摘　　要：根据医用微波理疗机需要对功率进行连续调整的要求,在测试了微波磁控管的平均输出功率和阳极电流关系的基础上,确定了合适的调功方案。系统以一个89C52单片机为中心.由可控硅调压器实现连续的功率调整。系统的管理界面是基于LabVIEW的图形化界面.并通过基于LabSQL的数据库管理系统,实现了治疗档案的在线管理。该控制系统显示直观,调节方便,具有精确定时功能,应用效果良好。According to the request of the medical microwave instrument's power adjusting, the suitable scheme of power adjusting is presented, which is based on the fact that the average output power and anodic ampere characteristic of magnetrons is tested. This system is centered on a MCU of 89C52 and its power continuous adjusting is accomplished with a SCR. The management interface of the system is the graphical interface based on the LabVIEW. And the users' records can be managed on line because of the database which is based on LabSQL. This control system has an intuitionistic display and precise timing function, and can be adjusted convenientl y. The system has a good application effect.
