Description

Technical Field

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

[0002] As special equipment, elevators need to be maintained regularly; generally, maintenance workers carry out maintenance according to experience and the time periods recommended by the users or the management parties. Although the selection of this time period avoids the peak elevator usage period to a certain extent, it is not very accurate in terms of control only by experience; if the judgment is inaccurate, it will cause long waiting times for passengers and long elevator riding times, resulting in a bad elevator riding experience.

[0003] Furthermore, when the maintenance personnel arrive at the scene, if the elevator is executing an elevator riding instruction, the maintenance personnel need to wait for the elevator to complete the current elevator riding instruction before entering the maintenance state, causing the elevator to be taken out of the group control; during this process, there may also be a situation where the elevator still has an elevator riding instruction but has already entered the maintenance state, increasing the risk of cancellation of the elevator riding instruction or entrapment, and further possibly causing contradictions between the maintenance personnel and the passengers due to the cancellation of the elevator riding instruction, affecting the elevator riding experience of the passengers. Therefore, how to improve the accuracy of determining the specific maintenance time point while taking into account the elevator capacity is an urgent problem to be solved at present.

[0004] In view of the problem in the related art of how to accurately determine the specific maintenance time while taking into account the elevator capacity, no effective solution has been proposed yet. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0050] The method embodiment provided in this embodiment can be executed on a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 is a hardware structure block diagram of the terminal of the elevator maintenance method provided by the embodiment of this application. As Figure 1 shown, the terminal may include one or more ( Figure 1 only one is shown in the figure) processors 102 and a memory 104 for storing data. Among them, the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those of ordinary skill in the art can understand that Figure 1 the structure shown is only schematic and does not limit the structure of the above terminal. For example, the terminal may further include more or fewer components than Figure 1 shown in the figure, or have a different configuration from Figure 1 shown.

[0051] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the elevator maintenance method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, the above-mentioned method is implemented.

[0052] The transmission device 106 is used to receive or send data via a network. The above-mentioned network includes the wireless network provided by the communication provider of the terminal. In one instance, the transmission device 106 includes a network adapter (abbreviated as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one instance, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0053] As a special equipment, the elevator needs to be maintained regularly; generally, the maintenance personnel carry out maintenance according to the experience and the time period suggested by the user or the management party. Although the selection of this time period avoids the peak elevator usage period to a certain extent, but only handled by experience, the control accuracy is not very good; if the judgment is inaccurate, it will cause the consequences of long waiting time and long riding time for passengers, and further bring a bad riding experience.

[0054] When the maintenance time judged by the maintenance personnel according to experience arrives at the elevator, if the elevator is executing a riding instruction at this time, the maintenance personnel need to wait for the elevator to complete the current riding instruction before entering the maintenance state, that is, even after the elevator is taken out of group control and no longer registers riding instructions, then carry out maintenance and inspection; this process extends the working time of the maintenance personnel to a certain extent, and at the same time, there may still be uncompleted riding instructions after entering the maintenance state, increasing the risk of cancellation of riding instructions or entrapment of passengers. Further, the cancellation of riding instructions may also trigger contradictions between the maintenance personnel and the passengers.

[0055] 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:

[0056] 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.

[0057] 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.

[0058] After the elevator control system receives the elevator maintenance instruction sent by the maintenance terminal, it determines the elevators to be maintained that need to perform maintenance operations simultaneously in the current elevator group, and obtains the historical maintenance data including the historical maintenance date and the maintenance time required for each elevator during previous maintenance operations in the elevator group; and the historical operation data of the elevator group, thereby avoiding the situation of determining the maintenance time based on the experience of maintenance personnel, elevator users or elevator management parties; determining the specific recommended maintenance time period of the elevator group according to 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 helps to improve the accuracy of determining the maintenance time of the elevator. Exemplarily, the elevators to be maintained may be elevators that have not been maintained for a long time, may also be elevators with a high usage frequency, or elevators that need to be maintained as feedback by passengers or elevators that need to be maintained regularly according to the maintenance log, which are not specifically limited herein.

[0059] Further, the historical maintenance data may further include the maintenance content and abnormal conditions that occurred during maintenance, and the target maintenance time period is determined by combining the historical maintenance data including the maintenance abnormal conditions. The historical operation data includes the total operation duration of multiple elevators in the elevator group, the operation life conditions of multiple elevators, and the historical capacity of the carriages in multiple elevators, etc., which are not specifically limited herein.

