Problems solved by technology

[0002] Building construction safety has always been a topic of concern at home and abroad. The traditional method of using security guards and guards to monitor unsafe behaviors can reduce the risk of unsafe behavior, but because of the involvement of human factors, subjectivity and limitations More serious, resulting in less effective
[0003] The monitoring of the safety status can effectively monitor the construction site in real time, thereby improving the performance of safety management. However, the safety monitoring process in China is often superficial or neglected in execution. The existing technical project site personnel supervision system , mostly by humans to conduct security checks on helmets one by one or use surveillance cameras to shoot staff passing through the gates. If you are slack and do not take the initiative to find out the staff who go to work without wearing helmets, it may cause a series of safety hazards

Embodiment 1

[0035] When the staff enters the area detected by the laser ranging sensor, the first 5, second 6, and third 7 laser ranging sensors are automatically turned on, and the first 5 and second 6 laser ranging sensors measure the side pillars 1 and 2 The horizontal distance to the head of the staff, the vertical distance from the beam 3 to the head of the staff is measured by the third 7 laser ranging sensor, after the data is sent to the central processing unit, the project / factory preset stored by the central processing unit The size of the national standard safety helmet is identified. If the data is the same, the gate 4 is opened. After identifying the personnel entering the work site, the gate 4 is closed and waiting for the entry of the next staff member.

Embodiment 2

[0037]When the staff enters the area detected by the laser ranging sensor, the first 5, second 6, and third 7 laser ranging sensors are automatically turned on, and the first 5 and second 6 laser ranging sensors measure the side pillars 1 and 2 The horizontal distance to the head of the staff, the vertical distance from the beam 3 to the head of the staff is measured by the third 7 laser ranging sensor, after the data is sent to the central processing unit, the project / factory preset stored by the central processing unit The size of the national standard safety helmet is identified. If the data is different, the alarm device 9 is turned on. The staff can choose to wear the safety helmet or press the reset button 8 after finishing the standing posture. Personnel re-tested.

Abstract

The invention provides an engineering-used intelligent safety helmet detection device, which comprises a central controller, a gate main body and laser ranging sensors arranged on the gate main body,wherein the gate main body comprises a side column, a crossbeam and a gate; at least three laser ranging sensors are arranged; the first laser ranging sensor and the second laser ranging sensor are arranged on the side column of the gate; the third laser ranging sensor is arranged on the crossbeam of the gate; the head of a worker is recognized through the first laser ranging sensor, the second laser ranging sensor and the third laser ranging sensor to determine whether the worker wears the safety helmet; and after the central controller receives signals of the first laser ranging sensor, thesecond laser ranging sensor and the third laser ranging sensor, the gate is controlled to be opened or closed. Through integrated use of the three laser ranging sensors, whether the worker wears the safety helmet is judged in real time, the operation is safe and reliable, artificial subjective judgment factors are not involved, and the safe working environment in a factory is greatly improved.

Description

technical field [0001] The invention relates to the technical field of safety engineering protection, in particular, to an engineering intelligent safety helmet detection device. Background technique [0002] Construction safety has always been a topic of concern at home and abroad. The traditional method of human monitoring by security guards and guards to identify unsafe behaviors can reduce unsafe behaviors, but because of the participation of human factors, subjectivity and limitations more serious, resulting in poorer effect. [0003] The monitoring of the safety status can effectively monitor the construction site in real time, thereby improving the performance of safety management. However, the safety monitoring process in China is often sloppy or neglected in execution. The existing technology project site personnel supervision system , Most of the safety inspections are carried out manually on the safety helmets one by one or the staff who pass through the gate are...
