技术领域
本申请涉及空气净化设备技术领域，尤其涉及一种室内气压调整方法及装置。
 背景技术
随着医疗科技的技术发展，患者的治疗环境需求也越来越多。在对患者进行治疗的过程中，不同的患者有不同的气压环境需求，如患有空气传播疾病患者的治疗环境需为负压环境。如需进行保护性隔离或无菌治疗等的患者则需要正压环境进行治疗。如需进行一般空气净化的，仅仅需要常压的净化环境。因而需要针对不同的患者的治疗需求，有针对性的提供相应的治疗环境。
现有技术中是通过结合医疗设备建立特殊要求的病房以满足患者的治疗环境需求。然而这种方式不能灵活切换不同的气压环境，只能进行单独的控制，如建立正压病房单独控制正压或者建立负压病房单独控制负压，而且这种方式建设成本高。

 本发明的实施方式
本申请提供了一种室内气压调整方法及装置，用于解决现有技术中不能灵活切换室内不同气压环境且建设成本高的技术问题。
为使得本申请的发明目的、特征、优点能够更加的明显和易懂，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是本申请一部分实施例，而非全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
请参阅图1，图1为本申请实施例提供的一种室内气压调整方法的步骤流程图。
本申请实施例是应用于空气消毒设备，在介绍本申请实施例的方法之前，为了更好的了解本方法的实施过程，对应用到的空气消毒设备进行介绍如下。
请参阅图4，图4示出了应用到的空气消毒设备的结构示意图，其包括出风门和进风门，通过进风门接收外部气体，并对外部空气执行消毒操作，通过出风门输出。
需要说明的是，出风门包括内出风门和外出风门，进风门包括内进风门和外进风门；
外出风门对应设置于外出风口4，内出风门对应设置于内出风口3，内进风门对应设置于内进风口1，外进风门对应设置于外进风口2。外进风口2通过管道连接至室外，外出风口4通过管道连接至室外。为了以减少风口对风机风量的影响，内出风口3的开度面积加上外出风口4的开度面积等于内进风口1的开度面积加上外进风口2的开度面积。
其中，通过内进风门接收室内空气，通过外进风门接收室外的空气，并在设备内部进行对室内空气、室外空气进行消毒净化，将设备内部中的净化后的空气通过内出风门排至室内，通过外出风门排至室外。
空气消毒设备中设置有室内气压检测口5和室外气压检测口6，其中，室内气压检测口5通过检测管道与室内环境连通，室外气压检测口6通过检测管道与室外环境连通，在室内气压检测口5以及室外气压检测口6中放置微压差传感器，通过微压差传感器检测室内外的气压差值。
本申请实施例提供的一种室内气压调整方法具体可以包括以下步骤：
101、实时获取室内气压值和室外气压值。
需要说明的是，通过微压差传感器可以实时获取室内气压值和室外气压值的当前气压差值。
102、当接收到气压模式指令时，计算室内气压值与室外气压值的气压差值。
103、比较气压模式指令所对应的目标气压差值和气压差值，根据比较结果调整出风门和进风门的开启幅度，并实时监控气压差值。
需要说明的是，在调整风门的开启幅度之前，为了给后续通过控制风机转速维持气压稳定控制留有控制余量，可以将风机转速固定在预设速度，预设速度需小于风机转速的最大转速，而具体的预设速度可以根据实际的室内环境大小，风机型号确定。在本实施例中，预先将风机转速档位调整至中速档位。
需要说明的是，风门的开启幅度可以用百分比表示。根据比较结果控制电机动作，使风门达到相应的开启幅度位置，并通过电机反馈的增量编码确定风门的开启幅度是否达到相应的开启幅度位置。在风机速度固定的情况下，通过控制进、出风门的开启幅度相应地控制进、出风门的进风量、出风量，实现对室内气压的控制和切换。
需要说明的是，在进行风门开启幅度调整过程，空气消毒设备对通过进风门抽取至设备内部的空气进行消毒净化后，再通过出风门排至相应的环境中。
如当内进风门、内出风门和外出风门都处于打开的状态时，被抽取的室内空气通过内进风门流经空气消毒设备内部，在经过设备消毒净化后，通过内部相应的管道设置，从内出风门排至室内，从外出风门排至室外。室内、室外排风量的多少则分别由内出风门、外出风门的开启幅度相应地确定。
104、当气压差值等于目标气压差值时，停止调整开启幅度，并维持当前时刻的气压差值。
