Next, FIG. 6 is a system configuration diagram of the centralized monitoring supply control device according to the present invention, taking as an example the supply of tap water in pensions, apartments, condominiums, etc. This device consists of two centralized monitoring devices B, which are connected in parallel by a signal line C, and several individual supply control bags (hereinafter referred to as individual devices) A. 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.

The front panel 21 of the central monitoring device B is provided with lamps L1 to LIO (in the case of 10 houses) for displaying information on each residence, a buzzer sound stop switch SWI, a release switch SW2, and a buzzer BZI.

On the other hand, each individual device A has a display device Lll on its main body 22 that displays various data, information from the central monitoring device B, etc.
A card reader 23 which is a reading means, a card ejection switch SW3. Monitoring switch SW which is monitoring setting means
4. A water shutoff valve open indicator lamp L12 and a buzzer BZ2 are provided. The main body 22 also includes an electronic water meter 10 as shown in FIG.
are connected. The card reader 23 has a memory card (prepaid card) which is a portable storage medium.
25, the data stored therein can be read. The memory card 25 is purchased in advance by the user of each residence from the administrator or the like.

This stores data representing a certain amount of available water.

For example, it is assumed that a predetermined number of degrees are stored, with 1 cubic meter measured by the water meter 10 as one unit.

FIG. 7 shows the internal configuration of the centralized monitoring liquid MB and the individual device A.
It is equipped with cPU1. Power is supplied to the power supply terminal VDDI of the CPUI from a power supply circuit 26, and a switch detection circuit 27 is connected to the input port E1 to detect whether the switches SWI and SW2 are on or off. Also, CPU1
A lamp drive circuit 28 for driving the lamps L1 to LIO is connected to the output port 01 of. moreover,
A buzzer drive circuit 29 is connected to each output port 02 to cause the buzzer BZI to sound in the event of an abnormality. Furthermore, the signal line C is connected to the input/output boat l101.

On the other hand, the individual machine A is an information processing device CPt including a memory, etc.
Equipped with J2. Power is supplied to the power supply terminal VDD2 of the CPU 2 from a power supply circuit 30, a switch detection circuit 31 that detects on/off of the switches SW3 and SW4 is connected to the input port I2, and a power supply from the water meter 10 is connected to the input port I2. A water meter input circuit 32 for inputting the obtained message is connected. In addition, the output port 03 is connected to a water valve control circuit 3 that outputs opening/closing pulses to the water shutoff valve 24.
3. The output port 04 has a buzzer drive circuit 34 that drives the buzzer BZ2, the output port 05 has a display drive circuit 35 that drives the display Lll, and the output port 06 has a lamp drive circuit that lights the lamp L12. A circuit 36 is connected. Furthermore, the input/output port 1102 is connected to the input/output port 1101 of the CPUI via a signal line C, and the card reader 23 is connected to the input/output port 103.

In such a configuration, when the memory card 25 is inserted into the card reader 23, the CPtJ2
3, the degree stored in the memory card 25 is read out, and a signal is sent to the display drive circuit 35 to display the degree value on the display Lll. Further, 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 25 to the internal memory, and the stored power in the memory card 25 is rewritten by subtracting the power. That is, the CPU 2 decreases the storage number of the memory card 25 by one by using its data change function. At the same time, the CPU 2 controls the water shutoff valve control circuit 33.
The water cutoff valve 24 is opened, and the water cutoff valve open indicator lamp L12 is turned on by the lamp drive circuit 36. After this, turn on the card ejection switch SW3 and remove the memory card 25.
Even if the card reader 23 is removed from the card reader 23, 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 25 is O or is of a different type, the card reader 23 will eject the card without accepting it, and the display Lll will display that the card cannot be used.

In this case, the water shutoff valve 24 is not opened, and the water shutoff valve open indicator lamp L12 remains off.

When water is used with the water cutoff valve 24 open as described above, the water meter 10 integrates the measured value, and the contents of the message are read into the CPU 2 through the water meter input circuit 32. 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 10 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 25 is less than 1, that is, less than 1 cubic meter, the card reader 23 ejects the memory card 25, and the CPU 2 outputs a signal to the buzzer drive circuit 34 for several seconds to sound the buzzer BZ2, and the memory card 25 is ejected. Inform the user that the data has disappeared. At this time.

Display Lll shows the contents of the internal memory of CPU2 as 10.
Displayed in units of 0 liters. Furthermore, if you continue to use the water supply in this state, and when there are only 100 liters left in the internal memory, the buzzer drive circuit 34 will sound the buzzer BZ2 for several seconds, and if a new memory card 25 is not inserted,
The water shut-off valve 24 operates to alert the user that the water supply will be shut off. When a new memory card 25 is inserted, the contents of the internal memory are updated and can be used again.

