Steel spring and tension sensor based dangerous rock collapse detection device and steel spring and tension sensor based dangerous rock collapse detection method

Abstract

The invention discloses a steel spring and tension sensor based dangerous rock collapse detection device and a steel spring and tension sensor based dangerous rock collapse detection method. The steel spring and tension sensor based dangerous rock collapse detection device comprises a plurality of tension sensors, the two ends of each tension sensor are both fixedly installed with one end of each steel spring, the other end of each steel spring is fixedly connected with a foundation seat which is fixed in an underholing formed in one side of a crack of a dangerous rock, a wireless module is arranged on each tension sensor, the wireless modules are connected with a receiving main engine through wireless signals, and the receiving main engine is connected with a receiving terminal. The invention simultaneously and further discloses the detection method of the steel spring and tension sensor based dangerous rock collapse detection device. According to the steel spring and tension sensor based dangerous rock collapse detection device and the steel spring and tension sensor based dangerous rock collapse detection method, mechanical parameter variation of the dangerous rock is used for collapse trend monitoring, and a data wireless sensor network is achieved and established. The steel spring and tension sensor based dangerous rock collapse detection device and the steel spring and tension sensor based dangerous rock collapse detection method has the advantages of being high in precision, breakage-proof, strong in antijamming capacity, convenient in measuring and the like.

Description

[0001] technical field [0002] The invention relates to a detection device and method, in particular to a device and method for detecting dangerous rock mass collapse based on a steel spring and a tension sensor. Background technique [0003] The safety monitoring of dangerous rock mass has been studied for a long time, and there are many monitoring methods. The traditional method adopts the intuitive micrometer observation method, which is to directly measure the crack width change of dangerous rock mass with a micrometer. The measurement method is intuitive and simple. However, there are problems such as poor precision and inability to record. [0004] With the further development of science and technology, GPS and INSAR three-dimensional laser scanners have also been introduced into the safety detection of dangerous rock masses. Although the data collection is convenient, the accuracy still cannot meet the monitoring requirements, and the cost is expensive. In engineeri...

The measurement method is intuitive and simple. However, there are problems such as poor accuracy and inability to record

[0004] With the further development of science and technology, GPS and INSAR three-dimensional laser scanners have also been introduced into the safety detection of dangerous rock masses. Although the data collection is convenient, the accuracy still cannot meet the monitoring requirements, and the cost is expensive. In the engineering application, it can not play a very good role in monitoring and predicting the collapse of dangerous rock mass.
