It is intended to solve the conventional problem by configuring the program storage unit for storing the instruction programs corresponding to the code stored in the RFID tag.

In the present invention, when the RFID card is sequentially contacted in order to control the equipment, a control program is automatically configured and control is performed so that anyone can easily program, and even if an expensive program creation tool or a computer is not provided, Input is possible.

Therefore, since the present invention can be easily used in industrial sites, educational sites, and homes, the present invention has a wide range of applications in various fields.

The present invention will be described with reference to the accompanying drawings 1 and 2 as follows.

1 is a block diagram of a system for realizing the present invention, which is described as an example of a system for configuring an operation program of an educational assembly robot for learning, and not only an educational assembly robot, but also an industrial robot, an industrial plant, and a household An operation related program such as a device can be configured.

RFID tags (110, 120, ...) are embedded in the chip (111, 121, ...) each device, that is, each device such as display unit 261, motor 262, speaker 263, ... Code is stored to select commands that operate as the user intends.

For example, a code for selecting a command for driving the motor 261 is stored in the first RFID tag 110 and a code for selecting a command for receiving a value from the sensor unit 270 in the second RFID tag 120. May be stored, and codes for selecting a command corresponding to the display unit 263, the speaker 262, etc. are stored in the remaining RFID tags.

As a more specific example, an RFID tag designating one of a plurality of motors, an RFID tag for forward and reverse driving control of the motor, an RFID tag for setting an operation time, an RFID tag for designating a speed, and a processor Any one of an RFID tag, a plurality of sensors (ultrasound sensor, light sensor, temperature sensor, human body sensor, infrared sensor, etc.) for designating an output pin to output the control signal output from the 220 to the corresponding pin. An RFID tag, a syntax RFID tag (program syntax such as if else), etc. for designating the same may be provided with various sensors suitable for the purpose.

The RFID reader 210 reads codes from the RFID tags 110, 120,... Which are sequentially contacted according to a user's intention, and provides the codes to the processor 220, and the processor 220 corresponds to an instruction program corresponding to the input code. The program is read from the program storage unit 230 to configure a series of programs for the robot to operate and store in the memory 250.

At this time, if the user inputs a variable value, for example, the rotation direction, the rotation speed of the motor, and the like through the key input unit 240 while the user contacts the RFID tag 110, the variable input position of the command program Each of them is inserted into and stored in the memory 250.

Of course, the variable may be input through the key input unit 240, and the variable may be input by contacting the RFID tags 110, 120,..., Having the variable value as described above.

Subsequently, when the user contacts the RFID tags 110, 120,... With the RFID reader 210 and inputs a variable value by the key input unit 240 or the RFID tags 110, 120,..., The processor 220. Denotes a variable value input from the key input unit 240 or a variable value input by the RFID tags 110, 120, ... into each command program and sequentially stored in the memory 250.

When the series of robot operation programs set in the RFID tags 110, 120,... And the key input unit 240 are completed in the memory 250, the processor 220 drives the driver 260 to drive the motor 261, The robot is controlled by driving a driving device such as a speaker 262, a display unit 263 composed of LCD or LED, ..., and the like.

The external input unit 280 is an input device for upgrading or changing a command program stored in the program storage unit 230, and may be, for example, a connection slot of a memory in which the command program is stored, a connector for interfacing with a computer, and the like. have.

Therefore, the processor 220 upgrades or changes the instruction program stored in the program storage unit 230 as the instruction program input from the external input unit 280.

In some cases, the processor 220 may download a robot operation program pre-programmed from a computer through the external input unit 280, store the same in the memory 250, and then execute the RFID tag 110, 120 by the user. A program or a program downloaded from a computer can be selected and driven by the key input unit 240, and a plurality of robot driving programs are stored in the memory 250 so that a user can select a specific program to drive the robot. .

Of course, when the user sequentially selects a plurality of programs through the key input unit 240, the processor 220 continuously executes the stored programs to continuously execute the stored programs.

