Description

Technical Field

[0001] The present application relates to the technical field of cabin door detection, and in particular to an aircraft cabin door opening and closing detection method, electronic equipment and computer-readable storage medium. Background Art

[0002] The open and closed status of the aircraft door is a key signal for the passenger boarding bridge docking and evacuation process. For example, for an outward-opening door, safety boots can be placed to protect the door only after the door is opened; for another example, the boarding bridge evacuation operation can only be initiated when the door is completely closed.

[0003] For conventional boarding bridges, the opening and closing status of the cabin door mainly depends on the on-site observation and confirmation of the operator. However, with the development of boarding bridge technology, for boarding bridges in remote operation mode or automatic pick-up mode, the operator's operating position has been transferred from the local operating console of the boarding bridge to the remote operation room, and even the operator is not required to operate. In this case, the solution of manually confirming the opening and closing status of the cabin door on site is no longer feasible. After the boarding bridge docks with the aircraft, the cabin door opens, and the safety boots can be put on at this time. After that, the operator will move to other boarding bridges to continue operating. When the aircraft completes boarding and disembarking and the cabin door is closed, the system needs to automatically detect that the cabin door is in a closed state and promptly notify the operator to evacuate the boarding bridge to ensure the smooth progress of the automated process.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] See also Figure 1 As shown, this embodiment provides a method for detecting the opening and closing of an aircraft cabin door, comprising:

[0048] Step S102, obtaining real-time point cloud data of the line beam scanning aircraft;

[0049] Step S104, performing real-time feature recognition and real-time parameter extraction on the real-time point cloud data;

[0050] Step S106, determining the open or closed state of the aircraft door according to the set judgment rule.

[0051] The aircraft cabin door opening and closing detection method provided in this embodiment obtains real-time point cloud data of a line beam scanning aircraft, performs real-time feature recognition and real-time parameter extraction on the real-time point cloud data, and then determines the opening and closing status of the aircraft cabin door according to set judgment rules. This method can simply and quickly realize reliable detection of the opening and closing status of the cabin door, with low overall data processing and computing power.

[0052] In step S102, real-time point cloud data of the line beam scanning aircraft is obtained, including:

[0053] Establish a coordinate system; use detection elements to scan the aircraft, obtain data information at each scanning point of the aircraft in the scanning area, and the data information at all scanning points forms real-time point cloud data.

[0054] Exemplarily, a coordinate system may be established with the light beam emission point of the detection element as the origin, the light beam emission direction of the detection element as the X-axis, and the left-right direction of the detection element as the Y-axis.

[0055] In this embodiment, the scanning area is a line segment located in the XY plane and parallel to the Y axis.

[0056] The detection element may be a sensor 111. The sensor may be disposed at the receiving port 11 of the boarding bridge 1, for example, Figure 1As shown, the sensor 111 is arranged above the passenger entrance 11 of the boarding bridge 1. Due to the high installation height, the sensor 111 can completely avoid the influence of the luggage on the ground. This embodiment adopts the laser radar detection method to realize the detection of the opening and closing of the aircraft cabin door 21. Of course, the millimeter wave radar detection method and any other suitable detection method can also be used.

[0057] The opening and closing states of the aircraft cabin door include but are not limited to: closed state, in the process of opening, open state, and in the process of closing.

[0058] When the aircraft door is opened or closed, the real-time point cloud data of the aircraft door is obtained at a set frequency, and the open and closed status of the aircraft door is determined according to the set judgment rules. According to the status of the aircraft door, status information is provided to other work links or staff.

[0059] In some embodiments, the set judgment rules include: when the real-time feature is a substantially continuous portion, it is judged that the aircraft door is in a closed state.

