DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an occupancy display system suitable for an apartment house for the elderly.

[0002]

2. Description of the Related Art In a home for the elderly, it is necessary to unlock for emergency rescue. For this reason, an indication of whether or not a resident is indoors (ie, whether or not a resident is present) is a guide. In particular, when there are a plurality of residents in the same room, it is determined that the resident is absent (out of office) only by locking the external lock that locks the electric lock of the entrance door from the outside, and the absence display is displayed on the display device in the management room. That can make mistakes. To prevent such mistakes,
When one of the occupants goes out, the resident or the person who remains in the room performs a special occupancy operation (for example, an operation such as manually operating a push button switch or inserting a key into a predetermined place). In this case, the occupant status is displayed in the management room, and the occupancy display is performed by using the lock operation of the entrance door lock and the occupancy operation so as to avoid the mistake. A room display system is used.

[0003] This occupancy display system determines whether a resident is present or absent based on both an electric signal generated by locking the external lock and an electric signal generated by the special occupancy operation, thereby preventing an error. It was done.

[0004]

However, even in such a system, there is a case where the special occupancy operation is erroneously operated or forgotten, and the correct occupancy / absence display is performed. There was a problem that it was not possible. Therefore, an object of the present invention is to provide a system capable of correctly displaying an occupancy without being affected by an operation error or forgetting of an operation by a resident.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, an entrance lock is provided on an entrance door.

FIG. 1 is a block diagram of a first embodiment. Reference numeral 1 denotes an electric lock of an entrance door, and a signal is transmitted when an external lock is locked. 2
Is a push button switch provided in the room to perform the special operation in the room, and 3 transmits a flow signal according to the flow rate of the water supply with a water sensor. Reference numeral 4 denotes a circuit which receives a flow signal from the water sensor 3 and determines a temporal change of the flow signal, that is, a leak or a normal water use based on a water usage pattern. When there is a change in the amount of water used, it is determined that the occupant is occupied.When a certain amount of flow is continuously flowing, it is determined that there is water leakage. The occupancy signal is sent out, and otherwise the absence signal is sent out. When it is determined that a water leak has occurred, a water leak signal is transmitted.

Reference numeral 5 denotes a priority judging circuit. When an occupancy signal is transmitted from the judging circuit 4, the occupancy signal is transmitted to the display circuit 6 preferentially to display the occupancy. Reference numeral 7 denotes a display panel having a determination circuit 4, a priority determination circuit 5, and a display circuit 6. The display circuit 6 also displays a water leak in addition to the presence / absence display. FIG. 2 is an explanatory diagram of the second embodiment, which illustrates the second embodiment of the present invention in a view similar to a flowchart. In the figure, 1 is an electric lock of an entrance door, and 3 is a water sensor. The second embodiment is provided with the same push-button switch as the first embodiment, and determines the presence / absence of a room by judging signals from the electric lock 1, the water sensor 3, and the push-button switch 2. It is connected to a display panel equipped with software.

When the external lock of the electric lock 1 is locked (ON), an outside display (absence display) is displayed, and when the electric lock 1 is unlocked (OFF), an occupancy display is displayed. Further, when the push button switch 2 is manually operated (ON), the room display is displayed, and when the push button switch 2 is not operated, the outside display is displayed.
Further, when the water sensor is activated (0N) by the flow rate signal from the water sensor 3, the occupancy display and the non-operation (0N) are performed.
At the time of FF), the display is out. In addition, when the water sensor is operating, it means when the water is used intermittently,
When there is a change in the amount of water used, it is possible to determine the occupancy of the room from the living information based on such a water usage pattern.

In both of the above embodiments, the presence or absence of a room is determined from the water usage pattern. It is possible to determine the presence or absence of a room. As such living information, a gas use pattern, an electricity use pattern, or the like can be used. In both embodiments described above,
When the water sensor is operated by a certain amount during the absence display, there is provided program software for displaying the presence of a room in the room as a resident.

[0011]

Since the occupancy display system of the present invention is configured as described above, the presence / absence of the occupancy can be confirmed by the presence or absence of living information such as whether or not water is used for living. The correct occupancy display can be performed without operating an external lock or a special occupancy operation push button switch.
