Abstract

The invention discloses an intelligent roof displacement sensor and a meter calibration method thereof. The intelligent roof displacement sensor comprises a singlechip, a communication module RSM3485, an analog-to-digital (AD) conversion module, a liquid crystal display module, two resistance transformation type abscission layer sensors, a wireless data transmission module and an intelligent data collector, wherein a pin RXD of the wireless data transmission module and a pin RXD of the communication module RSM3485 are simultaneously connected to a pin TXD of the singlechip; a pin TXD of the communication module RSM3485 is connected to a pin RXD of the singlechip through a diode; and a pin TXD of wireless data transmission module is connected with a contact of the pin RXD of the singlechip through a resistor and the diode. The intelligent roof displacement sensor has the advantages that an automatic meter calibration function is realized through a software analog potentiometer and accuracy of grade 0.5 is achieved; and the intelligent roof displacement sensor does not need to be irradiated and waken up by using a cap lamp, and automatic collection can be realized only when a worker carries the collector to pass by a meter approximately at an distance of 10 to 50m from the meter.

Description

technical field [0001] The invention relates to a mine pressure monitoring instrument, in particular to a roof separation instrument. Background technique [0002] At present, in coal mining, for the sake of production safety, it is necessary to monitor the separation of the roof. The principle of roof detachment monitoring is to use the base point displacement measurement method to drill a hole on the roof, set two base points in the borehole, and arrange the roof detachment sensor at the hole. When the roof moves, the positions of the two base points also change. Change, the base point is moved by the mechanical parts in the wire rope traction sensor, and the voltage signal is transmitted. The movement of the base point belongs to the change of linear displacement. The mechanical structure of the sensor converts the displacement movement into the rotational movement of angular displacement. The rotating part is connected to the angular displacement sensor, and the angular...
