[0022] The method and device for determining a maintenance route in a factory according to an embodiment of the present specification will be described in detail below with reference to the accompanying drawings.

[0023] Figure 1 An exemplary architecture 100 of a method and apparatus for determining a maintenance route within a plant according to an embodiment of the present specification is shown.

[0024] exist Figure 1 In the embodiment, the network 110 is used to interconnect the terminal device 120 and the application server 130 .

[0025] The network 110 may be any type of network capable of interconnecting network entities. The network 110 may be a single network or a combination of various networks. In terms of coverage, the network 110 may be a local area network (LAN), a wide area network (WAN), etc. In terms of carrier media, the network 110 may be a wired network, a wireless network, etc. In terms of data exchange technology, the network 110 may be a circuit switching network, a packet switching network, etc.

[0026] The terminal device 120 may be any type of electronic computing device that can connect to the network 110, access a server or website on the network 110, process data or signals, etc. For example, the terminal device 120 may include various electronic devices (such as smart phones, etc.) used by maintenance personnel. For another example, the terminal device 120 may be an intelligent inspection robot. Figure 1 Only one terminal device is shown in FIG. 1 , but it should be understood that a different number of terminal devices may be connected to the network 110 .

[0027] In one example, the application server 130 may be connected to the central control system 140. The central control system 140 may be connected to various sensors provided in the factory. In one example, when the reading of the sensor connected to the central control system 140 is abnormal, the generation of maintenance task information may be triggered. The application server 130 may obtain the generated maintenance task information from the central control system 140.

[0028] It should be understood that Figure 1All network entities shown in the figure are exemplary. Any other network entities may be involved in the architecture 100 according to specific application requirements.

[0029] Figure 2 A flow chart of a method 200 for determining a maintenance route within a plant according to an embodiment of the present specification is shown.

[0030] like Figure 2 As shown, at 210, maintenance task information is obtained.

[0031] In this embodiment, the maintenance task information may include task content, task urgency information, and task location information. Task urgency information may be used to indicate whether it is urgent. Task location information may be used to indicate the location of the task. Task content may be used to match callable maintenance resources. In one example, maintenance task information may be obtained from an Advanced Planning and Scheduling (APS) system, and the maintenance task information may be, for example, information indicating a non-urgent task of regularly replacing or maintaining the bearing of a device located in Area B of a chemical plant and having a position number of XXX. In one example, the maintenance task information may also be information indicating a non-urgent task of solving a dripping problem that does not affect normal operation and does not pollute the environment in a mechanical seal of a device located in Area F of a chemical plant and having a position number of XXXX, which is discovered and recorded during an on-site inspection. In one example, maintenance task information may be obtained from a central control system, and the maintenance task information may be, for example, information indicating an urgent task that a certain elbow of a device located in Area M of a chemical plant and having a position number of YYY has a leak due to erosion corrosion and needs to be promptly handled. In an example, the maintenance task information may also be information indicating an urgent task to replace or maintain the bearing of a device located in area L of a chemical plant and having a position number of YYYY.

[0032] At 220 , available maintenance resource information matching the maintenance task information is obtained.

[0033] In this embodiment, the callable maintenance resource information can match at least one of the task content, task urgency information and task location information in the maintenance task information. In one example, the callable maintenance resource information can be used to indicate the callable maintenance resources. Among them, the maintenance resources can include, for example, at least one of maintenance personnel and intelligent inspection robots. In one example, the maintenance resources can correspond to maintainable content and maintainable range. Among them, the maintainable content can be used to indicate the maintenance tasks that can be completed. For example, different types of work can correspond to different maintainable contents. The maintainable range can be used to indicate the location that the maintenance resources can reach. Optionally, in one example, the maintenance resources can also correspond to the current idle state and the maintenance plan. Among them, the maintenance plan corresponding to the maintenance resource can be obtained from the scheduling system, for example.

[0034] In one example, the callable maintenance resources can be determined from the maintenance resources based on the match between the maintainable content and the task content. In one example, the callable maintenance resources can be determined from the maintenance resources based on the match between the maintainable scope and the task location indicated by the task location information. In one example, for non-urgent maintenance tasks, the callable maintenance resources can be determined from the maintenance resources based on the current idle state and the maintenance plan. In one example, for urgent maintenance tasks, all maintenance resources that meet the requirements of the maintainable content and the maintainable scope can be determined as callable maintenance resources.

