[0002] To ensure the stable operation of nuclear power units, the accuracy of the instrumentation and control system operation is crucial. To prevent human errors, operators need to take a variety of preventive measures when handling DCS (distributed control systems) and field equipment, such as "three-stage communication" and "star self-inspection". Among these measures, the guardianship system is one of the most important. The guardianship system mainly refers to the process in which an operator and a guardian participate together when performing critical or high-risk operations. This system requires the operator to verbally state the operating instructions and point to the relevant equipment before performing the operation, and then the guardian confirms the equipment pointed to. After verifying that the instructions are correct, the operator can obtain the guardian's consent to operate.

[0003] However, the monitoring system requires operators to have a high level of skills and be familiar with the environment, and the on-site environment may cause them greater stress and fatigue, leading to human factors failures. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0042] Figure 1The figure is a flow chart of an auxiliary method for preventing human error in one embodiment. DETAILED DESCRIPTION

[0043] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0044] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0045] The embodiment of the present invention provides an auxiliary method for preventing human error. Figure 1 As shown, the auxiliary method for preventing human error operation includes the following steps:

[0046] Obtain all operation steps of the operation work order of the DCS system, the equipment to be operated corresponding to the operation steps, and the operation parameters corresponding to the equipment to be operated.

[0047] Specifically, the operation work order of the DCS system can be a paper work order or an electronic work order.

[0048] In some scenarios, all steps and equipment in the operation work order are controlled on the DCS system.

[0049] Optionally, when the operation work order of the DCS system is a paper work order, the paper work order is digitized, and the digitized work order information is named using the work order number or work subject. If the operation work order of the DCS system is an electronic work order, the corresponding work order is searched by the work order number or work subject and other information, and all the operation steps of the work order, the equipment to be operated corresponding to the operation steps, and the operation parameters corresponding to the equipment to be operated are obtained.

[0050] Optionally, by acquiring image information of a display interface of the DCS system, identification information of a target device controlled by the DCS system is acquired, and it is determined whether the identification of the target device belongs to the identification of the device to be operated.

[0051] Specifically, on the display interface of the DCS system, each device has a unique identifier. By obtaining the identifier and other identification information of the target device, it is determined whether the target device belongs to the device to be operated, that is, whether the identifier of the target device belongs to the identifier of the device to be operated in the operation work order.

[0052] Furthermore, the work order information of the operation work order includes the identification of the device to be operated. When all the operation steps of the operation work order of the DCS system, the devices to be operated corresponding to the operation steps, and the operation parameters corresponding to the devices to be operated are obtained, the work order information of all the operation work orders can also be obtained.

[0053] Optionally, the identification information of the target device includes image information of the target device displayed on the display interface of the DCS system. The image information includes the identifier (or device code) of the target device and the device icon. The identification of the target device belongs to the identification of the device to be operated only when the identifier matches the device to be operated.

[0054] Furthermore, the image information also includes parameters of the device to be operated.

[0055] Depending on the complexity of the DCS system interface, only the identifier or device code may be used for judgment, and no limitation is made here.

[0056] If the identifier of the target device belongs to the identifier of the device to be operated, the parameter information of the target device is obtained after receiving the parameter acquisition instruction.

[0057] Optionally, after the user operates the target device, parameter information of the target device is obtained by receiving a parameter acquisition instruction issued by the user.

[0058] Specifically, on the display interface of the DCS system, select the corresponding target device according to the confirmed device identification. In some scenarios, the DCS system will display the real-time parameters of the device, such as temperature, pressure, flow, liquid level, etc. These parameters are usually displayed next to the device identification or in the device details interface. The parameters next to the device identification will be used as part of the identification information and will be obtained uniformly when obtaining the identification information.

[0059] Optionally, the device status is represented by different device icons. For example, when the valve status is open, the device icon of the device is an indicator light off; when the valve status is closed, the device icon of the device is an indicator light on. By judging the valve identification, the parameter information of the valve status can be obtained.

[0060] Determine whether the parameter information is consistent with the operation parameters; if they are consistent, it is determined that the operation of the device to be operated is completed; if they are inconsistent, an alarm is issued.

[0061] If the parameter information matches the operating parameters, it indicates that the operation of the target device has been successfully completed, and this status is recorded in the operation log. If the parameters are found to be inconsistent, an alarm will be triggered, and the operator will check the device status again to determine the cause of the deviation and whether correction is required. At the same time, all alarm events and parameter information are recorded in the system log, and maintenance personnel or other relevant personnel will be notified when necessary.

[0062] Determine whether all devices to be operated in the operation steps have been completed. If all are completed, prompt to end the operation.

[0063] Automatically determine whether all the equipment to be operated in the operation order has been completed, and send an end prompt to the operator after all are completed. It not only improves operation efficiency, reduces human errors, and enhances safety, but also facilitates recording and tracking of the operation process, optimizes the workflow, and ensures production continuity and equipment stability.

