Description

Technical Field

[0001] The embodiments of the present application belong to the field of nuclear power technology, and in particular, relate to a method, device, and switchboard operating system for preventing human error in controlling a switchboard operating system of a nuclear power plant. Background Art

[0002] With the continuous improvement of the automation level of nuclear power plants, the application of distribution devices in nuclear power plants is becoming more and more extensive. The distribution device is mainly composed of a distribution board and an electric actuator plugged into the distribution board interface, which is used to receive electric energy from the power generation equipment in the nuclear power plant and distribute the electric energy to various electrical equipment or lower-level power grids. Among them, the electric actuator can be used to control the opening and closing state of a circuit on the distribution board, or to control related equipment on the distribution board (such as intelligent circuit breakers, contactors, etc.) to achieve the regulation and distribution of currents on different circuits in the distribution board. For example, when the staff of a nuclear power plant needs to control the connectivity of a circuit in the distribution board, the staff of the nuclear power plant can insert the electric actuator into the switch interface corresponding to the circuit, and switch the circuit from the open position to the closed position through the electric actuator to control the conduction of the circuit.

[0003] In order to ensure production safety, nuclear power plant staff need to regularly remove the electric actuator from the nuclear power plant's switchboard and send it to relevant laboratories for maintenance and debugging to ensure that the electric actuator can operate normally. After the maintenance and debugging work is completed, the nuclear power plant staff need to reinsert the electric actuator into the corresponding interface of the switchboard. In the prior art, since the electric actuator is compatible with all interfaces on the switchboard, the staff can directly insert the electric actuator into any interface of the switchboard. Furthermore, there are a large number of interfaces on the switchboard and they are arranged relatively closely, so it is easy for the staff to insert the electric actuator into the wrong interface, causing the staff to control the wrong circuit or equipment on the switchboard. Such misoperation caused by human factors can easily cause functional disorders of the distribution device and may even cause safety accidents, thereby threatening the production safety of the nuclear power plant and the stable operation of the equipment.

[0056] In the following description, specific details such as specific system structures, technologies, etc. are proposed for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also 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 hindering the description of the present application.

[0057] The technical solution of the present application is described below through specific embodiments.

[0058] At present, during the maintenance or testing of electric actuators on the switchboard, nuclear power plants have experienced many accidents due to the staff inserting the electric actuators into the corresponding interfaces of the switchboard in the wrong position, which led to the functional disorder of the switchboard. Figure 1 , shows a schematic diagram of a distribution board provided in an embodiment of the present application. Figure 1 As shown, there are multiple second interfaces closely arranged on the switchboard, so it is easy for the staff to insert the electric actuator into the wrong interface. For example, nuclear power plant A reported: After completing the annual inspection of electric actuator A, the staff needs to reinsert the electric actuator after the annual inspection into the corresponding interface of the switchboard. At this time, after the person in charge called out the votes according to the annual inspection list, the staff picked up the electric actuator, and then the staff mistakenly inserted the electric actuator that was originally connected to interface 207 into interface 208, causing nuclear power equipment B to lose the main control startup function for 13 seconds, during which nuclear power equipment B was performing fuel operations. If nuclear power equipment B suddenly stops at this time, the staff will be unable to control nuclear power equipment B to perform the main control startup, which may cause a safety accident in nuclear power equipment B, thereby threatening the production safety of the nuclear power plant.

[0059] See also Figure 2, shows a schematic diagram of a debugging process provided by an embodiment of the present application. Figure 2 As shown, in the existing technology, when the staff needs to debug the second interface on a distribution board in the electrical plant, the person in charge can first call out the first vote according to the debugging list corresponding to the current electrical plant. After the first call, the staff can hang a debugging operation sign at the door of the electrical plant. Then, the person in charge can start to call out the second interfaces to be debugged one by one according to the debugging list. After the person in charge calls out the location code of each second interface to be debugged, the staff can pick up the electric actuator corresponding to the second interface and insert the electric actuator into the second interface to be debugged.

