- this embodiment of the present disclosure provides a shelf, including a shelf body 200, a drive mechanism 100, and a limiting mechanism.
- the drive mechanism 100 includes a motor 101 and a gear assembly to drive the shelf body 200 to move.
- the gear assembly includes a target gear 105, and a trigger portion is provided on the target gear 105.
- the limiting mechanism includes a micro switch 104.
- the micro switch 104 contacts the target gear 105. When the target gear 105 rotates, causing the micro switch 104 to contact the trigger portion 151 (152), the micro switch 104 is triggered, causing the output signal of the micro switch 104 to change and output a limiting signal.
- the gear assembly of the drive mechanism includes a transmission gear 102 and an output gear 103; the transmission gear 102 is connected to the output shaft of the motor 101 and the output gear 103, and the rotation of the output gear 103 drives the shelf body 200 to move.
- the transmission gear 102 and the output gear 103 mesh and rotate in sequence.
- Both the transmission gear 102 and the output gear 103 can be used as the target gear 105, and the target gear can be selected based on requirements.
- the gear that rotates exactly one revolution when the shelf moves from one extreme position to another can be used as the target gear.
- the microswitch is only triggered when the extreme position is reached, making it easy to determine whether the shelf has reached the extreme position based on the trigger signal output by the microswitch.
- the micro switch 104 of the limiting mechanism is positioned on the opposite side of the end face where the trigger portion of the target gear 105 is located, so that the micro switch 104 contacts the end face of the target gear 105.
- the end face of the target gear refers to the two faces perpendicular to the gear axis.
- the contact between the micro switch and the end face of the target gear includes direct contact or indirect contact. Indirect contact means that there is a contact element between the micro switch and the target gear. Understandably, when the micro switch directly contacts the end face of the target gear, the micro switch is installed on the opposite side of the end face of the target gear and abuts against the trigger portion on the end face.
- the micro switch When the micro switch indirectly contacts the end face of the target gear, the micro switch is installed on the opposite side of the end face of the target gear, and the micro switch and the target gear are offset, with indirect contact via a connecting element. In indirect contact, because the micro switch and the target gear are offset, the micro switch can be installed on the outside of the target gear, making installation easier and more convenient.
- the target gear 105 is provided with a trigger part 151 (152).
- the target gear rotates and the trigger part contacts the micro switch, the micro switch 104 is triggered.
- the target gear is provided with a protrusion 152, which serves as the trigger part (i.e., when the target gear rotates to the point where the micro switch contacts the protrusion and is triggered, it indicates that the shelf body has moved to its limit position).
- the micro switch is in the on state.
- the protrusion triggers the micro switch, causing the micro switch to change from the on state to the off state. In this way, it is possible to determine whether the shelf has been raised or lowered to its limit position based on the output signal of the micro switch.
- the position of the trigger part on the target gear depends on the limit position and the size of the target gear.
- the shelf provided in this embodiment uses a gear of the drive mechanism as the target gear, and a triggering part is provided on the target gear.
- a micro switch is provided that contacts the target gear. When the target gear rotates, the micro switch is triggered by the triggering part, and the micro switch outputs a limit signal. The position of the shelf body is determined by the limit signal. In this way, the limit position of the shelf body can be detected by a single micro switch, reducing costs and the size of the electric components of the shelf.
- the lifting stroke generated by one revolution of the target gear 105 is greater than or equal to the stroke of the shelf body from the first limit position to the second limit position.
- the gear whose theoretical lifting stroke of the shelf body is greater than or equal to the maximum stroke of the shelf body when it rotates one revolution is designated as the target gear.
- the theoretical lifting stroke of the shelf body refers to the distance the shelf body travels from its current position to the position reached after one revolution of the target gear, without considering the limitations of extreme positions.
- the maximum stroke of the shelf body refers to the distance the shelf body travels from one extreme position to another (i.e., the distance from the first extreme position to the second extreme position, or the distance from the second extreme position to the first extreme position). Understandably, when the lifting stroke corresponding to one revolution of the target gear equals the maximum stroke, only one trigger position needs to be set on the target gear.
- the triggering part includes a first protrusion 152 and/or a groove 151 disposed on the end face of the target gear 105.
