Description

Technical Field

[0001] The present invention relates to the technical field of tunnel monitoring, and specifically to an intelligent park control system. Background Art

[0002] With the continuous development of engineering construction technology and mining technology, various mountain tunnels, submarine tunnels, river-bottom tunnels, coal mine tunnels, etc. have emerged. The tunneling of tunnels has certain risks, and collapse accidents are likely to occur in some places where faults are prone to occur and the support is insufficient, causing personal injuries. Therefore, it is necessary to give early warnings of tunnel collapses.

[0003] Existing tunnel collapse early warning devices use laser instruments fixed on the side walls of the tunnel. The initial reflection points are obtained by the laser instruments reflecting the reflectors on the other side walls, and the displacement of the tunnel inner wall is understood by measuring the position change of the reflection points. Although this solution can detect the rock formation displacement at the tunnel inner wall, since the optical instruments are placed outside and are vulnerable to environmental interference, and there are also many interferences between the optical instruments and the reflectors, such as construction dust in the tunnel, this will lead to measurement errors and affect the measurement results, thus making the device unable to give early warnings in time. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an intelligent park control system to solve the problem that the existing tunnel collapse early warning devices use optical instruments for monitoring, but the optical instruments are vulnerable to environmental interference during use, such as construction dust in the tunnel, resulting in measurement errors and affecting the measurement results, thus making the device unable to give early warnings in time.

[0005] The present invention is realized through the following technical solutions:

[0006] An intelligent park control system includes the following steps: S1. Fix pipes and pressure sensors on the inner wall of the tunnel through a mounting rack;

[0007] S2. Electrically connect each pressure sensor to a terminal through a cable, so that multiple pressure sensors form a grid-like structure;

[0008] S3. Monitor the water pressure received by the pressure sensors, transmit the monitoring data back to the terminal, and compare it with the initial data during installation. If the monitoring data does not match the initial data, it indicates that the inner wall of the tunnel has settled;

[0009] S4. The internal water pressure of the pipes pushed out by the tunnel settlement will increase, while the internal water pressure of the adjacent pipes not pushed out by the tunnel will relatively decrease. Therefore, for the monitoring data transmitted back to the terminal by the pressure sensors, by comparing the monitoring data with the initial data, the part where the monitoring data is greater than the initial data indicates the settlement area, and the part where the monitoring data is less than the initial data indicates the edge of the settlement area;

[0010] S5. The terminal locks the settlement area, drives the displacement unit to move the camera to the vicinity of the settlement area, and transmits the content captured by the camera to the alarm center through the wireless module and alarms, facilitating remote observation of the settlement situation and discussing repair or evacuation plans;

[0011] S6. The terminal divides the settlement levels according to the difference between the monitoring data and the initial data, and transmits different display signals to the display unit according to the settlement levels, so that the display unit displays different contents.

[0012] Further defined, in S1, a plurality of pipelines are arranged uniformly along the circumferential direction of the tunnel, and each pipeline extends along the length direction of the tunnel. Then, each pipeline is fixed by an installation frame, and a plurality of pressure sensors are uniformly installed on each pipeline along the length direction of the pipeline.

[0013] Further defined, in S1, after installing the pipeline and the pressure sensor, the pipeline is filled with water, and then the water pressure in the pipeline is monitored by the pressure sensor, and the initial value is extracted as the initial data.

[0014] Further defined, in S2, a grid-like structure is formed by a plurality of pressure sensors, and the terminal can form corresponding coordinate positions according to the plurality of pressure sensors in the grid-like structure.

[0015] Further defined, in S3, the pressure sensors are monitored by the terminal, and the monitoring data is compared with the initial data. If the monitoring data is consistent with the initial data, it indicates that the tunnel has not settled and caused compression to the pipe body. If there is a difference between the monitoring data and the initial data, it indicates that the inner wall of the tunnel has settled.

[0016] Further defined, in S5, a guiding rod for the displacement unit to slide is installed in the pipeline, the camera is installed on the displacement unit, and the shooting direction faces the pressure sensor.

