[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0029] The embodiment of the present application provides a data forwarding device, which can avoid the problem of incompatibility between the interface and communication protocol of the monitoring device and the border monitoring system. The composition structure of the device is as follows: Figure 1 As shown, the system includes an input module, a first processing module, a second processing module, and an output module. The input module includes a first input interface and a first output interface, and the output module includes a second input interface and a second output interface. The first input interface is connected to the output of different monitoring devices, and the second output interface is connected to the input of the border monitoring system. The first processing module is connected to the first output interface of the input module and the second processing module; the second processing module is connected to the second input interface of the output module.

[0030] The input module and output module are modules that forward data, such as switches. The input module's input interfaces include standard USB 2.0, SATA, RJ45, HDMI, BNC, and other commonly used interfaces. The first processing module decodes the communication data to obtain video data. The first processing module supports common communication protocols such as RTSP, Onvif, and GB / T-28181. Furthermore, the first processing module can identify and process the video data, sending the processed video data to the second processing module.

[0031] Based on the above structure, the device is configured as follows: the monitoring device can perform communication decoding on the captured video data to obtain communication data, and then send the communication data to the input module. The input module receives the communication data sent by the monitoring device through the first input interface and sends the communication data to the second processing module through the first output interface. The first processing module receives the communication data sent through the first output interface, performs communication decoding on the communication data to obtain video data, and then sends the video data to the second processing module. The second processing module receives the video data sent by the first processing module, performs communication decoding on the video data using the target communication protocol used by the border monitoring system, obtains target communication data compatible with the target communication protocol, and then sends the target communication data to the second input interface. The output module receives the data from the second input interface and sends the target communication data to the border monitoring system through the second output interface.

[0032] Since different monitoring devices are produced by different manufacturers, and different vendors use different interfaces and communication protocols, monitoring devices produced by different manufacturers may be incompatible with the interfaces and communication protocols of the border monitoring system. In order to solve this problem, the present application provides a data forwarding device that can be connected to different monitoring devices and convert the communication protocol used for the data transmitted by the monitoring device into a communication protocol compatible with the border monitoring system, and then send the converted data to the border monitoring system. Therefore, through the data forwarding device provided by the present application, the data of the monitoring device is converted into a protocol, thereby avoiding the problem of incompatible communication protocols. At the same time, the data forwarding device of the present application, as a data transfer device, also avoids the direct connection between the monitoring device and the border monitoring system, avoiding the problem of interface incompatibility.

[0033] Optionally, the input module is a first switch, the first input interface is a preset interface of the first switch, and the first output interface is an interface other than the preset interface of the first switch.

[0034] To expand more interfaces, this embodiment can perform interface expansion based on a switch. A preset interface of a first switch is designated as the first input interface, and other interfaces in the first switch are designated as first input interfaces. For example, the input module uses a 10-port Gigabit switch, and the first interface in the switch is designated as the first output interface, while the other interfaces are designated as first input interfaces.

[0035] Optionally, when the input module includes multiple first switches, the device further includes a second switch, the input interface of the second switch is connected to the output interface of each first switch, and the output interface of the second switch is connected to the first processing module.

[0036] In practice, since a switch has limited interfaces, multiple first switches can be installed in the input module to expand the number of interfaces. When the input module includes multiple first switches, since each first switch has at least one output interface, the multiple switches have multiple output interfaces. To connect the output interfaces to the first processing module, a second switch can be installed between the input module and the first processing module. This allows the output interfaces of the multiple first switches to connect to the input interfaces of the second switch, and the output interfaces of the second switch to connect to the first processing module.

[0037] For example, the input module uses two 10-port Gigabit switches, with the first port on each switch used as the first output port and the remaining ports used as the first input port. Meanwhile, the second switch uses a 16-port Gigabit switch, with the first and second ports used as input ports and the ninth and tenth ports used as output ports. In this case, the first port on each of the two 10-port Gigabit switches can be connected to the ninth and tenth ports, respectively.

