说明：  单片机在检测和控制系统中得到广泛的应用, 温度则是系统常需要测量、控制和保持的一个量。 本文从硬件和软件两方面介绍了AT89C2051单片机温度控制系统的设计，对硬件原理图和程序框图作了简洁的描述。
(Single-chip in the detection and control system has been widely applied, the temperature is often the need for measurement systems, control and maintain a volume. In this paper, both hardware and software introduced AT89C2051 single-chip temperature control system design, hardware and procedures schematic diagram gave a concise description.)
