Problems solved by technology

For example, if the first-come-first-served scheduling rule is used, the status update data packet may experience the smallest average network delay, but it cannot guarantee the optimal information freshness. If the last-come-first-served scheduling policy is used, it may reduce Information age improves the freshness of information, but it will increase the average network delay. The existing technology cannot reduce the average network delay while improving the freshness of information, and the system stability is poor

Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only It is a part of the embodiments of this application, not all of them.

[0024] The method for remotely updating the user's power consumption state in this embodiment includes:

[0025] S01: The remote monitoring center sends a status update command to the low-voltage centralized reading terminal;

[0026] S02: After receiving the instruction, the low-voltage centralized reading terminal enters the working state from the dormant state, and starts to collect the user's electricity load state information;

[0027] S03: The low-voltage centralized reading terminal sends the user's electricity load state information t...

Abstract

The invention provides a remote updating method for the power utilization state of a user. According to the remote updating method for the power utilization state of the user, the network delay from a low-voltage centralized meter reading terminal to a remote monitoring center is estimated in real time, and the moment when the next state updating instruction is sent to the low-voltage centralized meter reading terminal is determined on line based on the information freshness; and at each decision moment of the moment when the next state updating instruction is sent to the low-voltage centralized meter reading terminal, the information freshness threshold parameter is regulated and controlled, so that the information freshness and the network delay are enabled to be optimal. According to the invention, the information freshness requirement of remote state updating is met, and the data packet experiences relatively small network delay, so that the state remote updating system is stable.

Description

technical field [0001] The invention belongs to the field of power grid monitoring, and in particular relates to a method and a system for remotely updating a user's power consumption state. Background technique [0002] With the development of Internet of Things applications such as smart factories and autonomous driving, remote monitoring, remote control, etc. update the state perception of remote environments more and more frequently, and the real-time requirements for state updates are becoming more and more stringent. The real-time information is a performance indicator describing the freshness of remote status update, remote control and other information for many years. The real-time information involves the concept of information age, and the information age is defined as: For a system in which a data source transmits the status update information generated by it to the remote monitoring terminal through the communication network, the information age is defined as the...
