However, the presence of a person is expressed by combining various information such as the presence of a person, the movement of a person, the lighting of a light, and the strength of sound. In addition, when expressing the presence of a person among families, the presence that one wants to know varies among families depending on the other party. For example, in the case of a family with a plurality of children who live away from their parents, the health status of the parents is always anxious for each child, so it is important to know. On the other hand, brothers and sisters are not as worried as their parents are concerned. Also, if a grandchild has just been born, it is natural that he wants to know if the grandchild is growing well. That is, the degree of wanting to know about the other party depends on the degree of intimacy.

In conventional communication terminals, if the speed at which a person is moving changes, the sensor information can only be transmitted to control lighting, etc., reflecting the intimacy that differs between families living apart from each other. , There was a problem that the sense of connection between people could not be displayed properly.

Therefore, the present invention aims to realize a safe display system that can appropriately detect the activity status of a family living in a remote place and can express the detected activity status casually at the other end while taking into account the intimacy between the families. And

Furthermore, the display device of the safe display system according to the present invention has a weight setting operation unit for a user to set and operate the weight for each transmission-side control device, and the storage unit stores the weight set from the weight setting operation unit. You may do it.

According to the present invention, even when the intimacy that the user thinks changes, it is possible to display the reflection, and it is possible to more appropriately display a sense of connection between people.

  According to the present invention, since the activity index calculated by combining information from various sensors is transmitted and displayed by reflecting the intimacy of the place where he / she thinks, the intimacy is high among those living apart from each other. It is possible to provide a safe display system that can be felt accurately with emphasis on the family.

Hereinafter, with reference to FIG. 1, the safe display system 1 which is an example of embodiment of this invention is demonstrated. Moreover, with reference to FIG. 2, the example of arrangement | positioning of each part of the relief display system 1 is demonstrated.

The safe display system 1 includes a plurality of safe display units 2 connected via a network 3.

The safety display units 2 are respectively installed in buildings where families living apart from each other live. Examples of living apart from each other include an independent parent, a student living alone, an OL, a single person, and the family. Since FIG. 1 shows the case where three safety units 2 are used, the safety display unit 2a is provided in three places, for example, the parents' home, the safety display unit 2b is provided in the apartment of the single employee's older brother, and lives alone. The case where the safe display unit 2c can be installed in the sister's apartment is shown.

The network 3 is a wide area communication network such as the Internet.

One of the safety indication units 2 detects the activity of the person in the building, calculates an activity index indicating the activity status based on the detection result, transmits it to the other safety indication units 2, and receives the activity index. Unit 2 performs display based on the activity index. This provides a sense of “connection” that transcends space without interfering with the lives of those who live apart from each other.

The activity index is calculated higher as the human activity is more active. In the present embodiment, an activity index when there is no activity is 0 (reference value), and an activity index when the activity is most active is 5. A 6-level activity index is calculated.

The safe display unit 2 includes a switching unit 4, various sensors 5, and a display device 6 connected to a control device 7, and the control device 7 is further connected to the network 3.

Returning to FIG. 1, the display device 6 is a device that displays the state of family activities in a remote building in a recognizable manner. The display device 6 is configured such that a light emitting unit composed of a plurality of LEDs (Light Emitting Diodes) is covered with a transmissive cover.
The light emitting part is composed of 19 LEDs in total of 5 red, 7 green and 7 blue. The amount of light is adjusted by controlling the number of LEDs to be lit, and the color temperature is adjusted by controlling the proportion of the LED color to be lit.
The cover is made of Japanese paper, frosted glass, milky white plastic or the like so that light from a plurality of LEDs is mixed and diffused.
The light emitting unit is not limited to an LED, and may be an incandescent lamp, a fluorescent lamp, or the like. In the case of an incandescent lamp, the amount of light can be adjusted by controlling the voltage instead of the number of lighting.

The control device 7 calculates an activity index based on signals from the switching unit 4 and various sensors 5 and transmits the activity index to another control device 7. In addition, the control device 7 receives an activity index from another control device 7, calculates a display control amount for controlling the display device 6 based on the activity index, and performs display according to the display control amount. Make it.

The configuration of the control device 7 will be described with reference to FIG.

The control device 7 includes a switching unit I / F 71, a sensor I / F 72, a network I / F 73, a storage unit 74, and a weight setting operation unit 76 connected to the control unit 75.

