There are two kinds of data collection boxes, box A and B. Box A is set beside the combiner box outdoor. Programmable Automation Controllers (PAC)made by National Instrument (NI) are used as the data acquisition unit (DAQ unit) in Box A. They are NI 9073 integrated chassis and controller, NI 9205 and NI 9217 acquisition module. 
数据收集箱有两种类型,箱A和B,箱A设置(在户外组合框的旁边。由美国国家仪器公司(NI)制造的可编程自动化控制器(PAC)放在箱A内用作数据采集(DAQ单元),包括NI9073底盘集成控制器,NI 9205和NI 9217采集模块。

Some current and voltage sensors made by LEM company and a PT100 temperature sensor are also installed in Box A. Box B is set indoor and it consist of NI9073, NI 9205, a DC voltage sensor, a DC current sensor, AC current transformers, SIEMENS SENTRON PAC 3200 and 4200 power meters, etc. 
一些由LEM公司制造的电流、电压传感器和PT100铂电阻温度传感器也安装在箱A内。箱B内(箱B放置在室内放置(包含NI 9073,NI 9205,直流电压传感器,直流电流传感器,电流变压器,西门子新创PAC 3200和4200功率计等。

The meteorological data collection system consists of a CR1000 data logger made by CAMPELL company, pyranometers, reference cells, a temperature sensor, an anemometer, a wireless transmission s station, etc. CR1000 data logger is used as DAQ unit. The circular point indicates measurement points for the PV system. The block diagram of the monitoring system is shown in Fig. 3.
气象数据采集系统由金宝公司制造的CR1000数据记录器,总日射表,参考单元,温度传感器,风速仪,无线传输站等组成。数据记录器CR1000用作数据采集单元。圆形点表示为光伏系统的测量点。监控系统的框图如图3所示。 

            图3  光伏并网发电监测系统数据采集的模块框图

The sensors in Box A, Box B and meteorological data collection system are used to collect the electrical and meteorological parameters in real time shown in Fig. 3. The collected data are transmitted to DAQ unit to be processed to necessary signals. The signals from Box A and B are transmitted to the PC by Ethernet bus while the other signals from Meteorological datacollection system are transmitted by a wireless station. 
在图3中显示:盒A、盒B里的传感器,气象数据采集系统是用来实时收集电和气象参数的。收集到的数据传输到数据采集单元用于(加工成处理必要的信号。从盒A和B的信号通过以太网总线传送到PC机而从气象数据采集系统的其他信号可以通过无线电台传送。

The data in PC can be processed by LabVIEW (Laboratory Virtual Instrument Engineering Workbench) software. The real time data can be displayed in the on-site PC and remote PC. The internet is used to remote transmission.
PC机里的数据可以用LabVIEW(实验室虚拟仪器工程平台)软件处理,实时数据可以在现场PC机和远程PC机显示,互联网可以用于远程传输。