[0035] At 230 , it is determined whether the task urgency information indicates urgency.

[0036] If the judgment is yes, at 240, a maintenance route is determined based on the task location information and the current location of the callable maintenance resource indicated by the callable maintenance resource information, so that the callable maintenance resource arrives at the task location corresponding to the maintenance task information within the time limit constraint corresponding to the maintenance task information.

[0037] In this embodiment, for an emergency maintenance task, the time limit constraint corresponding to the maintenance task information can be first obtained. In one example, the correspondence between the task content and the time limit constraint can be obtained in advance. For example, for a task to deal with an abnormal pressure gauge reading that affects operational safety, the time limit constraint is to arrive at the task location within 2 hours. In one example, if the maintenance task information indicates predictive maintenance, such as predicting that the bearing will be damaged in the next week, the time limit constraint can be to complete the replacement within 3 days.

[0038] In one example, various path planning methods can be used to determine a route starting from the current location of the available maintenance resources indicated by each available maintenance resource information and ending at the task location indicated by the above task location information. It can then be determined whether the time corresponding to the above shortest route meets the time limit constraint corresponding to the above maintenance task information. In one example, the time limit constraint corresponding to the maintenance task information can also be related to the number of available maintenance resources performing the maintenance task. For example, for maintenance task X, the arrival time limit constraint corresponding to the task performed by 3 maintenance personnel is 2 hours; the arrival time limit constraint corresponding to the task performed by 5 maintenance personnel is 3 hours. Thus, it can also be determined that the previous N Whether the time consumption corresponding to the longest route among the shortest routes meets the time limit constraint corresponding to the above maintenance task information.

[0039] If the determination is no, at 250 , a maintenance route is determined according to the maintenance points involved in the maintenance plan corresponding to the task location information and the available maintenance resource information.

[0040] In this embodiment, for non-emergency maintenance tasks, the maintenance route can be determined in combination with the maintenance points and task location information involved in the maintenance plan corresponding to the callable maintenance resource information. In one example, the corresponding callable maintenance resources and the corresponding maintenance route can be determined with the goal of adding the task location indicated by the task location information to the corresponding maintenance plan with the shortest distance added. For example, if the location indicated by the task location information is close to the maintenance point involved in a maintenance plan for the next day by a maintenance personnel, the maintenance route can be determined by combining the maintenance point corresponding to the maintenance plan for the next day with the task location.

[0041] Optionally, for non-emergency maintenance tasks, the maintenance route can also be determined by combining the maintenance points involved in the maintenance plan corresponding to the callable maintenance resource information, the task location information, and the avoidance area and / or the corresponding waypoints corresponding to the non-emergency maintenance task. Optionally, the specific determination process of the maintenance route can refer to the corresponding description of the avoidance area and waypoints below, which will not be repeated here.

[0042] Reference below Figure 3 , Figure 3 A flowchart showing yet another example of a method for determining a maintenance route within a plant according to an embodiment of the present specification.

[0043] At 310 , maintenance task information is obtained.

[0044] In this embodiment, the maintenance task information may include task content, task urgency information and task location information. The task urgency information may be used to indicate whether it is urgent.

[0045] Optionally, in one example, the maintenance task information may also include device abnormality information for indicating an abnormal event targeted by the maintenance task. In one example, the device abnormality information may be used to indicate that a certain pressure gauge reading is abnormally high. In one example, the device abnormality information may be used to indicate that a certain mechanical seal device is leaking. In one example, the device abnormality information may be used to indicate that a certain bearing is vibrating too high during vibration measurement. In one example, the device abnormality information may be used to indicate that a certain pipeline is damaged and leaks.

[0046] At 320 , available maintenance resource information matching the maintenance task information is obtained.

[0047] At 330 , it is determined whether the task urgency information indicates urgency.

[0048] If the answer at step 330 is yes, the following steps 341-349 are executed.

[0049] At 341 , current avoidance area information corresponding to the maintenance task information is acquired.

[0050] In this embodiment, the current avoidance area information can be used to indicate the area that needs to be avoided in the maintenance route. In one example, the current avoidance area information can correspond to the callable maintenance resource information. For example, maintenance personnel A, B, and C can respectively select corresponding areas as their respective avoidance areas, so as to obtain the current avoidance area information corresponding to the maintenance task information.

[0051] Optionally, continue to refer to Figure 4 , Figure 4 A flowchart of an example of a process 400 for obtaining current avoidance area information according to an embodiment of the present specification is shown.

