为了保障剧院表演者的表演效果、观众的观看感受和自动化舞台设备的正常运行，国家对剧院观演空间环境温湿度、二氧化碳、背景噪声等多个参数进行了标准规定。目前国内外剧院环境参数测试均采用人工独立测试，没有集成化、自动化测试系统。为此，本文采用ARM嵌入式技术对多参数进行实时采集、处理、显示以及通过以太网的形式将环境参数传输到其他系统进行集中管理、远程监控和数据存储等。系统硬件主要由ARM内核微控制器为核心的主控电路、RS485通信接口、LCD液晶显示触摸屏以及支持Modbus RTU协议的若干环境传感器等组成；系统软件是在移植UCOSII操作系统、LWIP网络协议栈的基础上，完成了各功能模块的程序设计。通过系统调试，结果表明该系统具有较高的可靠性、稳定性和扩展性，可以很好的完成剧院观演空间环境参数自动测试任务，具有一定的实用价值和应用前景。

Toenure the performance effect of performers, the watching feeling of audience, and the normal operation of automatic stage equipment，a national standard is made, including the temperature and humidity, carbon dioxide, background noise, and other environmental parameters in the theater. Now, both domestic and overseas adopt independent manual testing without an integrated and automated measurement system. To this end, this paper applies an embedded technology based on ARM to collect, process, display the parameters in time and transmit the environmental parameters to other systems in the form of Ethernet for centralized management, remote monitoring and data storage. The system hardware is mainly composed of the main control circuit with ARM core microcontroller as the core, RS485 communication interface, LCD touch screen, and several environmental sensors supporting Modbus RTU protocol. The system software completes the program design of each functional module based on transplanting the UCOSII operating system and LWIP network protocol stack. Through the system debugging, the results show that the system has high reliability, stability, and expansibility, and can well complete the automatic test task of environmental parameters of theater. It has certain practical value and application prospects.
