It is reported that on November 28, 2017, Shenzhen Kelu Electronic Technology Co., Ltd. applied for a national invention authorized patent-centralized meter reading system collector and meter asset number collection management method. The invention relates to a centralized meter reading system, in particular to a collector and an electricity meter asset number collection management method.
Background of the inventionIn the process of building a smart grid, in order to improve the two-way interaction between the grid and users and the value-added service level of electricity consumption, the scale of the power information collection system is getting larger and larger, and the centralized meter reading system is being used more and more widely. System maintenance work The quantity is increasing, and the maintenance cost is increasing. Maintenance problems have increasingly restricted the operation effect of the entire centralized meter reading. The current concentrator completely relies on the master station to issue measurement point parameters to it, directly collects the meter data, the collector relays and forwards the concentrator command, and forwards the response of its power meter. The address of the connected meter can be obtained through the response of the meter. . At the concentrator
If you configure the information of the collector, you can easily understand the composition of the system, but the amount of engineering is huge, the cost is high, the management is chaotic, and it is easy to make mistakes. At present, it is also developing in the direction of not equipped with the information of the collector. If the collector information is not configured, the collector is an invisible cassette to the concentrator. Once a collector fails, it will be impossible to find out, which brings great difficulties to maintenance.
The disadvantage is: once the local area is adjusted, the collector or the meter is replaced, the collector fails, etc., you must go to the site to confirm the relevant information, and then return to the master station to re-issue the parameters, which leads to low intelligence and maintenance personnel. Running around looking for installation points for collectors and concentrators, the work efficiency is quite low.
Summary of the inventionThe technical problem to be solved by the present invention is to provide a centralized meter reading system collector and an electricity meter asset number collection management method, which brings benefits to the efficient operation of the system, maintenance management, and system monitoring.

The picture shows the overall framework of the centralized meter reading system
As shown in the figure, a centralized meter reading system collector and an electricity meter asset number collection management method. The centralized meter reading system includes a master station, a concentrator, a carrier meter, a collector and an electricity meter; the master station is connected to the concentrator Communication, the concentrator is connected to the carrier meter and the collector for communication, and the collector is connected to the electricity meter for communication; the collector and the meter asset number collection management method includes the following steps: (1) The concentrator collects regularly every day (2) After receiving the broadcast, the collector starts to search for the asset number of the meter; (3) The concentrator waits for M minutes, M>5, and then sends the report to the collector. And the asset number of the collector; (4) The collector reports its own asset number and the asset number of the meter attached to the collector to the concentrator; (5) The concentrator updates the meter and its corresponding collection according to the report of the collector (6) The concentrator reports the asset numbers of the collectors and electricity meters to the master station; (7) The master station draws the asset number management topology of the centralized meter reading system in the station area according to the relationship between the concentrator, collector and electricity meters Figure.
As an improvement, the collector is provided with a table for recording the meter asset number, the meter information mark found this time, the newly-added meter information mark and the effective meter information recording mark, and the data and records of the meter are initialized. The flag is zero.
The invention realizes the function of collecting and managing the asset number of the collector electricity meter of the centralized meter reading system, provides a very convenient maintenance method for the collector or carrier meter in case of failure and replacement, and reduces the workload of the maintenance staff of the metering system of the centralized meter reading system. At the same time, in the process of collecting the asset number of the collector's electricity meter, the collector and the carrier meter can work normally, and the impact on meter reading is very small.
