Embodiment Construction
[0047] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0048] Such as figure 1 as shown, figure 1 It is a schematic diagram of the electric energy meter structure of the hardware operating environment involved in the solution of the embodiment of the present invention. The electric energy meter may include: a processor 1001 , such as a CPU, a network interface 1003 , a memory 1004 , and a communication bus 1002 . Wherein, the communication bus 1002 is used to realize connection and communication between these components. Optionally, the network interface 1003 may include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1004 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1004 may also be a storage device independent of the aforementioned processor 1001 . ...

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: copying data information of a destination address storage area, and storing the data information as backup data information in a cache area; receiving data sub-packets sent by the upper computer according to a time sequence, and storing the data sub-packets in a destination address storage area in sequence; checking whether each data sub-package of the destination address storage area has a receiving abnormity or not; and if it is determined that the receiving is abnormal, covering the data information of the destination address storage area with the backup data information, and sending data configuration failure information to an upper computer, so that the upper computer retransmits the data sub-packets. 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...
