RFID technology based electric window curtain circuit

Abstract

The invention discloses an RFID technology based electric window curtain circuit. The RFID technology based electric window curtain circuit comprises an AC power supply, a button, RFID label buttons, a transformer, an indicator light, a rectifier, a resistor, a first capacitor, a second capacitor, a first relay, a second relay, a first travel switch, a second travel switch and a motor. The electric window curtain circuit needs few elements, and is high in reliability, and convenient to operate; one button is generally used to control a window curtain to open and close; when the window curtain is opened and closed in place, the 220V AC power is automatically cut off by the circuit, so that the economy and safety are ensured; another button can be used for enabling the window curtain to be stopped in any position as requirement; meanwhile, the RFID technology is carried out, and therefore, the electric window curtain can be controlled without manually pressing the button to open and close, and as a result, both time and force can be saved, and the practicability is ensured.

Description

technical field [0001] The invention relates to a circuit based on RFID technology, in particular to an electric curtain circuit based on RFID technology. Background technique [0002] RFID (Radio Frequency Identification System) is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. Radio signals transmit data from a tag attached to an item through an electromagnetic field tuned to a radio frequency to automatically identify and track the item. Some tags can get energy from the electromagnetic field emitted by the identifier during identification, and do not need batteries; there are also tags that have their own power supply and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). Tags contain electronically stored information and can be identified within a few meters. Unlike barcodes, RFID tags do not need to be in line of sight of the read...

AI Technical Summary

Problems solved by technology

[0003] The electric curtain circuit in the prior art uses many components, the reliability is not high, and the operation is inconvenient. Usually, the button needs to be pressed to control the opening and closing of the curtain, which is uneconomical and has low safety performance.
