在工业生产中,特别在科学研究的实践中,有很多场合要求解决精密测温问题。要提高测温精度,除合理地选择测温元件外,测量系统的零漂、温漂、非线性是提高测量精度的一大障碍。在通常的模拟电路或随机逻辑电路中,要解决上述问题是困难的。本文以一个实际例子说明如何应用微处理机技术来解决这些问题。 In industrial production, especially in the practice of scientific research, there are many occasions for solving the problem of precision temperature measurement. To improve the temperature measurement accuracy, in addition to a reasonable choice of temperature measurement device, the measurement system zero drift, temperature drift, nonlinearity is to improve the measurement accuracy of a major obstacle. In conventional analog circuits or random logic circuits, it is difficult to solve the above problems. This article uses a practical example to illustrate how to apply microprocessor technology to solve these problems.
