LonWorks技术智能抄表系统的设计

Design of Intelligent Meter Reading Based on LonWorks Technology

为了建立智能社区系统,设计了一种基于LonWorks现场总线技术的智能抄表系统。系统通过在抄表采集器内置神经元芯片和LonWorks双绞线收发器,接收和计算各种计量表具发出的脉冲,从而得到表具实际读数。该数据最后以网络变量的形式,通过收发器传至LonWorks网络,实现管理上位机与抄表采集器之间的数据通信。试验证明,系统运行可靠,能有效地解决人工抄表方式带来的诸多弊端,具有一定的应用价值。

To establish intelligent community system,the intelligent meter reading system based on LonWorks fieldbus technology is designed.Through installing neuron chip and LonWorks twisted-pair transceiver inside the meter reading collector,the system receives and calculates the pulses sent out by various meters,thus obtains the actual readings of meters.These data are then sent to the LonWorks network via the transceiver in the form of network variables for implementing data communication between host PC and meter reading collector.The experiment proves that the system runs reliably and can effectively solve many abuses of reading meters manually.The design possessescertain applicable value.
