Massive Chinese Meter Project Uses ST Chips

Geneva, Switzerland: The largest-ever automatic meter reading (AMR) effort to be undertaken in China will employ power-line transceivers from STMicroelectronics. The power-line communication modules based on STMicro’s highly integrated chips have been selected in combination with other conventional communication technologies, such as RS-485.

The anticipated multi-utility metering system will enable China National Petroleum Corporation (CNPC), the country’s largest integrated oil and gas company, to remotely collect and manage consumption of water, gas, heat, and electricity in more than one million households across China.

STMicro’s ST7540 power-line transceiver chips are at the heart of power-line communication modules supplied by Shenzhen B&G Technology Development (B&G), one of the major system providers for the CNPC project. These modules will collect user consumption data from different meters into data concentrators, which are remotely managed by the central Management Information System.

Compliant with international standards, including the European CENELEC EN50065 and the US FCC part 15, the ST7540 has been also approved for compliance with the local Chinese standard DL/T 698-1999.
