The implementation principle of one implementation mode in the embodiment of the application is as follows:
because the target identification test paper can show an identification result after a certain period of time, when the target identification test paper is placed in the target test paper placing area, the target electromagnet corresponding to the target number is switched to be in an electrified state according to the target number of the target test paper placing area, so that the target electromagnet generates magnetism to adsorb the target identification test paper, and the possibility that the target identification test paper is displaced on the rectangular operating platform due to objective factors is reduced.
In one implementation manner of the embodiment of the present application, referring to fig. 6, the step S105 of obtaining the identification result of the target identification test paper specifically includes the following steps:
s601, recording the electrifying time of the target electromagnet.
When the target electromagnet corresponding to the target number is switched to the energized state, the energization time of the target electromagnet starts to be recorded, so that the energization time can also be used as the identification time of the target identification test paper.
S602, judging whether the electrifying time exceeds a preset electrifying time threshold value or not at intervals of a preset interval time, and if the electrifying time exceeds the preset electrifying time threshold value, executing the step S603; if the energization time does not exceed the energization time threshold, step S604 is executed.
The power-on time threshold value can be preset according to the average identification time of the target identification test paper under a normal condition.
And S603, sending a voice prompt to prompt the test paper appraiser to appraise the test paper again.
A preset fourth voice prompt is sent out through a loudspeaker, and step S103 is executed again, where the specific content of the preset fourth voice prompt is "test failure, please use the spare test paper to perform test paper identification again".
S604, judging whether an identification mark position appears in the target identification test paper, and if the identification mark position appears in the target identification test paper, executing the step S605; if the identification mark does not appear in the target identification test paper, step S606 is executed.
The identification mark comprises a comparison identification mark and a result identification mark, the surface of the target identification test paper is provided with a T-marked strip-shaped recess and a C-marked strip-shaped recess, the C-marked strip-shaped recess is the comparison identification mark, and when the C-marked strip-shaped recess changes in color, the identification of the target identification test paper is successful. The target identification test paper will show the identification result through the color change appearing in the two elongated recesses. Therefore, whether the color change of the strip-shaped concave slot marked with the C in the target identification test paper occurs or not can be judged through an image recognition technology, and if the color change of the strip-shaped concave slot marked with the C occurs, the judgment result is that the identification mark position occurs in the target identification test paper.
And S605, generating an identification result of the target identification test paper based on the identification mark.
The color change condition of the T-marked strip-shaped recess determines the identification result of the target identification test paper, and if the T-marked strip-shaped recess has color change, the identification result is a positive identification result; if the color of the strip-shaped concave slot marked with the T does not change, the identification result is a negative identification result.
S606, continuously judging whether the power-on time exceeds a preset power-on time threshold value.
Wherein step S602 is continued.
The implementation principle of one implementation mode in the embodiment of the application is as follows:
the identification marker in the target identification test paper can be identified through an image identification technology, when the color change of the contrast identification marker in the target identification test paper is identified, the target identification test paper is identified successfully, and whether the color change of the result identification marker in the target identification test paper occurs or not can be further judged to obtain the identification result of the target identification test paper. When the power-on time of the target electromagnet, namely the identification time of the target identification test paper exceeds a preset time threshold, the identification mark position of the target identification test paper is still not identified, which indicates that the identification of the target identification test paper may be abnormal due to the operation error of a test paper identifier, so that a voice prompt needs to be sent to prompt the test paper identifier to identify the test paper again.
In one implementation manner of the embodiment of the present application, the identification result includes a positive identification result and a negative identification result, and referring to fig. 7, the uploading the identification result and the real-time location information to the management platform in step S106 specifically includes the following steps:
s701, judging whether the identification result is a positive identification result or a negative identification result, and if the identification result is the positive identification result, executing a step S702; if the result of the identification is a negative identification result, step S705 is performed.
S702, storing the identification video of the test paper identification area.
The video time period for identifying the video is from the time when the target identifier is successfully authenticated to the time when the human face image and the test paper identification area are judged to be abnormal.
And S703, integrating the identification video, the real-time position information and the identity information into alarm information, and uploading the alarm information to a management platform to enable the management platform to send out an alarm.
And S704, storing the identification video to a video database preset in the management platform.
And S705, integrating the identification result, the real-time position information and the identity information into identification qualified information.
And S706, uploading the qualified identification information to a management platform.
