具体实施方式
以下结合附图对本发明的实施例进行详细说明，但是本发明可以由下述所限定和覆盖的多种不同方式实施。
如图1所示，本发明的优选实施例提供一种全自动化水质检测实验室，其包括：
样品瓶供给单元1，用于在对待测样品瓶进行水样信息登记后暂存待测样品瓶，并将待测样品瓶输送至传送单元4上；
分析单元2，包括若干个分析模块组，用于对待测样品瓶进行水质检测分析；
样品瓶回收单元3，用于回收已完成检测的样品瓶；
传送单元4，用于将待测样品瓶输送至对应的分析模块组，并将已完成检测的样品瓶输送至所述样品瓶回收单元3；
控制单元，分别与所述样品瓶供给单元1、分析单元2、样品瓶回收单元3和传送单元4连接，用于控制各个单元的工作状态，以实现水样检测全流程自动化控制。
其中，所述样品瓶供给单元1、若干个分析模块组和样品瓶回收单元3间隔设置在所述传送单元4的旁边。所述控制单元用于控制所述样品瓶供给单元1将待测样品瓶输送至所述传送单元4上，然后根据待测样品瓶的水样信息控制所述传送单元4将待测样品瓶输送至对应的分析模块组，即待测样品瓶的待检测水质参数与分析模块组的测试参数信息相匹配，再控制所述传送单元4将已完成检测的样品瓶输送至所述样品瓶回收单元3中进行回收，全程实现检测项目的自动化匹配和自动化输送，无需人为干预，自动化程度高，并且，减少了分析设备轮空的次数，提高了分析设备的利用效率，从而提高了水质检测效率。
其中，所述分析单元2包含的分析模块组的数量、每个分析模块组的类型、每个分析模块组的检测项目等可以根据实际需要进行设定，在此不做具体限定。例如，在本发明的一实施例中，所述分析单元2包括A类分析模块组、B类分析模块组、C类分析模块组和N类分析模块组，其中，A类分析模块组共4套，每一套分别能检测A1、A2、A3、A4、A5等检测项目，B类分析模块组共4套，每一套分别能检测B1、B2、B3、B4、B5等检测项目，C类分析模块组共3套，每一套分别能检测C1、C2、C3、 C4、C5等检测项目，N类分析模块组共3套，每一套分别能检测N1、N2、N3、N4、N5等检测项目。
可以理解，本实施例的全自动化水质检测实验室，在完成待测样品瓶的水样信息登记后，通过所述控制单元控制所述样品瓶供给单元1将待测样品瓶输送至所述传送单元4上，然后根据待测样品瓶的水样信息控制所述传送单元4将待测样品瓶输送至对应的分析模块组，再控制所述传送单元4将已完成检测的样品瓶输送至所述样品瓶回收单元3中进行回收，全程实现检测项目的自动化匹配和自动化输送，无需人为干预，自动化程度高，并且，减少了分析设备轮空的次数，提高了分析设备的利用效率，从而提高了水质检测效率。
其中，在接收水样后对待测样品瓶进行水样信息登记，水样信息包括采样地点、采样时间、采样人员、样品送达时间、待检测的水质参数等。每个待测样品瓶均贴有标识，以使样品瓶获取唯一的身份信息，从而区分不同的样品，在进行水样信息登记时，将每个待测样品瓶的水样信息与其标识关联存储，通过读取样品瓶的标识即可获取该样品瓶的水样信息。若样品瓶来样时没有进行标识，则在水样信息登记时需要对样品瓶进行标识，贴标识的动作可以由人工进行，或者由自动贴标签设备自动进行。
其中，所述样品瓶供给单元1包括待测样品瓶存放区11、运输装置12和第一水样信息读取装置13，所述待测样品瓶存放区11用于暂存已完成登记的待测样品瓶，所述运输装置12则用于将所述待测样品瓶存放区11中存放的待测样品瓶输送至所述传送单元4上，所述第一水样信息读取装置13设置在所述运输装置12的传输路径上，用于通过识别输送的待测样品瓶上的标识读取水样信息。所述运输装置12与所述传送单元4对接的位置处还设置有第一挡瓶装置14，从而在所述第一挡瓶装置14与所述运输装置12的起始位置之间形成新样检测缓冲区，经过第一水样信息读取装置13读取水样信息的多个待测样品瓶在所述新样检测缓冲区内按顺序排列，从而可以知道每个待测样品瓶的位置信息。所述运输装置12、第一水样信息读取装置13和第一挡瓶装置14均与所述控制单元连接，所述控制单元用于将所述第一水样信息读取装置13读取的至少一个样品瓶的水样信息与各个分析模块组的检测项目进行匹配，当第N个(N≥1)待 测样品瓶的水样信息与其中至少一个空闲的分析模块组匹配成功后，所述控制单元控制所述第一挡瓶装置14打开，将N个待测样品瓶输送至所述传送单元4，并控制所述传送单元4将第N个待测样品瓶对应输送至匹配的分析模块组。如此，实现“精准放行”，提高系统的预知性、智能性，优化系统工作效率，降低传送单元的运载负荷。
