其中，在有主排风装置和备用排风装置的情况下，优先启动主排风装置，且在主排风装置正常运行的过程中，可对隔离病房内的负压值进行控制，使得隔离病房内的负压值保持在预设的目标负压值，使得负压能够保持稳定。
当主排风装置正常运行时，可实时获取压差传感器检测到的隔离病房内的第一静压值，需要说明的是，在本申请实施例中，将会涉及到第一静压值、第二静压值、第三静压值、第四静压值及第五静压值，其中的“第一”、“第二”、“第三”、“第四”及“第五”是用于对不同时刻或者不同场景下的静压值进行区分，并不对静压值本身造成限定。
进一步的，将根据第一静压值及预设的目标负压值，实时对主排风装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值。
在本申请实施例中，还将对主排风装置的运行进行监控，当监控到主排风装置出现故障时，将启动备用排风装置，且在备用排风装置正常启动之后，实时获取压差传感器检测到的隔离病房内的第二静压值，并根据该第二静压值与预设的目标负压值，对备用排风装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值。
需要说明的是，不论是使用主排风装置还是使用备用排风装置，对排风装置的风机转速的调整方式都是一样的，且目的均是使得隔离病房内的负压值保持在目标负压值。
在本申请实施例中，通过设置压差传感器，使得能够根据该压差传感器检测到的静压值及预设的目标负压值，对当前运行的排风装置的风机转速进行调整，使得隔离病房内的负压值能够保持在目标负压值，确保隔离病房内的负压值稳定，且在主排风装置的基础上还设置备用排风装置，使得在主排风装置出现故障的情况下，能够使用备用排风装置，增强了隔离病房的可靠性。
为了更好的理解本申请实施例中的技术方案，下面将从隔离病房的负压系统的启动，及启动之后控制隔离病房内的负压值保持在目标负压值等进行全面的描述。请参阅图2，为本申请实施例中，隔离病房的负压控制方法的流程示意图，该方法包括：
步骤201、接收负压系统启动指令，获取压差传感器检测到的隔离病房内的第三静压值；
步骤202、根据第三静压值启动主排风装置；

步骤212、实时获取压差传感器检测到的隔离病房内的第四静压值；
步骤213、根据第四静压值及预设的目标负压值，对备用排风装置的风机转速进行调整。
在本申请实施例中，隔离病房的负压系统包括但不限于主排风装置、备用排风装置、压差传感器及进风装置，若接收到负压系统启动指令，则将获取到压差传感器检测到的隔离病房内的第三静压值，并根据该第三静压值启动主排风装置。
其中，根据第三静压值启动主排风装置的方式具体可以是：利用该第三静压值查找预先设置的静压值与风机转速之间的映射关系，确定与该第三静压值对应的风机转速，并按照该第三静压值对应的风机转速启动主排风装置，即该第三静压值对应的风机转速为主排风装置的初始风机转速。其中该映射关系可以是通过大量实验确定的映射关系，或者也可以是通过机器学习算法训练得到的模型。其中，启动方式可以是向主排风装置发送启动指令，且该启动指令中包含上述的初始风机转速。且将进一步的判断主排风装置是否正常启动。
其中，主排风装置正常启动是指主排风装置能够启动，且在预设时长内达到初始风机转速。
当判断主排风装置能正常启动时，则将进一步启动进风装置，且由于需要形成负压，因此，需要在主排风装置启动之后，间隔预设时长，获取进风装置预设的第一风机转速，并按照该第一风机转速启动进风装置。且在进风装置完成启动之后，则表明完成了负压系统的启动。
上述是主排风装置能正常启动的情况下，通过启动主排风装置及进风装置实现负压系统的启动的过程，还有一种情况则是主排风装置不能正常启动，即主排风装置存在故障无法启动，负压系统的启动过程。
