一种冻鱼分拣装置，用于冻鱼品种分类，重量分级，本发明涉及水产品分拣装置技术领域。
背景技术
我国海水养殖业发展规模经济产生大幅增长，而养殖的鱼类进入内陆的时候，就需要将鱼冷冻起来防止鱼类腐败变质、保持其鲜度、营养性，就要尽可能减少鱼暴露在常温下，最大限度地延长鱼的保质期，这就需要减少对冻鱼的加工处理时间，而现有的鱼类称重分选机一般分为三段：
人工入料段：鱼放入自动分选秤的前段称重输送带，在设备运转之前需要将称重机输送带的速度设定，一般根据产品的间距和所要求的速度共同决定的，目的是保证重量分选机工作过程中，只能有单条鱼在设备的称重秤台上进行称重，国内基本上是人工放鱼的方式；
检测称重段：当一条条鱼陆续进入称重段后，大航子站控制系统根据光电信号，快速识别鱼体已经进入称重皮带上，根据称重段运行的速度和输送机的长度，大航子站控制系统可以判定，鱼体离开称重段的时间，从产品进入秤台到离开秤台，称重传感器将检测到信号，控制器选取信号稳定区域的信号进行处理，就可得到产品的重量；
多级分选段：紧接着控制器得到产品的重量信息之后，大航子站控制系统将和预先设定的重量等级范围进行比较，对鱼体进行重量分选，将不同重量大小的鱼分选至不同重量等级的工位分选框内；
这种机型虽然取代了一些人力，但还是离不开人力，需要人力在速度匹配段连续不断的放冻鱼，机型只能按重量分级，不能检测识别出鱼的种类、大小及是否残缺。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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他实施例，都属于本发明保护的范围。
实施例1
如图1-17所示，一种冻鱼分拣装置，包括依次连接的第一级稀散装置1、第二级稀散装置2、第三级稀散装置3、检测识别装置4、多轨道多级分选装置5，所述第一级稀散装置1包括第一传送带12和第二传送带17，所述第一传送带12上设置有入料斗11，第二传送带17上设置有压力传感器和收拢器18；所述第二级稀散装置2包括传送轮组22和横向设置在传送轮组22上方的挡板23；用于将第二传送带17输入的冻鱼逐条送入下一级；所述第三级稀散装置3包括第三传送带31、第三传送带31上的可控门33及第四传送带41前端的压力传感器，用于将冻鱼能够一条一条的进入到检测识别装置4；所述检测识别装置4包括带压力传感器的第四传送带41和带图像处理设备43的第五传送带42，第四传送带41上的压力传感器测得冻鱼的重量范围，第五传送带42上的拍照设备及其图像处理配件测得冻鱼的种类；所述多轨道多级分选装置5包括第六传送带52和多组由步进电机控制的分拣挡板54，所述步进电机接收检测识别装置4的信号，打开对应的分拣挡板54，使冻鱼沿着分拣挡板54进入到与其重量及种类对应的框中，以此来完成分选。
本发明的工作原理为：本发明通过冻鱼稀散装置、检测识别装置4、多轨道多级分选装置5来取代人力，智能自动化生产，具体运行过程如下：
所述冻鱼稀散装置分为第一级稀散装置1、第二级稀散装置2、第三级稀散装置3，所述第一级稀散装置1包括第一传送带12、第二传送带17及其入料斗11，第一级稀散装置1的功能是将从入料斗进入的一大堆冻鱼稀散为几条冻鱼；如图3所示：当机器启动时，第一传送带12和第二传送带17同时运转，第一传送带12将由入料斗倒入的冻鱼传送到第二传送带17上，第二传送带17上设置有压力传感器，当压力传感器上检测到的压力大于设定值时，第一传送带12停止运转，第二传送带17继续转动，将冻鱼向下一级传送，当第二传送带17上的压力小于设定值时，第一传送带12开始运转，如此循环，可将第一传送带12上的一堆冻鱼，经过第二传送带17后，每次只向下一级传送几条冻鱼，实现第一级稀散；
所述第二级稀散装置2包括传送轮组22及其上方的两个挡板23，第二级稀散装置2的 功能是将由第二传送带17输入的几条冻鱼不重叠的、按前后顺序送入下一级；如图6所示：由第二传送带17将几条冻鱼送入传送轮组22，传送轮组22为凹槽状，可让冻鱼由从头到尾或从尾到头的方式穿过传送轮组22，传送带轮组上方的挡板23可防止冻鱼重叠，且挡板23下带有毛刷，可延缓冻鱼通过传送轮组22的速度，由此实现第二级稀散；
