Driving assembly management system, fault detection method, and electric power-assisted bicycle

A driving assembly management system, comprising:

• an Internet-of-things device, multiple digital assemblies and a bus;
• each digital assembly comprises:
• one driving assembly in a driving system of an electric power-assisted bicycle, and a digital circuit connected to the driving assembly, wherein the digital circuit comprises:
• an assembly signal processing circuit, a first processor and a first memory, wherein an input end of the assembly signal processing circuit is connected to a signal collection end of the driving assembly, so as to process a driving signal of the driving assembly during working, and obtain working state data of the digital assembly;
• the first processor is further connected to the assembly signal processing circuit, so as to acquire the working state data of the digital assembly;
• and the first memory is connected to the first processor, so as to store the working state data and identification information about the digital assembly;
• and
• the Internet-of-things device is connected in communication with the first processors in the multiple digital assemblies through the bus, so as to perform fault detection according to the working state data of the multiple digital assemblies and the identification information about the multiple digital assemblies.