That is, the contents programmed in the past are stored in the memory 250, and subsequently executed in conjunction with a program to be input later, or immediately executed after the program currently input is executed so as to execute a program programmed in the past. By doing this, more diverse and complex actions can be executed.

When the RFID reader 210 is configured as an RFID reader / writer capable of recording a code in addition to reading a code from the RFID tags 110, 120,..., The changed code input from the external input unit 280 may be processed. 220 is input to control the RFID reader 210 to change the code to the chip (111, 121, ...) of the RFID tag (110, 120, ...).

For example, when an instruction program encounters an error, when an RFID tag having a code for a correction instruction is brought into contact with the RFID reader 210, the processor 220 reads and displays a robot operation program stored in the memory 250. And display through 263.

The user selects a sentence to be corrected while viewing the displayed robot motion program, and partially modifies the robot motion program by inputting corresponding RFID tags (110, 120, ...) and variable values.

Meanwhile, the present invention further includes an external chip slot 290, which copies the program programmed by the present invention to a separate device so that the device can operate. When the program code stored in the memory 250 is downloaded by inserting a chip having a compiler function, the chip mounted in the external chip slot 290 stores it in its own memory.

Then, if the user removes the chip from the external chip slot 290 and then mounted in the slot in another device, the device is capable of operating by executing the compiled program code stored in the memory.

This means that other languages can be operated without the user's knowledge of programming languages such as 'C' and 'Assembly.'

The present invention is to give a function that can be applied to a variety of devices by changing the command program and code values for selecting them suitable for industrial robots, plants, programmable household equipment, and the like.

2 is a diagram illustrating an implementation of a program according to the present invention, in which a training assembly robot avoids obstacles and arrives at a destination by contacting an RFID tag 110, 120, .. motor 261, The method of controlling the equipment constituting the robot, such as the speaker 262, the display unit 263 is shown.

First, when a user contacts the RFID reader 210 with an RFID tag for selecting an instruction to start a program, the code is read, and the processor 220 according to the read code, the instruction corresponding to the start from the program storage 230. After reading the program, the memory 250 stores the memory 250, and then touches an RFID to select a command for driving the left motor of the robot, and then inputs a variable value according to the rotation direction and the rotation speed through the key input unit 240. When the processor 220 reads the corresponding instruction program from the program storage unit 230 and then applies the variable value, the processor 220 stores it after the start instruction program stored in the memory 250.

Then, when the user contacts the RFID tag for receiving the detection signal from the ultrasonic sensor to the RFDI reader 210 and inputs the sensing distance which is a variable value through the key input unit 240, the processor 220 may also receive the corresponding command. The program is read from the program storage unit 230, the variable value is applied, and then stored after the driving command program of the left motor stored in the memory 250.

In this way, the sequential setting of the right motor, the ultrasonic sensor, etc. is continuously completed, and a command program for generating an alarm for notifying the arrival of the destination through the speaker 262 and the display unit 263 when the robot arrives at the destination is configured. Then, when finally contacting the RFID tag corresponding to the end instruction, the processor 220 will complete the configuration of the robot control program.

Therefore, the processor 220 drives the driving unit 260 by the robot control program stored in the memory 250 to operate the respective devices so that the robot arrives at the destination by the motor 264 and the sensor unit 270. .

As an example of a specific program,

if a = 1 motor = backward

if b = 2 motor = forward

If you program if (a = 1 & b = 2) motor = stop,

If the variables a and b are entered while the RFID tag for the if statement is in contact, the program for forward, backward and stop of the motor is simply completed.

The present invention is used not only for educational or industrial robots, but also for controlling a series of processes of a plant, so that programming can be easily performed without having specialized programming knowledge or expensive programming tools. According to the chemical input pipe and valve control, it is possible to easily program and control the type of chemical input, the dosage, and the timing of the chemical input by the RFID tag.
