Abstract:The concept, intelligence rating, and evaluation of smart airfield in airport are interpreted and proposed in this paper. The vision of smart airfield is clarified as “full-time safety, zero delay, maximal benefit, environment protection”. The definition of smart airfield in airport is proposed based on the elements of smart organism. Smart airfield is defined as an airfield composed of advanced infrastructure, service facility, monitoring network, data center, communication network and energy supply system, which has the ability of self-monitoring, automatic analyzing, self-adaptation, self-operation, information interacting, and continuous energy supplying. Based on the definition, the particular conception and logical relationship of smart abilities are given. Besides, the requirements of intelligence rating and evaluation system of smart airfield are proposed from two dimensions.
