Problems solved by technology

[0003] The original maintenance method is to connect 50 collectors to the concentrator, and each collector is connected to 32 tables. The parameters of these tables can only be manually prepared, which is not only a heavy workload but also extremely error-prone

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The method of the present invention is a method of using the wildcard of the electric meter protocol DLT645-1997 / 2007 to read the electric quantity, and using the garbled or wrong data and normal data without conflicts generated during the conflict of the RS485 bus to analyze and obtain the addresses of all electric meters under the collector . Such as Figure 1 to Figure 3 The method for automatically searching the address of the electric meter under the collector as shown, the steps are:

[0023] (1) The concentrator 1 sends a wildcard address to the collector 2 to stimulate the collector to collect the data of all electric meters 3; in this embodiment, the first wildcard is AAAAAAAAAAA.

[0024] (2) Collector 2 sends back the data collected in 1~3S to concentrator 1, and concentrator 1 analyzes the data collected; in this ...

Abstract

The invention discloses a method for automatically searching an electric meter address below a collector, comprising the following steps: 1, a concentrator sends a wildcard address to the collector and excites the collector to collect the data of all electric meters; 2, the collector sends the data collected in 1-3S back to the concentrator, and the concentrator analyzes the collected data, wherein the analysis process is that: (1) if no data is input, no electric meter is accessed; (2) if a complete data is received and no other data is followed, a single electric meter is accessed; (3) if the searched data is messy codes, error messages or correct message and other data is followed, a plurality of electric meters are accessed; 3, and when search shows that a plurality of electric metersare accessed, the wildcard address is replaced to repeat the step 1 and the step 2 till the address of the single electric meter is searched. The method can reduce maintenance work of an electric power information collecting system, reduces maintenance cost, and increases running effect of the collecting system.

Description

technical field [0001] The invention relates to a method for searching the address of the electric meter, in particular to a method for searching the address of the electric meter under the collector to obtain the address of the electric meter. Background technique [0002] In 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, the workload of system maintenance is increasing, and the maintenance cost is also increasing. . Maintenance problems have increasingly restricted the operation effect of the entire power information collector. [0003] The original maintenance method is to connect 50 collectors to the concentrator, and each collector is connected to 32 tables. The parameters of these tables can only be manually prepared, which is not only a heavy workload but also ext...
