Abstract

The invention discloses a data interaction method and device for an upper computer and a lower computer, equipment and a medium, and is applied to industrial equipment comprising the upper computer and the lower computer, when the upper computer receives a control request, program decomposition is carried out on an application program corresponding to the control request through a multi-channel mode, and each decomposed subprogram is obtained; the upper computer performs task decomposition on each subprogram based on a multi-thread control mechanism to obtain each decomposed subthread; and the upper computer performs multi-stage buffering on each sub-thread to obtain each piece of target buffering data, and transmits each piece of target buffering data to the lower computer, so that the lower computer controls a corresponding execution mechanism to operate according to each piece of target buffering data. The data interaction between the upper computer and the lower computer is carried out in a multi-channel, multi-thread and multi-level buffering data processing mode, so that the upper computer and the lower computer can quickly finish accurate reading and writing of the data during data interaction, and the efficiency of data interaction between the upper computer and the lower computer is improved.

Description

technical field [0001] The present application relates to the technical field of industrial automation, in particular to a method, device, equipment and medium for data interaction between upper and lower computers. Background technique [0002] At present, when the motion control based on PCI (Peripheral Component Interconnect, peripheral component interconnection standard) performs data interactive communication between the upper and lower computers of the board card, it adopts a single-channel, single-thread interactive mode to directly read and write data. When reading and writing data, it is easy to cause the application program to be occupied and wait for resources in the process of multi-threaded call control request and logic control, which makes it easy to read and write lags and errors between the upper and lower computers, resulting in low data transmission rate. , which in turn leads to low efficiency when the upper and lower computers perform data interaction. ...
