【摘要】：如何实现水情测报系统的自动化,是目前在水利工程领域的一个研究热点。随着物联网技术的不断发展和成熟,使得通过无线技术将传感器终端采集的数据发送到人们需要的地方成为了一种可能。为了实现在远程对水位数据进行监控和管理,我们将现有的嵌入式技术同物联网技术相结合,对无线水位传感器的设计进行了研究。本文在研究了目前国内外研究现状并在做了一部分基础实验的背景下,提出并设计了一款基于ZigBee技术的无线水位传感器系统。本系统主要包括三部分：一是以ZigBee技术为基础的无线通信网络部分,这部分的设计使用了CC2530模块,主要是为了实现传感器节点的无线组网,使得各个传感器节点采集到的数据可以进行汇总查询；二是以MSP430F2013单片机为核心的智能变送器部分,该部分利用感应式数字水位传感器对水位数据进行采集,并且将非标准电流信号转换成标准的信号,通过ZigBee模块将信号发送给协调器；三是以S3C2440为核心的嵌入式控制入网部分,这部分主要实现数据的入网功能,并且使用HTML语言编写程序,结合BOA+CGI技术实现PC机上的查询功能。本课题有如下特点： (1)在原有的传感器基础上结合了ZigBee技术,使得众多传感器节点可以进行自行组网和数据交流,而且一个传感器网络只需要一个ARM控制器即可实现众多节点数据的入网,节省了系统成本； (2)选用的变送器主控芯片功耗低,使整个系统可以运行更长的时间而不必更换电源,符合将来在实际应用领域的要求； (3)嵌入式系统部分的设计比较简单,易于操作,只需要用一个网卡便可以实现入网功能,而且S3C2440芯片还有很多接口,对进一步的开发工作很有利； (4)软件部分设计时也考虑了降低功耗的因素,编写过程中尽量使用功耗低的指令以及32位整型数据； (5)设计了网络查询页面,方便远程查询。经过实验验证后,系统基本达到了论文开始时的设计要求,实现远程数据查询功能。为将来进一步的设计完善和实践应用做了充足的准备。
[Abstract]:How to realize the automation of hydrological information system is a research hotspot in the field of water conservancy engineering at present. With the continuous development and maturity of Internet of things technology, It is possible to transmit the data collected by the sensor terminal to where people need it through wireless technology. In order to realize the remote monitoring and management of water level data, We study the design of wireless water level sensor by combining the existing embedded technology with the Internet of things technology. In this paper, we have studied the current research situation at home and abroad and done some basic experiments. A wireless water level sensor system based on ZigBee technology is proposed and designed. The system mainly includes three parts: one is the wireless communication network based on ZigBee technology, which uses CC2530 module. The main purpose is to realize the wireless network of sensor nodes, so that the data collected by each sensor node can be collected and queried; second, the intelligent transmitter part based on MSP430F2013 microcontroller. This part uses the inductive digital water level sensor to collect the water level data, and converts the non-standard current signal into the standard signal, and sends the signal to the coordinator through the ZigBee module. The third part is the embedded control network part, which takes S3C2440 as the core. This part mainly realizes the data access function, and uses the HTML language to write the program, unifies the BOA CGI technology to realize the personal computer inquiry function. This topic has the following characteristics:. 1) combining the ZigBee technology with the original sensor, many sensor nodes can organize their own network and exchange data. Moreover, a sensor network only needs one ARM controller to access the data of many nodes. The system cost is saved; 2) the power consumption of the main control chip of the selected transmitter is low, so that the whole system can run for longer time without replacing the power supply, which conforms to the requirements of the practical application field in the future; The design of embedded system is relatively simple and easy to operate, only one network card can be used to realize the network function, and there are many interfaces in the S3C2440 chip, which is very beneficial to the further development. In the software design, the factors of reducing power consumption are also taken into account, and the instructions with low power consumption and 32-bit integer data are used as far as possible in the process of writing. A web query page is designed to facilitate remote query. After experimental verification, the system basically meets the design requirements at the beginning of the paper, and realizes the function of remote data query, which makes sufficient preparation for further design improvement and practical application in the future.
