Problems solved by technology

[0004] Although the single-link centralized data communication architecture has existed and been applied for a long time, in different single-link centralized data communication systems, the number of lower computers is different, and the data transmission rate between the upper computer and the lower computer , The response delay is different, so that when debugging different types of systems, it is always necessary to go through complex testing and analysis be

Abstract

The invention discloses an optimal time sequence control method and system for centralized data communication, and the method comprises the steps: calculating a work region where a lower computer carries out the interruption, and transmitting a message with a preset data length to the upper computer after the delay of a preset time if the work region is not at the lower computer end; at the uppercomputer end, when the length of the message returned by the lower computer is equal to the preset length and no bit error exists, unpacking the message packet count Mcn in the message, and determining the loss number of the message packet based on the unpacked message packet count Mcn and the last acquired message packet count M'cn; adopting a Monte Carlo simulation method, and based on preset system parameters, determining the loss number of message packets corresponding to each time interval of instruction sending of the upper computer and the corresponding loss rate; and determining one ofthe message packet loss rates with the minimum time interval smaller than the preset message packet loss rate threshold as the configuration value of the optimal time sequence. According to the method, the optimal time sequence control with the collision probability being zero or approaching zero can be found out.

Description

technical field [0001] The present invention relates to the technical field of Chinese data communication, in particular to an optimal sequence control method and system for centralized data communication. Background technique [0002] The centralized data communication architecture is derived from the client / server (C / S) mode in the computer network, and it is widely used in various fields such as industrial control buses. In the centralized data communication architecture, the client is generally called the lower computer, and the server is called the upper computer. There can be multiple lower computers and only one upper computer, which is used to centrally process all data information transmitted by all lower computers; according to The number of data communication links between the lower computer and the upper computer can be divided into single-link centralized and multi-link centralized. Among them, there is only one single-link centralized communication link, that i...
