A routing-based high-efficiency HPLC station area identification method and system

Abstract

The invention discloses a routing-based high-efficiency HPLC station area identification method, which comprises the following steps: obtaining a table search command, the table search command includes a table search duration, judging whether to perform station area identification according to the table search duration, and obtaining Judgment results; according to the judgment results, perform station area identification and active registration in sequence, or directly perform active registration, obtain the station area registration results and report them as table search results. The invention makes the process of station area identification more flexible and improves the identification efficiency through the change of routing information in the process of station area identification and the process of dynamic console area identification. In the present invention, by interrupting the table search command, the station area identification can be closed at any time during the station area identification process, so that the whole process is simple and controllable, and the identification flexibility is improved.

Description

technical field [0001] The invention relates to the field of HPLC station area identification, in particular to a route-based high-efficiency HPLC station area identification method and system. Background technique [0002] HPLC, ie, high speed broadband power line carrier. [0003] At present, the communication media used in the field of intelligent meter reading, such as PLC, RF, etc., due to the special environment on site or human wiring errors, there is always a problem that the slave node belonging to the station area is registered to the adjacent station area, while the cross-station area The most direct problem is that the success rate of meter reading in the station area decreases. In order to solve the above problem, the prior art mainly adopts the following two methods to identify the station area of ​​HPLC. [0004] These two methods of station area identification were respectively proposed by Beijing Power Grid and State Grid, and the steps are basically the sa...

Problems solved by technology

[0005] The station area identification process proposed by Beijing Power Grid includes: start-up, initialization, identification, locking, and reporting or recruitment. The process is too complicated, increasing the workload of all parties, and the probability of errors in on-site use is extremely high

Moreover, once the process is started, it will be in the normal open state, which will cause STAs to leave the local station area and join the adjacent station area when there is a fluctuation in the station area network, resulting in meter reading in the station area drop in success rate

[0006] Compared with the process of Beijing Power Grid, the station identification process proposed by the State Grid has added the function of closing the station identification. However, this process does not clearly propose when to turn off the station identification. It only proposes that the duration of the station identification is generally 1 day. about

[0007] It can be seen from the above that the technical solutions of the above two station area identification processes are too complicated, requiring multiple interactions between the master station, concentrator, CCO, and STA, and the interconnection and interoperability are poor; and because the station area identification process is located before the meter reading process , before the household change relationship is clarified, all meter services will be closed, so if the station area identification process is too complicated and the duration is too long, it will definitely affect the normal meter reading business, so further improvements to the existing technology are needed
