Description

TECHNICAL FIELD

[0001] The present application relates to the elevator door operation and maintenance technical field, especially to an elevator door operation and maintenance method, system, intelligent terminal and storage medium. BACKGROUND

[0002] At present, as an indispensable vertical traffic tool in high-rise buildings, the safety and reliability of the elevator are directly related to the efficiency and safety of personnel travel. The elevator door includes the landing door of the car and the hall door set at each floor of the building. The opening and closing of the elevator door depend on the door machine and the transmission components (such as door knife, belt, door rail, etc.) driven by the door machine, and the door machine is controlled by the door machine controller to realize automatic control. During the operation of the elevator and the passenger boarding process, the synchronous opening and closing of the landing door and the hall door directly affect the passage and safety of the passengers.

[0003] In actual application, the running frequency of the elevator door is high, and the frequent opening and closing actions cause the door machine and its associated components to have problems such as wear, increased resistance, or misalignment. If these potential abnormalities cannot be found in time, they may further develop into faults such as door not closing tightly, slow opening and closing, and false triggering of emergency stop signals, which may even affect the normal operation of the elevator and the safety of passengers. In the prior art, the detection and maintenance of the elevator door mainly rely on regular maintenance and after-service repair. Among them, regular maintenance is to manually check, clean, and adjust the elevator door within a fixed period. After-service repair refers to repairing the elevator door when it has obvious faults, such as fault codes in the door machine controller.

[0004] For the related technology in the above, the potential abnormalities existing in the running process of the elevator door cannot be identified, so that the elevator door has safety hazards. SUMMARY

[0005] In order to identify the potential abnormalities existing in the running process of the elevator door and reduce the safety hazards of the elevator door, the present application provides an elevator door operation and maintenance method, system, intelligent terminal and storage medium.

[0006] In the first aspect, the present application provides an elevator door operation and maintenance method, which adopts the following technical scheme: An elevator door operation and maintenance method, comprising: in response to a closing instruction of the landing door, controlling the landing door to execute a closing step; after executing the closing step once, acquiring a driving frequency record of the door machine; determining whether there is a driving frequency in the driving frequency record that does not conform to a preset driving frequency interval; if so, marking the driving frequency in the driving frequency record that does not conform to the preset driving frequency interval as a target driving frequency; obtain a target time period corresponding to the target driving frequency, wherein the target time period is at least one of a starting period, an acceleration period, a constant speed period, a deceleration period, and a maintaining period included in the total time period; In the target time period, it is determined whether an emergency stop signal is received; If not, the target time period is associated with the door body operation data to determine an abnormal occurrence section; Generate abnormal information corresponding to the abnormal occurrence section, and upload the abnormal information to the maintenance platform.

[0007] By adopting the above technical solution, after executing the step of closing the landing door, the driving frequency record of the door machine is obtained, the target driving frequency is obtained based on the driving frequency record, and the target time period is obtained through the target driving frequency. In the case where no emergency stop signal is received, the existence of the target driving frequency indicates that there is a potential abnormal problem in the closing process of the elevator door, so the abnormal driving is determined by combining the target time period and the door body operation data, and the corresponding abnormal information is generated and uploaded to the operation and maintenance platform. Maintenance personnel can timely discover and make corresponding maintenance work, so as to realize the identification of potential abnormalities in the running process of the elevator door and reduce the safety hazards of the elevator door.

[0008] Optionally, the driving frequency records of all floors are obtained; Map the driving frequency records of all floors to the same coordinate system to obtain a driving frequency distribution map; Based on the driving frequency distribution map, it is determined whether the synchronization rate of the time period corresponding to the target driving frequency in the driving frequency record of each floor is greater than a preset synchronization rate; If yes, the time period corresponding to the target driving frequency in the driving frequency record of each floor is marked as an abnormal time period; Based on the abnormal time period and the door body operation data, corresponding execution component information is obtained; Add the execution component information to the landing door abnormal information; If not, output the elevator door abnormal information according to the preset detection method.

[0009] By adopting the above technical solution, by obtaining the driving frequency records of all floors, and based on the driving frequency distribution map, the synchronization rate of the time period corresponding to the target driving frequency is obtained. In the case where the synchronization rate is greater than the preset synchronization rate, it is indicated that the probability of each floor having an abnormal problem in the time period is relatively high, so it can be inferred that the abnormal problem exists in the landing door and its associated components. Through the abnormal time period and the door body operation data, the execution component information of the current execution door body during movement can be obtained, and the execution component information is added to the landing door abnormal information, so that maintenance personnel can carry out targeted maintenance and maintenance, improve the fault handling efficiency and the safety of elevator operation.

[0010] Optionally, it is judged whether the proportion of the abnormal time period in the total time period is greater than a preset time proportion; If yes, the layer door operation section corresponding to the abnormal time period is marked as a continuous abnormal area; According to the continuous abnormal area, high-warning maintenance information including a prompt for detecting layer door moving mechanism abnormalities is generated; If no, the layer door operation section corresponding to the abnormal time period is marked as a local abnormal area; According to the local abnormal area, low-warning maintenance information including a prompt for executing part information and a local obstacle is generated; The first maintenance information or the second maintenance information is added to the layer door abnormal information.

