Description
Technical field
The invention belongs to computer communication field, stored by particularly relating on a kind of data transmission method and a data storage medium, data transmission software is to perform the method.
Background technology
In modern computer and information flourishing epoch, in order to effectively use information, first various data are done various process computing in main frame or server, then treated data are transmitted mutually in a wired or wireless fashion between main frame or server, to reach designed function.
At present, between embedded equipment (such as: touch man-machine interface) and computing machine, universal serial bus (USB:UniversalSerialBus) is often used to carry out data transmission.This kind transmits the mode of usually carrying out by: embedded equipment and receives the data the data of load operating or the transmission of data transmission software reception embedded equipment display data content that data transmission software transmitted.
Generally speaking, use USB to carry out data transmission and can have following four kinds: control type transmission (ControlTransfer), flood tide type transmission (BulkTransfer), interrupt-type transmission (InterruptTransfer), and wait time type transmit (IsochronousTransfer).Between human-computer interface device and computing machine, carry out USB transmission use two kinds of prior aries at present:
1.USB control type transmission (ControlTransfer), transmitting procedure is decomposed into multiple job step by it, makes human-computer interface device and data transmission software sequentially can perform the work of each transmitting step according to instruction in transmitting procedure.
2.USB flood tide type transmission (BulkTransfer), uses the USBhost of human-computer interface device.When sending the data of computing machine to human-computer interface device, first data must be changed into archives form, then USB Portable disk being inserted the USBhost of computing machine, then data is write USB Portable disk by service data transmission software.Subsequently Portable disk is removed from computing machine, then USB Portable disk is inserted the USBhost of human-computer interface device.The command interface of operation human-computer interface device, makes it load USB Portable disk data.Anti-, when sending human-computer interface device data to computing machine, data are write USB Portable disk by human-computer interface device, and data transmission software reads data from USB Portable disk again, and loads in computing machine.
The shortcoming of prior art 1 is, use control type transmission to need to support that various computer operating system writes this special USB driver to it, such as winXP, win7, win8 respectively need to write corresponding driver.Research and develop manpower and equipment limited when, be difficult to guarantee the compatibility of USB driver on different computer system platform and stability.Upgrade when computer operating system or often need when changing further again to write USB driver.Therefore, notifying that user downloads and further its data transmission software new from again writing USB driver to operation end, expending quite a lot of time and manpower.
In prior art 2, although different computer operating systems can support USB Portable disk, USB driver need not be write for respective operating system, but its shortcoming is the action of USB Portable disk plug to bring inconvenience to user, and easily download or upload function because wrong plug causes reaching data.For embedded equipment, user uses USB transmission line to reach data transmission usually.
Due to the more above-mentioned problem existed in actual conditions, and the product also do not addressed these problems at present or method occur, therefore truly have the necessity made improvements.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide data transmission software stored on a kind of data transmission method and a data storage medium to perform the method, to avoid prior art embedded equipment (i.e. human-computer interface device) and the disappearance that data between computer operating system are transmitted and shortcoming: different USB driver must be write for different computer operating system; Data cannot effectively be downloaded or upload by USB Portable disk plug inconvenience easily wrong plug.
