Abstract
The utility model discloses a lockset with alarming functions ands lock core is provided with an infrared beam launching head and receiving head. The square-ware signals are generated through a phase-locked loop frequency discriminator and pass through an integration circuit and a drive circuit and then are sent by the launching head. The infrared beam receiving head receives the reflected signals and then amplifies and inputs them into a calculagraph through wave filtering to compare them with the standard signals with generating alarming triggering signals to make a trigger gear to generate the alarming action. This infrared beam launching and receiving device which mounts a human body inductor on the lockset can also make the microwave and ultrasonic wave technology realized. The lockset with alarming functions can be assembled and commissioned simply, has a strong capacity of resisting disturbance, has a high reliability, can alarm in advance and greatly reinforces the safety of the human body and the properties.
Description
Affiliated technical field
The utility model relates to a kind of improvement of lock, and it can apply on the various locksets.
Technical background
Though society is in continuous progress; the technology of lock is also constantly being improved; but antitheft problem remains a difficult problem of pendulum in people's life; how to guarantee that the safety that people live has become question of common concern; therefore; the scheme that often has the people that correlation technique is made improvements; for example Chinese patent CN200310108152.5 number about proposing a kind of mechanical lock in " machinery wireless electronic lock " in conjunction with electronic installation; as network wireless; mobile phone wireless; IC-card is wireless; infrared and radios etc. constitute the machinery wireless electronic lock; it also has the protective device of wireless electron warning device and lock; safety correspondingly improves; but trivial operations, the warning effect is still waiting further improvement.
Summary of the invention
Task of the present utility model is that a kind of lockset with alarm function will be provided, and it has tangible security protection effect, flexible movements, and alarm is timely, and antijamming capability is strong, can accomplish to frighten the malfeasant generation of resistance, protects the person and property safety better.
This practical institute type is to finish in such a way, this lockset with alarm function increases by two mechanical holes on lock core, infrared emission tube is installed in one of them mechanical hole, another installs infrared receiver tube, when in the certain distance of lock core the place ahead shelter being arranged, the infrared rays of infrared emission tube emission specific wavelength can be reflected by object, received and by amplifying by receiving tube, filtering, carry out frequency discrimination and output signal by frequency discriminator, by output signal is carried out timing, after surpassing the time of setting, circuit in the lockset can be alarmed to drive acoustic scene by output drive signal, other linkage such as language module, so when the people stays for a long time before lock or attempts to open lock, lock promptly produces alarm after can reaching the regular hour by reflection type infrared detection and by timing, to obtain the purpose of pre-alarm, strengthens the safety of the person and property greatly.This human inductor also can use technology such as microwave, ultrasonic wave accomplished.
Description of drawings
Below in conjunction with accompanying drawing to the utility model further instruction
Fig. 1 is a lockset lock core elevation of the present utility model.
Fig. 2 is a lockset infra-red detection circuit block diagram of the present utility model.
Among the figure 1, lock core, 2, the key hole, 3, the infrared rays emitting head, 4, infrared receiving terminal, 5, phase-locked loop frequency demodulator, 6, the vibration square-wave signal, 7, integrating circuit, 8, drive circuit, 9, infrared emission tube, 10, infrared receiver tube, 11, active high-pass filter, 12, fixed gain amplifier, 13, adjustable gain limiting amplifier, 14, timer, 15, adjustable timer reference generator, 16, flip flop equipment.
The specific embodiment
As can be seen from Figure 1, there is a keyhole (2) on this lock core (1) surface with lockset of alarm function, also there are two holes the upper end surface, a hole is infrared rays emitting head (3), another hole is infrared receiving terminal (4), it can produce reflex when shelter stops the infrared rays that infrared rays emitting head (3) emits, and infrared receiving terminal (4) will receive the signal that reflects, and this infrared rays that human inductor is installed on lockset transmits and receives device and also can use microwave, ultrasonic technology accomplished.
In Fig. 2, phase-locked loop frequency demodulator (5) output and vibration square-wave signal (6), integrating circuit (7), driving electrical equipment (8) is connected with infrared emission tube (9), and infrared receiver tube (10) is connected with source high-pass filter (11) in turn, enter the detection input of phase-locked loop frequency demodulator (5) behind fixed gain amplifier (12) and the adjustable gain limiting amplifier (13), another output of phase-locked loop frequency demodulator (5) links to each other with timer (14), another input of timer (14) connects adjustable timing reference generator (15), and its output then is connected with flip flop equipments (16) such as acoustic scene alarms.After the self-oscillation square-wave signal (6) of phase-locked loop frequency demodulator (5) improves the integrating circuit (7) and drive circuit (8) of infrared ray emission effciency through conduct, promoting infrared emission tube (9) sends and the corresponding to infrared light of phaselocked loop frequency of oscillation, when there is shelter in lockset the place ahead, infrared light is reflected, infrared receiver tube (10) receives infrared signal, through active high-pass filter (11) filtering, the amplification of fixed gain amplifier (12) amplification and adjustable gain limiting amplifier (13), detection input input from phase-locked loop frequency demodulator (5), phase-locked loop frequency demodulator (5) receive with the corresponding to input signal of its frequency of oscillation after, output signal to timer (14), when the timing length of timer (14) equates with the time span of setting in the adjustable timing reference generator (15), produce an alarm triggered signal, produce action to promote flip flop equipments (16) such as acoustic scene alarm.Under normal circumstances, lockset the place ahead does not have shelter, infrared light can not produce reflection, can not receive and the corresponding to infrared light of phaselocked loop frequency of oscillation, does not produce the alarm action, in addition in certain frequency band, phase-locked loop frequency demodulator (5) is only to producing response with the approaching signal of himself frequency of oscillation, and can not produce response to other interfering signal, so this lockset has stronger Recombinant Interferon ability, reliability is higher, installs, debugs all fairly simple.This technology not only can be used in the exploitation of novel lockset, also can change lock core by old lockset, realizes the alarm function of lockset.
Claims (2)
