Description

Optical gateway device

[0001] This application claims priority to Chinese Patent Application No. 202520172265.3, filed on January 24, 2025, entitled "Optical Gateway Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to an optical gateway device. Background Technology

[0003] Currently, cameras are required in certain scenarios, such as street-front shops and office buildings.

[0004] In related technologies, the network system housing the camera includes the camera, a fiber-to-the-room (FTTR) gateway device, and a network video recorder (NVR). The video captured by the camera can be transmitted to the NVR for storage via the FTTR gateway device. Furthermore, the NVR can be connected to a display to show the video captured by the camera.

[0005] However, in the aforementioned network systems, it is inconvenient for operators to uniformly manage (such as installation, acceptance, and maintenance) FTTR gateway devices and NVRs. Summary of the Invention

[0006] This application 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 described below.

[0007] This application 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 inside 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.

[0008] The optical gateway device is either a fiber-to-the-room (FTTR) gateway or an optical network terminal (ONT) gateway. The gateway module is used to implement network uplink and downlink transmission and wireless local area network (WLAN) signal coverage. The NVR module is used to implement video encoding / decoding, recording, storage, and display (output to a monitor). Within the NVR module, the video storage module is used to store video. This video storage module is a heat-sensitive component.

[0009] The technical solution provided in this application enables the optical gateway device to function as both a gateway and an NVR by including a gateway module and an NVR module. Video captured by the camera is first transmitted to the gateway module, which then transmits the video to the NVR module for storage. Furthermore, the NVR module can be connected to a display to show the video captured by the camera. This facilitates the operator's management of the optical gateway device. Additionally, by using a partition to divide the interior of the housing into a first chamber and a second chamber, and positioning the gateway module in the first chamber and the video storage module in the second chamber, the impact of heat dissipated by the gateway module on the video storage module is reduced, thus improving the reliability of the video storage module.

[0010] In one implementation, the first and second chambers are stacked along the height of the optical gateway device. This increases the height of the optical gateway device but reduces its footprint, or in other words, reduces the desktop area occupied by the optical gateway device, making it easier to place on a desktop.

[0011] In one implementation, the first chamber is located above the second chamber. This places the second chamber adjacent to the bottom of the housing, facilitating the placement of ventilation holes at the bottom of the housing that connect to the second chamber, thus improving heat dissipation for the video storage module. Furthermore, the ventilation holes at the bottom of the housing are not visually visible, enhancing the aesthetics of the optical gateway device.

[0012] In one implementation, the NVR module further includes a video processing module located in the second chamber. The video processing module is used to perform functions such as video encoding / decoding, recording, and display (outputting to a monitor).

[0013] In one implementation, the gateway module includes a main chip and a first heat sink, with the first heat sink attached to the main chip. The video processing module is located below the first heat sink, while 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 its reliability. The main chip is the primary heat source in the gateway module.

[0014] In one implementation, the partition further divides the second chamber into a horizontally arranged first sub-chamber and a second sub-chamber. 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.

[0015] In one implementation, the bottom of the housing includes a first heat dissipation hole and feet. The first heat dissipation hole connects the second chamber to the outside. The feet are used to raise the plane containing the first heat dissipation hole. When the optical gateway device is placed on a supporting surface such as a desktop, a gap exists between the bottom of the housing and the supporting surface, supported by the feet. Outside air can flow into the interior of the second chamber through this gap and the first heat dissipation hole, achieving air cooling for the video storage module.

[0016] In one implementation, the video storage module includes a hard drive and a heat sink, with the heat sink positioned below the hard drive. The bottom of the housing includes two sets of first heat dissipation holes, arranged on both sides of the heat sink. The hard drive is a heat-sensitive component. Airflow entering the second chamber from the first heat dissipation holes passes through the heat sink and carries away its heat, thereby reducing the temperature of the heat sink and consequently lowering the temperature of the hard drive.

[0017] In one implementation, the video storage module includes a hard drive and a hard drive bay. The housing includes an opening that connects to one end of the hard drive bay. The hard drive can be inserted and removed into the hard drive bay through the opening. This facilitates hard drive replacement in the optical gateway device.

[0018] In one implementation, the optical gateway device further includes a panel detachably connected to the housing and used to cover the opening. A second ventilation hole is provided between the panel and the housing, connecting the opening to the outside. This allows outside air to flow into the hard drive bay through the second ventilation hole and the opening, carrying away heat dissipated by the hard drive.

