Title Design of data acquisition system based on Internet of things    monitoring system design                         

Abstract

With the development of computer and Internet, Internet of things is regarded as a gradually growth would eventually become mature set intelligent recognition, positioning, tracking and monitoring and management is one of a network, a wide range of benefit to living in the 21st century, the people。 

The system is based on the classic MSP430 MCU, and it realizes the temperature data acquisition and monitoring system based on Internet of things。 As the design of monitoring and control system for the whole system, the graduation design is mainly responsible for the implementation of temperature monitoring system of human-machine interface in the VC + + programming environment, the main function of the interface is through the RS-232 serial port accept uploaded by MCU temperature data, the data will be stored in the Access2000 database, and realize the temperature history query function and temperature data real-time curve fluctuations display。 

This paper introduces the working principle of the related control and the realization method of the software part, and gives the experimental results at the end of each chapter, which proves the correctness and operability of the scheme。 It is proved that the design is stable and the interface is simple and practical。 It can be used for reference for the design of other PC monitoring system。
