Android平台智能抄表应用软件程序设计(论文11600字)
摘要
在我们的社会生活中，电表、煤气表等的抄录和收费是必不可少的日常。以前的抄表方式以有线方式为主，主要有电话线方式、电力线载波方式等等。慢慢随着社会城市的不断进步和发展，智能化城市已经成为一种趋势，有线抄表方式也渐渐变得不够满足需求。有线抄表方式存在很多弊端，布线复杂，施工时间长，安装和维护的成本高等。所以寻求一种无线的传输方式，设计一种自动智能抄表系统成为了关键。
本次课程设计是对煤气智能无线抄表方式的研究，基于lora物联网络，通过将lora技术和手机APP结合，形成无线抄表创新远程组网模式。Lora是一基于扩频技术的超远距离无线传输技术。Lora具有较强的抗干扰能力，而且传输距离远，应用在无线抄表上有很大的优势。这款基于Android平台的智能抄表APP可以自动连接lora，验证抄表员的信息，通过无线抄表方式，获取燃气表的信息数据。同时，抄表员可以实时获取数据并保存上传给公司，燃气公司也方便对信息数据存储和管理。

Abstract
In our social life, the transcription and charging of electric meters, gas meters, etc. are essential everyday. The previous method of meter reading was mainly wired, mainly including the telephone line method, power line carrier method, and so on. Slowly with the continuous progress and development of social cities, smart cities have become a trend, and cable meter reading methods have gradually become inadequate to meet demand. There are many disadvantages in the wired meter reading method, the wiring is complicated, the construction time is long, and the cost of installation and maintenance is high. So seeking a wireless transmission method, designing an automatic smart meter reading system has become the key.
The design of the course is a study of the smart wireless meter reading method for gas. Based on the lora material network, the wireless remote meter reading model is formed by combining the lora technology and the mobile phone APP. Lora is a super long-distance wireless transmission technology based on spread spectrum technology. Lora has a strong anti-interference ability, and the transmission distance is far, and it has a great advantage in wireless meter reading. This Android-based smart meter reading APP can automatically connect to the lora, verify the meter reader's information, and obtain the gas meter's information data through wireless meter reading. At the same time, the meter reader can obtain data in real time and save it for upload to the company. The gas company also facilitates the storage and management of information data.
