Description

Technical Field

[0001] The present invention relates to the technical field of audio and video transmission, and in particular to a rack-type media network management platform. Background Art

[0002] As the requirements for audio and video transmission become higher and higher, the rack-mounted media network management platform needs to integrate more and more functional modules, so more and more business cards need to be installed in the existing rack-mounted media network management platform. At present, the rack-mounted media network management platform represented by 2U servers can support 10 codec modules, each of which can be freely combined, and the corresponding business cards can be hot-swapped. The server has a certain centralized management capability. However, the existing 2U servers still have the following shortcomings:

[0003] 1. As the existing 2U servers can only support up to 10 business cards, the product integration is not high enough to meet the growing functional requirements of audio and video transmission.

[0004] 2. The existing 2U server is not equipped with a centralized management software platform, or it only has a simple centralized management capability, which is just to centralize all the cards together and provide a unified power supply, but it cannot uniformly manage, maintain, and perform one-click firmware upgrades on all business cards.

[0005] 3. Existing 2U servers rely heavily on external third-party network switches to solve the network communication problems of business card boards. Therefore, an additional network switch needs to be configured, and a large number of network cables need to be connected between the 2U server and the network switch. For example, if 10 business card boards are set up in the 2U server, 10 network cables need to be connected between the 2U server and the network switch. The large number of network cables is not only difficult to manage, but also easy to cause accidental touching and pulling.

[0006] 4. In the existing 2U servers, the service card board plug-in structure is designed on the back of the product. This design method has the problem of difficulty in installing and replacing the service card board. When the 2U server is arranged in a small machine room or a broadcast vehicle with extremely small space, if the user wants to replace the service card board from the back of the 2U server, it is likely that the card board cannot be pulled out due to insufficient space. All signal lines, power lines, network cables, optical fibers, etc. of the entire 2U server must be disconnected, and the 2U server must be removed from the server cabinet to complete the replacement of the card board. The operation is extremely cumbersome and inefficient.

[0007] 5. The existing 2U servers are not equipped with display screens. If you want to check the running status and configuration of the server, you can only connect each business card to the computer and log in separately, and then check and modify the configuration in the background, which is very troublesome. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a rack-mounted media network management platform with a compact structure, easy disassembly and assembly, and network centralized management and network switching functions in order to address the problems of the low number of integrated business card boards in the existing rack-mounted media network management platform, the lack of centralized management capabilities, and reliance on external network switching.

A connecting rod assembly 8 is slidably provided on the inner wall of the chassis shell 1, and the connecting rod assembly 8 is connected to the front panel 2. Knobs 7 are provided between the two sides of the front panel 2 and the chassis shell 1 for connection. After loosening the knob 7, the front panel 2 is pulled, and with the assistance of the connecting rod assembly 8, the front panel 2 and the chassis shell 1 can be detachably connected, so that the service card board 9 can be disassembled and assembled from the front of the chassis shell 1. When the device is installed in a small space, even if there is no space to insert and remove the card board at the rear end of the chassis shell 1, it is only necessary to disconnect the signal line of the interface of the service card board 9, and it can be inserted and replaced from the front of the chassis shell 1 without disassembling the entire device, which is more flexible.

[0044] In this embodiment, the gold fingers of the business card board 9 and the main control card board 10 are connected to the PCB board 20. In this way, all card boards are powered through the gold fingers, and a network interconnection is formed between the business card board 9 and the main control card board 10 / network switch card board 11. The main control card board 10 can manage all business card boards 9, and all business card boards 9 can exchange network data with the network switch card board 11.

[0045] like Figure 4 As shown, in this embodiment, the rack-mounted media network management platform includes a main control card board 10, a network switch card board 11, and allows the insertion of up to 18 service boards 9 for audio and video encoding, decoding, integrated encoding and decoding, NDI, media gateway, etc. of different services, greatly improving the integration. By configuring service boards 9 with different functional modules, the rack-mounted media network management platform can be arbitrarily combined into various forms of products such as high-density multi-channel encoders, multi-channel decoders, multi-channel encoding / decoding integrated machines, multi-channel media gateways, and multi-channel aggregation decoding gateways, and the service forms can be arbitrarily combined and flexibly expanded.