在首次检测时，所述控制单元控制运输装置12对待测样品瓶存放区11中存放的多个待测样品瓶进行依次输送，多个待测样品瓶依次通过第一水样信息读取装置13，第一水样信息读取装置13依次读取每个待测样品瓶的水样信息，并将其反馈至控制单元，所述控制单元根据每个待测样品瓶的水样信息与分析模块组进行匹配，并打开第一挡瓶装置14，以将新样检测缓冲区中存放的多个待测样品瓶有序地输送至传送单元4的起始端。由于每个分析模块组的位置基本保持固定，而多个待测样品瓶依次排列，则所述控制单元控制所述传送单元4将多个待测样品瓶依次输送匹配的分析模块组处，以进行水质检测分析，实现了待测样品瓶的自动化分配，降低了分析设备的轮空率，提高了分析设备的利用效率。可以理解，当一批待测样品瓶被输送至传送单元4上后，所述控制单元控制第一挡瓶装置14关闭。由于传送单元4上样品瓶的容载量有限，因此需要对输送至传送单元4上的样品瓶数量进行合理控制，即需要保证分析模块组不会出现轮空，使得检测效率最高，且需要保证传送带上的样品瓶不至于出现拥堵。
进一步地，由于分析模块组检测的参数不尽相同，各参数的分析时长也不尽相同，且样品瓶待检测的水样参数不尽相同，因此分析模块组测试完一个样品，再次达到空闲状态的时间点也就不一致，例如，传送单元旁间隔设置有A、B、C、……、N几类分析模块组，A类分析模块组可以检测的参数有A1、A2、A3、A4、A5，B类分析模块组可以检测的参数有B1、B2、B3、B4、B5，C类分析模块组可以检测的参数有C1、C2、C3、C4、C5，N类分析模块组可以检测的参数有N1、N2、N3、N4、N5，A类分析模块组进行A1、A2、A3、A4、A5的分析时长分别是t 1、t 2、t 3、t 4、t 5，B类分析模块组进行B1、B2、B3、B4、B5的分析时长分别是t 6、t 7、t 8、t 9、t 10，C分析模块组进行C1、C2、C3、C4、C5的分析时长分别是t 11、t 12、t 13、t 14、t 15。
当一个样品瓶中样品的待检测参数中，至少一种待检测参数与A分析模块组中测试参数相匹配时，则该样品的分析时长为t 1、t 2、t 3、t 4、t 5分钟中的任一时长。也就是说，当该样品瓶中的样品的待检测的参数为A1时，则该样品的分析时长的t 1分钟，当该样品瓶中的样品的待检测的参数为A1及A2时，则该样品的分析时长为t 1、t 2中时长较大的那个。B、C、……、N类分析模块组亦是如此，不再进行赘述。
当A类分析模块组检测完成后，出现空闲状态时，或者当A类分析模块即将完成检测出现空闲状态时，如果传送单元4上没有与A类分析模块组匹配的样品瓶，则控制单元在新样检测缓冲区匹配与A类分析模块组对应的样品瓶，打开第一挡瓶装置14，将该样品瓶输送至A类分析模块组处，也就是说，当第一挡瓶装置14前第N个样品瓶的待检测的水样参数与A分析模块的测试参数匹配，则控制单元控制第一挡瓶装置14对前N个样品瓶进行放行，第N+1个样品瓶不予放行，以保证第N个样品瓶能输送至A分析模块处，且不会使得传送单元4上的样品瓶数量过高，而影响样品瓶的顺利输送。另外，在本发明的另一实施例中，所述样品瓶供给单元1还包括自动开盖装置，用于对待测样品瓶进行去盖操作，去盖后的样品瓶则等待被输送。其中，所述自动开盖装置可以采用机械手进行去盖操作。
