摘　　要：应急广播大扬声器系统是目前我国应急广播建设中开展快、覆盖范围广、群众基础好的一个环节。目前全国范围内有大量的省、市、县都在开展应急广播大扬声器系统的相关建设,如何确保建成的系统符合统一标准,保障系统的兼容性和可扩展性成为一个重要课题。本文将按照广电总局现有应急广播大扬声器技术要求,提出一种应急广播自动化测试流程,为日后应急广播大扬声器系统和设备的标准化测试提供一种快捷和规范的测试流程参考。With quick development, wide coverage and good foundation of the masses, emergency broadcasting loud-speaker is a very important part of emergency broadcast system. Nowadays, it has been developed in lots of areas over the Country-. Then how to keep its uniform, compatibility and scalability should be focused on. The article proposes an auto test process for emergency broadcast system based on requirements of State Administration of Radio Film and Television （ SARFT）, which provide a quick and standard test reference for emergency broadcasting loud-speaker system and equipments.
