Description

Technical Field

[0001] This invention relates to the field of human error prevention technology in nuclear power plants, and in particular to a human error prevention system and method for nuclear power plants based on LBS and work objects. Background Technology

[0002] During operation at a nuclear power plant, human errors such as entering the wrong bay or misoperating other equipment can easily occur, leading to equipment damage, shutdowns, and reactor failures, causing significant economic losses to the nuclear power plant. Therefore, preventing human error during nuclear power plant operations has become a crucial issue in the safety and reliability management of nuclear power plants. Summary of the Invention

[0003] Therefore, it is necessary to provide a system and method for preventing human error in nuclear power plant operations based on LBS and work objects to avoid human error during the work process. This method integrates the content of work orders or operation tickets with the location of personnel indoor positioning equipment to realize the application of tools to prevent human error, thereby avoiding the high-risk situation of going to the wrong bay.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A human error prevention system for nuclear power plants based on LBS and work objects includes a personnel LBS positioning system, an equipment location management system, a work content management system, and a human error prevention decision system.

[0006] The equipment location management system stores the location information of all equipment in the nuclear power plant, enabling the retrieval and matching of equipment information around personnel.

[0007] The work content management system stores equipment information related to the work content of all personnel in the nuclear power plant, enabling the retrieval and matching of equipment information related to personnel's work content.

[0008] The personnel LBS positioning system is used to locate personnel location information in real time during the work order commencement process and send it to the anti-human factor decision-making system.

[0009] The anti-human-cause decision system is used to receive personnel location information sent by the personnel LBS positioning system and determine whether the personnel stay exceeds the threshold.

[0010] If a person's stay exceeds the threshold, the human error prevention decision system calls the equipment location management system to query information on important equipment around the person, and calls the work content matching system to query equipment involved in the person's work content. Based on the matching degree between important equipment around the person and equipment involved in the person's work content, the system conducts risk assessment and provides corresponding human error prevention decisions and alarms.

[0011] Furthermore, the personnel LBS positioning system includes, but is not limited to, using wireless positioning to locate personnel's location information in real time during the commencement of work.

[0012] Furthermore, the personnel LBS positioning system includes an LBS positioning terminal; the LBS positioning terminal is used to acquire the real-time positioning information of the workers and send it to the human factors prevention decision-making system.

[0013] Furthermore, the LBS terminal includes a handheld communication tool equipped with an RFID card and a network communication device. It uses a beamforming algorithm to calculate personnel location information through AP base stations and / or 5G base stations in the factory. At the same time, an RFID reader is installed near the SPV equipment to trigger real-time monitoring of personnel location information when personnel approach, thereby realizing real-time positioning of personnel in the factory.

[0014] Furthermore, the personnel LBS positioning system also includes an access control system; the access control system is used to acquire basic personnel location information and send it to the anti-human factor decision-making system.

[0015] Furthermore, the personnel LBS positioning system also includes a communication terminal; the communication terminal is used to acquire the communication location information of the workers and send it to the anti-human factors decision-making system. The communication terminal includes a factory landline telephone and a mobile phone, and the workers communicate with the operation personnel of the operation department through the factory landline telephone or mobile phone during the operation process.

[0016] Furthermore, the device location management system includes a device information storage system and a device location input system; the device location input system is used to input the device's location information and parameter information and send them to the device information storage system; the device information storage system is used to receive and store the device's location information and parameter information.

[0017] Furthermore, the human error prevention decision-making includes decision-making regarding the wrong-way interval, decision-making regarding the risk control of SPV equipment, and decision-making regarding the workflow management.

[0018] The decision-making process for determining whether personnel have entered the wrong unit is as follows: if personnel appear in other units after starting work, it is judged as an extremely high-risk level; if personnel appear in other non-working areas of the factory after starting work, it is judged as a high-risk level.

