摘　　要：设计了一种用于妇科术后凝血的热极探头的温度控制系统,系统基于MSP430F149单片机,采用铂电阻测温元件和桥式电路采集信号,同时使用分段设置PID参数的控制方法控制加热元件,实现了对热极探头的温度控制。测试实验结果表明,分段设置PID参数的控制方法不仅可靠有效,使控制精度满足要求,而且减少了调节时间、克服了由于环境温度造成的影响。The temperature of heat probe must be well controlled for an efficient cruor of surgery wound and the safety of patients.This paper proposes a system including a thin film resistance temperature detector（RTD）and a bridge circuit for controlling the temperature of heat probe during the cruor after gynecologic surgery.The temperature control was achieved by a PID of which parameters were set sectionally.It is demonstrated that the proposed system can precisely and efficiently control the temperature,and circumvent the environmental effect.
