具体实施例
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
需要说明的是，本公开中所有获取信号、信息或数据的动作都是在遵照所在地国家相应的数据保护法规政策的前提下，并获得由相应装置所有者给予授权的情况下进行的。
首先对本公开的应用场景进行说明，本公开应用于制氢控制的场景下，在该场景下，如图1所示，图1是本申请根据一示例性实施例示出的一种制 氢控制的系统，包括：氧分离器1、氢分离器2、氧侧差压变送器3、氢侧差压变送器4、控制器5、定位器6、定位器7、调节阀8和调节阀9；其中，氧分离器1和氢分离器2分别用于获取氧气和氢气，并将获取的氧气和氢气分别存储在对应的存储设备；氧侧差压变送器3和氢侧差压变送器4分别用于获取氧分离器1的压强差和氢分离器2的压强差；控制器5用于通过该氧侧差压变送器3和氢侧差压变送器4获取该氧分离器1的压强差和该氢分离器2的压强差，并通过该两个压强差，根据以下公式分别确定氧分离器1和氢分离器2中电解液的液位：
△P＝ρg△h
其中，△P表征压强差，ρ表征电解液的密度，g表征重力加速度，△h表征液位；
根据上述公式分别确定该氧分离器1和该氢分离器2的液位高度，再向该定位器5和定位器6发送控制信号，该定位器5和该定位器6用于接收该控制器5的控制信号，并将该控制信号转换为机械动作，用于控制该调节阀8和调节阀9的阀门。在相关技术中，为了调整氢氧分离器之间的压差，需要通过调节阀的定位器需要指定的输入信号类型，定位器接受不同大小电压信号，根据信号的大小不同，定位器输出调节阀的阀门开度。但是现有的相关技术中，对调节阀的控制需要多种指定的输入信号类型，控制信号复杂，导致可能出现信号偏差的概率较大，且控制信号过于复杂，不利于对氢氧分离器之间差压调节的快速反应。
为了解决上述问题，本申请提供了一种制氢控制的方法、装置、存储介质和控制器，应用于制氢控制系统中的控制器，该制氢控制系统包括控制器，以及与该控制器连接的多个定位器，所述多个定位器与多个调节阀对应连接，用于根据所述控制器的控制信号控制所述调节阀，该调节阀位于该制氢控制系统中的氢氧分离器和储气装置之间的气体输送管道上，用于调节该氢氧分离器之间的压差；该控制器用于控制调节阀的开启或者关闭，该方法包括：获取制氢控制参数，该制氢控制参数包括制氢电流和最近时刻开启的调节阀的开度，该制氢电流为电解水的工作电流；根据该制氢控制参数控制该多个调节阀开启或者关闭，以调节该制氢控制系统中氢氧分离器的压差。这样， 通过制氢参数控制调节阀的开启或者关闭，有利于优化控制信号，减小氢氧分离器之间的压差，保障生产安全，提高制氢系统的工作效率。
下面结合具体地实施例对本申请进行说明。
图2是本申请根据一示例性实施例示出的一种制氢控制的方法，如图2所示，该方法应用于制氢控制系统中的控制器，该制氢控制系统包括控制器，以及与该控制器连接的多个定位器，所述多个定位器与多个调节阀对应连接，用于根据所述控制器的控制信号控制所述调节阀，该调节阀位于该制氢控制系统中的氢氧分离器和储气装置之间的气体输送管道上，用于调节该氢氧分离器之间的压差；该控制器用于控制调节阀的开启或者关闭，该方法包括：
S101、获取制氢控制参数。
其中，该制氢控制参数包括制氢电流和最近时刻开启的调节阀的开度，该制氢电流为电解水的工作电流。
示例地，该制氢控制电流可以是通过预设的电流获取设备获取的该制氢控制系统的当前工作电流，该电流获取设备可以是电流传感器等设备，该调节阀的开度可以根据该调节阀对应的定位器确定。
S102、根据该制氢控制参数控制该多个调节阀开启或者关闭，以调节该制氢控制系统中氢氧分离器的压差。
