Inclined shaft anti-sliding monitoring system based on single chip microcomputer, and control method

Abstract

The invention discloses an inclined shaft anti-sliding monitoring system based on a single chip microcomputer, and a control method. A downward timing startup sensor (TS) and a downward timing shutdown sensor (TC) are active magnetoelectric sensors; the normally open contact of a first intermediate relay (KA1) is connected with the input point of the single chip microcomputer; a RESET is connectedwith the RES end point of the single chip microcomputer; the coil of a second intermediate relay (KA2) is connected with the output end of a coil driving chip; two horns and two lamps are connected in series to be connected with the other output point of the driving chip; and if overspeed happens, the second intermediate relay (KA2) is switched on, and an arrester does not rise. The system is notinfluenced by factors, including environment temperatures, dust, smoke, rays and the like, is free from maintenance, is high in antijamming capability, is free from abrasion, is unlikely to be damaged, is high in reliability and is convenient in installation and use.

Description

technical field [0001] The invention relates to an anti-rolling car monitoring system for an inclined shaft, in particular to a single-chip microcomputer-based monitoring system and a control method for an anti-rolling car in an inclined shaft. Background technique [0002] The inclined wells in the main lanes of the various panels in the underground mainly use small winches to lift equipment and materials for transportation. During the operation, due to various problems such as improper operation and product quality, the wire rope and the connecting device are broken or decoupled, resulting in a slipping accident. Once a rolling accident occurs, the consequences are very serious. [0003] When the wire rope and the connecting device break or decouple, the real-time speed of the mine car cannot be measured by the encoder in the winch. Common anti-rolling car methods are: 1. Measure the speed of the mine car by installing an encoder on the mine car axle. The disadvantage of...

AI Technical Summary

Problems solved by technology

Common anti-rolling car methods are: 1. Measure the speed of the mine car by installing an encoder on the mine car axle. The disadvantage of this method is that each mine car needs to install an encoder and use a battery for power supply. The speed signal needs to be transmitted wirelessly to the corresponding control system

2. By installing reflective patches on the mine cart, two sensors placed at fixed positions are used to measure the position change of the mine cart to measure the speed of the mine cart. The disadvantage of this method is that each mine cart needs to be installed Reflective patch, and due to the large amount of dust in the mine, the reflective patch machine is easily covered by dust, so the measurement fails

3. Install two travel switches on the track, and calculate the speed through the time when the mine car touches the two travel switches. The disadvantage is that the mine ground environment is harsh and the situation is complicated. The travel switch is repeatedly pressed and bounced, and stones and dust After entering, the limit switch is blocked, so that the car can not be effectively prevented from slipping.
