Abstract

The invention provides a multipath serial port expansion and data unvarnished transmission processing method and system.The method comprises the steps that a multipath serial port expansion device is designed and used, and the multipath serial port expansion device comprises an integrated serial port, a sub-serial port, a single-chip microcomputer and a power module; the single chip microcomputer comprises an integrated serial port module of the single chip microcomputer and a serial port expansion chip which is externally connected through an SPI (Serial Peripheral Interface); data packaging is realized on the basis that frame headers, channels, byte lengths and check fields are added into multi-channel serial port data, and data of at least 64 sub-serial ports are sent to a computer end through the integrated serial port module; and the computer end analyzes the received multi-path serial port data through a transparent transmission data analysis method for matching a frame header and a verification field, and processes invalid data. According to the technical scheme, the expansion capacity of the serial port number is greatly improved, the limitation of an existing computer on serial port number recognition is broken through, and the requirement for multi-device access is met.
