Description

A kind of Bluetooth cordless telephone of the mobile phone that can interconnect

Technical field

The utility model relates to a kind of Bluetooth cordless telephone, relates in particular to a kind of Bluetooth cordless telephone of the mobile phone that can interconnect.

Background technology

Traditional cordless telephone uses analog-modulated technology or digital modulation technique mostly.The operating frequency that the modulation technique of simulation is used is low, and domestic standard is 45～48MHZ, adopts the FM debugging, and confidentiality is poor, is disturbed easily, and speech intelligibility is low.Digital modulation technique uses 2.4GHz numeral frequency hop spread spectrum, is the conversion that realizes signal by digital data transmission between base and the handset.Have good confidentiality, anti-interference, the speech intelligibility height is the mainstream technology of cordless telephone at present.

Bluetooth is a kind of radio network technique, is proposed by computer maker and other manufacturer at first, and it has substituted cable, has realized connection between computer, PDA, phone and peripheral hardware, such as now the most frequently used bluetooth earphone etc.Bluetooth is the in-plant wireless communication technique of a kind of low cost, is operated in the open frequency range of 2.4GHz, and the Bluetooth transmission distance can be from 10 meters to 100 meters.Bluetooth technology is used high-speed frequency-hopping and advanced technologies such as time division multiple access, Gaussian Frequency Shift Keying, has low in energy consumption, characteristics such as transmission is reliable, speed is high, the multiple application of support, obtains a large amount of popularization and applications at present on mobile phone, and cost also reduces greatly.

Summary of the invention

At the deficiency of existing Cordless Telephone Technology, the purpose of this utility model is to provide a kind of Bluetooth cordless telephone, and can connect the mobile phone with Bluetooth function.

The utility model is achieved by the following technical solution:

A kind of Bluetooth cordless telephone of the mobile phone that can interconnect comprises: telephone set, mobile phone, Bluetooth cordless telephone, phone module, receiver, loudspeaker, Mike, bluetooth module, keyboard, antenna etc.Wherein phone module comprises ringing circuit, double-tone multi-frequency coding, frequency shift keying decoding, circuit for answering, hands-free switching etc.Bluetooth chip comprises microprocessor, can realize keyboard, caller identification and coding, ringing circuit control, power management.Described bluetooth module, power management, the ring module of being provided with on telephone set can realize the interconnection with mobile phone, the shared microprocessor of phone module and bluetooth module.Bluetooth cordless telephone connects the fixed line machine, and outlet connects the ring module; The input port is connected microphone and hands-free loudspeaker respectively with delivery outlet.Power management module is responsible for to bluetooth module and phone module power supply, and Bluetooth chip drives LCDs by parallel port, uses GPIO (general programmable input/output port) to connect keyboard.Bluetooth module is connected phone module by the MIC input port with the SPK delivery outlet, uses GPIO to control phone module simultaneously.

The utility model adopts the wireless transmission method of Bluetooth technology as cordless telephone, can connect the mobile phone with Bluetooth function simultaneously, and maximum can expand to 7 handsets.On the one hand, Bluetooth cordless telephone has good confidentiality, and is anti-interference, lamprophonia, and expansion is convenient, characteristics such as environmental protection; Have the mobile phone of Bluetooth function from being dynamically connected simultaneously, make mobile phone become the handset of bluetooth base, be user-friendly to.Can use as handset eliminating no mobile phone, reduce user's input with Bluetooth function.On the other hand, mobile phone and landline telephone can arbitrarily be answered fixed network or mobile network's incoming call, and mobile phone can choose at random and use fixed line circuit or mobile network to call, and is user-friendly to, and has reduced mobile phone and has answered the wireless radiation of calling.This technical support caller identification simultaneously, and can realize the functions such as backup of address list on the mobile phone.

Bluetooth standard that relates to and agreement comprise the core protocol of bluetooth: baseband protocol (Baseband), LMP Link Manager Protocol (LDP), logical link control and adaptation protocol (L2CAP), service search agreement (SDP).Application layer protocol: phone control protocol (TCS), synchronous applications agreement etc.The phone control protocol comprises TCS binary protocol and AT Command Set agreement, binary protocol has defined the control signaling of setting up voice and data call between bluetooth equipment, comprises that the controls such as transmission, call setup, end of calling of demonstration, the DTMF of caller ID all are to realize by this agreement.The synchronous applications agreement mainly provides the new management more synchronously of personal information management (PIM), comprises backups such as individual address, calendar, notice and record.

The running software of whole system comprises the core protocol stack and the certain applications protocol stack of bluetooth on the MCU of bluetooth module, the agreement of measured bluetooth has good compatibility and versatility.

Operation principle:

1, earlier Bluetooth cordless telephone and bluetooth cellular phone are set up link, and by checking.

2, in the mobile phone inlet chamber, mobile phone and Bluetooth cordless telephone are from being dynamically connected.Leave automatic disconnection.

3, when cell phone incoming call, Bluetooth cordless telephone becomes the bluetooth earphone or the hand free device of mobile phone, mobile phone and Bluetooth cordless telephone and the ordinary telephone set ring simultaneously that is connected thereof.

Comprise that with any terminal mobile phone all can receive calls, as shown in Figure 2.

4, when landline telephone is sent a telegram here, mobile phone becomes the earphone or the hand free device of Bluetooth cordless telephone, mobile phone and Bluetooth cordless telephone and the ordinary telephone set ring simultaneously that is connected thereof.

Comprise that with any terminal mobile phone all can receive calls, as shown in Figure 3.

During 5, with the mobile phone Outgoing Call, can select from the mobile network still is that landline telephone is transferred to, and can reach the purpose of saving telephone expenses.
