Abstract

The invention discloses an electric energy meter file verification method and system, and the method comprises the following steps that an upper computer obtains a file data package, calculates the verification information of the file data package, builds a communication link with an electric energy meter, obtains the size of the file data packet, and sets a storage space and a bitmap space; the upper computer sends the file data packet to the electric energy meter and acquires bitmap information when the file data packet is stored; the upper computer obtains the bitmap information and judges whether a packet is lacked or not according to the bitmap information; the data packet is retransmitted according to the bitmap information, and file verification is performed for executing file upgrading operation. According to the method and the system, the size of the upgrading file is calculated in the upgrading process, the needed bitmap space is calculated according to the size of the upgrading file, the bitmap space is used for rapidly judging whether a data packet is lost or missed to be sent or not, the upper computer executes rapid retransmission according to bitmap information, and the interaction efficiency of the electric energy meter and the upper computer is improved.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a method and system for verifying electric energy meter files Background technique [0002] At present, the reliability judgment of the energy meter for the upgrade file is mainly through the comparison of the verification data uploaded by the host computer with the verification result calculated by the host computer itself for the upgrade file. If they are the same, the verification is successful and further issued File upgrade instruction; if different, stop the upgrade operation. The host computer does not have a resending mechanism for the above-mentioned energy meter file upgrade method, and it is impossible to quickly and accurately determine whether there is packet loss or leakage during the file upgrade process. It is necessary to wait until all the upgrade files have been verified before judging whether there is packet loss or Missing, resulting in a delay in judgm...
