Embodiment Construction

[0039] The present invention will be further described below in conjunction with the drawings and embodiments.

[0040] Such as figure 1 As shown, an STS split-type electric energy meter based on low-power carrier communication mode includes a concentrator, a main meter and an indoor unit;

[0041] The concentrator includes a main controller one and a peripheral module one and a carrier module one connected to it. The two ends of the carrier module one are respectively connected to the live wire inlet and the neutral wire inlet, and the carrier module one and A coupling capacitor C1 is connected between the incoming lines of the live wire, and the incoming end of the live wire is the relay input end of the main meter. The concentrator reads the main meter by connecting the coupling capacitor C1 to the incoming end of the live wire;

[0042] The main meter includes the second main controller and the metering module, the second peripheral module, and the second carrier module connecte...

Abstract

An STS (standard transfer specification) split electricity meter based on a low-power-consumption carrier communication mode comprises a concentrator, a main meter and an indoor unit. A carrier signal of the main meter is coupled to an input / output end of a relay through two capacitors C2 and C3 to communicate the concentrator and the indoor unit. A carrier module of the indoor unit is a main module. A carrier module of the main meter is an auxiliary module. After the main meter is switched off due to overdue charge, a power management module of the indoor unit switches to a battery supply mode, and 12V power is provided for carrier communication. Hardware of the indoor unit comprises a low-static leak current part; by the use with the interlocking auto-switching / time division subarea supply technology, the life of a battery is prolonged; after mains supply is down, a system can seamlessly switch to the backup battery for power supply; additionally, during the modules transmitting data, transmitting power and selected channels are dynamically adjusted according to receiving signal strength, signal-to-noise ratio and bit error rate of each channel, and transmitting power is maximally reduced at the premise of ensuring reliable data transmission.

Description

Technical field [0001] The invention belongs to the field of smart grid communication, in particular to an STS split type electric energy meter based on a low-power carrier communication mode. Background technique [0002] At present, the STS code meter: Key-pad Prepayment Energy Meter (Key-pad Prepayment Energy Meter), is an energy meter that uses virtual media-code-for information exchange. The code refers to a set of digital tokens, such as 28375872373168543423. Through the payment system, a set of unique code (Token) is generated, and the user inputs this code (Token) into the meter (Meter) through the key-pad, and the meter is decoded in the meter according to the agreement. Finally, complete the power purchase or recharge. Because the coded prepaid energy meters that comply with the STS specification have a unified standard, and have been tested and certified by the STS, and the standardized security module encryption algorithm is used, all coded prepaid meters that comply...
