Description
Technical field
The utility model relate to electronic equipment, particularly a kind of low-power consumption visual doorbell system schema with liquid crystal display.
Technical background
Along with the propelling of home intelligence and the raising of resident's security protection consciousness, household door bell and button system there occurs the change of essence.Door bell and button system in the past generally adopts traditional music door-bell, when guest visits, click doorbell button, doorbell sends music tip owner has people to visit, if the identity of owner needs to know visiting person, needs to be observed by opal or judged by partition door dialogue inquiry etc. and confirmed.If visiting person not within opal range of observation and the sound of owner to visiting person be unfamiliar with, so owner is just difficult to make judge accurately to the identity of visiting person, if at this moment rashly open the door will there is potential safety hazard.In order to effectively overcome the above problems, current door bell and button system starts the visual doorbell system adopting band liquid crystal display, when there being guest to visit, owner is when obtaining music tip, the identity of the image that can be photographed by the camera be arranged on the outdoors display person that effectively confirms visiting clearly on a liquid crystal display, is thoroughly eliminated safe hidden trouble.Under normal circumstances, in the visual doorbell system of this band liquid crystal display and camera, liquid crystal display, the first-class duty being always in energising of making a video recording, system was powered through Transformer Rectifier filtering afterwards with 220V alternating current usually, so not only bring the inconvenience of installing and using, and the long-time energising work such as liquid crystal display, camera also can affect their serviceable life.
If system carries a kind of control circuit, can realize only having when visitor press doorbell button, music tip sound equipment rise time, liquid crystal display, camera are just energized work, and after music tip sound terminates, the power supply of liquid crystal display, camera can be closed automatically, liquid crystal display, camera quit work, and this not only can reduce the overall power consumption of system greatly, and can extend the serviceable life of system.
Summary of the invention
The purpose of this utility model is exactly the visual doorbell system of inventing a kind of low-power consumption with liquid crystal display, reduces power consumption, saves the energy, extends system serviceable life.
In order to realize the purpose of this utility model, by realizing by the following technical solutions:
With a low-power consumption visual doorbell system for liquid crystal display, comprise power supply, control circuit, music door-bell, bell button, loudspeaker, electronic switch, camera and liquid crystal display, described power supply is connected with control circuit, music door-bell; Power supply is connected with camera, liquid crystal display by electronic switch; Bell button controls the operation of music door-bell; The signal that music door-bell runs is transported to control circuit; The control signal of control circuit is transported to electronic switch.
Especially, described power supply is low tension battery.
Especially, described electronic switch comprises NPN triode Q1, PNP type triode Q2, resistance R2, resistance R3, resistance R4 form; The emitter of Q2 is connected with the positive pole of power supply, positive source is connected to after the base stage of Q2 is connected with resistance R4, the collector of Q2 is connected with camera, liquid crystal display, the base stage of Q2 is connected through the collector of R3 and Q1, the emitter of Q1 is connected with power cathode, and the base stage of Q1 is connected to control circuit through R2.
Especially, described control circuit is by resistance R1, by polar capacitor C1, the detecting circuit that is made up of polar capacitor C2, diode D1, diode D2; The positive pole of C1 is connected with music door-bell with loudspeaker, and the negative pole of C1 is connected with the negative pole of the positive pole of D2, D1, and the positive pole of D1 is connected with power cathode, and the negative pole of D2 is connected with electronic switch, and the positive pole of C2 is connected with the negative pole of D2, and the negative pole of C2 is connected with power cathode; R1 and C2 is in parallel, and one end is connected with the negative pole of D2, and the other end is connected with power cathode.
The beneficial effects of the utility model are: the present invention can reduce the overall power consumption of system greatly, save the energy, and can extend the serviceable life of system.
Accompanying drawing illustrates:
Fig. 1 is functional block diagram of the present invention.
Fig. 2 is circuit control principle figure of the present invention.
Embodiment
Below in conjunction with Fig. 1, Fig. 2, be illustrated embodiment of the present utility model, the utility model is not limited to following this embodiment.
Connect according to the mode in the circuit theory diagrams of Fig. 2, the direct supply of power acquisition 6V.Click doorbell button 5, music door-bell 3 meeting output sound music signal is to loudspeaker 4, and remind owner to have people to visit, this music signal can continue for some time.Meanwhile, voltage can be produced at A point after the detecting circuit detection that this music signal forms via C1, D1, D2, C2 and R1.This voltage makes the electronic switch be made up of R2, R3, R4, Q1 and Q2 open, 6V direct supply starts to power to camera 7 and liquid crystal display 8, camera 7 and liquid crystal display 8 normally work, and now owner just can according to the identity of the person that judges visiting exactly of the vision signal in liquid crystal display 8.
After music signal terminates, A point voltage also disappears thereupon, and the electronic switch be made up of R2, R3, R4, Q1 and Q2 disconnects, and 6V direct supply stops powering to camera 7 and liquid crystal display 8, and whole system is just in Micro Energy Lose state.Visible in this visual door bell and button system, because camera 7 and liquid crystal display 8 only just work when music is sounded, all be in off-position at ordinary times, so the overall power consumption of whole system is just very little, direct battery power can be used, without the need to using 220V alternating current to power afterwards through Transformer Rectifier filtering, use very convenient, and extend the serviceable life of system.
