Abstract
The invention provides a warning device for a security door at a non-tight closing state. The warning device is composed of the security door, a handle magnetostriction displacement (liquid) sensor, a doorframe magnetostriction displacement (liquid) sensor and a doorframe.
Description
Affiliated technical field
The present invention relates to a kind of alarm technique field, especially a kind of antitheft door closes the Men Buyan warning device.
Background technology
Along with progress and the development of times of society, city life rhythm of life is constantly accelerated, and thing valuable in the family is also more and more, and anxious the going out of people do not fastened if having time, special the elderly, and the chance of thief's crime is also more and more.
Summary of the invention
Do not fasten the stolen shortcoming of thing in order to overcome the people gate of going out hastily, a kind of easy for installation, cheap theftproof performance novel anti-theft door alarm device preferably is provided.
The present invention solves the technical scheme that its technical matters takes: at antitheft door and two Magnetic Induction devices of doorframe edge peace, when antitheft door will be reported to the police automatically near the time, till shutting.
The invention has the beneficial effects as follows prevents from going out forgets door to fastening the stolen phenomenon of thing.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the synoptic diagram of the warning device of antitheft door installation
1. antitheft doors, 2. handle magnetostrictive displacement (liquid level) sensors, 3. doorframe magnetostrictive displacement (liquid level) sensors, 4. doorframes among the figure
Embodiment
This device by: antitheft door 1, handle magnetostrictive displacement (liquid level) sensor 2, doorframe magnetostrictive displacement (liquid level) sensor 3, doorframe 4 are formed, the time of going out is shut antitheft door 1, handle magnetostrictive displacement (liquid level) sensor 2 is responded to doorframe magnetostrictive displacement (liquid level) sensor 3 is close mutually, meeting continuous alarm three times is up to fastening.
Magnetostrictive displacement (liquid level) sensor utilizes magnetostriction principle, comes measuring position exactly by strain-pulse signal of the crossing generation of two different magnetic fields.Measuring sensor is a waveguide, and the sensitive element in the waveguide is made by special magnetostriction materials.Measuring process is to produce current impulse in the electronic room by sensor, this current impulse is transmitted in waveguide, thereby outside waveguide, produce a circumference magnetic field, when this magnetic field be enclosed within on the waveguide magnetic field that the movable magnet ring as change in location produces when intersecting, because magnetostrictive effect, can produce a strain mechanical wave pulse signal in the waveguide, this strain mechanical wave pulse signal is with fixing speed of sound transmission, and detected by electronic room very soon.
Because transmission time and the movable magnet ring of this strain mechanical wave pulse signal in waveguide is directly proportional with distance between the electronic room, by Measuring Time, just can highly precisely determine this distance.Because output signal is a real absolute value, rather than signal ratio or that amplification is handled, so there is not the situation of signal drift or variate, more need not regularly heavily to mark.
Claims (3)
1. an antitheft door closes the Men Buyan warning device, it is characterized in that: it is made up of antitheft door, handle magnetostrictive displacement (liquid level) sensor, doorframe magnetostrictive displacement (liquid level) sensor, doorframe.
2. a kind of antitheft door according to claim 1 closes the Men Buyan warning device, it is characterized in that: magnetostrictive displacement (liquid level) sensor, utilize magnetostriction principle, come measuring position exactly by strain-pulse signal of the crossing generation of two different magnetic fields.
3. a kind of antitheft door according to claim 1 closes the Men Buyan warning device, it is characterized in that: employing be that two magnetostrictive displacements (liquid level) sensor interacts.
