摘　　要：根据RFID标签制备工艺中导电胶热压固化对温度控制的要求,文中提出了一种基于放大器和铂电阻温度传感器的温度采集电路方案,进行了放大器和温度传感器性能测试以及结论分析。数据表明,该方案中放大器LM324放大性能稳定可靠,可选为温度采集电路的放大器件;传感器测试结果较为理想,有一款铂电阻传感器的响应速率和分辨率均比较理想。该温度采集方案,测温结构简单、易于调试、满足±1℃的控制精度的要求。文中设计的温度采集电路方案除了可满足RFID标签制造工艺需求外,也可用于其他温度控制系统的温度采集方案。A temperature acquisition scheme based on amplifier and temperature sensor was introduced, and the performance tests and experimental analysis about amplifier and temperature sensor were conducted. The temperature acquisition scheme of temperature controller was used in the thermocompression module of RFID tag manufacturing, it can also provide reference for other temperature control system. The test data show that, the amplifier LM324, with stable and reliable performance, can be chosen as the amplifier in the temperature acquisition circuit. And one of the temperature sensors shows ideal response rate and resolution. The temperature acquisition scheme, with its simple structure and easy mounting, meets the requirements of the control precision of ±1℃.
