Description

一种自动化灌溉控制方法及装置
本申请要求于2018年04月28日提交中国专利局、申请号为201810404199.2、发明名称为“一种自动化灌溉控制方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及农业技术领域,特别涉及一种自动化灌溉控制方法及装置。
背景技术
温室,又称暖房,能透光、保温(或加温),用来栽培植物。在不适宜植物生长的季节,能提供温室生育期和增加产量,多用于低温季节喜温蔬菜、花卉、林木等植物栽培或育苗等。植物的生长离不开供水,因此灌溉装置为温室中的重要组成部分。为了方便灌溉,减少人力,现有技术在温室中设置自动化灌溉装置,自动化灌溉装置能够按照预设灌溉程序在指定时段对温室植物进行间歇性灌溉。
本申请的发明人发现现有技术中至少存在如下问题:现有技术的自动化灌溉过程中,灌溉量不易控制,容易造成灌溉量过低无法满足植物的生长需求、或灌溉量过高导致资源浪费的问题。
技术问题
本申请的目的在于提供一种自动化灌溉控制方法及装置,实现了作物的合理灌溉,既保证灌溉量满足植物的生长需求,又避免灌溉过多而造成资源浪费。
技术解决方案
本申请的一个实施例提供了一种自动化灌溉控制方法,包括启动间歇性灌溉,所述间歇性灌溉包括,当辐射累积量大于或等于预设辐射阈值时,启动灌溉,其中,每次灌溉后,控制灌溉的辐射累积量归零、并重新开始计算灌溉的辐射累积量;在间歇性灌溉过程中检测第一特征值是否大于或等于预设阈值,若是,停止所述间歇性灌溉,其中,所述第一特征值用于表征灌溉液体未被植物吸收的程度;计算所述间歇性灌溉的停止时间与日落时间之间的差值,若所述差值大于第一预设时长,则在日落时间之前再启动一次灌溉。
本申请的一个实施例还提供了一种服务器,包括:至少一个处理器;以及,与至少一个处理器通信连接的存储器;其中,存储器存储有可被至少一个处理器执行的指令,指令被至少一个处理器执行,以使至少一个处理器能够执行上述的自动化灌溉控制方法。
本申请的一个实施例还提供了一种计算机可读存储介质,存储有计算机程序,所述计算机程序被处理器执行时实现上述的自动化灌溉控制方法。
另外,所述预设辐射阈值包括第一辐射阈值和第二辐射阈值,其中,当辐射累积量大于或等于第一辐射阈值时,启动灌溉,为第一阶段;或当辐射累积量大于或等于第二辐射阈值、或在预设时间内没有启动灌溉时,启动一次灌溉,为第二阶段;或在日出时间后预设时长时,启动一次灌溉,为第三阶段。通过将一天分为三个阶段,分别采用三种不同的控制方式,使得所述灌溉能够更加符合植物在一天中各个时间段的灌溉需求,从而更有利于植物生长。
另外,所述第一辐射阈值为预先设定的辐射量的定值,或为与上一次灌溉经过的时长成正相关的变量。当所述第一辐射阈值为与上一次灌溉经过的时长成正相关的变量时,随着时间的推移,所述第一辐射阈值越来越大,从而使得灌溉频率越来越小,能够更加符合下午植物蒸腾作用越来越弱、所需的水分越来越少的情景,防止灌溉过多浪费资源。
另外,当所述第一辐射阈值为与上一次灌溉经过的时长成正相关的变量时,具体为:所述第一辐射阈值Y 1或Y 2,其中,Y 1=200+5/6*X,Y 2=300+5/3*X,X为上一次灌溉时间与第一阶段开启时间之间的差值。
另外,所述第二辐射阈值为预先设定的辐射量的定值。
另外,所述第一特征值为排液量与灌溉量之间的比值。如此设置,能够较为准确的判断灌溉是否过量,更有利于合理的灌溉。
另外,所述启动间歇性灌溉的步骤之后,还包括:在日落时间前第二预设时长时,检测所述间歇性灌溉是否停止,若否,则停止所述间歇性灌溉,所述第二预设时长小于所述第一预设时长;所述若所述差值大于第一预设时长,则在日落时间之前再启动一次灌溉的步骤,具体为:在日落时间前第二预设时长之前,再启动一次灌溉。如此设置,使得在日落时间前第二预设时长之后,不会再对植物进行灌溉,从而减少了在夜间湿度过大导致植物烂根的问题。
