环境噪声测试终端采集传输系统的设计
 摘要:目前，我国水体污染和空气污染自动监测己经具有相当的规模和技术，而城市环境噪声的监测方式远远滞后于环保的需要和技术的发展，无法对污染进行及时准确的监测。若噪声监测可以在城市范围内大量布点，并实现无人操作远距离测试，则将大大提高环保监测的自动化程度和工作效率，增强环保部门对噪声污染、噪声超标排放的快速反应能力和监控能力。本论文是基于GPRS技术的环境噪声测试终端采集传输系统的研究与设计，根据课题的实际要求提出了整体设计方案和原理框图。接着从硬件和软件设计两方面对测试终端的设计做了详细的说明。在硬件设计方面，本文从数据采集处理模块设计等方面讨论了测试终端的硬件设计解决方法。在软件设计方面，以W77E58单片机为核心，详细阐述了测试终端的软件设计思想、主流程图、实现相应功能的子流程图以及程序源代码。最后对该系统进行了户外机箱结构的设计。测试终端将噪声数据及时、准确地通过GPRS网络传给环境监督管理部门。为环境噪声监测和治理提供有效的依据，对推动环保领域的技术进步和科技发展具有十分重要的现实意义。

Test collection and transimission terminal system of environmental noise
 Abstract: At present, the auto monitoring of water and atmosphere has possessed quite scope and technique in china. But the method of monitoring urban environment noise lags far behind the needs of environmental protection and technological development, so we unable to timely and accurate monitoring of noise pollution. If the noise monitoring could distribution in a large number within the city and to achieve unmanned operation of remote test, the environmental monitoring department will greatly enhance the degree of automation and efficiency at the same time the environmental protection department will greatly enhance the rapid reaction capability and monitoring capabilities of the noise pollution and excessive noise emissions. This thesis is environmental noise testing terminal research and design, which is based on GPRS technology. Responding to the requirement of the project, this paper offers the scheme and the principle frame. The following elaboration about the design of the terminal detection is given from the angle of software and hardware. For hardware designing, it discusses the designs and the ways of the terminal detection from the data—acquisition module and the GPRS communication module. As for software, it elaborates the main idea of this terminal detection designment, the main flow chart, the corresponding functional flow chart and the source code according to W77E58.Finally I designed the outdoor enclosure structure of the system. The terminal detection will immediately and exactly send the data of noise to some administer department about environment—protecting by GPRS, which will offer effective data for the noise detection and disposal. In addition, it’ll offer effective measure for the noise detection and there is important significance for further development of the technology and science in the field of environment-protecting．