[0011] By adopting the above technical solution, the proportion of the abnormal time period in the total time period is obtained. In the case where the obtained proportion is greater than the preset time proportion, it is indicated that there is a continuous abnormality, and therefore high-warning maintenance information needs to be generated for maintenance personnel to timely handle and repair. In the case where the obtained proportion is not greater than the preset time proportion, it is indicated that the existing abnormality is local and periodic, and therefore low-warning maintenance information with relatively low warning can be generated.

[0012] Optionally, a door opening driving frequency record when the door opening step is executed is obtained; According to the door opening driving frequency record, a target door opening driving frequency corresponding to the door opening driving frequency record is obtained; It is judged whether the time period corresponding to the target door opening driving frequency is the same as the time period corresponding to the target frequency; If yes, local obstacle information is added to the layer door abnormal information; If no, a current value of the door machine in the target time period is obtained to obtain a target current value; It is judged whether there is an abnormal increase section in the target current value; If yes, local obstacle information is added to the layer door abnormal information; If no, door machine abnormal information is added to the layer door abnormal information.

[0013] By adopting the technical scheme, when the door opening driving frequency is consistent with the target driving frequency time period, it indicates that the local obstacle causes an abnormality in the running process of the landing door, and therefore the local obstacle information can be added in the landing door abnormality information. When the two time periods are inconsistent, the presence of an abnormal increase section can be determined in combination with the door machine current value, which indicates whether the door machine is blocked in the running process. In the case of the presence of the abnormal increase section, it indicates that there is a local obstacle, and therefore the local obstacle information is added in the landing door abnormality information. In the case of the absence of the abnormal increase section, it indicates that an abnormality occurs in the running process of the door machine, and therefore the door machine abnormality information is added in the landing door abnormality information. The accuracy and pertinence of abnormality identification are improved, the maintenance personnel can timely locate the specific fault component, and the elevator door maintenance efficiency and safety guarantee level are improved.

[0014] Optionally, the step of outputting the elevator door abnormality information according to the preset detection method comprises: marking a floor corresponding to the target driving frequency to obtain a target floor; pulling a driving frequency record of the target floor in a preset time period from a historical record to obtain a historical driving frequency record set; acquiring a number of occurrences of the target driving frequency based on the driving frequency record set; determining whether the number of occurrences is less than a preset number threshold; if yes, outputting hall door abnormality information containing the target floor information; if no, outputting abnormality information according to a preset abnormality analysis method.

[0015] By adopting the technical scheme, the number of occurrences of the target driving frequency can be acquired according to the historical driving frequency record set of the target floor. If the number of occurrences is less than the preset number threshold, it indicates that the probability of the presence of an abnormality in the landing door and its associated components is small, and the probability of the presence of an abnormality in the hall door and its associated components is large, and therefore the hall door abnormality information containing the target floor information is outputted. If the number of occurrences is not less than the preset number threshold, the abnormality is further analyzed by the preset abnormality analysis method. The source of the running abnormality problem can be determined.

[0016] Optionally, the step of outputting the abnormality information according to the preset abnormality analysis method comprises: acquiring a historical driving frequency record of a neighboring floor of the target floor to obtain a neighboring historical driving frequency record set; acquiring a concentrated time period of the occurrence of the target driving frequency based on the historical driving frequency record set; determining whether a deviation value of the time of the occurrence of the target driving frequency from the concentrated time in the neighboring historical driving frequency record set is greater than a preset deviation range; if yes, generating landing door abnormality information of the landing door and its associated components; If no, the hall door abnormal information containing the target floor is generated.

[0017] By adopting the technical scheme, the historical driving frequency record of the adjacent floor is acquired, if the layer door and the associated components are abnormal, the time when the running abnormal problem occurs in the process of closing the layer door in the adjacent floor is approximately the same, that is, the deviation value is not greater than the preset deviation range, and therefore the layer door abnormal information of the layer door and the associated components is generated, otherwise the hall door abnormal information containing the target floor is generated, so as to realize the positioning of the running abnormal problem.

[0018] Optionally, the number of time periods contained in the target time period is acquired, and the number of time periods is obtained. The target time with the number of time periods greater than the preset number of time periods is marked to obtain a high warning target time period. It is judged whether the floor corresponding to the high warning target time period is the first floor. If yes, the elevator call function of all floors corresponding to the elevator corresponding to the high warning target time period is suspended. If no, the elevator call function of the floor where the high warning target time period is located is suspended.

[0019] By adopting the technical scheme, it can be determined whether it is a high warning target time period according to the number of time periods contained in the target time period, and further, if the floor corresponding to the high warning target time period is the first floor, the elevator call function of all floors is suspended, and if the high warning target time period is not the first floor, only the elevator call function of the floor corresponding to the high warning target time period is suspended, which helps to ensure the carrying capacity of the elevator under the premise of ensuring the safety of passengers.

[0020] In a second aspect, the application provides an elevator door operation and maintenance system, which adopts the following technical scheme: An elevator door operation and maintenance system comprises: An acquisition module is configured to acquire driving frequency records, time periods, and emergency stop signals. A memory is configured to store the program of the elevator door operation and maintenance method. A processor, the program in the memory can be loaded and executed by the processor and implement the elevator door operation and maintenance method.