- the first protrusion 152 or the groove 151 contacts the micro switch.
- the trigger part when there is only one trigger part on the target gear, the trigger part can be either a first protrusion or a groove.
- the output signal of the micro switch remains in its initial state (e.g., the micro switch remains in the open state) when the target gear rotates and causes the micro switch to spring up due to the groove.
- the state of the micro switch changes from the open state to the on state, and the output signal jumps to output a limit signal.
- the two trigger parts correspond to the upper and lower limit positions, respectively.
- Both trigger parts can be first protrusions, or both can be grooves, or one trigger part can be a groove and the other a first protrusion.
- the micro switch and the target gear are in contact via a connector, which includes a support rod 111 and a movable rod 112.
- the support rod 111 is fixedly installed.
- the movable rod 112 is movably connected to the support rod 111.
- the upper end face of the first end of the movable rod 112 is provided with a second protrusion 114, which contacts the target gear 105; the lower end face of the first end is connected to an elastic component 113; the second end of the movable rod 112 contacts the micro switch 104.
- the second protrusion of the movable rod 112 contacts the trigger position 151/152, causing the second end of the movable rod to press down to trigger the micro switch, or causing the second end of the movable rod to lift up under the action of the elastic component to trigger the micro switch.
- the connector includes a support rod, a movable rod, and an elastic component.
- the support rod is fixedly installed, and the movable rod is movably installed on the support rod.
- the second end of the movable rod contacts the micro switch, and the first end is connected to one end of the elastic component, with a second protrusion on the end face of the first end that contacts the target gear; the other end of the elastic component is fixed.
- the first protrusion 152 When the target gear 105 rotates, causing the first protrusion 152 to contact the second protrusion 114 of the movable rod 112, the first protrusion 152 exerts a downward pressure force on the first end of the movable rod 112 (i.e., the end where the second protrusion is located), compressing the elastic component 113. At this time, the second end of the movable rod 112 lifts up, breaking contact with the micro switch 104. Therefore, the micro switch 104 can change from the on state to the off state, and the output signal changes to output a limit signal.
- the elastic component is a support spring.
- the second end of the movable rod presses down to trigger the micro switch 104, causing the micro switch 104 to change from the off state to the on state, and the output signal changes.
- the output signal of the micro switch changes with the rotation of the target gear, thereby determining whether the shelf body has reached its limit position.
- this disclosure provides a method for controlling a shelf, including:
- S101 receives the lifting and lowering command for the shelf.
- the shelf body upon receiving a lifting command for the shelf, it is first determined whether it is the first control command. If it is the first time the lifting command is received, the shelf body is controlled to execute this lifting command. This is because the shelf is in its initial state when it leaves the factory, and the shelf body is not in its limit position when the lifting command is executed for the first time. If it is not the first time the lifting command is received, the shelf may be in its limit position after the last lifting. This lifting command may cause the shelf to continue moving beyond the limit position, causing damage. Therefore, in this case, the historical record information of the last lifting is obtained.
- the historical record information includes the position information of the shelf body.
- the historical record information includes the output signal and drive signal of a micro switch (the drive signal corresponds to the rise or fall command). In this way, the output signal and drive signal can be used to determine whether the shelf body is in its limit position. If it is in its limit position, the shelf may not execute this lifting command. In other embodiments, the historical record information includes the lifting position information of the shelf, that is, it includes records of the shelf rising/falling to the corresponding limit position.
- the shelf's limit positions include an upper limit and a lower limit. If historical data indicates the shelf is at its upper limit, and the current lifting command is an upward command, executing it would risk damaging the shelf; therefore, the command is not executed in this case. However, if the current lifting command is a downward command, it is determined to execute. Similarly, if historical data indicates the shelf is at its lower limit, and the current lifting command is a downward command, it is determined not to execute. However, if the current lifting command is an upward command, it is determined to execute. Furthermore, if historical data indicates the shelf is not at its limit, the lifting command is determined to execute.
- the shelf is controlled to execute the command.
- the control method for a shelf acquires historical information about the previous lifting/lowering operation when the shelf is not executing a lifting/lowering command for the first time. Based on the historical information and the current lifting/lowering command, it is determined whether there is a risk of damage. If not, the shelf body is controlled to lift/lower. In this way, it determines whether the shelf is at its limit position based on historical information, thereby assessing the risk and avoiding risks such as damage caused by continuing operation at the limit position.
