[0021] This application provides a construction safety early warning helmet. Figure 1 This is a schematic diagram of the connection structure of various modules of a construction safety early warning helmet, such as... Figure 1 As shown, a construction safety early warning helmet includes: Positioning module 1 is fixedly installed on one side of the rear of the helmet; Processing module 2 is fixedly installed on the other side of the rear of the helmet; The early warning module 3 includes a vibration unit 32 and a buzzer unit 31; Power module 4; The positioning module 1 is electrically connected to the processing module 2 and is used to transmit positioning data to the processing module 2. The early warning module 3 is electrically connected to the processing module 2 and is used to send an early warning command to the early warning module 3 based on the positioning data of the positioning module 1. The power module 4 is electrically connected to the positioning module 1, the processing module 2 and the early warning module 3 via power lines.

[0022] Specifically, the construction safety early warning helmet is connected to Building Information Modeling (BIM) and can extract hazardous areas from the BIM in real time, including the coordinates and attributes of near-edge openings, hoisting paths, etc. The positioning module 1 tracks the location of personnel or management personnel; the processing module 2 processes the building information and personnel location, and then issues early warnings based on the processing results.

[0023] It should be noted that the improvement of this application lies in the connection relationship between the various functional modules in the construction safety early warning helmet. The processing module 2 determines whether the personnel are at the target location based on real-time personnel positioning data and building model information (map information), and then triggers the early warning information. This is existing technology and is not protected by this application.

[0024] In summary, the construction safety early warning helmet provided in this application embodiment achieves a reasonable spatial layout and prevents signal interference by separately positioning the positioning module 1 and the processing module 2 on the rear sides of the helmet. The early warning module 3 includes a vibration unit 32 and a buzzer unit 31. The positioning module 1 and the processing module 2 are electrically connected, and the early warning module 3 is also electrically connected to the processing module 2. The positioning module 1 can transmit real-time collected location data to the processing module 2, which quickly analyzes the location information. When it detects that a person has entered a dangerous area, it immediately triggers a linkage mechanism—providing a tactile warning through the vibration unit 32 and emitting an audible alarm through the buzzer unit 31, forming a multimodal early warning, improving the perception of the warning, and enhancing construction safety. This solves the problem that traditional construction safety helmets in related technologies have limited functionality and are difficult to use for hazard warning.

[0025] In one embodiment, the vibration unit 32 includes four vibration units 32, which are respectively distributed in the front, back, left and right directions of the helmet.

[0026] Optionally, there can be four vibration units 32, distributed in the front, rear, left, and right directions of the helmet. By setting vibration units 32 in the front, rear, left, and right directions, a spatial three-dimensional tactile warning is constructed. When the processing module 2 detects a hazard, it can intelligently activate the corresponding vibration unit 32 according to the location of the hazard source (e.g., if the hazard is on the left, vibration will be triggered on the left). This directional warning method allows construction workers to quickly and intuitively judge the direction of the hazard, significantly shortening the reaction time. It is worth noting that the method of intelligently activating the corresponding vibration unit according to the location of the hazard source when the processing module 2 detects a hazard, and the directional warning method allows construction workers to quickly and intuitively judge the direction of the hazard, is existing technology. For example, patent application number CN201910389192.2, "Intelligent Positioning Method for Ultra-High-Speed ​​Collision Sources Based on Vibration Signal Processing," both involve issuing warnings in different directions when a hazard is detected.

[0027] In one embodiment, the vibration unit 32 includes a linear vibration motor, wherein the linear vibration motor includes: Vibration generating unit, used to generate mechanical vibration; The drive control unit is used to receive the warning signal from the processing module and control the vibration generating unit to work. A support assembly is used to elastically fix the vibration generating unit and the drive control unit to the inner wall of the helmet; The vibration generating unit is connected to the drive control unit via an electrical connector; The drive control unit is connected to the processing module 2 via a data transmission interface; The vibration generating unit and the drive control unit are elastically fixed to the inner wall of the helmet by the support assembly.