[0021] By adopting the above technical solution, after executing the floor door closing step once, the driving frequency record of the door machine is obtained, and the target driving frequency is obtained based on the driving frequency record. The target time period is obtained through the target driving frequency. In the case that no emergency stop signal is received, the existence of the target driving frequency indicates that there is a potential operation abnormality problem in the closing process of the elevator door. Therefore, the abnormal drive is determined in combination with the target time period and the door body operation data, and the corresponding abnormality information is generated and uploaded to the operation and maintenance platform for the operation and maintenance personnel to discover and perform corresponding maintenance work in time, so as to realize the identification of potential abnormalities in the operation of the elevator door and reduce the safety hazards of the elevator door.

[0022] In a third aspect, the present application provides a smart terminal that adopts the following technical solution: An intelligent terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute any one of the methods described above.

[0023] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which facilitates the identification of potential abnormalities in elevator doors during operation to reduce safety hazards of elevator doors, and adopts the following technical solutions: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned elevator door operation and maintenance methods.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. After executing the landing door closing step once, the target driving frequency is obtained based on the driving frequency record obtained by obtaining the door machine's driving frequency record. The target time period is obtained based on the target driving frequency. In the absence of an emergency stop signal, the existence of the target driving frequency indicates that there is a potential abnormal operation problem during the closing process of the elevator door. Therefore, the abnormal drive is determined by combining the target time period and the door body operation data. The corresponding abnormal information is generated and uploaded to the operation and maintenance platform for operation and maintenance personnel to discover and perform corresponding maintenance work in a timely manner, so as to realize the identification of potential abnormalities in the operation of the elevator door and reduce the safety hazards of the elevator door. 2. When the door opening drive frequency is consistent with the target drive frequency time period, it indicates that the floor door has an abnormality due to a local obstacle during operation, so the local obstacle information can be added to the floor door abnormality information. When the two time periods are inconsistent, combined with the door machine current value, it can be determined whether the door machine is blocked during operation, that is, the appearance of an abnormal increase segment. In the case of an abnormal increase segment, it indicates that there is a local obstacle, so the local obstacle information is added to the floor door abnormality information; in the case of no abnormal increase segment, it indicates that an abnormality has occurred during the operation of the door machine, so the door machine abnormality information is added to the floor door abnormality information. This helps to improve the accuracy and pertinence of abnormality identification, helps maintenance personnel to locate specific faulty components in a timely manner, and improves the efficiency of elevator door maintenance and the level of safety assurance. 3. By obtaining the historical drive frequency records of adjacent floors, if there is an abnormality in the landing door and its associated components, the time when the operation abnormality occurs during the closing process of the landing doors on the adjacent floors is roughly the same, that is, the deviation value is not greater than the preset deviation range. Therefore, the landing door abnormality information of the abnormal landing door and its associated components is generated. Otherwise, the landing door abnormality information including the target floor is generated to locate the operation abnormality. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1 -AttachedFigure 7 and embodiments. It should be understood that the specific embodiments described herein are meant to be illustrative only and not limiting as to the scope of the application.

[0033] The embodiments of the present application disclose an elevator door operation and maintenance method. Referring to Figure 1 , the elevator door operation and maintenance method comprises: Step S101: in response to a closing instruction of a landing door, controlling the landing door to perform a closing step.

[0034] The closing instruction refers to a control signal sent by a door machine controller after a bridge box stops at a floor and completes door opening and stopping, which is used to trigger the door machine and control the landing door to perform a closing action.

[0035] After receiving the closing instruction, the door machine controls the landing door to close. In the process of controlling the landing door to close, the door machine will go through a start-up, acceleration, constant speed, deceleration and holding stage in sequence according to a preset driving frequency curve, to ensure that the speed and torque of the landing door closing meet the safety specifications, and in this closing process, the landing door position, the driving frequency of the door machine and the running current will be collected in real time for subsequent detection.

[0036] Step S102: obtaining a driving frequency record of the door machine after performing a closing step.

[0037] The closing step refers to the landing door changing from an open state to a closed state.

[0038] The driving frequency record refers to a sample data set of the driving frequency of the driving motor changing with time in the process of the door machine performing the closing step, which is used to reflect the running state and load characteristics of the landing door closing. The driving frequency refers to the actual working frequency of the door machine in the running process. The driving frequency record is divided into a start-up section, an acceleration section, a constant speed section, a deceleration section and a holding section.

[0039] Step S103: judging whether there is a driving frequency in the driving frequency record that does not conform to a preset driving frequency interval.

[0040] The preset driving frequency interval is a preset interval, which covers the normal running frequency of the driving frequency of the door machine in the start-up section, the acceleration section, the constant speed section, the deceleration section and the holding section.

[0041] The purpose of performing the judgment step is to detect whether there is an abnormal phenomenon in the closing process of the landing door.

[0042] Step S104: if yes, marking the driving frequency in the driving frequency record that does not conform to the preset driving frequency interval as a target driving frequency.

[0043] In another aspect, if the driving frequency in the driving frequency record does not conform to the preset driving frequency interval, no further processing is performed.

[0044] In the presence of the target driving frequency, it can be defined that there is a running abnormality problem in the current layer door closing step.

