In the important security fields of airports, national border lines, land ports, ammunition libraries, high-speed rails, high-grade security units, nuclear power plants, oil reservoirs and the like, the security fields are generally isolated or protected by adopting the means of physical protection and/or technical protection, wherein the existing physical protection means mostly play a pure role in physical isolation or protection by arranging wire nets, rope-punching nets, rolling cage nets, iron fences and the like. However, if the invasion actions such as wire netting, rope punching net, rolling cage net and the like are damaged, unless someone timely discovers or installs video monitoring, a great potential safety hazard exists. The existing technical prevention means is to add technical prevention equipment such as laser correlation, radar, infrared correlation, electronic fence, vibration optical cable and the like on the premise of installing an iron wire net and a rope net. However, the existing technical protection equipment is relatively backward in technology, is easily influenced by wind, snow, ice, fog and other interference factors, and meanwhile, the surrounding environments such as high and low temperature, sun, plant trees and the like can influence the accuracy of the equipment, so that the equipment has the defect of high false alarm rate, and the popularization and application values of the existing technical protection means are relatively limited.

The technical problem solved by the utility model is to provide the protective net with the monitoring function besides the physical blocking function, so that the protective net can physically play a role in isolating and protecting a common protective fence or a steel wire rope protective net, and can also transmit monitoring information, thereby technical protection equipment such as infrared correlation, laser correlation, radar, vibration optical cables, pulse electronic fence and the like are not required to be additionally arranged.

In order to solve the technical problems, the utility model provides three technical schemes. The first technical scheme provided by the utility model is as follows: the protection net with the monitoring function comprises at least one net body unit, wherein the net body unit comprises a plurality of longitudinal pipes and a plurality of transverse pipes, the longitudinal pipes and the transverse pipes are in cross connection, and current can be transferred between the longitudinal pipes and the transverse pipes; the net body unit further comprises a first wire and a second wire, one end of the first wire is electrically connected with the current monitoring control module, the other end of the first wire sequentially penetrates through the inner cavities of all the longitudinal pipes and then is subjected to insulation treatment, one end of the second wire is electrically connected with the current monitoring control module, and the other end of the second wire sequentially penetrates through the inner cavities of all the transverse pipes and then is subjected to insulation treatment. Therefore, when the protective net provided by the utility model is in a normal state, the first wire and the second wire are in a disconnected state, the first wire and the second wire respectively form an open circuit, and the current amounts of the two open circuits are zero or approximately zero. When the protective net provided by the utility model is damaged, namely when the longitudinal pipe and the transverse pipe are sawn or sheared, the shearing points of the longitudinal pipe and the transverse pipe are flattened until the two pipe walls are contacted due to the pressure applied to the longitudinal pipe and the transverse pipe by tools such as scissors pliers, and one or two breaking points of the first lead and the second lead which are corresponding to each other are clamped after the shearing points of the longitudinal pipe and the transverse pipe are sheared, so that the first lead and the second lead form a complete closed loop through the longitudinal pipe and the transverse pipe which are connected with each other, and the current values of the first lead and the second lead are changed. Therefore, after the current values of the first wire and the second wire are changed due to the fact that the net body unit is damaged, the current monitoring control module can timely monitor the current change and send out corresponding alarm prompt information when the current is monitored to change and then continuously and stably output, and accordingly workers are reminded that the protection net is damaged at the moment.

Further, one or at least two first leads penetrate through the inner cavity of each longitudinal tube; one or at least two second leads penetrate through the inner cavity of each transverse tube, and the specific values of the first leads and the second leads can be flexibly changed according to the inner diameter of the longitudinal tube and the inner diameter of the transverse tube respectively, so that the longitudinal tube and the transverse tube can clamp the corresponding first leads and second leads when being sheared.

Further, the first wire comprises an information transmission inner core, the information transmission inner core is a metal wire or an optical fiber, and an insulating sheath is sleeved outside the information transmission inner core, so that the first wire is ensured not to conduct current transfer with the longitudinal tube under normal conditions through the insulating sheath.

Further, the intersections of the longitudinal pipes and the transverse pipes are welded or connected through fixing pieces; the longitudinal pipes and the transverse pipes are square pipes or round pipes.

Further, the net body unit further comprises a frame, and the frame is connected with the longitudinal pipes and the transverse pipes, so that when the net body unit is installed, the longitudinal pipes and the transverse pipes can be fixed through the frame, and a group of blocking nets are formed.

