Infrared imaging human body identification safety early warning apparatus of driving operation

Abstract

The invention belongs to the field of safety early warning of driving operation, and provides an infrared imaging human body identification safety early warning technology of driving operation, for the purposes of performing safety early warning in advance on pedestrians close to an driving machinery guard area, eliminating the possibility that personnel approaches a dangerous area and putting an end to personnel casualty accidents caused by driving operation. The technical scheme employed by the invention is as follows: the infrared imaging human body identification safety early warning apparatus of the driving operation comprises an infrared thermal imaging core used for performing thermal imaging on the pedestrians approaching the driving machinery guard area; an infrared image processing subsystem used for processing infrared sequence images acquired by the infrared thermal imaging core in real time and detecting and identifying the approaching pedestrians; and a single-chip microcomputer control module used for receiving a downlink instruction from the infrared image processing subsystem, and according to the downlink instruction, controlling an acousto-optic alarm apparatus to send emergency shutdown signals to driving machinery. The infrared imaging human body identification safety early warning apparatus of the driving operation is mainly applied to a large-scale machinery equipment safety monitoring occasion.

Description

technical field [0001] The invention belongs to the field of safety early warning for excavation operations, and in particular relates to an infrared imaging human identification safety early warning device for excavation operations. Background technique [0002] Tunneling machinery is playing an increasingly important role in various underground engineering constructions such as tunneling, underground mining, and underground plant excavation. During its operation, it is required that no one should approach the dangerous area of ​​excavation. However, due to the dark or safe environment of underground construction Affected by factors such as lack of awareness, operators often stray into dangerous areas and cause unnecessary injuries. In view of the above problems, the traditional solution is to set up guards as a warning. This method has subjective loopholes, and other personnel may still enter the area by mistake and cause danger. Therefore, in order to ensure the safety o...

Problems solved by technology

However, this method is also prone to false alarms and false alarms for heat sources or objects close to the excavation machinery, and it cannot accurately and effectively discriminate approaching pedestrians, which will affect the normal excavation work.