[0045] For example, if the acceleration segment in the driving frequency record does not conform to the corresponding preset driving frequency interval, the driving frequency of this segment is marked as the target driving frequency. If the acceleration segment and the constant speed segment in the driving frequency record do not conform to the corresponding preset driving frequency interval, the driving frequency of the acceleration segment and the constant speed segment is marked as the target driving frequency. Step S105: Obtain the time period corresponding to the target driving frequency to obtain the target time period, wherein the target time period is at least one of the start period, the acceleration period, the constant speed period, the deceleration period and the holding period included in the total time period.

[0046] The total time period refers to the complete running time of the layer door executing a closing step. The total time period includes the start period, the acceleration period, the constant speed period, the deceleration period and the holding period, and the division of the total time period is synchronized with the driving frequency record.

[0047] The target time period refers to the time period corresponding to the situation where the driving frequency record does not conform to the preset driving frequency interval.

[0048] Step S106: In the target time period, it is judged whether an emergency stop signal is received.

[0049] The emergency stop signal refers to a door body stop instruction triggered by safety protection or emergency during the running of the elevator door, which is usually derived from the door control emergency stop button, the fault protection signal of the door machine control module or the trigger signal of the safety sensor (such as the anti-pinch sensor).

[0050] Step S107: If not, the target time period is associated with the door body running data to determine the abnormal occurrence section.

[0051] In another aspect, if no emergency stop signal is received in the target time period, no further processing is performed on the driving frequency record in the closing step.

[0052] The door body running data refers to real-time acquisition information reflecting the running state of the layer door, including the displacement position of the layer door, the moving speed of the layer door, the acceleration of the layer door, etc.

[0053] The abnormal occurrence section refers to the position interval of the abnormal state in the door body running track determined by the association of the door body running data and the target time period, which is usually expressed in terms of displacement range or travel percentage.

[0054] Step S108: generating abnormal information corresponding to the abnormal occurrence section, and uploading the abnormal information to a maintenance platform.

[0055] The abnormal information refers to diagnostic data generated based on the abnormal occurrence section, for describing the abnormal state of the layer door, and generally includes the abnormal position, the abnormal type, the running phase, and the related door body running characteristics.

[0056] The maintenance platform refers to an elevator remote maintenance management system, which receives the abnormal data uploaded by the elevator, generates a maintenance work order, and provides abnormal diagnosis basis for maintenance personnel.

[0057] After determining the abnormal occurrence section, the position information, the running state, and the characteristic data of the section are extracted and encapsulated as abnormal information, which includes the elevator number, the floor, the abnormal section position, the running phase (start, acceleration, constant speed, deceleration, and maintenance), and the time stamp.

[0058] By adopting the above technical solution, after executing a layer door closing step, the drive frequency record of the door machine is obtained, the target drive frequency is obtained based on the drive frequency record, the target time period is obtained through the target drive frequency, and in the case where no emergency stop signal is received, the existence of the target drive frequency indicates that there is a potential running abnormal problem in the closing process of the elevator door. Therefore, the abnormal occurrence drive is determined in combination with the target time period and the door body running data, the corresponding abnormal information is generated and uploaded to the operation and maintenance platform, so that the operation and maintenance personnel can discover and make corresponding maintenance work in time, so as to realize the identification of the potential abnormality existing in the running process of the elevator door and reduce the safety hidden danger of the elevator door.

[0059] Embodiments of the present application provide a second elevator door operation and maintenance method, referring to Figure 2 The method comprises the following steps: Step S201: obtaining the drive frequency record of all floors.

[0060] Each floor has a unique floor id, and the floor id is added to the drive frequency record when the drive frequency record is obtained, so as to form the drive frequency record corresponding to the floor. By traversing all floor ids, the drive frequency record of all floors is obtained.

[0061] Step S202: mapping the drive frequency records of all floors to the same coordinate system to obtain a drive frequency distribution diagram.

[0062] The distribution diagram generated after mapping the drive frequency records collected in the door body operation process of different floors to a unified time coordinate system is used to form a drive frequency distribution diagram, and the drive frequency records of each floor are presented in the form of curves on the drive frequency distribution diagram, which is used for intuitive comparison of the drive frequency curve characteristics of each floor. The ordinate of the drive frequency distribution diagram is the drive frequency record, and the abscissa of the drive frequency distribution diagram is the time.

[0063] Step S203: Based on the drive frequency distribution diagram, it is judged whether the synchronization rate of the time period corresponding to the target drive frequency in the drive frequency record of each floor is greater than the preset synchronization rate.

[0064] The preset synchronization rate is a preset constant, which can be adjusted according to actual needs.

[0065] Based on the drive frequency distribution diagram, the abscissa of the target drive frequency of each floor is intercepted to obtain the time period corresponding to the target drive frequency, and the time period corresponding to the target drive frequency is intersected and unionized to obtain a first time period and a second time period, wherein the synchronization rate is the ratio of the first time period to the second time period. Compare the synchronization rate with the preset synchronization rate. In the case where the synchronization rate is greater than the preset synchronization rate, it indicates that the target drive frequency of each floor appears at the same time, that is, in the process of closing the door, the door machine of different floors appears in the same operation stage. Similar drive frequency anomaly, reflecting that the anomaly has the commonality of crossing floors, and it is most likely caused by the abnormality of the door moving mechanism.

[0066] Step S204: If yes, mark the time period corresponding to the target drive frequency in the drive frequency record of each floor as an abnormal time period.

