Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic safety monitoring equipment, in particular to a novel highway tunnel traffic safety monitoring and early warning system. Background Art
[0002] The highway tunnel traffic safety monitoring and early warning system is a comprehensive technical system designed to ensure the safe operation of traffic in highway tunnels. The system provides early warning and emergency processing functions by real-time monitoring of traffic conditions, environmental parameters and equipment status in the tunnel, thereby effectively preventing accidents and ensuring the safety of vehicles and personnel. Its components generally include: monitoring subsystem, early warning subsystem, communication subsystem and control center. Through the coordinated work of these components, the tunnel traffic safety monitoring and early warning system can comprehensively monitor the safety conditions in the tunnel, promptly identify and deal with potential risks, and ensure traffic safety.
[0003] Although the existing highway tunnel traffic safety monitoring and early warning system can monitor and warn of traffic conditions, it lacks a certain blocking capability. When a dangerous situation occurs in the tunnel, if the vehicles entering the tunnel are not blocked in time, it may cause traffic jams, further increase losses, and cause serious safety accidents. Therefore, it is necessary to develop a highway tunnel traffic safety monitoring and early warning system with a blocking function. Utility Model Content
[0004] The purpose of the utility model is to provide a novel highway tunnel traffic safety monitoring and early warning system, which solves the problem that the traditional highway tunnel traffic safety monitoring and early warning system does not have a blocking function, resulting in more serious accidents.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] The utility model provides a novel highway tunnel traffic safety monitoring and early warning system, comprising: a PLC controller; an environmental monitoring module, which is connected to the PLC controller; a communication module, which is connected to the PLC controller; an alarm module, which is connected to the PLC controller; a blocking module, which is connected to the PLC controller, and comprises a traffic indicator light, a water curtain wall and an entrance display.
[0007] Furthermore, the environmental monitoring module includes a gas sensor, a smoke sensor, a temperature and humidity sensor, a flow sensor and an image collector.
[0008] Furthermore, the communication module includes a communication optical fiber and a LoRa wireless transmitter.
[0009] Furthermore, the warning module includes an audible and visual alarm and a warning broadcaster.
[0010] Technical effects of this utility model:
[0011] Compared with the existing technology, the new highway tunnel traffic safety monitoring and early warning system involved in the utility model greatly improves the security of communication and ensures the transmission of traffic signal data by setting up dual communication modes of communication optical fiber and LoRa wireless transmitter, providing protection for safe traffic; by setting up a blocking module, it effectively avoids the influx of subsequent vehicles after a dangerous situation occurs, alleviates the traffic pressure in the tunnel, is conducive to the elimination of dangerous situations in the tunnel, and greatly reduces the losses when an accident occurs. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a structural diagram of the utility model. DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification.
[0014] Example:
[0015] like Figure 1As shown, a new type of highway tunnel traffic safety monitoring and early warning system described in this embodiment includes: a PLC controller; an environmental monitoring module, which is connected to the PLC controller and includes a gas sensor, a smoke sensor, a temperature and humidity sensor, a flow sensor and an image collector, and is used to monitor the traffic environment in the tunnel to ensure the normal operation of traffic; a communication module, which is connected to the PLC controller and includes a communication optical fiber and a LoRa wireless transmitter, and is used to transmit environmental data in the tunnel to a terminal device so that staff can remotely monitor the traffic environment in the tunnel; by setting up a dual communication mode of communication optical fiber and LoRa wireless transmitter, the security of communication is greatly improved, the transmission of traffic signal data is guaranteed, and safe traffic is provided; warning A warning module is provided, which is connected to the PLC controller. The warning module includes an audible and visual alarm and a warning broadcaster. The warning module is used to convey the environmental conditions in the tunnel to the vehicles in the tunnel, so that the people in the tunnel can know the occurrence of dangerous situations in the first time; a blocking module is connected to the PLC controller, and includes a traffic light, a water curtain wall and an entrance display. The traffic light, the water curtain wall and the entrance display are all installed at the entrance of the tunnel. The traffic light and the entrance display are used to convey the traffic conditions in the tunnel to the vehicles entering the tunnel. The water curtain wall is used to form a water curtain at the tunnel entrance when a dangerous situation occurs in the tunnel to block the entry of subsequent vehicles. By setting the blocking module, the influx of subsequent vehicles after the dangerous situation occurs is effectively avoided, the traffic pressure in the tunnel is relieved, it is conducive to the removal of the dangerous situation in the tunnel, and the loss when the accident occurs is greatly reduced.
[0016] How it works
[0017] When monitoring a highway tunnel, the environmental monitoring module detects the traffic environment inside the tunnel. When the data detected by one or more sensors is abnormal, the PLC controller controls the alarm module to start. The sound and light alarm and warning broadcaster inform the personnel in the tunnel of the danger and notify them to leave as soon as possible and in an orderly manner. Then the PLC controller starts the blocking module. The traffic lights and entrance displays inform the vehicles about to enter the tunnel of the situation inside the tunnel. The water curtain wall generates a water curtain to block the continued influx of subsequent vehicles and prevent the traffic situation from further deteriorating. Finally, the PLC controller sends the danger information to the device terminal via the communication optical fiber and LoRa wireless transmitter, informing the staff to deal with the danger in the tunnel as soon as possible.
[0018] Utilizing the technical solution described in the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the scope of protection of the present invention.