[0038] Optionally, in addition to the first switch, the input module in the embodiment of the present application may also include a submodule with other types of interfaces, such as an RS485 submodule, a standard definition encoding submodule, and a high definition encoding submodule.

[0039] The RS485 submodule has an RS485 input interface and an output interface compatible with the second switch interface. The SD encoding submodule has an SD video input interface and an output interface compatible with the second switch interface. The HD encoding submodule has an HD video input interface and an output interface compatible with the second switch interface.

[0040] Optionally, the output module further includes a third switch, the second output interface is a first preset interface in the third switch, and the second input interface is a second preset interface of the first switch.

[0041] Optionally, when the second processing module includes multiple ones, the device further includes a fourth switch, the input interface of the fourth switch is connected to the first processing module, and the output interface of the fourth switch is connected to the second processing module.

[0042] In this embodiment, a fourth switch may be further provided between the first processing module and the second processing module to send data output by the first processing module to multiple second processing modules, so as to output the data through multiple interfaces.

[0043] Optionally, the output module also includes an HDMI decoding submodule, the input interface of the HDMI decoding submodule is connected to the second processing module, the output interface of the HDMI decoding submodule is connected to the input interface of the third switch, and the output interface of the third switch is connected to the input end of the border monitoring system.

[0044] Before implementation, to confirm the proper functioning of the data forwarding device, technicians must first verify the accuracy of the data converted by the data conversion device. If the converted data is correct, the data forwarding device can be confirmed to be functioning properly. To verify the accuracy of the converted data, the technicians must display it on a display. Therefore, an HDMI decoding submodule with an HDMI interface compatible with the display interface is required. During implementation, the HDMI decoding submodule can be connected to a third switch to transmit the data to the border monitoring system.

[0045] The HDMI decoding submodule can also convert the video data into high-definition video data, and send the high-definition video data to the display through the HDMI interface of the HDMI decoding submodule.

[0046] For example, when video data needs to be sent to a display, the HDMI interface of the HDMI decoding submodule needs to be connected to the input terminal of the display. When video data does not need to be sent to the display, the HDMI interface of the HDMI decoding submodule needs to be connected to the interface of the switch.

[0047] It should be noted that, when multiple second processing modules are provided, an HDMI decoding submodule may be provided for each second processing module. Specifically, the second processing module is connected to the input interface of the HDMI decoding submodule.

[0048] Optionally, the device further includes a power module, which is respectively connected to the input module, the first processing module, the second processing module and the output module.

[0049] In this embodiment, the power supply module can supply power to the input module, the first processing module, the second processing module, and the output module.

[0050] It should be noted that the power module can also provide power to other devices in the data forwarding device that require power. For example, the power module can provide power to the first switch, the second switch, the third switch, and the fourth switch.

[0051] Optionally, the device further includes a fan, wherein the fan is connected to the power module.

[0052] In this embodiment, in order to dissipate heat from the data forwarding device, a fan may be provided in the data forwarding device, and the fan is powered by the power module.

[0053] Optionally, the device further includes a heat sink, wherein the heat sink is connected to the power module.

[0054] In this embodiment, in order to dissipate heat from the data forwarding device, a heat sink may be provided in the data forwarding device, and the heat sink may be powered by the power module.

[0055] Optionally, the device further includes a storage module, which can be connected to the first processing module and the second processing module and is used to store data to be processed or stored in the processed data. The storage module can be a SATA hard disk box.

[0056] In addition, a SATA interface can also be set in the device to connect an external hard disk.

[0057] Optionally, the above components can also use hardware that meets military standards to ensure that they can still operate stably in extreme environments such as high temperature, low temperature, humidity, and dust. At the same time, the hardware redundancy design of the equipment is improved, the fault tolerance of the system is enhanced, and continuous operation is ensured under any circumstances. The mean time between failures (MTBF) of the information fusion processing equipment is 12100h; the operating temperature range of the equipment is -20℃ to 55℃, and the storage temperature range is -55℃ to +70℃. The information fusion processing equipment (F-8124TP) supplied by our company is a domestic brand, Zhongke Futong, which ensures the security of data collection and transmission in emergency situations.
