Development based on electronic stationery, the electronic calculator of pocket has been not limited to simple computation, its function expansion develops into electronics diary (as Casio SF-4000), electronic memo (as Casio QD-800 from storing several names and telephone number, DC-800, IF-8100 etc.), electronic translator aspects such as (as Sanyo's products), has schedule, account, storing phone number, p.m.entry is reported to the police, maintain secrecy, major functions such as calculating, volume are quite small and exquisite, and input mode also develops into screen by the keyboard input and writes input.

The development of electronic stationery makes the present invention become possibility.The present invention promptly selects the combination of electronic stationery and remote controlled transmitting circuit, provides digitally encoded signal by the data register of read/write circuit in the electronic stationery for radiating circuit.Because of the ASCII type sign indicating numbers that adopt in the electronic stationery, the expressed information of binary digit has 128 kinds, so the privacy degrees of remote-control transmitting password has just increased greatly more.

The present invention is achieved in that and with possessing reading and writing, storage, modification character function and being provided with an energy electronic stationery circuit and the remote controlled transmitting circuit of being read the coded lock that character encrypts is combined, " signal input part " of radiating circuit links to each other with the register that reads and writes data of last circuit, and two parts circuit is packed into one to have in the shell of matrix keyboard and LCD screen.Receiver circuit is added a driving topworks of looking different purposes and establishing, the signal output part of o controller connects the signal input part that drives topworks in the receiver circuit, this circuit and driving actuating mechanism circuit are welded on the printed circuit board, if all kinds of electric switches of control drive topworks and can use the solid-state relay on-off circuit; Use if unblank, drive topworks and can match various electronic lock unlocking circuits, if realize control to the electrical equipment that itself possesses the digital proportional remote-control receiver, then only use this remote transmitter to get final product, just need be with the compatible and open control digital signal that receives of receiving element, received signal parameter and transmitter.

Advantage of the present invention: use public use again but can maintain secrecy, be easy to carry about with one, be convenient to popularize, general, degree of reliability height, strong security, transmitter and receiver quantitatively can be compatible.

Introduce the physical circuit and the principle of work of this telepilot in detail below in conjunction with accompanying drawing, along with the development of digital technology, the producer can arbitrarily design the integrated circuit that comprises above-mentioned functions, and it is example that the present invention only selects remote-control transmitting/receiving integrate circuit VT2020E/D for use.

Fig. 1 is the internal logic block diagram of amended VT2020E a little.1. being oscillator among the figure, 2. is time-base generator, 3. is on-reset circuit, 4. is the coded signal modulator, and 9 pin are coded signal input ends.

Fig. 2 is the concrete application circuit of transmitter.

Fig. 3 is the internal logic block diagram of amended VT2020D a little.1. being the biasing circuit of operational amplifier among the figure, 2. is oscillator, 3. is time-base generator, 4. is code translator, 5. is data register, 6. is on-reset circuit, 7. is o controller.The cross-over connection light emitting diode and the button that resets certainly between 15 pin, 16 pin, 16 pin connect a G output.

Fig. 4 is the concrete application circuit of receiver.Fig. 5 is the outside drawing of remote transmitter.

Transmitter adopts the VT2020E that revises a little, this is external CMOS remote-control transmitting integrated circuit commonly used, emissive power is little, and discontinuous operation, power consumption are very low, and volume is also quite small and exquisite, can be loaded in all kinds of electronic stationeries fully, owing to the order code of launching is the character combination of arbitrarily setting or some bit binary number signals that figure comes through circuit conversion, it is extremely low that it overlaps probability, the phase mutual interference in the time of can avoiding multimachine to use fully.

Amended radiating circuit has been cancelled the generation random code function of primary circuit, keep modulation function, order code changes by the register that reads and writes data in the electronic stationery provides, command range is not less than six meters, 2. time-base generator determines the output time of order code, per second serial output two string order codes, when the time span of every string order code is nine character passwords of 140.4ms(), the order code after the modulation is controlled the startup of radiating circuit by the output of integrated circuit 7 pin.When the button AN that resets did not certainly press, the transmitter outage did not have power consumption; When pressing AN, if integrated circuit does not send order code, pin 7 outputs keep high level, power valve Q ₁Still be in cut-off state.When having only pin 7 to have order code to send, Q ₁Just enter amplification region work, so just reach energy-conserving action.In order to save element, radiating circuit and electronic stationery can shared one group of power supply and quartz crystals, only several microamperes of the quiescent dissipations of VT2020E, and power supply can adopt button cell fully, and emitting antenna adopts printed coil.

Receiver also can adopt different circuit according to purposes, if only as not establishing close electric switch, circuit also can be simplified, and the design receives for password, employing be and the VT2020D of VT2020E pairing use just to have carried out some modifications.The modification content comprises: 1, with door G by primary circuit or door change rejection gate into, make a G when circuit is judged effective code, controlling output circuit 12 pin are exported a noble potential steady-state signal, in order to trigger back level executive circuit.2, will disconnect between on-reset circuit and the main circuit, be connected in series a light emitting diode D ₁With the button AN that resets certainly.

3. time-base generator in the receiving circuit guarantees to decipher to receive with digital emission synchronouss working, and the control end EN of pin 14 is also controlling external receiver amplifier simultaneously, as Q ₁Pipe makes it discontinuous operation, and when 4. code translator did not receive the order code of transmitter transmission, the EN end was high level, Q ₁In running order; In case the order code of receiving, the EN end is just controlled Q ₁Interrupter duty, to reduce circuit power consumption, the order code that 5. data register will be received first stores as comparable data, for for the second time later command signal, circuit compares it and the data register comparable data in 5., judge whether to be effective code, if receive effective code, then 7. door G control o controller makes external light emitting diode D ₂Ignite, 12 pin are exported a noble potential steady-state signal, trigger back level executive circuit.If will adjust the reception password, press earlier and change sign indicating number non-locking press-button AN, the input proper password, triggering on-reset circuit by door G 6. works, remove the former comparable data of register in 5., the password that to newly adjust is launched through transmitter again, and 5. the data register in the receiver promptly receives new password and store as new comparable data.
