As shown in Figure 1, this is the wireless logical control of remote controller block diagram of the utility model multi-channel rf, and it is made up of the signal transmission circuit of emission mobile phone and the signal receiving circuit of receiver.The top of Fig. 1 is the signal transmission circuit control block diagram of emission mobile phone, and it comprises: one 16 bit keyboards, and it is 4 * 4 16 bit keyboards; In order to 4 * 4 16 bit keyboard data conversions are become the keyboard signal generation circuit of 4 bit binary data; The hyperfrequency radiating circuit that is connected to the coding circuit that binary data is encoded behind the keyboard signal generation circuit in turn and launches; The signal receiving circuit control block diagram of the bottom receiver of Fig. 1, it comprises: the hyperfrequency receiving circuit of Lian Jieing, decoding circuit, 4 change 16 decoding circuits, relay array, diverter switch array composition successively.
As shown in Figure 2, this is the electrical schematic diagram of the utility model emission mobile phone.It comprises: by integrated circuit U3, U1, U4 model is the keyboard circuit that MC4051, MC4520, MC4001 integrated circuit constitute, the data conversion of 4 * 4 keyboards is become 4 bit binary data, sending into by integrated circuit U5 model is that the encoder of HT-12E is encoded, and by HT-12E output serial data signal, after the emission of high-frequency emission cells modulate.Wherein keyboard circuit is a scan-type, and it can prevent the misoperation that two keys are pressed simultaneously.
Its operation principle is: when a certain key was pressed, Vcc was through the 3rd pin input of U2, and the row, column crosspoint through being pressed is sent by the tripod of U3 again; This signal will force by U4/A, the blocking of oscillator that U4/D constitutes, thus make counter 4520 also stop numeration at some states, and the Q0-Q3 of this state just in time is two 4051 states of being connected, just this example of pressing of button and position of row.U4/B plays the vibration prevention effect, and it can send a low level when button is pressed, and it will make 4520 to stop numeration, and what this signal also will be used for U5 enables to control triggering with monostable circuit.
HT-12E is the coding circuit of a special use, and matching used decoding circuit is HT-12D.Its major function is that 4 bit binary data are become serial code, the 17th pin output by slice, thin piece, its 1-8 pin is A0-A7 address setting position, can make ternary coding, amount to 6561 kinds of coded systems, in native system, be mainly used in set oneself for different user password to avoid the phase mutual interference, and the 10-13 pin is the D0-D3 data input pin, can import 16 kinds of states altogether, is respectively applied for 15 self-locking switch controls and the control of always making zero in native system, the 14th, the Enable Pin of slice, thin piece, during with its reset, the oscillator of slice, thin piece is started working, and 15-16 is the oscillation resistance terminals, the 17th, serial code output, 9,18 is respectively ground connection and power supply.The high-frequency oscillating circuits that is made of T1 is operated in about 260MHz, constitutes oscillator coil with the Copper Foil on the printed circuit, and it also is a transmitting antenna simultaneously.Constitute a monostable circuit and multi-resonant oscillating circuit by one 4011 circuit, be respectively applied for indication of keyboard noctilucence and flashing lamp circuit.Triggering signal is delivered to 4011 the 1st pin by 4001 the 4th pin when a certain button is pressed, and exports 30 seconds low level of time-delay through monostable circuit, and lights keyboard by 6 light-emitting diodes of T2 driving.
As shown in Figure 3, this is the signal receive section circuit diagram of the utility model receiver, and radio signal is received by antenna, amplifies through Q4 superregenerative formula amplifier, after the Q5 detection is amplified, send into the 14th pin decoding of the HT-12D among Fig. 4 after amplification of U4 operational amplifier and the paraphase of Q6 phase inverter.
As shown in Figure 4, this is the signal processing circuit diagram of the utility model receiver, and HT-12D is and the matching used decoding circuit of HT-12E among the figure.The 1-8 pin is an A0-A7 address setting end, when the address state through state consistency that HT-12D is provided with at this moment in receiving circuit that radiating circuit HT-12E sets, but HT-120 just decipher go out the data that reflector sends.Otherwise if the address state difference, HT-12D will can not separate sign indicating number.This remote controller utilizes this principle to distinguish the signal of different user.The decoded data of HT-12D are sent by D0-D3, in the HT-120 decoding effectively simultaneously, its 17th pin also will be sent a high level, expression " decoding successfully ", native system with this signal and D0-D3 signal together send into U4 " with door " circuit ask with, to improve interference free performance.These 4 binary signals are sent into U2 again and are carried out 4-16 line decoder for decoding then, translate S0-S15 totally 16 road signals altogether, wherein S1-S15 will send into the self-locking switch that is made of the d type flip flop array, and this switching signal will be carried out switch control to load by driving 15 relays of triode array or special driving chip driving at last.
U5/D and R among the figure, C constitutes into the start clear circuit, and after total reset signal in the reflector is received device and receives, 17 pin of HT-12D will exports " 1 ", the S0 end of MC4514 is exported " 1 ".Send " 1 " signal through U5/A, U5/C this moment all makes zero all d type flip flops, causes all relays all to be closed.And when reflector did not transmit, although the D0-D3 of U1 also is " 0 ", the S0 of U2 end also was " 1 ", and because of the TEST end of U1 is " 0 ", this signal has been shut U5/A, and makes the pin of U5/C not be " 1 ", and d type flip flop can misoperation.U5/B and N1 among the figure, S2 constitute to receive and to reply the acoustic-electric road, when receiver is received the signal that reflector is sent and after U1HT-12D decoded successfully, buzzer S2 can sound.
As shown in Figure 5, this is to drive and output circuit in the utility model, it is composed in series by the inductance and the diode of transistor AND gate parallel connection, this is the switching signal by the output of the d type flip flop array among Fig. 4, to be sent to by N1 R1, JC, driving triode and relay array that D1 forms switch on or off load by relay.
As shown in Figure 6, this is that the utility model and switch on wall share the winding diagram of forming ganged switch, what represent among the figure is the ganged switch winding diagram of the utility model remote controller and the coupling of common hilted broadsword two-position switch, frame of broken lines is the control element in the expression receiver among the figure, S3 wherein, S4 are " wireless logical " " leading directly to ", the diverter switch of " cut-out ", this switch is used to meet an urgent need, the usefulness of maintenance " wireless logical ".
As shown in Figure 7, this is to use the winding diagram of the utility model remote controller, adopt this connection to save and switch is installed on the wall and is arranged switching line, frame of broken lines is the control element in the expression receiver among the figure, wherein, S4 is " wireless logical " " remote control " diverter switch, and this switch is used to meet an urgent need, the usefulness of maintenance " wireless logical ".
In sum, the utility model Multi-channel radio frequency radio communication remote-controller utilizes the conduct of ultra-high frequency wireless electric wave Transmission medium is controlled controlled unit, each corner that its control range can be in 10 meters of radiuses, And can pass through wall, can realize thus " wireless, wired ganged switch " mode, and needn't be on wall The trouble of switch is installed, and novelty, convenience, practical advantage are arranged.
