Detailed implementation manners

[0044] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0045] Please refer to Figures 1-6 , and now a two-way portable networkable optical transmission device disclosed by the present utility model will be described. The present utility model is composed of seven parts, as Figure 1 , including a display component 1, an exhaust component 2, a control component 3, a power interface 4, a power supply component 5, a wiring component 6 and an installation housing 7. The interior of the installation housing 7 is a hollow structure, and the power supply component 5 is installed in the hollow structure. The control component 3 is installed in the hollow structure. The wiring component 6 is installed on the front surface of the installation housing 7. A power interface 4 is provided on the right side of the wiring component 6. One end of the power interface 4 extends into the hollow structure. The display component 1 is installed on the rear surface of the installation housing 7. An exhaust component 2 is provided on the right side of the display component 1. One end of the exhaust component 2 is arranged in the hollow structure.

[0046] When the utility model is in use, two optical transmission devices are connected by an optical fiber cable. Then, one end of a power cord is connected to the power interface 4, and the other end is connected to a power supply. The power supply can use an AC power supply. After the power supply is connected, one transmission line is connected to the SDI output interface 65 of one optical transmission device, and another transmission line is connected to the SDI input interface 64 of the other optical transmission device. Then, the other ends of the two transmission lines are respectively connected to a video receiving device and a camera. When the camera receives a video signal, the video signal is transmitted through the transmission line. At this time, the connection bracket 61 is connected to the medium-wave optical splitter 33 through a wire. The CWDM technology is adopted in the medium-wave optical splitter 33 to convert the video signal entering the medium-wave optical splitter 33 into an optical signal. The optical signal will be decomposed into optical signals of different wavelengths by the medium-wave optical splitter 33, and then the optical signals of different wavelengths are combined into one optical fiber by using the CWDM technology, so that one optical fiber can carry both upstream and downstream data at the same time. Then, the optical signal is transmitted to another optical transmission device by using the optical fiber cable. The optical signal is converted into a video signal again by using the medium-wave optical splitter 33. Then, the video signal enters the transmission line through the SDI output interface 65. Finally, the video signal is fed back to the user through the video receiving device. The display component 1 displays the working state of each signal and its current signal strength value, providing a reference for safe broadcasting. The exhaust component 2 cools the interior to ensure the normal operation of each component. Through the optical fiber cable, the typical transmission distance can be achieved to be not less than 10 kilometers, and there is also an 80-kilometer long-distance module available.

[0047] In a specific embodiment, the control component 3, the power supply component 5, the wiring component 6, the power interface 4, the display component 1 and the exhaust component 2 are connected by wires, and the wires are arranged inside the installation shell 7.

[0048] In a specific embodiment, such as Figure 2, the wiring component 6 includes a connection bracket 61, a through hole 62, a connection plate 63, an SDI input interface 64, an SDI output interface 65, and an optical fiber coupler 66. A number of connection brackets 61 are installed above the bottom surface of the installation housing 7, and a number of connection plates 63 are installed above the bottom surface of the installation housing 7. Two connection plates 63 are placed on the left and right sides of a connection bracket 61. The upper end of the connection bracket 61 is connected to the connection plate 63 through the through hole 62. The SDI input interface 64 is installed at the front end of the connection plate 63, and the front end of the SDI input interface 64 passes through the front surface of the installation housing 7. The SDI output interface 65 is installed at the front end of the connection plate 63, and the front end of the SDI input interface 64 passes through the front surface of the installation housing 7. The SDI output interface 65 is arranged below the SDI input interface 64. The optical fiber coupler 66 is installed on the front plate of the installation housing 7. The optical fiber coupler 66 is arranged on the right side of the SDI input interface 64, and one end of the optical fiber coupler 66 is arranged inside the installation housing 7. The optical fiber coupler 66 is used to connect the optical fiber cable. The SDI input interface 64 and the SDI output interface 65 can be set as a unidirectional six-way interface or a bidirectional twelve-way interface on an optical transmission device. The unidirectional six-way interface means that only six SDI input interfaces 64 or SDI output interfaces 65 are set on the optical transmission device, while the bidirectional twelve means that six SDI input interfaces 64 and six SDI output interfaces 65 are set on an optical transmission device at the same time. The setting of the through hole 62 is to connect the connection bracket 61 and the connection plate 63 to ensure the conduction of the circuit, and such a setting also facilitates the replacement of the connection plate 63.

