[0030] Further, in order to realize signal isolation and avoid interference, the main controller and the relays are controlled through a driving circuit.
[0031] That is, the driving circuit comprises multiple optocouplers and multiple transistors, the input end of the optocoupler is connected with the main controller, the output end of the optocoupler is connected with the transistor, and the transistor is further connected with the relay; in order to facilitate signal transmission, RL0-T~RL7 are transmitted through connection terminals; in the drawings, one of the control signals RL4 is taken as an example, and the structures of the other control signals are similar, and will not be described herein.
[0032] The principle of the utility model is as follows: the microcontroller is used to control the relays through a driving circuit to switch different inductance, and the load connected with the outside is used to form a series LC resonance, when the optimal resonance point is adjusted, the circuit series impedance is minimum, and the working current of the ultrasonic cleaning generator is maximum, that is, the inductance controlled by the relay at this time is optimal.
[0033] The working process is as follows: when the one-key debugging button on the display panel is pressed, the microcontroller controls the 7 relays to act in turn, and simultaneously starts the ultrasonic wave, the microcontroller records and compares the current when the 7 relays act, the relay closed at the maximum current is the optimal gear for debugging, and the ultrasonic cleaning generator works normally.
