摘要:
温度传感器被广泛用于工农业生产、科学研究和生活等领域，在温控系统中发挥着重要的作用。而高精度的温控系统在测控仪器开发以及工业深加工过程中占有相当重要的地位，因此设计开发高精度的温控系统具有很强的应用价值和现实意义。本文在温控系统硬件设计的基础上，通过增量式PID算法，设计完成了一套控温范围在±0.1℃的高精度温控系统，相比现有同类温控系统，精度提高近10倍。Temperature sensors are widely used in industrial and agricultural production, scientific research and other areas of life, and play an important role in the temperature control system. The high precision temperature control sys-tem has a very important place in measurement and control instrument development and deep processing industry. So, it has very strong application value and practical significance to design and develop a high precision temperature control system. In this paper, based on the hardware design of temperature control system, through incremental PID algorithm, a design of a temperature control in the range of ±0.1°C high precision temperature control system is completed, when compared with the existing similar temperature control systems, precision increases nearly 10 times.
