摘要 随着时代的发展，越来越多的智能型电子和机械产品出现在我们的生活、学习和工作中，小至手机、计算器、家用电器、掌上电脑以及鼠标等电脑配件，大到导弹的导航装置，飞机上各种仪表的控制装置等等，那么是什么使他们有了如此强大的功能？答案很简单——单片机。是单片机，它把我们带入了智能的时代。目前单片机渗透到我们生活的各个领域，几乎很难找到哪个领域没有单片机的踪迹。因此，本课题便就其一个方面对单片机进行深入研究，设计开发利用SPCE06IA单片机实现多路温度采集。介绍了数字式多路温度采集系统的设计过程，包括硬件设计和软件设计。本设计采用SPCE061A单片机作为主控制器，采用LED键盘模组作为键盘输入和显示单元，通过一线制温度传感器DSl8B20实现温度的采集。该系统充分利用了SPCE061A的资源，发挥了芯片的性能，是SPCE06A在数据采集方面的典型应用。 关键词：SPCE061A ；DS18B20 ；多路采集；语音 Abstract With the development, more and more intelligent electronic and mechanical products in our lives, learning and work, as small as cell phones, calculators, home appliances, handheld computers and computer accessories such as a mouse, large missile Navigation devices, aircraft control devices of various instruments, etc., then what is so powerful that they have a function? The answer is simple - single chip. Is a single chip, which took us into the intelligence era. SCM infiltrate present in all areas of our lives, which is difficult to find the field almost no trace of the microcontroller. Therefore, this issue will be one aspect of their depth study on the single chip, single chip design and development of multi-use SPCE06IA temperature acquisition.The design process of a multi-channel digital temperature acquisition system is introduced in this paper,including hardware design and software design.This design uses SPCE061A MCU as the main controller,a keyboard LED module as a keyboard input and display units,one-wire temperature sensor DS18B20 as temperature acquisition units.The system takes full advantage of the SPCE061A resources,displays the chip’s performance,is a typical application works in data acquisition for SPCE061A.
