  FIG. 1 is an overall device configuration showing an embodiment of a portable device in a house according to the present invention.

  In FIG. 1, a portable device 10 in a house is attached to an infant 12 that is a use target in a house. In the illustrated example, a wristband-shaped object is attached to the wrist of the infant 12, but it may be an ankle or other parts. Also, the shape is not limited to the wristband, and other methods such as wearing a belt-like material on the waist are possible.

  The information display device 50 includes a communication unit 52 and a display unit 54, and is carried by a guardian (not shown) who monitors the infant 12, and display data of alarm contents according to conditions set in advance from the in-house portable device 10 according to the situation of the infant. 48 is received by the communication unit 52 and displayed on the display unit 54.

  The information display device 50 is preferably carried by a guardian at all times during monitoring. However, the information display device 50 may be installed in a place where the guardian mainly works in a house, and in that case, it may be installed in a plurality of places. The number does not matter.

  The wireless tags 16a and 16b are installed on the objects 18a and 18b. In the illustrated example, wireless tags 16a and 16b processed into labels or stickers are respectively attached to an electric pot 18a existing in the communication area 14 which is one of the objects and a microwave oven 18b outside the communication area. However, the installation method may be other methods such as attaching a packaged wireless tag with an adhesive tape.

  Here, the wireless tag is a so-called RFID (Radio Frequency Identification) tag. In this embodiment, the wireless tag is a passive wireless tag including an ultra-small ID identification semiconductor chip and an antenna capable of wireless communication.

  When the wireless tag detection unit 20 of the portable device 10 in the home approaches the wireless tags 16a and 16b, an electromotive force is generated in the wireless tag by electromagnetic induction from the radio wave (communication confirmation data 22) from the wireless tag detection unit 20, and this power After that, the circuit works, and then an identifier (tag ID) stored in advance is transmitted as communication response data 24 to the wireless tag detection unit 20.

  The wireless tag is not limited to the electromagnetic induction method as long as it is a passive type, but other methods such as an electromagnetic coupling method, an electrostatic coupling method, and a microwave method may be used. The electromagnetic induction method is desirable because of cost.

  The in-home portable device 10 includes a wireless tag detection unit 20 that reads a tag ID that is an identifier when a wireless tag 16a installed in the electric pot 18a, for example, is detected in the communication area 14, and a tag ID. Database 26 that associates the risk level and learning information of the objects 18a and 18b with each other, a setting unit 28 that sets the storage contents of the database 26, an external interface 30 when setting is performed by an external device, and an alarm process corresponding to the tag ID A control unit 32 that controls the sound, a sound output unit 42 such as a speaker that emits an alarm by sound according to alarm processing, a notification unit 40 having a warning light 44 such as an LED that emits an alarm by light, a place where the infant 12 is located, Data for displaying the status on the information display device 50 and a transfer for transmitting an external control signal to an object such as locking the hot water supply function of the electric pot 16a. Made up of part 46.

  Although not shown, it is more effective if the notification unit 40 has a vibration unit such as a vibrator that issues an alarm by vibration.

  Further, the control unit 32 searches the database 26 for the risk level corresponding to the tag ID and extracts the risk level, and performs alarm processing when the risk level is high according to the risk level extracted by the database management unit 34. An alarm processing unit 36 to perform and a learning processing unit 38 to perform learning processing when the degree of risk is low are provided.

  The control unit 32 is realized by computer hardware including a CPU, a ROM, and a RAM. When the computer is started, the OS is read and arranged from the ROM to the RAM, and then executed and read from the RAM to the RAM as an application program. When executed by the CPU, the functions of the alarm processing unit 36, the learning processing unit 38, and the database management unit 34 are obtained. The database 26 is stored in a rewritable storage device such as a ROM or EEPROM, and is read out and arranged in the RAM when the computer is started.

  Here, the wireless tag detection unit 20 always transmits and monitors communication confirmation data 22 as to whether or not the wireless tags 16a and 16b as communication partners are present in the communication area. When the wireless tags 16a and 16b exist in the communication area 14, the wireless tag detection unit 20 receives the communication response data 24 from the wireless tags 16a and 16b.

  That is, the wireless tag 16a installed in the electric pot 18a existing in the communication area 14 is detected, but the wireless tag 16b installed in the microwave oven 18b outside the communication area 14 is not detected.

  2 and 3 show examples of tables stored in the database 26 shown in FIG. In the present embodiment, the database 26 includes a processing table 56 shown in FIG. 2 and an object table 58 shown in FIG. 3. The processing table 56 uses a risk level as a key to output an alarm, a transfer output, and learning information. The object table 58 is composed of a plurality of records whose fields are the installation location, the degree of risk, the learning information, and the external control information with the tag ID, which is the identifier of the wireless tag, as a key. .

