[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:
[0024] like Figures 1 to 3 As shown in the figure, this utility model embodiment discloses a multifunctional intelligent video and voice monitoring device, including a safety helmet body 1, a multifunctional box 2, and a monitoring component. The multifunctional box 2 is fixedly mounted on the front end of the safety helmet body 1. The multifunctional box 2 is equipped with a voice call module 3, a video module, and a communication module. The video module is equipped with a first camera 4. The monitoring component includes a mounting base 8, a universal tube 6, and a second camera 7. One end of the universal tube 6 is mounted on the mounting base 8, and the other end of the universal tube 6 is equipped with the second camera 7. The first camera 4, the voice call module 3, and the second camera 7 are respectively connected to the communication module.
[0025] A multi-functional box 2 is designed on the safety helmet body 1, integrating a voice communication module 3, a video module, and a communication module. The first camera 4 collects image or video information of the work area, while the second camera 7 collects image or video information of the workers. The communication module sends the image and video information to the server and monitoring center, and is also used for receiving and sending voice information. Workers wearing safety helmets can view the on-site work situation through the images or videos captured by the first camera 4. If problems are found, timely and effective communication can be established with the on-site workers through the voice communication module 3. The second camera 7 can also be used to check whether workers are following work procedures, identify any physical abnormalities, etc. If violations are found, an early warning can be issued through the voice communication module 3. In case of an emergency, personnel can be notified immediately for assistance.
[0026] The voice call module 3 includes a microphone and a speaker, which are existing technologies. The first camera 4 can be designed to have an adjustable vertical tilt angle for shooting, or it can be designed to shoot from any 360° angle, depending on the actual shooting needs.
[0027] Furthermore, the second camera 7 is fixedly connected using a universal joint 6. The universal joint 6 can be bent freely and in multiple segments, and after being bent at a certain angle, it keeps the second camera 7 fixed on it from shaking or shifting. The position of the second camera 7 in front of the worker's left or right can be adjusted using the universal joint 6 to avoid obstructing the shooting direction of the first camera 4. The weight, size, etc. of the second camera 7, as well as the length and diameter of the universal joint 6, can be adjusted according to the actual situation. Installing the multi-functional box 2, the second camera 7, and other components on the safety helmet body 1 does not damage its original structure or stress.
[0028] The universal tube 6 is existing technology. It can be used as a reference for fixing the lamp bead assembly to the lamp holder through the universal tube 6 in existing lamps, allowing for free bending and multi-angle adjustment. The second camera 7 connected to the universal tube 6 can also serve as a backup camera. When the first camera 4 fails, the second camera 7 can be adjusted to capture image or video information of the work area by adjusting the universal tube 6. However, this adjustment relies on manual adjustment by the operator, which limits the precise control of the image acquisition angle.
[0029] In some embodiments, the interior of the multi-functional box 2 is also equipped with a lighting module 5, which includes a laser light and a fill light.
[0030] The laser light can be located above or below the first camera 4. The laser light is used to emit a laser beam to locate the work area and can help clarify the shooting position of the first camera 4. The fill light can be located above, below, to the left or right of the first camera 4. The fill light is used when the light source in the on-site work environment is insufficient, such as on cloudy days or at night, to help the first camera 4 complete the acquisition of clear images or pictures.
[0031] Furthermore, the front of the multi-functional box 2 is a visible shell.
[0032] In some implementations, a back-end server is also provided, which is connected to the voice call module 3, the video module, the second camera 7 and the barometer sensor respectively through the communication module.
[0033] Furthermore, a barometer sensor is also installed inside the multi-functional box 2. The barometer sensor is used to collect altitude data and is connected to the communication module.
[0034] Using data from the barometer sensor, video module, and voice communication module 3, the system determines whether workers are operating at heights. The abnormal behavior monitoring system in the monitoring center detects safety belts and fall arrest devices, enabling the monitoring center to monitor the safety equipment and wearing status of workers.
[0035] Furthermore, the communication module includes a WiFi module. This intelligent video and voice monitoring device wirelessly connects to the intelligent gateway of the field workstation, possessing WiFi hotspot functionality and connecting by searching for WiFi hotspots. The workstation integrates multiple radio frequency modules, providing transmission of various audio, video, and voice intercom functions. It can perform local processing and analysis of information such as voice, images, and location data for video monitoring, violation detection, etc., and transmit various analyzed data from the field back to the remote command center in real time to complete tasks such as on-site information collection and command.
[0036] In practical applications, the intelligent video and voice monitoring module is equipped with a split structure; the intelligent module is detachable and can be separated from the safety helmet body 1. The intelligent video and voice monitoring module does not affect the structure or stress of the safety helmet body 1. It consists of a human-machine interface module, audio and video module, power supply module, supplementary lighting module, and communication module. Image stabilization is designed for the camera to ensure that the captured video images can be used for AI intelligent analysis. The composition of each component is shown in the table below.
[0037] In some implementations, a button module 9 is also provided, which is located on one side of the helmet body 1. The button module 9 includes an image acquisition button, a supplementary light button, a laser positioning button, a voice call button, and a power switch.
[0038] The wiring inside the multi-functional box 2 is integrated and extended to the rear end of the safety helmet body 1. The wiring of components such as the voice communication module 3, video module, communication module, lighting module 5, and barometer sensor inside the multi-functional box 2 can be integrated and extended externally to the rear end of the safety helmet body 1, and connected to the power module carried by the worker's safety belt, which provides power.
[0039] In some implementations, the interior of the universal tube 6 is a hollow structure, and the extension of the second camera 7's wiring is routed through the universal tube 6.
[0040] Furthermore, the multi-functional box 2 has a through hole at one end near the universal tube 6, and the wiring of the second camera 7 is connected to the multi-functional box 2 through the through hole.
[0041] The wiring of the second camera 7 is built into the universal tube 6, and extends from one end of the universal tube 6 through the through hole into the multi-function box 2, integrating with the wiring of components such as the voice call module 3, video module, communication module, and light module 5 into an external unit.
[0042] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
