基于ATT7028A的载波智能仪表设计

Design of Carrier Energy Meter Base on ATT7028A

本文提出了基于高精度计量芯片ATT7028A载波智能仪表的设计方案。完成了方案的硬件与软件设计,重点进行了载波部分的设计及测试。本智能仪表不仅在实验室环境下进行了成功的载波组网通信测试,而且已经挂网运行,运行性能稳定可靠。本设计方案在电力线存在严重干扰情况下,提高了载波通信成功率,实现了自动抄表功能。

This article proposed a design proposal of Carrier Energy Meter based on the High-precision measurement chip ATT7028A.In this proposal the hardware design and software design have been elaborated.The main focus of the article is to introduce the design and network test of the carrier part.Under the environment of laburatory,the Carrier Energy Meter not only has been carried on the carrier network correspondence test successfully,but also has been put into practice with stable and reliable performance characteristic.When the power line was disturbed seriously,this design proposal raised success ratio of the carrier communication and achiered the automatic meter function.
