    摘要:

    針對大型公共建筑能耗實(shí)時(shí)采集系統中存在的布線(xiàn)復雜、通信成本高、安全性低等問(wèn)題,提出一種基于ZigBee技術(shù)的能耗數據采集器設計方案。該方案采用STM32做主控制器, ZigBee采集單元通過(guò)RS485接口實(shí)現與基于Modbus協(xié)議的智能電表之間的數據通信,并采用ZigBee無(wú)線(xiàn)網(wǎng)絡(luò )將數據發(fā)送至協(xié)調器,協(xié)調器通過(guò)USART方式與主控制器進(jìn)行通信;主控制器利用以太網(wǎng)將數據發(fā)送至上位機。通過(guò)軟硬件設計,以XY194E智能電表為例,對其電能參數進(jìn)行測試采集,結果表明該方案克服了傳統人工采集傳輸的不足,提高了數據采集傳輸的實(shí)時(shí)性、準確性,能夠滿(mǎn)足能耗采集系統的要求。

    Abstract:

    To solve the problems such as wiring complexity, high communication costs and low transmission rate in the real-time energy acquisition system of large public buildings, this paper proposes a design scheme of energy data collector based on ZigBee .With STM32 as the main controller, the ZigBee acquisition unit communicate with the smart meter based on Modbus through the RS485 interface, and send them to coordinators via ZigBee internet. Coordinators communicate with the main collector by the serial port. The main controller sends data to computer via Ethernet. With the software and hardware design, take the XY194E for example, several parameters like voltage are tested. The result indicates that the scheme which overcomes the shortcomings of traditional manual acquisition and transmission, and improves the real-time and accuracy of data acquisition and transmission can meet the requirement of the energy acquisition System.
