Multimedia terminal control box for civil defense alarm

Abstract

The invention discloses a multimedia terminal control box for civil defense alarm. The multimedia terminal control box comprises a center control module, an environment sensor network processing module, a network communication module, an audio and video processing module, a power module, and a display module. The center control module is connected with the environment sensor network processing module, the network communication module, the audio and video processing module and the power module. The display module is connected with the audio and video processing module. The audio and video processing module comprises an audio and video decoding control module, an audio and video input module, an audio and video output module and an audio power amplifier module. The multimedia terminal control box has multiple communication capabilities, and can steadily provide information like alarming notice, disaster defense and emergency rescue under an emergency state for the public. Since the control box has audio capture equipment and video capture equipment, a mutual monitoring function can be achieved, and customer demand information can be fed back to a terminal for providing real-time inquiry. By the aid of the multimedia terminal control box, real-time playing of information like images, texts and audios and videos of a command center can be achieved. Through a human body inductive sensor and a light sensor module, intelligent control to a power supply and screen luminance can be achieved, and the multimedia terminal control box is energy-saving.

Description

technical field [0001] The invention relates to the field of civil air defense alarm systems, in particular to a multimedia terminal control box for civil air defense alarms. Background technique [0002] At present, the air defense warning communication mainly realizes the remote control signal distribution of the warning through wired and wireless means. The anti-destruction ability of the wired method is relatively weak; the stability of the wireless method is greatly disturbed by the outside world, and it is vulnerable to attacks in a war environment, which directly affects the reliability of the air defense alarm. At this time, TV and radio forecasts will lose their effect. The wireless remote control system of civil air defense alarm may not be able to activate the alarm equipment due to information suppression. Once the air defense alarm central control system is attacked by the enemy, the entire network will be paralyzed. The existing technology usually adopts multi...

AI Technical Summary

Problems solved by technology

The anti-destruction ability of the wired method is relatively weak; the stability of the wireless method is greatly affected by external interference, and it is vulnerable to attacks in a war environment, which directly affects the reliability of air defense alarms. Air strikes must be accompanied by omnidirectional, full-time, and full-frequency At this time, TV and radio forecasts will lose their effect. Civil air defense alarms relying solely on wireless remote control systems may not be able to activate alarm equipment due to information suppression. Once the air defense alarm central control system is attacked by the enemy, the entire network will be paralyzed.

The existing technology usually adopts multimedia alarm systems such as indoor, corridor and underground space, but these technical solutions do not consider the interaction with the terminal crowd, and can only passively accept superior orders to complete the control task

In addition, for the video information broadcast by the command center, the alarm system of the prior art cannot meet the needs of real-time broadcast
