摘要
为了提高工业控制中温度采集的准确性和可靠性,针对单片机控制温度系统的现状,从硬件电路及软件两方面采用不同的抗干扰措施。硬件电路从电源、温度控制电路等,采用不同抗干扰技术;软件方面重要采用了数字滤波中的限幅滤波法,使采集到的温度准确又可靠,具有实用价值,可以推广。
In order to improve the reliability and accuracy of temperature measurement in industrial control,In view of the current situation of singlechip temperature control system,Anti interference measures different from the two aspects of hardware and software. The hardware cirouit from the power supply,temperature control circuit, using different anti jamming technology;The use of digital filter in software important of limiting filtering method. It to the collected temperature precise and reliable ,It has practical value, can be extended.
