Description

Technical Field

[0001] This application relates to the field of intelligent monitoring technology, specifically to a remote monitoring and management system for road traffic facilities. Background Technology

[0002] China is one of the countries with the most developed road transportation in the world, one of the countries with the longest highway mileage, and one of the countries with the most mountains. Due to the complex geographical environment, there are many road transportation facilities such as tunnels and mountain roads. Also, due to the complex geographical environment, natural disasters such as earthquakes, flash floods, mudslides, and ground subsidence occur frequently, which can cause serious damage to road transportation facilities. For example, tunnel lighting and water accumulation failures, landslides, and road collapses can all threaten the safety of vehicles and people and cause great economic losses.

[0003] Existing technologies provide several monitoring systems for road traffic facilities. These systems include a monitoring center and a detection module. The detection module detects whether the road traffic facilities are intact, such as whether the road has collapsed, whether there has been a landslide, whether there is abnormal water accumulation in the tunnel, and whether the lighting in the tunnel is malfunctioning. The detection module transmits the detection data to the monitoring center, which processes the data and determines whether the road traffic facilities are malfunctioning. When the monitoring center determines that the road traffic facilities are malfunctioning, it sends a signal to the corresponding emergency response platform and alarm center to promptly arrange repairs and personnel evacuation, thereby reducing casualties and economic losses.

[0004] However, in existing monitoring systems for such road traffic facilities, the detection modules are mostly camera devices. These devices use visual detection to transmit road traffic status information wirelessly to the monitoring center. However, the over-reliance on wireless transmission for signal transmission has several drawbacks. First, road traffic facility malfunctions may affect the power supply to the camera devices, rendering them ineffective and reducing detection accuracy and monitoring timeliness. Second, extreme weather and severe geological disasters may affect the stability of wireless signal transmission, preventing timely and effective transmission of fault signals from road traffic facilities, thus hindering the monitoring center's ability to receive signals promptly and reducing monitoring timeliness. Third, the camera devices require separate power supplies and regular battery replacements and repairs, significantly increasing maintenance costs.

[0005] Therefore, the existing monitoring and management systems for traffic road facilities have room for further improvement. Summary of the Invention

[0006] In view of the above-mentioned technical problems of the existing remote monitoring and management system for road traffic facilities, which uses camera devices for detection and wireless transmission of signals between the camera devices and the monitoring center, resulting in high maintenance costs, easily interfered and unstable signals, and poor monitoring timeliness, this application provides a remote monitoring and management system for road traffic facilities, including signal lines and power lines. Sub-nodes and monitoring nodes are connected via power lines, allowing the detection module and monitoring node to share a power supply, eliminating the need for additional dry-cell batteries for the detection module, reducing maintenance costs and environmental pollution. Furthermore, the detection module does not require an additional wireless communication module, thus eliminating the need to set a communication address, further reducing costs. Sub-nodes and monitoring nodes are connected via signal lines, while the detection module and monitoring node transmit data via wired means. When a road traffic facility malfunctions, if the detection module breaks or is damaged, it will transmit an electrical signal to the monitoring node via the signal line, enabling the monitoring node to receive the road traffic facility malfunction signal in a timely and accurate manner. The signal transmission is relatively stable, allowing the monitoring node to promptly transmit road condition information to the relevant platform, reducing the harm of road traffic facility malfunctions to pedestrians, vehicles, and residents.

[0007] This application provides a remote monitoring and management system for road traffic facilities, comprising: Sub-nodes include detection modules for detecting the status information of traffic and road facilities; An alarm device, used to issue alarm information, including a speaker; The monitoring node is connected to the detection module and alarm device, and is used to automatically control the alarm device to start and stop based on the received status information of traffic and road facilities.

[0008] Compared with existing technologies, the remote monitoring and management system for road traffic facilities provided in this application can promptly issue alarms through alarm devices when road traffic facilities malfunction. These alarm devices include speakers, thus providing audible warnings to alert residents, vehicles, and pedestrians near the accident site, reducing casualties and economic losses. Connecting the sub-nodes and alarm devices to the monitoring node via power lines allows the detection module, alarm device, and monitoring node to share a power supply, eliminating the need for additional dry-cell batteries and reducing maintenance costs and environmental pollution. Furthermore, connecting the sub-nodes and alarm devices to the monitoring node via signal lines eliminates the need for additional wireless communication modules, thus eliminating the need for communication setup. The system addresses the issue of reduced costs; and the wired transmission between the detection module, alarm device, and monitoring node ensures stable signal transmission, enabling the monitoring node to promptly transmit road condition information to the relevant platform, thus reducing the harm to pedestrians, vehicles, and residents caused by road traffic facility malfunctions. The monitoring node can receive detection information from sub-nodes promptly and stably, process and judge the information, and transmit alarm information to the alarm device via signal lines, ensuring a fast and stable response from the alarm device. This enhances the effectiveness and stability of the monitoring management system. Furthermore, the grounding connection between the sub-nodes, alarm devices, and monitoring node via grounding wires ensures the normal operation of the sub-nodes and monitoring node and provides interference protection.

