摘要随着时代的发展，老式的水表已经渐渐地显露出弊端，一方面他不利于供水部门对水表的查抄，供水部门对水表进行查抄和统计的时候，需要依靠人工来逐个记录，这样不但耗时耗力，而且还会有时因为人工的误计而造成数据的偏差；另一方面，因为老式的水表大多都安装在楼层下的井盖内，这样也十分不方便用户实时的查看自己的用水情况。因此本课题针对这些方面，设计了一套简洁有效的远程水表采集系统方案。46102

本方案是一种新型的水表采集方式，将移动的公共通讯平台和监控系统组合在一起远程数据采集系统，并且可以通过手机终端或者PC机远程的收集数据，它的特征是高效、高质、经济实用，非常适合小区用户的水表信息监控。我们主要是对传统水表的改造升级，然后使用PLC来控制其对水表数据的采集，最后通过安装的GPRS无线通讯模块将采集到的数据发送到用户终端，我们采用了PLC来进行数据采集的原因是它的可靠性很高，并且操作性强，而且可以支持功能的拓展，以满足以后各种新功能的添加。
本方案不但适合于用户水表的采集，如天然气、用电量的远程采集也可以以此为基础进行拓展，本方案的思路不但适合与民用，就连工业上的远程数据采集也是行之有效的。

Abstract
With the development of the times, the old water meter has been gradually revealed drawbacks, on the one hand he is not conducive to the water sector to check the water meter, when the water conservancy company need to check the water meter, the have to rely on peopel recorded one by one, so not only time-consuming labor-intensive, but also sometimes caused by erroneous meter data because of the artificial deviation; on the other hand, because most of the old water meters are installed in the floor under the covers, It is inconvenient for the user to view their real-time water situation. Therefore, this paper for these areas has designed a simple and effective remote meter-acquisition system.
The program is a new way of collecting meter, mobile communications platform for public and monitoring systems combined remote data acquisition system, and can collect data through mobile terminals or PC remote, it is characterized by high efficiency, high quality, economical and practical, very suitable for residential users of water meter information monitoring. We are mainly on the traditional meter of upgrading, and then use the PLC to control the collection of meter data, and finally through the installation of GPRS wireless communication module the collected data is sent to the user terminal, we have adopted a PLC for reasons of data collection it is highly reliable and easy to operate, and can support the expansion of functions to meet various later add new features.
The program is not only suitable for the user meter collection, such as natural gas, electricity consumption can also be remote collection as a basis for development, the idea of this program is not only suitable for civilian use, and even the remote data collection Industrial also works well .
