As for the conventional belongings monitoring system, a number of patents, such as Japanese Patent Application Laid-Open No. 2005-85186, Japanese Patent Laid-Open No. 2006-227936, Korean Patent No. 0658199, Japanese Patent Publication No. 2003-0055708, Japanese Patent Publication No. 2006-0077970, etc. are proposed. have. However, it can be said that the RFID reader is provided as an integrated structure or an independent tablet structure with a mobile phone, which is a mobile communication terminal, and relies mainly on sound as an alarm means for monitoring. Therefore, it is very inconvenient to carry and manage the RFID reader to monitor the belongings, and it is easy to inadvertently drop it, so there is a high risk of damage and loss, and also when building a communication system with an active RFID tag with a relatively long communication distance, On the contrary, it is impossible to make a rapid response to theft and loss. On the contrary, when constructing a communication system with a passive RFID tag with a short communication distance, it may cause an alarm sound and cause it as a new noise pollution problem.

Accordingly, the present invention is proposed to solve the above-mentioned conventional problems occurring on the belongings monitoring system for preventing the loss and theft of belongings by using the RFID tag for transmitting the radio identification code and the RFID reader for detecting the RFID tag. Based on the introduction of a passive RFID tag that can be monitored at a close range of about 1 ~ 2m in all directions, the RFID reader communicates with the wrist as a watch type that can be worn on the wrist, and a method thereof. It is to make presentation of technical problem.

Therefore, the wristwatch-type belonging monitoring RFID reader of the present invention for carrying out the above problems is provided with a screen for displaying time and alphanumeric characters on the upper surface of the box-type main body, and using known or prior art in the surroundings and the main body. Power supply, transmission / reception antenna, switch group (property monitoring ON / OFF switch, navigation and confirmation key), alarm speaker and light emitting element and vibrating body, information input / output reader and memory and at least one RFID tag information. In order to register and communicate with them, a judgment unit for checking whether or not the response radio wave is received is provided. do.

It will be described below with reference to the drawings of embodiments embodying the present invention.

Fig. 1 shows an example of a belongings monitoring system configuration by the wrist watch type belongings monitoring RFID reader of the present invention which monitors the belongings with a passive RFID tag.

As shown in the figure, the passive RFID tags 1 to 6 are formed of cards, labels, etc., which are durable, and those that can also describe the item name and serial number of the object to be monitored as the distinguishing information of the tag. The objects to which they are attached are all things that are easily lost or stolen while traveling, going to work, or going to school, or which are deemed necessary to be monitored by the holder, eg wallets, keys, passports, bags, luggage, mobile phones, books. , MP3s, memory sticks, and clothing.

When the monitoring object is selected, before or after attaching the passive RFID tags (1 to 6), the numbers (e.g., 001, 002, etc.) and the name of the tags (e.g., mobile phone, bag 1, etc.) Is registered in the watch-type belongings monitoring RFID reader, and the belongings monitoring switch 12 is activated (ON) to start belongings monitoring by communication. At this time, if there is no problem in communication, the screen 10 displays the current time display (e.g., 10:18) along with an active state (e.g. RF), the number of monitored objects (e.g., five), When a warning occurs (e.g. V) is displayed, and a tag is disconnected due to loss or theft during monitoring and communication is lost, the current time display (e.g. 12:55) is shown as shown in FIG. The number of tags (e.g., one) disconnected, the serial number (e.g. 001) of the registration tag, the item name (e.g. bag 1) and the disconnection time (e.g. 12:50) are displayed. For example, when V) is selected, an alarm is generated by the vibrating body built into the main body.

Frequent communication between the watch-type belongings monitoring RFID reader and the passive RFID tag in the present invention consumes a lot of batteries, so that the power supply unit can be charged and reused, for example, using a secondary battery such as a lithium ion battery. It may be desirable. In the present invention, in order to optimize the use of the battery in consideration of this point, belongings monitoring switch that can control the belongings monitoring function ON / OFF in case the belongings monitoring is not necessary, such as when the belongings monitoring is required and when returning home (12), and the communication interval time can be set so that the intervals can be different in the communication for monitoring the belongings.

2 shows an example of how to use a wristwatch belonging monitoring RFID reader.

