Communication early-warning machine

Abstract

The invention relates to a communication early-warning machine which solves technical problems that existing communication early-warning machines are large in size, high in power consumption, low in integration level and incapable of setting warning priorities. The machine comprises a master control unit, a power module, a key processing unit, a GPRS / GSM (general packet radio service / global system for mobile communications) module, an audio mixing unit, a speech synthesis unit, an interphone module, a microphone processing unit, a recording and playback unit, a power amplification module and a frequency modulation transmission station, wherein the master control unit is provided with an SPI (serial peripheral interface), and the GPRS / GSM module, the speech synthesis unit and the recording and playback unit are connected with the SPI respectively; the audio mixing unit is connected with the GPRS / GSM module; the speech synthesis unit, the interphone module and the microphone processing unit are arranged between the audio mixing unit and the master control unit respectively; the recording and playback unit, the power amplification module and the frequency modulation transmission station are connected with the audio mixing unit respectively; the speech synthesis unit comprises an XFS4041A chip and an XFS4041B chip. The machine is widely applied to prevention and treatment engineering of water conservancy, meteorology, geological disasters and the like.

Description

Technical field [0001] The invention relates to an early warning device, in particular to a communication early warning machine. Background technique [0002] As we all know, in the field of prevention and control of water conservancy, meteorology, and geological disasters, communication early warning aircraft collect and analyze data in advance and send out warning signals, so that people can be informed of potential disasters in advance, so that people can take corresponding preventive measures to avoid personal damage. Property was damaged. [0003] However, the existing communication early warning machine has the defects of large size, high power consumption, low integration, and inability to set the alarm priority. Summary of the invention [0004] In order to solve the technical problems of large volume, high power consumption, low integration, and inability to set alarm priority of the existing communication early warning machine, the present invention provides a small volum...
