Embodiment

[0025] see figure 1 , an intelligent power acquisition system, including smart energy meter, data collector, power line modem II, low-voltage power grid, power line modem I, concentrator, modem II, data communication network, modem I, and remote server meter reading center. In the case of no power outage, the power consumption status of the electrical equipment is automatically monitored continuously or periodically, and the collection, transmission, background processing and storage and forwarding functions of the power consumption data under the online monitoring state are realized. Among them, the data collector is embedded on the smart meter to automatically collect, process and send the electricity consumption information and charging information of the monitored electrical equipment. The data collector converts the collected electricity consumption data into The data format suitable for power carrier transmission is output and transmitted through the low-voltage power ne...

Abstract

An intelligent electric quantity acquisition system comprises an intelligent electric energy meter, a data collector, a power line modulator-demodulator 2, a low voltage power grid, a power line modulator-demodulator 1, a concentrator, a modulator-demodulator 2, a data communication network, a modulator-demodulator 1 and a remote server meter reading center. The data collector is embedded in the intelligent electric energy meter, converts the acquired power consumption data into a data format suitable for the electric power carrier wave transmission via the power line modulator-demodulator 2 and outputs and transmits via the low voltage power grid, the data of the low voltage power grid carrier wave transmission is carried out the data format conversion via the power line modulator-demodulator 1, and the data after the format conversion is transmitted to the concentrator. The concentrator is equipped with a Flash memory, and is used to pre-store the data transmitted by the data collector according to a set time interval to be convenient for the data backup. The intelligent electric quantity acquisition system of the present invention has the advantages of good reliability, accurate data, strong adaptability, complete function, small module size and low power consumption.

Description

technical field [0001] The invention relates to a power collection system, in particular to an intelligent power collection system applied in the field of power supply and distribution. Background technique [0002] With the rapid development of electric power construction, the scale of the power grid continues to expand. In many cases, the construction and equipment maintenance of the power grid are becoming more and more frequent. The transmission line as the power transmission link has the characteristics of long distance, large dispersion, difficult to patrol and maintain. [0003] Automatic meter reading system refers to a new technology that uses communication and computer network technologies to automatically read and process meter data. The development of automatic meter reading technology is a need to improve the level of property management, and it is also an inevitable need for the rapid development of network and computer technology. Using automatic meter read...
