In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It is also to be understood that the terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when", "upon" or "in response to a determination" or "in response to a detection". Similarly, the phrase "if it is determined" or "if a [ described condition or event ] is detected" may be interpreted contextually to mean "upon determining" or "in response to determining" or "upon detecting [ described condition or event ]" or "in response to detecting [ described condition or event ]".
In particular implementations, the mobile terminals described in embodiments of the present application include, but are not limited to, other portable devices such as mobile phones, laptop computers, or tablet computers having touch sensitive surfaces (e.g., touch screen displays and/or touch pads). It should also be understood that in some embodiments, the devices described above are not portable communication devices, but are computers having touch-sensitive surfaces (e.g., touch screen displays).
In the discussion that follows, a mobile terminal that includes a display and a touch-sensitive surface is described. However, it should be understood that the mobile terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and/or joystick.

In this way, a common physical architecture (e.g., touch-sensitive surface) of the terminal can support various applications with user interfaces that are intuitive and transparent to the user.
It should be noted that in some special cases, elevators using an open loop control method are used. Compared with closed-loop control, the elevator main control board under open-loop control does not need to be connected with an encoder, so that the problem caused by encoder interference can be fundamentally avoided, and hoistway self-learning is not needed. Under the condition that the hoistway self-learning is not needed, the elevator cannot acquire floor data, relevant parameters such as acceleration and deceleration need manual setting, the parameter setting is improper, the situation of leveling or early deceleration can occur, the riding comfort is influenced, and it is important to accurately judge the floor information and automatically generate a deceleration curve through a switch (such as an inductor) in the hoistway.
Fig. 1 presents a diagrammatic view of the structure of an example of an elevator according to an embodiment of the application.
As shown in fig. 1, the elevator may include an elevator car disposed in an elevator shaft (or, an elevator shaft) in which flat bed insert boards (i.e., 110 and 140) are disposed at positions adjacent to floor slabs, respectively, it should be noted that the number of the flat bed insert boards mounted on the floor slabs may be one (i.e., single flat bed) or two (i.e., double flat bed), and in the example of fig. 1, one flat bed insert board may be disposed at each of both side positions of each floor slab, respectively.
In addition, a first magnetic shield 120 and a second magnetic shield 130 are installed on the floor of the elevator shaft, respectively, and the first magnetic shield 120 is located above the second magnetic shield 130. Specifically, the distance between the first magnetic shield 120 and the floor position above it is used to define the upward deceleration distance, i.e., the distance over which the elevator performs a deceleration operation during the upward travel. In addition, the distance between the second magnetic shield 130 and the floor position below it is used to define the descending deceleration distance, i.e. the distance at which the elevator performs a deceleration operation during descending.
In addition, a first deceleration sensor 160 for sensing the first magnetic shield 120 may be provided on the elevator car, and a first deceleration signal may be generated when the first deceleration sensor 160 senses the first magnetic shield 120. A second deceleration sensor 170 for sensing the second magnetic shield 130 may be further provided on the elevator car, and a second deceleration signal may be generated when the second deceleration sensor 170 senses the second magnetic shield 130. A level sensor (150 or 180) for sensing the level inserting plate (110 or 140) can be arranged on the elevator car, and a level sensing signal can be generated when the level sensor senses the level inserting plate.
Through this application embodiment, increase two magnetic shields at every floor of elevator well, it is used as respectively in ascending, descending speed reduction point. Meanwhile, two switches (or inductors), namely an ascending speed reducing switch and a descending speed reducing switch, can be additionally arranged on the elevator car, when the elevator car passes through an ascending speed reducing point, the ascending speed reducing switch on the elevator car acts, and when the elevator car passes through a descending speed reducing point, the descending speed reducing switch on the elevator car acts.
Fig. 2 is a block diagram showing an example of an elevator deceleration operation control system according to an embodiment of the present application.
As shown in fig. 2, the elevator deceleration running control system 200 includes a first deceleration sensor 120, a second deceleration sensor 130, a leveling sensor 210, and a controller 220. Here, the controller 220 may be various processor devices for implementing a manipulation function in the elevator, and may not limit the corresponding device type, such as an elevator main control board or other additional processing unit, etc.
