摘要长期以来城市居民生活用水、用电和用气的计量都是依靠供方企业人工抄录，但是随着城市规模的不断扩大以及水、电、气在广大农村的普及，低效率的传统的人工抄表方式已经无法适应现代企业发展的需要，因此实现自动抄表具有重要的现实意义。74054

物联网技术的发展和进步为抄表系统带来了新的解决方案，即通过物联网将仪表数据传输到企业，实现自动化抄表。本文从实际应用需求方面出发，在学习和研究物联网的基础上提出和设计了基于ZigBee近距离无线通信技术和GPRS远程无线传输技术的分布式无线电表抄录系统。整个系统包含仪表数据采集终端、数据集中器和数据管理中心三个部分。数据采集终端主要负责的是仪表数据的采集并通过ZigBee无线通信将数据传输到数据集中器；数据集中器主要负责的是通过ZigBee接收电表数据，通过显示屏实时显示用户用电量，并定期通过GPRS将数据发送到数据管理中心；数据管理中心主要负责的是数据接收、显示、存储和管理。

Design of Wireless Meter Reading System Based on Internet of Things

Abstract For a long time, the instrument measurement of urban residents living water, electricity and gas depends on supplier manual transcribing。 However, with the enlargement of city scale and the popularity of water, electricity and gas in the rural, the low efficiency of traditional manual meter reading way has been unable to adapt the needs of the development of modern enterprise, so it has important practical significance to realize automatic meter reading。

The development and progress of Internet technology bring meter reading system a new solution, that is implements wireless meter reading by sending meter data to the enterprise using internet of things technologies。In this paper, starting from the actual application requirements, on the basis of the study and research the Internet of things was proposed and designed based on ZigBee close range wireless communication technology and GPRS remote wireless transmission technology of distributed wireless electric meter transcription system。 The whole system includes the instrument data collection terminals, data concentrator and data management center three parts。 Data acquisition terminal is mainly responsible for instrument data acquisition and through the ZigBee wireless communication to transmit data to the data concentrator; Data concentrator is mainly responsible for is through the ZigBee receive electric meter data, through the display real-time display user of electricity, and regularly through GPRS sends the data to the data management center; Data management center is mainly responsible for receiving, data display, storage and management。