[0052] like Figure 4 As shown, at 410, risk point information related to the maintenance task information and safety protection information corresponding to the callable maintenance resources are obtained.

[0053] In this embodiment, risk point information can be used to indicate risky points in the factory. In one example, the above risks may include but are not limited to at least one of the following: dust, noise, electric shock, mechanical injury, poisoning, and object impact. The callable maintenance resources may correspond to the corresponding safety protection information. The safety protection information can be used to indicate the protective measures that can be adopted by the callable maintenance resources. In one example, the above protective measures may include but are not limited to at least one of the following: wearing a dust mask, wearing earplugs, wearing anti-smashing insulating shoes, wearing protective gloves, wearing anti-insulating gloves, wearing a gas mask, wearing a safety helmet, etc.

[0054] At 420 , according to the matching between the risk point information and the corresponding safety protection information, the current avoidance area information corresponding to the maintenance task information is determined.

[0055] In one example, the avoidance area can be determined based on the risk points indicated by the risk point information for which there is no matching safety protection information, and then the current avoidance area information can be generated. For example, the risk point information is used to indicate the existence of noise, electric shock, and poisoning risks, and the corresponding safety protection information corresponding to the callable maintenance resources is used to indicate wearing earplugs and wearing a gas mask, so the current avoidance area information for indicating avoiding areas with electric shock risks can be generated.

[0056] In one example, different callable maintenance resources may correspond to different security protection information, so that the current avoidance area information corresponding to each callable maintenance resource may be obtained.

[0057] Based on this, this solution can determine the current avoidance area information by matching the determined risk point information with the corresponding safety protection information, thereby helping to improve the accuracy of the current avoidance area information.

[0058] Optionally, continue to refer to Figure 5 , Figure 5 A flowchart showing another example of a process 500 for obtaining current avoidance area information according to an embodiment of the present specification.

[0059] like Figure 5 As shown, at 510, a three-dimensional plant model corresponding to the maintenance task information is acquired.

[0060] In one example, a portion corresponding to the task location indicated by the maintenance task information may be extracted from the three-dimensional plant model. For example, a three-dimensional plant model within a range not exceeding a preset distance from the task location may be extracted. In one example, the three-dimensional plant model may include the location of each device and the association relationship between the devices.

[0061] At 520 , the impact point corresponding to the device abnormality information is determined according to the three-dimensional plant model.

[0062] In one example, the corresponding impact point can be determined based on the various devices and their associations associated with the device abnormality information indicated by the three-dimensional plant model. Among them, the impact point can refer to the equipment or corresponding device whose state changes accordingly. For example, if the pressure gauge reading on a valve located on device X exceeds the warning threshold, the other valves connected to it through the pipeline can be determined as the corresponding impact point. For another example, if a circuit breaker located on a certain line trips, other circuit breakers (such as backup circuit breakers) with corresponding action relationships can be determined as corresponding impact points.

[0063] At 530 , a corresponding avoidance area is determined according to the determined impact point.

[0064] In an example, an area within a certain range from the determined influencing point may be determined as the avoidance area corresponding to the influencing point.

[0065] At 540, the determined avoidance area is provided to the verification end.

[0066] In this embodiment, the verification terminal may be a terminal for confirming the determined avoidance area. In one example, the verification terminal may be a terminal used by a management personnel. In one example, the verification terminal may be a terminal used by a callable maintenance personnel. In one example, the determined avoidance area may be provided to the verification terminal, and the determined avoidance area may include, for example, pre-divided areas A1, A8, and A9 (not shown in the figure) in the factory.

[0067] At 550, current avoidance area information corresponding to the maintenance task information is generated according to the information fed back by the verification end.

[0068] In this embodiment, the information fed back by the verification end may include the result of confirming each determined avoidance area. In one example, the information fed back by the verification end may be used to indicate the confirmation of the avoidance area (e.g., area A1, A9) and the exclusion of area A8 from the avoidance area. Afterwards, the current avoidance area information corresponding to the maintenance task information may be generated according to the information fed back by the verification end, such as information indicating the avoidance areas A1, A9.

[0069] Based on this, this solution can predict the impact points corresponding to the maintenance tasks through the three-dimensional factory model, and obtain more accurate current avoidance area information through further confirmation at the verification end.

