Field-type integrated intelligent emergency broadcasting terminal

Abstract

The invention discloses a field-type integrated intelligent emergency broadcasting terminal, which comprises a main engine module, a power amplifier and a power management module, wherein the main engine module realizes multichannel transmission, coverage and receiving of a broadcasted emergency signal, text and video playing functions and remote equipment monitoring; the power amplifier amplifies an audio signal inputted by the main engine module for driving multiple load horns or driving the load horns after remote transmission; and the power management module is mainly used for providing working voltage for the main engine module and the power amplifier, a power backup function is provided, and seamless switching of equipment power supply, long-time endurance under high-power operation and automatic and periodical battery maintenance are realized. The field-type integrated intelligent emergency broadcasting terminal has the advantages that the reliability of the emergency broadcasting system is improved; the broadcasting modes are enriched; the monitoring ability of the emergency broadcasting system on the terminal equipment is enhanced; and the broadcasting coverage and the independent operation ability of the emergency broadcasting system are enhanced.

Description

technical field [0001] The invention relates to the technical field of radio and television communication, in particular to an outdoor integrated intelligent emergency broadcast terminal. Background technique [0002] Emergency broadcasting refers to an important authoritative channel for the government to broadcast emergency news to the public, provide information services, and assist disaster relief and rescue when natural disasters, accident disasters, public health and social security and other public emergencies occur. important means. The emergency broadcast system mainly includes emergency broadcast management platform, transmission coverage network and emergency broadcast terminal. Among them, the emergency broadcast terminal is mainly used to receive daily broadcast and emergency broadcast signals, and is an important part of the emergency broadcast system.

Problems solved by technology

Among them, the emergency broadcast terminal is mainly used to receive daily broadcast and emergency broadcast signals, and is an important part of the emergency broadcast system. At present, the common field emergency broadcast terminal mainly has the following deficiencies, which are difficult to meet the needs of the market

It can only receive frequency modulation (FM) or terrestrial wireless TV signals (DTMB), and broadcast emergency transmission channels are limited. When a disaster occurs, once the FM and terrestrial digital transmission channels fail, broadcast emergency cannot be performed, so the emergency broadcast system cannot be guaranteed reliability

[0003] 1. Lack of remote monitoring of the equipment, unable to remotely read the working status parameters of the field emergency broadcast terminal, which increases the manpower and time costs of equipment operation and maintenance

[0004] 2. Although the power amplification function is integrated, the power is small (generally 25W), and the load capacity is insufficient, so it cannot drive multiple horn loads at the same time or drive horn loads for long-distance transmission, that is, the coverage of a single field emergency broadcast terminal Small

[0005] 3. The form of broadcasting is relatively single, mainly based on sound broadcasting, which cannot be broadcast to the audience in the form of text or video, and cannot meet the needs of diversity and comprehensive three-dimensionality of broadcasting and publicity

[0006] 4. Mains power supply is generally used, and there is no power backup function. If the mains power supply is interrupted, the system will not be able to receive emergency signals for broadcasting, which means that the existing equipment has poor independent operation ability
