In invasion position detecting device disclosed by the invention, when entering zone of protection when there being people and hold two plain conductors, two plain conductors connect by hand, and electric resistance measuring apparatus measures the resistance value A of two plain conductor initiating terminals in real time, monitoring client calculates the distance L of invasion point to monitoring client according to the resistance per unit length value S of the resistance value Rhand of this resistance value A, human hands and plain conductor, thus judge the position of invasion point, realize furnace-incoming coal.The structure of this invasion position detecting device is simple, with low cost, is applicable to the occasion being applied in the strick precaution of needs perimeter security and intrusion alarm.
Accompanying drawing explanation
Fig. 1 is the composition structural representation that the present invention invades position detecting device first embodiment.
Fig. 2 is the composition structural representation that the present invention invades position detecting device second embodiment.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in more detail.
Embodiment 1:
The present embodiment proposes a kind of invasion position detecting device, as shown in Figure 1, it comprises along two of the erection of zone of protection circumference parallel plain conductors 1 and monitoring client, described monitoring client measures the resistance value A of two plain conductor 1 initiating terminals by an electric resistance measuring apparatus 2, and utilizes following formulae discovery to invade the distance L of point to monitoring client:
In formula, Rhand is the resistance value of human hands, and this Rhand value is the average resistance of the human hands of being tried to achieve by a large amount of data measured, and S is the resistance value of plain conductor 1 unit length.The derivation of above formula is as follows:
The resistance value A=2R1+Rhand that electric resistance measuring apparatus 2 is measured, R1 are the resistance values of the single piece of metal wire 1 between invasion point and monitoring client, then extrapolate
the wherein resistance value S known constant of the unit length of plain conductor 1, thus, invasion point is to the distance of monitoring client
namely obtain
Wherein, monitoring client can be computing machine, and electric resistance measuring apparatus 2 is integrated within computing machine, but in other embodiments of the invention, this monitoring client also can be specific industrial control equipment.In actual applications, every two plain conductors 1 are set to one group, therefore, can organize plain conductor, thus sensing passage are organized in formation more along the erection of zone of protection circumference more.Preferably, described plain conductor 1 is aluminum stranded conductor.
As a kind of optimal way, also comprise the railing along the erection of zone of protection circumference, described plain conductor 1 is located on railing, distance between two plain conductors 1 is preferably 0.3cm ~ 10cm, but this is only a preferred embodiment of the present invention, be not limited to the present invention, in other embodiments of the invention, the distance between two plain conductors 1 can also adjust according to actual needs and flexibly.
In the present embodiment, the end of two plain conductors 1 is unsettled, and thus, two plain conductors 1, only when there being people to invade, just form loop.
On the basis of above-mentioned invasion position detecting device, the present embodiment also proposes a kind of invasion method for detecting position, and the method comprises the steps:
Step S1, sets up two parallel plain conductors 1 along zone of protection circumference;
Step S2, electric resistance measuring apparatus 2 measures the resistance value A of two plain conductor 1 initiating terminals;
Step S3, monitoring client utilizes following formulae discovery to invade the distance L of point to monitoring client:
In formula, Rhand is the resistance value of human hands, and S is the resistance value of plain conductor 1 unit length.
Above-mentioned invasion position detecting device and invasion method for detecting position in, when entering zone of protection when there being people and hold two plain conductors 1, two plain conductors 1 connect by hand, and electric resistance measuring apparatus measures the resistance value A of two plain conductor 1 initiating terminals in real time, monitoring client calculates the distance L of invasion point to monitoring client according to the resistance per unit length value S of the resistance value Rhand of this resistance value A, human hands and plain conductor 1, thus judge the position of invasion point, realize furnace-incoming coal.The structure of this invasion position detecting device is simple, with low cost, is applicable to the occasion being applied in the strick precaution of needs perimeter security and intrusion alarm.
Embodiment 2:
Please refer to Fig. 2, the difference of the present embodiment and embodiment 1 is, the end of two plain conductors 10 is connected by pull-up resistor 40, the effect of this pull-up resistor 40 is for electric resistance measuring apparatus 20 provides load, avoid electric resistance measuring apparatus 20 unloaded, and then improve the sensitivity of measurement result, in practical application, the resistance of this pull-up resistor 40 is preferably much larger than human hands resistance value, thus when hand holds two plain conductors 10, the resistance value after hand, pull-up resistor 40 and plain conductor therebetween 10 parallel connection is close to human hands resistance value.
Invasion position detecting device disclosed by the invention, monitoring client can calculate the distance of invasion point to monitoring client according to the resistance value A that electric resistance measuring apparatus is measured, thus location invasion point, this whole safeguard fence structure is simple, with low cost, is applicable to the occasion being applied in the strick precaution of needs perimeter security and intrusion alarm.
The above is preferred embodiment of the present invention, is not limited to the present invention, all make in technical scope of the present invention amendment, equivalent to replace or improvement etc., all should be included in scope that the present invention protects.