[0020] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0021] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0022] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0023] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 21 illustrate.

[0024] This application provides a remote monitoring and management system for road traffic facilities (hereinafter referred to as the monitoring and management system), which is used to remotely monitor and manage facilities related to traffic roads such as bridges, roadbeds, tunnels, and mountains. It can automatically and promptly issue alarm information to remind residents, vehicles, and pedestrians in the accident area to quickly move away from the accident site, thereby reducing the life hazards and economic losses caused by road traffic facility failures.

[0025] like Figures 1 to 2 As shown, the monitoring and management system of this application includes a sub-node 2, a YH.JK3C transmission layer, a monitoring node 1, and an application layer 8. The sub-node 2 is the physical layer, which includes a detection module for detecting or sensing the status of traffic road facilities and an execution control module for controlling the corresponding traffic road facilities. The sub-node 2 is connected to the monitoring node 1 through the YH.JK3C transmission layer, and the monitoring node 1 is connected to the application layer 8 through a wireless network. The sub-node 2 can transmit the detected status information of the road traffic facilities to the monitoring node 1 through the YH.JK3C transmission layer. The monitoring node 1 will promptly issue an alarm and transmit the status information of the road traffic facilities to the application layer 8, promptly notify the rescue platform, etc., for timely rescue and repair, and issue alarm information at the location of the road traffic facility to remind residents, vehicles, and pedestrians in the accident area to quickly move away from the accident area, thereby reducing the harm of road traffic facility failure to pedestrians, vehicles, and residents.

[0026] When sub-node 2 includes both a detection module and an execution control module, it can simultaneously achieve remote monitoring and remote management, thereby improving the practicality of the monitoring and management system.

[0027] In this application, monitoring node 1 includes a processor and an alarm device 6. The alarm device 6 and the detection module are both connected to the processor through the YH.JK3C transmission layer. The YH.JK3C transmission layer includes a row of sockets 3, which is made using YH.JK3C technology. The row of sockets 3 has multiple I / O ports, a common negative port, and a power interface. The power line is connected to the power interface, the signal line is connected to the I / O signal port, and the grounding line is connected to the common negative port, so that the row of sockets 3 has the characteristics of YH.JK3C technology. The YH.JK3C technology can be referred to the relevant content described in the invention with application number CN200910101912.7. It can be seen that YH.JK3C technology is a simple combination of three wires: one is a signal line used to transmit switch or analog information; the other two are a grounding line and a power line, which together enable monitoring node 1 to provide power to the physical layer. Therefore, YH.JK3C technology fundamentally overcomes the shortcomings of wireless LAN radio frequency signals, such as signal weakening or even interruption when the signal is in an indoor space exceeding 30m, and susceptibility to co-channel interference. The YH.JK3C transmission layer can ensure stable signal transmission.

[0028] Therefore, in this embodiment, as Figure 6 , Figure 10 As shown, monitoring node 1 also includes a power adapter, which is connected to a DA220V power supply and converts it to DC 9~30V to power the processor. Alarm device 6 is connected to the processor via a power strip 3. The processor contains a CPU, an I / O expansion module, and an audio amplification module. The power strip 3 connects to the I / O expansion module, and the audio amplification module connects to the CPU. The CPU converts alarm information into audio information, which is then transmitted to the audio amplification module, which connects to alarm device 6. Alarm device 6 includes a speaker, which broadcasts the alarm information via sound to alert vehicles, pedestrians, and residents in the accident area to take evasive action. Alarm device 6 shares power with the processor via the power strip 3, eliminating the need for an additional power supply. Furthermore, the alarm device 6 and processor transmit signals via a YH.JK3C signal cable, ensuring stable signal transmission and enabling stable and timely automatic alarms.

