Intelligent multi-family energy meter Power Line Carrier set copy upwind smart meter energy meter current multifamily automatic meter reading technology on how to achieve high reliability, low cost data communication on topics encountered great difficulties. Modern communications technology has provided us with such as telephone lines, radios, power lines, twisted pair, fiber optic and other communications media to choose from. Low-voltage power lines across the country, without re-wiring, line maintenance, low cost investment and its advantages are so obvious deep for the power section favor. However, low-voltage power line communication caused by a poor environment, poor real-time meter reading, but this phenomenon is difficult to make electricity meter data management part as the basis for charging users. Advance fee card table after years of operational improvements, technology is relatively mature, and has been applied in some cities in China, effectively solve the energy billing and electricity arrears difficulties. Just buy a card meter users time and buy electric power is random, the user does not know the correct month of electricity, can not meet the power management section to keep abreast of the situation and line losses grid load statistical requirements; meter to be attacked causing the control system fails, raw data is difficult to obtain evidence finds that record easily lead to the restoration of electricity disputes, electricity charges governance in open loop control state. This card contains the integration developed energy meter, both advance fee and low-voltage power line carrier meter meter meter reading upwind, charge control using RF card for multi-user smart meter is to adapt to the modern power management requirements, centralized installation, small size , over-current capability, users of electricity sub-metering information. By ASIC can 39 or 13 single-phase three-phase electricity electricity accurate detection, door cycle, allowing electricity metering management more rigorous. Meter reading through computer networking and software management, reducing the manpower, resources, avoiding the wrong copy, copy and human power leakage occurs, prevent stealing behavior, intelligent power management, automation, scientific and provided the conditions. Has: 1, centralized installation, the complete elimination of theft, leakage behavior; 2 meter for quick, avoiding meter reading into the family and high-rise buildings on the stairs of trouble; 3, beautiful appearance, easy installation, low construction cost; 4, accurate measurement , technically sound, safe and reliable, automatic air switch located per household, according to customer need to install leakage, undervoltage, overcurrent protection devices; 5, with anti-interference ability, power-down memory data is not lost, small size, light weight , their low power consumption (only sibling induction meter 6%); 6, with a test input and output ports and clear function to facilitate the on-site inspection; 7, with remote automatic control off, the transmission function.
