Problems solved by technology

In the current method, the server generally only receives and sends simple data to a single client, and does not involve the management of multi-client connections and the link of receiving control commands from the client; the client also only receives and sends simple data to the server, without involving the slave server. The terminal regularly receives a large amount of d

Abstract

The invention discloses an information interaction method, and belongs to the technical field of the data transmission. The method comprises the following steps: a server connects with a client through a data channel, and sends acquired data information to the client; the client connects with the server through a command channel and sends command information to the server. The data channel and thecommand channel are used for connecting the server and the client, the data channel is used for realizing the sending and receiving of the data information, and the command channel is used for realizing the receiving and the sending of the command information, a way for the information sending and receiving thread is reasonably designed so as to perform information interaction; the reliability and practicability of the method applied to the information interaction in the development process are guaranteed, and the real time and the controllability of the data transmission process are ensured.The method can be used for other the network interaction of non-Windows operation system in an extensible way, and capable of satisfying the data transmission demands of being large in data size, high in real time and complex in thread interaction of the distributed test system.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to an information interaction method and system. Background technique [0002] In the prior art, the front-end computer of the distributed test system is controlled by the back-end computer, implements data collection and processing, and sends the collected data to the back-end in real time; the back-end computer receives data through the network and sends control commands to the front-end computer to control Operations such as start, stop and information feedback of the front-end acquisition process. The front-end and back-end computer interaction information is diverse, and it is necessary to reasonably design information interaction methods to avoid unreliable factors such as untimely information transmission. At present, the test system network connection based on Windows operating system mainly adopts UDP (User Datagram Protocol) and TCP (Transmission Control...
