Abstract

The invention relates to a photoelectric coupler radiation effect testing system and a testing method, which solves the problems of cumbersome process, few data points, time-consuming and labor-consuming, and low testing efficiency in the existing photoelectric coupler radiation effect testing method. The test system includes an optocoupler fixed module, a source meter measurement module and a PC control module; the optocoupler fixed module includes a circuit board, the circuit board is provided with a source meter input terminal interface and a socket, and the socket is provided with a photocoupler pin interface, It is used to fixedly connect the optocoupler, and the source meter measurement module is connected to the input port of the source meter to provide current or voltage to the optocoupler, and to measure the test data of the optocoupler in real time; the PC control module is connected through GPIB‑USB The conversion card is connected with the source meter measurement module, debugs and controls the source meter measurement module, and collects and records measurement data in real time. At the same time, the invention also provides a method for testing the radiation effect of the photoelectric coupler.

Description

technical field [0001] The invention relates to the field of space radiation effects, in particular to a radiation effect test system and a test method for a photoelectric coupler. Background technique [0002] Optocoupler is a common device used to transmit signals. It connects the output end with the input end by means of optical signals to achieve the conversion and transmission of signals between light-electricity-light. It usually connects the light-emitting source and light-receiving are packaged in the same closed case. The common light-emitting source is a light-emitting diode, which is powered on the input end to emit light, and the light intensity of different intensities is irradiated on the light receiver. The light receiver generates current due to the photoelectric effect, and the current is drawn out through the pin, and finally the purpose of isolating the input end and the output end is achieved. , due to the good isolation of optocouplers, they are widely ...