[0049] In a specific embodiment, such as Figure 3 , the power supply component 5 includes a main power supply board 51 and an SDI power supply board 52. The SDI power supply board 52 is installed at the upper end of the bottom plate of the installation housing 7. The SDI power supply board 52 is connected to the wiring component 6 through a wire. The main power supply board 51 is installed at the upper end of the bottom plate of the installation housing 7. The main power supply board 51 is arranged on the right side of the SDI power supply board 52. Part of the control component 3 is installed above the main power supply board 51. The setting of the SDI power supply board 52 is to divert the current in the main power supply board 51 so that the current enters the video receiving device and the camera through the transmission line to supply power to the video receiving device and the camera, while the setting of the main power supply board 51 is used to supply power to each electrical appliance. Through the setting of the two power supply boards, the incoming current is processed to prevent the electrical appliance from being burned out due to excessive current or voltage. The power interface 4 can be connected to alternating current and direct current, making the application scenario of the device wider.

[0050] In a specific embodiment, such as Figure 4, the control component 3 includes a power supply 31, a boost converter 32, and a medium-wave optical splitter 33. The power supply 31 is installed at the upper end of the main power supply board 51. The boost converter 32 is also installed at the upper end of the main power supply board 51 and is arranged behind the power supply 31. The medium-wave optical splitter 33 is installed at the upper end of the bottom plate of the installation housing 7 and is arranged behind the SDI power supply board 52. The medium-wave optical splitter 33 is an optical splitter for processing light waves in the medium-wave range. Such an optical splitter has specific dispersion elements or optical thin-film structures to optimize the separation and detection of light waves in the medium-wave range. In this way, the optical signal is decomposed into light waves of different wavelengths, and this method is the CWDM technology. The power supply 31 converts standard alternating current into low-voltage and stable direct current, and the boost converter 32 is to increase the input DC voltage to the required output voltage level through conversion to ensure the stable operation of each electrical appliance.

[0051] In a specific embodiment, such as Figure 5 , the display component 1 includes a lamp board adapter 11 and an LED display screen 12. The lamp board adapter 11 is installed on the front surface of the rear board of the installation housing 7, and the LED display screen 12 is embedded in the rear board of the installation housing 7. The LED display screen 12 is connected to the lamp board adapter 11 through a wire. The lamp board adapter 11 can effectively connect the lamps to the power supply or other control devices and is used to supply power to the LED display screen 12 here.

[0052] In a specific embodiment, such as Figure 6 , the exhaust component 2 includes a connection block 21 and an exhaust port 22. The exhaust port 22 is opened on the rear board of the installation housing 7 and is arranged on the right side of the display component 1. The connection block 21 is installed on the front surface of the rear board of the installation housing 7, and a fan is installed in the connection block 21. The outside cool air is introduced into the interior of the installation housing 7 through the connected fan to cool the electrical appliances, and the exhaust port 22 is provided for the circulation of air.

[0053] In a specific embodiment, such as Figures 7-9, through point-to-point connections, each node can be directly connected to other nodes without relying on a central server. Therefore, when a certain node fails, it will not affect the entire signal transmission, enhancing the network's fault tolerance and reliability. Since data is directly transmitted between nodes, the forwarding and processing time of intermediate devices is reduced, thereby reducing the latency of data transmission and improving the real-time performance and response ability of the network. In a single-point-to-two-point or point-to-multipoint networking, a central node is allowed to communicate with multiple nodes simultaneously, improving the efficiency of data transmission and reducing the number of communication lines and devices, thus saving resources. In a multi-point ring connection, each node is connected to other nodes through links to form a closed loop. When a certain node or link fails, data can continue to be transmitted through other paths, ensuring the reliability of the network. By using point-to-point communication links, the transmitted signal is regenerated at each node, so the bit error rate of the transmitted information can be greatly reduced.

[0054] Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
