Wherein the distribution component 102 communicates with the command transmitting device 104 via a communication component. The distribution component 102 in the dual-core smart meter may receive the data flushing instruction from the command sending device 104, so that the distribution component 102 may perform data flushing on the management unit and the metering unit in the dual-core smart meter according to the data flushing instruction. The command transmitting device 104 may be a metering master station or an upper computer.

step S202, a first data emptying instruction is sent to a metering unit in the dual-core intelligent ammeter in response to the data emptying instruction sent by the command sending device 104; the first data flushing instruction is used for indicating the metering unit to flush data.
The command sending device 104 may be a device for sending a command, specifically, may be a metering master station or an upper computer, the dual-core smart meter may be a smart meter including a metering core and a management core, and the distribution component 102 in the dual-core smart meter may receive a data emptying instruction sent by the command sending device 104 through a communication component in the dual-core smart meter, where the communication component may utilize a communication module to communicate with the command sending device 104, that is, the dual-core smart meter may utilize the communication module to communicate with the command sending device 104. After receiving the data emptying instruction, the distribution component 102 may send the first data emptying instruction to the metering unit in the dual-core smart electric meter, so that the metering unit empties the data of the metering unit after receiving the first data emptying instruction. The first data flushing instruction may be an instruction formed by the distributing component 102 forwarding the data flushing instruction sent by the command sending device 104 to the metering unit.
Additionally, in some embodiments, the distribution component 102 may further decrypt and authenticate the received instruction before sending the first data flush instruction to the metering unit, including: acquiring an encryption emptying instruction based on the dual-core intelligent ammeter, which is sent by command sending equipment; decrypting the encrypted emptying instruction by utilizing a communication assembly in the double-core intelligent ammeter to obtain a decrypted emptying instruction; and authenticating the decryption emptying instruction, and taking the decryption emptying instruction as a data emptying instruction if the authentication is passed.
Specifically, the instruction sent by the command sending device 104 may be sent in a ciphertext manner, after the dual-core smart meter receives the instruction, the dual-core smart meter may decrypt the instruction in the ciphertext manner, for example, decrypt the encrypted emptying instruction through the communication component, and the distribution component 102 may further perform identity authentication on the decrypted emptying instruction to determine whether the instruction is an instruction sent by the command sending device corresponding to the dual-core smart meter, if the authentication is passed, the distribution component 102 may use the decrypted emptying instruction as the data emptying instruction, so as to empty the dual-core instruction meter by using the data emptying instruction.
Step S204, a first execution result of the metering unit aiming at the first data emptying instruction is obtained, and if the first execution result is successful, a second data emptying instruction is sent to a basic application in a management unit in the dual-core intelligent ammeter; the second data flushing instruction is used for indicating the basic application in the management unit to flush the data.
The metering unit may be a unit for metering in the dual-core smart meter, the metering unit may receive a first data emptying instruction from the distribution unit 102, and empty data in the metering unit according to the first data emptying instruction, so as to obtain a first execution result, the metering unit may return the first execution result to the distribution unit 102, and the distribution unit 102 may determine a next step according to the first execution result, specifically, if the first execution result is successful, the distribution unit 102 may send a second data emptying instruction to a base application in a management unit in the dual-core smart meter, and the base application in the management unit may receive the second data emptying instruction and empty data in the base application in the management unit.

