본 발명은 승용차 안전벨트 자동이송 시스템의 상태진단에 관한 것으로, 특히 마이크로프로세서를 이용하여 비동기 직렬상태신호를 전송받아 그 상태를 발광다이오드로 표시하여주는 승용차 안전벨트 전자식 조정기의 상태진단방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a state diagnosis of an automobile seat belt automatic transfer system. More particularly, the present invention relates to a state diagnosis method of an electronic regulator of a car seat belt, in which an asynchronous serial state signal is received using a microprocessor and the state thereof is indicated by a light emitting diode. .

일반적으로 승용차 전장품의 고기능화 및 저소비전력화에 따라 승용차 안전벨트 자동이송 시스템이 릴레이조정방법에서 마이크로프로세서를 이용한 전자식 조정방법으로 바뀌어져가므로 안전벨트 전자식 조정기의 상태진단기능이 요구되었다. 그런데 이와 같은 상태진단기능은 승용차 안전벨트 조정기 자체에 내장하여 동작하도록 할 수 있으나, 그렇게되면 제품자체의 차지면적 및 소비전력이 커지게되어 승용차 전장품으로서의 가치를 저하시키게 되는 문제점이 있었다.In general, according to the high functionality and low power consumption of passenger electronics, the automatic seatbelt automatic transfer system is changed from a relay adjustment method to an electronic adjustment method using a microprocessor. By the way, such a state diagnosis function can be built in the car seat belt regulator itself to operate, but if there is a problem that the charge area and power consumption of the product itself is increased, which degrades the value as a passenger electronics.

본 발명은 이와 같은 문제점을 감안하여 마이크로프로세서를 이용하여, 안전벨트 자동이송 시스템으로부터 비동기직렬상태신호를 전송받아 그 상태를 발광다이오드로 표시함으로써 안전벨트 시스템을 진단히하며, 또한 승용차 안전벨트 시스템이 정상으로 동작하고 있으면 상태진단 기능이 불필요하게 되므로 상기 안전벨트시스템의 진단기능을 별도의 휴대용으로 제작하여 제품자체의 차지면적 및 소비전력을 줄이도록한 승용차 안전벨트 전자식 조정기의 상태진단 방법을 창안한 것으로, 이하 첨부한 도면에 의해 상세히 설명하면 다음과 같다.In view of the above problems, the present invention diagnoses a seat belt system by receiving an asynchronous serial state signal from an automatic seat belt automatic transfer system and displaying the state with a light emitting diode using a microprocessor. If it is operating normally, the status diagnosis function is not necessary. Therefore, the diagnostic function of the seat belt system was manufactured as a separate portable device, and the method for diagnosing the state of the electronic seat controller of the passenger car seat belt was designed to reduce the charge area and power consumption of the product itself. When described in detail with reference to the accompanying drawings as follows.

제1도는 본 발명 승용차 안전벨트 전자식 조정기의 상태진단에 대한 블럭도로서 이에 도시한 바와 같이, 승용차 안전벨트 전자식 조정기(5)에 콘넥터(6)를 접속하여, 파워공급선(POWER), 그라운드선(GND)을 통해 정전압회로(1)에 파워를 인출하고, 직렬신호요청선(DRQ), 직렬신호전송선(TXD)을 통해 마이크로프로세서(3)와 데이터를 교환하며, 스위치(2)를 통해 상기 마이크로프로세서(3)에 상기 승용차 안전벨트 전자식 조정기(5)의 상태진단을 요구하여 표시부(4)를 통해 점검되게 상태진단기(7)를 구성한다.FIG. 1 is a block diagram of the state diagnosis of the seat belt electronic regulator of the present invention, as shown in FIG. 1, by connecting the connector 6 to the seat belt electronic regulator 5 of the passenger car. Draws power to the constant voltage circuit 1 through GND), exchanges data with the microprocessor 3 through a serial signal request line DRQ, and a serial signal transmission line TXD, and switches the micro The state diagnostic device 7 is configured to be checked by the display unit 4 by requesting the processor 3 to diagnose the state of the passenger car seat belt electronic regulator 5.

제2도는 본 발명 비동기 직렬신호의 전송형태도로서 이에 도시한 바와 같이, 상기 승용차안전벨트 전자식 조정기(5)로부터 직렬신호전송선(TXD)을 통해 마이크로프로세서(3)에 인가되는 비동기 직렬신호의 전송형태를 나타낸 것이다.2 is a diagram of the transmission of the asynchronous serial signal of the present invention, as shown here, and the transmission of the asynchronous serial signal applied to the microprocessor 3 from the passenger car seat belt electronic regulator 5 through the serial signal transmission line TXD. The form is shown.

이와 같이 구성된 본 발명은 제1도에 도시한 바와 같이, 상태진단요구스위치(2)가 온되면 마이크로프로세서(3)로부터 직렬신호요청선(DRQ)을 통해 승용차 안전벨트 전자식 조정기(5)에 직렬신호요청을 한다.As shown in FIG. 1, when the state diagnosis request switch 2 is turned on, the present invention configured as described above is serially connected to the passenger car seat belt electronic regulator 5 through the serial signal request line DRQ from the microprocessor 3 when the state diagnosis request switch 2 is turned on. Make a signal request.

