Description

Combined early warning type far infrared electronics fence

The utility model belongs to microelectronics technology, particularly a kind of combined early warning type far infrared electronics fence that is used for warning device.

Existing infrared warning device all is simple infrared thermal release electric induction mode, no matter be direct-injection type or reflective, problem of ubiquity, only be fit to be applied to unmanned zones of action such as bank, finance, it is indoor to be not suitable for being applied to private residence, can't work in that the situation that the people is arranged is next, whether trespass because be difficult to distinguish.

The purpose of this utility model is to provide a kind of combined early warning type far infrared electronics fence that private residence is used that is suitable for.

The utility model is by pyroelectric infrared sensor, and infrared rays transmitting terminal and infrared rays receiving terminal three parts constitute.Pyroelectric infrared sensor early warning switch should adopt dual-element to form according to from different places, and design has the detecting head of gain adjusting circuit.The infrared rays transmitting terminal is made of transmitting terminal tubular body and emission electronic circuit; The infrared rays receiving terminal is made of receiving terminal tubular body and reception electronic circuit.

Further narrate content of the present utility model below in conjunction with drawings and Examples.

Fig. 1 is an overall structure schematic diagram of the present utility model,

Fig. 2 is the utility model transmitting terminal electronic circuitry,

Fig. 3 is the utility model receiving terminal electronic circuitry.

Among the figure: 1 infrared rays transmitting terminal, 2 infrared rays receiving terminals, 3 pyroelectric infrared sensors, 4 bodies of wall, 5 alarm main frames.

Infrared emitting end 1 is the tubular body that has some holes at inwall with Baltimore groove, tube wall The inside studs with the electron emission circuit board, and the electron emission circuit board is generally 3～8, the electricity on several plates Electronic circuit is identical, and is in parallel between plate and the plate. Infrared receiving terminal 2 also is with Baltimore groove, pipe at inwall The tubular body the inside that has some holes on the wall studs with the reception electronic circuit board, receives electronic circuit board one As also be 3～8, the electronic circuit on several plates is identical, and is in parallel between plate and the plate. Inside is equipped with The infrared emission end tubular body of electronic circuit and the tubular body of infrared receiving terminal are separately fixed at the window both sides Body of wall 4 on, pyroelectric infrared sensor 3 is fixed on appropriate location above the window. Use lead Respectively transmitting terminal, receiving terminal, pyroelectric infrared sensor are linked to each other with the warning system main frame, namely consisted of Combined early warning type Far infrared electronic railings of the present utility model.

The transmitting terminal electronic circuit as shown in Figure 2, by astatic multivibrator, triode and infrared emission Head consists of. " 555 " time-base integrated circuit A₁Consisted of astatic multivibrator with peripheral cell, its frequency is 30KHz, under the Continuity signal effect that main frame transmits, by A₁The burst pulse square-wave signal of (3) pin output is through triode VT₁Do to promote remote light collecting emitting head TLN911 after electric current amplifies Inner infraluminescence pipe outwards penetrates and is approximately parallel infrared pulse light beam, and this circuit is with corresponding Receiving circuit matches, and effective range is greater than 13m. With in parallel of top circuit, make multiple spot and arrange Emitting head.

The receiving terminal electronic circuit as shown in Figure 3, by infrared receiving terminal, triode VT₂、VT ₃With amplification circuit A₂Form. The 30KHz infrared pulse light that the radiating portion of correspondence is sent here is by adopting With the TLP911 infrared receiving terminal reception of convex lens designs, and convert to corresponding by inner photosensitive tube The signal of telecommunication, this signal is through C₅Be coupled to VT₂Carry out preposition put in advance after, pass through C₆Be coupled to A₂(1) pin is by A₂Amplify inside, shaping, and band is relatively logical, makes its (7) pin output low level, and then makes VT₃, VS all is in cut-off state, in case infrared beam is blocked A then by people or thing₂Output of pulse signal is arranged, and this signal is through triode VT₃Hyblid Buffer Amplifier, C₁₀And VD₄、VD ₅Behind the voltage multiplying rectifier, melt a VS and lead Logical, send alarm command to alarm host machine.

When using the utility model, the pyroelectric infrared sensor of this far infrared electronics fence is converted into ultra-weak electronic signal after having received the infrared radiation that sends in the target, after amplification is handled through electronic circuit, passes to alarm host machine.

Some characteristic of microwave that the utility model utilizes the electromagnetic spectrum mid and far infrared to have, as: penetration power is strong; Can modulate etc., create that multiple spot arranges, alarm region can be formed sightless fence together, as long as nobody passes through, electronic circuit does not produce pulse voltage signal, just alarm signal does not take place, stops wrong report.Connect a wide-angle pyroelectric sensing switch, near taking precautions against the zone, the pyroelectric sensing device at first moves as the people, and signal is passed to the far infrared electronics fence of connection, and the warning fence starts.As the signal detection function end of warning system, extremely be applicable to the anti-theft burglary-resisting system of residential houses, cities and towns.Solve in the current civilian burglar alarm technology application, ubiquitous error warning problem is gone back safety in the common people, and then the iron bar of cancellation resident building installation.

Effective control distance of the present utility model is greater than 13 meters.
