【摘要】：在我国北方地区,冬季采用集中供暖是很普遍的一种供暖方式。每年需要供暖的区域遍布全国17个省、市、自治区,占全国面积的60%以上,采暖人口达7亿以上,初步估算每年冬季单纯用于供暖所消耗的能源折合人民币近700亿元,占全国能源总消耗的四分之一左右,集中供暖又占全国整体供暖的90%以上。但是过去粗放式的集中供暖方式,容易造成大量的能源浪费,所以降低集中供暖过程中的浪费,在我国的节能减排,能源高效利用的过程中有着重要的意义,与我国低碳环保,发展绿色经济的理念相一致。我国是世界上的四大文明古国之一,具有五千年的悠久历史,在数千年的历史长河中,留下了许许多多珍贵的文物。这些珍贵的文物对于我们现代人来说是不可再生的财富,如何保护好这些财富是我们需要考虑的问题。根据在我国进行的首次“全国馆藏文物腐蚀损失调查”中显示,我国的馆藏文物近一半存在着不同程度的腐蚀和损害。而对于文物造成损害的主要原因之一就是保存环境的温度和湿度异常所导致的。除此之外,图书馆和档案馆中保存的图书和档案等馆藏物也面临着相同的问题。针对以上两种情况,本文设计了一种基于C8051的单片机温湿度网络远程监控系统,并实现之。该系统包括温湿度网络采集器节点、服务器和用户终端等。温湿度网络采集器节点采用C8051F040单片机作为中央控制器,采用AM2301作为温湿度传感器,采用CP2200作为以太网通信控制器。采集器节点可以对监控区域内的温度和湿度进行采集,通过以太网发送到服务器的数据库中。普通用户或者操作者可以通过PC终端上的浏览器或者其他客户端查看当前的实时温湿度信息,而管理者不仅可以实时查看温湿度信息,还可以设置温湿度监控的上下限、监控时段、告警信息等。本文严格按照一般的嵌入式产品设计与开发的工作流程,完成了温湿度网络采集器的电路原理图设计、PCB板设计等工作,完成了采集器样机的制作、调试和测试。同时,也完成了服务器上的网站和数据库的搭建。测试结果表明本文设计和实现的系统稳定可靠,可以应用于上述的两种情况当中。
[Abstract]:In northern China, central heating is a very common way of heating in winter. The heating needs are spread over 17 provinces, cities and autonomous regions in China every year, accounting for more than 60% of the national area. The heating population is more than 700 million. It is estimated that the energy consumed by heating alone in winter is about 70 billion yuan, accounting for about 1/4 of the total energy consumption in China. Central heating also accounts for more than 90% of the overall heating in the country. But in the past extensive central heating is easy to cause a large amount of energy waste, so reduce the waste in the central heating process, energy conservation and emission reduction in China. The process of energy efficient utilization is of great significance, which is consistent with the concept of low carbon environmental protection and green economy development in China. China is one of the four ancient civilizations in the world, with a long history of five thousand years, in the long history of thousands of years. Many precious cultural relics have been left behind. These precious cultural relics are irreproducible wealth to our modern people. How to protect these wealth is a problem we need to consider, according to the first "National Collection of Cultural relics corrosion loss Survey" conducted in China. Nearly half of the cultural relics in our country are corroded and damaged in varying degrees. One of the main causes of damage to cultural relics is the abnormal temperature and humidity of the preservation environment. Libraries and archives and other collections of books and archives are faced with the same problem. In view of the above two cases, this paper designs a remote monitoring system of temperature and humidity network based on C8051. The system includes the node of temperature and humidity network collector. The temperature and humidity network collector node adopts C8051F040 single chip microcomputer as the central controller and AM2301 as the temperature and humidity sensor. CP2200 is used as the Ethernet communication controller. The collector node can collect the temperature and humidity in the monitoring area. The user or operator can view the current real-time temperature and humidity information through a browser or other client on a PC terminal. Managers can not only view the temperature and humidity information in real time, but also set the upper and lower limits of temperature and humidity monitoring, monitoring period, alarm information and so on. In this paper, according to the general embedded product design and development process, the circuit schematic design of the temperature and humidity network collector is completed, and the PCB board design is completed, and the prototype of the collector is made. The test results show that the system designed and implemented in this paper is stable and reliable, and can be used in the above two cases.
