[0026] In order to facilitate understanding of the technical solution of the present utility model, the following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 、 2 As shown, a rotating, retractable tunnel emergency telephone broadcasting device 10 includes a chassis body 11, a cover plate 12, and a heat dissipation hole 13. The cover plate 12 is hingedly connected to one end of the front side of the chassis body 11. The cover plate 12 has a heat dissipation hole 13 on its front side. A chain-type electric window opener 20 is installed within the chassis body 11, which is used to open the cover plate and control the opening angle according to control. Specifically, a partition is provided at the bottom of the chassis body 11. The partition and the bottom plate of the chassis body 11 form a cavity that accommodates the housing 22 of the chain-type electric window opener 20.

[0028] In order to fix the chain-type electric window opener 20, the shell 22 is provided with window opener mounting holes 29 on the left and right sides, and the side wall of the cavity of the chassis body 11 is provided with a chassis mounting hole 14 corresponding to the position of the window opener mounting hole 29, and then the chain-type electric window opener 20 is fixed in the cavity of the chassis body 11 by screws.

[0029] like Figure 2-5 The following describes the structure of the chain-type electric window opener 20 and its connection to the cover plate. The chain-type electric window opener 20 includes a housing 22, a chain 24, a control circuit board 25, a transmission gear 26, a chain guide 27, a sensor 28, and a drive mechanism 23. The control circuit board 25 controls the chain travel via the sensor 28. One end of the chain 24 is fixed to the chain guide 27, while the other end extends outward from the side wall of the housing 22. A mounting bracket 21 is provided at the end of the chain 24, which is connected to the cover plate 12 away from the hinge end via this mounting bracket 21.

[0030] The driving mechanism 23 includes a motor 23A, a worm 23B at the output end of the motor and a worm wheel 23C matched therewith. The worm wheel is meshingly connected to a transmission gear 26 and a chain 24 . The chain 24 is limited in movement by a chain guide 27 .

[0031] The operating principle is as follows: the control circuit board receives a signal to open the cover, which in turn drives the motor, worm gear, and gears to drive the chain 24 out of the housing. As the chain extends, the cover rotates around the hinge, opening. When the angle reaches a certain point, the control signal stops the motor, and the cover stops at that angle. Because the chain, turbine, and gears are interconnected, the cover is rigidly fixed, preventing it from being rotated by the airflow caused by the vehicle.

[0032] like Figure 6 、 7 As shown, an emergency parking strip integrated control system is installed in the chassis of a rotating and retractable tunnel emergency telephone broadcasting device. The emergency parking strip integrated control system includes a remotely located server terminal 60, as well as an on-site detection camera module 30, a parking strip photoelectric identification module 40, and an emergency parking strip controller 50. The emergency parking strip controller 50 controls and connects to the parking strip photoelectric identification module 40. The detection camera module 30 and the emergency parking strip controller 50 are in communication with the remotely located server terminal 60. The detection camera module 30 is connected to the server terminal 60 via Wi-Fi or 4G card wireless communication.

[0033] The emergency parking belt controller 50 is a PLC that communicates with the Modbus TCP protocol. It controls the parking belt photoelectric identification module 40 through I / O. The emergency parking belt controller 50 is connected to the server terminal 60 through a twisted pair cable. Thus, the emergency parking belt controller 50 establishes a TCP connection with the server terminal 60 as a client and communicates with the server. Request sending: The client emergency parking belt controller 50 sends a request message to the server, requesting to read or write data. The request message contains a transaction identifier, a protocol identifier, a length field, a unit identifier, a function code, and related data and operation parameters. Response receiving: After the server receives the request from the client of the emergency parking belt controller 50, it performs the corresponding operation according to the requested function code and generates a response message. The response message contains a transaction identifier, a protocol identifier, a length field, a unit identifier, a function code, and the result data of the request. The remote I / O module of the Modbus TCP protocol can use the Aimoxun Modbus TCP distributed IO module, such as the MT2A module, to connect to the PLC.

[0034] The vehicle lane photoelectric identification module 40 includes emergency lights 41, which are configured in yellow and green. These lights are connected to the PLC control of the emergency lane controller 50. When a vehicle is entering the emergency lane, they flash continuously in yellow, and when no vehicle is in use, they flash green. Multiple emergency lights 41 are evenly distributed along the dividing line between the emergency lane and the normal lane, facilitating vehicle guidance and providing safety warnings in the emergency lane.

[0035] The vehicle-mounted photoelectric identification module 40 also includes a white light strip 42 for displaying the outline of the emergency stop lane. The light strip 42 is located along the entrance, emergency stop, and exit approaches, close to the inner wall of the tunnel. The light strip 42 is white and has a height of 2-3 meters.

[0036] The control circuit board 25 of the chain-type electric window opener 20 is connected to the emergency stop belt controller 50 via the Modbus TCP protocol.

[0037] The principle is as follows: when the detection camera module 30 detects a vehicle entering the emergency stop lane, the server terminal 60 sends a control signal to the PLC of the emergency stop lane controller 50. The PLC then controls the vehicle's photoelectric identification module 40, including the emergency lights 41 and position marker lights 42, to illuminate warning lights. When inspection or maintenance is required, the server terminal 60 sends a control signal to the control circuit board 25 of the chain-type electric window opener 20, activating the motor to extend the chain. When inspection is complete, the motor retracts the chain. These two measures significantly enhance the safety of the emergency stop lane system.

[0038] The above are only preferred embodiments of the present invention. The scope of protection of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be regarded as the scope of protection of the present invention.
