FIG. 3 is a configuration diagram showing an enlarged portion. In the figure, a main control unit 2 reads data relating to each sub-function, display / interlocking data, etc. from an IC card 1 and sends it to a corresponding sub-processor (MPU).
A ROM (Read Only Memory) 22 in which programs related to a flowchart shown in FIG. 3 described later are stored in advance, information temporarily read from the IC card 1 by the MPU 21, and the like. And a RAM (random access memory) 23 used as a working memory for temporarily writing and reading data during arithmetic processing.

The sub-control unit 4 is provided with the M
The liquid crystal display (LCD) 11 and the light emitting element (LE) are connected to the PU 21 based on the control information from the MPU 21.
D) MPU 41 for controlling the display and fetching of the state of the operation switch (SW) 13 and the operation switch (SW) 13, respectively.

Similarly, reference numerals 32 and 33 denote a pair of three-state buffers provided between the MPU 41 and the IC card 1, respectively, wherein the buffer 32 is for addresses and the buffer 33 is for data. These buffers 32 and 33 store the MPU 4 generated in response to a control command from the MPU 21 to enable or disable access to the IC card.
The control signal from 1 controls the conduction and non-conduction. Note that the buffers 30 to 33 constitute switching means.

The main control device 2 and the sub control device 4
When reading information from the C card 1, the buffers 30 and 31 on the MPU 21 side and the buffers 32 and 33 on the MPU 41 side operate in reverse to each other. That is, when the main controller 2 reads information from the IC card 1, the MPU 21
1 is turned on, the IC card 1 is accessed via the buffer 30, and information from the IC card 1 is read via the buffer 31. Also, the MPU 21 has a buffer 32 in advance.
And MPU of the sub-control unit 4 so that
A control command to the IC card 41 to disable IC card access is generated. Therefore, at this time, upon receiving a control command from the MPU 21 to disable IC card access, the MPU 41 turns off the buffers 32 and 33.

On the other hand, when the sub-controller 4 reads information from the IC card 1, the main control unit 2 causes the MPU 21 to make the buffers 30 and 31 non-conductive and at the same time to make the buffers 32 and 33 conductive. MP
A control command to enable access to the IC card is issued to U41. Accordingly, at this time, the MPU 41, which has received the control command for permitting the access to the IC card from the MPU 21, sends the signal indicating that the IC card is being accessed or the IC card is prohibited to the MPU 21, and simultaneously the buffers 32 and
3 is turned on, the IC card 1 is accessed via the buffer 32, and information from the IC card 1 is read via the buffer 33.

Next, the operation will be described with reference to FIGS. In the figure, the main indicates the main control device 2 and the sub 1 indicates the sub control device 4. First, the operation of main controller 2 will be described with reference to FIG. First, initial processing such as initialization is performed (step S1), and then the MPU 21 of the main control device 2
The control command for inaccessible C card is sent to the MP
It is sent to U41 (step S2). MPU21
Makes the buffers 30 and 31 conductive, accesses the IC card 1 via the buffer 30, and transmits information from the IC card 1 via the buffer 31, for example, data related to the function of each sub-control device and display / interlocking data. Read, RA
Store it in M23.

After reading the information from the IC card 1 is completed, the main control unit 2 next issues a control command for enabling access to the IC card from the MPU 21 to the M of the sub control unit 4.
It is sent to the PU 41 (step S4). Then
The sub-controller 4 starts reading information from the IC card 1 described later with reference to FIG.
From IC card access to MPU 21
A C card access prohibition signal is sent. Therefore, in step S5, the MPU 21 of the main control device 2 determines whether the access in the sub-control device 4 has been completed, that is, whether the IC card is being accessed or the input of the IC card access prohibition signal has been stopped. If not, the process waits until the process is completed. When the process is completed, a control command to prohibit access to the IC card is sent to the MPU 41 of the sub control device 4 (step S6), and then the monitoring state is entered.

Now, in the monitoring state, step S7
In, it is determined whether there is a signal indicating a change in the state of the terminal device. As a change in the state of the terminal device, for example, although not shown, the generation of an operation signal such as a fire alarm of a fire detector and the operation of a transmitter can be considered. In step S7, the process waits until there is a change in the state of the terminal device.
Then, the display / linkage data read from the IC card 1 stored in the sub-controller 4 is read out (step S8), and the address of the terminal device whose status has changed is sent to the MPU 41 of the sub-control device 4 (step S9). Next, data related to the printer 10 is transmitted (step S10), and a link command is transmitted to other terminal devices that are linked by the terminal device whose state has changed, and then linked by, for example, an on / off type smoke detector that has fired. Command (start command) for the smoke and smoke prevention equipment 17 to be activated
Is transmitted (step S11), the process returns to step S7, and the normal monitoring state is continued. Note that the procedure of step S8 and step S9 may be reversed.

Next, the operation of the sub control unit 4 will be described with reference to FIG. First, initial processing such as initialization is performed (step S21).
U41 determines whether there is an IC card access control command from the MPU 21 of the main control device 2 (step S41).
22) If not, wait until there is, if there is, main controller 2
A signal indicating that the IC card is being accessed is sent to the MPU 21 (step S23). Next, the MPU 41 makes the buffers 32 and 33 conductive, accesses the IC card 1 through the buffer 32, and accesses the IC card 1 through the buffer 33.
Information such as display / interlock data from the card 1 is read and stored in the RAM 43 (step S24).

Thus, the sub-controller 4 has finished reading the information from the IC card 1, and then the MPU 41 sends the IC which has been transmitted to the MPU 21 of the main controller 2.
Cancel the instruction during card access (step S2
5). Then, a normal monitoring state is entered.

