Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] This application aims to overcome the shortcomings of existing video storage devices, such as narrow operating voltage range, poor environmental adaptability, and poor electromagnetic compatibility. To address the above deficiencies or improvement needs of the prior art, this application provides a video storage device that adopts an Ethernet video acquisition system, enabling 32-channel video access and storage. The device operates on a 28V DC power supply, accepts multiple monitoring video recordings, and is adaptable to low-temperature operation and operation in vibration and transportation environments. This application features a reasonable design, high reliability, and good environmental adaptability, making it more suitable for the video storage requirements of special equipment and vehicles compared to non-rugged video storage devices. The embodiments of this application are described below with reference to the accompanying drawings.

[0038] See Figure 1 The video storage device provided in this application embodiment may include: a first aviation socket 10, a video recording board 20 connected to the first aviation socket 10, and a wide-temperature hard disk 30 connected to the video recording board 20;

[0039] The video recorder 20 collects video data through the first aviation socket 10 and writes the video data to the wide-temperature hard disk 30.

[0040] In this embodiment, an Ethernet digital communication-based video recording board 20 is used to acquire video data and store it in a wide-temperature hard disk 30. The video recording board 20 is the core circuit for video acquisition and storage; it can receive multiple external Ethernet video data inputs and store the video data in the wide-temperature hard disk 30.

[0041] In addition, the video recorder 20 itself is designed to be waterproof, shockproof, and resistant to marine environments.

[0042] In this embodiment, the first aviation socket 10 and the video recorder 20 are connected via Ethernet, supporting the input of multiple video data streams.

[0043] One or more video data streams enter the recording board 20 from the first aviation socket 10. The recording board 20 collects one or more video data streams and writes the collected video data to the wide-temperature hard disk 30 connected to it.

[0044] Furthermore, in some embodiments, the video recorder 20 is connected to the wide-temperature hard disk 30 via a SATA cable.

[0045] In this embodiment, the video recorder 20 is connected to the wide-temperature hard disk 30 via a SATA cable.

[0046] After the video recorder 20 acquires the video data, it writes the video data to the wide-temperature hard disk 30 via the SATA cable between the recorder 20 and the wide-temperature hard disk 30.

[0047] In this embodiment, the wide-temperature hard disk 30 is used for video data storage and has the advantages of large capacity, good shock resistance, and wide operating temperature range.

[0048] The video storage device provided in this application embodiment acquires video data by using a recording board connected to a first aviation socket and stores it in a wide-temperature hard drive with advantages such as large capacity, good vibration resistance and wide operating temperature range. The aviation socket design further enhances the vibration resistance and transportation capabilities to adapt to normal video storage operations in low temperature, vibration and transportation environments, thereby improving the reliability and environmental adaptability of video storage.

[0049] Furthermore, in some embodiments, the video storage device may further include:

[0050] The power module is used to provide power signals to the video recorder and the wide-temperature hard drive.

[0051] In this embodiment, the video storage device further includes a power module. This power module can be a DC power supply. It can be used to provide the power signals required for the normal operation of the video recorder 20 and the wide-temperature hard disk 30.

[0052] For example, the power module can use a DC power supply in the range of 18V to 36V.

[0053] Furthermore, in some embodiments, the video storage device may further include:

[0054] A second aviation socket connected to the power module, a soft-start circuit connected to the second aviation socket, a DC filter connected to the soft-start circuit, and an isolated power module connected to the DC filter;

[0055] The soft-start circuit is used to suppress the inrush current generated when the power module starts up and output the first power signal;

[0056] A DC filter is used to filter out interference and ripple in the first power supply signal and output the second power supply signal.

[0057] The isolated power supply module is used to isolate and transform the second power signal to obtain a third power signal and a fourth power signal. The third power signal is used to provide a power signal for the video recorder, and the fourth power signal is used to provide a power signal for the wide-temperature hard disk.

[0058] Please see further. Figure 2 The video storage device also includes a soft-start circuit 40, a DC filter 50, and an isolated power supply module 60.

[0059] The soft-start circuit 40 is connected to the output of the second aviation socket (not shown in the figure) in the aviation socket. The second aviation socket serves as a power supply aviation socket, and its input is connected to the power module. This soft-start circuit can be used to suppress the inrush current generated when the power module starts up and output a power signal, namely the first power signal.

[0060] The soft-start circuit 40 can be an existing soft-start circuit, used to suppress the inrush current generated when the power module starts up, and has the function of protecting the upstream power module, which can improve the power adaptability of the equipment.

