Abstract
The invention relates to an intelligent data protocol conversion method and apparatus. The invention provides a data protocol conversion method which employs an interconnection type ARM processor provided with a DSP module to carry out software conversion, and provides an intelligent data protocol conversion apparatus. The apparatus comprises a master control unit, an upper layer interface unit and a lower layer interface unit. The master control unit can perform data protocol conversion according to mode needs. When an upper layer interface conversion mode works, data protocols among upper layer interfaces can be rapidly converted, such as conversion of a USB to an RS-232, conversion of the USB to an Ethernet interface, and the like; when a lower layer interface conversion mode works, data protocols among lower layer interfaces can be converted rapidly, such as conversion of I2C to SPI, conversion of the SPI to a parallel interface, and the like; and when the upper layer interface conversion mode and the lower layer interface conversion mode work, protocols of the upper layer interfaces and the lower layer interfaces can be interchanged rapidly, such as conversion of the USB to the SPI, conversion of a serial port to the SPI, control over on-off of a relay by an Ethernet, and the like. The ARM chip in the master control unit is provided with the DSP module, can rapidly carry out data processing, and ensures a high rate and a low error rate of data protocol conversion.
