Next, in the step s 120, such as successful match, then the SIM card information based on successful match, which is read, receives channel
User information and start monitoring to the corresponding user terminal of the user information.
Specifically, SIM card information includes: the commander where SIM card mark, the corresponding user terminal ID of SIM card, SIM card
Terminal and the user terminal relationship of its subordinate and corresponding encryption and decryption secret keys.Wherein, SIM card mark for different SIM cards into
Row is distinguished；The corresponding user terminal ID of SIM card is used to indicate the SIM card for handling the data of which user terminal；Commander is eventually
The user terminal relationship of end and its subordinate are used to control which user of its subordinate for the command terminal where indicating the SIM card
Terminal；Command terminal encryption and decryption secret keys corresponding with the user terminal of its subordinate are corresponding with each user terminal respectively, and different
User terminal encryption and decryption secret keys it is different, a command terminal thus may be implemented and handle multiple user terminals.
When specific implementation, the corresponding user terminal ID of the SIM card can determine the user terminal that the SIM card is handled,
Only when receiving the user terminal of the received ID of channel, which just works.After SIM card successful match, it can get
Its unique SIM card mark, it is possible thereby to determine the SIM card for uniquely corresponding to the user terminal of the reception channel.Command terminal with
The user terminal relationship of its subordinate designates command terminal can be with the range of subordinate's user terminal of monitoring management.Command terminal with
The corresponding encryption and decryption secret keys of the user terminal of its subordinate indicate there is different encryptions between different user terminal and command terminal
And decruption key, to realize the secure communication of command terminal Yu each subordinate's user terminal.It is whole when obtaining multiple users simultaneously
When holding corresponding channel information, signal-processing board can carry out parallel processing to the channel information of multiple user terminals, can keep away
The limitation for exempting from individual commander's card service frequency, causes to command continuity poor.
Corresponding diagram 3 carries out self-test to SIM card information, judges whether it is again after ready after command terminal initialization
Commander's machine in concentrating type command jurisdiction belongs to commander's machine of this cluster management in this way, then is read by the reception channel
User information, thereafter, starting channels track capture carries out this communication for command, completes this command function.
The present invention is designed using concentrating type command terminal, is needed multiple SIM card integrated management, effectively room for promotion is sharp
With rate, so that hardware cost does not increase, and unit time volume of transmitted data is multiplied.Pacified simultaneously using individual circuit board
SIM card is filled, commands clamping to take during convenient to use.When in use, according to transmission demand, select suitable communication frequency complete
At the transmission of file or image data.It is resolved using large resource FPGA and DSP, effectively increases command type user's concentrating type
Management, improves the service applications frequency such as positioning, communication.
The present invention passes through the data of the multiple communication channels of multiple SIM card parallel processing, breaks through the commander for using a SIM card
Limitation of the terminal to subordinate's general subscriber terminal quantity, and can supervise in real time receive all subordinate's general subscriber terminals on notify
Breath.Meanwhile after the present invention can also divide larger data, is distributed by different SIM cards to subordinate's general subscriber terminal and is transmitted,
To realize large capacity concentrating type command and management.By the software control to signal-processing board and SIM card plate, may be implemented to point
Piece user terminal data reception delay is controllable, and to fragment data serial number, is easy to data recombination to have, to realize great Rong
The method for measuring concentrating type command terminal command and management.
While it is disclosed that embodiment content as above but described only to facilitate understanding the present invention and adopting
Embodiment is not intended to limit the invention.Any those skilled in the art to which this invention pertains are not departing from this
Under the premise of the disclosed spirit and scope of invention, any modification and change can be made in the implementing form and in details,
