Abstract: Disclosed are a module assembly and a multi-master communication method thereof, and more particularly, a module assembly including a plurality of modules capable of transmitting/receiving data by forming an open drain based one-wire communication bus upon mutual combination, in which at least one module requiring the data transmission among the plurality of modules performs first declaration for a transmission intention by outputting a low signal within a predetermined first arbitration time when at least one module is in an on state by sensing the one-wire communication bus state, at least one module performing the first declaration for the transmission intention performs second declaration for the transmission intention by outputting a high signal within a second arbitration time, and a module which outputs the high signal last within the second arbitration time secures final bus occupation.

Abstract: Disclosed are an assembly information providing system and a module assembly including a module assembly including at least one control module including a functional unit including an assembly information management unit generating assembly information; and a user terminal and an assembly information providing server connected to the module assembly through a network and an assembly information providing method including: receiving, by the user terminal or the assembly information providing server, the assembly information from the control module; and storing, by the user terminal or the assembly information providing server, the assembly information and determining whether an assembly error of the module assembly occurs based on the assembly information and transmitting assembly error information to the module assembly, and the assembly error information includes module unique information of at least one module with an error.
