机顶盒老化装置、机顶盒测试分拣方法、终端及存储介质
本公开要求享有2018年12月29日提交的名称为“机顶盒老化装置、机顶盒测试分拣方法、终端及存储介质”的中国专利申请CN201811641483.8的优先权，其全部内容通过引用并入本文中。
技术领域
本公开涉及机顶盒技术领域，尤其涉及一种机顶盒老化装置、机顶盒测试分拣方法、终端及存储介质。
背景技术
机顶盒又称数字视频变换盒(Set Top Box，STB)，是一个连接电视机与外部信号源的设备。
当前，机顶盒产品生产量较大、产品本身价格较低，机顶盒生产制造企业对机顶盒的生产效率、人力成本有较高的要求。为了提高生产效率，机顶盒在生产过程中，有些工序需要批量进行。如机顶盒的高温老化测试，为提高效率，一般要几百甚至几千台一起作业；传统人工生产线，批量机顶盒一般采用高温自检方式，由人工上下料；高温老化测试过程中人工定时进行巡检，对不良品提前清理及替换；在高温老化测试后，需要根据高温老化测试的成功与否对机顶盒进行分拣。传统生产线的分拣方法是，测试完成后，根据高温老化测试结果进行提示，一般通过特定指示灯状态(如良品亮绿灯、不良品亮红灯)进行提示，机器人根据指示灯状态，对良品、不良品进行挑选。但这种分拣方法效率较低，且由于要对批量机顶盒进行分拣，需要的机器人视觉系统非常多；机顶盒产品形态多样，指示灯颜色、位置不同，机器人视觉系统检测开发难度较高；机顶盒产品更新换代较快，需要投入视觉开发投入较大；受机器视觉技术本身限制检测成功率无法达到100％。

具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
本公开实施例的主要解决方案是：通过主控单元控制输送单元将各个测前机顶盒输送至测试架进行测试；主控单元基于机架状态指示单元从托盘状态指示单元获取托盘状态指示单元确定的各个测后机顶盒的测试结果；当测后机顶盒测试时长达到预设时长后，主控单元根据所述测试结果，控制输送单元对所述测后机顶盒进行良品与不良品分拣、并输送至下料单元。
由于现有技术中，传统人工生产线，批量机顶盒一般采用高温自检方式，由人工上下料，高温老化测试良品与不良品的指示，通过被测机顶盒特定指示灯状态进行提示；高温老化测试过程中人工定时进行巡检，对不良品提前清理及替换，高温老化测试完成后，人工根据指示灯状态对良品、不良品进行挑选。人工需要长时间在高温中工作，劳动强度也很大。而在采用机器人上下料，对测试中的机顶盒状态巡检及测试完成的批量机顶盒进行分拣，常规做法是用机器视觉判断机顶盒指示灯状态，然后机器人进行相应的分拣。由于要对批量机顶盒进行分拣，需要的机器视觉系统非常多、且是串行分拣，效率较低；机顶盒产品形态多样，指示灯颜色、位置不同机器视觉系统检测开发难度较高；机顶盒产品更新换代较快，需要投入视觉开发投入较大；受机器视觉技术本身限制 检测成功率无法达到100％；高温老化测试温度较高，超过或者接近机器视觉系统的工业相机工作温度上限，影响工业相机寿命。
本公开提供一种解决方案，不需要人工进入高温测试区域进行上料测试，改善了工人的工作环境；相对于常规机器视觉系统来说，状态指示方法实现方法简单、开发难度低、成本低，极大地降低了机顶盒的生产成本，节省了大量的测试工序成本，且提高了分拣准确率。
为了提高机顶盒在生产工序中机顶盒高温老化测试的效率，提出一种机顶盒老化装置。为了更好理解本公开，在此提供一种机顶盒老化装置，参照图1和图2，机顶盒老化装置包括主控单元100、测试架200、输送单元300、上料单元400和下料单元500，主控单元100分别与测试架200、输送单元300和分拣机通信连接；测试架200和输送单元300设置在外部设置的高温柜内。测试架200包括机架状态指示单元210，以及两两配对且通信连接的托盘220和托盘状态指示单元230，托盘状态指示单元230均与机架状态指示单元210通信连接；输送单元300用于将测前机顶盒从上料单元400输送至测试架200，以及对测后机顶盒进行分拣并输送至下料单元500；上料单元400用于将测前机顶盒放置输送单元300；下料单元500用于放置输送单元300输送的分拣后的测后机顶盒；托盘状态指示单元230用于将测后机顶盒的测试结果发送至机架状态指示单元210；机架状态指示单元210用于接收托盘状态指示单元230发送的测试结果，并将测试结果发送至主控单元100；主控单元100用于根据测试结果，控制输送单元将测前机顶盒输送至测试架、以及将测后机顶盒进行分拣输送至下料单元。