- step S103 the processor determines whether the shelf should execute the current lifting command based on historical data and the current lifting command, including:
- the processor determines that the shelf will not execute the current lifting command.
- the first extreme position is the upper extreme position
- the second extreme position is the lower extreme position.
- the lifting command is not executed in this case, and the shelf body remains in its current position. Otherwise, it indicates that the shelf body is not in an extreme position or there is no risk of damage, and the lifting command can be executed. After executing the lifting command, if the shelf body reaches its extreme position, control is stopped.
- the processor determines the historical information characterizing the shelf body at its limit position by:
- the processor determines that the historical record information indicates that the shelf body is in the first limit position.
- the processor determines that the historical record information indicates that the shelf body is in the second limit position.
- the trigger part of the target gear including the first protrusion means that there is only one trigger part on the target gear. It is set that when the drive signal is low, the shelf body executes an upward or downward command. When the drive signals corresponding to the upward and downward commands are both high, the shelf body remains stationary. Referring to Figures 4-1 and 4-2 and the preceding description, when the trigger part of the target gear includes the first protrusion, the microswitch is in the conducting state during the lifting and lowering of the shelf body.
- the output signal is the first signal (the first signal is a high-level signal, and the microswitch being on indicates that the shelf body has not reached its limit position); when the shelf body reaches its limit position, the microswitch is in the off state, and the output signal is the second signal, i.e., the second limit signal (the second signal is a low-level signal, and the microswitch being off indicates that the shelf has reached its limit position).
- the shelf body executes the upward command
- the drive signal corresponding to the upward command is a low-level signal
- the output signal of the trigger switch is the first signal (the trigger switch is in the on state). If the shelf body rises to the first extreme position, the output signal of the trigger switch changes from the first signal to the second signal; at the same time, the drive signal also changes from a low-level signal to a high-level signal, that is, the drive mechanism stops operating. Therefore, during the upward process, when the drive signal changes and the output signal of the micro switch changes from the first signal to the second signal, it indicates that the shelf body has reached the first extreme position.
- the corresponding drive signal is a low-level signal
- the trigger switch output signal is the first signal (the trigger switch is in the ON state). If the shelf descends to the second limit position, the trigger switch output signal changes from the first signal to the second signal. Simultaneously, the drive signal changes from low to high, stopping the operation. Therefore, when the drive signal changes during descent and the microswitch output signal changes from the first signal to the second signal, it indicates that the shelf body has reached the second limit position. Thus, based on the changes in the output signal and drive signal corresponding to the trigger unit's structure, it can be determined whether the shelf body is in a limit position and whether it is in the first or second limit position.
- the processor determines the historical output signal of the microswitch to characterize the shelf body being in its extreme position by:
- the processor determines that the historical record information indicates that the shelf body is in the first limit position.
- the processor determines that the historical record information indicates that the shelf body is in the second limit position.
- the trigger part of the target gear includes a groove
- the target gear has only one trigger part.
- the output signals of the corresponding trigger switches during the lifting and lowering process are not the same.
- the shelf body executes the rise or fall command.
- both the rise and fall drive signals are high level, the shelf body remains stationary.
- the output signal is the second signal (the second signal is a low level signal, and the micro switch being off indicates that the shelf body has not reached the limit position); when the shelf body reaches the limit position, the micro switch is in the on state, and the output signal is the first signal, i.e., the first limit signal (the first signal is a high level signal, and the micro switch being on indicates that the shelf has reached the limit position).
- the target gear has two triggering units
- the state of the output signal from the first triggering unit corresponding to the first extreme position is used to determine whether it is at the first extreme position.
- the state of the output signal from the second triggering unit corresponding to the second extreme position is used to determine whether it is at the second extreme position.
- the specific judgment logic is as described above and will not be repeated here.
- the above-mentioned determination of extreme positions can be used for historical output signals or for the current output signal.
- this disclosure provides another method for controlling a shelf, including:
- S101 receives the lifting and lowering command for the shelf.
- the changes in the drive signal and the output signal of the microswitch during the raising and lowering process are recorded and stored.
