基于ARM7的温度采集及控制系统

目前的温度采集及控制系统内部芯片采用单片机，采集终端硬件功能简单，芯片性能低，软件设计复杂，终端设备软件无底层操作系统，任务调度需由程序设计者设定，系统升级困难。基于ARM7的温度采集及控制系统运用Samsung公司的ARM S3C44B0X01硬件平台，配置嵌入式μCLinux操作系统，选用两端式温度／电流传感器AD590，构成的温度采集及控制系统。具有高精度多路采集，更简单的软件设计，方便的软硬件功能修改、扩充、升级等优点，满足了系统实时性需求，有效地解决了温度采集及控制系统中的问题。

Temperature Gathering and Controlling System Based on ARM7

Current temperature gathering and controlling system＇s internal chip is single chip microcomputer , gathering terminal function simply , chips performance low , equipments having no underlying OS, task scheduling needing to be software design complexity , the terminal set by programmer and system upgrading difficult. Using hardware platform of the Samsung Corporation ARM S3C44B0X01, installing embedded μCLinux OS and choosing two-terminal temperature or electric transducer AD590 to make-up a temperature gathering and controlling system, The system has excellence of high degree of accuracy multiplexing acquisition, more simple software design, convenient soft and hardware function modifying, enlarging and upgrade etc. , which satisfies real-time needing and solves the problems in temperature gathering and controlling system efficaciously.
