이하에서, 본 발명에 따른 진동발생장치의 구동모터(16)를 제어하는 방법을 상세히 설명한다.Hereinafter, a method of controlling the driving motor 16 of the vibration generating device according to the present invention will be described in detail.

먼저, 시뮬레이션할 모의진동데이터를 입력수단(11)을 통해 입력하고, 이 입력된 진동데이터를 제어수단(13)에서 제어신호로 변환한 후 시간에 따라 순차적으로 펄스발생수단(14)에 출력한다. 한편, 지진과 같은 진동파는 단시간에 (예컨대 1초, 더욱 정확하게는 0.02초 이하) 변동되기 때문에 진동데이터도 이에 맞추어 1초 이하를 주기로 진동하도록 설정된다.First, the simulation vibration data to be simulated is input through the input means 11, and the input vibration data is converted into the control signal by the control means 13, and then output to the pulse generating means 14 sequentially in time. . On the other hand, since vibration waves such as earthquakes fluctuate in a short time (for example, 1 second, more precisely, 0.02 seconds or less), the vibration data is set to vibrate at a rate of 1 second or less accordingly.

펄스발생수단(14)에서는, 제어수단(13)으로부터의 제어신호가 프로그래머블 입출력 확장소자(23)와 프로그래머블 타이머/카운터(24)로 입력되는데, 이 때 어드레스 디코더(21)에 의해 제어신호중 구동모터(16)의 작동방향에 대한 제어신호(S0)는 프로그래머블 입출력 확장소자(23)로 그리고 구동모터(16)의 작동시간에 대한 제어신호(ST)는 프로그래머블 타이머/카운터(24)로 입력된다. 프로그래머블 입출력 확장소자(23)로 입력된 구동모터(16)의 작동방향에 대한 제어신호(S0)중 구동모터의 정지펄스(C0)는 프로그래머블 입출력 확장소자(23)로부터 콘트롤러(15)로 직접 출력되고 시계방향 또는 반시계방향으로의 작동신호(C0')는 프로그래머블 입출력 확장소자(23)로부터 프로그래머블 타이머/카운터(24)로 출력된다. 프로그래머블 타이머/카운터(24)는 제어수단(13)으로부터 입력되는 구동모터(16)의 작동시간에 대한 제어신호(ST)에 따라 작동시간을 카운트하고 그리고 오실레이터(25)로부터 입력되는 기본값을 기준으로 프로그래머블 입출력 확장소자(23)로부터 입력되는 구동모터(16)의 작동신호들(C1, C2)을 분주하여 카운트신호(SC)와 그리고 시계방향으로의 작동신호(C1) 또는 반시계방향으로의 작동신호(C2)를 비교연산자(26)로 출력한다. 비교연산자(26)는 카운트신호(SC)와 분주된 작동신호(C1, C2)를 비교연산하여 시계방향으로의 구동펄스 도는 반시계방향으로의 구동펄스(CW 또는 CCW)를 콘트롤러(15)로 출력한다. 한편, 오실레이터(25)는 프로그래머블 입출력 확장소자(23)의 출력신호(C0')중 시계방향으로의 작동신호(C1)와 반시계방향으로의 작동신호(C2)를 분주하는 기본값을 프로그래머블 타이머/카운터(24)로 출력한다.In the pulse generating means 14, the control signal from the control means 13 is input to the programmable input / output expansion element 23 and the programmable timer / counter 24, at which time the drive motor of the control signal by the address decoder 21. The control signal S0 for the operation direction of 16 is input to the programmable input / output expansion element 23 and the control signal ST for the operation time of the drive motor 16 is input to the programmable timer / counter 24. The stop pulse C0 of the driving motor is directly output from the programmable input / output expansion element 23 to the controller 15 among the control signals S0 for the operation direction of the driving motor 16 input to the programmable input / output expansion element 23. And the operation signal C0 'in the clockwise or counterclockwise direction is output from the programmable input / output expansion element 23 to the programmable timer / counter 24. The programmable timer / counter 24 counts the operation time according to the control signal ST for the operation time of the drive motor 16 input from the control means 13 and based on the default value input from the oscillator 25. The operation signals C1 and C2 of the driving motor 16 input from the programmable input / output expansion element 23 are divided to operate the count signal SC and the operation signal C1 clockwise or counterclockwise operation. The signal C2 is output to the comparison operator 26. The comparison operator 26 compares the count signal SC with the divided operation signals C1 and C2 and transfers the driving pulse clockwise or the counterclockwise driving pulse CW or CCW to the controller 15. Output On the other hand, the oscillator 25 divides the operation signal C1 in the clockwise direction and the operation signal C2 in the counterclockwise direction among the output signals C0 'of the programmable input / output expansion element 23 as a programmable timer /. Output to the counter 24.

따라서, 펄스발생수단(13)으로부터는 구동모터의 정지펄스(C0) 또는 시계방향구동펄스(CW) 또는 반시계방향구동펄스(CCW)가 콘트롤러(15)에 출력되고, 콘트롤러(15)는 상기 세 신호중 입력되는 펄스신호에 따라 구동모터(16)를 정지 또는 구동시키게 되는데, 대략 1초 이하의 시간간격으로 더 정확히는 0.02초 이하의 시간간격으로 구동신호들(C0, CW, CCW)이 바뀌게 되어, 구동모터(16)에 결합되어 있는 진동대(17)가 모의진동데이터에 따라 진동하게 된다.Therefore, from the pulse generating means 13, the stop pulse C0 or the clockwise drive pulse CW or the counterclockwise drive pulse CCW of the drive motor is output to the controller 15. The driving motor 16 is stopped or driven according to the pulse signal input among the three signals, and the driving signals C0, CW, and CCW are changed at a time interval of 0.02 seconds or less at a time interval of approximately 1 second or less. The shaking table 17 coupled to the driving motor 16 vibrates according to the simulation vibration data.

From The operation signals C1 and C2 of the driving motor 16 inputted from the programmable input / output expansion element 23 are divided based on the inputted default value, thereby counting the signal SC and the operation signal C1 in the clockwise direction, or The operation signal C2 in the counterclockwise direction is output to the comparison operator 26. The comparison operator 26 compares the count signal SC and the divided operation signals C1 and C2 to drive in the clockwise direction. The driving pulse CW or CCW in the counterclockwise direction is output to the controller 15, but the oscillator 25 is a clockwise operation signal (C0 ') of the output signal C0' of the programmable input / output expansion element 23. A pulse generating step of outputting, to the programmable timer / counter 24, a default value for dividing C1) and the operation signal C2 in the counterclockwise direction; And 상기 콘트롤러(15)가 상기 펄스발생수단(14)으로부터 소정 시간간격으로 출력되는 정지펄스(C0), 시계방향구동펄스(CW) 또는 반시계방향구동펄스(CCW)에 따라 구동모터(16)를 구동하는 단계를 구비하여,The controller 15 drives the drive motor 16 according to the stop pulse C0, the clockwise drive pulse CW or the counterclockwise drive pulse CCW output from the pulse generating means 14 at a predetermined time interval. Driving step, 구동모터(16)에 결합되어 있는 진동대(17)가 모의진동데이터에 따라 진동하게 되는 것을 특징으로 하는 진동발생장치의 구동모터(16)를 제어하는 방법.Method for controlling the drive motor (16) of the vibration generating device characterized in that the shaking table (17) coupled to the drive motor (16) is vibrated according to the simulation vibration data.
