Description

The present disclosure relates to an electronic system, a communication device, and a registration method.

As a method for preventing misplacement of an article, a method using an electronic tag having a short-range wireless communication function such as Bluetooth (registered trademark) has been proposed. First, an electronic tag having a Bluetooth function attached to an article and a mobile terminal device having a Bluetooth function, for example, a smartphone are registered in association with each other (pairing). Then, when a wireless communication link is formed between them and the wireless communication link is disconnected due to the distance between them, an alarm due to sound, light, or vibration is generated on at least one of the electronic tag and the smartphone. ..

The following situations are assumed regarding such a misplacement prevention method. A user attaches an electronic tag to each of a plurality of owned articles. Then, the user carries a smartphone and some of the plurality of articles, places some of the other articles in the house, and goes out. It should be noted that when going out, it is assumed that the user correctly carries all the articles necessary for going out. The user expects that the smartphone or the electronic tag attached to the article will generate an alarm and notify the misplacement if the article being carried is misplaced on the go. However, when the user goes out and leaves the house, the electronic tag attached to the article placed in the house without becoming a property when going out is due to the disconnection of the wireless communication link with the smartphone. And generate an alarm. That is, when the user goes out and decides that the article is unnecessary and is not carried, it is determined that the article is left behind and an alarm occurs. In order to prevent such a situation, there is a known technology for selectively registering an electronic tag attached to an article carried when going out to a smartphone as a target (hereinafter referred to as a monitoring target) for preventing misplacement on the go. Has been.

For example, a user carries out a search for an electronic tag by transmitting a low-output radio wave from the smartphone while wearing a smartphone and something to carry when going out. Since a low-power radio wave is used, only the electronic tag in the close range of the user is detected, and the electronic tag in the position away from the user is not detected. Then, only the detected electronic tag is selectively registered in the smartphone as a monitoring target. After that, when the article to which the electronic tag registered as the monitoring target is attached is left behind on the go and separated from the smartphone, an alarm is generated from at least one of the smartphone and the electronic tag.

If it is determined that the wireless communication link has been disconnected, the processing flow proceeds to step S725, and if it is not determined that the wireless communication link has been disconnected, the processing flow returns to step S717. In step S725, the control unit 215 refers to the monitoring target list 219, confirms that the electronic tag 100 whose wireless communication link has been disconnected is a monitoring target, and notifies the alarm unit 214 of the alarm tag 214. The output device 250 is controlled so that an alarm is generated based on the notification. Then, in process S730, the link unit 211 determines whether the wireless communication link with the electronic tag 100 has been restored. If it is determined that the wireless communication link has been restored, the processing flow returns to step S717, and if it is not determined that the wireless communication link has been restored, the processing flow returns to step S725.

When the process flow proceeds from process S717 to process S740, the control unit 215 resets the monitoring target list 219 in process S740. That is, the control unit 215 deletes the electronic tag 100 from the monitoring target by registering “0” in the “monitoring target” column corresponding to the electronic tag 100 registered as the monitoring target in the monitoring target list 219. Perform processing. After that, the process flow returns to the process S705.

As described above, in the embodiment, when the wireless communication link between the electronic tag 100 attached to the article 1 carried by the user and the base device 400 is disconnected, the electronic tag 100 sends its own ID to the mobile terminal device 200. Send. Accordingly, the mobile terminal device 200 can selectively register the electronic tag 100 attached to the article 1 that the user carries when going out as a monitoring target.

Next, the details of the process of determining the connection by the wireless communication link with the mobile terminal device 200 executed by the electronic tag 100 will be disclosed. FIG. 11 is a flowchart of processing executed by the processor 110 of the electronic tag 100. The process disclosed in (A) of FIG. 11 corresponds to the process S610 of FIG. After processing S605 in FIG. 9, in processing S611, the link unit 111 transmits the advertisement packet at a predetermined time interval. The advertisement packet is a packet that includes the ID of the electronic tag 100, and the electronic tag 100 informs peripheral devices of its existence. When the mobile terminal device 200 is located near the electronic tag 100, the mobile terminal device 200 receives the advertisement packet transmitted from the electronic tag 100 and makes a connection request to the electronic tag 100. In step S612, the link unit 111 determines whether or not there is a connection request from the mobile terminal device 200. If it is determined that there is a connection request from the mobile terminal device 200, the processing flow proceeds to processing S613, and if it is not determined that there is a connection request from the mobile terminal device 200, the processing flow proceeds to processing S614. When the processing flow proceeds to processing S613, the link unit 111 forms a wireless communication link with the mobile terminal device 200 in processing S613, and then the processing flow proceeds to processing S620 disclosed in FIG. When the processing flow proceeds to step S614, in step S614, the control unit 115 determines whether or not a predetermined time has elapsed from the disconnection of the wireless communication link with the base device 400. When it is determined that the predetermined time has elapsed, the processing flow proceeds to processing S645 in FIG. 9, and when it is not determined that the predetermined time has passed, the processing flow returns to processing S612. Thus, when the mobile terminal device 200 is located near the electronic tag 100 when the wireless communication link with the base device 400 is disconnected, the electronic tag 100 wirelessly communicates with the mobile terminal device 200. Communication links can be formed.

