Real-time Clock and Temperature Detection System of ESR Analyzer Based on C8051F SOC

本文设计了一种应用于血沉自动检测,基于SOC的C8051F单片机,结合SMBus总线技术和一线总线技术的实时时钟、温度检测系统。系统采用I2C总线的智能日历时钟芯片PCF8563提供时钟信息,应用一线总线数字温度传感器DS18B20检测温度,利用液晶屏实时显示。该系统具有结构简单、功耗低、可靠性好、可移植性强等特点。

This paper introduces a real-time clock and temperature detection system of ESR analyzer with the SMBus bus technology and 1-wire bus technology. C8051F microprocessor is used as main controller. The system uses a calendar clock chip PCF8563 with I^2C interface to offer time and a programmable resolution 1-wire digital thermometer to detect temperature. The data are real-time displayed in LCD. This system has features of simple structure, low power consumption, good reliability and powerful transplantable capability.
