Abstract
The invention provides an optoelectronic coupler performance detector. The optoelectronic coupler performance detector is characterized by comprising a 6V direct current power supply, a light emitting source detection display circuit and a light receptor detection display circuit. A common universal meter can only test the performance of an optoelectronic coupler. In order to accurately master the performance of the optoelectronic coupler, the optoelectronic coupler is required to be connected in a practical circuit for actual measurement, and once the performance of the optoelectronic coupler has a problem, the replacement of the optoelectronic coupler is quite inconvenient. The circuit of the optoelectronic coupler performance detector is fully made of common electronic components, so that the working state of the optoelectronic coupler can be directly observed, and the basic performance of the optoelectronic coupler can be accurately detected.
Description
Technical field
The invention belongs to electronic components test technical field, relate to a kind of photoelectrical coupler property detector.
Background technology
Photoelectrical coupler is that one uses electricity ~ light ~ power conversion device widely.It is made up of light emitting source and light-receiving device two parts, and it take light as media transmission electric signal.Light emitting source and light-receiving device are assembled in same airtight housing, isolate with transparent insulator each other.The pin of light emitting source is input end, and the pin of light-receiving device is output terminal, and common light emitting source is light emitting diode, and light-receiving device is phototriode.Its principle of work of phototriode is: make light emitting source luminous at photoelectrical coupler input end power up signal, the intensity of light depends on the size of exciting current, after this illumination is mapped to the light-receiving device be packaged together, photocurrent is created because of photoelectric effect, draw make-and-break signal by light-receiving device output terminal, so just achieve the conversion of electricity ~ light ~ electricity.
Use common multimeter can only the performance of simple test photoelectrical coupler, more accurately to understand the performance of photoelectrical coupler, just need photoelectrical coupler to receive in side circuit to survey, once the performance of photoelectrical coupler has problem, the lower replacing of weldering of being burn-on is got up and is extremely bothered.The circuit of photoelectrical coupler property detector of the present invention all uses normal electronics to be made, and it directly can observe the duty of photoelectrical coupler, and it can the key property of testing photoelectronic coupling mechanism more exactly.
Below describe that photoelectrical coupler property detector of the present invention is involved necessary in implementation process, guardian technique content in detail.
Summary of the invention
Goal of the invention and beneficial effect: use common multimeter can only the performance of simple test photoelectrical coupler, more accurately to understand the performance of photoelectrical coupler, just need photoelectrical coupler to receive in side circuit to survey, once the performance of photoelectrical coupler has problem, lower replacing of being burn-on is got up and is extremely bothered.The circuit of photoelectrical coupler property detector of the present invention all uses normal electronics to be made, and it directly can observe the duty of photoelectrical coupler, and it can the key property of testing photoelectronic coupling mechanism more exactly.
Circuit working principle: after photoelectrical coupler property detector connects 6V direct supply, if tested photoelectrical coupler G performance is intact, the resistance of linear potentiometer RP arranges suitably, and LED 1 and LED 2 should be lit simultaneously; If only have LED 1 to light, the light-receiving device side existing problems of tested photoelectrical coupler G are described or have damaged; The resistance of slow adjustment linear potentiometer RP, the luminosity of LED 1 and LED 2 should synchronously change.
Technical scheme: photoelectrical coupler property detector, it comprises 6V direct supply, light emitting source detection display circuit, light-receiving device detection display circuit, it is characterized in that:
