Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card system for providing goods, services and the like by means of an IC card. Specifically, it identifies a specific person and manages the specific person by information. By having one inpatient or staff on the hospital side possess one IC card that enables management of multiple devices of different types and types, the inpatient or the staff on the hospital side can live in the hospital. The present invention relates to a card system management device that makes it possible to make medical treatment activities convenient and improved.

2. Description of the Related Art In recent years, systems for purchasing goods and services have become widespread, such as telephone cards, orange cards (trademarks), cards for vending machines at gas stations, rental businesses, restaurants, and the like. These cards are purchased by the user in advance and purchased, and are called prepaid cards.

FIG. 15 shows a block diagram of a card system management device in a conventional prepaid card system. Here, a prepaid card system for pay television will be described as an example. The CPU 6 operates according to the program written in the RAM 8. Prepaid card 2
When is inserted into the card reading / writing device 4, the CPU 6 reads the remaining number stored in the prepaid card 2 (reads into the internal register or RAM). Next, according to the output from the device operation detector 10, it is determined whether or not the television is operating. If the TV is working, CP
U6 subtracts a predetermined frequency from the read residual frequency according to the output of the time measuring means 12. At the same time, the current remaining frequency is displayed on the display unit 14. When the user finishes using the television and stops the operation, the CPU 6 writes the current remaining number from the card reading / writing means 4 to the prepaid card 2. Then, the prepaid card 2 is ejected in order to return the card 2 to the user. If the current remaining number becomes 0 during use of the TV, the CPU 6 turns off the power of the TV and forcibly stops the operation of the TV. As described above, with the prepaid card system, pay television can be viewed without preparing cash every time the user uses the card.

However, the above-described conventional prepaid card system management device has the following problems. That is, a dedicated card system management device is required for each device to be used. Therefore, many card system management devices are required, which not only makes the system expensive but also occupies a large installation space.
In addition, a dedicated prepaid card must be prepared for each device, which increases the number of cards for the user, making it difficult to manage and store the cards.

The inventor of the present invention provides a prepaid card system device capable of managing a plurality of devices by a single device, as disclosed in Japanese Patent Laid-Open No. 4-60789, and solves the above problems to some extent. We were able to do it, but we have not yet solved the following. For example, if the card user is an inpatient in a hospital 1
If you are a person who stays in a building for a short period of time, you have to carry a lot of cards related to treatment activities, ID cards that identify yourself and other cards. Poor usability in which the amount of money cannot be recorded on the card by inserting cash with the card inserted. Settlement by a register (terminal) installed in the shop. Liquidation at the time of admission and discharge. Individual confirmation when the patient himself / herself undergoes medical examination or examination. A doctor in charge or a laboratory technician searches for a patient number with a card reader of a terminal to obtain medical record data or examination data, or updates such data. (In the past, ID cards were separately provided to patients to do these things.) Loss of providing staff ID cards separately for staff attendance, location management, entry management, etc. Lost the provision of separate qualification cards such as terminal qualification confirmation and database access qualification ranking.

Power is supplied to the TV 34a, the video 34b, and the range 34c, which are the management devices corresponding to the usage time, through the card system management device 1. The power switch 40, 42, 44 is provided with a switch 4
6, 48 and 50 are provided and controllable from the output ports 0 ₁ , 0 ₂ and 0 _{3 of} the CPU 52. In addition, each power line 40, 42 and 44, the current detection transformer 54, 56, 58 is provided and its output is applied to input port ₁ 1, 1 _2, 1 ₃ of the CPU52 through the detection circuit 60 . The detection circuit 60 includes transformers 54 and 5
The outputs from 6, 58 are discriminated by a predetermined threshold,
The presence or absence of current in the power supply lines 40, 42, 44 is determined. That, CPU 52 can know by taking the output of the detection circuit 60 from the input port ₁ 1, 1 _2, 1 _3, each operating time corresponding devices 34a, 34b, whether 34c is in use. As described above,
In this embodiment, the transformers 54, 56, 58 and the detection circuit 60 form a device operation detecting means for use time.

[0016] On the other hand, from the vending machine 35a is sold number compatible device, via a control line 43, sales request signal is applied to an interrupt input port 1 ₄ CPU 52. Further, from the output port 0 ₄ CPU 52, the control line 4
A vending machine 35a is given a sales permission signal via the V.5. The power supply to the vending machine 35a is not controlled by the management device 1 but is performed independently.

