The switching unit 4 is operated by a user of the building when going out and returning home, and outputs a manned signal when switched to the manned state and outputs an unmanned signal when switched to the unmanned state. In the example of FIG. 2, the switching unit 4 is installed near the entrance of the building.
In addition, the security device provided with the mode switch which switches security mode (unmanned state) and security cancellation | release mode (manned state) can also be utilized as the switch part 4. FIG.
Further, it may be switched automatically by determining whether the building is manned or unmanned using a sensor or RF tag for detecting the presence or absence of a person.

The various sensors 5 are sensors that detect human activities in the building and output detection signals. The various sensors 5 are installed in each room and detect a person's activity status such as the presence / absence of a person's activity and the location of the person. The various sensors 5 are preliminarily assigned sensor IDs that can be individually identified in the safety display unit 2, and the various sensors 5 output their detection signals including their own sensor IDs.
In the figure, “M” is a motion sensor that detects the movement of a person. Each motion sensor is composed of an infrared sensor, a microwave sensor, or the like, and outputs a detection signal when a human motion is detected.
In the figure, “L” is an illumination sensor that detects turning on / off of the illumination device installed in the building. Each illumination sensor is composed of an illuminance sensor or a current detector, and outputs a detection signal when the lighting device is turned on or off.
In the example of FIG. 2, the motion sensor is installed in the entrance, bedroom, living room, and dressing room, and the illumination sensor is installed in the entrance, bedroom, living room, and bath.

The display device 6 is a device that displays a state of human activity in a remote building so that a person can recognize it. 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 the signals from the switching unit 4 and various sensors 5 and transmits it to the other control device 7, receives whether display is possible for the transmission as a display completion signal, and according to the contents Display the contact reminder. The control device 7 receives the activity index from the other control device 7 and controls the display device 6 to display according to the activity index.

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, a notification unit 76, and an operation unit 77 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, a display completion signal, and 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. The various data includes a display table 741, a weight table 742, and a current building state (not shown).

The display table 741 is a table in which the activity index 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.
FIG. 4 illustrates the display table 741. For the activity index 0, a display pattern of all extinctions is set. Thereafter, a display pattern with a larger number of lightings, that is, a display pattern with a higher light quantity (unit: lx (lux)) is set as the activity index is higher. Further, a display pattern is set in which the higher the activity index is, the higher the green and blue lighting ratios and the smaller the red lighting ratio, that is, the higher the color temperature (unit: K (Kelvin)). For example, when the activity index is 5, 19 LEDs are lit, and among them, the display pattern is 5 (28%) red, 7 (36%) green, and 7 (36%) blue.

The weight table 742 is a table in which human activities detected by the various sensors 5 are associated with scores serving as the basis of the activity index, and are set in advance. 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 is a table in which the elapsed time since the last reception of the detection signal from the motion sensor is associated with the motion score. 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 is a table in which a whereabouts of a person determined by receiving a detection signal from each illumination sensor is associated with a whereabouts score. 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 service of the room.

Moreover, the memory | storage part 74 memorize | stores the present building state, and if a manned signal is received from the switching part 4, it will be set to a manned state, or if an unmanned signal is received, a setting will be updated to an unmanned state.

Each control device 7 is previously given an IP address that can identify 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.

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 notification unit 76 displays a message prompting the user of the building to contact the communication partner. For example, it is indicated by lighting of a liquid crystal screen, a dedicated pictogram, and a dedicated LED.

The operation unit 77 is a switch for canceling the display that prompts the user to contact the communication partner displayed on the notification unit 76. The user of the building confirms the contact reminder display displayed on the notification unit 76 and contacts the communication partner displayed on the notification unit 76 when he / she does not want to contact the communication partner. When it is desired to cancel the display prompting the user, the operation unit 77 is operated.

The control unit 75 is an arithmetic unit such as a DSP or MCU, and stores programs describing the operations of the activity index calculation unit 751, the communication control unit 752, the display control unit 753, the contact prompting unit 754, the notification release unit 755, and the like. It functions as each means by reading from 74 and executing.
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 the weight table 742 and adding the selected scores.

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 weight table 742. 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.

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 weight table 742. 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, because the whereabouts score corresponding to the activity for each location is set in the weight table 742, the activity index is calculated to be higher as the activity of the person is more active, and lower as the activity 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 753. That is, the communication control means 752 outputs the activity index acquired from the packet to the display control means 753 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.

Further, the communication control means 752 transmits the generated display completion signal to the communication partner control apparatus 7 installed in the remote place via the network 3 when the display completion signal is generated by the display control means 753. To do. That is, the communication control means 752 outputs to the network I / F 73 a packet containing a display completion signal generated with the IP address of the control device 7 as the communication partner as the destination.

