Description

Technical Field

[0001] The invention relates to the technical field of safety helmet detection, in particular to a construction site safety helmet detection system. Background Art

[0002] A safety helmet is a hat that protects the head from injuries caused by falling objects and other specific factors. The safety helmet is composed of a helmet shell, a hat lining, a chin strap and accessories. The safety helmet can effectively protect the head, reduce impact and injury, and prevent accidental falling objects from causing damage to the head, such as falling objects from high altitudes and building collapses. During on-site operations, the safety helmet can withstand and disperse the impact of falling objects, protect or reduce the impact injury caused by falling from a height or the head hitting the ground first, and can save a person's life at a critical moment. However, most of the existing safety helmets are basically composed of a helmet shell, a hat lining, a chin strap and some simple accessories. The structure is relatively simple and can only provide a simple protection function for the head of the worker. It is not easy to realize the function of autonomously detecting whether the worker is wearing the safety helmet correctly and warning the worker. Therefore, some workers who fail to wear the safety helmet correctly will work at the construction site. When an accident accidentally occurs at the construction site, those safety helmets that are not worn correctly cannot effectively protect the head of the worker to the greatest extent, which greatly threatens the personal safety of the worker.

The rubber layer increases the friction between the plug-in block 7 and the slot 2, thereby preventing the plug-in block 7 from sliding out of the slot 2 on its own.

[0042] When in use, the staff first wears the cap body 1 on the head, then controls the chin strap 20 to pass through the inside of the Japanese-shaped buckle 19, tightens the chin strap 20, and controls the chin support 21 to slide along the outer side of the chin strap 20 to adjust its position until the chin support 21 is tightly against the staff's chin, and the short strap 18 and the chin strap 20 are tightly against both sides of the staff's cheeks, and the top of the indirect cap hoop 3 is tightly against the top of the staff's head, and also makes the top of the staff's head close to the contact sensor 10, then controls the insertion rod 16 to be pulled backward, and at the same time stretches the reset spring 17, so that the insertion rod 16 moves out of the inside of the socket 15, releases the fixation between the flexible mounting ring 12 and the connecting block 14, then controls the rear end of the flexible mounting ring 12 to be pulled outward along the inside of the connecting block 14, so that the flexible mounting ring 12 begins to tighten, and at the same time the flexible mounting ring 12 drives the contact sensor 2 13 Probe inwardly into the through hole 9 until the inner side of the contact sensor 2 13 is in close contact with the staff's head, then release the control of the insertion rod 16, and at the same time, the contraction force generated by the stretching of the reset spring 17 can drive the insertion rod 16 to move forward until the insertion rod 16 passes through the interior of the designated socket 15, and the flexible mounting ring 12 and the connecting block 14 can be re-fixed. When one of the contact sensors 10 and 13 is not in close contact with the staff's head, the controller module 24 will control the alarm module 26 to sound an alarm, prompting the staff to fail to wear it correctly. When both the contact sensor 1 10 and the contact sensor 2 13 are in close contact with the staff's head, the alarm module 26 stops sounding the alarm, and then the staff inserts the identity card into the identity authentication module 23. The identity authentication module 23 can verify and upload the identity card of the staff, and then the locator module 25 starts to locate the staff's position in real time.

[0043] When the system of the present invention is working, the battery module 27 will supply power to the contact sensor 1 10, the contact sensor 2 13 and the controller module 24 respectively, and the controller module 24 will control the battery module 27 to temporarily not supply power to the alarm module 26, the identity verification module 23 and the locator module 25. When the staff does not wear the cap body 1 correctly, the contact sensor 1 10 and the contact sensor 2 13 are not in contact with the head of the staff, or one group of sensors is not in contact with the head of the staff. The contact sensor 1 10 and the contact sensor 2 13 or one group will feed back an electronic signal to the controller module 24. The controller module 24 will control the circuit between the battery module 27 and the alarm module 26 to automatically close, so that the battery module 27 supplies power to the alarm module 26. At the same time, the alarm module 26 will sound an alarm to remind the staff that the cap body 1 is not worn correctly. Then the staff adjusts the tightness of the chin strap 20 and the flexible mounting ring 12. , the contact sensor 10 and the contact sensor 2 13 can be respectively placed close to the head of the staff member, and the contact sensor 10 and the contact sensor 2 13 will transmit the feedback information to the controller module 24 in the form of electronic signals again, and the controller module 24 will issue an instruction to control the circuit between the battery module 27 and the alarm module 26 to be automatically disconnected, so that the alarm module 26 stops issuing an alarm, and the controller module 24 will issue an instruction again to control the circuit between the battery module 27 and the identity authentication module 23 and the locator module 25 to be automatically closed, so that the battery module 27 starts to supply power to the identity authentication module 23 and the locator module 25, so that the identity authentication module 23 and the locator module 25 start to run, and the identity authentication module 23 can verify and check the identity card inserted by its internal staff, and the locator module 25 will upload the real-time location of the staff to the terminal system to realize real-time positioning of the staff.