在一种可能的实现方式中，由于该系统中氢分离器和氧分离器的气压取决于电解水的产气量，因此可以通过该系统电解水的制氢电流控制调节阀；则该制氢控制参数包括制氢电流，通过该制氢电流控制该多个调节阀的开启或者关闭。
示例地，获取该制氢电流和该制氢控制系统的额定电流的电流比例，以及该多个调节阀的调节阀数量；根据该调节阀数量确定一个或者多个预设比例阈值；根据该电流比例和该预设比例阈值，控制该调节阀开启或者关闭。
例如，该系统可以包括3个调节阀，在该系统开始进行制氢工作的情况下，会至少开启1个调节阀，而该系统以额定电流进行制氢工作的情况下，该3个调节阀的阀门会完全开启，在该系统以不同的实际制氢电流工作的情况下，所需要开启的阀门可能也会不同，因此，将该第一个开启的调节阀作为指定调节阀，然后可以根据该调节阀的数量设置2个预设比例阈值，分别 对应该指定调节阀外的2个调节阀，根据该系统的实际制氢电流和该额定电流的电流比例，控制该制定调节阀外的2个调节阀开启或者关闭。
在一些实施例中，在该多个调节阀对应的最大调节流量相同的情况下，将该调节阀数量与预设数量的差值作为该预设比例阈值的阈值数量；根据该调节阀数量和该阈值数量，确定该一个或者多个预设比例阈值，每个预设比例阈值对应一个调节阀。根据该预设比例阈值从小到大的顺序，在该电流比例大于该预设比例阈值的情况下，开启该预设比例阈值对应的调节阀。
如上述示例，该系统存在3个调节阀，记为调节阀1，调节阀2以及调节阀3，在设置该调节阀1为指定调节阀的情况下，在该系统开始进行制氢工作的情况下开启调节阀1，由于该指定调节阀为1个，因此该预设数量为1，可以确定该2个预设比例阈值，且该3个调节阀对应的最大调节流量相同，因此，可以确定该2个预设比例阈值分别为33％和67％，该调节阀2对应预设比例阈值为33％，该调节阀3对应预设比例阈值为67％，，在该电流比例小于或等于33％的情况下，只开启调节阀1，在该电流比例大于33％，且小于或等于67％的情况下，开启调节阀1和调节阀2，该电流比例大于67％的情况下，开启3个调节阀。在设置该调节阀1和调节阀2为指定调节阀的情况下，该指定调节阀为2个，即该调节阀1和该调节阀2在该系统开始进行制氢工作的情况下同时开启，则预设数量为2，可以确定1个预设比例阈值，且该3个调节阀对应的最大调节流量相同，则可以确定该调节阀3对应的预设比例阈值为67％，在该电流比例小于67％的情况下，开启该调节阀1和调节阀2，电流比例大于或等于67％的情况下，开启3个调节阀。
需要说明的是，实际生产中该指定调节阀一般情况下为1个，因此本申请后续实施例以1个指定调节阀为例，多个指定调节阀的情况参照上述示例简单变型，本申请不在赘述。另外，由于实际生产中存在参数跳变的情况，为了防止控制调节阀的制氢参数不稳定，因此可以采用预设比例阈值偏大的策略，以上述存在3个调节阀，1个指定调节阀为例，预设比例阈值可以将该2个比例阈值分别设置为35％和68％，以避免参数跳变导致的调节阀的频繁开启关闭。
这样通过电流比例控制调节阀的开启或关闭，减少了控制信号的数量， 有利于保障生产安全，提高制氢系统的工作效率。
在另一些实施例中，在该多个调节阀对应的最大调节流量不同的情况下，若该电流比例大于该预设比例阈值，确定指定调节阀是否开启；在该指定调节阀开启的情况下，按照预设调节阀开启顺序，开启其他调节阀，并关闭该指定调节阀；该其他调节阀为该多个调节阀中除该指定调节阀外的调节阀；在该指定调节阀关闭的情况下，开启该指定调节阀。
