Problems solved by technology

This service does not guarantee the reliability of data transmission. Data may be lost or duplicated during transmission, and data cannot be guaranteed to be received in sequence. Therefore, data transmission is not reliable, and data transmission between devices is also unreliable. There is no reliability, so it is impossible to guarantee whether the data sent by the client to the server is received or whether it is received correctly

Abstract

The embodiment of the invention provides a socket communication method and apparatus based on TCP / IP and an analog visual simulation system, and belongs to the field of data communication. The method comprises the following steps: obtaining a simulation server socket library by a simulation server, and creating simulation server sockets according to the simulation server socket library; binding the created simulation server sockets on the local IP address and a local port; setting the simulation server sockets as a monitoring mode, and waiting for a connection request sent by a virtual image display device; receiving the connection request sent by the virtual image display device, and sending the sockets corresponding to the connection request to the virtual image display device according to the connection request; and performing communication with the virtual image display device according to the sockets corresponding to the connection request. Therefore a reliable communication connection can be established through the sockets to improve the reliability and accuracy of the data communication between the virtual image display device and the simulation server.
