FIG. 2 is a system configuration diagram of a centralized monitoring and supply control device that takes as an example the supply of tap water in pensions, apartments, condominiums, etc. This device is composed of a central monitoring device MB and a plurality of individual supply control devices (hereinafter referred to as individual devices) A connected in parallel to the central monitoring device MB via a signal line 10. The central monitoring device B is installed in a place where it can be easily operated by a manager or the like, for example, in a management room. Individual machine A is installed in each residence.

On the front panel 11 of the central monitoring device B, residence lamps L1 to LIO corresponding to each individual supply control device (each residence) A are provided.
(In the case of 10 units), a display L11. that displays information from the individual supply control device A. Input key for inputting house number, clear information, etc. - 3WI, buzzer sound stop switch SW
2. A release switch SW3 and a buzzer BZI are provided. Also, a central monitoring control device! ! A fire detector M is connected to B via a signal line 10.

On the other hand, each individual machine A has a display L12 on its main body 12 that displays various data, information from the central monitoring device B, etc.
A water shutoff valve open indicator lamp L13, a card reader 13 serving as reading means, a card ejection switch SW4, and a buzzer BZ2 are provided.

Further, connected to the main body 12 are an electronic water meter 14 as a supply amount detection means and a water shutoff valve 15 as a supply path opening/closing means. When a memory card (prepaid card) 16, which is a portable storage medium, is inserted into the card reader 13, the data stored in the card can be read. The memory card 16 is purchased in advance by the user of each residence from the administrator or the like. For example, it is assumed that 1 cubic meter measured by the meter 14 is stored as a predetermined number of degrees.

FIG. 3 shows the internal configuration of the centralized monitoring system [B and individual equipment A. Central monitoring device B is information processing device C including memory etc.
Equipped with PUI. Power is supplied to the power supply terminal VDDI of the CPUI from the power supply circuit 17, an external input detection circuit 18 for detecting external input from the fire detector M is connected to the input port 1, and an input port 12 is connected to the input port 1. Oysters-5W
A switch detection circuit 19 is connected to detect the on/off state of I and the switches SW2 and SW3. Also, CPU
The output port 01 of I is a lamp drive circuit 20 for driving the lamps L1 to LIO, the output port 02 is a display drive circuit 21 for driving the display Lll, and the output port 03 is a buzzer BZI that sounds. A buzzer drive circuit 22 is connected to each. Further, the signal line 10 is connected to the input/output port l101.

On the other hand, individual machine A is an information processing device CPU including memory, etc.
2. Power is supplied to the power supply terminal VDD2 of the CPU 2 from a power supply circuit 23, a switch detection circuit 24 that detects whether the switch SW4 is turned on or off is connected to the input port 3, and the input port 4 receives power from the water meter 14. A water meter input circuit 25 for inputting a message sent is connected. Further, the output port 04 has a water shutoff valve control circuit 26 that outputs opening/closing pulses to the water shutoff valve 15, and the output port o5 has a buzzer drive circuit 2 that drives a buzzer BZ2.
7. The display drive/drive circuit 28 that drives the display L12 is connected to the output port 06, and the lamp L13 is connected to the output port o7.
A lamp drive circuit 29 for lighting is connected. Furthermore, the input/output port l102 is connected to the CP via the signal line 10.
It is connected to the input/output port 1101 of the UI, and the card reader 13 is connected to the input/output port 103.

In such a configuration, when the memory card 16 is inserted into the card reader 13, the CPU 2
3 reads out the degree stored in the memory card 16, and sends a signal to the display drive circuit 28 to display the degree value on the display L12. Furthermore, when no power data is stored in the internal memory of the CPU 2, the power for 1 cubic meter is transferred from the memory card 16 to the internal memory, and the stored power in the memory card 16 is rewritten by subtracting the power. That is, the CPU 2 decreases the storage number of the memory card 16 by one by using its data change function. At the same time, the CPU 2 controls the water shutoff valve control circuit 26.
The water cutoff valve 15 is opened, and the water cutoff valve open indicator lamp L13 is turned on by the lamp drive circuit 29. After this, turn on the card ejection switch SW4 and remove the memory card 16.
Even if the card reader 13 is removed from the card reader 13, the data for 1 cubic meter is stored in the internal memory of the CPU 2, so that amount of water can be used.

However, if the power of the memory card 16 is O or it is a different type of card, the card reader 13 will eject the card without accepting it, and the display L12 will display that the card cannot be used.

In this case, the water shutoff valve 15 is not opened, and the water shutoff valve open indicator lamp L13 remains off. .

When water is used with the water cutoff valve 15 open as described above, the water meter 14 integrates the measured value.

The contents of the message are sent to the CPU through the water meter input circuit 25.
2. Then, from the time when the data for 1 cubic meter is stored in the internal memory as described above, the data in the internal memory is subtracted by 100 liters each time the water meter 14 integrates 100 liters, and the data becomes 0. You will be able to use the water supply until the end of the year.