[0060] Then, the staff can adjust and distribute the current on the circuit corresponding to the second interface through the electric actuator to debug the second interface. After the debugging is completed, the person in charge can vote on the next second interface to be debugged, and the staff can debug the next second interface to be debugged. Therefore, in the prior art, it is easy for the staff to insert the electric actuator into the wrong interface. In particular, when the number of interfaces to be debugged is greater than the number of available electric actuators (for example, the staff needs to debug 10 second interfaces, but there are only 5 electric actuators), the staff needs to cyclically plug and unplug the electric actuator, which leads to an increase in the number of operation steps and is more likely to plug in the wrong interface.

[0061] The embodiment of the present application aims to provide a switchboard operating system to fundamentally solve the risks caused by human errors. This is especially true for scenarios where a large number of electric actuators and / or the second interface on the switchboard need to be debugged. The switchboard operating system provided by the embodiment of the present application can prevent staff from inserting the electric actuator into the wrong interface, thereby avoiding the error of incorrect interface insertion caused by human factors, improving the safety and work efficiency of debugging work, and laying the foundation for subsequent intelligent and advanced productivity.

[0062] Among them, see Figure 3 , shows a schematic diagram of a switchboard operating system provided by an embodiment of the present application. Figure 3As shown, the switchboard operating system provided in this embodiment can be composed of multiple electric actuators, control devices and charging modules. Among them, the charging module can be composed of a charging component and a packaging component. The packaging component can be used to fix the control device and the electric actuator. The charging component can be used to charge the control device and the electric actuator. The size of the charging component can be less than or equal to 400 mm * 300 mm * 200 mm. The charging component can be used to charge the electric actuator and the control device. Exemplarily, the charging component can be a charging box, and when the staff places the electric actuator and the control device into the charging box, the charging box can automatically charge the electric actuator and the control device.

[0063] The control device is a small device that can communicate with the electric actuator via a wireless network. The control device may be provided with a data transmission component, a data storage component, a display component, a keyboard and a plurality of function keys. Among them, the size of the display component may be less than or equal to 10.1 inches, the screen ratio may be 16:9, and the length may be less than or equal to 22.4 centimeters. The display component may be used to display the received identification information. The user may also input the identification information of the second interface into the control device through the keyboard. The data transmission component on the control device may be used to transmit data with the terminal device and / or the electric actuator. Among them, the data transmission component may include a universal serial bus and a Bluetooth module. The data storage component may be used to store a task list and a permission list set by the user, and the storage capacity may be greater than or equal to 4 gigabytes.

[0064] The electric actuator may be provided with a camera, a first interface, a display component, a battery, a wireless relay drive component and a plurality of function buttons. The outer packaging of the electric actuator may use non-conductive materials such as industrial-grade plastics to prevent grounding in the event of a fault. Among them, the battery on the electric actuator may have a charging function, and the battery may last for 3 days or more, and the battery may take 6 hours to charge. The display component on the electric actuator may be used to display the first identification information extracted by the electric actuator and the power of the electric actuator. A lock component may also be provided at the first interface of the electric actuator. The lock component on the electric actuator is usually in a locked state. When the electric actuator determines that the first identification information of the second interface currently located meets the unlocking condition, the electric actuator will switch the lock component from the locked state to the unlocked state. The wireless relay drive component on the electric actuator may be used to execute the control instructions sent by the control device. The current allowed to pass through the wireless relay drive component may be 48 volts of direct current. The wireless relay drive component may have anti-interference performance for AC and DC signals, and its response time is less than 0.2 seconds.

[0065] The electric actuator may include multiple first interfaces of different models to match the second interfaces of different models of switchboards. The first interface on the electric actuator can be inserted into the second interface of the switchboard and has a lock to prevent it from falling off. The length, width and height of the electric actuator should not exceed 25 mm. For example, the electric actuator may include an ABB first interface and a Schneider first interface to match the corresponding second interface on the switchboard. Figure 4 , shows a schematic diagram of an interface model provided in an embodiment of the present application. Figure 4 (a) may be a schematic diagram of the second interface of the ABB model on the switchboard. Figure 4 (b) may be a schematic diagram of a second interface of a Schneider model on a distribution board.

