The utility model discloses a data transmission remote control system based on a double-port RAM, which comprises a PowerPC processor and a second microprocessor. A first microprocessor, the second microprocessor and the PowerPC processor are connected with each other via a PCI bus interface, the second microprocessor is connected with a remote control module of a host computer via a CAN bus, and the double-port RAM is connected between the first/second microprocessor and the PCI bus interface. According to the utility model, division of different processors is clear, processing is fast, and processing capability is strong, thereby solving the problem that processing capability of a single processor is insufficient, realizing data exchange among multiple processors via PCI buses, and greatly improving processing capability and transmission speed among the processors.
