[0087] Further, refer to image 3 , which is a partial flowchart of the second embodiment of the data configuration method of the electric energy meter of the present invention, based on the first embodiment, the step S200 includes:

[0088] Step S210, receiving the preset theoretical check value sent by the host computer;

[0089] Step S220, according to the flag bit information of each of the data packets in the buffer area, calculate an actual check value through a preset check method;

[0090] Those skilled in the art can understand that there is corresponding flag bit information in each data packet.

[0091] Step S230, comparing the theoretical verification value with the actual verification value;

[0092] If it is determined that there is an abnormality in the reception, the step of subpackaging the data in the buffer area for cleaning includes:

[0093]Step S310, if the theoretical check value is inconsistent with the actual check value, then divide the data in the...

Abstract

The invention discloses a data configuration method of an electric energy meter, the electric energy meter and a readable storage medium. The data configuration method of the electric energy meter comprises the following steps: receiving data sub-packets sent by an upper computer according to a time sequence, and storing the data sub-packets in a cache region in sequence; checking whether each data sub-packet in a cache region has a receiving abnormity or not; if it is determined that the receiving exception exists, all the data sub-packets in the cache region are cleaned, and data configuration failure information is sent to the upper computer, so that the upper computer resends the data sub-packets; and if it is determined that the receiving exception does not exist, transferring the data sub-packets in the cache region to a destination address storage region for storage. According to the invention, the condition of abnormal function operation caused by parameter configuration errors of the electric energy meter can be avoided.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a data configuration method of the electric energy meter, the electric energy meter and a readable storage medium. Background technique [0002] At present, when the upper computer is setting the parameters of the electric energy meter and needs to transmit relatively large data packets, due to the limitation of the RAM (random access memory) built in the electric energy meter, it can only receive relatively small data at a time. package (and if the RAM memory built in the electric energy meter is to be increased, the cost of the electric energy meter will be greatly increased), therefore, for relatively large data packets, the host computer often transmits them by subpackaging, that is, through Divide a relatively large data package into multiple smaller data sub-packets, and send them to the energy meter in turn to achieve normal data transmission. [0003] However, in th...