[0060] Step S220, according to the historical maintenance data and historical operation data, determine the historical maintenance time period of the elevator group within the historical maintenance date, and the historical transport capacity duration requirement of the elevator group within the historical maintenance time period.

[0061] 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 date according to the historical maintenance data of the elevator group, and determines the historical transport capacity duration requirement of the elevator group within the historical maintenance time period according to the historical operation data. The historical transport capacity duration requirement here includes the total duration required for the elevator group to execute all elevator calls within the historical maintenance time period.

[0062] Determining the target maintenance time period of the elevators to be maintained in the elevator group by combining the historical operation data and historical maintenance data of the elevator group is beneficial to reducing the communication cost and time cost including passengers, maintenance personnel, etc., improving the accuracy of determining the maintenance time, and further improving the efficiency of maintenance personnel in performing maintenance and the riding experience of passengers. Among them, the historical maintenance date and the target maintenance date may be dates determined based on a quarterly or monthly maintenance cycle, which are not specifically limited herein.

[0063] In one possible embodiment, a maintenance time model is established based on the historical maintenance data, historical operation data of the elevator group, the duration and wear of multiple elevators in the elevator group when executing elevator ride commands, etc. The maintenance time model can be determined based on a deep learning algorithm, which combines the aforementioned historical maintenance data, the models of the elevators to be maintained in the elevator group, the habits of the elevator riders in the elevator group, and the service life of the elevators, etc.; the recommended maintenance time period is inferred based on the maintenance time model.

[0064] Step S230, based on the number of elevators to be maintained in the elevator group and the maintenance time required for a single elevator, determine the total maintenance duration required for the elevators to be maintained in the elevator group.

[0065] Among them, after the elevator control system obtains the number of elevators to be maintained in the elevator group, it combines the maintenance time required for a single elevator and 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 duration required for the elevators to be maintained in the elevator group. Exemplarily, the maintenance time required for a single elevator can be determined according to the ratio of the total maintenance time of previous maintenance of the elevator group to the number of elevators that have undergone maintenance in the elevator group.

[0066] Step S240, based on the number of remaining elevators in the elevator group and the total maintenance duration required for the elevators to be maintained, determine the remaining capacity duration corresponding to the remaining capacity of the remaining elevators when the elevators to be maintained in the elevator group are in the maintenance state.

[0067] 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, according to the number of elevators to be maintained and the maintenance time required for a single elevator, the total maintenance duration required for the elevators to be maintained in the elevator group is determined. When the elevators to be maintained in the elevator group are in the maintenance state, it is also necessary to ensure that the capacity of the other remaining elevators in the elevator group except the elevators to be maintained meets the elevator ride requirements of the elevator riders. Therefore, when the elevators to be maintained in the elevator group are in the maintenance state, the remaining capacity duration corresponding to the remaining elevators needs to be determined according to the number of remaining elevators and the total maintenance duration required for the elevators to be maintained.

[0068] Furthermore, determine whether the usage duration of the elevator to be maintained exceeds the service life of the elevator. If it does not exceed, the elevator to be maintained needs to be maintained.

[0069] Determine the total maintenance duration required for the elevators to be maintained in the elevator group according to the product of the number of elevators to be maintained and the maintenance time required for a single elevator.

[0070] In one possible embodiment, the elevator maintenance method further includes: obtaining the number of groups of maintenance personnel, determining the total maintenance duration 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 according to the number of elevators to be maintained in the elevator group and the number of groups of maintenance personnel.

[0071] Wherein, 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 groups of maintenance personnel. When the elevators to be maintained in the elevator group are in the maintenance state, the remaining transport capacity duration of the remaining elevators is the product of the number of remaining elevators in the elevator group and the total maintenance duration required for the elevators to be maintained.

[0072] Exemplarily, the number of groups of maintenance personnel includes the number that can perform maintenance operations simultaneously, and can also be greater than the number of elevators to be maintained that are performing maintenance operations simultaneously. 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. Among them, the preset date including the preset maintenance date can be the date of the preset maintenance date and the A days before and after it.

