Air separation unit monitoring method, system and equipment and storage medium

The invention discloses an air separation unit monitoring method, system and equipment and a storage medium, and the method comprises the following steps: S1, monitoring the operation state of an air separation unit in real time, and obtaining the operation data of the air separation unit; s2, judging whether the air separation device is abnormal or not according to the operation data; when the air separation device is abnormal, a low-temperature liquid pump starting instruction is sent out, and a low-temperature liquid pump is controlled to be started; and S3, operating parameters of the air separation unit backup system are monitored in real time, and operating parameters of the low-temperature liquid pump are automatically adjusted according to detection data of the detection equipment. The problem that when the nitrogen gas conveying pipeline in the liquid standby system of the air separation device is put into operation emergently, due to the fact that a control protection system is imperfect, the nitrog
