设计采用单片机作为系统的智能核心，被测热电偶与标准热电偶捆绑后放入检定炉中，其输出引线通过补偿导线引入冰瓶中，进行冷端温度补偿；被测热电偶与标准热电偶各个检温点的热电势信号由低电势数据采集电路取得，并在采集电路中对其进行放大、A/D转换处理后，变成单片机能识别的数字量送入单片机处理；单片机通过执行程序，计算出被测偶与标偶的热电势的最大偏差，然后与允许的最大偏差相比较，判断出被测热电偶是否合格，完成对热电偶的自动检定 。-Design by single chip microcomputer as the core of the system of intelligent, measured thermocouple and standard thermocouple after verification furnace in bound, the output leads through the compensation conductor BingPing introduced in the cold end temperature compensation　Be measured with each inspection standard thermocouple thermocouple temperature point of thermoelectric potential by low signal potential data acquisition circuit made, and in its acquisition circuit to amplify, A/D conversion processing, into single chip can identify the digital quantity into SCM processing　SCM through the execution procedures, calculates the measured accidentally and standard of the biggest accidentally thermoelectric potential deviation, and then and maximum allowable deviation, in comparison to figure out whether tested thermocouple qualified and the completion of the automatic verification of thermocouples.
