Abstract

The invention discloses a remote upgrade method of a power utilization information acquisition terminal. The terminal program upgrade file transmission is finished by use of a communication channel of an acquisition system, and the State Grid Enterprise Standard Q/GDW 376.1-2009 < power consumer power utilization information acquisition system communication protocol: master station and acquisition terminal communication protocol> is expanded; on the one hand, the method supports the realization of the file transmission through a standard file transmission command so as to realize the transparent transmission of the file; on the other hand, the method supports the breakpoint resume, the file query, the ftp downloading and like functions. Therefore, the problems of failed upgrade data file issuing caused by the communication fault, the online upgrade occupied system master station resource, and unstable system caused by channel switching are avoided.

Description

technical field [0001] The invention relates to the field of network communication technology and power consumption information collection system, in particular to a remote upgrade method for power consumption information collection terminals. Background technique [0002] As a unified electricity consumption information collection and scheduling platform, the user electricity consumption information collection system (hereinafter referred to as "collection system") is an important part of the smart grid construction. Among them, the acquisition terminal is responsible for data acquisition, data management, two-way data transmission and execution of control commands, and is one of the key equipment of the acquisition system. [0003] As a product, the acquisition terminal needs to go through a process from new technology research and development to maturity. During this process, problems such as terminal functions need to be improved, terminal programs need to be upgraded, a...