[0029] In this application, as Figures 1 to 5 As shown, application layer 8 includes a monitoring center and a mobile terminal. The processor of monitoring node 1 is equipped with a wireless communication module, enabling signal transmission between the monitoring center and monitoring node 1 via the GSM wireless transmission layer; as shown... Figure 6 As shown, the wireless communication module includes a radio frequency transceiver module, a satellite signal transceiver module, and a GPRS mobile communication module; as Figure 7As shown, the monitoring center includes a processor, video processing module, display screen, central processing system, conversion module, radio frequency module, and GPRS / GSM mobile module. This enables the monitoring center to decode the code information of monitoring node 1, converting it into perceived traffic and road status information. For specific connection methods and other structural details, please refer to [reference needed]. Figure 7 As shown, most of the technology here is existing and will not be elaborated on further.

[0030] Among them, mobile terminals include any one or more mobile terminals such as engineering rescue platforms, road administration administrators' mobile phones or tablets, handheld systems, mobile phones or tablets at accident sites, and vehicle-mounted systems at accident sites, thereby enabling the monitoring center to transmit information to application layer 8 wirelessly; correspondingly, such as Figure 1 , Figure 2 , Figure 5 As shown, monitoring node 1 encodes the electrical signal information transmitted by the YH.JK3C transport layer into code information and transmits it to the monitoring center or mobile terminal. The code information simplifies the communication bytes and content; the content sent by monitoring node 1 consists only of a code for monitoring node 1 itself and a single character in the byte sequence, such as an Arabic numeral or an English letter. All the message content resides in the monitoring center and mobile terminal, making it impossible to decipher the specific content even if the information from monitoring node 1 is intercepted. The monitoring center and mobile terminal can receive and decode the code information from monitoring node 1, converting it into perceived traffic and road status information.

[0031] The perception aspect includes any one of visualization, hearing, touch, and smell to enhance alerting capabilities, thereby providing timely, rapid, and efficient notifications to users and reducing the safety hazards posed by road traffic facility malfunctions. For example, vehicles or pedestrians approaching an abnormal road section can automatically receive traffic status information sent by the monitoring center or monitoring node 1, allowing them to avoid danger in a timely manner. In this embodiment, the alarm device 6 includes not only a speaker but may also include a display screen or light alarm to achieve audible and visual alarms, such as voice or text messages like "Abnormality at ×× line ×× road, suspected collapse, vehicles and pedestrians prohibited from passing, quickly move away."

[0032] In the remote monitoring and management system for traffic and road facilities of this application, such as Figure 5 As shown, in the monitoring and management system, the detection module transmits data to monitoring node 1 through the YH.JK3C transport layer. Monitoring node 1 then transmits the information to the monitoring center or mobile terminals such as mobile phones via the public mobile network, thus completing the entire process of information monitoring and feedback. Similarly, as... Figure 4As shown, the monitoring center and mobile terminal of this application can receive the status information of monitoring node 1 and also transmit control signals to monitoring node 1 to control the controlled facility and complete specific instructions. Among these, Figure 5 This is a flowchart of the control command signal transmission of the remote monitoring and management system for traffic road facilities of this application. When the mobile communication network in the monitoring and management system of this application fails, the system can seamlessly connect by entering its own username and relevant password in the user login column of the monitoring node 1 platform and remotely operate with the mouse, thereby realizing alarm processing at the location of the traffic accident.

[0033] Based on any of the above embodiments, the monitoring and management system of this application is further extended; in this application, the monitoring and management system also includes a linkage controller 5, the principle structure of which is as follows: Figures 11 to 13 The diagrams shown are the structural schematics of a single-element linkage controller 5, a two-element linkage control structure, and a three-element linkage control structure, respectively. (See attached diagrams.) Figure 13 As shown, K1, K2, and K3 correspond to three relay controllers 51, which operate on the principle of relays 41. The outputs of the three relay controllers 51 are connected in series, and their inputs are connected in parallel. Each relay controller 51's input can be connected to a different signal module. When all three signal modules respond and transmit the corresponding level signal to the three relay controllers 51, all three relay controllers 51 are connected, thus enabling the linkage controller 5 circuit to conduct. In this embodiment, the specific principle of the linkage controller 5 is existing technology; for details, please refer to Chinese Patent Application No. 2009101019127, which will not be elaborated upon here. The output of the linkage controller 5 is connected in series to the signal input of the alarm device 6, and the input of the relay controller 51 is connected to the detection module, such as... Figure 11 As shown, when the detection module sends a detection signal, the linkage controller 5 is turned on and the alarm device 6 sounds an alarm. By setting the linkage controller 5, the probability of false alarms from the alarm device 6 can be reduced.

