  2. 根据权利要求1所述的基于瓶子设置的吸试剂方法，其特征在于，余量探测步骤之前实行主测试步骤，
    主测试步骤包括：
    S1，设定试剂或磁珠在主测试中每次固定的取液量V2；
    S2，控制取样针下降到试剂瓶内液量X-V2的位置，探测得到电压信号数值AD2，将AD2与AD0的差值进行比较，如AD2与AD0的差值超出阈值，则判断为液量正常，测试正常进行，时序动作上，柱塞泵正常吸取试剂；如AD2与AD0的差值未超出阈值，则该测试放弃，后续测试继续；如果连续两次出现AD2与AD0的差值未超出阈值的情况，则测试暂停，提示液面信号异常；
    正常测试全部完成后，对放弃的测试进行试剂瓶内试剂余量探测步骤。
  3. 根据权利要求1所述的基于瓶子设置的吸试剂方法，其特征在于，建立探测器脉冲数值与瓶内液量的关系函数步骤为：
    取液量已知且不同的试剂瓶若干个，将取样针实行液面探测步骤，测得取样针探测到各个液面时的电压信号数值；将试剂瓶内液量与对应测得的电压信号数值按照最小二乘法拟合直线方程，建立电压信号数值与瓶内液量的关系函数。
  4. 根据权利要求2所述的基于瓶子设置的吸试剂方法，其特征在于，主测试步骤之前，还实施扫码识别步骤：将同一类型的试剂瓶在瓶身上设置特定的识别码，吸试剂设备上设置扫码机构对识别码进行扫码以识别试剂瓶的种类。
  5. 根据权利要求2或4所述的基于瓶子设置的吸试剂方法，其特征在于，S2中，建立一个标志位，标志位的初始值为0，当出现AD2与AD0的差值未超出阈值时，标志位的数值加1，当标志位数值达到2，则测试暂停，提示液面信号异常。
  6. 根据权利要求1-4任一项所述的基于瓶子设置的吸试剂方法，其特征在于，三次取值步骤中，在柱塞泵吸试剂或磁珠过程中，串联在管路中的压力传感器监控吸样过程中的压力信号，当压力曲线符合正常吸样的判定算法， 则测试正常进行，时序动作上继续后续吐液到反应杯的动作；若触发空吸条件，则不会去吐液，对应的测试放弃，后续测试继续进行，若连续两次触发空吸，则测试暂停。
  7. 根据权利要求6所述的基于瓶子设置的吸试剂方法，其特征在于，三次取值步骤中，建立一个标志位，标志位的初始值为0，当触发空吸条件时，标志位的数值加1，当标志位数值达到2，则测试暂停。