[0046] like Fig.10As shown, in this embodiment, the service card board 9 is provided with three service interfaces 91 and a service gold finger 92, and the service gold finger 92 is connected to the service mother socket 16 to realize power supply and network connection with the main control card board 10 and the switch card board 11. The service card board 9 can adopt the RFN-60 4Kp60 HDMI encoding / decoding / NDI integrated service card: an integrated service card with encoding and decoding capabilities, supporting H.264 / H.265 / NDI SpeedHQ CODEC, and supporting 4Kp60 ultra-high-definition YCbCr 4∶2∶2 / 10bit color format. The service card board 9 can also adopt the RFN-6 high-definition HDMI encoding / decoding / NDI integrated service card: an integrated service card with high-definition encoding and decoding, supporting H.264 / H.265 / NDI SpeedHQ. Business card board 9 can also use RFN-50 4Kp60 12G-SDI encoding / decoding / NDI integrated business card: an integrated business card with encoding and decoding capabilities, supporting H.264 / H.265 / NDI SpeedHQ CODEC, and supporting 4Kp60 ultra-high-definition YCbCr 4∶2∶2 / 10bit color format. Business card board 9 can also use RFN-5 high-definition HDMI encoding / decoding / NDI integrated business card: an integrated business card with high-definition encoding and decoding capabilities, supporting H.264 / H.265 / NDI SpeedHQ.

[0047] like Fig.11 As shown, both ends of the main control card board 10 are provided with main control gold fingers 102, and the main control gold fingers 102 at one end are connected to the main control mother socket 21 to realize power supply and connection with all business card boards 9, and the main control gold fingers 102 at the other end and the USB interface 101 at the end of the main control card board 10 can connect external devices. In this embodiment, the main control card board 10 has a built-in high-performance ARM64 main controller and runs the KiloLink Server centralized management platform software, which can centrally manage and control all business card boards 9, and realize automatic discovery, automatic supervision, centralized status monitoring, fault diagnosis, parameter configuration, online distribution of firmware upgrades and other functions; at the same time, the main control card board 10 also supports more advanced business functions of KiloLink Server, such as media aggregation services for Kiloview's 4G / 5G wireless aggregation products, supporting KiloLink aggregation services, allowing Kiloview wireless aggregation products to be directly aggregated and connected through 4G / 5G; by extending the decoding business card 9, 4G / 5G aggregation can be realized to directly output baseband video.

[0048] In this embodiment, the working principle of the KiloLink Server centralized management platform software includes: Web access management based on HTTP / HTTPS; real-time display of device working status information (network / CPU / memory / temperature / performance); real-time display of basic information and working status of each card board module; management and configuration of the device, such as modifying the device name / network IP address, setting encoding / decoding / conversion parameters, creating streaming media services, upgrading firmware, etc.; supporting Microsoft Edge / Firefox / Chrome / Safari / Opera web browsers; providing HTTP / HTTPS API for users to perform remote (programmable) calls / controls; allowing software upgrades by uploading firmware through the Web management interface.

[0049] In this embodiment, the network switch card 11 has a built-in 240Gbps 10G network layer 3 managed switch module, and all service cards 9 in the device are connected to the 1G / 2.5G network switch module on the network switch card 11 through the card gold finger socket. Fig.12 As shown, the network switch card board 11 is provided with a switch gold finger 111, a 10G network port 112 and three 10G optical fiber ports 113. The rack-mounted media network management platform ultimately provides three 10Gbps SFP+ optical fiber Ethernet interfaces and one 10Gbps RJ45 Ethernet interface to connect to the external network.

[0050] The rack-mounted media network management platform has built-in network switching, so there is no need to purchase an additional network switch device, nor is there a need to provide an additional power socket and power cord for the network switch, saving costs; there are no complicated network cables, saving installation space. 18 business card boards 9 mean that 18 network cables are required to connect to the external switch, which will occupy a larger installation space; the internal PCB board of the management platform has shorter wiring, the network signal transmission quality is better, and it also avoids unforeseen problems caused by loose / pulling damage of external cable plugs, thereby improving the stability of network transmission.