Further, the current monitoring control module is in communication connection with the upper computer, so that the staff can conveniently and timely check the alarm prompt information.

The second technical scheme provided by the utility model is as follows: a protective screen with monitoring function, comprising at least one screen body unit, wherein the screen body unit comprises a plurality of longitudinal pipes and a plurality of transverse pipes; the net body unit further comprises a first wire and a second wire, one end of the first wire is electrically connected with the current monitoring control module, the other end of the first wire sequentially penetrates through the inner cavities of all the longitudinal pipes and then is electrically connected with one end of the second wire, and the other end of the second wire sequentially penetrates through the inner cavities of all the transverse pipes and then is electrically connected with the current monitoring control module. Thus, when the protective net provided by the utility model is in a normal state, the first wire and the second wire form a closed loop, and the first wire and the second wire have fixed current amounts. When the protective net is damaged, namely when the longitudinal pipe and the transverse pipe are sawed or sheared, the corresponding first wire and the corresponding second wire inside the longitudinal pipe and the transverse pipe are broken, and a closed loop between the first wire and the second wire is broken, or the first wire and the second wire are respectively contacted with the corresponding longitudinal pipe and the corresponding transverse pipe, so that the resistance value and the current value of the whole circuit are changed. Therefore, after the current values of the first wire and the second wire are changed, the current monitoring control module can timely monitor the current change and send out corresponding alarm prompt information when the current is monitored to change and then continuously and stably output, so that workers are reminded that the protective net is damaged at the moment.

Further, the current monitoring control module is in communication connection with the upper computer, so that the staff can conveniently and timely check the alarm prompt information.

The third technical scheme provided by the utility model is as follows: the protection net with the monitoring function comprises at least one net body unit, wherein the net body unit comprises a plurality of longitudinal pipes and a plurality of transverse pipes, the longitudinal pipes and the transverse pipes are in cross connection, and current can be transferred between the longitudinal pipes and the transverse pipes; the net body unit further comprises a first wire and a second wire, one end of the first wire is electrically connected with the current monitoring control module, the other end of the first wire sequentially penetrates through the inner cavities of all the longitudinal pipes and then is electrically connected with one end of the second wire, and the other end of the second wire sequentially penetrates through the inner cavities of all the transverse pipes and then is electrically connected with the current monitoring control module; the net body unit further comprises a third wire and a fourth wire, one end of the third wire is electrically connected with the current monitoring control module, the other end of the third wire sequentially penetrates through the inner cavities of all the longitudinal pipes and then is subjected to insulation treatment, one end of the fourth wire is electrically connected with the current monitoring control module, and the other end of the fourth wire sequentially penetrates through the inner cavities of all the transverse pipes and then is subjected to insulation treatment. At this time, the third technical scheme provided by the utility model combines the two technical schemes, so that the utility model can simultaneously carry out two groups of monitoring, namely whether the protective net is damaged or not can be judged by monitoring whether the circuit break occurs between the first wire and the second wire or not, and whether the protective net is damaged or not can be judged by monitoring whether a closed loop is formed between the third wire and the fourth wire or not. In addition, whether the protective net is damaged can be judged by monitoring whether current turbulence occurs among the first wire, the second wire, the third wire and the fourth wire, so that the accuracy of the whole protective net is improved.

Further, the current monitoring control module is in communication connection with the upper computer, so that the staff can conveniently and timely check the alarm prompt information.

From the above technical scheme, the utility model has the following advantages: firstly, the protective net provided by the utility model has the physical isolation, blocking and protection functions of the common protective fence, and can monitor the current information of the corresponding wires in the longitudinal pipe and the transverse pipe in real time through the current monitoring control module, and accurately send alarm prompt information at the first time when the protective net is damaged, thereby solving the defect that the wire net object protection and technical protection in the traditional security industry are separated, and enabling the wire net object protection and technical protection to be independent of equipment such as infrared, laser, radar, vibration optical cables, pulse electronic fence and the like.

Secondly, the protective net with the monitoring function provided by the utility model is not damaged by external weather factors such as wind, rain, snow, fog ice and the like and interference of weed plants, excavation construction, vehicles and the like, so that the problems of false alarm and the like are avoided, and the safety and reliability are ensured; meanwhile, the reliability of the whole security system can be greatly improved, and the manpower waste and financial waste of security work are avoided.