When the memory count of the memory card 16 is less than 1, that 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 27 for several seconds to make the buzzer BZ2 sound, and the memory card 16 is ejected. Inform the user that the data has disappeared. At this time, the contents of the internal memory of the CPU 2 are displayed in units of 100 liters on the display L12. moreover,
If you continue to use the water supply in this state, the contents of the internal memory will remain at 1.
When the water reaches 00 liters, the buzzer drive circuit 27 makes the buzzer BZ2 sound for several seconds to alert the user that if a new memory card 16 is not inserted, the water shutoff valve 15 will operate and the water supply will be shut off. When a new memory card 16 is inserted, the contents of the internal memory are updated and can be used again.

When a user leaves a certain residence due to moving etc., when the administrator etc. inputs the residence number using the input key-8WI of the central monitoring device B (the input is detected by the switch detection circuit 19), the CPU is connected to the individual machine A via the signal line 10.
The data stored in the internal memory of the CPU 2 is read out, and the contents are displayed on the display Lll. Therefore, when an administrator or the like inputs clear information from input key 8W1.

The CPUI is connected to the CPU 2 of the individual machine A via the signal line 10.
control. In this case, when the memory card 16 is inserted into the card reader 13, the CPU 2 clears the data stored therein or ejects the memory card 16 from the card reader 13 without clearing it.

At the same time, the CPU 2 clears the internal memory and shuts off the water shutoff valve 15 using the water shutoff valve control circuit 26, returning the individual machine A to its initial state.

In addition, when a fire occurs in a residence and the fire detector M is activated, the external input detection circuit 18 of the central monitoring device B is activated.
detects the fire signal. In this case, the CPUI transmits the information to the CPU 2 of all the individual machines A, and in all the individual machines A, the water shutoff valve control circuit 26 forcibly opens the water shutoff valve 15 regardless of the presence or absence of the memory card 16. , the water shutoff valve open indicator lamp L1 is activated by the lamp drive circuit 29.
3 is lit, and at the same time, the buzzer BZ2 is sounded by the buzzer drive circuit 27 to notify all the residences of the emergency situation. At this time, in the central monitoring device B, all lamps L
1~LIO flashes and the buzzer BZI also sounds. An administrator or the like can stop the buzzer BZI of the central monitoring device B by turning on the buzzer sound stop switch SW2.

Furthermore, when the operation of the fire detector M has stopped and there is no longer a need to open the water shutoff valve, by turning on the release switch SW3 in the central monitoring device B, information from the CPUI is sent to the individual devices via the CPU2. The buzzer BZ2 of A can be automatically stopped, and the water shutoff valve 15 can also be automatically closed and reset. Note that the amount of water equivalent to the amount of water used in an emergency at the residence of individual machine A is paid by inserting a usable memory card 16 into the card reader 13 and subtracting the amount from the amount. If this is not done, the CPU 1 of the central monitoring device B determines that the payment has not been made, flashes the lamp corresponding to the residence among the lamps L1 to LIO, and also sounds the buzzer BZ1, informing the administrator that the payment has not been made. Let me know something.

Next, the processing performed by the nine individual machines A and the central monitoring device B will be explained according to the flowcharts shown in FIGS. 4 to 8.

Determine whether the integrated value is the one to perform. If the number of degrees is subtracted by one, the number of degrees read out from the memory card 25 is subtracted in step S65. Next, step 86
In step S67, it is determined whether the remaining amount is less than 1 cubic meter, and if it is, in step S67, the buzzer drive circuit 27 is driven to make the buzzer -BZ2 sound for several seconds. Furthermore, in step 868, the memory card 1 is read by the card reader 13.
After rewriting the remaining power of 6, the memory card 16 is ejected in step S69.

In step S70, it is determined whether the remaining amount is 100 liters or less, and if the remaining amount is 100 liters or less, in step S71, the buzzer drive circuit 27 is driven to sound the buzzer BZ2 for several seconds, and in step S72, the display L12 is activated. A display prompting the user to insert a new memory card 16 is displayed.

Further, in step S73, it is determined whether there is no remaining usable amount, and when it is exhausted, in step S74, the water shutoff valve control circuit 26 is driven to shut off the water shutoff valve 15, and at the same time, in step S75, the lamp drive circuit After turning off the water shutoff valve open indicator lamp L13 by step S5

On the other hand, if the clear signal is selected in step S84, the process advances to step 888, and a clear signal is transmitted from the CPU to the individual machine A via the signal line 10. As a result, the internal memory of the CPU 2 of the individual machine A to which the information was transmitted is cleared as described above.

Next, the operation in the case of fire detection will be explained with reference to FIG. When a fire signal is transmitted from the CPU of the central monitoring device B to the CPU 2 of the individual machine A via the signal line 10, the water cutoff valve control circuit 26 is driven in step 889 to close the water cutoff valve 15.
At the same time, the buzzer drive circuit 27 causes the buzzer BZ2 to sound, and in step S90, the lamp drive circuit 29 is driven to light the water shutoff valve open indicator lamp L13. In the next step S91, reception is waited until a release signal is transmitted from the CPU of the central monitoring device B to the CPU 2 of the individual device A via the signal line 10. Here, when the release signal is received, the process proceeds to step S92, where the lamp drive circuit 29 turns off the water shutoff valve open indicator lamp L12, and stops the buzzer BZ2 from sounding.
Subsequently, in step S93, the water cutoff valve control circuit 26 shuts off the water cutoff valve 15, and the process returns.
