Abstract
The utility model discloses a photoelectric anti-theft alarm which belongs to the technical field of the photoelectric automatic control. A luminous tube, a photosensitive tube, and an optical system are formed into a photoelectric sensing system. The alarm provided with the luminous tube and the photosensitive tube is arranged at the back side of the door. The optical system is arranged on a door frame corresponding to the alarm. Comparators F1 and F2, a triode, and a relay are formed into a comparative control system. The signal comparator F1 outputs the alarm signal, and a signal switch K1 is closed through the triode and the relay. One path of the alarm signal is input an alarm generating system, and the other path of the alarm signal is input a time control comparator F2 to control the alarm time. The inner part of a door lock is provided with a switch K0 which is controlled by a key and a lock safety. The utility model is suitable for the theft protection alarm for the house door.
Description
The utility model relates to photoelectricity automatic control technology field, and specifically describing is a kind of photoelectricity burglar alarm.
The existing in the market alarm of selling mainly utilizes the pyroelectricity principle, this series products weak point, and the rate of false alarm height is not debated other ability, cost price height to owner.
The purpose of this utility model is, adopts advanced photoelectric technology, and owner enters the chamber and can not report to the police, and has only when thief's sled is stolen just to sound the alarm, and can stop newspaper automatically after warning.
The utility model is achieved in that it forms owner by power supply, electric switch and door lock and set system, photoelectric sensor system, comparison control system and warning generation systems and form.
Photoelectric sensor system is made up of the optical system that is contained in luminotron, the photosensitive tube in the alarm and be contained on the doorframe, alarm is contained in behind the door, optical system be contained in and the corresponding doorframe of reporting to the police on, when door is shut, the optical system that is contained on the doorframe all absorbs the light of luminotron, and when door is prized, the trend of prying open is to a certain degree the time, optical system reflexes to photosensitive tube with luminotron part light, makes the photosensitive tube output alarm signal.
Relatively control system (3) is by comparer (F
1, F
2), triode (D
3) and relay (J) composition, signal comparator (F
1) output alarm signal is through triode (D
3) and relay (J), make signaling switch (K
1) close alerting signal one tunnel input warning generation systems (4), one tunnel input time control comparer (F
2), time control comparer (F
2) output termination triode (D
3) base stage, the control time of fire alarming.
The power supply electric switch K that is subjected to key and lock insurance control is housed in the door lock
0, turning the key in the lock, control device will be with electric switch K
0Disconnect, go out and lock a door or will lock insurance inside, electric switch K
0Be switched on again, successfully realized the function that owner enters and do not report to the police.
Good effect of the present utility model is, in case door is prized, will send chimes of doom in the process of forcing open the door, and stops newspaper automatically after sending chimes of doom number minute, and the owner who holds key is had recognition function, and owner enters and do not report to the police.Double horn is housed reports to the police, warning gives great volume.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model basic circuit diagram;
Fig. 2 is that the utility model light path is transmitted synoptic diagram;
Fig. 3 is the schematic appearance of the utility model alarm.
As shown in Figure 1, the used power supply of the utility model is a DC-AC two-use, power supply electric switch K
0Be contained in the door lock, by key or its connecting and disconnecting of lock insurance control.Turn the key in the lock electric switch K
0Disconnect, go out and lock a door or will lock insurance inside, electric switch K
0Connect.Light emitting diode D
1With phototriode D
2Be contained in the alarm light emitting diode D
1Send light, by phototriode D
2Receive.This alarm is contained in behind the door at ordinary times, when door is shut, is contained in optical system 5 on the doorframe with light emitting diode D
1Light all absorbs, and is prized when door, and during the trend that has out, optical system 5 is with light emitting diode D
1Part light reflexes to phototriode D
2, after accurately adjusting, when making a quilt prize to a certain degree, phototriode D
2The light that receives is enough to make its output voltage to be higher than the benchmark comparative voltage, makes triode D
3Conducting, relay work, control warning circuit contact K
1Connect, chimes of doom is sent in audio-frequency generator work.Guarantee to send warning in by the sled process at door.Power supply passes through R during warning
10To C
3C is worked as in charging
3Terminal voltage is higher than F
2During positive terminal voltage, F
2Output low level is because at this moment door is still closing F
1Also export low voltage level, thereby relay J is discharged, warning stops.Guarantee after reporting to the police several minutes, initiatively to stop newspaper.
May in system, take following measure: big capacitor C is set because some interference or noise cause false alarm in order to solve
1And C
2, solve owing to disturb the false alarm that causes; Capacitor C
3Negative terminal earth-free but be connected on R
6And R
7The junction, under normal circumstances, make F
2Thereby positive input terminal have a positive bias voltage to eliminate the influence of various noises and interference; F
1, F
2The benchmark magnitude of voltage higherly also fixed, thereby various undesired signal can not make F
1And F
2Upset.