- the previously stored historical data can be analyzed to determine whether the shelf body is at its limit position. This determines whether the shelf should execute the latest raising and lowering command, thereby preventing damage to the shelf.
- only the relevant signal information is recorded and saved after each control operation; the shelf body position is not determined. The limit position is determined before the next control operation.
- this disclosure provides another method for controlling a shelf, including:
- S101 receives the lifting and lowering command for the shelf.
- S305 controls the shelf body to rise or fall when the shelf receives a lifting command for the first time.
- the shelf receives a lifting command for the first time, since the shelf is usually in an initial position between its upper and lower limits when it leaves the factory, there is no need to determine the position of the shelf body.
- the control command can be executed directly to control the shelf body to rise or fall.
- the changes in the output signal and drive signal of the micro switch can be recorded or saved as in the previous embodiment.
- the position of the shelf body is determined after each control, so that it can be directly called during the next control.
- this embodiment of the disclosure provides a control device 400 for a shelf, including a processor 401 and a memory 402.
- the device 400 may further include a communication interface 403 and a bus 404.
- the processor 401, communication interface 403, and memory 402 can communicate with each other via the bus 404.
- the communication interface 403 can be used for information transmission.
- the processor 401 can call logical instructions in the memory 402 to execute the control device method for the shelf described in the above embodiment.
- the logical instructions in the aforementioned memory 402 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.
