Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to a data learning method, data learning device and medium for elevator shafts. Background Technology

[0002] Existing elevator shafts or car tops are equipped with upper and lower limit switches, upper and lower forced switches, leveling signals, and other switches. These switch signals are generally transmitted to the elevator machine room via shaft cables or traveling cables.

[0003] Currently, elevators are installed even on two-story buildings. In this case, the space in the elevator pit and the space above the elevator are relatively small. When the elevator reaches the lower limit position, the elevator leveling signal is still valid. When the elevator reaches the upper limit position, the elevator leveling signal is still valid. Under these circumstances, it is difficult to accurately obtain floor data.

[0004] The common approach is to shorten the length of the elevator's magnetic shield, thereby separating the upper and lower limit positions from the effective position of the leveling signal. However, as the length of the magnetic shield is shortened, the elevator's running curve is affected, and a noticeable jerking occurs when the elevator enters the leveling position. Therefore, a better solution is urgently needed to accurately learn the elevator shaft data between two floors. Summary of the Invention

[0005] This application provides a data learning method, data learning device, and medium for elevator shafts, which can accurately learn elevator shaft data without shortening the length of the magnetic shielding plate in the case of two floors.

[0006] This application provides a data learning method for elevator shafts, applied to two floors, including:

[0007] Based on the obtained information on the length of the magnetic shielding plate in the elevator shaft, the elevator is stopped at a preset position in the leveling area of ​​the target floor between the two floors.

[0008] The elevator is controlled to run to another floor corresponding to the target floor. During the operation of the elevator, the first signal conversion of the elevator's leveling switch signal is detected to determine the departure position of the target floor.

[0009] During the operation of the elevator, the trigger position of the elevator's up and down forced switch is determined based on the signal conversion status of the elevator's up and down forced switch signal.

[0010] The arrival position on the other floor is determined by detecting the second signal transition of the elevator's leveling switch signal, where the first signal transition is different from the second signal transition.

[0011] The distance between the two floors is determined based on the departure position of the target floor and the arrival position of the other floor.

[0012] Furthermore, the target floor is the first floor, and the other floor is the second floor. Controlling the elevator to run to the other floor corresponding to the target floor includes: controlling the elevator to move upwards.

[0013] Alternatively, the target floor is the second floor, and the other floor is the first floor, and controlling the elevator to run to the other floor corresponding to the target floor includes: controlling the elevator to descend.

[0014] Furthermore, when the target floor is the first floor, the preset position for stopping the elevator at the leveling area of ​​the target floor between the two floors, based on the obtained information about the length of the magnetic shielding plate in the elevator shaft, includes:

[0015] If the length information of the magnetic shielding plate in the elevator shaft is obtained in advance, the elevator will be stopped at any position in the leveling area of ​​the target floor between the two floors.

[0016] If the length information of the magnetic shielding plate in the elevator shaft is not obtained, the elevator will be stopped at the leveling position of the target floor in the leveling area of ​​the two floors.

[0017] Furthermore, the elevator includes: a leveling switch;

[0020] When the elevator's leveling switch signal is detected to change from valid to invalid, the departure position of the target floor is determined to be half the length of the magnetic shield.

[0021] Furthermore, the step of detecting the second signal conversion of the elevator's leveling switch signal to determine the arrival position on the other floor includes:

[0022] When the elevator's leveling switch signal is detected to change from invalid to valid, the elevator's current position is taken as the arrival position for the other floor.

[0023] Furthermore, the elevator includes: an upper leveling switch and a lower leveling switch;

[0024] When the target floor is the first floor, the process of detecting the first signal transition of the elevator's leveling switch signal to determine the departure position from the target floor includes:

[0025] Based on the obtained information about the length of the magnetic shielding plate, the length of the magnetic shielding plate in the elevator shaft is obtained;

[0026] The upper and lower leveling distance is determined based on the detection of the leveling switch signal of the upper leveling switch changing from valid to invalid, and the leveling switch signal of the lower leveling switch changing from valid to invalid.

