Sue” L-4 Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a system configuration diagram of a centralized monitoring and supply control device, taking as an example the supply of tap water in pensions, apartments, condominiums, etc. This device is composed of a central monitoring device A and a plurality of supply control devices (hereinafter referred to as individual devices) B according to the present invention connected in parallel to the centralized monitoring device A by signals 11iA1o. The centralized monitoring device A is installed in a place where it is easy for an administrator to operate, for example, in a management room, and the individual devices B are installed in each residence.

Central monitoring bag f! On the front panel 11 of A, there are lamps L1 to LIO (in case of 10 houses) that display information etc. of each house.
An emergency switch SWI, a buzzer sound stop switch SW2, a release switch SW3, and a buzzer Bz1 are provided.

On the other hand, each individual machine B has a display Lll on its main body 12 that displays various data, information from the central monitoring device A, etc.
A card reader 13 as a reading means, a card ejection switch SW4, an emergency switch SW5 as an emergency input means,
An advance borrowing switch SW6, which is an advance borrowing input means, an advance borrowing indicator lamp L12, a water shutoff valve open indicator lamp L13, and a buzzer Bz2 are provided. A water shutoff valve 15, which is an opening/closing means, is connected. When a memory card (prepaid card) 16 that is a portable storage medium or a clear card 17 that is a clearing means is inserted into the card reader 13, data stored in these cards can be read. Memory card 1
6 is purchased in advance by the user of each residence from the administrator, etc., and stores data representing a certain amount of usable water water. Incidentally, it is assumed that a predetermined number of degrees, for example, 1 cubic meter measured by the water meter 14 is stored as one unit. The clear card 17 is kept by an administrator or the like, and stores specific data that can be used to reset the individual machine B as described later.

FIG. 3 shows the internal configuration of the central monitoring device A and the individual devices B. Central monitoring device A is information processing device C including memory etc.
A power supply terminal VDDI of the CPU is supplied with power from a power supply circuit 18, and an input port is connected to a switch detection circuit 19 that detects whether the switches SWI, SW2, and SW3 are on/off. . Also, C.P.
A lamp drive circuit 20 for driving the lamps L1 to LIO is connected to the output port 01 of the UI, and a buzzer drive circuit 21 for making the buzzer Bz 1 sound in an emergency is connected to the output port 02. Further, the signal line 10 is connected to the input/output port I10□.

On the other hand, individual machine B has an information processing bag [CPU
2, the power supply terminal vDD2 of the CPU 2 is supplied with power from the power supply circuit 22, and the input port I2 is provided with the switches SW4. A switch detection circuit 23 for detecting ON/OFF of SW5 and SW6 is connected, and a water meter input circuit 24 for inputting a message obtained from the water meter 14 is connected to the five-person port. In addition, output port O1
A water shutoff valve control circuit 25 outputs opening/closing pulses to the water shutoff valve 15, and a buzzer drive circuit 26 that drives a buzzer Bz 2 is connected to the output port 04. Output port 05 has display Ll
A lamp drive circuit 28 for lighting the lamps L12 and Li2 is connected to the output port 06 of the display drive circuit 27 for driving the lamps L12 and Li2.

Further, the input/output port I/Ox is connected to the input/output port I10□ of the CPUI via the signal s1o.

The card reader 13 is connected to the input/output port l103.

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 1 display drive circuit 27 to display the degree value on the display LLI. Further, when the power data is not 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, CPU2 is
The data change function decreases the number of memories stored in the memory card 16 by one. At the same time, the CPU 2 causes the water shutoff valve control circuit 25 to open the water shutoff valve 15, and causes the lamp drive circuit 28 to turn on the water shutoff valve open indicator lamp L13. After this, even if you turn on the card ejection switch SW4 and pull out the memory card 16 from the card reader 13,
Since 1 cubic meter worth of data is stored in the internal memory of the CPU 2, that amount of water can be used.

However, if the power of the memory card 16 is O or a different type of card, the card reader 13 does not accept the card and spits out the card, and the 5 display Lll displays 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 also remains off.

