Problems solved by technology

[0003] 1. The problem of reliability: In the power distribution automation system, the maintenance of terminal equipment requires that the communication process must have high reliability, especially for the specific actions performed by equipment. Unreliable communication process may lead to parameter setting failure, Accidents such as improper setting of fixed value, misoperation of equipment, or even large-scale power outages occur
[0004] 2. Convenience and quickness: the power distribution network itself has the characteristics of complex and cumbersome interweaving, so the number of terminal devices in the network is also huge
[0005] 3. The problem of saving manpower and material resources: There are many devices in the distribution network, and the maintenance of each device often requires the cooperation of many staff, which consumes a lot of manpower and material resources, and also wastes a lot of time, and the maintenance efficiency is low.
[0006] 4. Limitations of maintenance software: Many distribution network automation terminal equipment have different versions of maintenance software, and different models cannot be mixed, that is, the maintenance software is not universal
[0007] At present, the existing maintenance methods for distribution network automation terminal equipment in the distribution network still have great defects and deficiencies in the field application process

Abstract

The invention provides a method and a system for remotely maintaining a terminal device of a power distribution network and a corresponding terminal device, which are based on an HTTP (hyper text transport protocol) transmission protocol, utilize an embedded hardware platform and browser software, and depens on the original data acquisition network of the power distribution network to perform remote maintaining tasks such as reading status, uploading and downloading parameters, setting fixed values and upgrading on line to the automatic terminal device of the power distribution network.

Description

technical field [0001] The invention belongs to the field of distribution network automation systems, and in particular relates to a method, a system and a corresponding terminal device for remotely maintaining terminal devices of a distribution network. Background technique [0002] On the distribution network, the maintenance of terminal equipment is a necessary means to ensure the normal operation of distribution network automation terminal equipment. Compared with other fields, the research on remote maintenance of terminal equipment in distribution network started relatively late, and has not yet entered the general practical stage. Due to the characteristics of the distribution network, at present, the automatic remote maintenance of terminal equipment in the distribution network mainly faces the following problems: [0003] 1. The problem of reliability: In the power distribution automation system, the maintenance of terminal equipment requires that the communication...