参照图2和图3，托盘220用于放置各个测中机顶盒，各个测中机顶盒的音频接口分别与托盘220的各个输入接口连接，托盘220的输出接口与配对的托盘状态指示单元230的输入接口连接；测中机顶盒用于在测中机顶盒自测程序执行结束后，通过音频接口将与测试结果对应的音频信号输入至托盘状态指示单元230。
参照图4，托盘状态指示单元230还包括信号调理单元231、信号检测单元232、通讯单元233、在位指示单元234和托盘编号配置单元235，信号调理单元231、信号检测单元232、通讯单元233依次通信连接，托盘编号配置单元235与信号检测单元232通信连接，托盘220、通讯单元233均与在位指示单元234通信连接，通讯单元233与机架状态指示单 元210通信连接；信号调理单元231用于将配对机顶盒发送音频信号进行波形调理，得到含配对机顶盒自测结果的波形信号；信号检测单元232用于根据波形信号，确定配对机顶盒的测试结果；通讯单元233用于将测试结果发送至机架状态指示单元210；在位指示单元234用于检测托盘220与测试架200的连接状态，基于连接状态确定托盘210是否在测试架200上，得到托盘210的在位状态并发送至通讯单元233；托盘编号配置单元235用于为托盘220配置地址码。
参照图5，机架状态指示单元210还包括下行通讯单元211、存储单元212、上行通讯单元213和机架编号配置单元214，下行通讯单元211、存储单元212、上行通讯单元213依次通信连接，机架编号配置单元214与存储单元212通信连接，下行通讯单元211与通讯单元233连接，上行通讯单元213与主控单元100连接；下行通讯单元211用于接收通讯单元233发送的测试结果；存储单元212用于缓存测试结果；上行通讯单元213用于将测试结果上报至主控单元100；机架编号配置单元214用于为测试架配置地址码。
基于上述硬件结构，提出本公开方法实施例。
参照图6，在本公开机顶盒测试分拣方法第一实施例中，机顶盒测试分拣方法包括：
步骤S10，主控单元控制输送单元将各个测前机顶盒输送至测试架进行测试；
在机顶盒生产的高温老化测试工序中，机顶盒需要放置高温环境，本公开实施例采用将机顶盒放置于高温柜中。机顶盒产品在高温环境下进行长时间(如12小时)循环自检测试，自检程序存储于被测机顶盒中、自检程序中包含一个或多个测试用例，自检程序由被测机顶盒独立执行，被测机顶盒执行各测试用例。参照图7，机顶盒的自检程序流程如图7所示，机顶盒初始化后，开始执行测试用例n，测试用例n执行测试后则执行记录测试结果，判断本次测试是否通过。机顶盒测试通过则保持从音频接口输出单音信号(如1K Hz单音)，测试不通过则挂起并停止输送单音信号；或者机顶盒测试不通过则保持从音频接口输出单音信号(如1K Hz单音)，测试通过则挂起并停止输送单音信号。测试通过后，判断该次测试后是否达到测试循环次数，如果该次测试后达到测试循环次数，则机顶盒结束执行自检程序；如果该次测试后没有达到测试循环次数，则在继续执行测试用例n+1。
在这里，输出单音信号，主要是用于分辨机顶盒执行测试用例后的测试结果，所以输出单音信号的可以只在机顶盒测试通过时输出或者只在测试不通过时输出。其中，本 实施例采用单音信号主要是基于机顶盒的结构本身考虑的，选用单音信号的主要原因是，输出单音信号使得整个高温老化测试的处理过程更简单；当然也可以选用输出其他音频信号，但是整个处理过程会变得复杂。
参照图1和图2，高温柜中可以同时放置一个或多个测试架，一个测试架上可以有一个或多个托盘，一个托盘上有一个或多个机顶盒，机顶盒在高温柜中进行高温老化测试。被测机顶盒在前工序事先已安装到托盘内，等待在上料单元上；在主控单元的控制下，输送单元自动抓取托盘运送到空置的测试架上，托盘上的电源、音频接口与测试架相应的接口自动对接；托盘内的机顶盒开始上电并执行自检程序。其中，测前机顶盒，是指已安装到托盘内，等待在上料单元上的机顶盒。
