Description

The present invention relates to a carried item check system that uses an RFID tag to prevent forgetting to bring a carried item.

Conventionally, as disclosed in Patent Document 1, a transmitter that radiates radio waves of a predetermined frequency to space, and rectifies the energy of radio waves that are attached to a portable product and used as a power source. There is a forgotten object prevention system comprising a radio wave reflector that radiates radio waves of different frequencies into space, a receiver that receives the radio wave radiated by the radio wave reflector, and an alarm device that issues an alarm by a signal transmitted from the receiver there were. This system always generates radio waves from a transmitter, and the radio wave reflector that receives the radio waves has a specific frequency that differs from the received radio waves by the built-in antenna, inductor, capacitor, rectifier, and crystal oscillator. A “response radio wave” having a frequency is emitted, and the receiver does not issue an alarm as long as the “response radio wave” is continuously received. When the distance between the object with the radio wave reflector attached and the receiver is more than a certain distance and the “response radio wave” is interrupted, an alarm is issued to inform the user that there is something left behind.

JP 2000-187787 A

However, in the past, since the system always transmits radio waves, the system is always in operation even when the user does not check forgotten things, such as at home. For this reason, an alarm is issued when a certain distance or more is left from a carry-on item with a radio wave reflector attached without turning off the power of the forgotten item alarm, and in some cases it can be annoying. In other words, it was inconvenient because the power was turned on and off according to the necessity of monitoring. In addition, since the battery is driven, there is a problem that the battery life is shortened by continuously transmitting radio waves, and the battery needs to be replaced frequently. In addition to such problems, in the example of Patent Document 1, since a radio transmitter / receiver and a radio reflector operate in a one-to-one pair, a plurality of radio transmitter / receivers are required to simultaneously monitor a plurality of items to be carried. There was a problem such as. Even if a single radio transmitter / receiver can monitor a plurality of radio wave reflectors, in order to determine which radio wave reflector is not within the range of the radio wave transmitter / receiver, that is, individual radio wave reflectors. In order to identify the instrument, it is necessary to configure the frequency of the “response radio wave” to be different by changing the type of the crystal oscillator, etc., which raises the cost and is not practical. As a result, when targeting multiple types of belongings, there was a problem that it was impossible to determine what was forgotten.

Accordingly, an object of the present invention is to provide an easy-to-use system for checking out-of-home items that can be checked voluntarily when it is desired to check in-person items. In addition, it is possible to keep the operating time with the battery of the system long and easily check that you have not forgotten to put your belongings in the bag etc. without having to open and check again when the user goes out. In addition, it is possible to monitor a plurality of items at the same time, and to provide a system that makes it easy to know what you have forgotten if you have forgotten.

In order to achieve the above object, according to claim 1 of the present invention, there is provided a system for checking forgetting to carry a portable item, an RFID tag attached to or attached to the portable item, and a radio wave signal to the RFID tag. An RFID reader unit that transmits and receives a response radio signal from the RFID tag and reads the ID information of the tag, a storage unit that stores in advance ID information of at least one RFID tag, and a tag stored in advance Calculate the difference between the ID information and the ID information of the tag read by the RFID reader unit. If there is a difference, or if the response radio wave signal cannot be received, it is determined that there is no difference, and there is no difference. Determines that it has not been forgotten, outputs a determination result signal to the display unit, receives the result signal from the determination unit, and displays the RFID tag that the RFID reader unit could not detect Because of that To switch the display mode for displaying and warning, the battery for supplying power, the activation signal input unit for starting the RFID reader unit, and the usage mode for storing tag ID information and checking forgetting This mode switching unit and the detector for receiving the activation signal are integrated into the detector, and the activation signal input unit is operated when the user wants to check whether he / she has forgotten to carry the item. Thus, when the activation signal is input from the activation signal input unit to the RFID reader unit and the RFID signal is input from the activation signal input unit to the RFID reader unit, the detector operates, while the automatic activation having the activation radio wave transmission unit. baggage checking system is characterized in that radio wave transmitted from the device to operate the detector when the detector to the extent to be received has approached the automatic starter in starting signal receiving antenna Those that provided.

