Slope protection network node monitoring system

Technical Field

The application relates to the field of slope protection technology, in particular to a slope protection net node monitoring system.

Background

The side slope refers to the general name of slope forms such as natural slopes, river water bank slopes, tablelands, landslide fluid accumulation bodies, artificial slopes and the like. Rock on the general side slope can appear loosening and collapse's condition after long-term rainwash, in order to avoid rock to drop and cause the injury to passing vehicles or pedestrian, can set up the protection network on the side slope surface to intercept the falling stone generally.

In the related art, the protection net is fixed by an anchor assembly. The anchor assembly includes a bolt, an anchor plate, and a nut. The fixing process comprises the following steps: first, a hole is drilled in the side slope, and then an anchor rod is inserted into the hole and grouting is performed. After the anchor rod is fixed, the protective net is sleeved on the anchor rod, and the anchor plate and the nut are sequentially installed on the anchor rod. The anchor plate provides anchor supporting force by extruding the surface of the surrounding rock, so that the surrounding rock is in a stressed state. After the nut is locked, the anchor plate can restrict the surrounding rock from deforming.

However, the anchor assembly is provided in the open air, and is susceptible to failure due to various environmental factors, so that the protection net loses protection function. Therefore, the state of the protection net needs to be monitored.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 and the embodiment. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The embodiment of the application discloses a slope protection network node monitoring system. Referring to fig. 1, the monitoring system for the nodes of the side slope protection network comprises a pull rope, a tension detection unit 1, a timing unit 2, a ranging unit 3, a first control unit 4, a second control unit 5, an alarm unit 6, a communication unit 7 and a power supply module 8, and can monitor the service condition of the protection network and timely find abnormal anchor rods in the protection network so as to reduce the possibility of failure of the protection network.

The tension detection unit 1 is fixed between the two anchor rods through a pull rope and is used for detecting the tension of the anchor rods and outputting a tension detection signal. It will be appreciated that in general the tension detecting unit 1 has a measuring end. In the use process, the measuring end is connected with the measured object, and one end of the measuring end far away from the tension detecting unit 1 is connected with other objects. When the measured object applies the acting force, the tension detecting unit 1 can measure the tension of the measured object. Based on this, the measuring end of the tension detecting unit 1 is fixedly connected with one anchor rod, and the end of the tension detecting unit 1 far away from the measuring end is fixedly connected with the other anchor rod, so that the measuring end of the tension detecting unit 1 faces one of the anchor rods. In some specific embodiments, the tension detecting unit 1 and the two anchors may be connected through a pull rope, or the measuring end of the tension detecting unit 1 may be connected with one anchor through a pull rope, the end of the tension detecting unit 1 far away from the measuring end is directly connected with the other anchor, or the end of the tension detecting unit 1 far away from the measuring end is connected with one anchor through a pull rope, and the measuring end of the tension detecting unit 1 is directly connected with the other anchor.

The two anchors connected to the tension detecting unit 1 may be any two anchors. It can be appreciated that in the process of actually installing the protection net, first, a plurality of installation holes for installing the anchor rods need to be formed on the side slope, and the installation holes form an array and are uniformly distributed on the side slope. And then, the anchor rods are inserted into each mounting hole one by one and fixed in a grouting mode. Taking 4 anchors forming a 2×2 array as an example, two anchors connected to the tension detecting unit 1 may be two anchors adjacent to the same row, two anchors adjacent to the same column, or two anchors on a diagonal line.

In the embodiment of the present application, the tension detecting unit 1 is a tension sensor. It should be noted that, when the loosening condition of the anchor rod is detected by the tension, the tension detecting unit 1 needs to be able to detect a specific tension value, so that the pull ropes should be in a stressed state, that is, two pull ropes connected with the tension detecting unit 1 should be straightened to be in a straight state. The pull rope should have elasticity.

The first control unit 4 is connected to the tension detection unit 1, and is configured to receive a tension detection signal, and output a control signal when receiving a tension value change reflected by the tension detection signal. When the first control unit 4 detects a change in the tension value, it is indicated that the bolt has come loose. On the contrary, when the first control unit 4 does not detect the change of the tension value, it indicates that the anchor rod is not loosened, and no control signal is output at this time. Both the tension detection signal and the control signal can be defined as high level signals or low level signals, and the adaptation is specifically required according to the selected device.