[0017] Further defined, in S5, the camera is electrically connected to the terminal and the wireless module, and the content captured by the camera is transmitted to the alarm center through the wireless module.

[0018] Further defined, in S6, after the inner wall of the tunnel has settled, the monitoring data is compared with the initial data to form a difference, and the settlement levels are divided according to the size of the difference. The terminal transmits different display signals to the display unit according to the settlement levels, prompting different display units to display different speed limit levels or no entry.

[0019] Further defined, in S5, the displacement unit includes a housing and rollers that are slidably engaged with the guiding rod and the guiding rod, and the rollers are in contact with the wall or floor of the tunnel;

[0036] Please refer to Figures 1-4 , the present invention provides a technical solution: a smart park management and control system, including the following steps: S1. Fix the pipeline 3 and the pressure sensor on the inner wall of the tunnel 1 through the mounting frame 2;

[0037] S2. Electrically connect each pressure sensor to the terminal through a cable, so that multiple pressure sensors form a grid-like structure;

[0038] S3. Monitor the water pressure received by the pressure sensor, transmit the monitoring data back to the terminal, and compare it with the initial data during installation. If the monitoring data does not match the initial data, it indicates that the inner wall of the tunnel 1 has settled;

[0039] S4. The internal water pressure of the pipeline 3 pushed out by the tunnel settlement will increase, while the internal water pressure of the adjacent pipelines 3 not pushed out by the tunnel will relatively decrease. Therefore, for the monitoring data transmitted back to the terminal by the pressure sensor, by comparing the monitoring data with the initial data, the part where the monitoring data is greater than the initial data indicates the settlement area, and the part where the monitoring data is less than the initial data indicates the edge of the settlement area;

[0040] S5. The terminal locks the settlement area, drives the displacement unit to move the camera 4 to the vicinity of the settlement area, and transmits the content captured by the camera 4 to the alarm center through the wireless module to give an alarm, facilitating remote observation of the settlement situation and discussing repair or evacuation plans;

[0041] S6. The terminal divides the settlement levels according to the difference between the monitored data and the initial data, and transmits different display signals to the display unit 8 according to the settlement levels, so that the display unit 8 displays different contents.

[0042] Specific working principle and usage method:

[0043] Step 1: Install multiple pipes 3 and multiple pressure sensors on the inner wall of the tunnel 1, making the multiple pressure sensors form a grid. Then fill the pipes 3 with liquid. At this time, detect the water pressure in the pipes 3 through the pressure sensors, and use this detected data as the initial data;

[0044] Step 2: Monitor the water pressure in the pipes 3 in real time through the pressure sensors, and transmit the monitored data to the terminal. Compare the monitored data with the initial data through the terminal. If there is a difference between the monitored data and the initial data, it means that the inner wall of the tunnel 1 has settled;

[0045] Step 3: Divide the settlement levels according to the difference between the monitored data and the initial data, that is, the greater the difference between the monitored data and the initial data, the more serious the settlement degree. The terminal transmits different display signals to the display unit 8 according to the settlement levels A, B, and C, prompting the display unit 8 to display a speed limit of 60, a speed limit of 40, and no passage.

[0046] Step 4: The grid formed by the multiple pressure sensors facilitates the division of the monitoring area. When a certain area on the inner wall of the tunnel 1 settles, the terminal can quickly lock the settlement area, transmit a movement signal to the displacement unit, drive the displacement unit to move to the settlement area, and then take pictures of the settlement area through the camera 4;

[0047] Step 5: The video captured by the camera 4 is transmitted to the alarm center through the wireless module, facilitating the staff of the alarm center to directly observe the settlement situation and discuss repair or evacuation plans accordingly.

[0048] That is, by laying pipes 3 filled with liquid and pressure sensors on the inner wall of the tunnel, and monitoring the water pressure in the pipes 3 in real time through the pressure sensors, transmitting the monitored data to the terminal, and the terminal judges whether the inner wall of the tunnel 1 has settled according to whether the monitored data changes; at the same time, the multiple pressure sensors form a structure that facilitates the division of the monitoring area, and when the inner wall of the tunnel 1 settles, it can be quickly located.

