具体实施方式
下面通过对实施例的描述，本实用新型的具体实施方式如所涉及的各构件的形状、构造、各部分之间的相互位置及连接关系、各部分的作用及工作原理、制造工艺及操作使用方法等，作进一步详细的说明，以帮助本领域技术人员对本实用新型的发明构思、技术方案有更完整、准确和深入的理解。
基于互联网的光伏储能监控装置安装在光伏储能设备上，如图1所示，包括下位机采集模块、无线通讯模块、上位机模块和移动监控客户端，下位机采集模块实现采集数据的存储和监控，以及连接上位机模块。上位机模块通过下位机采集模块采集光伏发电系统的温度、电流、电压数据，对多个光伏发电站运行数据进行实时数据采集、分析和处理，查看实时运行情况，对运行参数进行监控，上位机模块通过无线通讯模块连接移动监控客户端，移动监控客户端可以同步本地监控主机数据。
下位机采集模块通过采集光伏发电站现场设备的运行参数和环境参数等，发送到上位机，上位机模块使用监控主机对下位机接收到的数据分类汇总、分析、处理，生成图表等，相关的数据被上位机模块内的工作站接收后进行汇总收集分析。具体的，下位机采集模块包括温度传感器、光传感器、电压电流采样调理电路、数字电位器、继电器和C8051F350单片机。采用DS18B20温度传感器和PBH1750FVI光传感器，信号处理后通过单片机传给数字电位器和继电器，同时，单片机上位机系统进行信号相互传递。
采集的电压电流信号包括光伏阵列输出的电压、电流信号，光伏储能中逆变系统的并网电流信号和电网电压信号，选用霍尔电压传感器和霍尔电流传感器。图2为霍尔电压传感器采样电路图，霍尔传感器是电流信号，在传感器的输入输出端串入电阻，转化为电压信号输入到上位机模块，具体的，输入输出端均采用三个电阻并联，使电流信号转换成电压信号，A+、A-端口连接电压采样点，V1连接到上位机模块。图3为光伏阵列电流采样电路：电流传感器LA55-P的-端口和地线之间连接并联的电解电容C1和电容C3，+端口和地线之间连接并联的电解电容C2和电容C4，M引脚接3个并联的电阻，光伏阵列电流采样电路的信号输入端连接采样点。
光伏阵列的电压电流经过电压电流采样电路输入直流信号调理电路，如图4所示，经过R1和C9组成的滤波电路，输入OP07跟随器，调节滑动电阻R9使限定电压为3.3V，信号输入至上位机模块的A/D采样通道。
由于要实现实时监控，尤其是长距离情况下，无线监控意义重大，因此无线通信方式的选择至关重要，采用2.4G无线传输模块实现无线监控。如图5所示：无线传输模块包括数据转换设备、无线接收单元和多个无线发送单元，上位机模块实际上是给数据转换设备发送命令，数据转换设备将网络命令转换成串口数据到无线发送单元，无线发送单元用大功率放大器发给两个以上无线接收单元，即使某个无线接收单元收不到信号，只要它附近的无线接收单元收到了信号，就能够将监控数据转发给它，这样使用拓展了方案的使用距离，若接收单元收到了信号，再次收到临近接收单元转发的指令，也可以增加消息的可靠性同时暂停转发。此外，无线接收单元内部设有数据触发电路，无线接收单元成功发送数据信息到移动监控客户端之后，数据触发电路收到成功发送指令，就会针对同意信号发送成功指令给相近的无线接收单元，避免移动监控客户端收到相同的数据信息。无线接收模块最终将数据发送给移动监控客户端，移动监控客户端可以同步监控主机，显示数据，对数据进行整理分析、获取运行参数、查看实时运行情况，对光伏电站进行日常管理。现在最方便使用的就是手机，不仅可以做到实时对于电站的监控，还可以降低运营成本，减少开支。
上面对本实用新型进行了示例性描述，显然本实用新型具体实现并不受上述方式的限制，只要采用了本实用新型的方法构思和技术方案进行的各种非实质性的改进，或未经改进将本实用新型的构思和技术方案直接应用于其它场合的，均在本实用新型的保护范围之内。本实用新型的保护范围应该以权利要求书所限定的保护范围为准。