- the memory 402 as a computer-readable storage medium, can be used to store software programs and computer-executable programs, such as program instructions/modules corresponding to the methods in the embodiments of this disclosure.

结合图1至3所示,本公开实施例提供一种搁物架,包括搁物架本体200、驱动机构100和限位机构。其中,驱动机构100,包括电机101和齿轮组件,以驱动搁物架本体200移动。齿轮组件包括目标齿轮,在目标齿轮105上设有触发部。限位机构,包括一个微动开关104。微动开关104与目标齿轮105接触,在目标齿轮105转动使微动开关104和触发部151(152)接触时,微动开关104被触发使得微动开关104的输出信号发生跳变输出限位信号。
这里,搁物架本体200在驱动机构的作用下上下移动。驱动机构的齿轮组件包括传动齿轮102和输出齿轮103;传动齿轮102与电机101的输出轴和输出齿轮103连接,输出齿轮103转动带动搁物架本体200移动。电机转动时,传动齿轮102、输出齿轮103依次啮合转动。其中,传动齿轮102和输出齿轮103均可作为目标齿轮105,基于需求选择目标齿轮。作为一种示例,可以将搁物架由一极限位置运动至另一极限位置时刚好转动一圈的齿轮作为目标齿轮。这样,在搁物架上升(可对应电机正转)或下降(可对应电机反转)过程中,仅在达到极限位置时才能触发微动开关,便于根据微动开关输出的触发信号确定搁物架是否达到极限位置。
限位机构的微动开关104设置于目标齿轮105的触发部所在端面的相对侧,以使微动开关104与目标齿轮105的端面接触。目标齿轮的端面是指与齿轮轴线垂直的两个面。其中,微动开关与目标齿轮的端面接触包括微动开关与目标齿轮的端面直接接触,或者,微动开关与目标齿轮的端面间接接触。间接接触是指微动开关和目标齿轮之间存在接触件。可以理解地,微动开关与目标齿轮的端面直接接触时,微动开关安装于目标齿轮的端面相对侧,且与端面上的触发部抵接。微动开关与目标齿轮的端面间接接触时,微动开关安装于目标齿轮端面相对侧,且微动开关和目标齿轮错开设置,二者通过连接件间接接触。在间接接触时,因微动开关和目标齿轮相错,使得微动开关可以安装在目标齿轮的外侧,这样安装更加容易且方便。
目标齿轮105上设有触发部151(152),当目标齿轮转动使触发部和微动开关接触时,微动开关104被触发。作为一种示例,目标齿轮上设有凸起部152,该凸起部作为触发部(即当目标齿轮转动至微动开关和凸起部接触被触发时,表明搁物架本体移动至极限位置)。在目标齿轮凸起部以外的端面和微动开关接触时,微动开关处于导通状态。在目标齿轮转动至凸起部时,凸起部触发微动开关使微动开关由导通状态变为断开状态。这样,可以基于微动开关的输出信号判断搁物架是否升降至极限位置。此外,触发部在目标齿轮上的位置取决于极限位置和目标齿轮的大小。
采用本公开实施例提供的搁物架,将驱动机构的一个齿轮作为目标齿轮,并在目标齿轮上设置触发部。设置一个与目标齿轮接触的微动开关,在目标齿轮转动使微动开关被触发部触发,微动开关输出限位信号。通过限位信号判断搁物架本体的位置。这样,通过一个微动开关可实现搁物架本体极限位置的检测,降低了成本且减少了搁物架电动组件的体积。
可选地,目标齿轮105转动一圈产生的升降行程大于或等于搁物架本体从第一极限位置至第二极限位置的行程。
这里,将转动一圈时搁物架本体理论升降行程大于或等于搁物架本体最大行程的齿轮作为目标齿轮。其中,搁物架本体理论升降行程是指不考虑极限位置的限制,搁物架本体随着目标齿轮的转动从当前位置上升/下降至目标齿轮转动一圈达到位置的行程。搁物架本体最大行程是指搁物架本体从一个极限位置上升或下降至另一极限位置的行程(即第一极限位置至第二极限位置的行程,或者,第二极限位置至第一极限位置的行程)。可以理解地,在目标齿轮转动一圈对应的升降行程等于最大行程时,目标齿轮上设置一个触发位置即可。在目标齿轮转动一圈对应的升降行程大于最大行程时,目标齿轮上设置两个触发位置,一个对应上极限位置、一个对应下极限位置。这是因为,上升或下降时目标齿轮的转动方向相反,目标齿轮需要在两个极限位置对应的触发部之间进行反复运动,目标齿轮转动一圈的行程大于两个极限位置的行程,故需在目标齿轮上设置两个触发部。如此,仅在达到极限位置时触发微动开关。
