Description

A kind of anti-theft method that adopts rotating bars

Technical field

A kind of theft preventing method, especially a kind of theft preventing method that adopts rotating bars.

Background technology

At present at personnel's discrepancy place such as door, window or money, the antitheft infrared ray anti-theft method that adopts often of thing bin,, often cover light beam or received by photoreceptor and cause false alarm as infrared radiation source because of some moving objects such as mouse though this method can be effectively antitheft.Especially some banks and other financial department are normal because false alarm brings many doubts, dispersion people energy, and therefore how improving the warning accuracy is the problem that anti-theft technique needs to be resolved hurrily.

Summary of the invention

The objective of the invention is: the anti-theft technique of releasing a kind of difficult wrong report.

The object of the present invention is achieved like this: it comprises motor, motor driving member, alarm and supply unit, is connected with rotating bars on the described motor driving member, it is characterized in that: string has the overload warning circuit in the working current loop of described motor.

Like this, when the robber desires access door, window or wants to open the bin lock, horizontal is the rotating bars on the motor driving member of being connected in of running by the motor band in their front, these rotating bars just like a rule road blocking tiger, the burglar is difficult to go beyond, as long as any one position of health of robber touches these rotating bars, will the motor momentary load with the rotating bars running be increased, at this moment motor operations current in loop surge, the overload warning circuit just will trigger sounding alarm and report to the police.Owner hears that chimes of doom promptly can be in time to police report, and general robber hears that chimes of doom also can end crime and escape to follow.If the robber wants to destroy behind the motor driving member in the inlet chamber, then in to the driving member destructive process that burns the wind, also will increase motor load, also can make alarm equipment alarm; If the robber wants also to be not easy from outdoor motor power is cut off, the one, because power lead is in the behind of rotating bars, must run into rotating bars, some important departments can also be made the work power supply with rechargeable battery, outdoor outage, motor rotates in the same old way.And when animals such as mouse during near the rotating bars of rapid movement, their antenna will at first touch strand, and they can feel dangerous and select other road walking can not have no sensation as running into infrared light, pass through back and forth in the same old way and cause false alarm.Because driving member and rotating bars that motor drives are all very light and handy, the load on the motor drive shaft is very little, so power consumption is little during the motor rotation, and sound is also very light, and can not have a rest to the people exert an influence.

Embodiment

Among Fig. 11 is the wall outside, the 2nd, window, the 3rd, motor, the 4th, as the axle sleeve of motor driving member, the 5th, long filament type rotating bars, the 6th, be inserted in transformation and stable-pressure device in the socket, it belongs to the part of supply unit, the 7th, the output lead of supply unit, the 8th, hang electrical box on the wall, the 9th, the timing engage relay circuit in the electrical box, it belongs to another part of supply unit, the 10th, the sounding alarm circuit in the electrical box, the 11st, the overload warning circuit in the electrical box, the 12nd, motor wire, the 13rd, as the screw of connector, the 14th, the window stalk in the middle of the window, the 15th, move window, the 16th, window frame.

Described screw 13 tacks motor 3 and is being on the middle window stalk 14 of window, on the axle of motor axle sleeve 4 is housed, be fixed with rotating bars 5 on the axle sleeve, rotating bars is the long filament type among the figure, two up and down, therefore anyone will enter in the window from the rotating bars of window rotation, just must contact long filament type rotating bars 5.In the wall plug transformation and stable-pressure device 6, voltage output lead 7 is arranged below, it is incorporated into working current in the electrical box 8, and regularly engage relay circuit 9, sounding alarm circuit 10, overload warning circuit 11 are being set in the electrical box from top to bottom, and they are electrically connected mutually.Motor wire 12 is connected between motor and the overload warning circuit.Mobile window 16 among the figure can move in window frame 15, if do not need daytime when antitheft, scalable is engage relay circuit 9 regularly, because relay is being controlled power supply, therefore do not powered its daytime to motor, the automatic energized of circuit 9 meetings when need are antitheft to evening, motor, overload warning circuit and sounding alarm be work just.When daytime, motor did not change, because two long filament type rotating bars point-blank, therefore during the motor stall, two rotating bars can be as state among the figure, and motor is very little again, when therefore outwards seeing in window at ordinary times, motor and rotating bars are all blocked by the stalk of the window in the middle of the window 14, do not influence window vision and daily housework.The window stalk can be fixed, and also can be the limit that a fan moves window frame.

The motor driving member also can be belt pulley, the sprocket wheel that is driven by axle except axle sleeve, and with belt or chain, barrier sheet can be located on belt or the chain, also can be located at by belt or chain with follower on, the robber meets these barrier sheets equally also will make motor load increase, report to the police thereby cause, can increase motor load but do like this, sound is also bigger in the running.

Fig. 2 is a circuit interconnect pattern of the present invention.E1 among the figure, E2 are two groups of stabilized voltage supplys exporting in the transformations of 6 expressions from Fig. 1 and the stable-pressure device, H be have about the time timing circuit of two output terminals, two relays about P1, P2 timing circuit, P1K and P2K are respectively Second Mate's normally opened contacts of P1, P2 relay, and above-mentioned H, P1, P2, P1K, P2K form regularly engage relay circuit.J among the figure is alert sound pronunciation vibration integrated package, and Y is the output loudspeaker that connect integrated package J, and above-mentioned J, Y form the sounding alarm circuit.G is a triode, and R is the base resistance of triode G, and L1, L2 form one pair of mutual inductor, and C is an electric capacity, and D is a diode, and above-mentioned triode G, resistance R, coil L1, L2, diode D and capacitor C are formed the overload warning circuit.Z is a motor.

When time timing circuit H arrives setting-up time, the output line that order is connected on the H left side has voltage output earlier than the output line on the right, so relay P1 elder generation adhesive, the relay P2 that is connected on the right delays adhesive than P1, therefore normally opened contact P1K is than the first adhesive of P2K, and the induction current in the time of making the motor initiating like this in coil L2 can not influence the operate as normal of overload warning circuit.When touching rotating bars 5 among Fig. 1 if any the robber, because motor is subjected to resistance, therefore the electric current that flows through motor increases, the electric current that flows through mutual inductor coil L1 also increases, so just induce stronger electromotive force among the L2, the electric current that electromotive force produces enters into the base stage of triode G through diode D, and the relay P3 of string in triode G collector loop gets, so the normally opened contact P3K-1 of P3 and P3K-2 adhesive cause relay P3 self-locking.Meanwhile, the sounding alarm circuit gets electric through the P3K-2 contact, and alert sound pronunciation vibration integrated package J work makes the loudspeaker Y that is connected on chip output send alert sound.C designs in order to filter out normal alternating current, and R1 is the working point levelling resistance of triode.Warning circuit can also utilize P3K-2 contacting phone or mobile phone except adopting sounding alarm, report to the police to the owner at a distance or the police.The releasing of reporting to the police can be pulled out power supply, also can adopt switch form.Also available controllable silicon of relay among the figure or steady-state circuit.

During form in adopting Fig. 1,, and establish yarn, can prevent effectively that also insects such as mosquitos and flies from invading indoor at the window angle if motor rotary speed is very fast.Can also make the electric wave of mosquito repellent on the metal rotation band or rat destruction as rotating bars during for metal, reach the function of one-object-many-purposes.
