Abstract
The invention discloses a novel low-power-consumption integrated circuit applied to photographing, gating and smart home remote control. The circuit comprises a radiofrequency remote controller and a receiver chip. The remote controller and the receiver realize one-to-one connection, and the probability of wrong receipt or wrong remote control is below ten percent. Compared with the existing infrared remote control receiver, the integrated circuit has long-distance effect and is capable of solving the defect that infra-red technology cannot work normally under bright sunshine. The controller and the receiver adopt 434 MHz industrial, scientific and medical ISM radiofrequency. As the design of integrated circuit chips is adopted, the receiver chip has a small volume and is convenient to integrate with the existing digital camera, and the remote controller is quite small and exquisite, and can be hung to a key ring actually, photographing in travel by users and the application to smart gating and smart home are facilitated to a great extent.
Description
Technical field
The present invention relates to telechiric device, particularly provide a kind of can be to wireless telepilot of controlling of traditional home appliance and receiver.
Background technology
Must develop along with scientific and technological, household electric appliances makes rapid progress, and a lot of household electrical appliance are just brought into use telepilot as far back as the 80s and 90s, as televisor, electric fan, video recorder etc., yet one very serious that problem is, increases along with the needs remote control must set, and telepilot is also more and more, make straighforward operation also more and more bother, as a small portable compact electric apparatus, when using in the open air, even telepilot is arranged, if can the telepilot volume too big, also lost portable electricity consuming products itself advantage; Simultaneously the remote control distance of existing equipment telepilot also is very limited, and distance slightly far just can't operate as normal; Existing in addition a lot of infrared remote controllers are subjected to sunlight must be influenced also very greatly, so it is little to be badly in need of a kind of volume, operating distance is big, be not subjected to sunlight influence telechiric device.
Summary of the invention
The object of the present invention is to provide a kind of novel photographing, remote control gate, Smart Home telepilot and receiver, it comprises telepilot and the receiver that is installed on the master controller, wherein:
This telepilot emission radio-frequency electromagnetic field signal comprises oscillator, key encoder, frequency mixer and power amplifier and emitting antenna;
This receiver receives control signal, comprises receiving antenna, amplifier, and frequency synthesizer, frequency mixer and demoder,
Antenna induction is behind the radio-frequency electromagnetic field signal, change into the radio circuit signal, low noise amplifier amplifies signal, the constant local frequency mixing of exporting then by down-conversion mixer and frequency synthesizer, generate intermediate-freuqncy signal, demoder is decoded into original control signal with intermediate-freuqncy signal, and when original control signal had comprised the receiver identification code, demoder was exported control signal to master controller.
Control signal adopts frequency shift (FS) modulation FSK or OOK, is converted to 434,000,000 ISM channels; 0 usefulness, 8 cycle 1MHz represents that 1 usefulness, 16 cycle 2MHz represents that control code adopts frame structure, comprises 6 initial codes, long 8 of Target Recognition coding, and long 4 of control coding, 18 altogether of data are launched one group of data times spent 144 microsecond, launch 40 groups of data continuously.
Because it is adopt design of integrated circuit, the receiver chip volume is very little, convenient integrated with existing digital camera.Telepilot is also very small and exquisite, can hang over fully on the key chain, has greatly made things convenient for user's out on tours to take pictures, intelligent gate, and Smart Home is used.
Description of drawings
Accompanying drawing 1 is the embodiment of the invention 1 camera telepilot and receiver synoptic diagram;
Accompanying drawing 2 is the embodiment of the invention 2 camera receiver synoptic diagram.
Embodiment
As shown in Figure 1, the embodiment of the invention 1 is used for the radio-frequency (RF) remote that remote control is taken a picture, and it comprises oscillator, key encoder, and frequency mixer and power amplifier and antenna, oscillator can comprise low-cost crystal oscillator, the high frequency annular voltage controlled oscillator.Power amplifier is common amplifier.
Antenna induction is behind the radio-frequency electromagnetic field signal, change into the radio circuit signal, low noise amplifier amplifies signal, then the constant local frequency mixing of exporting by down-conversion mixer and frequency synthesizer, generate intermediate-freuqncy signal, demoder is decoded into original control signal with intermediate-freuqncy signal.When original control signal had comprised the receiver identification code, demoder just can be exported the control signal of taking pictures to master controller.
When camera was adjusted to remote control mode, receiver was started working.After receiving radiofrequency signal, directly conversion of signals is become zero intermediate frequency.Deciding output according to the down-conversion mixer output frequency is 0 or 1, after detecting initial code and correct identification code, control code is passed to main control cpu.
As shown in Figure 2, the embodiment of the invention 2, a kind of more senior bidirectional remote control receiver, can this bidirectional remote control receiver have increased a sound indication at the hand-held remote control unit end, be used to indicate camera continue to take pictures.When camera since in be filled with or battery does not have electricity and can't continue to take pictures the time, can send the sound of " dripping " by telepilot and warn the person of taking pictures.
The demand different according to the consumer, the simplest telepilot can have only a button, is used for controlling taking pictures.Complicated any can also increase the remote-control closedown function, and adjustment aperture commonly used, continuous shooting or the like.
The present invention is applied to take a picture, gate, and the novel low power consumption integrated circuit of Smart Home remote control comprises radio-frequency (RF) remote and receiver chip.Telepilot and receiver are realized corresponding one by one contact, and the probability that misconnection receipts or mistake remote control take place is below 10/1000000ths.Compare with existing infrared remote control receiver, this invention operating distance is long, can solve infrared technique can not be under bright and beautiful sunlight the shortcoming of operate as normal.This telepilot and receiver adopt 434,000,000 industry, science and medical ISM radio frequency.
Because it is adopt design of integrated circuit, the receiver chip volume is very little, convenient integrated with existing digital camera.Telepilot is also very small and exquisite, can hang over fully on the key chain, has greatly made things convenient for user's out on tours to take pictures, intelligent gate, and Smart Home is used.
The above only is preferred embodiment of the present invention; be not to limit to the present invention with this; therefore; all all and structure of the present invention, device, feature etc. are approximate, identical; be allly to replace and modify etc. according to patent claim of the present invention being equal to of doing, all should still belong within the scope of patented claim protection of the present invention.