可选地,触发部包括设置于目标齿轮105端面上第一凸起152和/或凹槽151,在微动开关104被触发时,第一凸起152或凹槽151与微动开关接触。
这里,在目标齿轮的触发部仅有一个的情况下,触发部可以是第一凸起或凹槽。作为一种示例,触发部为凹槽,在目标齿轮未转动到凹槽位置时,微动开关的输出信号保持初始状态(如微动开关保持断开状态)。在目标齿轮转动使微动开关因凹槽让位弹起时,微动开关的状态由断开状态变为导通状态,同时输出信号发生跳变输出限位信号。在目标齿轮的触发部有两个的情况下,两个触发部分别对应上极限位置和下极限位置。且两个触发部可以均为第一凸起,或者均为凹槽,或者一个触发部为凹槽另一触发部为第一凸起。如此,基于微动开关的输出信号和搁物架本体的升降状态,可进一步检测搁物架本体是否达到极限位置。
结合图4、5所示,可选地,微动开关和目标齿轮通过连接件接触,连接件包括支撑杆111和活动杆112。支撑杆111固定安装。活动杆112与支撑杆111活动连接,活动杆112的第一端的上端面设有第二凸起114,第二凸起与目标齿轮105接触;第一端的下端面连接弹性组件113;活动杆112的第二端与微动开关104接触。其中,在目标齿轮105转动到触发部时,活动杆112的第二凸起与触发部151/152接触,使活动杆的第二端下压以触发微动开关或在弹性组件的作用下使活动杆的第二端抬起以触发微动开关。
这里,为了方便微动开关的安装设置,设置连接件以使微动开关和目标齿轮通过连接件间接接触。具体地,连接件包括支撑杆、活动杆以及弹性组件。支撑杆固定安装,活动杆活动安装于支撑杆上。活动杆的第二端与微动开关接触,第一端与弹性组件的一端连接、且第一端与目标齿轮接触的端面上设有第二凸起;弹性组件的另一端固定。结合图4-1和图4-2,在触发部为第一凸起152时,活动杆112的第二凸起114在与目标齿轮105的非触发部接触时,目标齿轮105不对活动杆112的第二凸起114施加向下的作用力,故活动杆112在弹性组件113的作用下下压微动开关(此时弹性组件处于拉伸状态或正常状态),使微动开关104保持导通状态。在目标齿轮105转动使第一凸起152和活动杆112的第二凸起114接触时,第一凸起152对活动杆112的第一端(即第二凸起所在端)产生下压作用力,弹性组件113被压缩。此时活动杆112的第二端抬起,与微动开关104断开接触,故微动开关104可由导通状态变为断开状态,输出信号发生跳变输出限位信号。作为一种示例,弹性组件为支撑弹簧。
结合图5-1和图5-2,在触发部为凹槽151时,活动杆112的第二凸起114在与目标齿轮105的非触发部接触时,目标齿轮对活动杆112的第二凸起施加向下的作用力,弹性组件113此时处于压缩状态,故活动杆112的第二端抬起、与微动开关104不接触。此时,微动开关104处于断开状态。在目标齿轮105转动使凹槽151和活动杆112的第二凸起114接触时,活动杆112的第一端在弹性组件113的作用下抬起,同时活动杆的第二端下压触发微动开关104,使微动开关104由断开状态变为导通状态,输出信号发生跳变。如此,微动开关的输出信号会随着目标齿轮的转动发生变化,从而用于判断搁物架本体是否升降至极限位置。
结合图6所示,本公开实施例提供一种搁物架的控制方法,包括:
S101,接收搁物架的升降指令。
S102,在搁物架非首次接收升降指令的情况下,获取上一次升降时的历史记录信息。
S103,根据历史记录信息和本次升降指令,确定搁物架是否执行本次升降指令。
S104,在确定执行本次升降指令的情况下,控制搁物架本体上升或下降。
这里,在接收搁物架的升降指令时,先判断是否为首次控制指令。如果为首次接收升降指令,则控制搁物架本体执行本次升降指令。这是因为搁物架出厂时处于初始状态,首次执行升降指令,不存在搁物架本体处于极限位置的情况。如果为非首次接收升降指令,则搁物架在上次升降后可能会处于极限位置。本次升降指令可能会使得搁物架继续移动突破极限位置,造成损坏。因此,在这种情况下获取上一次升降的历史记录信息。其中,历史记录信息包括搁物架本体的位置信息。在一些实施例中,历史记录信息包括微动开关的输出信号和驱动信号(驱动信号对应上升或下降指令)。这样可以通过输出信号和驱动信号判断搁物架本体是否处于极限位置。如果处于极限位置,则搁物架可能不执行本次升降指令。在另一些实施例中,历史记录信息包括搁物架的升降位置信息,即包括记录搁物架上升/下降至对应的极限位置。