[0019] The risk management decision-making process for SPV equipment determines whether there are staff members staying near the SPV equipment. If staff members are staying near the SPV equipment, it is determined to be a high-risk level. At the same time, the staff members are asked to stay for a certain period of time, and any abnormalities are reported.

[0020] The workflow management decision-making process determines whether personnel are seriously violating the factory's sequence of operations. If personnel are found to be seriously violating the factory's sequence of operations, a risk is identified, and risk confirmation needs to be requested from the personnel.

[0021] Furthermore, the alarms include master control alarms, terminal alarms, and operational site alarms;

[0022] The main control alarm indicates an extremely high risk that requires immediate confirmation from the main control personnel. The human factor prevention decision system will pop up a confirmation window for wrong intervals, and at the same time provide information such as the personnel who went to the wrong interval, work start information, personnel location and contact information.

[0023] The terminal alarm is an alarm from the LBS positioning terminal of the worker, reminding the worker whether they have gone to the wrong interval, etc.

[0024] The alarms at the operation site are those that do not require direct intervention from operation personnel but pose certain risks. They can be sent directly to the duty room at the operation site for verification.

[0025] A method for preventing human error in nuclear power plants based on location-based services (LBS) and work objects, using the aforementioned LBS-based human error prevention system for nuclear power plants, includes the following steps:

[0026] 1. After the work permit is issued, the LBS positioning terminal of the personnel involved is activated and enters the work mode. The location information of the personnel is located in real time and sent to the anti-human factors decision system.

[0027] 2. The anti-human factor decision system receives the location information of the workers sent by the personnel LBS positioning system and determines whether the time the workers stay at a certain location exceeds the threshold.

[0028] 3. If a worker stays at a certain location for more than a threshold time, the human error prevention decision system calls the equipment location management system to query the equipment information around the worker and the work content management system to query the equipment information involved in the worker's work content. Based on the matching degree between the equipment information around the worker and the equipment information involved in the worker's work content, the system performs risk assessment and provides corresponding human error prevention decisions and alarms.

[0029] Furthermore, if the information on the equipment around the workers does not match the information on the equipment involved in the workers' work, the risk prevention decision system determines the risk level of the workers and sends corresponding alarm information to the LBS positioning terminals involved in the workers' work.

[0030] The LBS positioning terminal receives and displays alarm information sent by the human factors decision-making system to inform the workers of the current risk level and request them to leave.

[0031] If the workers have not yet left, the decision-making system will notify the operations department to verify whether there is any risk.

[0032] When the work is completed and the work order is closed, the LBS positioning terminal of the person who started the work will be automatically turned off and the LBS positioning terminal of the person who started the work will exit the work mode.

[0033] Furthermore, if the equipment information around the operator belongs to a different unit than the equipment information involved in the operator's work, the anti-human factors decision system determines that the operator has gone to the wrong unit and is at an extremely high risk level. It sends an error interval alarm to the LBS positioning terminal of the operator and pops up an error interval confirmation window for the main control personnel to confirm with the anti-human factors decision system whether the operator has gone to the wrong interval.

[0034] The LBS positioning terminal of the workers received and displayed the wrong interval alarm information sent by the anti-human factor decision system to inform the workers that they had entered the wrong unit and were currently in an extremely high-risk state, and requested the workers to leave.

[0035] The alarm information for the person who went to the wrong interval includes the person's basic information, work start information, location information, and contact information.

[0036] Furthermore, if the equipment information around the operator and the equipment information involved in the operator's work belong to different equipment in the same unit, the human factors prevention decision system determines that the operator is near a non-operational object in the same unit and is at a high risk level. The system then sends an abnormal operation alarm to the LBS positioning terminal of the operator. The LBS positioning terminal receives and displays the abnormal operation alarm sent by the human factors prevention decision system to inform the operator of the abnormal operation. At the same time, an abnormal operation confirmation window pops up so that the operator can verify with the human factors prevention decision system whether the operation is abnormal.

[0037] Furthermore, if the equipment around the worker is an SPV device and the current device is not a working object, the human error prevention decision system determines that the current device is a non-working device and sends a non-working device alarm message to the LBS positioning terminal of the worker. The LBS positioning terminal of the worker receives and displays the non-working device alarm message sent by the human error prevention decision system to inform the worker that the current device is a non-working device. At the same time, a non-working device confirmation window pops up, allowing the worker to provide confirmation information to the human error prevention decision system. The confirmation information includes whether an anomaly has been found and whether there is any information that needs to be fed back.

[0038] Furthermore, when the human risk prevention decision system confirms a high risk to the construction personnel, if the construction personnel do not confirm the risk within the set time, the human risk prevention decision system will notify the operation personnel to carry out risk management based on the actual prefabrication plan.

[0039] Beneficial technical effects of the present invention:

[0040] The present invention relates to a human error prevention system and method for nuclear power plants based on LBS and work objects. By integrating the content of work orders or operation tickets with the location of personnel indoor positioning equipment, the application of human error prevention tools is realized, thereby avoiding high-risk situations such as going to the wrong bay.

[0043] Figure 3 This is a topology diagram of the human error prevention system architecture for nuclear power plants based on LBS and work objects, as presented in this invention. Detailed Implementation

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0045] Example 1

[0046] See Figure 1-3 This invention provides a human error prevention system for nuclear power plants based on LBS and work objects, including a personnel LBS positioning system, an equipment location management system, a work content management system, and a human error prevention decision system;

[0047] The equipment location management system stores parameter and location information of all equipment in the nuclear power plant, enabling the retrieval and matching of equipment information around personnel.

[0048] The work content management system stores equipment information related to the work content of all personnel in the nuclear power plant, enabling the retrieval and matching of equipment information related to personnel's work content.

[0049] The personnel LBS positioning system is used to locate personnel location information in real time during the work order commencement process and send it to the anti-human factor decision-making system.

[0050] The anti-human-cause decision system is used to receive personnel location information sent by the personnel LBS positioning system and determine whether the personnel stay exceeds the threshold.

[0051] If a person's stay exceeds the threshold, the human error prevention decision system calls the equipment location management system to query information on important equipment around the person, and calls the work content matching system to query equipment involved in the person's work content. Based on the matching degree between important equipment around the person and equipment involved in the person's work content, the system conducts risk assessment and provides corresponding human error prevention decisions and alarms.

[0052] Furthermore, the personnel LBS positioning system includes, but is not limited to, using wireless positioning to locate personnel's location information in real time during the commencement of work.

[0053] Furthermore, the personnel LBS positioning system includes an LBS positioning terminal; the LBS positioning terminal is used to acquire the real-time positioning information of the workers and send it to the human factors prevention decision-making system.

[0054] Furthermore, the LBS terminal includes a PDA or other handheld communication tool equipped with an RFID card and a network communication device. It uses multiple base stations, such as AP base stations and / or 5G base stations in the factory, to calculate the personnel location information using a beam positioning algorithm. At the same time, an RFID reader is installed near the SPV equipment to trigger real-time monitoring of personnel location information when personnel approach, thereby realizing real-time positioning of personnel in the factory.

[0055] Furthermore, the personnel LBS positioning system also includes an access control system; the access control system is used to acquire basic personnel location information and send it to the anti-human factor decision-making system. Specifically, the nuclear power plant manages the plant area by zone according to actual work needs. To enter different plant areas, personnel need to swipe a work ticket. The personnel work ticket information includes basic personnel information, personnel work content, and work target information. It can directly verify whether personnel are in non-work areas after starting work. The access control system can serve as the initial positioning guarantee to confirm that the personnel are in a normal area.