[0027] The departure position of the target floor is determined based on the length of the magnetic shielding plate and the distance between the upper and lower level floors.

[0028] Furthermore, when the target floor is the first floor, determining the trigger position of the elevator's up / down forced switch based on the signal conversion of the elevator's up / down forced switch signal includes:

[0029] When the elevator's downward forced switch signal is detected to change from valid to invalid, the current position of the elevator is used as the trigger position of the elevator's downward forced switch.

[0030] When the elevator's upward forced switch signal is detected to change from invalid to valid, the elevator's current position is used as the trigger position for the elevator's upward forced switch.

[0031] This application also provides a data learning device for elevator shafts, applied to two floors, including:

[0032] The stopping unit is used to stop the elevator at a preset position in the leveling area of ​​the target floor between the two floors, based on the obtained information on the length of the magnetic shielding plate in the elevator shaft.

[0033] The first detection unit is used to control the elevator to run to another floor corresponding to the target floor. During the operation of the elevator, it detects the first signal conversion of the elevator's leveling switch signal to determine the departure position of the target floor.

[0034] The control unit is used to determine the trigger position of the elevator's up / down forced switch based on the signal conversion status of the elevator's up / down forced switch signal during the elevator's operation.

[0035] The second detection unit is used to detect the second signal conversion status of the elevator's leveling switch signal to determine the arrival position on the other floor. The first signal conversion status is different from the second signal conversion status.

[0036] The determining unit is used to determine the floor distance between two floors based on the departure position of the target floor and the arrival position of the other floor.

[0037] This application embodiment also provides a data learning device for elevator shafts, including:

[0038] Central processing unit, memory, input / output interface, wired or wireless network interface, power supply;

[0039] The memory is either a short-term storage memory or a persistent storage memory;

[0040] The central processing unit is configured to communicate with the memory and execute instructions in the memory on a control plane functional entity to perform the methods described above.

[0041] This application also provides a computer-readable storage medium including instructions that, when executed on a computer, cause the computer to perform the method described above.

[0042] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0043] In this embodiment, based on the obtained information about the length of the magnetic shielding plate in the elevator shaft, the elevator is stopped at a preset position in the leveling zone of the target floor among two floors. The elevator is then controlled to move to the other floor corresponding to the target floor. During the elevator's operation, the first signal conversion of the elevator's leveling switch signal is detected to determine the departure position from the target floor. The elevator is then controlled to continue running from the departure position. Based on the signal conversion of the elevator's up / down forced switch signal, the trigger position of the elevator's up / down forced switch is determined. The second signal conversion of the elevator's leveling switch signal is detected to determine the arrival position of the other floor. The first signal conversion and the second signal conversion are different. Based on the departure position of the target floor and the arrival position of the other floor, the floor distance between the two floors is determined. Therefore, in this embodiment, based on the obtained information about the length of the magnetic shielding plate, data learning begins from the corresponding position. During elevator operation, the trigger position of the elevator's up / down forced switch and the floor distance between the two floors are determined by the signal conversion of the leveling switch signal and the up / down forced switch signal. In the case of two floors, there is no need to shorten the length of the magnetic shielding plate, and the elevator shaft data is accurately learned. Attached Figure Description

[0053] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0054] In the description of the embodiments of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0055] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0056] Currently, elevators are installed even on two-story buildings. In this case, the space in the elevator pit and the space above the elevator are relatively small. When the elevator reaches the lower limit position, the elevator leveling signal is still valid. When the elevator reaches the upper limit position, the elevator leveling signal is still valid. Under these circumstances, it is difficult to accurately obtain floor data.

[0057] The common approach is to shorten the length of the elevator's magnetic shield, thereby separating the upper and lower limit positions from the effective position of the leveling signal. However, as the length of the magnetic shield shortens, the elevator's running curve is affected, resulting in noticeable jerking when the elevator enters the leveling position. Therefore, this application provides a data learning method for elevator shafts that can accurately learn elevator shaft data even with only two floors, without shortening the magnetic shield length. Figure 1 As shown, the specific steps include the following:

[0058] 101. Based on the information obtained about the length of the magnetic shielding plate in the elevator shaft, the elevator is stopped at the preset position of the leveling area of ​​the target floor between the two floors.

