Problems solved by technology

[0003] However, the interference of the existing AC power supply is relatively large, and the internal circuit will generate a magnetic field, which will affect the accuracy of the calculation. The distance range of the adjustment device is small, and the light wave distance is too short when performing photoelectric measurement on objects at a slightly longer distance. , the types of light waves accepted by the receiving device are too messy, resulting in a large load on the processor and inaccurate calculation values

Abstract

The invention discloses a photoelectric detection anti-jamming device, which comprises a device body and a power switch. On the body, a touch panel is arranged on the top of the device body, and the touch panel is embedded on the device body. This kind of photoelectric detection and anti-jamming device has an optocoupler inside, and the optocoupler is fixedly connected to the device body, and the optocoupler is electrically connected to the power switch through a wire, and the optocoupler converts the input electrical signal into an optical signal Pass it to the photosensitive tube and convert it into an electrical signal output. Since there is no direct electrical connection, the power supply will not generate a magnetic field. In contrast, the signal is transmitted and at the same time it has the effect of isolating interference.

Description

technical field [0001] The invention relates to the technical field of anti-jamming devices, in particular to a photoelectric detection anti-jamming device. Background technique [0002] The so-called photoelectric detection device refers to the detection device that uses the property of photoelectric elements to change the electrical parameters caused by changes in illumination, and converts optical signals into electrical signals. It is a sensor that uses photoelectric elements as detection elements. It first converts the measured changes into changes in optical signals, and then further converts the optical signals into electrical signals with the help of photoelectric elements. A photoelectric sensor generally consists of three parts: a light source, an optical path, and a photoelectric element. [0003] However, the interference of the existing AC power supply is relatively large, and the internal circuit will generate a magnetic field, which will affect the accuracy o...
