Description

Technical Field

[0001] The present application relates to the field of elevators, and in particular to an elevator maintenance method, an elevator control system, an electronic device and a storage medium. Background Art

[0002] As special equipment, elevators require regular maintenance. Maintenance personnel generally perform maintenance based on experience and the time periods recommended by users or managers. Although the selection of this time period avoids the peak period of elevator use to a certain extent, the control accuracy is not very good if it is based solely on experience. If the judgment is inaccurate, it will cause passengers to wait for the elevator for a long time and the passengers to take the elevator for a long time, which will bring a bad elevator experience.

[0003] Furthermore, when the maintenance personnel arrive at the scene, if the elevator is executing the elevator command, the maintenance personnel need to wait for the elevator to complete the current elevator command before entering the maintenance state, so that the elevator is out of group control; during this process, there may be a situation where the elevator still has the elevator command but has entered the maintenance state, which increases the risk of canceling the elevator command or trapping people. Further, the cancellation of the elevator command may cause conflicts between the maintenance personnel and the passengers, affecting the passengers' elevator experience. Therefore, how to improve the accuracy of determining the specific maintenance time point while taking into account the elevator's carrying capacity is a problem that needs to be solved urgently.

[0022] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 : is a hardware structure block diagram of a terminal of an elevator maintenance method provided in an embodiment of the present application. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 and a memory 104 for storing data, wherein the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA.

[0025] As special equipment, elevators require regular maintenance. Maintenance personnel generally perform maintenance based on experience and the time periods recommended by users or managers. Although the selection of this time period can avoid the peak usage period to a certain extent, the control accuracy is not very good if it is based solely on experience. If the judgment is inaccurate, it will cause passengers to wait for the elevator for a long time and take a long time in the elevator, which will further bring a bad elevator experience.

[0026] When the maintenance personnel arrive at the elevator at the maintenance time determined based on experience, if the elevator is executing an elevator command at this time, the maintenance personnel need to wait for the elevator to complete the current elevator command before entering the maintenance state, even if the elevator is out of group control and no longer registers the elevator command before performing maintenance and inspection; this process prolongs the working hours of the maintenance personnel to a certain extent, and at the same time, there may still be unfinished elevator commands after entering the maintenance state, increasing the risk of cancellation of the elevator command or entrapment of people. Furthermore, the cancellation of the elevator command may also cause conflicts between maintenance personnel and passengers.

[0027] Therefore, in order to solve the above-mentioned problem that elevator maintenance will affect the passengers' elevator experience, an elevator maintenance method is provided in an embodiment of the present application. The method combines the historical maintenance data of the elevator group and the historical operating time data of the elevator group, as well as the number of elevators to be maintained in the elevator group and the maintenance time required for a single elevator to give a recommendation for the best maintenance time period, and takes into account the elevator's carrying capacity. According to the historical operating time data of the elevator, when any continuous time period is greater than the total maintenance time required for the elevator to be maintained, and it is judged that the remaining capacity duration is not less than the historical capacity duration requirement, the time period is determined as the target maintenance time period for recommended maintenance to ensure that the remaining capacity of the elevator group can meet the passengers' elevator needs. This embodiment achieves the effect of reducing the waiting time of maintenance personnel and increasing the comfort of passengers while retaining the carrying capacity, and effectively improves the accuracy of determining the maintenance time point. The elevator maintenance method is applied to the elevator control system, and the elevator control system is connected to the maintenance terminal; Figure 2 is a flow chart of the elevator maintenance method provided in the embodiment of the present application, such as Figure 2 As shown, the process includes the following steps: Step S210, in response to receiving the elevator maintenance instruction sent by the maintenance terminal, obtain the historical maintenance data, historical operation data, and the number of elevators to be maintained in the elevator group; the historical maintenance data includes historical maintenance days and the maintenance time required for a single elevator.

