摘　　要：提出了一种直流母线式的有蓄电池有逆流发电系统结构。使用智能单相电能表作为电能信号的采集终端,将采集所得的各种电能信号采用MODBUS-RTU通讯协议通过485总线传输至485/USB转换器,再由转换器送至上位机进行读取。上位机的各种控制指令通过XBee无线传输模块发送给现场单片机控制模块,由单片机实现对现场设备的控制。通过LabVIEW开发平台编写可视化较强的上位机界面,并利用WEB发布技术将前面板发布至网络上进而实现运程监控。通过测试及分析,结果显示整个系统运行良好、稳定、实时性强。A kind of dc bus type with reflux and battery power generation system structure is put forward.Using intelligent single-phase watt-hour meter as electricity signal acquisition terminal,the acquisition of various signals are transferred to the485/USB converter through 485 bus,which using the MODBUS-RTU communication protocol,then the signals are sent to the PC from converter to read.The MCU receives control instructions from PC through XBee wireless transmission module to control field devices.By LabVIEW development platform the pc can make strong visual interface and through the WEB publishing technology the front panels are released to the network to achieve the remote control.Through test and analysis,the system has strong real-time property and runs well and stable.
