结合图1所示，本公开实施例提供一种用于二氧化碳培养箱功率分配的方法，包括：

S02，在当前温度小于或等于目标温度的情况下，二氧化碳培养箱根据功率索引，查表确定各内表面的加热策略。
S03，二氧化碳培养箱按照各内表面的加热策略，调节各内表面的加热丝的功率和/或启停时间。
采用本公开实施例提供的用于二氧化碳培养箱功率分配的方法，根据当前温度和目标温度得到功率索引，接着通过功率索引得到二氧化碳培养箱的各内表面的加热策略，并按该策略调节各内表面的加热丝的功率和/或启停时间，从而实现对二氧化碳培养箱各内表面的加热丝的分别控制，防止二氧化碳培养箱出现凝露。本实施例只需要通过一套算法即可得到一个功率索引，通过该功率索引查表就可得到二氧化碳培养箱各内表面的加热丝的加热策略。不需要通过多套控制算法分别计算实现对加热丝的控制，减少了算法的冗余，提高了控制效率，节省了系统资源。
可选地，二氧化碳培养箱据二氧化碳培养箱箱体的当前温度和目标温度确定功率索引包括：二氧化碳培养箱获取当前温度；二氧化碳培养箱将当前温度与目标温度输入比例-积分-微分PID算法，输出功率索引。
这样，采用PID算法，根据二氧化碳培养箱内部的当前温度与目标温度作为PID算法的输入值，可以得到功率索引。通过一套PID算法计算出功率索引，相比于现有技术通过多套PID算法分别计算二氧化碳培养箱各内表面的加热功率的方案，本实施例减少了多套PID算法导致的控制冗余，节省了系统资源，提高了控制效率。
可选地，二氧化碳培养箱根据功率索引，查表确定二氧化碳培养箱的各内表面的加热策略包括：二氧化碳培养箱根据预先设置好的功率表，确定与功率索引对应的各内表面的加热丝功率；和/或，二氧化碳培养箱根据预先设置好的时间表，确定与功率索引对应的各内表面的加热丝输出时间。
这样，通过预先设置好的功率表，根据功率索引查找功率表上对应的各内表面的加热丝功率，即通过一个功率索引即可获取各内表面上的加热丝的控制策略。或者，通过预先设置好的时间表，通过一个功率索引即可在时间表的对应位置获取各内表面的加热丝的输出时间。或者，通过预选设定好的功率表与时间表，根据一个功率索引即可获取各内表面的加热丝的输出时间与功率。
可选地，二氧化碳培养箱按照各内表面的加热策略，调节各内表面的加热丝的功率和/或启停时间包括：二氧化碳培养箱按照各内表面的加热丝功率，调节各内表面的加热丝的功率至设定功率；和/或，二氧化碳培养箱按照各内表面的加热丝输出时间，控制各内表面的加热丝的启停时间。
其中，控制二氧化碳培养箱各内表面的加热丝的启停时间，可以通过可控硅实现。具体的，可以在二氧化碳培养箱多个内表面设置可控硅，一个可控硅一个内表面的加热丝，根据确定的各内表面加热丝的输出时间对可控硅赋值，以控制加热丝的启停。
这样，根据功率表确定好的各内表面加热丝的功率，控制各内表面的加热丝至设定功率，实现分别控制二氧化碳培养箱各内表面的加热丝的功率，对各内表面的加热丝的功率进行了合理的分配，防止了凝露的产生。或者，根据时间表确定好的各内表面加热丝的输出时间，并控制二氧化碳培养箱各内表面的加热丝的启停时间，通过控制各内表面加热丝的启停，来控制加热丝的在一个加热阶段的输出的时间，从而分配加热丝的功率，实现了对二氧化碳培养箱多个内表面的分别控制，防止了凝露的发生。或者，根据功率表和时间表确定各内表面加热丝的功率和输出时间，控制各内表面加热丝的功率大小和启停时间，实现了对二氧化碳培养箱多个内表面的分别控制，防止了凝露的发生。

S21，在第一设定时长后，二氧化碳培养箱获取箱体的第一当前温度与温度变化速率。

其中，剩余时长为达到目标温度的时间与第一设定时间的时间差值。
采用本公开实施例提供的用于二氧化碳培养箱功率分配的方法，在第一设定时长之后，获取二氧化碳培养箱箱体的第一当前温度与温度变化速率，可以预测经过剩余时长之后，二氧化碳培养箱内部的温度是否达到目标温度。如果未达到目标温度，说明此时二氧化碳培养箱内的各内表面的加热策略不能满足需求，可能产生凝露。因此，根据预测的第二环节温度与目标温度的差值，重新确定加热策略，按照加热策略调节各内表面的加热丝的功率和/或输出时间。避免二氧化碳培养箱在确定加热策略并按照加热策略调节加热丝之后出现的意外情况，导致无法实现在设定时间内达到目标温度，提高了二氧化碳培养箱的适用性。
可选地，二氧化碳培养箱根据第一当前温度和温度变化速率，计算第二当前温度包括：二氧化碳培养箱计算T2＝T1+t×V；其中，T2为第二当前温度，T1为第一当前温度，t为剩余时长，V为温度变化速率。
这样，通过计算剩余时长与温度变化率的乘积，即可获取经过剩余时长，温度的变化值，将该温度的变化值与当前检测到的第一环节温度求和，即可预测经过剩余时长之后的第二当前温度。
可选地，二氧化碳培养箱根据第一当前温度与第二当前温度的差值，调节各内表面的加热丝的功率包括：二氧化碳培养箱根据预设的对应关系，确定与差值相对应的各内表面的加热丝功率；二氧化碳培养箱按照加热丝功率，调节各内表面的加热丝的功率至对应功率。
