Abstract: Industrial internet identifier resolution is the nerve center supporting the interconnection and intercommunication of manufacturing resources, production processes and intelligent products in instrument industry, and is the premise and foundation for achieving accurate docking of global supply chain systems and the different enterprise production systems, and the product lifecycle management and the intelligent service of instrument enterprises. At present, many enterprises in the instrumentation industry have the applied identifier resolution in product development, production, supply chain, sales, service and other links, but the industrial chain has not been got through, coding rules have not been united, and information islands still exist.Aiming at the characteristics of instrument industry, such as multi-variety, small batch, wide application, fast updating and high-tech sensitivity, this paper puts forward the application path of industrial internet identifier resolution for instrument industry, gives the construction scheme of secondary node, enterprise node and application service platform for instrument industry, and finally verifies the innovative application of the industrial internet identifier resolution in instrument industry basedon typical applicationcase analysis.

Key words: industrial internet identifier resolution, instrument industry, innovative applications, application service platform