As mentioned above, when water is used with the water cutoff valve 15 open, the water meter 14 integrates the measured value, and the contents of the message are read into the CPU 2 through the water meter input circuit 24. As mentioned above, from the time when data for 1 cubic meter is stored in the internal memory, the data in the internal memory is subtracted by 100 liters each time the water meter 14 integrates 100 liters, and that data is You will be able to use the water supply until

When the memory number 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 the memory card 16 from the buzzer drive circuit 2.
Output a signal to 6 for a few seconds to make buzzer Bz 2 sound,
The user is informed that the data on the memory card 16 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 Lll.

Furthermore, if the water supply continues to be used in this state, and when the internal memory has only 100 liters remaining, the buzzer drive circuit 26 will sound the buzzer Bz 2 for several seconds, and if a new memory card 16 is not inserted, the water cutoff valve 15 will be activated. warning that the water supply will be shut off due to the operation of the system. new memory card 16
By inserting a , the contents of internal memory are updated and can be used again.

However, when the data on the memory card 16 becomes 0 at night and the water shutoff valve 15 is activated, or when a new memory card 16 is not easily available, turning on the advance borrowing switch SW6 allows Cubic meters can be used. That is, when this switch SW6 is turned on, 1 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 controls the lamp drive circuit 2.
At the same time, the information control function sends a signal to the input/output port E 102 to turn on the advance borrowing indicator lamp L12.
The information is transmitted from the CPU 1 of the central monitoring device A to the CPU 1 of the central monitoring device A.

In the central monitoring device A, the lamp corresponding to the residence of the individual unit B among the lamp workers or LIO is connected to the lamp drive circuit 2.
o is turned on, and the manager etc. is informed that the residence is being rented in advance.

After inputting the advance loan, when a usable memory card 16 with data is inserted into the card reader 13, the CPU 2 subtracts the frequency of the advance loan from the memory card 16.

Then, the CPU 2 stops the signal to the lamp drive circuit 28, turns off the advance borrowing indicator lamp LL2, and transmits information that the advance debt has been cleared to the central monitoring device A. In the central monitoring device A, the lamp drive circuit 20 turns off the lamp.

In addition, when there is no memory card 16 in each individual machine B and there is an emergency need to use water due to a fire or the like, when the emergency switch SW5 is turned on, the CPU 2 shuts off water using the water shutoff valve control circuit 25. Since the valve 15 is forcibly opened, the user can freely use water. At this time, C
When the PU2 sends a signal to the lamp drive circuit 28 to turn on the water shutoff valve open indicator lamp L13, it also sends a signal to the buzzer drive circuit 26 to make the buzzer Bz2 sound. Further, the CPU 2 transmits the information to the CPUI of the central monitoring device A from the input/output port l102. As a result, in the centralized monitoring device A, the lamp drive circuit 20 causes the lamp drive circuit 20 to repeatedly blink the lamp corresponding to the residence of the individual unit B among the lamps L1 to LIO, and at the same time, the buzzer drive circuit 21 continues to sound the buzzer Bz1. A manager or the like is notified of which residence the emergency switch SW5 was operated in. The administrator or the like can stop only the buzzer Bz1 of the central monitoring device A by confirming this and turning on the buzzer sound stop switch SW2. Furthermore, when it is no longer necessary to open the water shutoff valve in an emergency, by turning on the release switch SW3 in the central monitoring device A, information from the CPUI is sent to the individual machine B via the CPU2.
automatically stops the buzzer Bz 2, and also shuts off the water shutoff valve 15.
can be automatically closed and reset. In addition, the individual machine B
To pay for the amount of water equivalent to the amount of water used in an emergency in one's residence, insert a usable memory card 16 into the card reader 1.
This is done by inserting into 3 and subtracting from it. If this is not done, the central monitoring bag HA will
It is determined that the payment has not been made due to I, and the lamp corresponding to the residence among lamps L1 to L10 is blinked, and the buzzer Bz
1 is also sounded to notify the administrator, etc. that the transaction has not yet been settled.