[0028] Among them, when the elevator needs to be inspected and maintained, the maintenance terminal sends an elevator maintenance instruction to the elevator control system; illustratively, the elevator maintenance instruction sent by the maintenance terminal can be determined based on the cycle of historical elevator maintenance instructions, or based on the feedback from elevator passengers, which is not specifically limited here. The elevator maintenance instruction sent by the above maintenance terminal includes the target maintenance date for the elevator to be maintained. The target maintenance date can be determined by a pre-set maintenance date and set maintenance rules, or it can be determined according to relevant technical specifications, or it can be determined by negotiation between the user unit of the elevator group and the maintenance unit based on the set maintenance rules, which is not specifically limited here.

[0029] When the elevator control system receives the elevator maintenance instruction sent by the maintenance terminal, it determines the elevators to be maintained in the current elevator group that need to be maintained at the same time, and obtains the historical maintenance data of the elevator group, including the historical maintenance days and the maintenance time required for a single elevator; as well as the historical operation data of the elevator group, thereby avoiding the situation where the maintenance time is determined based on the experience of the maintenance personnel, the elevator user or the elevator manager; based on the historical maintenance data, historical operation data of the elevators to be maintained and the number of elevators to be maintained in the current elevator group, the specific recommended maintenance time period of the elevator group is determined, which helps to improve the accuracy of determining the maintenance time of the elevator. For example, the elevator to be maintained can be an elevator that has not been maintained for a long time, or it can be an elevator that is used frequently, or an elevator that is reported by passengers to need maintenance, or an elevator that needs regular maintenance according to the feedback of the maintenance log, which is not specifically limited here.

[0030] Furthermore, the historical maintenance data may also include maintenance content and abnormal conditions that occur during maintenance, and the target maintenance time period is determined in combination with the historical maintenance data including maintenance abnormalities. The historical operation data includes the total operating time of multiple elevators in the elevator group, the operating life of multiple elevators, and the historical capacity of the elevator cars in multiple elevators, etc., which are not specifically limited here.

[0031] Step S220, determining the historical maintenance time period of the elevator group within the historical maintenance day and the historical capacity duration demand of the elevator group within the historical maintenance time period according to the historical maintenance data and the historical operation data.

[0032] Among them, after the elevator control system obtains the historical maintenance data and historical operation data of the elevator group, it determines the historical maintenance time period of the elevator group within the historical maintenance day according to the historical maintenance data of the elevator group, and determines the historical capacity time requirement of the elevator group within the historical maintenance time period according to the historical operation data. The historical capacity time requirement here includes the total time required for the elevator group to execute all elevator boarding instructions within the historical maintenance time period.

[0033] Combining the historical operation data and historical maintenance data of the elevator group to determine the target maintenance time period for the elevators to be maintained in the elevator group is conducive to reducing the communication cost and time cost of elevator passengers and maintenance personnel, improving the accuracy of determining the maintenance time, and further improving the efficiency of maintenance personnel in performing maintenance and the elevator riding experience of elevator passengers. Among them, the historical maintenance day and the target maintenance day can be dates determined based on quarterly and monthly maintenance cycles, and are not specifically limited here.

[0034] In one possible embodiment, a maintenance time model is established based on the historical maintenance data of the elevator group, the historical operation data, and the duration and loss of multiple elevators in the elevator group executing elevator boarding instructions. The maintenance time model can be determined based on a deep learning algorithm, which combines the aforementioned historical maintenance data, the models of elevators to be maintained in the elevator group, the habits of passengers in the elevator group, and the service life of the elevators; based on the maintenance time model, a recommended maintenance time period is inferred.

[0035] Step S230, based on the number of elevators to be maintained in the elevator group and the maintenance time required for each elevator, determine the total maintenance time required for the elevators to be maintained in the elevator group.

[0036] Among them, after the elevator control system obtains the number of elevators to be maintained in the elevator group, it calculates the product of the number of elevators to be maintained and the maintenance time required for a single elevator, which is the total maintenance time required for the elevators to be maintained in the elevator group. For example, the maintenance time required for a single elevator can be determined based on the ratio of the total maintenance time of the elevator group to the number of elevators that have been maintained in the elevator group.