另外,所述停止所述间歇性灌溉的步骤之前,还包括:发送预警信息以提示工作人员。如此设置,能够在灌溉液体很大程度未被植物吸收时,提醒工作人员前往查看,有利于及时发现并解决问题。
有益效果
本申请实施例相对于现有技术而言,通过在辐射累积量大于或等于预设辐射阈值时,启动灌溉,并且在每次灌溉后,控制灌溉的辐射累积量归零、并重新开始计算灌溉的辐射累积量,从而在每次辐射累积量达到预设辐射阈值时,都能启动灌溉,也就是说,辐射越大,相应的灌溉就越频繁,由于在辐射较大时、植物蒸腾作用增强,消耗更多的水分,所以,该间歇性灌溉能够更好的满足植物的生长需求;通过在间歇性灌溉过程中检测第一特征值是否大于或等于预设阈值,当第一特征值大于或等于预设阈值时,说明灌溉液体未被植物充分吸收,则停止所述间歇性灌溉,从而避免了灌溉过量,造成资源的浪费;通过计算所述间歇性灌溉的停止时间与日落时间之间的差值,当所述差值大于第一预设时长时,植物在日落之前还是需要灌溉溶液的补充的,则在日落时间之前再启动一次灌溉,从而避免了灌溉太少,影响植物生长,从而实现合理灌溉,既保证植物的生长需求,又避免资源浪费。

本申请涉及一种自动化灌溉控制方法,本实施方式的核心在于:启动间歇性灌溉;在间歇性灌溉过程中检测第一特征值是否大于或等于预设阈值,若是,停止所述间歇性灌溉,其中,所述第一特征值用于表征灌溉液体未被植物吸收的程度;计算所述间歇性灌溉的停止时间与日落时间之间的差值,若所述差值大于第一预设时长,则在日落时间之前再启动一次灌溉。通过在间歇性灌溉过程中检测第一特征值是否大于或等于预设阈值,当第一特征值大于或等于预设阈值时,说明灌溉液体未被植物充分吸收,则停止所述间歇性灌溉,从而避免了灌溉过量,造成资源的浪费;通过计算所述间歇性灌溉的停止时间与日落时间之间的差值,当所述差值大于第一预设时长时,说明植物在日落之前还是需要灌溉溶液的补充的,则在日落时间之前再启动一次灌溉,从而避免了灌溉太少,影响植物生长,从而实现合理灌溉,既保证植物的生长需求,又避免资源浪费。
下面对本实施方式的自动化灌溉控制方法的实施细节进行具体的说明,以下内容仅为方便理解提供的实施细节,并非实施本方案的必须。
本实施方式中的自动化灌溉控制方法,如图1所示,具体包括:
S101:启动间歇性灌溉。
具体的说,在步骤S101中,所述间歇性灌溉包括,当辐射累积量大于或等于预设辐射阈值时,启动灌溉,其中,每次灌溉后,控制灌溉的辐射累积量归零、并重新开始计算灌溉的辐射累积量。所述预设辐射阈值包括第一辐射阈值和第二辐射阈值,其中,当辐射累积量大于或等于第一辐射阈值时,启动灌溉,为第一阶段;或当辐射累积量大于或等于第二辐射阈值、或在预设时间内没有启动灌溉时,启动一次灌溉,为第二阶段;或在日出时间后预设时长时,启动一次灌溉,为第三阶段。通过将一天分为三个阶段,分别采用三种不同的控制方式,使得所述灌溉能够更加符合植物在一天中各个时间段的灌溉需求,从而更有利于植物生长。
进一步的,所述第一辐射阈值为与上一次灌溉经过的时长成正相关的变量,所述第一辐射阈值为Y 1或Y 2,其中,Y 1=200+5/6*X,Y 2=300+5/3*X,X为上一次灌溉时间与第一阶段开启时间之间的差值。本实施方式中,在第一阶段的前半段时间中,第一辐射阈值为Y 1,根据公式Y 1=200+5/6*X计算得出,在第一阶段的后半段时间中,第一辐射阈值为Y 2,根据公式Y 2=300+5/3*X计算得出。随着时间的推移,所述第一辐射阈值越来越大,从而使得灌溉频率越来越小,能够更加符合下午植物蒸腾作用越来越弱、所需的水分越来越少的情景,防止灌溉过多浪费资源。可以理解的是,所述第一辐射阈值也可以为预先设定的辐射量的定值。另外,所述第二辐射阈值为预先设定的辐射量的定值。