[0059] In this embodiment of the application, when performing data learning for the elevator shaft, it is necessary to use the information on the length of the magnetic shielding plate in the elevator shaft to stop the elevator at a preset position in the leveling area of ​​the target floor between two floors. It can be understood that the target floor can be the first floor or the second floor, and the first floor is lower than the second floor in terms of floor height.

[0060] Understandably, elevators are equipped with leveling devices (position detectors) mounted on the car top. Magnetic plates are installed on the elevator shaft guide rails at each floor. When the sensor of the leveling device enters the magnetic plate, it enters the leveling zone of the target floor. Specifically, if the length of the magnetic plates in the elevator shaft is obtained beforehand, the elevator will stop at any position within the leveling zone of the target floor between the two floors. If the length of the magnetic plates is not obtained, the elevator will stop at the leveling position within the leveling zone of the target floor between the two floors.

[0061] 102. Detect the first signal conversion of the elevator's leveling switch signal to determine the departure position of the target floor.

[0062] After the elevator stops at the leveling position of the target floor between two floors, it can be controlled to move to the other floor corresponding to the target floor. During the elevator's movement, the first signal conversion of the elevator's leveling switch signal is detected to determine the departure position from the target floor. It is understandable that elevator control systems typically use one or two leveling switches for leveling control, such as... Figure 4 As shown, A is the length of the magnetic shielding plate, and B is the leveling distance between the upper and lower leveling switches; the leveling switch signal can be the switching signal of one leveling switch or the switching signal of two leveling switches, which is not limited here.

[0063] In one feasible approach, the target floor is the first floor and the other floor is the second floor. Controlling the elevator to move to the other floor corresponding to the target floor means controlling the elevator to move upward, that is, controlling the elevator to move upward from the level position of the first floor to the second floor; or, the target floor is the second floor and the other floor is the first floor. Controlling the elevator to move to the other floor corresponding to the target floor means controlling the elevator to move downward, that is, controlling the elevator to move downward from the level position of the second floor to the first floor.

[0064] The first signal transition of the leveling switch signal is generally from valid to invalid. That is, when the leveling switch is located at the position corresponding to the magnetic shield, the signal is generally valid. When the elevator moves to the moment the leveling switch leaves the magnetic shield, the signal transitions from valid to invalid. At this point, the elevator's current position can be taken as its departure position from the target floor. The current position signal can be converted into a corresponding pulse signal and recorded.

[0065] 103. Based on the signal conversion of the elevator's up and down forced switch signal, determine the trigger position of the elevator's up and down forced switch.

[0066] During elevator operation, the trigger positions of the elevator's up and down forced switch signals are determined based on the signal conversion status. It can be understood that when the target floor is the first floor and the elevator is stopped at the first floor level position, the down forced switch is active and the up forced switch is inactive; when the target floor is the second floor and the elevator is stopped at the second floor level position, the down forced switch is inactive and the up forced switch is active.

[0067] The signal transitions of the upper and lower forced switches differ when the elevator is going up or down. Specifically, during the upward movement of the elevator, the lower forced switch is triggered when it changes from an active signal to an inactive signal. That is, during normal elevator operation, when the elevator descends to this trigger position, the lower forced switch activates, causing the elevator to slow down and stop. Similarly, the upper forced switch is triggered when it changes from an active signal to an inactive signal. That is, during normal elevator operation, when the elevator ascends to this trigger position, the upper forced switch activates, causing the elevator to slow down and stop.

[0068] During the elevator's descent, the upper forced switch is triggered when it changes from a valid signal to an invalid signal; similarly, the lower forced switch is triggered when it changes from a valid signal to an invalid signal.

[0069] 104. Detect the second signal conversion status of the elevator's leveling switch signal to determine the arrival position on another floor.