例如，该系统存在1个小调节阀和2个大调节阀，该大调节阀的最大调节流量是小调节阀的2倍，将该小调节阀作为指定调节阀，2个大调节阀分别为第一个开启的第一调节阀和第二个开启的第二调节阀；在该系统开始制氢的情况下，开启该小调节阀，并在电流比例达到第一个预设比例阈值的情况下，关闭小调节阀，开启第一调节阀；在该电流比例达到第二个预设比例阈值的情况下，开启小调节阀；在该电流比例达到第三个预设比例阈值的情况下，关闭小调节阀，开启第二调节阀；在电流比例达到第四个预设比例阈值的情况下，开启小调节阀。根据本示例调节阀的控制模式，可以得到该预设比例阈值的数量为调节阀数量减去指定调节阀数量之差的两倍，即4个，采用预设比例阈值偏大的策略，该预设比例阈值分别为22％、42％、62％和82％。
这样，通过设置小调节阀作为指定调节阀，通过开启或者关闭该小调节阀，提高该系统调节压差的精度，有利于提高生产效率。
在另一种可能的实现方式中，由于该系统中氢分离器和氧分离器的气压也取决于调节阀的阀门开度，因此，可以通过该调节阀开度控制调节阀的开启或者关闭。
示例地，该制氢控制参数包括最近时刻开启的调节阀开度，可以获取该最近时刻开启的调节阀的开度，通过最近开启的调节阀的开度控制该系统中调节阀的开启或者关闭。
在一些实施例中，在该多个调节阀对应的最大调节流量相同的情况下，根据该最近时刻开启的调节阀开度和预设调节阀开启顺序，开启调节阀。
示例地，在该最近时刻开启的调节阀的开度大于第一预设开度的情况下，按照预设调节阀开启顺序开启下一个调节阀。
例如，该第一预设开度可以是90％，在最近时刻开启的调节阀开度大于 90％的情况下，可以按照预设调节阀开启顺序，开启下一个调节阀。
这样，通过调节阀开度控制调节阀，控制逻辑简单明确，有利于保障系统的稳定性和安全性。
在另一些实施例中，在该多个调节阀对应的最大调节流量不同的情况下，根据最近时刻开启的该调节阀的开度和指定调节阀的状态，控制该调节阀开启或者关闭；该指定调节阀的状态包括开启或者关闭。
示例地，在最近时刻开启的该调节阀的开度大于第一预设开度阈值的情况下，确定该指定调节阀的状态；在该指定调节阀的状态为开启的情况下，按照预设调节阀开启顺序，开启其它调节阀，并关闭该指定调节阀；该其它调节阀包括该多个调节阀中除该指定调节阀之外的调节阀；在该指定调节阀的状态为关闭的情况下，开启该指定调节阀。
例如，存在两种最大调节流量不同的调节阀，将小调节阀作为指定调节阀，小调节阀的最大调节流量可以是大调节阀的1/4至1/2之间，以确保小调节阀可以达到目标控制精度的情况下，避免频繁开启关闭。在该制氢系统开始制氢的情况下，开启指定调节阀，在该指定调节阀的开度大于第一预设开度阈值的情况下，按照预设调节阀开启顺序，开启第一顺序调节阀，并关闭指定调节阀，在该第一顺序调节阀的开度大于第一预设开度阈值的情况下，开启指定调节阀，并在该指定调节阀的开度再次大于第一预设开度的情况下，开启第二顺序调节阀，关闭该指定调节阀。依次类图，直到开启全部调节阀。
这样，通过多个最大调节流量不同的调节阀进行流量调节，在保障系统安全的情况下，提升了控制精度，有利于提高生产效率。
此外，在该调节阀的开度小于或者等于第二预设开度阈值的情况下，关闭该调节阀；该第二预设开度阈值小于该第一预设开度阈值。
例如，该第二预设开度阈值可以在10％—20％之间，如10％、13％、15％、17％或者20％，此处不作限制，在该最近时刻的调节阀小于或者等于该第二预设开度阈值的情况下，关闭该调节阀。在存在两种最大调节流量不同的调节阀的情况下，在该小调节阀的开度小于或等于第二预设开度阈值的情况下，关闭该小调节阀；在该大调节阀开度小于或等于第二预设开度阈值的情况下，关闭该大调节阀，并开启作为指定调节阀的小调节阀。
采用上述方法，通过获取制氢控制参数，该制氢控制参数包括制氢电流和最近时刻开启的调节阀的开度，该制氢电流为电解水的工作电流；根据该制氢控制参数控制该多个调节阀开启或者关闭，以调节该制氢控制系统中氢氧分离器的压差。这样，通过制氢参数控制调节阀的开启或者关闭，有利于优化控制信号，减小氢氧分离器之间的压差，保障生产安全，提高制氢系统的工作效率。