  In the processing table 56, the risk level is composed of four stages, with the lowest level being “1” and the highest level being “4”, and “OFF”, “CAUTION”, “ALARM” are output as alarm outputs according to the risk level. "", "Notification", "alarm" as the transfer output, and "on", "off" as the learning information output.

  Here, “OFF” of the alarm output means that nothing is notified, and “Caution” indicates that it is dangerous when the infant 12 approaches the objects 18a and 18b, for example, an electronic sound or “Do n’t get closer. Is a voice message such as “No” or “Sound” is output once or for a short time, and “Alarm” is a loud sound that makes a buzzer feel urgent while the objects 18a and 18b exist in the communication area 14 It keeps outputting and stops when it no longer exists.

  Similarly, “OFF” of the message output means that nothing is notified, and “notification” indicates that the infant 12 has approached the dangerous objects 18a and 18b to the guardian by, for example, electronic sounds or words. The sound is output only once or for a short time. The “alarm” is a loud sound such as a buzzer and the location of the objects 18a and 18b while the objects 18a and 18b are present in the communication area 14. It keeps outputting and stops when it no longer exists.

  In addition, alarm output and transfer output can be dealt with not only by voice alarm but also by light alarm by lighting or blinking of LED etc. or vibration alarm by vibrator etc., even if surroundings are noisy due to noise etc. .

  The learning information output “ON” or “OFF” depends on whether or not the learning information corresponding to the tag ID stored in the object table 58 is output by voice when the infant 12 approaches the objects 18a and 18b. is there.

  Here, in the present embodiment, when the risk level is “3” or higher, the alarm processing unit 36 shown in FIG. 1 performs processing, and when the risk level is “2” or lower, the learning processing unit 38 performs processing. Further, even when the learning mode is the risk level “3” or “4”, the learning processing unit 38 always performs the process by treating the risk level as “2”.

  In the object table 58, the tag ID is a unique identifier of each of the wireless tags 16a and 16b installed on the objects 18a and 18b, and the installation location is the place where the wireless tags 16a and 16b are installed, that is, the object These are the objects 18a and 18b, and the risk level corresponds to the key of the processing table 56, and the risk level of the objects 18a and 18b with respect to the infant 12 is set.

  As learning information, content that is output by voice corresponding to the learning information output of the processing table 56 when the infant 12 approaches the objects 18a and 18b, for example, voice data that records English readings of the objects 18a and 18b is registered. Yes.

  As the external control information, when the infant 12 approaches the objects 18a and 18b, a method for performing some control on the objects 18a and 18b for avoiding the danger is set. In the embodiment, the entrance has a risk “3”. However, the microwave oven, electric kettle, and gas range are at risk “4”, and are set to “stop operation”, “hot water supply lock”, and “gas stop”, respectively. .

  FIG. 4 is an example of a floor plan showing the installation locations of the wireless tags 16a and 16b set in the object table 58 shown in FIG.

  The example shown is a typical two-story house. On the first floor is the entrance, bathroom, Japanese-style room, toilet, living room / dining room, kitchen, and the stairs going up to the second floor. On the second floor is the study, bedroom, toilet, and veranda. And the staircase that goes down to the first floor is laid out.

  Here, reference numerals 0001 to 0020 indicated by four digits are tag ID numbers which are keys of the object table 58 shown in FIG. 3, and the destinations indicated by the reference numerals 0001 to 0020 are set in the objects 18a and 18b, respectively. Wireless tags 16a and 16b.

  Further, the tag ID of the embodiment is a 4-digit numerical value (numerical value), but any tag ID can be used as long as it is expressed as a symbol string according to some form.

  The setting unit 28 shown in FIG. 1 includes an input device (not shown) for setting and registering a table stored in the database 26.

  As the input device is a size that can be carried by the infant 12, the limit is to provide a microphone for recording learning information and several buttons, such as a menu selection button, a cancel button, and a confirmation button. In order to input the installation location and learning information of the object table 58 shown in FIG. 3, complicated operations are required. Therefore, the table can be set more efficiently by providing the external interface 30 and using an external device such as a dedicated input device or a personal computer.

  Setting work is possible for both the processing table 56 shown in FIG. 2 and the object table 58 shown in FIG. 3, but since the setting conditions are complicated, the processing table 56 is set in advance. It is more practical to use as it is without changing and to set only the object table.

  FIG. 5 is a flowchart showing the operation of the control unit 32 shown in FIG. First, when the portable home device 10 is turned on in step S1, the control unit 32 starts processing, and the database management unit 34 refers to the database 26 and registers the contents to be controlled.

  Subsequently, in step S2, the control unit 32 instructs the wireless tag detection unit 20 to transmit the communication confirmation data 22 for supplying power to the wireless tags 16a and 16b, and the wireless tag detection unit 20 transmits the communication confirmation data 22 to the wireless tag detection unit 20. Send.

