The metering core 104 may be a chip for realizing the metering function of the electric meter in a dual-core smart electric meter, the electric quantity storage device may be a super capacitor, the super capacitor is a power supply which is between a traditional capacitor and a battery and has special performance, electric energy is stored mainly by electric double layers and redox pseudocapacitance charges, but no chemical reaction occurs in the process of energy storage, the energy storage process is reversible, the capacity of the super capacitor is very large and is the same as that of the battery, so the super capacitor may also be called a "capacitor battery", after the management core 102 is powered on, the super capacitor can be charged, and can provide a power supply for the management core 102 when the management core 102 is powered off, and the super capacitor can be arranged in the management core of the management core 102. The management core 102 may be provided with a plurality of software modules, such as a platform management service and a super capacitor monitoring module, where the platform management service may be used to manage the dual-core smart electric meter, and the super capacitor monitoring module may be used to monitor and manage the electric quantity storage device; the management core 102 may receive a power-down signal sent by the metering core 104 through the platform management service, and the platform management service may send a start signal to the electric quantity storage device by using the super capacitor monitoring module after receiving the power-down signal, so as to start the electric quantity storage device, such as a super capacitor; the management core 102 may also receive a power-down signal directly through the power detection pin and send a start signal directly to the power storage device.

The management core 102 may obtain, for example, a data priority identifier corresponding to each component and the basic application when the management core 102 is powered down, and generate a data storage queue using data of each component and the basic application according to the priority identifier of the data in the multiple components and the basic application, specifically, the management core 102 may determine the priority of each data according to the data priority identifier of the data in each component and the basic application, and may store the data of each component and the basic application into the data storage queue in a manner that the priority is from high to low, for example, store the data with the highest priority into the first bit of the data storage queue, and continue to store the remaining data according to a descending order of the priority, thereby obtaining the data storage queue.

The management core 102 may determine the priority of the data in each component and the basic application according to the preset priority rule table, for example, the management core 102 may query the data in the preset priority rule table, so as to obtain the priority corresponding to the data in the preset priority rule table. After determining the priority of the data, the management core 102 generates a data priority identifier corresponding to each data according to the priority of each data, and adds the data priority identifier to the data of each component and the basic application, thereby obtaining the data with the data priority identifier.
Through the embodiment, the management core 102 can determine the data priority of each component and the basic application in the management core 102 through presetting the priority rule table, and can also add the data priority identification for the data, so that the management core 102 can store the data according to the data priority identification and the identification when the power failure occurs, the power failure data storage of a software and hardware structure suitable for a new generation of double-core smart electric meters is realized, and the effect of the stability of the power failure data storage is improved.

Specifically, the management core 102 may store the data in the data storage queue by using a specific algorithm, and specifically, the management core 102 may store the data in the data storage queue by using a non-preemptive priority algorithm. The non-preemptive priority algorithm may be an algorithm for obtaining priority processing after data enters the system in order to take care of urgent jobs. Specifically, the management core 102 may store data with a high priority in the data storage queue, and once a certain data enters a storage processing phase, the management core 102 may execute the storage phase until the storage of the data is completed. For example, with a non-preemptive priority algorithm, data P1 comes first, so data P1 is processed first until it ends, time 10; during the 10 time, data P2 comes first, then P3, P4 and finally P5, and since the data cannot preempt the data of P1, only P1 can be waited for to complete. The priority of P4 is highest in these wait data, so when P1 completes execution, data P4 is executed first. By analogy, the final available storage order is: p1 ═ P4 ═ P3 ═ P5 ═ P2.
Through the embodiment, the management core 102 can store the data in the data storage queue based on the non-preemptive priority algorithm, so that the integrity of data storage is ensured, namely, the data storage is not lost due to the queue insertion of the storage process of other data, the power failure data storage suitable for the software and hardware structure of the new generation of double-core smart electric meter can be realized, and the effect of the stability of the power failure data storage is improved.
In one embodiment, further comprising: if the detected residual power supply time is lower than the processing time corresponding to the data in the current data storage queue, stopping processing the data; the power down process information including the data that has completed processing is sent to the platform management application in the management core 102.

The management core 102 may always detect the remaining power supply time of the power storage device in the data storage process after the power failure, if the management core 102 detects that the remaining power supply time is lower than the processing time corresponding to the data in the current data storage queue, for example, the remaining power supply time cannot complete the storage process of the data currently being processed, the management core 102 may stop the processing of the queue and stop the processing of the data, and the management core 102 may further send power failure processing information including the processed data to the platform management application after stopping the processing of the data, for example, which data has been stored, which data has not been stored, and the storage progress of the data that has not been stored, and the platform management application may store and process the information. Where the platform management application may be disposed in the management core 102.
The management core 102 may generate and transmit the power down processing information when the data store queue processing is stopped, that is, may generate the power down processing information when all the data store queues are completely stored, or may generate the power down processing information when the processing of the data store queues is interrupted.
