Abstract

EVR 자동 조정장치 및 그 제어방법에 관한 것으로 자동으로 EVR 소자를 조정하기 위하여, 주제어부에 명령 데이타 및 기타 데이타가 입력되면 주제어부는 EVR 제어부로 데이타를 출력하고, 그 EVR 제어부는 입력데이타가 있는가를 판단하여 입력데이타가 있는 경우 1회 입력은 명령레지스터에, 2회 입력은 어드레스 레지스터에, 3회 입력은 데이타 레지스터에 저장한 후 상기 명령데이타를 분석하여 그에 따른 PWM 펄스를 EVR 소자로 출력한다.EVR automatic control device and its control method, in order to control EVR element automatically, when command data and other data are input to main control part, main control part outputs data to EVR control part, and the EVR control part judges whether there is input data. Thus, if there is input data, one input is stored in the command register, the second input is stored in the address register, and the third input is stored in the data register. The command data is analyzed, and the corresponding PWM pulse is output to the EVR device.

이 브이 알(EVR) 자동조정 장치 및 그 제어방법EVR automatic adjustment device and control method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명에 의한 EVR 자동조정 장치의 구성을 보이는 블럭도.2 is a block diagram showing the configuration of the automatic EVR adjustment apparatus according to the present invention.

Claims (3)

EVR 자동조정 장치에 있어서, 제어신호를 받아 그에 따른 EVR 조정데이타를 출격하는 EVR 제어부와, 조정명령 및 데이타등을 입력시키는 키입력부와, 상기 키입력부를 통해 입력된 명령 및 데이타에 따라 상기 EVR 제어부에 연결된 다수의 데이타선에 데이타를 출력하고, 제1프로토콜 선을 통해 송신시작 신호를 상기 EVR 제어부로 출력한 후, 상기 EVR 제어부로부터 제2프로토콜선을 통해 수신완료 신호를 받으면 상기 제1프로토콜선에 송신완료 신호를 출력하고 상기 데이타선에 출력되는 데이타를 완료하는 주제어부를 구비하는 것을 특징으로 하는 EVR 자동 조정장치.An EVR automatic adjustment device comprising: an EVR control unit for receiving a control signal and displaying the EVR adjustment data according to the control signal, a key input unit for inputting an adjustment command and data, and the EVR control unit according to the command and data inputted through the key input unit. Outputs data to a plurality of data lines connected to the controller; outputs a transmission start signal through the first protocol line to the EVR controller; and receives a reception completion signal from the EVR controller through the second protocol line; And a main control unit for outputting a transmission completion signal to and completing data output to the data line. 제1항에 있어서, 상기 데이타선은 8개의 선으로 되어 8비트 데이타를 출력 가능한 것을 특징으로 하는 EVR 자동 조정장치.2. The EVR automatic adjustment apparatus according to claim 1, wherein the data lines are eight lines capable of outputting 8-bit data. EVR 자동 조정장치의 제어방법에 있어서, 입력데이타가 있는가를 판단하여 입력데이타가 있는 경우에, 몇회 입력인지를 판단하여, 1회 입력인 경우, 명령 레지스터에 입력데이타를 저장하고 2회 입력인 경우, 어드레스 레지스터에 입력데이타를 저장하고 3회 입력인 경우 데이타 레지스터에 입력데이타를 저장하는 단계와, 상기 명령레지스터에 저장된 명령데이타를 읽어들여 "조정" 명령인지를 EVR 소자의 어드레스 데이타를 산출하여 그 데이타에 따라 PWM 펄스를 발생시켜 상기 EVR 소자로 출력하고 상기 입력데이타가 있는가를 판단하는 단계로 복귀하는 단계와, 상기 단계에서 "조정" 명령이 아닌 경우 "저장" 명령인지를 판단하여 "저장" 명령인 경우 PWM 분석루틴을 실행하여 데이타가 저장될 메모리 소자에 입력데이타를 저장하고 상기 입력데이타가 있는가를 판단하는 단계로 복귀하는 단계와, 상기 단계에서 "저장" 명령이 아닌 경우 "리세트" 명령인가를 판단하여 "리세트펄스"를 출력한 후, 상기 입력데이타가 있는가를 판단하는 단계로 복귀하고, 리세트 명령이 아닌 경우 상기 입력데이타가 있는가를 판단하는 단계로 복귀하는 단계를 구비하는 것을 특징으로 하는 EVR 자동 조정장치의 제어방법.In the control method of the EVR automatic adjustment device, it is determined whether there is input data, and when there is input data, it is judged how many inputs, and in case of one input, the input data is stored in the command register, and in case of two inputs, Storing the input data in the address register and storing the input data in the data register in the case of three inputs; and reading the command data stored in the command register and calculating the address data of the EVR element to determine whether it is an "adjust" command. According to the step of generating a PWM pulse and outputting to the EVR device and determining whether there is the input data, and if the step is not the "adjust" command in the step is determined that the "save" command is a "save" command In this case, the PWM analysis routine is executed to store the input data in the memory device where the data will be stored. Returns to the step of determining whether or not, and if it is not the "save" command in the step, outputs a "reset pulse" by determining whether it is a "reset" command and then returns to the step of determining whether there is the input data. And returning to the step of determining whether there is the input data if it is not a reset command. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
