智能水电气表自动抄表系统

摘要：远程数据的采集与传输在实时数据通信系统中占有重要的地位。通过远程数据采集与传输系统实现了住宅小区智能化管理，适应了住宅小区智能化建设和公共事业管理部门加强管理、改善服务的需要。传统的小区管理采用人工上户抄表的方式，浪费大量人力物力，用电、水、等管理工作劳动强度大，而远程抄表系统具有廉价、可靠、方便、开放的特点。进一步开发研究，可实现远程控制、系统监控等功能[1]。
    远程抄表系统是以远程数据采集与传输系统理论为基础的小区智能化管理系统的重要组成部分。其中的数据采集与传输是本论文研究的主要内容。文中分析了远程抄表系统中的数据采集、存储、传输等问题，研究了各种数据总线原理及应用，研究和设计了远程抄表系统总线、终端采集器模块、集中器等内容。
    本论文研究的各种数据总线包括仪表总线Meter-Bus, RS.485总线、电力线载波通信等的原理与应用设计;远程抄表系统总线终端采集器模块的设计主要包括仪表总线终端收发芯片TSS721的原理及应用，RS.485总线终端电平转换芯片简介，采集器模块的微处理器及EEPROM芯片的采用和电路连接设计，数据采集模块的软件流程设计等内容;集中器模块设计包括集中器的微处理器与外围设备的电路连接设计，集中器的控制器与各类通信方式之间接口芯片的采用和转换电路的设计，集中器的工作流程设计等问题。
    远程抄表系统应用于居民小区中，既节省了传统人工抄表方式的人力物力，又具有读数准确、快速方便的优点，可以防止用户恶意拖欠付费，保证按时收费。该系统的应用适应了住宅小区智能化建设和公共事业管理部门加强管理、改善服务等方面的需要，具有较好的应用前景[2]。

The intelligence water electricity watch copies the form system  automatically

ABSTRACT：Remote data reading and transfer takes an important position in real.time communication system. Remote data reading and transfer system makes intelligent management feasible, and satisfies the need of neighborhoods intelligence construction and strengthening management and improving service of public department. It is a traditional way to do meter.data copying by hand that wastes lots of manpower. The management of electricity and water use takes much work. The Automatically Reading system is cheap, reliable, convenient and open. Through further development and research, functions of remote command and supervision can be realized
    The Remote Reading system is a neighborhoods intelligence management system based on the theory of remote data reading and transfer. The main content of this article is about data reading and transfer. In this article, how to realize the functions of the Remote Reading system through reading, storing and transfer of data is analyzed 。As well, contents about theories and application of intelligence data bus, the terminal reading module and center module are also concerned.
    The theory and application design of Meter-Bus, RS.485 and Power line communication; Theories and application of M-Bus terminal transceiver TSS721, RS.485 bus terminal transfer chip, the adoption of microprocessor and EEPROM, circuitry connection design and workflow design are discussed in the part of Remote Reading system bus terminal collector module; the circuitry connection of microprocessor of central equipment, the design of chip and transfer circuitry, the workflow design of the collector are discussed in the part of collector design module.
    The Remote Reading system is widely used, correct, fast and convenient, in the residential areas, which economizes on the manpower and prevents the delay of paying charge. The development and creation of these systems satisfy the need of residential areas intelligence construction and strengthening management and improving service of public department.
