The NB-IoT is constructed in a cellular network, only consumes about 180KHz of bandwidth, can be directly deployed in a Global System for Mobile Communications (GSM) network, a Universal Mobile Telecommunications System (UMTS) network or a Long Term Evolution (LTE) network, supports cellular data connection of low-power-consumption equipment in a wide area network, and has the advantages of low power consumption, low cost, wide and deep coverage and support of mass connection. The NB-IoT-based power utilization check management system provided in this embodiment adopts the NB-IoT network 100 as a communication method, so as to implement fast communication and reduce the cost of equipment and communication usage.
As shown in fig. 1, the NB-IoT-based electricity inspection management system provided in this embodiment includes: the power management system comprises an NB-IoT network 100, a power management module 200 and a plurality of power metering modules 300, wherein the power management module 200 and each power metering module 300 communicate with each other by adopting the NB-IoT network 100, and the power metering modules 300 can be understood as electric meters used by customers. Specifically, the electric energy metering module 300 receives a data acquisition instruction sent by the electric energy management module 200 through the NB-IoT network 100, acquires electrical parameters such as current, voltage, phase, and reverse active power according to the data acquisition instruction, and calculates forward active power according to the acquired current, voltage, and phase data. The power metering module 300 transmits the power data such as the forward active power, the current, the voltage, the phase and the reverse active power to the power management module 200 through the NB-IoT network 100. The electric energy management module 200 acquires the electricity consumption data fed back by the electric energy metering module 300, and judges whether the electric energy metering module to which the electric energy management module belongs is abnormal in electricity consumption according to the electricity consumption data. When detecting information such as current data abnormity, voltage loss, phase error and the like, the electric energy management module 200 determines that the electricity utilization data is abnormal, the electricity utilization of the electric energy metering module to which the electric energy management module belongs is abnormal, and feeds back the abnormal electricity utilization data and/or abnormal electricity utilization behavior information to electricity utilization inspection management personnel in time.
