Further, the step 8 of playing the emergency broadcast message through a loudspeaker, a television or an outdoor large screen is synchronous playing, repeated playing, timed playing and on-demand playing.
The invention has the beneficial effects that:
1) the emergency broadcast message is remotely transmitted to the unmanned aerial vehicle through a broadcast television signal transmission network. The unmanned aerial vehicle is high in position, and can receive broadcasting television signals remotely transmitted by other places. When the local wireless network and the local broadcast television transmission network are interrupted due to disasters, the emergency broadcast platform can transmit emergency broadcast messages to the unmanned aerial vehicle by using the non-local broadcast television transmission network, and the system is stable and reliable.
2) The receiving device of the unmanned aerial vehicle remotely receives the broadcast television signals to obtain the emergency broadcast messages, and the local broadcast television broadcasts are carried out through the transmitting device of the unmanned aerial vehicle, so that the large-range coverage of the local emergency broadcast messages is realized, the local emergency broadcast messages can cover dozens of kilometers, and the coverage range is large.
3) And the local emergency broadcast receiving terminal receives broadcast television signals containing the emergency broadcast messages to obtain the emergency broadcast messages, outputs audio and video for broadcasting, and establishes a local wireless local area network for network push or on demand. The emergency broadcast message can be completely received on the ground, and the stable broadcast and the repeated broadcast are realized.
4) And converting the content form of the emergency broadcast message, wherein the content form comprises characters, images, audio or audio and video, and outputting the emergency broadcast message in the corresponding content form to a loudspeaker, a television or an outdoor large screen for playing according to the difference of playing ends. The broadcasting can be realized by adapting to different broadcasting ends, the broadcasting form is diversified, and people with hearing impairment, visual impairment and low literacy rate can receive emergency broadcast messages.
5) The emergency broadcast message is provided for a mobile phone, a tablet and a computer which are accessed to the wireless local area network in a push or on-demand mode. The network requests the emergency broadcast message, and the same emergency broadcast message can select versions with different content forms. The network broadcasting mode is diversified, and people with hearing impairment, visual impairment and low literacy rate can receive emergency broadcast messages.