[0034] If the linkage controller 5 includes only one relay controller 51, the output terminal of the linkage controller 5 is connected in series with the signal input terminal of the alarm device 6, and the input terminal of the relay controller 51 is connected to the detection module, wherein, for example... Figure 10As shown, the detection module is connected to one of the I / O ports of the row socket 3. The detection module sends a signal, which is split into two paths. One path goes directly into the processor of the monitoring node 1 through the row socket 3 and is processed by the monitoring node 1. The other path is a level signal that goes through the input terminal of the linkage controller 5 connected in series to another I / O port on the row socket 3. This level signal causes the electromagnetic coil of the relay controller 51 in the linkage controller 5 to be energized, which attracts the armature and connects the external AC220V power supply to the electrical contacts on the armature. The alarm device 6 then responds immediately, thereby realizing hardware linkage control.

[0035] Through such coordinated control, the response of the alarm device 6 is bound to the detection of the detection module, enabling rapid alarm. It should be noted that in this embodiment, the linkage controller 5 is connected to the row socket 3, and the row socket 3 can supply power to the linkage controller 5. In addition, the processor can send signals to the linkage controller 5 through the row socket 3 to control whether the linkage controller 5 is in operation.

[0036] Furthermore, if the linkage controller 5 only includes two relay controllers 51, such as Figure 12 As shown, the input terminals of the two relay controllers 51K1 and K2 are connected in parallel, and the output terminals of each relay controller 51 are connected in series. One input terminal of the two relay controllers 51 is connected to the row socket 3, and the other input terminal is connected to the detection module. This requires the alarm device 6 to respond to both the alarm signal from the processor and the trigger signal from the detection module. The alarm signal from the processor and the trigger signal from the detection module corroborate each other, reducing the probability of false alarms and improving the accuracy of the alarm.

[0037] Based on the above embodiments, the monitoring and management system of this application further includes auxiliary detection sensors such as visual inspection devices, etc. Figure 6 As shown, the processor includes a video module, which is connected to a vision inspection device. The video module analyzes and processes images of the road traffic facilities obtained by the vision inspection device to determine the status of the road traffic facilities, so that the application layer 8 can flexibly view the status of the road traffic facilities through the vision inspection device, which facilitates flexible monitoring.

[0038] In this embodiment, the visual inspection device is a camera device 23.

[0039] One of the input terminals of the linkage controller 5 is connected to the detection module, and the other input terminal is connected to the video module. When the video module processes the acquired image and generates signals such as road traffic facility malfunctions, it can send a level signal to the linkage controller 5. Under the dual detection and verification of the detection module and the visual detection device, the probability of false alarms can be further reduced.

[0040] In this application, as Figure 8 , Figure 9 As shown, the information is confirmed before being transmitted from the monitoring center to the mobile terminal; Figure 8 This is a schematic diagram illustrating how unconfirmed information transmissions are judged as erroneous and will not be sent to emergency response centers or other rescue platforms. Figure 9 The principle behind sending verified information to emergency response platforms such as the dispatch center is as follows: Figure 9 In this system, when data collector a detects an alarm, to prevent false alarms, detector b is used for confirmation, or detectors c and d are used for further confirmation. If b, c, and d all trigger alarms simultaneously when or after a triggers an alarm, then the alarm is confirmed. Sensors can verify the same information between similar sensors, between different types of sensors, or between different types of sensors. In this embodiment, multi-level confirmation, similar-type confirmation, and same-type confirmation are used to verify the authenticity of the information, ensuring the reliability of the alarm and thus improving the reliability of the monitoring and management system of this application.

[0041] In this application, the distance between each monitoring node 1 is approximately 1 to 2 kilometers to ensure that the monitoring nodes 1 can communicate with each other and transmit the alarm information of adjacent monitoring nodes 1, so as to ensure alarm coverage of dangerous areas.

[0042] like Figure 3 , Figure 10 As shown, the remote monitoring and management system for road traffic facilities provided in this application includes any one or more of the following: tunnel lighting monitoring and management system, tunnel water accumulation monitoring and management system, tunnel collapse monitoring and management system, bridge fracture monitoring and management system, road collapse monitoring and management system, landslide monitoring and management system, debris flow monitoring and management system, and earthquake monitoring and management system. It can also simultaneously realize the monitoring and management of all the above-mentioned road traffic facilities. Specifically, the appropriate number and applicable functions of the monitoring and management system can be selected according to the environment in which the traffic facilities are located.

