Power line carrier equipment and online upgrading method thereof

Abstract

The invention discloses an online upgrading method of power line carrier equipment. The power line carrier equipment comprises a program memory, wherein the program memory comprises an application program memory cell and an upgrading control program memory cell. The method comprises the following steps: entering an interruption state after receiving upgrading starting signal including an equipment address; exiting from the interruption state and entering a circular waiting state after judging that the equipment address of the power line carrier equipment accords with the equipment address in the upgrading starting signal; upgrading according to upgrading information in online upgrading signal after receiving online upgrading information including the upgrading information; judging whether the upgrading is completed; exiting from the circular waiting state and restarting. According to the online upgrading method of the power line carrier equipment and the equipment disclosed by the invention, the software of the power line carrier equipment in the equipment is remotely rewritten under the condition that a seal or an equipment cabinet of power equipment is not damaged, and error repair of the software of the power line carrier equipment on the application site can be carried out without contacting the carrier equipment actually.

Description

technical field [0001] The invention relates to the technical field of power line carrier communication, in particular to a power line carrier device and an online upgrading method thereof. Background technique [0002] Power line carrier communication equipment is usually installed together with power equipment (such as ammeters, etc.) at the application site. These power equipment are usually sealed or locked in the corresponding equipment cabinet for precision or safety considerations and cannot be directly accessed. Power line carrier communication equipment usually runs embedded software, which may have some undetected design errors during design or due to human negligence or other reasons, and these errors may be found during the official operation of the system and need to be corrected; there are also Perhaps due to poor consideration at the beginning of the design, the designed functions cannot meet the new needs proposed later, and the operating software needs to be...

AI Technical Summary

Problems solved by technology

For the reasons mentioned above, for electrical equipment, this kind of connection often means breaking the seal or opening the equipment cabinet, which is unacceptable or at least inconvenient to the user

Therefore, the usual power carrier equipment cannot be upgraded again when it arrives at the application site, or the entire equipment can only be replaced. Otherwise, even if a problem is found, it can only "persist in work despite illness", and it is even more incapable of meeting new needs.
