Claim 19:
20. The non-transitory computer-readable storage medium according to claim 19, wherein:
both the sample data of the suction end and the sample data of the discharge end comprise data corresponding to a number M of statistical indicators;
before training the fault diagnosis model, the operations further comprise:
based on the sample data of the suction end, selecting at least one statistical indicator with a difference significance parameter greater than a first threshold value from the number M of statistical indicators as the number P of suction end statistical indicators, wherein the difference significance parameter represents an indicator difference degree of the fluid device in a normal state and in a fault state; and
based on the sample data of the discharge end, selecting at least one statistical indicator with a difference significance parameter greater than a second threshold value from the number M of statistical indicators as the number Q of discharge end statistical indicators;
wherein training the fault diagnosis model based on the sample data of the suction end, the sample data of the discharge end, and the input-output difference sample data comprises:
training the fault diagnosis model at least based on data corresponding to the number P of suction end statistical indicators in the sample data of the suction end, data corresponding to the number Q of discharge end statistical indicators in the sample data of the discharge end, and the input-output difference sample data,
wherein M is a positive integer greater than or equal to P and greater than or equal to Q.
