[0044] With the development of transportation, there are more and more bridges. Due to the increase of bridges, bridge aging, geological disasters, floods and other reasons, bridges often break, collapse, and are washed away, which pose a great threat to traffic safety and even cause major traffic accidents. In view of this, it is necessary to monitor bridges in real time, take corresponding measures in time when problems are found, and avoid accidents.

[0045] Currently, bridge monitoring mostly relies on personnel inspections, which are unable to detect bridge problems or safety hazards in a timely and accurate manner.

[0046] The invention provides an automatic bridge safety detection system.

[0047] Reference Figure 1 In one embodiment, the automatic bridge safety detection system includes:

[0048] A safety detection component 10 is provided on the bridge, and is used to detect deformation and displacement of the bridge and output corresponding deformation signals and displacement signals;

[0049] A processor 20 is disposed on the bridge, the processor 20 is in communication with the safety detection component 10, and the processor 20 is used to output an alarm signal when it is determined that the bridge is abnormal according to the deformation signal or displacement signal output by the safety detection component 10;

[0050] The alarm component 30 is arranged on the bridge, and the alarm component 30 is in communication connection with the processor 20, and the alarm component 30 is used for working when receiving the alarm signal.

[0051] In this embodiment, the safety detection component 10 can be composed of devices for detecting deformation and displacement, such as detecting the deformation of the bridge through a strain gauge, or detecting the pressure caused by the deformation of the bridge through a pressure sensor, thereby outputting the corresponding deformation signal to the processor 20. The displacement of the bridge can also be detected by a displacement sensor. There are many types of displacement sensors, which can be selected according to actual conditions, such as a Hall displacement sensor: its measurement principle is to keep the excitation current of the Hall element unchanged and make it move in a magnetic field with a uniform gradient, and the displacement moved is proportional to the output Hall potential. The larger the magnetic field gradient, the higher the sensitivity; the more uniform the gradient change, the closer the relationship between the Hall potential and the displacement is to linear. The pier displacement sensor 121 transmits the measured displacement result to the processor 20 for processing. When the displacement exceeds a certain value, the processor 20 determines that the bridge is abnormal, outputs an alarm signal, and can also perform relevant emergency processing. The sensor or other detection device constituting the safety detection component 10 can be set at a position where the bridge is prone to deformation and makes the bridge prone to safety hazards. The processor 20 may be a digital signal processor 20 (DSP), a programmable logic device (PLD), a field programmable gate array (FPGA), a microprocessor 20, an MCU or other electronic components. The processor 20 may determine whether the bridge is abnormal based on the deformation signal or the displacement signal. For example, the processor 20 stores the safety range of the deformation value and the displacement value of the bridge. The processor 20 obtains the deformation value and the displacement value of the bridge based on the deformation signal and the displacement signal. When the deformation value or the displacement value of the bridge exceeds the safety range, it is determined that the bridge is abnormal, indicating that the bridge has a safety hazard. At this time, the processor 20 outputs an alarm signal to the alarm component 30; and the processor 20 may continuously receive the deformation signal and the displacement signal output by the safety detection component 10 to realize real-time monitoring, or may receive the deformation signal and the displacement signal output by the safety detection component 10 at intervals, and the specific interval time may be set according to the actual situation. Furthermore, the judgment of bridge abnormality can be more detailed, such as dividing into multiple abnormality levels, and different bridge deformation values ​​and bridge displacement values ​​correspond to different abnormality levels. The higher the abnormality level, the more likely it is to cause a safety accident. The specific abnormality level and the corresponding bridge deformation value and bridge displacement value can be set according to the actual situation. The alarm component 30 can be composed of a speaker or a lamp, and the speaker emits sound or the lamp emits light to remind people or vehicles that are about to pass the bridge. For example, the speaker emits voice information such as "bridge danger" and the lamp emits red light. The specific alarm method can also be implemented by other devices, which is not limited here.It should be noted that, in this embodiment, the devices in the safety detection component 10 and the alarm component 30 can also be connected to the processor 20 by wire to ensure the communication quality. Specifically, wireless communication connection or wired communication connection can be adopted, which can be set according to actual conditions.

