The content of the invention
In view of the problem of prior art is present and defect, the present invention provides a kind of call adapting system, and the system is a kind of
To realize the protection to " internal number ", the communication switching system that number is hidden and designed is realized.
The present invention adopts the technical scheme that：One kind call adapting system, it is characterised in that：The system is penetrated provided with two
Frequency module and a control module, two radio-frequency modules are the first radio-frequency module and the second radio-frequency module, on two radio-frequency modules
SMA interfaces are respectively equipped with, by the external Multi-standard multi-band omnidirectional antenna of SMA interfaces, are carried out respectively with calling party and callee
Communication；Control module is provided with FPGA, STM32 single-chip microcomputer, power connector, the PCM signals of two radio-frequency modules respectively with
FPGA is communicatively coupled；The UART signal of two radio-frequency modules is connected with STM32 single chip communications respectively；FPGA and STM32
Single chip communication connects；The system connects host computer by USB port；Portable power source built in system and the power supply of control module connect
Connect device connection.
Two radio-frequency modules of the present invention be respectively equipped with can power down plug SIM card.
The workflow that system of the present invention carries out call switching has following steps：
（1）, calling number Inbound Calls；
（2）, the first radio-frequency module telephone number is notified into single-chip microcomputer；
（3）, single-chip microcomputer control the second radio-frequency module calling intercom number；
（4）, the second radio-frequency module calling intercom number；
（5）, internal number connect, the second radio-frequency module notice single-chip microcomputer has been turned on；
（6）, single-chip microcomputer calling number is sent to FPGA；
（7）, FPGA calling number is sent to the second radio-frequency module；
（8）, FPGA notice single-chip microcomputer number be sent completely；
（9）, single-chip microcomputer control the first radio-frequency module connect phone；
（10）, the first radio-frequency module voice signal is connected to FPGA；
（11）, FPGA speech data is sent to the second radio-frequency module；
So far, calling party connects voice with callee's can, converse.
Compared to existing equipment, the present invention has advantages below：
1st, small volume, it is convenient for carrying；
2nd, built-in portable power source power supply, charging are convenient；
3rd, China Mobile, UNICOM, telecommunications GSM/WCDMA/LTE the whole networks is supported to lead to；
4th, antenna gain is high, and laser propagation effect is good.
Operation principle of the present invention：During outside the first radio-frequency module of number call, FPGA is by the PCM signal of the first radio-frequency module
It is connected to the second radio-frequency module, single-chip microcomputer（STM32）The second radio-frequency module is controlled to call intercom number, so as to realize to internal number
Protect and hide.Outside can not perceive direct correspondence between outside number and intercom number, can only perceive outside
Communication number between the first radio-frequency module.And device end be able to can also be prevented with internal number geographically apart from far
The only monitored control of Content of Communication.It can realize that calling number is only dialled to the first radio-frequency module by setting different inside number
Can of making a phone call and different inside signal communications.
