Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an optical gateway device. Background Art

[0002] Currently, some scenarios, such as street shops and commercial buildings, require the use of cameras.

[0003] In related technologies, the network system in which a camera resides includes the camera, a fiber-to-the-room (FTTR) gateway device, and a network video recorder (NVR). Video captured by the camera can be transmitted to the NVR via the FTTR gateway device for storage. Furthermore, the NVR can be connected to a monitor to display the video captured by the camera.

[0004] However, in the above network system, it is not convenient for operators to uniformly manage (such as installation, acceptance and maintenance) FTTR gateway devices and NVRs. Utility Model Content

[0005] The present disclosure provides an optical gateway device. The optical gateway device integrates the functions of a network video recorder (NVR). The technical solution of the optical gateway device is as follows.

[0006] The present disclosure provides an optical gateway device. The optical gateway device includes a housing, a partition, a gateway module, and an NVR module. The NVR module includes a video storage module. The partition is located within the housing and divides the interior of the housing into a first chamber and a second chamber. The gateway module is located in the first chamber, and the video storage module is located in the second chamber.

[0007] Optical gateway devices are fiber-to-the-room (FTTR) gateways or optical network terminal (ONT) gateways. Gateway modules implement network uplink and downlink, forwarding, and wireless local area network (WLAN) signal coverage. NVR modules implement functions such as video encoding and decoding, recording, storage, and display (output to a monitor). Within the NVR module, the video storage module is used to store videos. The video storage module is a heat-sensitive component.

[0008] The technical solution provided by the present disclosure provides an optical gateway device including a gateway module and an NVR module, so that the optical gateway device has the functions of both a gateway and an NVR. The video captured by the camera is first transmitted to the gateway module, and then the gateway module transmits the video to the NVR module for storage. In addition, the NVR module can also be connected to a display to display the video captured by the camera on the display. This is beneficial to the operator's management of the optical gateway device. In addition, by providing a partition to divide the interior of the shell into a first chamber and a second chamber, and arranging the gateway module in the first chamber and the video storage module in the second chamber, the influence of the heat emitted by the gateway module on the video storage module is reduced, thereby improving the reliability of the video storage module.

[0009] In one implementation, the first and second chambers are stacked along the height of the optical gateway. This increases the height of the optical gateway but reduces its footprint, or more accurately, the desktop area occupied by the optical gateway, facilitating its placement on the desktop.

[0010] In one implementation, the first chamber is located above the second chamber. This position of the second chamber adjacent to the bottom of the housing facilitates the provision of heat dissipation holes at the bottom of the housing that connect to the second chamber, thereby facilitating heat dissipation from the video storage module. Furthermore, the heat dissipation holes at the bottom of the housing are invisible, enhancing the aesthetics of the optical gateway device.

[0011] In one implementation, the NVR module further includes a video processing module located in the second chamber. The video processing module is used to implement functions such as video encoding and decoding, recording, and display (outputting to a display).

[0012] In one implementation, the gateway module includes a main chip and a first heat sink, which is attached to the main chip. The video processing module is located below the first heat sink, and the video storage module is offset from the first heat sink. This maximizes the distance between the video storage module and the first heat sink or main chip, further reducing the impact of heat dissipated by the gateway module on the video storage module and improving the reliability of the video storage module. The main chip is the primary heat source in the gateway module.

[0013] In one implementation, the partition further divides the second chamber into a first sub-chamber and a second sub-chamber arranged horizontally. The video processing module is located in the first sub-chamber, and the video storage module is located in the second sub-chamber. This reduces the impact of heat dissipated by the video processing module on the video storage module, further lowering the temperature of the video storage module and improving its reliability.

[0014] In one implementation, the bottom of the housing includes a first heat dissipation hole and a foot pad. The first heat dissipation hole connects the second chamber to the outside world. The foot pad is used to elevate the plane where the first heat dissipation hole is located. When the optical gateway device is placed on a support surface such as a desktop, the foot pad provides support, creating a gap between the bottom of the housing and the support surface. External air can flow into the second chamber through this gap and the first heat dissipation hole, achieving air cooling for the video storage module.

