[0023] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of the emergency broadcast fusion terminal based on BeiDou short message and satellite flash technology proposed by this utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0024] This embodiment provides an emergency broadcast fusion terminal based on BeiDou short message and satellite flash technology, such as Figure 1 As shown, the emergency broadcast fusion terminal based on BeiDou short message and satellite flash technology includes a main control MCU, a BeiDou short message module, a BeiDou positioning & 4G module, a satellite flash module, an FM receiver module, an IP network port, an audio switching module, an audio amplifier module, and a speaker. The main control MCU is electrically connected to the BeiDou short message module, the BeiDou positioning & 4G module, the satellite flash module, the FM receiver module, the IP network port, and the audio switching module. The audio switching module is electrically connected to the audio amplifier module, and the audio amplifier module is also connected to the speaker. The main control MCU receives emergency data collected by various sensors through a UART expansion interface or a 485 expansion interface.

[0025] It should be noted that this fusion terminal has reserved acquisition interfaces (UART external interface / 485 external interface) to receive relevant emergency data (such as earthquake intensity, rainfall, etc.) collected by various sensors (such as earthquake sensors, meteorological sensors, etc.), and finally upload the corresponding emergency data to the emergency broadcasting platform.

[0026] Preferably, such as Figure 2As shown, the emergency broadcasting fusion terminal based on BeiDou short message and satellite navigation technologies communicates with the emergency broadcasting front-end. The emergency broadcasting front-end includes an emergency broadcasting platform, a BeiDou short message front-end transmitting system, an IP distribution server, 4G & 5G modules, and an FM transmitter. Specifically, the emergency broadcasting platform transmits short message information and control information to the BeiDou short message module through the BeiDou short message front-end transmitting system; the emergency broadcasting platform transmits control signals and audio signals to the IP network port or the BeiDou positioning & 4G module through the IP distribution server / 4G & 5G module; the emergency broadcasting platform transmits modulated signals and control commands to the FM receiving module via the FM transmitter; the emergency broadcasting platform can broadcast to the fusion terminal through the BeiDou short message module, IP network port, BeiDou positioning & 4G module, and FM receiving module; the emergency broadcasting platform can also select individual fusion terminals for broadcasting based on their location information, or perform multicasting.

[0027] In this embodiment, as Figure 1-2 As shown, the BeiDou positioning & 4G module acquires the real-time geographical location information of this emergency broadcast fusion terminal. Simultaneously, it receives relevant emergency data (such as earthquake intensity and rainfall) collected by various sensors (e.g., earthquake sensors, meteorological sensors) at the emergency site via a UART or 485 external interface. The main control MCU then transmits the acquired geographical location information and emergency data to the emergency broadcast platform via the IP network port or the BeiDou positioning & 4G module. If the IP network port or the BeiDou positioning & 4G module's transmission channel malfunctions, the geographical location information and emergency data can be sent to the emergency broadcast platform via the BeiDou short message module. Upon receiving the geographical location information and emergency data, the emergency broadcast platform analyzes and processes them to generate corresponding emergency broadcast content. Then, the emergency broadcast platform transmits the emergency broadcast content to various emergency broadcast fusion terminals within a certain range via the BeiDou short message front-end transmission system, IP distribution server, 4G & 5G module, and FM transmitter. After receiving the emergency broadcast content, the emergency broadcast fusion terminal plays the content according to its own location information and the requirements of the emergency broadcast content.
