摘要
山洪灾害预警是水利信息化中的重要部分,而预警播报功能是山洪灾害预警中重要的一环.为解决现有山洪灾害预警系统预警播报效率不高、设备体积大、安装不便、故障处理成本高、电源利用效率低、控制复杂等问题,本文采用Mini-PCIe模块设计水利山洪灾害预警音频数字功放系统,结合可定制化的语音芯片和15W D类双声道音频功率放大器,将功放音频的电源输入、音频信号输出、数字功放与音频芯片、控制输入等模组集成于遥测智能终端内,形成一个紧凑、高效的预警系统核心,使其具备可拔插、简便安装、便捷维护等功能,以实现高效稳定的语音播报功能.
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.
