Description
Technical field
The utility model relates to a kind of wireless image communication system, particularly relates to a kind ofly can receive multiway images and be convenient to the wireless image base stations in trunking communication system of network operation.
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 base station is the central management platform based on image transmission/reception.Although current wireless image communication system base station has image transmission function, it is comparatively single that it receives image simultaneously, and be not easy to carry out the operation such as image viewing, data modification by network, limits the range of application of wireless image communication.
Utility model content
The purpose of this utility model is just to provide to solve the problem a kind of and can receives multiway images and be convenient to the wireless image base stations in trunking communication system of network operation.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of wireless image base stations in trunking communication system, comprises band pass filter, two-way amplifirer, low noise amplifier, baseband module, switch, GPS Rcv decoder, serial server, encoding board, decoding deck, control board, keyboard, LCD and network interface, the communication terminal of described band pass filter is connected with antenna, the data transmission terminal of described band pass filter is connected with first input/output terminal of described two-way amplifirer, the output signal end of second input/output terminal of described two-way amplifirer is connected with described baseband module by described low noise amplifier, the input signal end of second input/output terminal of described two-way amplifirer is connected with described baseband module, described baseband module also with described switch, described GPS Rcv decoder, described serial server is connected with described control board correspondence, and described GPS Rcv decoder exports four road gps datas, and 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, four described decoding decks are connected with network interface correspondence, described encoding board input audio/video information or output voice messaging, each described decoding deck output sound video information or input voice information.
The beneficial effects of the utility model are:
Wireless image base stations in trunking communication system described in the utility model can receive the four up SD images in tunnel simultaneously, namely receives the image information that four terminals send; Descending also can transmission of one line SD GIF image, send in a broadcast manner, four terminal equipments all can receive, and realize the transmitted in both directions of image, and voice are also bidirectional real-times.When communication link is unimpeded, the software real time modifying parameter can held by PC, simple and efficient to handle.
Accompanying drawing explanation
Fig. 1 is the system block diagram of wireless image base stations in trunking communication system 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 base stations in trunking communication system described in the utility model comprises band pass filter, two-way amplifirer, low noise amplifier, baseband module, switch, GPS Rcv decoder, serial server, encoding board, decoding deck, control board, keyboard, LCD and network interface, the communication terminal of band pass filter is connected with antenna, the data transmission terminal of band pass filter is connected with first input/output terminal of two-way amplifirer, the output signal end of second input/output terminal of two-way amplifirer is connected with baseband module by low noise amplifier, the input signal end of second input/output terminal of two-way amplifirer is connected with baseband module, baseband module also with switch, GPS Rcv decoder, serial server and control board correspondence is connected, and GPS Rcv decoder exports four road gps datas, and keyboard and LCD are connected with the input of described control board respectively, switch also respectively with serial server, encoding board, four decoding decks are connected with network interface correspondence, encoding board input audio/video information or output voice messaging, each decoding deck output sound video information or input voice information.
This base station is the bi-directional communication device of time-division slot transmitting and receiving, and antenna is used for receiving and transmitting.Band pass filter is used for the clutter beyond filtering working frequency points, makes the signal of transmitting and receiving cleaner.Two-way amplifirer is the effect playing power amplification when transmitting, and when receiving is a straight-through signal path, and the reception of power amplifier controls by baseband module with launching.Low noise amplifier is that the signal received is amplified fixing multiple, so that rear class process.Baseband module is then convert the radiofrequency signal received to network data to output to switch, or becomes radiofrequency signal to output to two-way amplifirer the data transaction that network inputs.Switch is then network data exchange, decoding deck, encoding board, baseband module, serial server all connect and are connected with it, also can external server, PC or other local area network (LAN)s, checked by network, revise the video image that device parameter and viewing receive.Decoding deck is that the Data Analysis of the corresponding IP address received by baseband module becomes vision signal to export, four tunnel vision signals of can decoding at most; Decoding deck there is speech coding function, sending giving baseband module after speech coding.Encoding board is then network data audio-video signal being compressed into corresponding IP address, is sent by baseband module; Encoding board has tone decoding module, the speech data of the corresponding IP that baseband module can be received resolves rear output.GPS Rcv decoder is that the gps data analyzing and processing after the terminal received by baseband module increases numbering becomes the gps signal of standard to export, and GPS Rcv decoder has four tunnels to export, i.e. corresponding four terminal equipments.Serial server converts the order of reading, revising baseband module parameter in network to RS232 data to give baseband module, and the reply data after being received orders by baseband module converts network data to and gives operator, achieves the Long-distance Control of equipment.
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 without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