[0037] Step S240, based on the number of remaining elevators in the elevator group and the total maintenance time required for the elevators to be maintained, determine the remaining capacity time corresponding to the remaining capacity of the remaining elevators in the elevator group when the elevators to be maintained are in the maintenance state.

[0038] Among them, after determining the number of elevators to be maintained in the elevator group, the number of remaining elevators in the elevator group is determined according to the difference between the total number of elevators in the elevator group and the number of elevators to be maintained. At the same time, the total maintenance time required for the elevators to be maintained in the elevator group is determined according to the number of elevators to be maintained and the maintenance time required for a single elevator. When the elevators to be maintained in the elevator group are in maintenance status, it is also necessary to ensure that the capacity of the remaining elevators in the elevator group except for the elevators to be maintained meets the needs of passengers. Therefore, when the elevators to be maintained in the elevator group are in maintenance status, it is necessary to determine the remaining capacity time corresponding to the remaining elevators according to the number of remaining elevators and the total maintenance time required for the elevators to be maintained.

[0039] Furthermore, it is determined whether the service life of the elevator to be maintained exceeds the service life of the elevator. If not, the elevator to be maintained needs to be maintained.

[0040] The total maintenance time required for the elevators to be maintained in the elevator group is determined based on the product of the number of elevators to be maintained and the maintenance time required for a single elevator.

[0041] In one possible embodiment, the elevator maintenance method also includes: obtaining the number of groups of maintenance personnel, and determining the total maintenance time required for the elevators to be maintained in the elevator group based on the number of elevators to be maintained in the elevator group, the maintenance time required for a single elevator, and the number of groups of maintenance personnel; and determining the number of remaining elevators in the elevator group based on the number of elevators to be maintained in the elevator group and the number of groups of maintenance personnel.

[0042] The number of remaining elevators in the elevator group is determined according to the difference between the number of elevators to be maintained in the elevator group and the number of maintenance personnel. When the elevators to be maintained in the elevator group are in the maintenance state, the remaining capacity time of the remaining elevators is the product of the number of remaining elevators in the elevator group and the total maintenance time required for the elevators to be maintained.

[0043] For example, the number of groups of maintenance personnel includes the number of maintenance operations that can be performed simultaneously, and may also be greater than the number of elevators to be maintained that can be maintained simultaneously, and the number of elevators to be maintained includes the number of elevators that need to be maintained in the elevator group within a preset date. The preset date including the preset maintenance date may be the preset maintenance date and the date of A days before and after the preset maintenance date.

[0044] Assume that the maintenance time required for a single elevator is B hours, the total number of elevators in the elevator group is D, the number of maintenance personnel groups is C, and the number of elevators to be maintained in the elevator group within the preset number of days before and after the historical maintenance day is E. Then the total maintenance time F of the elevator group can be calculated and expressed as: B×E / C. Further, when calculating the total maintenance time of the elevator group, it is necessary to first determine the size of the total number of elevators D in the elevator group and the number of maintenance personnel groups C who perform maintenance operations at the same time. In general, the total number of elevators D is not less than the number of maintenance personnel groups C; however, when it is determined that the total number of elevators D is less than the number of maintenance personnel groups C, the value of the number of maintenance personnel groups C who perform maintenance operations at the same time is set to D.

[0045] In one specific embodiment, there are 5 elevators in the elevator group; there are 4 elevators to be maintained within the preset number of days before and after the historical maintenance day; the number of groups of elevator maintenance personnel is 2, and these two groups of maintenance personnel work at the same time; the number of elevators stopped for maintenance at the same time is 2; the number of elevators corresponding to the remaining capacity at this time is 3, and assuming that the maintenance time required for a single elevator is 3 hours, the total maintenance time required for the elevators to be maintained in the elevator group is calculated to be 3×4 / 2=6 hours.

