Description

Technical Field

[0001] The present invention relates to the field of intelligent device computer control technology, and in particular to an elevator energy supply control method and elevator equipment, a control device, and a storage medium. Background Art

[0002] Existing smart elevators are equipped with various functional components to optimize the user experience in the elevator. Therefore, an operation panel and multiple sensors can be set inside the elevator equipment. The action process that the elevator equipment needs to execute is formulated based on the data detected by the user from the operation panel and the sensors. In each action process of the elevator equipment, there will be corresponding functional components to respond, including traction machines, brake mechanisms, display screens, door panel drive mechanisms, etc. Based on the different number of responding functional components, the power supply voltage and power load of the elevator equipment are different. In the past, AC power with a transformer was used to power the elevator equipment, but the AC power is prone to voltage fluctuations and shocks to the elevator equipment, which affects the safe operation of the elevator.

[0003] Nickel-hydrogen batteries, as storage batteries with good performance that have been widely used in recent years, have relatively stable charging and discharging characteristics. Therefore, they can be used as energy storage modules for powering elevator equipment. The energy storage module has multiple storage batteries connected in series in sequence. The AC power forms a charging current through the adapter, which first charges each storage battery, and then the storage battery outputs power to the elevator equipment stably. However, in actual use, the charging and discharging rate of each storage battery deviates. Under long-term use, the remaining power of different storage batteries is different. When the remaining power is lower than the power threshold corresponding to the output voltage characteristic of the storage battery, the output voltage of the storage battery may be lower than the voltage rating, resulting in the power supply voltage and power load for the elevator equipment failing to meet the actual expected standards, which also affects the safe operation of the elevator. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an elevator energy supply control method and elevator equipment, a control device, and a storage medium, which reasonably allocate the storage batteries in the power storage module for charging and discharging, meet the power demand of the elevator equipment, ensure stable power supply, and improve the safety level of the elevator equipment.

[0005] According to an embodiment of the first aspect of the present invention, an elevator energy supply control method is applied to elevator equipment, wherein the elevator equipment includes a charging module, an energy storage module and a control module, wherein the energy storage module includes a plurality of storage batteries, and the control module is respectively connected to each of the storage batteries, and the control module can select N of the plurality of storage batteries to be connected in series to form a power supply series circuit, and the power supply series circuit supplies power to the elevator equipment, and the charging module is used to be connected to a power supply source, and the control module can select M of the plurality of storage batteries to be charged by the charging module, and the elevator energy supply control method includes a charge and discharge analysis step, wherein N storage batteries are selected to supply power to the elevator equipment according to the charge and discharge analysis step so that the elevator equipment completes an action process, and M storage batteries are selected to be charged during the period when the elevator equipment completes an action process, and the charge and discharge analysis step is used to select N storage batteries to supply power to the elevator equipment so that ... supply power to the elevator equipment so that the elevator equipment completes an action process, and the charge and discharge analysis step is used to select N storage batteries to supply power to the elevator equipment so that the elevator equipment completes an action process, and the charge and discharge analysis step is used to select N The electrical analysis step includes: determining the power load according to the action of the elevator equipment, and determining the number N of storage batteries that need to be put into power supply according to the power load; obtaining the remaining power of each storage battery, sorting each storage battery according to the size of the remaining power, selecting N storage batteries from large to small according to the remaining power, and connecting the selected N storage batteries in series to form a power supply series circuit; selecting M storage batteries from the remaining storage batteries for charging, judging the remaining power of each remaining storage battery with the power threshold and recording the number X of storage batteries whose remaining power is greater than the power threshold, when X is greater than M, selecting M storage batteries from the X storage batteries according to the remaining power from small to large for charging, and when X is less than M, selecting X storage batteries and selecting Y storage batteries from the storage batteries whose remaining power is greater than the power threshold for charging according to the remaining power from large to small, wherein X+Y=M.

[0006] An elevator energy supply control method according to an embodiment of the present invention has at least the following beneficial effects:

