Abstract

The invention discloses an emergency broadcasting system with a Beidou satellite data transmission function. The system comprises a Beidou RDSS transceiver module group BDM900 and further comprises astandard SIM card seat, a P-MOSFET field effect transistor Si7617DN, and a processor STM32F103ZET6 with a Cortex-M3 core. The transceiver module BDM900 comprises a communication pin RXD0, a communication pin TXD0, a power supply pin VCC _ PA _ IN, a power supply pin VCC _ RX _ BAT and a power supply pin VCC _ RX _ CTR. The processor STM32F103ZET6 comprises a PA1 pin, a PA2 pin, a PA3 pin and a PA4pin. The communication pins RXD0 and TXD0 are respectively connected with the PA2 pin and the PA3 pin; a VCC _ RX _ CTR pin is connected with a PA1 pin, a power supply pin VCC _ PA _ IN and a power supply pin VCC _ RX _ BAT are both connected with a drain electrode end of a P-MOSFET Si7617DN, and a grid electrode G is connected with a PA4 pin. According to the invention, the Beidou RDSS / RNSS short message data communication positioning module is adopted to realize bidirectional data communication / positioning and voice broadcasting of all levels of indoor intelligent ecological broadcasting platforms and outdoor intelligent ecological broadcasting terminals.

Description

technical field [0001] The invention relates to the technical field of speaker broadcasting devices, in particular to an emergency broadcasting system with a Beidou satellite data transmission function. Background technique [0002] In recent years, broadcasting has played an increasingly important role in people's daily life. At present, all provinces, cities, and counties are building their own emergency broadcasting systems, and three transmission channels of IP / FM / DTMB have been formed in various places to complement each other. Communication "pipeline" solutions, but these communication paths are all ground signal transmission channels. After devastating natural disasters such as earthquakes and typhoons, ground data transmission channels are often interrupted due to damage. Therefore, there is an urgent need for satellite two-way transmission channels and ground transmission channels. Complementary to each other, platforms at all levels can carry out two-way data commu...
