基于单片机的无线多路数据(温度)采集系统的设计与实现(毕业论文)详解.doc

摘要 由于数据采集系统的应用越来越广、其所涉及到的对信号的测量方式和涉及到的信号源的类型也将越来越多、因为对测量的要求也就越来越高，现在国内已有不少用于数据的测量与采集的系统，可很多系统存在着功能单一、采集速率比较低、操作非常复杂，并且对测试的环境要求较很高等问题。人们急切需要一种应用范围广、价格低廉的数据采集系统。 在分析了各种类型单片机的特点及其与PC机的各类通信技术的基础后，本人设计了由单片机控制的温度采集系统，并且通过串口通信的方式实现了单片机与PC机间的通信，实现了数据传送并将数据在PC机上进行显示或存储，完成了此次设计。 基于单片机的多通道的温度数据采集系统是由将来自温度传感器的信号进行放大、滤波、采样保持等分步处理之后，输入到A／D转换器转换为数字信号后由单片机进行采集的，然后再利用单片机与PC机之间的通信将数据传送至PC机进行数据的存储处理及显示等，实现了数据的采集与处理等，此设计可广泛应用于工控、仪器仪表、机电智能化及智能家居等诸多的应用领域。 联系扣扣：2825772782 关键词：单片机；温度数据采集；多通道 Abstract Since the wide range of data acquisition system, which involves the measurement signal and the type of signal source more and more, Surveyors are increasingly high requirements of the domestic now have a lot of data acquisition and measurement system But there are many single function systems, collecting less access, low collection rate, complicated operations, and the demands of the test environment and other issues．It requires abroad scope of application, high reliability and low-cost data acquisition system． Based on the analysis of the characteristics of different types of SCM and SCM and PC communication technology, SCM control of the collection system designed and adopted MCU serial communication between PC and communications, Data transmission and display of data stored on the PC．Single completed the multi-channel data acquisition system design and implementation. Based on SCM′s multi-channel data acquisition system is adopted will come from the sensor signal amplification, linear filtering, After processing maintain synchronous sampling, which converted to digital signal input A/D conversion by SCM Acquisition, Then, SCM and PC to PC communications data to the data storage, post-processing and display. a powerful data processing, visual shows, friendly interface and high performance-price ratio, a wide range of features. can be widely used in industrial control equipment, instruments, and electrical engineering integration, intelligent home and many