On the other hand, when an administrator or the like discovers a fire or the like in a residence, by turning on the emergency switch SW1 of the central monitoring device A, the water supply of other residences can be freely used. That is, when the emergency switch SWI is turned on, the CPUI transmits information to the CPU2 of all the individual machines B, and in all the individual machines B, the CPU2 opens the water shutoff valve 15 regardless of whether or not the memory card 16 is inserted. Turn on the water shutoff valve open indicator lamp L13. At this time, in the central monitoring device A, all the lamps L1 to LIO blink.

Buzzer Bz 1 also sounds to notify all residences of the emergency situation. In addition, to stop or cancel the buzzer sound in this case,
Same as above.

When a user leaves a certain residence for reasons such as moving, a manager or the like inserts a clear card 17 prepared in advance into the card reader 13 of the residence.

Then, the CPU 2 of the individual machine B performs a self-reset based on the specific data stored in the clear card 17, clears the internal memory, etc., and shuts off the water shutoff valve 15 using the water shutoff valve control circuit 25. , returns the individual machine B to its initial state.

FIGS. 4 and 5 are flowcharts of the processes of the CPUI and CPU2, respectively. The above operation will be explained as follows.

In FIG. 4, the CPU detects the state of the emergency switch SW1 with the switch detection circuit 19 in step S1, and if the switch SWI is on, transmits an emergency water shutoff valve opening request signal in step S2. Next, step S
3 drives the lamp drive circuit 20, and all lamps L1
~Turn on LIO. Further, in step S4, the buzzer drive circuit 21 is driven to make the buzzer Bz 1 sound.

On the other hand, when the emergency switch SWI is off in step S1, the process advances to step S5, and the buzzer sound stop switch SW2
The switch detection circuit 19 detects the state of the switch S.
If W2 is on, the buzzer drive circuit 21 stops sounding the buzzer Bz1 in step S6. If the buzzer sound stop switch SW2 is off in step S5, the process proceeds to step S7, where the switch detection circuit 19 detects the state of the release switch SW3, and if the switch SW3 is on, the process proceeds to step S8, where the emergency water cutoff Sends a valve release release request signal. Next, in step S9, the lamp drive circuit 20 is driven to turn off all the lamps L1 to LIO. Further, in step S6, the buzzer drive circuit 21 stops the buzzer Bz1 from sounding.

If the release switch SW3 is off in step S7, the process advances to step S10 and an information request signal is transmitted.

Next, in step Sll, a response signal transmitted from individual device B is received. Furthermore, the presence or absence of information is determined in step S12, and if there is no response information, the lamp drive circuit 20 is driven in step S9, and the individual machine B for which there is no response information
At the same time as turning off the lamp corresponding to
At this point, the buzzer drive circuit 21 stops the buzzer Bz 1 from sounding. On the other hand, if there is response information in step S12, the lamp drive circuit 20 is driven to light up all the lamps L1 to LIO in step S3, and the buzzer Bz 1 is made to sound by the buzzer drive circuit 21 in step S4. .

In FIG. 5, the CPU 2 first drives the display drive circuit 27 in step S13 to display a message on the display Li2 prompting the card to be inserted. Next, in step S14, it is detected whether or not a card is inserted into the card reader 13. If it is inserted, the process proceeds to step S15 to determine the validity of the card, and if it is invalid, the display is driven in step S16. The circuit 27 is driven to display on the display Lll that the card cannot be used, and the card is ejected from the card reader 13 in step s17.

On the other hand, if the card is valid in step 815, the process advances to step 818 to determine whether or not it is a clear card 17, and if it is the clear card 17, the process advances to step S19 to initialize the individual machine B. , step S2
0, the clear card 17 is ejected from the card reader 13.

If the clear card is not 17 in step 818.

