Embodiment 1

[0073] see figure 1 , figure 1 It is a schematic flowchart of Embodiment 1 of the method for remotely differentiated upgrading the embedded software of the electric energy meter of the present invention.

[0074] In order to achieve the above object, in embodiment 1, the present invention provides a method for remote differentiated upgrade of embedded software of electric energy meter, which includes the following steps:

[0075] Step S10, the client terminal obtains the software version information of the electric energy meter, and compares the software version information with the latest software version information of the client terminal to obtain differentiated data information.

[0076] The client terminal communicates with the electric energy meter through a wireless or wired network, and the client terminal obtains the software version information of the electric energy meter communicated with it through the network.

[0077] The client stores the latest software ve...

Embodiment 2

[0112] see figure 2 , figure 2 It is a schematic flowchart of Embodiment 2 of the method for remotely differentiated upgrading the embedded software of the electric energy meter of the present invention.

[0113] In Embodiment 2, the steps are basically the same as those in Embodiment 1 above, except that the step S11 includes:

[0114] Step S20, the client generates a handover upgrade command.

[0115] After the client obtains the differentiated data information, the client generates a switching upgrade command.

[0116] Step S21, the client encrypts the handover upgrade command.

[0117] The client encrypts the switching upgrade command.

[0118] It should be noted that all existing encryption algorithms can be used to encrypt the switching upgrade command.

[0119]Step S22, the client sends the encrypted switching upgrade command to the electric energy meter.

[0120] After the client encrypts the switch upgrade command, it will encrypt the switch upgrade command

Embodiment 3

[0124] see image 3 , image 3 It is a schematic flowchart of Embodiment 3 of the method for remotely differentiated upgrading the embedded software of the electric energy meter of the present invention.

[0125] In embodiment 3, the steps are basically the same as those in the above embodiment 1, except that the step S12 includes:

[0126] In step S30, the electric energy meter receives a switching upgrade command, and the electric energy meter also includes a system reset area and a backup area.

[0127] The energy meter receives the switching upgrade command sent by the client.

[0128] Step S31 , the electric energy meter stores the update loading interrupt vector data frame in the update loading area into the system reset area.

[0129] After the energy meter is successfully switched, the energy meter will generate an update loading interrupt vector data frame, so that after an interruption occurs during the upgrade process, the upgrade process can be continued accordi...

Abstract

The invention discloses a method for remote differential upgrading of electric energy meter embedding type software. The method comprises the following steps of enabling a client to compare with the latest software version information and the software version information obtained from an electric energy meter, so as to obtain differential data information; enabling the client to send a generated toggling and upgrading command to the electric energy meter; enabling the electric energy meter to send toggling operation result information generated by executing of the toggling and upgrading command to the client; if the toggling is successful, enabling the client to traverse and calculate a first CRC (cyclic redundancy check) sum of an application code of the latest software version information; enabling the client to send the differential data information to the electric energy meter, and after the sending is completed, sending an upgrading completing command to the electric energy meter; enabling the electric energy meter to perform upgrading processing according to the differential data information and the updating completing command. The invention also discloses a system for the remote differential upgrading. The method has the advantage that the program upgrading of the electric energy meter is completed by the client, and the electric energy meter is upgraded according to the differential data information, so the manual cost is reduced, and the technical effect that the upgrading speed is improved is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric energy meters, and in particular relates to a remote differential upgrade method and an upgrade system for embedded software of electric energy meters. Background technique [0002] With the continuous improvement of the automation level of the power grid, the electric energy meter has changed from a mechanical meter to an electronic smart electric energy meter. Features. [0003] At the same time, the State Grid Corporation of China and China Southern Power Grid Corporation have made unified specifications for the technical requirements of electric energy meters, but there are still certain differentiated requirements for power companies of provincial and municipal local bureaus. Therefore, it is necessary to upgrade the energy meter program in batches. [0004] The existing method for upgrading the program of the electric energy meter is mainly to dismantle the upper cover of the electric ene...
