Embodiment
Below by concrete example with reference, the present invention is described in further detail.
F1 and F2 is supply socket as shown in fig. 1, is convenient to radio transmitter and is connected in the middle of air-conditioning F7 circuit, and F3 is sampling and power converting circuit, and F4 is rectification, filtering, mu balanced circuit, and F5 is establishment decoding circuit, and F6 is high-frequency data radiating circuit.
During the work of compressor of air conditioner shown in Fig. 2, electric current reaches more than 4 amperes, after the former limit being added in transformer B1, will to induct certain voltage at the secondary of transformer B1 by certain turn ratio, the present invention is set to 16.5V voltage, through fuse FU, bridge heap VD1-VD4 rectification, C1, C2 low frequency High frequency filter, 12V burning voltage is exported through integrated steady device 78L12 voltage stabilizing, VD5 is the diode that protection 78L12 is arranged, C4 is high-frequency filter capacitor, C3 is low frequency filtering electric capacity, but the more important thing is and play energy storage effect, when compressor of air conditioner quits work, radiating circuit utilizes the energy storage of C3 also will to work certain hour, until relay J 1 dead electricity contact switch is from 2 to 1, radio transmitter outwards sends off signal.
In Fig. 2, LX2260A-R4 is that a wireless remote control that uses of matching with SC2272-L4 is encoded special IC.Adopt 8 bit address codes and 4 bit data codes, totally 12 kinds of states, at this moment the address setting pin of coding circuit LX2260A-R4 and decoding SC2272-L4, there are three kinds of states available: unsettled, connect positive supply, ground connection three kinds of states, the maximum three-state address code pin having 12, can support nearly 265720(or 3
12÷ 2) geocoding, significantly reduce the repetition rate of coding very much.Only have transmitting terminal LX2260A-R4 identical with the geocoding of receiving end SC2272-L4, could match use, when compressor of air conditioner work, when 78L12 output voltage reaches 12V, relay J 1 adhesive, when LX2260A-R4 the 13rd pin receives one end of resistance R5 by relay adhesive, be set to "On" state, at this moment Q3 work, IC, Q1 is energized work, LX2260A-R4 the 15th pin output address data coded signal, Q2 makes Data Modulation, Q1 makes the higher-order of oscillation, outwards launch finally by antenna, LX2260A-R4 the 12nd pin receives one end of resistance R5 by relay electric-loss, be set to "Off" state, same coded data signal is outwards launched by antenna.Consider the Micro Energy Lose requirement of circuit, have employed ASK mode to modulate, the frequency of operation of data transmission module is 315M, employing sound table resonator SAWR315 frequency stabilization, frequency stability is high, is only second to crystal, when environment temperature changes between-25 ~+85 degree, frequently waft and be only 3ppm/ degree, be particularly suitable for multiple one and receive wireless remote control and data transmission system.
Data transmission module of the present invention has wider operating voltage range 3 ~ 12V, when emitting voltage is 12V, is optimum operating voltage, has good launching effect.General opening maximum launch range about 800 meters, when there being obstacle, distance can shorten, and actual range, greatly about about 30 meters, can meet the requirement controlled completely.When change in voltage, transmission frequency is substantially constant, and the supporting receiver module of transmitter module just can stably receive without the need to any adjustment.When compressor of air conditioner quits work, B1 original edge voltage diminishes immediately, decline rapidly from 12V through 78L12 stabilized voltage supply voltage, relay J 1 dead electricity, its contact is allocated to 1 from 2, scrambler LX2260A-R4A-R4 sends shutdown coded signal, and wireless data transmission module voltage, until when reducing to 3V, also can work, launch off signal, still can control controlled plant shutdown.
Fig. 3 is radio receiver block diagram of the present invention, and in figure, SP1 switch has three positions, and " 1 " shuts down, " 2 " normal open, " 3 " are automatic, and K1 is rectification, filtering, mu balanced circuit, and K2 is decoding circuit, K3 is high frequency receiving circuit, and K4 is executive circuit, and K5 is controlled two axial flow blowers of the present invention.
Fig. 4 is radio receiver circuit theory diagrams of the present invention; when SP1 switch pushes " 3 " automatic transmission; the voltage of alternating current 220V reduces to the alternating voltage of 16.5V through B1; again through FU fuse, the rectification of VD1-VD4 bridge heap; C1, C2, C3, C4 filtering, 78L05 voltage stabilizing, becomes galvanic current pressure; for subsequent conditioning circuit is powered, VD5, VD6 are protection diode.
Fig. 5 is conventional superregenrative reception modular circuit schematic diagram, in figure, Q1 etc. form High Amplifier Circuit, Q2 and related elements composition superregenerative detection circuit, the control signal detected carries out, after amplification process, outputting to 14 pin of the SC2272-L4-L4 decoding chip Fig. 4 from output terminal 1 pin through ICLM358 two stage amplifer.Data are compared in SC2272-L4, only have transmitting terminal LX2260A-R4 identical with the geocoding of receiving end SC2272-L4, and when geocoding is completely the same, the data terminal that receiver is corresponding exports the control signal identical with transmitting terminal.Data terminal 12 pin of SC2272-L4-L4 exports, and amplifies promote relay J 1 action through R2, Q1, and control contact J controls axial flow blower F1, F2 and opens, stops.