Specifically, the controller 220 may obtain the elevator running direction and update the real-time elevator floor information according to the elevator running direction and the generation time for the first deceleration signal, the second deceleration signal and the landing sensing signal. Illustratively, according to the generation time of the first deceleration signal, the second deceleration signal and the landing induction signal, the generation sequence (or induction sequence) of the first deceleration signal, the second deceleration signal and the landing induction signal can be determined, and then the generation sequence can be matched with the sequence rule corresponding to the ascending or descending, and the elevator floor information is increased or decreased correspondingly when the generation sequence is matched.
Through this application embodiment, realized the elevator under open-loop control, utilized the response order of inductor, can accurately discern floor information.
In some examples of the embodiments of the present application, when the elevator traveling direction is an up direction and the leveling sensing signal, the second deceleration signal, and the first deceleration signal are sequentially generated, it is determined that the elevator car is traveling normally, and the real-time elevator floor information is increased, for example, by 1. In addition, when the elevator running direction is a descending direction and the leveling induction signal, the first deceleration signal and the second deceleration signal are sequentially generated, it is determined that the elevator car runs normally, and the real-time elevator floor information is reduced, for example, the real-time elevator floor information is reduced by 1.
In some cases, it can be determined that a fault has occurred during the operation of the elevator when the sensing signals are not generated according to a preset sequence rule or one or more signals are missing.
Specifically, in connection with the above example, when the elevator running direction is the up direction and the leveling sensing signal, the second deceleration signal and the first deceleration signal are not sequentially generated, it is determined that the elevator car is running abnormally; and when the elevator running direction is a descending direction and the leveling induction signal, the first deceleration signal and the second deceleration signal are not generated in sequence, determining that the elevator car runs abnormally. Therefore, whether the operation process of the elevator car is abnormal or not can be detected by detecting the induction signal, and the normal operation of the elevator under the open-loop control mode is ensured.
Further, when the abnormal operation of the elevator car is detected, the elevator car can be decelerated and stopped to a flat zone, then a fault is reported to indicate that the sensing equipment is possibly abnormal, and for example, an abnormal alarm notice is generated to prompt an elevator operation and maintenance personnel to maintain the elevator car.
Fig. 3 is a block diagram showing an example of an elevator deceleration operation control system according to an embodiment of the present application.
As shown in fig. 3, in step 310, the controller obtains elevator deceleration distance information, flat bed inserter length, and elevator rated speed. Here, the elevator deceleration distance information includes a distance between the deceleration sensor and an adjacent floor position. In connection with the example in fig. 1, the elevator deceleration distance information may be divided into an upward deceleration distance for the first deceleration sensor and a downward deceleration distance for the second deceleration sensor, and the corresponding elevator deceleration distance information may be obtained through a preset manner (i.e., customized by an elevator manufacturer and preset in the elevator) or a sensor detection manner. In addition, the length of the flat bed inserting plate and the rated speed of the elevator can be obtained in a preset mode.
In step 320, the controller performs a first deceleration run operation on the elevator based on the elevator deceleration distance, the flat bed inserting plate length and the elevator rated speed to decelerate the elevator car to a position sensed by the flat bed inserting plate. For example, during upward deceleration of the elevator car, the elevator car may be caused to pass a portion of the upward deceleration distance by a first deceleration running operation to reach a position that is inductive or parallel to the leveling fork strap.
In step 330, the controller performs a second slowdown operation on the elevator based on the flat bed insert plate length to stop the elevator car at a floor location of the elevator hoistway. For example, during the upward deceleration of the elevator car, the elevator car can be caused to pass through the length distance parallel to the flat bed gate in the upward deceleration distance by the second deceleration running operation.
In this application embodiment, the controller adopts different speed reduction operations at elevator deceleration in-process for the deceleration process of elevator car is more steady, can improve the comfort level of user when taking the elevator.
Fig. 4 shows a flow chart of an example of a first run-down operation of an elevator according to an embodiment of the present application.
