An absorption type multifunctional infrared electronic fence relates to the field of transformer substation maintenance. In detection and maintenance operation projects of electric equipment of a transformer substation, traditionally, a red curtain is hung on a protection screen so as to warn people with no duty to keep away. However, the red curtain fastening process is large in time consumption;the red curtain is easy to slip off and brings inconvenience for tour inspection. The absorption type multifunctional infrared electronic fence includes an infrared emission box provided with an infrared emission device and an infrared reception box provided with an infrared reception device. The infrared emission box and the infrared reception box are each provided with a rectangular absorptionface used for absorption and fixing. Each absorption face is provided with an absorption device. The infrared reception box is provided with a loudspeaker and a microphone. The infrared reception boxis therein provided with a control circuit board. The infrared reception device, the loudspeaker and the microphone are all connected to the control circuit board. Each of the infrared transmission box and the infrared reception box is provided with a cell. By adopting the technical scheme provided by the invention, entering of persons into a dangerous area can be sensed in advance conveniently and a voice prompt and warning effect can be achieved. The absorption type multifunctional infrared electronic fence is good in warning effect, convenient to use and high in safety and reliability.
