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

FIG. 2 is a system configuration diagram of a supply control device according to the present invention, which exemplifies tap water supply in a pension, an apartment, a condominium, and the like. The supply control device 10 includes a display unit L1 for displaying various data and the like on its main body 11, a card reader 12 as a reading unit, and a card removal switch SW.
1, an emergency switch SW2 which is an emergency input means, an impervious valve opening display lamp L2, an uncleared display lamp L3, and a buzzer BZ are provided. Further, to the main body 11, an electronic water meter 13 as a supply amount detecting means and a water blocking valve 14 as a supply path opening / closing means are connected. The card reader 12 can read the data stored in the card when a memory card (prepaid card) 15 which is a portable storage medium is inserted therein. The memory card 15 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. For example, it is assumed that one cubic meter measured by the water meter 13 is set as one unit and stored at a predetermined frequency.

FIG. 3 shows the internal structure of the supply control device 10. The supply control device 10 is an information processing device CPU including a memory and the like.
Is provided. Power is supplied from a power supply circuit 16 to a power supply terminal VDD of the CPU, and a switch detection circuit 17 for detecting ON / OFF of the card removal switch SW1 and the emergency switch SW2 is connected to the input port I1 and is connected to the input port I2. Is a water meter input circuit for inputting telegrams obtained from the water meter 13.
18 connected. In addition, the water blocking valve 14 is connected to the output port O1.
A shutoff valve control circuit 19 that outputs a pulse for opening and closing, a buzzer drive circuit 20 that drives the buzzer BZ to the output port O2, a display drive circuit 21 that drives the display L1 to the output port O3, and an output port O4 A lamp drive circuit 22 for lighting the lamps L2 and L3 is connected to the. In addition, input / output port I / O
The card reader 12 is connected to.

In such a configuration, when the memory card 15 is inserted into the card reader 12, the CPU reads the frequency stored in the memory card 15 by the card reader 12 and sends a signal to the display drive circuit 21 to display the frequency. Display on the display L1. Further, when the frequency data is not stored in the internal memory of the CPU, the frequency of 1 cubic meter is transferred from the memory card 15 to the internal memory, the frequency is subtracted and the memory of the memory card 15 is rewritten. That is, the CPU uses the data change function of the memory card 15
Decrement the memory frequency of by one. At the same time, the CPU opens the water cutoff valve 14 by the water cutoff valve control circuit 19 and turns on the water cutoff valve open display lamp L2 by the lamp drive circuit 22. After this,
Memory card 1 with card removal switch SW1 turned on
Even if the card 5 is pulled out from the card reader 12, the data for 1 cubic meter is stored in the internal memory of the CPU, so that the amount of water can be used.

However, when the frequency of the memory card 15 is 0 or a card of a different type, the card reader 12 does not accept it and ejects the card, and the display L1 displays that the card cannot be used. In this case, the water shield valve 14 is not opened, and the water shield valve open display lamp L2 remains off.

As described above, when water is used with the water shutoff valve 14 opened, the water meter 13 integrates the measured value and the content of the message is read into the CPU through the water meter input circuit 18.
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 is subtracted by 100 liters each time the water meter 13 integrates 100 liters, and the data becomes 0. Until that time, water can be used.

When the memory frequency of the memory card 15 is 1 or less, that is, when it is less than 1 cubic meter, the card reader 12 ejects the memory card 15, and the CPU outputs a signal to the buzzer drive circuit 20 for several seconds to cause the buzzer BZ to ring. At this time, display L1
Displays the contents of the CPU's internal memory in 100 liter units.

Furthermore, in this state, continue to use the water supply, and when the content of the internal memory reaches 100 liters, the buzzer drive circuit 20
Buzzes buzzer BZ for a few seconds and calls attention to the fact that if a new memory card 15 is not inserted, the water blocking valve 14 will work and the water supply will stop. When a new memory card 15 is inserted, the contents of the internal memory are updated and can be used again.

When the remaining amount is exhausted, the impermeable valve 14 is shut off and the impermeable valve open display lamp L2 is turned off.

By the way, when the memory card 15 is not at hand and the user has to use water urgently due to a fire or the like, the emergency switch SW2 is turned on. When this is turned on, the CPU drives the water blocking valve control circuit 19 to forcibly open the water blocking valve 14 by interruption. This allows the user to use water freely. At this time, the CPU sends a signal to the lamp drive circuit 22 to turn on the water blocking valve open display lamp L2, and also sends a signal to the buzzer drive circuit 20 to make the buzzer BZ ring.

The amount of tap water used at the time of emergency input is detected by the water meter input circuit 18 from the water meter 13 and stored in the internal memory of the CPU. Further, at this time, the CPU sends a signal to the lamp drive circuit 22 to blink the uncleared display lamp L3. The CPU counts the time after the user turns on the emergency switch SW2 with the internal clock, and the usage fee of tap water used in an emergency is cleared even after a certain time (for example, 48 hours) has elapsed. When it is judged that there is no
A signal is sent to the water blocking valve control circuit 19 to shut off the water blocking valve 14. When the user inserts the usable memory card 5 into the card reader 12 and clears the uncleared charge used in an emergency, the CPU sends a signal to the buzzer drive circuit 20 to stop the buzzer BZ from ringing. A signal is also sent to the lamp drive circuit 22 to turn off the uncleared display lamp L3. Further, when data remains in the cleared memory card 15, the CPU sends a signal to the water shutoff valve control circuit 19 to open the water shutoff valve 14 to enable normal use.

