A remote exploration and control system has been developed using web Application, web server, database, GSM network, and Android mobile phone. Web application is used to control remotely an Android mobile phone and electrical devices connected with the mobile phone. Firstly, command is sent from the web Application and saved in database. The Android mobile phone reads the sent command from database and performs predefined procedure to execute the command and hence, generate outcome due to execution of the command. Thus, this system can be used as an exploration and control system because remote mobile phone automatically implements command like capturing picture and upload the captured picture to the server and control electrical devices. Command is implemented to capture picture automatically of the surrounding location and upload it to server. It can also send automatically GPS location of the mobile phone to server's database. So, it can be used to detect the device's geographical location and collateral condition. Hence, it can be used in monitoring as well as in security system. Finally, command is implemented for generating DTMF tone signal on Android phone. A DTMF detection circuit, interfaced with mobile phone, can automatically detect the DTMF tone signal and generates 4 bit digital code output. This digital output code can be utilized to control any electrical device. |