可以理解，所述传送单元4包括环形传送带41、自动挡板42、移瓶装置43和位置检测装置，若干个分析模块组间隔设置在所述环形传送带41旁，每个分析模块组对应的位置处均设置有自动挡板42、移瓶装置43和位置检测装置，所述自动挡板42用于阻拦待测样品瓶在所述环形传送带41上继续输送，所述移瓶装置43则用于将待测样品瓶移动至分析模块组上，或者将取样完成后的样品瓶移动至所述环形传送带41上继续输送。所述自动挡板42、移瓶装置43和位置检测装置均与所述控制单元连接，所述控制单元还用于根据分析模块组的位置信息和所述位置检测装置的位置检测结果控制所述自动挡板42和移瓶装置43的工作状态，以将待测样品瓶推送至对应匹配的分析模块组。具体地，每个分析模块组的位置是预设的，而所述位置检测装置可以检测到待测样品瓶的位置信息，当所述控制单元根据待测样品瓶的位置信息判断出待测样品瓶即将到达与其匹 配的分析模块组的位置时，控制所述自动挡板42动作以拦截该待测样品瓶，然后控制所述移瓶装置43动作以将待测样品瓶移动至匹配的分析模块组，再控制所述自动挡板42动作以解除拦截。所述分析模块组的自动取样装置则从该待测样品瓶中抽取水样进行检测分析，并在完成检测分析后，将分析结果上传至控制单元，所述控制单元则将该分析结果与该待测样品瓶的标识进行关联存储，并控制所述移瓶装置43将该样品瓶移动至环形传送带41上继续输送。可以理解，也可以在每个分析模块组上单独设置一个移瓶装置43，将取样完成后的样品瓶移动至所述环形传送带41上的动作则由分析模块组上的移瓶装置43来实现。例如，如图2所示，在本发明的另一实施例中，传送单元4在每个分析模块组的对应位置处设置有移瓶气缸46和挡瓶气缸47，同时在分析模块组上设置有移瓶气缸46，传送单元4上的移瓶气缸46用于推动样品瓶从环形传送带41上移动至分析模块组上，挡瓶气缸47则用于驱动自动挡板42动作以挡住样品瓶，分析模块组上的移瓶气缸46则用于将取样完成后的样品瓶移动至环形传送带41上。如此，可实现样品瓶的自动精准分配至分析模块组，且样品瓶中的样品不需要进行分装，可以直接配送至分析模块组的检测工位供分析模块组取样检测，避免样品分装影响检测效率和样品可靠性。
其中，所述自动挡板42可以采用气缸或电缸驱动挡板来回伸缩的结构形式，或者采用电机驱动挡板上下转动的结构形式。所述移瓶装置43则可以采用气缸或电缸驱动的方式将样品瓶推动至分析模块组上，或者将样品瓶从分析模块组上拉回至环形传送带41上。所述自动挡板42和移瓶装置43的具体结构设计在此不做具体限定，本领域技术人员可以根据需要进行选择。所述位置检测装置为计数器，每当待测样品瓶经过一个分析模块组时，对应的计数器则计数一次，而多个分析模块组分布的位置顺序是预设的，从而通过计数的方式可以识别出待测样品瓶的位置信息。所述控制单元根据待测样品瓶的水样信息与分析模块组进行匹配后，可以生成待测样品瓶的路径数值，每当待测样品瓶经过一个分析模块组时，对应的计数器对待测样品瓶计数一次，直到累计的计数数值与其路径数值一致时，则意味着待测样品瓶已经移动到了匹配的分析模块组的位置处，然后所述控制单元控制自动挡板42进行拦截，并控制移瓶装置43将待测样品瓶移动至匹配的分析模块组上。当然，在本发明的另一实施例中，所述位 置检测装置也可以采用接近开关，即每当待测样品瓶经过一个分析模块组时，所述控制单元可以接收到一次接近开关的反馈信号，根据所接收的反馈信号的次数即可识别出待测样品瓶的当前位置信息。
另外，所述传送单元4在与所述样品瓶回收单元3对接的位置处设置有自动挡板42、移瓶装置43和第二水样信息读取装置45，所述第二水样信息读取装置45与所述控制单元连接。所述控制单元还用于根据所述第二水样信息读取装置45读取的水样信息识别样品瓶是否已完成水质检测，并根据识别结果控制所述自动挡板42和移瓶装置43的工作状态。若识别出样品瓶已完成水质检测，则所述控制单元控制自动挡板42拦截样品瓶，并控制移瓶装置43将样品瓶移动至样品瓶回收单元3上；若识别出样品瓶未完成水质检测，则所述控制单元不发出控制信号，自动挡板42和移瓶装置43不动作，样品瓶继续在环形传送带41上传送。可以理解，所述第一水样信息读取装置13和/或第二水样信息读取装置45采用RFID读卡器，则样品瓶上的标识为RFID标签；或者所述第一水样信息读取装置13和/或第二水样信息读取装置45采用扫描设备，则样品瓶上的标识为条形码或者二维码。
