摘要
本文以AT89C52单片机为核心,设计了一种高精度,低价格的采样电路,完成了对现场6个点温度的采样。并且采用了现场总线技术,融入了CAN(ControlAreaNet)功能,性能可靠,开放型强,特别适合于工业现场温度的测量。
This article accomplished a high precision, low price sampling circui t's design, it's hardcore is AT89C52, can measure six temperature points of fiel d, and adopt field bus technology, CAN bus is joined in the system, is a very re liable, open system, is very fit for measure temperature of industry field.
