Micropower wireless remote control radiating circuit of the present invention comprises: an operating unit is used to send the open and close signal; A logic control element, the control signal that is used for operating unit is sent is carried out logical process, can not produce mistake control, out of control; A coding unit has 12 three-state address pin, is used for supporting up to 531441 (or 3
12) coding of individual address, can greatly reduce the conflict of sign indicating number and illegally coding is scanned so that the possibility of mating has very strong anti-interference; A reference signal unit, use surface acoustic wave (SAW) frequency very stable, the very little reliable 477-566MHZ high-frequency signal of influence that changed by temperature and loaded impedance, be used for direction-free emission, this frequency band meets national request for utilization, and be the following micropower of 10mw, can not produce and disturb other products; Display unit: adopt light emitting diode or liquid crystal display mode to finish, be used to show the implementation status of transmitter amount of batteries and display operation state; A DC/DC converter unit links to each other with operating unit, display unit, logic control element, coding unit, reference signal unit;
Micropower wireless remote control receiving circuit of the present invention comprises: a receiving element, be used for receiving modulated wireless signal, amplify, filtering one vibration frequency stabilization again filtering one shaping amplify filtering once more, obtain stable modulation signal; Decoding unit, signal processing unit are used for modulation signal and carry out demodulation, and carry out appropriate signals and handle, to control different controlled devices respectively; Carry out driver element for one, the demodulation trigger pip is amplified, be used to connect both sides' controllable silicon, small-sized high-current relay, solid-state relay etc.; A signal feedback unit is used for carrying out driving, after finishing, in time gives radiating circuit with signal feedback, so that under the situation that intercepts sight line, in time understands the duty of controlled device; A load unit, because of utilizing relay contact, or bidirectional triode thyristor etc., executive circuit is the separation state with the receiving unit of itself, can not produce interference, can effectively control all resistive, capacitive and inductive load;
Compared with prior art, the invention has the beneficial effects as follows: in 470～566MHZ frequency, from the power supply to the load, do not increase any anti-sorrow element of doing and overcome and do sorrow because of motor spark and cause influence frequency; Sensitivity is better than-95Db, and the receiving range zero load has under the loading condition more than or equal to 30 meters more than or equal to 80 meters; No matter be perception, capacitive, resistive load can both be worked reliably; Can some products of usefulness except 315MHZ, 433MHZ frequency range, also can be used for the wireless remote control of various light fixtures, window, door and various teleswitches etc.