[0052] The technical solution of the present invention constitutes an automatic detection bridge safety system through a safety detection component 10, a processor 20 and an alarm component 30, wherein the safety detection component 10 is arranged on the bridge, the safety detection component 10 can detect the deformation and displacement of the bridge, and output the corresponding deformation signal and displacement signal to the processor 20; the processor 20 is arranged on the bridge, the processor 20 is connected in communication with the safety detection component 10, and the processor 20 is used to output an alarm signal to the alarm component 30 when it is determined that the bridge is abnormal according to the deformation signal or displacement signal output by the safety detection component 10; the alarm component 30 is arranged on the bridge, the alarm component 30 is connected in communication with the processor 20, and the alarm component 30 can work when receiving the alarm signal, thereby reminding vehicles and pedestrians that the bridge has safety hazards. In this way, the automatic detection bridge safety system of the technical solution of the present invention can monitor the safety of the bridge in real time, and output an alarm signal to remind when an abnormality occurs, thereby improving the safety of the bridge.

[0053] Reference Figure 2 In one embodiment, the bridge has a bridge deck and a bridge pier, and the safety detection component 10 includes:

[0054] A deformation detection module 11 is arranged on the bridge deck and the bridge pier and is in communication connection with the processor 20. The deformation detection module 11 is used to detect the deformation of the bridge deck and the bridge pier and output corresponding bridge deck deformation signals and bridge pier deformation signals to the processor 20;

[0055] The displacement detection module 12 is disposed on the bridge pier and is in communication connection with the processor 20 . The displacement detection module 12 is used to detect the displacement of the bridge pier and output a corresponding bridge pier displacement signal to the processor 20 .

[0056] In this embodiment, the deformation detection module 11 can be set on the bridge deck and the piers. The bridge deck can be used for vehicles and pedestrians to pass through, and the piers are vertical components that support the bridge deck and the bridge structure. The deformation detection module 11 is set on the bridge deck and the piers, and the deformation of the bridge deck and the piers can be detected, and the corresponding bridge deck deformation signal and the pier deformation signal are output to the processor 20. If the deformation is serious, it may cause a safety accident. The specific standard for whether the deformation is serious can be set according to the actual road conditions; and the bridge deck and the piers can also be set to different standards for judging the deformation. In this embodiment, the displacement detection module 12 is set on the piers. It can be understood that the piers may be displaced due to soil settlement or other geological factors, or due to temperature changes, load changes, wind changes, etc. Therefore, the displacement of the piers within a certain range will not cause safety accidents. The specific safety range of displacement can be set according to the environment around the bridge. If the displacement exceeds the safety range, a safety accident may occur. Therefore, when any of the bridge deck deformation value, pier deformation value or pier displacement value obtained according to the bridge deck deformation signal, pier deformation signal or pier displacement signal exceeds the corresponding set safety range, the processor 20 can output an alarm signal to the alarm component 30.

[0057] Reference Figure 3 In one embodiment, the bridge deck has a plurality of connections, the bridge pier has a plurality of connections, and the deformation detection module 11 includes:

[0058] A plurality of bridge stress deformation sensors 111, each of which is disposed at a connection of the bridge deck and is communicatively connected to the processor 20, and the bridge stress deformation sensor 111 is used to detect deformation of the connection of the bridge deck and output a corresponding bridge deck deformation signal to the processor 20;

[0059] Multiple pier stress and deformation sensors 112, each of which is arranged at a connection point of the pier and is communicatively connected to the processor 20, and the pier stress and deformation sensor 112 is used to detect the deformation of the connection point of the pier and output a corresponding pier deformation signal to the processor 20.

[0060] In this embodiment, a plurality of bridge stress deformation sensors 111 can be set at a plurality of connections of the bridge deck. The connection of the bridge deck can be the connection between the bridge deck and the bridge deck, or the connection between the bridge deck and the pier, bridge and waterproof layer and other structures. The connection at the connection can detect whether the connection of the bridge deck is stable. If the deformation value of the connection of the bridge deck is too large, the connection may be loose, which may lead to the occurrence of safety accidents. The bridge stress deformation sensor 111 can also be set at the support point of the bridge deck and other locations that are prone to deformation and make the bridge prone to safety hazards. The pier stress deformation sensor 112 is set at a connection of the pier. The connection of the pier can be the connection between the pier and the bridge deck, or the connection between the pier and the foundation or waterproof layer and other structures. The pier stress deformation sensor 112 is set at the connection to detect whether the connection of the pier is stable. If the deformation value of the pier connection is too large, it may cause safety accidents. The pier stress deformation sensor 112 can also be set at the cement pouring interface of the pier and other locations that are prone to deformation and make the bridge prone to safety hazards.

