Description

Technical Field

[0001] This utility model belongs to the field of railway communication poles, and in particular relates to an optical communication pole for providing emergency communication support in special sections of railways. Background Technology

[0002] Special railway sections include those along the railway tracks and in tunnels. These sections are enclosed and relatively fixed environments, facing risks from extreme natural disasters such as earthquakes, fires, and floods, as well as operational risks such as vehicle loss of control, pipeline leaks, and power outages. In the event of an emergency in a special railway section, the ability to quickly evacuate personnel, coordinate repair tasks, and effectively mobilize emergency rescue resources is crucial to ensuring railway transportation safety.

[0003] Traditional intercom posts use an analog system, where only one voice signal can be transmitted per pair of copper core cables. For emergency communication alone, several pairs of copper core cables are needed to achieve simple multi-channel voice communication. With the rapid iteration of railway communication technology, traditional intercom posts can no longer meet the needs of modern railway section emergency and protection work, mainly due to limitations in communication functions, inconvenience in use and maintenance, and inherent defects in the equipment.

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 5 As shown, an optical communication column for providing emergency communication support in special sections of railways is based on a GPON system. The GPON system includes an optical line terminal (OLT), an optical distribution network (ODN), and multiple optical network units (ONUs). The optical communication column includes a column body 1, a door panel 22, a partition plate 8, an optical cable splice box 2, a winding wheel, a splitter 14, and a splitter rotating frame. A door panel 22 is provided at the front of the column 1. An optical cable splice box 2 is provided on one side of the interior of the column 1, and a partition plate 8 is provided on the other side. The partition plate 8 is parallel to the door panel 22 and divides the interior of the column 1 into a front accommodating space 25 and a rear accommodating space 26. A first mounting port 4 and a second mounting port 10 are provided on the partition plate 8. A stepped mounting frame is provided in the first mounting port 4. The stepped mounting frame includes an expansion interface panel 5, an optical network unit mounting plate 7, and a step plate 23. The expansion interface panel 5 is connected to the optical network unit mounting plate 7 through the step plate 23. The expansion interface panel 5 and the optical network unit mounting plate 7 are parallel to each other, and the expansion interface panel 5 is located in front of the optical network unit mounting plate 7. An optical network unit 9 is installed on the optical network unit mounting plate 7. The optical network unit mounting plate 7 and the optical network unit 9 are located in the rear accommodating space 26. The winding wheel and the beam splitter rotating frame are disposed in the rear receiving space 26. The winding wheel includes an upper winding post 11 and a lower winding post 12 spaced apart from each other. The beam splitter rotating frame includes a rotating plate 13, a limiting post 17, a storage groove 15, a rotating shaft 16, and a rotating shaft seat 21. The rotating shaft 16 is located below the winding wheel and is mounted on the rotating shaft seat 21. The bottom edge of the rotating plate 13 is connected to the rotating shaft 16, and the rotating plate 13 reciprocates around the rotating shaft 16. The limiting post 17 is disposed between the upper winding post 11 and the lower winding post 12. The upper surface of the rotating plate 13 abuts against the limiting post 17. The lower surface of the rotating plate 13 is provided with a storage groove 15, and the beam splitter 14 is fitted into the storage groove 15. The hollow area of ​​the second mounting port 10 is correspondingly disposed with respect to the winding wheel and the beam splitter rotating frame.

[0021] The GPON (Gigabit-Capable Passive Optical Network), also known as a passive optical network, consists of an optical line terminal (OLT) at the central office, an optical distribution network (ODN), and optical network units (ONUs) on the user side. The GPON system is a single-fiber bidirectional optical access network employing a point-to-multipoint (P2MP) architecture. In the downlink direction (OLT to ONU), signals transmitted by the OLT reach each ONU through the ODN. In the uplink direction (ONU to OLT), signals transmitted by the ONU only reach the OLT and not other ONUs. To avoid data collisions and improve network efficiency, the uplink direction uses TDMA (Telematics Multiple Access) and manages the data transmission of each ONU. The ODN provides an optical path between the OLT and the ONUs.