[0019] In one implementation, the second heat dissipation vent is located on the bottom side of the panel and housing, facing downwards. This facilitates airflow into the second heat dissipation vent. Furthermore, the second heat dissipation vent is not exposed, making the optical gateway device more aesthetically pleasing.

[0020] In one implementation, the video storage module also includes a backplane located at the end of the hard drive bay furthest from the opening. The backplane is used to connect to the hard drive and enable external connectivity. The backplane includes a slot that connects to the interior of the hard drive bay. The backplane is used to connect to a video processing module or a gateway module. External airflow can enter the hard drive bay through a second ventilation hole and the opening, and then exit through the slot, achieving front-to-back ventilation for the hard drive or the hard drive bay.

[0021] In one implementation, a third ventilation hole is included on the wall opposite the back panel of the housing. Airflow from inside the hard drive bay exits through slots in the back panel and then flows out through the third ventilation hole to the outside of the optical gateway device.

[0022] In one implementation, the end of the hard drive near the opening includes a locking element and a handle. The locking element locks the handle, and the handle springs open when the user unlocks the locking element. The video storage module also includes a transmission element and a power-down protection trigger. One end of the transmission element is connected to the locking element or the handle, and the other end is used to contact the power-down protection trigger. When the locking element is unlocked, the locking element or the handle drives the transmission element to contact the power-down protection trigger, causing the power-down protection trigger to instruct the gateway module or video processing module to perform a power-down protection operation on the hard drive. The power-down protection operation includes stopping read and write operations on the hard drive and actively powering down the hard drive.

[0023] The technical solution provided in this application requires the user to unlock the locking mechanism before removing the hard drive, causing the handle to spring open. Only then can the user grasp the handle and pull outwards to remove the hard drive from the optical gateway device. This application incorporates a linkage mechanism between the locking mechanism and the handle, ensuring that during the user's unlocking process, the locking mechanism or handle drives the transmission mechanism to contact the power-down protection trigger. This ensures that the gateway module or video processing module has already completed its power-down protection operation before the user removes the hard drive, preventing damage to the hard drive.

[0024] In one implementation, the video storage module also includes a backplane located at the end of the hard drive bay furthest from the opening. The backplane is used to connect to the hard drive and enable external connectivity. A power-down protection trigger is located on the backplane. This facilitates the power-down protection trigger sending indication messages to the gateway module or video processing module.

[0025] In one implementation, the transmission component includes a first rod and a second rod that are bent at each other. The first rod is connected to a locking element or a handle bar, and the second rod is used to contact a power-off protection trigger. Attached Figure Description

[0047] Currently, in certain scenarios, such as street-front shops and office buildings, cameras are required. These cameras typically need to be used in conjunction with a network video recorder (NVR). Once the camera and NVR are connected, the video captured by the camera can be transmitted to the NVR for storage. Furthermore, the NVR can be connected to a monitor to display the video captured by the camera.

[0048] In certain scenarios, such as when the camera is a wireless camera, the camera is too far from the NVR, or there are too many cameras, the cameras need to be connected to the NVR through a gateway device (e.g., a fiber-to-the-room (FTTR) gateway device). Figure 1 is a schematic diagram of a network system consisting of a camera 100, an FTTR gateway device 200, and an NVR 300, according to related technologies. As shown in Figure 1, the camera 100 is communicatively connected to the FTTR gateway device 200, and the FTTR gateway device 200 is communicatively connected to the NVR 300. The video captured by the camera 100 can be transmitted to the NVR 300 via the FTTR gateway device 200. It should be noted that in Figure 1, multiple cameras are communicatively connected to the NVR 300 through a single-level FTTR gateway device 200. In practical applications, cameras can also be communicatively connected to the NVR 300 through multiple levels of FTTR gateway devices 200, where the multiple levels of FTTR gateway devices 200 are cascaded.

[0049] In the aforementioned network system, the FTTR gateway device 200 and NVR300 operate independently, which is not conducive to unified management (installation, acceptance, and maintenance) by the operator. Furthermore, the separate FTTR gateway device 200 and NVR300 occupy a significant amount of space.

[0050] In view of the above-mentioned technical problems, this application provides a novel network system including a camera. Figure 2 is a schematic diagram of a network system consisting of a camera 100 and an FTTR gateway device 200 according to an embodiment of this application. The FTTR gateway device 200 integrates the functions of an NVR 300, so 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 also be connected to a display 400 to display the video captured by the camera 100 on the display 400.

