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. In addition, 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.
Considering that the protective net is basically arranged in the field environment or beside the trees, when the protective net or branches are blown by strong wind, the strong wind or branches can drive the blocking net 8 to reciprocate, so that false alarm of the inclination 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 of a blocking network; the time detection module is used for detecting the duration that the angle information is greater than the threshold angle information, and the storage module stores the preset threshold angle information and threshold duration information; the control module is used for controlling the time detection module to detect the duration when the angle information is larger than the threshold angle information; and the warning device is also used for outputting a warning signal when the angle information is greater than the threshold angle information and the duration is greater than the threshold duration information.
In this embodiment, the condition that the tilt sensor 9 triggers the early warning signal includes threshold angle information and threshold duration information, and compared with the single condition that the alarm is performed according to the angle information, the condition that the wind blows the blocking net or the leaves shake the process, the phenomenon that the blocking net is driven to move repeatedly to trigger the early warning is reduced, and the false triggering rate is effectively reduced.
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 used, the data transmission line is connected to the alarm system.
Example 2

the collector 11 is used for collecting an alarm signal of the protective net; the alarm signal may be generated by one or more of a displacement sensor (hole digging alarm), a sensing circuit (damage alarm) or a tilt sensor (climbing alarm); specifically, the output ends of the displacement sensor, the sensing circuit and the tilt sensor are respectively connected with the input end of the collector 11 through data acquisition lines, and when the displacement sensor generates an alarm signal due to displacement, the sensing circuit generates an alarm signal due to shearing or the tilt sensor generates an alarm signal due to triggering an early warning condition, the alarm signal is transmitted to the collector 11 through the data acquisition lines; during the specific use, this collector 11 can regard as a whole fixed setting on the protection network, also can regard as a collection device to set up alone, in this embodiment, in order to reduce use cost, collector 11 sets up alone as a collection device for gather the alarm signal of a plurality of protection networks.
The collection box is used for transmitting the alarm signal to the management platform, the connection mode of the collection box and the management platform can be wired connection or wireless connection, and reasonable selection is carried out according to actual requirements.
And the management platform stores the numbers of the protective net, the collector 11 and the collection box and the corresponding geographical position information, and is used for identifying the corresponding geographical position according to the alarm signal and the number and giving an alarm.
Further, considering that the protection net may be disposed under a tree (for example, a separation line region between a scenic spot and the outside), branches may be broken and pressed on the blocking net 8 due to strong weather or external interference, so that the shapes of the blocking nets 8 above a plurality of intelligent protection nets are changed and continuously maintained, and an alarm of the tilt angle sensor 9 is triggered. Based on this, the management platform in this scheme still is provided with first judgement module, and when the management platform received a plurality of alarm signals and alarm signal was climbing warning (the alarm signal that inclination sensor 9 produced), it is produced that this alarm signal is influenced by weather or external environment, and the management platform does not carry out alarm processing.
Further, the phenomenon that an illegal person climbs the protective net at a stage when the form of the net blocking 8 is changed after knowing the alarm principle is considered, so that the phenomenon discovered by an attendant is avoided. The management platform in the scheme is also provided with a calculation module and a second judgment module, when the management platform receives a plurality of alarm signals and the alarm signals are climbing alarms (alarm signals generated by the tilt angle sensor 9), the calculation module calculates the average value of the angle information according to the angle information of the alarm signals; the second judgment module is used for comparing the angle information of the alarm signals with the average value of the angle information one by one, and if the angle information of one or more alarm signals is n times of the average value of the angle information, the management platform identifies the geographic position corresponding to the alarm signal and gives an alarm, wherein n is greater than 1.
The present solution is illustrated below by specific examples:
26 intelligent protective nets are sequentially arranged from left to right, the numbers of the intelligent protective nets are A1, A2 and … … A26, one collector 11 controls 26 intelligent protective nets (about 80m), and the collector 11 is installed in the middle of the 26 intelligent protective nets, namely: the left side and the right side of the collector are respectively provided with 13 intelligent protective nets; collectors 11 in every 1km are collected into 1 intelligent collection box (about 13 collectors are respectively numbered as A, B, C … …), collection boxes in Nkm are respectively numbered as N1, N2 and … … Nn, and each collection box is communicated with a management platform through a wireless or wired transmission module. When one or more of the displacement sensor, the sensing circuit or the tilt sensor triggers an alarm, the management platform can identify a specific alarm position according to the number, for example, the 6 th intelligent protection net of the B collector 11 under the N2 collection box triggers an alarm, that is: the N2-B-6 intelligent protection net gives an alarm, and the management platform stores each number and the position information corresponding to each number in advance, so that the alarm position is very accurate, the handling by the duty personnel is convenient, and the maintenance by the maintenance personnel is also convenient.
