The utility model relates to an investigation of tourism industry chain data and monitoring system, include based on cloud processing data processing server, internet communication network, thing networking communication network, the data communication router, the data conversion device, thing networking controller, computer and terminal acquisition mechanism are controlled to data, wherein based on cloud processing data processing server respectively through internet communication network, thing networking communication network controls the computer with data and terminal acquisition mechanism is connected, data are controlled and are made up at least one sub - service network through internet communication network between the computer, found at least one subdata communication network through thing networking communication network between thing networking controller, terminal acquisition mechanism is a plurality of, and each terminal acquisition interagency is parallelly connected each other. This novel simple structure uses nimble aspect just, and system' s structure and operation expense are cheap, and data communication signal stabilization and security are good, and it is extensive to cover the face territory to good commonality and scalability have.