[0007] The elevator energy supply control method of the present invention first determines the power load required for the elevator equipment according to the action flow that the elevator equipment is ready to implement, thereby determining the number of storage batteries that need to be put into power supply. In order to ensure the stability of the power supply for the elevator equipment, the storage batteries are sorted according to the size of the remaining power, and N storage batteries are selected in series from large to small according to the remaining power to form a power supply series circuit. Since the selected N storage batteries have a large remaining power, it is highly likely that the output voltage fluctuation of the power storage module will not be large due to excessive power consumption during the completion of an action flow of the elevator equipment. During the completion of an action flow of the elevator equipment, the remaining storage batteries can be charged so that the storage batteries can meet the power load required for the elevator equipment to execute the action flow in the future. Since the duration of each action flow period is not too long, it is necessary to quickly allow some storage batteries to be put into power supply and use in the future action flow during this action flow. In which, when the remaining power is For each storage battery whose remaining power is greater than the power threshold, if the storage battery whose remaining power is far greater than the power threshold executes an action process in the future, it is highly likely that the output voltage fluctuation of the power storage module will not be large due to excessive power consumption. Therefore, the charging priority of the storage battery is relatively low. If X is greater than M, M storage batteries are selected from the X storage batteries according to the remaining power from small to large for charging. If X is less than M, the storage batteries with remaining power greater than the power threshold can be charged at this time. At the same time, some storage batteries with remaining power less than the power threshold can also be charged. For the storage batteries with remaining power less than the power threshold, Y storage batteries are first selected from large to small according to the remaining power to charge, and the remaining power of the Y storage batteries is increased to above the power threshold as much as possible, in order to prepare for stable power supply. This design reasonably allocates the storage batteries in the power storage module for charging and discharging, meets the power demand of the elevator equipment, ensures stable power supply, and improves the safety level of the elevator equipment.

[0008] According to some embodiments of the present invention, after an action flow of the elevator equipment is completed, the charge and discharge analysis step is re-executed, and N storage batteries and M storage batteries are selected to execute the next action flow of the elevator equipment.

[0009] According to some embodiments of the present invention, re-executing the charge and discharge analysis step also includes: after selecting N storage batteries to be connected in series to form a power supply series circuit, marking the storage batteries used to form a power supply series circuit in the previous action flow but not used to form a power supply series circuit in this action flow as pending storage batteries, and correcting the remaining power of the pending storage batteries to a virtual power value using a priority coefficient, wherein the virtual power value is less than the remaining power of the storage battery; in selecting M storage batteries from the remaining storage batteries for charging, using the virtual power value of the pending storage batteries to be determined to be judged with the power threshold; after the pending charge and discharge analysis step is completed, restoring the remaining power of the pending storage batteries to the actual remaining power value, and deleting the mark of the pending storage batteries.

The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0032] According to a first aspect of the present invention, an elevator energy supply control method is applied to an elevator device, such as Figure 3 , 4 As shown, the elevator equipment includes a charging module 110, an energy storage module 200 and a control module 120. The energy storage module 200 includes a plurality of batteries 210. The control module 120 is respectively connected to each of the batteries 210. The control module 120 can select N batteries 210 to be connected in series to form a power supply series circuit, and the power supply series circuit supplies power to the elevator equipment. The charging module 110 is used to be connected to a power supply source. The control module 120 can select M batteries 210 from the plurality of batteries 210 so that the charging module 110 can charge the M batteries 210.

[0033] Among them, the elevator equipment usually includes functional components 300 such as a traction machine, a braking mechanism, a display screen, and a door panel driving mechanism. An operation panel and multiple sensors can be set inside the elevator equipment. The action process that the elevator equipment needs to execute is formulated based on the data detected by the user from the operation panel and the sensor. In each action process of the elevator equipment, there will be corresponding functional components 300 to respond. Based on the different number of responding functional components 300, the power supply voltage and power load of the elevator equipment are different.

[0034] The charging module 110 may include a rectifier circuit, a switching power supply circuit, etc. The charging module 110 modulates the AC power into a suitable charging current to charge the battery storage module. Generally speaking, several batteries 210 are selected to be connected in series to form a charging series circuit. The charging module 110 is connected to the charging series circuit to charge each battery 210 in the charging series circuit.

[0035] The control module 120 can be selected from a processor such as an MCU or a CPU and its associated circuits. The control module is connected to the elevator equipment to obtain the power load of the elevator equipment and control the charging, discharging, switching and operation of each storage battery 210.

[0036] like Figure 1 As shown, the elevator energy supply control method includes a charge and discharge analysis step, according to which N storage batteries 210 are selected to power the elevator device so that the elevator device completes an action process, and M storage batteries 210 are selected to be charged during the elevator device completes an action process, and the charge and discharge analysis step includes:

[0037] S410, determining the power load according to the operation of the elevator equipment, and determining the number N of storage batteries 210 that need to be put into power supply according to the power load;

[0038] S420, obtaining the remaining power of each storage battery 210, sorting each storage battery 210 according to the remaining power, selecting N storage batteries 210 from large to small according to the remaining power, and connecting the selected N storage batteries 210 in series to form a power supply series circuit;

[0039] S430, select M storage batteries 210 from the remaining storage batteries 210 for charging, judge the remaining power of each remaining storage battery 210 with the power threshold and record the number X of storage batteries 210 whose remaining power is greater than the power threshold; when X is greater than M, select M storage batteries 210 from the X storage batteries 210 for charging according to the remaining power in ascending order; when X is less than M, select X storage batteries 210 and select Y storage batteries 210 from the storage batteries 210 whose remaining power is greater than the power threshold for charging according to the remaining power in descending order, wherein X+Y=M.

