The present invention provides a management and control system and method for the Internet of Things, which solves the problems of complex construction process, high technical requirements for personnel, high labor intensity, high cost, high dependence on customization, poor flexibility, poor stability, and self-healing performance of the existing industrial Internet of Things system. Insufficient problem, in this solution, the transmitter, controller and multi-function gateway device at the sensor network end can freely form a network, the transmitter collects and encapsulates data, and transmits the encapsulated data packets to the control controller, the controller transmits the data packet to the IoT processing platform through the multi-functional gateway device for parsing, preprocessing, storage, and display. Among them, the data and variables are intelligently associated before the IoT processing platform displays, reducing the Errors caused by human operations, using the above-mentioned technical solutions in this application, avoid the problems of complex construction process, high technical requirements for personnel, high cost, poor flexibility, poor stability, and insufficient self-healing ability of the existing industrial Internet of Things system.