[0015] In one implementation, the video storage module includes a hard drive and a heat sink, which is positioned below the hard drive. The bottom of the housing includes two sets of first heat dissipation holes, which are positioned on either side of the heat sink. The hard drive is a heat-sensitive component. Air entering the second chamber through the first heat dissipation holes flows through the heat sink, removing heat from the heat sink, thereby lowering the temperature of the heat sink and, in turn, the hard drive.

[0016] In one implementation, the video storage module includes a hard drive and a hard drive bay. The housing includes an opening that communicates with one end of the hard drive bay. The hard drive can be inserted and removed from the bay through the opening. This facilitates hard drive replacement in the optical gateway device.

[0017] In one implementation, the optical gateway device further includes a panel that is detachably connected to the housing and serves to cover the opening. A second heat dissipation hole is provided between the panel and the housing, connecting the opening to the outside world. This allows air from the outside to flow into the hard drive bay through the second heat dissipation hole and the opening, removing heat from the hard drives.

[0018] In one implementation, the second heat dissipation hole is located on the bottom side of the panel or housing and faces downward. This facilitates air intake through the second heat dissipation hole. Furthermore, the second heat dissipation hole is not exposed, making the optical gateway device more aesthetically pleasing.

[0019] In one implementation, the video storage module further includes a backplane located at an end of the hard drive bay away from the opening. The backplane is used to dock with the hard drive and enable external connections to the hard drive. The backplane includes a slot that connects to the interior of the hard drive bay. The backplane is used to dock with the video processing module or gateway module. External air can flow into the interior of the hard drive bay through the second heat dissipation holes and the opening, and then out of the hard drive bay through the slot, achieving front-to-back ventilation for the hard drive or hard drive bay.

[0020] In one implementation, a third heat dissipation hole is included on the wall of the housing opposite to the back plate, wherein air inside the hard disk bay flows out through the slots of the back plate and then flows out to the outside of the optical gateway device through the third heat dissipation hole.

[0021] In one implementation, the end of the hard disk near the opening includes a locking member and a handle bar. The locking member is used to lock the handle bar, and when the locking member is unlocked by the user, the handle bar pops open. The video storage module also includes a transmission member and a power-off protection trigger member. One end of the transmission member is transmission-connected to the locking member or the handle bar, and the other end is used to touch the power-off protection trigger member. When the locking member is unlocked, the locking member or the handle bar drives the transmission member to touch the power-off protection trigger member, so that the power-off protection trigger member instructs the gateway module or the video processing module to perform a power-off protection operation on the hard disk. The power-off protection operation includes stopping read and write operations on the hard disk and actively powering off the hard disk.

[0022] The technical solution provided by the present disclosure requires that before the user pulls out the hard drive, the user must first unlock the locking member, causing the handle to pop open. Only then can the user grasp the handle and pull it outward to remove the hard drive from the optical gateway device. The present disclosure sets a transmission member that is linked to the locking member or the handle, so that when the user unlocks the locking member, the locking member or the handle will drive the transmission member to contact the power-off protection trigger member. This ensures that the gateway module or video processing module has completed the power-off protection operation before the user pulls out the hard drive, and the hard drive will not be damaged.

[0023] In one implementation, the video storage module also includes a backplane located at the end of the hard drive bay away from the opening. The backplane is used to dock the hard drive and enable external connections. A power-off protection trigger is located on the backplane. This facilitates the power-off protection trigger sending an indication message to the gateway module or video processing module.

[0024] In one implementation, the transmission member includes a first rod and a second rod bent to each other, wherein the first rod is connected to the locking member or the handle bar, and the second rod is used to contact the power-off protection trigger member.

