Through the course learning and competition training of switching operation, students are mainly trained to be able to perform power outage operations of electrical equipment according to the switching operation specifications and safety operation requirements, providing necessary support for the employment needs of operation and maintenance positions in power transmission and distribution enterprises.

[0003] However, during the class and acceptance process, the switching operation assessment is a relatively time-consuming learning outcome evaluation. The teacher's assessment time for a group is relatively long, and because the class has a large number of students, while one group is being assessed, other groups are waiting for the exam. Therefore, the assessment efficiency is not high, and there is a serious waste of time. At present, there is no special switching operation assessment system on the market to assist teachers in completing the switching operation assessment, so as to improve the efficiency of the switching operation assessment.

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Embodiment 1

[0021] To solve the problems of slow efficiency of intelligent switching operation evaluation, such as Figure 1 As shown, the present invention provides an intelligent switching operation evaluation method, characterized in that it comprises the steps of: S1, obtain the assessment code through the human-computer interaction module A1, and obtain the assessment process according to the assessment code; S2, initialize the intelligent switching operation evaluation process through the central processor M1, and load the corresponding correct operation evaluation process into the central processor M1 according to the evaluation process; S3. According to the correct operation evaluation process, determine whether the state confirmation module A2 and the switch separation module A3 are in a closed state during the operation. When the switch separation module A3 is in a closed state, determine whether the current operation is correct according to the closed state of the state confirmation module A2, and perform corresponding processing operations through the central processing unit M1 according to the judgment result; S4. According to the correct operation evaluation process, determine whether there is an obstruction blocking the detection module A4 that changes the conduction state based on light conduction during the operation, and perform corresponding processing operations through the central processing unit M1 according to the judgment result.

[0022] According to the needs of the examinee or the teacher, the assessment content code of the switching operation is selected and confirmed. When the examinee confirms the test, the assessment code is obtained through the human-computer interaction module A1, and the assessment process is obtained according to the assessment code. Then, the intelligent switching operation assessment process is initialized through the central processor M1, and the corresponding correct operation assessment process is loaded into the central processor M1 according to the assessment process. According to the correct operation assessment process, it is judged whether the state confirmation module A2 and the switch separation module A3 are in the closed state during the operation. When the switch separation module A3 is in the closed state, it is judged whether the current operation is correct according to the closed state of the state confirmation module A2. When the switch separation module A3 is in the closed state, if the state confirmation module A2 is in the open state, the current operation is an erroneous operation; when the switch separation module A3 is in the closed state, if the state confirmation module A2 is in the closed state, the current operation is a correct operation; but when the switch separation module A3 is in the open state, the current operation is an erroneous operation; according to the correct operation evaluation process, it is judged whether there is an obstruction blocking the detection module A4 that changes the conduction state based on light conduction during the operation, and the central processor M1 performs corresponding processing operations according to the judgment result; wherein, the detection module A4 is provided with a first light emitting diode DS1 and the second photosensitive diode DS2 arranged opposite to it detect the obstruction through the first light-emitting diode DS1. When there is an obstruction, the first light-emitting diode DS1 and the second photosensitive diode DS2 are in a conductive state and output an analog signal to the central processing unit M1. The central processing unit M1 outputs a control signal to the voice control unit to perform an error alarm operation, prompting the candidate that this step is wrong, and the assessment is directly stopped due to the illegal operation, and no points can be scored and the assessment cannot be continued; when there is no obstruction, the first light-emitting diode DS1 and the second photosensitive diode DS2 are in a non-conductive state, and the ... central processing unit M1 outputs a control signal to the voice control unit to perform an error alarm operation, prompting the candidate that this step is wrong, and the assessment is directly stopped due to the illegal operation, and no points can be scored and the assessment cannot be continued; when there is no obstruction, the first light-emitting diode DS1 and the second photosensitive diode DS2 are in a non-conductive state, and the central processing unit The processor M1 outputs a high level to the indicator light to light up the operation. Since the assessment process is complicated and the needs of each candidate are different, the correct assessment process is judged according to different procedures. Each time a step is correct, the corresponding switch separation and combination module A3 will be closed, and the corresponding indicator light will be turned on. Since some steps do not require operation, only inspection is required, but after each step, the candidate is required to confirm his or her own operation steps. After the candidate completes the inspection, the status confirmation module A2 is closed and the corresponding indicator light is turned on. The correct score of the candidate's switching operation is confirmed according to the number of turned-on indicator lights, thereby improving the assessment efficiency of the switching operation.

Since some steps do not require machine operation and only manual inspection is required, the status confirmation button must be pressed after the manual inspection is completed to indicate that this step is completed, which is convenient for the switching operation assessment and inspection.

The working efficiency of the switching operation evaluation system is improved.

After processing, the driving module M2 outputs a low level to the first relay K1, and the first relay K1 is closed, and the indicator light is turned on; wherein, the output module A5 includes six indicator lights corresponding to the fifth optocoupler unit U5 to the tenth optocoupler unit U10, and the connection method of the remaining optocoupler unit circuits is the same as that of the fifth optocoupler unit U5. The candidate's switching operation is evaluated according to the correct operation evaluation process. For each correct step, a corresponding indicator light is energized. If the step is wrong or the corresponding step status is not confirmed, the corresponding indicator light cannot be energized.