As shown in fig. 4, in step 410, control obtains an elevator creep speed. Here, the elevator creep speed may be preset, and the controller may read the corresponding elevator creep speed.
In step 420, the controller determines corresponding first deceleration time and first deceleration acceleration information based on the elevator deceleration distance, the elevator rated speed, the elevator crawling speed and the length of the flat bed inserting plate. Illustratively, a first deceleration running distance corresponding to the first deceleration running operation can be calculated by utilizing the elevator deceleration distance and the length of the flat bed inserting plate; the first speed reduction amount corresponding to the first deceleration operation can be calculated by using the rated speed of the elevator and the crawling speed of the elevator; further, the controller may calculate a corresponding first deceleration time and first deceleration acceleration information in conjunction with the first deceleration running distance and the first speed reduction amount.
In step 430, the controller reduces the operation speed of the elevator based on the first deceleration acceleration information and controls the elevator to operate at the elevator crawling speed when the operation speed of the elevator is reduced to the elevator crawling speed. Here, the sum of the time of the deceleration operation (i.e., the elapsed time corresponding to the deceleration from the elevator rated speed to the elevator creep speed) and the time of the operation at the elevator creep speed is equal to the first deceleration time.
It should be noted that when the elevator decelerates from the rated speed of the elevator to the crawling speed of the elevator, the distance that the elevator decelerates may not be enough to reach the first deceleration running distance, and at this time, the elevator may continue to run at the crawling speed until the first deceleration time is met.
Through this application embodiment, the controller can utilize elevator relevant parameter to calculate, accomplishes first speed reduction operation fast and accurately, slows down elevator car to the position with flat bed picture peg response accurately.
Fig. 5 shows a flow chart of an example of a second run-down operation of an elevator according to an embodiment of the application.
In step 510, the controller determines a corresponding second deceleration time based on the elevator deceleration distance and the length of the leveling fork strap. For example, a correlation may be preset between the elevator deceleration distance, the length of the flat plate insert plate, and the second deceleration time, so that the controller may determine the corresponding second deceleration time by inquiring the correlation.
In step 520, the controller determines corresponding second deceleration acceleration information based on the second deceleration time and the crawling speed of the elevator. For example, deceleration acceleration information corresponding to when the crawling speed of the elevator is reduced to zero from the elevator in the second deceleration time can be calculated.
In step 530, the controller reduces the traveling speed of the elevator for a second deceleration time according to the second deceleration acceleration information.
Through this application embodiment, the controller can utilize the relevant parameter of elevator to calculate, accomplishes the second operation of slowing down fast and accurately, slows down elevator car to floor position accurately.
Fig. 6 shows a schematic diagram of an example of a deceleration profile automatically generated by a controller according to an embodiment of the application. As shown in fig. 6, the deceleration curve can be divided into a beginning rapid deceleration, a deceleration and an ending rapid deceleration. The speed reduction distance and the length of the flat plug board can be calculated automatically.
Specifically, the deceleration distance S1 and the length of the flat layer board is L1 may be preset, and the actual deceleration distance Sdec is:
sdec ═ S1-L1 equation (1)
The preset rated speed of the elevator is V1, the crawling speed is V2, when the deceleration point is effective, the elevator can decelerate from V1 to V2, and the deceleration time Tdec is:
the start section rapid deceleration Adec1 is:
and (3) rapid deceleration at an ending section: adec2 ═ Adec1
The deceleration Vdec is:
when the elevator decelerates to the creep speed V2, the deceleration is started to stop at the stop rapid deceleration Astop in the following cases.
Specifically, when a single flat floor is encountered to start decelerating and parking, the parking deceleration distance Sstop is equal to the flat floor patch length L1 × 2. When a double-flat-layer vehicle starts to decelerate and stop, the parking deceleration distance Sstop is equal to the flat-layer board inserting length L1 × 4.
The parking time Tshop is:
the stop rapid deceleration Astop is as follows:
by the above example of the calculation process, the controller can automatically generate the deceleration curve in the open loop control mode of the elevator.
