〔Example〕

FIG. 1 shows a case where the washing water control device according to the present invention is applied to an in-building central control device installed in an intelligent building.

First of all, in the Intelligent Building, all visitors must enter the transponder card (TRC) shown in Figure 3 in advance.
It is mandatory to enter the museum with an ID card 12. The ID card 12 is made of a thin plate of synthetic resin, for example, and has a photograph 14 of the visitor affixed to its surface, and a field 16 for displaying the name of the affiliation, etc. corresponding to the photograph 14. A clip 18 is provided on the back side of the ID card 12 so that the ID card 12 can be attached to a chest pocket or the like.

This ID card 12 has a built-in circuit shown in FIG. It is determined whether the signal is a call signal for one's own ID card 12 or not, and when necessary, the notifying section 28 and the transmitting section 30 are activated to notify and transmit to the outside respectively. It's summery.

In addition, in this ID card 12, the calculation section 2 is
4 is not energized and the receiving section 26 receives a call signal from the outside, the power switching section 20 operates and the power supply section 22 operates the main circuit of the arithmetic section 24. By doing so, the life of the power supply unit 22 can be extended.

As an example, the power supply unit 22 can be a thin card-shaped battery having a structure in which two conductive plastic films are coated with manganese dioxide powder on one side and zinc powder on the other, stacked on top of each other with a non-woven fabric sandwiched between them. Furthermore, for the calculation section 24, the reception section 26, the notification section 28, and the transmission section 30, for example, an IC card having a built-in thin plastic IC device can be used.

The transmitter 30 is a plurality of ID cards 12 that are manufactured.
The notifying unit 28 can transmit a signal to identify itself, such as a different frequency for each unit, and the notifying unit 28
Different types of notification signals can be emitted depending on different types of received signals received at the terminal. for example
When transmitting a call signal to a visitor in possession of an ID card 12, the tone, frequency, signal cycle, etc. of the call signal to a specific room or the call signal to the building telephone can be changed depending on the type of call. All you have to do is control the output signal to the speaker so that the signal is emitted.

Now, in the flush water control device shown in FIG. 1, a urinal 44 is installed in the toilet 40, a urinal 46 is installed in the toilet 42, and on-off valves 48 and 50 are installed in the urinal 44 and the toilet 46, respectively. Only during cleaning, the on-off valves 48 and 50 are opened and cleaning water is supplied.

The on-off valve 48 and the on-off valve 50 are automatically controlled by a valve control device 52 and a valve control device 54, respectively.

Antenna 6 is installed on the ceiling of the toilets 40 and 42.
0 and 62 are attached so that a code signal transmitted from an ID card 12 carried by a person who enters the toilet 40 or 42 can be received.

In addition, in order to prevent the code signal transmitted from the ID card 12 from leaking to other rooms, the partition wall 5 of the room
8 and the door 56 are made of a material that blocks radio waves.

For example, the door 56 and the partition wall 58 may be coated with electromagnetic wave absorbing paint, or a mesh-like conductive cord may be embedded inside them. This prevents the code signal from leaking to other rooms.

The code signals received by the antennas 60 and 62 are sent to a radio device 64 that functions as a control signal transmitter.
(TRT). This radio device 64 is configured to also accept a code signal received from an antenna installed indoors in order to control the indoor air conditioning and the like.

In other words, the radio device 64 is connected to the in-house central control device.
Also used as TRT.

For this reason, in order to distinguish from which room the code signal input to the radio device 64 was transmitted, in this example, the input code signals from the plurality of antennas 60 and 62 are sequentially switched at a constant cycle. This switching is performed by a building management processor 72 that functions as a central control device, which will be described later.
(GP), it operates in synchronization with the discrimination cycle to discriminate the input code signal.

The code signal transmitted from the radio device 64 is sent to the central radio control device 70 (CRC) via the local radio control device 66 (LRC) and the local area network 68 (CAN).
This central wireless control device 70 sends the received code signal to a building management processor 72.

the above-mentioned local wireless control device 66;
The local area network 68, central wireless control device 70, and building management processor 72 all accept code signals to centrally manage the inside of the building, and send predetermined control signals to predetermined parts to perform predetermined control. It is also used as an in-house central control device.

Therefore, the data processed by the building management processor 72 can be sent to the display 7 as needed.
4. The data is supplied to the printer 76, where the data is displayed and printed out.

Furthermore, a distributed processing processor 80 (DDP) and an electronic exchange 82 (EPBX) are provided in connection with the central wireless control device 70, so that in an emergency or the like, commands from the building management processor 72 or the distributed processing processor 80 can be used. By controlling the electronic exchange 82 based on this, a designated telephone line can be secured.

A command signal for controlling the cleaning water sent from the building management processor 72 is sent to the building control remote station 84 via the central wireless control device 70 and the local area network 68.
(SRS), and a valve opening/closing control signal is sent to the corresponding valve control device 52 or valve control device 54. Therefore, by sending the valve opening/closing control signal, either or both of the valve control devices 52 and 54 are controlled, and flush water flows into the urinal 44 and the toilet 46 to clean the toilet bowl.

Note that this building control remote station 84 is also used as an in-house central management device, and air conditioners and the like are automatically controlled by control signals sent from the building control remote station 84.

FIG. 2 is a flowchart showing an example of the washing control of the washing water control device. In step a, reception is waited, and when the holder of the ID card 12 enters the toilet 40 or 42, the code signal is sent in step a. The presence or absence, and therefore the presence or absence, of entering the room is checked, and upon entering the room a code signal is received by antenna 60 or antenna 62.

As a result, the process moves to step b, where the time counter starts counting. Then, in step c, the presence or absence of the code signal is checked again, and the counting operation continues while the code signal is being received, and when the input of the code signal stops, the counted value (time) M and the set value (time) are checked in step b. The size of Mo is determined. Mo is set to about several tens of seconds, and M<
In case of Mo, proceed to step a without proceeding to step e.
Return to

When M≧Mo, proceed to step e to start cleaning, return to step a upon completion of cleaning,
The system enters the code signal reception waiting state again.

In this way, the size of M and Mo was determined in step d because there are cases where people enter the toilets 40 and 42 and immediately leave without fulfilling their duties, and in such cases, there is no need to wash. It is from.

〔Effect of the invention〕

The washing water control device of the present invention described above is used in intelligent buildings and the like. According to the present invention, most of the configuration of the in-house central control device can be used in configuring the wash water control device, so there is no need to install a dedicated wash water control device, and the scale of the device can be simplified. You can aim for

Additionally, since the status of toilet use can be monitored, the toilet bowl is flushed only when necessary, leading to water conservation and the effective use of resources.