As described above, according to the first and second aspects of the present invention, it is possible to provide an easy-to-use carrying goods check system that is easy to use and can be checked spontaneously when it is desired to check the carrying goods. In addition, it is possible to keep the operating time with the battery of the system long and easily check that you have not forgotten to put your belongings in the bag etc. without having to open and check again when the user goes out. In addition, it is possible to monitor a plurality of items at the same time, and to provide a system that makes it easy to know what you have forgotten if you have forgotten.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the out-of-home carrying goods check system according to the first embodiment of the present invention. In FIG. 1, reference numerals 21 to 23 denote RFID (Radio Frequency Identification) tags that store individual identification numbers. Reference numeral 8 denotes a detector, which is incorporated in the RFID reader unit 1 that communicates with the RFID tag by radio waves, a determination unit 5 that receives a signal from the RFID reader unit and determines whether or not there is an object left behind, and a determination unit 5. The storage unit 51 for storing the ID information of the RFID tag, the display unit 3 for receiving a signal from the determination unit 5 and displaying the presence / absence of a thing left behind to the user, and using a dry battery or a rechargeable battery, etc. A battery 4 to be supplied, a use mode switching unit 6 for switching between a check mode for carrying items, which is a normal operation of the system, and a mode for storing the RFID tag in the detector main body before or when the system is used; An activation signal input unit 7 for activating the device 8 is provided.
These 1, 3, 4, 5, 6, and 7 are integrally stored in a case to constitute a detector 8.

In FIG. 1, RFID tags 21 to 23 are formed by integrating a sesame grain-sized wireless communication IC having an individual identification number information (hereinafter referred to as ID information) and an antenna, and are small and thin. Yes, it is of a size that does not interfere with the use of a notebook or wallet. Some types of mobile phones can be used by hanging them in a strap. In the embodiment, a plurality of RFID tags are used, but the same applies to the case of using one RFID tag.

When receiving an input from the activation signal input unit 7, the RFID reader unit 1 transmits a radio wave and receives a response radio signal including individual ID information returned from the RFID tags 21 to 23. Perform detection operation to output data. As a matter of course, reception is possible when the distance between the detector 8 and the tags 21 to 23 is kept at a communicable distance. In the present embodiment, the use in about 1 m square is assumed.

The use mode switching unit 6 includes a changeover switch, and switches the use mode of the system. In using the system, first, the switching unit 6 is switched to the registration mode, and the ID information of the RFID tag to be registered is stored in the storage unit 51. After the start of use, the switching unit 6 is switched to the normal use mode, and the ID information of the tag included in the response radio wave signal received by the RFID reader unit 1 from the RFID tags 21 to 23 is stored in the storage unit 51. Compare. When the number of items to be registered is increased or changed, the switching unit 6 is switched to the setting mode for use.

  The determination unit 5 has a built-in storage unit 51 for storing the RFID tags 21 to 23 attached to the carry-on item before the user himself / herself. When the RFID reader unit 1 performs the RFID tag detection operation, the ID information of the detected RFID tag is compared with the ID information of the RFID tag stored in the storage device 51 in advance, and the RFID tag ID stored in advance is compared. Calculate the difference with the information. If there is a difference, it is determined that there is an RFID tag that could not be detected by the RFID reader unit, that is, it is determined that there is forgotten, and if there is no difference, it is determined that all of the registered ID information matches. That is, it is determined that the user has not forgotten to hold the signal, and a determination result signal is output to the display unit.

The display unit 3 displays to the user, based on the information output from the determination unit 5, which RFID tags 21 to 23 are not present, that is, what the forgotten items are. In this embodiment, the information is displayed on the liquid crystal display, the LED is turned on, and at the same time, notification is given by sound and vibration.

An example of how to use the present invention will be described below.

First, the user attaches or attaches the RFID tags 21 to 23 to a thing to be carried when going out (mobile phone, notebook, wallet, etc.). Next, after the RFID tags 21 to 23 and the detector 8 are arranged at a communicable distance, the usage mode switching function 6 is operated, and the RFID tags 21 to 23 themselves received from the RFID tags 21 to 23 by the RFID reader unit 1 Is switched to a mode (registration mode) for storing the ID information held by the storage unit 51 of the determination unit 5. In the registration mode, the storage device 51 built in the determination unit 5 is in a writable state and stores ID information sent from the RFID reader unit 1.

In this state, when the user presses the activation signal input unit 7 to activate this apparatus, the RFID reader unit 1 transmits radio waves. The RFID tags 21 to 23 that have received the radio waves drive the received radio waves as driving energy, and transmit response radio signals including ID information possessed by the RFID tags 21 to 23 themselves. The RFID reader unit 1 receives the response radio wave signal and sends it to the determination unit 5. The determination unit 5 sequentially stores the received ID information in a memory inside the determination unit. Here, “registration number 001” is a RFID tag attached as a strap of 21 mobile phone, “registration number 002” is affixed to 22 notebooks, “registration number 003” is affixed to 23 wallet RFID tag.

Next, when the user normally uses the operating mode switching function 6, the RFID reader unit 1 receives the tag ID information of the RFID tags 21 to 23 received from the RFID tags 21 to 23 by the determination unit 5. The mode is switched to the mode (normal use mode) for comparison with the ID information stored in the storage unit 51.