需要说明的是，根据比较结果调整出风门和进风门的开启幅度，并实时监控气压差值，判断气压差值是否达到目标气压差值。并在监控到的气压差值达到目标气压差值时，停止调整进、出风门的开启幅度，并固定当前时刻各风门的开启幅度。
在停止开启幅度的调整后，通过控制风机转速控制风量使当前时刻的气压差值维持在目标气压差值，维持室内气压平衡。
本申请实施例中，通过实时获取室内气压值和室外气压值，当接收到气压模式指令时，计算室内气压值与室外气压值的气压差值，比较气压模式指令所对应的目标气压差值和气压差值，根据比较结果调整出风门和进风门的开启幅度，并实时监控气压差值，当气压差值等于目标气压差值时，停止调整开启幅度，并维持当前时刻的气压差值，在通过风门开启幅度调节实现气压控制的过程中，有针对性的对室内气体环境进行消毒净化，使空气消毒设备实现不同气压模式的控制与切换，同时还能实现室内环境的消毒净化，更好的满足不同的医疗环境需求，而且通过控制风门的开启幅度进行不同气压环境之间的切换，建设成本更低。
请参阅图2，图2为本申请另一实施例提供的一种室内气压调整方法的步骤流程图。本方法应用于空气消毒设备中，空气消毒设备包括出风门和进风门，通过进风门接收外部气体，并对外部空气执行消毒操作，通过出风门输出。空气消毒设备还包括风机，方法具体可以包括以下步骤：
200、响应于接收到的设备启动指令，对进风门和出风门执行故障检测步骤。
其中，故障检测步骤包括：通过预设的电机驱动进风门和/或出风门执行风门调控动作，并累计动作执行时间，其中风门调控动作包括开门动作和关门动作；
在执行风门调控动作期间，若未接收到电机返回的增量编码反馈信号，则生成电机故障信号并显示；
在执行关门动作期间，若接收到的电机增量编码反馈信号且关门动作执行时间大于预设时间阈值，则生成限位开关故障信号并显示；否则输出工作正常信号。
需要说明的是，在执行风门调控动作期间，若未接收到电机增量编码反馈信号，说明电机发生故障，此时，生成电机故障信号并显示，提醒用户电机发生故障。
当接收到电机增量编码反馈时，说明电机可以正常工作，在此基础上，电机驱动风门执行关门动作，当电机启动后，累计关门动作执行时间，当接收到限位开关反馈的风门关闭到位的信号时，停止计时。当关门动作执行时间累计到大于预设时间阈值时，风门的关门动作超时，说明未接收到限位开关的反馈风门关闭到位信号，限位开关发生故障，此时生成限位开关故障信号并显示，提醒用户当前限位开关已发生故障。其中，以接收到限位开关反馈的信号为准停止对关门动作计时。当关门动作执行时间等于或小于预设阈值，说明限位开关正常，输出限位开关正常信号。
201、实时获取室内气压值和室外气压值；
需要说明的是，参考步骤101，此处不再赘述。
出风门和进风门均设置相同的预设开启幅度。
其中，出风门包括至少一个内出风门和至少一个外出风门；进风门包括至少一个内进风门和至少一个外进风门。
需要说明的是，可以根据设备以及现实环境的实际情况，设置各风门的数量以及各个风门的尺寸。如内出风门、内进风门、外出风门、外进风门的数量可以均设置为1个，尺寸大小均为600mm*200mm，参阅图4，图4示出了内出风门、内进风门、外出风门、外进风门均设置为1个的情况，且示出了具体的设置位置。
内进风门、内出风门、外出风门、外进风门均设置相同的预设开启幅度。
需要说明的是，在执行气压模式指令时，可以预先为内进风门、内出风门、外出风门、外进风门设置相同的开启幅度，以便进行后续的调整。预设的开启幅度作为调整的基础幅度，其可以根据实际需求预先设定。例如设定的规则可以根据目标气压差值的大小设定，当目标气压值比实际的气压差值大时，可以适当设定较大的开启幅度作为后续开启幅度调整的基础，如均设定为50%或60%。
202、当接收到气压模式指令时，计算室内气压值与室外气压值的气压差值。
需要说明的是，具体可参考步骤102，此处不再赘述。
203、当气压模式指令为正压模式指令时，比较正压模式指令所对应的目标气压差值和气压差值，根据比较结果调整出风门和进风门的开启幅度，包括：
当气压模式指令为正压模式指令；将内出风门的开启幅度调整至最大幅度，将外出风门的开启幅度调整至最小幅度。
需要说明的是，当接收的气压模式指令为正压模式指令时，将内出风门的开启幅度调整至最大幅度，将外出风门的开启幅度调整至最小幅度，即关闭外出风门。
比较正压模式指令所对应的目标气压差值和气压差值；
若气压差值小于目标气压差值，根据第一预设调整幅度增加外进风门的开启幅度以及减小内进风门的开启幅度；
