제4도는 텔리미터엔코우더의 동작상태를 나타낸 것으로, 이를 참조하면서 본 발명의 작용을 설명하면 다음과 같다. 센터의 지시에 따라 가입자정합장치(4)로부터 미터읽기요구신호가 제공되면 인터페이스부(16) 및 제어부(15)를 통하여 텔리미터엔코더 (12)로 정보송출신호(CMD)가 제공된다. 이와 같이 정보송출신호(CMD)가 텔리미터인코더(12)로 입력되면(단계31), 콘트롤러(26)는 미터고정정보부(19)와 BCD카운터 (20)를 인에이블(enable)시킨다.Figure 4 shows the operating state of the telemeter encoder, the operation of the present invention will be described with reference to the following. When the meter read request signal is provided from the subscriber matching device 4 according to the instruction of the center, the information transmission signal CMD is provided to the telemeter encoder 12 through the interface unit 16 and the control unit 15. When the information transmission signal CMD is input to the telemeter encoder 12 (step 31), the controller 26 enables the meter fixing information unit 19 and the BCD counter 20.

따라서, 미터고정정보와 BCD카운터(20)로부터 제공되는 계수정보가 버퍼 (22)에 저장된다. 이때, BCD카운터(20)의 계수정보는 적산된다. 이어, 콘트롤러(26)는 패리티/포맷발생부(23)를 동작시켜 버퍼(22)로부터 제공되는 데이타에 피리티비트를 추가하고 데이타의 형태를 규정된 전송데이타형태로 만든다(단계32, 33). 이때, 버퍼(22)로부터 패리티/포맷발생부(23)로의 데이타전달은 디코더(21)의 출력에 의해 제어된다. 디코더(21)는 BCD카운터(20)의 계수정보를 해독하여 버퍼(22)에 저장된 정보를 선택하여 출력하도록 하는 정보선택신호를 버퍼(22)로 제공함으로써 버퍼(22)에 저장된 정보가 선택적으로 패리티/포맷발생부(23)로 제공된다.Therefore, the meter fixing information and the coefficient information provided from the BCD counter 20 are stored in the buffer 22. At this time, the count information of the BCD counter 20 is integrated. Subsequently, the controller 26 operates the parity / format generator 23 to add a pyritic bit to the data provided from the buffer 22 and to form the data in the form of prescribed transmission data (steps 32 and 33). . At this time, data transfer from the buffer 22 to the parity / format generator 23 is controlled by the output of the decoder 21. The decoder 21 decodes the coefficient information of the BCD counter 20 and provides the buffer 22 with an information selection signal for selecting and outputting the information stored in the buffer 22 to selectively store the information stored in the buffer 22. The parity / format generator 23 is provided.

다음에는 패리티/포맷발생부(23)의 정보를 “본문개시”“미터고정정보”“적산치”“본문완료”의 순서로 시프트레지스터(24)로 입력시키고(단계34), 시프트레지스터(24)에 기억된 정보는 시작신호인 start비트를 출력시킨후(단계35), 계량치를 8비트로 가입자정합장치를 통해 출력시킨 다음(단계36), 종료신호인 stop비트를 출력한다(단계37).Next, the information of the parity / format generator 23 is input to the shift register 24 in the order of "body start", "meter fixation information", "integrated value" and "body completion" (step 34), and the shift register 24 ), The start bit, which is a start signal, is output (step 35), the meter value is output through the subscriber matching device as 8 bits (step 36), and then the stop bit, which is an end signal, is output (step 37).

계량치의 출력이 완료되었는가를 확인하여(단계38), 출력이 진행중이면 계속하도록 하고, 완료되었으면 최초의 상태로 귀환된다. 따라서 본 발명을 자동검침시스템의 원격계량장치에서 디지탈 논리부분을 하나의 칩으로 형성하면서 그 동작이 안정되며 빠른속도로 진행되도록 함으로써 설치비와 유지비와 유지비가 적게 소요되면서 작동검침의 기능이 안정되도록 한 것임을 알 수 있다.It is checked whether the output of the weighing value is completed (step 38), so that the output is continued if it is in progress, and when it is completed, it is returned to the initial state. Therefore, the present invention forms a digital logic part in the remote metering device of the automatic meter reading system to form a single chip so that the operation is stable and proceeds at a high speed so that the function of the meter reading is stabilized while the installation cost, maintenance cost and maintenance cost are reduced. It can be seen that.
