Communication system for transmitting simulation data

Abstract

The invention relates to a communication system for transmitting simulation data, which comprises a plurality of clients and a server. The server comprises a monitoring module, a data state recognition module, a non-state-data receiving module, a sate data receiving module, a communication sub-process module and a simulation service processing module. The clients transmit data to the server, the server transmits the received data to the monitoring module and the monitoring module detects the data; if the clients are valid clients, the data are transmitted to the data state recognition module;otherwise, the data are returned back to the clients; the data state recognition module analyzes the data, if the data are non-state-data, the data are transmitted to a shared data exchange area through the non-state-data receiving module; and if the data are state data, the communication sub-process module is enabled through the state data receiving module, the data are processed in the simulation service processing module, a processing result is transmitted to the shared data exchange area and a simulation result is transmitted to the clients through a communication sub-process. The communication system for transmitting the simulation data can be widely used in the communication system for simulation data transmission in the test control field.

Description

technical field [0001] The invention relates to a communication system, in particular to a communication system suitable for transmitting simulation data in a measurement and control system. Background technique [0002] The communication system in the field of measurement and control is different from the communication system of ordinary LAN or WAN. First, the client in the field of measurement and control is predictable and controllable. Secondly, the communication system in the field of measurement and control has certain requirements for real-time performance, especially the amount of data. The transmission of relatively small measurement and control data, such as temperature, pressure, flow and other data, generally has higher requirements for response speed. With the continuous development of the measurement and control field, the functions realized by the measurement and control system are becoming stronger and stronger. In order to improve the reliability of the meas...

Problems solved by technology

Processing simulation commands has the nature of exclusive resources and consumes more resources, and it is necessary to avoid interference of the simulation process by other processes, especially when each client process uses computing service resources

When there is a transient line failure in the communication system, the client may not be able to request the simulation service again, because the client’s identity has been recorded at this time. Due to the characteristics of each client’s single process using computing service resources, the server may think that the same client is performing The second request is made, thereby rejecting the client's request, and the server may also be waiting for the client to receive the response of the simulation data. The client has entered an infinite waiting state and cannot communicate with the server.