Using the watch, the belongings monitoring switch 12 is turned on to display the RF on the screen 10 as an active state of the belongings monitoring on the screen 10. The active state, as shown in FIG. 1 of the description). At this time, by touching the switch of any one of the navigation and the confirmation key 13 to open the belongings monitoring menu screen (Fig. (A)). On the menu screen, 1.TAG registration to register serial number and product name as distinguishing information of RFID tag, to check the serial number and product name of registered RFID tag (s) and the current state 2.Registration TAG view, communication interruption Alarm mode to generate a selected alarm and a communication interval time setting mode that optimizes the use of the battery in communication with the RFID tag (s).

In the TAG registration mode menu (FIG. (B)), the individual response that the radio wave transmitted through the internal or external antenna 11 of the belonging monitoring RFID reader is returned from the passive RFID tag (s) within the communication range. Receives a radio wave signal to display TAG-specific ID information, and the user inputs or selects the navigation and confirmation keys 13 or numbers or letters appearing on the touch panel of the screen and writes them on the tag label as distinguishing information of the tag. Register serial numbers and product names in the same order. For example, the information of six tags registered in this way is stored in the storage unit in the order of serial number or Korean alphabet, unless deleted, as shown in the registration TAG view of FIG. If a tag (e.g. 003 handbag) that cannot receive response propagation occurs when the belonging monitoring switch 12 is activated even if the detached tag (e.g., 001 bag 1) and the previously registered TAG, The communication disconnection time (e.g. 12:50) and the time when the belonging monitoring switch 12 is operated (ON) (e.g. 07:03) are set as the communication disconnection time, and the communication is displayed. When the response propagation reception from these disconnected tag (s) is restored to normal, the indications of these communication break times are released so that they can be memorized and displayed in the recognition of the loss or theft of belongings later. Based on the time (s) it will be able to predict to some extent the place of lost or stolen.

And as the alarm mode for the deviation of the communication range during monitoring (d), one of the sound (M), the vibration (V) and the light (L) can be selected (on) or all can not be selected (off). To be These settings can be used to select the optimal monitoring conditions (eg vibration selection in trains, library selection off, hazardous area speaker sound (14), hearing loss light emitting device (16), etc.). This is because it is possible to block the problems that may be caused by indiscriminate noise. And even if the selected alarm is being issued because it is impossible to receive the response signal, it is a matter of course to configure the alarm that was issued when the response signal reception is restored to normal. In the figure (d), the example in which the vibration V was selected (on) is shown.

On the other hand, in the setting of the communication interval time of FIG. E, the periodic transmission interval time of the radio wave can be specified in units of seconds. This allows you to send out radio waves from RFID readers at regular intervals, ranging from a few seconds (attention monitoring in complex places such as station premises, airports, or markets) depending on where your belongings are monitored. (E.g., fixed monitoring of household items), which makes it possible to improve the efficiency of monitoring and to optimize the consumption of batteries consumed by radio waves, compared to the radio wave transmission method of any one time. (E) shows an example in which 5 seconds is set as the communication interval time.

In Fig. 3, the serial number and the product name are registered as the distinguishing information for the six items in Fig. 2 or 12 o'clock under the state of being monitored by activating (ON) the belongings monitoring switch at 07:03. 55 minutes An example of the current belonging surveillance RFID reader screen is shown. 6 items of discrimination information are registered (FIG. 2 (c)), but communication is lost at 07:03 at the ON time of the belonging monitoring switch 12 (003 handbag 07:03, FIG. 2). Among the five cases under normal monitoring (see Fig. 1) except for (c), tags with a broken communication occurred and the number (eg, one) as information about the serial number (eg, one) and registration identification information. , 001) and the item name (e.g. bag 1) and disconnection time (e.g. 12:50), at the same time the set time (e.g. 5 seconds) and the selected alarm (e.g. ) Is also issued by means (e.g., vibrating body) built into the main body. As such, the identification information of the tag displayed on the screen and the command alarm can be released by using the navigation and the confirmation key 13 and the like, and the disconnection time can be returned to the normal reception of the propagation response or the belonging monitoring switch 12. Until it is turned off, the memory is stored in the storage unit as shown in FIG. 2 (C) so that it can be confirmed later.

In the example of the present invention, a method of separately configuring the belongings monitoring switch 12 has been described. In addition, the touch time of any one of the navigation and the confirmation keys 13 is lengthened so that the use of the keys is different from other keys. In addition, it is also well known that various pictograms or other numbers can be cited and displayed in other forms in the manner of displaying a letter or a number as a display function of the RFID reader.
