Description
Technical field
The utility model relates to a kind of wireless image communication system individual soldier terminal, relates in particular to the remote-operated wireless image trunked communication system individual soldier terminal of a kind of energy.
Background technology
Along with the continuous progress of science and technology, the field application such as the emergency communication of wireless image transmission in the industries such as public security, fire-fighting, electric power, traffic, oil field, mineral products, broadcasting and TV are very extensive, and wireless image communication system individual soldier terminal is the terminal equipment that carries out image transmitting with wireless image communication system base station.
The necessary manual amendment of parameter of traditional wireless image communication system individual soldier terminal, with working after base station parameter coupling, this is not easily in actual applications, cannot meet the parameter of user in base station energy remotely modifying individual soldier terminal, and can see the requirement of current individual soldier's positional information.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of energy remote-operated wireless image trunked communication system individual soldier terminal.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of wireless image trunked communication system individual soldier terminal, comprise band pass filter, two-way amplifirer, baseband module, switch, GPS receiver module, serial server, encoding board, control board, keyboard, LCD and network interface, the communication terminal of described band pass filter is connected with radio-frequency antenna, the data transmission terminal of described band pass filter is connected with described baseband module by described two-way amplifirer, described baseband module also with described switch, described GPS receiver module, described serial server is connected with described control board is corresponding, described GPS receiver module is connected and is used for inputting gps data with gps antenna, described keyboard is connected with the input of described control board respectively with described LCD, described switch also respectively with described serial server, described encoding board is connected with described network interface is corresponding, described encoding board input audio/video information or output voice messaging.
The beneficial effects of the utility model are:
Wireless image trunked communication system individual soldier terminal described in the utility model can uplink audio-video signal, descending received speech signal, GPS receiver module adds GPS locating information recompile after self numbering, then send by baseband module data channel, after base station receives, decoding just can obtain current numbering individual soldier's positional information.In the situation that wireless link, cable network link are unimpeded, amendment individual soldier interrupt parameters can long-rangely be read in base station, easy to use succinct.
Brief description of the drawings
Fig. 1 is the system block diagram of wireless image trunked communication system individual soldier terminal described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, wireless image trunked communication system individual soldier terminal described in the utility model comprises band pass filter, two-way amplifirer, baseband module, switch, GPS receiver module, serial server, encoding board, control board, keyboard, LCD and network interface, the communication terminal of band pass filter is connected with radio-frequency antenna, the data transmission terminal of band pass filter is connected with baseband module by two-way amplifirer, baseband module also with switch, GPS receiver module, serial server is connected with control board is corresponding, GPS receiver module is connected and is used for inputting gps data with gps antenna, keyboard is connected with the input of control board respectively with LCD, switch also respectively with serial server, encoding board is connected with network interface is corresponding, encoding board input audio/video information or output voice messaging.
Radio-frequency antenna in this individual soldier terminal is for receiving and emitting radio frequency signal, and gps antenna is to receive gps satellite signal; Band pass filter is the clutter beyond filtering working frequency points, makes the signal that transmits and receives cleaner; Two-way amplifirer is the effect of playing power amplification in the time transmitting, and is a straight-through signal path in the time receiving, and the reception of two-way amplifirer and transmitting are subject to baseband module control; Baseband module is to convert the radiofrequency signal receiving to network data to output to switch, or becomes radiofrequency signal to output to two-way amplifirer the data transaction of network input; Switch is for network data exchange, and encoding board, baseband module, serial server are all connected with it; Encoding board is the network data that audio-video signal is compressed into corresponding IP address, is sent by baseband module, has tone decoding module on encoding board, and the speech data of the corresponding IP that baseband module can be received is exported after resolving; GPS receiver module is that the numbering of self is added on and in positional information bag, after recompile, gives baseband module transmitting; Serial server is to convert the order of reading, revise baseband module parameter in wireless network to RS232 data to give baseband module, reply data after baseband module is received orders converts network data to and goes out by radio-frequency transmissions, has realized the Long-distance Control of equipment.The state information of LCD display device, can revise parameter by keyboard operation, in the situation that wireless network is obstructed, just must revise parameter with keyboard operation, ensures unanimously with the parameter of base station, could normally work.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as the technical scheme that can realize on the basis of above-described embodiment without creative work, all should be considered as falling within the scope of the rights protection of the utility model patent.
