The invention relates to a router for transmitting information among a plurality of communication protocols. A central processor is connected with a memory for bilateral communication; the central processor is connected with a wired outward data exchange module for bilateral communication; the central processor is connected with a wireless outward data exchange module for bilateral communication; the wireless outward data exchange module is connected with an antenna array for bilateral communication; and a power supply is electrically connected with the central processor, the memory, the wired outward data exchange module and the wireless outward data exchange module respectively. Through use of an embedded main MCU (Microprogrammed Control Unit), various communication chips and a high-capacity non-volatile memory, a user can perform data exchange with other product equipment conveniently in real time, perform control on other product equipment, and get expert advice for data analysis from a cloud system, and data can be stored and analyzed for use as long-term data of a specific or non-specific user. The router is simple in structure, convenient to use, and low in price.
