Description

Technical Field

[0001] This invention belongs to the field of nuclear power plant operation procedures technology, specifically relating to a novel human-caused prevention tool applied to digital procedures. Background Technology

[0002] To reduce operational errors, nuclear power plants commonly use human error prevention tools. One such tool is monitoring, used for operations that may have immediate, irreversible, significant consequences or affect the stable operation of the unit. Monitoring procedures or tasks typically involve nuclear safety, industrial safety, radiation safety, environmental safety, and the stable operation of the power plant, and may have immediate, irreversible effects. Furthermore, during experience feedback or accident investigations, monitoring procedures recorded in the operation log are usually a key focus due to their importance; however, the lack of a record of the monitoring process creates difficulties for tracing back or investigating accidents. With the increasing use of digital procedures in power plant production and operation, monitoring, as a human error prevention tool, can be developed into new applications based on multimedia and information technology. This not only ensures that personnel strictly use monitoring tools and improves ease of use, but also allows the entire monitoring process to be recorded. Summary of the Invention

[0003] The purpose of this invention is to provide a novel human error prevention tool for digital procedures, which ensures that operators and supervisors strictly follow the monitoring steps and can easily record the monitoring process without reducing the effectiveness of the human error prevention tool.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A novel human error prevention tool for digital procedures adds a voice monitoring option to the human error prevention module of the digital procedure system, placing it alongside monitoring and self-testing functions; it also adds a voice reading function and intelligent voice recognition function to the digital procedure system; it confirms the existence of equipment code and target status fields in the digital procedure system's procedure database, otherwise creating these two fields as keywords for voice monitoring; when compiling digital procedures, voice monitoring is selected in the human error prevention requirement field for a specific operation step as needed; when executing the digital procedure to the step requiring voice monitoring, the required content is read aloud; and the executor... The user repeats the instructions via voice. The digital procedure system intelligently analyzes the user's voice to determine the match between the device code and the keywords in the target status field. If the requirements are met, it provides a positive conclusion and agrees to execute the step; otherwise, the step cannot be executed. After the user completes the operation, they provide voice feedback indicating whether the operation was completed or failed. The digital procedure system analyzes the voice and, if it determines that the operation was completed, automatically completes the current step and proceeds to the next step. If it determines that the operation failed, it pauses the current step. When the digital procedure system detects a step that requires monitoring, it records and saves the monitoring process.

[0006] Monitoring steps are steps that require monitoring and are identified and set during the development of digital procedures.

[0007] The configuration module allows you to configure monitoring within the digital procedure editor.

[0008] Each Pad terminal running the digital procedures serves as a client template.

[0009] When the Pad terminal executes the monitoring step, the recording function is automatically or manually activated to record the monitoring process. The recording ends automatically after the process is completed and the recording is saved to the server.

[0010] The beneficial effects achieved by this invention are as follows:

[0011] Through intelligent voice interaction, monitoring of human error prevention tools that previously required two operators can be performed by a single operator, improving labor productivity without compromising the effectiveness of these tools. In situations where manual operation of the terminal is unsuitable, such as in chemical handling, radiation areas where gloves prevent easy access, or when two hands are needed to operate the equipment, the "voice monitoring" function enables "zero-contact" execution of digital procedures, improving operational safety and efficiency. Real-time recording ensures that both the operator and monitor strictly adhere to monitoring procedures, recording the process for subsequent investigations and tracing, thus enhancing management. Attached Figure Description

[0013] Figure 2 A simplified diagram of digital procedural monitoring based on audio recording technology. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] This invention includes a monitoring method based on digital protocols using voice interaction and recording technologies.

[0016] 1. Digital procedure monitoring method based on voice interaction technology:

[0017] 1) Add a "voice monitoring" option to the human error prevention module of the digital procedure system, placing it alongside monitoring, self-testing, and other functions;

[0018] 2) Add a voice reading function to the digital procedure system;

[0019] 3) Add intelligent voice recognition function to the digital procedure system;

[0020] 4) Confirm that the "Procedure Database" of the digital procedure system contains the equipment code and target status fields; otherwise, create these two fields as keywords for voice monitoring.