[0064] The present invention identifies the identification information of the target device on the display interface of the DCS system, verifies, monitors and reminds the target device operated by the operator according to the operation work order, thereby effectively improving the accuracy and safety of the operation and reducing the risk of misoperation. It improves the operation efficiency through automated processes, and real-time monitoring ensures that the operation is performed according to the predetermined parameters and processes. The timely reminder function avoids the continuation of errors and reduces potential losses. In addition, the system recording and auditing functions enhance the traceability of operations and optimize maintenance plans and fault responses. The present invention also improves production quality, reduces the impact of human factors, and enhances user experience, making the operation more intuitive and convenient, thereby reducing operational risks and maintenance costs while improving overall production efficiency and product quality.

[0065] In some executable embodiments, obtaining all operation steps of an operation work order of a DCS system, devices to be operated corresponding to the operation steps, and operation parameters corresponding to the devices to be operated includes:

[0066] Acquire at least one paper work order image.

[0067] It should be noted that the operation work order includes a paper work order. Optionally, the paper work order is imaged by a smart terminal to obtain an image of the paper work order.

[0068] Use table extraction technology to obtain table information on paper work order images.

[0069] Specifically, the table information includes table layout information.

[0070] The operation step related columns are obtained from the table information through keyword extraction technology; the operation step related columns are the columns in the table information that record the operation steps.

[0071] Specifically, keyword extraction technology can be used to efficiently identify and extract specific columns related to operation steps from table information. Operation step related columns refer to those columns that record the operation process, step sequence, specific actions or related instructions in detail in the table. Keyword extraction technology can be used to quickly access and organize detailed information on operation steps, thereby improving work efficiency, ensuring the accuracy and consistency of operations, significantly reducing the time for manual interpretation and data entry, and reducing the error rate. According to the work order information in the operation step related columns, the operation steps, all equipment to be operated, and operation parameters of all paper work order images are obtained.

[0072] Furthermore, the operation steps of all paper work order images, all devices to be operated and the operation parameters are synchronized to the work order records of the relevant devices, and the relevant devices save the operation steps and titles of the work orders. Specifically, the relevant devices may be computers.

[0073] By digitizing the paper work order image, all the operation steps of the operation work order, the equipment to be operated corresponding to the operation steps, and the operation parameters corresponding to the equipment to be operated are obtained, preventing work order recognition errors caused by human errors.

[0074] Digitization of paper work orders, including:

[0075] Use a smart terminal to scan the paper version of the work order to be executed and obtain the paper work order image.

[0076] Use table extraction technology to obtain table information on the paper work order image; edit the table information to obtain the work order data to be saved.

[0077] In some scenarios, there may be recognition anomalies in the table information, and the user is required to edit and modify the table information to obtain the work order data to be saved.

[0078] Determine whether the work order data to be saved exists in the database.

[0079] It can be understood that the database is deployed in a related device, such as a computer.

[0080] If the work order data to be saved does not exist in the database, the work order data to be saved will be formatted.

[0081] Synchronize the formatted work order data to be saved to the database.

[0082] In some executable embodiments, according to the work order information in the operation step related column, the operation steps of all paper work order images, all devices to be operated and the operation parameters are obtained, including:

[0083] Extract equipment information and parameters from work order information according to preset rules.

[0084] Optionally, the device information and parameters in the work order information are extracted by regular expressions and rules. The preset rules include preset regular expressions and keyword extraction rules.

[0085] In some scenarios, operators can manually adjust the extracted device information, such as editing the device code. Arrange the device information and parameters in the order in which they appear in the work order information to obtain all the operation steps, devices to be operated, and operation parameters.

[0086] Optionally, sort the devices according to the structure of the text in the operation ticket and the order in which they appear in the operation ticket.

[0087] Furthermore, the device codes of the devices to be operated are output to the to-be-operated list in the order of arrangement, and at the same time, an empty executed list is generated.

[0088] In some executable embodiments, obtaining identification information of a target device and determining whether the identification of the target device belongs to the identification of a device to be operated includes:

[0089] The identification displayed by the target device is collected by an image acquisition device to obtain identification information.

[0090] Specifically, the identification information includes an icon and a code corresponding to the target device. The image acquisition device may be an intelligent device with a shooting function.

[0091] Identify whether the target device is the device to be operated through the identification information.

[0092] The text or symbol in the logo is extracted by using image processing technology. After the logo information is obtained, it is compared with the pre-stored logo information of the device to be operated to identify whether the target device is the device to be operated.

[0093] If the target device does not belong to the device to be operated, an alarm will be issued.

[0094] If the comparison result shows that the target device does not belong to the device to be operated, the system will trigger an alarm mechanism. This alarm can be a visual, auditory or tactile prompt, the purpose of which is to immediately notify the operator to check the situation to prevent possible incorrect operation or potential safety risks.

