The invention discloses a method for compressing a communication message of a power utilization information acquisition system based on a hierarchical structure. According to the method, power utilization protocol data acquired by a user side is split into control type data and numerical type data. Most of the control type data is response to downlink interrogation information, so that the controltype data has strong randomness, errors are not allowed, mutual correlation cannot be found, and overall compression processing of the last layer is directly carried out; analyzing and classifying the numeric data, dividing the numeric data into four subclasses, and compressing the four subclasses by adopting algorithms such as a self-encoding network and differential encoding according to the distribution and related characteristics of the numeric data. Mutual rules exist in the numeric data. The correlation algorithm summarizes the rules and can carry out anomaly analysis and missing compensation on the data, so that the decompressed data of the receiving end is more reasonable and reliable, the stability of the electricity consumption information acquisition system is guaranteed, finally, lossless compression is carried out on the reintegrated data, the original rule of the transmission system is met, the efficiency is improved, and the time is saved.
Description
technical field [0001] The invention relates to the technical field of data compression, in particular to a method for compressing communication messages of a power consumption information collection system based on a hierarchical structure. Background technique [0002] In the daily operation of the power system, in order to effectively monitor and analyze the power consumption of users, the power company needs to collect and process the power consumption data of a large number of users. With the large-scale construction of smart grids, smart meters are gradually becoming popular instead of manual meter reading. Compared with traditional electric meter data, the data generated by smart electric meters has the characteristics of high collection frequency, large amount of transmitted data, and complex message structure. In the process of transmission and processing of a large amount of power data, the data distribution is uneven, so it inevitably brings data redundancy. Redu...
