Abstract

The invention relates to a tunnel surrounding rock deformation automatic monitoring and early warning system which is characterized in that: a sensor unit (1) sends acquired data to an MCU module (2) after digital processing, the MCU module (2) carries out a preliminary treatment on the data and sends the data to a computer software unit (5) through an RS 485 data communication module (3), a power supply module (4) supplies power for the sensor unit (1), the MCU module (2) and the RS 485 data communication module (3), after data processing, the computer software unit (5) can send an AT instruction to an GPRS module (6) when is in danger, and the GPRS module (6) receives the instruction and sends early warning information to a preset mobile phone (7) to realize an automatic early warning function. Technical personnel such an expert, an engineer and the like are facilitated to carry out data analysis, and original data is provided for discovering a roadway deformation rule. In the invention, a database and figure analysis software can be arranged to connect with the computer software unit, and acquired analysis data can be automatically stored into a database and image analysis software of a computer. The system has the characteristics of strong multi-site capability, a long data transmission distance, simple operation, a small volume of a single monitoring station and a light weight, and is especially suitable or deformation monitoring of various mine tunnel engineering.

Description

technical field [0001] The invention relates to an automatic monitoring and early warning system for surrounding rock deformation of a roadway. Background technique [0002] The problem of roadway deformation is becoming more and more serious, especially the large deformation of the roadway directly affects the safety of mining production and economic benefits, and seriously endangers personal safety. [0003] The current roadway deformation monitoring technology still uses common methods, such as convergence meter measurement, tape measurement, manual laser measurement, etc. These monitoring methods are not only time-consuming, but also require a lot of money and manpower, and they cannot fundamentally solve the problem of real-time continuous monitoring. And achieve the purpose of early warning, especially the purpose of automatic transmission and long-distance communication cannot be realized. Contents of the invention [0004] In order to overcome the defects of the c...
