An information broadcasting system that is fully automated and user-friendly. The system includes an Information Device that transmits a signal to a Device Server. The Device Server process the transmitted signal which includes a unique identification code for the Information Device. The information is processed by the Device Server in accordance with rules provided by the user and stored in a database. The server then transmits messages to entities previously designated by the user in formats designated by the user, such as email, pagers, text messaging, instant messaging, pre-recorded telephone messages or any other form.

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.
