Problems solved by technology

However, the traditional access control system needs to continuously supply power to the card reader to ensure the real-time induction and identification of the access control card. Since the power supply is also continuously supplied in most of the spare time, it causes a large amount of power consumption. The cost is high, and it does not meet the needs of green environmental protection

Abstract

A card reading device is used for carrying out identity authentication on an entrance guard card and comprises a power supply module, a wireless tag reader, a switch module and a sensor. The switch module is electrically connected or disconnected with the power supply module and the wireless volume label reader. The sensor is electrically connected to the switch module and is used for detecting the magnetic field change of the entrance guard card; when the card reading device is idle, the switch module is in an open state, and the power supply module does not supply power to the wireless tag reader. When the sensor detects the change of the magnetic field, a detection signal is output to the switch module to close the switch module, and the power supply module supplies power to the wireless tag reader. The invention further provides an access control system comprising the card reading device.

Description

technical field [0001] The invention relates to an energy-saving card reading device and an access control system. Background technique [0002] The traditional access control system mainly adopts radio frequency identification technology, the identifier in the access control card is transmitted, received and demodulated by the card reader, and the legitimacy and validity of the access control card are judged by the read identifier. However, the traditional access control system needs to continuously supply power to the card reader to ensure the real-time induction and identification of the access control card. Since the power supply is also continuously supplied in most of the spare time, it causes a large amount of power consumption. The cost is high, and it does not meet the needs of green environmental protection. Contents of the invention [0003] In view of this, it is necessary to provide an energy-saving card reading device and an access control system. [0004] ...
