摘要
文章介绍了医用眼科激光治疗仪控制器的设计。采用半导体泵浦Nd:YAG激光器,激光器有脉冲、连续两种工作方式。工作于脉冲方式时,单片机定时器产生脉冲控制激光器的工作频率;控制器使用数模转换器产生电压信号,驱动功率控制模块来控制激光器的功率;使用彩色触控液晶模组设计人机界面,通过触控屏来选择工作方式和设置工作参数;对关键电路进行了分析说明,给出了程序设计流程图。
The design of the medical treatment of ophthalmic laser instrument controller is described in this paper. It uses the semiconductor pumped Nd： YAG laser which has two working modes： pulse mode and continuous mode. Working in pulse mode, the microcontroller＇s timer controls the laser pulse frequency. The controller uses the DAC （Digital-to-Analog Converter） to produce a voltage signal to drive the power control module to control the laser energy. The color LCD（Liquid Crystal Display） with touch-screen module is used to design the interface. Through the touch screen, the working mode and operating parameters are set. The circuit of system is introduced, and the program flow chart is given in the last.
