Description
Technical field
This utility model be related to electronic technology field and in particular to a kind of apply in tension fence warning system relative
Translation alarm device.
Background technology
Tension fence alarm device is provided with sensor, when invader pulls and connects wire on fence, described sensing
Device exports a signal of telecommunication to control centre, and described control centre reports to the police after receiving output signal immediately.In prior art, described
The sensor of tension fence alarm device, all using resistance-strain chip pressure transducer.Invaded when keeping the scene intact, that is,
When invader produces pulling force on fence, this pulling force is conducted to tension fence alarm device by steel wire rope.Tension fence is reported to the police
When having dynamics change on the sensor senses steel wire rope of device, resistance-strain chip pressure transducer works.Described resistance-strain
The resistance of sheet type sensor has the strain effect of metal, that is, under external force produce mechanical deformation so that resistance value with
Generation corresponding change.The change transitions of resistance value are the change of voltage by small signal amplifier, and filter some environment
In noise jamming, the voltage signal that pulling force is produced pays CPU process.CPU will be according to environmental factorss, and the change of power
After synthesis, carry out determining whether to invade.
However, the resistance-strain chip pressure transducer of application suffers from the drawback that in existing tension fence alarm device：
1st, resistance-strain chip pressure transducer due to need directly be connected with tension steel wire rope, if generation sleety weather,
Then aqueous vapor and rainwater are easy to cause sensor degradation and inefficacy by bindiny mechanism's entrance sensor internal, if there is thunderbolt thing
Part, thunder-strike current is easily directly conducted to sensor and the signal amplification component being attached thereto by steel wire rope, causes its inefficacy, produces
Raw fault.
2nd, resistance-strain chip pressure transducer is a kind of sensor being attached in certain metal structure, and metal structure is originally
Body can produce counteracting force to offset the active force in regulation range, if there is invader apart from this sensing station farthest
Pull steel wire rope, because the deformation of the frictional force on steel wire and steel wire is so that the active force being ultimately conducted on sensor is not enough
To produce deformation in resistance-strain chip pressure transducer, the change of the no signal of telecommunication then, it is allowed to produce wrong report.
3rd, resistance-strain chip pressure transducer is typically the small-range sensor between 10-200KG, if producing on steel wire rope
When having given birth to one and having exceeded the active force of maximum range that resistance-strain chip pressure transducer specifies, resistance-strain chip pressure
Metal structure on sensor will produce permanent deformation, once producing permanent deformation, sensor cannot accurately measure steel wire
Power on rope, then will produce false alarm phenomenon.
4th, because technological level limits, resistance-strain chip pressure transducer weak output signals, easily it is disturbed；Another due to
Being applied to outdoor environment resistance-strain chip pressure transducer more, can be effected by environmental factors, lead to its output signal to be produced
The certain error of life, causes wrong report.
To sum up, in existing tension fence alarm device application resistance-strain chip pressure transducer exist water proofing property poor,
Certainty of measurement is low, short life, the problems such as be easily subject to external environmental interference.
Content of the invention
For the shortcoming of above-mentioned prior art, the purpose of this utility model be provide a kind of good waterproof performance, certainty of measurement high,
Life-span length, and contactless relative parallel displacement alarm device easy for installation, that anti-tampering ability is strong, solve existing resistance-strain
The water proofing property that chip pressure transducer exists is poor, certainty of measurement is low, short life, easily by external environmental interference the problems such as.
To achieve these goals, this utility model provides a kind of relative parallel displacement alarm device, including：Sensor,
Line of pull, housing and be placed in the displaced block in housing and elastic component, described elastic component between displaced block and housing,
And it is fixedly connected on the two ends of housing, displaced block both sides are provided with the hole or post for line of pull riveting, and described line of pull is in institute's rheme
Pass from housing both sides after riveting firmly on the hole of shifting block both sides or post；Described sensor is placed in displaced block space above, its with
Displaced block is not directly contacted with；Specifically, line of pull, when being acted on by external tensile force, drives displaced block to move in parallel, sensor
The relative displacement signal of displaced block is detected, and be converted into electric signal output, send alarm.
Described housing corner convex erecting bed is provided with the first installing hole.
Described displaced block is provided with the second installing hole.
Described sensor is including but not limited to following several：Optical encoder sensor, gyro sensor, magnetic force sensing
Device, acceierometer sensor.
Described optical encoder sensor, including code-disc, described code-disc is the plate of certain length and width, if decile is carved with code-disc
Dry rectangular slits, described code-disc is additionally provided with threeth installing hole corresponding with the second installing hole.

Installing hole.
Described line of pull can be steel wire rope.
Compared with prior art, the sensor in this utility model relative parallel displacement alarm device, contactless, the life-span
Long, by non-contact detecting, it is to avoid the damage to sensor itself and measured object, even if in the harsh ring having water or oily splash
In border also can stable detection, response speed is fast, flexible for installation.Generally speaking, there is advantages below：
1st, steel wire rope is only connected with displaced block, and sensor no direct physical contact, and as gyro sensor, sensor
It is sealed in proof mechanism of water, therefore can prevent rainwater and aqueous vapor from causing to damage and losing efficacy.
2nd, displaced block is directly attached on steel wire rope, and displaced block does not produce active force, and also will not be according on steel wire rope
Active force and produce counteracting force, therefore displaced block can respond micro force on steel wire rope, will not produce damage.
3rd, displaced block does not have electronic device in itself, therefore is subject to such environmental effects very little, and sensor can be using numeral letter
Number process and technique for temperature compensation, comprehensively after it is reliable and stable and substantially do not affected by environmental change.
