【Abstract】 the technology about the Intelligent apparatus is a recently rising technology,it based on the computer and communica

tion. This paper introduces the related knowledge,developing state. the current achievements in the field are summarized. It analyzes the existing abuse of the electrodynamic meters charge nowadays. Intelligent power-convertors charge changes the past serving manner of manual work, avoids the disadvantages of the manual work, such as the wrong, liaking, and estimating reading, the great time lag, the low efficiency,the existing hidden safety problems. It not only saves the manpower and material resources,but also enhances the security.

this paper main content is Base on DL/Pt645 communication protocol of Intelligent power-convertors hardware design process.

Users will be at home for the cumulative and surplus electricity quantity. This systems main content involves the hardware chooses to use with design and the software to use with design.the system in consumption and stability is optinal effect through selection hardware.

【Key words】Intelligent apparatus, Intelligent power-convertor; microcontroller; remote meter-reading
