Smart electricity meter case based on dual authorization of remote cloud and short-range bluetooth

Abstract

The invention discloses a smart electricity meter case based on dual authorization of remote cloud and short-range bluetooth. The smart electricity meter case includes: a case body; a PLC wideload apparatus, an ESAM module in conformity with the domestic commercial password encryption algorithm and a wideload electricity meter device which are arranged inside the case body, and a short-range bluetooth apparatus, a carrier wave power supply, a metering chip, a detection apparatus and a memory which are connected to the PLC wideload apparatus; related data acquired by the metering chip and the detection apparatus being transmitted to a main device through a power line; the carrier wave power supply transmitting a power supply on / off signal to a cloud terminal or a hand-held terminal via an electricity wideload apparatus; the memory and the ESAM module both provided with authorization codes, temporary authorization codes and an invalid self-destruction module; a RS485 interface, an Internet of Things identification and a switch which are arranged outside the case body; a hall sensor which is connected to the switch. According to the invention, the smart electricity meter case enables automatic learning and identification of the electricity meter which is installed inside the case body, which increases safety of the smart electricity meter, and the bluetooth short-range authorization is applied to on-site maintenance staff, which is much easier to use.

Description

technical field [0001] The invention relates to the technical field of smart meter boxes, and more specifically relates to a smart meter box based on remote cloud and short-distance bluetooth dual authorization. Background technique [0002] The smart meter box is the smart terminal of the smart grid. It is no longer a traditional meter box.
