Description

Technical Field

[0001] The present invention relates to the technical field of civil aviation airport safety, and in particular to a hierarchical emergency disposal system and method for apron oil supply pipe network equipment. Background Art

[0002] At present, the domestic apron fuel supply pipeline network lacks information management methods. For emergency response, it is often necessary to arrange emergency response plans in advance, conduct desktop exercises and actual combat exercises on emergency plans, and optimize the contents of the plans according to the problems that arise.

[0003] However, the logic of the pipeline network of the apron fuel supply equipment is complex. While mastering the operating skills, the most important thing is to accurately close the corresponding valves, which is a difficult task for personnel with insufficient experience and short working time. In addition, if an emergency occurs, personnel with little working experience are prone to nervousness, panic, and other problems, and make mistakes in operation.

[0004] In addition, the parking position is the location for the aircraft to dock, and each parking position will correspond to a refueling hydrant, which will be used to refuel the aircraft through a refueling truck. Therefore, when the refueling hydrant fails or the equipment in the pipe section fails, the parking position corresponding to the failed refueling hydrant cannot provide fuel to the aircraft.

[0005] Therefore, there is a need for a hierarchical emergency response system and method for apron fuel supply network equipment that can shorten emergency operation preparation time and response time, improve the accuracy of emergency response, and avoid affecting apron safety due to emergency situations. Summary of the invention

[0006] In order to solve the problem that the existing emergency response methods can only carry out emergency management after the on-site risk has occurred, or complete the corresponding emergency response through emergency equipment, and cannot be applied to the situation of multi-department coordination and management of civil airports. If a complex risk level calculation formula is used, it is impossible for all relevant personnel to make the same emergency management method. The present invention provides a hierarchical emergency response system and method for apron oil supply pipeline equipment that can shorten the emergency operation preparation time and response time, improve the accuracy of emergency response, and avoid the apron safety being affected due to emergency situations.

[0007] The hierarchical emergency disposal method for apron oil supply pipe network equipment of the present invention comprises the following steps:

[0008] S1. Establish preset tasks; establish emergency operation valve operation logic table for valves and equipment based on historical information and operation site, and divide emergency levels according to leakage point failure conditions; determine preset information transmission process and tasks to be performed under different emergency levels;

[0009] S2, tasks are divided by roles;

[0010] S21. Configure the operation roles: configure the roles according to different execution tasks, including the oil leakage monitoring module, the task matching module and the task execution module;

[0011] The oil leakage monitoring module monitors the on-site equipment in real time and reports the monitoring results to the task matching module when oil leakage occurs;

[0012] The task matching module matches the corresponding tasks according to the reported monitoring results and sends them to the on-site task execution module;

[0013] The task execution module closes the corresponding equipment or valve according to the task execution;

[0014] S22. Emergency response;

[0015] When the oil leakage monitoring module detects oil leakage from the equipment, it first determines whether the equipment itself or the maintenance valve is allowed to be closed, and reports the on-site situation to the task matching module;

[0016] S23. Release the emergency measures; restore the equipment and / or valves to normal status according to the emergency level;

[0017] S24. Make a task list;

[0018] According to the apron operation knowledge base, apron operation safety risk base, emergency operation valve operation logic table, emergency level, operation process, operation role configuration, emergency response process and emergency response release process, determine the task list of different roles.

[0019] Further: In S1, the specific steps of establishing the preset task are:

[0020] S11. Establishing a knowledge base for apron operations, which includes confined space operation requirements, apron operation requirements, apron operation content instructions, personnel division of labor and personnel authority, and clarifying the operating procedures and operation contents of personnel under different oil spill conditions;

[0021] S12. Establish a safety risk database for apron operations, and divide safety risks into operation risks, personnel risks, driving risks and environmental risks according to the operation contents;

[0022] S13. Determine the logic table for emergency operation valve operation. According to the pipeline network drawings, the apron oil supply pipeline network is divided into the smallest units based on the valves on the pipeline network. Closing the valve on the smallest unit can shut off the oil in the current pipeline section and isolate it from the external pipeline section. In this way, the valve that needs to be operated when the equipment on each unit fails is determined; at the same time, the equipment that will be affected after closing the valve is determined;

