Power utilization information acquisition device

Abstract

The invention relates to a power utilization information acquisition device, which comprises a power distribution system and a master station system, wherein the power distribution system comprises a power distribution cabinet, and the power distribution cabinet comprises a cabinet body and a concentrator arranged in the cabinet body. The power utilization information acquisition device is characterized in that the concentrator and the master station system are connected in a switched manner by adopting a plastic optical fiber channel and a quartz optical fiber channel, the concentrator is provided with a collector which is connected in series through a first plastic optical fiber, the collector and the concentrator form a series closed loop through the first plastic optical fiber, and the collector is connected to an electric energy meter which is connected through a second plastic optical fiber. The power utilization information acquisition device has the advantages that the whole power utilization information acquisition device realizes data communication through the first plastic optical fiber and the second plastic optical fiber, the average meter reading time of each house can be shortened to less than one second, the overall meter reading period is short, the real-time performance is high, the overall communication rate is high, the reliability is high, the bit error rate is low, the power consumption is low, the device is not subjected to influences of electromagnetic interference and does not externally generate radiation, the operation and maintenance cost can be reduced by 95% compared with the existing operation and maintenance cost, and the work efficiency is improved.
