Description

一种用于空调器的粉尘监测装置、空调器及其控制方法 技术领域
本发明涉及空气调节设备技术领域,尤其涉及一种空调器用激光PM2.5传感器的控制方法,以及采用上述控制方法的空调器。
背景技术
在当前粉尘颗粒PM2.5检测领域中,PM2.5检测仪主要采用两种粉尘传感器:红外粉尘传感器和激光粉尘传感器。其中红外粉尘传感器的结构和电路比较简单,其光源为红外LED光源,气流进出风口主要靠电阻发热以使得气流流动,如果有颗粒通过即输出高电平,从而检测颗粒浓度。
技术问题
由于红外LED光散射的颗粒信号较弱,只对1μm以上的大颗粒有响应,因此红外粉尘传感器只能检测到1μm以上的颗粒,实际测量精度比较低。而且,红外粉尘传感器仅用加热电阻来推动采样气流,采样数比较少,数据计算精度也较差。二者累加效应使得红外粉尘传感器的采样精度完全无法满足PM2.5颗粒的检测需求。而激光粉尘传感器的检测精度较高。但是,激光粉尘传感器本身采用激光二极管进行检测,寿命相对较短。导致无法在空调器领域大批量应用。
技术解决方案
为解决现有技术中红外粉尘传感器的检测精度不足,激光粉尘传感器的寿命较短,无法与空调器寿命匹配的问题,本发明公开了一种空调器用激光粉尘传感器的控制方法。

设定空调器平均制冷使用周期P c和/或设定空调器平均制热使用周期P h
设定空调器平均日使用时长T P1
设定空调器平均使用寿命T P2
根据所述平均制冷使用周期、平均制热使用周期、平均日使用时长、平均使用寿命计算平均连续监控状态周期T P3=(P c+P h)× T P1×T P2
计算平均待机状态周期T P4=(P c+P h)× (24- T P1)×T P2+(365- P c-P h)×24×T P2
 根据平均激光粉尘传感器使用寿命T 0、平均连续监控状态周期、平均待机状态周期计算待机状态下激光粉尘传感器每小时的最大允许工作时间T,其中T=(T 0- T P3)/ T P4×60;
设定所述设定工作周期的最大值T max, 所述设定间隔周期预设值t=60/T/T max
优选的。所述设定工作周期的最大值T max等于所述第一工作周期。
本发明所公开的用于空调器的粉尘监测装置可以由控制器根据空调房间内的空气质量以及空调器的使用状态智能控制激光粉尘传感器的启停,在空调房间无人或者用户主观感受舒适,且空气质量较好的情况下,智能控制减少激光粉尘传感器的工作时间,延长其使用寿命;在空调房间无人或者用户主观感受舒适,且空气质量较差的情况下,智能相对提高激光粉尘传感器的工作时间,达到使用效果和工作时间的平衡。从长期使用角度上看,使得激光粉尘传感器的使用寿命和空调器的使用寿命匹配,中途无需更换,促进激光粉尘传感器可以大面积推广使用。

如图1所示,粉尘监测装置100包括激光粉尘传感器102,以及用于控制激光粉尘传感器的控制器101。控制器101同时还接收激光粉尘传感器102的检测信号。在本发明所公开的用于空调器的粉尘监测装置中,粉尘监测装置的启停和检测过程由控制器控制自动完成,无需人为干预。粉尘监测装置设置在空调器室内机上或者与空调器室内机建立远程通讯。
如图2所示,在粉尘监测装置的运行过程中,激光粉尘传感器的启动或关闭根据空调器的工作状态进行控制。如果空调器处于开机状态,则控制器控制激光粉尘传感器处于连续监控状态,形成连续的监测信号,空调器室内机控制芯片可以及时获得监测参数,并利用粉尘监测装置的检测结果进行下一步智能控制。如空调器设定有与新风系统联动的程序,则可以控制新风系统运行,对室内进行换新风处理,改善室内空气质量,如空调器与空气净化器联动,则可以控制空气净化器运行,对室内空气进行净化处理。
