the acquisition module is used for acquiring the basic information of the source terminal controller stored in the local controller;
the analysis module is used for requesting a local controller to register the configured reference points belonging to the source end controller according to the basic information and analyzing a data response message returned by the source end controller; after the analysis is finished, storing the data information of the reference point and the analysis result into the inter-controller data interaction queue corresponding to the reference point, and updating the corresponding mark bit of the reference point;
the operation module is used for loading the reference points in the corresponding inter-controller data interaction queues to corresponding positions in the algorithm page to participate in operation, and clearing the updated mark bits of the reference points after the operation is finished;
the basic information comprises the number of reference points of the source end controller, the IP address of the source end controller, the network link state of the source end controller and a configuration change mark in the source end controller; judging the reference point number, the network link state and the configuration change mark of the source end controller;
the judging the reference point number, the network link state and the configuration change mark of the source end controller specifically comprises the following steps:
if the number of the reference points of the source-side controller is 0, the local controller starts to traverse the next source-side controller;
if the network link states of the source-end controller are all bad, traversing the reference points belonging to the source-end controller in the inter-controller reference point queue stored in the local controller, acquiring the update marks of the reference points according to the algorithm page numbers of the reference points stored in the inter-controller reference point queue in the local controller and the data offsets of the reference points in the algorithm page data area, and judging the values:
if the updating mark of the reference point is 1 and the information of the reference point does not need to be updated, skipping the reference point and traversing the next reference point belonging to the source-end controller in the reference point queue between the controllers;
if the update mark of the reference point is 0, setting the quality of the reference point as bad in the interaction period, pressing the quality of the reference point into a data interaction queue between controllers corresponding to the algorithm task period, setting the update mark of the reference point as 1, and waiting for the algorithm task loading in the subsequent algorithm task period;
if the link state of the source end controller is good, requesting the source end controller to register the configured reference point belonging to the source end controller in the local controller;
if the configuration change mark of the source-side controller is 1, the configuration updating operation is carried out in the source-side controller, the local controller sends a request to the source-side controller again, the content of the request is data offset information of all reference points belonging to the source-side controller in the reference point queue between the controllers in the algorithm page data area in the source-side controller, after the data offset information is obtained, new data offset information is pressed into the data interaction queue between the controllers of the reference points in the algorithm task period corresponding to the local controller, and the updating mark of the reference points is set to 1.
7. An electronic device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, the processor implementing the steps of the multitask cycle oriented data interaction method according to any of claims 1-6 when executing the computer program.
8. A computer-readable storage medium, having stored thereon a computer program which, when being executed by a processor, carries out the steps of the multitask cycle oriented data interaction method according to any one of the claims 1-6.
