TI satser på smart grid applikationer

Building on its commitment to bring more intelligence to the smart grid, Texas Instruments (TI) has announced new innovations at European Utility Week 2013 in Amsterdam. The new technologies allow smart grid developers to make the next generation of products for smart metering, grid infrastructure and communication systems, including smart homes and the Internet of Things (IoT).

Implementing an efficient smart grid consists of adding intelligence and communication to the utility distribution and transmission infrastructure, metrology devices and to connectable devices within a home or building. TI has developed industry-leading technology and tools with its complementary analog, embedded processing and connectivity portfolios that help developers create secure, economical and future-proof solutions for the smart grid and provide the flexibility to adapt a device for many countries, regions or standards.

New metrology solutions provide more performance, memory and cost options

TI has increased the availability of its field-tested metrology evaluation kits and grown its portfolio of metrology ICs with more memory, security and accuracy.

TI’s new polyphase metering kit based on the MSP430F6679 SoC provides developers with best-in-class accuracy, more integrated memory and advanced anti-tampering protection. These SoCs can achieve electricity measurement accuracy that meets or exceeds global regulatory requirements for smart polyphase e-meters including IEC 62053-22 and ANSI C12.20 Class 0.2 standards.

In addition, the large 512KB integrated Flash memory enables more sophisticated metering features like dynamic pricing tables, DLMS/COSEM or stacks for connectivity. The MSP430F6779 SoCs also include several advanced anti-tamper protection features that track meter tampering so utilities can easily reduce and prevent additional meter corruption.

In addition, a 128-bit hardware-accelerated Advanced Encryption Standard (AES) module speeds encryption time compared to a traditional software implementation, improving meter security, performance and reducing energy consumption.

TI's growing portfolio of Sub-1 GHz wM-Bus solutions is perfectly suited to support the massive smart water and gas meter deployments in France, Italy and the U.K. With the best selectivity and blocking performance on the market today, TI has developed a reliable MCU and RF combo solution with a longer range and more robust communication for difficult environments across Europe and Asia.

TI’s wM-Bus technology allows flow meter and sub-meter manufacturers to meet standards requiring batteries to last more than 15 years in the field. For more information about TI’s wM-Bus support, visit http://www.ti.com/euw-pr-wmbus-eu.

TI announces new ultrasonic flow meter with ultimate level of flexibility and accuracy

Featuring advanced software and robust hardware, TI’s ultrasonic flow metering solution contains the industry’s best combination of accuracy, intelligence and flexibility. The UFM-EVM solution is a complete ultrasonic flow meter reference design with advanced early leakage detection for gas, water and heat meters that balances the demands of power, accuracy and connectivity to provide an ideal starting point for developers in Europe and Asia.

This new ultrasonic flow meter design includes complementary analog and embedded technology from TI, including a next-generation analog front end (AFE) that can measure both the low amplitude and high frequencies of ultrasounds required for flow meter applications, an advanced time-to-digital converter (TDC) that precisely measures tens of picoseconds to meet rigorous flow metering industry requirements (EN 1434, EN 14236, CJ 128, OIML R 49), and ultra-low power expertise featuring the TPS62730 DC/DC converter and MSP430 microcontroller to ensure the meter remains in the field for many years without needing a battery change.
