Embodiment 1

[0049] Refer to attached Figure 1~2 As shown, the present invention provides a technical solution: a minute-level data acquisition method based on HPLC technology, which is applied to a minute-level data acquisition system, and the minute-level data acquisition system includes an acquisition master station 1, a concentrator 2, and a CCO real-time maintenance module 3. At least one STA real-time maintenance module 4 and at least one electric energy meter 5 communicate and interact sequentially, and each electric energy meter 5 corresponds to each STA real-time maintenance module 4 one by one;

[0050] The minute-level data collection method includes the following steps:

[0051] S1, configuring RTC clock information for the STA real-time maintenance module 4, and judging whether to support the minute collection function.

[0052] Specifically, the collection master station 1 performs file synchronization with the concentrator 2, and the STA real-time maintenance module 4 sear...

Embodiment 2

[0069] The embodiment of the present invention also discloses a minute-level data acquisition device based on HPLC technology, which is applied to the above-mentioned minute-level data acquisition system. image 3 shown; including:

[0070] The judging module 100 is configured to configure the RTC clock information for the STA real-time maintenance module 4, and judge whether to support the minute collection function;

[0071] The synchronization module 200 is used for synchronizing the RTC clock information between the CCO real-time maintenance module 3 and the STA real-time maintenance module 4, and starting the minute-level acquisition task;

[0072] The configuration module 300 is used to issue configuration tasks through the acquisition master station 1, and refresh the configuration tasks of the STA real-time maintenance module 4 through the transparent transmission of the concentrator 2 and the CCO real-time maintenance module 3, so that the STA real-time maintenance mo...

Abstract

The invention provides a minute-level data acquisition method and device based on an HPLC (High Performance Liquid Chromatography) technology, which are applied to a minute-level data acquisition system, and the minute-level data acquisition system comprises an acquisition master station, a concentrator, a CCO real-time maintenance module, at least one STA real-time maintenance module and at least one electric energy meter which are sequentially communicated and interacted. Each electric energy meter is in one-to-one correspondence with each STA real-time maintenance module; comprising the following steps: configuring RTC clock information for the STA real-time maintenance module, and judging whether a minute acquisition function is supported or not; the CCO real-time maintenance module and the STA real-time maintenance module synchronize the RTC clock information and start a minute-level acquisition task; through synchronization with node information and an acquisition scheme of the concentrator, configuration tasks of the CCO real-time maintenance module and the STA real-time maintenance module can be kept consistent in a communication channel, so that unnecessary data chaos is avoided, and a minute-level acquisition task is realized by the STA real-time maintenance module.

Description

technical field [0001] The invention belongs to the technical field of electric load data collection, and in particular relates to a minute-level data collection method based on HPLC technology and a device thereof. Background technique [0002] Low-voltage power line high-speed carrier communication (High Power Line Carrier), referred to as HPLC, is a communication method that is stable, reliable, fast in communication speed, safe in data transmission, and can use power lines for data transmission. High-speed carrier communication has been vigorously promoted in the power industry, and its application effect has also been recognized by users. [0003] Smart grid is the latest trend in the development and transformation of electric power in the world today, and is considered to be a major technological innovation and future development trend of the world's power system in the 21st century. Among them, intelligent power consumption and scientific regulation are the main cont...
