The remote controller uses a semiconductor laser as a device for transmitting remote control signals to replace an infrared transmitting pipe or a radio wave transmitting antenna of a traditional remote controller; consequently, the remote controller is also provided with a laser driving and transmitting circuit matched with the semiconductor laser; the laser driving and transmitting circuit is connected between the semiconductor laser and the coding circuit. The utility model utilizes the characteristics of high directivity and strong penetrating power of the laser to realize long-distance and accurate-positioning remote control. The remote controller can remotely control long-distance objects or can aim at each controlled object to singly conduct remote control when a plurality of controlled objects exist in a controlled area.
Description
Technical field:
The utility model relates to a kind of telepilot.
Background technology:
At present infrared remote controller and radiowave remote control applications are more extensive, but all there are following problem in infrared remote controller and radiowave telepilot: 1, the distance controlled of telepilot is short; If 2 at certain region memory at a plurality of controlled objects, then be difficult to accomplish some targets are controlled and do not influenced other target.Such as on the showcase of market, putting televisor 20 same model, in running order, when with infrared remote controller or radiowave telepilot when wherein a certain televisor controlled, other 19 televisors all can move simultaneously.
Technical scheme:
Fundamental purpose of the present utility model is to provide a kind of remote control distance long or still can implement the telepilot controlled separately at each controlled object when a plurality of controlled object is arranged in controlled area.The technical scheme that realizes this purpose is as follows: a kind of telepilot, comprise button Acquisition Circuit and coding circuit, this telepilot adopts the device of semiconductor laser as the emission remote signal, it also is provided with the Laser Drive radiating circuit that matches with this semiconductor laser, and this Laser Drive radiating circuit is connected between semiconductor laser and the coding circuit.
Wherein, the Laser Drive radiating circuit can be simple, as to adopt the triode modulation to drive a laser modulation circuit, also can be the laser modulation circuit that the band automated power is regulated (APC) circuit, this circuit be disclosed in 26 days October calendar year 2001 of our company to State Intellectual Property Office's application, application number is 01129828.6, denomination of invention is in the patented claim of " power control circuit ".
Laser instrument can adopt the semiconductor laser of different wave length, as 635nm laser instrument, 650nm laser instrument, 780nm laser instrument, 808nm laser instrument, 850nm laser instrument, 980nm laser instrument, 1310nm laser instrument, 1550nm laser instrument etc.The different application occasion is adopted corresponding special wavelength laser instrument, can increase remote control distance (can far reach beyond hundreds of rice) effectively and regulate the remote control area; And can penetrate barrier (as casement etc.) between telepilot and the receiver effectively.
Before the laser instrument of telepilot, also can fixedly install focusing lens, the light beam that laser instrument sent is collimated or the quasi-parallel adjusting, regulate remote control distance and telepilot institute coverage.
The utility model replaces the infrared transmitting tube or the radio wave transmission antenna of traditional remote controller with semiconductor laser, utilize the high directivity of laser instrument, the characteristic that strong penetrating power is long transmission distance, realize remote and accurately location remote control, other controll plant to the control area does not exert an influence.The utility model has been widely used in control fields such as remote control window, market TV group control and remote control demolitions.
Description of drawings:
Fig. 1 is a principle of work block scheme of the present utility model;
Fig. 2 is a practical circuit electrical schematic diagram of the present utility model;
Fig. 3 is the workflow diagram of CPU (central processing unit) of the present utility model;
Fig. 4 is the utility model Laser Drive block scheme.
Specific embodiment:
As shown in Figure 1, telepilot described in the utility model mainly is made up of button Acquisition Circuit, coding circuit, driving and modulation circuit, semiconductor laser four parts in regular turn, and wherein button Acquisition Circuit and coding circuit are all realized by central processing unit (single-chip microcomputer) circuit usually.
When central processing unit collects the signal that certain instruction key presses, produce coding immediately corresponding to this button, through drive and modulating circuit modulates after launch light pulse by laser instrument corresponding to this encoded radio.After the receiving circuit that is installed on controlled object partly receives these light pulses, by just identifying corresponding instruction after opto-electronic conversion and the decoding.
Be a practical circuit that is applied to the remote control window as shown in Figure 2:
Driving and modulation circuit partly adopt the simplest triode modulation circuit in this practical circuit, CPU (central processing unit) adopts the single-chip microcomputer 89C2051 of American ATMEL, vibration partly is made up of quartz crystal Y1 and capacitor C 2, C3, quartz crystal Y1 can select 4MHZ or 12MHZ crystal oscillator for use, capacitor C 2, C3 generally select the 47pf ceramic disc capacitor for use, and laser instrument is selected the 980nm semiconductor laser for use in this example.
The course of work of this circuit is as follows:
12～19 pin by central processing unit single-chip microcomputer 89C2051 are formed keyboard scanning circuit, central processing unit determines that by keyboard scan which key presses, the generation modulation signal of encoding, export the driving circuit of forming through triode T1, R1, R3 by single-chip microcomputer 89C2051 crus secunda P3.0, drive semiconductor laser LD, semiconductor laser LD launches the pulsed laser signal of being modulated, and the other side receives and promptly can control corresponding controll plant through decoding after head receives.
The telepilot that present embodiment is made can be controlled 50 meters windows far away, and can control one of them window arbitrarily and do not influence other window (distance between general two windows is about 2 meters).
