Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

An intelligent protective net, as shown in fig. 1, comprises a protective net and a displacement sensor 1; when in use, firstly, the protective net is fixedly arranged on the ground along the vertical direction; the fixing of the protective net can be that both ends of the protective net are directly fixed on a wall, or that the two ends of the protective net are fixedly provided with the upright posts 7, and the upright posts 7 are fixedly arranged on the ground, no matter which fixing mode is adopted, the bottom of the protective net can be in contact with the ground or not, when the bottom of the protective net is not in contact with the ground, the distance between the bottom of the protective net and the ground is not too large, otherwise, illegal persons can directly climb into a forbidden zone through the distance between the bottom of the protective net and the ground; secondly, digging pits on the ground below the protective net, arranging the displacement sensors 1 in the pits at equal intervals, and filling and tamping the pits; in order to enable the displacement sensor 1 to trigger an alarm no matter where the illegal person begins to dig the pit, the distance between the displacement sensor 1 and the ground cannot be too large, and the distance between two adjacent displacement sensors 1 cannot be too wide, in the embodiment, the height between the displacement sensor 1 and the ground cannot exceed 20cm, and the distance between two adjacent displacement sensors 1 is set to be 50 cm.

The forbidden zone in this embodiment may be an area where no non-workers enter, an area where no workers enter through a regular channel, or the like.

In order to avoid illegal persons from entering a restricted area, a protective net is usually arranged near the restricted area, in the prior art, in order to detect whether a person enters the restricted area by climbing the protective net, a pressure sensor is usually arranged on the protective net, and when the illegal persons climb the protective net, the pressure sensor can trigger alarm information, so that the illegal persons can conveniently find and process the alarm information in time; however, the method is only suitable for the mode that illegal persons enter the forbidden zone by climbing the protective net, and when the illegal persons enter the forbidden zone from the lower part of the ground by digging holes, an alarm signal cannot be triggered; based on this, this scheme is provided with displacement sensor 1 in the below ground, and displacement sensor 1 is connected with alarm system, and when illegal personnel lead to displacement sensor 1 to take place the displacement at the excavation in-process, displacement sensor 1 triggers alarm signal to make things convenient for the timely discovery of personnel on duty and handle.

Further, as shown in fig. 3 and 4, the displacement sensor in this embodiment includes a fixing end 2 and a detecting end 3, the fixing end 2 is a cone structure, and the bottom of the fixing end 2 is fixedly connected to the detecting end 3.

Considering that most of the existing displacement sensors 1 are of square structures and buried in the ground, the existing displacement sensors 1 are in plane contact with the ground, and the state of the displacement sensors 1 is not easy to change, in this embodiment, the structure of the displacement sensors 1 is correspondingly improved, so that the fixed ends 2 of the displacement sensors 1 are set to be of a cone structure, when the displacement sensors 1 are buried in the ground, the contact of the displacement sensors 1 with the ground is curved surface contact, and when illegal persons dig holes in the lower portion of a protective net, the state of the displacement sensors 1 is easy to change, and an alarm signal is easy to trigger.

Further, in order to avoid that an illegal person enters the forbidden area by destroying the grid net 4, the transverse connecting rib 5 of the guard rail is further improved in the embodiment, as shown in fig. 2, in the prior art, the transverse connecting rib 5 is of a solid structure, the transverse connecting rib 5 in the embodiment is of a hollow structure, the sensing circuit 6 is arranged inside the transverse connecting rib 5, and when the illegal person destroys the grid net 4 (cuts off the transverse connecting rib 5), the sensing circuit 6 is also destroyed, so that an alarm signal can be triggered, and the illegal person on duty can find and process the alarm signal in time.

During concrete implementation, for the convenience of laying of the sensing circuit 6, the two adjacent transverse connecting ribs 5 are communicated, and in every three transverse connecting ribs 5, one end of the middle connecting rib is communicated with the upper connecting rib, and the other end of the middle connecting rib is communicated with the lower connecting rib.

