Intelligent looped network box transformer measurement and control device employing FPGA simulation switcher chip

Abstract

The invention discloses an intelligent looped network box transformer measurement and control device employing an FPGA simulation switcher chip, and the device comprises a management CPU, a communication CPU, a CAN bus, a PNL liquid crystal panel, a remote server, and a Beidou / GPS terminal. The management CPU is electrically connected with the PNL liquid crystal panel, the Beidou / GPS terminal and the CAN bus. The management CPU is connected with the communication CPU through an Ethernet network, and is connected with the remote server through a plurality of Ethernet networks. The CAN bus is externally connected with a switching-on power insertion part, a switching-on / switching-off module, a resistor temperature detector switching-on and switching-off module, and an AC switching-on and switching-off insertion part. The communication CPU is externally connected with ten main station RS485 series wiring terminals, two optical fiber Ethernet networks, two SFPs, and a ZigBee module. The device employs a double-CPU design and the plug-and-play technology, can quickly achieve the intelligent measurement and control and communication management, can achieve the analog collection of high-voltage side and low-voltage side, non-electric quantity protection, remote control and communication of a box transformer and a looped network switcher function.

Description

technical field [0001] The invention relates to an intelligent ring net box substation measurement and control device using an FPGA analog switch chip, and belongs to the technical field of photovoltaic station measurement and control devices. Background technique [0002] Since 2000, photovoltaic has been the core of the country's new energy development, because photovoltaic power generation has the characteristics of: no risk of exhaustion, safe and reliable, no noise, no pollution emissions, and absolutely clean (no pollution). Therefore, it also plays a very important role in the country's strategic route of "promoting energy conservation, emission reduction and low-carbon development", and is an industry that the country focuses on investment and development. With the construction and development of domestic photovoltaic stations, photovoltaic station products and on-site solutions will also become a new output business with stable profits for various equipment manufact...