[0066] See also Figure 5 , shows a schematic diagram of a usage scenario provided by an embodiment of the present application. Figure 5 As shown, when the lock assembly at the first interface on the electric actuator is in an unlocked state, the staff can insert the electric actuator into the second interface of the switchboard. Then, the staff can send a control instruction to the electric actuator through the control device to control the electric actuator to perform the operation corresponding to the control instruction. The operating environment of the switchboard operating system can be the operating environment of the switchboard in a nuclear power plant. The switchboard operating system can operate indoors at normal temperature and pressure. See Table 1 below, which shows an environmental information table of an ABB model switchboard provided in an embodiment of the present application.

[0072] Table 2

[0073] Reference Figure 6 , which shows a schematic diagram of a control method for preventing human errors provided by an embodiment of the present application. The method can be applied to Figure 3 The above control method may specifically include the following steps:

[0074] S601. In a process of controlling the electric actuator to move on the switchboard, the electric actuator obtains a first interface image of a second interface corresponding to a current position on the switchboard through a camera.

[0075] In this embodiment, when the staff needs to insert the electric actuator into a second interface of the switchboard, the staff can hold the electric actuator and move it on the switchboard. When the staff moves the electric actuator to the position of the second interface to be inserted, the staff can perform a selection operation on the identification button on the electric actuator. The electric actuator can respond to the user's selection operation on the identification button, start the camera on the electric actuator, and collect the first interface image of the second interface corresponding to the current position on the switchboard through the camera.

[0076] S602: The electric actuator inputs the first interface image into a preset image processing algorithm to determine first identification information corresponding to the second interface.

[0077] In this embodiment, after the electric actuator acquires the first interface image, it can input the first interface image into the image processing algorithm preset by the R&D personnel, so as to extract the first identification information corresponding to the second interface from the first interface image through the image processing algorithm. Exemplarily, the first identification information can be the position code corresponding to the second interface on the switchboard. The position code can be used to indicate the position of the second interface on the switchboard. Specifically, the position code is in various forms such as a QR code, a barcode, and an identification composed of specific letters and / or numbers. It should be noted that the image processing algorithm in the electric actuator can be any image processing algorithm known to those skilled in the art, and the embodiment of the present application is not used to specifically limit the image processing algorithm. Exemplarily, the image processing algorithm may include units such as an image preprocessing unit, a nameplate extraction unit, a feature extraction unit, and a character recognition unit. The image processing algorithm can recognize letters and / or numbers, and the number of recognized digits is at least 20 or more, and the recognition accuracy must reach 100%.

[0078] S603: If the first identification information corresponding to the second interface meets the unlocking condition, the electric actuator controls the lock assembly to change from a locked state to an unlocked state to allow the first interface of the electric actuator to be inserted into the second interface.

[0079] In this embodiment, after the electric actuator obtains the first identification information of the second interface at the location, it can determine whether the first identification information at the current location meets the unlocking condition. If the electric actuator determines that the first identification currently collected meets the non-unlocking condition, the electric actuator can maintain the locked state of the lock component unchanged and play the first prompt information through the voice broadcast component. Among them, the first prompt information is used to remind the staff that the second interface at the current location is an interface that is not allowed to be inserted. If the electric actuator determines that the first identification currently collected meets the unlocking condition, the electric actuator can play the currently recognized first identification information through the voice broadcast component and control the lock component at the first interface to change from a locked state to an unlocked state. After the lock component at the first interface is changed to an unlocked state, the staff can insert the electric actuator into the second interface at the current location.

[0080] After the electric actuator changes the lock assembly to the unlocked state, it can continue to detect the insertion event of the first interface. In the unlocked state of the lock assembly, if the electric actuator does not detect the insertion event of the first interface within a preset detection time, the electric actuator can change the lock assembly from the unlocked state to the locked state. If the electric actuator detects the insertion event of the first interface within the preset detection time, the electric actuator can maintain the unlocked state of the lock assembly unchanged.

[0081] Through the method provided in this embodiment, the electric actuator will switch to the unlocked state only when the first identification information of the second interface meets the unlocking condition. That is, only when the first identification information of the second interface meets the unlocking condition can the staff insert the electric actuator into the switchboard. Therefore, the method provided in this embodiment can ensure that the interfaces into which the electric actuator is inserted are all interfaces that the electric actuator is allowed to be inserted, thereby avoiding human errors that lead to incorrect insertion of the electric actuator, reducing the probability of accidents in the production process of the nuclear power plant, and thus improving the production safety of the nuclear power plant.

