Therefore, the directional terms used are used for illustration, not for limitation of the utility model.

[0041] The utility model relates to an active early warning system for bridge collision risk, specifically an active early warning system for protecting the safety of bridges and people and vehicles passing through the bridge deck. The equipment in the active early warning system of the utility model is separately arranged at various places on the bridge.

[0042] Figure 1This is a schematic diagram of the active warning system equipment of the utility model. A common top view of a bridge structure is as follows: Figure 1 As shown, the bridge spans the river and is provided with a two-way lane, the left side of the bridge is the upstream of the waterway, and the right side of the bridge is the downstream of the waterway. The active early warning system of the utility model includes a master control system 10 (not shown) and a plurality of device nodes, each of which is connected to the master control system through its internal network transmission device 20, and each device node is arranged at a different position of the bridge.

[0043] Figure 2 The figure is a schematic diagram of equipment connection in the active early warning system of the utility model. The equipment nodes include a first equipment node A1, a second equipment node A2, a third equipment node A3, and a fourth equipment node A4.

[0044] Among them, a first equipment node A1 is set in the middle of the bridge facing the upstream direction of the waterway. Figure 2 As shown in part (a), the first device node A1 includes a network transmission device 20, a switch signal host 30, a channel warning screen 40, a ship scanning radar 50, and multiple sets of channel-specific cameras 60. The channel warning screen 40 is connected to the switch signal host 30, and the switch signal host 30, the ship scanning radar 50, and the channel-specific camera 60 are connected to the network transmission device 20. The channel warning screen 40, the ship scanning radar 50, and the channel-specific camera 60 in the first device node A1 are facing the upstream direction of the channel. The ship scanning radar 50 and the channel-specific camera 60 are used to record the trajectory of the ship in the upstream direction of the channel, and the generated radar data and video data are sent to the master control system 10 through the network transmission device 20. If the master control system 10 determines that there is a risk of sending a collision, the master control system 10 sends a signal to the switch signal host 30 through the network transmission device 20, and the switch signal host 30 controls the channel warning screen 40 to light up a warning slogan, such as displaying "High risk of incoming ships".

[0045] A second equipment node A2 is arranged in the middle of the bridge facing the downstream direction of the waterway. Figure 2As shown in part (b), the second device node A2 is configured with all the devices in the first device node A1, except that the ship scanning radar 50 and the channel-specific camera 60 are used to record the ship trajectory in the downstream direction of the channel. In addition, the second device node A2 also includes a high-frequency broadcasting device 70 and an AIS signal acquisition device 80. The high-frequency broadcasting device 70 is connected to the switch signal host 30. If the master control system 10 determines that there is a risk of sending a collision, the master control system 10 sends a signal to the switch signal host 30 through the network transmission device 20. The switch signal host 30 controls the high-frequency broadcasting device 70 to work and broadcast a high-frequency warning to the ship. For example, the reminder information is set to: "Ship No. XX, your ship behavior is high-risk and is about to collide with the bridge. Please stop immediately!". The AIS signal acquisition device 80 is connected to the network transmission device 20. The AIS signal acquisition device 80 is a ship automatic identification system for automatically receiving and sending signals from other ships, land base stations and satellites.

[0046] The third device nodes A3 are set at certain intervals along the bridge direction. Preferably, the third device nodes A3 are set at certain intervals on the lanes in both directions of the bridge. The interval distance can be determined according to the length of the bridge, the traffic flow, the flow of people, etc. For example, it can be set to 200 meters. Figure 2 As shown in part (c), the third device node A3 includes a network transmission device 20, a switch signal host 30, a roadside warning screen 90, and a lane directional speaker 100. The roadside warning screen 90 and the lane directional speaker 100 are connected to the switch signal host 30, and the switch signal host 30 is connected to the network transmission device 20. The roadside warning screen 90 and the lane directional speaker 100 in the third device node A3 face the direction of the bridge lane. If the master control system 10 determines that there is a risk of sending a collision, the master control system 10 sends a signal to the switch signal host 30 through the network transmission device 20, and the switch signal host 30 controls the roadside warning screen 90 to light up a warning slogan, such as "A ship collision accident is about to occur on this bridge, please evacuate immediately", and at the same time, the lane directional speaker 100 sounds to remind vehicles and pedestrians on the lane, for example, cyclically broadcasting the warning information "A ship collision accident is about to occur on this bridge, please evacuate immediately!" with a power of more than 120dB.

[0047] A fourth device node A4 is provided at the entrances and exits at both ends of the bridge. Figure 2As shown in part (d), the fourth device node A4 is configured with all the devices in the first device node A1, except that the fourth device node A4 is also provided with a roadside flashing warning light 110, and the roadside flashing warning light 110 is arranged toward the bridge lane. The roadside flashing warning light 110 is connected to the network transmission device 20. If the master control system 10 determines that there is a risk of sending a collision, the master control system 10 sends a signal to the switch signal host 30 through the network transmission device 20, and the switch signal host 30 controls the roadside flashing warning light 110 to light up, and warns vehicles and pedestrians by flashing.

[0048] Preferably, the first device node A1, the second device node A2, the third device node A3, and the fourth device node A4 can also be provided with a UPS emergency power supply device 120, which is used to provide emergency power supply to the devices of each node. When the bridge is hit by a ship, the basic functions such as power supply and transmission are destroyed, the whole bridge is powered off, or some device nodes of the early warning system are damaged by collision, so that the system can still operate normally. In terms of power supply, independent UPS emergency power supply devices 120 are provided in each device node in the system, and after the external power supply is interrupted, it automatically switches to the UPS power supply mode to maintain the normal operation of the devices in the device node.

[0049] The network transmission device 20 is preferably a wireless network transmission device. The network communication structure preferably adopts a mesh topology structure or a star topology structure. Figure 3 The schematic diagram of the mesh topology network is shown in Figure 1. Figure 4 This is a schematic diagram of a star topology network. This type of network has self-healing properties. When the original connection link is damaged, it can automatically establish a new network connection by skipping the damaged point, ensuring that even if some points are missing, it will not affect the normal operation of other devices in the system.

[0050] The waterway warning screen 40 and the roadside warning screen 90 are preferably LED screens.

[0051] After adopting the above bridge collision risk active warning system, when a ship is about to collide with a bridge, the system can use sound, light, electricity and other multi-directional warning methods to remind passing personnel and vehicles to evacuate or turn around and return. At the same time, the system can also add further alarm procedures, such as automatically sending a message to a preset mobile phone number "XX bridge is about to collide with a bridge, please deal with it immediately." to remind the bridge management party that danger is about to occur, or send a distress signal to the police and hospital to speed up the response of relevant departments to the accident. Calculated based on the ship's speed of 8 nautical miles per hour passing through the bridge, the system can provide at least 10 minutes of warning time, which is enough to ensure the safe evacuation of personnel and vehicles on the bridge deck, and can prevent personnel and vehicles from passing after hazards such as bridge rupture occur, avoiding secondary accidents.

[0052] To sum up, the bridge collision risk active warning system of the utility model adopts multi-directional warning methods such as sound, light, and electricity to remind passers-by, bridge workers, vehicles, etc., which can effectively extend the response time of collision accidents, better ensure the evacuation of personnel and vehicles, and protect life safety and property safety.

[0053] Although the present invention has been disclosed as above by the embodiments, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
