Safety switch with infrared image palmprint

Abstract

The invention discloses a safety switch with infrared image palmprint. The safety switch comprises a safety switch front shell, wherein a safety switch rear shell base is arranged on one side of the safety switch front shell, a safety switch wall hanging plate is arranged on one side of the safety switch rear shell base, operation buttons are arranged on a surface of the safety switch front shell,a card reader is arranged at bottoms of the operation buttons, and a display screen is arranged on a surface of the safety switch front shell. The infrared image palmprint safety switch is advantagedin that various intelligent electric appliances or devices in a room can be prevented from being used after non-living body replacement verification such as photos succeeds, so use loss of the intelligent electric appliances is avoided, and infrared image palmprint or palmprint verification has the non-contact characteristic and is clean and sanitary.

Description

technical field [0001] The invention belongs to the technical field of safety switches, in particular to a safety switch with infrared image palm prints. Background technique [0002] A safety switch is a switch that prevents people from entering a hazardous area until all safety conditions are met, and includes a variety of types, including latch switches, safety magnetic switches, safety door lock switches, safety pull rope switches, emergency stop buttons, hinge interlock switches , safety enable switch, safety limit switch, explosion-proof switch, etc., the intelligent safety switch has an original one-to-one protection function for line terminals, integrates current overload protection technology into ordinary switches and sockets, and has temperature rise sensing, automatic power off, and alarm , reset, transfer, connection and other functions. It not only prolongs the service life of the power supply line, but also prevents the occurrence of electrical fires. At the ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a safety switch with infrared image palmprint, to solve the problem that the existing image recognition switch proposed in the above-mentioned background technology is not rigorous enough in use. The photo is verified against the image recognition switch, and you can enter the room, which is unsafe; and there is no cushioning measure between the back shell of the safety switch and the PCB board, once the safety switch is hit, the back shell of the safety switch will directly contact the PCB. The board is squeezed, which greatly reduces the service life of the PCB board. For this reason, we propose a safety switch with infrared image palmprint
