The invention discloses a platform development method for a lightweight low-voltage protection device. The method is based on a lightweight hardware platform and a system software architecture, flexible combination of service modules is carried out according to a device configuration text, initialization and starting of the service modules are controlled by a management module, each service module runs according to a preset priority, Efficient data interaction is completed among the modules through a shared memory, and coexistence of real-time services such as protection logic processing and non-real-time services such as a man-machine interface is achieved. According to the method, on the basis of a lightweight software and hardware architecture and a highly reusable service module, platform development of the low-voltage protection device is achieved.
Description
technical field [0001] The invention relates to the field of power system control and protection, in particular to a platform-based development method for a light-weight low-voltage protection device. Background technique [0002] Power system high-voltage control and protection devices generally adopt a multi-board distributed parallel processing software and hardware architecture because of their high reliability requirements, complex protection functions, large amount of protection calculations, numerous communication protocols, rich external interfaces, and strong scalability. Usually special DSP boards are used to run real-time services, such as control and protection logic calculation, and the software generally adopts no operating system architecture; special management boards are configured to run non-real-time services, such as human-computer interaction, external communication, fault recording, etc. High-performance processors, running embedded Linux and other oper...
