Multi-Parameter Dynamic Sampling Method and Multi-Parameter Dynamic Sampling Device

A multi-parameter dynamic sampling device comprising:

• a configuration unit configured to configure two sampling rates for each sampling parameter of a plurality of sampling parameters;
• a sampling unit configured to select one of the two sampling rates to sample the respective sampling parameter;
• a calculation unit configured to calculate a load of each of the sampling parameters at the selected sampling rate, sort the sampling parameters according to the loads, and determine high-loaded sampling parameters according to a sorting result;
• and
• an adjustment unit configured to determine whether all the sampling parameters have data loss, and if at least one of the sampling parameters has data loss, perform down-sampling on the high-loaded sampling parameters within a range of the configured at least two sampling rates.

An intelligent gateway comprising:

• a processor;
• a memory storing a set of instructions;
• wherein the instructions, when executed by the processor, cause the processor to:
• configure two sampling rates for each of sampling parameter in a plurality of parameters;
• select one of the two sampling rates for a respective sampling parameter to sample the corresponding sampling parameter;
• calculate a load of each of the sampling parameters at the selected sampling rate, sorting the sampling parameters according to the loads, and determining high-loaded sampling parameters according to a sorting result;
• and
• determine whether all the sampling parameters have data loss, and if at least one of the sampling parameters has data loss, performing down-sampling on the high-loaded sampling parameters within a range of the configured at least two sampling rates.