[0043] In an optional embodiment of this application, a tunnel lighting monitoring and management system is described in detail; such as Figure 14 , Figure 15As shown, the detection module includes a first brightness detection sensor and a second brightness detection sensor. The first brightness detection sensor is located outside the tunnel to detect the brightness outside the tunnel; the second brightness detection sensor is located inside the tunnel to detect the brightness inside the tunnel. At least two sets of lights 7 are installed inside the tunnel. An execution controller 4 is connected between the light sets 7 and the monitoring node 1. The execution controller 4 controls the opening and closing of the light sets 7 and is an execution control module. The monitoring node 1 is connected to the first brightness detection sensor, the second brightness detection sensor, and the execution controller 4 via the YH.JK3C transmission layer. That is, the first brightness detection sensor, the second brightness detection sensor, the execution controller 4, and the monitoring node 1 share a power supply. The monitoring node 1 receives the brightness values ​​detected by the first and second brightness detection sensors outside and inside the tunnel, respectively, and sends corresponding signals to the execution controller 4 based on the brightness comparison information inside and outside the tunnel to increase or decrease the number of lights 7 that are turned on. This achieves automatic adjustment of the tunnel lighting brightness based on the brightness information inside and outside the tunnel, reducing the brightness difference between inside and outside the tunnel to avoid excessive brightness differences and thus reducing the probability of traffic accidents caused by the brightness difference between inside and outside the tunnel.

[0044] In this application, there are at least two sets of lights 7 in the tunnel, and each set of lights 7 includes multiple lights connected in parallel. The brightness change in the tunnel is adjusted by changing the number of lights 7 lit in the tunnel.

[0045] In this embodiment, as Figure 6 As shown, the processor includes a light control module, which includes a processing module and a brightness sensor. The light control module is connected to N brightness sensors through I / O ports. The brightness sensors transmit the detected real-time data to the processor in a timely manner. After the processor compares the two sets of data, it transmits the compared data back to the light control module. The light control module determines whether to increase or decrease the brightness of the tunnel lights based on the processor's data, and sends the result to the execution controller group 4 through the I / O expansion module to control the number of lighting groups 7.

[0046] Among them, such as Figure 14 , Figure 15 As shown, there are two groups of lights 7, which are independently controlled. There are two actuator controllers 4, each connected to one group of lights 7, and each actuator controller 4 independently controls the opening and closing of one group of lights 7. Multiple actuator controllers 4 are integrated to form an actuator controller group 4. Figure 14 As shown, the actuator controller 4 group is provided with a socket for connecting to the lamp group 7 to form a lamp group 7 row socket 3.

[0047] Furthermore, the execution controller 4 will be described in detail; such as Figure 15As shown, the execution controller 4 includes a relay 41, an air switch 43, an adapter, and a power socket. The relay 41 includes normally closed contacts and normally open contacts. The input terminal (first contact) of the normally closed contact is connected to the output terminal of the I / O expansion module of the monitoring node 1. The input terminal of the air switch 43 is connected to the AC220V power supply. The output terminal of the air switch 43 is connected to the input terminal (third contact) of the normally open contact of the relay 41. The output terminal (fourth contact) of the normally open contact is connected to the input terminal of the power socket. The lamp group 7 is connected to the power socket. The adapter is used to convert the AC220V voltage into a DC 9~12V voltage to power the relay 41. The output terminal of the adapter is connected to the output terminal (second contact) of the normally closed contact of the relay 41. A resistor is connected in parallel below the normally closed contact of the relay 41 and a light-emitting diode is connected in series to form a circuit. The principle of the adapter powering the relay 41 is existing technology and will not be described in detail here.

[0048] In this embodiment, the processor's I / O expansion module is connected to the input terminal of the normally closed contact, and is used to input a high-level signal or a low-level signal to the input terminal (the first contact) of the normally closed contact to realize the opening and closing of the relay 41, thereby controlling whether the lamp group 7 is turned on or off; for example Figure 15 As shown, the system includes two groups of lights, A and B, 7, and two sets of execution controllers 4, A and B. Execution controller 4 of group B controls group light 7 to be on, while execution controller 4 of group A controls group light 7 to be off. The process of turning on group light 7 is as follows: When execution controller 4 of group B receives a high-level execution command from monitoring node 1, the coil of relay 41 is energized, generating a magnetic field that attracts the armature of relay 41. The electrical contacts on the armature energize the power socket below. Simultaneously, the armature on relay 41 is not locked, meaning the normally open contact of relay 41 is closed. At this time, group light 7 is on and illuminated. To turn off group light 7, a low-level signal must be sent to the I / O port (first contact) of execution controller 4. At this time, the normally open contact of relay 41 of execution controller 4 of group B opens, the armature of relay 41 returns to the open state, and group light 7 is off.

