Detailed description of the invention
A kind of Intellisense fence for positioning system, as described in Figure 1, it is formed primarily of detection fence 1, detecting unit and at least one detecting sensor 2.
Described detection fence 1 is made up of many upright fence post 1-1 and at least one fence wire 1-2.Upright fence post 1-1 compartment of terrain is built up in the periphery needing zone of protection.Every bar fence wire 1-2 is fixing step by step and horizontal on above-mentioned upright fence post 1-1.Described detection fence 1 is identical with existing fence or close, but in order to the perception that detecting sensor 2 couples of fence wire 1-2 tilt can be ensured, fence wire 1-2 should keep horizontal-extending state on the whole, if but the horizontal-extending of whole piece fence wire 1-2 can not be guaranteed, but at least will ensure that the fence wire 1-2 between every 2 upright fence post 1-1 extends horizontally.
Each detecting sensor 2 forms by the ball switch of 2 horizontally sets.On arrangement mode, the first ball switch 2-1 and the second ball switch 2-2 can adopt front and back set-up mode, also can adopt mode setting up and down.In the utility model preferred embodiment, the first ball switch 2-1 and the second ball switch 2-2 adopts mode setting up and down.In order to perceive being inclined upwardly or downward-sloping motion of fence wire 1-2 simultaneously, above-mentioned 2 ball switch adopt parallel way in the other direction to connect: namely the trigger end of the first ball switch 2-1 is towards left side, and non-touch is made a start towards right side; The trigger end of the second ball switch 2-2 is towards right side, and non-touch is made a start towards left side.2 ball switch preferably can the severity i.e. axis of 2 ball switch all equal with horizontal plane, but consider that the horizontal Trigger Angle of the sensitive precision of ball switch self and ball switch is minimum (through actual measurement, about about 1.2 degree steady closure), should and angle cannot meet practical application scene fence wire 1-2 tilt trigger requirement, in addition, also consider that fence wire 1-2 is difficult to accomplish the problem of severity, two ball switch be fixed in mounting box need to be biased in advance a suitable angle, namely there is certain angle between the first ball switch 2-1 and horizontal plane and/or there is certain angle between the second ball switch 2-2 and horizontal plane.In the utility model, the angle between the first ball switch 2-1 and horizontal plane, and the angle between the second ball switch 2-2 and horizontal plane is all between 2 ° ~ 6 °.In the utility model preferred embodiment, the angle between the first ball switch 2-1 and horizontal plane, and the angle between the second ball switch 2-2 and horizontal plane is 3.4 °.Trigger end and the second ball switch 2-2 non-touch of the first ball switch 2-1 are made a start and are connected and form a perception end of detecting sensor 2.The non-touch of the first ball switch 2-1 is made a start and to be connected with the second ball switch 2-2 trigger end and to form another perception end of detecting sensor 2.See Fig. 2.When A holds relative level downward-sloping, the ball in the ball switch of top rolls to A end, triggers short circuit; When B holds relative level downward-sloping, the ball in the ball switch of below rolls to B end, triggers short circuit; During AB level, upper and lower two ball switch are all in open-circuit condition.
Described detecting sensor 2 level is arranged on fence wire 1-2.For same fence wire 1-2, in order to better detection and localization can be realized, and ensure positioning precision, the fence wire 1-2 between every 2 upright fence post 1-1 is equipped with at least 1 detecting sensor 2.And in order to the perceptual sensitivity of sensor can be improved, in the utility model preferred embodiment, fence wire 1-2 between every 2 upright fence post 1-1 is provided with 2 detecting sensors 2, one of them detecting sensor 2 is near the upright fence post 1-1 in left side, and another detecting sensor 2 is near the upright fence post 1-1 on right side.The utility model by a large amount of detecting sensor 2 of existing fence deploy, judges whether fence wire 1-2 on fence is touched and produces, thus judging whether that someone carries out for passing through.Each detecting sensor 2 be arranged on same fence wire 1-2 adopts parallel way to couple together, and in the horizontal holding wire 3 disposed of access.Detecting sensor 2 differentiates by built-in ball switch the generation that fence wire 1-2 tilts, when the fence wire 1-2 run-off the straight of fence wire 1-2 fence, the tilt switch be originally under normally open occurs closed (i.e. short circuit).