[0073] Set the maintenance time required for a single elevator to be B hours, the total number of elevators in the elevator group to be D, the number of groups of maintenance personnel to be 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 date to be E. Then the total maintenance duration F of the elevator group can be calculated as: B×E / C. Further, when calculating the total maintenance duration of the elevator group, it is necessary to first judge the size of the total number of elevators D in the elevator group and the number of groups C of maintenance personnel performing maintenance operations simultaneously. Generally, the total number of elevators D is not less than the number of groups C of maintenance personnel; however, when it is judged that the total number of elevators D is less than the number of groups C of maintenance personnel, the value of the number of groups C of maintenance personnel performing maintenance operations simultaneously is set to D.

[0074] In one specific embodiment, there are a total of 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 date; the number of groups of elevator maintenance personnel is 2, and these two groups of maintenance personnel perform operations simultaneously; the number of elevators stopped for maintenance simultaneously is 2; at this time, the number of elevators corresponding to the remaining transport capacity is 3. Assuming that the maintenance time required for a single elevator is 3 hours, the total maintenance duration required for the elevators to be maintained in the elevator group is calculated as 3×4 / 2 = 6 hours at this time.

[0075] Step S250, within any continuous time period greater than or equal to the total maintenance duration required for the elevators to be maintained, if it is judged that the remaining transport capacity duration is not less than the historical transport capacity duration requirement of the elevator group within the historical maintenance time period, then confirm the time period as the target maintenance time period.

[0076] Among them, in order to ensure the continuity and efficiency of the maintenance of the elevators to be maintained in the elevator group, it is necessary to determine a maintenance time period with a duration not less than the total maintenance duration of the elevator group within a continuous time period of the total maintenance duration. At the same time, within this time period, it is judged whether the remaining transport capacity duration of the remaining elevators is not less than the historical transport capacity duration requirement of the elevator group, so as to determine whether to recommend maintenance within this time period, that is, to determine whether this time period is the target maintenance time period.

[0077] After determining the maintenance time period, control the elevators to be maintained to no longer receive, register, and execute elevator ride commands, so that the maintenance personnel can perform maintenance work on the elevators to be maintained in the elevator group during the maintenance time period, improving the efficiency and accuracy of determining the maintenance time point to avoid affecting the riding experience of the passengers.

[0078] Through the above steps, after receiving the elevator maintenance instruction sent by the maintenance terminal, obtain the historical maintenance data of the elevator group including the maintenance time required for each single elevator in the historical maintenance order, the historical operation data of the elevator group, and the number of elevators to be maintained in the elevator group, and determine the historical maintenance time period of the elevator group on the historical maintenance day and the historical transport capacity duration requirement during the elevator use process; furthermore, based on the number of elevators to be maintained and the maintenance time required for each single elevator, determine the total maintenance duration required for the elevators to be maintained. Then, based on the transport capacity situation of the current elevator group, obtain the number of remaining elevators that have not been maintained in the elevator group and the total maintenance duration required for the elevators to be maintained; when the elevators to be maintained in the elevator group are in the maintenance state, obtain the remaining transport capacity duration corresponding to the remaining transport capacity of the remaining elevators; within any continuous time period not less than the total maintenance duration required for the elevators to be maintained, if the remaining transport capacity duration of the remaining elevators is not less than the historical transport capacity duration requirement of the elevator group during the historical maintenance time period, determine this time period as the target maintenance time period, and then perform maintenance on the elevators to be maintained within the target maintenance time period and reject receiving, registering, and executing elevator ride commands, 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 transport capacity.

[0079] In the above step of determining the target maintenance time period within any continuous time period not less than the total maintenance duration required for the elevators to be maintained, if the remaining transport capacity duration of the remaining elevators is not less than the historical transport capacity duration requirement of the elevator group during the historical maintenance time period, when the target maintenance time period includes multiple time periods, based on the historical operation data, obtain the busyness degree of each elevator in the elevator group within each time period on the historical maintenance day, sort based on the busyness degree of the elevators in the elevator group, and determine the optimal time period as the target maintenance time period. Among them, the optimal time period is the time period when each elevator in the historical maintenance day is the most idle (the lowest busyness degree) among multiple time periods.

