Description

Technical Field

[0001] The utility model relates to an electronic monitoring system, in particular to a track-type monitoring system. Background Art

[0002] Track-mounted surveillance systems were originally designed for large-scale surveillance sites, such as exhibition halls and mining sites. Compared to traditional fixed surveillance systems, they save on camera installation and maintenance costs and, more importantly, offer flexible coverage.

[0003] Taking advantage of this flexibility and long maintenance intervals, large bank buildings are currently becoming potential applications.

[0004] However, rail-mounted surveillance systems are prone to noise during operation. This is fundamentally because they were originally designed for environments where silence was not a requirement. As the tracks slide and the equipment operates, vibrations are transmitted to the structure through the mounting brackets, generating low-frequency resonance and high-frequency noise. While banks, as indoor environments, don't require absolute silence, the noise of rail-mounted systems is a significant drawback.

[0005] The reason for this is that current installation techniques typically directly fasten the track and equipment to the bracket, lacking effective vibration damping and noise control measures. This traditional fixed connection method results in vibrations being directly transmitted to the mounting structure during operation, causing noise. This direct transmission of vibration and noise is difficult to effectively control, especially when using high-load or long track systems. Furthermore, existing single isolation materials often only buffer vibrations within a certain frequency range, with limited effectiveness against vibrations at other frequencies, failing to fully reduce noise.

[0006] To address the above issues, we have made a series of improvements. Utility Model Content

[0025] like Figure 1-3 As shown, a track-type monitoring system includes: a track 100, a bracket 200, a sliding device 300, a monitoring device 400, a drag chain 500, a slip ring 600, a multi-layer isolation structure 700 and a motor 800. The bracket 200 is fixed to the ceiling, the track 100 is connected to the bracket 200, the sliding device 300 is connected to the track 100 and the bracket 200, the monitoring device 400 is connected to the sliding device 300, the drag chain 500 is arranged outside the bracket 200, the slip ring 600 is arranged inside the track 100, the drag chain 500 is connected to the signal cable, the multi-layer isolation structure 700 is arranged between the sliding device 300 and the bracket 200, and the motor 800 is connected to the sliding device 300.

[0026] Among them, the sliding device 300 includes: a sliding joint 310, an extension arm 320, a transmission nut 330 and a screw rod 340. The two ends of the sliding joint 310 are respectively connected to the sliding grooves of the track 100 and the bracket 200. The middle of the sliding joint 310 is a rod-shaped structure. An extension arm 320 is provided on the inner side of the middle of the sliding joint 310. One side of the extension arm 320 is connected to the transmission nut 330. The transmission nut 330 is connected to the screw rod 340. The screw rod 340 is connected to the motor 800.

[0027] like Figure 4 As shown, the multi-layer isolation structure 700 includes: a shock-absorbing gasket layer 710, a sound-insulating foam layer 720, a metal elastic layer 730 and an anti-vibration spring pad 740. One side of the shock-absorbing gasket layer 710 is connected to the bracket 200 and the sliding joint 310, and the other side of the shock-absorbing gasket layer 710 is connected to one side of the sound-insulating foam layer 720. The other side of the sound-insulating foam layer 720 is connected to one side of the metal elastic layer 730, and the other side of the metal elastic layer 730 is connected to the anti-vibration spring pad 740.

[0028] The shock-absorbing gasket layer 710 is a silicone pad, the sound-insulating foam layer 720 is a closed-cell foam material, the metal elastic layer 730 is a thin sheet of elastic metal material, and the shock-resistant spring pad 740 is provided with a spring structure.

[0029] First of all, from a structural point of view, the track 100, the motor 800, the monitoring device 400, the drag chain 500, and the slip ring 600 are components of the currently common track monitoring system. As these are prior arts, a detailed description of the structural principles is not given. In this embodiment, the track 100 is made of aluminum alloy to ensure strength and durability while maintaining lightweight for easy installation and maintenance. The track is long and has a C-shaped cross section, which can accommodate the movement of the sliding device 300 in the slide groove inside the track. The main body of the monitoring device 400 is a high-definition camera that supports 4K or 8K and can monitor the situation in the area in real time. The camera is connected to the track 100 and the bracket 200 through the sliding device 300, and the monitoring range can be flexibly adjusted.

[0030] The drag chain 500 and slip ring 600 are responsible for the installation of power and signal cables.

[0031] The transmission method in the sliding device 300 is relatively complex, but it is also a basic screw transmission structure, including a sliding joint 310, an extension arm 320, a transmission nut 330 and a screw 340.

[0032] The motor 800 drives the screw rod 340 to rotate, and the transmission nut 330 on the screw rod 340 moves on the screw rod. The transmission nut 330 then transmits the linear force to the sliding joint 310 through the extension arm 320, so that the sliding joint 310 moves on the track 100 and the bracket 200.

[0033] Based on the above, it is the most traditional rail-type monitoring system.

[0034] The innovation of this utility model is divided into two aspects, but the ultimate goal is to reduce the noise of the track system.

[0035] First, the bracket 200 and the sliding joint 310 are added. The track 100 is not directly connected to the ceiling, but is fixed through the bracket 200. The two ends of the sliding joint 310 move on the track 100 and the bracket 200, and the middle seat is connected to the power structure. The principle is as follows: Reduce noise: The sliding joint 310 can absorb and disperse vibrations, reducing the resonance that may occur during rigid connection. It helps to reduce the noise during system operation, especially when moving at high speed or starting and stopping. Buffering effect: The sliding joint 310 can provide a certain buffer space between the track and the bracket. This helps to absorb sudden impact forces and protect the entire system. Adaptability: It allows slight displacement between the track 100 and the bracket 200, which can adapt to slight deformation or thermal expansion of the building. It increases the overall flexibility of the system. Reduce stress concentration: Compared with rigid connections, sliding joints can disperse stress more evenly and extend the life of the system.

[0036] To fill the gap between the bracket and the sliding mechanism 300, we added a multi-layered isolation structure 700 to prevent vibration from being directly transmitted to the building structure. The shock-absorbing gasket layer 710 is primarily used to absorb high-frequency vibrations, while the sound-insulating foam layer 720 is used to block mid- and low-frequency noise. The metal elastic layer 730 absorbs low-frequency vibrations and prevents vibration transmission caused by loose equipment installation. The anti-vibration spring pad 740 further reduces vibrations, effectively working within the low- and medium-frequency vibration range through the spring structure.

[0037] The multi-layered isolation structure 700 utilizes a layered design of different materials to effectively buffer vibrations of varying frequencies. The shock-absorbing pad layer 710 and the acoustic foam layer 720 absorb high- and mid-frequency vibrations, while the metal elastic layer 730 absorbs low-frequency vibrations. The anti-vibration spring pad 740 provides additional cushioning when needed, especially for high-amplitude vibrations. Furthermore, the flexible connector between the bracket and the isolation structure further reduces vibration transmission.

[0038] The combination of the two can greatly reduce noise and vibration, and improve the quietness and stability of the entire system.

[0039] Compared with the traditional technology, the utility model reduces the noise problem of track operation by improving the sliding device and adding a multi-layer isolation structure.

[0040] The above describes the specific implementation of the present invention, but the present invention is not limited thereto. As long as it does not deviate from the purpose of the present invention, the present invention can also have various changes.
