We all know that the metal detector uses the electromagnetic induction principle to detect the metal, but most of us don't know which type the detection signal belongs to. The signal is divided into two types: analog signal and digital signal. Today, we will analyze it from a professional perspective:
In China, the metal detection industry has also experienced several decades of development. In the early stage, it was limited by the production technology at that time. The first generation of products used analog signals for detection, transmission and analysis. Just like the early mobile phone signals, this kind of old-fashioned equipment was able to test its performance at the beginning of its use, but there was an obvious defect, that is, its service life was not long, and it was not long After 2-3 years of use, the detection performance will be greatly reduced, because the signal phase offset of this product will be weakened after a long time of use, so it will slowly exit the market later.
In order to supplement the defect of analog signal, the medium-term development of metal detector equipment adopts the combination of analog signal and digital signal, uses large-scale integrated circuit, completes the collection of analog signal by CPU and converts it into digital quantity for processing, outputs and automatically searches for the best point of metal content of the detected object, and displays it through the LCD screen, to some extent It has greatly improved the reliability and intelligence of the product. At present, there are many applications of this product in the market, because there are certain advantages in price and relatively long service life.
With the rapid development of China's economy, the all-round digital intelligent metal detector has come out. The latest intelligent machine adopts the current advanced metal detection technology, and uses high-speed signal processing technology, photoelectric integration technology, high-speed signal filtering technology, automatic phase adjustment technology, self balancing technology, multi frequency application technology, etc. metal detection has higher sensitivity and better stability, It has a longer service life and can be widely used in various industries. It is also the most widely used in the market at present. It is predicted that in a short time, the full digital metal detector will be fully used in the market, and the metal detection industry will also be fully digital transformation.
Suzhou aoteng Electronic Technology Co., Ltd. is a professional metal detector manufacturer in Jiangsu Province. At present, all our products have entered the digital intelligent stage, which can meet the development needs of the market economy in an all-round way. We are the leading enterprise in the domestic intelligent metal detector industry. Many intelligent technologies independently researched and developed rank the first place.