이때 승용차 안전벨트 전자식 조정기(5)에서는 제3도에 도시한 바와 같이, 프로그램 초기화를 수행한 후 안전벨트 조정동작을 처리하면서 신호전송요청을 판별하여 비요청이면 상기 안전벨트조정동작을 반복하며, 요청이면 상태신호를 내부 기억장치에 저항한 후 직렬신호전송선(TXD)을 통해 제2도에 도시한 바와 같은 데이터형태로 마이크로프로세서(3)에 전송한다.In this case, as shown in FIG. 3, the electronic seat belt electronic regulator 5 of the passenger car determines the signal transmission request while processing the seat belt adjustment operation after initializing the program, and repeats the seat belt adjustment operation if it is not requested. Upon request, the status signal is resisted to the internal memory and then transmitted to the microprocessor 3 in the form of data as shown in FIG. 2 via the serial signal transmission line TXD.

여기서 상태진단에 대한 신호흐름도인 제4도에 의해 상태진단 기능을 설명하면 다음과 같다.Here, the state diagnosis function will be described with reference to FIG. 4, which is a signal flow diagram for state diagnosis.

우선 상태진단기(7)가 콘넥터(6)에 의해 승용차 안전벨트 전자식 조정기(5)에 접속되면, 승용차 안전벨트 전자식 조정기(5)로부터 정전압회로(1)를 통해 전원을 공급받게 되고, 내부타이머 입출력포트를 지정하는 초기화를 수행한 후 상태진단을 요구하는 스위치(2)의 온상태를 감지할 때까지 스위치(2)의 온상태를 점검한다.First, when the state diagnosis device 7 is connected to the passenger car seat belt electronic regulator 5 by the connector 6, power is supplied from the passenger car seat belt electronic regulator 5 through the constant voltage circuit 1, and the internal timer input / output After performing initialization to designate the port, the on state of the switch 2 is checked until the on state of the switch 2 requiring the state diagnosis is detected.

이와 같이 하여 상태진단을 요구하는 스위치(2)가 온되면, 직렬신호요청선(DRQ)을 통해 상기와 같이 승용차 안전벨트 전자식 조정기(5)에 직렬신호 요청을 하면서 내부타이머를 가동시키고, 직렬신호전송선(TXD)을 통해 제2도에 도시한 바와 같은 전송시작비트의 입력을 기다린다. 이때 전송시작비트가 소정시간, 일예로 0.1초가 될 때까지 전송되지 않거나 각 전송신호 블럭간의 시작비트 및 전송 끝비트가 전송되지 않으면 표시부(4)를 통해 전송사고를 표시하여 주고, 소정지연시간, 일예로 0.5초의 지연시간후에 다시 직렬신호요청을 한다.When the switch 2 for requesting the status diagnosis is turned on in this way, the internal timer is operated while making a serial signal request to the passenger car seat belt electronic regulator 5 as described above through the serial signal request line DRQ. The transmission line TXD waits for the input of the transmission start bit as shown in FIG. At this time, if the transmission start bit is not transmitted until a predetermined time, for example, 0.1 seconds, or if the start bit and the transmission end bit between the respective transmission signal blocks are not transmitted, a transmission accident is displayed through the display unit 4, and a predetermined delay time, For example, a serial signal request is made again after a delay of 0.5 seconds.

이후 전송이 올바르게 되면 이의 전송데이터를 내부기억장치로 이동한 후 신호의 정상수신인가를 판별하여 비정상수신이면 상기와 같이 표시부(4)를 통해 전송사고를 표시하며, 정상수신으로 되면 수신신호를 처리한 후 각각의 안전벨트 이송해제모드, 안전벨트 이송잠김모드, 안전벨트 이송해제위치, 안전벨트 이송감김위치, 자동차주행중, 시동스위치, 차도어잠김, 후진기어, 벨트이송 솔레노이드, 벨트이송 타임아우트, 대각벨트매지않음, 무릅벨트매지않음, 미연방자동차 안전규격의 경보등에 대한 상태를 표시부(7)를 통해 표시한다. 이의 처리가 완료되면 처음으로 리턴하여 다음 신호를 처리한다.After that, if the transmission is correct, the transmission data is moved to the internal storage device, and then the signal is determined to be normal. If the signal is abnormal, the transmission is displayed through the display unit 4 as above. Each seat belt release mode, seat belt transfer lock mode, seat belt transfer release position, seat belt transfer winding position, car driving, start switch, car door lock, reverse gear, belt transfer solenoid, belt transfer timeout, Displays the status of the diagonal belt not attached, the non-elbow belt, the alarm of the US Federal Motor Vehicle Safety Standard through the display unit (7). When its processing is completed, it returns to the first and processes the next signal.

이상에서 상세히 설명한 바와 같이 본 발명은 승용차 안전벨트 자동이송시스템의 이상동작시 그의 상태를 표시하여 주므로 이상동작시 또는 고장시에 애프트서비스센타 등에서 신속한 처리 및 고장해결업무를 지원해 줄 수 있는 효과가 있다.As described in detail above, the present invention displays its state during abnormal operation of a passenger car safety belt automatic transfer system, and thus has an effect of supporting rapid processing and troubleshooting at an after-service center during abnormal operation or failure. have.
