[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0028] This utility model provides a bridge collision safety alarm system, including an information acquisition module 1, a signal transmission module, an on-site emergency alarm module 3, and an electric lifting gate 4.

[0029] The information acquisition module 1 includes sensors, including a vibration sensor 10, an ultrasonic sensor 11, an infrared sensor 12, and a vision sensor 13. The vibration sensor 10 is built into the bridge, while the ultrasonic sensor 11, infrared sensor 12, and vision sensor 13 are installed on both sides of the bridge. The vision sensor 13 can be a binocular sensor to facilitate the calculation of the ship's three-dimensional coordinates; the binocular sensor is installed in the middle of the side of the bridge. The information acquisition module 1 is continuously active to ensure a rapid response in emergencies. At the moment of collision between the ship and the bridge, the built-in vibration sensor 10 will immediately activate, quickly capturing the vibration data of the bridge. Simultaneously, the ultrasonic sensor 11, infrared sensor 12, and vision sensor 13 installed on the bridge will record every detail of the entire collision process. Once the data acquisition is complete, this valuable information can be uploaded to a cloud database and stored in an orderly manner according to certain rules for further in-depth analysis and research. By using sensors, this invention can immediately trigger the on-site emergency alarm module 3 the instant a ship hits the bridge deck; this rapid response mechanism can immediately alert bridge drivers, enabling them to make accurate judgments and reactions in a timely manner, thereby effectively avoiding or mitigating possible accidents.

[0030] The signal transmission and processing module 2 includes a signal transmitter 20, a signal receiver 21, a storage device 22, and a signal processor 23. The information acquisition module 1, the on-site emergency alarm module 3, and the electric gate 4 are connected to the signal processor 23. The signal processor 23 is connected to the signal transmitter 20 and the storage device 22. The signal transmitter 20 is communicatively connected to the signal receiver 21. The signal transmission module activates immediately after an accident occurs. Its main task is to rapidly transmit relevant accident information to the bridge management and various emergency response units. This ensures they receive accident information promptly, enabling them to take swift action and conduct search and rescue operations to minimize potential losses and impacts.

[0031] The on-site emergency alarm module 3 includes a light strip 30, a buzzer 31 and a display screen 32. The light strip 30 is installed on both sides of the bridge; the display screen 32 is installed on the bridge tower of the bridge and beside the electric lifting gate 4. In the event of an emergency, this module will be immediately activated. The light strips 30 on both sides of the bridge will continuously emit red light to attract the attention of passing people; at the same time, the buzzer 31 will emit continuous alarm sounds to remind people of safety in the form of sound. In addition, the access gates at both ends of the bridge will be blocked by the electric lifting gate 4 to prevent people from entering the dangerous area; at the same time, the display screen 32 above the bridge will display a warning signal to convey the current emergency situation to people visually, ensuring the timely transmission of information and the safety of people. Once an accident occurs, the sensors will immediately start working to collect data at the accident site. These data are quickly uploaded to the storage device 22 through the signal transmitter 20. In the storage module, the data will be classified and stored, and in-depth analysis and learning will be carried out. The purpose of this process is to learn lessons from accidents, optimize safety measures, thereby effectively reducing the likelihood of similar accidents occurring in the future and ensuring the safety and smoothness of the bridge.

[0032] The electric lifting gate 4 is installed at the access gates at both ends of the bridge and includes a gate post 42 and a gate rod 41 installed on the gate post 42. The gate rod 41 remains open under normal circumstances and is in the closed state when a collision occurs. There are two gate posts 42, which are respectively installed on both sides of the access gate. One gate rod 41 is installed on each gate post 42 to block vehicles entering and leaving the bridge respectively. A blocking device is provided on the gate post 42 and an ultrasonic sensor 11 is installed. A groove is provided on the gate post 42, and a first electromagnet is installed in the groove. A second electromagnet that mutually attracts with the first electromagnet is installed on the blocking device. The blocking device is embedded in the groove and is connected to the groove through a spring and a telescopic rod. The length of the spring is the set warning length. The first electromagnet and the second electromagnet include a powered-on state and a powered-off state. A clamping block is provided on one side of the gate post 42 close to the gate rod 41. The width of the gate rod 41 is d, and the clamping range of the clamping block is D1~D2, where D1 < d < D2. When an emergency rescue vehicle needs to pass through, the gate rod 41 is manually lifted and clamped by the clamping block.

[0033] The ultrasonic sensor 11 detects the distance between the vehicle and the gate post 42. When the distance between the gate post 42 and the vehicle is greater than or equal to twice the set warning length, the first electromagnet and the second electromagnet are in the powered-on state; otherwise, the first electromagnet and the second electromagnet are in the powered-off state. When the gate rod 41 is in the closed state and the first electromagnet and the second electromagnet are in the powered-off state, the blocking device pops out to block the vehicle. A collision button is also installed on the blocking device. When the vehicle collides with the collision button, the buzzer of the on-site emergency alarm module 3 is activated.

[0034] This invention constructs a comprehensive, multi-layered monitoring and alarm system through the coordinated operation of an information acquisition module 1, a signal transmission module, an on-site emergency alarm module 3, and an electric gate 4. It can significantly improve emergency response capabilities after an accident and ensure the safety of life and property of bridge drivers through a series of effective alarm measures.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