本实施方式中,采用滴箭头灌溉,其中每个滴箭头每次的出水量为125ml,每次可以打开所有的滴箭头进行灌溉,也可以按照一定的算法打开部分滴箭头进行灌溉,其中,灌溉液体为营养液,EC(营养液浓度)为3.5mS/cm,PH(氢离子浓度指数)为5.2-5.8。当然,也可以采用其他的灌溉装置,只要能实现自动灌溉即可。
S102:在间歇性灌溉过程中检测第一特征值是否大于或等于预设阈值,若是,停止所述间歇性灌溉。
具体的说,在步骤S102中,在间歇性灌溉过程中,每次灌溉完成后,检测第一特征值是否大于或等于预设阈值,所述第一特征值为排液量与灌溉量之间的比值,当排液量与灌溉量之间的比值大于或等于预设阈值时,表明有较多灌溉液体未被植物吸收,此时则停止间歇性灌溉,防止灌溉过量导致浪费,同时,由于系统是在每次灌溉完成之后检测一次而不是实时读取所述第一特征值,既能保证系统能够较为及时检测到灌溉量是否过大,也在一定程度上减少了系统的用电消耗。
值得一提的是,第一特征值可以是当天截至检测时刻的排水量的总和与当天截至检测的时刻的灌水量的总和之比,也可以是检测时刻前预设时间段内的排水量与灌溉量之比,其中,排液量由排水量传感器测得,灌溉量由灌溉量传感器测得,二者均采用水流量传感器,水流量传感器主要由铜阀体、水流转子组件、稳流组件和霍尔元件组成,首先经过独立机芯的前导流体并加速,流体的动能作用于涡轮的叶片上,由于涡轮叶片与流体流向成一定角度,此时涡轮产生转动力矩,在涡轮克服阻力矩和摩擦力矩后开始,当诸力矩达到平衡时,转速稳定,涡轮转动角速度与流量呈线性关系,通过旋转的发信盘上的磁体周期性地改变传感器磁阻,从而在传感器两端感应出与流体体积流量成正比的脉冲信号,该信号经前置放大器放大、整形后和压力传感器、温度传感器检测到的压力、温度信号同时输出给流量积算仪进行处理,直接显示标准体积流量和标准体积总量。由于本实施方式中,所述第一特征值为排液量与灌溉量之间的比值,通过判断排液量与灌溉量之间的比值是否大于预设阈值(其中,预设阈值可以根据植物的不同种类、季节、当地的环境条件以及当天的天气状况等来进行设定),能够较为准确的判断灌溉是否过量,更有利于合理的灌溉。可以理解的是,所述第一特征值也可以是排水量,该排水量可以是当天截至检测时刻的排水量的总和或检测时刻前预设时间段内的排水量,只要能表征灌溉液体未被植物吸收的程度即可。
可以理解的是,也可以是,在间歇性灌溉过程中,实时检测第一特征值是否大于或等于预设阈值;若是,则立即停止本次灌溉、并停止间歇性灌溉。具体的说,系统实时采集灌溉系统的灌溉量和排水量,并自动计算得出排水量所占的灌溉量的百分比,并判断排水量所占的灌溉量的百分比是否大于或等于预设阈值,当排液量与灌溉量之间的比值大于或等于预设阈值时,表明有较多灌溉液体未被植物吸收,此时则立即停止本次灌溉、并停止间歇性灌溉。由于是实时检测排液量与灌溉量之间的比值是否大于或等于预设阈值,并且在排液量与灌溉量之间的比值大于或等于预设阈值时,立即停止了本次灌溉,因此能最及时的防治灌溉过量,从而最大程度的避免了灌溉过量导致灌溉液体的浪费。
S103:计算所述间歇性灌溉的停止时间与日落时间之间的差值。
具体的说,在步骤S103中,通过计算间歇性灌溉的停止时间与日落时间的差值,当差值较大时,则表明距离日落还有较长时间,在这段时间之内,植物还会进行较多的光合作用,因此还需要进行灌溉。本实施方式中,所述日落时间为前一天的日落时间,由于前一天的日落时间一般较为接近今日的日落时间,因此能够更加准确的预测今日的日落时间,从而能够根据这个时间更加准确的判断失误是否还需要灌溉,从而使得灌溉更加适合植物的实际生长需求,既不会灌溉过多导致烂根,也不会灌溉过少影响植物生长。
