| At present, it is a problem in the traditional intelligent greenhouse of facilities agriculture that users are unable to deploy the “center computer” or the difficult wiring. Along with the popularity of Android smartphones and the development of WIFI technology, the use of mobile portable devices wireless communication technology to replace the "center" is the development direction of greenhouse environment parameter control system.This paper is based on the existing greenhouse environment parameter control system, and an Android mobile client application is developed, which can achieve the information exchange between the Android smartphone and the 485-WIFI module through the WIFI signal. The information of greenhouse environment parameters and greenhouse equipments can be stored in the phone’s SD card. The Eclipse is adopted as the developing tools and Java as the development language At first, a research is made on the domestic and foreign development present situation, such as the intelligent greenhouse control system, WIFI, and the Android, and the overall design scheme of the system is given, including hardware and software. Then, this paper focuses on the study of the Android client application. The Android client software has been carried on the detailed design, including function design(login module, the greenhouse data query module, equipment control module, historical data acquisition module, information setting module, et al), communication mode and communication protocol design, data design for receiving processing and storage, the processing of connection between client and the network connection module, UI design, etc. At last, the functional testing of the Android client is performed. The test results are consistent with the project goal, that using the Android smartphone instead of the “center computer” to control the intelligent greenhouse. It provides a novel, low cost, convenient implementation plan for intelligent greenhouse control system. |
