The invention relates to an intelligent automatic meter collection and reading system used for a low-voltage area. The system includes: a plurality of intelligent data collection units, a plurality ofintelligent data concentrators, and a main station system. The intelligent data collection units are connected to the intelligent data concentrators in order to collect user electricity data at certain frequency and output the user electricity data to corresponding intelligent data concentrators; the intelligent data concentrators are also connected with the main station system through a GPRS communication unit in order to concentrate the user electricity data and upload the user electricity data to the main station system through GPRS public wireless network; the main station system is usedfor data information influx and statistic analysis of the user electricity data. The system can reduce the calculation load of a data center server and achieves automatic collection, transmission, processing, decision making, statistic analysis and database management to the user electricity consumption, achieves concentrated management of distributed users, can save large quantity of manpower andresources, and greatly improves intelligent automatic management level of power enterprise.
Description
technical field [0001] The invention belongs to the technical field of electric power automation, and relates to an intelligent centralized reading system, in particular to an intelligent centralized reading system used in a low-voltage station area. Background technique [0002] With the continuous expansion of the power network and the rapid development of the number of users, the management model of one household and one meter has been popularized in China, and the workload of meter reading for power supply companies has doubled. The traditional manual meter reading is time-consuming and laborious. Timeliness and accuracy cannot be guaranteed, which can no longer meet the scientific management of power companies' timeliness for meter reading. Therefore, using certain equipment to make these meters form a meter reading system and automatically read them has become an important aspect of the technical transformation of the customer service department of the power supply com...