Further, the communication control means 752 receives a display completion signal, which is a response to the transmitted activity index, from the communication partner control device 7 and outputs it to the contact prompting means 754. That is, when the communication control means 752 unpacks the packet received by the network I / F 73 and is confirmed as a packet from the control device 7 of the communication partner, the communication control means 752 outputs a display completion signal acquired from the packet to the communication prompting means 754. .

The display control means 753 controls the display device 6 to display according to the received activity index. That is, when the current building state of the storage unit 4 is a manned state, the display control unit 753 selects a display pattern corresponding to the activity index input from the communication control unit 752 from the display table 742, and displays the selected display pattern. A corresponding control signal is output to the display device 6.
As described above, the display device 6 displays the difference in the activity index by the difference in the light amount and the color temperature, and therefore, unlike the blinking light, the sound, and the image, it attracts excessive attention, disturbs the life, and infringes on the other party's privacy. You can casually display the status of human 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 person is active in a remote building.

In addition, the display control means 753 receives the result of the display control from the display device 6 and combines it with the current building state of the storage unit 4, such as “Unmanned state”, “Manned state / display success”, “Manned state / display failure”, etc. A display completion signal is generated.

The contact reminder 754 displays the notification unit 76 in accordance with the received display completion signal. That is, the contact reminder 754 determines that the display completion signal is not received within a predetermined time from the communication controller 752 or the display completion signal input from the communication controller 752, and the communication partner is in a manned state. When the display fails, the notification unit 76 is urged to contact the communication partner.

If the display completion signal cannot be received within a predetermined time, it is suspected that the communication partner control device 7 is out of order. In addition, even if the display completion signal is received, if the content is that the display has failed in the manned state, a failure of the display device 6 is suspected. Therefore, the information can be displayed on the notification unit 76, and the communication with the communication partner can be positively promoted by taking an equipment failure as an opportunity.

When the operation unit 77 is operated by a user of the building, the notification canceling unit 755 cancels the display that prompts the user to contact the communication partner whose display has been held in the notification unit 76 until then.

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 S11.

When the processes of S2 to S9 are executed, the control device 7 operates as a transmission-side control device, and periodically calculates and transmits a human 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 weight table 742 (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 weight table 742 (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 to control the communication partner. It transmits to the apparatus 7 (S7). The activity index is transmitted to the control device 7 of the communication partner via the network 3. And the reception time of the display completion signal with respect to the transmitted activity index is set, the timer is started (S8), and the contact reminder control is performed (S9).

Details of the contact reminder control process will be described with reference to FIG.

With reference to the timer set in S8, the arrival of the reception time of the display completion signal is confirmed (S91). If it has arrived (S91-Yes), the display completion signal has not been received within the predetermined time. If it is a manned state (S92-Yes), a notice of contact is displayed on the notification unit 76 (S93).
If the display completion signal is received within a predetermined time (S94-Yes), the display completion signal is determined (S95, S96), and the received display completion signal is “manned state / display failure” and the communication partner is displayed in the manned state. If it is unsuccessful (S96—Yes, “Manned / Failed”), and if it is manned (S92—Yes), a notification reminder is displayed on the notification unit 76 (S93). When the received display completion signal is “unmanned state” and “manned state / successful display”, the processing is terminated without displaying the notification prompt on the notification unit 76.

Returning to FIG. 6, when the processing of S10 to S11 is executed, the control device 7 operates as a receiving side control device, and receives and displays the activity index calculated in the remote place.

That is, the display control means 753 of the control unit 75 confirms whether or not an activity index is received from the control device 7 of the communication partner in the manned state (S10), and if received, corresponds to the received activity index. The display is controlled (S11).

Details of the display control process will be described with reference to FIG.

First, the current building state in the storage unit 4 is referred to confirm whether it is manned (S111). If it is manned (S111-Yes), a display pattern is selected from the display table 741 (S112). Then, a control signal corresponding to the selected display pattern is output to the display device 6 (S113). The display device 6 turns on the light emitting unit with a display pattern corresponding to the control signal, and outputs the display result to the display control means 753. When the display result obtained from the display device 6 is successful (S114—Yes), the display control means 753 stores “manned state / display success” in the storage unit 74 as a display completion signal (S115). When the display result obtained from the display device 6 is not successful (S114-No), “manned state / display failure” is stored in the storage unit 74 as a display completion signal (S116). On the other hand, in the case of the unattended state (S111-No), the “unmanned state” is stored in the storage unit 74 as the display completion signal (S117).

The communication control means 752 of the control unit 75 transmits a display completion signal to the communication partner control device 7 (S118).

In the above embodiment, the example which performs a contact reminder display when both the transmission side control apparatus and the receiving side control apparatus are manned states was shown.
