Research on the Remote Monitoring System of Photovoltaic Power Station Based on CAN Bus and GPRS with Mechanical Properties

摘要

According to the requirements of the PV station remote monitoring system, such as big information flow, far distance transmission, high-performance, this article has designed a remote PV station monitoring system based on CAN bus and GPRS with mechanical properties. After lucubrated CAN bus and GPRS communication technology, this article details the hardware circuit of the slave computer, the communication protocol of CAN bus and the design of communication network. It has solved the problems that bad real-time, low degree of automation, few nodes can be accommodated, weak anti-interference ability which exits in the past design of PV station remote monitoring system.