[0060] Specifically, when the sensor scans aircraft 2, it will obtain aircraft 2 at each scanning point D k The data information on all scanning points forms point cloud data D. Figure 5 As shown, after the boarding bridge 1 is properly connected to the aircraft 2, the sensor can obtain the point cloud data D of the aircraft 2 within the scanning range through radar scanning. By filtering the radar point cloud, the discrete points at the corners are filtered out to reduce their interference with the subsequent algorithm. When the aircraft door 21 is closed, the aircraft 2 is a continuous curve in the scanning area S, and the point cloud data D of the fuselage scanned by the detection device 111 is also continuous, and there will be no data mutation. Therefore, when the real-time feature is a basically continuous curve, it is judged that the aircraft door is in a closed state.

[0061] In this embodiment, Figures 5 to 10 In all the point cloud data schematic diagrams shown, the horizontal direction is the scanning points of the aircraft on the corresponding scanning area, and the vertical direction is the distance or time of the scanning results of each scanning point.

[0062] In some embodiments, when the previous state is a closed state, it is pre-determined that the next state is a start-up process state or an open state.

[0063] For example, when the aircraft has stopped, the boarding bridge 1 has not yet been docked on the fuselage of the aircraft 2, or has just been docked on the fuselage of the aircraft, and the aircraft door is in a closed state, that is, the previous state is a closed state. At this time, it is pre-judged that the next state is an opening process state or an open state to ensure that passengers can get on and off the plane.

[0064] The aircraft cabin door can be an outward-opening door or an inward-opening door. In this embodiment, the model of the docking aircraft can be obtained by communicating with the Visual Docking Guidance Systems (VDGS) or other airport systems to determine whether it is an outward-opening door or an inward-opening door. The bridge operator can also choose to input an outward-opening door or an inward-opening door.

[0065] The following will detail the judgment rules set according to real-time characteristics and real-time parameters when the aircraft cabin door is an outward-opening cabin door, and the implementation scheme for determining the open and closed state of the outward-opening cabin door based on the judgment rules.

[0066] In some embodiments, the set judgment rules include:

[0067] When the current state is the closed state, and when the real-time feature includes three discontinuous parts: the scanned part A1 of the aircraft outer surface, the scanned part B1 of the cabin door and the scanned part C1 of the aircraft outer surface, and at least one of the following conditions is met: the length L1 of the scanned part B1 of the cabin door is greater than or equal to the opening width threshold of the outward-opening cabin door, the disconnection distance L2 between the scanned part A1 of the aircraft outer surface and the scanned part B1 of the cabin door is greater than or equal to the left opening gap threshold, and the disconnection distance L3 between the scanned part B1 of the cabin door and the scanned part C1 of the aircraft outer surface is greater than or equal to the right opening door gap threshold, it is judged that the aircraft cabin door is in the opening process.

[0068] Specifically, see Figure 6 As shown, the point cloud data D may not be on a line segment at the junction of the scanned portion A1 of the aircraft outer surface and the scanned portion B1 of the cabin door, and at the junction of the scanned portion B1 of the cabin door and the scanned portion C1 of the aircraft outer surface. Here, the scanned portion A1 of the aircraft outer surface, the scanned portion B1 of the cabin door, and the scanned portion C1 of the aircraft outer surface can all be detected and segmented using the regional growing algorithm. By analyzing the point cloud data D and extracting real-time parameters, the open and closed state of the aircraft cabin door 21 can be determined according to the corresponding judgment rules.

[0069] When the real-time parameters meet at least one of the following three conditions, it is determined that the outward-opening aircraft door is in the opening process.

[0070] Exemplarily, the first condition is that the length L1 of the scanned portion B1 of the door is greater than or equal to the opening width threshold of the outward-opening door, where L1 is the distance between the two ends of the scanned portion B1 of the door, and the opening width threshold of the outward-opening door is a set threshold value obtained according to big data for determining the start of the opening process state.

[0071] Condition 2 is that the disconnection distance L2 between the scanned portion A1 of the aircraft outer surface and the scanned portion B1 of the cabin door is greater than or equal to the left opening gap threshold, where L2 is the horizontal distance between the two end points of the scanned portion A1 of the aircraft outer surface and the scanned portion B1 of the cabin door that are close to each other, and the left opening gap threshold is a set threshold value obtained according to big data for judging that the outward-opening cabin door begins to enter the opening process state.