[0080] In one possible embodiment, the busyness levels of each elevator in the elevator group are obtained, that is, the running times of each elevator in the elevator group within any target maintenance period are G1, G2, G3…Gn respectively. Within any maintenance period F starting from a certain running time point in the historical elevator operation data, if the remaining elevator transport capacity duration [(D - C)×F] is greater than the transport capacity duration requirement [G1 + G2 + G3 +…+ Gn] within the historical maintenance period, then it indicates that this running period belongs to a maintenance period that can be recommended for maintenance. It should be noted that there may be one or more recommended maintenance time points, or there may be none. When there are multiple or no recommended maintenance time points, the values of the elevator transport capacity duration requirements (G1 + G2 + G3 +... + Gn) within F hours starting from a certain time point in the historical maintenance data are arranged in ascending order. According to the ascending order, the recommended priority values of different maintenance time points are set to be lower and lower.

[0081] In one embodiment, when there are multiple target maintenance periods, for example, the historical transport capacity duration requirement of the first target maintenance period is denoted as P1, the historical transport capacity duration requirement of the second target maintenance period is denoted as P2……the historical transport capacity duration requirement of the nth target maintenance period is denoted as Pn. P1, P2……Pn are sorted in ascending order. The one ranked at the top is the most recommended target maintenance period, that is, the period when the elevator group is the least busy. Conducting maintenance within this period will not affect the normal elevator rides of passengers, and greatly improves the efficiency of elevator maintenance while taking into account the elevator operation.

[0082] Assume that the maintenance duration of a single elevator is 3 hours; the product of the maintenance duration of a single elevator of 3 hours and the number of elevators not in the maintenance state represents the maximum remaining transport capacity of the remaining elevators within the maintenance period. If within any such maintenance period, the total running time of the comprehensive transport capacity requirements of all elevator running times in the historical elevator operation data, that is, G1 + G2 + G3 +... + Gn, is greater than the maximum remaining transport capacity within the maintenance period, it indicates that the elevator transport capacity is insufficient within this period, which may affect travel. The smaller the transport capacity required by the elevator, the lower the busyness level of the elevator, which is more conducive to stopping the elevator for maintenance and will not affect the normal elevator rides of passengers.

[0083] The above data can take the value of the previous data cycle or the average value of multiple previous cycles. The analysis is not expanded here.

[0084] In some of these embodiments, based on the historical operation data of the elevator group, the running idle periods of the elevator group are confirmed within the preset number of days before and / or after the historical maintenance day; within the running idle periods of the elevator group, the target maintenance periods are confirmed.

[0085] Among them, within a preset number of days before and after the historical maintenance date, according to the historical operation data of the elevator group, the operation idle time period of the elevator group is determined. The data of the operation idle time period can be obtained with the week, half-month, month, quarter, and year as the data processing cycles. Arranging the target maintenance time period within the operation idle time period of the elevator group can avoid the situation of a large number of elevator ride commands needing to be executed during the maintenance in the target maintenance time period, and further improve the elevator riding experience of passengers.

[0086] In one embodiment, for example, according to the historical operation data of the elevator group, when there are many commuting people in each elevator in the elevator group during the morning rush hour, such as the time period from 8:00 to 9:00, this time period is a busy time period, and the time period from 9:00 to 11:00 is an idle time period; from 11:00 to 13:00 at noon is a busy time period, the time period from 13:00 to 17:00 in the afternoon is an idle time period, the time period from 17:00 to 18:00 is a busy time period, and the time period from 18:00 to 8:00 the next day is an idle time period; then the target maintenance time period can be confirmed within the above-mentioned multiple idle time periods. According to the different application scenarios of specific elevators, the busy time periods and idle time periods of the elevator group are different.

[0087] In some of the embodiments, after confirming that the time period is the target maintenance time period, it includes: determining the maintenance time point when the elevator to be maintained starts maintenance within the target maintenance time period, and controlling the elevator to be maintained to stop receiving elevator ride commands at the target maintenance time point.

[0088] Among them, when on the target maintenance date, after determining the target maintenance time period within any continuous time period not less than the total maintenance duration, it is also necessary to determine the target maintenance time point when the elevator to be maintained starts maintenance, and control the elevator to be maintained to stop receiving elevator ride commands, registering elevator ride commands, and executing elevator ride commands within the target maintenance time period after this target maintenance time point.

[0089] In one possible embodiment, determining the maintenance time point when the elevator to be maintained starts maintenance within the target maintenance time period includes: sending the target maintenance time period to the maintenance terminal; determining the running time required for the elevator ride command according to the elevator ride commands currently received by the elevator to be maintained; and determining the target maintenance time point when the elevator to be maintained starts maintenance within the target maintenance time period according to the running time required for the elevator ride command.