若气压差值大于目标气压差值，根据第二预设调整幅度减小外进风门的开启幅度以及增加内进风门的开启幅度。
需要说明的是，第一预设调整幅度和第二预设调整幅度可以根据实际情况预先设定，如第一预设调整幅度可以根据外进风门的开启幅度大于内进风门且外进风门与内进风门的开启幅度总和为100%的规则确定，第二预设调整幅度可以根据外进风门的开启幅度小于内进风门且外进风门与内进风门的开启幅度总和为100%的规则确定。
第一预设调整幅度包括外进风门增加的开启幅度、内进风门减小的开启幅度；第二预设调整幅度包括外进风门减小的开启幅度、内进风门增加的开启幅度。在各风门预先设定的开启幅度基础上，根据目标气压差值与计算得到的室内与室外的实际气压差值的比较结果，循环地、动态地调整内进风门、外进风门的开启幅度。
例如，预先将外进风门和内进风门的开启幅度均调整至50%，第一预设调整幅度、第二预设调整幅度均设定为5%，比较当前时刻的气压差值和目标气压差值，若当前时刻计算得到的气压差值小于目标气压差值，降低5%幅度的内进风门的开启幅度，提高5%幅度的外进风门的开启幅度，使得外进风门的开启幅度大于内进风门的开启幅度，此时，内进风门的开启幅度为45%，外进风门的开启幅度为55%，恰好保持外进风门的开启幅度和内进风门的开启幅度总和为100%。若当前时刻计算得到气压差值大于目标气压差值，则减低5%幅度的外进风门的开启幅度，提高5%幅度的内进风门的开启幅度，使内进风门的开启幅度大于外进风门的开启幅度，此时内进风门的开启幅度为55%，外进风门的开启幅度为45%。实时监控室内与室外的气压差值，并根据气压差值的比较结果，动态调整和修正内进风门、外进风门的开启幅度，使得室内与室外之间的气压差值达到目标气压差值。
此时，在执行正压模式指令时，空气消毒设备内部将通过内进风门接收的室内风和通过外进风门接收的室外风进行混合，并对混合风进行消毒净化后，通过内出风门输出至室内。因此在本实施例中，通过控制各个风门的开启幅度使得室内气压环境达到患者所需的正压环境，同时在进行控制的过程中，对经过消毒设备的空气进行消毒净化后，再排进室内，提高了室内环境的无菌程度，为患者提供更加安全、可靠的治疗环境。
204、当气压模式指令为负压模式指令时，比较负压模式指令所对应的目标气压差值和气压差值，根据比较结果调整出风门和进风门的开启幅度，包括：
当气压模式指令为负压模式指令时，将内进风门的开启幅度调整至最大幅度，将外进风门的开启幅度调整至最小幅度；
需要说明的是，当接收到的气压模式指令为负压模式指令时，将内进风门打开至最大，关闭外进风门。
比较负压模式指令所对应的目标气压差值和气压差值；
若气压差值大于目标气压差值，根据第三预设调整幅度增加外出风门的开启幅度以及减小内出风门的开启幅度；
若气压差值小于目标负压差值，根据第四预设调整幅度减小外出风门的开启幅度以及增加内出风门的开启幅度。
需要说明的是，第三预设调整幅度、第四预设调整幅度可以根据实际的情况设定的，如第三预设调整幅度可以根据外出风门的开启幅度大于内出风门且外出风门与内出风门的开启幅度总和为100%的规则确定，第四预设调整幅度可以根据外出风门的开启幅度小于内出风门且外出风门与内出风门的开启幅度总和为100%的规则确定。在预先设定的开启幅度基础上，根据目标气压差值与计算得到的室内与室外的实际气压差值的比较结果，基于第三预设调整幅度或第四预设调整幅度循环地、动态地调整内出风门、外出风门的开启幅度。
例如，预先将外出风门和内出风门的开启幅度均调整至50%，第三预设调整幅度、第四预设调整幅度均设定为5%，比较当前时刻的气压差值和目标气压差值，若当前时刻计算得到的气压差值大于目标气压差值，降低5%幅度的内出风门的开启幅度，提高5%幅度的外出风门的开启幅度，使得外出风门的开启幅度大于内出风门的开启幅度，此时，内出风门的开启幅度为45%，外出风门的开启幅度为55%。若当前时刻计算得到气压差值小于目标气压差值，则减低5%幅度的外出风门的开启幅度，提高5%幅度的内出风门的开启幅度，使内出风门的开启幅度大于外出风门的开启幅度，此时内出风门的开启幅度为55%，外出风门的开启幅度为45%。实时监控室内与室外的气压差值，并根据气压差值的比较结果，动态调整和修正内出风门、外出风门的开启幅度，使得室内与室外之间的气压差值达到目标气压差值。
