Can be received. If the storage medium F or cash is not at hand, or if the storage medium F has a remaining storage amount of 0, the advance borrowing input by the advance borrowing input means allows a predetermined amount of payment to be supplied. In case of an emergency such as a fire, emergency input is performed by the emergency input means to provide emergency supply. In this way, the information control means J informs the centralized monitoring device A that the emergency input such as the pre-borrow input or the emergency input means has been made.

Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a system configuration diagram of the centralized monitoring and supply control device according to the present invention, which exemplifies tap water supply in a pension, an apartment, a condominium and the like. This device is composed of a centralized monitoring device A and a plurality of individual supply control devices (hereinafter, referred to as individual devices) B connected in parallel to the centralized monitoring device A by a signal line 10.
The centralized monitoring device A is installed in a place where an administrator or the like can easily operate, for example, in a management room, and the individual machine B is installed in each residence.

On the front panel 11 of the centralized monitoring device A, lamps L1 to L10 (for 10 units) that display information about each house, emergency switch SW1, buzzer sound stop switch SW2, release switch SW3,
A buzzer Bz1 is provided.

On the other hand, in each individual machine B, a display unit L11 for displaying various data, information from the centralized monitoring device A, etc. on its main body 12, a card reader 13 as a reading means, a card removal switch SW.
4, emergency switch SW5 which is an emergency input means, front borrowing switch SW6 which is a front borrowing input means, front borrowing indicator lamp L12,
A water shield valve open display lamp L13 and a buzzer Bz2 are provided, and the main body 12 is provided with an electronic water meter 14 as a supply amount detecting means.
And a water blocking valve 15 which is a supply path opening / closing means are connected.
The card reader 13 can read the data stored in these cards by inserting a memory card (prepaid card) 16 which is a portable storage medium or a clear card 17 which is a clearing means into the card reader 13. The memory card 16 is purchased in advance by the user of each residence from an administrator or the like, and stores data representing a certain amount of usable water supply. Incidentally, it is assumed that, for example, one cubic meter measured by the water meter 14 is set as one unit and stored at a predetermined frequency. The clear card 17 is stored by an administrator or the like, and stores specific data capable of resetting the individual machine B as described later.

FIG. 3 shows the internal configuration of the centralized monitoring device A and the individual machine B. Centralized monitoring device A is an information processing device CP including memory etc.
Comprising a U1, to the power supply terminal VDD1 of the CPU1 it is powered from the power supply circuit 18, the switch SW1 to the input port I _1, S
A switch detection circuit 19 for detecting ON / OFF of W2 and SW3 is connected. Further, the output port O ₁ lamp driving circuit 20 for driving the lamp L1~L10 to the CPU 1, and a buzzer drive circuit 21 for causing the ringing in an emergency the buzzer Bz1 are respectively connected to the output port O ₂ There is. Further, the signal line 10 is connected to the input / output port I / O ₁ .

On the other hand, the individual machine B comprises a processing unit CPU2, including memory, etc., the power supply from the power supply circuit 22 is supplied to the power supply terminal VDD2 of the CPU2, the input port I ₂ the switch SW4, SW5 in,
A switch detection circuit 23 for detecting ON / OFF of SW6 is connected, and a water meter input circuit 24 for inputting a message obtained from the water meter 14 is connected to the input port I ₃ . Further, the output port O ₂ outputs a pulse for opening and closing to the water blocking valve 15 to control the water blocking valve 25, the output port O ₄ displays a buzzer driving circuit 26 for driving the buzzer Bz 2, and the output port O ₅ displays Vessel L1
Display driving circuit 27 for driving the 1, the lamp drive circuit 28 for lighting the lamp L12 · L13 is connected to the output port O _6. Further, the I / O port I / O ₂ is connected to the I / O port I / O _{1 of the} CPU 1 via the signal line 10, and the I / O port I / O ₂
The card reader 13 is connected to O ₃ .

In such a configuration, when the memory card 16 is inserted into the card reader 13, the CPU 2 reads the frequency stored in the memory card 16 by the card reader 13 and sends a signal to the display drive circuit 27 to display the frequency. Display L11
To display. In addition, if frequency data is not stored in the internal memory of CPU2, the memory card 16 to 1
The degree of cubic meters is transferred to the internal memory, and the degree of that amount is subtracted to rewrite the memory of the memory card 16. That is, the CPU 2 decreases the storage frequency of the memory card 16 by 1 by the data changing function. At the same time, the CPU 2 causes the impermeable valve control circuit 25 to open the impermeable valve 15 and causes the lamp drive circuit 28 to turn on the impermeable valve open display lamp L13. After that, even if the memory card 16 is pulled out from the card reader 13 by turning on the card removal switch SW4, the data for one cubic meter is stored in the internal memory of the CPU2, so that the amount of water can be used. .

However, when the frequency of the memory card 16 is 0 or a card of a different type, the card reader 13 does not accept it and ejects the card, and the display L11 displays that the card cannot be used. In this case, the water cutoff valve 15 is not opened, and the water cutoff valve open display lamp L13 remains off.

