Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
A kind of radio station Voice over Internet equipment as shown in Figure 1, comprise processor module, speech processing module, encoding and decoding speech module, voice driven module, FPGA(field programmable gate array) module, PTT(PTT) driver module, take detection module, described processor module is respectively by SPI(Serial Peripheral Interface (SPI)) connect at least two encoding and decoding speech modules, by HOSRPORT(host port) interface connection speech processing module, FPGA module is connected by address data bus, this FPGA module comprises the FPGA that model is XC3S50AN-4TQG144I, described speech processing module, encoding and decoding speech module connects with FPGA module respectively by 2MTDMHW bus, this encoding and decoding speech module and voice driven module are at least two, encoding and decoding speech module comprises the CODEC(coder that model is LE58QL021FJC), and a voice driven module is connected with an audio coder & decoder (codec) by four line analog voice interfaces, this voice driven module connects with radio station, described PTT driver module, the quantity taking detection module and voice driven module is identical and connect with FPGA module.Device handler module completes the initial work of encoding and decoding speech module and speech processing module, and the result detected according to voice activation activates or closes PTT, and monitoring radio station takies situation; Speech processing module is responsible for voice activation detection, Echo Cancellation; Encoding and decoding speech module completes the conversion of digital speech and analog voice, realizes the codec functions of voice; Voice driven module completes I/O amplification and the impedance matching of voice signal; FPGA module completes the adjustment of 2MTDMHW bus slots, drives PTT module, detects Seize ACK message; PTT module completes PTT signal type and arranges, and PTT signal exports; Take detection module and complete the detection that radio station takies index signal, and send FPGA by testing result.
In technique scheme, the EPROM(EPROM (Erasable Programmable Read Only Memory) that the FLASH that described processor module comprises processor that model is MPC8270CZUQLDA, model is JS28F128J3D-75, model are SST39VF040-70-4I-NHE) and model be the SDRAM(synchronous DRAM of MT48LC16M16A2P-75IT).
In technique scheme, described voice driven module comprises the amplifier that model is MC33272AD, the universal toggle switch adjusting impedance and Gain tuning potentiometer.Different radio station have different speech level and interface impedance, this equipment voice driven module carries out I/O amplification and the impedance matching of voice signal, I/O amplifying circuit forms duplicate supply anti-phase input formula ac amplifier circuit by amplifier MC33272AD, amplifying circuit feedback resistance adopts potentiometer, Circuit tuning gain, radio interface presets different interface impedances, employing toggle switch is selected, after connecting radio station, interface index according to radio station adjusts electric-level gain and the interface impedance of this equipment, guarantees suitable signal level.
In technique scheme, it is the relay of AGQ200A03 and the universal toggle switch arranging PTT type that described PTT driver module comprises model.PTT has current mode and voltage-type two kinds, and this equipment PTT module adopts dpdt relay AGQ200A03 to export PTT signal.One side tool of AGQ200A03 is designed to current mode, and another side tool is designed to voltage-type.Employing toggle switch is selected.
In technique scheme, described in take detection module and comprise optocoupler 4N25 and rc integrating circuit.Hurry with signal designation radio station, this signal is input to equipment by radio station, and Seize ACK message is also divided into current mode and voltage-type, and this hold facility detection module adopts optocoupler 4N25 to detect current mode signal, and rc integrating circuit detects voltage mode signals, adopts toggle switch to select.
Radio station voice are admitted to this InterWorking Equipment, first enter voice driven module, adjust to suitable level, and suitable signal level is that reliable operation is necessary.The voice signal adjusted enters encoding and decoding speech module, is converted into the PCM digital signal of 64Kbit, and is loaded in a time slot of 2MTDMHW.This 2MTDMHW adjusts after frame head and time slot through FPGA and delivers to speech processing module, and here voice complete voice activation detection, Echo Cancellation.Speech processing module, by interrupting report processor module when voice being detected.Processor module receives in this and has no progeny, and carries out PTT process, drives PTT interface by FPGA, generates PTT signal.The detection module that takies of equipment detects radio station busy condition, when discovery radio station busy, and the PTT in this radio station of not deexcitation.The voice that speech processing module is disposed are loaded into again in 2MTDMHW bus, send back to encoding and decoding speech module through FPGA.64Kbit digital signal is reduced into analog voice signal by encoding and decoding speech module, then through voice driven module, complete voice and amplify, deliver to another radio station, voice complete the relay from a radio station to another radio station, since then.
The signal that radio station likely receives when being in accepting state is stronger noise signal, if can not carry out voice activation detection preferably, missing Noise Identification is voice signal, will make PTT signal Chang Youxiao, and cannot carry out voice relay.The speech processing module of this equipment adopts special chip AC490-CBL-I to carry out voice activation detection, the different qualities of voice activation detection algorithm Main Basis voice and noise carries out the judgement of voice and noise, speech signal segments and noise signal section can be detected from the digital signal that continuous sampling obtains, its accurately speech terminals detection improve system recognition rate and treatment effeciency.