[0070] Back to Figure 3 At 343, an alternative maintenance route is determined according to the task location information, the corresponding current avoidance area information, and the current location of the available maintenance resource indicated by the available maintenance resource information.

[0071] In one example, various path planning methods may be used to determine a route that takes the current location of the available maintenance resource indicated by each available maintenance resource information as a starting point, takes the task location indicated by the above task location information as an end point, and avoids passing through the area indicated by the corresponding current avoidance area information as an alternative maintenance route. Optionally, different available maintenance resource information may correspond to different current avoidance area information.

[0072] At 345 , it is determined whether the determined candidate maintenance route satisfies the time limit constraint corresponding to the maintenance task information.

[0073] In this embodiment, the maintenance task information may correspond to a time limit constraint. In one example, different task contents and task urgency may correspond to different time limit constraints. For example, for a line trip, the corresponding time limit constraint may be that a certain number of maintenance personnel arrive at the location of the incident within 1 hour.

[0074] In one example, it may be determined whether the time taken for each available maintenance resource to arrive at the task location satisfies the corresponding time limit constraint according to the candidate maintenance route and the corresponding predetermined speed corresponding to each available maintenance resource.

[0075] If the determination at 345 is yes, at 347 , the candidate maintenance route is determined as the maintenance route.

[0076] If the determination at step 345 is negative, at step 349 , the current avoidance area information is updated.

[0077] In this embodiment, the current avoidance area information can be updated to reduce the avoidance area. In one example, the current avoidance area information that originally indicated the avoidance area within 30 meters from the risk point can be updated to indicate the current avoidance area information within 20 meters from the risk point. In one example, the area where the risk can be reduced by safety protection measures can be excluded from the current avoidance area to update the current avoidance area information.

[0078] In this embodiment, after the current avoidance area information is updated, the process may return to step 343 to continue execution.

[0079] Optionally, continue to refer to Figure 6 , Figure 6 FIG. 6 is a flowchart showing an example of a process 600 for updating current avoidance area information according to an embodiment of the present specification.

[0080] like Figure 6 As shown, at 610, an estimated arrival time is determined based on the determined alternative maintenance route.

[0081] In one example, the estimated arrival time of each available maintenance resource at the task location may be determined according to the candidate maintenance route and the corresponding predetermined speed corresponding to each available maintenance resource.

[0082] At 620 , the impact point corresponding to the device abnormality information is updated according to the three-dimensional plant model and the estimated arrival time.

[0083] In this embodiment, the impact point corresponding to the device abnormality information can be updated according to the three-dimensional plant model and the estimated arrival time. In one example, the impact of the abnormal event corresponding to the maintenance task can be predicted according to the three-dimensional plant model, so as to obtain the impact point corresponding to the estimated arrival time as the impact point corresponding to the updated device abnormality information. For example, for the abnormal event of pipeline leakage, its impact area usually expands over time.

[0084] At 630 , a corresponding candidate avoidance area is determined according to the updated impact point.

[0085] At 640, the determined candidate avoidance area is provided to the verification end.

[0086] At 650, the current avoidance area information is updated according to the information fed back by the verification end.

[0087] It should be noted that the operations of the above steps 630-650 can refer to the above Figure 5 The description of steps 530-550 in the embodiment will not be repeated here.

[0088] Based on this, this solution can update the impact points corresponding to the device abnormality information according to the estimated arrival time, and then update the current avoidance area information, thereby taking into account the impact of the time dimension on the current avoidance area and further improving the accuracy of the current avoidance area information.

[0089] Back to Figure 3 If the judgment at 330 is no, at 350, a maintenance route is determined according to the maintenance points involved in the maintenance plan corresponding to the task location information and the available maintenance resource information.

[0090] It should be noted that the operations of steps 320-330 and 350 can refer to the aforementioned Figure 2 The descriptions of steps 220 - 230 and 250 in the embodiment are not repeated here.

[0091] Based on this, this solution can combine the current avoidance area information corresponding to the maintenance task information and the corresponding time limit constraints for route planning, which is particularly suitable for application scenarios involving risk areas within the factory.

[0092] Reference below Figure 7 , Figure 7 A flowchart of yet another example of a method 700 for determining a maintenance route within a plant according to an embodiment of the present specification is shown.

[0093] At 710, maintenance task information is obtained.

