Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and example.
As shown in Figure 1, be modulation reflective optic gate control system one-piece construction synoptic diagram.It comprises: lock body 1, key 2.Wherein lock body 1 comprises: lockable mechanism action motor 11, signal processing circuit 12, system power supply 13, light source transceiver module 14, lock body power supply outlet 15 and lock body end optical window 16; Key 2 comprises: key end optical window 21, key-powered inlet 22, reflecting surface 23, piezoelectric device 24, driving circuit 25 and identification code storage and output module 26.
Three kinds of implementations of light source transceiver module such as Fig. 2, Fig. 3, shown in Figure 4.With Fig. 2 is that example is illustrated, and comprises light source 1411 and photodetector 1412.Light source 1411 is the laser or the light emitting diode of any wavelength, the light that photodetector 1412 energy detection light source 1411 are sent.We only are the principle of work that example illustrates modulation reflective optic gate control system with the infrarede emitting diode.Because light source 1411 adopted infrarede emitting diode, our infrared light of also adopting supporting infrared receiving tube to come detection light source 1411 to send of photodetector 1412.In order to strengthen reception, can adopt Fig. 3, scheme shown in Figure 4.
Lock body end optical window 16 and the light transmission higher material of key end optical window 21 for light source 1411 is sent, if light source 1411 has adopted infrarede emitting diode, lock body end optical window 15 and key end optical window 21 can use black or wine-colored acrylic material.
Reflecting surface 23 is the reflecting surface that the light that light source 1411 sends is had the material of better reflectivity, if light source 1411 has adopted infrarede emitting diode, reflecting surface uses copper reflecting surface, silver-plated reflecting surface, the reflecting surface of aluminizing, gold-plated reflecting surface etc.
An object lesson of signal processing circuit 12 comprises motor-drive circuit 121 as shown in Figure 5, one-chip computer module 122, bandwidth-limited circuit 123, detecting circuit 124, shaping circuit 125.
An object lesson of driving circuit 25 comprises that amplifying circuit 251 and ultrasonic signal produce circuit 252 as shown in Figure 6.
The ultimate principle of the present invention's utilization: system power supply 13 can not only give signal processing circuit 12 power supplies, also matches to key 2 power supplies by lock body power supply outlet 15 and key-powered inlet 22.The infrared light that light source 1411 sends in the light source transceiver module 14 by lock body end optical window 16, key end optical window 21 after reflecting surface 23 reflection backs received by the photodetector in the light source transceiver module 13 1412.The ultrasonic signal that ultrasonic signal produces circuit 252 generations amplifies rear drive piezoelectric devices 24 through amplifying circuit 251, and drive reflecting surface 23 and have concavo-convex deformation displacement the time before and after occurring, the reflected light signal intensity that causes photodetector 1312 to receive changes.Ultrasonic signal is identified the sign indicating number storage and loads the digital signal modulation with output module 26, when digital signal is 1, piezoelectric device 24 will drive reflecting surface 23 occur with identical frequency before and after displacement the time and have concavo-convex deformation, the reflected light signal intensity that causes photodetector 1412 to be received changes; When digital signal was 0, piezoelectric device 24 was not worked and piezoelectric device 24 closely-coupled reflectings surface are positioned at same position, and photodetector 1412 receives the direct current reflected light signal.Photodetector 1412 receives intensity and outputs to bandwidth-limited circuit 123 through the reflected light signal of ovennodulation after opto-electronic conversion and carry out filtering, after removing noise signal, deliver to detecting circuit 124 detections, signal after the detection is by shaping circuit 125 shapings, deliver to one-chip computer module 122 and obtain information of identification code, and compare with the identification code of storage inside, when consistent, send instruction and drive lockable mechanisms action motors 11 by motor-drive circuit 121 and open door lock.