[0067] In the case where the synchronization rate is greater than the preset synchronization rate, it indicates that the abnormality corresponding to the target drive frequency has consistency in multiple floors. At this time, the time period corresponding to the target drive frequency in the drive frequency record of each floor is uniformly marked as an abnormal time period. Specifically, the first time period can be used as the abnormal time period.

[0068] Step S205: Obtain the corresponding execution component information based on the abnormal time period and the door body operation data.

[0069] The abnormal time period is correspondingly mapped with the door body operation data on the time axis to determine the operation section where the door body is located when the abnormality occurs, and then according to the operation section where the door body is located, the executing component that may cause the abnormality is located in combination with the mechanical structure characteristics of the door body. For example, if the abnormal time period is located in the starting section or the accelerating section, it may be related to the door machine traction wheel, the synchronous belt or the guide wheel and the like; if the abnormal time period is located in the constant speed section, it may be related to the door body slide rail, the guide shoe or the balancing device; if the abnormal time period is located in the decelerating section or the maintaining section, it may be related to the door lock mechanism, the buffer device or the positioning device.

[0070] After the corresponding executing component is acquired, the executing component is associated with the abnormal time period and the floor id to generate the corresponding executing component information.

[0071] Step S206: The executing component information is added to the landing door abnormal information.

[0072] The purpose of adding the executing component information to the landing door abnormal information is to directly indicate the specific mechanical component (such as the driving wheel, the guide rail, the door lock mechanism and the like) corresponding to the abnormal time period, so as to help the maintenance personnel to check the corresponding component when overhauling, and to avoid invalid troubleshooting.

[0073] Step S207: If no, the elevator door abnormal information is output according to the preset detection method.

[0074] If no, it indicates that the synchronization rate of the time period corresponding to the target driving frequency in the driving frequency record of each floor is not greater than the preset synchronization rate. Based on this situation, it indicates that the time points of the abnormality of each floor are not synchronized, that is, the abnormality does not have commonality across floors, and therefore the abnormality may exist in the landing door and its associated components or the hall door and its associated components. The elevator door abnormal information includes the landing door abnormal information and the hall door abnormal information, the landing door abnormal information represents the abnormal information corresponding to the landing door and its associated components, and the hall door abnormal information represents the abnormal information corresponding to the hall door and its associated components. The specific steps of outputting the elevator door abnormal information according to the preset detection method can refer to the steps in the embodiment. Figure 5

[0075] By adopting the above technical solution, by acquiring the driving frequency records of all floors and obtaining the synchronization rate of the time period corresponding to the target driving frequency based on the driving frequency distribution diagram, in the case where the synchronization rate is greater than the preset synchronization rate, it indicates that the probability of the existence of the operation abnormality problem in each floor in the time period is relatively high, and it can be inferred that the operation abnormality problem exists in the landing door and its associated components. The executing component information when the current executing door body is moving is acquired through the abnormal time period and the door body operation data, and the executing component information is added to the landing door abnormal information, so as to facilitate the maintenance personnel to carry out targeted overhauling and maintenance, and to improve the fault handling efficiency and the elevator operation safety. ​

[0076] The embodiment of the application provides an elevator door operation and maintenance method three, referring to Figure 3 The method comprises the following steps: Step S301: determining whether the proportion of the abnormal time period in the total time period is greater than a preset time proportion.

[0077] The preset time proportion is a preset constant, which can be adjusted according to actual needs.

[0078] The abnormal time period is divided by the total time period to obtain the proportion of the abnormal time period in the total time period. The purpose of the determination is to distinguish whether the abnormality corresponding to the abnormal time period is a persistent abnormality or a local abnormality.

[0079] Step S302: if yes, marking the layer door running section corresponding to the abnormal time period as a persistent abnormal area.

[0080] The layer door running section represents the position of the layer door moving in the closing process.

[0081] If yes, it means that the proportion of the abnormal time period in the total time period is greater than the preset time proportion. Based on this condition, the starting node of the layer door at the beginning of the abnormal time period is taken as the starting point of the layer door running section, and the ending node of the layer door at the end of the abnormal time period is taken as the end point of the layer door running section. The section corresponding to the starting point to the end point is taken as the persistent abnormal area.

[0082] Step S303: generating high-warning maintenance information including a prompt to detect layer door moving mechanism abnormality according to the persistent abnormal area.

[0083] The layer door moving mechanism refers to the transmission and guiding mechanism responsible for the opening and closing of the layer door, including the door machine, the transmission belt, the door cutter, the guide rail, the cutter pulley and the like.

[0084] The high-warning maintenance information refers to the maintenance prompt information generated under the condition that the persistent abnormal area is detected, which belongs to high-priority warning, prompting the maintenance personnel to check or repair the layer door moving mechanism in priority, so as to troubleshoot possible long-term jamming, friction resistance, mechanical failure and the like.

[0085] Under the condition that the layer door running section is the persistent abnormal area, it means that there is a stability problem or long-term resistance in the layer door in the section, so it is necessary to generate high-warning maintenance information to prompt the maintenance personnel to repair.

[0086] Step S304: if no, marking the layer door running section corresponding to the abnormal time period as a local abnormal area.