S104:当所述差值大于第一预设时长时,则在日落时间之前再启动一次灌溉。
具体的说,在步骤S104中,当间歇性灌溉的停止时间与日落时间的差值大于第一预设时长时,说明距离日落还有较长时间,在这段时间之内,植物还需要较多的营养液,因此在日落之前再启动一次灌溉,该一次灌溉可以是连续的一次灌溉,也可以是间歇性的一次灌溉。其中,第一预设时长可以根据植物的不同种类、季节、当地的环境条件以及当天的天气等因素来进行设定。
本申请实施方式相对于现有技术而言,通过在间歇性灌溉过程中检测排水量和灌溉量之间的比值是否大于或等于预设阈值,当检测排水量和灌溉量之间的比值大于或等于预设阈值时,说明灌溉液体未被植物充分吸收,则停止所述间歇性灌溉,从而避免了灌溉过量,造成资源的浪费;通过计算所述间歇性灌溉的停止时间与前一天的日落时间之间的差值,当所述差值大于第一预设时长时,说明距离今日日落还有较长时间,植物在今日日落之前还是需要灌溉溶液的补充,则在日落时间之前再启动一次灌溉,从而避免了灌溉太少,影响植物生长,从而实现合理灌溉,既保证植物的生长需求,又避免资源浪费。
本申请还涉及一种自动化灌溉控制方法。第二实施方式与第一实施方式大致相同,主要区别之处在于:在本实施方式中,所述启动间歇性灌溉的步骤之后,还包括:在日落时间前第二预设时长时,检测所述间歇性灌溉是否停止,若否,则停止所述间歇性灌溉,所述第二预设时长小于所述第一预设时长;所述若所述差值大于第一预设时长,则在日落时间之前再启动一次灌溉的步骤,具体为:在日落时间前第二预设时长之前,再启动一次灌溉。如此设置,使得在日落时间前第二预设时长之后,不会再对植物进行灌溉,从而减少了在夜间湿度过大导致植物烂根的问题。
本实施方式中的自动化灌溉控制方法,如图2所示,具体包括:
S201:启动间歇性灌溉。
S202:在间歇性灌溉过程中检测第一特征值是否大于或等于预设阈值,若是,停止所述间歇性灌溉。
S203:计算所述间歇性灌溉的停止时间与日落时间之间的差值。
本实施方式中的步骤S201、S202、S203与第一实施方式中的步骤S101、S102、S103大致相同,为了避免重复,此处不再赘述。
S204:当所述差值大于第一预设时长时,则在日落时间前第二预设时长之前,再启动一次灌溉,其中,所述第二预设时长小于所述第一预设时长。
具体的说,在步骤S204中,第二预设时长可以根据植物的不同种类、季节、当地的环境条件以及当天的天气等因素来进行设定,总的来说,该种植物在当前的气候条件下,在日落时间前第二预设时长之后不适宜进行灌溉。本实施方式中,在日落前第一预设时长的时刻,启动一次灌溉。如此设置,最后一次灌溉的时间距离日落时间较长,能够一定程度减少在夜间湿度过大导致植物烂根的问题。
S205:在日落时间前第二预设时长时,检测所述间歇性灌溉是否停止。
具体的说,在步骤S205中,在日落时间前第二预设时长时,通过灌溉装置中的水流量传感器检测灌溉的流量是否为零,从而检测间歇性灌溉是否停止,或者是通过检测系统中表征间歇性灌溉停止的特征值来检测间歇性灌溉是否停止。
S206:若在日落时间前第二预设时长时,所述间歇性灌溉尚未停止,则停止所述间歇性灌溉。
具体的说,在步骤S206中,当检测到在日落时间前第二预设时长时所述间歇性灌溉尚未停止,则停止所述间歇性灌溉,则在日落时间前第二预设时长之后,间歇性灌溉一定会停止,又由于启动的最后一次灌溉时在日落时间前第二预设时长之前,所以在日落时间前第二预设时长之后,不会对植物进行灌溉,因此,能够有效的避免因灌溉过多导致植物在夜间烂根的问题。
本申请还涉及一种自动化灌溉控制方法。第三实施方式与第二实施方式大致相同,主要区别之处在于:在本实施方式中,所述停止所述间歇性灌溉的步骤之前,还包括:发送预警信息以提示工作人员。如此设置,能够在灌溉液体很大程度未被植物吸收时,提醒工作人员前往查看,有利于及时发现并解决问题。