As described above, when water is used with the water shut-off valve 15 open, the water meter 14 integrates the measured value, and the message contents are read by the CPU 2 through the water meter input circuit 24. Then, from the time when the data for one cubic meter is stored in the internal memory as described above, the data in the internal memory becomes 100 each time the water meter 14 integrates 100 liters.
The liters are subtracted, and the water supply can be used until the data becomes 0.

When the memory frequency of the memory card 16 is 1 or less, that is, when it is less than 1 cubic meter, the card reader 13 ejects the memory card 16, and the CPU 2 outputs a signal to the buzzer drive circuit 26 for a few seconds to make the buzzer Bz2 ring and the memory card 16
Notify the user that the data of is lost. At this time, the content of the internal memory of the CPU 2 is displayed on the display L11 in units of 100 liters. If you continue to use the water in this state and the internal memory content reaches 100 liters, the buzzer drive circuit 26 sounds the buzzer Bz2 for a few seconds, and if you do not insert a new memory card 16, the water blocking valve 15
Calls attention to the fact that the water supply will stop working. When a new memory card 16 is inserted, the contents of the internal memory are updated and can be used again.

However, when the data of the memory card 16 becomes 0 and the water blocking valve 15 works and the water supply cannot be used at midnight, etc., or when a new memory card 16 is not easily available, turn on the front borrowing switch SW6 to It can be used for cubic meters. That is, when the switch SW6 is turned on, one cubic meter worth of data is stored in the internal memory of the CPU 2 regardless of the card reader 13. At this time, the CPU 2 sends a signal to the lamp drive circuit 28 to turn on the front borrowing indicator lamp L12 and, at the same time, transmits the information from the input / output port I / O ₂ to the CPU 1 of the centralized monitoring device A by the information control function. . In the centralized monitoring device A, among the lamps L1 to L10, the lamp corresponding to the house of the individual machine B is turned on by the lamp drive circuit 20, and the manager is informed that the house is under rent.

Available memory card with data after pre-borrow input
When the card 16 is inserted into the card reader 13, the CPU 2 subtracts the frequency from the memory card 16 by the amount of the front loan. And CP
U2 stops the signal to the lamp drive circuit 28, turns off the front-lending-in-progress display lamp L12, and transmits the information that the front-lending is cleared to the centralized monitoring device A. In the centralized monitoring apparatus A, the lamp drive circuit 20 turns off the lamp.

Also, when there is no memory card 16 in each individual machine B and when it is necessary to use water urgently due to a fire or the like, when the emergency switch SW5 is turned on, the CPU 2 causes the water blocking valve control circuit 25 to block water. Since the valve 15 is forcibly opened, the user is free to use water. At this time, the CPU 2 sends a signal to the lamp drive circuit 28 to display the water shutoff valve display lamp L13.
At the same time, the signal is sent to the buzzer drive circuit 26 to make the buzzer Bz2 ring. Further, CPU 2 transmits information of CPU1 navel central monitoring apparatus A from the input and output ports I / O _2. As a result, in the centralized monitoring device A, the lamp L1 or
At L10, the lamp corresponding to the residence of the individual machine B is repeatedly blinked by the lamp drive circuit 20, and at the same time, the buzzer drive circuit 21 continues to ring the buzzer Bz1, and the administrator etc. operates the emergency switch SW5 at which residence. Notify you. By confirming this and turning on the buzzer sound stop switch SW2, the administrator or the like can stop only the buzzer Bz1 of the centralized monitoring apparatus A. Furthermore, when it becomes unnecessary to open the water blocking valve in an emergency, the centralized monitoring device A
By turning on the release switch SW3 in
With the information from 1, the buzzer Bz2 of the individual machine B can be automatically stopped via the CPU 2, and the water cutoff valve 15 can also be automatically closed and reset. The amount of water corresponding to the amount of water used in an emergency at the residence of the individual machine B is settled by inserting the usable memory card 16 into the card reader 13 and subtracting it from the memory card 16. If this is not done, the centralized monitoring device A determines that the payment has not been made by the CPU1 and the lamp L1
~ Flash the lamp corresponding to the house in L10,
In addition, the buzzer Bz1 is also sounded to notify the administrator etc. that it is uncleared.

On the other hand, when the administrator or the like discovers a fire or the like at some house, he / she can turn on the emergency switch SW1 of the centralized monitoring device A to freely use the water supply of another house. That is, when the emergency switch SW1 is turned on, the CPU1 transmits information to the CPU2 of all the individual machines B, and in the all individual machines B, the CPU2 opens the water blocking valve 15 regardless of whether the memory card 16 is inserted, Turn on the water shield valve open indicator lamp L13. At this time, in the centralized monitoring device A, all the lamps L1
~ L10 flashes and buzzer Bz1 also sounds to notify all houses of the emergency. Note that the stop and cancellation of the buzzer sound in this case are the same as above.

When a user leaves a house for moving or the like, an administrator or the like inserts a clear card 17 prepared in advance into the card reader 13 of the house. Then, the CP of the individual machine B
U2 resets itself according to the specific data stored in the clear card 17, clears the internal memory, etc., and shuts off the shutoff valve 15 by the shutoff valve control circuit 25 to initialize the individual machine B. Return to the state.