[0049] Among them, such as Figure 15 As shown, the execution controller 4 also includes a first indicator light 44 and a second indicator light 45. The first indicator light 44 illuminates a first color when the light group 7 is off, and the second indicator light 45 illuminates a second color when the light group 7 is on. The first color is red, and the second color is green, to achieve a clear indication effect. The connection structure of the first indicator light 44 and the second indicator light 45 is shown in [reference needed]. Figure 15 This will not be elaborated upon here.

[0050] like Figure 15As shown, the controller 4 can also be equipped with a remote control switch 42. The remote control switch 42 is a single-pole double-throw switch. By setting the remote control switch 42, the on / off status of the lamp group 7 can be remotely controlled, improving the flexibility of use. Figure 15 As shown in groups A and B 7, in group B, when the remote control switch 42 is connected to the first interface, the execution controller 4 of group B is connected, group B lights up, the circuit of the second indicator light 45 is turned on, and the second indicator light 45 lights up green; in group A, when the remote control switch 42 is connected to the second interface, the execution controller 4 of group A is connected, group A lights up, the circuit of the first indicator light 44 is turned on, and the second indicator light 45 lights up red.

[0051] Specifically, the output of the linkage controller 5 can be connected in series with the signal input of the execution controller 4. When the output of the linkage controller 5 is connected in series with the signal input of the execution controller 4, the execution controller 4 can only receive the level signal transmitted by the monitoring node 1 when the linkage controller 5 is turned on, and thus control the switching state of the lamp group 7, thereby achieving control over the lighting brightness inside the tunnel. Specifically, for example... Figure 12 As shown, the linkage controller 5 includes two relay controllers 51. The input terminal of each relay controller 51 is connected to the output terminal of a first brightness detection sensor. That is, only when the first brightness detection sensor is not damaged and can normally respond to transmit the detection signal to the monitoring node 1, will the relay controller 51 be energized, thus turning on the linkage controller 5. Through this mutual verification method, it is ensured that the light-sensitive detection function outside the tunnel is normal before the brightness of the lighting inside the tunnel can be adjusted. This indicates that the sub-node 2 set outside the tunnel in the tunnel lighting monitoring and management system is good, thereby reducing the probability of false detection and ensuring the accuracy of the adjustment of the tunnel lighting brightness. The probability of brightness adjustment error inside the tunnel is reduced.

[0052] Preferably, the input terminals of the two relay controllers 51 of the linkage controller 5 can also be connected to the two second brightness detection sensors respectively. By verifying each other in this way, it can be ensured that the light-sensitive detection function in the tunnel is normal before the lighting brightness in the tunnel can be adjusted. This indicates that the sub-node 2 set in the tunnel in the tunnel lighting monitoring and management system is good, thereby reducing the probability of false detection and ensuring the accuracy of the tunnel lighting brightness adjustment. The probability of brightness adjustment error in the tunnel is reduced.

[0053] Preferably, the input terminals of the two relay controllers 51 of the linkage controller 5 can also be connected to a first brightness detection sensor and a second brightness detection sensor respectively. By verifying each other in this way, the light-sensitive detection function inside and outside the tunnel is guaranteed to be normal before the brightness of the tunnel lighting can be adjusted. This indicates that the sub-node 2 set in the tunnel in the tunnel lighting monitoring and management system is good, thereby reducing the probability of false detection and ensuring the accuracy of the tunnel lighting brightness adjustment. The probability of brightness adjustment error in the tunnel is reduced.