When the condition that the anchor rod is loosened is detected, an alarm should be given at the first time so as to inform maintenance personnel of maintenance and reinforcement operation. Thus, the communication unit 7 is connected to the first control unit 4 for transmitting control signals to the terminal device 9 at the far end. The communication unit 7 may employ a mobile communication chip or the like.

The alarm unit 6 is connected to the first control unit 4, and is configured to receive a control signal, and to alarm when receiving the control signal. On the contrary, when the alarm unit 6 does not receive the control signal, the alarm unit 6 does not alarm. The alarm unit 6 can be an audible and visual alarm.

It will be appreciated that when a maintainer receives the alarm information or hears the alarm and checks the situation on site, only two anchors which may be loosened can be determined according to the tension detecting unit 1, but it cannot be determined which anchor is loosened. Therefore, further determination by the timing unit 2 and the ranging unit 3 is required.

The timing unit 2 is used for outputting a trigger signal at intervals of preset time. The preset time can be adaptively adjusted according to actual needs.

The ranging unit 3 is fixedly arranged on the anchor rod, the measuring end faces the slope, and the ranging unit is electrically connected with the first control unit 4 and the timing unit 2 respectively and is used for receiving the trigger signal and the control signal, measuring the distance from the slope when receiving the trigger signal or the control signal and outputting a distance detection signal. It will be appreciated that since the ranging unit 3 is fixed to the anchor rod, the position of the ranging unit 3 will also change as the anchor rod is loosened. Therefore, the change of the distance between the ranging unit 3 and the slope can be accurately measured by orienting the measuring end towards the slope. The distance measuring unit 3 can realize the function of timing distance measurement under the drive of the trigger signal, can not only collect distance information, but also save energy.

When the distance measuring unit 3 receives the control signal, it is also possible to measure the distance to the slope. It should be noted that when the control signal appears, it is explained that at least one of the two anchor rods connected with the tension detecting unit 1 is loosened, so that the distance measuring unit 3 is triggered to collect distance information at this time, and whether the anchor rod is loosened can be further determined according to the distance collected by the distance measuring unit 3 currently and the distance collected at the last moment. When the distance measuring unit 3 does not receive the trigger signal and the control signal, the distance is not measured, and the distance detection signal is not output.

In this application, the ranging unit 3 may be a laser ranging device, and the fixing manner of the ranging unit and the anchor rod may be any fixing manner, so long as the measuring end faces the slope.

In order to achieve the above function, a dual input or gate 10 is also provided between the ranging unit 3 and the timing unit 2 and the first control unit 4. One input end of the OR gate 10 is connected with the timing unit 2, the other input end is connected with the first control unit 4, and the output end is connected with the ranging unit 3.

The second control unit 5 is connected to the distance measuring unit 3, and is configured to receive the distance detection signal, and to determine whether the anchor rod is displaced according to the distance value reflected by the distance detection signal when the distance detection signal is received. The second control unit 5 is provided with an algorithm that can realize the corresponding function. The present application is not directed to improvements in algorithms and, therefore, the implementation of the algorithms will not be described in detail.

Likewise, the second control unit 5 is also connected to the communication unit 7, via which communication unit 7 an alarm message can be transmitted to the terminal device 9, so that maintenance personnel can know which anchor rod is loose. In some specific embodiments, the first control unit 4 and the second control unit 5 may be connected to the same communication unit 7, or may be connected to one communication unit 7 respectively.

Of course, the first control unit 4 and the second control unit 5 may be integrated, or the same control chip may be used to implement the functions of the first control unit 4 and the functions of the second control unit 5 at the same time.

In order to ensure that the above-mentioned device has insufficient electric quantity in the actual use process, the power supply module 8 is also used for providing power. Specifically, the power supply module 8 includes a power supply unit 81 and a solar charging panel 82. The solar charging plate 82 is connected with the power supply unit 81, and is used for connecting solar energy, converting the solar energy into electric energy and outputting the electric energy.

The implementation principle of the node monitoring system of the side slope protection network in the embodiment of the application is as follows: the tension detecting unit 1 can detect the tension of the anchor rod, and when the anchor rod is loosened, the tension also changes. Because the first control unit 4 can detect that the pulling force of stock changes, consequently this system can in time discover the abnormal state of protection network. The loose anchor rod can be further determined by arranging the timing unit 2 and the ranging unit 3 so as to be convenient for maintenance personnel to repair.

The foregoing description of the preferred embodiments of the present application is not intended to limit the scope of the application, in which any feature disclosed in this specification (including abstract and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. That is, each feature is one example only of a generic series of equivalent or similar features, unless expressly stated otherwise.
