To achieve the deep informationization in ginger industry chain, an information perception system was built based on the internet of things. By making full use of the concepts and methods of thorough perception, some information collection terminals were designed for different stages of ginger industry chain, such as planting stage perceived terminal, warehousing stage perceived terminal, processing stage perceived terminal, cold chain transport stage and sales stage perceived terminal, etc. And the information of the ginger industry chain was acquired automatically with these terminals. In order to achieve real-time query and information submission, a general information collection instrument for ginger industry chain was developed. Moreover, an industrial chain information management platform was developed with J2EE architecture, which could be managed effectively.
