Description

Technical Field

[0001] The present invention relates to the field of tunnel monitoring technology, and in particular to a smart park management and control system. Background Art

[0002] With the continuous development of engineering construction technology and mining technology, various mountain tunnels, undersea tunnels, riverbed tunnels, coal mine tunnels, etc. have emerged. Tunnel excavation is dangerous. In some places prone to faults and insufficient support, collapse accidents are prone to occur, causing casualties. Therefore, early warning of tunnel collapse is necessary.

[0003] The existing tunnel collapse warning equipment uses a laser instrument fixed on the side wall of the tunnel. The laser instrument reflects the reflector on the other side wall to obtain the initial reflection point, and the displacement of the inner wall of the tunnel is understood by measuring the position change of the reflection point. Although this scheme can detect the displacement of rock formations on the inner wall of the tunnel, the optical instrument is placed outside and is easily disturbed by the environment. There is also a lot of interference between the optical instrument and the reflector, such as construction dust in the tunnel. This will cause measurement errors and affect the measurement results, making it impossible for the equipment to issue timely warnings. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a smart park management and control system to solve the problem that the tunnel collapse warning equipment in the prior art uses optical instruments for monitoring, but the optical instruments are easily disturbed by the environment during use, such as construction dust in the tunnel, which causes measurement errors and affects the measurement results, thereby making the equipment unable to issue timely warnings.

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

[0006] A smart park management and control system comprises the following steps: S1, fixing a pipeline and a pressure sensor on the inner wall of a tunnel by means of a mounting frame;

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

[0008] S3, monitoring the water pressure of the pressure sensor, transmitting the monitoring data back to the terminal, and comparing it with the initial data at the time of installation. If the monitoring data does not match the initial data, it means that the inner wall of the tunnel has settled;

[0009] S4. The water pressure inside the pipe pushed out by the tunnel settlement will increase, while the water pressure inside the adjacent pipe not pushed out by the tunnel will decrease relatively. Therefore, the monitoring data transmitted back to the terminal by the pressure sensor is compared with the initial data. The part where the monitoring data is greater than the initial data is explained as the settlement area, and the part where the monitoring data is less than the initial data is explained as the edge of the settlement area.

[0010] S5. The terminal locks the settlement area and drives the displacement unit to move the camera to the vicinity of the settlement area. The camera footage is transmitted to the alarm center through the wireless module and an alarm is issued, so as to facilitate remote observation of the settlement situation and discussion of maintenance or evacuation plans.

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

[0012] It is further defined that in S1, a plurality of pipelines are evenly arranged along the circumferential direction of the tunnel, and each pipeline extends along the length direction of the tunnel, and then each pipeline is fixed by a mounting frame, and a plurality of pressure sensors are evenly installed on each pipeline along the length direction of the pipeline.

[0013] It is further defined that in S1, after the pipeline and the pressure sensor are installed, water is supplied to the inside of the pipeline, and then the water pressure in the pipeline is monitored by the pressure sensor, and an initial value is extracted as initial data.

[0014] It is further defined that in S2, a grid 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 structure.

[0015] It is further defined that in S3, the pressure sensor is 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 has not settled to cause pressure 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 has settled.

[0016] It is further defined that in S5, a guide rod for the displacement unit to slide is installed in the pipeline, and the camera is installed on the displacement unit, and the shooting direction is toward the pressure sensor.

[0017] It is further defined that in S5, the camera is electrically connected to the terminal and the wireless module, and the camera shooting content is transmitted to the alarm center through the wireless module.

[0018] It is further defined that in S6, after the inner wall of the tunnel settles, the monitoring data and the initial data are compared to form a difference, and the settlement level is divided according to the size of the difference. The terminal transmits different display signals to the display unit according to the settlement level, prompting different display units to display different speed limit levels or prohibition of passage.

[0019] It is further defined that in S5, the displacement unit includes a housing and a roller that are slidably matched with the guide rod and the guide rod, and the roller is in contact with the wall or the ground of the tunnel;

[0036] See also Figure 1-4 ,The present invention provides a technical solution: a smart park management and control system, comprising the following steps: S1, fixing a pipe 3 and a pressure sensor on the inner wall of a tunnel 1 through a mounting frame 2;

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

[0038] S3, monitoring the water pressure of the pressure sensor, transmitting the monitoring data back to the terminal, and comparing it with the initial data at the time of installation. If the monitoring data does not match the initial data, it means that the inner wall of the tunnel 1 has settled;

