Embodiment Construction

[0016] The core idea of ​​the present invention is: set up the non-IP data exchange channel between the data sender and the data receiver; The data sender sends data to the data receiver through the non-IP data exchange channel, after the data receiver receives the data, first Determine the data type, call the corresponding data processor for processing according to the data type, and return the processing result to the data sender after the processing is completed. The non-IP data exchange channel refers to a channel that is not based on the TCP / IP protocol for data exchange, and may use a USB data exchange channel or an ASI (Asynchronous Serial Interface, asynchronous serial interface) data exchange channel. Since the present invention does not perform data exchange through the TCP / IP protocol, the security of data exchange is improved.

[0017] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

Abstract

The invention discloses an asynchronous data exchange method and an asynchronous data exchange system, which belong to the technical field of data exchange. In the prior art, data transmission among computers or among computer networks is executed by a transmission control protocol / internet protocol (TCP / IP), the supported transmission format is relatively singular, and the security of file transmission is relatively low. In the method and the system of the invention, a non-IP data exchange channel is established between a data sender and a data receiver, the data sender sends data to the data receiver through the non-IP data exchange channel, and after receiving the data, the data receiver judges the type of the data, calls the corresponding data processor for processing according to the data type, and after the treatment, feeds a processing result back to the data sender. In the invention, the data is not exchanged by the TCP / IP, so that the security of the data exchange is improved.

Description

technical field [0001] The invention belongs to the technical field of data exchange, and in particular relates to an asynchronous data exchange method and system, which is especially suitable for the environment where a stand-alone system or a network system requires high security, but needs to be interconnected with other stand-alone systems or network systems. Background technique [0002] At this stage, the data exchange between the mainstream system levels is mostly based on the TCP / IP network protocol, such as HTTP protocol file upload and download, FTP protocol file transfer, etc. For the above data transmission methods, the supported transmission format is relatively simple, and the security for data transmission is poor. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide an asynchronous data exchange method and system, which can improve the security of data transmission. [0004] In order ...