当主排风装置不能正常启动，则将根据第三静压值启动备用排风装置，其中，根据第三静压值启动备用排风装置的方式具体可以是：利用该第三静压值查找预先设置的静压值与风机转速之间的映射关系，确定与该第三静压值对应的风机转速，并按照该风机转速启动备用排风装置，即该第三静压值对应的风机转速为备用排风装置的初始风机转速。
且在启动备用排风装置之后，将间隔预设时长，获取进风装置预设的第一风机转速，并按照该第一风机转速启动进风装置。且在备用排风装置及进风装置都启动之后，则完成了负压系统的启动。
在本申请实施例中，负压系统启动之后，将进入负压系统的运行过程，且负压系统的运行过程也有两种情况，一种是主排风装置与进风装置在运行，另外一种是备用排风装置与进风装置在运行，下面将分别进行介绍。
（1）在负压系统启动时，启动的是主排风装置与进风装置场景下，将实时获取压差传感器检测到的隔离病房内的第一静压值，并根据该第一静压值及预设的目标负压值，对主排风装置的风机转速进行调整。
其中，对主排风装置的风机转速进行调整的具体方式可以为：根据第一静压值及预设的目标负压值，确定隔离病房内的负压值达到目标负压值所需要的风机风速调整值，根据该风机风速调整值对主排风装置的风机风速进行调整，使得隔离病房内的负压值保持在目标负压值。进一步地，可以为确定该第一静压值与预设的目标负压值的差值；根据该差值确定主排风机装置的风机转速的增大值或者减小值，该增大值或减小值即为上述的风机风速调整值；按照该增大值或减小值对主排风机装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值。其中，若差值对应的是增大值，则控制主排风装置在已有的风机转速的基础上增大，且增大上述的增大值，例如，若主排风装置已有的风机转速为A，增大值为B，则调整之后的风机转速为A+B。
其中，预先设置预设的静压差值与风机风速调整值之间的映射关系，因此，可以查找该映射关系，确定第一静压值与预设的目标负压值的差值对应的风机风速调整值，即上述的增大值或减小值，该静压差值与风机风速调整值之间的映射关系是通过大量实验确定的，或者基于机器学习算法训练得到的映射关系。
为了避免主排风装置出现故障，导致整个负压系统故障，还将对主排风装置进行检测，即检测主排风装置是否出现故障，当主排风装置出现故障时，则将启动备用排风装置，此时，启动备用排风装置的方式可以是：获取压差传感器检测到的第五静压值，根据该第五静压值查找预设的静压值与风机转速之间的映射关系，确定与该第五静压值对应的风机转速，并按照该第五静压值启动备用排风装置。因此，在主排风装置出现故障的情况下，可以使用备用排风装置替换主排风装置，避免负压系统及隔离病房因为主排风装置故障而无法使用，提高了隔离病房使用的可靠性。
且在使用备用排风装置替换主排风装置，且备用排风装置正常启动之后，将实时获取压差传感器检测到的隔离病房内的第二静压值，并根据该第二静压值及预设的目标负压值，对备用排风装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值。
其中，对备用排风装置的风机转速进行调整的方式可以为：根据第二静压值及预设的目标负压值，确定隔离病房内的负压值达到目标负压值所需要的风机风速调整值，根据该风机风速调整值对备用排风装置的风机风速进行调整，使得隔离病房内的负压值保持在目标负压值。进一步地，可以为确定该第二静压值与预设的目标负压值的差值，根据该差值确定备用排风机装置的风机转速的增大值或者减小值，该增大值或减小值即为上述的风机风速调整值；按照该增大值或减小值对备用排风机装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值。其中，若差值对应的是减小值，则控制备用排风装置在已有的风机转速的基础上减小，且增小上述的减小值，例如，若备用排风装置已有的风机转速为a1，减小值为b1，则调整之后的风机转速为a1-b1。
