What kind of problems will arise if you forget to bring your belongings or carry them out? Here are a few of the most common examples, which are briefly explained. First of all, forget to carry the key as an example: If you find it in time, and there are people in your home, you can of course seek help to resolve the crisis. If you live alone or the last one, and the door has an automatic locking function, it may cause a homeless situation. Secondly, I forgot to carry the wallet: Modern people like to put their cash, ID cards and various cards in the wallet. If you forget to bring the wallet out, there may be no money available, no cash card can be used, and more Not to mention a credit card, you often need to ask a friend or colleague for support. Finally, I forgot to bring my mobile phone: Due to the popularity of mobile phone usage, modern people are almost always connected through mobile phones. Forgetting to bring a mobile phone may cause you to lose business opportunities, and it may be caused by family or friends not being able to contact for a long time. Misunderstandings cause unnecessary troubles.

In view of this, the creator is actively and constantly in the spirit of perseverance in response to the inconvenience caused by forgetting to carry objects or carrying objects. Research and improvement, and the use of the characteristics of the radio frequency identification system, finally developed and designed this creation.

The main purpose of this creation is to solve the above problems and provide an electronic warning device that utilizes the characteristics of the radio frequency identification system to prevent the forgetting of carrying articles or carrying articles.

In order to achieve the above purposes, the present invention mainly includes an electronic warning device for preventing the forgotten carrying of articles or carrying articles, and mainly includes a system host and a plurality of signal transceivers for respectively transmitting different frequency waves corresponding to different objects; The system host has a controller, an electromagnetic wave transmitter and a signal receiver capable of simultaneously receiving different frequency waves, a speaker, a display screen and an input interface, the electromagnetic wave transmitter, the signal receiver and the speaker. And the input interface is electrically connected to the controller; and each of the signal transceivers has built-in sensors electrically connected to each other and signal transmitters emitting different frequencies.

With the above combination of structures, when the sensor of each signal transceiver receives the signal from the electromagnetic wave transmitter, the signal transmitter activates a radio frequency, and when the signal receiver of the system host receives all the built-in different frequencies. After the signal, optionally no warning is provided; when the system host does not receive all the signals, after the comparison, the warning will be sent through the speaker with different voices.

The first picture is a schematic diagram of the creation.

This creation is about an electronic warning device that uses the characteristics of the radio frequency identification system to prevent forgetting to carry objects or carry objects. The principle of operation is to use the system host to emit radio waves and touch the RFID tags within the sensing range. By electromagnetic induction Current is generated, the wafer on the RFID tag is supplied to operate and an electromagnetic wave is sent back to the sensor.

Differentiating RFID tags with driving energy sources can be divided into active and passive Kind: Passive tag itself has no battery device, the required current is all generated by the sensor's radio wave electromagnetic induction, so the sensor will only passively respond to the sensor when it receives the signal from the sensor; the active tag has built-in The battery can actively transmit signals for the sensor to read, and the signal transmission range is relatively more passive than passive. Active RFID tags are large in size and are not suitable for use in the technical field of the present invention because of the necessity of built-in power supply. Therefore, the following embodiments are only discussed as passive RFID tags without power supply.

Please refer to FIG. 1 , which mainly includes a system host 10 and The plurality of signal transceivers 20 for transmitting different frequency waves corresponding to different objects, wherein the system host 10 has a controller 11 , an electromagnetic wave transmitter 12 and a signal receiver 13 capable of simultaneously receiving different frequency waves. a speaker 14, a display screen 15 and an input interface 16, the electromagnetic wave transmitter 12, the signal receiver 13, the speaker 14, the display screen 15, and the input interface 16 are electrically connected to the controller 11, respectively, and each signal is transmitted and received. The device 20 is internally provided with a sensor 21 electrically connected to each other and a signal transmitter 22 emitting different frequencies. The signal transceiver 20 can be made into different shapes or aspects for the corresponding objects, such as a card that can be placed in a wallet, or a ring type that can be connected in series with a key ring, or can be attached. A label type or charm on the phone case.

The following embodiment illustrates that the number of the signal transceivers 20 is set to three, and For example, the wallet, the key and the mobile phone are respectively used as an example. Of course, the input interface 16 can be used to change the number of objects to be sensed or to adjust the corresponding voice warning content. Firstly, the system host 10 is installed at a preset position, wherein the position of the gate is most appropriate, and the input interface 16 is used to set the number of the signal transceivers 20, the frequency of the transmitted signals, and the corresponding objects (when implemented, Some of the signal transceivers 20 can be pre-set at the factory, and some of the signal transceivers 20 can be self-set as needed. For example: wallet, key or mobile phone, etc., and displayed on the display screen 15. When the user goes out and carries the wallet, the key and the mobile phone, the sensor 21 of each signal transceiver 20, when receiving the signal from the electromagnetic wave transmitter 12, causes the signal transmitter 22 to emit a signal, when the system host After receiving the three different frequency radio signals, the signal receiver 13 of the 10 starts to compare the built-in resources in the controller 11. At this time, since the user carries the wallet, the key and the mobile phone at the same time, after the comparison is correct, the system host 10 will not provide any warning, so that the user can safely go out. When the user forgets one or more of the set items, the system host 10 cannot receive all the radio signals of different frequencies at the same time, and after comparing, the corresponding object corresponding to the signal transceiver 20 that does not receive the electric wave signal is matched. The speaker 14 is used to voice the warning, and the name of the object corresponding to the unreceived radio signal is displayed on the display screen 15.
