Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. A non-transitory computer readable medium storing instructions, when executed by at least one processor, causing the at least one processor to implement an early warning method comprising:
obtaining a first detection data set collected by a detection device located at the energy metering point of natural gas, wherein the first detection data set includes sub detection data respectively collected by at least two data detection units of the detection device;
determining a first cluster center set through clustering a first historical detection data set;
determining a first vector corresponding to the first detection data set based on the first detection data set;
determining a first target cluster center based on the first vector and the first cluster center set; and
determining whether the detection device is abnormal based on a distance between the first vector and the first target cluster center;
in response to determining that the detection device is abnormal, for each of the sub detection data in the first detection data set,
obtaining a second vector through removing an element corresponding to the sub detection data from the first vector;
obtaining a second target clustering center through removing an element corresponding to the sub detection data from the first target clustering center; and
determining whether the data detection unit corresponding to the sub detection data is an abnormal data detection unit based on a second distance between the second vector and the second target clustering center.
