High-speed train operation natural environment monitoring device based on ZigBee

The invention discloses a high-speed train operation natural environment monitoring device based on ZigBee. The device comprises a ZigBee terminal, a ZigBee coordinator, a data transmission module, ascheduling management module and an intelligent decision-making module, the RF module is wirelessly connected with a ZigBee terminal; the signal amplification module comprises a single-chip microcomputer, a voltage input module, a signal controllable amplifier, a voltage output module, an AD conversion module and a DA conversion module, the single-chip microcomputer is connected with the DA conversion module, and the input end of the signal controllable amplifier is connected with the voltage input module. In the voltage signal amplification part, the voltage signal is amplified by using a method of setting gain by software, so that the traditional mode of manually adjusting an amplification gear is changed; an intelligent decision-making unit is additionally arranged on an existing natural disaster monitoring dev
