工业无线微机遥测系统误差原因及精度分析

为了使工业无线微机遥测系统获得的数据准确、可靠、系统误差必须在允许的范围内。工业无线微机遥测系统误差主要来自系统取样，编码和信道传送信号过程，详细分析了这三个环节产生误差的具体原因。

Error Causes and Precision Analysis for Industrial Computer-Based Telemetery System,

In order to obtain accurate and reliable data, system errors shall be controlled to an allowable limit. The errors in an industrial computer-based telemetery system are created mainly in the causes of systematic sampling, coding and signal transmission. Specific error causes are analysed respectively. Based on the theory, of error, measurement errors are classified into three categories: systematic error, random error and extensive error, and the data precision is determined in the following procedure: (1)classify the category of the errors; (2)decide whether systematic or extensive errors exist in the data measured; and (3)reject the abnormal data (extensive error), if any. Because computers are powerful in data processing, computer-based telemetery system can be greatly improved in terms of its precision provided sensors are duly selected and signals correctly acquired.