其中，预先设置预设的静压差值与风机风速调整值之间的映射关系，因此，可以查找该映射关系，确定第二静压值与预设的目标负压值的差值对应的风机风速调整值，即上述的增大值或减小值。
（2）在负压系统启动时，启动的是备用排风装置与进风装置场景下，将实时获取压差传感器检测到的隔离病房内的第四静压值，并根据该第四静压值及预设的目标负压值，对备用排风装置的风机转速进行调整。
其中，对备用排风装置的风机转速进行调整的方式可以为：确定该第四静压值与预设的目标负压值的差值，根据该差值确定备用排风机装置的风机转速的增大值或者减小值；按照该增大值或减小值对备用排风机装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值。其中，若差值对应的是减小值，则控制备用排风装置在已有的风机转速的基础上减小，且增小上述的减小值，例如，若备用排风装置已有的风机转速为a1，减小值为b1，则调整之后的风机转速为a1-b1。
其中，预先设置差值与风机调整转速之间的映射关系，因此，可以查找该映射关系，确定第四静压值与预设的目标负压值的差值对应的风机调整转速，即上述的增大值或减小值。
在本申请实施例中，在上述描述的多种场景或者情况下，还包括以下步骤：
当检测到隔离病房的开门指令时，将进风装置的风机转速从第一风机转速降低至预设的第二风机转速；
当检测到隔离病房的关门指令时，将进风装置的风机转速从第二风机转速增高至第一风机转速。
在本申请实施例中，考虑到隔离病房的门打开时，隔离病房内部的气压将与隔离病房外部的气压平衡甚至高于隔离病房外部的气压，导致隔离病房内部的污染气体向病房外输出，造成泄漏，因此，在检测到隔离病房的开门指令时，将进风装置的风机转速从第一风机转速降低至预设的第二风机转速，使得隔离病房内输入的空气量减少，即使在开门的时候，隔离病房内部的气压还是会小于隔离病房外部的气压。此外，当检测到隔离病房的关门指令时，则将进风装置的风机转速从第二风机转速增高至第一风机转速，使得进风装置的风机转速能够恢复正常。
进一步的，还将对压差传感器进行检测，当检测到压差传感器发生故障时，例如没有数据传输，则将控制当前运行的排风装置以预设的故障状态下的风机转速运行，并输出故障警告，使得能够及时对故障进行提醒，便于维护人员及时维护。
在本申请实施例中，通过设置压差传感器，使得能够根据该压差传感器检测到的静压值及预设的目标负压值，对当前运行的排风装置的风机转速进行调整，使得隔离病房内的负压值能够保持在目标负压值，确保隔离病房内的负压值稳定，且在主排风装置的基础上还设置备用排风装置，使得在主排风装置出现故障的情况下，能够使用备用排风装置，增强了隔离病房的可靠性。
请参阅图3，为本申请实施例中隔离病房的负压控制装置的结构示意图，负压控制装置用于对负压系统进行控制，隔离病房的负压系统包括：主排风装置、备用排风装置及压差传感器，负压控制装置包括：
获取模块301，用于当主排风装置正常运行时，实时获取压差传感器检测到的隔离病房内的第一静压值；
第一调整模块302，用于根据第一静压值及预设的目标负压值，对主排风装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值；
启动获取模块303，用于当检测到主排风装置故障时，启动备用排风装置，且在备用排风装置正常启动之后，实时获取压差传感器检测到的隔离病房内的第二静压值；
第二调整模块304，根据第二静压值及预设的目标负压值，对备用排风装置的风机转速进行调整，使得隔离病房内的负压值保持在目标负压值。
在本申请实施例中，通过设置压差传感器，使得能够根据该压差传感器检测到的静压值及预设的目标负压值，对当前运行的排风装置的风机转速进行调整，使得隔离病房内的负压值能够保持在目标负压值，确保隔离病房内的负压值稳定，且在主排风装置的基础上还设置备用排风装置，使得在主排风装置出现故障的情况下，能够使用备用排风装置，增强了隔离病房的可靠性。