Step S206, a second execution result of the basic application in the management unit aiming at the second data emptying instruction is obtained, and the data emptying state of the dual-core intelligent ammeter is determined according to the second execution result.
The second data emptying instruction may be an instruction for performing data emptying on a base application in a management unit in the dual-core smart electric meter, after receiving the second data emptying instruction sent by the distribution component 102, the base application in the management unit may perform data emptying on each module in the management unit according to a preset sequence, and obtain a corresponding second execution result, where the second execution result may represent a data emptying state of the base application in the management unit, and the base application in the management unit may send the second execution result to the distribution component 102, and the distribution component 102 may determine the data emptying state of the dual-core smart electric meter according to the second execution result. For example, when the second execution result is detected to be successful, the success of data clearing of the dual-core intelligent ammeter can be determined, the traditional ammeter responds to the success of clearing immediately after receiving a clearing command, but the condition that the success of ammeter clearing response is inconsistent with the actual state of the ammeter possibly occurs after actually completing ammeter clearing, the ammeter needs to be cleared repeatedly or read after the ammeter is cleared successfully, the processing result is uncertain, and when the second execution result is detected to be successful in the application, namely, the data clearing success of the dual-core intelligent ammeter is determined after the ammeter is cleared, and repeated confirmation is not needed, so that the processing efficiency can be improved.
According to the data emptying method based on the dual-core intelligent electric meter, the first data emptying instruction is sent to the metering units in the dual-core intelligent electric meter through the data emptying instruction sent by the response command sending device, so that the data of the metering units in the dual-core intelligent electric meter are emptied, when the first data emptying instruction is successfully executed by the metering units, the second data emptying instruction is sent to the basic application in the management unit in the dual-core intelligent electric meter, so that the data of the basic application in the management unit are emptied, and then the data emptying state of the dual-core intelligent electric meter is determined according to the second execution result of the second data emptying instruction returned by the basic application in the management unit. Compared with the traditional method for emptying the intelligent electric meter, the scheme empties the electric meter through the data emptying instruction, and adapts to the structure of the new-generation intelligent electric meter, so that the effect of performing stable and reliable data emptying on the double-core intelligent electric meter can be achieved.
In one embodiment, after transmitting the first data flushing instruction to the metering unit in the dual-core smart meter in response to the data flushing instruction transmitted by the command transmitting device 104, the method further includes: acquiring response time of a first data emptying instruction; the response time is used for representing the time from the sending of the first data emptying instruction to the time before the metering unit responds to the first data emptying instruction; and if the response time is greater than the preset time threshold, determining that the data of the dual-core intelligent ammeter is emptied and fails.

Specifically, the process of the distribution component 102 sending the first data flush instruction to the metering unit may be: the distribution component 102 firstly forwards the data emptying instruction to an interaction component in the dual-core intelligent ammeter, and then the interaction component sends the data emptying instruction to the metering unit, so that the sending of the first data emptying instruction is completed. In addition, when the distribution component 102 determines that the data of the dual-core smart meter fails to be emptied, the execution of the data emptying instruction may be stopped, and the emptying failure information may be sent to the command sending device 104, so that the command sending device 104 may perform corresponding processing, such as resending or generating detection information of the dual-core smart meter, or the like, according to the emptying failure information.
Through the embodiment, the distribution component 102 can determine that the data of the dual-core smart meter fails to be emptied when the response time of the first data emptying instruction exceeds a certain time, so that the deadlock can be avoided when the data emptying instruction is executed, and the efficiency of data emptying is improved.
In one embodiment, after obtaining the execution result of the metering unit for the first data flushing instruction, the method further includes: if the first execution result is failure, determining that the data of the dual-core intelligent ammeter is failed to empty; after obtaining the second execution result of the base application in the management unit for the second data emptying instruction, the method further comprises: and if the second execution result is failure, determining that the data of the dual-core intelligent ammeter is failed to be emptied.
In this embodiment, the first data emptying instruction may be an emptying instruction for a metering unit in the dual-core smart meter, the second data emptying instruction may be an emptying instruction for a basic application in a management unit in the dual-core smart meter, after receiving the first data emptying instruction sent by the distribution component 102, the metering unit may empty data of the metering unit based on the first data emptying instruction, and obtain a first execution result, return the first execution result to the distribution component 102, and the distribution component 102 may determine a next step according to the first execution result, specifically, when the distribution component 102 detects that the first execution result is unsuccessful, may determine an emptying failure of the dual-core smart meter, and send information of the emptying failure to the command sending device 104, so that the command sending device 104 performs corresponding processing according to the information of the emptying failure, for example, resends the data emptying instruction or detects the dual-core smart meter.

And the distribution component 102 may determine that the data emptying instruction sent by the command sending device 104 is successfully executed when the second execution result is detected to be successful.
Through the embodiment, the distribution component 102 can stop continuing to execute and return failure information to the command sending device 104 when the basic application in the metering unit or the management unit fails to execute the command, and compared with a method that the conventional dual-core smart meter receives the command and returns successful execution to the upper computer, the embodiment can return corresponding information according to actual execution conditions, thereby realizing improvement of the execution authenticity of the data emptying command, and simultaneously stopping continuing to execute the data emptying command in time when the execution fails, avoiding execution entry deadlock and improving the execution efficiency of the data emptying command.
