| 世界上第一台金属探测器诞生于1931年由费舍尔博士在美国发明，被命名为M-Scope但在当时有人早在1924年就制造了金属探测器的雏形，并且于1927年制造出改进型，并认为除非费舍尔能拿出自己更早制造出金属探测器的证据，否则金属探测器之父这一荣誉应属于他。但由于费舍尔申请专利在先，且将金属探测器推向市场，社会各界仍然公认费舍尔博士为金属探测器之父。 The world's first metal detector was invented by Dr. Fisher in the United States in 1931. It was named M-Scope. At that time, some people made the prototype of the metal detector as early as 1924, and in 1927 they made an improved one. They believed that unless Fisher could show evidence that he had made the metal detector earlier. The honor of the father of metal detectors belongs to him. However, because Fisher applied for a patent first, and put metal detectors into the market, the community still recognized Dr. Fisher as the father of metal detectors. 现在我们经常在各种场合都会见到它的身影 Now we often see it on various occasions. 通常的金属检测器主要由两部分组成即检测线圈与自动剔除装置，其中检测线圈为核心部分。 Normally, metal detectors are mainly composed of two parts: detection coil and automatic removal device, in which detection coil is the core part. 线圈通电后会产生磁场，有金属进入磁场，就是引起磁场变化，由此判断有金属杂质某些产品本身含水、盐等到点成分，也会对磁场产生类似金属的干扰。这种现象，称为产品效应。可以通过产品效应补偿功能解决此类问题 Coil electrification will produce magnetic field, metal into the magnetic field, that is to cause magnetic field changes, thus judging that some products with metal impurities, such as water, salt and other components, will also produce metal-like interference to the magnetic field. This phenomenon is called product effect. This kind of problem can be solved by product effect compensation function. 检测到金属之后，传感器启动信号，驱动自动剔除装置，例如翻板，推杆等，将杂质剔除。 After the metal is detected, the sensor starts the signal and drives the automatic eliminating device, such as turning plate, push rod, etc., to remove impurities. 具体说是涡流，探测器产生周期性变化的磁场，周期性变化的磁场在空间产生涡旋电场。而涡旋电场如果遇到金属的话，会形成涡电流，可以被检测到。然后就是滴滴滴的叫个不停了！ Specifically, eddy current, the detector produces a periodically changing magnetic field, the periodically changing magnetic field produces a eddy electric field in space. If the eddy electric field encounters metal, it will form eddy current, which can be detected. And then there's the constant screaming! |
