The present invention discloses a coordinated control system and a coordinated control method of smart home equipment, and relates to control systems and methods of equipment in a smart home system based on the internet of things. The system comprises a local area network, the internet of things and a gateway connecting the local area network and the internet of things. The method comprises a linkage message configuration step and a linkage operation step. The linkage message configuration step can freely set linked equipment, linkage scenes or scene modules. The linkage operation step is that main nodes send operation commands through a broadcasting method while slave nodes complete operation of main equipment linking slave equipment. The linkage operation step also can match operation of all linkage lists one by one for the main nodes and send the operation commands, and the slave nodes carry out linkage operation by a communication response means. The problems of complicated operation, equipment crosstalk and high cost in linkage control of a smart home system are solved, and the coordinated control system which is simple to operate, free of equipment crosstalk and low in cost, and the corresponding control method are provided.