[0056] Furthermore, the personnel LBS positioning system also includes a communication terminal; the communication terminal is used to acquire the communication location information of the workers and send it to the anti-human factors decision-making system. The communication terminal includes a factory landline telephone and a mobile phone, and the workers communicate with the operation personnel of the operation department through the factory landline telephone or mobile phone during the operation process.

[0057] Furthermore, the device location management system includes a device information storage system and a device location input system; the device location input system is used to input the device's location information and parameter information and send them to the device information storage system; the device information storage system is used to receive and store the device's location information and parameter information.

[0058] Furthermore, the human error prevention decision-making includes decision-making regarding the wrong-way interval, decision-making regarding the risk control of SPV equipment, and decision-making regarding the workflow management.

[0059] The decision-making process for the wrong entry interval includes: determining whether the personnel have entered the wrong unit; if the personnel appear in other units after starting work, it is judged as an extremely high risk level; if the personnel appear in other non-working areas of the factory after starting work, it is judged as a high risk level.

[0060] The risk management decision-making process for the SPV equipment includes determining whether there are staff members staying near the SPV equipment; if staff members are staying near the SPV equipment, it is determined to be a high-risk level, and the staff members are asked to stay for a certain period of time, and any abnormalities are reported.

[0061] In critical operations, there is a specific order of operations. The workflow management decision-making process determines whether personnel are seriously violating the factory's order of operations. If personnel are seriously violating the factory's order of operations, a risk is identified, and risk confirmation needs to be requested from the personnel.

[0062] Furthermore, the alarms include master control alarms, terminal alarms, and operational site alarms;

[0063] The main control alarm indicates an extremely high risk that requires immediate confirmation from the main control personnel. The human factor prevention decision system will pop up a confirmation window for wrong intervals, and at the same time provide information such as the personnel who went to the wrong interval, work start information, personnel location and contact information.

[0064] The terminal alarm is an alarm from the LBS positioning terminal of the worker, reminding the worker whether they have gone to the wrong interval, etc.

[0065] The alarms at the operation site are those that do not require direct intervention from operation personnel but pose certain risks. They can be sent directly to the duty room at the operation site for verification.

[0066] A method for preventing human error in nuclear power plants based on location-based services (LBS) and work objects, using the aforementioned LBS-based human error prevention system for nuclear power plants, includes the following steps:

[0067] 1. After the work permit is issued, the LBS positioning terminal of the worker is activated and enters the work mode. The LBS positioning terminal of the worker is located in real time and sent to the anti-human factor decision system to realize real-time monitoring of the worker's location.

[0068] 2. The anti-human factor decision system receives the location information of the workers sent by the personnel LBS positioning system and determines whether the time the workers stay at a certain location exceeds the threshold.

[0069] 3. If a worker stays at a certain location for more than a threshold time, the human error prevention decision system calls the equipment location management system to query the equipment information around the worker and the work content management system to query the equipment information involved in the worker's work content. Based on the matching degree between the equipment information around the worker and the equipment information involved in the worker's work content, the system performs risk assessment and provides corresponding human error prevention decisions.

[0070] Furthermore, if the information on the equipment around the workers does not match the information on the equipment involved in the workers' work, the risk prevention decision system determines the risk level of the workers and sends corresponding alarm information to the LBS positioning terminals involved in the workers' work.

[0071] The LBS positioning terminal receives and displays alarm information sent by the human factors decision-making system to inform the workers of the current risk level and request them to leave.

[0072] If the workers have not yet left, the decision-making system will notify the operations department to verify whether there is any risk.

[0073] When the work is completed and the work order is closed, the LBS positioning terminal of the person who started the work will be automatically turned off and the LBS positioning terminal of the person who started the work will exit the work mode.

[0074] Furthermore, if the equipment information around the operator belongs to a different unit than the equipment information involved in the operator's work, the human error prevention decision system determines that the operator has gone to the wrong unit and is at an extremely high risk level. The system sends an error interval alarm to the LBS positioning terminal of the operator and at the same time, the human error prevention decision system pops up an error interval confirmation window for the main control personnel to confirm with the human error prevention decision system whether the operator has gone to the wrong interval.

