Group prediction and group prevention crack detection device

Abstract

The invention relates to a group prediction and group prevention crack detection device, and the device comprises an alarm monitoring background, a plurality of alarm main units and a crack meter. Each alarm main unit comprises a remote wireless communication module, a short-distance wireless communication module and an acousto-optic alarm device. The bottom of the crack meter is provided with aninstallation rod, and a side surface is provided with an opening. A moving end is disposed at the opening, and is in telescoping connection with the crack meter. The crack meter includes a displacement monitoring module disposed inside the moving end, a housing, a short-distance wireless communication module, a GPS module, a data acquisition module and a first power module, wherein the short-distance wireless communication module, the GPS module, the data acquisition module and the first power module are disposed in the housing. The alarm main units and the crack meter are connected in a modeof short-distance wireless communication. The alarm main units and the alarm monitoring background are connected in a mode of remote wireless communication. The device provided by the invention is advantageous in that the device is portable, is easy to install, is wide in application range and achieves real-time positioning; not only ensures real-time monitoring and alarm, but also greatly reducesthe power consumption; prolongs the service life of monitoring equipment, and reduces the operation and maintenance cost of a monitoring system.

Description

technical field [0001] The invention relates to the technical field of displacement measurement, and more specifically, to a group measurement group anti-crack detection device. Background technique [0002] The crack meter mainly measures the opening and closing degree of cracks or expansion joints in concrete, rock, soil and structures, and is also suitable for displacement measurement of various structures. It is mainly used in railways, highways, bridges and civil buildings, hydropower and water conservancy projects, petrochemical, Environmental monitoring, industrial hotspots, tunnels, subways, geological disaster monitoring, etc. In the monitoring of geological disasters, it is often necessary to monitor the movement status and movement trend of the surface of geological bodies. When the development trend exceeds the estimated safety range, the possibility of geological disasters will greatly increase. In this case, Effective real-time monitoring and timely early warn...

AI Technical Summary

Problems solved by technology

1. The crack meter is mainly aimed at the field of civil structure monitoring; 2. The crack meter needs 24 hours of uninterrupted data collection, and the equipment itself consumes a lot of power. Although there is technology for solar charging, it is not suitable for monitoring sites in some areas. Due to vegetation and other reasons, solar charging equipment cannot be used due to objective environmental conditions, and the maintenance cost of the power supply system of the equipment accounts for the vast majority of the later operation and maintenance costs of the entire system; 3. The construction and installation of the crack gauge is complicated, not portable, and not It is suitable for group measurement and group prevention and emergency monitoring; 4. The crack meter does not have the positioning function, and emergency monitoring and other sites cannot timely return the location data of the monitoring site; 5. The crack meter adopts the centralized management mode of the control center, and the control center needs to arrange it all year round. Personnel on duty, high labor costs, poor real-time interaction
