system comprises a monitoring system upper computer, at least four wireless vibration sensors and a mobile device terminal. The wireless vibration sensor is installed on the tunnel, and the monitoring system upper computer is connected with the wireless vibration sensor and the mobile device terminal; and the wireless vibration sensor records the vibration data of two directions of the tunnel in real time, the data is transmitted to the monitoring system upper computer through the wireless network, the monitoring system upper computer stores and displays the actual engineering data of the vibration signals, and the monitoring system upper computer makes out the real-time line chart of the vibration system according to the collection data, and a mobile terminal employs the wireless network to remotely access the monitoring system upper computer and reads the collected monitoring data. Compared to the prior art, the vibration sensor tunnel on-line monitoring system based on the wireless network transmission can couple the vibration signals of the two directions, actually reflect the vibration condition in the tunnel, and is fast in response time and low in resource occupancy rate, etc.

Description

technical field [0001] The invention relates to a vibration monitoring system, in particular to an online vibration sensor tunnel monitoring system based on wireless network transmission. Background technique [0002] The vibration signal of the underground tunnel is the most typical drastic change signal. During the operation of the subway, the operation of the train will generate huge vibration and noise interference. Cities such as Shanghai, Hangzhou, and Guangzhou belong to cities in saturated soft clay areas. Even if the soft soil foundation has been consolidated for a long time, it may have a certain degree of settlement after receiving the train running load continuously. The long-term train vibration will cause microstructure damage to the soft clay, which will further lead to the deformation of the subway axis and the settlement of the track foundation. Train operating load involves many factors, including train speed, track structure, train axle load, etc. Monito...
