TI’s MSP430 microcontroller (MCU) and TMS320C2000(TM) digital signal controller (DSC) technologies help utility companies comply with environmental protection standards, minimizing power leakages while also advancing customer service with automatic outage detection and more accurate, timely readings. Based on TI’s TMS320F28015 DSC, MSP430F155 and MSP430FE427 ultra-low power MCUs and data converters, Incotex’s automated meter management (AMM) systems for electrical power distribution networks are optimized to deliver advanced efficiency capabilities to utility providers and end-users around the world.
Exemplifying Incotex’s energy efficient offerings, the company’s Mercury AMM system for electrical power distribution networks utilizes TI controller technology to provide automated data collection directly from consumer energy meters over power lines. This makes it possible for electrical utilities to easily detect and correct the location of energy losses. TI’s ultra-low power MSP430 MCU helps reduce the meters’ energy loss up to 30 percent through detection of electric energy loss and theft.
"Energy efficiency is paramount, and Incotex, together with TI, is committed to delivering technologies that enhance products and services while reducing power usage," said Batrakov Nikolay, technical manager, Incotex Co. Ltd. "Based on TI’s analog and digital solutions, Incotex’s meter management products demonstrate how technology can save energy and simultaneously improve business operations and the quality of service provided by utility companies."
With Mercury PLC AMR, utilities are able to introduce time of day pricing to better match prices to the cost of generating and delivering power. High-performance signal processing is critical to ensuring that two-way communications between the utility and meter are received and sent over power lines, as the infrastructure was not initially designed to handle communications traffic.
Incotex’s Mercury PLC AMR transmits data at up to 100 different frequencies in two directions, ensuring reliable and accurate transmission in high noise conditions.
The Mercury PLC utilizes TI’s F28015 DSC to simultaneously provide orthogonal frequency-division multiplexing (OFDM), which transmits multiple signals simultaneously over a single path.
Additionally, the TI DSC is used for phase shift keying (PSK) of the frequency hopping carrier, which varies the phase of the transmitted signal to convey information. TI’s DSC also handles OFDM signal processing through the implementation of Fast Fourier Transform calculations that analyze the frequencies contained in a sampled signal.