Needless to say, when the liquidation is performed within a fixed time (for example, within 48 hours), the normal use state is set. Further, the buzzer BZ may not be caused to ring at the same time when the emergency switch SW2 is turned on, but may be caused to ring after a certain period of uncleared time (for example, 48 hours) has elapsed.

Next, the processing performed by the CPU will be described with reference to the flowchart of FIG. Display drive circuit 21 in step S1
Is driven to display a message prompting the insertion of the memory card 15 on the display L1. Next, in step S2, the switch detection circuit 17 determines whether or not the emergency switch SW2 is turned on. If it is off, it is determined in step S3 whether the memory card 15 is inserted in the card reader 12, and if it is inserted, the validity of the memory card 15 is determined in step S4.
If it is invalid, the display drive circuit 21 is driven in step S5 to display the fact that it cannot be used on the display L1, and the memory card 15 is ejected from the card reader 12 in step S6.

On the other hand, if the memory card 15 is valid in step S4, the water blocking valve control circuit 19 is driven to drive the water blocking valve in step S7.
Open 14 Furthermore, in step S8, the lamp drive circuit
22 is driven to light the shutoff valve open display lamp L2, and the frequency of the memory card 15 is read and displayed in step S9.

Next, in step S10, it is determined from the signal from the switch detection circuit 17 whether or not the card removal switch SW1 is turned on. If it is turned on, in step S11 the card reader 12 newly sets the remaining amount in the memory card 15. After the data (frequency) is stored again, the card is ejected in step S12.

When the card removal switch SW1 is off in step S10, the process proceeds to step S13, the integrated value of the water meter 13 is read from the water meter input circuit 18 (the integrated data is taken in), and the frequency of the memory card 15 is subtracted in step S14. It is determined whether it is an integrated value. Here, when the frequency subtraction is reached, the frequency read from the memory card 15 is subtracted in step S15.

Next, in step S16, it is determined whether or not the remaining amount is less than 1 cubic meter. When the remaining amount is less than 1, the buzzer drive circuit 20 is driven and the buzzer BZ is rung for several seconds in step S17. Further, after the card reader 12 rewrites the remaining frequency of the memory card 15 in step S18, the memory card 15 is ejected in step S19, and the process returns to step S9.

Further, in step S20, it is determined whether the remaining amount is 100 liters or less, and when it is less than 100 liters, the buzzer drive circuit 20 is driven in step S21 to sound the buzzer BZ for several seconds, and in step S22, the display L1 A new memory card 1
Display a message prompting you to insert item 5.

Further, in step S23, it is determined whether or not the usable remaining amount is exhausted. When the remaining amount is exhausted, in step S24 the impervious valve control circuit 19 is driven to shut off the impervious valve 14, and in step S25 the lamp drive circuit. After turning off the water shield valve open display lamp L2 by 22, the process returns to step S1.

Next, an operation in an emergency when the emergency switch SW2 is turned on will be described. If the emergency switch SW2 is turned on in step S2, the process proceeds to step S26 to drive the buzzer drive circuit 20 to ring the buzzer BZ. Next, in step S27, the water cutoff valve control circuit 19 is driven to open the water cutoff valve 14. Further, in step S28, the lamp drive circuit 22 is driven to turn on the water shield valve open display lamp L2. In the next step S29, the meter reading data of the water meter 13 is fetched through the water meter input circuit 18, and the usage frequency after the emergency switch SW2 is turned on in step S30 is driven by the indicator drive circuit 21. In addition to displaying on the display L1, the lamp drive circuit 22 is driven to blink the uncleared display lamp L3.

In the next step S31, it is determined whether or not the memory card 15 is inserted into the card reader 12, and if not, the process proceeds to step S32 to count the time. Here the CPU
If the memory card 15 is not inserted into the card reader 12 even after the predetermined time has elapsed, the water cutoff valve control circuit 19 is driven to cut off the water cutoff valve 14 in step S33. .

Next, in step S34, the validity of the memory card 15 is determined, and if it is invalid, in step S35 the display driver circuit 21
Is displayed on the display L1 and the memory card 15 is read by the card reader 1 in step S36.
It is discharged from step 2, and the process returns to step S29.

On the other hand, if it is valid, the process proceeds to step S37 and the water meter 1
The meter reading data of 3 is fetched through the water meter input circuit 18, and the usage frequency after the emergency switch SW2 is turned on is subtracted from the memory card 15 by the card reader 12 in the next step S38. In the next step S39, it is determined whether the used frequency is subtracted from the memory card 15,
If the subtraction cannot be completed, the process proceeds to step S36. When the subtraction is completed, the process proceeds to step S40, the lamp drive circuit 22 is driven, and the uncleared display lamp L3 is turned off. Further, in step S41, the buzzer drive circuit 20 is driven to stop the ringing of the buzzer BZ, and then the process proceeds to step S7. Step
The operation after S7 is as described above.

Note that the memory card 15 may be any portable storage medium such as a magnetic card or an IC card, and the storage form does not matter. Alternatively, cash may be inserted and the amount of money may be read, so that the same supply as when the memory card 15 is inserted may be received.

Further, the device according to the present invention is not limited to tap water, electricity,
It can also be applied to supply control of hot water and gas.

EFFECTS OF THE INVENTION According to the present invention, tap water or the like can be supplied in an emergency even if a storage medium is not at hand and cash is absent, and after the emergency situation, the usage fee used in the emergency is settled for a certain time or more. If not done, the supply can be forcibly stopped to prevent unauthorized use.