[0087] If no, it means that the proportion of the abnormal time period in the total time period is not greater than the preset time proportion. Based on this condition, it means that the abnormality corresponding to the abnormal time period is a local abnormality.

[0088] The local abnormal area refers to an operation section in which the proportion of the abnormal time period to the total closing time does not exceed the preset time proportion threshold, and is usually manifested as an occasional or discontinuous abnormal phenomenon. Such an abnormality may be caused by local component wear, slight misalignment or temporary obstacles, and has a lower stability impact Step S305: According to the local abnormal area, low-warning maintenance information including prompt execution of component information and local obstacles is generated.

[0089] The low-warning maintenance information refers to information with a lower priority than the high-warning information, and is mainly used to prompt maintenance personnel to pay attention to local component wear or obstacle problems, and is suitable for arrangement for processing in regular maintenance.

[0090] Step S306: The high-warning maintenance information or the low-warning maintenance information is added to the landing door abnormal information.

[0091] After the high-warning maintenance information or the low-warning maintenance information is generated, one of the two is added to the landing door abnormal information, and the landing door abnormal information is uploaded to the operation and maintenance platform.

[0092] By adopting the above technical solution, by acquiring the proportion of the abnormal time period to the total time period, in the case where the acquired proportion is greater than the preset time proportion, it is indicated that there is a persistent abnormality, and therefore high-warning maintenance information needs to be generated for maintenance personnel to timely process and repair; and in the case where the acquired proportion is not greater than the preset time proportion, it is indicated that the existing abnormality is local and periodic, and therefore low-warning maintenance information with relatively low warning can be generated.

[0093] Embodiments of the present application provide an elevator door operation and maintenance method four, referring to Figure 4 The method comprises the following steps: Step S401: Acquire the opening door driving frequency record when the opening door step is executed.

[0094] The opening door driving frequency record refers to a sample data set of the driving frequency of the driving motor of the door machine changing with time during the execution of the opening step, and is used to reflect the running state and load characteristics of the landing door opening. The opening door driving frequency record is divided into a starting section, an acceleration section, a constant speed section, a deceleration section and a holding section.

[0095] Step S402: Acquire the target opening door driving frequency corresponding to the opening door driving frequency record according to the opening door driving frequency record.

[0096] The target opening door driving frequency can be acquired according to the acquisition of the target driving frequency, that is, it can be acquired by referring to steps S103 and S104.

[0097] Step S403: judging whether the time period corresponding to the target opening door driving frequency is same as the time period corresponding to the target frequency.

[0098] By comparing the time period corresponding to the target opening door driving frequency and the time period corresponding to the target frequency, it can be judged whether the abnormal area is the same position. Since the door body movement direction of opening door and closing door is opposite, the time period corresponding to the opening door driving frequency needs to be reversed, that is, the time period of the opening door process is mirror converted based on the total stroke of the door body movement, so as to correspond to the same spatial position with the time period of the closing process. For example, if there is an obstacle on the door rail, the target opening door driving frequency corresponding to the time period and the target frequency corresponding to the time period will be the same in the closing and opening process of the layer door.

[0099] Step S404: if yes, adding local obstacle information in the layer door abnormal information.

[0100] The local obstacle information is used to indicate the maintenance prompt information that there is an obstacle or friction abnormality in the door body running section.

[0101] If yes, it means that the time period corresponding to the target opening door driving frequency and the time period corresponding to the target frequency are the same, so the local obstacle information is added in the layer door abnormal information.

[0102] Step S405: if no, obtaining the current value of the door machine in the target time period to obtain the target current value.

[0103] If no, the time period corresponding to the target opening door driving frequency and the time period corresponding to the target frequency are not the same, that is, the probability of the fixed position of the local obstacle is low, so the current value of the door machine can be used to further judge the abnormal type.

[0104] The target current value can reflect the load state of the door machine when the driving frequency does not meet the preset driving frequency interval.

[0105] Step S406: judging whether there is an abnormal increase section in the target current value.

[0106] The abnormal increase section refers to the time section in the current curve which exceeds the preset current threshold or the slope increases exceeding the preset slope threshold, representing that the door machine load increases or encounters mechanical impedance. The preset current threshold and the preset slope threshold are both preset constants.

[0107] In the process of driving the landing door by the door machine, if there are foreign matters in the landing door track, the track is stuck, the door body is offset, or other mechanical resistance, the motor needs to output greater driving force to maintain normal running speed; since the output torque of the motor is proportional to the current, the increase of the motor driving force will directly lead to the increase of the current value, thereby showing an abnormal increase section on the current curve; at the same time, the mechanical impedance usually changes suddenly or in stages, so not only the current value will increase instantaneously, but also the slope of the current curve will increase sharply, exceeding the preset slope threshold in the normal running state.

[0108] Step S407: If yes, add local obstacle information to the landing door abnormal information.

[0109] If yes, it indicates that there is an abnormal increase section in the target current value, that is, the door machine has a sudden load increase or encounters mechanical resistance, based on which it is indicated that the probability of the existence of a local obstacle is higher, and the position of the local obstacle is not fixed, so the local obstacle information is added to the landing door abnormal information.

[0110] Step S408: If no, add door machine abnormal information to the landing door abnormal information.

