Abstract
With the development of communications industries, have entered the telephone every household. With modern science and technology development, telephones for use in remote control technology is also increasingly used for life. This paper introduces a telephone line based Remote Control module design and implementation. In this paper introduces the design of the hardware, software design process, system testing. Embedded Remote Controller MCU used AT89S52 microprocessor, microcontroller system is the core of the device. By di telephone button DTMF signal decoders, use multiple recording and playing voice chip ISD2560 SPEECH tips with the serial EEPROM memory and CPU control for the X5045 to preserve the control code, can be the keys to amend the system password. Through telephone calls, access adopted in the corresponding input button on the remote charged with achieving the targets of control. Design of the appliance control system to identify the user of incoming calls and button input, Voice used to tell the user input corresponding operation, a user-friendly LCD control password changes. Relay through the middle to connect appliances.