[0023] S14. Classify the emergency level according to the leakage point failure situation: The emergency situation includes three levels:

[0024] Level 3 response is when the equipment itself allows closure or the connected maintenance valve allows emergency closure;

[0025] The second-level response is when the equipment itself or the connected maintenance valves are not allowed to be closed in an emergency, but the upstream and downstream valves are allowed to be closed;

[0026] Level 1 response is when the equipment itself and the connected maintenance valves are not allowed to be closed in an emergency, and the upstream and downstream valves are not allowed to be closed;

[0027] S15. Determine the information transmission process under different emergency levels; based on the responsibilities and work scope of different units and departments, preset the information transmission process, and configure the key nodes and transmitters of information transmission.

[0028] Further: The specific process of matching tasks according to the on-site situation is:

[0029] If the equipment itself and the maintenance valve are both allowed to be closed, the third-level response is initiated, that is, the task execution module closes the equipment and the maintenance valve, and notifies the maintenance personnel to arrive at the site to repair the valve and deal with the oil leak;

[0030] If the equipment itself and the maintenance valve are not allowed to be closed, but the upstream and downstream valves are allowed to be closed, the secondary response is initiated, that is, the task execution module closes the upstream and downstream valves and notifies the relevant units that the equipment of the corresponding pipe section is temporarily unavailable;

[0031] For the second-level response, the duty commander and the on-site disposal personnel go to the operation site to deal with it and close the upstream and downstream valves of the corresponding pipe section. After the second-level emergency is initiated, if the on-site disposal personnel rush to the scene and still cannot control the situation, and the corresponding valve fails and cannot be closed, the commander will determine whether to upgrade to the first-level response. If upgrading is required, the superior person in charge will be notified;

[0032] The superior person in charge notifies the oil depot to take first-level response measures and notifies relevant units to prepare to stop the oil supply; after receiving the first-level response disposal task, the task execution module takes pump stop measures to stop the oil supply.

[0033] Further: the specific process of restoring the normal state of the equipment and / or valve according to the emergency level is as follows: for a level 3 emergency, when the on-site disposal personnel rush to the site for repair and the equipment is restored to normal, the task execution module opens the equipment and valve according to the information fed back by the on-site disposal personnel, and restores the use of the equipment and valve;

[0034] For the secondary emergency, when the on-site disposal personnel rush to the site for repair and the equipment returns to normal, the task execution module opens the upstream and downstream valves according to the information fed back by the on-site disposal personnel, and all the equipment in the pipe sections corresponding to the upstream and downstream valves are restored to use;

[0035] For a first-level emergency, when the on-site personnel rush to the site to complete the repairs and the equipment returns to normal, the task execution module restores the oil supply from the oil depot according to the instructions of the superior person in charge and notifies the relevant units that all equipment has returned to normal use.

[0036] The hierarchical emergency response system for apron oil supply pipe network equipment described in the present invention comprises an information display module, an equipment maintenance module, and an emergency response module;

[0037] The information display module is used to display the real-time status and operation status of the equipment; the real-time status of the equipment includes the current opening and closing status, emergency level status and current location;

[0038] The equipment maintenance module includes an oil leakage monitoring module and a reporting module, wherein the oil leakage monitoring module is used to monitor the real-time status of the equipment and the pipeline network in real time;

[0039] The emergency handling module is used to execute or release the closure of corresponding equipment or valves according to the task.

[0040] Furthermore: a QR code or NFC patch is set on the equipment. When the inspection personnel find oil leakage, they can report the fault of the current equipment by scanning the QR code with a mobile terminal or placing the mobile terminal close to the NFC patch.

[0041] Furthermore: the valve includes a refueling hydrant, a valve well, a high-point exhaust valve and / or a low-point sinking valve.

Any changes or substitutions that can be easily thought of by a technician familiar with the technical field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. The embodiments described below are only used to explain the present invention and cannot be interpreted as limitations on the present invention. The protection scope of the present invention should be based on the protection scope of the claims. The embodiments of the present invention are described in detail below. In order to facilitate the description of the present invention and simplify the description, the technical terms used in the specification of the present invention should be interpreted in a broad sense, including but not limited to conventional replacement schemes not mentioned in this application, and also including direct implementation methods and indirect implementation methods.

