Description

Shortwave intelligence voicedata terminal

Technical field

The utility model belongs to the HF Wireless Communication technical field, especially relates to a kind of shortwave intelligence voicedata terminal.

Background technology

At present, the radio station has been widely used in every field such as public security, fire-fighting, hotel, market and restaurant as a kind of comparatively ripe half-duplex voice communications systems.At present, the modulator-demodulator of employed externally positioned type does not generally possess the ability of digital voice and secure communication on the market, and the transfer of data effect is relatively poor, thereby be the communication requirement that adapts to the present stage fast development, and need carry out corresponding improvement to the existing employed modulator-demodulator of short-wave radio set.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of shortwave intelligence voicedata terminal is provided, its reasonable in design, intelligent degree height, perfect in shape and function and communication performance excellence, possess simulated voice and digital voice communication function, can effectively solve defective and deficiencies such as existing ability that does not possess digital voice and secure communication of existing externally positioned type modulator-demodulator and transfer of data effect be relatively poor.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of shortwave intelligence voicedata terminal, it is characterized in that: the modulation module that comprises in the signal transmitting and receiving link that is serially connected in short wave radio station and join with the signal transceiver of described short wave radio station, described modulation module comprises by primary processor and the double-core signal processing unit formed with the coprocessor that primary processor joins, the FPGA field programmable gate array module of joining with primary processor and the A/D modular converter and the D/A modular converter that join with primary processor respectively, described A/D modular converter and D/A modular converter all join with signal transceiver.

Described primary processor is the inner DSP digital signal processor that is integrated with rate adaptation processing module and signal equalization processing module, and described coprocessor is the inner DSP digital signal processor that is integrated with the digital speech coding/decoding module.

Also comprise the externally positioned type security module that joins with FPGA field programmable gate array module.

The utility model compared with prior art has the following advantages:

1, can expand and upgradability strong, the two DSP structures of entire equipment hardware using FPGA+, can be under the condition of not opening equipment online function of injecting software program, thereby can realize on-line loaded and upgrading, for the user has reduced later maintenance and upgrading expense.

2, have multi-service tenability and professional automatic tracking capability, the utility model decapacitation is supported outside the data communication, adopts the advanced person's of external import digital sound sign indicating number chip to realize the digital speech codec functions; It is professional from motion tracking to adopt synchronous bootstrap technique and modulating characteristic recognition technology to realize simultaneously, has simplified the complexity when using greatly.Thereby, the utlity model has the ability of debit from motion tracking originating party business, have certain intelligent.

3, has the rate adaptation function, can select transmission rate automatically according to channel quality, specifically be to adopt high-speed data chain HDL technology to realize the rate adaptation function, and the high-speed data chain HDL technology that is adopted adopts two-way several transmission method, can in acknowledgement frame, add local data, improved message capacity, high-speed data chain HDL adopts the convolutional encoding disassemble technique to realize the automatic coupling of transmission rate simultaneously, and real-time is good.In the actual use, when the short wave channel condition is bad, can guarantee the correct transmission of data, after channel condition improves, can automatically restore to high-speed transfer, need not human intervention, improve serviceability and reliability.

4, data communication feature excellence adopts convolution soft-decision and up-to-date short wave channel balance module to improve data communication feature, and like product is compared in actual measurement at present can reduce by 3～4dB to the channel quality requirement.

5, adopt the externally positioned type security module, can be for convenience detach, this security module adopts the non-linearity complicated algorithm simultaneously, and encryption strength is very high.

6, except that supporting data service, can also carry out simulated voice and communicate by letter with digital voice.

In sum, the utility model degree height reasonable in design, intelligent, perfect in shape and function and communication performance excellence, possess simulated voice and digital voice communication function, can effectively solve number of drawbacks and deficiencies such as existing ability that does not possess digital voice and secure communication of existing externally positioned type modulator-demodulator and transfer of data effect be relatively poor.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.
