| Along with the rapid development of information technology, wireless control IT is increasingly popular inside the area. Wireless remote control is the use of wireless telemetry terminal equipment, replace the fieldbus, wireless control remote devices way.This paper discusses the realization of the use of Android software program written in C#program radio control and a mechanical hand to play the piano, which is an array of electromagnets to play the piano keyboard in the process. Not only can manually play, you can also automatically play music, not only short-range remote control can also be controlled. The purpose of this system is to make familiar with and master the principles of electronic devices and wireless control mechanisms familiar TCP/IP control principle, Arduino microcontroller, Android programming knowledge, C#programming knowledge, and so on. In the increasingly popular field of wireless control applications, it has a strong and important. Following the completion of the work, mainly after the end of the phone connected to Wi-Fi router, by writing the Android software interface buttons to control local or remote control panel to drive the solenoid operation, the control panel is connected after modification Wi-Fi routers and access into the broadband router connected to external networks, modification of Wi-Fi router from a remote phone receives radio signals through the serial port to pass control panel, control panel and then drive the relay electromagnet array drive accordingly hitting action, and can also be back to the video information.Concluded that no matter where we live, as long as we connect to the Internet, the use of the network can control a remote device that we want to control, very convenient, this simply can not be achieved before the looks of things can now be achieved, this technology can be applied to industrial production and family life, will bring great convenience to people’s production and life. |