本实施方式中的自动化灌溉控制方法,如图3所示,具体包括:
S301:启动间歇性灌溉。
S302:在间歇性灌溉过程中检测第一特征值是否大于或等于预设阈值,若是,则发送预警信息以提示工作人员、并停止间歇性灌溉。
具体的说,在步骤S302中,当排水量比例大于或等于预设阈值时,有可能是灌溉过量、种植装置破损导致排水量较多或检测装置出现故障等,此时,停止间歇性灌溉,防止了灌溉液体的浪费,同时,发送预警信息提醒工作人员前往查看,工作人员通过排查各种造成排水量过多的原因之后,能够对症下药解决问题,从而实现合理灌溉。例如:灌溉过量则保持间歇性灌溉停止状态;种植装置破损导致排水量较多,则更换或修补好种植设备,防止营养液流失,并重新开启间歇性灌溉给植物进行正常的补给;检测装置出现故障,则更换或修好检测装置,避免误判导致植物供给不足,并重新开启间歇性灌溉给植物进行正常的补给。
S303:计算所述间歇性灌溉的停止时间与日落时间之间的差值。
S304:当所述差值大于第一预设时长时,则在日落时间前第二预设时长之前,再启动一次灌溉,其中,所述第二预设时长小于所述第一预设时长。
S305:在日落时间前第二预设时长时,检测所述间歇性灌溉是否停止。
S306:若在日落时间前第二预设时长时,所述间歇性灌溉尚未停止,则停止所述间歇性灌溉。
本实施方式中的步骤S301、S303、S304、S305、S306与上一实施方式中的步骤S201、S203、S204、S205、S206大致相同,为了避免重复,此处不再赘述。
为了便于理解,下面对本实施方式中自动化灌溉控制方法进行具体的举例说明:
1)首先启动间歇性灌溉,具体如下:
灌溉时间日出后90分钟后开始第一次灌溉,日出时间根据电脑端显示为准,比如早上6:30分日出,则8:00开始第一次灌溉;
第二次灌溉根据情况不同,分为时间灌溉和辐射灌溉两种启动方式,第二次灌溉与第一次灌溉时间最大间隔时间为90分钟,辐射灌溉启动条件为辐射总量累积到200J/cm 2时启动第二次灌溉,若在90分钟内,辐射总量达到200J/cm 2时灌溉启动,若90分钟内辐射总量达不到200J/cm 2,则在达到最大时间90分钟时即9:30分开始第二次灌溉;
13:00之前,辐射总量达到200J/cm 2时灌溉启动,即13:00之前,辐射累积量每达到200J/cm 2会灌溉一次,灌溉后归零重新计算;
13:00-15:00,灌溉与辐射总量之间满足以下的关系式时,则启动一次灌溉,公式如下:Y 1=200+5/6*X1,其中Y 1为辐射累积量,X1为13:00到Y 1对应的时间,单位为分钟,且X1≦120,例如:在13:00-15:00的时间段内,第一灌溉所需要达到的辐射累积量为200J/cm 2,之后,电脑端会根据本次灌溉开启时间计算下一次所要达到的辐射累积量,如13:06开启灌溉此时电脑控制灌溉的辐射累积量会归零,剩余辐射累积量为Y 1=200+5/6*X1即Y 1=200+5/6*6=205J/cm 2,则下一次灌溉开启时间为辐射累积量达到205J/cm 2时;
15:00-16:00,灌溉与辐射总量之间满足以下的关系式时,则启动一次灌溉,公式如下:Y 2=300+5/3*X2,其中Y 2为辐射累积量,X2为13:00到Y 2对应的时间,单位为分钟,且X2≦60,例如:在15:00-16:00的时间段内,第一灌溉所需要达到的辐射累积量为300J/cm 2,之后,电脑端会根据本次灌溉开启时间计算下一次所要达到的辐射累积量,如15:03开启灌溉此时电脑控制灌溉的辐射累积量会归零,剩余辐射累积量为Y 2=300+5/3*X2即Y 2=300+5/3*3=305J/cm 2,则下一次灌溉开启时间为辐射累积量达到305J/cm 2时。