[0046] Step S250, within any time period whose continuous duration is greater than or equal to the total maintenance time required for the elevator to be maintained, if it is determined that the remaining capacity duration is not less than the historical capacity duration requirement of the elevator group within the historical maintenance time period, the time period is confirmed as the target maintenance time period.

[0047] In order to ensure the continuity and efficiency of maintenance of the elevators to be maintained in the elevator group, it is necessary to determine a maintenance time period whose duration is not less than the total maintenance time of the elevator group within the continuous time period of the total maintenance time. At the same time, it is determined whether the remaining capacity duration of the remaining elevators is not less than the historical capacity duration demand of the elevator group within the time period, and then determine whether maintenance is recommended within the time period, that is, determine whether the time period is the target maintenance time period.

[0048] When the maintenance time period is determined, the elevator to be maintained is controlled to no longer receive elevator riding instructions, register elevator riding instructions, and execute elevator riding instructions, so that maintenance personnel can perform maintenance work on the elevators to be maintained in the elevator group within the maintenance time period, thereby improving the efficiency and accuracy of determining the maintenance time point to avoid affecting the elevator passengers' riding experience.

[0049] Through the above steps, after receiving the elevator maintenance instruction sent by the maintenance terminal, the historical maintenance data of the elevator group, including the maintenance time required for the historical maintenance of a single elevator, the historical operation data of the elevator group and the number of elevators to be maintained in the elevator group are obtained, and the historical maintenance time period of the elevator group on the historical maintenance day and the historical capacity time required during the use of the elevators are determined; and then based on the number of elevators to be maintained and the maintenance time required for a single elevator, the total maintenance time required for the elevators to be maintained is determined. Subsequently, based on the capacity of the current elevator group, the number of remaining elevators that have not been maintained in the elevator group and the total maintenance time required for the elevators to be maintained are obtained; when the elevators to be maintained in the elevator group are in maintenance status, the remaining capacity time corresponding to the remaining capacity of the remaining elevators is obtained; within any continuous time period that is not less than the total maintenance time required for the elevators to be maintained, if the remaining capacity time of the remaining elevators is not less than the historical capacity time requirement of the elevator group within the historical maintenance time period, the time period is determined as the target maintenance time period, and then the elevators to be maintained are maintained within the target maintenance time period, and the elevator boarding instructions are refused to be received, registered and executed, thereby ensuring the accuracy of determining the specific maintenance time point within the relatively idle time period of the elevators to be maintained while taking into account the elevator capacity.

[0050] In the above step of determining that a time period is a target maintenance time period, if the remaining capacity time of the remaining elevators is not less than the historical capacity time requirement of the elevator group in the historical maintenance time period in any continuous time period that is not less than the total maintenance time required for the elevator to be maintained, the target maintenance time period includes multiple time periods. Based on the historical operation data, the busyness of each elevator in the elevator group in each time period of the historical maintenance day is obtained, and the elevators in the elevator group are sorted based on their busyness, and the optimal time period is determined as the target maintenance time period. The optimal time period is the most idle (lowest busyness) time period of each elevator in multiple time periods on the historical maintenance day.

[0051] In one possible embodiment, the busyness of each elevator in the elevator group is obtained, that is, the running time of each elevator in the elevator group within any target maintenance time period is G1, G2, G3...Gn respectively. In any maintenance time period F after a certain running time point in the historical elevator operation data, if the remaining elevator capacity duration [(DC)×F] is greater than the capacity duration demand [G1+G2+G3+...+Gn] in the historical maintenance time period, then it means that the running time period belongs to the maintenance time period for which maintenance can be recommended. It should be noted that there may be one or more or no recommended maintenance time points. When there are multiple or no recommended maintenance time points, the values ​​of the elevator capacity duration demand (G1+G2+G3+...+Gn) within F hours after the start of the historical maintenance data from a certain time point are arranged from small to large, and the recommended priority values ​​of different maintenance time points are set to be lower and lower according to the arrangement order from small to large.