[0070] During the elevator's journey to another floor, the second signal conversion status of the elevator's leveling switch signal can be detected to determine the arrival position on the other floor. The first signal conversion status is different from the second signal conversion status. Specifically, when the elevator reaches the position corresponding to the magnetic plate of the leveling switch entering the other floor, the elevator's leveling switch signal changes from invalid to valid. At this time, the elevator's current position can be taken as the arrival position on the other floor.

[0071] 105. Determine the floor distance between the two floors based on the departure position of the target floor and the arrival position of the other floor.

[0072] After determining the departure position of the target floor and the arrival position of the other floor, the floor distance between the two floors can be determined based on the departure position of the target floor and the arrival position of the other floor. The floor distance between the elevator and the arrival position of the other floor can be determined by adding the distance traveled by the elevator from the level position of the target floor to the departure position of the target floor.

[0073] As can be seen, in this embodiment, based on the obtained information about the length of the magnetic shielding plate in the elevator shaft, the elevator is stopped at a preset position in the leveling zone of the target floor among two floors; the elevator is controlled to run towards the other floor corresponding to the target floor. During the elevator's operation, the first signal conversion of the elevator's leveling switch signal is detected to determine the departure position of the target floor; the elevator is controlled to continue running from the departure position, and the trigger position of the elevator's up / down forced switch is determined based on the signal conversion of the elevator's up / down forced switch signal; the second signal conversion of the elevator's leveling switch signal is detected to determine the arrival position of the other floor, where the first and second signal conversions are different; the floor distance between the two floors is determined based on the departure position of the target floor and the arrival position of the other floor. Therefore, in this embodiment, based on the obtained information about the length of the magnetic shielding plate, data learning begins from the corresponding position. During elevator operation, the trigger position of the elevator's up / down forced switch and the floor distance between the two floors are determined by the signal conversion of the leveling switch signal and the up / down forced switch signal. In the case of two floors, there is no need to shorten the length of the magnetic shielding plate, accurately learning the elevator shaft data.

[0074] Furthermore, the elevator includes a leveling switch. Below, we will take the target floor as the first floor as an example to study the data during the elevator's upward movement. The elevator's upward movement is as follows: Figure 5 As shown, the specific data learning process is as follows: Figure 2 As shown, the specific steps include the following:

[0075] 201. Based on the information obtained about the length of the magnetic shielding plate in the elevator shaft, the elevator is stopped at the preset position of the leveling area of ​​the target floor between the two floors.

[0076] If the length information of the magnetic shielding plate in the elevator shaft is not obtained, the elevator will stop at the leveling position of the first floor of the two-story building. The elevator can be accurately stopped at the leveling position of the first floor through maintenance operation, and the shaft will perform self-learning from this leveling position to set the elevator's current height information to zero.

[0077] If the length information of the magnetic shielding plate inside the elevator shaft is obtained in advance, the elevator can be stopped at the leveling position of the first floor (1st floor) between two floors. This means controlling the elevator to descend slowly to the first floor. When the elevator's downward forced switch is detected to be valid, and the leveling switch signal is also valid, the elevator decelerates and stops at the leveling position of the first floor. At this time, the elevator's leveling switch position is as follows: Figure 5 As shown in Figure A, the elevator's leveling switch is located in the middle of the magnetic shielding plate on the first floor.

[0078] 202. Based on the detection of the elevator's leveling switch signal changing from valid to invalid, determine the departure position of the first floor.

[0079] The elevator is controlled to move from the first floor (leveling position) to the second floor (2nd floor). During the elevator's ascent, the departure position from the first floor is determined by detecting the elevator's leveling switch signal changing from valid to invalid. Specifically, the length of the magnetic shielding plate in the elevator shaft can be obtained based on the acquired information. The elevator is controlled to move upwards according to the shaft's self-learning speed. When the elevator's leveling switch signal changes from valid to invalid, the departure position from the target floor is determined to be half the length of the magnetic shielding plate. That is, the elevator's current position is initialized to half the length of the magnetic shielding plate, and the current position signal is converted into an encoder pulse signal. The elevator's leveling switch position is as follows: Figure 5 The B figure in the diagram is shown.

