Fig. 1 illustrates the schematic diagram that possesses the communication system of positioning function wireless interspeaker operation according to of the present utility model;
Fig. 2 is the schematic diagram that the electronic geographic-information system on the main frame that positional information with wireless interspeaker is presented at command centre is shown;
Fig. 3 is the structured flowchart that illustrates according to the wireless interspeaker of the GPS of comprising chip of the present utility model.
Embodiment
Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.
The locator for its position, location is equipped with under the prerequisite that does not influence existing intercom communication function,, as global positioning system (GPS) chip in the wireless interspeaker of the present utility model.
According to wireless interspeaker of the present utility model, when receiving the order that the user finishes to converse, the positional information modulation that locator is received becomes and can send and receive the analog signal (to call first analog signal in the following text) that the frequency of signal sends at described wireless interspeaker, and sends first analog signal after the modulation by communication unit to command centre.
Fig. 1 is the schematic diagram that illustrates according to the communication system of wireless interspeaker operation of the present utility model.
With reference to Fig. 1, in according to communication system of the present utility model, when comprising that the wireless interspeaker with GPS chip sends audio digital signals or call voice signal, the modulator/demodulator demodulation of command centre's communication radio station recovers locator data information wherein, be transferred to the main frame that links to each other with communication station, after data processor in main frame is handled positional information is recorded in the database of main frame of command centre, and is presented in real time on the user interface of the computer (PC) that is connected with main frame.
Fig. 2 is the schematic diagram that the electronic geographic-information system on the main frame that positional information with wireless interspeaker is presented at command centre is shown.
Particularly, positional information also comprises wireless interspeaker user's longitude and latitude information, thereby these information and electronic geographic-information system can be mated, and shows the current position of this intercom at electronic chart.With reference to Fig. 2 as can be known, command centre can monitor the position with all intercoms of center communication in real time.
Fig. 3 is the structured flowchart that illustrates according to wireless interspeaker of the present utility model.
With reference to Fig. 3, wireless interspeaker of the present utility model comprises communicator 3 10, modulator/demodulator 320, I/O (I/O) unit 330 and locator 340.In addition, wireless interspeaker also comprises PTT(Push To Talk)) key, when the PTT key was pressed, 330 sent the initiation calling order to the I/O unit; And when the PTT key was released, 330 sent the order that finishes conversation to the I/O unit.
I/O unit 330 receives the order that is used for initiating conversation and end conversation from the PTT key.When I/O unit 330 receives the order of initiating conversation, the simulation call voice that I/O unit 330 receives from the user, and this simulation call voice sent to modulator/demodulator 320; And when I/O unit 330 receives the order that the user finishes to converse, I/O unit 330 will represent that the call ending signal of end of conversation order is sent to locator 340.
Locator 340 receives the positional information from the wireless interspeaker of gps satellite, and when receiving described call ending signal, and the positional information of wireless interspeaker is sent to modulator-demodulator 320.
Modulator/demodulator 320 is modulated first analog signal that becomes pre-configured frequency with the positional information that receives, and this second analog signal is sent to communication unit 310.
In addition, when wireless interspeaker received information, modulator/demodulator 320 also can generate analog signal amplification, filtering, mixing and the frequency discrimination from communication unit 3 10 the simulation call voice, and should simulate call voice and export to the user.
In wireless interspeaker, to become the analog signal of pre-configured frequency from user's the amplification of simulation conversation signal, filtering, modulation, perhaps will generate the simulation call voice from analog signal amplification, filtering, mixing and the frequency discrimination of other wireless interspeakers, these all are prior aries, therefore do not repeat them here.
At this, need to prove that the communication radio station of command centre's main frame is the identical locating module of being and not being line intercom and processing module also.For example, when the communication unit on the main frame of command centre received analog signal, its modulator/demodulator can demodulation positional information wherein, and is presented in the electronic geographic-information system.With other analog signal amplify, filtering, mixing and frequency discrimination generate the simulation call voice, and export to the commanding officer of command centre.Therefore, main frame can be understood as and receive and transmitting power is bigger, with better function is positioned at command centre's wireless interspeaker.
Although, in the present embodiment when the conversation that finishes from the user (when the PTT key is released), send the positional information of this wireless interspeaker to command centre, but according to actual needs, the communication radio station of wireless interspeaker and command centre or other wireless interspeaker can carry out speech communication at any time.
When communication unit 310 sends relevant positional information, I/O unit 330 will receive simulates call voice from the user and sends to modulator/demodulator 320, this moment, modulator/demodulator 320 was with the received amplification of simulation call voice, filtering, be modulated to analog signal, and send the analog signal of described modulation by communication unit 420.
Communication is two-way carrying out.Therefore when communication unit 310 receives analog communication signal from other intercoms, send it to modulator/demodulator 320, then modulator/demodulator 320 generates the simulation call voice with the amplification of analog communication signal, filtering, mixing and the frequency discrimination of communication unit 310 receptions, and be sent to I/O unit 330, exported to the user thereby should simulate call voice by I/O unit 330.
Although represent with reference to preferred embodiment and described the utility model, it should be appreciated by those skilled in the art that under the situation that does not break away from the spirit and scope of the present utility model that are defined by the claims, can carry out various modifications and conversion to these embodiment.
