| Nowadays,the boundaries between disciplines are less strict,the trend to a higher level of integration,the open an interdisciplinary,application research based on the teaching way of learning is necessary.During the master study at the school to carry out research learning curriculum,how can point into the research class,students interested in how to make students master more complex and has a certain depth of Internet related technologies,how to through the comprehensive example for students to understand the Internet of things networking development process must be thinking about is present.Under the strong support of mentors and school,I designed and developed a set of simulating the real working process of sand-intelligent agricultural control system of teaching.The system using the IEEE802.15.4/ZigBee wireless network communication technology,the Internet of things technology,sensor technology,GPRS technology,ZStack open source protocol stack,the gateway embedded Linux system,QT development framework,C,C + + language,and the frontier for professional teaching CC2430 development platform,and easy to design the intelligent teaching sand table,to make it act as an automatic sensor,automatic adjustment of crops "housekeeper",can achieve unsupervised,automatically adjust the temperature and humidity inside the greenhouse,light,the concentration of carbon dioxide,and provide the passive infrared sensor automatically broadcast crops is introduced,and the remote control function.Intelligent agricultural teaching sand table set of innovative,practical,low cost,etc,which can be promoted by way of inquiry learning a good auxiliary teaching,greatly to mobilize the students' initiative and creativity,understanding and using of knowledge in this field have the effect of the catalyst,the students can further experience on the basis of practice,and even to disassemble,restructuring,and secondary development and received good teaching effect. |
