However, with the implementation of the IR46 standard, in order to achieve the requirement of "independent metering", the new generation of smart meters adopts the setting of two control units, and its hardware and software structures are different from those of traditional meters. The method cannot adapt to the structure of the new generation of smart meters

Embodiment Construction
[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0038] The power-off data storage method based on the dual-core smart meter provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the management core 102 can communicate with the metering core 104 . The management core 102 can detect the power-down signal sent by the metering core 104 through preset pins, send a start signal to the power storage device, and detect the remaining power supply time of the power storage device. The priority identification of the data, use the data of each component and the basic applic...

The invention relates to a power failure data storage method and device based on a dual-core intelligent electric meter, computer equipment and a storage medium. When it is detected that a power failure signal occurs in the double-core intelligent electric meter, an electric quantity storage device is started, the remaining power supply time of the electric quantity storage device is detected, and according to data priority identifiers corresponding to all components and basic applications in a management core, data corresponding to all the components and the basic applications are used for generating data storage queues; and the data in the data storage queue is stored according to the remaining power supply time and the data storage queue. Compared with a power-down processing mode of a traditional electric meter, the scheme has the effects that the electric quantity storage equipment is arranged in the double-core intelligent electric meter, the data of each component and the basic application are generated into the data storage queue according to the priority, the data is stored, and the data is stored in time when the double-core intelligent electric meter is powered down; power-down data storage adapting to software and hardware structures of a new generation of double-core intelligent electric meters is achieved, and the stability of power-down data storage is improved.
Description
technical field [0001] The present application relates to the technical field of data security, in particular to a method, device, computer equipment and storage medium for saving power-off data based on a dual-core smart meter. Background technique [0002] In my country, electric meters with integrated design have been used in thousands of households. When there is a software or hardware failure, the only feasible measure to ensure the smooth progress of power metering is to replace the entire meter. Moreover, in order to prevent the inaccurate measurement of electric energy caused by the tampering of the meter program by the outside world, the software of the meter in my country is not allowed to be upgraded online, which reduces the service life and adaptability of the meter, and the huge quantity needs to be replaced, resulting in a waste of resources. When the meter is in use due to improper operation or other external forces, there will be a sudden power failure. If t...