进而基于历史记录信息和本次升降指令,确定是否执行本次升降指令。可以理解地,搁物架本体的极限位置包括上极限位置和下极限位置。在历史记录信息表征搁物架本体处于上极限位置时,如果本次升降指令为上升指令,则执行本次升降指令会造成搁物架损坏风险,故这种情况下不执行本次升降指令。但如果本次升降指令为下降指令,则确定执行本次升降指令。同样地,在历史记录信息表征搁物架本体处于下极限位置时,如果本次升降指令为下降指令,则确定不行本次升降指令。但如果本次升降指令为上升指令,则确定执行本次升降指令。此外,在历史记录信息表征搁物架本体不处于极限位置时,则确定执行本次升降指令。最后,在确定执行本次升降指令时,控制搁物架本体执行指令。如此,在搁物架本体执行升降指令前,先确定是否存在损坏风险,如果存在损坏风险,则不执行相应指令。如果不存在损坏风险,则执行损坏风险。
采用本公开实施例提供的用于搁物架的控制方法,在搁物架非首次执行升降指令时,获取上一次升降的历史记录信息。根据历史记录信息和本次升降指令,确定是否存在损坏风险。如果不存在,则控制搁物架本体升降。这样,基于历史记录信息判断是否处于极限位置,进而判断风险情况。从而避免在极限位置时继续动作而引发损坏等风险。
可选地,步骤S103,处理器根据历史记录信息和本次升降指令,确定搁物架是否执行本次升降指令,包括:
在历史记录信息表征搁物架本体处于第一极限位置、且本次升降指令为上升指令的情况下,或者,在历史记录信息表征搁物架本体处于第二极限位置、且本次升降指令为下降指令的情况下,处理器确定搁物架不执行本次升降指令。
这里,第一极限位置为上极限位置,第二极限位置为下极限位置。在搁物架本体处于第一极限位置且本次升降指令为上升指令时,或者,在搁物架本体处于第二极限位置且本次升降指令为下降指令时,搁物架执行本次指令存在损坏风险,故此时不执行升降指令,即搁物架本体保持当前位置。在以上情形之外时,则表明搁物架本体不处于极限位置或者不存在损坏风险,则可以执行本次升降指令。在执行本次升降指令后,如果搁物架本体达到极限位置,则停止控制。
结合图7所示,可选地,在目标齿轮的触发部包括第一凸起的情况下,处理器通过以下方式确定历史记录信息表征搁物架本体处于极限位置:
在历史升降指令为上升指令且对应的驱动信号跳变、且微动开关输出第二限位信号的情况下,处理器确定历史记录信息表征搁物架本体处于第一极限位置。
在历史升降指令为下降指令且对应的驱动信号跳变、且微动开关输出第二限位信号的情况下,处理器确定历史记录信息表征搁物架本体处于第二极限位置。
这里,目标齿轮的触发部包括第一凸起是指目标齿轮上仅设有一个触发部。且设定在驱动信号为低电平时,搁物架本体执行上升或下降指令。在上升和下降指令对应的驱动信号均为高电平时,则搁物架本体保持不动。结合图4-1和4-2以及前文所述,在目标齿轮的触发部包括第一凸起时,微动开关在搁物架本体升降过程中处于导通状态,此时输出信号为第一信号(第一信号为高电平信号,且微动开关导通表征搁物架本体未达到极限位置);微动开关在搁物架本体达到极限位置时,处于断开状态输出信号为第二信号即第二限位信号(第二信号为低电平信号,且微动开关断开表征搁物架达到极限位置)。
进一步地,根据驱动信号和微动开关的输出信号,判断搁物架是否处于极限位置,且处于第一极限位置还是第二极限位置。具体地,在搁物架本体执行上升指令时,上升指令对应的驱动信号为低电平信号,触发开关的输出信号为第一信号(触发开关状态为导通状态)。如果搁物架本体上升至第一极限位置,则触发开关的输出信号由第一信号跳变为第二信号;同时,驱动信号也由低电平信号跳变为高电平信号即驱动机构停止动作。因此,在上升过程中,驱动信号跳变且微动开关的输出信号由第一信号跳变为第二信号时,表征搁物架本体达到第一极限位置。
同样地,在搁物架本体执行下降指令时,下降指令对应的驱动信号为低电平信号,触发开关输出信号为第一信号(触发开关状态为导通状态)。如果搁物架下降至第二极限位置,则触发开关的输出信号由第一信号跳变为第二信号。同时,驱动信号也由低电平跳变为高电平信号即停止动作。故在下降过程中驱动信号跳变且微动开关的输出信号由第一信号跳变为第二信号时,表征搁物架本体达到第二极限位置。这样,基于触发部的结构对应的输出信号和驱动信号的变化情况,可以确定搁物架本体是否处于极限位置以及处于第一极限位置还是第二极限位置。
结合图8所示,可选地,在目标齿轮的触发部包括凹槽的情况下,处理器通过以下方式确定微动开关的历史输出信号表征搁物架本体处于极限位置:
在历史升降指令为上升指令且对应的驱动信号跳变、且微动开关输出第一限位信号的情况下,处理器确定历史记录信息表征搁物架本体处于第一极限位置。
在历史升降指令为下降指令且对应的驱动信号跳变、且微动开关输出第一限位信号的情况下,处理器确定历史记录信息表征搁物架本体处于第二极限位置。