[0028] Optionally, the vibration unit 32 is a linear vibration motor (LRA), specifically model CLF-25WX02, with a vibration frequency range of 80-250Hz. Electrical components are connecting elements that transmit electrical signals or power, including circuit boards and wires. Through the connection between the vibration generating unit, drive control unit, and elastic support assembly, efficient and reliable tactile warnings are achieved. The elastic support assembly, through a buffer-fixing method, ensures effective transmission of vibration energy while reducing resonance interference and structural wear.

[0029] In one embodiment, the helmet further includes a calling module, the calling module comprising: A voice acquisition unit is used to receive the user's voice input; A wireless communication unit is used to establish a communication connection with a remote management platform; The control unit is used to respond to the input signals of the voice acquisition unit and trigger the wireless communication unit to work; An emergency call button, located on the side of the helmet, is used to manually trigger the emergency call function.

[0030] Optionally, the voice acquisition unit is electrically connected to the control unit, converting voice signals into control commands; the wireless communication unit is bidirectionally connected to the control unit, enabling the transmission of voice data and the reception of remote commands; the emergency call button is directly connected to the control unit, providing a trigger channel. When construction workers encounter danger, they can activate a distress call through natural voice interaction (voice acquisition → control unit → wireless communication), or they can use a physical button to trigger an emergency alarm when they cannot speak (button → control unit → wireless communication). Simultaneously, the wireless communication unit maintains a continuous bidirectional data link with the management platform, improving the success rate of distress calls in emergency situations.

[0031] In one embodiment, the helmet includes a protective shell, which includes an outer shell body, a buffer layer, and an internal support.

[0032] Optionally, the helmet's protective shell employs a three-layer composite structure design. The outer shell forms the first impact barrier, the cushioning layer can be energy-absorbing foam material tightly bonded to the inner side of the outer shell to form an energy-absorbing band, and the internal support structure provides structural support. This three-layer composite structure design enhances the helmet's strength.

[0033] In one embodiment, the positioning module 1 includes an NXP SR040 positioning chip, a housing, fixing screws, and an external data cable. The housing is fixedly installed on the helmet by the fixing screws. The NXP SR040 positioning chip is installed in the space formed by the housing and the helmet. The NXP SR040 positioning chip is electrically connected to the processing module 2 through the external data cable.

[0034] Optionally, the NXP SR040 is a secure ultra-wideband RF semiconductor solution chip for IoT devices, designed by NXP. It utilizes stainless steel mounting screws for a rigid connection to the rear of the helmet, ensuring stable installation of the positioning module 1 in vibration environments. The external data cable employs a shielded twisted-pair structure, with one end connecting to the positioning chip via a waterproof connector, and the other end connecting to the dedicated data interface of the processing module 2.

[0035] In one embodiment, the processing module 2 includes an RK1808 chip, a housing, fixing screws, and an external data cable. The housing is fixedly mounted to the helmet using the fixing screws. The RK1808 chip is installed in the space formed by the housing and the helmet. The RK1808 chip is electrically connected to the processing module 2 via the external data cable. Optionally, the RK1808 chip is a 4 TOPS computing power chip launched by Rockchip Technology Co., Ltd. In summary, the construction safety early warning helmet provided in this application embodiment achieves a reasonable spatial layout and prevents signal interference by separately positioning the positioning module 1 and the processing module 2 on the rear sides of the helmet. The early warning module 3 includes a vibration unit 32 and a buzzer unit 31. The positioning module 1 and the processing module 2 are electrically connected, and the early warning module 3 is also electrically connected to the processing module 2. The positioning module 1 can transmit real-time collected location data to the processing module 2, which quickly analyzes the location information. When it detects that a person has entered a dangerous area, it immediately triggers a linkage mechanism—providing a tactile warning through the vibration unit 32 and emitting an audible alarm through the buzzer unit 31, forming a multimodal early warning, improving the perception of the warning, and enhancing construction safety. This solves the problem that traditional construction safety helmets in related technologies have limited functionality and are difficult to use for hazard warning.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
