摘要
The purpose of this study is to identify the fault easily when repairing the switch stabilizer, and the fault diagnosis instrument of the extended stabilizer is used,The ultrasonic self-sensor (11) connects a filter (13) through a leaflet amplifier (12),Filter (13) resistance (R),(R) After composition with OP, connect single amplifier (14), resist (R),(R) Maximum amplifier (15) connecting diode (d) and operational amplifier (OP),The rear amplifier (14) is connected with the gain adjuster (16) and the horn (18) is connected with the analog switch (17),The frequency busy (19) and the busy selection switch (20) are connected to the analog switch (17) above, which is not affected by the outside world, and the failure state of the switch is quantitatively masteredTherefore, it is not only able to predict the aging phenomenon of switch stabilizer, but also a simple fault diagnosis instrument with excellent performance, which can be widely used in places such as preventive and servicing data, equipment diagnosis equipment, etc.