2)在间歇性灌溉过程中,每次灌溉完成后,检测排水量比例是否大于或等于25%,当排水量体积达到25%时,系统发出预警信息以提示工作人员,并停止间歇性灌溉过程;在停止间歇性灌溉过程之后,计算所述间歇性灌溉的停止时间与日落时间之间的差值,当所述差值大于3小时的时候,则在日落前3小时的时刻启动最后一次灌溉,否则不启动。上述间歇性灌溉的灌溉量不易控制,容易造成灌溉量过高导致资源浪费或灌溉量过低导致影响植物生长,且灌溉受天气影响较大,晴天时辐射量较高,灌溉量就较大,此时排出液较多造成资源浪费,通过在间歇性灌溉过程中,检测排水量比例,当排水量体积达到25%时,系统发出预警信息以提示工作人员,并停止间歇性灌溉过程,能够防止灌溉过多,从而节约资源;通过在停止间歇性灌溉过程之后,判断此时是否距离日落还有较长时间,当还有较长时间时,再进行最后一次灌溉,避免了灌溉过少影响植物生长的问题,从而实现了合理灌溉,既保证了植物的生长需求,又避免了资源浪费。值得一提的是,排水量比例设定的阈值小于30%,才能满足节约资源的需求。
3)16:00之后,不再进行灌溉。由于植物在夜间湿度太大会导致烂根的问题,所以,在16:00之后,不再进行灌溉,此时距离日落时间还有一段距离,多余的水分能够被光合作用所消耗,从而一定程度上避免了植物烂根的问题。
上面各种方法的步骤划分,只是为了描述清楚,实现时可以合并为一个步骤或者对某些步骤进行拆分,分解为多个步骤,只要包括相同的逻辑关系,都在本专利的保护范围内;对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计,但不改变其算法和流程的核心设计都在该专利的保护范围内。
本申请还涉及一种多屏终端,如图4所示,包括:至少一个处理器401;以及,与至少一个处理器401通信连接的存储器402;其中,存储器402存储有可被至少一个处理器401执行的指令,指令被至少一个处理器401执行,以使至少一个处理器401能够执行上述推荐用户充值的信息提醒的方法。
其中,存储器402和处理器401采用总线方式连接,总线可以包括任意数量的互联的总线和桥,总线将一个或多个处理器401和存储器402的各种电路连接在一起。总线还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路连接在一起,这些都是本领域所公知的,因此,本文不再对其进行进一步描述。总线接口在总线和收发机之间提供接口。收发机可以是一个元件,也可以是多个元件,比如多个接收器和发送器,提供用于在传输介质上与各种其他装置通信的单元。经处理器401处理的数据通过天线在无线介质上进行传输,进一步,天线还接收数据并将数据传送给处理器401。
处理器401负责管理总线和通常的处理,还可以提供各种功能,包括定时,外围接口,电压调节、电源管理以及其他控制功能。而存储器402可以被用于存储处理器401在执行操作时所使用的数据。
本申请还涉及一种计算机可读存储介质,存储有计算机程序。计算机程序被处理器执行时实现上述方法实施例。
即,本领域技术人员可以理解,实现上述实施例方法中的全部或部分步骤是可以通过程序来指令相关的硬件来完成,该程序存储在一个存储介质中,包括若干指令用以使得一个设备(可以是单片机,芯片等)或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括:U盘、移动硬盘、只读存储器(ROM,Read-Only Memory)、随机存取存储器(RAM,Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
本领域的普通技术人员可以理解,上述各实施方式是实现本申请的具体实施例,而在实际应用中,可以在形式上和细节上对其作各种改变,而不偏离本申请的精神和范围。