The CPU 52 is provided with a RAM 64 and a timer 6 via a bus line (control bus and data bus) 62.
6, a display circuit 68, a read / write circuit 72, and a card carrying section 74 are connected. The RAM 64 stores programs such as frequency subtraction, information transmission, and deposit / payment. The RAM 64 is backed up and retains its contents even when the power is turned off. FIG.
The front operating portion of the card system management device 1 is shown in FIG.
The display unit 69 is composed of an LCD or the like, and includes the display circuit 6
According to the command of 8, the operation guidance, the current remaining frequency, the deposit amount and the balance are displayed. A card transport unit 74 is provided at the back of the card insertion port 73 to receive and eject the card. Also, by pressing the card eject button 75, the card is forcibly ejected.

(Operation Program Corresponding to Usage Time) FIGS. 4 and 5 are flowcharts of the frequency subtraction program stored in the RAM 64. FIG. 4 is for managing the television 34a, the video 34b, and the range 34c (equipment for use time), and FIG. 5 is for managing the vending machine (equipment for sale quantity) 35a. In addition,
Normally, the program of FIG. 4 is operating, but the program of FIG. 5 is operated by the interrupt operation.

First, the program of the equipment for use time shown in FIG. 4 will be described. When the IC card 80 is inserted from the card insertion slot, the card transport unit 74 operates and I
The C card 80 is taken inside. At the same time, the CPU
A read command is issued from 52, and the read / write circuit 72 operates to read the data in the card. The CPU 52 stores this data in the RAM 64.

Data is stored in the IC card 80 as shown in FIG. The card type code stores a code indicating that the card is an IC card. The system type card is a code stored to distinguish the card for another system from the card for another system. Finally, the remaining frequency, balance, information and prohibition clause are stored.

Next, in step S ₂₀ , the CPU 52 determines whether the system type code read into the RAM 64 matches the type code of the system. If the system type codes do not match, the CPU 52
Interrupts the frequency subtraction process. After that, the card transport unit 74
Control to eject the card. If the system type codes match, the process proceeds to step S _21, and displays the guidance of "Turn on" on the display unit 69. Accordingly, the user turns on the switch (not shown) of the desired television 34a, video 34b, range 34c. At this time, the switches 46, 48 and 50 are still open, and it is determined whether or not the remaining number of power supplies to the switch-on device is 0 (step S ₂₂ ). If the remaining frequency is 0, the process is interrupted. Then, the card transport unit 74 is controlled to carry out the card.
That is, the use of the card is not permitted. If the remaining power is positive, the process proceeds to step S _23, all the switches 46, 48,
Close 50. As a result, only the device that the user has turned on in step S ₂₄ starts operating.

Next, the CPU 52 fetches the output of the detection circuit 60 from the ports 1 ₁ , 1 ₂ , 1 ₃ and judges which of the usage time corresponding devices is in use (step S ₂₅ ). The case use time corresponding equipment in use there is no (i.e. if any to no current flows through the power supply lines 40, 42, 44), repeatedly executes steps S _23, S _24, put the "Power Please display the guidance. If there is equipment in use, the process proceeds to step S _26, turn off the guidance of "Turn on the power." Next, the display unit 69 the current equipment usage (step S _27).

Next, the total frequency subtraction coefficient M is calculated based on the frequency subtraction coefficient for each device, which is determined by the usage charge per unit time, and which device is being used (step S ₂₈ ). The power subtraction coefficient of the device (television) 34a is a, the power subtraction coefficient of the device (video) 34b is b, and the power subtraction coefficient c of the device (range) 34c is
Then, the total frequency subtraction coefficient M is obtained as shown in FIG. The total frequency subtraction coefficient M may be obtained by preparing a table as shown in FIG. 12 in the RAM 64, or may be calculated by the following arithmetic expression. M = A ₁ · H ₁ + A ₂ · H ₂ + A ₃ · H ₃ + ... + A
_n · H _n However, the variables representing the presence / absence of the operation of each usage time compatible device are A ₁ , A ₂ ... An, and the variables representing the frequency subtraction coefficient of each usage time compatible device are H ₁ , H ₂ · ··· Hn. The subscript of each variable represents the number of the equipment corresponding to the usage time, and the variables A ₁ , A ₂ ... An are 1 if the equipment corresponding to the usage time is operating, and 0 if they are not operating.
Is the content.

Next, the usable time (1
Cycle time Tm) is calculated based on the following equation (step S ₂₉ ). Tm = reference time T / subtraction coefficient M In this embodiment, the reference time is about 10 minutes. When 1 cycle time Tm is calculated, RAM
A predetermined frequency is subtracted from the residual frequency stored in 64 to update it as a new residual frequency (step S ₃₀ ). That is, in this embodiment, a prepaid system is adopted.

