Multi-channel emergency broadcast intelligent terminal system and control method based on priority

Abstract

The invention discloses a multi-channel emergency broadcast intelligent terminal system and a control method based on priority. The multi-channel emergency broadcast intelligent terminal system comprises a multi-channel receiving module, a main control module, a power supply module and a power amplifier module, wherein the multi-channel receiving module mainly consists of a direct broadcast star receiving component, a wired digital television receiving component, a ground digital television receiving component, a medium wave receiving component and a frequency modulation receiving component; the multi-channel receiving module is used for receiving and processing input signals of multiple channels and used for demodulating the received signals and subsequently transmitting to the main control module for signal and data processing. Compared with a conventional emergency broadcast intelligent terminal, the multi-channel emergency broadcast intelligent terminal system adopts main-standby double-power supply design and multi-channel design based on priority, so that the power calamity resistance and the channel calamity resistance of the emergency broadcast intelligent terminal are improved. Due to adoption of double-feedback network design, not only is the network calamity resistance of the emergency broadcast intelligent terminal improved, but also the management control and feedback functions of the emergency broadcast intelligent terminal are greatly improved.

Description

technical field [0001] The invention is applicable to the technical field of emergency broadcasting, relates to an emergency broadcasting terminal system, and in particular to a priority-based multi-channel emergency broadcasting intelligent terminal system and a control method. Background technique [0002] With the rapid development of the economy and the acceleration of industrialization and urbanization, the pressure on public health safety, enterprise production safety, and road traffic safety is gradually increasing, especially at the critical moment of economic development and social transformation at this stage. A variety of traditional and non-traditional, natural and social, international and domestic risk contradictions coexist, the probability of public emergencies has increased significantly, and for a long time to come, they will still face the risks brought about by public emergencies. ordeal. Therefore, it is increasingly urgent and important to establish an...

Problems solved by technology

However, most of the current emergency broadcast terminals are one-way transmission devices with a single channel and simple functions. It is possible that this is precisely the moment when the emergency broadcast terminal plays a key role

Secondly, the controllability is poor. The one-way emergency broadcast terminal cannot communicate with the emergency broadcast management platform. The emergency broadcast management platform can neither perform remote maintenance and management of the emergency broadcast terminal, nor can the emergency broadcast terminal The information is fed back to the emergency broadcast management platform, making it impossible to evaluate the effectiveness of emergency broadcasts

Again, the security is poor. The emergency broadcast terminal lacks security processing for emergency broadcast control commands, and cannot guarantee the legality of emergency broadcast control commands.
