【摘要】：電能表是智能電網(wǎng)建設(shè)的計量終端產(chǎn)品,而智能電表是目前電表行業(yè)發(fā)展的重要業(yè)務(wù)。按照目前新標(biāo)準(zhǔn)對單相智能電能表的功能和性能要求,我們采用炬泉公司生產(chǎn)的高精度計量芯片ATT7053BU,設(shè)計了一種新型單相遠(yuǎn)程智能電表,該電表不但具備高精度的計量功能,還具有數(shù)據(jù)采集、遠(yuǎn)程控制、停電檢測、雙向通訊、實時監(jiān)測等多種功能,通過與集抄系統(tǒng)的連接,實現(xiàn)對用戶需求側(cè)的管理操作。采用RS485通訊方式,通過專用的通訊線路實現(xiàn)對電能表的遠(yuǎn)程控制。本文詳細(xì)介紹了智能電表的主要功能和性能,并對硬件設(shè)計、軟件設(shè)計以及系統(tǒng)實驗做了說明。該電能表以數(shù)字電路技術(shù)為基礎(chǔ),以單片機(jī)為核心,采用集成模塊化設(shè)計的方式設(shè)計硬件電路和系統(tǒng)軟件,從而實現(xiàn)了一種單相遠(yuǎn)程智能電表。整個電路系統(tǒng)采用包括以計量部分、電源部分、時鐘部分、存儲器部分、RS485通信部分、紅外通信部分、顯示部分等多種電氣模塊連接而成。各個模塊功能獨立,而又接口統(tǒng)一,為實現(xiàn)不同功能組合和調(diào)用提供了便利。本文重點介紹電壓采樣電路、電流采樣電路、電源模塊、通訊模塊、時鐘和存儲模塊等關(guān)鍵模塊,搭配時鐘功能、存儲功能、紅外通信功能、RS485通訊功能、用電異常檢測功能、通斷電控制功能、液晶顯示功能、按鍵功能、安全認(rèn)證功能等多種模塊相結(jié)合,實現(xiàn)智能電表功能輸出要求,同時在硬件設(shè)計過程結(jié)合電能表性能要求指標(biāo),滿足用戶需求。
[Abstract]:Watt-hour meter (Watt-hour Meter) is the terminal product of smart grid construction, and it is an important business in the development of ammeter industry. According to the function and performance requirements of the new standard for single-phase intelligent watt-hour meter, we have designed a new single-phase remote intelligent meter with high precision metering chip ATT7053BU, which not only has high precision metering function. It also has many functions, such as data acquisition, remote control, outage detection, two-way communication, real-time monitoring and so on. Through the connection with the centralized reading system, the management operation on the user's demand side is realized. The remote control of the watt-hour meter is realized by using the RS485 communication mode and the special communication circuit. This paper introduces the main function and performance of intelligent ammeter in detail, and explains the hardware design, software design and system experiment. This watt-hour meter is based on the digital circuit technology, the single chip microcomputer is the core, the hardware circuit and the system software are designed by the way of integrated modularization design, thus a single-phase remote intelligent meter is realized. The whole circuit system is connected by a variety of electrical modules, including metering part, power supply part, clock part, memory part, RS485 communication part, infrared communication part, display part and so on. The function of each module is independent and the interface is unified, which provides convenience for different function combination and call. This paper introduces the key modules such as voltage sampling circuit, current sampling circuit, power supply module, communication module, clock and storage module, and so on. The key modules include clock function, storage function, infrared communication function, RS485 communication function, electric anomaly detection function, etc. The functions of power off control, LCD display, keystroke, safety authentication and so on are combined to realize the function output of intelligent ammeter. At the same time, in the process of hardware design, the performance requirements of watt-hour meter are combined to meet the needs of users.