[0111] If no, it indicates that there is no abnormal increase section in the target current value, that is, the landing door running abnormality problem occurs without an abnormal increase section, which indicates that the running abnormality problem is not caused by the mechanical resistance of the door body or the local obstacle, but is more likely related to the door machine. Therefore, the door machine abnormal information is generated and added to the landing door abnormal information to prompt the maintenance personnel to moderately check the door machine and its electric control components.

[0112] By adopting the above technical solution, when the door opening driving frequency is consistent with the target driving frequency time period, it indicates that the landing door is abnormal in the running process due to a local obstacle, so the local obstacle information can be added to the landing door abnormal information. When the time periods of the two are inconsistent, whether the door machine is blocked in the running process, that is, the abnormal increase section, can be judged in combination with the door machine current value. In the case of an abnormal increase section, it indicates that there is a local obstacle, so the local obstacle information is added to the landing door abnormal information. In the case of no abnormal increase section, it indicates that an abnormality occurs in the running process of the door machine, so the door machine abnormal information is added to the landing door abnormal information. This helps to improve the accuracy and pertinence of abnormal identification, helps the maintenance personnel to timely locate the specific fault components, and improves the elevator door maintenance efficiency and safety guarantee level.

[0113] Referring to Figure 5 , the step of outputting the elevator door abnormal information according to the preset detection method comprises: Step S501: Mark the floor corresponding to the target driving frequency to obtain the target floor.

[0114] In the driving frequency records of all floors, find the driving frequency record in which the target driving frequency exists, and obtain the floor id through the driving frequency record found, and according to the floor id, add the target floor label in the driving frequency record.

[0115] Step S502: Pull the driving frequency records of the target floor in the preset time period from the historical records to obtain a set of historical driving frequency records.

[0116] In another aspect, if the number of target floors is not less than the preset number of floors, that is, each floor has a running abnormal problem, which reflects that the running abnormal problem has the commonality across floors, and is most likely caused by the abnormality of the landing door and its associated components. Therefore, high warning landing door and its associated component abnormal information can be generated and added to the landing door abnormal information to prompt maintenance personnel to timely repair the landing door and its associated components.

[0117] The preset time period is a preset constant, which can be adjusted according to actual conditions.

[0118] The driving frequency records in the pre-trial time period are collected to obtain a set of historical driving frequency records, and each record in the set contains the floor id of the target floor.

[0119] Step S504: Obtain the number of occurrences of the target driving frequency based on the set of driving frequency records.

[0120] After obtaining the number of occurrences of the target frequency, it can be judged whether the running abnormal problem is a high frequency occurrence or a low frequency occurrence. If the running abnormal problem is a low frequency occurrence, it may be caused by occasional external factors, such as hall door obstacles, temporary jamming, etc.

[0121] Step S505: Determine whether the number of occurrences is less than a preset number threshold.

[0122] The preset number threshold is a preset constant, and when the number of occurrences is less than the preset number threshold, it means that the running abnormal problem is a low frequency occurrence.

[0123] Step S506: If yes, output the hall door abnormal information containing the target floor information.

[0124] If yes, it means that the number of occurrences is less than the preset number threshold, that is, the running abnormal problem is a low frequency occurrence, so it can be inferred that the cause of the running abnormal problem is related to the hall door and its associated components of the target floor. Therefore, the hall door abnormal information containing the target floor information is output to guide the maintenance personnel to repair the hall door and its associated components of the target floor.

[0125] Step S507: If no, output the abnormal information according to the preset abnormality analysis method.

[0126] If no, it indicates that the occurrence frequency is not less than the preset frequency threshold. Based on this case, there is a probability that the layer door and its associated components are abnormal, and there is also a probability that the hall door and its associated components are abnormal. Therefore, it is necessary to output abnormal information according to the preset abnormal analysis information.

[0127] By adopting the technical solution, the occurrence frequency of the target driving frequency can be obtained according to the historical driving frequency record set of the target floor. If the occurrence frequency is less than the preset frequency threshold, it indicates that the probability that the layer door and its associated components are abnormal is relatively small, and the probability that the hall door and its associated components are abnormal is relatively large. Therefore, the hall door abnormal information containing the target floor information is output. When the occurrence frequency is not less than the preset frequency threshold, the abnormality is further analyzed by the preset abnormal analysis method. This is helpful to determine the source of the running abnormal problem.

[0128] Referring to Figure 6 , the step of outputting abnormal information according to the preset abnormal analysis method comprises: Step S601: Obtain the historical driving frequency records of the adjacent floors of the target floor to obtain an adjacent historical driving frequency record set.

[0129] The adjacent floors refer to the next floor and the previous floor of the target floor. If the target floor is the top floor, the adjacent floor is the next floor of the target floor. If the target floor is the bottom floor, the adjacent floor is the previous floor of the target floor.

[0130] The historical driving records of the target floor are pulled from the historical records corresponding to the adjacent floors, and these records are collected to obtain the adjacent historical driving frequency record set.

[0131] Step S602: Obtain the concentrated time period of the occurrence of the target driving frequency based on the historical driving frequency record set.

[0132] The concentrated time period refers to the time period in which the target driving frequency is most densely distributed when the target driving frequency occurs multiple times in the historical driving frequency record set.

[0133] Map the time stamps of all target zone frequencies according to the time axis, adopt a time clustering algorithm (such as DBSCAN time interval-based clustering), identify the densely distributed time period, and take the time period as the concentrated time.

