Abstract

The invention discloses a smart city power big data information collection system, which includes a front-end acquisition module, a signal transmission processing module and a host computer. The front-end acquisition module includes an electric quantity sensor for collecting electric energy data, and the detection signal of the electric quantity sensor passes through an A / D converter. It is converted into a digital signal and sent to the controller; the signal transmission processing module includes a frequency modulation noise reduction circuit, a feedback stabilization circuit, a bias isolation circuit and a wireless transmission unit. Frequency selection, and the use of resonant notch can well eliminate the harmful noise generated inside the system, which greatly ensures the accuracy of the acquisition signal transmission process, and the feedback stabilization circuit effectively suppresses the fluctuation of the signal when the frequency modulation and noise reduction circuit is working. Power data collection is fast and accurate, data transmission reliability is high, and the system has strong anti-interference ability, which effectively improves the accuracy of intelligent management and control of electric power big data information.

Description

Technical field [0001] The present invention relates to the field of smart urban data acquisition, in particular to smart urban electricity data information acquisition system. Background technique [0002] Smart cities are smart cities, and smart cities can effectively integrate the resources of the city to further enhance the city's productivity and service capabilities. The capabilities that smart cities must have information, including information collection, information transmission, information throughput processing, interaction of information, to build the basis of intelligence. At present, as the city's power pipe network is complete, the automation level of power system is continuously improved, which relies mainly on the front-end acquisition of electrical energy data to obtain load capacity and health status of each node of power network, and utilizes wireless transmission technology to achieve power data. Remote control diagnosis. However, during the remote transmissi...
