基于模块化的山洪灾害预警音频数字功放系统设计
Design of audio digital power amplifier system for mountain flood disaster warning based on modular design
摘要
Abstract
The early warning of mountain torrent disaster is an important part of water conservancy informationization,and the early warning broadcast function is an important link in the early warning of mountain torrent disaster.In order to solve the problems of the existing mountain torrent early warning system,such as low efficiency of broadcast,bulky equipment,inconvenient installation,high cost of fault treatment,low efficiency of power supply and complex control,a digital audio power amplifier system based on modular design for water conservancy mountain torrent early warning is proposed.The power supply input,audio signal output,digital power amplifier and audio chip,control input and other modules are integrated in the telemetry intelligent terminal.Form a compact,efficient early warning system core,the use of Mini-PCIe module design,combined with customizable voice chip and 15 W class D dual-channel audio power amplifier,so that it has pluggable,easy installation,convenient maintenance and other functions,in order to achieve efficient and stable voice broadcast function.关键词
