摘要
根据双波长激光治疗仪的功能需求和便于携带的特点,完成了双波长激光治疗仪控制系统的设计,包括硬件设计和软件设计。硬件部分主要完成了电源模块、主控制器模块、激光器驱动模块和TEC温控模块等设计,软件部分主要完成APP人机交互模块的设计和控制程序的编写。采用基于ARM Cortex-M3内核的STM32F103RCT6芯片作为主控芯片,以锂电池组作为供电系统的核心模块,采用恒流方式驱动激光器,并以智能手机作为人机交互的载体,通过开发应用程序APP完成治疗仪的参数设置。对相关模块进行了测试,结果表明,激光器驱动模块的输出电流稳定度在1%以下,实际输出脉宽与目标脉宽的最大偏差率在1%以下,实际输出功率与目标功率的最大偏差率在5%以下。
According to the functional requirements and portable features of dual-wavelength laser therapeutic instrument,the control system of dual-wavelength laser therapeutic instrument is designed,including hardware design and software design.In hardware part,the power module,the main controller module,the laser driver module and the TEC temperature control module are designed.In software part,the human-computer interaction module and the control program are designed.The STM32 F103 RCT6 chip based on ARM Cortex-M3 core is used as the main control chip,the lithium battery group is used as the core module of the power supply system,the constant current mode is used to drive the lasers,the smart phone is used as the carrier of human-computer interaction,and the parameter setting of the therapeutic instrument is completed through the development of application APP.The results show that the output current stability of the laser driver module is less than 1%,the maximum deviation rate between the actual output pulse width and the target pulse width is less than 1%,and the maximum deviation rate between the actual output power and the target power is less than 5%.
