A visual recognition-based crushed stone transmission control system and method for mine development

Abstract

The application discloses a system and method for controlling crushed stone transmission in mining based on visual recognition, including: an apron feeder, a camera located at the position where the mouth of the apron is aligned with the apron feeder, a PLC control module and a background server; Among them, the camera is used to obtain the image information of the stones to be broken on the conveying plate of the apron feeder, and transmits the obtained image information to the background server; the background server is used to calculate according to the received image information The proportion of large and small stones on the conveyor plate of the current apron feeder; the PLC control module is used to control the current value input to the motor of the apron feeder according to the calculated proportion of large and small stones to control the apron feeder. The frequency at which the feeder feeds stones into the crusher. The application can not only maximize the role of the crusher, but also prevent the jamming of the crusher, etc., and realize the fully automatic transmission of crushed stones in mining equipment, improve work efficiency, and reduce costs.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a visual recognition-based gravel transmission control system and method for mining. Background technique [0002] In the actual mining production, it is necessary to transport the mined large rocks to the crusher through the feeder for crushing operation. [0003] At present, most of the existing technologies control the feeding frequency of the feeder by manually setting the current value to ensure that the frequency of the feeder and the crusher are consistent. However, this method requires manual adjustment of the feeding frequency of the feeder in real time according to the crushing speed of the crusher. If the feeding is too fast, it will easily cause the crusher to block and may damage the equipment; if the feeding is too slow, it will also cause The idling of the crusher leads to the idle waste of the crusher and the low crushing efficiency. Therefore, it requires a long-...

However, this method requires manual adjustment of the feeding frequency of the feeder in real time according to the crushing speed of the crusher. If the feeding is too fast, it will easily cause the crusher to block and may damage the equipment; if the feeding is too slow, it will also cause The idling of the crusher leads to the idle waste of the crusher and the low crushing efficiency. Therefore, it requires a long-time man on duty to adjust the set current value in real time and then adjust the feeding frequency of the feeder. The technical requirements for manual labor are very high. The cost is high; moreover, due to the inevitable errors in manual operation or untimely feedback, the motor will be burned out due to excessive current, shortening the service life of the equipment, and thus increasing the cost of mining