步骤S20，主控单元基于机架状态指示单元从托盘状态指示单元获取托盘状态指示单元确定的各个测后机顶盒的测试结果；
在主控单元的控制下，托盘内的机顶盒开始执行自检程序后，相应的机架状态指示单元通过托盘状态指示单元开始检测机顶盒的测试结果状态，并反馈给主控单元。测试架主要包括机架状态指示单元、托盘状态指示单元和托盘，每个测试架对应一个机架状态指示单元，每个托盘对应一个托盘状态指示单元。托盘状态指示单元用来收集托盘内各个机顶盒的测试结果，并将测试结果反馈给机架状态指示单元，机架状态指示单元将测试结果反馈给主控单元。每个机架、每个托盘都有地址码，主控单元通过数据通讯来定位到每个托盘，而每个托盘内机顶盒的也有位置地址，这样就可以定位到每一台机顶盒。
在一实施方式中，参照图3和图4，机架状态指示单元包括下行通讯单元、存储单元和上行通讯单元；步骤S20包括：
步骤S21，主控单元向机架状态指示单元发送获取测后机顶盒的测试结果的获取指令；
主控单元向机架状态指示单元发送获取测后机顶盒的测试结果的获取指令。其中，测后机顶盒是指，每次循环执行完一次测试用例后的机顶盒。
步骤S22，主控单元接收上行通讯单元基于获取指令，从存储单元中获取并反馈的下行通讯单元接收托盘状态指示单元确定的测后机顶盒的测试结果。
托盘内的各个测后机顶盒在执行自检程序的一个测试用例后，会根据不同的测试结果发出音频信号至托盘状态指示单元，托盘状态指示单元机测后顶盒发出的音频信号确定机顶盒的测试结果并发送至下行通讯单元；下行通讯单元接收到机顶盒的测试结果后 缓存至存储单元；上行通讯单元接收到主控单元发送的、获取测后机顶盒的测试结果的获取指令后，从存储单元中获取机顶盒的测试结果，将机顶盒的测试结果经过总线上报至主控单元；主控单元接收上行通讯单元上报的数据，在一实施方式中，主控单元可以进行数据展示，如通过屏幕显示各个机顶盒的测试状态。主控单元还可以将测试结果数据上传数据库或云端服务器，从而实现工序管控。
在本实施例中，通过托盘状态指示单元确定被测机顶盒的测试结果，托盘状态指示单元将机顶盒的测试结果上报至机架状态指示单元，机架状态指示单元将机顶盒的测试结果上报至主控单元，状态指示单元信息分级上报，通过缓存架构大大缓解主控单元的处理压力，降低主控单元硬件配置要求；相对于常规机器视觉系统来说，状态指示方法实现方法简单、开发难度低、成本低，极大地降低了机顶盒的生产成本；通过分级信息上报，实现可以对批量机顶盒进行检测，指示效率高，极大地提高了机顶盒的生产效率。
步骤S30，当测后机顶盒测试时长达到预设时长后，主控单元根据测试结果，控制输送单元对测后机顶盒进行良品与不良品分拣、并输送至下料单元。
当测后机顶盒的测试时长到达后预设时长后，主控单元通过机架状态指示单元得到托盘的机顶盒的测试结果后，主控单元将完成测试托盘的测试信息及地址码反馈给输送单元，输送单元对测后机顶盒进行良品与不良品分拣、把完成测试的测后机顶盒对应托盘从测试机架取下，并送至下料单元，进而输送到下个工序。主控单元完成整个高温老化测试中的上下料调度、测试结果的收集展示，并将测试信息上传至云端数据库。其中，预设时长可以根据具体需求设置，本公开实施例对预设时长的数值不作具体限定。
在本实施例中，通过主控单元基于机架状态指示单元从托盘状态指示单元获取测试结果，控制输送单元自行上下料至测试架进行高温老化测试、对测后机顶盒进行分拣，实现了机顶盒高温老化测试自动化测试，输送单元自动化上下料、良品分拣；相对于传统人工机顶盒高温老化测试方式，可以节约大量人力成本；实现了测试结果的自动实时监控，无须人工巡检，工人无需进入高温环境作业，改善了工人工作环境；避免采用机器人视觉系统进行分拣，降低了检测开发难度，节省了大量的生产投入成本。
在一实施方式中，步骤S20之后还包括：
步骤S40，主控单元根据测试结果，获取托盘状态指示单元配对托盘内的测后机顶盒的不良品数量；