By the way, if the user of a certain residence is an elderly person living alone, the monitoring setting switch SW4 of the individual device A is turned on. As a result, the internal timer of CPU2 starts operating,
A certain period of time (for example, 24 hours) after the monitoring setting switch SW4 is turned on or from the last change in the signal of the water meter input circuit 32 that inputs the message of the water meter 10.
When there is no change in the signal of the water meter input circuit 32, CP
U2 determines that there is an abnormality, and transmits the information from the input/output boat I102 to the CPU1 of the central monitoring device B using the information control function. In the central monitoring device B, at the same time, the lamp driving circuit 2B causes the lamp L1 to LIO corresponding to the residence of the individual device A to blink repeatedly.
A buzzer drive circuit 29 continues to sound a buzzer BZI to notify a manager or the like of which residence is experiencing an abnormality. The administrator confirms this and turns on the buzzer stop switch SWI to turn on the buzzer B of the central monitoring system fftB.
ZI can be stopped. Furthermore, after checking the residence where the abnormality was reported, turn on the release switch SW2 to reset the individual machine A of that residence,
Furthermore, the system continues to monitor residences whose monitoring setting switch SW4 is turned on.

Note that the monitoring setting switch SW4 may be provided in the central monitoring device B, and when the monitoring setting switch SW4 is set, the CPU
It monitors the changes in the signal and transmits the information to the central monitoring device B in the event of an abnormality.

Next, the processing performed by the individual machine A and the central monitoring device B will be explained according to the flowcharts shown in FIGS. 8 to 10. As shown in the flowchart of FIG.

On the other hand, if the memory card 25 is valid in step S54, the internal timer of the CPU 2 is cleared in step S57, and the water shutoff valve control circuit 33 is driven in step 858 to open the water shutoff valve 24.

Further, in step S59, the lamp drive circuit 36 is driven to light the water shutoff valve open indicator lamp L12, and in step S60, the frequency of the memory card 25 is read out and displayed.

Next, in step S61, it is determined whether the card ejection switch SW3 is turned on based on the signal from the switch detection circuit 31. If it is turned on, in step S62, the remaining amount is newly added to the memory card 25 by the card reader 23. After re-memorizing the data (frequency), step S63
eject the card.

When the card ejection switch SW3 is off in step S61, the process proceeds to step S64, where the water meter input circuit 32 reads the integrated value of the water meter 10 and imports the integrated data), and in step S65, the memory card 25
Determine whether the integrated value is the one for which frequency subtraction is performed. Here, if the frequency has not been subtracted, the process advances to step S66, and it is determined whether the monitoring setting switch SW4 is on based on the signal from the switch detection circuit 31. If it is off, the process returns to step S61, and if it is on, the next In step S67, it is determined whether the state in which the frequency is not subtracted continues for a set time. If the set time has elapsed, the CPU 2 of the individual machine A transmits the data to the central monitoring device B via the signal line C in step S68.
The abnormality information is transmitted to the CPU, and the process returns to step S61.

On the other hand, if the frequency is subtracted in step S65.

After subtracting the frequency read from the memory card 25 in step S69, the internal timer of the CPU 2 is cleared in step 570. Subsequently, in step S71, it is determined whether the remaining data on the memory card 25 has become less than 1 cubic meter, and when it has become less than 1 cubic meter, the buzzer drive circuit 34 is driven in step S72 to make the buzzer BZ2 sound for several seconds. After rewriting the remaining power on the card reader 23 in step S73, the memory card 25 is ejected in step S74.

In addition, it is determined in step S75 whether the remaining amount is 100 liters or less, and if the remaining amount is 100 liters or less, in step S76 the buzzer drive circuit 34 is driven to sound the buzzer BZ2 for several seconds, and in step S77 the display Lll A display prompting the user to insert a new memory card 25 is displayed.

Further, in step 878, it is determined whether there is no remaining usable amount, and when it is exhausted, in step S'79, the water shutoff valve control circuit 33 is driven to shut off the water shutoff valve 24, and at the same time, in step S80. After the water shutoff valve open indicator lamp L12 is turned off by the lamp drive circuit 36, the process returns to step S51.

Next, the operation when there is an interrupt from the centralized monitoring device B to the individual device A will be explained with reference to FIG.

A signal sent from the CPU of the central monitoring device B to the individual machine A via the signal line C is detected at the input/output port ■102, and in step S81 it is determined whether the signal is a release signal, and the signal is determined to be a release signal. If so, the internal timer of the CPU 2 is cleared in step S82. Further, in step S83, it is determined whether it is a monitoring setting signal, and if it is a monitoring setting signal, monitoring setting of the internal switch of the CPU 2 is performed in step s84.

Next, the operation of the central monitoring device B will be explained according to FIG. 1o. The signal from CPU2 of individual machine A is input/output port l1.
0f, it is determined in step S85 that the signal is an abnormal signal, and if it is an abnormal signal, in step S86 the central monitoring device B detects the one of the lamps L1 to LIO corresponding to the residence of the individual machine A. At the same time, in step S87, the buzzer drive circuit 29 is driven to sound the buzzer BZI.

If the signal from the switch detection circuit 31 is detected in step 388 and the buzzer sound stop switch SWI is turned on,
In step S89, the buzzer drive circuit 29 is driven to stop the buzzer BZI from sounding.