[0051] 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 this application embodiment can also be referred to as NVR 300, an FTTR gateway and NVR converged device, or an FTTR gateway and NVR all-in-one machine.

[0052] The FTTR gateway device 200 provided in this application embodiment will now be described in more detail. FIG3 is a schematic diagram of the FTTR gateway device 200. FIG4 is a schematic diagram of the FTTR gateway device 200 after hiding panel 5. FIG5 is a schematic diagram of the rear of the FTTR gateway device 200. FIG6 is an exploded view of the FTTR gateway device 200.

[0053] In some examples, as shown in Figure 6, the FTTR gateway device 200 includes a housing 1 (comprising a bottom shell 11 and a top cover 12), a gateway module 3, and an NVR module 4. The gateway module 3 and NVR module 4 are located inside the housing 1. The gateway module 3 implements the relevant functions of the FTTR gateway device, such as network uplink and downlink transmission and wireless local area network (WLAN) signal coverage. The NVR module 4 implements video encoding / decoding, recording, storage, and display (output to the display 400).

[0054] In this embodiment, the video captured by camera 100 is first transmitted to gateway module 3. Then, gateway module 3 transmits the video to NVR module 4, which stores the video and can output it to display on monitor 400. Thus, this embodiment achieves the integration of FTTR gateway equipment and NVR by placing gateway module 3 and NVR module 4 inside the same housing 1, reducing the number of devices users need to place in a room. It also facilitates unified management by operators.

[0055] In some examples, as shown in Figure 6, the NVR module 4 includes a video processing module 41 and a video storage module 42. The video processing module 41 performs video encoding / decoding, recording, and outputting the video to the display 400. The video storage module 42 stores 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, then the gateway module 3 transmits the video to the video processing module 41. After processing, the video processing module 41 transmits the video to the video storage module 42 for storage. Additionally, the video processing module 41 can also be connected to the display 400 to output the video for display.

[0056] The implementation methods of the gateway module 3, video processing module 41, and video storage module 42 will be illustrated below.

[0057] Figure 7 shows a schematic diagram of the gateway module 3. In some examples, as shown in Figure 7, the gateway module 3 includes a first circuit board 31, a main chip (not shown in the figure, shielded by a 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. Specifically, in the light receiving direction, the optical interface component 34 sends the received optical signal to the photoelectric conversion device 33, which converts the optical signal into an electrical signal and sends the electrical signal to the main chip. The main chip processes the electrical signal accordingly and can also send the processed electrical signal (which is the electrical signal corresponding to the video signal) to the video processing module 41. In the light transmitting direction, the main chip sends the electrical signal to the photoelectric conversion device 33, which converts the electrical signal into an optical signal and transmits the optical signal externally through the optical interface component 34.

[0058] In gateway module 3, the main chip is the component with the highest power consumption. Therefore, gateway module 3 also includes a first heat sink 32, which is attached to the main chip to improve the heat dissipation efficiency of the main chip.

[0059] In some examples, as shown in Figure 7, the gateway module 3 also includes a network cable interface component 35. The network cable interface component 35 is used to connect to a network cable and send the electrical signals transmitted by the network cable to the main chip, or send the electrical signals transmitted by the main chip to the network cable. The camera 100 can be connected to the gateway module 3 via an optical interface component 34 or a network cable interface component 35.

[0060] In some examples, as shown in Figure 7, 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 a power cord, which powers the gateway module 3 and can also power the NVR module 4. The power button 37 is used to control the power supply to stop and start, thereby turning the FTTR gateway device 200 on and off.

[0061] It should be noted that in some examples, as shown in Figure 5, 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.

[0062] In some examples, as shown in Figures 3-5, to achieve the function of wireless LAN signal coverage of gateway module 3, the FTTR gateway device also includes antenna 6. Antenna 6 is electrically connected to gateway module 3 and is located outside the housing 1. In some examples, as shown in Figures 3-5, there are four antennas 6.

[0063] Figure 8 shows a schematic diagram of the video processing module 41. In some examples, as shown in Figure 8, the video processing module 41 includes a second circuit board 411 and a video processing chip (not shown, but shielded by a second heat sink 412). The video processing chip is used for electrical connection with the gateway module 3 and for processing (e.g., encoding / decoding) the video signals transmitted by the gateway module 3. 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 heat sink 412, which is attached to the video processing chip to improve its heat dissipation efficiency.

[0064] In some examples, as shown in Figure 8, the video processing module 41 also includes a video output interface component 413, which is used to connect to the display 400 to output video signals to the display 400 for display.

