Design of software structure for a novel pole mounted switch controller based on embedded Linux

A novel design of pole mounted switch controller is introduced in this paper, embedded Linux operating system was used to enrich the functions of the pole mounted controller and to enhance the intelligence of the controller. Software structure of this novel designed controller is presented in detail. Multiple processes design method was applied to split the software application into 3 processes, namely user interface, communication and fault treatment. Socket communication was re-designed and a shared memory method was adopted to realize interprocess communication.
