Embodiment Construction

[0028] see figure 1 In order to better understand the technical solution of the present invention, the inventors of the present invention will describe in detail below through specific embodiments in conjunction with the accompanying drawings:

[0029] At the practical site of the project, when the rammer hits the ground during the dynamic compaction construction, part of the kinetic energy is converted into a shock wave, which propagates outward in the form of a wave centered on the compaction point, and causes surface vibration. This vibration may become a vibration hazard under certain conditions. , affecting the safety of the cable duct.

[0030] During dynamic compaction, the rammer penetrates into the foundation with impact force, and the energy is transmitted outward through the bottom and side of the rammer in the form of elastic wave strain energy, and the energy is converted into body waves and surface waves and transmitted to the soil. Surface waves are divided int...

Abstract

The invention discloses a cable duct vibration monitoring system in the field of electric facility maintenance, which includes a monitoring node and a data collection intermediate station. The monitoring node includes a measuring single-chip microcomputer, an acceleration sensor, a first multi-channel controllable power supply, and a wireless transmission device. Both the acceleration sensor and the wireless sending device are connected to the measuring single-chip microcomputer, and the first multi-channel controllable power supply is respectively connected to the measuring single-chip microcomputer, the acceleration sensor and the wireless sending device; the data collection intermediate station Including: a collection single-chip microcomputer, a wireless receiving device, a GSM communication device and a second multi-channel controllable power supply, the wireless receiving device and the GSM communication device are all connected to the collection single-chip microcomputer, and the second multi-channel controllable power supply is respectively Connect the collection single-chip microcomputer, the wireless receiving device and the GSM communication device. The technical effect is that the vibration monitoring efficiency of the cable duct is improved, the safety of power supply is ensured, and the long-term monitoring of the cable duct is beneficial.

Description

technical field [0001] The invention relates to a cable duct vibration monitoring system in the field of electric facility maintenance. Background technique [0002] Cable duct is an important facility to ensure the normal operation of cable lines. With the construction of large-scale engineering projects such as municipal engineering, buildings, roads and bridges, the use of various types of strong vibration engineering machinery such as dynamic compactors and pile drivers has become increasingly frequent, which has caused certain harm to the cable ducts near the construction site. The strong vibration caused The pipeline is damaged, water seepage occurs, ground sewage seeps into the pipeline, severely corrodes the cable, and causes problems such as cable insulation deterioration. Through real-time vibration monitoring around the pipeline, the owner of the cable equipment can obtain relevant data information in a timely manner, so as to prevent the occurrence of sabotage i...