[0065] In some examples, as shown in Figure 8, the video processing module 41 also includes a peripheral interface component 414 for connecting peripherals, such as a mouse. This allows the user to control the content displayed on the monitor 400 by operating the mouse.

[0066] It should be noted that in some examples, as shown in Figure 5, the video output interface component 413 and the peripheral interface component 414 are exposed on the back of the FTTR gateway device 200.

[0067] Figure 9 shows a schematic diagram of the video storage module 42. In some examples, as shown in Figure 9, the video storage module 42 includes a hard disk 421, which is electrically connected to the video processing module 41 to receive and store 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).

[0068] In some examples, the hard drive 421 is fixed within the housing 1. In other examples, the hard drive 421 is removably housed within the housing 1. Accordingly, as shown in Figures 9-11, the video storage module 42 also includes a hard drive bay 422, in which the hard drive 421 can be inserted and removed. Furthermore, as shown in Figure 4, an opening 113 is provided in a corresponding portion of the housing 1, connecting to one end of the hard drive bay 422. Additionally, to conceal the opening 113, as shown in Figures 3, 4, and 6, the FTTR gateway device 200 also includes a panel 5. The panel 5 is detachably connected to the housing 1 and serves to conceal the opening 113. The panel 5 can be magnetically attached to the housing 1. The panel 5 can be located on the front side of the FTTR gateway device 200.

[0069] In some examples, as shown in Figure 9, the end of the hard drive 421 near the opening 113 includes a locking element 4211 and a handle 4212. The locking element 4211 is used to lock the handle 4212, and when the locking element 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.

[0070] Furthermore, the hard drive 421 is a heat-sensitive component, and since it and the high-power gateway module 3 are housed within the same casing 1, the hard drive 421 requires stronger heat dissipation capabilities. In some examples, as shown in Figures 9-11, the video storage module 42 also includes a heat dissipation substrate 423, located below the hard drive 421. Specifically, when the video storage module 42 includes a hard drive bay 422, the heat dissipation substrate 423 is located below and adheres to the hard drive bay 422. When the video storage module 42 does not include a hard drive bay 422, the heat dissipation substrate 423 can be directly attached to the hard drive 421. In some examples, the heat dissipation substrate 423 is an aluminum substrate.

[0071] To enable communication between the hard disk 421 and the video processing module 41, in some examples, as shown in Figures 9-11, the video storage module 42 also includes a backplate 424, which is located at the end of the hard disk bay 422 away from the opening 113. The backplate 424 is used to dock with the hard disk 421 for electrical connection. Furthermore, the backplate 424 also enables electrical connection between the hard disk 421 and the video processing module 41, and can also enable electrical connection between the hard disk 421 and the gateway module 3.

[0072] In some examples, the side of hard drive 421 facing backplane 424 has a first connector, and the side of backplane 424 facing hard drive 421 has a second connector. When hard drive 421 is inserted into hard drive bay 422, the first connector mates with the second connector to establish an electrical connection between hard drive 421 and backplane 424. Additionally, backplane 424 also has other connectors for mates with video processing module 41 or gateway module 3.

[0073] The technical solution provided in this application embodiment places the gateway module 3 and the NVR module 4 in the same housing 1, which may increase the size of the FTTR gateway device 200. Simultaneously, the heat source (i.e., the main chip) of the gateway module 3 can also affect the reliability of the hard disk 421 of the NVR module 4. Therefore, how to reasonably arrange the gateway module 3 and the NVR module 4 inside 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.

[0074] The arrangement of the gateway module 3 and the NVR module 4 in the housing 1 will be described below as an example.

[0075] Figure 12 shows a schematic diagram of the internal structure of the first type of FTTR gateway device. In some examples, as shown in Figure 12, the FTTR gateway device also includes a partition 2 located inside the housing 1, dividing the interior of the housing 1 into a first chamber 101 and a second chamber 102. The second chamber 102 is further divided 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. In this way, the gateway module 3, the video processing module 41, and the video storage module 42 are located in three separate chambers, reducing the impact of the heat generated by the gateway module 3 and the video processing module 41 on the hard disk 421 in the video storage module 42 and improving the reliability of the hard disk 421.

[0076] Figure 13 shows a schematic diagram of the internal structure of the second type of FTTR gateway device 200. In some examples, as shown in Figure 13, the partition 2 divides the interior of the housing 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. 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 into different chambers, the impact of the heat generated by the gateway module 3 on the hard disk 421 in the video storage module 42 is reduced. The heat from the video processing module 41 has a relatively small impact on the gateway module 3; therefore, the video processing module 41 and the video storage module 42 can be located in the same chamber.

