摘 要 在仓库的货物的管理中，防潮、防霉、防腐、防爆是衡量仓库管理质量的重要指标，它直接影响到储备物资的使用寿命和工作可靠性。为保证日常工作的顺利进行，我们需要实时知道温湿度的具体变化，因此首要问题就是加强仓库内温度和湿度的监测工作。人工测试方法费时费力、效率低、测试的温度湿度误差大随机性大，而且库区的面积越来越大，因此我们需要一种造价低廉、使用方便、测量准确、传输能力强和通信距离远的监控系统来有效地对仓库货物进行监管。 本课题是在ARM控制系统的基础上，利用DS18B20温度传感器、HS1101湿度传感器、AY-nRF905和S3C44B0，通过SPI总线方式进行AY-nRF905与S3C44B0的数据通信。同时，通过DS18B20温度传感器和HS1101湿度传感器在嵌入式系统的控制下来实现工业现场温度和湿度数据的采集，将该温度和湿度数据送到AY-nRF905无线收发模块予以发射出去。在远程进行接收并实现报警、显示温度和湿度以及被送到上位机。 关键词:ARM DS18B20 HS1101 NRF905 监控系统 Abstract In the management of warehouse goods ,moisture, mildew, corrosion, explosion are important indicators to measure the quality of warehouse-management. They directly affect the life and reliability of the stockpile. In order to ensure the daily work is carried out smoothly, we need to know the real-time and specific changes of temperature and humidity . So the first problem is to strengthen the monitoring of temperature and humidity inside the warehouse. Manual testing method is time-consuming and low efficiency, large randomness of the test temperature and humidity errors, and the area of the reservoir area is more and more large. Therefore, we need a low cost, easy to use, accurate measurement, transmission capability and the communication distance monitoring system to effectively regulate the storage of goods. This topic is about how to use the DS18B20 temperature sensor, the HS1101 humidity sensor, the AY-nRF905 and S3C44B0 and AY-nRF905 S3C44B0 data communication through SPI bus based on the ARM control system. DS18B20 emperature sensor and HS1101 humidity sensor in the control of embedded systems down industrial site temperature and humidity data collection, the temperature and humidity data to the AY- nRF905 wireless transceiver module to be transmitted out. Receive and display the temperature and humidity as well as being sent to the host computer in the remote Keywords : ARM DS18B20 HS1101 NRF905 Monitoring system 目 录 摘要 I Abstract II 绪论 1 1 温湿
