When the utility model and simplex radio station were used in conjunction, simplex radio station was drawn respectively six roots of sensation wiring and is connected with 6 interfaces of the present utility model. Drawing wiring by radio station power supply E is connected with interface ［ 6 ］, the SQ signal output part in radio station is drawn wiring and is connected with interface ［ 7 ］, the ptt switch lead-out wire in radio station is connected with jack ［ 8 ］, the loudspeaker in radio station is connected with interface ［ 9 ］, the microphone in radio station is connected with interface ［ 10 ］, and the ground wire in radio station is connected with interface ［ 11 ］.

It is as follows that simplex radio station and the utility model connect the machine course of work: when the radio station received communication signal, the level that is input to recording circuits for triggering ［ 12 ］ by interface ［ 7 ］ was in high level, and this high level is through Y ₁, Y ₂Two utmost point NAND gate shapings are again through C ₁, R ₁The differential electricity forms the positive pulse of pulsewidth greater than 20ms, makes BG ₁Conducting, pulse signal output to 32 pin of chip ［ 3 ］, make chip ［ 3 ］ be operated in the recording playback state, simultaneously, and through NAND gate Y ₁, Y ₂High level after the shaping is sent into chip ［ 3 ］ through 39 pin of chip ［ 3 ］ again, makes chip be in recording state; End when communication signal, then SQ becomes low level by high level, and this low level is through NAND gate Y ₁, Y ₂The back is to BG ₁Work is influence not, but through Y ₁, Y ₃, Y ₄, C ₂, R ₂, BG ₁, still obtain the positive pulse of pulsewidth at 32 pin of chip greater than 20ms, make chip ［ 3 ］ still be operated in the recording playback state, what obtained at chip ［ 3 ］ 39 pin this moment then is low level, makes chip ［ 3 ］ be in tone playing state.Meanwhile, 41 pin of chip ［ 3 ］ obtain a negative pulse, this pulsed drive triode BG ₄Conducting makes BG ₂Base stage be high level, BG ₂Saturation conduction, PTT interface ［ 8 ］ ground connection makes the radio station be in emission state.D ₄Be clamping diode, its effect is when SQ is high level, makes BG ₂The base stage pincers fixes on low level, BG ₂Reliably end, the radio station is in accepting state all the time.When transferring playback to, by resistance R ₃, capacitor C ₆The delay circuit of forming, recording is finished do not change tone playing state at once over to, but wait about 1～2 second, its main effect has two: the one, and the radio station is transferred to this process of emission from reception can a stable time, the 2nd, before time-delay is intact if signal is received in the radio station again, then this machine enters recording state again, and this machine delay time generally fixed on about 1～2 second.

In above-mentioned recording playback transfer process, during recording, the audio signal of radio station loud speaker is given 14 pin of chip ［ 3 ］ through the capacitance-resistance matching network through interface ［ 9 ］, this signal deposits in after the A/D conversion process in the D41256 memory chip ［ 4 ］, and during playback, chip ［ 3 ］ is sense information from chip ［ 4 ］, and convert analog signal to through D/A and export from 19 pin, be sent to the microphone in radio station through matching network, like this, finish the audio frequency coupling conversion in the whole recording playback process.

When the SQ signal from the radio station input, via controller ［ 5 ］ is sent into chip ［ 3 ］, ［ 4 ］, if the signal time of typing surpasses the waiting time of setting, then works by the full automatic reset circuit ［ 18 ］ of record.When the chip record is full, send into a high level by 6 pin of chip ［ 3 ］ and give circuit ［ 18 ］, make triode BG ₃Conducting, the relay J energising, normally opened contact K adhesive makes 25 pin RZSZTO of chip ［ 3 ］ hold ground connection, and chip ［ 3 ］, ［ 4 ］ are automatically reset, and is in the address initial position, changes the wait tone playing state over to.

When communication ends, the SQ signal then stops recording circuit ［ 12 ］ automatically and works, its NAND gate Y during by high step-down ₁Output level will uprise by low because capacitor C ₃The current potential at two ends can not suddenly change, and this high level is delivered to triode BG ₅Base stage, make BG ₅Saturation conduction BG ₅Emitter produce positive arteries and veins and produce to dash and send into through 33 pin of chip ［ 3 ］, make chip ［ 3 ］ stop recording operation automatically.Because playback is BG at the end ₅Base stage can not get high level, BG ₅Do not work, then stop recording circuit ［ 12 ］ this moment is not automatically had influence to playback work.

Like this, just can finish communication signal automatically by simplex station and the utility model logotype and receive the forwarding work of emission.

The utility model has the advantages that simple in structure, compact, cost is low, be easy to make, convenient with the simplex station logotype, can save the radio station manpower, get high communication efficiency and quality, help realizing the communication automation, also expanded the communication distance of unit simultaneously, for the wireless tranceiver mobile communication particularly suitable in public security, traffic and other places to unit.

Specific embodiment of the utility model is shell ［ 1 ］ is made 45 * 120 * 100mm by aluminium alloy the flat box of hexahedron rectangle, its 6 interfaces ［ 6 ］ ［ 7 ］ ［ 8 ］ ［ 9 ］ ［ 10 ］ ［ 11 ］ are contained in case surface, 6 interfaces adopt jack, movement ［ 2 ］ is a printed circuit board (PCB), last dress T6668 language processor chip ［ 3 ］, D41256 storage of processor chip ［ 4 ］, controller ［ 5 ］, 7 circuit ［ 12 ］ ［ 13 ］ ［ 14 ］ ［ 15 ］ ［ 16 ］ ［ 17 ］ ［ 18 ］ of controller ［ 5 ］ are by resistance, di-cap, triode R NAND gate integrated circuit connects to form by aforementioned.
