When performing the function, according to the selective conduction of the infrared light emitting diodes (LED 1 ~ LED n ) of the light emitting unit 1, the phototransistors (PTR 1 ~ PTR n ) of the light receiving unit 2 is correspondingly conducted to perform a normal function. When an abnormality occurs in any one of the infrared light emitting diodes LED 1 to LED n of the light emitting unit 1 or the phototransistors PTR 1 to PTR n of the light receiving unit 2 and the normal touch function is not performed. Screen part to confirm to the user ( 3) and an abnormality occurs in any one of the infrared light emitting diodes LED 1 to LED n of the light emitting unit 1 and the phototransistors PTR 1 to PTR n of the light receiving unit 2 to perform a normal touch function. If not, the display unit 4 is configured to display the positions of the infrared light emitting diodes LED 1 to LED n and the phototransistors PTR 1 to PTR n that have occurred.
이와 같이 구성한 본 발명의 모니터 터치기능 고장감지장치의 동작과정과 동작방법 및 작용, 효과를 본 발명의 모니터 터치기능 고장감지시 신호흐름도인 제3도를 참조하여 상세히 설명하면 다음과 같다.An operation process, an operation method, an operation, and an effect of the monitor touch function failure detecting device of the present invention configured as described above will be described in detail with reference to FIG.
모니터링 부분에 터치기능 영역을 설정하고 사용자가 그 설정된 터치영역을 누르면 발광부(1)의 적외선 발광다이오드(LED1~LEDn)는 선택적으로 도통되어 적외선 빛을 발생하고 이에따라 수광부(2)의 광트랜지스터는 상기 적외선 발광다이오드(LED1~LEDn)의 선택적인 도통에 대응되게 선택적으로 도통되어 정상적인 터치기능을 수행한다.When the touch function area is set in the monitoring part and the user presses the set touch area, the infrared light emitting diodes (LED 1 to LED n ) of the light emitting part 1 are selectively turned on to generate infrared light and accordingly the light of the light receiving part 2 is applied. The transistor is selectively conductive to correspond to the selective conduction of the infrared light emitting diodes LED1 to LED n to perform a normal touch function.
한편 상기 발광부(1)의 적외선 발광다이오드(LED1~LEDn) 또는 수광부(2)의 광트랜지스터(PTR1~PTRn)에 이상이 발생하여 정상적인 터치기능 수행이 불가능할때 고장부의를 진단을 설명하면 다음과 같다.On the other hand, when an abnormality occurs in the infrared light emitting diodes LED 1 to LED n of the light emitting unit 1 or the phototransistors PTR 1 to PTR n of the light receiving unit 2, and thus it is impossible to perform a normal touch function, the fault unit is diagnosed. The explanation is as follows.
터치기능 키가 인가되면 모니터링 장치 외곽에 배치되어 있는 터치기능용 발광부(1)의 적외선 발광다이오드(LED1~LEDn)를 동작시키고 그 맞은편에 있는 수광부(2)의 광트랜지스터(PTR1~PTRn)의 동작여부를 감지하여 고장이 발견되지 않을 경우 다른 터치용 소자를 검사하는 한편 상기 발생부(1)의 적외선 발광다이오드(LED1~LEDn)를 선택적으로 도통시켜 그 적외선 발광다이오드(LED1~LEDn)가 도통되지 않으면 발광부(1)의 고장상태를 인식하고 이상이 발생한 적외선 발광다이오드(LED1~LEDn)를 표시부(4)를 통해 사용자에게 인식시키고 상기 발광부(1)의 적외선 발광다이오드(LED1~LEDn)가 정상적인 동작을 할 경우 상기 적외선 발광다이오드(LED1~LEDn)의 선택적인 도통에 따라 그에 대응하는 수광부(2)의 광트랜지스터(PTR1~PTRn)의 도통상태를 판단하여 그 결과를 표시부(4)를 통해 사용자에게 인식시키고 그 수광부(2)의 가 광트랜지스터(LED1~LEDn) 모두 정상이면 다른 터치용 소자의 이상유무를 확인하여 이를 표시부(4)로서 사용자에게 인식시킨다.When the touch function key is applied, the infrared light emitting diodes LED 1 to LED n of the touch function light emitting unit 1 disposed outside the monitoring device are operated, and the phototransistor PTR 1 of the light receiving unit 2 opposite to the light emitting unit 1 is operated. If no failure is found by detecting the operation of ~ PTR n ), another touch element is inspected, and the infrared light emitting diodes (LED 1 to LED n ) of the generating unit 1 are selectively conductively connected to the infrared light emitting diodes. If the LED 1 to LED n is not conducting, the fault state of the light emitting unit 1 is recognized, and the infrared light emitting diode LED 1 to LED n having an abnormality is recognized by the user through the display unit 4 and the light emitting unit ( When the infrared light emitting diodes LED 1 to LED n of 1 ) operate normally, the phototransistors PTR 1 to light receivers 2 corresponding to the selective conduction of the infrared light emitting diodes LED 1 to LED n are applied. to determine the conductive state of PTR n) The results through the display unit (4) recognizes the user and the light receiving portion (2) is a phototransistor (LED 1 ~ LED n), both recognized by the user normally is to determine the presence of error in the other touch devices for this, as a display portion (4) of Let's do it.
결국 터치기능 수행시 발광부(1)의 적외선 발광다이오드(LED1~LEDn) 또는 수광부(2)의 광트랜지스터(PTR1~PTRn)에 이상이 발생하면 발광부(1)의 적외선 발광다이오드(LED1~LEDn)을 순차적으로 도통시켜 이상유무를 감지하고 정상상태이면 그에 대응하는 수광부(2)의 광트랜지스터(PTR1~PTRn)의 동작상태를 판단하여 이상유무를 감지하여 이상발생시 이를 표시부(4)를 통해 고장부위를 표시하고 모두 정상상태이면 다른 터치용 소자를 감지한다.As a result, when an error occurs in the infrared light emitting diodes LED 1 to LED n of the light emitting unit 1 or the phototransistors PTR 1 to PTR n of the light receiving unit 2 when the touch function is performed, the infrared light emitting diode of the light emitting unit 1 is generated. (LED 1 ~ LED n ) is sequentially connected to detect the presence of abnormality, and if it is in a normal state, the operation state of the phototransistor (PTR 1 ~ PTR n ) of the light receiving unit 2 corresponding to it detects the presence of abnormality, This indicates the failure site through the display unit 4 and detects another touch element when all are in a normal state.
상기와 같은 방법으로 동작하는 본 발명의 모니터 터치되는 고장감지장치는 모니터링 장치 외막에 위치한 터치기능용 적외선 발광다이오드와 수광용 광트랜지스터 고장시 이를 확인하여 고장이 발생한 부분의 적외선 발광다이오드와 광트랜지스터를 표시부를 통해 사용자에게 인식시키므로 고장발생시 정확한 위치를 알수 있어 모니터 터치기능 고장감지장치의 성능을 향상하는 효과가 있다.The monitor touch failure detection device of the present invention operating in the above-described manner detects the failure of a touch function infrared light emitting diode and a light receiving phototransistor located on the outer membrane of the monitoring device, and detects the infrared light emitting diode and the phototransistor of the portion where the failure occurs. Because it recognizes to the user through the display, it is possible to know the exact position when a failure occurs, thereby improving the performance of the monitor touch function failure detection device.