The switching unit I / F 71 is an interface circuit that is connected to the switching unit 4 and inputs a manned signal and an unmanned signal to the control unit 75.

The sensor I / F 72 is an interface circuit that is connected to the various sensors 5 and inputs a detection signal to the control unit 75.

The network I / F 73 is an interface circuit that is connected to the network 3 and transmits / receives an activity index or the like.

The storage unit 74 is a memory device such as a ROM or a RAM, stores various programs and various data, and inputs / outputs these to / from the control unit 75. Various data includes a display table 741 and a weight table 742.

The display table 741 is a table in which the display control amount is associated with the display pattern by the display device, and is set in advance. The display pattern is represented by the number of LEDs to be lit and the ratio of the LED colors to be lit. The display control amount is calculated by the display control amount calculation means 753 as will be described later.
FIG. 4 illustrates the display table 741. For the display control amount 0, a display pattern of all extinction is set. Thereafter, as the display control amount is higher, a display pattern having a larger number of lightings, that is, a display pattern having a higher light amount (unit: lx (lux)) is set. In addition, a display pattern is set in which the higher the display control amount is, the higher the green and blue lighting ratio is and the lower the red lighting ratio is, that is, a display pattern having a higher color temperature (unit: K (Kelvin)). For example, when the activity index is 5, 19 LEDs are lit, of which 5 are red (28%), 7 are green (36%), and 7 are blue (36%).

The weight table 742 includes a movement score table 7421, a location score table 7422, and a building weight table 7423.
The movement score table 7421 is a table that associates human activities detected by the various sensors 5 with scores that serve as the basis of the activity index, and is set in advance.
The whereabouts score table 7422 is a table in which the whereabouts of people in the building detected by the various sensors 5 are associated with the score that is the basis of the activity index, and is set in advance.
The building weight table 7423 is a weight table of how much importance a particular family wants to specify and display a building in which another family lives, and the user appropriately sets a weight setting operation unit as described later. Set at 76 and store.

The activity index is calculated by collecting the scores by the activity index calculation means 751. Two types of scores are set: a movement score that focuses on people's movements and a location score that focuses on people's activities.

FIG. 5A shows a motion score table 7421, which is a table in which an elapsed time since the last detection signal is received and a motion score are associated with each other. The movement score is set to 3 points when the elapsed time is less than 5 minutes, 1 point at a time when 5 minutes and 7 minutes have passed thereafter, and 0 point when the elapsed time is 10 minutes or more.
The motion score is characterized in that it is weighted so as to become lower as the elapsed time becomes longer.

FIG. 5B shows a whereabouts score table 7422, which is a table in which the whereabouts of people determined by receiving detection signals from the respective illumination sensors are associated with the whereabouts scores. When the lighting sensor is detected from the lighting sensor installed in the bedroom, the location score is set to 1 point, similarly, 2 points for the bath, 3 points for the living room, and 1 point for the hallway. In addition, the location score when the lighting device is detected to be off is set to 0 regardless of the room because there is no human activity.
The whereabouts score is set in consideration of the activity that is performed exclusively in the room. For example, sleep is performed in a bedroom because the activity is low, and the lowest score is set. Hobby activities performed in the living room are set so that activity is high, and the highest score is set. Thus, the whereabouts score is characterized in that it is weighted according to the role of the room.

FIGS. 5C to 5E show a building weight table 7423, which is set for each building according to the familiarity with a family living in another building on the basis of a certain building. The weights to be set are set as 6 steps from a minimum of 0 to a maximum of 5.

For example, FIG.5 (c) is an example of the building weight table 7423 memorize | stored in the relief display unit (code | symbol 2a in FIG. 1) installed in the parents' house. As described above, the building b is an example of an apartment of a brother who is a single employee, and the building c is an apartment of a sister living alone.
As illustrated in FIG. 5 (c), although parents are already employed and independent sons, they are not so interested because they are worried about the activity status based on nutritional status etc. Not “3” is set for the building b. On the other hand, since the younger sister who lives alone always attracts great interest, the highest “5” is set in the building c.

