Description
Technical field
The invention belongs to computer hardware field, be specifically related to a kind of computer monitor preventing divulging a secret based on fingerprint recognition.
Background technology
Existing computer monitor, its bearing carried generally only has the function regulating front and rear angles, and does not have the function regulating upper-lower height.But for the user of different height, the angle of its observation display is different.Placing height due to display is fixing, and the user making height higher usually needs the curved back of the body, bows and watch display attentively, and this easily causes user's neck, lumbar fatigue, diseases induced, is unfavorable for user health.
Existing computer monitor does not have recognition function, anyone can open or close display by the switch on display, prevents the department divulged a secret, when user leaves temporarily at some needs, Shutdown Hosts is pretty troublesome, and only closedown display is easily opened again and peeps.
Summary of the invention
The object of the invention is to provide a kind of computer monitor preventing divulging a secret based on fingerprint recognition, solves existing display and height and monitor switch cannot be regulated without the problem of recognition function.
Technical scheme of the present invention is: a kind of computer monitor preventing divulging a secret based on fingerprint recognition, comprise display unit main body and the jacking gear being arranged on display unit main body bottom, described jacking gear comprises base plate, be fixed on the sleeve on base plate, to be arranged in sleeve and to slide up and down with sleeve the screw rod coordinated, and the nut to coordinate with screw flight, the upper end of described screw rod is fixedly connected with the erection joint be arranged on display unit main body dorsal surface, plain thrust bearing is provided with between described nut and sleeve ends, the main circuit of display is provided with fingerprint recognition switch, described fingerprint recognition switch is made up of fingerprint recognition system and relay, relay is arranged on the main circuit loop of display, fingerprint recognition system is by fingerprint sensor, processor, storer, control output circuit is formed, processor respectively with fingerprint sensor, storer is connected with control output circuit, control output circuit to be connected with relay.
Further, fingerprint sensor is optical fingerprint sensor, semiconductor fingerprint sensor, ultrasonic scanning fingerprint sensor or radio frequency sensor.
The present invention compared with prior art tool has the following advantages:
Display adjustable-height of the present invention, meets the needs of the user of different health height, owing to being provided with fingerprint recognition switch, only having specific people just can open display, thus reaches the effect preventing from divulging a secret.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structured flowchart of fingerprint recognition switch of the present invention;
Fig. 3 is for controlling output circuit.
Embodiment
Embodiment
As shown in Figure 1, comprise display unit main body 1 and the jacking gear being arranged on display unit main body 1 bottom, described jacking gear comprises base plate 2, the sleeve 3 be fixed on base plate, be arranged in sleeve 3 and slide up and down the screw rod 4 that coordinates and the nut 5 with screw rod 4 threaded engagement with sleeve 3, the upper end of described screw rod 4 is fixedly connected with the erection joint 6 be arranged on display unit main body 1 dorsal surface, is provided with plain thrust bearing 7 between described nut 5 and sleeve 3 end.By jacking gear support displays main body 1, rotating nut 5 can be elevated display unit main body 1 easily, and with the use of satisfied different height user, eliminating user needs croucs to watch the problem of display attentively, is conducive to protection computer user healthy; Simultaneously because plain thrust bearing 7 can reduce the friction force between nut 5 and sleeve 3, therefore nut 5 rotates flexibly, and display unit main body 1 is highly easy to adjust.
As shown in Figure 2, the main circuit of display is provided with fingerprint recognition switch, described fingerprint recognition switch is made up of fingerprint recognition system and relay, relay is arranged on the main circuit loop of display, fingerprint recognition system is made up of fingerprint sensor, processor, storer, control output circuit, processor is connected with fingerprint sensor, storer and control output circuit respectively, controls output circuit and is connected with relay.Fingerprint sensor can select optical fingerprint sensor, semiconductor fingerprint sensor, ultrasonic scanning fingerprint sensor or radio frequency sensor.
Control output circuit as shown in Figure 3, when output switch parameter end PAO exports as high level, low level is become through rp-drive 7406, make lumination of light emitting diode, thus make photistor conducting, make transistor VT conducting simultaneously, just make the coil electricity of relay K, relay contact closure, makes alternating current 220V power supply connect.Otherwise when output switch parameter end PAO output low level, relay contact disconnects.In the drawings, resistance RL represents load, and the effect of diode VD is protective transistor VT.When relay K adhesive, diode VI) cut-off, do not affect the normal work of circuit.During relay release, due to the existence of relay coil inductance, thus store electric energy, at this moment transistor VT ends, so can produce higher induced voltage at coil two ends.The polarity of this voltage is under upper bearing. just, anode is being added on the collector of transistor VT.When induced voltage and Voc sum are greater than the collector reverse voltage of transistor VT, transistor VT will be breakdown and damaged.After adding diode VD, the induction current that relay coil produces is flow through by diode VD, and transistor VT is protected.
Preferably, be provided with first hole in the middle part of described base plate 2, the lower end of described sleeve 3 and first hole grafting coordinate, and socket connection makes sleeve 3 and base plate 2 split, and are convenient to separately transport and rapid-assembling.Described erection joint is provided with second hole, and the upper end of described screw rod 4 and second hole grafting coordinate, and socket connection enables screw rod 4 and erection joint split, and are also convenient to separately transport and rapid-assembling.Being provided with xsect in described sleeve 3 is square guide pole 8, be provided with in described screw rod 4 and slide up and down with guide pole 8 third hole coordinated, coordinated by guide pole 8 and third hole and moving up and down of screw rod 4 is led, when can avoid rotating nut 5, screw rod 4 rotates with nut 5, and lift adjustment is more convenient.Described first hole, second hole and third hole all can be the square hole of regular polygon hole or other shape.
The above embodiment only have expressed the embodiment of the application, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the application's protection domain.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from technical scheme design, can also make some distortion and improvement, these all belong to the protection domain of the application.
