Abstract

The invention relates to the technical field of Internet of Things, and discloses an Internet of Things code scanning device capable of resisting light interference, which comprises a shell; a sliding block is slidably connected to the inner wall of the shell, a driving wheel is fixedly connected to the front surface of the sliding block, a reset rope is fixedly connected to the top of the sliding block, a shading plate is slidably connected to the interior of a sliding box, a reset spring is fixedly connected to the top of the shading plate, a driving wheel is fixedly connected to the interior of the driving wheel, and sliding teeth are slidably connected to the interior of the driving wheel. According to the Internet of Things code scanning device capable of resisting light interference, the resistance value of the photoresistor is reduced, the photoresistor increases the magnetic force of the suction block, the suction block drives the magnetic block to descend, the magnetic block drives the piston rod to descend, the piston rod descends to ventilate the air pipe, the air pipe ventilates the air hole, the air pressure pushes the piston block to descend, the piston block drives the shading plate to descend, and through cooperative use of a shading plate and a sliding box, the effect of preventing strong light interference is achieved.

Description

technical field

[0001] The invention relates to the technical field of the Internet of Things, in particular to a code scanning device for the Internet of Things that can resist light interference. Background technique

[0002] The Internet of Things refers to the extension of the concept of the Internet to the connection between physical devices and everyday objects embedded with electronics, network connections and other forms of hardware (such as sensors) that can communicate and interact with other people through the network, And it can be monitored remotely. Among them, the code scanning gun is a relatively common IoT device, and the code scanning gun is mainly used to enter the information of the product into the computer.

[0003] Existing code scanning guns have high requirements on lighting conditions when scanning codes. If they encounter direct sunlight or strong light, the photosensitive device will enter the saturation area, resulting in failure to scan the barc...