FIG. 5D shows an example of the building weight table 7423 stored in the safe display unit (reference numeral 2b in FIG. 1) installed in the brother's apartment where the person is assigned.
As illustrated in FIG. 5D, for the son, there are some things that are age-related and the activity status based on the health condition of the parents is anxious, so “4” which is a high degree of interest is set for the building a. Has been. Also, “4”, which is a high degree of interest for the younger sister who lives alone, is set for the building c. In the example shown in FIG. 5D, the older brother has the same interest in the activity status of the parents and the younger sister.

FIG. 5E is an example of a building weight table 7423 stored in a safe display unit (reference numeral 2c in FIG. 1) installed in a condominium of a sister who lives alone.
As illustrated in FIG. 5E, the activity level based on the health condition of the parents is also worrisome for the daughter, so “3” is set as the interest level for the building a. On the other hand, “0”, which is almost indifferent, is set for the building b for the older brother who has been assigned alone.

As described above with reference to FIGS. 5C to 5E, a family living in one building sets and stores a weight value that reflects the degree of interest in the family living in another building. As described later, it can be reflected in the display state of the display device 6.

Returning to FIG. 3, each control device 7 is previously assigned an IP address capable of identifying the control device 7 in the network 3. In the storage unit 74, the IP address of the control device 7 of the communication partner is set in advance. The control device 7 of the communication partner is a control device 7 installed in a building where a partner who lives away from him / her lives. This IP address has a one-to-one correspondence with “building a”, “building b”, and “building c” in FIGS. 5C to 5E for each family who is a user. That is, it seems to the user that the building weight table 7423 is defined corresponding to each building, but the storage unit 74 stores the IP address of the control device 7 and the weight for each building correspondingly. Yes.
In addition, in the storage unit 74, the correspondence relationship between the sensor IDs of the various sensors 5 and the types of sensors, and the correspondence relationship between the sensor ID and the installation location (corresponding to the location of the person) for the illumination sensor are tabulated in advance. Is set. Hereinafter, this table is referred to as a sensor table (not shown).

The control unit 75 is an arithmetic unit such as a DSP or MCU, and reads a program describing the operations of the activity index calculation unit 751, the communication control unit 752, the display control amount calculation unit 753, the display control unit 754, and the like from the storage unit 74. And function as each means.
In addition, the control unit includes a timing unit (not shown), and can acquire the current time or use a timer.

The activity index calculation means 751 calculates the activity status of a person in the building as an activity index based on signals from the various sensors 5 and the switching unit 4, and outputs the calculated activity index to the communication control means 752.
Specifically, the activity index calculating means 751 calculates an activity index based on detection signals from various sensors 5 when receiving a manned signal from the switching unit 4 and receives an unmanned signal from the switching unit 4. In some cases, the activity index is set to the reference value (= 0).
Thus, since the activity index is used as the reference value when the building is unattended, an activity index exceeding the reference value is not calculated when the user goes out with the lighting device turned on. Therefore, it is possible to calculate and transmit an activity index that matches the actual situation of human activities in the building.

The calculation of the activity index based on the detection signals from the various sensors 5 is performed by selecting a score corresponding to each detection signal from each table of the weight table 742 and adding the selected scores. Whether or not the detection signal is a motion sensor can be determined by selecting a type corresponding to the sensor ID included in the received detection signal from the sensor table.

The selection of the motion score corresponding to the detection signal from the motion sensor will be described.
The activity index calculation means 751 stores the reception time in the storage unit 74 when a detection signal is received from the motion sensor, obtains the difference between the current time and the reception time as the elapsed time, and the motion score corresponding to the elapsed time Is selected from the motion score table 7421. Whether the detection signal is from the illumination sensor, and the location of the person whose illumination sensor has detected lighting are determined by selecting the type corresponding to the sensor ID included in the received detection signal and the installation location from the sensor table. it can.

As described above, since the movement score is set to be lower as the elapsed time is longer, the activity index is calculated so as to become lower with the elapse of time since the detection signal indicating the presence of human movement is received. Conversely, if the detection signal continues to be received in a short time interval, the activity index remains high because a high motion score continues to be selected.
Even if the motion sensor no longer detects a person's movement, in many cases, the person remains stationary and continues to act on the spot, and the movement is detected intermittently. Therefore, when the movement of a person is no longer detected, the activity index is not lowered immediately, but the activity index is gradually lowered with the passage of time, so that an activity index that matches the actual state of the person's activity in the building can be calculated and transmitted.

