The invention provides an analog quantity high-precision acquisition automatic compensation and correction system, which comprises a front-end acquisition module and a processing unit, and is characterized in that the processing unit is in communication connection with the front-end acquisition module; and the processing unit is used for controlling the front-end acquisition module to periodically acquire signals of the zero offset channel, the reference channel and the acquisition channel, calculating a correction coefficient according to the acquired signals of the zero offset channel and the reference channel, correcting an acquisition result of the acquisition channel in real time by adopting the correction coefficient, and outputting the corrected acquisition result. Under an abnormal environment condition, 0.2% of acquisition precision can be ensured; the system has the characteristic of dynamic adaptive compensation, and is strong in anti-interference performance, high in reliability and high in safety.
本发明提供了一种模拟量高精度采集自动补偿修正系统,包括前端采集模块和处理单元,所述处理单元和所述前端采集模块通信连接;所述处理单元用于控制所述前端采集模块定期对零偏通道、基准通道和采集通道的信号进行采集,并通过采集到的零偏通道信号和基准通道信号计算得到修正系数,采用该修正系数对所述采集通道的采集结果进行实时修正后输出。本发明在异常环境条件下,均能够确保0.2%的采集精度;具有动态自适应补偿的特点,抗干扰性强、可靠性高,安全性高。
