And a motor driving section 50 for controlling the rotation direction, and a storage section 60 for storing program source codes transmitted from a computer.

The power supply unit 10 is for supplying power used in the toy control device, and receives power from a DC power inserted into the toy and supplies the power to a portion that requires power. In addition, the power supply 10 may further be connected to the variable resistor (VR) to adjust the voltage or current value to the load of the circuit. This is also shown in FIG. 3. In the drawing, the "x" symbol is an unused open terminal. A voltage of about 5 to 35 V is applied to the power supply unit 10. The applied voltage is output as the Vcc voltage after the voltage is changed by the IC 7805. The output voltage is mainly used to operate the driving motor and the one chip microcomputer 20.

The one-chip microcomputer 20 has a built-in compiler or interpreter for a specific program language and includes a plurality of input / output terminals, and outputs an operation control signal according to a program. An IC with a built-in compiler or interpreter for a specific program can be purchased commercially. In the present invention, an example using a PIC BASIC module (PIC16C73A) having an interpreter for a basic language will be described. However, not only basic, but also ICs with built-in interpreters for programming languages such as Basic, q-Basic and Visual Basic, and compilers for assembly languages, C, C ++ and Fortran The program language can be used.

In addition, the one-chip microcomputer 20 is provided with a plurality of input / output terminals. The input / output terminals P0, .., P15 are bidirectional I / O terminals whose inputs or outputs are mutually compatible as necessary, and may output a signal for controlling the driving motor or receive a signal from an external source. . The signal input from the outside may be, for example, a signal input from various sensors such as a temperature sensor, an ultrasonic sensor, an infrared sensor, and the like. Although 16 input / output terminals are shown in the figure, a one-chip microcomputer with input / output terminals further extended as necessary may be used.

In addition, the reset part 22 is further connected to the one-chip microcomputer 20. The reset unit 22 is for initializing the one chip microcomputer 20 when an error occurs in the one chip microcomputer 20 and the toy control device does not operate. A detailed circuit diagram is shown in FIG. As shown in the drawing, when the reset switch sw is pressed, a reset signal is generated from the Schmitt trigger not gate 74HC14 and input to the one chip microcomputer 20 to initialize the one chip microcom 20. Let's do it. After initialization, the program loaded in the storage unit 60 is interpreted or compiled again to control the toy.

In the present invention, the source codes of the programs are written to a computer and then transmitted to the one chip microcomputer 20. At this time, the connection means used for the transmission of the program source code is the interface unit 30. The interface unit 30 is configured to be separated from the toy and the computer in order to free the operation of the toy. Accordingly, the interface unit 30 includes a jack 34 portion connected to the one chip microcomputer 20 and installed in the toy control device, and one end thereof includes a printer port connecting jack 36 connected to the printer port of the computer, and the other end thereof. It is separated into two parts of the jack 32 which is connected to the jack 34.

Referring to FIG. 1 again, the one-chip microcomputer 20 has a jack 34 connected to each other through three wires, and is separated from the jack 34, and also has a jack 32 mated with the jack 34. It is also connected to the printer port connecting jack 36 by a wire. The printer port connecting jack 36 is directly connected to a printer port provided at the rear of the computer. Numbers displayed on the rear of the printer port connection jack 36 are pin numbers, and represent pins to which wires are connected, respectively, in the drawing, pins 2, 10, and 25 are connected, and number 25 represents ground.

The program source transmitted through the interface unit 30 is stored in the storage unit 60 after passing through the one chip microcomputer 20. It is essential that the storage unit 60 repeatedly stores and erases the program source, and for this purpose, it is preferable to use an EEPROM, which is a memory device capable of repeatedly writing / erasing. The program source stored in the storage unit 60 is usually stored as a hex file, and when the toy is operated, it is interpreted or compiled after being called by the one chip microcomputer 20 and executed in the one chip microcomputer 20. An example of a basic program source for a basic interpreter is described below with reference to FIG.

One chip microcomputer 20 is provided with a plurality of input / output terminals, each of which may be connected to the sensor detecting unit 40 and the motor driving unit 50 to detect the toy environment and to operate the toy. Referring back to FIG. 1, the sensor detecting unit 40 includes a light emitting diode for generating light and a photosensor 42 having a phototransistor for receiving light reflected from an object. A pair of photosensors 42 are connected.

The electrical signal output from each of the photosensors 42 passes through the Schmitt trigger not gate 74HC14 and is arranged as a clean signal and then outputted. Is entered. The one chip microcomputer 20 has a plurality of terminals as described above, and each terminal is bidirectional so that the output signal is connected to an appropriate terminal.