作为优选的，所述传送单元4还包括设置在所述环形传送带41上的第二挡瓶装置44，所述第二挡瓶装置44位于所述样品瓶供给单元1和所述样品瓶回收单元3之间，用于阻拦初次水样检测后剩余的待测样品瓶在所述环形传送带41上继续输送，以形成二次检测缓冲区，所述第二挡瓶装置44与所述控制单元连接。所述第二挡瓶装置44正常会处于关闭状态，从而将未完成检测的样品瓶拦截在二次检测缓冲区。一方面，此时基本上所有的分析模块组都处于检测过程当中，不存在分析模块组轮空的情况，通过第二挡瓶装置44配合第一挡瓶装置14进行拦截，可以有效的管控环形传送带41上输送的样品瓶的数量。另外，环形传送带41的长度有限，能容纳的样品瓶数量有限，当环形传送带41的容载量达到上限时，所述控制单元控制第一挡瓶装置14和第二挡瓶装置44均不放行，便于进行运输流量管控。另一方面，由于不同的分析模块组检测水质参数的时长不同，会出现部分分析模块组空闲的情况，此时通过第二挡瓶装置44配合第一挡瓶装置14进行拦截，便于根据空闲的分析模块组的检测项目对应地补 充待测样品瓶，提高了分析模块组的利用率，提高了自动化分配的准确率和可靠性。通过“两个检测缓冲区”的设置，结合调度算法实现水样的精准配送，从而减少样品瓶和/或分析模块组轮空，降低传送单元容载和控制单元判断控制的负荷，进而提高系统整体检测效率。
作为优选的，所述样品瓶回收单元3还包括与所述控制单元连接的自动加盖装置，当完成水质检测的样品瓶需要留样保存时，所述控制单元控制所述自动加盖装置对样品瓶进行加盖操作。
另外，在本发明的另一实施例中，所述全自动化水质检测实验室还包括与所述控制单元连接的自动清洗单元。当完成水质检测的样品瓶不需要保存时，样品瓶将被输送至自动清洗单元处进行清洗、干燥处理，以实现样品瓶的循环利用。
可以理解，所述控制单元还用于获取每个分析模块组的工作状态信息，从而可以识别出哪些分析模块组处于检测当中，哪些分析模块组处于轮空当中，并在至少一个分析模块组出现空闲时，根据空闲的分析模块组的检测项目从新样检测缓冲区或者二次检测缓冲区中筛选出匹配的待测样品瓶，并对应控制所述第一挡瓶装置14或第二挡瓶装置44打开。
作为优选的，基于先进先出的原则，所述控制单元优先从所述二次检测缓冲区中筛选匹配的待测样品瓶。
具体地，所述控制单元控制第一挡瓶装置14打开，第一批次的待测样品瓶被送入传送单元4上后，控制第一挡瓶装置14关闭，并控制传送单元4将多个待测样品瓶对应地输送至匹配的分析模块组。此时，若在初次上样检测过程中出现至少一台分析模块组处于空闲状态，则所述控制单元从新样检测缓冲区内筛选出与该空闲的分析模块组相匹配的样品瓶，并控制第一挡瓶装置14打开，直至该匹配的样品瓶被送入传送单元4上。当然，为了保证一开始所有的分析模块组不出现空闲状态，也可以在初次上样时，所述控制单元可以根据所有分析模块组的检测项目控制第一挡瓶装置14持续打开，通过第一水样信息读取装置13读取每个待测样品瓶的水样信息，直至识别出输送至传送单元4上的多个待测样品瓶可以满足每个分析模块组的匹配需求时，所述控制单元控制第一挡瓶装置14关闭。 此时每个分析模块组均处于检测状态，不会出现空闲，多出来的待测样品瓶则被拦截在第二挡瓶装置44处，等待放行。如此，保证样品能实现“先进先出”，即先进入传送单元的样品检测优先级要高于后进入传送单元的样品，从而使得先进入的样品优先完成检测并下线回收。