[0040] It should be noted that the battery 210 has an output voltage characteristic. When the remaining power of the battery 210 is greater than the power threshold, the change in the remaining power has little effect on the rated output voltage and rated output power of the battery 210. When the remaining power of the battery 210 is less than the power threshold, the change in the remaining power will cause the rated output voltage and rated output power of the battery 210 to fluctuate greatly. The power threshold is set according to the specifications of the battery 210. Therefore, for the battery 210 whose remaining power is greater than the power threshold, the number N of batteries 210 that need to be put into power supply can be determined according to the power load.

[0041] Since each action process does not last too long, it is necessary to quickly allow some of the batteries 210 to be put into use for power supply in future action processes. Therefore, during the action process, only an appropriate number of batteries 210 are selected for charging, so that the remaining power of the batteries 210 selected for charging is quickly increased.

[0042] In addition, it should be noted that, during the charging process, if a battery 210 has been fully charged, the next suitable battery 210 is selected for charging according to step S430. In addition, when the elevator does not execute the action process, the number M of the batteries 210 to be charged can be increased, and most of the batteries 210 can be charged.

[0043] The elevator energy supply control method of the present invention first determines the power load required for the elevator equipment according to the action process that the elevator equipment is ready to implement, thereby determining the number of storage batteries 210 that need to be put into power supply. In order to ensure the stability of the power supply for the elevator equipment, the various storage batteries 210 are sorted according to the size of the remaining power, and N storage batteries 210 are selected in series from large to small according to the remaining power to form a power supply series circuit. Since the selected N storage batteries 210 have a large remaining power, it is highly likely that the output voltage fluctuation of the power storage module will not be large due to excessive power consumption during the completion of an action process of the elevator equipment. During the completion of an action process of the elevator equipment, the remaining storage batteries 210 can be charged so that the storage batteries 210 can meet the power load required for the elevator equipment to execute the action process in the future. Among them, for each storage battery 210 with a remaining power greater than the power threshold, the storage battery 210 with a remaining power much greater than the power threshold in the future If an action flow is executed once, it is highly unlikely that the output voltage of the power storage module will fluctuate greatly due to excessive power consumption. Therefore, the charging priority of the storage battery 210 is relatively low. If X is greater than M, M storage batteries 210 are selected from the X storage batteries 210 for charging according to the remaining power from small to large. If X is less than M, the storage batteries 210 with a remaining power greater than the power threshold can all be charged. At the same time, some storage batteries 210 with a remaining power less than the power threshold can also be charged. For the storage batteries 210 with a remaining power less than the power threshold, first select Y storage batteries 210 for charging according to the remaining power from large to small, and try to increase the remaining power of the Y storage batteries 210 to be higher than the power threshold, in preparation for stable power supply. The design reasonably allocates the storage batteries 210 in the power storage module for charging and discharging, meets the power demand of the elevator equipment, ensures stable power supply, and improves the safety level of the elevator equipment.

[0044] In some embodiments of the present invention, when an action flow of the elevator equipment is completed, the charge and discharge analysis step is re-executed to select N storage batteries 210 and M storage batteries 210 to execute the next action flow of the elevator equipment.

[0045] Each time the elevator equipment completes an action process and is preparing to execute the next action process, the charge and discharge analysis step is re-executed, and the N storage batteries 210 for power supply and the M storage batteries 210 for charging are re-selected to ensure stable power supply during each action process. At the same time, the remaining power of each storage battery 210 is reasonably adjusted to ensure continuous and stable operation of the elevator system.

[0046] In some embodiments of the present invention, Figure 2 As shown, the re-execution of the charge and discharge analysis step also includes:

[0047] S510, after selecting N storage batteries 210 to be connected in series to form a power supply string, the storage batteries 210 used to form a power supply string in the previous action flow but not used to form a power supply string in this action flow are marked as pending storage batteries 210, and the remaining power of the pending storage batteries 210 is corrected to a virtual power value using a priority coefficient, wherein the virtual power value is less than the remaining power of the storage battery 210;

[0048] S520, in the process of selecting M storage batteries 210 from the remaining storage batteries 210 for charging, using the virtual value of the power of the storage battery 210 to be determined to be compared with the power threshold;

[0049] S530 , after the charge and discharge analysis step is completed, the remaining power of the storage battery 210 to be determined is restored to the actual remaining power value, and the mark of the storage battery 210 to be determined is deleted.