当空调器处于待机状态时,通常为室内无人,或者用户感觉到舒适的状态。在这种状态下,控制激光粉尘传感器处于间隔监控状态。如图4所示,在步骤S302中,控制器中的待机周期计时器开始工作。在步骤S303中,判定待机周期计时器的计时时间是否大于设定间隔周期预设值;如果待机周期计时器的计时时间大于设定间隔周期预设值时,则在步骤S304中,控制器控制激光粉尘传感器开启,同时工作周期计时器开始计时。在控制激光粉尘传感器开启的同时,控制器采样一个激光粉尘传感器的检测值,并如步骤S305所示,根据检测值预先判定当前室内条件下的空气质量,如果当前空气质量相对良好,则适当的减少激光粉尘传感器的开启时间,以使得长期使用时,激光粉尘传感器的使用寿命尽量与空调器的使用寿命匹配;如果当前空气质量相对较差,则需要激光粉尘传感器保持相对较长的工作时间。因此,优选的,设定工作周期预设值与激光粉尘传感器的检测值正相关。即如果激光粉尘传感器的检测值PM2.5的浓度较高,则生成的设定工作周期预设值较大,如果激光粉尘传感器的检测值PM2.5的浓度较低,则生成的设定工作周期预设值较小。在步骤S305中,控制器根据激光粉尘传感器开启时接收到的检测值生成设定工作周期预设值,并进一步判定工作周期计时器的计时时间是否大于设定工作周期预设值。当工作周期计时器的计时时间大于设定工作周期预设值时,在步骤S306中,控制器控制激光粉尘传感器关闭。通过上述方式,可以由控制器根据空调房间内的空气质量以及空调器器的使用状态智能控制激光粉尘传感器的启停,在空调房间无人或者用户主观感受舒适,且空气质量较好的情况下,智能控制减少激光粉尘传感器的工作时间,延长其使用寿命并与空调器的使用寿命匹配;在空调房间无人或者用户主观感受舒适,且空气质量较差的情况下,智能相对提高激光粉尘传感器的工作时间,达到使用效果和工作时间的平衡。上述实施例所提供的用于空调器的粉尘监测装置具有智能化程度高的优点。控制器可以是一颗单片机,或者其它类似的可以实现同样功能的集成电路或者控制设备。待机周期计时器和工作周期计时器可以是独立的计时电路,也可以是单片机的计时器中断,不是本发明的保护重点,在此不做进一步限定。
优选的,在步骤S07中,控制器控制激光粉尘传感器关闭时,控制器清零待机周期计时器,待机周期计时器重新开始计时。这样,即使空调器处于待机状态而空调房间的空气质量发生连续变化,也能在每一个周期中响应空气质量的连续变化,对激光粉尘传感器的工作周期进行灵活的调整。
具体来说,生成设定工作周期时。在控制器中存储有检测值的设定区间。如果判定激光粉尘传感器的检测值属于第一区间时,设定工作周期预设值为第一工作周期;如果判定激光粉尘传感器的检测值属于第二区间时,设定工作周期预设值为第二工作周期;如果判定激光粉尘传感器的检测值属于第三区间时,设定工作周期预设值为第三工作周期。其中第一区间、第二区间和第三区间保持递减的趋势,具体来说,即为第一区间、第二区间和第三区间的下限阈值依次递减。第一区间、第二区间和第三区间的区间长度可以是设定为相同的,也可以设定为递增或递减的。如果采用递增的设置方式,则更为注重保持激光粉尘传感器合理的工作时间,而如果采用递减的设置方式,则更为注重保证激光粉尘传感器的监测效果。如果第一区间、第二区间和第三区间的设定长度相同,则优选的,对应的第一工作周期、第二工作周期和第三工作周期等梯度递减,以保证监测结果平稳,避免波动。举例来说,可以设定第一区间为,375ppm>PM2.5>250ppm,第一工作周期为3分钟,第二区间为,250ppm>PM2.5>125ppm,第二工作周期为2分钟,第三区间为,125ppm>PM2.5>0ppm,第三工作周期为1分钟。
设定间隔周期预设值可以通过经验设置。但更为优选的,通过以下方式生成, 如图3所示:
步骤S201,设定空调器平均制冷使用P c和/或设定空调器平均制热使用周期P h。其中,空调器平均制冷使用周期P c和/或空调器平均制热使用周期P h可以通过大数据服务器调用空调器使用区域的用户平均数据得到。空调器平均制冷使用周期P c和空调器平均制热使用周期P h的单位为日。
步骤S202,设定空调器平均日使用时长T P1,空调器平均日使用时长T P1可以使用用户空调器账号在服务器上查询得到。空调器平均日使用时长T P1的单位为小时。
步骤S203, 设定空调器平均使用寿命T P2,空调器平均使用寿命寿命T P2通过实验得到,优选是一个经验值。空调器平均使用寿命T P2为年。
步骤S204, 根据所述平均制冷使用周期、平均制热使用周期、平均日使用时长、平均使用寿命计算平均连续监控状态周期T P3=(P c+P h)× T P1×T P2。平均连续监控状态周期T P3的单位为小时。
步骤S205, 进一步计算平均待机状态周期T P4=(P c+P h)× (24- T P1)×T P2+(365- P c-P h)×24×T P2
步骤S206,根据平均激光粉尘传感器使用寿命T 0、平均连续监控状态周期、平均待机状态周期计算待机状态下激光粉尘传感器每小时的最大允许工作时间T,其中T=(T 0- T P3)/ T P4×60。
步骤S207, 设定所述设定工作周期的最大值T max, 所述设定间隔周期预设值t=60/T/T max
举例来说,通过调用大数据服务器的数据可以得到空调器在某个地理区域,平均在夏季使用90日,冬季使用90日,设置有粉尘监测装置的空调器的平均日使用时长T P1为15小时,空调器平均使用寿命寿命T P2为6年。则可以得到平均连续监控状态周期T P3=(90+90)× 15×6=16200小时。
进一步可以得到平均待机状态周期T P4=(90+90)× (24- 15)×6+(365- 90-90)×24×6=36360小时。
对于某一型号的激光粉尘传感器来说,平均激光粉尘传感器使用寿命T 0为27000小时,则进一步可以计算出待机状态下激光粉尘传感器每小时的最大允许工作时间T, T=(27000- 16200)/ 36360×60≈18分钟。
设定一个设定工作周期的最大值T max。优选的,设定工作周期的最大值T max与第一工作周期相等,代表间隔运行状态下,污染情况最为严重时的允许工作时间。优选设定为3分钟。设定间隔周期预设值t= 60/18/3=10分钟。
采用这种方式,生成设定间隔周期预设值时,充分的考虑了粉尘监测装置使用区域、设置有粉尘监测装置的空调器的使用习惯、激光粉尘传感器的型号特性,生成的设定间隔周期预设值更为合理,合理保护激光粉尘传感器,使其使用寿命和空调器的使用寿命相匹配。
本发明同时还保护了一种空调器,包括如上述实施例和说明书附图详细描绘的粉尘监测装置。粉尘监测装置的具体结构和工作过程参见上述实施例的详细描述,在此不再赘述,设置有上述粉尘监测装置的空调器可以实现同样的技术效果。

根据激光粉尘传感器开启时的检测值生成设定工作周期预设值,当所述工作周期计时器的计时时间大于设定工作周期预设值时,控制激光粉尘传感器关闭。
优选的,其中的设定间隔周期预设值也采用如图3的方法生成。
综上所述,本发明所公开的用于空调器的粉尘监测装置、空调器和粉尘监测装置的控制方法可以由控制器根据空调房间内的空气质量以及空调器的使用状态智能控制激光粉尘传感器的启停,在空调房间无人或者用户主观感受舒适,且空气质量较好的情况下,智能控制减少激光粉尘传感器的工作时间,延长其使用寿命;在空调房间无人或者用户主观感受舒适,且空气质量较差的情况下,智能相对提高激光粉尘传感器的工作时间,达到使用效果和工作时间的平衡。从长期使用角度上看,使得激光粉尘传感器的使用寿命和空调器的使用寿命匹配,中途无需更换,促进激光粉尘传感器可以大面积推广使用。