[0072] Condition three is when the disconnection distance L3 between the scanned portion B1 of the cabin door and the scanned portion C1 of the aircraft outer surface is greater than or equal to the right opening door gap threshold. Wherein, L3 is the horizontal distance between the two end points of the scanned portion B1 of the cabin door and the scanned portion C1 of the aircraft outer surface, and the right opening door gap threshold is a set threshold value obtained according to big data for judging that the outward-opening cabin door begins to enter the opening process state.

[0073] It should be noted that the point cloud data corresponding to the area of ​​the door opening 22 after opening is automatically filtered out according to the distance or time greater than the set value.

[0074] In some embodiments, the set judgment rules include: when the current state is an open state, and when the real-time feature includes three discontinuous parts: the scanned part A1 of the aircraft's outer surface, the scanned part B1 of the cabin door, and the scanned part C1 of the aircraft's outer surface, and at least one of the following conditions is met: the length L4 of the scanned part B1 of the cabin door is less than or equal to the closing width threshold of the outward-opening cabin door, the disconnection distance L5 between the scanned part A1 of the aircraft's outer surface and the scanned part B1 of the cabin door is less than or equal to the left closing gap threshold, and the disconnection distance L6 between the scanned part B1 of the cabin door and the scanned part C1 of the aircraft's outer surface is less than or equal to the right closing door gap threshold, it is judged that the aircraft cabin door is in the closing process.

[0075] Specifically, when the aircraft cabin door 21 begins to close, the real-time features of the aircraft within the scanning range scanned by the sensor 111 include three discontinuous parts: the scanned part A1 of the aircraft outer surface, the scanned part B1 of the cabin door, and the scanned part C1 of the aircraft outer surface. By analyzing the point cloud data D and extracting the real-time parameters, the open and closed state of the aircraft cabin door 21 can be judged according to the corresponding judgment rules.

[0076] When the real-time parameters meet at least one of the following three conditions, it is determined that the aircraft door is in the closing process.

[0077] Exemplarily, condition (1) is that the length L4 of the scanned portion B1 of the door is less than or equal to the closed width threshold of the outward-opening door, where L4 is the distance between the two ends of the scanned portion B1 of the door, and the closed width threshold of the outward-opening door is a threshold of big data statistics, for example, the threshold may be the minimum width value of the outward-opening door.

[0078] Condition (2) is that the disconnection distance L5 between the scanned portion A1 of the aircraft outer surface and the scanned portion B1 of the cabin door is less than or equal to the left closing gap threshold. Wherein, L5 is the horizontal distance between the two end points of the scanned portion A1 of the aircraft outer surface and the scanned portion B1 of the cabin door that are close to each other, and the left closing gap threshold is a set threshold value obtained according to big data for judging whether the outward-opening cabin door begins to enter the closing process state.

[0079] Condition (3) is that the disconnection distance L6 between the scanned portion B1 of the cabin door and the scanned portion C1 of the aircraft outer surface is less than or equal to the right closing door gap threshold. Wherein, L6 is the horizontal distance between the two end points of the scanned portion B1 of the cabin door and the scanned portion C1 of the aircraft outer surface, and the right closing door gap threshold is a set threshold value obtained according to big data for judging whether the outward-opening cabin door has begun to enter the closing process state.

[0080] It should be noted that the left closing gap threshold and the left opening gap threshold can be the same or different; the right closing door gap threshold and the right opening door gap threshold can be the same or different.

[0081] In some embodiments, the judgment rule also includes: starting from the first judgment that the outward-opening aircraft cabin door is in the opening process, after the duration reaches the cabin door fully open time threshold, the outward-opening aircraft cabin door is judged to be in the open state. The cabin door fully open time threshold here takes into account the longest time required for the cabin door of various aircraft models to open obtained from big data statistics, and this design does not rely on any sensor or model information.

[0082] After the cabin door is opened, for the outward-opening cabin door, the real-time parameters always meet the above condition one, and at least one of the conditions two and three at the same time, so even if there are passengers passing through, it can be reliably judged that the current cabin door is in the open state.