[0052] In one of the embodiments, when there are multiple target maintenance time periods, such as the historical capacity time demand of the first target maintenance time period is recorded as P1, the historical capacity time demand of the second target maintenance time period is recorded as P2... the historical capacity time demand of the nth target maintenance time period is recorded as Pn, P1, P2...Pn are sorted from small to large, and the first one is the best recommended target maintenance time period, that is, the most idle time period of the elevator group. Maintenance during this time period will not affect the normal ride of the passengers, which greatly improves the efficiency of elevator maintenance while taking into account the operation of the elevator.

[0053] Assume that the maintenance time of a single elevator is 3 hours; the product of the maintenance time of a single elevator of 3 hours and the number of elevators not in maintenance status represents the remaining maximum capacity of the remaining elevators in the maintenance time period; if in any maintenance time period, the total operating time of the comprehensive demand capacity of all elevators in the historical elevator operation data, i.e. G1+G2+G3+...+Gn, is greater than the remaining maximum capacity in the maintenance time period, it means that the elevator capacity is insufficient in this time period, which may affect travel. The smaller the capacity required by the elevator, the less busy the elevator is, and the more conducive it is to stop the elevator for maintenance, and it will not affect the normal ride of the elevator passengers.

[0054] The above data can be taken as the value of the previous data period, or as the average value of the above multiple periods, which will not be analyzed here.

[0055] In some of the embodiments, based on the historical operation data of the elevator group, the idle operation time period of the elevator group is confirmed within a preset number of days before and / or after the historical maintenance day; within the idle operation time period of the elevator group, the target maintenance time period is confirmed.

[0056] Among them, within the preset number of days before and after the historical maintenance date, the idle time period of the elevator group is determined based on the historical operation data of the elevator group. The data of the idle time period can be obtained as a data processing cycle of week, half month, month, quarter, and year. Arranging the target maintenance time period within the idle time period of the elevator group can avoid the situation where a large number of elevator boarding instructions need to be executed when performing maintenance during the target maintenance time period, further improving the elevator riding experience of the elevator passengers.

[0057] In one embodiment, according to the historical operation data of the elevator group, each elevator in the elevator group is busy during the morning rush hour, such as 8:00 to 9:00, when there are many people working, and the time period from 9:00 to 11:00 is an idle time period; 11:00 to 13:00 is a busy time period, 13:00 to 17:00 is an idle time period, 17:00 to 18:00 is a busy time period, and 18:00 to 8:00 the next day is an idle time period; the target maintenance time period can be confirmed within the above multiple idle time periods. Depending on the specific application scenario of the elevator, the busy time period and idle time period of the elevator group are different.

[0058] In some of the embodiments, after confirming that the time period is a target maintenance time period, the method includes: determining a maintenance time point for starting maintenance of the elevator to be maintained within the target maintenance time period, and controlling the elevator to be maintained to stop receiving elevator boarding instructions at the target maintenance time point.

[0059] Among them, after determining the target maintenance time period on the target maintenance day within any continuous time period that is not less than the total maintenance time, it is also necessary to determine the target maintenance time point for the elevator to be maintained to start maintenance, and control the elevator to be maintained to stop receiving elevator instructions, registering elevator instructions, and executing elevator instructions within the target maintenance time period after the target maintenance time point.

[0060] In one possible embodiment, determining a maintenance time point for starting maintenance of an elevator to be maintained within a target maintenance time period includes: sending the target maintenance time period to a maintenance terminal; determining a running time required for the elevator command according to a currently received elevator command of the elevator to be maintained; determining a target maintenance time point for starting maintenance of the elevator to be maintained within the target maintenance time period according to the running time required for the elevator command, Among them, after the elevator control system obtains the maintenance time period based on the historical maintenance data and historical operation data of the elevator group, it obtains the elevator riding instruction currently received by the elevator to be maintained, and then combines the operating status and required operating time of the elevator riding instruction of the current elevator to be maintained to determine the target maintenance time point within the target maintenance time period. The target maintenance time point is the time point when maintenance can be started, which is determined by multiple parties including the elevator control system, the elevator personnel end and the maintenance terminal.