Further, in order to facilitate laying of the protective net at a position without a wall or a support, the columns 7 are fixedly provided on both end surfaces of the grille net 4 in the present embodiment, and the grille net 4 is fixedly provided on the ground by fixedly providing the columns 7 on the ground.

Furthermore, in order to prevent illegal people from easily crossing the protection net, a blocking net 8 is arranged above the protection net along the length direction of the protection net.

Specifically, the column 7 in this embodiment is a Y-shaped structure, the blocking net 8 includes a first blocking net and a second blocking net, two ends of the first blocking net 8 are welded to one branch of the V-shaped branch, two ends of the second blocking net are welded to the other branch of the V-shaped branch, and bottoms of the first blocking net and the second blocking net are both welded to a junction of the two branches.

In the embodiment, the upright post 7 is arranged in a Y-shaped structure, and the blocking net 8 is arranged on the Y-shaped structure, so that illegal persons cannot provide an acting point when crossing the guard rail due to the fact that the blocking net 8 extends towards two sides of the axis of the upright post 7, and the crossing resistance is increased.

Further, since the blocking net 8 in this embodiment is in a V-shaped structure, even if a lawbreaker uses a foreign tool (such as an escalator) to climb over the guard rail, the lawbreaker inevitably enters the space in the V-shaped blocking net 8 and extrudes the blocking net 8 to generate deformation, and based on this, in this embodiment, the blocking net 8 is further provided with an inclination angle sensor 9, and when the blocking net 8 deforms, an angle detected by the inclination angle sensor 9 changes, so as to trigger an alarm signal.

Further, considering that some protective nets are arranged beside the trees, when the leaves are blown by wind, the leaves can drive the blocking net 8 to move, so that false alarm of the tilt angle sensor 9 is caused. Based on this, the tilt sensor 9 in this embodiment is improved correspondingly, and specifically, the tilt sensor 9 in this embodiment includes an angle detection module, a time detection module, a storage module and a control module, where the angle detection module is used to detect angle information, the time detection module is used to detect time information, and the storage module stores preset threshold angle information and threshold time information; when the angle information detected by the angle detection module is greater than the threshold angle information, the controller controls the time detection module to detect the time information, and when the detected time information is greater than the threshold time information, the control module outputs an alarm signal. In this embodiment, the condition that the tilt sensor 9 triggers the alarm signal includes threshold angle information and time information, and compared with a single alarm based on the angle information, the false triggering alarm rate is reduced.

It should be noted that, the controller receives an input signal and outputs another signal according to the input signal, which is the prior art, and the present application is only applied to this scheme and does not relate to the improvement of the program.

Further, the tension wire is also included, as shown in fig. 5, the tension wire in this embodiment includes a pressure sensor (not shown), a tension pulley 10, an alloy wire, and a spring 12 for increasing the ductility of the alloy, the tension pulley 10 is adjusted to adjust the tightness of the alloy wire, and when the pressure value applied to the alloy wire from the outside is greater than a threshold pressure, an alarm signal is triggered. Preferably, to avoid an alarm caused by the animal staying on the tension wire, the threshold pressure may be set slightly larger so that the alarm signal is only triggered when someone climbs or cuts the alloy wire.

During specific implementation, according to the protection requirement, the tension lines can be arranged above the blocking net 8 at intervals along the length direction of the grille net 4, and the blocking net 8 can also be replaced by the tension lines, so that a tension fence is formed. When the tension line is arranged above the blocking net 8, a supporting rod can be welded at the junction point (the joint of the V-shaped structure and the vertical structure) of the Y-shaped upright post 7, and the end face of the tension line is fixedly arranged on the supporting rod. When the tension wire replaces the blocking net 8, the tension wire is arranged on the two branches of the V-shaped structure.

When the protective net is used, the collectors 11 used for collecting signals of the sensors can be arranged on the protective net, the signals are transmitted to the alarm system through the collectors 11, and the signals collected by the sensors can also be directly transmitted to the alarm system. In this embodiment, in order to save cost, the output end of each sensor is connected to the input end of the collector 11 through a connecting line, a data transmission line is reserved at the output end of the collector 11, and when the protection net is concrete, the data transmission line is connected to the alarm system.
