图1仅为控制器101中的一组测量电压采集电路104和测量电压采集端子105与一个马达驱动电路102连接的结构示意图，图1所示的结构示意图用于确定控制系统100上的一个孔中是否安装有立柱，以及在该孔中安装立柱的情况下，确定该立柱的类型。
图2为本申请实施例提供的一种电动升降桌的控制系统的电路连接示意图，如图2所示，可选的，测量电压采集电路104包括第一电阻R1，第一电阻R1的第一端与电源电压端VCC电连接，第一电阻R1的第二端与测量电压采集端子105和微处理器103均电连接。
可选的，控制器101还包括第一接地端子11，马达驱动电路102还包括第二接地端子12，第二接地端子12连接第一接地端子11；测量电压产生电路106包括第二电阻R2，第二电阻R2的第一端与第二接地端子电连接，第二电阻R2的第二端与测量电压输出端子107电连接；
第二电阻R2的阻值与立柱数量和立柱类型均对应。
可选的，第一电阻R1的阻值与第二电阻R2的阻值相同或不同。
继续参考图2，第一电阻R1的阻值为固定值，例如第一电阻R1的阻值可以为10K、20K等，在测量过程中将第一电阻R1的阻值设置为固定值，可以方便微处理器103执行其功能，保证测量结果的准确性。第二电阻R2的第一端与第二接地端子12电连接，第二电阻R2的第二端与测量电压输出端子107电连接。控制器101还包括第一接地端子11，第一接地端子11与第二接地端子12电连接，且第一接地端子11与第二接地端子12均与接地端GND连接。第二电阻R2可根据不同立柱类型进行对应设置，不同立柱类型对应的第二电阻R2的阻值不同，保证微处理器102判断结果的准确性。第一电阻R1的阻值与第二电阻R2的阻值可以相同或不同，均能保证测量结果的准确。
可选的，微处理器103设置为比较测量电压采集电路104提供的电压信号与电源电压信号，并在测量电压采集电路104提供的电压信号等于电源电压信号时，判定控制器101与马达驱动电路102断开；在测量电压采集电路104提供的电压信号小于电源电压信号时，判定控制器101与马达驱动电路102连接。
与图1类似的，图2也仅示出了控制器101中的一组测量电压采集电路104和测量电压采集端子105与一个马达驱动电路102连接的电路连接示意图。第二电阻R2的阻值即为马达驱动电路102中的等效阻值。第二电阻R2的阻值与立柱数量和立柱类型均对应，是指根据第二电阻R2的阻值可以确定马达驱动电路102所在的立柱是否安装于孔中，以及在马达驱动电路102所在的立柱安装于孔中的情况下，根据第二电阻R2的阻值可以确定该立柱的类型。本实施例中，第二电阻R2的阻值因立柱是否安装，以及安装的立柱类型改变。
控制器101与马达驱动电路102断开，实际是指控制器101对应的孔中未安装立柱，相当于第二电阻R2对应的阻值无限大。控制器101与马达驱动电路102连接实际是指控制器101对应的孔中安装立柱，即在图2中，第二电阻R2对应的阻值与立柱类型对应。
图3为本申请实施例提供的一种电动升降桌的控制系统的等效电路图。测量电压产生电路106由第二电阻R2决定，由于测量电压采集端子105与测量电压输出端子107电连接，测量电压输出端子107输出对应第二电阻R2的电压信号，测量电压采集端子105接收测量电压输出端子107输出的对应第二电阻R2的电压信号，微处理器103接收对应第二电阻R2的电压信号和第一电阻R1的电压信号，如图3所示，第一电阻R1与第二电阻R2并联。当控制器101与马达驱动电路102断开连接，第二电阻R2对应的电压信号无限大，此时微处理器103接收到的电压信号等于电源电压，即此时马达驱动电路102的测量电压输出端子107并未与立柱连接。当控制器101与马达驱动电路102连接，第一电阻 R1与第二电阻R2并联存在分压作用，此时微处理器102接收到的电压信号小于电源电压，即此时马达驱动电路102的测量电压输出端子107连接立柱。
可选的，立柱数量大于或等于零；立柱类型包括二节立柱、三节立柱的至少一种。
控制系统100的立柱数量可以根据实际需求设计，可以为单立柱、两个立柱、三个立柱、四个立柱等等。判断马达驱动电路102的测量电压输出端子107连接的立柱数量可以为零个。立柱类型可以包括二节立柱、三节立柱，例如可以设置二节立柱对应第二电阻R2的阻值为10K，第三立柱对应第二电阻R2的阻值为20K。对应立柱的数量可以根据需要进行立柱类型的组合。
可选的，电源电压VCC为3.3V、5V或12V。
电源电压VCC的电压值一般与控制器101内微处理器103的电源电压相同，减少设置外部电源的种类，降低成本。
微处理器103还设置为在测量电压采集电路104提供的电压信号小于电源电压信号时，根据电压信号V的计算公式V＝VCC*R2/(R1+R2)以及已知的第一电阻R1的阻值，确定第二电阻R1的阻值，再根据第二电阻R1的阻值与立柱数量和/或立柱类型的对应关系，确定电动升降桌的立柱数量和/或立柱类型。
继续参考图2和图3，不同类型立柱对应不同的第二电阻R2的阻值，因此微处理器103可以根据接收到的不同电压信号进行分析，结合在微处理器103中提前预设的不同立柱类型对应的电压信号值，确定立柱的类型。当第一电阻R1的阻值为10K，二节立柱对应的第二电阻R2的阻值为10K，三节立柱对应的第二电阻R2的阻值为20K，电源电压VCC为5V，微处理器103中预设当第二电阻R2的阻值为10K时，对应测量电压采集电路104提供的电压信号值为2.5V，当第二电阻R2的阻值为20K时，对应测量电压采集电路104提供的电压信号值为3.33V。当微处理器103接收到测量电压采集电路104提供的电压信号V＝5*20/(10+20)＝3.33V时，即可判断出此时马达驱动电路102的测量信号输出端子107电连接有立柱，立柱类型为三节立柱。
可选的，控制器101还包括正转电压端M+、反转电压端M-、霍尔信号端HALL以及霍尔信号供电端VCC_HALL；正转电压端M+设置为传递控制马达驱动电路102电连接的马达的正向转动信号；反转电压端M-设置为传递控制马达驱动电路102电连接的马达的反向转动信号；霍尔信号端HALL设置为传递马达的转子位置信号；霍尔信号供电端VCC_HALL设置为连接为马达内部的霍尔传感器供电的外部设备。
继续参考图2，与控制器101对应，马达驱动电路102也设置有正转电压端 M+、反转电压端M-、第一霍尔信号端HALL1、第二霍尔信号端HALL2以及霍尔信号供电端VCC_HALL，且同类型的端口一一对应，保证多个信号的正确有序传递，有利于控制器101输出控制信号控制马达驱动电路102的工作，进而调节立柱升降。