[0090] Among them, when 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 ride commands currently received by the elevator to be maintained, and then combines the running status and required running time of the current elevator ride commands of the elevator to be maintained to determine the target maintenance time point within the target maintenance time period. This target maintenance time point is the time point at which multiple parties including the elevator control system, the passenger elevator terminal, and the maintenance terminal all determine that maintenance can start.

[0091] 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 to start the 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 feedback the confirmation information to the maintenance terminal, reducing the communication times between the maintenance personnel and the management party and reducing the workload of the maintenance personnel. After all parties determine the maintenance time point, the elevator control system can receive this set target maintenance time point, and then analyze its own operating state in combination with the registered elevator ride commands to judge the execution time of the registered elevator ride commands. Further, according to the running time and running state of the elevator ride commands in the elevator to be maintained, the target maintenance time point is determined within the target maintenance time period, which is beneficial to avoiding the coincidence of the time point for the maintenance personnel to perform elevator maintenance and the time point for the elevator riders to take the elevator, and further improving the efficiency and accuracy of elevator maintenance.

[0092] Further, in one possible embodiment, after determining the target maintenance time point for 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, controlling the elevator to be maintained to stop receiving elevator ride commands before reaching the target maintenance time point; if a maintenance signal sent by the maintenance terminal is not received before the target maintenance time point, controlling the elevator to be maintained to delay and wait for a preset time, and within the preset time of delay waiting, controlling the elevator to be maintained to stop receiving elevator ride commands, and if the elevator to be maintained does not receive a maintenance signal within the preset time of delay waiting, controlling the elevator to be maintained to start receiving elevator ride commands.

[0093] Among them, when the target maintenance time point is determined, within the maintenance time period before elevator maintenance before the target maintenance time point, it is necessary to judge whether a maintenance signal from the maintenance terminal is received to ensure whether the maintenance personnel can arrive at the site where the elevator group is located before the target maintenance time point and whether they can perform maintenance when reaching the target maintenance time point. The maintenance signal can include a signal indicating whether the maintenance personnel have arrived at the site of the elevator to be maintained, which can specifically be an elevator inspection signal or a special operation input by the elevator maintenance terminal, and no specific limitation is made here. When a maintenance signal is not received before the target maintenance time point, the time point for the elevator to be maintained to start the maintenance is appropriately extended, that is, controlling the elevator to be maintained to delay and wait for a preset time, and within the preset time of delay waiting, controlling the elevator to be maintained to stop receiving, registering elevator ride commands and executing elevator ride commands; if a maintenance signal sent by the maintenance terminal is still not received within the preset time of delay waiting, it means that the maintenance personnel really cannot start the maintenance at the target maintenance time point, so this maintenance is cancelled, and the elevator to be maintained is controlled to receive the elevator ride commands sent by the elevator riders to avoid affecting the riding experience of the elevator riders.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Optionally, after the target maintenance time point is determined, the maintenance time is prompted through devices such as in-car and / or hall displays and speakers within a time period t5 (such as 5 minutes) before the target maintenance time point, so that the user can know the start time of the maintenance in advance and reduce the friction between passengers and maintenance personnel.

[0099] For the situation where the maintenance personnel do not arrive at the elevator to be maintained before the target maintenance time point, the elevator control system can give a certain delay, that is, within a time t6 (such as 1 minute) after the preset target maintenance time point arrives, the elevator is always in a state of preparing for maintenance. If the current delay time exceeds the time t6, the elevator to be maintained is controlled to exit the state of preparing for maintenance, and the elevator to be maintained is controlled to accept new elevator ride commands and join the group control.

[0100] Optionally, the maintenance personnel are reminded through the maintenance terminal after the timeout.

[0101] The present embodiment will be described and illustrated below through specific embodiments.

