[0002] Nowadays, natural disasters such as floods and debris flows pose a serious threat to basic road facilities such as bridges or roads, resulting in frequent bridge or road collapse accidents.

[0003] The existing solutions mainly monitor the condition of bridges through manual inspections and monitoring devices. Once an abnormality is found, corresponding measures are immediately taken, such as closing the bridge and notifying vehicles to detour. In addition, there are also some early warning systems that predict the stability of bridges by detecting parameters such as vibration and displacement of bridges, so as to early warn of possible collapse accidents.

[0029] As Figure 1 shown, the embodiment of the present application provides a landslide monitoring and early warning system, including a main control module 10, a power supply module 20, a plurality of power sockets 30 and an alarm module 50, Figure 1It is exemplified by three power sockets 30. The main control module 10 is electrically connected to the power supply module 20. Each adjacent power socket 30 is connected by a wire, and the wire is pluggably connected to the power socket 30. One of the power sockets 30 is electrically connected to the power supply module 20 and the main control module 10 respectively. The alarm module 50 is connected to the main control module 10.

[0030] Among them, the main control module 10 is used to detect the on-off state of the circuit and is also used to control the alarm module to give an alarm. For example, the main control module can be set near the monitoring object. For example, it can be set at one end or both ends of the monitoring object. For example, the monitoring object can be a bridge, a road, a building, a mountain body, etc., and can be used to warn of landslides, fractures, drops, etc. of the monitoring object.

[0031] The power supply module 20 is used to provide power and is electrically connected to the main control module 10 and a power socket 30 to provide power for the main control module 10 and the power socket 30. For example, the power supply module can generate electricity through renewable energy such as water power, wind power, ocean tides, water pressure difference of dams, solar energy, etc., and by burning coal, oil residue, etc. to provide electrical energy. For example, the power supply module can include dry batteries, generators, solar panels, wind turbines, etc.

[0032] The power socket 30 is set on the monitoring object, and the power sockets 30 can be connected by pluggable wires. One of the power sockets 30 is electrically connected to the power supply module 20 and the main control module 10 respectively. It should be understood that the power socket and the pluggable wire are set on the monitoring object. When the monitoring object is displaced or fractured, the pluggable wire will be disconnected and the circuit will also be disconnected. The main control module 10 learns that the wire is abnormal by detecting the circuit, so as to master the abnormal state of the monitoring object.

[0033] The alarm module 50 is connected to the main control module 10 and is used to give an alarm when the monitoring object is abnormal. For example, the alarm module can be set near the monitoring object. For example, it can be set at one end or both ends of the monitoring object. For example, the alarm module can give an alarm by means of voice reminder, text display, light warning, sending a warning signal, etc. For example, when the monitoring object is abnormal, the alarm module set at one end of the monitoring object can give a warning reminder by displaying the warning text "Danger, Do Not Pass" on the display screen, or can give a warning reminder by emitting the voice "Danger, Do Not Pass" through the speaker. It can also send a warning message to vehicles and user terminals near the monitoring object, such as mobile phone devices, for warning reminder, or send a warning message to government agencies, such as the traffic bureau, the fire department, etc., for alarm.

[0034] In this embodiment, by providing a main control module, a power supply module, an alarm module, a plurality of power sockets, and detachable wires connected to the power sockets, it is possible to monitor a monitoring object and give an alarm when the monitoring object is abnormal.

[0035] In some embodiments, please refer to Figure 2 , the landslide monitoring and early warning system may further include a plurality of controllers 40 (exemplarily illustrated by two controllers 40 in the figure). Each controller 40 is disposed between adjacent power sockets 30. The controller 40 is electrically connected to the power socket 30 through a wire. Each power socket 30 is electrically connected to the power supply module 20. Each controller 40 is also communicatively connected to the main control module 10 through a communication line.