所述第三级稀散装置3包括第三传送带31、第三传送带31上的可控门33及第四传送带41前端的压力传感器，第三级稀散装置3的功能是使冻鱼能够一条一条的进入到检测识别段；如图10所示：当机器启动时，第三传送带31开始运转，传送轮组22将冻鱼一条条的送入第三传送带31中，第三传送带31将冻鱼向第四传送带41上运输，当第四传送带41前端的压力传感器检测到压力时，第三传送带31上的可控门关闭且第三传送带31停止运转，由图10可看出，第三传送带31和第四传送带41有个高度差，保证当可控门33关闭时整条冻鱼已经落到第四传送带41上，由此可保证只有一条冻鱼进入到第四传送带41中，由此可实现第三级稀散及称重。
所述检测识别装置4不仅能够按照重量分级，还能够按照冻鱼的种类进行分级，如图14所示：第四传送带41上的压力传感器可测得冻鱼的重量范围，第五传送带42上的拍照设备及其图像处理配件可测得冻鱼的种类，本发明对冻鱼种类的分级运用到图像识别及图像处理技术。
所述图像识别技术是是指对图像进行对象识别，识别各种不同形状的目标和对象的技术，图像识别的发展到目前为止有三个阶段：文字识别、数字图像处理与识别、物体识别，图像识别，就是对图像做出各种处理，经过分析后，最终得出我们所要研究的目标。
所述图像处理是指将图像信号转换成数字信号并利用计算机对其进行处理的过程，图像处理中，输入的是质量低的图像，输出的是改善质量后的图像，常用的图像处理方法有图像增强、复原、编码、压缩等。
该部分主要包括：图像采集/处理、计算机、称重传感、控制器、驱动电机，其中图像处理在计算机上完成。
例：图像采集使用MI-SU120M/C工业相机，搭配AR0134 1/3"(4.86x3.66)图像传感器；分辨率为1280*960；帧率为33FPS；数据接口为USB2.0；快门方式为全局快门，称重选用丽景LASCAUX STM-S型称重传感器(型号：STM)，信号采集处理使用西门子PLCSIMATIC S7-200 CPU226(CN)，驱动电机使用步进电机驱动。
本发明所用方法的步骤：将摄像机安装在第五传送带42上方，俯视第五传送带42，通过拍摄第五传送带42上出现的鱼，记录鱼的图片，摄像机采用CCD/CMOS均可，摄像机连接到计算机，计算机完成图像处理提供图像输出信号，并把图像输出信号同时输入到控 制器，控制器的输出信号连接到步进电机装置，并驱动步进电机上的控制门转动，结合第四传送带41上称重装置得到的重量信号，达到分选不同种类不同重量冻鱼的目的；
图像处理步骤主要包括：图像灰度处理、图像去噪、二值化处理、形态学处理以及分类识别，分类的方法，要使得摄像机中接收鱼的图像并将其存储在图像平面存储器中，通过图像处理确定图像的边界值，以及图像的面积、长度和宽度，确定预定区域的比例(长度和/或宽度)，并根据这些区域的预先开采比例确定鱼的种类；
长宽比(长宽比)、面积比(面积/长度)、尾比(尾宽/长度平方根)、头比(头宽/长度平方根)、鼻角和鱼的对称性由图像边缘位置和计算值确定，如果长宽比大于5.5且面积比小于30.0，结论是存在鳕鱼；当长宽比大于5.5且面积比大于30.0时，确定存在鲶鱼；如果纵横比小于5.5且面积比小于30.0，则确定为红鱼；如果长宽比小于5.5且面积比大于30.0，则得出结论为比目鱼；在上述四种鱼类的分析下，每种鱼都有相应的比值。
所述多轨道多级分选装置5如图16所示：当冻鱼进入到第六传送带52时，根据第四传送带41上压力传感器及第五传送带42上的冻鱼种类识别器所发送给可控门的信号完成分选，进行分选时，某种重量及某种种类的冻鱼所对应的步进电机控制挡板23打开，其他的步进电机控制挡板23关闭，因为第六传送带52总是在带动冻鱼向前运转，当冻鱼遇到挡板23时，就会沿着挡板23进入到与其重量及种类对应的框中，以此来完成分选。
