Problems solved by technology

[0005] 1. The problem of safety and reliability: In the power distribution automation system, the operation and maintenance of the power distribution terminal requires that the communication process must have high reliability, especially for the action execution of specific equipment. Unreliable communication process may lead to parameter setting Accidents such as failure, improper value setting, equipment malfunction, and even large-scale power outages occur
In addition, remote maintenance increases the network security risk of power distribution terminals to a certain extent
[0006] 2. The problem of convenience: the power distribution network itself has the characteristics of complex and cumbersome interweaving, so the number of power distribution terminals in the network is also huge
[0007] 3. The problem of loss of manpower and material resources: There are many devices in the distribution network, and the operation and 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. The maintenance efficiency is low
[0008] 4. Limitations of maintenance software: Many power distribution terminals have different versions of maintenance software, and the changes are diverse, and different models cannot be mixed, that is, the versatility of the maintenance software is not strong

Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] The invention provides an operation and maintenance tool for a power distribution terminal, which includes an operation and maintenance host, an operation and maintenance server and a power distribution terminal. Wherein, the operation and maintenance host is a host device used to perform operation and maintenance operations on the power distribution terminal. An operation and maintenance host can only perform operation and maintenance operations on specific power distribution terminals, which can effectively prevent malicious operation and maintenance and improve the safety and reliability of power distribution terminal operation and maintenance work. The operation and maintenance host has a browser, which identifies the operation and maintenance server through the IP address, sends an HTTP request message containing the opera...

Abstract

The invention discloses a tool and a method for operation and maintenance of a distribution terminal. The operation and maintenance tool comprises an operation and maintenance host, a operation and maintenance server and a distribution terminal. The operation and maintenance server is installed on the distribution terminal; the operation and maintenance server comprises a safety verification unit, a communication unit and an interface unit; the operation and maintenance server is communicated with the distribution terminal through the interface unit and is communicated with the operation and maintenance host through the communication unit; the safety verification unit comprises a decrypted file safety verification module and an authority verification module; the decrypted file verification module is used for performing safety verification on the operation and maintenance host which request operation and maintenance, which effectively prevents malevolence operation and maintenance and dangers caused by misoperation, and guarantees the safety and reliability of the process of operation and maintenance.

Description

technical field [0001] The invention relates to an operation and maintenance tool for power distribution terminals, and also relates to a power distribution terminal operation and maintenance method based on the operation and maintenance tool, which belongs to the technical field of power distribution automation. Background technique [0002] As an effective technical means to improve the reliability of power supply, distribution automation has been paid more and more attention by the power sector. The distribution terminal is a necessary equipment for the construction of distribution automation, and its communication network with the main station system of distribution automation is also a necessary condition for the construction of distribution automation. In order to realize the monitoring of distribution lines and distributed power sources, it is necessary to install a large number of distribution terminals along the distribution lines and distributed power sources, and ...
