Abstract

The invention provides a multi-power-supply type emergency early-warning acoustic image transmission system. The system can achieve an acoustic early-warning function and back transmission of site images. An image collecting unit and a back transmission unit are used for collecting and back transmitting of the images. A central control unit controls switching of working modes and controls collecting of image information and the working order of image back transmission, and accordingly power consumption is lowered. An efficient power amplifying circuit and a multi-power-supply system guarantee stable system power supply, and energy is saved.

Description

technical field [0001] The invention relates to a receiver, which can be used for the transmission of audio and image signals, in particular to a multi-power supply emergency warning audio and video transmission system. Background technique [0002] When natural disasters (mountain floods, mudslides, etc.) occur, the power system is often paralyzed. If the emergency warning receiver only uses a single mains power supply, when a natural disaster occurs, it will not work normally due to the interruption of the power supply, and the effect of emergency warning will not be achieved. [0003] If the early warning receiver can send the on-site information back to the control center, it will be of great help for emergency disaster reduction. Based on the returned information, the on-site disaster situation can be understood more quickly, and a more powerful rescue and disaster relief plan can be formulated. [0004] The increased backhaul function will also increase the power con...