[0061] Taking the power module using a 28V DC power supply as an example, the inrush current generated when the 28V DC power supply starts is suppressed by the soft-start circuit 40, and then a 28V DC voltage signal is generated.

[0062] The DC filter 50, connected to the soft-start circuit 40, can be used to filter out interference and ripple of the first power signal and output a power signal, namely the second power signal.

[0063] The interference in the first power signal refers to high-frequency noise from the external power module, which may affect the normal operation of the circuit. A DC filter attenuates these high-frequency signals by designing specific circuits (such as LC or RC circuits), thus ensuring a cleaner output power signal. The ripple in the first power signal refers to the low-frequency AC signal superimposed on the DC power output. A DC filter filters out this ripple, providing a smoother DC power signal output.

[0064] For example, the DC filter 50 filters out interference and ripple in the 28V DC voltage signal output after the soft-start circuit, resulting in a smoother and cleaner 28V DC voltage signal.

[0065] The isolation power supply module 60 is connected to the DC filter 50 and can be used to isolate and transform the second power signal to obtain a third power signal for providing power to the video recorder 20 and a fourth power signal for providing power to the wide-temperature hard disk 30.

[0066] The isolated power supply module 60 can use an existing isolated power supply module to realize input voltage conversion, converting the 18V to 36V DC voltage signal into the 12V DC voltage signal required by the video recorder 20, while also having voltage isolation function.

[0067] For example, the isolated power supply module 60 performs isolation conversion on the 28V DC voltage signal output by the aforementioned DC filter 50 to obtain a 12V DC voltage signal and a 5V DC voltage signal. The 12V DC voltage signal enters the recording board 20 to provide a power signal, and the 5V DC voltage signal enters the wide-temperature hard disk 30 to provide a power signal.

[0068] The video storage device provided in this application embodiment achieves wide-range DC power supply voltage conversion through an isolated power module, providing voltage supply for the recording board and wide-temperature hard drive. Combined with a soft-start circuit design, it can achieve a wide-range DC power supply from 18V to 36V, while maintaining a low inrush current, adapting to complex power supply environments. Simultaneously, through a DC filter design, it can achieve DC power supply electromagnetic interference (EMI) filtering, suppress high-frequency signals, and improve the electromagnetic compatibility indicators related to power line conduction.

[0069] Furthermore, in some embodiments, the video storage device may further include:

[0070] The ruggedized chassis houses the video recorder 20, wide-temperature hard disk 30, DC filter 50, soft-start circuit 40, and isolated power supply module 60. The first aviation socket and the second aviation socket are located on the front panel of the ruggedized chassis.

[0071] In this embodiment, the video storage device further includes a ruggedized chassis.

[0072] The aforementioned video recorder 20, wide-temperature hard disk 30, soft-start circuit 40, DC filter 50 and isolated power supply module 60 are all deployed inside the ruggedized chassis, and the first aviation socket and the second aviation socket are both deployed on the front panel of the ruggedized chassis.

[0073] Furthermore, in some embodiments, the reinforced chassis is made of rust-resistant aluminum, the inner surface of the reinforced chassis is conductively anodized, and the connection points of the reinforced chassis are made of three-dimensional concave contact.

[0074] In this embodiment, the reinforced chassis is made of rust-proof aluminum, the inner surface of the reinforced chassis is conductively anodized, and the connection points of the reinforced chassis are made of three-dimensional concave contact to enhance the shielding effect.

[0075] In addition, the outer surface of the reinforced chassis is coated with multiple layers of primer, intermediate paint and topcoat; the front panel of the reinforced chassis is equipped with an external aviation socket and a switch with lights, and cables are laid on the floor inside the reinforced chassis.

[0076] In this embodiment, the ruggedized chassis adopts grounding isolation design, power isolation design, cable shielding and twisted pair design, cabling optimization design and electrical continuity design, which improves electromagnetic compatibility performance and has good electromagnetic compatibility, enabling the video storage device to work stably in complex electromagnetic environments.

Specifically, the USB port of the recording board 20 connects to the peripherals via an internal USB cable and the fourth aviation socket.

[0088] In this embodiment, the wide-temperature hard disk 30, video recorder 20, isolated power supply module 60, DC filter 50 and soft-start circuit 40 all have a three-proof design (proof against moisture and heat, anti-mold and anti-salt spray). At the same time, the reinforced chassis improves the overall three-proof performance (proof against moisture and heat, anti-mold and anti-salt spray) of the video storage device through structural sealing design, aviation socket sealing design and external protective coating design.
