Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The utility model discloses as shown in fig. 1, be a section take a ray of logical aerial, big dipper transceiver module, ARM treater, voice compression module, attack and put module, bluetooth module, net gape module, 422 communication module, 232 communication module, USB communication module, control panel, power module, external conversation handle, reserve the communication terminal of earphone and speaker interface.

The voice compression module comprises microphone voice acquisition and loudspeaker voice output, the low level of the module enable pin is effective, data is transmitted by a serial port with a 9600 baud rate, the data is directly exchanged with an ARM processor in a 16-system form, a header and a tail are specified, and the data can be output only when the data is complete. Voice data can be stored for up to 60 seconds at a time, on the order of milliseconds of compression and decompression speed. The processor receives the data sent by the voice module, performs packet cutting by using 76 bytes, performs packet sending and marks packet numbers. In order to ensure that the voice input end is purer, an analog signal input filter circuit is added, and a common-mode inductor is added at the front power supply section of the voice module.

The Beidou transceiver module RNSS short message communication and the RDSS positioning acquisition are respectively transmitted with the ARM processor through serial ports. Due to the limitation of a baseband, short messages can be transmitted once in 1.5 seconds of experimental data, and the interface area identifies the interface of the Beidou card and provides a power supply interface of a wire-through antenna.

The Beidou card module consists of a plurality of double card slots and two multiplexers, and multi-card sending is realized by switching data pins through the multiplexers, wherein each card is sent for 1.5 seconds.

The conversation handle integrates speaking, sending, a loudspeaker and a microphone, a speaking key is synchronous with a speaking key of the control panel, and the built-in microphone is cut off when the speaking key of the handle is pressed. In order to avoid the interference of a digital circuit to an analog circuit, the keys and the processor are directly transmitted in a photoelectric coupling mode.
