Abstract

A kind of remote-controlled electric toy with memory function, comprise the receiving circuit, signal processing circuit, drive circuit, the execution unit that are installed on the electronic toy, and supporting remote control transmitter etc., it is characterized in that also having on the electronic toy single chip circuit MCU, the signal input port of single chip circuit, be connected to the signal output part of original signal processing circuit, the signal output port of single chip circuit is connected to the input of original drive circuit.Its meaning is to have realized memory and the playback to the various remote control actions of electronic toy, increased the interest of toy, its technical scheme also makes the circuit of realizing this function simpler, and peripheral component still less, and when playback mode, can use more convenient without remote controller.

Description

The remote-controlled electric toy of band memory function

Technical field the utility model relates to a kind of remote-controlled electric toy.

The background technology remote-controlled electric toy is the common toy of a class, generally form by electronic toy and supporting remote controller, can finish exercises by the remote controller remote-controlled electric toy, as the advancing of telecar, retreat, turn left, right-hand rotation etc., but prior art can't be remembered and resets these actions.

The summary of the invention the purpose of this utility model is to disclose a kind of remote-controlled electric toy that can remember and reset remote control actions.

The purpose of this utility model is to realize like this, it comprises receiving circuit, signal processing circuit, drive circuit, the execution unit that is installed on the electronic toy, and supporting remote control transmitter etc., its technical characterictic is: also have single chip circuit MCU on the electronic toy, the signal input port of single chip circuit, be connected to the signal output part of original signal processing circuit, the signal output port of single chip circuit is connected to the input of original drive circuit.

The utility model is connected with the single chip circuit as memory and playback between the signal processing circuit of electronic toy and drive circuit, memory and playback have directly been realized to the various remote control actions of electronic toy, increased the interest of toy, its technical scheme also makes the circuit of realizing this function simpler, peripheral component still less, and when playback mode, can use more convenient without remote controller.

Description of drawings Fig. 1 is a kind of remote control circuit schematic diagram of existing electronic toy.

Fig. 2 is the circuit theory diagrams of electronic toy among the utility model embodiment.

Specific embodiment Fig. 1 is existing remote-controlled electric toy a kind of remote control circuit commonly used, (its operation principle sees that domestic unified edition number is the article " a kind of circuit analysis of telecar " of " electronics newspaper " the 37th phase in 2002 of CN51-0091), Fig. 1 the first half is the circuit of remote controller, IC1 and K1-K5 etc. form coding circuit, corresponding to advancing, retreat, turn left, turn right, accelerating motion, Q1 and Q2 form high frequency transmission circuit code signal are launched.The latter half of Fig. 1 is reception and the control circuit that is contained in the electric motor car, Q3 etc. form high frequency receiving circuit, its output is connected to composition signal processing circuits such as IC2, IC2 is the special-purpose decoding chip supporting with remote controller, signal to high frequency receiving circuit is decoded, and the signal (high level is effective) of output multichannel remote control actions, as the 11st, 10,6,7,12 pin are respectively and advance, retreat, turn right, turn left, the signal output part that quickens, after the drive circuit that the actuating signal of signal processing circuit output is made up of triode Q4-Q17 etc. amplifies, drive promptly main motor M 1 of execution unit and steer motor M2, electric motor car is finished advanced, retreat, turn right, turn left, the remote control actions of quickening.

Among Fig. 2, embodiment of the present utility model is between the signal processing circuit and drive circuit of electronic toy, add single-chip microcomputer (MCU) IC circuit 3 of a slice as memory and playback, the I/O mouth P1.3-P1.7 of IC3 is as data input pin, be connected to decoding output the 11st, 10,6,7,12 pin of signal processing circuit IC2 by resistance R 1-R5, the I/O mouth P3.1-P3.5 of IC3 is as data output end, be connected to the input of drive circuit by diode D1-D5 and resistance R 6-R10, promptly on the base stage of Q4, Q7, Q10, Q13, Q16.The I/O mouth P1.1 pin of IC3 is connected with K switch 11 function switch as memory/playback, the I/O mouth P1.2 pin of IC3 be connected with K switch 12 to start with/shutdown switch, remember or the beginning of playback and stopping controlling.

The working procedure that the ROM of IC3 the inside is solidified with memory and resets, when K11 is in remember condition, click K12 when memory work is started, the P3.1-P3.5 mouth of IC3 is all put low level, do not influence the straighforward operation of original circuit, the state of program cycle scans I/O mouth P1.3-P1.7 simultaneously, and start a counter and carry out time counting.At this moment the user can pass through remote controller, the remote control actions that the remote control electric car advances, retreats, turns right, turns left, quickens, at this moment the 11st of IC2 the, 10,6,7,12 pin will be exported control signal (high level is effective) according to remote control actions, and the variation of these level signals will be input to the P1.3-P1.7 mouth of IC3 by resistance R 1-R5, scanned by program, when program scanning arrives the level variation of these I/O mouths, port title, port status value (1 or 0) sum counter numerical value are stored among the RAM of IC3 in the lump, finish memory function.

After finishing the memory of remote control actions, when K switch 11 is in playback mode, click K12 and begin playback time, program also restarts counter, timing numerical value according to counter, store one group of data that the RAM the inside is read the count value correspondence successively from data, and its state value (1 or 0) outputed on the corresponding port, be connected to the input of drive circuit again by diode D1-D5 and resistance R 6-R10, be Q4, Q7, Q10, Q13, on the base stage of Q16, the control electric motor car reproduces advancing of original memory, retreat, turn right, turn left, the function of playback is finished in actions such as acceleration.

Present embodiment adopts general MCU chip to cooperate peripheral component to come work, also diode D1-D5 and resistance R 1-R10 can be encapsulated in the chip the inside in the practical application, becomes special chip, saves peripheral component.Narration for convenience, embodiment separates the data-in port of IC3 with output port, in the practical application, for most MCU chips, the input of its data and output can shared ports, port as output, can be saved number of pins as input like this when playback mode when remember condition.

The memory of present embodiment/playback is changed and is begun/stop control and adopts the switch direct control, in the practical application, also can send certain special remote signal by remote controller, discern by software and to control, such as, remote controller was sent three of short duration progress signals continuously in one second, software just is identified as " memory " state of putting, in one second, send three of short duration backing signals continuously, software just is identified as " playback " state of putting, in one second, send three of short duration left rotaring signals continuously, software just is identified as " beginning ", sends three of short duration right turn signals in one second continuously, and software just is identified as " stopping ", so just, can change the structure of original electronic toy, and use more convenient.

For the MCU chip, its program function and operation principle have been narrated here, for the specific procedure of the inside, the technical staff in microcomputer development field, according to above-mentioned program function of introducing and operation principle, just can compile out program, so need not provide original program here.