[0053] Currently, certain scenarios, such as street-side shops and commercial buildings, require the use of cameras. These cameras are typically used in conjunction with a network video recorder (NVR). The camera communicates with the NVR, allowing the video it captures to be transmitted to the NVR for storage. Furthermore, the NVR can be connected to a monitor to display the video captured by the camera.

[0054] In some scenarios, for example, if the camera is a wireless camera, or the camera is too far away from the NVR, or there are too many cameras, the camera needs to be connected to the NVR through a gateway device (for example, a fiber to the room (FTTR) gateway device). Figure 11 is a schematic diagram of a network system composed of a camera 100, a FTTR gateway device 200 and an NVR 300 in the related art. Figure 1 As shown, the camera 100 is connected to the FTTR gateway device 200 for communication, and the FTTR gateway device 200 is connected to the NVR 300 for communication. The video captured by the camera 100 can be transmitted to the NVR 300 via the FTTR gateway device 200. Figure 1 In the embodiment, multiple cameras are connected to the NVR 300 through a single-stage FTTR gateway device 200. In actual applications, cameras can also be connected to the NVR 300 through multiple stages of FTTR gateway devices 200. The multiple stages of FTTR gateway devices 200 are cascaded.

[0055] In the above network system, the FTTR gateway device 200 and the NVR 300 are independent of each other, which is not conducive to the operator's unified management (installation, acceptance and maintenance). In addition, the separate FTTR gateway device 200 and NVR 300 occupy a large space.

[0056] In view of the above technical problems, the embodiments of the present disclosure provide a novel network system including a camera. Figure 2 Figure 2 is a schematic diagram of a network system comprising a camera 100 and an FTTR gateway device 200, according to an embodiment of the present disclosure. The FTTR gateway device 200 integrates the functionality of an NVR 300. After the camera 100 sends video to the FTTR gateway device 200, the FTTR gateway device 200 can store the video. Furthermore, the FTTR gateway device 200 can be connected to a display 400 to display the video captured by the camera 100.

[0057] It should be noted that the FTTR gateway device 200 integrates the functions of the NVR 300, which can also be understood as the NVR 300 integrating the functions of the FTTR gateway device 200. Therefore, the FTTR gateway device 200 provided in the embodiment of the present disclosure can also be called NVR 300, a FTTR gateway and NVR integrated device, or a FTTR gateway and NVR all-in-one device.

[0058] The following is a more detailed exemplary description of the FTTR gateway device 200 provided in the embodiment of the present disclosure. Figure 3 is a schematic diagram of an FTTR gateway device 200. Figure 4 This is a schematic diagram of the FTTR gateway device 200 with the panel 5 hidden. Figure 5 FIG. 2 is a schematic diagram of the back side of the FTTR gateway device 200 . Figure 6 FIG. 2 is an exploded view of the FTTR gateway device 200 .

[0059] In some examples, such as Figure 6 As shown, FTTR gateway device 200 includes a housing 1 (comprising a base housing 11 and a top cover 12), a gateway module 3, and an NVR module 4. Both modules are located within housing 1. Gateway module 3 is used to implement FTTR gateway device functions, such as network uplink and downlink forwarding and wireless local area network (WLAN) signal coverage. NVR module 4 is used to implement functions such as video encoding and decoding, recording, storage, and display (outputting to display 400).

[0060] The video captured by camera 100 is first transmitted to gateway module 3. Gateway module 3 then transmits the video to NVR module 4, which stores the video and can output it to display 400 for display. This shows that by placing gateway module 3 and NVR module 4 within the same housing 1, the disclosed embodiment achieves the integration of FTTR gateway devices and NVRs, reducing the number of devices required in a user's room. This also facilitates unified management for operators.

[0061] In some examples, such as Figure 6 As shown, the NVR module 4 includes a video processing module 41 and a video storage module 42. Among them, the video processing module 41 is used to realize the functions of video encoding and decoding, recording, and outputting the video to the display 400 for display. The video storage module 42 is used to store the video. The video processing module 41 is communicatively connected to the gateway module 3, and the video storage module 42 is communicatively connected to the video processing module 41. The video captured by the camera 100 is first transmitted to the gateway module 3, and then the gateway module 3 transmits the video to the video processing module 41. After the video processing module 41 processes the video, the video is transmitted to the video storage module 42 for storage. In addition, the video processing module 41 can also be connected to the display 400 to output the video to the display 400 for display.

