Problems solved by technology

However, this method needs to divide the terminals into quite a few groups and manually configure the sending time to get roughly balanced sending, and when the number of terminals increases, it is difficult to make dynamic adjustments

Embodiment Construction

[0015] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the present invention involves the master station, the terminal and the communication between the two. The task formulation module of the master station sends the task to the communication module of each terminal through the communication module of the master station, and the terminal communication module receives the task Finally, notify a task scheduling module located in the terminal, the task scheduling module will send the task data to the communication module of the master station through the terminal communication module within the time period specified in the task, and the communication module of the master station will send the task data to the A task data analysis and processing module located at the master station for analysis and processing.

Abstract

The invention discloses a data reporting method of a power utilization information acquisition terminal based on a random value, relating to the field of communication of power systems. The data reporting mode of the current data acquisition system can not make a compromise between the magnitude of communication flow and the distribution uniformity of the communication flow. In the invention, a master station is provided with a task setup module, wherein the task setup module sets up tasks for terminals, sets a data reporting time period for each task and randomly generates data reporting time points for each terminal in the data reporting time period. Since the task setup module randomly generates data reporting time points for each terminal in the data reporting time period of each taskand the reporting time points are uniformly distributed in the reporting time period, the invention avoids the possible unexpected load caused by the active reporting of a terminal, balances the message reporting time and prevents the unexpected load from impacting the communication channel and the master station.

Description

【Technical field】 [0001] The invention relates to the field of power system communication, in particular to a random value-based method for sending data to a power consumption information collection terminal. 【Background technique】 [0002] There are generally two ways to send data to the data acquisition system: [0003] 1. The polling method of the master station. In this way, the master station calls and tests each terminal in a loop. When single-threaded, there will generally not be a bottleneck in the processing capacity of the channel or the host; when multi-threaded, the number of threads can be determined according to the capacity of the channel or the processing capacity of the host, and generally there will be no uncontrollable situation. However, the disadvantage is that a command must be issued before each data upload, which greatly increases the communication traffic. [0004] 2. The terminal actively uploads the method. In this way, the communication traffi...