此时，在执行负压模式指令时，空气消毒设备内部将通过内进风门接收的室内风进行消毒净化后，通过内出风门输出至室内，通过外出风门排出室外。因此在本实施例中，通过控制各个风门的开启幅度使得室内气压环境达到患者所需的负压环境，同时在进行控制的过程中，对经过消毒设备的空气进行消毒净化后，再相应的排进室内以及排出室外，提高了室内环境的无菌程度，为患者提供更加安全、可靠的治疗环境，同时避免室内气体污染外界环境。
需要说明的是，在本申请的另一实施例中，当内出风门、外出风门、内进风门、外进风门均有多个时，实时获取计算到的实际气压差值与目标气压差值之间的差值，在固定的风机转速情况下，预先分别建立差值与第一预设调整幅度、第二预设调整幅度、第三预设调整幅度、第四预设调整幅度之间的对应关系，根据对应关系确定各个风门的目标调整幅度。
205、当气压差值等于目标气压差值时，停止调整开启幅度，并维持当前时刻的气压差值的步骤，包括：
当气压差值等于目标气压差值时，停止调整开启幅度；
若当前时刻的气压差值出现变化，则获取当前时刻的气压差值的变化值，结合预设的风机转速调整关系计算目标转速；
将风机的当前转速调整为目标转速，使当前时刻的气压差值维持在目标气压差值。
需要说明的是，室内与室外之间的实际气压差值达到目标气压值，固定当前时刻的各风门的开启幅度，此时室内气压可能会出现波动、不平衡的情况导致实际压差值出现微小变动，通过获取实际气压差值的变化值，根据变化值与风机转速调整关系计算目标转速，并将风机当前的转速调整至目标转速，因而此时可以通过控制风门电机转速控制排风量，对室内环境气压进行微调，使气压差值维持在目标气压值，以维持气压平衡。
具体地，可以预先通过PID控制模型建立变化值与风机转速调整关系，并计算出目标转速，或者通过其他的数学模型训练出变化值与风机转速调整关系。
在本申请的另一实施例中，还包括：当气压模式指令为内循环指令时，
将内进风门的开启幅度调整至最大幅度；
将内出风门的开启幅度调整至最大幅度；
将外进风门的开启幅度调整至最小幅度；
将外出风门开启幅度调整至最小幅度。
需要说明的是，当接收到气压模式指令是内循环指令时，说明需要对室内气体进行内循环净化，因此将内进风门的开启幅度调整至最大幅度，将内出风门的开启幅度调整至最大幅度，将外进风门的开启幅度调整至最小幅度，将外出风门开启幅度调整至最小幅度。
此时，空气消毒设备对通过内进风门接收的室内风进行消毒净化后，通过内出风门排至室内，实现室内环境的循环净化。
在本申请的另一实施例中，室内气压调整方法还包括选取开启幅度最小的出风门和/或进风门作为第一待检测风门；
判断第一待检测风门是否触碰到限位开关，若是，则生成风门动作到位信号；若否，则控制第一待检测风门执行故障检测步骤；
选取除第一待检测风门以外的出风门和/或进风门作为第二待检测风门；
当接收到电机增量编码反馈信号时，根据电机增量编码反馈信号判断第二待检测风门的开启幅度是否达到目标开启幅度，若是，则生成风门动作到位信号；若否，则控制第二待检测风门执行故障检测步骤。
其中，故障检测步骤包括：通过预设的电机驱动进风门和/或出风门执行风门调控动作，并累计动作执行时间，其中风门调控动作包括开门动作和关门动作；
在执行风门调控动作期间，若未接收到电机返回的增量编码反馈信号，则生成电机故障信号并显示；
在执行关门动作期间，若接收到的电机增量编码反馈信号且关门动作执行时间大于预设时间阈值，则生成限位开关故障信号并显示；否则输出工作正常信号。
需要说明的是，在对进风门、出风门进行开启幅度调整时，实时检测风门的运行状态是否出现故障，并出现故障时，及时反馈故障信息，避免因设备故障导致气压模式切换失败情况。
例如在执行正压模式指令时，第一待检测风门为外出风门。当将外出风门的开启幅度调整至最小幅度时，通过判断外出风门是否与限位开关相连，若是，则生成风门动作到位信号，说明外出风门已经调整到位，否则控制外出风门执行故障检测步骤。
第二待检测风门为内出风门、内进风门、外进风门，当接收到电机增量编码反馈信号时，根据电机增量编码反馈信号判断第二待检测风门的开启幅度是否达到目标开启幅度，若是，则生成风门动作到位信号；若否，则控制第二待检测风门执行故障检测步骤。其中，内出风门的目标开启幅度为最大幅度，内进风门、外进风门的目标开启幅度则为最近一次调整后的开启幅度。
在本实施例中，通过实时监控各风门的运行状态，并在出现故障时及时反馈，方便工作人员及时进行维护，避免因为设备故障导致气压调整失败的情况。