[0039] S4, the water pressure inside the pipe 3 pushed out by the tunnel settlement will increase, and the water pressure inside the adjacent pipe 3 not pushed out by the tunnel will be relatively reduced. Therefore, the monitoring data transmitted back to the terminal by the pressure sensor is compared with the initial data. The part where the monitoring data is greater than the initial data is explained as the settlement area, and the part where the monitoring data is less than the initial data is explained as 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 and issues an alarm, so as to facilitate remote observation of the settlement situation and discussion of maintenance or evacuation plans;

[0041] S6. The terminal classifies the sedimentation level according to the difference between the monitoring data and the initial data, and transmits different display signals to the display unit 8 according to the sedimentation level, so that the display unit 8 displays different contents.

[0042] Specific working principle and usage:

[0043] Step 1: multiple pipes 3 and multiple pressure sensors are installed on the inner wall of the tunnel 1, so that the multiple pressure sensors form a grid, and then the pipes 3 are filled with liquid. At this time, the water pressure in the pipes 3 is detected by the pressure sensors, and the detection data is used as initial data;

[0044] Step 2: The water pressure in the pipeline 3 is monitored in real time by the pressure sensor, and the monitoring data is transmitted to the terminal. The monitoring data is compared with the initial data by the terminal. 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;

[0045] Step 3: Divide the settlement level according to the difference between the monitoring data and the initial data, that is, the larger the difference between the monitoring data and the initial data, the more serious the settlement. The terminal transmits different display signals to the display unit 8 according to the settlement level A, B, and C, prompting the display unit 8 to display the speed limit 60, the speed limit 40, and the prohibition of passage.

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

[0047] Step 5: The video footage captured by camera 4 is transmitted to the alarm center via a wireless module, so that the staff of the alarm center can visually observe the settlement situation and discuss maintenance or evacuation plans.

[0048] That is, by laying a pipe 3 filled with liquid and a pressure sensor on the inner wall of the tunnel, and monitoring the water pressure in the pipe 3 in real time through the pressure sensor, the monitoring data is transmitted to the terminal, and the terminal determines whether the inner wall of the tunnel 1 has settled according to whether the monitoring data changes; at the same time, multiple pressure sensors are constructed to facilitate the division of monitoring areas, and when the inner wall of the tunnel 1 settles, it can be quickly located.

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

[0050] The plurality of pipes 3 are evenly distributed longitudinally in the tunnel 1, and the plurality of pressure sensors are evenly distributed along the length direction of the plurality of pipes 3;

[0051] The pressure sensors on a single pipeline 3 form a longitudinal row, and the pressure sensors on adjacent pipelines 3 form a transverse row, so that a grid is formed by a plurality of pressure sensors, which facilitates the terminal to divide the settlement area.

[0052] In this embodiment, in S1, after the pipeline 3 and the pressure sensor are installed, water is supplied to the inside of the pipeline 3, and then the water pressure in the pipeline 3 is monitored by the pressure sensor, and an initial value is extracted as initial data.

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

[0054] The pressure sensors are numbered according to their locations, and the monitoring areas in the tunnel are divided by numbering to facilitate the positioning of the settlement areas at a later stage.

[0055] When the inner wall of the tunnel 1 sinks and squeezes the pipe 3, the water pressure in the pipe 3 in the sinking area increases, and the value detected by the pressure sensor becomes larger; the pipe 3 in the area is tilted by the sinking, which reduces the water pressure in the adjacent pipe 3 that is not affected by the sinking, and the value detected by the pressure sensor becomes smaller. In this way, the terminal locks the pressure sensor with a smaller detection value and forms the edge of the sinking area.

[0056] In this embodiment, in S3, the pressure sensor is 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 pressure 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 in the pipe 3, and the camera 4 is installed on the displacement unit, and the shooting direction is toward the pressure sensor.

[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 and the initial data are compared to form a difference, and the settlement level is divided according to the size 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 prohibit passage.

[0060] According to the comparison between the monitoring data and the initial data and the difference formed, it is divided into three sedimentation levels, which are A, B and C from low to high, and the terminal will display the speed limit of 60, speed limit of 40 and no-entry signal of unit 8 according to A, B and C respectively.

[0061] In this embodiment, in S5, the displacement unit includes a guide rod 5 and a housing 6 and a roller 7 that are slidably matched with the guide rod 5, and the roller 7 is in contact with the wall or the ground of the tunnel 1;

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

[0063] In this embodiment, in S6, the display unit 8 is a lamp group composed of a plurality of LED lamps arranged in a rectangular or circular shape.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
