为了实施有效的温室环境控制,提出采用无线技术组建温室大棚温湿度数据采集系统的方案.该系统采用了主从式分布结构,集计算机技术、微控制器技术、智能传感器技术和无线通信技术于一身,能根据用户设定自动采集现场的数据,并经过无线传感网络传送到上位机中,上位机软件具有数据存储、分析和报表打印等功能.实践证明该系统的应用可降低布线成本,对温室的温湿度进行实时监测,有助于提高农作物的产量.%In order to control the environment effectively, a data acquisition system of temperature and humidity based on wireless technology was proposed. The system adopted a master-slave distribution structure and made use of computer technology , microcontroller technology, smarf sensor technology and wireless communication technologies. It can collect data and transmitt them to host computer through wireless network. The host computer software has the function of data storage , analysis and form printing. Application of the system shows that the cost of wiring can be reduced,temperature and humdity can be monitored in real-time , and crop production can be improved.
