A real-time substation monitoring system is developed on the basis of the embedded system and wireless communication technology. The general system scheme and hardware/software design is introduced in detail.Online monitoring of partial discharge of switch cabinets and substation indoor environment is realized.Based on Cortex-A9 framework and Linux operating system and adopting QT and SQLite development utility program,the station monitoring host has such functions as onsite data management,query and alarm. The system communication adopts ZigBee and GPRS technology to solve problems of difficult wiring and high cost for existing substations.Research and experiment shows that the system is characterized by its high stability and reliability,flexible expansion, easy operation and installation,and has a broad application prospect.