[0134] Step S603: Determine whether the deviation value between the time of the occurrence of the target driving frequency in the adjacent historical driving frequency record set and the concentrated time is greater than a preset deviation range.

[0135] The preset deviation range is a preset constant.

[0136] The time at which the target driving frequency appears in the adjacent historical driving frequency record set can be obtained according to the acquisition method of the concentrated time. The midpoint of the concentrated time and the time at which the target driving frequency appears in the adjacent historical driving frequency record set are subtracted to obtain a deviation value, and the deviation value is compared with the preset deviation range, and it is determined whether the deviation value is greater than the preset deviation range.

[0137] Step S604: If no, layer door abnormal information of the layer door and the associated components is generated.

[0138] If no, it indicates that the deviation value is not greater than the preset deviation range, that is, the generation of the running abnormal problem has synchronization between adjacent floors, and it indicates that the probability of the layer door and the associated components being abnormal is relatively high, and therefore layer door abnormal information of the layer door and the associated components is generated to prompt maintenance personnel to perform maintenance.

[0139] Step S605: If yes, hall door abnormal information containing the target floor is generated.

[0140] If yes, it indicates that the deviation value is greater than the preset deviation range, that is, the generation of the running abnormal problem does not have synchronization between adjacent floors, and therefore it can be inferred that the probability of the hall door and the associated components being abnormal is relatively high, and therefore hall door abnormal information of the hall door and the associated components is generated to prompt maintenance personnel to perform maintenance.

[0141] By adopting the above technical solution, the historical driving frequency records of adjacent floors are obtained, and if the layer door and the associated components are abnormal, the time at which the running abnormal problem occurs in the process of closing the layer door in the adjacent floors is approximately the same, that is, the deviation value is not greater than the preset deviation range, and therefore layer door abnormal information of the layer door and the associated components is generated, and otherwise, hall door abnormal information containing the target floor is generated, so as to realize positioning of the running abnormal problem.

[0142] Embodiments of the present application provide an elevator door operation and maintenance method five, referring to Figure 5 The method comprises the following steps: Step S701: The number of time periods contained in a target time period is obtained, and the number of time periods is obtained.

[0143] After obtaining the target time period, the time period included in the target time period is obtained, and the number of time periods is counted to obtain the number of time periods.

[0144] For example, the target time period is the acceleration period, the constant speed period and the deceleration period included in the total time period, and the number of time periods is 3. Further, if the start time of the target time period is within the start period, the number of time periods is 4.

[0145] Step S702: Mark the target time whose period number is greater than the preset period number, to obtain a high warning target time period.

[0146] The preset period number is a preset constant, and in this embodiment, the preset period number can be set to 3.

[0147] In the case where the period number is greater than the preset period number, it indicates that the running abnormal problem corresponding to the target time period is more serious, and therefore the target time period is defined as a high warning target time period. For the floor where the high warning target time period is located, the elevator call function should be suspended.

[0148] Step S703: Determine whether the floor corresponding to the high warning target time period is the first floor.

[0149] The first floor is the floor where the first floor of the building is located, i.e., the floor where the elevator door is opened and closed most frequently.

[0150] In the case where the determination result is yes, step S704 is executed, and in the case where the determination result is no, step S705 is executed.

[0151] Step S704: If yes, control all floors corresponding to the elevator corresponding to the high warning target time period to suspend the elevator call function.

[0152] The elevator call function refers to the function of a passenger issuing a request for a specified floor through an elevator outside call panel (such as a floor button) or an elevator control system.

[0153] If yes, it indicates that the floor corresponding to the high warning target time period is the first floor, i.e., the floor corresponding to the target driving frequency is the first floor, and since the first floor is the floor where the elevator door is opened and closed most frequently, it is necessary to control all floors corresponding to the elevator corresponding to the high warning target time period to suspend the elevator call function. For example, there is a high building with elevator 1, elevator 2, elevator 3, and elevator 4. Among them, the number of periods in the target time period of the first floor of elevator 1 is greater than the preset period number, i.e., it is a high warning target time period, and therefore the elevator call function of elevator 1 at all floors is suspended.

[0154] Step S705: If no, control the floor where the high warning target time period is located to suspend the elevator call function.

[0155] If no, it indicates that the floor corresponding to the high warning target time period is not the first floor, and therefore only the floor where the high warning target time period is located needs to be controlled to suspend the elevator call function. For example, if elevator 2 has a high warning target time period at the fourth floor, the elevator call function of elevator 2 at the fourth floor is controlled.

[0156] If no, it indicates that the floor corresponding to the high warning target time period is not the first floor, and therefore only the floor where the high warning target time period is located needs to be controlled to suspend the elevator call function. For example, if elevator 2 has a high warning target time period at the fourth floor, the elevator call function of elevator 2 at the fourth floor is controlled.By adopting the technical scheme, whether the target time period is a high-warning target time period can be determined according to the number of time periods contained in the target time period, and further, if the floor corresponding to the high-warning target time period is the first floor, the elevator call function is suspended at all floors, and if the high-warning target time period is not the first floor, the elevator call function of the floor corresponding to the high-warning target time period is suspended only, which helps to guarantee the carrying capacity of the elevator under the premise of guaranteeing the safety of passengers.
