| Abstract: | 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. |
