Abstract
The utility model discloses a anti-drop hard disk camera, which comprises a hard disk, a vibration displacement sensor and a relay. A DC power Vi is outputted to a portable hard drive through a relayJ, the relay J is controlled by a vibration displacement sensor SC-1, wherein the DC power Vi is applied to the 5 pin of SC-1 through a manual switch K, the 4 pin of SC-1 is grounded through a capacitor C, the controlled output 3 pin of SC-1 is connected to the base pole of the transistor BG through a potentiometer W, the emission pole of the transistor BG is grounded, and the collector pole of the transistor BG is connected to the control pin of the relay J. After it is predicted that a collision is likely to occur, the power supply is immediately shut down, and magnetic heads are moved to the stop region for protection of the hard drive, so that circuit hardware is protected from being broken, and the hard drive is prevented from fatal damage. The camera is simple in circuit design, andis completed by adding simple circuits in the power circuit of hard disk camera in prior art, thus has definite popularization and application value.
Description
Technical field
The utility model relates to a kind of video camera hard disk protection circuit, specifically, relates to a kind of video camera hard disk shatter-resistant protective circuit.
Background technology
Along with development of electronic technology, the video camera of band hard disk uses more and more general, because it is light small and exquisite, and the liking of users that be subjected to deeply easy to use and carry.But it is in use, often because energy too concentrates on shooting, and very easy fall unexpectedly or strenuous vibration causes the video camera hard disc data to lose or circuit board damage.In order to improve the shockproof shatter-resistant performance of video camera, we need change the protection of video camera is become active mode by the passive mode in past.Predict might clash into after, close camera power supply in time, and with magnetic head move to stop the district with the protection hard disk, can avoid hard disk to suffer fatal infringement.
The utility model content
A kind of shatter-resistant hard disk video camera that the utility model designs in order to solve the problems of the technologies described above just.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of shatter-resistant hard disk video camera comprises hard disk, vibration displacement transducer and relay; Its DC power supply Vi exports to portable hard drive by relay J, relay J is controlled by vibration displacement transducer SC-1, wherein DC power supply Vi is added to 5 pin of SC-1 by hand switch K, 4 pin of SC-1 link to each other with ground by capacitor C, the control of SC-1 is exported 3 pin and is linked to each other with the base stage of triode BG by potentiometer W, the emitter of triode BG links to each other with ground, and the collector electrode of triode BG links to each other with the control pin of relay J.
Described a kind of shatter-resistant hard disk video camera, its capacitor C is 10uF, and potentiometer W is 100K Ω, and triode BG is an amplifier tube 8050.
SC-1 omnidirectional vibrating sensor is a kind of omnirange solid-state controller spare that integrates vibration and displacement measurement, it adopts most advanced solid-state acceleration detection device, both vibration was had very high detection sensitivity, the voice signal to surrounding environment suppresses again, has very strong antijamming capability.Because video camera often is to use in moving, for misoperation in the normal use, electronic switch K has been installed on video camera, be used to close or use the shatter-resistant function.Used potentiometer W in addition on the panel, can regulate vibration detection sensitivity, reduced the probability that misoperation appears in the use of hard disk camera according to user's custom.
The beneficial effects of the utility model are: the protection of hard disk camera becomes active mode by the passive mode in past; predict might clash into after; close power supply in time; and with hard disc magnetic head move to stop the district with the protection hard disk; both can protect hardware circuit to damage, and can also avoid hard disk to suffer fatal infringement.This circuit design is simple, increases ball bearing made using and get final product in original hard disk camera power circuit, and its realization is very convenient, has certain application value.
Description of drawings
Fig. 1 is a kind of shatter-resistant hard disk of the utility model camera circuitry schematic diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of shatter-resistant hard disk of the utility model video camera comprises hard disk, vibration displacement transducer and relay; Its DC power supply Vi exports to portable hard drive by relay J, relay J is controlled by vibration displacement transducer SC-1, wherein DC power supply Vi is added to 5 pin of SC-1 by hand switch K, 4 pin of SC-1 link to each other with ground by capacitor C, the control of SC-1 is exported 3 pin and is linked to each other with the base stage of triode BG by potentiometer W, the emitter of triode BG links to each other with ground, and the collector electrode of triode BG links to each other with the control pin of relay J.
Described a kind of shatter-resistant hard disk video camera, its capacitor C is 10uF, and potentiometer W is 100K Ω, and triode BG is an amplifier tube 8050.Capacitor C is the time-delay control capacitance, and value is big more, and time-delay is just long more, otherwise otherwise then.Potentiometer W is that potentiometer is set in external sensitivity, regulates its sensitivity by adjusting potentiometer W resistance.
The utility model is not limited to above-mentioned preferred forms, and other any identical with the utility model or akin products that anyone draws under enlightenment of the present utility model all drop within the protection range of the present utility model.
