Step 4, data storage: the gathered data receiving is stored；
Step 5, parameter is compared with set point: will set in data and zigbee-3g embedded gateway system (2) of storage
Fixed parameter area is compared；
Step 6, parameter regulates and controls: enters line parameter regulation and control according to result of the comparison.