That is, if the memory card 16 is valid, the process advances to step S21, where the water shutoff valve control circuit 25 opens the water shutoff valve 15. Next, in step S22, the lamp drive circuit 28
, and the water shutoff valve open indicator lamp L13 lights up to indicate that the water shutoff valve 15 has opened. Furthermore, step S23
The display driving circuit 27 is driven to display the frequency value of the memory card 16 on the display Lll.

Next, in step S24, the card ejection switch SW is
4 is on or not is detected by the switch detection circuit 23,
If it is on, the frequency of the memory card 16 is rewritten in step S25, and then the memory card 16 is ejected from the card reader 13 in step S26.

On the other hand, in step S24, the card ejection switch SW
4 is off, the process proceeds to step S27, where it is determined whether there is an information request signal from the central monitoring bag MA, and if so, the information is transmitted to the CPUI of the central monitoring device A at step S28.

Next, in step S29, the integrated value of the water meter 14 is taken in from the water meter input circuit 24, the amount used is calculated in step S30, and when it reaches 1 cubic meter, the frequency is subtracted in step S31. Subsequently, step S32
In step S33, it is determined whether the data in the memory card 16 is less than 1 cubic meter, and if it is, the buzzer Bz2 is made to sound for several seconds using the buzzer drive circuit 26.

Further, the frequency value of the memory card 16 is set to 0 in step S34, and the memory card 16 is ejected from the card reader 13 in step S35.

Furthermore, in step S36, it is determined whether the data in the internal memory of the CPU 2 has fallen below 100 liters, and when it has been cut off, in step S37, the buzzer Bz 2 is made to sound for several seconds by the buzzer drive circuit 26, and in step S38
The display driving circuit 27 is driven to display a message on the display Lll prompting the user to replace the memory card 16.

Next, in step S39, it is determined whether or not the data in the internal memory of the CPU 2 has become O. If there is data, the process returns to step S23, and if it is 0, the process proceeds to step 340, where the water shutoff valve control circuit 25 controls the water shutoff valve. At the same time, in step S41, the lamp drive circuit 28 is driven to turn off the water shutoff valve open indicator lamp L13.

If the memory card 16 is not inserted in step S14, the process proceeds to step S42, where it is determined whether or not the advance rental switch SW6 is on. If it is on, the individual machine B can be further borrowed in step S43. If it is possible, the process proceeds to step S44, where the lamp drive circuit 28 lights up the advance borrowing indicator lamp L12, and then the process proceeds to step S21.

If No in both step S14 and step S42, it is determined in step S45 whether there is an information request from the central monitoring device A, and if so, the information is transmitted from the individual device B to the central monitoring device A in step S46. do.

Further, in step S47, it is determined whether the mode is emergency mode, that is, whether the emergency switch SW5 is on for each individual aircraft, or whether there is an emergency water shutoff valve opening request signal from the central monitoring device ifA. , if YES, the water cutoff valve 15 is opened by the water cutoff valve control circuit 25 in step 548. Further, in step S49, the buzzer drive circuit 2
6, the buzzer Bz 2 is sounded, and the water shutoff valve open indicator lamp L13 is turned on in step S50.

Next, in step S51, it is determined whether there is an emergency water shutoff valve release request signal from the central monitoring system [A],
If so, the process proceeds to step S52, where the lamp drive circuit 28 turns off the water shutoff valve open indicator lamp L12, and
At step 853, the sound of the buzzer Bz 2 is stopped,
In step S54, the water shutoff valve control circuit 25 shuts off the water shutoff valve 15.

Note that the memory card 16 and the clear card 17 may be any portable storage medium such as a magnetic card or an IC card, and the storage format thereof does not matter.Also, cash can be inserted and the amount can be read. Therefore, the supply may be received in the same way as when the memory card 16 is inserted.

Furthermore, the device according to the present invention can be applied not only to tap water but also to supply control of electricity, hot water, gas, etc.

According to the present invention, even if you do not have a prepaid card type storage medium or cash, you can use it by inputting an advance loan. Even if data entered using a storage medium or cash remains, it can be erased and reset to the initial state.
