Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Currently, new technologies are presented for debugging the sequential control function of an intelligent substation monitoring host, wherein the method disclosed in domestic patent application (CN 110568284A/201910767351.8) is the most representative (as shown in figure 2). The scheme provides a one-key sequential control automatic test verification method, which is implemented by receiving a sequential control request sent by a monitoring host; driving the simulated intelligent device control service to respond to the sequential control request according to the preconfigured intelligent device sequential control logic; sequential control logic for collecting response data obtained by the monitoring host; and comparing the sequence control logic of the response data with the sequence control logic of the configured intelligent equipment to obtain a test result.
However, the applicant has found that there are 4 problems with this solution.
