Description

High-frequency RFID (radio frequency identification) key forgetting prompting system

Technical Field

The utility model relates to a forget the key reminder system, especially relate to a forget the key reminder system based on high frequency RFID.

Background

People forget to take keys occasionally when going out, and especially the old people have weak memorability and are easy to forget to take the keys, which brings many troubles. The general security door does not have the function of reminding people of carrying the key, so that the problem that people forget to carry the key is difficult to solve.

Although the fingerprint lock and the password lock on the market can be unlocked only by pressing the corresponding fingerprint or inputting the password, the fingerprint lock is easy to lose effectiveness for some patients with poor fingerprint identification or fingerprint diseases; the password lock can be snooped by others and forgets the password of the password lock for the old, so that a simple and practical tool for reminding people to remember to carry the key is needed.

From the existing reminding devices on the market, the reminding devices have no anti-theft function, and also have no function of enabling a user far away from home to know the condition when the door is opened.

Disclosure of Invention

In order to solve the problem, the utility model provides a high frequency RFID forgets key reminder system makes things convenient for people to remember the condition when carrying the key and understanding the door through the SMS when going out, also can prevent burglary.

A high-frequency RFID key forgetting prompting system comprises a high-frequency RFID tag and a control module, wherein the high-frequency RFID tag is hung on a key string as a label, the control module is embedded in any position in a door, and the control module comprises a single chip microcomputer, an RFID reader-writer, a voice synthesizer, a door opening sensor, a power supply and a short message module; the RFID reader-writer is connected with the I/O of the single chip microcomputer, the voice synthesizer is connected with the output interface of the single chip microcomputer, the door opening sensor is arranged at the edge of the door frame, which is attached to the lock groove, and is connected with the I/O interface of the single chip microcomputer, the power supply is connected with the VCC interface of the single chip microcomputer, and the short message module is connected with the I/O interface of the single chip microcomputer. The utility model discloses based on the RFID technique, judge through the matching of RFID read write line and RFID label that the user goes out and carried how much the key, can also tell the user that the door has been opened and not detected the key for appointed phone sending SMS through SMS module when not detecting the key.

Forget key reminder system can install the optional position in the door, wherein the optional position at the door frame edge that door frame and locked groove correspond is installed to the sensor.

Furthermore, the high-frequency RFID label is used for being matched with the RFID reader-writer, so that the RFID reader-writer can know the number of keys carried by a user when the user leaves the door.

Further, the control module comprises a single chip microcomputer, an RFID reader-writer, a voice synthesizer, a door opening sensor, a power supply and a short message module; the door opening detection device is used for detecting whether the door is opened or not and sending a prompt short message and a voice alarm prompt to a user.

Has the advantages that: the utility model discloses need hang passive high frequency RFID label on the key chain as the sign when using, fixed RFID read write line links to each other with the singlechip of inlaying in the door, judges whether the user carries the key through whether the read write line matches corresponding label when opening the door, then realizes corresponding alarm, and the suggestion user takes the key to go out again. The utility model has the characteristics of it is following: (1) if the RFID reader-writer searches for and matches the electronic tag when the user goes out, the system can report the detected number of keys to the user through the voice synthesizer, so that when one person goes out, the user can know the number of keys carried by the person; (2) the short message module sends a short message to a user at the first time when the door is opened and the key is not detected, and then an alarm is given through the voice synthesizer, so that the user can know that the user does not carry the key when the door is opened; (3) when a thief or other persons who are not good will open the door, the user can send a short message to the user at the first time without detecting the key, even if the system is damaged due to the fact that the persons who are not good will are frightened by the voice synthesizer, the user can know that the door is stolen at home, and therefore the theft prevention can be realized; (4) the operation different from ordinary life is not needed to be added when the device is used, and the use is simple and convenient.

Drawings

FIG. 1 is a schematic diagram of the structure of the present invention; fig. 2 is a flow chart of the present invention.

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Detailed Description

As shown in fig. 1, the intelligent door lock comprises a high-frequency RFID tag and a control module, wherein the high-frequency RFID tag is hung on a key string as a label, the control module is embedded in any position in a door, and the control module comprises a single chip microcomputer, an RFID reader-writer, a voice synthesizer, a door opening sensor, a power supply and a short message module; the RFID reader-writer is connected with the I/O of the single chip microcomputer, the voice synthesizer is connected with the output interface of the single chip microcomputer, the door opening sensor is arranged at the edge of the door frame, which is attached to the lock groove, and is connected with the I/O interface of the single chip microcomputer, the power supply is connected with the VCC interface of the single chip microcomputer, and the short message module is connected with the I/O interface of the single chip microcomputer.

The working principle is as follows: the utility model discloses can realize two functions: firstly, reminding a user to carry keys or carry a number of keys when going out; secondly, the function of the anti-theft system is realized based on the matching of the RFID reader-writer and the high-frequency RFID electronic tag, when the anti-theft system is matched with the high-frequency RFID electronic tag, the user is indicated to carry the key, and at the moment, the voice synthesizer is triggered to remind the user of how many keys are carried; when the key is not matched, the user does not carry the key, the system firstly starts the short message module to send a short message to the user to tell the user that the door is opened and the key is not detected, and the system also reminds the user to carry the key through the voice synthesizer. In this way, the user is reminded to go out and carry the key and know that people who are not good at home are not in the first time. The system implementation process is shown as the following example: as shown in fig. 2, when a user opens the door, the door opening sensor senses that the distance between the door frame and the side of the lock slot is increased and transmits a starting signal to the single chip microcomputer, the single chip microcomputer starts the RFID reader to start searching and matching a nearby high-frequency RFID electronic tag, and if the tag is searched, the voice synthesizer is triggered to tell the user how many keys are carried; if no label is searched nearby within 300 milliseconds, the user does not carry the key, a signal is transmitted to the single chip microcomputer, the short message control module sends a short message to the user to tell the user that the door is opened and the key is not detected, and after the short message is sent, the single chip microcomputer starts a voice synthesizer to remind the user of carrying the key when the user goes out.

The embodiments of the present invention are not limited to the above embodiments, and various changes made without departing from the spirit and scope of the present invention are within the scope of the present invention.
