Abstract  In this study, a multi-purpose remote controller based on Bluetooth mobile phone (MRCBMP) is proposed to provide users for a convenient control interface.  The IR, RF and Bluetooth modules are integrated into the microcontroller module cooperated with Bluetooth mobile phone by Bluetooth module.  By MRCBMP, users can control IR, RF and Bluetooth controlled objects without the numerous conventional remote controllers.

Introduction(1/3)  With the more household appliances entering everyone’s home today, the more and more remote controls are created to be accompanied with increasing variety and brands of appliances.  The numerous remote controls make the operations inconvenient, because user needs to switch from one control to another when user wants to control different appliance.  In the commercial market, the called universal controllers are promoted to reduce increased the amount of remote controllers.

Introduction(2/3)  At present, traditional mechanical keys are still applied for the entrance mechanism. For the advanced security reason, inputting the passwords or using induction technologies are mainstream applications.  For example, the RFID is an induction application. The RFID reader induces the tag and read the data from tag to control entrance mechanism.  Sometimes, users may forget to bring the RFID card with themselves or passwords, so they are kept out of the door.

Introduction(3/3)  In this work, three wireless control interfaces hardware including IR, RF and Bluetooth are integrated in a portable mobile phone.  We can input the control data of the different brands and types into the mobile phone. The data will be stored in the memory of mobile phone.  The users can control different controlled objects without changing the controller hardware in the mobile phone.  Compared with traditional universal controllers, this work provides more flexible extension.

Conclusion (1/2)  This study has proposed a multi-purpose remote controller based on Bluetooth mobile phone.  IR, RF and Bluetooth wireless communication technologies ate integrated into MRCBMP design to provide users for a convenient control interface.  By MRCBMP, users are able to control IR, RF and Bluetooth controlled objects without numerous conventional remote controllers.

Conclusion(2/2)  The suggestions of future works are given as follows. We will integrate microcontroller module, Bluetooth module, IR module, RF module and Bluetooth module into a chip to reduce the hardware size of MRCBMP.  Besides reducing size, we will set up a controlled object database with common household appliances and daily applications.  If users buy a new household appliance, they can download its control data from internet to change their controlled object in the HWCP without any additional cost.