[0049] Example 1

[0050] Combination Figure 1-Figure 4 To explain this embodiment, this embodiment discloses a hierarchical emergency response method for apron fuel supply network equipment. The emergency response operations of the apron fuel supply equipment include special operations (i.e. confined spaces) and apron operations. Therefore, at the beginning of setting up the emergency plan, comprehensive consideration is given to the contents that need to be involved.

[0051] like Figure 3 and Figure 4 As shown in the figure, the apron oil supply network of civil airports is mainly composed of network valves and auxiliary equipment. The on-off of oil products in the network can be controlled by valves in sections; for auxiliary equipment, they usually have their own closing devices or maintenance valves, so that when equipment fails, the front-end valves can be closed for maintenance or replacement. Therefore, in addition to closing the valves themselves, the oil leakage of equipment on the network can also be controlled by closing the upstream and downstream valves of the pipe section.

[0052] like Figure 2 As shown, the embodiment discloses a hierarchical emergency response method of a hierarchical emergency response system for apron fuel supply pipe network equipment, comprising the following steps:

[0053] S1. Establish preset tasks; establish emergency operation valve operation logic table for valves and equipment based on historical information and operation site, and divide emergency levels according to leakage point failure conditions; determine preset information transmission process and tasks to be performed under different emergency levels;

[0054] The specific steps of establishing the preset task are:

[0055] S11. Establishing a knowledge base for apron operations, which includes confined space operation requirements, apron operation requirements, apron operation content instructions, personnel division of labor and personnel authority, and clarifying the operating procedures and operation contents of personnel under different oil spill conditions;

[0056] S12. Establish a safety risk database for apron operations, and divide safety risks into operation risks, personnel risks, driving risks and environmental risks according to the operation contents;

[0057] S13. Determine the logic table for emergency operation valve operation. According to the pipeline network drawings, the apron oil supply pipeline network is divided into the smallest units based on the valves on the pipeline network. Closing the valve on the smallest unit can shut off the oil at the end of the pipe and isolate it from the external pipe section. In this way, the valve that needs to be operated when the equipment on each unit fails is determined; at the same time, the equipment that will be affected after closing the valve is determined;

[0058] S14. Classify the emergency level according to the leakage point failure situation: The emergency situation includes three levels:

[0059] Level 3 response is when the equipment itself allows closure or the connected maintenance valve allows emergency closure;

[0060] The second-level response is when the equipment itself or the connected maintenance valves are not allowed to be closed in an emergency, but the upstream and downstream valves are allowed to be closed;

[0061] Level 1 response is when the equipment itself and the connected maintenance valves are not allowed to be closed in an emergency, and the upstream and downstream valves are not allowed to be closed;

[0062] S15. Determine the information transmission process under different emergency levels; based on the responsibilities and work scope of different units and departments, preset the information transmission process, and configure the key nodes and transmitters of information transmission.

[0063] S2, tasks are divided by roles;

[0064] S21. Configure the operation roles: configure the roles according to different execution tasks, including the oil leakage monitoring module, the task matching module and the task execution module;

[0065] The oil leakage monitoring module monitors the on-site equipment in real time and reports the monitoring results to the task matching module when oil leakage occurs;

[0066] The task matching module matches the corresponding tasks according to the reported monitoring results and sends them to the on-site task execution module;

[0067] The task execution module closes the corresponding equipment or valve according to the task execution;

[0068] S22. Emergency response;

[0069] When the oil leakage monitoring module detects oil leakage from the equipment, it first determines whether the equipment itself or the maintenance valve is allowed to be closed, and reports the on-site situation to the task matching module;

[0070] The specific process of matching tasks according to on-site conditions is as follows:

[0071] If the equipment itself and the maintenance valve are both allowed to be closed, the third-level response is initiated, that is, the task execution module closes the equipment and the maintenance valve, and notifies the maintenance personnel to arrive at the site to repair the valve and deal with the oil leak;

