MSP430单片机的部分环境采集系统设计

摘要如今人们对生活环境的要求日渐提高，居室环境的适宜与稳定日益重要。环境参数超出舒适范围，将给人带来不适感，甚至引发疾病。然而实时掌控居家的环境情况并及时作出调控并不容易，为了实现对部分环境参数的采集，通过查阅相关文献和资料，本课题设计了一种基于 MSP430 单片机的部分环境采集系统。采集终端以 MSP430F14X 系列单片机为中心控制系统，并配有无线收发电路、液晶显示及报警系统。传感器输出的模拟信号经过信号调理电路后输送给单片机，由单片机自带的 12 位 AD 完成数据采集任务。该系统具有硬件电路简单、采集精度较高、实时显示等优点。系统稍加拓展还可应用于更多场合，具有一定的研究价值和实用价值。73791

Title The Design of partial environmental collection system based on MSP430 Single Chip

Abstract Nowadays, people's demand for living environment is increasing day by day, and the suitability and stability of the living environment are more and more important。 If the environmental parameters are beyond the comfort zone, it will give people a sense of discomfort, and even leads to diseases。 However it is not easy to complete the real time control of the condition of home and make timely regulation。 In order to realize the collection of partial environmental parameters, through access to relevant document literature, this topic provides a design of partial environmental collection system based on MSP430 single chip。 Collection terminal sets MSP430F14X series as the central control system, and is equipped with wireless transceiver circuit, LCD display and the alarm system。 Sensor output analog signal is sent to MCU through the signal conditioning circuit and the MCU which comes with 12 bit AD will complete the data acquisition task。 The system has the advantages of simple hardware circuit, high acquisition accuracy, real-time display and so on。 The system can be applied in more occasions and it has certain research value and practical value。
