Abstract:At present ,there are many gaps in the support characteristics of the naval shore defense weapon system .Aiming at how to objectively and accurately evaluate the characteristics of equipment support ,grasp the equipment technology in time ,and timely develop equipment suppot,and quickly from the support capability.Amethod for evaluating support characteristics by using state monitoring technology is proposed.Using state monitoring technology to acquire and grasp the technical state of target objects,respond to various security needs quickly and accurately .Timely and actively optimize the equipment performance ,give full play to the operational effectiveness of the shore defense weapon system, and provide theoretical and method support for the scientific and accurate evaluation of the equipment support characteristics.Lay the foundation for the transformation of post based maintenance and preventive maintenance to state based repair mode.