[0051] like Figure 5 As shown, in this embodiment, a dual redundant hot backup power supply module 13 is also provided in the chassis housing 1. The power supply module 13 is connected to the PCB board 20 via a power jumper 19 to realize centralized power supply to the business card board 9 and the main control card board 10.

[0052] like Figure 7As shown, two copper bars 201 are soldered to the lower back of the PCB board 20 along the length direction of the PCB board 20, one for each positive / negative current pole, and the business mother socket 16 and the main control mother socket 21 are both connected to the copper bars 201. The copper bars 201 can not only realize excessive current, but also provide support for the PCB board 20 to prevent the PCB board 20 from deforming due to its large size. The power input port 202 is located on one side of the copper bar 201, and the power input port 201 is located at the lower right side of the UPCB board 20. The power input port 202 is connected to the power module 13 through the power jumper 19.

[0053] In this embodiment, the power module 13 is a 2×550W dual redundant hot backup power supply, which leads the current to the PCB board 20 through two pairs of high-current jumpers, and can centrally provide stable power supply of up to 28W or more to each business board 9, and supports hot plugging. Even if one of the power modules 13 suddenly stops working, there will be no power outage, and the user can replace it calmly.

[0054] In the rack-mounted media network management platform, a large number of service card boards 9 are often integrated. In this embodiment, the number of service card boards 9 is as many as 18. At the same time, a main control card board 10 and a network switch card board 11 are also provided in the rack-mounted media network management platform. The main control card board 10 is used to centrally manage these service card boards 9. The whole machine has as many as 20 card boards. Each service card board 9 needs to communicate and transmit data with the main control card board 10 in a two-way manner, and the power module 13 also needs to supply power to each service card board 9 through the PCB board 20. At the same time, each service card board 9 also needs to have an external interface (at least 3 interfaces). In order to expose these interfaces, the PCB board 20 forms a U-shaped structure, and the wiring area left for communication and power supply becomes extremely narrow.

[0055] In this embodiment, the PCB board 20 can not only supply power to all the cards, but also be the network connecting the entire system. The left side of the U-shaped PCB board 20 is connected to the power module 13, and the right side is provided with the main control card board 10. Figure 8 As shown, the power supply starts from the V+ / V- on the left side and gradually decreases from left to right, supplying power to 18 business card boards 9 and 1 main control card board 10 respectively; Fig. 9 As shown, the network signal lines of the 18 service card boards 9 and the main control card board 10 gradually increase from left to right and converge to the rightmost main control socket 21, and are connected to the main control card board 10. Through the above distributed layout with the power supply on the left and the main control card board 10 on the right, the power supply wiring and the network wiring are staggered, the wiring area of ​​the U-shaped PCB board 20 is used as much as possible, the number of layers of the PCB Layout is reduced, thereby reducing the manufacturing cost, and also helping to reduce the overall volume of the rack-mounted media network management platform.

[0056] like Figure 5As shown, the bottom plate 17 of the chassis housing 1 is provided with a plurality of parallel guide grooves 18, and the guide grooves 18 are used to assist in installing the service card board 9 and the main control card board 10, so as to improve the convenience of disassembly and assembly of the cards.

[0057] Due to the high density integration of the service card board 9, the heat generated during the operation process will also be very large. Figure 3 As shown, a cooling fan 12 is also provided in the chassis shell 1, and the cooling fan 12 is respectively arranged on the inner side of the front panel 2 and the rear of the power module 13, so as to dissipate heat for the service card board 9 and the power module 13. Accordingly, a plurality of ventilation holes 6 are provided on the front panel 2. The large-area ventilation holes 6 can provide a large air intake volume for heat dissipation of the entire system. Relying on the unobstructed air duct of the middle card board part and the heat dissipation holes on the back / top surface of the chassis shell 1, the entire system achieves a strong heat dissipation effect.

[0058] like Figure 1 As shown, a display screen 3 is provided on the front panel 2, and a plurality of buttons 5 are provided below the display screen 3, so that the user can quickly monitor the status and adjust the configuration, and can also perform some basic configurations.

[0059] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
