One end of the output end of the optical coupling relay A is grounded, and the other end of the output end of the optical coupling relay A is serially connected with a current limiting measuring resistor R2, a work indicator lamp D1 and a metal-oxide-semiconductor field-effect transistor (MOSFET) tube Q2 with a high voltage resistance value.
Description
Technical field
The utility model relates to a kind of light coupling relay mass detecting instrument, belongs to integrated circuit and electronic devices and components detection range.
Background technology
Light coupling relay is a kind of of solid-state relay, and general relay all is a mechanical contact, crosses coil by galvanization and becomes magnetic magnet adhesive contact, the state thereby control is opened the light; And the light coupling relay principle of work is similar to optocoupler, and light coupling relay is a semiconductor relay, and the light emitting diode conducting ends, and the reception diode conducting ends; Can not scrap because of aging, frequent switch, its life-span almost is unlimited, so light coupling relay is applicable to the field that needs switch repeatedly; In the occasion that a large amount of parallel connections of needs are used, light coupling relay is not done detection just be applied in the circuit, if one of them light coupling relay has been gone bad; It is that path loss is bad that circuit is difficult to find, so, before the application; Need the quality of light coupling relay be detected, because it is light coupling relay is composite semiconductor components and parts, existing like instrument such as multimeters; All can not do such detection, especially during mass detection, at this moment detect with regard to the corresponding special measurement instrument of needs.
Summary of the invention
The utility model relates to a kind of light coupling relay mass detecting instrument, to realize quality testing and the evaluation to light coupling relay.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: light coupling relay A fixing through special-purpose seat, and input end inserts the 5V power supply, through the R1 current limliting; The input control end of the light coupling relay of flowing through A; And then insert triode Q1, by the Push And Release of beating of triode Q1 control light coupling relay A, the base stage of triode Q1 is controlled by single-chip microcomputer.The output terminal one end ground connection of light coupling relay A, current limliting measuring resistance R2 of other end serial connection, the MOSFET pipe Q2 of a relay indicating light D1 and a high withstand voltage notices that the last voltage that connects of Q2 is a high-voltage value.
When measuring the leakage electric current of light coupling relay A, input end triode Q1 outage, not input, at this moment, relay indicating light D1 goes out, and surveys the voltage on C1, the C2 measuring resistance R2, because the resistance of R2 is known, it misses electric current I=U2/R2.
When measuring light coupling relay A conducting resistance, input end triode Q1 powers up, and measures light coupling relay A and starts working; Simultaneously, relay indicating light D1 is bright, surveys the voltage on C1, the C2 measuring resistance R2 earlier; And then survey the voltage on C2, the C3 optocoupler, because output current is equal, promptly
U2/R2=Ua/Rx
Can draw thus:
Rx=(Ua*R2)/U2
Thereby know the conducting resistance of light coupling relay.
Above control procedure is controlled by single-chip microcomputer automatically, shows measurement result through the LCD liquid crystal display, and the whole operation process is easy; Simultaneously, can report to the police, guarantee the middle safety that light coupling relay is being used substandard product; Reliably, improved the reliability that electronics produces device greatly.