[0021] 5) When developing digital procedures, select "Voice Monitoring" in the human factors prevention requirements field for a specific operation step, as needed.

[0022] 6) When the execution of the digital procedure reaches the step requiring "voice monitoring", the system will read aloud the content to be executed.

[0023] 7) The personnel responsible for the task repeat the instructions or instructions verbally.

[0024] 8) The digital procedure system intelligently analyzes the voice of the personnel performing the procedure to determine the degree of match between equipment codes and target status keywords. If the requirements are met, the system provides a positive conclusion and agrees to execute the step; otherwise, the step cannot be executed.

[0025] 9) After the operator completes the operation, they will receive voice feedback indicating "Operation completed" or "Operation failed".

[0026] 10) The digital procedure system analyzes the voice and determines that the operation is "completed". If it determines that the operation is "failed", it will automatically complete the current step and proceed to the next step. If it determines that the operation is "failed", it will pause the current operation step.

[0027] 2. Digital procedural monitoring methods and data recording techniques based on audio recording technology

[0028] 1) Based on the digital procedure system, when a step requiring monitoring is detected, the monitoring process is recorded and saved. This includes a configuration module, a client module, and a recording module.

[0029] 2) The monitoring steps refer to the steps that need to be monitored that are identified and set during the digital procedure writing process.

[0030] 3) The configuration module refers to the configuration of monitoring within the editor of the digital procedure.

[0031] 4) The client template refers to the Pad terminal that runs the digital procedure.

[0032] 5) The recording module refers to the Pad terminal automatically (or manually) activating the recording function when it reaches the monitoring step, recording the monitoring process, automatically ending the recording after execution, and saving the recording to the server.

[0033] Further explanation of the technical solution provided by the present invention:

[0034] like Figure 1 As shown, a new human error prevention tool, "Voice Monitoring," is added to the human error prevention module of the digital procedure system, alongside other tools such as self-inspection and monitoring. A "Smart Voice Recognition" function is developed within the digital procedure system, capable of identifying keywords from a speech and providing a positive or negative conclusion based on the recognition results. A "Voice Reading" function is also added; upon reaching a certain step, the system reads aloud the required content. When compiling digital procedures, the "Voice Monitoring" function can be selected in the human error prevention field as needed. When executing a digital procedure, the system first retrieves information from the procedure database, including the current step's operation content, equipment code, target status, and human error prevention requirements. If "Voice Monitoring" is set in the current step's human error prevention field, the system converts the operation content into speech and reads it aloud using the TTS (Text-to-Speech) function. The executor then repeats the required content verbally. The focus of the repetition is on the equipment code and target status. The system uses "Smart Voice Recognition" to intelligently analyze the executor's speech, determining the degree of match between the equipment code and target status keywords. If the requirements are met, the system will provide a positive response and agree to proceed with the steps. Otherwise, the steps cannot be executed, the system will remind the operator to repeat the steps, and will then proceed to the next section. After completing the operation, the operator will provide voice feedback on the result, typically "Operation completed" or "Operation failed." If the system recognizes "Operation completed," it will automatically proceed to the next step; if it recognizes "Operation failed," it will pause the operation and wait for the operator to handle it.

[0035] like Figure 2As shown, on the PC, a monitoring tool is configured for the operation steps of the digital procedure. After the mobile device executes the step that has been configured for monitoring, the mobile device monitor verifies the monitor's identity information and the monitoring steps, and selects recording as the mode of use for the monitoring tool. The recording module is automatically activated, the operator begins to execute the operation steps, and the recording module records the entire monitoring execution process. Once the monitoring steps are completed, the recording stops automatically (or can be stopped manually in advance), and a recording monitoring record is generated.