When the activation button of the activation signal input unit 7 is pressed and the apparatus is activated, the RFID reader unit 1 transmits radio waves to the RFID tags 21 to 23. The RFID tags 21 to 23 that have received the radio waves drive the received radio waves as drive energy, and transmit response radio signals including ID information possessed by the RFID tags 21 to 23 to the detector 8. The RFID reader unit 1 receives the response radio signal including the ID information and sends it to the determination unit 5. The determination unit 5 compares the ID information stored in the storage unit 51 and determines that there is an RFID tag that could not be detected if there is a difference, that is, determines that there is something left behind, The signal is output to the display unit 3.

The display unit 3 receives a signal from the determination unit 5 and displays a result and gives an alarm to the user. For example, if the judgment result is “There is a thing left behind”, an alarm is given by a buzzer or vibration, and the registration number of the RFID tag 21 to 23 that could not be detected by a liquid crystal display or LED (RFID attached to the thing left behind) Tag registration number). For example, when the notebook is forgotten, “registration number 002” is displayed. When there is no forgotten item (when all RFID tags 21 to 23 registered with the RFID reader unit 1 are detected), the display unit 3 that has received the determination result signal outputs all the RFID tags 21 without issuing an alarm. Display that ˜23 is detected. As a result, when the user wants to check whether there is anything left behind, the user can check by voluntarily operating the activation signal input unit, and the system can be used without unnecessarily consuming the battery. Of course, when there is no need for confirmation, the system does not perform confirmation, so there is no annoyance because there is no alarm even if the carry-on items are moved away at home. As described above, for example, the user may have forgotten to put his wallet in the handbag he / she has to go out of, but he / she can avoid failure such as going out without being aware of the appearance from the outside.

FIG. 2 is a block diagram showing the configuration of the out-of-home carrying goods check system showing the second embodiment of the present invention. In the second embodiment, the detector 8 can be activated from the activation button of the activation signal input unit 7 and by a radio signal from the automatic activation device. In the figure, reference numeral 12 denotes an automatic starting device, which includes a battery 11, a starting radio wave transmitting unit 10, and an antenna, and is attached to a key or the like as a key holder. In addition to the configuration shown in the first embodiment, the detector 8 is provided with an antenna for receiving the activation radio signal.

In the system according to the second embodiment, it is possible to automatically check whether the user has forgotten to carry his / her belongings without being aware of when going out.
Prepare a key with the automatic starter 12 attached as a key holder, and hold the detector 8 and a bag containing a mobile phone, notebook, wallet, or other portable item with an RFID tag attached or attached in advance. , If it is close to the key, it will be checked for forgotten by sending from the automatic starter. That is, since the operation is performed when the distance between the bag containing the carried items and the key is less than a certain distance, the user is not particularly aware of the use of the system.

The automatic starter 12 should not be in hand before going out, and must be carried when going out, and it is relatively hard to forget (such as a house key, a car key for people who often move by car). Install it. Alternatively, it may be attached to a place such as a front door that is sure to pass when going out, and the detector 8 may be automatically activated when the communication distance is reached.

Since the difference in operation between the first embodiment and the second embodiment is only at the time of activation, the operation at the time of activation will be mainly described. As in the case of the first embodiment, the user uses the use mode switching function 6 and the activation signal input unit 7 to store the ID information of the RFID tag in the storage unit 51 of the determination unit 5, and then The use mode switching function 6 is switched to the normal use mode.

The detector 8 is attached in a key holder shape to a bag that is usually taken out. When approaching the automatic starter 12, the detector 8 starts automatically and has no effect from the viewpoint of forgetfulness prevention, so keep the distance between the detector 8 and the automatic starter 12 until you leave. It is necessary to keep.

When the radio wave transmitted from the activation radio wave transmission unit 10 of the automatic activation device 12 approaches the range that can be received by the activation signal receiving antenna 9 when going out, the detector 8 is activated in the same manner as when the activation button 7 is pressed. Subsequent operations are the same as those in the first embodiment. The startup radio wave transmission unit 10 is set to intermittently transmit radio waves and suppress battery consumption.

In the case of the first embodiment, the user manually presses the start button for confirmation, whereas in the second embodiment, the detector automatically starts and confirms just before going out, so it is more difficult to forget things. effective. In addition, since the start button 7 is also provided, it is possible to manually check forgotten items when it comes to mind.

Since it is effective for forgetting to bring carry-on items, it can be used not only at home but also for checking the carry-on of essential carry-on items, for example, at construction sites and hospitals.

It is the figure which showed the block diagram which shows the structure of the carrying goods check system at the time of going out by 1st Example. It is the figure which showed the block diagram which shows the structure of the carrying-out goods checked system by the 2nd Example.