[0080] The length of the magnetic shield in the elevator shaft can be obtained in advance, or if the length of the magnetic shield in the elevator shaft is not obtained, when the elevator's leveling switch signal is detected to change from a valid signal to an invalid signal, twice the current height information of the elevator can be used as the length of the magnetic shield. The specifics are not limited here.

[0081] 203. Determine the trigger positions of the upper and lower forced switches based on the signal conversion.

[0082] When the elevator stops at the level position on the first floor, it is stopped by the lower forced switch. At this time, the signal of the lower forced switch is valid, and the signal of the upper forced switch is invalid. The trigger positions of the upper and lower forced switches can be determined based on the signal transition. Specifically, when the lower forced switch signal changes from valid to invalid, the current position of the elevator is used as the trigger position for the lower forced switch; similarly, when the upper forced switch signal changes from invalid to valid, the current position of the elevator is used as the trigger position for the upper forced switch.

[0083] 204. Based on the detection of the elevator's leveling switch signal changing from invalid to valid, determine the arrival position of the second floor.

[0084] During the elevator's ascent, the arrival position on the second floor is determined by detecting the elevator's leveling switch signal changing from invalid to valid. Specifically, when the elevator's leveling switch signal changes from invalid to valid, the current position of the elevator is taken as the arrival position on the other floor, and the position signal of that arrival position can be obtained. At this time, the elevator's leveling switch position is as follows: Figure 5 The C-figure is shown in the diagram.

[0085] 205. Based on the departure position of the first floor and the arrival position of the second floor, determine the floor distance between the two floors.

[0086] In this embodiment, the distance between two floors can be determined based on the departure position of the first floor and the arrival position of the second floor. Specifically, when the elevator travels from the level position of the first floor to the departure position of the first floor, the distance traveled by the elevator is half the length of the magnetic shielding plate; the position signal corresponding to the arrival position of the second floor plus the distance signal corresponding to half the length of the magnetic shielding plate can be used as the floor height signal from the first floor to the second floor.

[0087] In one feasible method, after the elevator reaches the second floor, it continues to travel half the length of the magnetic shield, then decelerates and stops at the second floor level. The elevator's leveling switch position is as follows: Figure 5 As shown in position D. If the position of the up / down forced switch is not learned during the elevator's upward movement, an up / down forced switch fault will be reported. The floor height signal corresponding to the floor distance between two floors, as well as the position signal corresponding to the up / down forced switch, can be stored in the elevator control system for later use.

[0088] Understandably, when the target floor is the second floor, the signal transition of the leveling switch corresponds to the elevator's upward movement when learning data during the elevator's descent. Specifically, during the elevator's descent, when the elevator's leveling switch signal is detected to change from valid to invalid, the elevator's current position is determined as the departure position from the target floor; when the elevator's leveling switch signal is detected to change from invalid to valid, the elevator's current position is taken as the arrival position for another floor.

[0089] Furthermore, the elevator includes two leveling switches: an upper leveling switch and a lower leveling switch. Below, we will take the target floor as the first floor as an example to study the data during the elevator's upward movement. The elevator's upward movement is as follows... Figure 6 As shown, the specific data learning process is as follows: Figure 3 As shown, the specific steps include the following:

[0090] 301. Based on the information obtained about the length of the magnetic shielding plate in the elevator shaft, the elevator is stopped at a preset position in the leveling area of ​​the target floor between the two floors.

[0091] It is understandable that step 301 is similar to step 201 above, and will not be described in detail here.

[0092] 302. Based on the first signal conversion status of the upper and lower leveling switches in the detection elevator, determine the departure position of the first floor.

