Description

一种自适应满行程检测电磁感应式电位器
技术领域
本发明涉及电子技术领域，具体涉及一种自适应满行程输出电磁感应式电位器。
背景技术
电位器是可变电阻器的一种，通常是由电阻体与转动或滑动系统组成，即靠一个动触点在电阻体上移动，获得部分电压输出。传统电位器大多使用碳膜或者电阻丝结构，需要触点接触到碳膜上摩擦，来实现电位器不同位置检测。传统电位器的接触式结构，存在以下方面的不足：(1)碳膜磨损寿命短，生产误差大；(2)由于结触点的摩擦，位置变动时会有接触干扰杂波产生，如果作为音箱等调整音量使用，在调整时，就会有滋啦滋啦的干扰声。
电磁感应式电位器克服了上述不足，使用永磁体作为转动或者滑动部分组件，并使用线性霍尔传感器实时检测永磁体位置。电磁感应式电位器在调整位置时，无接触，无磨损，没有调整时的杂波干扰。申请号为CN201320158412.9的中国专利、申请号为CN201721701957.4的中国专利均公开了电磁感应式电位器方案。
然而，由于永磁体在产生中磁性一致性较差，应用于电磁感应式电位器时则存在输出范围不一致的问题，若对电磁感应式电位器的输出进行逐一校准，则需要耗费额外的时间、人力和设备成本，不便于大批量生产。针对这个问题，目前采用解决方式为：设定一个相对较小、安全的固定值范围对霍尔传感器的输出值进行检测。如图1所示，对应于同样的电位器行程，霍尔传感器的输出范围存在个体差异，在检测时采用一个相对保守的检测范围，并根据输出特性以该检测范围来限定电位器输出范围，超出检测范围的行程位置则直接输出最大值或最小值。这种方式又带来了一个新的问题，即电位器的输出范围仅能对应电位器的部分行程，当传感器输出不在检测范围内时，该处行程位置难以有效检测，无法实现满行程检测，影响了使用体验。
因此，如何克服电磁感应式电位器中永磁体磁性不一致性导致的输出范围差异，并实现电磁感应式电位器满行程检测成为亟待解决的技术问题。

可选地，所述实际电位采样范围的最大值减去所述实际电位采样范围的最小值之差作为实际电位采样范围幅度，所述实际电位输出范围的最大值减去所述实际电位输出范围的最小值之差作为实际电位输出范围幅度，所述实际电位采样值与所述实际电位采样范围幅度的比值等于所述实际电位输出值与所述实际电位输出范围幅度的比值。
可选地，操作步骤S4具体为：
将所述初始电位采样值分别与实际电位采样范围的最大值和最小值进行比较，若所述初始电位采样值处于所述实际电位采样范围之内，则不对所述实际电位采样范围进行调整；若所述初始电位采样值小于所述实际电位采样范围的最小值，则以所述初始电位采样值来更新所述实际电位采样范围的最小值；若所述初始电位采样值大于所述实际电位采样范围的最大值，则以所述初始电位采样值来更新所述实际电位采样范围的最大值。
可选地，所述活动部为转动件，用于获取转动角度位置变化输入。