The load resistor RL is connected to the phototransistor collector of the photosensor 42, and this value can be maintained at about 10 mV to maintain a stable operating state. It may be larger than this value, but if it is smaller than this value, there is a problem of unstable operation. The signal output from the photosensor 42 is connected to the input terminal of the one chip microcomputer 20, respectively.

As the device operating on the control signal from the one-chip microcomputer 20, the motor driving unit 50 can be used. The motor driving unit 50 is configured to control the speed, rotation direction, etc. of the driving motor 56. Referring to FIG. 1, when a control signal is output from the output terminal P0 of the one-chip microcomputer 20, the transistor ( The power supply on / off unit 52 supplies power to the driving motor 56 by C3198, and the rotation control unit 54 is operated by the transistor C3198 by a control signal output from the output terminal P1. The rotational direction of the drive motor 56 is controlled. According to the rotational direction of the drive motor 56, a toy, for example, a model car can perform the forward, reverse operation. In the case of controlling the drive motor 56, two output terminals of the one-chip microcomputer 20 are used. The power on / off controller 52 and the rotation controller 54 may be configured using a relay.

In addition, it is possible to check the on / off of the power on / off control unit 52 using various colors of light emitting diodes (LEDs), as well as a flashing light can be a colorful decoration when operating at night.

The motor driving unit 50 can be further extended as needed. This is changed according to the complexity and expandability of the toy to which the apparatus of the present invention is applied, and as shown in FIG. 2, four drive motors 56 can be connected to perform more complicated functions. For example, if the toy is a model tower crane, use one drive motor to move forward and backward, another drive motor to change direction, another drive motor to move the crane, And the last one can be used to change the direction of the tower crane.

The same can be applied to the driving motor of the model robot.

In addition, a small fan can be installed in the spare part of a plurality of drive motors in order to have variety as needed.

In addition to the motor driving unit 50, the sensor detecting unit 40 may also perform various operations according to the number of sensors and the sensing method of the sensor. For example, in the case of a model car, a light sensor such as a light emitting diode may be used to irradiate light on a line drawn on the floor, and to recognize the degree of reflected light and to program the line along the drawn line. Alternatively, an ultrasonic sensor can be used to recognize the presence of an object in front of the vehicle and control the model car to avoid a collision by performing a turn.

5 illustrates an embodiment of an ultrasonic sensor used as a sensor detecting unit. As shown in the drawing, the transmitter generates an ultrasonic wave and emits the light toward the front, and after receiving the reflected wave reflected from the object, the receiver detects and modulates the signal into an electrical signal corresponding thereto and outputs it. The output electrical signal is input to the one chip microcomputer 20. In the one chip microcomputer 20, it is possible to determine the presence or absence of an object according to the magnitude of the electrical signal and take appropriate measures.

An example of the control program created using the basic is shown in FIG. As shown, it is configured to recognize the values (0, 1) input from the sensors to control the direction of the model car or the like. Commands consist of basic commands that allow you to perform actions such as "turn right", "turn left", "forward", "forward left wheel", "forward right wheel", and so on. The user may define the sub function as a patterning operation.

These basic instructions are written in a text file on a computer and then transmitted to the storage unit 60 of the toy control device embedded in the toy. The transferred program source is later executed after being interpreted in the one chip microcomputer 20. Of course, if the program code is written in a program language other than BASIC, the program code is written as a command of the corresponding program language, which is different from the command shown in FIG. 6 and may require a different one-chip microcomputer according to the compilation process.

In the above example, the program source is created on a computer and transmitted through the interface unit 30. However, when a ROM writer (a device for writing a program directly to a ROM) is used in the related art, a program is directly stored in the storage unit 60. It is also possible to input.

When the present invention is applied to a model vehicle, forward and backward movements of the model vehicle, when an object is placed in front of the model vehicle, by using the sensor of the sensor detecting unit 40 to detect this and to change the direction to the left or right Control to perform an operation such as changing the direction of the.

The same can be applied to the model robot to control a number of drive motors used for joints such as the neck, arms and legs.

In addition, if you apply the device of the present invention to the familiar toys, such as Lego (assembled toys) science box and the latest imported toys robo lap (robo lap), the toys will not get tired in the familiar state already The advantage is that it can be used longer.

As such, using a plurality of driving motors and sensors for sensing can perform a variety of operations. The writing ability of a child or student playing with a toy while writing such a program naturally improves the educational effect.

In addition, by inducing interest in programming, it naturally helps develop logical thinking and creativity, thus effectively training future technical personnel from an early age.

According to the present invention as described above it is possible to perform a variety of operations by arbitrarily controlling the operation unit of the toy according to the program created and transmitted from the computer, and also has the advantage that can help learning by achieving the program acquisition effect through the toy. .