[0093] The elevator is controlled to move upwards according to the self-learning speed of the shaft. During the upward movement, the departure position of the first floor is determined based on the signal transition of the upper and lower leveling switches. Specifically, the length of the magnetic shielding plate in the elevator shaft can be obtained based on the acquired information; the distance between the upper and lower leveling switches is determined based on the signal transition from valid to invalid. Furthermore, when the upper leveling switch signal transitions from valid to invalid, a pulse counting unit is activated to start counting; when the lower leveling switch signal transitions from valid to invalid, counting stops, and the count value is converted into the length signal of the distance between the upper and lower leveling switches.

[0094] Based on the length of the magnetic shielding plate and the vertical leveling distance, the departure position of the elevator is determined. That is, the current position of the elevator can be initialized to the vertical leveling distance A + half the length of the magnetic shielding plate B, i.e., (A+B) / 2, and the current position signal is converted into a pulse signal. At this time, the elevator's leveling switch position is as follows: Figure 6 As shown in Figure A.

[0095] It is understandable that when the length of the magnetic shielding plate is not obtained, the current height information of the elevator can be subtracted from the distance of B / 2 and multiplied by 2 to obtain the length of the magnetic shielding plate when the leveling switch signal of the lower leveling switch changes from signal valid to signal invalid.

[0096] 303. Determine the trigger positions of the upper and lower forced switches based on the signal conversion.

[0097] It is understandable that step 303 is similar to step 203 above, and the specifics will not be repeated here.

[0098] 304. Based on the second signal conversion status of the upper leveling switch in the detection elevator, determine the arrival position of the second floor.

[0099] Understandably, when the elevator travels from the departure position on the first floor to the second floor, the arrival position on the second floor can be determined by detecting the change in the second signal of the elevator's leveling switch. Specifically, when the leveling switch signal changes from invalid to valid, the elevator's current position is determined to be the arrival position on the second floor, and the position signal of the arrival position is obtained. The corresponding arrival position on the second floor is as follows: Figure 6 The C-figure is shown in the diagram.

[0100] 305. Based on the departure position of the first floor and the arrival position of the second floor, determine the floor distance between the two floors.

[0101] In this embodiment, when the elevator reaches the departure position, the corresponding departure distance is (A+B) / 2. The position signal at the arrival position can be added to the signal corresponding to this departure distance to obtain the floor height signal from the first floor to the second floor. When the elevator reaches the arrival position on the second floor, it can continue to travel upwards for a departure distance of (A+B) / 2 before decelerating and stopping at the level position on the second floor. Figure 6 As shown in position D.

[0102] In one feasible approach, when the target floor is the second floor, the process of learning data during the elevator's descent is similar to the process described above for the descent, and will not be elaborated further here.

[0103] This application also provides a data learning device for elevator shafts, applicable to two floors, such as... Figure 7 As shown, it includes:

[0104] The stopping unit 701 is used to stop the elevator at a preset position in the leveling area of ​​the target floor between two floors based on the obtained information on the length of the magnetic shielding plate in the elevator shaft.

[0105] The first detection unit 702 is used to control the elevator to run to another floor corresponding to the target floor. During the operation of the elevator, it detects the first signal conversion of the elevator's leveling switch signal to determine the departure position of the target floor.

[0106] Control unit 703 is used to determine the trigger position of the elevator's up and down forced switch based on the signal conversion status of the elevator's up and down forced switch signal during the operation of the elevator.

[0107] The second detection unit 704 is used to detect the second signal conversion status of the elevator's leveling switch signal to determine the arrival position of the other floor. The first signal conversion status is different from the second signal conversion status.

[0108] The determining unit 705 is used to determine the floor distance between two floors based on the departure position of the target floor and the arrival position of the other floor.

[0109] This application embodiment also provides a data learning device 800 for elevator shafts, such as... Figure 8 As shown, the data learning device 800 of this application embodiment may include one or more central processing units (CPUs) 801 and a memory 802, wherein the memory 802 stores one or more applications or data.

[0110] The memory 802 can be volatile or persistent storage. The program stored in the memory 802 can include one or more modules, each module including a series of instruction operations on the electronic device.