The selection of the whereabouts score corresponding to the detection signal from the illumination sensor will be described.
The activity index calculation means 751 stores the lighting state of the lighting device represented by the detection signal when the detection signal is received from the lighting sensor in the storage unit 74 for each lighting sensor, and the location corresponding to the lighting state of each lighting device. A score is selected from the whereabouts score table 7422.

Since the whereabouts score is set in the whereabouts score table 7422 as described above according to the activity for each whereabouts, the activity index is calculated to be higher as the person's activity is more active and lower as the person is less active.
Therefore, it is possible to calculate and transmit an activity index that matches the actual situation of human activity according to the location in the building.

When a new activity index is calculated by the activity index calculation unit 751, the communication control unit 752 transmits the calculated activity index to the communication partner control device 7 installed at a remote location via the network 3. . That is, the communication control means 752 outputs to the network I / F 73 a packet including the activity index calculated with the IP address of the control device 7 as the communication partner as the destination.
Further, the communication control means 752 receives the activity index from the control device 7 of the communication partner and outputs it to the display control means 754. That is, the communication control means 752 outputs the activity index acquired from the packet to the display control means 754 if the packet received by the network I / F 73 is unpacked and confirmed as a packet from the control device 7 of the communication partner.

The display control amount calculation unit 753 calculates a display control amount for determining a display pattern to be displayed on the display device 6 by the display control unit 754.
That is, the display control amount calculation unit 753 calculates the display control amount from the activity index of other buildings input from the communication control unit 752 with reference to the building weight table 7423.

The case of building a will be specifically described. It is assumed that 2 is transmitted as the activity index from the building b and 1 is transmitted as the activity index from the building c. The display control amount calculation means 753 refers to the building weight table 7423a, reads 3 which is the weight corresponding to the building b, reads 5 as the weight corresponding to the building c, and multiplies each by the transmitted activity index. Find a linear sum.
However, since the maximum value 5 of the display control amount is easily exceeded as it is, it is divided by 5 + 5 = 10, which is the sum of the maximum weights, and normalized so that it falls within the range of 0 to 5 and the display control amount. To do. That is, (2 × 3 + 1 × 5) /10=1.1 is the display control amount.

As another example, the case of building b will be specifically described. Assume that the activity index 5 is transmitted from the building a and the activity index 4 is transmitted from the building 3. The display control amount calculation means 753 refers to the building weight table 7423b, reads 4 which is the weight corresponding to the building a, reads 4 as the weight corresponding to the building c, and multiplies each by the transmitted activity index. A linear sum is obtained, divided by 10 which is the sum of the maximum weights, and normalized so as to be within a range of 0 to 5 as a display control amount. That is, (5 × 4 + 4 × 4) /10=3.6 is the display control amount.
Similarly, for the building c, the display control amount can be obtained by referring to the building weight table 7423c.

The display control unit 754 controls the display device 6 to display according to the display control amount calculated by the display control amount calculation unit 753. That is, the display control unit 754 selects a display pattern corresponding to the display control amount calculated by the display control amount calculation unit 753 from the display table 741, and outputs a control signal corresponding to the selected display pattern to the display device 6.

The weight setting operation unit 76 is an input unit realized by a touch panel. A combination of a numeric keypad and an LCD screen may be used.
A family who operates the safety display unit 2 provided in each building inputs weights based on intimacy with respect to families living in other buildings. In inputting, for example, the family of the building a inputs the weight according to the display message “Please input the weight for the building b”, and the control unit 75 stores the input weight in the building weight table 7423. When all other buildings have been entered, the setting is complete.

Note that instead of setting the building weight table 7423 based on the familiarity that the user thinks, other buildings may be set to reflect the number of family members living in the building. For example, 5 can be set in a building where 3 people out of a family of 6 live, 3 can be set in a building where 2 people live, and 1 can be set in a building where 1 people live. This may be input as one of the initial settings when the safety display system 1 is installed. As a result, there is an effect that it is possible to display with emphasis on the information of a building where a large number of people live.

Further, when the building weight table 7423 is set according to the number of people, it may be automatically set instead of the initial setting as described above. For example, referring to the outputs of the various sensors 5, the number of persons can be automatically counted from the average of daily output amounts, and can be set in the building weight table 7423 according to the number of persons. Accordingly, there is an effect that an elderly person who is not good at mechanical operation can display information with emphasis on information on a building where a large number of people live without complicated setting operations.

