The outlet duct and the inlet duct 315 are respectively fixed on the inner wall of the optical cable well 31. The lowest end of the outlet duct is much lower than the lowest end of the inlet duct 315, so as to ensure as much as possible that the air in the inlet duct 315 can be circulated inside the optical cable well 31 and then discharged by the outlet duct.

[0041] An exhaust fan is provided at the bottom end of the air outlet duct to guide the wind inside the optical cable well 31 to be discharged out of the optical cable well 31 .

[0042] As shown in Figure 8, in this embodiment, the air outlet duct and the air inlet duct 315 are respectively provided with arc-shaped openings near the top, and the extension length of the arc-shaped opening is half of the outer circumference length of the air outlet duct or the air inlet duct 315. A placement box 3151 is provided at the arc-shaped opening, and a fixing block is fixed on the inner side wall of the air outlet duct and the air inlet duct 315 opposite to the arc-shaped opening. A fixing groove is provided on the placement box 3151, which can be fixed with the fixing block, and is used to fix the placement box on the air outlet duct or the air inlet duct 315.

[0043] In this embodiment, a handle is provided on the side of the placement box opposite to the arc-shaped opening, so that the staff can pull it out to replace the filter element or filter net in the placement box.

A fixing plate 314 is provided on the top of each of the two square grooves. A switch assembly 312 is provided between the fixing plate 314 and the square grooves.

[0046] An air outlet is opened at the bottom of one square groove, and the air outlet is connected to the air outlet duct through a bellows. An air inlet is opened at the bottom of another square groove, and the air inlet is connected to the air inlet duct 315 through a bellows. The bellows can reduce the impact of the manhole cover 311 on the air outlet duct and the air inlet duct 315 when it is opened.

[0047] The switch assembly 312 includes multiple springs 3121, multiple electromagnets 3122 and multiple magnet blocks 3123. The multiple springs 3121 are respectively arranged around the extension part 313.

Rectangular grooves are respectively provided in the middle around the extension part 313, and the multiple electromagnets 3122 are fixed in the rectangular grooves.

[0048] When the two fixing plates 314 need to be opened to ventilate the optical cable well 31, the multiple electromagnets 3122 are powered off, and the magnet block 3123 set on the fixing plate 314 is not adsorbed on the electromagnet 3122. Under the action of the spring 3121, the fixing plate 314 pops out of the square groove, and there is a certain height difference between the fixing plate 314 and the square groove, so that air is discharged and sucked. Figure 6 When closing is required, it is only necessary to energize the multiple electromagnets 3122, and the magnet block 3123 set on the fixed plate 314 is adsorbed on the electromagnet 3122, thereby achieving the closure of the fixed plate 314 and the square groove.

[0049] In this embodiment, a sealing ring is provided on the fixing plate 314 to ensure the sealing of the entire optical cable well 31 when the fixing plate 314 and the square groove are closed.

[0052] The optical cables 21 are connected via an optical fiber splicing box 32 .

[0053] Wall holes 33 are opened on both sides of the airport runway 5 in the same direction as the extension of the airport runway 5 , and the optical cables 21 at different positions can be guided through the wall holes 33 to form a complete link between sending and receiving.

[0055] The signal transmission system 1 includes an optical transmitter 11 for generating an optical signal to be transmitted in an optical cable 21 .

[0056] The optical transmitter 11 is installed in the control center of the airport to generate and output optical signals; the optical signals are transmitted to the runway layout area through the optical cable 2121 and form a continuous monitoring network in the grid under the runway.

[0057] The optical transmitter 11 can adjust the signal strength and frequency in real time to ensure that the signal meets the requirements of long-distance transmission while reducing power consumption. In addition, the signal transmission system 1 can be linked with the signal receiving and monitoring system 4 to support remote control and real-time signal detection, significantly improving the flexibility and efficiency of the system.

[0058] To prevent the attenuation of optical signals during long-distance transmission, optical repeaters 22 are evenly distributed in the optical cable 21 to enhance the strength of the optical signal and ensure stable signal transmission quality and comprehensive coverage throughout the runway.

[0059] In this embodiment, the optical signal generated by the optical transmitter 11 is sorted and distributed through the optical fiber distribution frame 41, and the optical signal is sent to different optical cables 21.

The fiber distribution frame 41 is used to organize, distribute and manage the optical cables and transmit the optical signal to the optical receiver 42. The optical receiver 42 is connected to the terminal control device 43 . The optical receiver 42 converts the optical signal into an electrical signal, amplifies, filters and analyzes the signal, and transmits the signal to the terminal control device 43 .

[0061] The terminal control device 43 is connected to the optical transmitter 11 and the optical receiver 42 respectively, and is used to control the intensity and frequency of the optical signal generated by the optical transmitter 11, and detect the broken position of the optical cable 21 in real time through the electrical signal generated by the optical receiver 42, so as to realize the positioning and identification of the unexploded bomb.

[0062] The terminal control device 43 monitors the signal status of the runway optical cable 21 in real time through a built-in software interface, and can determine the location of the unexploded bomb by detecting the break of the optical cable 21. The control device supports remote operation and can quickly command maintenance personnel to repair the optical cable 21 or take other emergency response measures.

Multiple intersections are formed according to the multiple interlaced optical cables 21 of each layer, the damaged position of the optical cable 21 is monitored, and the horizontal position of the unexploded bomb is located by combining the intersection with the mark; S3. The depth of the unexploded bomb is determined by the spacing of each layer of optical cables 21 in combination with the markings, thereby achieving accurate positioning of the unexploded bomb.

[0064] In this embodiment, the optical cables 21 of the airport runway 5 are laid out in a plane-crossed grid structure, and are laid out in zones along the length and width of the runway. The laying points of the optical cables 21 are arranged in a staggered manner at intervals to form a plurality of intersections, through which the horizontal plane position of the optical cables 21 can be accurately located.

[0065] The buried depth of the optical cables 21 is arranged in layers at intervals downward; through the grid structure of the cross-arranged optical cables 21, full coverage of the runway area can be achieved, ensuring that optical cables 21 are distributed in every area.

[0066] In actual operation, by monitoring the damaged position of the optical cable 21, the horizontal position of the unexploded bomb can be located through the intersection; combined with the information of the buried depth of the optical cable 21, the buried depth of the unexploded bomb can also be accurately determined; it can provide higher accuracy and effectively improve the positioning capability of the unexploded bomb. Thus, the coverage range is maximized and the accuracy of signal detection is achieved; further, the starting end and the connection point of the optical cable 21 are combined with the divided area and the layer to set a unique number mark to ensure that the broken position of the optical cable 21 can be quickly identified, so as to achieve the purpose of accurately locating the unexploded bomb.

[0067] The layout diagram and front view of the airport runway 5 optical cable 21 of this embodiment are as follows Figure 2 and Figure 3 As shown, the optical cables 21 are arranged in zones and layers along the length direction of the runway below the runway. Each layer is arranged in a grid pattern to form a number of intersections, and unexploded bombs can be located by damaging the optical cables 21 .
