Abstract

The invention discloses an intelligent borehole stress sensor and a meter calibration method thereof. The intelligent borehole stress sensor comprises a singlechip (SINGLECHIP), a communication module RSM3485, an analog-to-digital (AD) conversion module, a digital display module, an operational amplifier, a resistance bridge type stress sensor, a calibration potentiometer, a wireless data transmission module and an intelligent data collector, wherein the wireless data transmission module is a highly-integrated super-low power consumption half-duplex micropower module embedded into a circuit of the singlechip and the communication module RSM3485. The intelligent borehole stress sensor has the advantages that an automatic meter calibration function is fulfilled through the software analog potentiometer and accuracy of grade 0.5 is reached; and the intelligent borehole stress 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 the meter approximately at a distance of 10 to 50m from the meter.

Description

technical field [0001] The invention relates to a coal mine monitoring instrument. Background technique [0002] At present, in coal mining, the roof pressure must be monitored for production safety. One of the monitoring methods is to monitor the roadway surrounding rock stress. During monitoring, several holes are drilled in the surrounding rock of the roadway, and stress sensors are installed in the holes. The stress sensor uses the principle of resistance strain load measurement to output a standard voltage signal, and the voltage signal is transmitted through the drilling stress sensor. The transmission output is sent to the monitoring substation. The monitoring sub-station can connect up to 64 drilling stress sensors, and the monitoring sub-station will patrol and display the data transmitted by each drilling stress sensor according to the order of address coding. Borehole stress sensors on the market are called borehole stress gauges or borehole stress monitors. ...
