Abstract:An Android-Based handheld terminal for wind turbine is developed for monitoring, maintance and setting of wind turbines. The handheld terminal communicates with the wind turbine’s main control system based on TCP/IP protocol and MODBUS protocol. And the monitoring, maintance and setting of the wind turbine is completed through touch operation in the interactive interface. At the same time, the data of all the wind turbines and users, of which the secret part is encrypted, are stored to the local database. The actual application shows that the Android-Based handheld terminal for wind turbine is feasible, effective and has flexible, portable, economical features.