[0083] In some embodiments, the judgment rule also includes: starting from the first judgment that the outward-opening aircraft cabin door is in the closing process, after the duration reaches the cabin door fully closed time threshold, the outward-opening aircraft cabin door is judged to be in the closed state. The cabin door fully closed time threshold here takes into account the longest time required for the cabin door of various aircraft models to close obtained from big data statistics, and this design does not rely on any sensor or model information.

[0084] In other embodiments, the following judgment rules may also be used to judge whether the outward-opening aircraft door is in the open state.

[0085] Specifically, the judgment rules set include: when the current sequence state is closed, such as Figure 7As shown, the real-time features of the aircraft within the scanning range scanned by the sensor 111 include three discontinuous parts: the scanned part A1 of the aircraft outer surface, the scanned part B1 of the cabin door, and the scanned part C1 of the aircraft outer surface. By analyzing the point cloud data D and extracting the real-time parameters, the open or closed state of the aircraft cabin door 21 can be judged according to the corresponding judgment rules.

[0086] When the real-time parameters meet at least one of the following eight conditions, it is determined that the outward-opening aircraft door is in the open state.

[0087] Condition ①: The length L7 of the scanned portion A1 of the aircraft outer surface is within the first threshold range;

[0088] Condition ②: The ratio R1 of L7 to the overall length is within the second threshold range;

[0089] Condition ③: the gap width W3 between the scanned portion A1 of the aircraft outer surface and the scanned portion C1 of the aircraft outer surface is within the third threshold range;

[0090] Condition ④: The ratio R2 of W3 to the overall length is within the fourth threshold range;

[0091] Condition ⑤: The sum L8 of the lengths of the scanned portion A1 of the aircraft outer surface and the scanned portion B1 of the cabin door is within the fifth threshold range;

[0092] Condition ⑥: The ratio R3 of L8 to the overall length is within the sixth threshold range;

[0093] Condition ⑦: the gap width W4 between the scanned portion B1 of the cabin door and the scanned portion C1 of the aircraft outer surface is within the seventh threshold range;

[0094] Condition ⑧: The ratio R4 of W4 to the overall length is within the eighth threshold range.

[0095] The following will detail the judgment rules set according to real-time characteristics and real-time parameters when the aircraft cabin door is an inward-opening cabin door, and the implementation scheme for determining the open and closed state of the inward-opening cabin door based on the judgment rules.

[0096] In one embodiment, the judgment rules set include: when the current sequence state is the closed state, such as Figure 8As shown, when the real-time feature includes two discontinuous parts: the scanned part A2 of the outer surface of the aircraft and the scanned part C2 of the outer surface of the aircraft, and at least one of the following conditions is met: the gap width W1 between the scanned part A2 of the outer surface of the aircraft and the scanned part C2 of the outer surface of the aircraft is greater than or equal to the opening width threshold of the inner door, and the ratio of the sum of the lengths of the scanned part A2 of the outer surface of the aircraft and the scanned part C2 of the outer surface of the aircraft to the overall length is less than or equal to the opening ratio threshold of the inner door, it is judged that the aircraft door is in the opening process; wherein the overall length is the sum of the length of the scanned part A2 of the outer surface of the aircraft, the length of the scanned part C2 of the outer surface of the aircraft and W1.

[0097] Here, the scanned portion A2 of the aircraft outer surface and the scanned portion C2 of the aircraft outer surface can both be detected and segmented using the region growing algorithm. The point cloud data D scanned by the sensor 111 is disconnected for a long distance between A2 and C2. By analyzing the point cloud data D and extracting real-time parameters, the open and closed state of the aircraft cabin door 21 can be determined according to the corresponding judgment rules.

[0098] When the real-time parameters satisfy at least one of the following two conditions, it is determined that the inward-opening aircraft door is in the opening process.