The display device 6 displays the degree of activity of other family members by reflecting the set weight with the difference in the amount of light and the color temperature. Without disturbing or invading the other party's privacy, you can casually display the status of family activities in remote buildings.

Further, since the display device 6 displays in three or more stages, changes due to human activities can be visually recognized, and it can be felt that a family is active in a remote building.
Furthermore, since the display pattern displayed on the display device 6 reflects the intimacy with respect to other families set according to the position of the family who visually recognizes it, the emphasis is particularly on families who want to display the activity status. The above feeling can be further enhanced.

Next, the operation of the safety display system 1 will be described with reference to FIG.

When activated, the control unit 75 of the control device 7 first initializes each unit and each means (S1). The activity index is initialized to zero. Also, an activity index update period (for example, 1 minute) is set and a timer is started. After the initialization, the control unit 75 repeatedly performs the processes of S2 to S10.

When the processes of S2 to S7 are executed, the control device 7 operates as a transmission-side control device, and periodically calculates and transmits a family activity index in the building where the control device is installed.

First, the activity index calculation means 751 of the control unit 75 confirms whether or not the detection signals from the various sensors 5 are received (S2), and if received, generates a reception record (S3). That is, if it is a detection signal from one of the motion sensors, the reception time (a common record regardless of the motion sensor) is stored in the storage unit 74, and if it is a detection signal from the illumination sensor, the detected state is lit. Is stored in the storage unit 74 for each illumination sensor.

Next, the activity index calculation means 751 confirms the arrival of the update time with reference to the timer (S4), and calculates the activity index if it has arrived (S5).

Details of the activity index calculation process will be described with reference to FIG.

First, the activity index calculating means 751 confirms the signal from the switching unit 4 (S50), and if the signal is an unmanned signal indicating an unmanned state, the activity index is set to a reference value of 0 (S51).
On the other hand, if the signal is a manned signal representing a manned state, the activity index calculation means 751 executes the processing of S52 to S63 and calculates the activity index according to the detection signals from the various sensors 5.

In S52 to S55, an activity index corresponding to the detection signal from the motion sensor is calculated.
That is, the activity index calculation means 751 confirms whether there is a motion sensor reception record in the reception record generated in S3 of FIG. 6 (S52). If there is a reception record, the activity index calculation means 751 calculates the difference between the current time and the reception time. The elapsed time is calculated (S53), and a motion score corresponding to the elapsed time is selected from the motion score table 7421 (S54). On the other hand, when there is no reception record, the activity index calculation means 751 sets the movement score to 0 (S55).

In S56 to S60, an activity index corresponding to the detection signal from the illumination sensor is calculated.
That is, the activity index calculation means 751 sets a loop process for the illumination sensor (S56, S60), and the illumination device in the corresponding room refers to the reception record generated in S3 of FIG. 6 for each illumination sensor. It is determined whether it is turned on or off (S57), a location score corresponding to the determination result is selected from the location score table 7422 (S58), and the selected location score is sequentially accumulated (S59).

When the processing is completed for all the sensors 5 in this way, the activity index calculating means 751 calculates the activity index by adding the accumulated value of the movement score selected in S54 and the location score calculated in S59 (S61). If the activity index calculated at this time exceeds the maximum value of 5 (S62-Yes), the activity index is corrected to 5 (S63).

Returning to FIG. 6, the activity index calculating means 751 of the control unit 75 stores the calculated activity index in the storage unit 74 (S6), and the communication control means 752 of the control unit 75 uses the calculated activity index as another building. (S7). The activity index is transmitted to the control device 7 of the communication partner via the network 3.

When the processes of S8 to S11 are executed, the control device 7 operates as a receiving side control device, and receives and displays the activity index calculated at the remote place.

That is, the display control amount calculation means 753 of the control unit 75 confirms whether an activity index is received from the control device 7 of the communication partner (S8), and if received, calculates the display control amount according to the received activity index. (S9).
Next, the display control means 754 selects a display pattern from the display table 741 according to the display control amount calculated by the display control amount calculation means 753 (S10), and displays a control signal corresponding to the selected display pattern on the display device. 6 (S11). The display device 6 lights the light emitting unit with a display pattern corresponding to the control signal.