[0061] When the elevator control system determines the target maintenance time point in the maintenance time period, it sends the maintenance time point to the maintenance terminal. After the maintenance personnel determine the target maintenance time point for starting maintenance through the maintenance terminal, the elevator control system can automatically send the maintenance time point to the user or management party for confirmation, and then feed back the confirmation information to the maintenance terminal, reducing the number of communications between the maintenance personnel and the management party and reducing the workload of the maintenance personnel. After all parties have determined the maintenance time point, the elevator control system can receive the set target maintenance time point, and then analyze its own operating status in combination with the registered elevator riding instructions to determine the execution time of the registered elevator riding instructions. Furthermore, according to the running time and running status of the elevator riding instructions in the elevator to be maintained, the target maintenance time point is determined within the target maintenance time period, which is conducive to avoiding the time point of the maintenance personnel performing elevator maintenance coincident with the time point of the elevator passengers, further improving the efficiency and accuracy of elevator maintenance.

[0062] Further, in one possible embodiment, after determining the target maintenance time point for starting maintenance of the elevator to be maintained, it includes: judging whether a maintenance signal sent by the maintenance terminal is received before the target maintenance time point; if a maintenance signal sent by the maintenance terminal is received before the target maintenance time point, the elevator to be maintained is controlled to stop receiving elevator riding instructions before reaching the target maintenance time point; if no maintenance signal sent by the maintenance terminal is received before the target maintenance time point, the elevator to be maintained is controlled to delay and wait for a preset time, and during the preset time of delayed waiting, the elevator to be maintained is controlled to stop receiving elevator riding instructions, and if the elevator to be maintained does not receive a maintenance signal within the preset time of delayed waiting, the elevator to be maintained is controlled to start receiving elevator riding instructions.

[0063] Among them, after determining the target maintenance time point, it is necessary to determine whether the maintenance signal of the maintenance terminal is received during the maintenance period before the elevator maintenance before the target maintenance time point, so as to ensure whether the maintenance personnel can arrive at the site of the elevator group before the target maintenance time point, and whether the maintenance can be performed when the target maintenance time point is reached. The maintenance signal may include a signal whether the maintenance personnel has arrived at the site of the elevator to be maintained, which may be an elevator maintenance signal or a special operation input by the elevator maintenance terminal, which is not specifically limited here. When the maintenance signal is not received before the target maintenance time point, the time point for the maintenance of the elevator to be maintained is appropriately extended, that is, the elevator to be maintained is controlled to delay the preset waiting time, and the elevator to be maintained is controlled to stop receiving, registering the elevator command and executing the elevator command during the preset delay waiting time; if the maintenance signal sent by the maintenance terminal is still not received within the preset delay waiting time, it means that the maintenance personnel cannot start the maintenance at the target maintenance time point, and the maintenance is canceled, and the elevator to be maintained is controlled to receive the elevator command sent by the elevator personnel to avoid affecting the elevator passengers' experience of taking the elevator.

[0064] Through the above steps, the target maintenance time period of the elevator to be maintained is determined according to the historical maintenance data and historical operation data of the elevator; the target maintenance time point is determined in the target maintenance time period in combination with the operation status of the elevator to be maintained and the currently registered elevator riding instructions. At the same time, it is determined whether the maintenance signal sent by the maintenance terminal is received before the target maintenance time point. If the maintenance signal sent by the maintenance terminal is received before the target maintenance time point, the passenger is refused to take the elevator during the maintenance time period after the target maintenance time point, that is, the reception, registration and execution of the elevator riding instructions are stopped. If the maintenance signal sent by the maintenance terminal is not received before the target maintenance time point, then after reaching the target maintenance time point, the elevator to be maintained is controlled to delay and wait for a preset time, and it is continuously determined whether the maintenance signal is received during the preset delay waiting time to avoid conflicts between the maintenance personnel's maintenance time and the passengers' elevator riding time, which effectively solves the problem that the maintenance time affects the passengers' elevator riding experience.

