1. Equipment introduction:
The wireless warning broadcast host integrates remote text warning, telephone warning, SMS warning, local microphone and USB insertion functions. It adopts advanced GPRS communication module internally and supports mobile and Unicom network standards (4G network optional) to maintain data communication with the server. The platform software can remotely monitor the online and offline status of the terminal. At the same time, the internal integration of 100W digital function (200W optional) can simultaneously connect 4 groups of speakers to operate at full power, with low standby power consumption.
When geological disasters such as flash floods occur, the terminal can be remotely awakened through channels such as telephone, SMS, GPRS wireless, etc., and warning messages can be sent to the affected area of the geological disaster, and on-site command can be carried out to achieve personnel evacuation and material transfer. This device plays a crucial role in geological disaster warning, flash flood warning, forest fire prevention, flood prevention and disaster prevention.
