Metal detector and Camera
这两个相机，您更喜欢哪一款？ Which of these two cameras do you prefer?
实际上，对于不同品牌、不同型号的金属探测器来说，就类似他们之间的区别。In fact, for metal detectors of different brands and models, the difference between them is similar.
We have been engaged in the technical support of metal detectors for about 10 years. We deeply understand the differences between them and help many users to understand the differences more deeply and professionally.
在这个过程中，我们与我们的用户一起合作，很多情况下我们都明显的量化并提高了对金属污染物的风险控制水平。In this process, we work with our users. In many cases, we have clearly quantified and improved the level of risk control of metal contamination.
您也应该知道金属探测器是工厂中极少的CCP设备之一，我们应该更专业的认识并使用它。You should also know that the metal detector is one of the few CCP equipment in the food factory, and we should understanding and use it more professionally.
特别是当您拥有一台专业的金属探测器时，你不应该仅把它当作一个傻瓜相机使用。Especially when you own a professional metal detector, you should not just use it as a Point-and-shoot camera.
如果是一名专业摄影师，一定会关注ISO、曝光时间等参数。If you are a professional photographer, you will definitely pay attention to parameters such as ISO and exposure time.
而金属探测器其实情况类似！The situation with metal detectors is similar!
几乎所有的金属探测器都有自动学习功能（傻瓜相机模式），但是我们一直说这只是一个辅助方法。Almost all metal detectors have an automatic learning function( Point-and-shoot camera mode ), but we have always said that this is just an auxiliary method.
即使作为专业人员，对于有产品效应的产品我们仍然需要借助自动学习的帮助。Even as professionals, we still need the help of automatic learning for products with product effects.
但是这里的区别是，作为专业人员有能力判定自动学习的结果是否可以满足实际生产和风险控制的要求。But the difference here is that as professionals, they have the ability to determine whether the result of automatic learning can meet the requirements of actual production and risk control.
比如最典型的情况是，自动学习功能学习的是金属探测器检测到的任何信号。For example, the most typical situation is that the automatic learning function learns any signal detected by the metal detector.
这里的任何信号包括各种干扰信号，除非这个干扰信号金属探测器本身无法检测到。Any signal here includes various interference signals, unless this interference signal cannot be detected by the metal detector itself.
因此，在这种情况下作为普通用户，您确认可以全部识别吗？So in this case, as an ordinary user, can you confirm that you can recognize them all?
根据我们的经验，只有很少的人有能力快速识别这类干扰。According to our experience, only a few people have the ability to quickly identify this type of interference.
所以，我们一直向我们的用户强调，不要擅自学习，请相信你的专业金属探测器，并请相信您的产品工艺本身。Therefore, we have always emphasized to our users, do not learn without authorization, please trust your professional metal detector, and please trust your product process itself.
当然，这里的前提条件是已经确认了金属探测器的各种参数。Of course, the prerequisite here is that the various parameters of the metal detector have been confirmed.
事实上我们的一些用户已经完全禁止擅自更改参数。In fact, some of our users have completely forbidden to change parameters without authorization.
所以，对于专业金属探测器设备均有不同等级的访问权限控制。Therefore, there are different levels of access control for professional metal detector equipment.
我们最近支持的一个用户就采取了三步措施：A user we recently supported took three measures:
1，指定1-2人专职负责金属探测器，因为这是专业设备不可能每人都能熟练掌握。Designate 1-2 people to be in charge of metal detectors full-time, because this is professional equipment and it is impossible for everyone to proficient it.
当然也包括启用访问密码。Of course it also includes enabling the access password.
2，确认参数，不可擅自学习。Confirm the parameters, do not learn without authorization.
3，记录产品和标准测试片的信号值，为进一步控制风险并确认阈值提供数据依据。Record the signal value of the product and the standard test piece to provide a data basis for further controlling the risk and confirming the threshold.
作为改善工作的第一步，我们首先确认了控制产品误检的阈值线。As the first step of the improvement work, we first confirmed the threshold line of product false detection.
根据现场数据（注意，这些数据依赖不同的参数设定，所以金属探测器的参数不可擅自更改，这是确认金属探测器正确设定后的进一步工作）的分析结果，如果将这台设备的阈值设定在大约665，在这种情况下正常产品的误检率应该可以控制在大约千分之一水平。According to the analysis results of field data (note that these data depend on different parameter settings, so the parameters of the metal detector cannot be changed without authorization, this is a further work after confirming the correct setting of the metal detector), if the threshold of this MD is set at approximately 665, in this case the false detection rate of normal products should be able to controlled at about one-thousandth.
利用同样的方法，我们可以进一步评估在上述这种情况下的标准金属测试片的可靠检出率。Using the similar method, we can further evaluate the reliable detection rate of the standard metal test piece in the above-mentioned situation.
我们当前正在与用户确认并验证这个巨大改善。We are currently confirming and verifying the great improvements with users.
最后，我们推荐LOMA品牌金属探测器，这是这个领域中屈指可数的几个专业设备之一，我们对他相当有信心！Finally, we recommend the LOMA brand metal detector, which is one of the few professional equipment in this field. We are quite confident in him!