[0049] In this embodiment, in S1, a plurality of pipes 3 are arranged uniformly along the circumferential direction of the tunnel 1, and each pipe 3 extends along the length direction of the tunnel 1. Then, each pipe 3 is fixed by the mounting frame 2, and a plurality of pressure sensors are uniformly installed on each pipe 3 along the length direction of the pipe 3.

[0050] A plurality of pipes 3 are longitudinally distributed uniformly in the tunnel 1, and a plurality of pressure sensors are respectively distributed uniformly along the length direction of the plurality of pipes 3;

[0051] The pressure sensors on a single pipe 3 form a longitudinal column, and the pressure sensors on adjacent pipes 3 form a transverse column. In this way, a grid-like structure is formed by a plurality of pressure sensors, which is convenient for the terminal to divide the settlement area.

[0052] In this embodiment, in S1, after the pipe 3 and the pressure sensors are installed, water is conveyed inside the pipe 3, and then the water pressure inside the pipe 3 is monitored by the pressure sensors, and the initial value is extracted as the initial data.

[0053] In this embodiment, in S2, a grid-like structure is formed by a plurality of pressure sensors, and the terminal can form corresponding coordinate positions according to the plurality of pressure sensors in the grid-like structure.

[0054] The pressure sensors are numbered according to their positions, and the monitoring areas in the tunnel are divided by the numbers, which is convenient for positioning the settlement area later.

[0055] When the settlement of the inner wall of the tunnel 1 causes extrusion on the pipe 3, the water pressure inside the pipe 3 in the settlement area is increased, and then the value detected by the pressure sensor will also be larger; the pipe 3 in this area is tilted due to the settlement extrusion, which causes the water pressure inside the adjacent pipes 3 not affected by the settlement to decrease, and then the value detected by the pressure sensor will also be smaller. In this way, the terminal locks the pressure sensors with smaller detected values to form the edge of the settlement area.

[0056] In this embodiment, in S3, the pressure sensors are monitored by the terminal, and the monitoring data is compared with the initial data. If the monitoring data is consistent with the initial data, it means that the tunnel 1 has not settled to cause oppression on the pipe body. If there is a difference between the monitoring data and the initial data, it means that the inner wall of the tunnel 1 has settled.

[0057] In this embodiment, in S5, a guide rod 5 for the displacement unit to slide is installed inside the pipe 3, and the camera 4 is installed on the displacement unit, and the shooting direction is towards the pressure sensors.

[0058] In this embodiment, in S5, the camera 4 is electrically connected to the terminal and the wireless module, and the content captured by the camera 4 is transmitted to the alarm center through the wireless module.

[0059] In this embodiment, in S6, after the inner wall of the tunnel 1 settles, the monitoring data is compared with the initial data to form a difference, and the settlement level is divided according to the magnitude of the difference. The terminal transmits different display signals to the display unit 8 according to the settlement level, prompting different display units 8 to display different speed limit levels or no passage.

[0060] According to the comparison between the monitoring data and the initial data to form a difference, it is divided into three settlement levels. The three settlement levels are A level, B level, and C level from low to high in sequence. And the terminal will transmit signals of speed limit 60, speed limit 40, and no passage to the display unit 8 according to A level, B level, and C level respectively.

[0061] In this embodiment, in S5, the displacement unit includes a guide rod 5, a housing 6 that slidably cooperates with the guide rod 5, and a roller 7. The roller 7 contacts the wall or floor of the tunnel 1.

[0062] The wireless module includes a current converter and a remote transceiver chip. The current converter and the remote transceiver chip are electrically connected, and the current converter is electrically connected to the terminal.

[0063] In this embodiment, in S6, the display unit 8 is a lamp group formed by arranging a plurality of LED lights in a rectangle or a circle.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
