Description

Technical Field

[0001] This utility model relates to a regional mobile magnetic intercom monitoring device, belonging to the field of work monitoring technology. Background Technology

[0002] In the petrochemical industry, special operations such as confined space work and hot work, as well as related maintenance and repair work, are often hampered by limited ambient light, restricted work areas, on-site signal shielding, and personal factors affecting the workers. This can lead to a series of problems, such as the inability of monitoring personnel to enter the site, unclear monitoring videos due to lighting conditions, or the inability of monitoring personnel to communicate with the workers in real time. Ultimately, this can result in workers violating regulations and operating procedures, or inadequate monitoring by monitoring personnel, leading to accidents that result in personal injury or death.

[0003] Currently, video surveillance equipment is typically installed in special operation sites of companies such as CNPC and Sinopec. However, because these devices are installed at fixed locations, the video coverage of the work area is often incomplete. Furthermore, the fixed buried wiring is prone to aging and insulation failure. In addition, most monitoring equipment cannot achieve explosion-proof structures, which can generate accidental sparks that can easily ignite leaked gases in confined spaces, leading to combustion and explosion, and causing casualties.

[0004] Furthermore, relying solely on either intercom or video conferencing methods can lead to delays in information transmission within and outside confined spaces due to signal transmission issues. Therefore, there is an urgent need for a more comprehensive and compact monitoring device to adapt to confined workspace environments and ensure accurate, clear, and timely information transmission within and outside these spaces during operations. Utility Model Content

[0005] This invention aims to address the problem of inadequate monitoring of the interior of confined spaces during operations, and provides a regional mobile magnetic intercom monitoring device.

The lighting main body is controlled to turn on and off via a switch assembly. The second housing is also equipped with a first cable connector electrically connected to the camera integrated circuit board.

[0010] The speaker assembly and the microphone assembly are respectively mounted on the second housing and are both electrically connected to the camera integrated circuit board;

[0011] The support assembly is mounted on the second housing and has a magnetic base fixed to its bottom. The support assembly is used to support the camera assembly at different angles.

[0012] The monitoring equipment includes a third housing, a display screen and a third integrated circuit board disposed inside the third housing, and a second cable connector, a third cable connector, a first power button, a second power button, an antenna and a charging connector mounted on the third housing and electrically connected to the third integrated circuit board. A walkie-talkie is also installed on the outside of the third housing and is connected to the third integrated circuit board via a third cable.

[0013] Furthermore, the switch assembly includes a push rod and a magnetic switch. The push rod is mounted on the first housing via a mounting plate, and the magnetic switch is mounted on the first integrated circuit board. When the lighting body is turned on, the push rod and the magnetic switch are arranged vertically opposite each other.

[0014] Furthermore, a data export port is also installed on the first housing, and the data export port is electrically connected to the first integrated circuit board.

[0015] Furthermore, the second housing includes a front cover, a main cover, and a rear cover that are fixedly connected from front to back. The main cover, the front cover, and the rear cover are all cylindrical structures, and the front end of the front cover and the rear end of the rear cover are both machined with a retaining edge. The camera glass is clamped inside the front cover by a camera glass pressure plate.

[0016] Furthermore, the speaker assembly includes a speaker body and a speaker fixing ring. The speaker body is electrically connected to the camera integrated circuit board. A protective steel mesh is installed inside the back cover, and the protective steel mesh is sandwiched between the speaker fixing ring and the retaining edge of the back cover.

[0017] Furthermore, the support assembly includes a first support frame, a second support frame, and a third support frame, wherein the first support frame is fixedly mounted on the second housing, the rear part of the second support frame is rotatably mounted on the bottom of the first support frame in the vertical direction, the upper part of the third support frame is rotatably mounted on the front part of the second support frame in the horizontal direction, and the magnetic base is fixedly mounted on the bottom of the third support frame.

[0018] Furthermore, both the lighting unit and the camera integrated circuit board are located on the front side of the monitoring equipment.

[0019] Furthermore, the third housing includes a front housing and a rear housing that are fixedly connected to each other.

[0020] Furthermore, a handle is installed on the third housing.

[0025] This utility model's regional mobile magnetic intercom monitoring device can realize the monitoring, surveillance, and storage of petrochemical maintenance and repair work environments.

[0026] The video signal in the work space is collected in real time by the camera component, and the area is illuminated by the lighting component. The video signal collected by the camera component in the monitoring device is transmitted to the monitoring device in real time through the first cable connection, so that the outside of the work space can monitor the inside of the work space in real time.

[0027] The first cable connection ensures that the audio receiving component in the monitoring equipment remains in a receiving state and transmits the audio signal to the monitoring equipment in real time; simultaneously, the speaker assembly receives the audio signal emitted by the walkie-talkie in the external monitoring equipment of the work space. This enables real-time communication between the inside and outside of the work space.

[0028] In this invention, the structural design enables simultaneous audio acquisition and transmission, video acquisition and transmission, and regional supplementary lighting. In special circumstances such as limited transmission, audio and video serve as substitutes for each other, effectively avoiding the problem of untimely information transmission within and outside confined spaces.

[0029] This utility model can realize regional networking function, and upload the video information of on-site monitoring to the relevant security network platform through the antenna, so that the background monitoring information can be stored on the network platform.

[0030] This utility model is particularly suitable for installation, dismantling, emergency rescue operations, fire-fighting linkage monitoring, and other special operation sites such as confined spaces. Attached Figure Description

[0079] The main lighting unit and the camera integrated circuit boards 1-24 are all located on the front side of the monitoring device 1. This design ensures that the lighting area is the same as the video acquisition area, maximizing the supplementary lighting for the camera area; at the same time, the supplementary light structure is located above the camera, serving as a handle function and allowing for explosion-proof lifting of the monitoring device.