[0065] When the maintenance personnel perform maintenance before the target maintenance time point, it is necessary to ensure that the elevator to be maintained is in an offline state, that is, it is impossible to register the elevator riding instruction. Therefore, before the target maintenance time point starts, the elevator control system automatically determines the time period that does not accept new instructions based on the registered elevator riding instructions and the basic duration of the elevator riding. The elevator control system needs to determine whether it receives the maintenance signal sent by the maintenance terminal within the time period, that is, whether the maintenance personnel arrive at the elevator to be maintained before the target maintenance time point for maintenance. When the elevator control system receives the maintenance signal within the time period, it means that the maintenance personnel arrive at the elevator to be maintained on time. If the elevator control system does not receive the maintenance signal within the time period, the time period is appropriately extended, that is, the maintenance signal reception is judged within the preset time of the delayed waiting. If the maintenance signal is not received within the preset time of the delayed waiting, it is judged that the maintenance personnel is seriously late, and the normal reception, registration and operation of the elevator riding instructions for the elevator to be maintained are restored. At the beginning of the target maintenance time point, a control signal refusing to receive the elevator riding instruction is sent to the elevator to be maintained to avoid unexpected situations.

[0066] Exemplarily, the number of registered in-car commands N is set, and the execution time of the in-car commands is t2; the number of registered out-hall commands M is set, and the execution time of the out-hall commands is t3; the basic time of the elevator riding commands preset when the elevator is running is: t1, and the running time of the registered elevator riding commands is calculated to be T=t1+N×t2+M×t3.

[0067] Optionally, a fixed time period t4 may be set, and before the set maintenance start time point t4 time period (e.g., 1 minute), the system stops accepting new elevator boarding instructions, leaves group control, and enters a maintenance preparation state.

[0068] Optionally, after the target maintenance time point is determined, the maintenance time is prompted through displays, speakers and other devices inside the car and / or outside the hall during the t5 time period (e.g., 5 minutes) before the target maintenance time point, so that the user knows the maintenance start time in advance, reducing friction between passengers and maintenance personnel.

[0069] If the maintenance personnel fail to reach the location of the elevator to be maintained before the target maintenance time, the elevator control system can give a certain delay, that is, the elevator is always in the maintenance preparation state within the t6 time (such as 1 minute) after the preset target maintenance time. If the current delay time exceeds the t6 time, the elevator to be maintained is controlled to exit the maintenance preparation state, and the elevator to be maintained is controlled to accept new elevator instructions and join the group control.

[0070] Optionally, after the timeout, the maintenance personnel are reminded through the maintenance terminal.

[0071] The present embodiment is described and illustrated by means of specific examples below.

[0072] Most existing maintenance methods use maintenance personnel to communicate and discuss with users or managers based on their experience to further determine the maintenance time, and then the maintenance personnel will arrive at the site to perform maintenance work during the determined maintenance time period. If the elevator on site is in operation, it is necessary to wait until the elevator is in a non-operating state before entering the maintenance mode to exit group control. In existing maintenance methods, it is impossible to accurately find the time period when the elevator is relatively idle. Blindly arriving at the site for maintenance may result in the elevator capacity being insufficient to meet riding needs. After arriving at the site, for elevators that are in operation, maintenance personnel need to spend a certain amount of time waiting for the elevator to execute the current elevator riding command and switch to a non-operating state, reducing maintenance efficiency. In this specific embodiment, an elevator maintenance system is provided. Figure 3 is a system block diagram of the elevator maintenance system provided in this specific embodiment. Figure 3 , including an elevator control system 110, an Internet of Things gateway 120, a communication module 131, an analysis module 132, a storage module 133, a maintenance terminal 140 and a user terminal 150.