[0061] Reference Figure 3 In one embodiment, the bridge has a plurality of piers, and the displacement detection module 12 includes:

[0062] Multiple pier displacement sensors 121, each of which is disposed on a pier and is communicatively connected to the processor 20, and the pier displacement sensor 121 is used to detect the displacement of the pier and output a corresponding pier displacement signal to the processor 20.

[0063] In this embodiment, the pier displacement sensor 121 can be set on the main body of the pier. There are many types of displacement sensors, which can be selected according to actual conditions, such as a Hall displacement sensor: its measurement principle is to keep the excitation current of the Hall element unchanged and make it move in a magnetic field with uniform gradient, and the displacement moved is proportional to the output Hall potential. The larger the magnetic field gradient, the higher the sensitivity; the more uniform the gradient change, the closer the relationship between the Hall potential and the displacement is to linearity. The pier displacement sensor 121 transmits the measured displacement result to the processor 20 for processing. When the displacement exceeds a certain value, the processor 20 drives the alarm and performs relevant emergency processing. For multiple piers of the bridge, a pier displacement sensor 121 can be set for each pier. Furthermore, for piers at different positions, their safe displacement ranges may also be different. Therefore, it is necessary to set the safe displacement range corresponding to each pier according to the actual environmental conditions. The processor 20 can output an alarm signal to the alarm component 30 when it is determined that the displacement value of the corresponding pier exceeds the safe displacement range according to the pier displacement signal output by any pier displacement sensor 121.

[0064] Reference Figure 4In one embodiment, the bridge has piers, and the safety detection component 10 further includes:

[0065] The water flow detection module 13 is arranged on the bridge pier and is communicatively connected with the processor 20. The water flow detection module 13 is used to detect the water flow velocity and water level around the bridge pier, and output corresponding water flow velocity signals and water level signals to the processor 20. The processor 20 is used to output an alarm signal to the alarm component 30 when it is determined that an abnormality occurs in the bridge according to the water flow velocity signal or the water level signal.

[0066] In this embodiment, a water flow detection module 13 is provided on the bridge pier to detect the water flow velocity and water level around the bridge pier. It is understandable that a higher water flow velocity may cause the sediment on the riverbed or the bottom of the water body to be washed away, thereby causing erosion and instability of the bridge pier or foundation, and a higher water flow velocity may generate dynamic water pressure on the bridge structure, especially during floods. Large water flow can cause strong hydrodynamic effects, exerting additional forces on the bridge deck and piers. A higher water level will change the hydrodynamic characteristics, increase the stress on the bridge deck and piers, and may cause the water flow to impact the bridge body; and the rising water level may cause the soil around the river bank or piers to be washed away and eroded, affecting the lateral support force of the bridge. Therefore, the water flow velocity and water level around the bridge pier are detected by the water flow detection module 13, and then the corresponding water flow velocity signal and water level signal are output to the processor 20. The processor 20 can be preset with safety values ​​of water flow velocity and water level. When the real-time water flow velocity or water level exceeds the safety value according to the water flow velocity signal and water level signal output by the water flow detection module 13, the processor 20 can output an alarm signal to the alarm component 30. For multiple bridge piers of the bridge, a water flow detection module 13 can be set corresponding to each bridge pier, and the corresponding water flow velocity and water level judgment standard can be set according to the actual water flow conditions in the corresponding area of ​​each bridge pier.

[0067] Reference Figure 4 In one embodiment, there are multiple piers, and the water flow detection module 13 includes:

[0068] A plurality of water flow velocity sensors 131 are arranged on the bridge piers and are in communication connection with the processor 20. The water flow velocity sensors 131 are used to detect the water flow velocity around the bridge piers and output corresponding water flow velocity signals to the processor 20.

[0069] A plurality of water level sensors 132 are disposed on the bridge piers and are in communication connection with the processor 20 . The water level sensors 132 are used to detect the water level around the bridge piers and output corresponding water level signals to the processor 20 .