Next, in step S ₃₁ , it is determined whether the residual frequency is negative or positive. If the residual frequency is positive,
The CPU 52 writes the remaining count on the card by the read / write circuit 72 (step S ₃₂ ). And timer 6
1 cycle time Tm is set to 6 (step S ₃₃ ). Then, CPU 52 in accordance with clocking until one cycle time is completed (until the timer 66 counts up) the timer 66 is subtracted changing the frequency display (step S _{34, 35).} When one cycle time is completed, the flow returns to step S _25. At that time, if there is a use state of the device (increase / decrease of the device for use time in use), one cycle time is calculated by the subtraction coefficient M corresponding thereto. That is, appropriate card management can be performed even when a plurality of devices are used at the same time.

[0026] (Step S _31), if the calculated remaining power is negative calculates the remaining time Tx (step S _36). Then, the read / write circuit 72 writes the residual number 0 to the card (step S ₃₇ ).
Then, the remaining time Tx is set in the timer 66 (step _S38 ). After that, the CPU 52 subtracts and changes the frequency display according to the time count of the timer 66 until the remaining time Tx elapses (until the timer 66 counts up) (steps S ₃₉ and S ₄₀ ). When the remaining time Tx has elapsed, all the switches 46, 48, 50 are opened, and the devices 34a, 34b,
The power supply to 34c is forcibly stopped (step _S41 ).
After that, the processing is terminated and the IC card 80 is ejected.

By the way, when the IC card 80 has a residual number remaining, when the use of the devices 34a, 34b, 34c is stopped, the card take-out button 75 is pushed. When the button 75 is pressed, the signal is applied to the interrupt port 1 ₀ CPU 52, CPU 52 performs the interrupt operation. In the interrupt operation, CPU 52, first stops the subtraction timer 66 (step S _50). Further, the remaining frequency at that time is written on the card (step S ₅₁ ). Thereafter, the processing is terminated, and the card is ejected.

(Operation program corresponding to sales quantity) Next,
FIG. 5 shows an operation when a product is purchased from the vending machine 35a.
This will be described with reference to FIG. When a product selection / purchase button (not shown) of the vending machine 35a is pressed, the vending machine 35a outputs a sales request signal. This signal, via line 43, supplied to the interrupt input port 1 ₄ CPU 52,
Receiving this, the CPU 52 executes the program of FIG. 5 by interrupt processing. Therefore, the CPU 52
The execution of the program of FIG. 4 is temporarily suspended, and the program for the vending machine 35a is executed. The interrupt processing is performed in order to handle the sales request from the vending machine 35a at any time. In addition,
The processing of FIG. 5 may be performed by multitasking instead of interrupt processing.

FIG. 13 shows a sales request signal sent from the vending machine 35 to the CPU 52. It is composed of a control code added for transmission and a product code that is a sales request target. When there is an interruption due to the sales request signal, the CPU 52 obtains the frequency subtraction coefficient corresponding to the sent product code (step S ₈₀ ). A table as shown in FIG. 14 is prepared in the RAM 64, and C
The PU 52 obtains the corresponding frequency subtraction coefficient according to this table. The frequency subtraction coefficient is a value obtained by converting the amount of money per one product (or one pack or the like) as a frequency. In this embodiment, the interrupt process is performed every time there is a sales request for one product.
52 proceeds to the next step with this frequency subtraction coefficient as the product sales frequency subtraction coefficient N. In addition, for vending machines that can perform bulk buying, the product sales frequency subtraction coefficient N is calculated by adding up the frequency subtraction coefficients of the products purchased collectively.

Next, the CPU 52 subtracts the above-mentioned merchandise sales frequency subtraction coefficient N from the residual frequency stored in the RAM 64 to calculate a new residual frequency (step S ₈₁ ). Next, it is determined whether the residual frequency is negative or positive. If the residual frequency is positive, the CPU 52 causes the read / write circuit 72 to
The new remaining frequency is written to the card by (step _S83 ). Then, from the output port 0 _4, and outputs a vending command signal (step S _84). This signal is given to the vending machine 35a via the line 45. Vending machine 35
Upon receiving this sales command signal, a releases the product. At the same time, the CPU 52 turns on the display "Sold product" on the front surface of the main body for a predetermined time (step _S85 ). After that, the interrupt processing is terminated, and the process returns to the program of FIG. In step _S82 , if the residual number is negative, the interrupt processing is terminated without issuing the sales command signal, and the process returns to the program of FIG. When the prohibition clause of the card and the prohibition clause of the system match, the card is ejected (FIG. 6, step S ₁₁ ).

