Abstract
In this invention a low-cost and low-power consumption RFID electronic lock system is disclosed. The developed electronic lock system engages smart RFID tags which is integrated with the electric locks or electromagnetic locks. To reduce the cost and power-consumption of the system, the smart tag is only activated when it receives a signal from the readers (i.e. smart phone or conventional RFID readers). When the smart tags receive a signal (password key) from the readers (smart phone that carried by users), the wake up circuit turns on the microcontroller that is incorporated with the smart tag and process the received data. Thus, only particular users who will provide the correct password can open the electronic lock system. Since the disarming electronic lock system incorporates relatively inexpensive passive or semi-passive smart RFID tags, it is useful in such application as smart buildings (cost-effective multi-doors electronic lock system), electronic furniture locking systems, and smart electronic luggage locks.

The present disclosure relates to electronic locks more particularly to a low-cost and low-power consumption smart RFID electronic lock system.
BACKGROUND OF THE INVENTION
Radio frequency identification (RFID) has become one of the fastest growing wireless technologies. RFID technology is rapidly spreading over a wide range of industries and consumer services. Indeed, many industries have entered into a new business process stage as a result of rapid development of RFID systems. Various bands such as low frequency (LF) (125 KHz to 135 KHz), high frequency (HF) (13.56 MHz), ultra high frequency (UHF) (860 to 960 MHz), and microwave frequency (MW) (2.4GHz to 2.4835GHz and 5.8 GHz) bands are dedicated to RFID
applications. A typical RFID system is composed of a tag and a reader. The RFID reader is the expensive part in the RFID system.
The RFID tag is composed of an antenna and a microchip. In almost all of RFID
applications an RFID integrated circuit (IC) is attached to the tag antenna to store identification data and respond to the reader. Based on the way the tag is powered, RFID tags can be classified into three different categories: active, semi-active and passive RFID tags. Active and semi-active RFID tags have their own power source for powering the microchip. An active tag also contains a transmitter to communicate with the reader. While the semi-active tag uses the battery only for powering up the microchip, but relies on backscattering (like a passive tag) to transmit data back to the reader.
Passive RFID tags do not contain any source supplying power to the microchip.
Thus, passive RFID
tags are inexpensive and have limited readable ranges. Passive RFID tags only operate in the presence of the electromagnetic field of the RFID reader as they generate the power from the RF
signals received by the tag antennas and transmit its information back. This power should be higher than the threshold needed to turn the chip on. Because the passive tag has a limited supply of power, typically no more than simply a simple ID number is transmitted in a limited reading range.
Currently, RFID systems play an important role in various industries which rely on access control system. The current RFID electronic lock system that is available in the market comprises passive RFID tags and RFID readers to form the electronic access control system. The passive tags use transmitted signal by a reader adjacent to the door to power up the microchip and transmit its information back. In this system the transmitter circuit of the reader is always on to provide sufficient energy to the passive tag. The electric lock is also incorporated with the reader. Thus, users who will provide the correct ID will be able to open the RFID electronic lock system.
However, this method is only useful for a public door or public parking.
The cost, size, and the consumption power of the readers eliminate the widespread use of this technology in electronic lock system applications. For example, in smart buildings there are many doors where each door frame will include the reader transceiver to transmit signals to read the passive tags that are carried by users. Thus, the cost of the system will dramatically increase by increasing the number of relatively expensive active readers installed. In addition, increasing the number of active readers installed require extremely large amounts of power. As a result, the commercial batteries will not be suitable to provide the required power to a stand-alone RFID electronic lock system for long life-time operation. Also, implementation of this system in other applications such as electronic furniture locking systems, and smart electronic luggage locks will not be convenient due to the cost and the large amount of power required to operate this system.
Consequently, a low-cost and low-power consumption miniaturized RFID
electronic lock system for modern application needs to be developed.
SUMMARY OF THE INVENTION
In this invention, low-cost and low-power consumption miniaturized RFID
electronic lock system is developed. The developed new system utilizes smart- passive or semi-passive RFID tags in combination with electric locks or electromagnetic locks to form low-cost, low-power consumption miniaturized RFID electronic lock system. The developed system, change the functionality of the RFID reader in the traditional RFID access control system with relatively inexpensive smart RFID tags. Thus, the tags will be able to receive data from the reader, store the data in its memory and also take actions i.e lock or unlock the electric latch of lock. Definitely, the new RFID electronic lock system will be implemented in many modern applications such as smart buildings, electronic furniture locking systems, and smart electronic luggage locks The developed system utilizes smart tags. The smart tag is incorporated with low power microcontroller and wake up circuit. The smart tag is only activated when it receives a signal from the reader (i.e smart phone or compact RFID reader carried by users). The reader signal will activate the smart tag and also will store password in the tag memory.
Meanwhile, the wake up circuit will wake up the microcontroller to check the password that was sent by the users.
The microcontroller then will send a signal to the electric lock or electromagnetic locks to lock or unlock the system. If the password that was sent by the user was correct, the Microcontroller will inform the electric lock to unlock the system and then to reset the memory of the smart tag. After that the smart tag will be ready to receive a signal and a password form other users.
In this invention the reader can be a smart phone or a compact RFID reader that will be specifically designed for this smart RFID electronic lock system. In this arrangement (for example in smart home application), the relatively inexpensive smart tags will be installed in each door in the smart buildings. Since the developed RFID electronic lock system is miniaturized and consume very low power, it is suitable for many modern applications such as electronic furniture locking systems, and smart electronic luggage locks.
This invention provides for the use of a low-cost, low-power consumption miniaturized electronic RFID lock system for various modern applications span from electronic and electrical devices, electronic furniture locking systems, and smart electronic luggage locks, vehicle smart locks to smart buildings.
Various bands such as low frequency (LF) (125 KHz to 135 KHz), high frequency (HF) (13.56 MHz and 433 MHz), ultra high frequency (UHF) (860 to 960 MHz), and microwave frequency (MW) (2.4GHz to 2.4835GHz and 5.8 GHz) bands are dedicated to this invention.