[0072] If the equipment itself and the maintenance valve are not allowed to be closed, but the upstream and downstream valves are allowed to be closed, the secondary response is initiated, that is, the task execution module closes the upstream and downstream valves, and notifies the relevant units that the equipment of the corresponding pipe section is temporarily unavailable, and the corresponding position of the pipe section cannot perform refueling operations; wherein, the relevant units include the airport, the aircraft refueling dispatching department and the on-site management department;

[0073] For the second-level response, the on-duty commander and on-site disposal personnel go to the operation site for disposal. Specific disposal measures include checking whether the oil leak is contained, on-site oil leak recovery and treatment, repairing the faulty equipment, and closing the upstream and downstream valves of the corresponding pipe section. After the second-level emergency is initiated, if the on-site disposal personnel rush to the scene and are still unable to control the situation, and the corresponding valve fails and cannot be closed, the commander will determine whether to upgrade to the first-level response. If upgrade is required, the superior person in charge will be reported to the superior person in charge; the superior person in charge refers to the main person in charge of the enterprise. Since the first-level response requires stopping the pump for processing, the entire airport will stop supplying oil. This is a major matter, so the main person in charge of the enterprise needs to issue an order to upgrade the response level.

[0074] The superior person in charge notifies the oil depot to take first-level response measures and notifies relevant units to prepare to stop the oil supply; after receiving the first-level response disposal task, the task execution module takes pump stop measures to stop the oil supply.

[0075] The specific process of restoring the normal state of the equipment and / or valve according to the emergency level is as follows: for a level 3 emergency, when the on-site disposal personnel rush to the site for repair and clean-up, the equipment returns to normal, and the task execution module opens the equipment and valve according to the information fed back by the on-site disposal personnel to restore the use of the equipment and valve;

[0076] For the secondary emergency, when the on-site disposal personnel rush to the site for repair and the equipment returns to normal, the task execution module opens the upstream and downstream valves according to the information fed back by the on-site disposal personnel, and all the equipment in the pipe sections corresponding to the upstream and downstream valves are restored to use;

[0077] For a first-level emergency, when the on-site personnel rush to the site to complete the repairs and the equipment returns to normal, the task execution module restores the oil supply from the oil depot according to the instructions of the superior person in charge and notifies the relevant units that all equipment has returned to normal use.

[0078] S23. Release the emergency measures; restore the equipment and / or valves to normal status according to the emergency level;

[0079] S24. Make a task list;

[0080] According to the apron operation knowledge base, apron operation safety risk base, emergency operation valve operation logic table, emergency level, operation process, operation role configuration, emergency response process and emergency response release process, determine the task list of different roles.

[0081] The oil leakage monitoring module installed on site has a detection function and can monitor the oil leakage status; the linkage emergency disposal module is used to realize the hierarchical linkage action in case of oil leakage; it has an information display function and can understand the information status in real time. At the same time, while receiving real-time information about the equipment and tasks, on-site operators can use the QR code or NFC patch set on the equipment to understand and update the current equipment maintenance status and real-time status by scanning the QR code with a mobile terminal or placing the mobile terminal close to the NFC patch. When an electronic module fails, on-site inspectors can also upload information and trigger emergency tasks through on-site QR codes, NFC patches, etc. The valves include refueling hydrants, valves in valve wells, high-point exhaust valves and / or low-point sinking valves.

[0082] Example 2

[0083] This embodiment is described in conjunction with Example 1. The hierarchical emergency response system for apron fuel supply network equipment described in this embodiment includes an information display module, an equipment maintenance module, and an emergency response module;

[0084] like Figure 1 As shown, the information display module is used to display the real-time status of the equipment; the real-time status of the equipment includes the current open and close status, emergency level status and the current location of the fault point; for information display, the real-time status of the equipment is displayed through the screen, mobile phone and other media to understand the specific location and usage status of the equipment. When the emergency is activated, the equipment changes from green to red, and the related affected equipment will also be highlighted.

[0085] The equipment maintenance module includes an oil leakage monitoring module and a reporting module. The oil leakage monitoring module is used to monitor the real-time status of the equipment and the pipeline network in real time; the equipment maintenance module includes functions such as fault reporting and maintenance result reporting, has its own interface, and has an equipment repair reporting function.