[0062] The following is an exemplary description of the implementation of the gateway module 3 , the video processing module 41 , and the video storage module 42 .

[0063] Figure 7 Schematic diagram of the gateway module 3 is shown. In some examples, such as Figure 7As shown, the gateway module 3 includes a first circuit board 31, a main chip (not shown in the figure, blocked by the first heat sink 32), a photoelectric conversion device 33 and an optical interface component 34. The optical interface component 34 is optically connected to the photoelectric conversion device 33, and the photoelectric conversion device 33 is electrically connected to the main chip. In the light receiving direction, the optical interface component 34 sends the received optical signal to the photoelectric conversion device 33, the photoelectric conversion device 33 converts the optical signal into an electrical signal, and sends the electrical signal to the main chip. The main chip is used to perform corresponding processing on the electrical signal, and can also send the processed electrical signal (in this case, the electrical signal corresponding to the video) to the video processing module 41. In the light sending direction, the main chip sends the electrical signal to the photoelectric conversion device 33, the photoelectric conversion device 33 converts the electrical signal into an optical signal, and sends the optical signal to the outside through the optical interface component 34.

[0064] The main chip is the component with the highest power consumption in the gateway module 3. Therefore, the gateway module 3 further includes a first heat sink 32, which is attached to the main chip to improve the heat dissipation efficiency of the main chip.

[0065] In some examples, such as Figure 7 As shown, the gateway module 3 also includes a network cable interface component 35, which is used to connect to the network cable and send electrical signals transmitted by the network cable to the main chip, or send electrical signals transmitted by the main chip to the network cable. The camera 100 can be connected to the gateway module 3 via the optical interface component 34 or the network cable interface component 35.

[0066] In some examples, such as Figure 7 As shown, the gateway module 3 also includes a power interface component 36 and a power button 37. The power interface component 36 is used to connect to the power cord, which is used to power the gateway module 3 and can also be used to power the NVR module 4. The power button 37 is used to control the stop and start of power supply to realize the power on and off of the FTTR gateway device 200.

[0067] It should be noted that in some examples, such as Figure 5 As shown, the optical interface component 34 , the network cable interface component 35 , the power interface component 36 and the power button 37 are exposed on the back of the FTTR gateway device 200 .

[0068] In some examples, such as Figure 3-Figure 5 As shown, in order to realize the function of wireless LAN signal coverage of the gateway module 3, the FTTR gateway device further includes an antenna 6, which is electrically connected to the gateway module 3 and is located outside the housing 1. In some examples, such as Figure 3-Figure 5 As shown, there are four antennas 6 .

[0069] Figure 8 Schematic diagram of the video processing module 41 is shown. In some examples, such as Figure 8 As shown, the video processing module 41 includes a second circuit board 411 and a video processing chip (not shown in the figure, blocked by the second radiator 412). The video processing chip is used to be electrically connected to the gateway module 3 and to process the video signal transmitted by the gateway module 3 (for example, codec processing). The video processing chip is the component with the highest power consumption in the video processing module 41. Therefore, in some examples, the video processing module 41 also includes a second radiator 412, which is attached to the video processing chip to improve the heat dissipation efficiency of the video processing chip.

[0070] In some examples, such as Figure 8 As shown, the video processing module 41 further includes a video output interface component 413 , which is used to connect to the display 400 to output the video signal to the display 400 for display.

[0071] In some examples, such as Figure 8 As shown, the video processing module 41 further includes an external device interface component 414, which is used to connect external devices, such as a mouse, so that the user can control the display content of the display 400 by operating the mouse.