[0082] In one possible implementation, a permission list may be stored in the electric actuator. The permission list may include at least one second identification information. The second identification information stored in the permission list may be the identification information corresponding to the second interface that the staff allows the electric actuator to be inserted into. After the electric actuator obtains the first identification information corresponding to the second interface at the location, it may compare the first identification information with each second identification information in the permission list one by one. If the electric actuator determines that the first identification information matches any second identification information in the permission list, the electric actuator may determine that the current first identification information meets the unlocking condition, and the electric actuator may change the lock assembly from a locked state to an unlocked state. If the electric actuator determines that the first identification information does not match all the second identification information in the permission list, the electric actuator may determine that the current first identification information does not meet the unlocking condition, and the electric actuator may maintain the locked state of the lock assembly.

[0083] S604: During the process of the control device moving toward the target electric actuator, if the control device detects that the wireless signal strength of the target electric actuator is greater than a preset strength threshold, the control device establishes a second wireless link with the target electric actuator.

[0084] In this embodiment, a first near field communication (NFC) component may be provided on the electric actuator. After the electric actuator is inserted into the second interface of the switchboard, it can continuously send wireless signals to the outside through the first near field communication component. Among them, the wireless signal sent outward by the electric actuator may include communication information for establishing a wireless link with the electric actuator. After the staff inserts the electric actuator into the second interface of the switchboard, if the staff needs to control the circuit or related equipment on the switchboard through a certain electric actuator, the staff can hold the control device and continue to approach the target electric actuator that needs to be controlled.

[0085] A second near-field communication component may be provided on the control device. In the process of moving toward the target electric actuator, the second near-field communication component on the control device may continuously receive the wireless signal sent by the target electric actuator, and continuously determine whether the strength of the received wireless signal is greater than the strength threshold pre-set by the R&D personnel. If the control device determines that the wireless signal strength is greater than the strength threshold, for example, when the control device comes into contact with the target electric actuator, the control device may establish a second wireless link with the target electric actuator based on the communication information in the wireless signal, and display the identification information of the second interface where the target electric actuator is located through the display component on the control device. If the control device determines that the wireless signal strength is less than or equal to the strength threshold, the control device may not establish a second wireless link with the target electric actuator. Specifically, the transmission frequency band of the second wireless link may be an industrial frequency band, such as the 2.4 GHz Industrial Science Medicine (ISM) band. The data rate of the second wireless link may be 1 megabit per second. The second wireless link may use time division duplex transmission technology to achieve full-duplex transmission.

[0086] S605: In response to the control operation of the user, the control device sends a control instruction corresponding to the control operation to the target electric actuator through the second wireless link to control the target electric actuator to perform the operation corresponding to the control instruction.

[0087] In this embodiment, after the control device establishes a second wireless link with the target electric actuator, if the staff needs to control the target electric actuator to perform certain operations, the user can perform the corresponding control operation on the control device. In response to the user's control operation, the control device can send a control instruction corresponding to the control operation to the target electric actuator through the second wireless link to control the target electric actuator to perform the operation corresponding to the control instruction. The target electric actuator can perform the operation corresponding to the control instruction according to the received control instruction. Exemplarily, the control instructions sent by the control device may include but are not limited to instructions such as opening instructions, closing instructions, and keeping the gate open for three seconds.

[0088] In this embodiment, before the control device controls a certain electric actuator, it must first manipulate the control device to be close to the target electric actuator to be controlled, and then the control device can establish a second wireless link with the target electric actuator for transmitting control instructions. It can be seen that through the method provided by this embodiment, that is, the staff needs to manipulate the control device to touch the target electric actuator before establishing a wireless link between the control device and the target electric actuator each time. Therefore, the method provided by this embodiment can improve the accuracy of the staff's control of the target electric actuator and avoid the staff from mistakenly controlling other electric actuators when using the control device for remote control.