In addition, in FIG. 11A, an example in which the electronic tag 100 transmits an advertisement packet and the mobile terminal device 200 performs a search is disclosed, but conversely, in FIG. As disclosed, the mobile terminal device 200 may transmit the advertisement packet and the electronic tag 100 may perform the search.

11B is a flowchart of a processing flow executed by the processor 110 of the electronic tag 100, and is a flowchart when the mobile terminal device 200 transmits an advertisement packet and the electronic tag 100 performs a search. .. The process disclosed in (B) of FIG. 11 corresponds to the process S610 of FIG. After processing S605 in FIG. 9, in processing S615, the link unit 111 continuously executes a search for the mobile terminal device 200. On the other hand, the mobile terminal device 200 transmits an advertisement packet at a predetermined time interval. The advertisement packet includes the ID of the mobile terminal device 200. In process S616, the link unit 111 determines whether the advertisement packet transmitted from the mobile terminal device 200 has been received. When it is determined that the packet from the mobile terminal device 200 is received, the processing flow proceeds to processing S617, and when it is not determined that the packet from the mobile terminal device 200 is received, the processing flow proceeds to processing S618. When the process flow proceeds to process S617, the link unit 111 forms a wireless communication link with the mobile terminal device 200 in process S617, and then the process flow proceeds to process S620 disclosed in FIG. When the process flow proceeds to step S618, the control unit 115 determines in step S618 whether or not a predetermined time has elapsed since the wireless communication link with the base device 400 was disconnected. When it is determined that the predetermined time has elapsed, the processing flow proceeds to processing S645 in FIG. 9, and when it is not determined that the predetermined time has elapsed, the processing flow returns to processing S616. Thus, when the mobile terminal device 200 is located near the electronic tag 100 when the wireless communication link with the base device 400 is disconnected, the electronic tag 100 wirelessly communicates with the mobile terminal device 200. Communication links can be formed.

It should be noted that, in the above-described embodiment, there is no mention of at what timing the wireless device 270 of the mobile terminal device 200 is activated when the user goes out. For example, the wireless device 270 may be activated while the user is at home to establish a wireless communication link with each electronic tag 100, or the wireless device 270 may be activated after the user goes out, and at least an article carried by the user. A wireless communication link may be established with one electronic tag 100. Hereinafter, as a modified example of the embodiment, an example in which the mobile terminal device 200 detects that the user has gone out and activates the wireless device 270 is disclosed. In this modification, the mobile terminal device 200 detects that the user has returned home, the wireless communication link between the electronic tag 100 and the mobile terminal device 200 is released based on the detection, and the electronic tag 100 is connected to the base device 400. Processing is also disclosed.

(Modification of the embodiment)
FIG. 12 is a system configuration diagram in which the mobile terminal device 200 detects a user going out in a modified example of the embodiment. A Wi-Fi access point 300 is provided in the user's house. The mobile terminal device 200 is connected to the access point 300 using a Wi-Fi wireless communication link, and when the user carries the mobile terminal device 200 and goes out, wireless communication between the mobile terminal device 200 and the access point 300 is performed. The link is broken. When the disconnection of the wireless communication link is detected, the mobile terminal device 200 determines that the user has gone out and activates the wireless device 270.

FIG. 13 is a hardware configuration diagram of the access point 300 according to the modified example of the embodiment. The access point 300 includes a processor 310, a volatile memory 320, a non-volatile memory 330, an input device 340, an output device 350, and a wireless device 380. The processor 310 is a hardware processor, and a CPU, MCU, MPU, DSP, FPGA or the like is applicable. The volatile memory 320 is, for example, SRAM or DRAM, and the non-volatile memory 330 is, for example, ROM, mask ROM, PROM, flash memory, MRAM, ReRAM, FeRAM, or the like.

The input device 340 is a touch panel, a key switch, a button switch, etc., and the output device 350 is an LCD, an LED, etc. The wireless device 380 is a communication module having a Wi-Fi communication function.

FIG. 14 is a functional block diagram of the processor 210 of the mobile terminal device 200 in the modification of the embodiment. Functional blocks having the same functions as the functional blocks disclosed in FIG. 7 are designated by the same reference numerals, and description thereof will be omitted. The processor 210 functions as a second link unit 216 and a second link disconnection detection unit 217 in addition to the first link unit 211, the first link disconnection detection unit 212, the alarm unit 214, the control unit 215, and the monitoring target list 219. The first link unit 211 establishes a wireless communication link with the electronic tag 100, and the first link disconnection detection unit 212 detects disconnection of the wireless communication link with the electronic tag 100. Since these functions are substantially the same as those of the link unit 211 and the link disconnection detection unit 212 in FIG. 7, they are designated by the same reference numerals. The second link unit 216 establishes a wireless communication link with the access point 300, and the second link disconnection detection unit 217 detects disconnection of the wireless communication link with the access point 300. When the second link disconnection detector 217 detects disconnection of the wireless communication link, the controller 215 activates the wireless device 270.