[0072] It should be noted that in some examples, such as Figure 5 As shown, the video output interface component 413 and the peripheral interface component 414 are exposed on the back of the FTTR gateway device 200.

[0073] Figure 9 Schematic diagram of the video storage module 42 is shown. In some examples, such as Figure 9 As shown, the video storage module 42 includes a hard disk 421, which is electrically connected to the video processing module 41 to receive and store the video sent by the video processing module 41. The hard disk 421 can be a solid-state disk / solid-state drive (SSD) or a hard disk drive (HDD).

[0074] In some examples, the hard disk 421 is fixed in the housing 1. In other examples, the hard disk 421 is provided in the housing 1 in a pluggable manner. Figures 9-11 As shown, the video storage module 42 further includes a hard disk bay 422, and the hard disk 421 can be plugged in and out of the hard disk bay 422. Figure 4 As shown, an opening 113 is provided in the corresponding portion of the housing 1, and the opening 113 is connected to one end of the hard disk compartment 422. In addition, in order to block the opening 113, as shown in FIG. Figure 3 、 Figure 4 and Figure 6As shown, the FTTR gateway device 200 further includes a panel 5, which is detachably connected to the housing 1 and is used to cover the opening 113. The panel 5 can be connected to the housing 1 by magnetic attraction. The panel 5 can be located on the front side of the FTTR gateway device 200.

[0075] In some examples, such as Figure 9 As shown, the end of the hard drive 421 near the opening 113 includes a locking member 4211 and a handle 4212. The locking member 4211 is used to lock the handle 4212, and when the locking member 4211 is unlocked by the user, the handle 4212 pops open. The user can then pull out the hard drive 421 by holding the handle 4212.

[0076] In addition, the hard disk 421 is a heat-sensitive component. In addition, the hard disk 421 and the high-energy-consuming gateway module 3 are placed inside the same housing 1. Therefore, the hard disk 421 requires a stronger heat dissipation capability. Figures 9-11 As shown, the video storage module 42 further includes a heat sink substrate 423, which is located below the hard disk 421. Specifically, if the video storage module 42 includes a hard disk bay 422, the heat sink substrate 423 is located below the hard disk bay 422 and is attached to the hard disk bay 422. If the video storage module 42 does not include a hard disk bay 422, the heat sink substrate 423 can be directly attached to the hard disk 421. In some examples, the heat sink substrate 423 is an aluminum substrate.

[0077] To achieve communication between the hard disk 421 and the video processing module 41, in some examples, such as Figures 9-11 As shown, the video storage module 42 also includes a backplane 424, which is located at the end of the hard disk bay 422 away from the opening 113. The backplane 424 is used to dock with the hard disk 421 to provide an electrical connection thereto. Furthermore, the backplane 424 is also used to electrically connect the hard disk 421 to the video processing module 41 and to the gateway module 3.

[0078] In some examples, a first connector is provided on the side of the hard drive 421 facing the backplane 424, and a second connector is provided on the side of the backplane 424 facing the hard drive 421. When the hard drive 421 is inserted into the hard drive bay 422, the first connector mates with the second connector to establish an electrical connection between the hard drive 421 and the backplane 424. In addition, other connectors are provided on the backplane 424 for connecting to the video processing module 41 or the gateway module 3.

[0079] The technical solution provided by the disclosed embodiments places the gateway module 3 and NVR module 4 within the same housing 1, which may increase the size of the FTTR gateway device 200. Furthermore, the heat source of the gateway module 3 (i.e., the main chip) can also affect the reliability of the hard disk 421 of the NVR module 4. Therefore, how to properly arrange the gateway module 3 and NVR module 4 within the housing 1 to reduce the footprint of the FTTR gateway device 200 and improve the heat dissipation efficiency of the hard disk 421 is a key technical issue.

[0080] The following is an exemplary description of the arrangement of the gateway module 3 and the NVR module 4 in the housing 1 .