[0077] It should be noted that the video processing module 41 can also be integrated with the gateway module 3. In this case, it can be understood that the NVR module 4 does not include the video processing module 41. In this case, as shown in Figure 14, the second chamber 102 only includes the video storage module 42.

[0078] To integrate the video processing module 41 with the gateway module 3, in some examples, the video processing chip, video output interface component 413, and peripheral interface component 414 included in the video processing module 41 are mounted on the first circuit board 31 included in the gateway module 3, thus achieving integration between 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 is also used for encoding and decoding.

[0079] The embodiments of this application do 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.

[0080] In other examples, as shown in Figures 12-14, the first chamber 101 and the second chamber 102 are stacked along the height of the FTTR gateway device 200. This increases the height of the FTTR gateway device 200 compared to a horizontal arrangement, but reduces its footprint (i.e., the desktop area it occupies), making it easier to place the FTTR gateway device 200 on a desktop.

[0081] In some examples, as shown in Figures 12-14, the first chamber 101 is located above the second chamber 102. This arrangement, with the second chamber 102 adjacent to the bottom of the housing 1, facilitates the provision of heat dissipation holes at the bottom of the housing 1 that connect to the second chamber 102, thereby improving the heat dissipation efficiency of the video storage module 42. Furthermore, the concealed heat dissipation holes also enhance the aesthetics of the FTTR gateway device 200.

[0082] In some examples, as shown in Figures 12-14, the video processing module 41 is located below the first heat sink 32, while the video storage module 42 is offset from the first heat sink 32. This keeps the video storage module 42 as far away from the heat source (i.e., the main chip against which the first heat sink 32 is attached) as possible, which helps reduce the temperature of the video storage module 42 and improves its reliability.

[0083] Figure 15 shows a schematic diagram of the partition 2 in Figure 12. In some examples, as shown in Figure 15, the partition 2 includes a horizontal partition 21 and a vertical partition 22. The horizontal partition 21 is arranged horizontally and divides the interior of the housing 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. However, for the partition 2 in Figures 13 and 14, the vertical partition 22 is not included.

[0084] In some examples, as shown in Figure 15, 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.

[0085] In some examples, as shown in Figure 15, the partition 2 further includes a first side plate 23 and a second side plate 24, which together form a first sub-chamber 1021. The second side plate 24 is disposed opposite to the vertical partition 22.

[0086] In some examples, as shown in Figure 15, a fifth heat dissipation hole 241 is provided on the second side plate 24. Additionally, as shown in Figures 12-14, a fourth heat dissipation hole 115 is provided on the wall of the housing 1 opposite to the second side plate 24, and the fourth heat dissipation hole 115 connects 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 for the video processing module 41.

[0087] In some examples, as shown in Figure 15, the partition 2 also 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.

[0088] In some examples, as shown in Figure 15, the third side plate 25 has a frame structure. Additionally, as shown in Figures 12-14, a fourth heat dissipation hole 115 is provided on the wall of the housing 1 opposite to the third side plate 25, and the fourth heat dissipation hole 115 connects 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 hollowed-out portion on the third side plate 25 and the fourth heat dissipation hole 115, achieving natural air cooling for the video storage module 42.

[0089] Figure 16 shows a schematic diagram of the bottom of the FTTR gateway device 200. In some examples, as shown in Figure 16, the bottom of the housing 1 includes a first heat dissipation hole 111 and feet 112. The first heat dissipation hole 111 connects to the second chamber 102. The feet 112 are used to raise the plane containing the first heat dissipation hole 111. Thus, when the FTTR gateway device 200 is placed on a table, a gap exists between the bottom wall of the housing 1 and the table surface due to the action of the feet 112. 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.

[0090] Figure 17 shows a schematic diagram of the relative positions of the heat dissipation substrate 423 and the first heat dissipation holes 111. In some examples, as shown in Figure 17, the bottom of the housing 1 includes two sets of first heat dissipation holes 111, which are arranged on both sides of the heat dissipation substrate 423. In this way, the air entering from the first heat dissipation holes 111 can flow through the heat dissipation substrate 423 to dissipate the heat of the heat dissipation substrate 423.

