The invention provides an environmental protection monitoring method and system based on power consumption perception, and the method comprises the steps: carrying out the transient detection througha collection device according to a set time, and determining a current waveform effective value of each period; according to the current waveform effective value of the current period and the currentwaveform effective value of the previous period, determining voltage waveforms corresponding to steady-state current waveforms of continuous T periods before switching of the electrical load; based onthe voltage waveforms corresponding to the steady-state current waveforms of continuous T periods before switching of the electrical load, determining the current and power during switching of the electrical load; obtaining a current waveform and power when the environmental protection equipment operates independently from a priori library; and judging whether to carry out environmental protection treatment or not according to the current and the power when the electrical load is switched and the current waveform and the power when the environmental protection equipment operates independently. The method is simple and feasible.
Description
technical field [0001] The invention relates to the technical field of environmental protection monitoring, in particular to an environmental protection monitoring method and system based on electricity consumption sensing. Background technique [0002] Environmental protection is a basic national policy of our country. At present, the overall deterioration of my country's environmental status has not been fundamentally curbed, environmental contradictions are prominent, and the pressure continues to increase. Environmental problems have become one of the important factors threatening human health, public safety and social stability. The discharge of pollutants is still quite large, which is far higher than the self-purification ability of the environment; the task of industrial pollution control is still quite heavy, and some places that have been treated have relapsed. Industrial production is an important source of environmental pollution. There are many kinds of pollut...
