Intelligent, efficient and accurate oxygen analyser calibration and compensation method

The invention discloses an intelligent, efficient and accurate oxygen analyser calibration and compensation method. An oxygen analyser main board communicates with upper computer software 1: MC20_recsave_V1 through a UART (Universal Asynchronous Receiver/Transmitter), the communication time interval is adjustable, 1 second is defaulted, the upper computer software 1 is active to send instructions and data to the oxygen analyser main board, the upper computer software 1 controls the whole calibration and measurement temperature compensation process, and the upper computer software 2: MC20_meascal_V1 automatically calculates a slope k, an intercept b and temperature compensation data and writes into a textbox of the lower part of the right side of upper computer software 1: MC20_recsave_V1. The upper computer communicates with the oxygen analyser main board, the upper computer records the data and carries out autonomous calculation, the data are sent to a single chip microcomputer through a formulated protocol,