  Next, in step S <b> 3, the control unit 32 determines whether the wireless tag detection unit 20 has received the communication response data 24. If it is determined in step S3 that the wireless tag detection unit 20 has received the communication response data 24, the process proceeds to step S4, where the tag ID is demodulated from the tag data of the received communication response data 24, and the tag ID obtained in step S5. The database 26 is searched to obtain the corresponding record.

  Next, in step S6, it is confirmed whether it is used in the learning mode. If it is in the learning mode, the process proceeds to step S9 and the learning process is executed. If it is not in the learning mode, the process proceeds to step S7. Check if it is “3” or more.

  If it is determined in step S3 that the risk level is “3” or higher, an alarm process is executed in step S8. If the risk level is not “3” or higher, that is, if the risk level is “2 or lower”, the process proceeds to step S9. Execute learning process. Such processes of steps S3 to S9 are repeated until a stop instruction is issued in step S10.

  FIG. 6 is a flowchart showing details of the alarm processing in step S8 in FIG. In FIG. 6, first, it is determined whether or not the degree of danger passed from the main routine in step S1 is “3” or less. If the degree of danger is “3” or less, the process proceeds to step S2, and a notification unit is output as an alarm output. 40 is instructed to output “CAUTION”, and then in step S3, the notification unit 40 is notified of “CAUTION” by instructing the transfer unit 46 to output “NOTICE” as a transfer output. The unit 46 transmits display data 48 related to “report”.

  If it is determined in step S1 that the degree of danger is not "3" or less, it is checked in step S4 whether the degree of danger is "4" or more. If the degree of danger is "4" or more, an alarm is output in step S5. Instructing the notification unit 40 to output the “alarm”, and then instructing the output of the “alarm” to the transfer unit 46 as the transfer output in step S6, the notification unit 34 notifies the “alarm”. The transfer section 46 transmits display data 48 related to “alarm”.

  If there is control method data in the external control information field corresponding to the tag ID of the object table 58 shown in FIG. 3, the transfer unit 46 transmits a control signal to the object at this time. For example, if the tag ID is 0008, by transmitting a signal for locking hot water supply in the electric pot 18a, the control means (not shown) controls the operation of the hot water supply valve opening / closing means (not shown) in the electric pot 18a.

  The alarm output is continued until the wireless tags 16a and 16b installed on the objects 18a and 18b do not exist in the communication area 14 of the in-home portable device 10, so that the tag data of the wireless tags 16a and 16b in step S7. It is determined whether reception has been turned off, alarm output continues while tag data continues to be received, and when tag data is not received, the process proceeds to step S8 to stop the alarm and return control to the main routine. .

  In addition, when a control signal is transmitted to the objects 18a and 18b and operation restriction is performed, a signal for canceling the operation restriction can be transmitted in accordance with the stop of the alarm, but this is not essential.

  FIG. 7 is a flowchart showing details of the learning process in step S9 in FIG. In FIG. 7, first, in step S1, it is determined whether or not the degree of danger passed from the main routine is “2” or more. If the degree of danger is “2” or more, the process proceeds to step S2 as a message output. By instructing the transfer unit 46 to output “report”, the transfer unit 46 transmits display data 48 related to “report”.

  If it is determined in step S1 that the risk level is not “2” or higher, the process proceeds to step S3 to determine whether the risk level is “2” or lower. If the risk level is “2” or lower, In step S4, the notification unit 40 is instructed to output English sound of the objects 18a and 18b as learning information output, and the sound output unit 42 of the notification unit 40 performs English sound output.

  If the control is returned to the main routine as it is after the output of the English speech, the learning process is repeated many times while the objects 18a and 18b exist in the communication area 14, so the tags of the wireless tags 16a and 16b in step S5. It is determined whether or not the data reception is turned off. The loop is performed while the tag data is continuously received, and the control is returned to the main routine of FIG. 5 when the tag data is not received.

  As described above, according to the in-house portable device 10 of the embodiment of the present invention, when the infant 12 approaches the electric pot 18a that is the object, the wireless tag detection unit 20 detects the tag ID of the wireless tag 16a, The database 26 is searched with the tag ID to obtain a record of the electric pot 18a. Since the danger level of the electric pot 18a is “4”, an alarm is issued from the notification unit 40 as an appropriate danger process, and an alarm is issued from the transfer unit 46 to the information display device 50.

  When the in-home portable device 10 is operating in the learning mode, the learning process is performed without performing the alarm process even though the risk level of the electric pot 18a is “4”, and the voice output of the notification unit 40 is performed. The unit 42 outputs “electric kettle”, which is learning information of the electric pot 18a, by voice.

  Accordingly, the in-home portable device of the present invention can monitor all the objects that require an alarm when the infant approaches, and outputs the learning information as a voice when the risk of the object is low, It is useful not only as an alarm device but also as a learning device.
