Design And Implementation Of Intelligent Management System For Agricultural Greenhouse Based On Internet Of Things

China is a large agricultural country, the population of which isone-fifth of the total population in the world. Only the high quality cropscan meet the food needs of people across country. China’s agriculture isenough to feed1.3billion people, even is exported overseas, but thefarming methods is still behind developed countries in Europe and America.Planting, irrigation and fertilization are still based on the experience,not precise in amount. In recent years, we can see strawberries, grapesand other anti-season fruits which are grown in the traditionalagricultural greenhouses. The reform of methods of production inlarge-scale will takes a long time, but which is easy to carry within asmall-scale. With the application of Internet of things in agriculture,the concept of Agriculture Internet of things appears. The hardware partof the Agriculture Internet of things mainly consists of temperature,humidity, light and other sensors and processors which are capable ofhandling big data. These hardware devices link to form a sensor networkvia short-range wireless communication. Short-range wirelesscommunication technology, including Bluetooth, WIFI, Zigbee, is widelyused in agriculture because of its convenient linking and low powerconsumption. If the index data read by sensors can only used by a singlecomputer, the remote control and remote monitoring can not be implemented.But the combination of sensors network and Internet can provideInternet-based greenhouse control by the use of sophisticated Webtechnology, which is the example of communications between people andobjects in Internet of things.In this paper, the smart system of greenhouse management based onInternet of things is researched based on sensor networks and Web-based technologies. The system consists of sensor networks and software controlsystem. Sensor network consists of the master control center and varioussensors via Zigbee protocols. The hardware control center communicates withmiddleware system via serial network interface converters. Middlewarecommunicates with hardware network via underlying interface, meanwhilewhich communicates with Web system via upper interface. The top Web systemprovides users with an interface to view and manage the hardware facilities.Administrators can view the status of agricultural greenhouse and issuecommands to the sensor through this system in order to achieve thetemperature, humidity and irrigation automated management. The main workis as follows:1. Research the current agricultural development of new technologiesand summarize the strong points and lacking of examples about theapplication of Agriculture Internet of things home and abroad. This paperalso proposes some new methods of agricultural greenhouse management.2. Complete the system requirements analysis and record and verify theuser expectations of the system. Determine the overall architecture andoverall design of the system, meanwhile design the database and give theE-R database model which can be converted to relational database tables.3. Divide the system function modules based on software engineeringideas to meet the requirements of low coupling between modules as possible,meanwhile design and implement every module by describing the algorithmby using flowchart and explaining the key code.4. Learn the JSP technology, database manipulation techniques and readand write operations of hardware to realize the system. Shows the schematicdiagrams of each functional module and complete the testing of system inseveral ways included middleware testing, link testing and compatibilitytesting.