[0094] In this embodiment, the maintenance task information may include task content, task urgency information, and task location information. The task urgency information may be used to indicate whether it is urgent. The maintenance task information may also include device abnormality information for indicating the abnormal event targeted by the maintenance task.

[0095] At 720 , available maintenance resource information matching the maintenance task information is obtained.

[0096] At 730 , it is determined whether the task urgency information indicates urgency.

[0097] It should be noted that the operations of the above steps 710-730 can refer to the above Figure 2 The description of steps 210-230 in the embodiment will not be repeated here.

[0098] If the judgment at 730 is yes, execute the following steps 741-743.

[0099] At 741, waypoint information corresponding to the maintenance task information is acquired according to the device abnormality information.

[0100] In this embodiment, the waypoint information can be used to indicate the necessary points of the determined maintenance route. In one example, the waypoint information can be used to indicate the location of the tools or protective equipment required to complete the task indicated by the above maintenance task information. In one example, the waypoint information can be used to indicate the location of the spare parts required to complete the task indicated by the above maintenance task information.

[0101] At 743, a maintenance route is determined based on the task location information, the corresponding waypoint information, and the current location of the callable maintenance resource indicated by the callable maintenance resource information, so that the callable maintenance resource arrives at the task location corresponding to the maintenance task information within the time limit constraint corresponding to the maintenance task information.

[0102] In one example, various path planning methods may be used to determine a route with the current location of the callable maintenance resource indicated by each callable maintenance resource information as the starting point, the task location indicated by the task location information as the end point, and the waypoints indicated by the waypoint information corresponding to the waypoints as the maintenance route. Optionally, different callable maintenance resource information may correspond to different waypoint information.

[0103] It should be noted that the operation of the time limit constraint in the above step 743 can refer to the above Figure 2 The relevant description of step 250 in the embodiment will not be repeated here.

[0104] Optionally, the callable maintenance resource may include at least two callable maintenance resources. At least two maintenance routes may be determined based on the task location information, the corresponding waypoint information, and the current location of the callable maintenance resource indicated by the callable maintenance resource information. The at least two maintenance routes may include at least a first maintenance route and a second maintenance route. The first maintenance route may be used to indicate the route from the current location of at least one callable maintenance resource through the corresponding waypoint and the meeting point to the task location. The second maintenance route may be used to indicate the route from the current location of at least one callable maintenance resource through the meeting point to the task location.

[0105] In one example, Figure 8 FIG. 8 is a schematic diagram showing another example application scenario of a method 800 for determining a maintenance route within a factory according to an embodiment of the present specification. Figure 8 As shown, if the maintenance task information is used to indicate an emergency task at location 0. The maintenance resource information that matches the maintenance task information (for example, the maintenance resource information indicating maintenance resources 2, 3, 4) can be selected from the maintenance resource information used to indicate maintenance resources 1, 2, 3, 4 as the maintenance resource information that can be called. Affected by the emergency task, there are risk areas 5 and 6, and the corresponding required protective tools are placed at location 7. Thus, the waypoint information indicating location 7 and location 8 as the meeting point can be obtained. Furthermore, the first maintenance route for indicating that the maintenance resource 4 reaches the meeting point 8 from the current position via the location 7 indicated by the waypoint information and meets with the maintenance resources 2 and 3, and then continues to go to location 0; and the second maintenance route for indicating that the maintenance resources 2 and 3 meet with the maintenance resource 4 from their respective current positions via the meeting point 8 and then go to location 0 together.

[0106] Back to Figure 7 If the judgment at 730 is no, at 750, a maintenance route is determined according to the maintenance points involved in the maintenance plan corresponding to the task location information and the available maintenance resource information.

[0107] It should be noted that the operation of the above step 750 can refer to the above Figure 2 The relevant description of step 250 in the embodiment will not be repeated here.

[0108] Optionally, step 760 may be further executed to send a corresponding maintenance roadmap to a client corresponding to each callable maintenance resource.

[0109] In this embodiment, the above maintenance route map can be generated based on the determined maintenance route and the three-dimensional plant model. In one example, the maintenance routes corresponding to the various callable maintenance resources obtained can be embedded in the three-dimensional plant model for display. Optionally, avoidance areas, waypoints, etc. can be distinguished and marked in the three-dimensional plant model (for example, using red areas, green marks, etc.). Optionally, areas involving safety protection measures in the maintenance route are highlighted in the three-dimensional plant model, and safety prompt information (such as wearing a helmet, etc.) is displayed at the same time.