在初次检测过程中，由于不同的分析模块组检测水质参数的时长不同，有的分析模块组率先完成检测任务，则会出现部分分析模块组空闲的情况。此时，所述控制单元需要从新样检测缓冲区或二次检测缓冲区中筛选出与空闲的分析模块组相匹配的待测样品瓶，然后放行。基于先进先出的检测原则，所述控制单元优先从二次检测缓冲区中进行筛选，若二次检测缓冲区内存在相匹配的待测样品瓶，则控制第二挡瓶装置44打开，直到该待测样品瓶通过第二挡瓶装置44后，控制第二挡瓶装置44关闭。若二次检测缓冲区内不存在相匹配的待测样品瓶，则所述控制单元从新样检测缓冲区内筛选出相匹配的待测样品瓶，并通过第一挡瓶装置14打开，直至该待测样品瓶通过第一挡瓶装置14后，控制第一挡瓶装置14关闭。可以理解，当多个分析模块组均出现空闲情况时，所述控制单元依然优先从二次检测缓冲区内筛选相匹配的待测样品瓶，只要二次检测缓冲区内存在至少一个相匹配的待测样品瓶，则所述控制单元控制第二挡瓶装置44打开，直至二次检测缓冲区内相匹配的待测样品瓶均通过第二挡瓶装置44后，控制第二挡瓶装置44关闭。此时，若仍然有分析模块组存在空闲情况，则所述控制单元将从新样检测缓冲区内筛选出相匹配的待测样品瓶，然后控制第一挡瓶装置14打开，将相匹配的待测样品瓶送入传送单元4上后再控制第一挡瓶装置14关闭。
可以理解，本发明通过获取分析模块组的工作状态和测试参数信息，并识别出每个待测样品瓶的水样信息，一旦分析模块组出现空闲时，基于分析模块组的测试参数信息与待测样品瓶的水样信息进行匹配，可以自动、智能地进行样品瓶的补充输送，提高了自动补样的精准度，提高了分析模块组的利用率。
可以理解，作为一种变形，也可以在每个分析模块组处设置一个水样识别器，例如水样信息读取装置，从而可以读取即将经过每个分析模块组位置处的样品瓶的水样信息。所述水样识别器与控制单元连接，当所述控 制单元判断出所述水样识别器读取到样品瓶中水样的待测参数与所述水样识别器所在的分析模块组相匹配时，所述控制单元控制该分析模块组对应的自动挡板42放下，并控制对应的移瓶装置43将样品瓶移动至该分析模块组上。在本实施方式中，可以选择不设置位置检测装置。
作为优选的，所述全自动化水质检测实验室还包括与所述控制单元连接的报警单元，所述控制单元还用于在新样检测缓冲区和二次检测缓冲区中均未筛选出匹配的待测样品瓶时，控制所述报警单元发出警报。从而提醒工作人员手动从所述待测样品瓶存放区11内挑选出匹配的待测样品瓶并将其放入到环形传送带41上。其中，所述报警单元发出报警提醒的方式包括但不限于声音报警、灯光报警、振动报警、短信报警或者其结合。
作为优选的，所述全自动化水质检测实验室还包括与所述控制单元连接并用于检测样品瓶是否发生倾倒的感应装置，所述控制单元还用于在所述感应装置检测到样品瓶发生倾倒时控制所述报警单元发出警报。工作人员在收到报警提醒后，人工对环形传送带41上倾倒泄露的样品瓶进行清理。其中，所述感应装置可以采用高度检测装置，用于检测样品瓶的高度，所述控制单元可以根据感应装置检测的高度来判断样品瓶是否发生倾倒，一旦样品瓶的高度低于阈值，则意味着样品瓶发生了倾倒。作为另一种选择，所述感应装置也可以采用姿态识别模块，通过搭载的摄像头和图像处理芯片来识别出样品瓶当前的姿态，一旦识别出样品瓶处于横放姿态，则判定样品瓶发生了倾倒，则发出警报。
另外，如图3所示，本发明的另一实施例还提供一种水样的自动化输送方法，优选采用如上所述的全自动化水质检测实验室，具体包括以下内容：

步骤S3：通过传送单元4将待测样品瓶输送至对应的分析模块组，以进行水质检测分析；

可以理解，本实施例的水样的自动化输送方法，在完成待测样品瓶的水样信息登记后，通过所述控制单元控制所述样品瓶供给单元1将待测样品瓶转送至所述传送单元4上，然后根据待测样品瓶的水样信息控制所述传送单元4将待测样品瓶输送至对应的分析模块组，再控制所述传送单元4将已完成检测的样品瓶输送至所述样品瓶回收单元3中进行回收，全程实现检测项目的自动化匹配和自动化输送，无需人为干预，自动化程度高，并且，减少了分析设备轮空的次数，提高了分析设备的利用效率，从而提高了水质检测效率。