[0073] Among them, the elevator control system 110 is the elevator's own control system, which is used to collect relevant operation information, trigger instructions and other information, and send relevant operation instructions after certain logical processing. The elevator control system 110 is connected to the Internet of Things gateway 120 for communication, so that it can obtain the elevator-related operation information and accept its control instructions. The Internet of Things gateway 120 refers to the device used to transmit the elevator information to the data analysis server 130, and give the data analysis server 130 information to the elevator control system 110. The data analysis server 130 includes a communication module 131, an analysis module 132 and a storage module 133; the communication module 131 refers to a module used to communicate with the Internet of Things gateway 120, the maintenance terminal 140, and the user terminal 150. The analysis module 132 refers to a module used to analyze and process relevant logical control. The storage module 133 refers to a module used to store data information, output and detection records and other data. At the same time, the data analysis server 130 is connected to the maintenance terminal 140 and the user terminal 150 respectively. The maintenance terminal 140 refers to the device used by the maintenance personnel to interact with the system, and can obtain and input relevant information. The user terminal 150 refers to a device used by a user for human-computer interaction with the system, and can obtain and input relevant information.

[0074] Figure 4 Flowchart of the maintenance assistance method provided in this specific embodiment. Figure 4 As shown, the assisted maintenance method includes the following steps.

[0075] Step S410, calculating the recommended maintenance time.

[0076] in, Figure 5 is a flow chart of a method for determining the recommended maintenance time in this specific embodiment. Figure 5As shown, the method for determining the recommended maintenance time includes: pre-setting the maintenance date and rules, and dividing the elevators into groups; because the elevators in the group have a linkage effect and the execution tasks of each elevator are consistent, maintenance can be performed by group. Thereafter, the parameter settings of the maintenance terminal are obtained, including but not limited to obtaining the maintenance personnel set by the maintenance terminal, the number of pre-maintenance units, and other information; and the historical maintenance operation data of the elevator is obtained, and the recommended maintenance time period, i.e., the recommended maintenance time, is calculated according to the elevator maintenance method of the aforementioned embodiment. Here, the target maintenance date is obtained through the pre-set maintenance date and rules, the pre-maintenance unit quantity is the number of elevators to be maintained in the aforementioned embodiment, and the recommended maintenance time period is the target maintenance time period in the aforementioned embodiment.

[0077] Step S420, perform pre-maintenance preparation and maintenance.

[0078] in, Figure 6 This is a flowchart of the maintenance preparation method provided in this specific embodiment. Figure 6 Before maintenance, you first need to select the elevator group that needs maintenance and the elevator or specific elevator to be maintained, and determine the expected time to start maintenance. Then determine whether the owner, that is, the elevator passenger, needs to confirm. If the owner does not agree to the maintenance when the owner's confirmation is required, the maintenance will be terminated. If the owner's confirmation is not required or the owner agrees to the maintenance when the owner's confirmation is required, the elevator control system determines the time when the elevator to be maintained needs to be separated from the group control and does not accept new elevator instructions based on the current elevator group's capacity occupancy and historical data, that is, the target maintenance time period in the aforementioned embodiment, and at the same time feeds back the system's processing results to the maintenance terminal.

[0079] Afterwards, the elevator control subroutine is entered to detect the maintenance signal and obtain the real-time time, and then determine whether there is a maintenance signal before or after the preset maintenance time. If so, maintenance is carried out. If no maintenance signal is detected, the maintenance personnel is notified of the timeout and the delay countdown begins. If no maintenance signal is received during the delay countdown, the elevator to be maintained is controlled to enter group control and continue to execute new elevator boarding instructions. At the same time, it is determined that the maintenance personnel has timed out and exited, that is, the elevator maintenance has not been performed and has ended.

[0080] Furthermore, after the pre-maintenance preparation, it is necessary to enter the elevator control subroutine. Figure 7 is a flow chart of the maintenance assistance method provided in this specific embodiment. Figure 7 After the elevator control system receives the estimated maintenance start time, it will obtain the current elevator riding instructions and determine the current instruction execution time according to the above process. If the execution time exceeds the estimated maintenance start time, no new control instructions will be accepted. If there is a new instruction registration request, the new registration instruction will not be accepted. Optionally, voice or other prompts will be given at the same time.
