Specifically, referring to fig. 1, the present application discloses an experimental intelligent scoring method, which may include steps S101-S106.
Step S101: and acquiring a video image acquired by an image acquisition device, and acquiring the image of the experimental area by the image acquisition device to obtain the video image of the experimental area.
In the step, the image acquisition device arranged above the physical electrical test bed is used for carrying out screen-viewing image acquisition on the operation behaviors of experimenters, and the acquired video images are sequentially uploaded to equipment applying the method through a network according to the acquired time nodes, wherein the position of the image acquisition device can be selected according to the requirements of users, and the image acquisition device is only required to carry out complete image acquisition on the operation area of the electrical test bed. For example, the image acquisition device may be disposed directly above the physical electrical test stand.

And then determining the time sequence of each wire interface of the operating equipment inserted into the wire plug based on the time node of each video frame in the acquired video image.
In this step, when it is recognized that the wire plug is inserted into the operation device, by recognizing the position thereof on the operation device, it is possible to determine the position of the wire interface of the operation device into which the wire plug is inserted, that is, which wire plug is connected to which wire interface of which operation device.
After a certain wire interface is inserted into the wire plug, the fact that the wire plug is inserted into the wire interface is always detected in a following video image, therefore, a timestamp corresponding to a video frame which is detected that the wire plug is inserted into the wire interface for the first time can be used as the time for inserting the wire plug into the wire interface, in this way, when an experiment is finished, the time node of each wire interface into the wire plug can be determined, and then the sequence of inserting each wire interface into the wire plug can be determined based on the time node of each wire interface.

In the scoring process, monitoring personnel are not required to participate, the objectivity and the uniformity of the scoring standard in the scoring process are ensured, and the automatic scoring of an operation experiment is realized.
In the technical scheme disclosed in another embodiment of the present application, it is considered that some experiment operators are difficult to complete the operation experiment due to insufficient knowledge storage, and cannot make the target operation equipment enter the preset state.
To this end, the method further comprises:
and when the video image acquired by the image acquisition device is acquired, timing is started, and when the timing duration reaches the set duration, if the working state of the target operation equipment still does not reach the preset state, the experiment is ended.
In this embodiment, when an experimenter starts an experiment, the image acquisition device is first turned on, after the image acquisition device is turned on, video image acquisition is performed on a monitored area, when the device applying the method acquires a video image acquired by the image acquisition device, it is indicated that the experiment starts, a timer starts to time, when the time length of the time length reaches a preset time length, it is determined that the working state of the target operating device still does not reach the preset state, it is indicated that the experimenter does not complete the experiment within a specified time, and the experiment is ended.
In the technical solution disclosed in the embodiment of the present application, in an experimental process, when connecting each wire interface, some wire interfaces may be associated interfaces, and a wiring sequence of the wire interfaces has a special rule, that is, a sequence of wiring of the associated interfaces is specified, and if the wiring sequence of the associated interfaces is wrong in the experimental process, a deduction is performed, so in this scheme, based on a preset wiring sequence, it is determined whether a time sequence in which each wire interface of the operating device is inserted into the wire plug is correct, including:
acquiring a preset wiring sequence, wherein a plurality of groups of insertion sequences are specified in the preset wiring sequence, each group of insertion sequences are insertion sequences of at least two preset wire interfaces which are associated with each other, for example, a wire interface A and a wire interface B are specified in the preset wiring sequence as associated interfaces, and in the experimental process, the wire interface A needs to be connected firstly, and then the wire interface B needs to be connected;
and when the experiment is finished, determining the time sequence of each wire interface inserted into the wire plug, and judging whether the time sequence of each wire interface of the operating equipment inserted into the wire plug is correct or not based on the preset wiring sequence. In this step, when it is monitored that a wire interface has a wire plug inserted based on a certain frame image in the acquired video images, the specific time when the wire interface is inserted into the wire plug can be determined based on the timestamp of the frame image, then the sequence of inserting each wire interface into the wire plug can be determined by sequencing according to the time, then the sequence of inserting each group of interrelated wire interfaces into the wire plug is extracted from the sequence, and the sequence is compared with the preset insertion sequence of the preset wire interface, so that whether the insertion sequence of an experimenter is correct or not can be determined.
When an experimenter connects a wire interface and a wire plug, after the wire plug is inserted into the wire interface, the wire interface may need to be inserted again or replaced for various reasons, at this time, the video image may detect that the same wire interface has wire plug insertion at multiple time points, and for this situation, the detected time when the wire interface is inserted into the wire plug for the last time may be used as the final time when the wire interface is inserted into the wire plug, and the sequence of inserting the wire plug into each wire interface may be sorted based on the final time when each wire interface is inserted into the wire plug. That is, the method may further include:
and when detecting that the same wire interface is inserted into the wire plug for multiple times based on the video image, taking the time node of the last time of inserting the wire plug into the time axis as the insertion time of the wire interface.