[0099] Exemplarily, condition (a) is that the gap width W1 between the scanned portion A2 of the aircraft outer surface and the scanned portion C2 of the aircraft outer surface is greater than or equal to the opening width threshold of the inner door. Wherein, W1 is the distance between the two end points of the scanned portion A2 of the aircraft outer surface and the scanned portion C2 of the aircraft outer surface that are close to each other, and the opening width threshold of the inner door is a set threshold value obtained according to big data for determining the start of the opening process state.

[0100] Condition (b) is that the ratio of the sum of the lengths of the scanned portion A2 of the outer surface of the aircraft and the scanned portion C2 of the outer surface of the aircraft to the overall length is less than or equal to the threshold value of the opening ratio of the inner door. The overall length is the sum of the length of the scanned portion A2 of the outer surface of the aircraft, the length of the scanned portion C2 of the outer surface of the aircraft and W1, and the threshold value of the opening ratio of the inner door is a set threshold value obtained according to big data for determining the start of the opening process state.

[0101] It should be noted that the point cloud data corresponding to the area of ​​the door opening 22 after opening is automatically filtered out according to the distance or time greater than the set value.

[0102] In some embodiments, the set judgment rules also include: when the current state is an open state, and when the real-time feature includes two discontinuous parts: the scanned part A2 of the outer surface of the aircraft and the scanned part C2 of the outer surface of the aircraft, and at least one of the following conditions is met: the gap width W2 between the scanned part A2 of the outer surface of the aircraft and the scanned part C2 of the outer surface of the aircraft is less than or equal to the closing threshold of the inner opening door, and the ratio of the sum of the lengths of the scanned part A2 of the outer surface of the aircraft and the scanned part C2 of the outer surface of the aircraft to the overall length is less than or equal to the closing ratio threshold of the inner opening door, it is judged that the aircraft door is in the closing process; wherein, the overall length is the sum of the length of the scanned part A2 of the outer surface of the aircraft, the length of the scanned part C2 of the outer surface of the aircraft and W2.

[0103] Specifically, when the aircraft door 21 begins to close, the real-time features of the aircraft within the scanning range scanned by the sensor 111 include two discontinuous parts: the scanned part A2 of the aircraft outer surface and the scanned part C2 of the aircraft outer surface. By analyzing the point cloud data D and extracting the real-time parameters, the open and closed state of the aircraft door 21 can be judged according to the corresponding judgment rules.

[0104] When the real-time parameters meet at least one of the following two conditions, it is determined that the aircraft door is in the closing process.

[0105] Exemplarily, condition I is that the gap width W2 between the scanned portion A2 of the aircraft outer surface and the scanned portion C2 of the aircraft outer surface is less than or equal to the closing threshold of the inward-opening door. Wherein, W2 is the distance between the two end points of the scanned portion A2 of the aircraft outer surface and the scanned portion C2 of the aircraft outer surface that are close to each other, and the closing threshold of the inward-opening door is a set threshold value obtained according to big data for judging that the inward-opening door begins to enter the closing process state.

[0106] Condition II is that the ratio of the sum of the lengths of the scanned portion A2 of the aircraft's outer surface and the scanned portion C2 of the aircraft's outer surface to the overall length is less than or equal to the closing ratio threshold of the inward-opening door. The overall length is the sum of the length of the scanned portion A2 of the aircraft's outer surface, the length of the scanned portion C2 of the aircraft's outer surface, and W2. The closing ratio threshold of the inward-opening door is a set threshold value obtained according to big data for judging that the inward-opening door has begun to enter the closing process state.

[0107] In some embodiments, the set judgment rules also include:

[0108] The inward-opening aircraft door is judged to be in the open state from the time when it is first judged that the inward-opening aircraft door is in the opening process. After the duration reaches the door fully open time threshold, the inward-opening aircraft door is judged to be in the open state.

