基于STM32的科学环境记录仪设计(论文14000字)
摘要：在实验室中，环境要素与实验操作有着非常密切的联系，准确的气象数据测量，对于实验室中所进行的操作以及化学物品的保存具有重要的意义，一些细微的环境变化可能会造成严重的损失。近年来，实验室中所使用的气象数据采集系统多数只是单纯的“移植”，这样采集到的数据不具有代表性且无法直观的看出时间段中的数据变化，并且传统的系统集成度低，功耗大，误差大，数据反映不够客观，无法保存等一系列问题。针对传统采集系统的问题，本文设计一种专门用于科学环境的气象要素记录仪。
    本文使用集成的气象数据采集系统来优化。通过使用主处理器STM32、温度传感器PT100,湿度传感器BMP180，气压传感器SHT10，模数转化模块作为硬件系统，将这些传感器进行集成，是采集的种类丰富。然后通过串口通信实现数据传输，pc机作为上位机对数据进行处理和存储，上位机软件系统以.NET为框架下的C#为开发语言，并采用数据库连接技术完成整个系统软件的开发。

Scientific environment recorder based on STM32
Abstract：In the laboratory, environmental factors and experimental operations are very closely linked, accurate meteorological data measurement, for the operation of the laboratory and the preservation of chemical substances is of great significance. In recent years, most of the meteorological data acquisition systems used in the laboratory are simply "transplanted", so that the collected data is not representative and can not visually see the data changes in the time period, and the traditional system integration is low , Power consumption, error, data is not enough objective, can not save a series of problems. In view of the problem of traditional acquisition system, this paper designs a meteorological element recorder specially designed for scientific environment.
This article uses an integrated meteorological data acquisition system to optimize. By using the main processor STM32, the temperature sensor PT100, the humidity sensor BMP180, the barometric pressure sensor SHT10, the analog-to-digital conversion module as the hardware system, the sensors are integrated and the collected types are abundant. And then through the serial communication to achieve data transmission, pc machine as the host computer for data processing and storage, the host computer software system to .NET for the framework of the C # for the development of language, and the use of database connection technology to complete the entire system software development.