[0075] The LBS positioning terminal of the workers received and displayed the wrong interval alarm information sent by the anti-human factor decision system to inform the workers that they had entered the wrong unit and were currently in an extremely high-risk state, and requested the workers to leave.

[0076] The alarm information for the person who went to the wrong interval includes the person's basic information, work start information, location information, and contact information.

[0077] Furthermore, if the equipment information around the operator and the equipment information involved in the operator's work belong to different equipment in the same unit, the human factors prevention decision system determines that the operator is near a non-operational object in the same unit and is at a high risk level. The system then sends an abnormal operation alarm to the LBS positioning terminal of the operator. The LBS positioning terminal receives and displays the abnormal operation alarm sent by the human factors prevention decision system to inform the operator of the abnormal operation. At the same time, an abnormal operation confirmation window pops up so that the operator can verify with the human factors prevention decision system whether the operation is abnormal.

[0078] Furthermore, if the equipment around the worker is an SPV device and the current device is not a working object, the human error prevention decision system determines that the current device is a non-working device and sends a non-working device alarm message to the LBS positioning terminal of the worker. The LBS positioning terminal of the worker receives and displays the non-working device alarm message sent by the human error prevention decision system to inform the worker that the current device is a non-working device. At the same time, a non-working device confirmation window pops up, allowing the worker to provide confirmation information to the human error prevention decision system. The confirmation information includes whether an anomaly has been found and whether there is any information that needs to be fed back.

[0079] Furthermore, when the human risk prevention decision system confirms a high risk to the construction personnel, if the construction personnel do not confirm the risk within the set time, the human risk prevention decision system will notify the operation personnel to carry out risk management based on the actual prefabrication plan.

[0080] A simplified example of a human factor-based decision-making scheme is as follows:

[0081] a) When personnel are near equipment 1AAA001BBB, and the work information shows that their work equipment is 2AAA001BBB, the human error prevention decision system sends an "incorrect interval" alarm to the LBS positioning terminal of the personnel. The LBS positioning terminal receives and displays the "incorrect interval" alarm from the human error prevention decision system to inform the personnel that they have entered the wrong unit and are currently in an extremely high-risk state, requesting them to leave. The human error prevention decision system pops up a "incorrect interval" confirmation window for the main control personnel to confirm with the system whether the personnel have entered the wrong interval. The "incorrect interval" alarm information includes the basic information of the personnel who entered the wrong interval, work information, location information, and contact information.

[0082] b) When personnel are stationed near equipment 1AAA001BBB, and the work commencement information shows that their working equipment is 1AAA002BBB, the human error prevention decision system sends an abnormal work commencement alarm to the LBS positioning terminal of the personnel. The LBS positioning terminal receives and displays the abnormal work commencement alarm sent by the human error prevention decision system to remind the personnel that they are near a non-operational target in the same unit. At the same time, the LBS positioning terminal pops up an abnormal work commencement confirmation window, allowing the personnel to verify with the human error prevention decision system whether there is an abnormal work commencement.

[0083] c) If a person is stationed at an SPV device, but the device is not currently in operation, the human error prevention decision system sends a non-operational device alarm to the LBS positioning terminal of the person in operation. The LBS positioning terminal receives and displays the non-operational device alarm sent by the human error prevention decision system to remind the person in operation that the device is not in operation. At the same time, the LBS positioning terminal pops up a non-operational device confirmation window, allowing the person in operation to confirm with the human error prevention decision system whether any abnormalities have been found and whether there is any information that needs to be reported.

[0084] d) In non-extremely high-risk situations, when the human factors decision-making system confirms high risk to the construction personnel, if the construction personnel do not confirm the risk within the specified time, the human factors decision-making system will notify the operation personnel to carry out risk management based on the actual prefabrication plan.

[0085] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
