Embodiment Construction

[0033] In order to facilitate product maintenance and upgrading, reduce the risks in the process of large-scale promotion of products, and comprehensively support the large-scale communication construction of the power consumption information collection system, the present invention is based on the modular design of the collection terminal without adding any hardware resources. , based on the flooding networking algorithm, a power line carrier remote upgrade method is provided, which can selectively upgrade the collection terminal, so as to solve the problem that the collection terminal cannot be effectively remotely upgraded in the prior art.

[0034] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0035] According to the power line carrier remote upgrade method of the pre...

Abstract

The invention discloses a power line carrier remote upgrading method and a terminal. The method comprises the steps that when a broadcast upgrading command which includes broadcast sending times is received by a concentrator, and if program upgrading times of a collecting terminal fail to reach the broadcast sending times set by the concentrator, it is judged that whether the collecting terminal needs to be upgraded or not; if the collecting terminal needs to be upgraded, then when a first single-package command is received by the concentrator, it is judged that whether the upgrade of a program package in the first single-package command is completely or not; if the upgrade of the program package is unsuccessful, then a second single-package command comprising the program package which are unsuccessful in upgrading is received by the collecting terminal, and peer-to-peer upgrading is carried out on the program package which is unsuccessful in upgrading. According to the power line carrier remote upgrading method and the terminal, upgrading is carried out by using the flooding algorithm transmission, broadcast upgrading is carried out on a to-be-upgraded terminal, and if the broadcast upgrading is unsuccessful, peer-to-peer upgrading can be carried out on the program package which is unsuccessful in upgrading, so that the upgrade successful rate is increased.

Description

technical field [0001] The present invention relates to the field of electric power communication, and in particular, relates to a method for remotely upgrading a power line carrier and a terminal. Background technique [0002] Power line carrier (Power Line Carrier, hereinafter referred to as PLC) is the main communication means in the construction of domestic electricity information collection system. In the electricity information collection system, this means is mainly used to complete the communication between residential users and distribution transformers. Functional applications such as data collection and cost control. At present, during the use of power carrier communication products, there are generally the following problems: [0003] (1) The design of carrier communication products is difficult to achieve perfection, especially the software part, which is prone to errors due to its greater flexibility. Therefore, in the process of use, it is often found that th...
