Design Of Control Circuit Of Super Lizer

In recent years，because People’s living standards continuously improve，and requirements ofbeauty and health increasing too. For some tumors, skin diseases, tattoo, stain removal andskin care. For this reason, laser therapy as a new treatment has been rapid development, it isnot only effective, but side effects are small.Papers in the first generation of LED display light therapy instrument on the basisdeveloped a second generation LCD display targeted radiation treatment in the field designedlow-power light therapy instrument. suitable for clinical radiation therapy or physical therapyhome health-care.Thesis for the following work Compared:1．Using Customized Segment LCD VT066replace the LED digital display, while achievinga power display, time setting display, mode switch display, the system date display.Interface is easy to operate, intuitive meet user requirements.2． Zero-crossing detection circuit by use of zero-crossing signal detected by themicroprocessor, computing, according to the parameters established by the output power,the timer microprocessor-controlled timer to trigger SCR to achieve digital control ofphase thyristor trigger.3． For the whole machine’s hardware design and software programming, and conductedon-line debuggingRays Therapy Equipment Co., Ltd by Bomu put on the market, well received by customers.
