Transformer platform electrical energy data acquisition terminal and data acquisition implementing method applying same

Abstract

The invention relates to a transformer platform electrical energy data acquisition terminal and a data acquisition implementing method applying same, in particular to an electrical energy data acquisition terminal which solves the problem that the existing data acquisition terminal can not continuously carry out data acquisition when a data acquisition interface has fault. The data acquisition terminal comprises a control circuit, a main station communication interface circuit, a wireless communication module, a power supply circuit, a Flash memorizer, a data acquisition interface circuit and a data acquisition expanding interface circuit, wherein the data acquisition expanding interface circuit and the data acquisition interface circuit work at the same time, and the data acquisition method is realized by applying the terminal; and after relation is established between the terminal and a main station server, a microprocessor controls the data acquisition interface circuit and the data acquisition expanding interface circuit to carry out data acquisition on an electricity meter. The terminal leads another data acquisition interface to be automatically switched when one data acquisition interface has fault, thus being applicable to the data acquisition of a transformer platform.

Description

technical field

[0001] The invention relates to an electric energy data collection terminal. Background technique

[0002] The transformer platform refers to the power conversion facility with transformers, lightning arresters, electric energy meters and other devices fixed in an insulating protective shell. Due to the lack of centralized distribution of transformer stations, wide use areas, large load differences, strong seasonal and time-period use, and a series of shortcomings such as inability to timely feedback damaged information, this brings great difficulties to data collection and management of transformer stations.

[0003] Traditional data collection is realized by manual reading and handwritten records. Therefore, the timeliness, accuracy and consistency of the collected data are poor. In recent years, the use of data collection terminals for data collection and remote transmission of electric energy meters can Effectively improve the accuracy of data. As far a...