[0036] The controller 40 is disposed between adjacent power sockets 30 and is connected through a detachable wire, so as to detect the connection condition of the wire. The controller 40 is communicatively connected to the main control module through a communication line, and will send a signal including the wire connection condition to the main control module in real time. It should be understood that the power socket and the detachable wire are disposed on the monitoring object. When the monitoring object undergoes displacement or fracture, the detachable wire will be disconnected, and the controller 40 will also be disconnected and lose contact, and will not be able to send a signal to the main control module. If the main control module does not receive the signal sent by the controller within a preset time, it is known that the monitoring object is abnormal, and the position of the abnormal wire is determined through the corresponding relationship between the controller and the wire, so as to determine the position where the monitoring object is abnormal, enabling the main control module to timely master the state of the monitoring object and know which part has a problem when an abnormality occurs. In other embodiments, when the monitoring object undergoes displacement or fracture, the detachable wire is disconnected, and the controller will detect the disconnection of the wire and send a warning signal to the main control module 10, so that the main control module 10 can quickly master the abnormal state of the monitoring object and know which section of the wire is disconnected and has a problem.

[0037] In some embodiments, the monitoring object includes a bridge or a road.

[0038] Among them, the embodiments of the present application are applicable to most bridges, including bridges of various structures, such as beam bridges, arch bridges, suspension bridges, etc., bridges of various lengths, such as extra-large bridges, large bridges, medium bridges, small bridges, etc., and bridges of various material types, such as wooden bridges, steel bridges, reinforced concrete bridges, etc.

[0039] The embodiments of the present application are applicable to most roads, including highways, expressways, concrete roads, asphalt roads, sandy roads, gravel roads, etc.

[0040] In some embodiments, when the monitoring object is a bridge, the power socket and the wire are disposed on the side of the bridge. When the monitoring object is a road, the power socket and the wire are disposed on the side of the road.

[0041] When the monitoring object is a bridge, the power socket and wires are arranged on the side of the bridge. For example, when an abnormal situation occurs to the bridge, such as displacement or fracture of the bridge, the wires arranged on the side of the bridge will be pulled and disconnected, and the circuit will be disconnected accordingly. The main control module detects the disconnection of the circuit through the internal detection unit and controls the alarm module to give an alarm.

[0042] For example, when an abnormal situation occurs to the bridge, such as displacement or fracture of the bridge, the wires arranged on the side of the bridge will be pulled and disconnected. The controller of the power socket arranged on this section of the wire continuously sends signals to the main control module before the wire is disconnected. When the wire is disconnected, the corresponding circuit is disconnected, and the corresponding controller loses current and stops sending signals to the main control module. If the main control module does not receive the controller signal within the preset time, it determines that the corresponding wire is abnormal, determines the position of the abnormal wire through the corresponding relationship between the controller and the wire to determine the position where the bridge has an abnormality, and gives an alarm through the alarm module.

[0043] In some embodiments, when an abnormality occurs to the bridge and the wire is disconnected, the controller connected to the wire will detect the disconnection signal and send it to the main control module. The main control module receives the disconnection signal, determines the position of the disconnected wire to determine the position where the bridge has an abnormality, such as the position where the bridge is fractured, and gives an alarm through the alarm module.

[0044] When the monitoring object is a road, the power socket and wires are arranged on the side of the road. For example, when an abnormal situation occurs to the road, such as displacement or collapse of the road, the wires arranged on the side of the road will be pulled and disconnected, and the circuit will be disconnected accordingly. The main control module detects the disconnection of the circuit through the internal detection unit and controls the alarm module to give an alarm.

[0045] For example, when an abnormal situation occurs to the road, such as displacement or collapse of the road, the wires arranged on the side of the road will be pulled and disconnected. The controller of the power socket arranged on this section of the wire continuously sends signals to the main control module before the wire is disconnected. When the wire is disconnected, the corresponding circuit is disconnected, and the corresponding controller loses current and stops sending signals to the main control module. If the main control module does not receive the controller signal within the preset time, it determines that the corresponding wire is abnormal to determine the position where the road has an abnormality and gives an alarm through the alarm module.

[0046] In some embodiments, when an abnormality occurs to the road and the wire is disconnected, the controller connected to the wire will detect the disconnection signal and send it to the main control module. The main control module receives the disconnection signal, determines the position of the disconnected wire to determine the position where the road has an abnormality, such as the position where a collapse occurs, and gives an alarm through the alarm module.

