Pepperl+Fuchs talks about the application of sensors in the protection of the Diaoyu Islands

P+F Pepperl+Fuchs photoelectric sensor is a sensor that uses photoelectric elements as detection elements. It first converts the measured change into a change in an optical signal, and then further converts the optical signal into an electrical signal with the help of photoelectric elements. The photoelectric sensor is generally composed of three parts: a light source, an optical path, and a photoelectric element. The photoelectric detection method has high precision and fast response. In addition to the application of industrial sensors, they are gradually being used in technology and border defense measurement and control. For example, the Chinese MA60 MPA maritime patrol aircraft used for maritime surveillance missions in the waters of the Diaoyu Islands uses photoelectric sensors with powerful sensing functions.

The P+F Pepperl+Fuchs photoelectric sensor used in the industrial field realizes control by converting the change of light intensity into the change of electrical signal. In general, the photoelectric sensor is composed of three parts, which are divided into: transmitter, receiver and detection circuit. The transmitter is aimed at the target to emit a light beam, and the emitted light beam generally comes from a semiconductor light source, a light emitting diode (LED), a laser diode, and an infrared emitting diode. The beam is emitted continuously, or the pulse width is changed. The receiver is composed of a photodiode, a phototransistor, and a photocell. In front of the receiver, optical components such as lens and aperture are installed. Behind it is the detection circuit, which can filter out the effective signal and apply the signal. Because the photoelectric switch is small, convenient and sensitive, many industrial control friends love it. Used in the field of technology and border defense monitoring, China Marine Surveillance has long been equipped with large-scale patrol boats transformed from retired warships, and new patrol aircraft will soon be added. This means that China's maritime law enforcement agencies have already begun to simultaneously strengthen the front-line sea and air defense forces. In the future, even if Japan sends a larger tonnage patrol ship or a new amphibious aircraft, China will also have the ability and means to countermeasures equally, and it will give the Chinese people more confidence!