具体实施方式
为了更加清楚、完整的说明本发明的技术方案，下面结合附图对本发明作进一步说明。
实施例一
请参见图1，本发明提出一种自适应满行程检测电磁感应式电位器100，包括：转动件101、永磁体102、磁感应传感器103和自适应满行程输出调节单元104。转动件101受到外力时绕中心转动，转动件101用于接收外部转动输入，电位器的输出可反映所输入的转动角度位置变化。永磁体102附着于转动件101，可跟随转动件101转动。磁感应传感器103用于感应永磁体102的位置，并产生初始电位信号。自适应满行程输出调节单元104用于采集初始电位信号，并自适应地将初始电位信号调整为对应于转动件101完整位置变化行程的实际电位信号。
本发明实施例提出的一种自适应满行程检测电磁感应式电位器100，可以克服传统电位器因接触点存在摩擦而导致的寿命短、干扰大的不足，通过自适应满行程输出调节单元的设置，能够实现电位器满行程位置检测。
进一步地，作为一种优选实施例，自适应满行程输出调节单元104包括：信息采集模块、信号输出模块和控制模块。信息采集模块用于采集初始电位信号，获得初始电位采样值。信号输出模块用于输出实际电位信号。
控制模块，用于执行如下操作步骤：
S1：读取预设电位采样范围，将预设电位采样范围的最小值作为实际电位采样范围的最小值，将预设电位采样范围的最大值作为实际电位采样范围的最大值；
S2：控制信息采集模块对磁感应传感器的输出进行采样，获取初始电位采样值；
S3：根据初始电位采样值与实际电位采样范围的比较结果，得出实际电位输出值，并控制信号输出模块输出实际电位信号；
S4：根据初始电位采样值与实际电位采样范围的比较结果，调整实际电位采样范围；
S5：返回执行步骤S2。
需要说明的是，在本实施例中，预设采样范围可存储于非易失性存储设备中，即在掉电情况下还能保持数据。预设采样范围是一个相对安全的参数范围，能够适应磁感应传感器103因个体差异所产生的输出范围差异。作为一种示例，预设采样范围的边界可设置于多个磁感应传感器103输出值的边界以内。
本发明实施例通过自适应满行程输出调节单元104设置预设采样范围，根据初始电位采样值与实际电位采样范围的比较结果来得出实际电位输出值，以及在得出实际电位输出值后根据初始电位采样值与实际电位采样范围的比较结果来调整实际电位采样范围，可以实现对磁感应传感器103采样范围的动态调整，在初始电位采样值超过预设电位采样范围时，能够自适应、动态地更新采样范围，确保磁感应传感器103输出范围内的数值均能被采集到，即保证电位器在整个行程范围内的任一位置都能被检测到。
在可选的实施例中，操作步骤S3具体为：
将初始电位采样值分别与实际电位采样范围的最大值和最小值进行比较，若初始电位采样值处于实际电位采样范围之内，则以初始电位采样值作为实际电位采样值；若初始电位采样值小于实际电位采样范围的最小值，则以实际电位采样范围的最小值作为实际电位采样值；若初始电位采样值大于实际电位采样范围的最大值，则以实际电位采样范围的最大值作为实际电位采样值；通过实际电位采样值、实际电位采样范围和实际电位输出范围确定实际电位输出值，控制信号输出模块根据实际电位输出值来输出实际电位信号。
在可选的实施例中，实际电位采样范围的最大值减去实际电位采样范围的最小值之差作为实际电位采样范围幅度，实际电位输出范围的最大值减去实际电位输出范围的最小值之差作为实际电位输出范围幅度，实际电位采样值与实际电位采样范围幅度的比值等于实际电位输出值与实际电位输出范围幅度的比值。通过上述约束关系，可以根据实际电位采样值、实际电位采样范围和实际电位输出范围来计算出实际电位输出值。
在可选的实施例中，操作步骤S4具体为：
将初始电位采样值分别与实际电位采样范围的最大值和最小值进行比较，若初始电位采样值处于实际电位采样范围之内，则不对实际电位采样范围进行调整；若初始电位采样值小于实际电位采样范围的最小值，则以初始电位采样值来更新实际电位采样范围的最小值；若初始电位采样值大于实际电位采样范围的最大值，则以初始电位采样值来更新实际电位采样范围的最大值。
以下通过一个示例说明本实施例的调整效果。以应用于游戏手柄摇杆的磁感应电位器采样为例，默认设置磁感应传感器的预设电位采样范围为0.7V-2.5V，当使用时发现磁感应传感器的初始电位采样值的范围到了0.5V-3V，会动态地把实际电位采样范围调整到0.5V-3V，直到断电，在重新上电后，恢复到默认范围0.7V-2.5V；若使用时磁感应传感器的初始电位采样值的范围为0.8V-2.4V时，则仍然使用默认的预设电位采样范围0.7V-2.5V；若使用时磁感应传感器的初始电位采样值的范围为0.8V-2.8V时，则会动态把实际电位采样范围调整到0.7-2.8V；若使用时磁感应传感器的初始电位采样值采样电压范围为0.5V-2.4V时，则会动态把实际电位采样范围调整到0.5V-2.5V。
本发明实施例通过预设采样范围、参数对比、使用当前值输出，以及自适应调整采样范围的步骤，在采样值超过预设范围值时，仍然能够实时自适应地更新预设采样范围，即电位器可根据实际使用情况动态地、自适应地修正输出特性，从而确保能够对满量程范围内的位置进行检测，提升了用户的使用体验，该设置方式无需对每一电位器进行单独校准，提高了生产效率。
在可选的实施例中，实际电位信号为模拟信号或数字信号。自适应满行程输出调节单元中的信号输出模块可将实际电位信号调整为模拟信号或数字信号进行输出。
在可选的实施例中，磁感应传感器103为霍尔传感器。
实施例二
参见图3、图4，本发明提出一种自适应满行程检测电磁感应式电位器200，包括外壳201、转动件202、永磁体203、磁感应传感器和自适应满行程输出调节单元。转动件202相对于外壳201转动，转动件202扣接于外壳201，永磁体203嵌设于转动件202。磁感应传感器和自适应满行程输出调节单元可另设于外壳201以外的外部电路中，自适应满行程输出调节单元可以为单元机、微处理器或DSP。磁感应传感器用于感应永磁体203的位置，并产生初始电位信号。自适应满行程输出调节单元用于采集初始电位信号，并自适应地将初始电位信号调整为对应于转动件202完整位置变化行程的实际电位信号。
本实施例中，自适应满行程输出调节单元的内部设置与实施例一的自适应满行程输出调节单元104相同，此处不再赘述。
实施例三
