After the supervisor is informed, he or she confirms the correctness of the work steps to be performed and releases them through the human-computer interaction device, which authorizes the work group to perform the important operation; d. The work is performed under the full supervision of the supervisor; e. After the execution is completed and confirmed to be correct, the supervisor confirms it on the human-computer interaction device, and the work group can proceed to the next steps;
[0008] The self-check process includes the following steps: a. After the steps are completed, the human-computer interaction device improvement workgroup needs to conduct a self-check of the operation steps; b.

[0017] The beneficial effects achieved by the present invention are:
[0018] This method effectively combines several tools to prevent human error, effectively reducing human error during the maintenance and operation of critical equipment. The system replaces existing paper work packages, which make it easier to falsify work afterward, such as by adding signatures.

[0038] Take the dismantling inspection of a motor running on site as an example. The specific steps are as follows:
[0039] The disassembly work includes: a. first cut off the power supply and provide necessary protection and fixation to the motor; b. measure and record the important parameters of the motor; c. disassemble the motor (remove the end cover, remove the rotor, remove the stator, remove the bearing, etc.); d. clean the parts; e. replace the damaged parts; f. assemble the motor (install the bearing, install the stator, install the rotor, and seal the end cover); g. confirm the correctness of the assembled parts (position, direction, tightening force); h. measure and record the important parameters of the motor after repair; i. conduct quality inspection and operation test;
[0040] 1. During the work preparation phase, the person preparing the work enters the maintenance object and operating steps into the human-computer interaction device. To prevent the work group from cutting off the power supply to other parallel motors, [Anti-Human Error Tool 2, Other Person Supervision] is set before step a. To prevent personnel from improperly transferring motors, [Anti-Human Error Tool 3, Self-Check] is set after step f.
[0041] The human-computer interaction device automatically imports the relevant data of the disassembly of the same type of motor. When the working group performs step h. to measure and record the important parameters of the motor after repair, if the recorded data is obviously abnormal, the human-computer interaction device will automatically remind the working group to re-measure or repair to ensure that the data is reasonable.
[0042] 2. The working group brings the human-computer interaction equipment to the work site, finds the motor to be repaired, and uses the human-computer interaction equipment to take pictures of the motor to be disassembled. The human-computer interaction equipment uses image recognition and compares it with the repair object entered by the preparer before, confirms that the work object is correct, prompts the working group that the work object is correct, and allows subsequent operations to be performed.
[0043] 3. After the working group arranges the work area and places the necessary tools, click on the human-computer interaction device to execute [Tool 1: Pre-work confirmation and discussion] to confirm that the people, machines, materials, methods, and environment required for this work are all available, and confirm each one on the interactive device; based on the problems that the human-computer interaction device prompts about similar work, discuss the points to pay attention to during this maintenance process; internally discuss the division of labor and precautions during the execution of the work, and the human-computer interaction device automatically records the time and content of the specific discussion to ensure that the working group will not omit this step due to laziness. This can also be used for analysis and investigation after problems arise.
[0044] The work group clicks the human-computer interaction device to prepare for step a. First, cut off the power. The human-computer interaction device is configured according to the preparer's settings. This step requires the use of [Anti-Human Error Tool 2, Supervision]. The work group contacts a higher-level person outside the work group for on-site supervision. The supervisor confirms their identity through the human-computer interaction device. The work group clearly informs the supervisor that they will be cutting off the power to the motor. A wrong operation will cause other motors to stop operating, resulting in significant losses. Once informed, the supervisor confirms the correctness of the power cut and, after clearing the way through the human-computer interaction device, authorizes the work group to perform this important operation. The work group performs the power cut under the full supervision of the supervisor. After the operation is completed and confirmed to be correct, the supervisor confirms it on the human-computer interaction device, and the work group can proceed to the next steps.
[0045] 4. The work group follows the steps in the human-machine interaction device's sequence. b. Measure and record the motor's key parameters.

[0046] 5. The working group performs the following steps in sequence: c. Disassembling the motor (removing the end cover, taking out the rotor, removing the stator, removing the bearings, etc.); d. Cleaning the parts; e. Replacement of damaged parts, and confirms each step on the human-computer interaction device.
[0047] 6. After the work group performs work step f. assembling the motor (installing bearings, installing the stator, installing the rotor, and encapsulating the end caps), the human-machine interaction device prompts them to perform [Anti-Human Error Tool 3, Self-Check]. The work group inspects the installation of the bearings, stator, rotor, and end caps and discovers that the rotor is installed backwards. After reassembly, they confirm correct installation on the human-machine interaction device. The human-machine interaction device allows the work group to proceed to the subsequent steps.
[0048] 7. The work group performed work step g. Confirmed the correctness of the assembled parts (position, orientation, tightening force); h. Measured and recorded important parameters of the repaired motor. The staff member made a simple mistake while recording the data and recorded 23.32 as 233.2, which automatically triggered [Anti-Human Error Tool 4, Machine Prompt]. The work group re-measured and re-entered the correct data into the human-computer interaction device according to the prompt of the human-computer interaction device.
[0049] 8. The work group performs work step i. Conducts quality inspection and operational tests. If the results are normal, the work is completed.
