Problems solved by technology

[0003] In order to ensure the safety of life during the construction process, all personnel on the construction site need to wear safety helmets. The construction intensity and the construction environment have a greater impact on the construction personnel, which can easily cause emotional and physical fatigue of the construction personnel. After working for a long time, his physical and mental strength will gradually enter a state of fatigue, his attention will be scattered, his ability to judge and respond will decline, his vision will become blurred, and his hearing will also begin to decline.
Overtired construction workers will feel sleepy or even doze off during work, so fatigued construction can easily lead to construction accidents

Embodiment 2

[0045] On the basis of Example 1, combined with figure 1 and figure 2 , the alarm module 17 includes a buzzer 9, an LED light 8, and a display screen 7, the LED light 8 is connected to the display screen 7, the buzzer 9 and the display screen 7 are connected to the microprocessor 15, and the buzzer Device 9 and display screen 7 are all located at the upper end of safety helmet 1.

[0046] The alarm module 17 mainly consists of three parts: a buzzer 9, an LED light 8, and a liquid crystal display 7. The green light is on when the construction personnel are working normally, and the liquid crystal display 7 prompts attention to safe construction. When the construction personnel enters a critical state of fatigue, the microprocessing Device 15 controls buzzer 9 to sound intermittently, and green indicator light is extinguished, and yellow indicator light is on, and liquid crystal display screen 7 prompts construction personnel to pay attention to rest simultaneously, if constru...

Embodiment 3

[0048] combine figure 1 and image 3 , the respiratory signal sensor 11 adopts a variable pole-pitch capacitive sensor, the respiratory signal sensor 11 is belt-shaped, and the respiratory signal sensor 11 includes an insulating structure 111 made of polyolefin material and two ends of the insulating structure 111. Composed of metal electrodes 112, the metal electrodes 112 are made of copper foil tape, and the respiratory signal sensor used uses a pole-pitch capacitive sensor to detect changes in the chest and abdominal cavity caused by human breathing to detect human breathing. It is made of polyolefin material, soft, It has good insulation and stretching performance, and will not cause harm to people and the environment. The breathing is measured in the form of a belt. The distance between the two electrodes of the sensor changes greatly, and the amplitude of the obtained breathing waveform is relatively large, and the anti-interference ability is strong.

Description

technical field [0001] The invention belongs to the technical field of safety helmets, and in particular relates to a safety helmet-based engineering construction personnel fatigue detection system. Background technique [0002] As one of the pillar industries of the national economy, the construction industry is a field with extremely high safety requirements. Safety accidents at construction sites are still happening, and the explanations for the reasons for the accidents are relatively vague. As the most active factor, people have a great impact on safety. There is an inevitable connection between the occurrence of the accident. However, construction workers who are responsible for safety at the construction site are highly stressed and stressed, have irregular work and rest time, and fatigue problems are ubiquitous both physically and psychologically. Therefore, the work fatigue of construction workers is one of the important reasons that lead to the decline of construc...