[0081] Figure 12 The internal structure diagram of the first FTTR gateway device is shown. Figure 12 As shown, the FTTR gateway device further includes a partition 2, which is located within the housing 1 and divides the interior of the housing 1 into a first chamber 101 and a second chamber 102, and divides the second chamber 102 into a first sub-chamber 1021 and a second sub-chamber 1022. The gateway module 3 is located in the first chamber 101. The video processing module 41 is located in the first sub-chamber 1021, and the video storage module 42 is located in the second sub-chamber 1022. Thus, the gateway module 3, video processing module 41, and video storage module 42 are located in three chambers, respectively. This reduces the impact of heat generated by the gateway module 3 and video processing module 41 on the hard disk 421 in the video storage module 42, thereby improving the reliability of the hard disk 421.

[0082] Figure 13 Schematic diagram of the internal structure of the second FTTR gateway device 200 is shown. In some examples, such as Figure 13 As shown, the partition 2 divides the interior of the shell 1 into a first chamber 101 and a second chamber 102, but does not divide the second chamber 102 into a first sub-chamber 1021 and a second sub-chamber 1022. The video processing module 41 and the video storage module 42 are located in the same chamber. Among them, the main chip of the gateway module 3 is the main heat source. Therefore, by separating the gateway module 3 and the video storage module 42 in different chambers, the effect of the heat generated by the gateway module 3 on the hard disk 421 in the video storage module 42 is reduced. Among them, the heat of the video processing module 41 has a relatively small effect on the gateway module 3. Therefore, the video processing module 41 and the video storage module 42 can be set in the same chamber.

[0083] It should be noted that the video processing module 41 can also be integrated with the gateway module 3. In this case, it can also be understood that the NVR module 4 does not include the video processing module 41. Figure 14 As shown, the second chamber 102 only includes the video storage module 42 .

[0084] To achieve integration of the video processing module 41 and the gateway module 3, in some examples, the video processing module 41 includes a video processing chip, a video output interface component 413, and a peripheral interface component 414, all located on the first circuit board 31 of the gateway module 3, thereby achieving integration of the video processing module 41 and the gateway module 3. In other examples, the main chip of the gateway module 3 integrates the functions of the original video processing chip, for example, the main chip also performs encoding and decoding.

[0085] The embodiment of the present disclosure does not limit the arrangement of the first chamber 101 and the second chamber 102. In some examples, the first chamber 101 and the second chamber 102 are arranged in a horizontal direction.

[0086] In other examples, such as Figure 12-14 As shown, the first chamber 101 and the second chamber 102 are stacked along the height direction of the FTTR gateway device 200. Compared with the horizontal arrangement, this is equivalent to increasing the height of the FTTR gateway device 200, but reducing the floor space of the FTTR gateway device 200 (i.e., the desktop area occupied), which is conducive to placing the FTTR gateway device 200 on a desktop.

[0087] In some examples, such as Figure 12-14 As shown, the first chamber 101 is located above the second chamber 102. This makes it possible to provide a heat dissipation hole at the bottom of the housing 1 that connects to the second chamber 102, thereby improving the heat dissipation efficiency of the video storage module 42. Furthermore, the heat dissipation hole is not exposed, which improves the aesthetics of the FTTR gateway device 200.

[0088] In some examples, such as Figure 12-14 As shown, the video processing module 41 is located below the first heat sink 32, and the video storage module 42 is staggered with the first heat sink 32. In this way, the video storage module 42 is as far away from the heat source as possible (i.e., the main chip attached to the first heat sink 32), which helps to reduce the temperature of the video storage module 42 and improve the reliability of the video storage module 42.

[0089] Figure 15 Shown Figure 12 Schematic diagram of the partition 2 in FIG. In some examples, such as Figure 15 As shown, the partition 2 includes a transverse partition 21 and a vertical partition 22. The transverse partition 21 is arranged horizontally and divides the interior of the shell 1 into a first chamber 101 and a second chamber 102 arranged in a stacked manner along the height direction. The vertical partition 22 is located in the second chamber 102 and divides the second chamber 102 into a first sub-chamber 1021 and a second sub-chamber 1022 arranged horizontally. Figure 13 and Figure 14 The partition 2 in the figure does not include the vertical partition 22.