[0089] In one possible implementation, when a staff member needs to perform operations on multiple different second interfaces through multiple electric actuators in sequence, in order to ensure the accuracy of the operations performed by each electric actuator on the second interface, the staff member can first write a task list through a terminal device. Among them, the terminal device can be any device that can communicate with the control device, such as a computer, a tablet computer, a mobile terminal, etc. The task list can include the third identification information corresponding to each second interface that needs to be controlled and the operation instructions corresponding to each third identification information. Then, the staff member can send the task list to the control device through the communication link between the terminal device and the control device, such as a universal serial bus (USB). The control device can store the task list transmitted by the terminal device, and send control instructions to the electric actuators on each second interface according to the task list.

[0090] In a possible implementation, after the control device establishes a second wireless link with the target electric actuator, the developer can input the first identification information corresponding to the second interface where the target electric actuator is located into the control device through the keyboard on the control device. The control device can query the control instruction corresponding to the second interface from the task list according to the first identification information input by the user, and send the control instruction to the target electric actuator through the second wireless link.

[0091] In a possible implementation, a camera may also be provided on the control device. After the control device establishes a second wireless link with the target electric actuator, the R&D personnel may place the control device at the location of the target electric actuator and press the identification button on the control device at the same time. The control device may obtain a third interface image of the second interface where the target electric actuator is located through the camera in response to the user's selection of the identification button. Then, the control device may input the third interface image into the image processing algorithm to determine the first identification information corresponding to the second interface where the target electric actuator is located. After extracting the first identification information, the control device may query the control instruction corresponding to the second interface from the task list according to the extracted first identification information, and send the control instruction to the target electric actuator through the second wireless link.

[0092] Through the method provided in this embodiment, since the control device can automatically issue control instructions to the target electric actuator according to the task list pre-stored by the staff, the method provided in this embodiment can effectively prevent the staff from issuing erroneous instructions to the target electric actuator and improve the accuracy of the control instructions.

Figure 7, compared to Figure 6 In the embodiment, a control method for preventing human errors provided in the embodiment includes before S601: S701 to S706, which are described in detail as follows:

[0094] S701. The electric actuator obtains a second interface image of each second interface on the switchboard through a camera.

[0095] In this embodiment, when the staff needs to provide an electric actuator to establish a permission list corresponding to the electric actuator or needs to add additional second identification information to the permission list, the staff can hold the electric actuator and move it on the switchboard. When the electric actuator moves to the position where a second interface where the staff needs to insert the electric actuator is located, the staff can perform a selection operation on the acquisition button on the electric actuator. The electric actuator can respond to the staff's selection operation on the acquisition button and turn on the camera to obtain the second interface image corresponding to the second interface at the current location through the camera. The electric actuator can respond to the staff's multiple operations on the acquisition button to obtain the second interface image of each second interface on the switchboard.

[0096] S702: The electric actuator inputs each second interface image into an image processing algorithm to determine second identification information corresponding to each second interface image.

[0097] In this embodiment, after acquiring any second interface image, the electric actuator can input the currently acquired second interface image into the image processing algorithm to determine the second identification information corresponding to the second interface image through the image processing algorithm. The image processing algorithm in this embodiment is similar to the image processing algorithm in the first embodiment of the present application. For the specific content of the image processing algorithm, please refer to the first embodiment of the present application, which will not be repeated here.

[0098] S703: The electric actuator sends the pending review information including the second identification information to the control device in the switchboard operating system.

[0099] In this embodiment, after extracting the second identification information, the electric actuator can establish a first wireless link with the control device in the switchboard operating system, and send the pending review information containing the second identification information to the control device through the first wireless link.

[0100] S704: The control device receives the pending review information including the second identification information sent by any electric actuator.

[0101] In this embodiment, the control device can receive the pending information including the second identification information sent by the electric actuator through the first wireless link, and display the received pending information through the display component of the control device. After the control device displays the pending information, the staff can determine whether the second interface corresponding to the second identification information can be inserted by the electric actuator for control based on the second identification information in the pending information. If the second interface is not the target interface of the currently executed debugging project or the second interface is not the interface allowed to be inserted by the electric actuator, the staff can initiate a rejection operation to the control device. In response to the user's rejection operation, the control device can feedback the rejection information to the electric actuator that sent the pending information.

[0102] S705: In response to the user's confirmation operation, the control device sends confirmation information corresponding to the information to be reviewed to any one of the electric actuators.

