According to the requirements of equipment combat application and intelligent support development, a construction method of intelligent network for equipment support is proposed. According to the characteristics of equipment data, the equipment data system model is established, and the support knowledge construction and reasoning method based on the mapping relationship between data tag attributes and knowledge ontology elements is given, and the equipment support intelligent network construction based on data and knowledge hybrid drive is completed. Taking the vehicle equipment support intelligent network construction as an example, the construction process is analyzed. The results show that this method can provide important support for the realization of intelligent and precise equipment support and the improvement of actual combat capability of equipment.