[0086] The emergency response module is used to execute or release the closure of the corresponding equipment or valve according to the task. According to the equipment failure status, the task level is judged and the task is distributed to the designated personnel. At the same time, the task executes the closure of the corresponding equipment or valve or releases the closure of the corresponding equipment or valve. The emergency response module includes functions such as emergency fault reporting and information prompts. It has its own interface and can be implemented on the mobile terminal and the PC. For situations triggered in the command room. Some oil leak discoverers do not have mobile terminals, so they can only report the oil leak status to the duty officer in the command room by phone, and the duty officer uploads relevant information on the PC. In the system role, the duty officer is the person who discovers the oil leak.

[0087] In case of equipment failure, the equipment is equipped with a QR code or NFC patch. When the inspector finds an oil leak, he can scan the QR code with a mobile terminal or bring the mobile terminal close to the NFC patch, and report the current equipment failure through the equipment maintenance module. For situations triggered on site. A QR code or NFC patch associated with the equipment number is arranged on site, which can realize the reporting of emergency information. Scan the QR code with a mobile terminal or bring it close to the NFC patch to trigger the information filling interface of the relevant location.

[0088] The valves include refueling hydrants, valve well valves, high-point exhaust valves and / or low-point sinking valves. There are three main risk levels for emergency situations of apron fuel supply equipment, which are applicable to various valve equipment in the apron fuel supply system, including but not limited to refueling hydrants, valve well valves, high-point exhaust valves, low-point sinking valves, etc.

[0089] If the on-site monitoring equipment is normal:

[0090] The equipment maintenance module finds oil leakage in the fuel hydrant well, triggering the emergency disposal module, and the valve of the fuel hydrant itself begins to close. If the oil leakage is contained after closing, it is a level 3 response. The emergency disposal module notifies the relevant personnel of the on-site disposal task, and the on-site operators come to repair the faulty equipment and deal with the oil leakage site; after the operators finish the processing, they upload the equipment information through the handheld mobile terminal, and the task emergency disposal opens the relevant valves, and the information transmission module changes the equipment status to normal.

[0091] If the oil leakage cannot be stopped after closing the valve itself, the emergency disposal module will close the valve inside the valve well, and transmit the information to the airport, aircraft refueling dispatch department and on-site command department, and the equipment of the relevant pipe section will stop using. After the operator finishes the processing, upload the equipment information through the handheld mobile terminal, the emergency disposal module will open the relevant valve, and the information transmission module will change the equipment status to normal. At the same time, the airport, aircraft refueling dispatch department and on-site command department will return to normal.

[0092] In case of failure of on-site detection equipment:

[0093] After discovering the oil leak, the oil leak detector needs to first perform a simple disposal on the equipment. Therefore, there are only two trigger buttons in the operation interface for the oil leak detector. The first button is "The equipment can be shut down, the oil leak has been controlled", and the second button is "The equipment cannot be shut down, the oil leak cannot be controlled".

[0094] After clicking any button, the interface will upload only the device number (which can be directly identified if triggered on site), on-site photos or videos, and automatically identify the name of the person who discovered the oil leak.

[0095] For the personnel who discovered the oil leak, when they select "Equipment can be shut down, oil leak has been controlled", the system identifies it as a third-level response, and the task is transferred to the equipment maintenance module, and the on-site disposal personnel receive a maintenance work order. At the same time, the system transmits the equipment failure information to the information display module, and personnel from various units can obtain the latest status of the equipment, the affected location and other information. When you select "Equipment cannot be shut down, oil leak cannot be controlled", the system identifies it as a second-level response.

[0096] For on-site disposal personnel, they can obtain the report information of the person who discovered the oil leak and the task list of the corresponding level. At the same time, they can fill in whether the emergency disposal has been completed and whether it is necessary to switch to a maintenance work order. When it is not necessary to switch to a maintenance work order, the equipment returns to normal, the information display module updates the equipment information, and prompts that it has returned to normal, which completes the closing process. When it is necessary to switch to a maintenance work order, when the on-site disposal personnel have repaired the equipment, they report the repair completion information, the information display module updates the equipment information, and prompts that it has returned to normal, which completes the closing process.
