Optical modem device capable of encrypting earthquake early warning information

The invention discloses an optical modem device with an earthquake early warning information encryption function, which comprises a radio frequency receiving module, a baseband processing module, an information encryption module and a radio frequency emission output module, carries out encryption processing on all earthquake early warning information on the basis of a traditional optical modem, ensures that the released early warning information is safe and reliable, and improves the safety of the earthquake early warning information. When earthquake early warning information is received, the radio frequency receiving module forwards the collected information to the baseband processing module, and the baseband processing module and the information encryption module encrypt the received information and forwards the encrypted information to the radio frequency output module. The optical modem has the advantages of rich functions, safety, reliability, energy conservation, high user experience and the like, and h
