Abstract

The invention discloses a smart city power big data information acquisition system, which comprises a front-end acquisition module, a signal transmission processing module and an upper computer; the front-end acquisition module comprises an electric quantity sensor for acquiring electric energy data, and a detection signal of the electric quantity sensor is converted into a digital quantity signalthrough an A / D converter and then the digital quantity signal is sent to a controller; the signal transmission processing module comprises a frequency modulation noise reduction circuit, a feedback stabilizing circuit, a bias isolation circuit and a wireless transmission unit, the frequency modulation noise reduction circuit uses the band-pass filter principle to accurately select the frequency of the pulse frequency signal, and uses the resonance notch to well eliminate the harmful noise generated in the system; and the precision of acquired signal transmission process is greatly ensured. Afeedback stabilizing circuit effectively suppresses fluctuation generated by signals when the frequency modulation and noise reduction circuit works, electric energy data acquisition is rapid and accurate, the data transmission reliability is high, the system anti-interference capability is high, and the intelligent management and control precision of electric power big data information is effectively improved.

Description

technical field [0001] The invention relates to the technical field of smart city data collection, in particular to a smart city power big data information collection system. Background technique [0002] A smart city is a smart city. A smart city can effectively integrate and utilize the city's resources to further improve the city's production efficiency and service capabilities. The capabilities that a smart city must have include information collection, information transmission, information throughput processing, and information interaction capabilities, in order to build the foundation of smart capabilities. At present, with the improvement of the laying of the urban power pipeline network, the degree of automation of the power system continues to increase. It mainly relies on the front-end collection of power data to obtain the load status and health status of each node in the power network, and uses wireless transmission technology to realize power big data. Remote c...
