But the temperature is an analog, can not exchange information with the single chip directly. In principle, it is not difficult to transform the simulated temperature into the digital quantity, if adopting Proper technique .But gets the electric circuit more complex, the lost is more expensive, and other questions can be met. So it is very important for research of single chip temperature control.This article mainly introduced 8031 of series MSP-430、ADC10、MC14433、AD590、controllable silicon, which composed temperature measurement and control circuit、A/D transfer circuit、keyboard/LED display、signal magnifying circuit alarming circuit; Some important techniques in a design scheme of the software of the temperature by single-chip Microcomputer are introduced also, such as date processing software, control algorithms software.This system enhances real-time character of control system and control precision effectively, improves the automatic degree of furnace temperature and higher practice valueKey words: Single-chip Microcomputer, PID algorithm, Temperature sampling, Temperature controlp1EanqFDPw [Key word] MSP-430 SINGLE-CHIP TEMPERATURE CONTROL SYSTEM 目录 TOC \o 1-3 \h \u HYPERLINK \l _Toc1438 引 言 PAGEREF _Toc1438 3DXDiTa9E3d HYPERLINK \l _Toc534 第一章 绪论 PAGEREF _Toc534 4RTCrpUDGiT HYPERLINK \l _Toc2728 1. 1
