Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in the present invention, implement below in conjunction with the present invention
Accompanying drawing in example, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that described reality
Executing example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, ability
The every other embodiment that territory those of ordinary skill is obtained under not making creative work premise, all should belong to this
The scope of invention protection.
Seeing Fig. 1, for the schematic diagram of a kind of security protection wall that the embodiment of the present invention provides, this security protection wall is arranged on
Need to arrange the position of protective barrier, for example, it may be open region, as at an enclosure wall or other easily plough under or
The position routed up.
As it is shown in figure 1, described security protection wall includes the multiple scattered detector set being arranged in security protection region.
Detector in the present embodiment is duplex communication, it is possible to launch/receive wireless signal.Described detector set includes one
Launch the emitter-detector of wireless signal and at least one receive the pick-up probe of wireless signal, at least one pick-up probe and
One emitter-detector transmitting/receiving wireless signal constitutes wireless signal radiation area.Such as, certain detector set includes that is launched a spy
The ratio of emitter-detector and pick-up probe in device and a pick-up probe, i.e. this detector set of surveying is 1:1；Or,
Certain detector set includes emitter-detector in an emitter-detector and at least two pick-up probe, i.e. this detector set
With ratio 1:n of pick-up probe, wherein, n is the positive integer more than 1.Wherein, sending out in different detector set
The ratio penetrating detector and pick-up probe can be different.
Or, in described detector set, each detector is transmitting-receiving detector, and mutual transmitting/receiving wireless signal constitutes wireless signal spoke
Penetrate district.
Specifically, in this embodiment, it is preferred that use same detector to be only operated under single-mode, i.e. detector is as connecing
Receive the pick-up probe of wireless signal, or for launching the emitter-detector of wireless signal.
It should be noted that the line between emitter-detector and pick-up probe is served only for showing emitter-detector and connecing in Fig. 1
Receive the corresponding relation of detector, the radiation area of the wireless signal being not intended to represent between emitter-detector and pick-up probe.
The wireless signal that detector is launched is distributed in the solid space around emitter-detector, for example, it may be 360 °
Solid space scope, it is intended that 180 ° of direction, 90 ° or the three-dimensional sense of other predetermined angle.
When being embodied as, the concrete scene in the region that can set up defences as required determines that emitter-detector launches wireless signal
Direction, such as, when preventing object from intruding into inside, security protection region, can make territory, safety protection region circumference dispose
Emitter-detector is towards security protection areas outside emission detection signal, so, when there being object near security protection wall,
Security protection wall can be quickly detected invader.When the people prevented in security protection region or object rout up this region,
Can make emitter-detector that territory, safety protection region circumference disposes towards emission detection signal inside security protection region, so,
When there being object near security protection wall in security protection region, security protection wall can be quickly detected invader.
Carry out wireless signal transmitting-receiving between emitter-detector and pick-up probe in each detector set, spatially formed
Wireless signal radiation area, multiple wireless signal radiation areas that multiple detector set are formed overlap each other, and form continuous seamless gap
Microwave array.
In the embodiment of the present invention, this wireless signal can be microwave signal, and microwave is a specific band in electromagnetic wave,
Refer generally to the frequency range that frequency is 300MHz～300GHz,.When not having intrusion behavior, described microwave array is in the most steady
Fixed state.When there being intrusion behavior, microwave signal is during spatial transmission, when running into the barrier such as people or object,
Can reflect, diffraction etc. changes, thus changes original propagation path, so that the energy that microwave signal is in space
There is disturbance in distribution.Concrete, after invader swarms into safety protection region, wireless signal passes rapid decay after invader,
Thus cause the intensity of the microwave signal that pick-up probe receives to die-off.Utilize this characteristic of microwave signal to detect peace
In full protection region, whether object is swarmed into.Any once invade the detectable signal spoke that all can cause adjacent multiple detector set
Penetrate the disturbance of field, according to fluctuation detecting signal situation and the deployed position of detector of multiple detector set, determine and invade
Enter the invasion position of thing.And, according to this joint-detection mode, it is possible to be detected simultaneously by the invasion position of multiple invader.
When being embodied as, reception signal is sent to monitoring backstage by the pick-up probe in the plurality of detector set, monitors backstage
Quantity, position and the amplitude of variation undergone mutation according to signal calculates stop absorptance and the reflection coefficient of object, can distinguish
The volume of intrusion object, kinestate, movement locus etc. determine the invader of invasion microwave array.Such that it is able to by toy,
The interference filtering of trees etc.；Changes in weather can also be filtered out by dynamic calculation, such as, the large area such as rain, snow, wind, little
The interference that the signal intensity of amplitude causes.
Described reception signal is that pick-up probe receives signal produced by the wireless signal that corresponding emitter-detector is launched, described
Receive the signal strength information of the wireless signal that signal at least includes that pick-up probe receives.Described reception signal reporting gives monitoring
The mode on backstage can be that bus reports, wireless mode reports, the invention is not limited in this regard.
Further, it is also possible to according to the position of security protection wall in security protection region, divide warning region and prewarning area,
Such as, prevent object from entering a certain region, can will dispose in the region of security protection cable distance area to be protected farther out
Region is defined as prewarning area, is defined as in region nearer for distance area to be protected in the region of deployment security protection cable alert
Guard against region.Wherein, the threshold value of the fluctuation detecting signal of warning region is more than the thresholding of the fluctuation detecting signal of prewarning area
Value.When invader is close to prewarning area, dissuasion invasion of warning can be broadcasted and occur；When invader is in warning region,
Directly make intrusion reply reaction.