[0047] It should be understood that this system is a physical trigger mechanism, which has the characteristics of simple structure, convenient replacement, long coverage distance and high reliability. In extreme environments, it is more stable than the monitoring system using sensors and data processing systems. When the sensors and data processing systems fail, this system can still give early warnings physically.

[0048] In some embodiments, the number of the main control module and the alarm module is one. The main control module is connected to the alarm module, and the main control module is communicatively connected to the controller through a communication line. When the monitoring object is a bridge, the main control module and the alarm module are arranged at one end of the bridge. When the monitoring object is a road, the main control module and the alarm module are arranged at one end of the road.

[0049] When only one main control module and one alarm module are used, the main control module and the alarm module are arranged at one end of the bridge or the road. For example, when an abnormal situation occurs on the bridge or the road, the main control module arranged at one end controls the alarm module to give an alarm to issue a warning reminder. For example, it can issue a voice reminder or display a warning message on a display screen to remind vehicles or personnel about to enter the bridge or the road, or send a warning message to nearby vehicles or user devices to prompt vehicles and personnel not to enter the abnormal bridge or road to avoid losses or casualties.

[0050] In some embodiments, the number of both the main control module and the alarm module is two. One alarm module is connected to one main control module, and multiple controllers are respectively communicatively connected to the two main control modules. When the monitoring object is a bridge, one main control module and one alarm module are respectively arranged at both ends of the bridge. When the monitoring object is a road, one main control module and one alarm module are respectively arranged at both ends of the road.

[0051] When two main control modules and alarm modules are used, one main control module and alarm module are arranged at one end of the bridge or the road, and the other main control module and alarm module are arranged at the other end of the bridge or the road. For example, when an abnormal situation occurs on the bridge or the road, the main control modules arranged at both ends control the alarm modules to give an alarm to prompt passing personnel or vehicles not to drive into the dangerous area or drive carefully and leave the dangerous area as soon as possible.

[0052] In some embodiments, it should be understood that there can be multiple main control modules and alarm modules, which are respectively arranged on the monitoring object to achieve longer-distance or larger-range monitoring and early warning.

[0053] In some embodiments, the alarm module includes an acoustic-optic alarm unit.

[0054] The acoustic-optical alarm unit can issue an alarm through sound, light, display, etc. For example, the acoustic-optical alarm unit can include an acoustic-optical alarm, which can simultaneously emit two alarm signals of sound and light. When an emergency occurs, it can quickly emit a high-decibel alarm sound, a strong flashing signal, and a clear voice prompt to attract people's attention and take corresponding countermeasures.

[0055] In some embodiments, the alarm module further includes a communication unit for sending broadcast signals. The communication unit is also connected to the traffic command center or the traffic monitoring system through wired communication, wireless communication, and / or satellite communication.

[0056] It should be understood that the alarm module is communicatively connected to the traffic command center or the traffic monitoring system through the communication unit. When an abnormality occurs to the monitored object, it can promptly alarm the traffic command center or the traffic monitoring system, facilitating the traffic command center or the traffic monitoring system to quickly grasp the abnormal situation. For example, in the case of bridge fracture, road collapse, etc., it can be quickly processed. For example, through the broadcast system or the navigation system, passing vehicles can be reminded to pay attention to safety.

[0057] In some embodiments, the acoustic-optical alarm unit is an LED display screen.

[0058] Specifically, warning signals can be displayed on the LED display screen in the form of text, graphics, images, animations, videos, recordings, etc. to prompt passing vehicles to pay attention to safety.

[0059] In some embodiments, the power supply module includes a solar power supply unit and / or a wind power supply unit.

[0060] Among them, the solar power supply unit can convert solar energy into electrical energy, with the characteristics of no noise, no pollution, high reliability, etc. Power supply through the solar power supply unit can reduce the requirements for the power supply environment, and it can also be used in places where it is inconvenient to use cable power transmission. Moreover, compared with battery power supply, it can be used for a long time and is more environmentally friendly and stable.