[0054] In an optional embodiment of this application, a tunnel water accumulation monitoring and management system is described in detail; such as Figure 10 As shown, the detection module includes a liquid level sensor 21, and sub-node 2 also includes a water pump. Both the liquid level sensor 21 and the water pump are located inside the tunnel. The liquid level sensor 21 is used to detect water accumulation information inside the tunnel, and the water pump is used to pump out the water from the tunnel. The liquid level sensor 21 is located on the ground inside the tunnel. When there is water accumulation on the tunnel ground, the liquid level sensor 21 can detect it in time and feed the water accumulation information back to monitoring node 1. After receiving the water level information, monitoring node 1 compares it with the set value. When the water accumulation in the tunnel meets the set value for pumping start, monitoring node 1 controls the water pump to run, thereby draining the water from the tunnel. When the water accumulation received by monitoring node 1 does not meet the set value, it stops the running water pump or keeps the water pump in a stopped state, thereby realizing real-time monitoring and management of water accumulation in the tunnel, so that water accumulation in the tunnel can be dealt with in a timely manner, thereby reducing the probability of traffic accidents caused by water accumulation in the tunnel not being cleaned up in time.

[0055] In this application, multiple liquid level detection sensors 21 can be configured, distributed in areas within the tunnel prone to water accumulation, without affecting vehicle traffic within the tunnel. The liquid level detection sensors 21 can be float sensors, capacitive sensors, etc., as long as they can detect water accumulation information; no restrictions are placed here. Multiple water pumps can be configured, preferably located near the liquid level detection sensors 21, to accurately pump out the accumulated water.

[0056] The output of the linkage controller 5 can be connected in series with the signal input of the water pump. When the linkage controller 5 includes a relay controller 51, the input of the relay controller 51 is connected to the liquid level detection sensor 21. This means that the linkage controller 5 needs to receive a level signal from the liquid level detection sensor 21 to indicate that the liquid level detection sensor 21 is not damaged and the processor determines that the water pump needs to be started before the linkage controller 5 will be turned on and the water pump will actually be triggered. This can reduce the probability of false triggering and ensure the accuracy of water accumulation control in the tunnel.

[0057] Of course, when the linkage controller 5 includes at least two relay controllers 51, the input terminal of at least one relay controller 51 is connected to the liquid level sensor, and the input terminals of the other relay controllers 51 can be connected to the output terminals of the video module or other auxiliary detection sensors. The water pump will only start when all the sensors that can detect water accumulation respond, which can reduce the probability of the water pump starting erroneously and improve the pumping accuracy.

[0058] In an optional embodiment of this application, a bridge fracture monitoring and management system is described in detail; such as... Figures 16 to 19 As shown, the detection module includes a linear sensor 22, which is pre-embedded 2-5 cm above the bottom surface of the bridge, specifically 2-5 cm below the surface of the concrete at the bottom of the bridge. Alternatively, linear sensors 22 can be installed simultaneously on the top or bottom surfaces of the bridge to improve detection accuracy. During pre-embedding, both ends of the linear sensor 22 need to be exposed within the inner hole of the beam to facilitate the installation of lead wire connectors. The linear sensor 22 connects to the I / O port and common negative port of the row socket 3 via the lead wire connectors, thus forming a circuit. When the linear sensor 22 breaks or is damaged, its voltage changes, transmitting a voltage signal to monitoring node 1. Monitoring node 1 then determines the bridge is broken based on this signal and automatically triggers an alarm. This detection structure using the linear sensor 22 is cost-effective, reducing construction costs. Furthermore, its detection principle is simple, direct, and rapid, resulting in accurate and reliable detection results.

[0059] In this application, the linear sensor 22 can be a metal wire or an optical fiber. Figure 16 , Figure 17 As shown, when the linear sensor 22 is a metal wire, the voltage change generated when the metal wire breaks is used to determine whether the bridge has collapsed or broken; if the linear sensor 22 is an optical fiber, the bridge has collapsed or broken is determined by the on / off state of the light.

[0060] In this application, as Figure 18 , Figure 19 As shown, the linear sensors 22 are installed on both sides of the bridge in the width direction. The linear sensors 22 are arranged in a U-shape, and the length of each linear sensor 22 is 500 to 1500 meters.

[0061] If the linkage controller 5 includes only one relay controller 51, the output terminal of the linkage controller 5 is connected in series with the signal input terminal of the alarm device 6, and the input terminal of the relay controller 51 is connected to the linear sensor 22, wherein... Figure 10As shown, the linear sensor 22 is connected to one of the I / O ports of the row socket 3. When the linear sensor 22 breaks, it emits an electrical signal. This signal is split into two paths: one path goes directly into the processor of the monitoring node 1 through the row socket 3 and is processed by the monitoring node 1; the other path goes through the input terminal of the linkage controller 5 connected in series to another I / O port on the row socket 3. This signal causes the electromagnetic coil of the relay controller 51 in the linkage controller 5 to be energized, which attracts the armature and connects the external AC220V power supply to the electrical contacts on the armature. The alarm device 6 then responds immediately, thereby realizing hardware linkage control.

