Centralized direct current sampling value data conversion method and device

The invention discloses a centralized direct current sampling value data conversion method and device. The method comprises the steps of 1, conducting AD conversion; 2, conducting sampling value conversion; 3, performing channel mapping; 4, performing sampling abnormity control; 5, performing rated delay control; and 6, carrying out optical serial port output. The FPGA chip concurrency control is adopted to realize a multi-path AD synchronous sampling mode, so that the whole sampling process does not bring corresponding sampling delay due to the increase of sampling channels, the defect that the FPGA chip cannot perform floating point operation is solved through an equal-proportion amplification mode, data is amplified by 65536 times for processing, the calculation function can be realized only by shifting the data, and data conversion is realized under the condition that the sampling value precision is not influenced. 本发明公开一种集中式直流采样值数据转换方法及装置，方法包括：步骤1、AD转换；步骤2、采样值转换；步骤3、通道映射；步骤4、采样异常控制；步骤5、额定延时控制；步骤6、光串口输出。采