[0095] The present invention improves the accuracy and safety of operation based on identification information and alarms, especially in automated and semi-automated working environments, and can effectively reduce human errors and ensure the compliance of operations and the safety of equipment.

[0096] In some executable embodiments, the identification information also includes parameter information identifying the corresponding device.

[0097] In some scenarios, the icons on the display interface of the DCS system have parameter meanings, such as the indicator light icon green means on, red means off; the pressure gauge icon displays the real-time pressure value of the device, sometimes in the form of an analog pointer or digital reading. On, off, and real-time pressure values ​​are all parameter information, which vary from device to device.

[0098] Therefore, obtaining parameter information through identification information can more quickly determine whether the current device parameters need to be adjusted again.

[0099] In some executable embodiments, obtaining parameter information of the device further includes:

[0100] The device parameters displayed on the display interface of the DCS system are collected through the image acquisition device to obtain parameter information.

[0101] Furthermore, the device parameter interface of the DCS system can be opened, the device parameters displayed on the display interface of the DCS system can be displayed, and the corresponding parameter images can be collected by using an image acquisition device to finally obtain parameter information.

[0102] In some executable embodiments, if the target device is a device to be operated, it is determined whether the target device is the current device to be operated; if the target device is not the current device to be operated, a reminder is given.

[0103] It is understandable that there is an operation sequence among the multiple devices to be operated. If the target device is one of the devices to be operated but is not the first device in the sequence, an alarm is issued. The present invention can ensure that the operator can promptly identify and correct any unexpected device operation during the operation, thereby improving the accuracy and safety of the operation and reducing operation errors and potential production risks.

[0104] In some executable embodiments, if the target device is not the device to be currently operated, a reminder is given, including:

[0105] If the target device is not the device to be operated, a step skip reminder will be given.

[0106] Specifically, when it is determined that the target device is not the device to be currently operated, the step skipping reminder function will be automatically triggered to notify the operator that the current operation does not conform to the predetermined process.

[0107] Furthermore, when the devices to be operated are ranked, and the target device is not ranked first among the devices to be operated, a skip operation is prompted.

[0108] Skip operation can reduce unnecessary steps, thereby improving the efficiency of the operation, especially in emergency situations, so that it can respond quickly and take necessary measures. And skip operation provides a flexible response mechanism, allowing operators to quickly adjust the operation steps according to the actual situation to adapt to the changing environment.

[0109] Receive a step skip instruction, find the corresponding step according to the target device, and verify the operation parameters of the corresponding step.

[0110] Specifically, after receiving the step skip reminder, the operator can decide whether to accept the step skip instruction. If accepted, the corresponding operation steps will be found according to the target device identification. After the corresponding operation steps are found, the operation parameters in these steps will be extracted and verified with the parameters of the target device.

[0111] Further, when the devices to be operated are ranked, and the target device is ranked first among the devices to be operated, a prompt indicating that the operation is successful is displayed. In some executable embodiments, if the parameter information is consistent with the operation parameter, it is determined whether the current operation step is completed;

[0112] If the current operation step is completed, determine whether all operation steps are completed.

[0113] If the current operation step is not completed, return to the current operation step and verify again.

[0114] Specifically, after the user completes the operation, he can judge whether his operation is successful. If the operation is successful, he can choose to proceed to the next step. If he thinks his operation has a problem, he can choose to re-execute and return to the current step to re-execute until the user completes the operation and confirms that the operation is successful.

[0115] In some executable embodiments, the method further includes:

[0116] All operation steps of the DCS operation work order are divided into an unexecuted list and an executed list.

[0117] It is understandable that by dividing the operation steps into an unexecuted list and an executed list, you can quickly distinguish which steps have not been executed and which have been completed, so as to arrange the work more targeted and improve work efficiency. At the same time, clearly listing the unexecuted steps helps reduce operational omissions and ensure that all necessary steps are executed.

[0118] Furthermore, the contents of the unexecuted list and the executed list may include operation device codes. The device codes are arranged in the unexecuted list in the order of execution.

[0119] Specifically, the operation equipment code is obtained from the operation work order.

[0120] After the current operation steps are completed, it also includes:

[0121] Move the current pending execution device from the unexecuted list to the executed list.

[0122] Move the pending devices in the unexecuted list that are ranked after the current pending devices to be executed to the front one position.

[0123] Specifically, the instruction issued by the operator is received to determine whether the current operation step has been completed. If the current operation step has been completed, the current execution device is placed in the executed device (executed list), and all the remaining execution devices are moved forward one position.

[0124] After the user clicks "Complete" or "Re-execute", the smart terminal updates the internal state according to the clicked item. If the user clicks "Complete", the smart terminal considers that the current step has been completed, and puts the current execution device into the completed execution device, and moves all the remaining execution devices forward one step.

[0125] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
