Abstract

Disclosed are a coal mine roadway strain data acquisition method and device based on a three-level wake-up mechanism. The three-level wake-up mechanism is characterized in that timing data are acquired by an adaptive RTC (real time clock) timer wake-up method, RTC timing acquisition time is adaptively adjusted according to acquired roadway strain data fluctuation situations, so that the working frequency of a CPU (central processing unit) can be reduced when coal mine roadway strain and mutant data are acquired in an undistorted manner, overall power consumption is reduced, storage efficiency is improved, real-time data can be acquired by a patroller under a coal mine by an acquisition key wake-up method, the acquired data are wirelessly transmitted by a worker through an infrared signal wake-up method, historical strain data of a roadway are more conveniently checked by the aid of a handheld terminal, power consumption of a data acquisition device is reduced by the three-level wake-up mechanism, and a patrol inspection mechanism under the coal mine is met.

Description

technical field

[0001] The patent of the present invention relates to a coal mine roadway strain data acquisition method and device based on a three-level wake-up mechanism, in particular to a data acquisition device, which belongs to the technical field of measurement, control and automation. Background technique

[0002] The strain data acquisition device is an automatic equipment capable of real-time data acquisition, automatic storage and recording, signal preprocessing, real-time display, real-time state analysis, automatic transmission and other functions in coal mine roadways.

[0003] At present, the strain data acquisition devices in coal mine roadways usually use batteries as power supply equipment, but the service life of batteries is limited, and it is difficult to replace batteries in industrial sites, so how to reduce system power consumption to prolong battery service life is very important.

[0004] With the development of wireless technology, wireless commun...
