Design And Implementation Of The Modern Agriculture Exhibition Center Based On Wireless Sensor Networks

With the continuous development of scientific information technology and artificial intelligence,such subjects as computer,automatic control,communication,microelectronics and other disciplines gave birth to a new monitoring and control network,that is,wireless sensor network(Wireless Sensor Network,WSN).Advanced technologies like agricultural networking have broad application prospects in China's agricultural and forestry fields,especially,they have a great promote value and practical significance in precision agriculture,intelligent irrigation,soilless cultivation and environmental data monitoring.Modern Agricultural Exhibition Center is the window of the enterprise and the government,which displays the agricultural science and technology level to the public.Therefore,in order to enhance the body feel,and play its innovative initiative to increase passenger capacity,convenience and high-tech methods are necessary.The existing farm exhibition hall is mainly artificial explanation,rarely equipped with intelligent robots.Even if the robots in the center of the exhibition hall are mostly entertainment robots,they are no close integration with the agricultural system.This article facing Modern Agricultural integrates the self-designed tour guide robot with agricultural display platform,which increases the sense of science and technology,improves the quality of the tour guide,and also reduces the labor to explain.This design takes full account of the product's safety,stability and low power performance,industrial-level reference and uses RTOS,LINUX operating system and LWIP network protocol to design.Firstly,the paper analyzes the demands of agricultural exhibition hall,puts forward the design criteria,and then designed the system according to the demand and design criteria.This paper designs a modern agricultural display center based on wireless sensor network.Followings are the three systems:ARM master system,plant cultivation system and guide robot system.ARM master system has video surveillance,image acquisition,GPRS,wireless transmission,local database,sound and light alarm and other functions.It can upload the datum of plant cultivation system,tour guide robot system to the cloud server through the WIFI wireless network.Plant cultivation system is mainly based on the soilless cultivation of' lettuce and the use of high-precision sensors to collect light intensity,gas concentration,air temperature and humidity,nutrient concentration and other parameters of the plant for intelligent cultivation.As a human-computer interaction intelligent terminal,the tour guide robot system can lead visitors to visit the agricultural exhibition hall.It has the functions such as the speech of crop knowledge,speech recognition,action recognition and WIFI receiving server command.Besides,the self-balancing of two-wheeled robot has been studied and designed in this article.Finally,the modules of the system mentioned before are designed and the function of the module is tested.Besides,the system is integrated and therefore the scheme of modern agricultural exhibition center based on wireless sensor network is realized.Also,through the system intermodulation,the three systems of mutual communication and control has been achieved;thus,the feasibility of this program is successfully confirmed.