Detecting unit is made up of power supply and the man-machine interface be connected with power supply, control treatment module, pulse generating module and reception of impulse module.Man-machine interface is connected with control treatment module, the output of control treatment module is connected with the input of pulse generating module, the output of pulse generating module connects a perception end of each detecting sensor 2 through holding wire 3, the input of reception of impulse module connects another perception end of this detecting sensor 2 through holding wire 3, the input of control treatment module is connected with the output of reception of impulse module.Specifically arranging, in order to detecting sensor 2 can be allowed to communicate with detecting unit, needing, a signal line 3 is set in addition on the bearing of trend along fence wire 1-2 and realizes.See Fig. 3.Control treatment module includes MCU microcontroller, input for responding man-machine interface arranges and the detected parameters (as alarm status and warning position etc.) after calculation process is shown in man-machine interface, occurs and reception of impulse module for control impuls simultaneously; Power module is used for module for power supply each in whole detecting unit.Regularly patrolling and examining parameter as arranged by man-machine interface is 2 seconds, so controller processing module produces a narrow-band impulse voltage signal (as 36V) every 2 seconds enabling pulse generation modules, and this pulse signal injects detecting sensor 2 array by holding wire 3A.When there being certain sensor to produce short-circuit signal in detecting sensor 2 array, so pulse signal is gone back in holding wire 3B by open circuit place, returns to reception of impulse module and receives, and reception of impulse module notice control treatment module receives echo-signal.The time difference that controller processing module is come and gone by calculating impulse ejection and echo impulse, thus calculate short circuit distance by following formula (1) echo-bearing distance algorithm, namely locating people is the position passing through generation.Because holding wire 3 end loopback, if so be short-circuited without any sensor in sensor array, so pulse signal will return reception of impulse module (time difference is now echo maximum time difference) by end, holding wire 3 tunnel.
The operation principle of said system is as follows:
(1) generation of detecting sensor 2 short-circuit signal
People is to pass through fence wire 1-2 fence, need up-down stretch fence wire 1-2, when there is pulling action, the detecting sensor 2 be arranged on fence wire 1-2 follows inclination, closes formation short circuit in the ball switch being mounted in detecting sensor 2 inside because of inclination.When inclination sensor internal short-circuit, if there is pulse voltage signal to inject, signal by turning back herein, will turn back to reception of impulse module and receives.The short-circuit point of ball switch can be preset as required, preset 3 ° of such as angle.When θ angle is greater than 3 °, generation short circuit is closed, so the trigger sensitivity of detecting sensor 2 can be controlled.
(2) echo-bearing distance algorithm
The general principle of native system is first to holding wire 3 first sections of injected pulse voltage signals, and the two-way time according to transmitted pulse and echo impulse differs from and the spread speed of pulse in wire, just can calculate the distance of abnormity point, see formula (1):
L＝(V×△t)/2 (1)
Wherein, L be on holding wire 3 detecting sensor 2 at a distance of the distance (m) of detecting unit position, V is the spread speed of pulse voltage signal in wire (m/s) (value is light velocity 299792458m/s), and △ t is the time difference (s) between transmitted pulse and echo impulse.
Citing: existing fence wire 1-2 fence total length is 5000m, if produce the action of artificial stretching fence wire 1-2 in certain distance, tilt switch in the detecting sensor 2 of at this moment position is herein closed produces short circuit, pulse voltage signal passes through from here, and the time difference that detecting unit records between transmitted pulse and echo impulse is 26.6851us, brings formula (1) into and calculate:
L＝(V×△t)/2＝(299792458m/s×26.6851us)/2≈3999.99586m
Namely drawing has people for passing through action about 4000m position, so the man-machine interface of detecting unit sends alarm and shows abnormity point positional information.
