The invention discloses an intelligent Internet of things data exchange platform scheme based on a hardware electromechanical field. The intelligent Internet of things data exchange platform scheme consists of an infrastructure layer, a data layer, a service component layer, a service layer and an application layer. Products and substances in the hardware electromechanical field are connected with an Internet of things through information sensing equipment, such as radio frequency identification, an infrared sensor, a global positioning system and a laser scanner, according to a pre-appointed protocol on the basis of a computer Internet and wireless data communication, so that product information and substance information are exchanged and communicate with each other to form a network which covers different products and different substances in the hardware electromechanical field and is used for performing intelligent identification, positioning, tracking, monitoring, management and stock counting; instant sharing conversation is realized, and uniform management is facilitated; therefore, hardware electrochemical production enterprises and merchants in the platform can accurately master the stock and the production information and the substance information during production and circulation; stock of the products is effectively reduced, and fund overstock is reduced; and the aim of zero stock is fulfilled.
