Abstract

The invention discloses an intelligent anchor rod sensor and a calibrating method thereof. The intelligent anchor rod sensor is composed of a singlechip microcomputer, a communication module RSM3485, an AD (Analog to Digital) conversion module, a digital display module, an operation amplifier, a resistance bridge type stress sensor and a wireless data transmission module, wherein the wireless data transmission module is embedded into a circuit between the singlechip microcomputer and the communication module RSM3485. When the intelligent anchor rod sensor is used, a miner light is prevented from being used for awakening, and the collection can be completed automatically as long as a worker walks through a side place about 10-15 meters away by taking a collector. An automatic calibration function is fulfilled through a software-simulation potentionmeter, and the precision is high up to more than grade 0.5.

Description

technical field [0001] The invention relates to a coal mine support bolt monitoring instrument. Background technique [0002] At present, in coal mine support, it is necessary to monitor the condition of support bolts for production safety. The bearing stress of the end-anchored metal anchor is reflected as the force of the anchor bolt and the pallet. When monitoring, install a resistance bridge stress sensor with a through hole between the nut of the anchor rod and the tray to measure the force of the anchor rod. The stress of the anchor rod is not the anchoring force of the anchor rod. The stress of the anchor rod reflects the The support capacity of the anchor to the roof. The anchor rod stress sensor is like this. Firstly, an elastic element is designed. When the force acts on the elastic element, the elastic body deforms, and 900 equal parts are pasted on the elastic body wall by 4 single-bridge strain gauges and 4 single-bridge strain gauges. Form a resistance full ...
