[0030] This invention can be implemented in many ways and has various embodiments, therefore specific embodiments are illustrated and described in the accompanying drawings. However, this is not intended to limit the invention to specific implementations, but should be understood to include all modifications, equivalents, and even substitutions that fall within the spirit and technical scope of this invention.

[0031] like Figure 1-5As shown, this embodiment provides a protective helmet for construction workers, which is worn on the head of construction workers. It consists of: 1-helmet shell, 2-helmet liner, 3-chin strap and accessories, sensors and positioning unit.

[0032] 1- Helmet shell, 2- Helmet liner, 3- Chin strap and accessories must meet the requirements of the national helmet standard GB2811–2019. That is, the shape is a conventional safety helmet, 2- Helmet liner is set on the inner surface of 1- Helmet shell, and 3- Chin strap is attached to the two sides of the lower end of 1- Helmet shell.

[0033] Specifically, the helmet body 1-shell is composed of 12-shell, 13-visor, 14-brimmed, 15-top rib, etc., and has 45-identity identification QR code on its outer surface. The QR code can be printed on the shell surface by offset printing or other methods. The shell surface can have a film-like insertion slot, and the QR code can be inserted therein.

[0034] 2-The liner is a general term for the components inside the hat shell, consisting of 21-the headband, 22-the sweatband, 23-the liner strap, and 24-the cushioning device.

[0035] 3-The chin strap is a strap that is tied to the chin for fixation, consisting of 31-the ties and 32-the locking clips.

[0036] The sensor and positioning unit includes a 41-power switch (i.e., electrically connecting all electrical components and / or power sources, used to start or stop all electrical equipment) mounted at four locations on the rear side of the 2-cap liner; a 46-button battery pack (i.e., electrically connecting all electrical components and providing them with power); a 47-safe and correct wearing LED indicator (i.e., warning device); and a 48-buzzer (i.e., warning device). 47 and 48 can also be optionally configured.

[0037] The sensors and positioning unit also include a 42-human body sensor chip installed on the 3-chin strap (generally installed on the upper and lower sides of the worker's cheeks to detect whether the chin strap fits the skin, i.e., by moving up, down, left, and right to ensure that the chin strap fits snugly against the head and is securely worn).

[0038] The aforementioned 42-human-body sensor chip and the warning device are connected via a circuit, generally forming a loop. When the power is turned on and the device is in place, each 42-human-body sensor chip has or is connected to a sensor switch. When the 42-human-body sensor chip is in contact with the human body, it generates an electrical signal that turns off the sensor switch. When all switches in the circuit are turned off, the warning device stops alarming (i.e., it does not flash or beep). Conversely, if the device is not properly worn, it will continue to alarm.

[0039] Furthermore, to further ensure proper wearing, a sensor similar to a seatbelt buckle is installed at the 32-locking buckle, which can detect whether the buckle is locked. This sensor is also located in the aforementioned loop and is equipped with or connected to a sensor switch. When locked, it generates an electrical signal to turn off the sensor switch.

[0040] In addition, considering the attendance of on-site construction personnel and safety considerations, 43-position positioning chips (i.e., traditional GPS chips) and 44-signal transmitters are installed at four locations on the back of the 2-cap liner. The signal transmitter can send the location information of the construction personnel to the remote end in real time, which is convenient for assessment and determination of personnel location. In addition, the aforementioned sensors for wearing safety considerations can also send signals to the remote end through the signal transmitter.

[0041] While the foregoing description has focused on embodiments, these are merely illustrative and do not limit the scope of the invention. Those skilled in the art will understand that various modifications and applications not illustrated above can be made without departing from the essential characteristics of the embodiments. For example, the constituent elements specifically shown in the embodiments can be implemented through modifications. Furthermore, various differences related to such modifications and applications should be interpreted as including within the scope of the invention as defined in the appended claims.
