The rear ends of the two rotating shafts 3 28 are fixedly connected to the two bevel gears 27 respectively, and the front ends of the two rotating shafts 3 28 are fixedly connected to a rotating disk 29. Slide grooves are provided inside the two swinging rods 20, and sliders 30 are slidably provided inside the two slide grooves. Moving rods 31 are fixedly connected to the rear sides of the two sliders 30. Connecting rods 1 32 are fixedly connected to the front sides of the two rotating disks 29, and connecting rods 2 33 are fixedly connected to the front sides of the two moving rods 31. Pull rods 34 are sleeved on the outside of the two connecting rods 1 32, and the two pull rods 34 are sleeved on the two On the outside of the connecting rod 2 33, the pull rod 34 is connected to the connecting rod 1 32 and the connecting rod 2 33 through bearings. Two positioning rods 35 are fixedly connected to the inner wall of the rear side of the shell 18. The two positioning rods 35 respectively penetrate the two moving rods 31 and are slidably connected thereto. A bottom plate 36 is provided at the bottom of the shell 18. An L-shaped plate 37 is fixedly connected to the top of the bottom plate 36. A motor 2 38 is fixedly connected to the bottom of the bottom plate 36. A reciprocating screw 39 is fixedly connected to the output shaft of the motor 2 38. The reciprocating screw 39 penetrates the bottom plate 36 and is connected to the inner wall of the top of the L-shaped plate 37. A sliding seat 40 connected thereto through a ball screw pair is sleeved on the outside of the reciprocating screw 39. The sliding seat 40 is fixedly connected to the rear side of the shell 18. Two guide screws are fixedly connected to the bottom of the shell 18 The guide rod 41 and the two guide rods 41 both penetrate the bottom plate 36 and are slidably connected thereto. The motor 1 24 drives the rotating shaft 25 to rotate. The rotating shaft 25 drives the two bevel gears 1 26 to rotate. The rotating shaft 26 drives the two bevel gears 27 to rotate. The rotating shaft 3 28 and the two turntables 29 are driven by the two bevel gears 27. Then, under the action of the two pull rods 34, the two turntables 29 rotate to make the two moving rods 31 and the two sliders 30 move up and down continuously. Since the slider 30 is embedded in the slide groove, the swing rod 20 can be swung continuously with the rotating shaft 19 as the rotation axis when the slider 30 moves up and down, thereby making the two warning signs 21 swing.

[0067] The use process of the present invention is as follows: when in use, the section of railway construction and maintenance is input into the maintenance section input module 3, and then the data transmission module 4 transmits the input information to the intelligent retrieval transmission module 5. Since the train running time storage library 2 stores the train's itinerary and the time of passing each station, the intelligent retrieval transmission module 5 can then retrieve the train information passing through the construction and maintenance section and the time of passing through the section from the train running time storage library 2, and then the intelligent editing module 6 can confirm at what time to remind the construction personnel according to the time when the train passes through the section. After confirming the reminder time, the central processor 1 can control the broadcast reminder module 15 to work, and then the broadcast reminder module 15 can broadcast how many minutes a train will pass through the section, thereby realizing the first warning;

[0068] At the same time, the train approaching sensing module 7 can sense the distance between the train and the construction and maintenance section. When sensing, the Beidou automatic positioning module 8 uses the Beidou positioning method to obtain the real-time distance between the train and the construction and maintenance section. The radio detection module 9 uses the radio detection method to obtain the real-time distance between the train and the construction and maintenance section. The intelligent ranging module 10 uses the ultrasonic ranging method to obtain the real-time distance between the train and the construction and maintenance section. With these three ranging methods, the real-time distance between the train and the construction and maintenance section can be accurately known. In addition, the safety threshold setting module 11 stores how far the train is from the construction and maintenance section when the construction workers need to evacuate the construction site. When the distance between the train and the construction and maintenance section reaches the set distance, the wearable vibration reminder module 13 and the intelligent reminder module 14 will remind the construction workers that a train is about to arrive, so that a second early warning can be achieved.

[0069] Due to the different construction scopes, when the construction scope is large, it is necessary to notify the construction workers to evacuate when the train is farther away from the construction site. A threshold change module 12 is designed so that the distance can be changed according to the construction scope. A security authentication module 17 is also designed so that when the distance is changed, the identity of the changer can be authenticated to prevent the security threshold from being maliciously changed. A security protection module 16 is also designed to protect the intelligent editing module 6 from being illegally invaded, thereby preventing the time to remind the construction workers from being maliciously changed.

[0070] When the intelligent prompt module 14 is in use, it controls the motor 1 24 to work, the motor 1 24 works to drive the shaft 2 25 to rotate, the shaft 2 25 rotates to drive the two bevel gears 1 26 to rotate, the two bevel gears 1 26 rotate to drive the two bevel gears 2 27 to rotate, the two bevel gears 2 27 rotate to drive the two shafts 3 28 and the two turntables 29 to rotate, and then under the action of the two pull rods 34, the two turntables 29 rotate to make the two moving rods 31 and the two sliders 30 move up and down continuously. Since the sliders 30 are embedded in the slide slots, the sliders 30 can move up and down when they move up and down. The swing rod 20 is made to swing continuously with the rotating shaft 19 as the rotating axis, so that the two warning signs 21 are made to swing, and at the same time, the two warning lights 22 will also flash, so that the construction personnel can be reminded that the train is approaching and they need to evacuate. When the motor 1 24 is working, the motor 2 38 is controlled to work, so that the reciprocating screw 39 can be rotated, so that the sliding seat 40 is continuously moved up and down, and then the shell 18 is continuously moved up and down, so that the warning sign 21 can be continuously moved up and down when swinging, so that the prompting effect can be improved, and the early warning effect can be guaranteed.