[0070] In this embodiment, multiple water flow rate sensors 131 and multiple water level height sensors 132 may be provided corresponding to multiple bridge piers of the bridge. The water flow rate sensor 131 is provided at the underwater part of the bridge pier, and mainly measures the water flow rate around the bridge pier. The water flow rate sensor 131 has an impeller. The faster the water flow, the greater the driving force on the impeller, and the faster the impeller rotates. The rotation of the impeller generates electromotive force. The greater the water flow, the faster the impeller rotates, and the greater the electromotive force generated. The water flow rate sensor 131 transmits the measured data, i.e., the water flow rate signal, to the processor 20. When the flow rate exceeds a certain value and the processor 20 determines that a threat has been posed to the bridge, the safety processor 20 outputs an alarm signal and performs relevant emergency processing. The water level sensor 132 can be vertically set on the bridge pier. The water level drives the contacts of the sliding resistor to move up and down, converting the water level change into a resistance value, and transmitting the result to the processor 20. The processor 20 can also judge whether a threat to the bridge is caused according to the water flow velocity and the water level value. When it is judged that the safety of the bridge is threatened, the processor 20 drives the alarm and performs relevant emergency processing; specifically, a mapping table of water flow velocity, water level value and safety value can be preset in the processor 20, and the mapping table can be used to judge whether the current water flow velocity and water level pose a threat to the bridge.

[0071] In one embodiment, the safety detection component 10 further includes:

[0072] A plurality of cameras are communicatively connected with the processor 20, wherein the cameras are used to photograph the bridge and output corresponding bridge image signals to the processor 20, and the processor 20 is used to output an alarm signal to the alarm component 30 when determining that an abnormality occurs in the bridge according to the bridge image signal.

[0073] In this embodiment, multiple cameras can be installed at appropriate locations so that the cameras can take high-definition photos of the bridge deck, the supporting foundation of the bridge, the piers, etc., and transmit the images to the processor 20 for processing. The processor 20 can analyze the camera image data to determine whether there are abnormal phenomena such as fracture marks, collapse, deformation, etc. on the bridge deck. When these phenomena occur, an alarm signal can be output to the alarm component 30, and relevant emergency treatment can be performed. In addition, the camera can also be provided with a haze penetration video module, so that images or videos polluted by haze can be processed to improve the clarity and visibility of the image, so as to prevent the image of the bridge from being unable to be clearly photographed and recognized in foggy weather.

[0074] Reference Figure 5 In one embodiment, the alarm component 30 includes:

[0075] An alarm speaker 31 is provided on the bridge and is in communication with the processor 20. The alarm speaker 31 is used to play an alarm message when receiving an alarm signal output by the processor 20;

[0076] The safety warning light 32 is arranged on the bridge and is in communication connection with the processor 20 . The safety warning light 32 is used to work when receiving an alarm signal output by the processor 20 .

[0077] In this embodiment, the alarm speaker 31 can play an alarm message when receiving the alarm signal output by the processor 20, which can be a voice message such as "bridge danger", so as to remind pedestrians or vehicles; the safety warning light 32 can also remind pedestrians, and it also has a reminder effect for people who cannot accurately hear the sound played by the alarm speaker 31 in the car. The safety warning light 32 can use red light or other colors of light for warning.

[0078] In one embodiment, the automatic bridge safety detection system further comprises:

[0079] The road gate is arranged at one end of the bridge and is in communication connection with the processor 20 . The road gate is used to close upon receiving an alarm signal output by the processor 20 .

[0080] In this embodiment, a road gate is set at one end of the bridge, and the road gate can be closed when receiving an alarm signal output by the processor 20 to prevent pedestrians or vehicles from entering the bridge deck with potential safety hazards. The road gate remains open when the alarm signal output by the processor 20 is not received. Further, road gates can be set at both ends of the bridge.

[0081] In one embodiment, the automatic bridge safety detection system further comprises:

[0082] A communication module is arranged on the bridge and is in communication connection with the processor 20. The communication module is used to communicate with the cloud server. The communication module is also used to transmit the alarm signal output by the processor 20 to the cloud server.

[0083] In this embodiment, the communication module can complete the communication between the processor 20 and the cloud server, transmit the alarm signal output by the processor 20 and the bridge-related detection data to the cloud server; and can obtain data from the cloud server, such as the standard range value for bridge safety judgment.