当某个托盘内某台机顶盒测试不通过，则其语音口停止送出单音信号，测试不通过 的机顶盒对应的托盘状态指示单元，将机顶盒的状态上报到对应的机架状态指示单元，进而机架状态指示单元上报给管理主控单元；主控单元可以监控到各个测试架的托盘数量、各个托盘内的机顶盒数量、以及各个机顶盒的测试状态；在一实施方式中，主控单元将接收到的数据进行展示，人工可以看到主控单元展示的各个机顶盒的状态。
步骤S50，当不良品数量达到预设阈值时，主控单元控制输送单元输出配对托盘内的不良机顶盒至下料单元。
当某个托盘内的机顶盒不良品数量达到预设阈值时，即当同一个托盘内测试不通过的机顶盒数量达到阈值，主控单元则将相关的地址信息发送给输送单元，由输送单元根据相关的地址信息，将对应的托盘取到下料区；可以人工看到主控单元展示的机顶盒的状态，然后根据主控单元展示的机顶盒的状态，对托盘内的不良品机顶盒取下，并更换新机顶盒上去后，送回测试架进行高温老化测试。
在本实施例中，当同一个托盘内的不良机顶盒数量达到预设阈值时，将托盘中的机顶盒取下并更换待测机顶盒，避免了测试后已知不良的机顶盒保持在测试架上继续测试，占用测试架进行无效测试而浪费资源；提高了测试效率。
在一实施方式中，基于图6所示的实施例，在本公开机顶盒测试分拣方法第二实施例中，托盘状态指示单元包括信号调理单元、信号检测单元和通讯单元；盘状态指示单元确定测后机顶盒的测试结果的步骤包括：
步骤A1，托盘状态指示单元获取配对托盘内的各个测后机顶盒基于自测结果发出的音频信号；
机顶盒测试通过则保持从音频接口输出音频信号，测试不通过则挂起并停止输送音频信号，输出的音频信号通过配对托盘(即与机顶盒对应连接的托盘)传输到托盘状态指示单元的信号调理单元。托盘状态指示单元获取测后机顶盒发出的音频信号。被测机顶盒执行各测试用例，机顶盒测试通过则保持从音频接口输出单音信号(如1K Hz单音)，测试不通过则挂起并停止输送单音信号，输出的单音信号通过配对托盘(即与机顶盒对应连接的托盘)传输到托盘状态指示单元的信号调理单元。托盘状态指示单元获取测后机顶盒发出的单音信号。
步骤A2，信号调理单元对音频信号进行波形调理，得到含配对托盘内各个测后机顶盒自测结果的波形信号；
信号调理单元对输入的音频信号进行波形调理，如电平放大、滤波等，使得机顶盒 测试通过与不通过输出的音频信号通过波形调理后，转换为可以明显指示出机顶盒为测试通过或测试不通过的波形信号，进而信号检测单元可以明确识别。
步骤A3，信号检测单元检测波形信号，确定测后机顶盒为良品或不良品，得到测后机顶盒的测试结果。
波形信号传输到到信号检测单元后，信号检测单元对波形信号进行检测，转换成IO状态信号(如1代码有音频信号，0代表无音频信号)，然后信号检测单元将IO状态信号送给通讯单元。本实施例中，采用机顶盒测试通过则保持输出音频信号，测试不通过则停止输出音频信号，信号检测单元对波形信号进行检测，转换成IO状态信号，即检测出了机顶盒有无音频信号输出，进而确定了机顶盒为良品或不良品，得到测后机顶盒的测试结果。
通讯单元将IO状态信号经由总线上报到机架状态指示单元，经过机架状态指示单元的存储单元对数据进行缓存处理，再经由机架状态指示单元的上行通讯单元，经总线送到高温老化测试管理的主控单元内，主控单元进行数据展示。
在本实施例中，机顶盒测试后通过输出音频信号对机顶盒的测试结果进行指示；托盘状态指示单元根据音频信号确定机顶盒的测试结果，通过IO状态信号对机顶盒的测试结果进行状态指示，并上报至机架状态指示单元，经由机架状态指示单元上报至主控单元；状态检测可靠性较高，该指示方法误判率趋近零，而机器视觉系统一般有千分之一以上的误判，避免了采用机器视觉系统进行判断带来的检测误差，提高了检测准确率，进而提高了生产质量。
此外，本公开实施例还提出一种存储介质，所述存储介质上存储有机顶盒测试分拣程序，所述机顶盒测试分拣程序被主控单元执行时实现如上所述的机顶盒测试分拣方法的步骤。
本公开存储介质具体实施方式可以参照上述机顶盒测试分拣方法各实施例，在此不再赘述。
