The invention discloses a
train broadcasting system facilitating positioning and navigation. The
system comprises a processor, a capacitive touch screen, a control key, a WIFI module, a
Bluetooth module, a
microphone sound card and an SD card module. The
system further comprises an emergency power supply module, a monitoring module, a circuit self-checking module and a navigation module. The navigation module comprises a
base station positioning module, a GPS and Beidou dual-navigation module and an inertial navigation module; and the processor comprises a
broadcasting module. According to thesystem, the labor intensity of
train broadcasters is reduced, the working efficiency is improved, the quality of services is improved,
operating cost is reduced, and normal
broadcasting and playing of videos and audios can be facilitated; moreover, the system can navigate and position a
train, has higher-reliability positioning performance through GPS and Beidou comprehensive positioning, and canperform normal positioning through inertial navigation and
base station positioning module assisted navigation when signals are insufficient and no
signal exists, so the navigation accuracy and stability of the system are improved, and the system is suitable for popularization and application.