[0109] like Fig. 9As shown in the figure, for an inward-opening door, when the door is opened, if a pedestrian or luggage blocks part of the scanning curve at the fuselage position, there are at least two situations: one is that since the curve is not connected to the fuselage, the pedestrian at this location can be ignored by the algorithm. Another is that even if the pedestrian is connected to the door, there will be some fluctuations because the outline of the pedestrian or luggage is different from the relatively smooth curve of the fuselage. The length of this part of the pedestrian or luggage can be filtered by the orthogonal fitting threshold, which can effectively avoid false alarms of the door closing.

[0110] In some embodiments, the judgment rule also includes: starting from the first judgment that the inward-opening aircraft cabin door is in the closing process, after the duration reaches the cabin door fully closed time threshold, the inward-opening aircraft cabin door is judged to be in the closed state. The cabin door fully closed time threshold here takes into account the longest time required for the cabin door of various aircraft models to close obtained from big data statistics, and this design does not rely on any sensor or model information.

[0111] In other embodiments, the following judgment rules may also be used to judge whether the inward-opening aircraft door is in the open state.

[0112] Specifically, the judgment rules set include: when the current sequence state is closed, see Fig.10 As shown, the real-time features of the aircraft within the scanning range scanned by the sensor 111 include two discontinuous parts: the scanned part A2 of the aircraft outer surface and the scanned part C2 of the aircraft outer surface. By analyzing the point cloud data D and extracting the real-time parameters, the open or closed state of the aircraft cabin door 21 can be judged according to the corresponding judgment rules.

[0113] When the real-time parameters satisfy at least one of the following two conditions, it is determined that the inward-opening aircraft door is in the open state.

[0114] Condition (I) The gap width W5 between the scanned portion A2 of the aircraft outer surface and the scanned portion C2 of the aircraft outer surface is greater than or equal to a first set threshold, wherein W5 is the distance between two end points of the scanned portion A2 of the aircraft outer surface and the scanned portion C2 of the aircraft outer surface that are close to each other.

[0115] Condition (II) The ratio of the sum of the lengths of the scanned portion A2 of the outer surface of the aircraft and the scanned portion C2 of the outer surface of the aircraft to the overall length is less than or equal to a second set threshold value. The overall length is the sum of the length of the scanned portion A2 of the outer surface of the aircraft, the length of the scanned portion C2 of the outer surface of the aircraft and W5.

[0116] In some embodiments, the aircraft cabin door opening and closing detection method further includes: during the duration of the aircraft cabin door being in the process of opening, if one or more detection results determine that the aircraft cabin door is in a closed state, an alarm is issued; during the duration of the aircraft cabin door being in the process of closing, if one or more detection results determine that the aircraft cabin door is in an open state, an alarm is issued. For example, an alarm device such as an audible and visual alarm may be used to issue an alarm to prompt the staff to take corresponding emergency measures.

[0117] In some embodiments, when the aircraft door is already in an open state, a detection interruption time is set so that the door state is not detected during the passenger's passage. When the passenger has passed, the aircraft door is re-detected to determine whether it is in a closed state. The detection interruption time can be set according to actual conditions.

[0118] In other embodiments, during the passage of passengers, the open and closed state of the aircraft door may also be continuously or intermittently detected, wherein the interval of the intermittent detection may be set according to actual conditions.

[0119] The aircraft cabin door opening and closing detection method provided in this embodiment can simply and quickly realize cabin door status detection and judgment, with a small amount of overall data processing and calculation, and can reliably realize cabin door opening and closing status detection.

[0120] It should be noted that, during the detection of the opening and closing status of the aircraft cabin door, each set threshold value can be adjusted according to actual conditions to ensure the efficiency of the detection process and the accuracy of the detection results.

[0121] Based on the same inventive concept, this embodiment also provides an aircraft cabin door opening and closing detection device, such as the following embodiment.

After detecting that the cabin door is open, the cabin door opening signal is given to the boarding bridge PLC control system. After the aircraft completes the passenger disembarkation and boarding process, the cabin door begins to close, and the real-time point cloud data of the cabin door is used to determine whether the cabin door is closed. After detecting that the cabin door is closed, the cabin door closing signal is given to the boarding bridge PLC control system, and the PLC control system starts the boarding bridge evacuation process.