[0091] In some examples, as shown in Figures 16, 18, and 19, a second heat dissipation hole 51 is provided between the panel 5 and the housing 1, which connects the opening 113 to the outside. In this way, air can enter the interior of the hard drive bay 422 through the second heat dissipation hole 51 and the opening 113 to dissipate heat from the hard drive 421.

[0092] In some examples, as shown in Figures 16 and 18, the second heat dissipation hole 51 is located on the bottom side of the panel 5 and the housing 1, and faces downwards. In this way, the second heat dissipation hole 51 is not visually exposed, making the FTTR gateway device 200 more aesthetically pleasing.

[0093] In some examples, as shown in Figures 3 and 4, a stepped structure 116 is provided below the panel 5 of the housing 1.

[0094] In some examples, as shown in Figures 11 and 19, the backplate 424 includes a slot 4241 that connects to the interior of the hard drive bay 422. Thus, as shown in Figure 19, air flows into the interior of the hard drive bay 422 through the second ventilation hole 51 and the opening 113, then flows past the hard drive 421, and finally exits the hard drive bay 422 through the slot 4241 on the backplate 424, achieving front-to-back ventilation for the hard drive bay 422.

[0095] In some examples, as shown in Figures 19 and 4, the wall of the housing 1 opposite the back plate 424 includes a third heat dissipation hole 114. This allows airflow from the slot 4241 to exit through the third heat dissipation hole 114. Exemplarily, the third heat dissipation hole 114 is located on the back plate and back side of the housing 1.

[0096] It should be noted that if the hard drive 421 is removed during read / write operations by the video processing module 41, it may be damaged. To reduce the possibility of damage to the hard drive 421, in some examples, as shown in Figure 20, the video storage module 42 also includes a transmission component 425 and a power-down protection trigger 426. One end of the transmission component 425 is connected to the locking component 4211 or the handle bar 4212 (shown as handle bar 4212 in the figure), and the other end is used to contact the power-down protection trigger 426. As shown in Figure 20, when the locking component 4211 is unlocked (shown as a press-to-unlock method in the figure), the locking component 4211 or the handle bar 4212 drives the transmission component 425 to contact the power-down protection trigger 426, so that the power-down protection trigger 426 instructs the video processing module 41 in the gateway module 3 or NVR module 4 to perform a power-down protection operation on the hard drive 421. The power-down protection trigger 426 can be a microswitch. The power-down protection operation includes stopping data read and write operations on the hard disk 421 and actively powering down the hard disk 421.

[0097] The technical solution provided in this application embodiment requires the user to unlock the locking member 4211 before removing the hard drive 421, causing the handle bar 4212 to spring open. Therefore, by setting a transmission member 425 that links the locking member 4211 or the handle bar 4212, during the user's unlocking process, the locking member 4211 or the handle bar 4212 will drive the transmission member 425 to contact the power-off protection trigger member 426. This ensures that the gateway module 3 or the video processing module 41 has already completed the power-off protection operation before the user removes the hard drive 421, thus preventing damage to the hard drive 421.

[0098] In some examples, as shown in Figure 20, the power-down protection trigger 426 is located on the backplane 424. This facilitates the power-down protection trigger 426 in sending a message instructing the video processing module 41 or the gateway module 3 to perform a power-down protection operation.

[0099] In some examples, as shown in Figure 20, the transmission element 425 includes a first rod 4251 and a second rod 4252 that are bent at each other. The first rod 4251 is connected to a locking element 4211 or a handle bar 4212, and the second rod 4252 is used to trigger a power-off protection trigger 426.

[0100] In some examples, as shown in Figure 20, the first rod 4251 and the second rod 4252 are perpendicular to each other.

[0101] In some examples, as shown in Figure 20, a rotating connection structure 4253 is provided at the connection between the first rod 4251 and the second rod 4252, allowing the transmission component 425 to rotate around the rotating connection structure 4253. The rotating connection structure 4253 can be a rotating shaft or a rotating groove, etc. The transmission component 425 can be rotatably connected to the hard disk drive bay 422 or to the housing 1. The central axis of the rotating connection structure 4253 can be parallel to the height direction of the FTTR gateway device.

[0102] It should be noted that the FTTR gateway device 200 described above can also be replaced with other optical gateway devices, such as optical network terminal (ONT) gateway devices. The structure and location in the network system of the ONT gateway device and the FTTR gateway device 200 can be the same, and will not be described in detail here. In addition, the FTTR gateway device 200 described above can also be replaced with an electrical gateway device.

[0103] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this application should be included within the protection scope of this application.
