Embodiment 1
[0021] like figure 1 , An embodiment provides a method for improving the success rate of the communication carrier wave by dynamically adjusting the data frame length according to the present invention, a method comprising: power line carrier concentration meter reading system in the data collection process, the concentrator will be sent via a short carrier network meter reading command to the meter, the meter meter received command, to the concentrator, the concentrator comprises a network sending data frames longer carrier: power Line carrier concentrator, carrier meter, low-voltage power network, the meter module receives carrier extension meter reading sub frame mode subcontracting by protocol, if the meter reading process, response data is greater than the length L1 of the meter, the meter meter data carrier module to the cache, then the press is not larger than L1 into N sub-package, is no greater than a sub obtain packet random delay after a random delay window W1 is sequen...

The invention provides a method for improving a carrier communication success rate by dynamically adjusting a data frame length, and relates to the field of data acquisition of a power carrier centralized meter reading system. The method for improving the carrier communication success rate by dynamically adjusting the data frame length comprises the following steps that in the data acquisition process of a power carrier centralized meter reading system, a concentrator sends a short meter reading instruction to an electric meter through a carrier network, the electric meter receives the meter reading instruction and sends a long data frame to the concentrator through the carrier network, and the concentrator sends the data frame to the concentrator through the carrier network; the concentrator comprises a low-voltage power line carrier concentrator, a carrier electricity meter and a low-voltage power network, the electricity meter carrier module receives the extended sub-package meter reading frame and performs a sub-package mode according to a protocol, and if the response data length of the electricity meter is greater than L1 in the meter reading process, the electricity meter carrier module firstly caches electricity meter data. According to the method for dynamically adjusting the data frame length and improving the carrier communication success rate, the electricity meter is read quickly, and communication data is accurate.
Description
Technical field [0001] The present invention relates to a power line carrier meter reading system of data acquisition, and in particular as a carrier to improve the success rate of the communication by dynamically adjusting the data frame length method. Background technique [0002] Acronym power meter, the power meter is used to measure, also known meter, fire table, power meter, kilowatt hour meter, refers to various electrical measurement by the meter. The first meter (also called meter) 1881 is made in accordance with the principle of electrolysis, although weighing dozens of kilograms per meter, very heavy, nor guarantee the accuracy, however, was still as a scientific community a major invention people's attention and praise, and quickly adopted it in the project, with the development of science and technology in 1888, AC discovery and application, also the development of energy meter put forward new requirements. Through the efforts of scientists, induction meter was born....