[0022] An optical communication tower for providing emergency communication support in special railway sections is disclosed. This tower utilizes fiber optic communication and offers advantages such as low loss, resistance to electromagnetic interference, light weight, and high security. The system employs fiber optics for full-channel networking, resulting in strong anti-interference capabilities, low loss, high call quality, and low latency. A splitter is used to achieve both node service and line continuity functions, increasing the overall line length and the number of nodes. The optical communication tower features a rational layout through partitions, stepped mounting frames, and a splitter rotating frame, minimizing space occupation. This invention provides a convenient and safe optical communication tower for railway sections, enabling emergency communication transmission of voice, data, and images.

[0023] like Figure 8As shown, the Optical Line Terminal (OLT) is located in a special section of the railway. Multiple optical intercom posts 1, 2, etc., are spaced apart along this section. The input of the splitter 14 of optical intercom post 1 is connected to the OLT at the central office via an optical cable splice box 2. The output of the splitter 14 is connected to the Optical Network Unit (ONU) 9 and the optical cable splice box 2 of another adjacent optical intercom post. Similarly, the input of the splitter 14 of optical intercom post 2 is connected to the splitter 14 of optical intercom post 1 via an optical cable splice box 2. The output of the splitter 14 of optical intercom post 2 is connected to the ONU 9 and the optical cable splice box 2 of another adjacent optical intercom post, and so on to other optical intercom posts. By directly leading the optical cable to the intercom posts, the service carrying capacity of the intercom posts is improved, making communication more efficient and flexible. The GPON system also has higher transmission bandwidth, capable of adapting to the needs of multi-channel high-definition video transmission. The splitter is a passive device; when this node has no external power supply, it does not affect the network connectivity of the next node.

[0024] like Figure 1 As shown, the expansion interface panel 5 is provided with an optical fiber expansion port and a power interface, which are connected to the optical network unit 9. The optical network unit 9 is provided with a telephone interface and an Ethernet interface. More preferably, it also includes an emergency terminal box, which contains a power bank, a router, and a telephone. The power bank is used to supply power to the optical network unit 9 through the power interface of the expansion interface panel 5, the router is used to connect to the network through the optical fiber expansion port of the expansion interface panel 5, and the telephone is used to connect to the telephone interface of the optical network unit 9.

[0025] like Figure 2 and Figure 3 As shown, when the rotating plate 13 rotates into the cylinder, its upper edge presses against the limiting post 17, and the upper winding post 11 is located above the rotating plate 13; when the rotating plate 13 rotates outward, its upper edge rotates out from the second mounting port 10 to the front accommodating space 25. The height of the limiting post 17 is higher than the height of the winding wheel. Figure 5 As shown, the upper winding post 11 and the lower winding post 12 have semi-circular cross-sections and are mirror images of each other. The rotating plate 13 can open outwards or retract inwards, rationally planning space and providing cable storage for easy and quick cable identification. Furthermore, when the rotating plate 13 is opened outwards, it forms a temporary workbench that can be used to place power banks, routers, and telephones for convenient on-site operation.

[0026] like Figure 2As shown, an integrated base 20 is also provided within the rear accommodating space 26. The winding wheel, limiting post 17, and beam splitter rotating frame are mounted on the integrated base 20, which is installed on the back plate of the column 1 with screws. This facilitates overall disassembly or installation and improves maintenance efficiency.

[0027] The optical communication column is designed in two structures: freestanding and wall-mounted. Figure 7 As shown, it also includes a base for the optical communication column. The optical communication column is mounted on the base, which includes a base plate 30, a square base column 32, a protective base 33, and reinforcing ribs 31. The base column 32 is mounted on the base plate 30, and multiple reinforcing ribs 31 are provided between the base column 32 and the base plate 30. The protective base 33 is mounted on the base column 32, and the protective base 33 has an installation opening 34. The bottom of the column 1 is fitted into the installation opening 34. The optical communication column base constitutes a column-type optical communication column, which can be installed beside the outer track of the tunnel.

[0028] like Figure 6 As shown, it also includes a mounting backplate 27, which is connected to the back of the column. The mounting backplate 27 forms a wall-mounted optical communication column, suitable for installation on the inner wall of a tunnel.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
