Design Of Bluetooth Fixed Telephone On Computer Contral

With the rapid development of wireless communication technology,the mobile phones is becoming common in daily life,It in satisfying people's rapid,efficient,convenient access to information services at the same time also brought a series of problems.Mobile phones can be carried around,but they may be weak,weak or even in remote areas where there is no signal.Fixed telephone in recent years,although did not achieve a greater development,due to its formality,low radiation and other advantages it is still widely used.The design of Bluetooth telephone based on computer control is mainly to design a serial circuit,the computer,fixed telephone,connect Bluetooth headset,computer realization of fixed telephone dialing and call display function control also can use Bluetooth headset fixed telephone calls,the main advantage is that it does not change the internal structure and the fixed telephone circuit it can realize the control of fixed telephone.The main task of this design is based on in-depth understanding of the fixed telephone and Bluetooth headset on the working principle,the hardware using STC12C5A60S2 MCU as control core,using Bluetooth chip Blue Core5-Multimedia External connect Bluetooth headset and the fixed telephone,to achieve control of fixed telephone dialing and caller ID function computer with HT9200A and HT9170D chip,USB transceiver function the controller use PL2303HX chip built-in computer and telephone connection.The software part Modular programming ideas,the use of Keil as a programming environment C language as a programming language to achieve the control of the overall circuit.