The timing at which the wireless communication link between the mobile terminal device 200 and the access point 300 is disconnected due to the user going out is more than the timing at which the wireless communication link between the electronic tag 100 and the base device 400 is disconnected. The earlier the better, the better. That is, it is preferable that the communicable distance of the wireless communication link between the mobile terminal device 200 and the access point 300 is set shorter than the communicable distance of the wireless communication link between the electronic tag 100 and the base device 400. .. Accordingly, when the user goes out and the wireless communication link between the electronic tag 100 and the base device 400 is disconnected, an alarm is generated from the electronic tag 100 because the wireless device 270 is not activated. That situation can be prevented.

FIG. 15 is a diagram showing an outline of processing executed among the electronic tag 100, the mobile terminal device 200, the base device 400, and the access point 300 in the modification of the embodiment. The same processes as the processes disclosed in FIG. 5 are designated by the same reference numerals, and the description thereof will be omitted. It is assumed that a wireless communication link has been established between the mobile terminal device 200 and the access point 300 before the processing disclosed in this figure is started. The user carries out the mobile terminal device 200 and the article 1c and goes out, the wireless communication link between the mobile terminal device 200 and the access point 300 is disconnected, and the mobile terminal device 200 detects disconnection of the wireless communication link in step S502. To do. In response to this detection, the mobile terminal device 200 activates the wireless device 270 in step S512. Further, when the user returns home, the mobile terminal device 200 is connected to the access point 300 in step S532 and the wireless communication link is restored, and this connection is used as a trigger in steps S535 and S540 to set the mobile terminal device 200 and the electronic tag 100c. The connection with the wireless communication link with is ended, and the monitoring target registered in the monitoring target list 219 is reset. Further, triggered by the end of the connection between the electronic tag 100c and the mobile terminal device 200, the electronic tag 100c and the base device 400 are wirelessly connected.

FIG. 16 is a flowchart of processing executed by the processor 210 of the mobile terminal device 200 according to the modification of the embodiment. The same processes as those shown in FIG. 10 are designated by the same reference numerals, and the description thereof will be omitted. After the processing flow is started in processing S700, in processing S702, the second link disconnection detection unit 217 determines whether or not disconnection of the wireless communication link with the access point 300 is detected. If it is not determined that the disconnection is detected, the execution of the process S702 is repeated, and if it is determined that the disconnection is detected, the process flow proceeds to the process S703. In process S703, the control unit 215 activates the wireless device 270, and the process flow proceeds to process S705.

In addition, after the processing S715, in the processing S718, the second link unit 216 determines whether or not the wireless communication link with the access point 300 is restored. If it is determined that the wireless communication link is restored, the processing flow proceeds to processing S740, and if it is not determined that the wireless communication link is restored, the processing flow proceeds to processing S720. In the process S720, if it is not determined that the wireless communication link with the electronic tag 100 is disconnected, the process flow returns to the process S718.

As described above, in the modified example, the mobile terminal device 200 automatically detects that the user has gone out and activates the wireless device 270. Further, when the user returns home, the mobile terminal device 200 automatically ends the wireless communication link with the electronic tag 100. The method in which the mobile terminal device 200 detects the disconnection of the wireless communication link by Wi-Fi is an example of the method in which the mobile terminal device 200 automatically detects the user's going out, and other methods are applied. Good. For example, when the mobile terminal device 200 has a GPS (Global Positioning System) function, it may be detected that the user has left the home by using the GPS function. Specifically, the first position information for specifying the position of the user's house is registered in advance on the map information stored in the nonvolatile 230, and the second position information of the mobile terminal device 200 acquired using the GPS function is By the comparison with the first position information, it may be detected that the user carrying the mobile terminal device 200 has gone out or returned home.

The embodiments and their modifications have been disclosed above.

In the embodiments and the modifications, Bluetooth has been described as an example of the communication standard for short-distance communication between the electronic tag 100 and the mobile terminal device 200, but in the present invention, a wireless communication standard other than Bluetooth may be used. .. Similarly, an example in which Wi-Fi is used as a method of automatically detecting the user going out by the mobile terminal device 200 has been described, but a wireless communication standard other than Wi-Fi may be used in the present invention.

In addition, the embodiments and the modifications have been described on the assumption that the wireless communication function of the electronic tag 100 is a one-to-one connection function. However, the wireless communication function of the electronic tag 100 may be a one-to-many connection function. For example, the electronic tag 100 may be connectable to both the base device 400 and the mobile terminal device 200 at the same time. In this case, the electronic tag 100 can form a wireless communication link with the mobile terminal device 200 before the wireless communication link with the base device 400 is disconnected. Then, when the wireless communication link with the base device 400 is disconnected, the electronic tag 100 uses the wireless communication link already formed with the mobile terminal device 200 to assign the ID to the mobile terminal device 200. You may send it.