[0090] In some examples, such as Figure 15 As shown, the vertical partition 22 extends in the front-to-back direction, and the first sub-chamber 1021 and the second sub-chamber 1022 are arranged in the left-to-right direction.

[0091] In some examples, such as Figure 15 As shown, the partition 2 further includes a first side plate 23 and a second side plate 24. The first side plate 23, the second side plate 24, the vertical partition plate 22 and the horizontal partition plate 21 form a first sub-chamber 1021. The second side plate 24 is disposed opposite to the vertical partition plate 22.

[0092] In some examples, such as Figure 15 As shown, the second side plate 24 is provided with a fifth heat dissipation hole 241. Figure 12-14 As shown, a fourth heat dissipation hole 115 is provided on the wall of the housing 1 opposite the second side plate 24, and the fourth heat dissipation hole 115 is connected to the outside of the housing 1. In this way, the interior of the first sub-chamber 1021 is connected to the outside through the fifth heat dissipation hole 241 and the fourth heat dissipation hole 115, achieving natural air cooling and heat dissipation of the video processing module 41.

[0093] In some examples, such as Figure 15 The partition 2 further includes a third side plate 25, which is disposed opposite to the vertical partition 22. A second sub-chamber 1022 is defined between the vertical partition 22 and the third side plate 25.

[0094] In some examples, such as Figure 15 As shown, the third side plate 25 is a frame structure. Figure 12-14 As shown, a fourth heat dissipation hole 115 is formed on the wall of the housing 1 opposite the third side plate 25, and the fourth heat dissipation hole 115 is connected to the outside of the housing 1. In this way, the interior of the second sub-chamber 1022 is connected to the outside through the hollow portion of the third side plate 25 and the fourth heat dissipation hole 115, achieving natural air cooling and heat dissipation of the video storage module 42.

[0095] Figure 16 Schematic diagram of the bottom of the FTTR gateway device 200 is shown. In some examples, such as Figure 16 As shown, the bottom of the housing 1 includes a first heat dissipation hole 111 and a foot pad 112. The first heat dissipation hole 111 communicates with the second chamber 102. The foot pad 112 is used to elevate the plane where the first heat dissipation hole 111 is located. Thus, when the FTTR gateway device 200 is placed on a desktop, the foot pad 112 creates a gap between the bottom wall of the housing 1 and the desktop. Air can enter the interior of the second chamber 102 through this gap and the first heat dissipation hole 111, achieving natural air cooling of the video storage module 42.

[0096] Figure 17 Schematic diagram showing the relative positions of the heat dissipation substrate 423 and the first heat dissipation hole 111. In some examples, such as Figure 17 As shown, the bottom of the housing 1 includes two groups of first heat dissipation holes 111, which are arranged on both sides of the heat dissipation substrate 423. In this way, the air entering through the first heat dissipation holes 111 can flow through the heat dissipation substrate 423 to dissipate the heat of the heat dissipation substrate 423.

[0097] In some examples, such as Figure 16 、 Figure 18 and Figure 19 As shown, there is a second heat dissipation hole 51 between the panel 5 and the housing 1, and the second heat dissipation hole 51 connects the opening 113 to the outside. In this way, air can enter the interior of the hard disk compartment 422 through the second heat dissipation hole 51 and the opening 113 to achieve heat dissipation for the hard disk 421.

[0098] In some examples, such as Figure 16 and Figure 18 As shown, the second heat dissipation hole 51 is located on the bottom side of the panel 5 and the housing 1 and faces downward. In this way, the second heat dissipation hole 51 is not visually exposed, making the FTTR gateway device 200 more beautiful.

[0099] In some examples, such as Figure 3 and Figure 4 As shown, a step structure 116 is provided below the panel 5 of the housing 1 .