[0062] Through such coordinated control, the response of the alarm device 6 is linked to the detection of the linear sensor 22, enabling rapid alarm. It should be noted that in this embodiment, the linkage controller 5 is connected to the row socket 3, which can supply power to the linkage controller 5. In addition, the processor can send signals to the linkage controller 5 through the row socket 3 to control whether the linkage controller 5 is in operation.

[0063] In this application, the detection module may further include a camera device 23 or a pressure sensor; the processor includes a video module connected to the camera device 23, the video module analyzes and processes the images of the bridge's state obtained by the camera device 23, thereby determining the bridge's state, so that the application layer 8 can flexibly view the bridge's state through the camera device 23, facilitating flexible monitoring; the pressure sensor is embedded in the bridge or installed on the bridge support, and continuously captures changes in stress and strain inside the bridge to determine the degree or location of damage to the bridge, thereby determining the bridge's condition.

[0064] Therefore, if the linkage controller 5 includes at least two relay controllers 51, the input terminal of at least one relay controller 51 is connected to the linear sensor 22, and the input terminals of the other relay controllers 51 can be connected to the output terminals of the video module and the pressure detection sensor. The alarm device 6 will only be activated when all the sensors that can detect the bridge fracture respond, which can reduce the probability of the alarm device 6 being activated falsely and improve the accuracy of the alarm.

[0065] In an optional embodiment of this application, the road collapse monitoring and management system is described in detail; such as Figure 20 As shown, the detection module includes a linear sensor 22. In this embodiment, the linear sensor 22 monitors and manages road collapses in the same way as the bridge fracture monitoring and management system described above. The difference lies in the placement of the linear sensor 22. In this embodiment, the linear sensor 22 is pre-embedded 2-5 cm below the road surface, and as shown... Figure 20 As shown, the linear sensor 22 adopts an S-shaped laying method to comprehensively detect the entire surface of the road.

[0066] The remaining setup structure and principles are the same as those of the bridge fracture monitoring and management system, and will not be elaborated here.

[0067] It should be noted that the detection module in the earthquake monitoring and management system also includes a linear sensor 22. Its principle is the same as that of the road collapse monitoring and management system mentioned above. The difference is that the pre-embedding depth of the linear sensor 22 is different. Based on the actual survey, in earthquake-prone areas, the pre-embedding depth of the linear sensor 22 can be reasonably set to quickly and timely detect earthquake occurrences.

[0068] In an optional embodiment of this application, a landslide monitoring and management system is described in detail; such as... Figure 21 As shown, the detection module includes a linear sensor 22, which is arranged around the perimeter of the mountain to detect its condition. The alarm device 6 is used to issue an alarm message in the event of a landslide, alerting residents, vehicles, and pedestrians in the affected area to quickly move away from the accident site. In this application, as... Figure 21 As shown, each mountain with a monitoring and management system shall have no fewer than three linear sensors 22 installed. As shown in a, b, and c, the three linear sensors 22 shall be spaced apart along the height of the mountain and shall be close to the outer surface of the mountain to ensure accurate detection. The number and spacing of the linear sensors 22 installed on each mountain can be flexibly set according to the geological structure and environment of the mountain. The laying length of each linear sensor 22 is 500 to 1500 meters, and the specific length can be selected according to actual needs.

[0069] The linear sensor 22 can be a metal wire or an optical fiber. Figure 16 , Figure 17 As shown, when the linear sensor 22 is a metal wire, the voltage change generated when the metal wire breaks is used to determine whether a landslide has occurred; if the linear sensor 22 is an optical fiber, the on / off state of the light is used to determine whether a landslide has occurred.

[0070] It should be noted that the detection principle and alarm principle of the linear sensor 22 in this embodiment are the same as those of the road collapse monitoring and management system mentioned above, and will not be repeated here.

[0071] The landslide monitoring and management system in this embodiment can also be used to monitor and manage debris flows. The two systems operate on the same principle and will not be described in detail here.

[0072] In addition, the tunnel collapse monitoring and management system of this application can also realize the monitoring and management of tunnel collapse by pre-embedding the linear sensor 22 in the top of the tunnel. Its detection and alarm principle is the same as that of the road collapse monitoring and management system mentioned above, and will not be repeated here.

[0073] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0074] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
