Abstract: The communication protocols of different coal mine monitoring systems correspond to different data structures, which makes it difficult to configure and manage device information when multiple coal mine monitoring systems are integrated. To solve the above problems, an object-oriented device modeling method is proposed. The method converts a variety of non-standardized data structures into standardized data structures through data driving, and establishes corresponding device models based on the relevant attributes of actual devices. The method creates device instances based on device model, uses hierarchical tree structure to display the parent-child relationship of device instances, and displays the detailed information of device instances through dynamic pages, which enables unified configuration and management of devices with different attributes. The object-oriented device modeling method is applied to the graphic configuration so as to bind the device model to the graphic element and bind the device instance to the graphic instance, which can quickly configure the data visualization graphics.