这里,目标齿轮的触发部包括凹槽是指目标齿轮上仅设有一个触发部。如前文所述,因触发部的结构不同时,对应的触发开关的在升降过程中的输出信号并不相同。同样地,设定在上升/下降驱动信号为低电平时,搁物架本体执行上升或下降指令。在上升和下降的驱动信号均为高电平时,则搁物架本体保持不动。结合图5-1和5-2以及前文所述,在目标齿轮的触发部包括凹槽时,微动开关在搁物架本体升降过程中处于断开状态,此时输出信号为第二信号(第二信号为低电平信号,且微动开关断开表征搁物架本体未达到极限位置);微动开关在搁物架本体达到极限位置时处于导通状态,此时输出信号为第一信号即第一限位信号(第一信号为高电平信号,且微动开关导通表征搁物架达到极限位置)。
因此,在上升过程中,驱动信号跳变、微动开关的历史输出信号由第二信号跳变为第一信号,则确定搁物架本体处于第一极限位置。在下降过程中,驱动信号跳变、微动开关的历史输出信号由第二信号跳变为第一信号,则确定搁物架本体处于第二极限位置。
此外,在目标齿轮的触发部为两个的情况下,则在上升时,基于第一极限位置对应的第一触发部输出信号的状态,判断是否处于第一极限位置。在下降时,基于第二极限位置对应的第二触发部输出信号的状态,判断是否处于第二极限位置。具体判断逻辑如前文所述,在此不再赘述。上述极限位置的判断可以用于历史输出信号,也可以用于当前输出信号。
结合图9所示,本公开实施例提供另一种搁物架的控制方法,包括:
S101,接收搁物架的升降指令。
S102,在搁物架非首次接收升降指令的情况下,获取上一次升降时的历史记录信息。
S103,根据历史记录信息和本次升降指令,确定搁物架是否执行本次升降指令。
S104,在确定执行本次升降指令的情况下,控制搁物架本体上升或下降。
S205,在搁物架本体停止升降的情况下,记录并存储搁物架本体本次升降时微动开关的输出信号和驱动信号。
这里,在每次搁物架本体升降时,均将在升降过程中的驱动信号和微动开关的输出信号的变化情况进行记录和存储。如此,在下一次进行升降控制时,可以基于前一次存储的历史记录信息进行分析判断,确定搁物架本体是否处于极限位置。进而确定搁物架是否执行最新的升降指令,从而避免搁物架损坏。本公开实施例中,在每次控制结束后,仅记录保存相关信号的信息,不进行搁物架本体位置的确定。在下一次控制前进行极限位置的判定。
结合图10所示,本公开实施例提供另一种搁物架的控制方法,包括:
S101,接收搁物架的升降指令。
S102,在搁物架非首次接收升降指令的情况下,获取上一次升降时的历史记录信息。
S103,根据历史记录信息和本次升降指令,确定搁物架是否执行本次升降指令。
S104,在确定执行本次升降指令的情况下,控制搁物架本体上升或下降。
S305,在搁物架首次接收升降指令的情况下,控制搁物架本体上升或下降;
S306,在搁物架本体停止升降的情况下,根据微动开关的输出信号,判断搁物架本体是否处于极限位置;
S307,记录并保存判断结果。
这里,在搁物架首次接收升降指令时,因搁物架通常出厂时处于上下极限位置之间的初始位置,故无需判断搁物架本体的位置。可直接执行控制指令,控制搁物架本体上升或下降。但在首次控制结束后,可以如前一实施例记录或保存微动开关的输出信号和驱动信号的变化情况。也可以在控制结束后,判断本次升降后搁物架本体是否处于极限位置。即判断是否处于第一极限位置或第二极限位置,并保存记录结果。这样,在下一次升降控制时,可以直接调用前一次控制后搁物架本体的位置信息。如此,在每次控制结束后均进行搁物架本体位置的确定,从而在下一次控制时直接调用。
结合图11所示,本公开实施例提供一种搁物架的控制装置400,包括处理器(processor)401和存储器(memory)402。可选地,该装置400还可以包括通信接口(Communication Interface)403和总线404。其中,处理器401、通信接口403、存储器402可以通过总线404完成相互间的通信。通信接口403可以用于信息传输。处理器401可以调用存储器402中的逻辑指令,以执行上述实施例的用于搁物架的控制装置方法。
此外,上述的存储器402中的逻辑指令可以通过软件功能单元的形式实现并作为独立的产品销售或使用时,可以存储在一个计算机可读取存储介质中。

存储器402可包括存储程序区和存储数据区,其中,存储程序区可存储操作系统、至少一个功能所需的应用程序;存储数据区可存储根据终端设备的使用所创建的数据等。此外,存储器402可以包括高速随机存取存储器,还可以包括非易失性存储器。