[0061] The wind power supply unit can convert the kinetic energy of the wind into electrical energy, with the characteristics of cleanliness, good environmental benefits, renewable, and inexhaustible. Power supply through the wind power supply unit can reduce air pollution and the emission of greenhouse gases, achieving clean environmental protection. Since wind is a renewable resource, electrical power can be continuously obtained, unlike traditional power supply that is affected by the power grid, and a lot of electrical energy is lost during the process of cable power transmission.

[0062] It should be understood that in actual use, the power supply module may only include a solar power supply unit or a wind power supply unit, or may include both a solar power supply unit and a wind power supply unit, or may include other power supply units at the same time, such as a mains power supply unit or a battery power supply unit, etc. By using the above power supply units, the landslide monitoring and warning system can work continuously for a long time, so as to realize long-term uninterrupted monitoring of the monitoring object, and when an abnormality occurs to the monitoring object, it can be sensed and an alarm can be issued at the fastest speed.

[0063] In some embodiments, the controller is a CAN controller, and the communication line is a CAN communication line, including a CANH communication line and a CANL communication line.

[0064] Each CAN controller is arranged between adjacent power sockets and is connected to the power socket in a pluggable manner through an electric wire. Each CAN controller is communicatively connected to the main control module through a CAN communication line, including a CANH communication line and a CANL communication line.

[0065] The data communication between each node of the control system is controlled in a reliable and real-time manner through the fieldbus CAN control method. It should be understood that each node in the embodiment of the present application may be each power socket node. Among them, the CANH communication line is the high-level data line, and the CANL communication line is the low-level data line. CANH and CANL exist in a twisted form to form a twisted pair structure for data transmission, and the transmission rate can be set according to the actual distance. In this embodiment, a two-wire CANH, CANL high-low coding ID master-slave identification communication method is adopted. Each node is provided with a CAN controller. When multiple nodes send data, arbitration is automatically performed according to the sent ID number, so that the bus data will not be confused. After a node finishes sending data, another node detects that the bus is idle and can immediately send data, eliminating the need for the host to inquire, improving the bus utilization rate, and enhancing the speed.

[0066] During implementation, each CAN controller and the main control module have independent ID numbers. In the normal working state, each CAN controller will sequentially send the ID number to the main control module. When the main control module receives the ID number, it knows that the corresponding CAN controller, the corresponding power socket, and the corresponding wire are in normal state. If each CAN controller sends the ID number normally, it means that the monitoring object is normal. When an abnormal situation occurs to the monitoring object, the pluggable wire will be disconnected, and the corresponding circuit will also be disconnected. The power socket cannot provide power to the CAN controller, and the CAN controller cannot send the ID number to the main control module. If the main control module does not receive the message sent by the CAN controller within the preset time, it is determined that the corresponding wire is abnormal. According to the corresponding relationship between the CAN controller, the power socket, and the wire, the location where the abnormal phenomenon occurs to the monitoring object is determined, and an alarm is issued through the alarm module. The abnormal location of the monitoring object can also be sent through the alarm module so that the maintenance personnel can quickly determine the abnormal location and deal with it as soon as possible.

[0067] In some embodiments, the landslide monitoring and early warning system further includes an auxiliary device, and the auxiliary device includes a wire fixing device, an insulation protection device, and a waterproof and dustproof device.

[0068] The auxiliary device can better fix the wire, prevent electric leakage, and also be waterproof and dustproof, ensuring that the wire can be used in harsh environments, improving the stability and reliability of the system, and increasing the applicable environment of the system.

[0069] In summary, the embodiments of the present application can achieve alarm when an abnormality occurs to the monitored object by setting a main control module, a power supply module for providing power, a plurality of power sockets arranged on the monitored object, a pluggable wire connected to the power socket, and an alarm module, and the system has a simple structure, low cost, and is easy to install and maintain.

[0070] It should be noted that when an element is expressed as "connected" to another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween.

[0071] It should be noted that the device embodiments described above are merely illustrative.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above.