By the way, in this embodiment, the RAM
The operation program and charge setting data stored in 64 are also rewritten by the card. That is, in addition to the frequency subtraction processing described above, the operation program setting processing,
It has a mode of charge setting processing. The supervisor card 82 of FIG. 10 is used for the operation setting process, and the fee setting card 84 of FIG. 11 is used for the fee setting process. The supervisor card 82 stores a card type code, a master code, an operation program, constants for various operations, and a system type code. The charge setting card 84 stores a card type code, a system type code, a charge calculation program, and a charge calculation constant.

FIG. 6 shows an overall flow chart including the frequency subtraction mode, the operation program setting mode, and the fee setting mode. The frequency subtraction process shown in FIGS. 4 and 5 is represented as step S _{10 in} FIG.

First, in step S ₁ , when the card system management device 1 is powered on, the CPU 52 is reset to the initial state. Next, the CPU 52 opens all the switches 46, 48, 50 to bring them into a cutoff state (step S ₂ ). That is, power is not supplied to the television 34a, the video 34b, and the range 34c unless a card is inserted. In this state, CPU5
2, controls the display circuit 68, the display of "Please put your card" on the display unit (step S _3). Next, when a card is inserted through the card insertion slot 73, the "Please insert card" display disappears. (Step S _6). Next, the data stored in the card is read into the buffer in the RAM 64 via the read / write circuit 72 (step S ₄ ).

Next, in step S ₇ , the CPU 52
Determines the card type from the card type code of the inserted card. Assuming that IC card 80 is inserted, CPU 52 performs a frequency subtraction processing in FIG. 4 (step S _10).

(Operation Program Setting Device) If the card is the supervisor card 82, an operation program setting process is performed. FIG. 7 shows a flowchart of the operation program setting process. First, in (step S ₆₀ ), the suitability of the master code stored in the supervisor card 82 is checked. This master code proves that the supervisor card 82 is a correct card. If the master code is not correct, then ends the operation program setting process, and discharges the card (FIG. 6, step S _11).

When the master code is correct, C
The PU 52 stores the operation program stored in the card in the R
Transferred to the operation program area of AM64 (step S _61). When the operation program is already stored in the RAM 52, the previous operation program is erased by overwriting the new operation program. In addition to the operation program, the operation constants that determine the operation of the card system management device 1 are also transferred to the RAM 64. here,
The operation constant is a constant that determines the basic operation of the management device 1, and is, for example, a numerical value that determines the timing of lighting the operation guidance and the timing of card ejection.

Next, stores system type code in RAM 64 (step S _62). The system type code is a code for determining what kind of system the management device is used for. For example, for a card system that targets only a specific area / equipment, the specific system type code is stored in the RAM 64 of the management device, and the matching with the system type code of the IC card 80 is determined ( (See FIG. 4, step S ₂₀ above). Therefore, there is no risk of the management device being activated by cards of different systems.

[0038] As described above, if stored RAM64 operation programs and operation constant, and the process ends, and discharges the card (FIG. 6, step S _11). After that, the management device operates according to the newly stored operation program. That is, the programs shown in FIGS. 4 and 5 (or one of them) are changed to new contents. In this way, just by inserting the supervisor card 82,
The operation program can be set and changed. Therefore, it is possible to extremely easily change the operation of the management device 1 or use the management device 1 for another system.

(Charge Setting Processing) In this embodiment,
The charge setting / change is separately performed by the charge setting card 74. This takes into account that the charge change is performed more complicatedly than the system change, and that the subject of the charge change is often different from the subject of the system change. In step S ₇ of FIG.
If it is determined by the card type code that the card is a charge setting card, a usage charge setting process is performed (step S
₉ ). A flow chart of the charge setting process is shown in FIG. First, in step S _70, the appropriateness of the stored system type card is judged on the card. If the system type code stored in the card is different from the system type code stored in the RAM 64, the process is terminated and the card is ejected because it is a fee setting card for another system (FIG. 6 step). S ₁₁ ).

If the system type code matches the one stored in the RAM 64, the charge calculation program and the charge calculation constants (the subtraction frequency of all kinds of Tsuba etc.) stored in the card 84 are written in the RAM 64 (step S). ₇₁ ). If writing is completed, the card is discharged (Fig. 6, step S _11). After that, the calculation is performed by a new charge calculation program (for example, the frequency subtraction coefficient M of each device or the frequency subtraction coefficient N of each product is changed). That is, the charge calculation portion of the programs of FIGS. 4 and 5 is changed. In this way, the charge calculation can be easily changed only by inserting the charge setting card 84.

(Other Embodiments) In the above embodiment, the use time corresponding devices connected to the card system management device are three, but one, two, four or more may be used.