[0103] In this embodiment, if the second interface is the target interface of the currently executed debugging project and / or the second interface is an interface that the electric actuator is allowed to be inserted into, the staff can initiate a confirmation operation to the control device. In response to the user's confirmation operation, the control device can feedback confirmation information to the electric actuator that sent the pending information through the first wireless link.

[0104] S706: If the electric actuator receives confirmation information fed back by the control device based on the information to be reviewed, the electric actuator writes the second identification information into the permission list.

[0105] In this embodiment, after the electric actuator sends the pending information to the control device, it can continuously receive information fed back by the control device through the first wireless link. If the electric actuator receives confirmation information fed back by the control device, the electric actuator can write the current second identification information into the permission list and display the confirmation information on the display component of the electric actuator. If the electric actuator receives rejection information fed back by the control device, the electric actuator can delete the second identification information and display the rejection information on the display component of the electric actuator.

[0106] Through the method provided in this embodiment, the staff can establish a permission list for unlocking judgment through the electric actuator. Therefore, the method provided in this embodiment can expand the use scenarios of the electric actuator, thereby improving the availability of the electric actuator and the convenience of the switchboard operating system during use.

[0107] Figure 8 FIG. 4 shows a specific implementation flow chart of a control method for preventing human errors provided in the third embodiment of the present application before S401. Figure 8 , compared to Figure 6In the embodiment, a control method for preventing human errors provided in the embodiment includes before S601: S801 to S803, which are described in detail as follows:

[0108] S801. The electric actuator establishes a first wireless link with a control device in a switchboard operating system in response to a user selecting a download button on the electric actuator.

[0109] In this embodiment, before the electric actuator makes an unlocking judgment on the first identification information, the staff needs to first establish a permission list corresponding to the electric actuator. At this time, the staff can perform a selection operation on the download button on the electric actuator to download the permission list pre-stored by the staff from the control device. The electric actuator can establish a first wireless link with the control device in response to the user's selection operation on the download button, and send a list acquisition request to the control device.

[0110] S802: The control device transmits the permission list input by the user to any electric actuator via a first wireless link between the control device and the electric actuator.

[0111] In this embodiment, the control device may receive a list acquisition request sent by the electric actuator through a first wireless link between the control device and the electric actuator, and in response to the received list acquisition request, send a permission list pre-stored by the user to the electric actuator that initiated the request.

[0112] In a possible implementation, when a staff member of a nuclear power plant needs to debug multiple second interfaces on a switchboard, the staff member can first establish a permission list through a terminal device. The permission list can include second identification information corresponding to all second interfaces that currently need to be debugged. Then, the staff member can send the permission list to the control device through a communication link between the terminal device and the control device.

[0113] In a possible implementation, the staff can also establish a permission list through the control device. Among them, a camera can be provided on the control device. When the staff needs to establish a permission list through the control device, the staff can move the control device on the switchboard with the handheld control device. When the control device moves to the location of the second interface that the staff needs to add to the permission list, the staff can perform a selection operation on the acquisition button on the control device. The control device can respond to the staff's selection operation on the acquisition button and obtain the fourth interface image corresponding to the second interface at the current location through the camera on the control device. Then, the control device can input the fourth interface image into the image processing algorithm to extract the second identification information corresponding to the fourth interface image. The control device can display the extracted second identification information through the display component on the control device. If the staff determines that the second identification information is correct, the staff can initiate a confirmation operation to the control device. The control device can write the second identification information into the permission list in response to the confirmation operation. If the staff determines that the second identification information is incorrect, the staff can initiate a rejection operation to the control device. The control device can delete the second identification information in response to the rejection operation.

[0114] S803: The electric actuator receives the permission list through the first wireless link and stores the permission list.

[0115] In this embodiment, after establishing the first wireless link with the control device, the electric actuator can continuously receive the permission list sent by the control device through the first wireless link, and store the received permission list to determine whether the first identification information of the second interface on the distribution board meets the unlocking condition based on the second identification information in the permission list.

[0116] Through the method provided in this embodiment, the electric actuator can obtain the permission list preset by the user from the control device for unlocking judgment. Therefore, the method provided in this embodiment allows the staff to construct the permission list in multiple ways, thereby improving the usability of the switchboard operating system.

[0117] It should be noted that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
