In computer monitoring systems, the FPGA-based image dynamic storage device is usually used for high-speed video acquisition and real-time processing. It can receive the video stream from the monitoring camera and quickly store the image data in the internal memory for subsequent processing and analysis. The existing computer monitoring system storage device (Announcement No.: CN214954949U) has the following disadvantages in use:

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In computer monitoring systems, FPGA image dynamic storage devices are usually used for high-speed video acquisition and real-time processing. It can receive video streams from monitoring cameras and quickly store image data in internal memory for subsequent processing and analysis. The FPGA image dynamic storage device provided by the utility model is specifically used to receive video streams from monitoring cameras and quickly store image data in internal memory. In the process of using this device, it is necessary to ensure that the motor 905 and the cooling plate 4 can work normally in advance, so as to ensure the normal operation of the device.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an image dynamic storage device based on FPGA, comprising a bottom shell 1, a chip is installed on the inner wall of the bottom end of the bottom shell 1, an upper shell 2 is installed on the top of the bottom shell 1, a connecting plate 16 is fixed to the inner wall of the upper shell 2, a mounting opening is provided on the top of the connecting plate 16, a thermal pad 15 is fixed in the mounting opening, a heat sink 5 is fixed on the top of the thermal pad 15, a heat pipe 6 is installed in the heat sink 5, a plurality of connecting holes 12 are provided on one side of the heat sink 5, a connecting column 7 is fixed between the inner walls at both ends of the upper shell 2, a sliding member 10 is slidably connected to the connecting column 7, a fan 8 is fixed on one side of the sliding member 10, and a moving mechanism 9 is provided on the inner wall at the top of the upper shell 2. The moving mechanism 9 includes a first rotating shaft 902 and a second rotating shaft rotatably connected to the inner wall of the top end of the upper shell 2, the outer walls of the first rotating shaft 902 and the second rotating shaft are fixed with a first gear 901, the two first gears 901 are meshed with each other, the outer walls of the first rotating shaft 902 and the second rotating shaft are fixed with a second gear 903, the second gear 903 is a missing gear, a rack 904 is fixed on the other side of the slide 10, the second gear 903 is meshed with the rack 904, a motor 905 is fixed to the top end of the upper shell 2, and the output end of the motor 905 passes through the upper shell 2 and is fixed to the top end of the first rotating shaft 902.

[0021] It should be noted that the chip is contacted through the thermal pad 15, and then the heat is dissipated through the heat sink 5. After that, the cold water in the heat pipe 6 circulates to dissipate the heat on the heat sink 5, and takes away the heat on the heat sink 5. The fan 8 moves so that the heat on the heat sink 5 can be better taken away by the heat pipe 6, and the air in the upper shell 2 can be more circulated, so that the chip heat dissipation can be more sufficient. The fan 8 moves through the motor 905 to drive the first shaft 902 to rotate. The rotation of the first shaft 902 drives one of the first gears 901 to rotate. The rotation of this first gear 901 drives the other first gear 901 to rotate, so that the second shaft rotates, thereby rotating the two second gears 903. When one of the two second gears 903 rotates to mesh with the rack 904, it drives the rack 904 to move to the left, and when the other rotates to mesh with the rack 904, it drives the rack 904 to move to the right. In this way, the rack 904 drives the fan 8 to repeatedly move left and right.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, a refrigeration box 3 is fixed between the inner walls on both sides of the upper shell 2, and a plurality of refrigeration fins 4 are provided through one end of the refrigeration box 3. A cooling fan is installed at one end of the refrigeration fin 4 outside the refrigeration box 3. Both ends of the heat dissipation pipe 6 are fixedly connected with the refrigeration box 3. Two water pumps are installed in the refrigeration box 3. One end of the heat dissipation pipe 6 is fixedly connected with the water inlet of one of the water pumps, and the other end of the heat dissipation pipe 6 is fixedly connected with the water outlet of the other water pump. An air inlet is provided on one side of the upper shell 2, and a heat dissipation hole 11 is provided on the other side of the upper shell 2. Mounting plates are fixed on both sides of the bottom shell 1 and both sides of the upper shell 2, and two adjacent mounting plates are fixed by bolts. A connecting member 13 is fixed on the inner wall at the top of the upper shell 2, and a sliding block is fixed on the top of the sliding member 10. The sliding block slides in the connecting member 13. A mounting frame 14 is installed on the inner wall at the bottom end of the bottom shell 1, and the chip is located in the mounting frame 14.

[0023] It should be noted that the cooling plate 4 is made of semiconductor material, one side of which absorbs heat to make it cold, while the other side releases heat to make it hot, wherein the cold side is located in the refrigeration box 3, and the hot side dissipates heat through the cooling fan. In addition, two water pumps are set to circulate the water in the heat pipe 6.

[0024] Working principle: When the chip needs to be cooled, it is contacted with the chip through the thermal pad 15, and then the heat is dissipated through the heat sink 5. After that, the two water pumps are set to circulate the water in the heat sink 6. The heat sink 6 allows the cold water in the heat sink 6 to circulate to dissipate the heat of the heat sink 5 and take away the heat on the heat sink 5. The fan 8 is moved through the moving mechanism 9 so that the heat on the heat sink 5 can be better taken away by the heat sink 6.