[0100] In some examples, such as Figure 11 and Figure 19 As shown, the back panel 424 includes a slot 4241, which is connected to the interior of the hard disk bay 422. Figure 19 As shown, the wind flows into the interior of the hard disk bay 422 through the second heat dissipation hole 51 and the opening 113, then flows through the hard disk 421, and flows out of the hard disk bay 422 through the slot 4241 on the back panel 424, achieving the effect of front-to-back ventilation of the hard disk bay 422.

[0101] In some examples, such as Figure 19 and Figure 4 As shown, the wall of the housing 1 opposite to the back plate 424 includes a third heat dissipation hole 114. In this way, the wind flowing out of the slot 4241 can flow out through the third heat dissipation hole 114. Wherein, illustratively, the third heat dissipation hole 114 is located on the back plate and the back side of the housing 1.

[0102] It should be noted that if the hard disk 421 is pulled out during the video processing module 41 reading and writing operations on the hard disk 421, the hard disk 421 may be damaged. In order to reduce the possibility of damage to the hard disk 421, in some examples, such as Figure 20As shown, the video storage module 42 also includes a transmission member 425 and a power-off protection trigger member 426. One end of the transmission member 425 is connected to the locking member 4211 or the handle bar 4212 (the handle bar 4212 is shown in the figure), and the other end is used to contact the power-off protection trigger member 426. Figure 20 As shown, when locking member 4211 is unlocked (unlocked by pressing in the figure), locking member 4211 or handle bar 4212 drives transmission member 425 to contact power-off protection trigger 426, so that power-off protection trigger 426 instructs the video processing module 41 in gateway module 3 or NVR module 4 to perform power-off protection operation on hard disk 421. Power-off protection trigger 426 can be a micro switch. The power-off protection operation includes stopping data read and write operations on hard disk 421 and actively powering off hard disk 421.

[0103] The technical solution provided by the disclosed embodiment requires that the user unlock the locking member 4211 before unplugging the hard disk 421, causing the handle 4212 to pop open. Therefore, by providing a transmission member 425 that is linked to the locking member 4211 or the handle 4212, when the user unlocks the locking member 4211, the locking member 4211 or the handle 4212 will drive the transmission member 425 to contact the power-off protection trigger 426. This ensures that the gateway module 3 or the video processing module 41 has already executed the power-off protection operation before the user unplugs the hard disk 421, preventing damage to the hard disk 421.

[0104] In some examples, such as Figure 20 As shown, the power-off protection trigger 426 is located on the back panel 424. In this way, it is convenient for the power-off protection trigger 426 to send a message to the video processing module 41 or the gateway module 3 to instruct the power-off protection operation.

[0105] In some examples, such as Figure 20 As shown, the transmission member 425 includes a first rod 4251 and a second rod 4252 that are bent together. The first rod 4251 is connected to the locking member 4211 or the handle bar 4212, and the second rod 4252 is used to contact the power-off protection trigger 426.

[0106] In some examples, such as Figure 20 As shown, the first rod 4251 and the second rod 4252 are perpendicular to each other.

[0107] In some examples, such as Figure 20As shown, a rotational connection structure 4253 is provided at the connection between the first rod 4251 and the second rod 4252, around which the transmission member 425 can rotate. The rotational connection structure 4253 can be a rotating shaft or a rotating groove. The transmission member 425 can be rotationally connected to the hard disk bay 422 or to the housing 1. The central axis of the rotational connection structure 4253 can be parallel to the height direction of the FTTR gateway device.

[0108] It should be noted that the FTTR gateway device 200 can also be replaced with other optical gateway devices, such as an optical network terminal (ONT) gateway device. The ONT gateway device and the FTTR gateway device 200 have the same structure and location in the network system, and will not be further described here. Furthermore, the FTTR gateway device 200 can also be replaced with an electrical gateway device.

[0109] The above descriptions are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principles of the present disclosure shall be included in the scope of protection of the present disclosure.
