Photovoltaicinformation acquisition device

Abstract

The invention discloses a photovoltaic information acquisition device, which comprises a core circuit board; the core circuit board is communicated with a plurality of slave processors on a motherboard through a remote call technology, serial ports and network ports of the slave processors are mapped on the core circuit board; the core circuit board comprises a plurality of embedded processors, a Flash memory and a SRAM (static random access memory); the plurality of embedded processors are connected together by the serial ports, an assigned function of one of embedded processor is mapped onto another embedded processor by embedded RPC (remote procedure call) communication protocol; the plurality of slave processors are connected in a manner of multiprocessor interconnection, and the photovoltaic information acquisition device has the advantages of flexibility, easy expansion, easy transplantation, high safety and high efficiency.

Description

technical field [0001] The invention relates to an information collection device, in particular to a photovoltaic information collection device. Background technique [0002] Photovoltaic information collection devices are used for data collection of photovoltaic equipment such as inverters and combiner boxes in photovoltaic power plants. A photovoltaic information collection device usually needs to collect hundreds of photovoltaic devices through serial ports or downlink network ports, and then upload the data through the uplink network port. Upload to server. [0003] The current photovoltaic information collection devices mostly use a single embedded processor solution, and the hardware resources of industrial-grade embedded processors suitable for the photovoltaic industry are relatively poor (such as only a few serial ports and 1 network port), so the connected Photovoltaic installations are very limited. [0004] The way to solve resource shortage is generally to add...