[0050] It should be noted that during the execution of the action process of the elevator equipment, the battery 210 that is put into discharge will generate heat, and the battery 210 will also generate heat during the charging process. When the battery 210 that is put into discharge is cut out from the power supply series circuit, in order to ensure its durability, the battery 210 cannot be charged immediately to prevent the battery 210 from being damaged by continuous temperature rise. After the previous action process is completed, some of the batteries 210 originally used to form the power supply series circuit in this action process will be cut out, but their remaining power is still higher than the remaining power of some batteries that are not supplying power. Therefore, it is necessary to use the priority coefficient to correct the remaining power of the battery 210 to be determined into a virtual power value, so that in the comparison process, the battery 210 to be determined is selected with a lower priority for charging.

[0051] Specifically, the situation in which the battery 210 is cut out from the power supply series circuit may be that the remaining power of the battery 210 decreases during the power supply process and is lower than the power threshold, or the remaining power of the battery 210 decreases during the power supply process, and when the charge and discharge analysis step is re-executed, the battery 210 is not selected by step S420.

[0052] In some embodiments of the present invention, re-performing the charge and discharge analysis step further includes:

[0053] Obtaining the interval time between two action processes of the elevator equipment, when the interval time is less than the time threshold, the re-execution of the charging and discharging analysis step includes:

[0054] After selecting N storage batteries 210 to be connected in series to form a power supply string, the storage battery 210 used to form a power supply string in the previous action flow but not used to form a power supply string in this action flow is marked as a pending storage battery 210, and the remaining power of the pending storage battery 210 is corrected to a virtual power value using a priority coefficient, wherein the virtual power value is less than the remaining power of the storage battery 210;

[0055] In the process of selecting M storage batteries 210 from the remaining storage batteries 210 for charging, the virtual value of the power of the storage battery 210 to be determined is used to make a judgment with the power threshold;

[0056] After the pending charge and discharge analysis step is completed, the remaining power of the pending storage battery 210 is restored to the actual remaining power value, and the mark of the pending storage battery 210 is deleted; when the interval time is greater than the time threshold, the charge and discharge analysis step is re-executed, and in the selection of M storage batteries 210 for charging from the remaining storage batteries 210, the actual remaining power of each remaining storage battery 210 is judged by using the power threshold.

[0057] When the interval between two action processes of the elevator equipment is long, even if the battery 210 used to form a power supply series circuit in the previous action process is cut out, the heat is released and the temperature is reduced accordingly. After the temperature is reduced, there is no need to lower the priority of the battery 210, and it can continue to be put into use in the next action process. Specifically, the time threshold can be set by the user or staff, and can also be set according to the heat dissipation specifications of the selected battery 210.

[0058] In some embodiments of the present invention, in correcting the remaining power of the storage battery 210 to be determined into a virtual power value using a priority coefficient, the remaining power of the storage battery 210 to be determined is multiplied by the priority coefficient to obtain the virtual power value, wherein the priority coefficient is less than 1.

[0059] In some embodiments of the present invention, the elevator energy supply control method also includes: detecting the temperature parameters of the energy storage module 200, and adjusting the value of the priority coefficient according to the temperature parameters, wherein the higher the temperature parameter, the smaller the priority coefficient, and the lower the temperature parameter, the larger the priority coefficient.

[0060] Specifically, a temperature sensor can be set on the energy storage module 200. The temperature detected by the temperature sensor can reflect the approximate temperature of the battery 210 used for power supply. When the temperature is high, it proves that the temperature of the cut-out battery 210 is also high. At this time, when executing the charge and discharge analysis step, the priority coefficient can be adjusted to a smaller value, for example, adjusted to 0.5, and the virtual value of the power is the remaining power of the to-be-determined battery 210 multiplied by the priority coefficient. Therefore, the virtual value of the power used for comparison will be set lower, and when the temperature is lower, the priority coefficient is larger, for example, 0.9. At this time, the virtual value of the power is not much different from the actual remaining power, and there is still a chance to be selected for charging.

[0061] The elevator equipment according to the second aspect of the present invention includes: a charging module 110 for connecting to a power supply; an energy storage module 200, including multiple batteries 210, wherein the batteries 210 are nickel-hydrogen batteries; a control module 120, respectively connected to each of the batteries 210, the control module 120 being used to execute the elevator energy supply control method disclosed in any of the above embodiments so as to be able to select N batteries 210 to be connected in series to form a power supply series circuit, the power supply series circuit supplies power to the elevator equipment, and to be able to select M batteries 210 from the multiple batteries 210 so as to be charged by the charging module 110.

[0062] Nickel-hydrogen batteries are storage batteries with good performance that have been widely used in recent years. They have relatively stable charge and discharge characteristics. Nickel-hydrogen batteries have strong reliability, long cycle life, up to thousands of charge and discharge cycles, fully sealed structure, low maintenance requirements, and excellent low-temperature performance.