[0102] In most of the existing maintenance methods, the maintenance personnel communicate and discuss with the user or the management party based on experience to further determine the maintenance time, and then arrive at the site for maintenance work during the determined maintenance time period. If the elevator on site is in an operating state, it is necessary to further wait for the elevator to be in a non-operating situation and then enter the maintenance mode to break away from the group control. In the existing maintenance methods, it is impossible to accurately find a relatively idle time period of the elevator. Blindly arriving at the site for maintenance may lead to a situation where the elevator capacity is insufficient to meet the riding demand. After arriving at the site, for an elevator that is running, the maintenance personnel need to spend a certain amount of time waiting for the elevator to complete the current elevator ride command and switch to the non-operating state, reducing the maintenance efficiency. In this specific embodiment, an elevator maintenance system is provided. Figure 3 It is the system block diagram of the elevator maintenance system provided in this specific embodiment. Refer to Figure 3 and includes 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.

[0103] Among them, the elevator control system 110 is the control system owned by the elevator, 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 communicatively connected to the Internet of Things gateway 120 to obtain elevator-related operation information and receive its control instructions. The Internet of Things gateway 120 is used to transmit elevator information to the data analysis server 130 and give the information of the data analysis server 130 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 is 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 is a module used to analyze and process relevant logic control. The storage module 133 is used to store data information, output and detection records and other data. At the same time, the data analysis server 130 is respectively connected to the maintenance terminal 140 and the user terminal 150. The maintenance terminal 140 is a device used by the maintenance staff for human-computer interaction with the system, which can obtain and input relevant information. The user terminal 150 is a device used by the user for human-computer interaction with the system, which can obtain and input relevant information.

[0104] Figure 4 is the flowchart of the assistance maintenance method provided by this specific embodiment. As Figure 4 shown, the assistance maintenance method includes the following steps.

[0105] Step S410, calculate and recommend the maintenance time.

[0106] Among them, Figure 5 is the method flowchart for determining the recommended maintenance time in this specific embodiment. As Figure 5 shown, the method for determining the recommended maintenance time includes: presetting the maintenance date and rules, and dividing the elevator groups; because there is a linkage effect among the elevators in the group and the execution tasks of each elevator are the same, the maintenance can be carried out according to the group. Then, obtain the parameter settings of the maintenance terminal, including but not limited to obtaining information such as the maintenance personnel and the pre-maintenance quantity set by the maintenance terminal; and obtain the elevator historical maintenance operation data, and calculate the recommended maintenance time period according to the elevator maintenance method in the foregoing embodiment, that is, the recommended maintenance time. Here, the target maintenance date is obtained through the preset maintenance date and rules, the pre-maintenance quantity is the number of elevators to be maintained in the foregoing embodiment, and the recommended maintenance time period is the target maintenance time period in the foregoing embodiment.

[0107] Step S420, perform preparations and maintenance before pre-maintenance.

[0108] Among them, Figure 6 is the flowchart of the pre-maintenance preparation method provided by this specific embodiment. Refer to Figure 6, before maintenance, it is first necessary to select the elevator group to be maintained, the elevator to be maintained or a specific elevator, and determine the estimated start time of maintenance. Then, it is judged whether the confirmation of the owner, i.e., the elevator rider, is required. If the owner does not agree to the maintenance when the owner's confirmation is required, this maintenance will end. 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 judges the time when the elevator to be maintained needs to be removed from the group control and does not accept new elevator ride commands according to the current capacity occupancy and historical data of the elevator group, that is, the target maintenance time period in the foregoing embodiment, and at the same time, feedbacks the processing result of the system to the maintenance terminal.

[0109] Then, enter the elevator control subroutine, detect the maintenance signal and obtain the real-time time, and then judge whether there is a maintenance signal before and after the preset maintenance time. If so, perform the maintenance. If the maintenance signal is not detected, notify the maintenance personnel of overtime and enter the delay countdown. If the maintenance signal is still not received during the delay countdown, then control the elevator to be maintained to enter the group control, continue to execute the new elevator ride command, and at the same time determine that the maintenance personnel have timed out and exited, that is, this elevator maintenance has not been executed and ends.

[0110] Further, after the pre-maintenance preparation, it is necessary to enter the elevator control subroutine. Figure 7 is the flowchart of the assistance maintenance method provided by this specific embodiment. Refer to Figure 7 , after the elevator control system receives the estimated start time of maintenance, it is necessary to obtain the existing elevator ride commands, judge the execution time of the current command according to the above process. If the execution time exceeds the estimated start time of maintenance, do not accept new control commands. If there is a new command registration request, do not accept new registration commands. Optionally, at the same time, give voice or other prompts.
