本文建立了处理系统误差的数学模型,提出了用软件处理误差的智能修正方法,并通过实验证明了这种方法的正确性。与传统方法相比较,本方法可减少硬件结构的复杂性和降低系统对元、器件特性指标的要求,并且可获得良好的误差实时修正效果。此外,这一方法对于被测信息作缓慢变化的测试系统都适用。 In this paper, we set up a mathematical model to deal with systematic errors, put forward an intelligent method to correct errors by software, and prove the correctness of the method through experiments. Compared with the traditional method, this method can reduce the complexity of the hardware structure and reduce the system requirements of the element and device characteristics, and can obtain good error correction effect in real time. In addition, this method is suitable for test systems where the information under test is slowly changing.