Now, in the monitoring state, step S2
In step 6, it is determined whether or not there is a call from the main control device 2 by polling. If there is a call, a signal from the main control device 2 is read and stored in the RAM 43 (step S27). If there is no call in step S26, or if the operation in step S27 is completed, the process proceeds to step S28, where it is determined whether or not there is an interrupt signal by the operation switch (SW) 13. If there is an interrupt signal, the interrupt signal is sent. The signal is sent to the main controller 2 (step S29), and if there is no interrupt signal, a signal indicating no state change is sent to the main controller 2 (step S3).
0).

When the operations in steps S29 and S30 are completed, the process proceeds to step S31, where it is determined whether or not a signal from main controller 2 has a control command.
If there is a control command, control of the light emitting element (LED), for example, light emission (step S32), then proceed to the next step S33, and if there is no control command in step S31, proceed to step S33. In step S33,
It is determined whether or not the signal from the main controller 2 includes a display command. If there is a display command, the corresponding display data is read from the RAM 43 (step S34), and the liquid crystal display device (L
After displaying on the CD) 11 (step S35), the process returns to step S26 to continue the normal monitoring state. If there is no display command in step S33, the process returns to step S26 to continue the monitoring state.

As described above, in the present embodiment, for example,
The information read from the C card 1 is printed by the printer 10 connected to the main controller 2 and the sub controller 4
When the information is to be displayed on the liquid crystal display device 11 connected to the IC card 1, the information can be read from the IC card 1 from the main control device 2 and the sub-control device 4 almost simultaneously, and the printing and display can be performed substantially simultaneously. So, like the conventional device,
The information read from the IC card by the main control device does not need to be once selected, aligned, and sent to the sub control device, so that the processing time can be shortened accordingly.

FIGS. 5 and 6 are flow charts showing another embodiment of the present invention. Note that the circuit configuration in this embodiment may use the same circuit configuration in FIG. 2 as in the above embodiment. Therefore, the illustration is omitted here. Next, the operation will be described with reference to FIGS. In the drawings, the main indicates the main control device 2 and the sub 1 indicates the sub control device 4 as in FIGS. 3 and 4. First, the operation of main controller 2 will be described with reference to FIG. First, initial processing such as initialization is performed (step S41), and then the MPU 21 of the main control device 2 sends a control command to disable IC card access to the MPU 41 of the sub control device 4 (step S42). The MPU 21 makes the buffers 30 and 31 conductive, accesses the IC card 1 via the buffer 30, reads information from the IC card 1 via the buffer 31, for example, data related to the function of each sub-control device, and stores it in the RAM 23. I do.

Next, in the monitoring state, step S4
At 4, it is determined whether there is a signal indicating a change in the state of the terminal device. In step S44, the process waits until there is a change in the state of the terminal device. If there is a change, the display / linkage data is read from the IC card 1 (step S45).
The address of the terminal device whose status has changed is stored in the MP of the sub-control device 4.
UPU 41 (step S46) and MPU 2
1 to the sub-controller 4
(Step S46A).

Next, in step S47, the MPU 21 of the main control device 2 determines whether or not the access in the sub-control device 4 has been completed, that is, whether or not the IC card is being accessed or the input of the IC card access prohibition signal has been eliminated. If the access is not completed, the process waits until the access is completed, and when completed, sends a control command to the MPU 41 of the sub-control device 4 to disable the IC card access (step S48). Next, data related to the printer 10 is transmitted (step S49), and a linking command is transmitted to other terminal devices linked by the terminal device whose status has changed, and then linked by, for example, an on / off type smoke detector that has issued a fire. After transmitting the interlocking command (start command) to the smoke prevention equipment 17 (step S50), the process returns to step S44.
Continue monitoring. Note that, in this case as well, step S4
5 and step S46 may be reversed.

Next, the operation of the sub control unit 4 will be described with reference to FIG. First, initial processing such as initialization is performed (step S51).
2, the MPU 41 of the sub control device 4
It is determined whether or not there is a call by polling, and if there is a call, a signal from main controller 2 is read and stored in RAM 43 (step S53). If there is no call in step S52, or step S53
Is completed, the process proceeds to step S54, where it is determined whether or not there is an interrupt signal from the operation switch (SW) 13. If there is an interrupt signal, the interrupt signal is sent to the main controller 2 (step S55). If there is no interrupt signal, a signal indicating no state change is sent to main controller 2 (step S56).

When the operations in steps S55 and S56 are completed, the process proceeds to step S57, where it is determined whether or not a signal from main controller 2 has a control command.
If there is a control command, the light emitting element (LED) is controlled (step S58), and then the process proceeds to the next step S59.
Go to 59. In step S59, it is determined whether or not a signal from the main control device 2 includes a display command. If there is a display command, the MPU 41 of the sub control device 4
It is determined whether or not there is a control command to permit IC card access from U21 (step S60). If there is no command, the process waits until there is, and if so, sends a signal indicating that the IC card is being accessed to MPU 21 of main controller 2 (step S60). S61).
Next, the MPU 41 makes the buffers 32 and 33 conductive, accesses the IC card 1 via the buffer 32,
Information from the IC card 1, for example, display / linkage data is read from the buffer 33 (step S62).

Since the reading of the information from the IC card 1 has been completed, the sub control unit 4
The command sent to the MPU 21 of the IC card being accessed is withdrawn (step S63). Next, after the display data read in step S62 is displayed on the liquid crystal display (LCD) 11 (step S64), the process returns to step S52 to continue the normal monitoring state. Also, if there is no display command in step S59, step S59 is executed.
Returning to 52, the monitoring state is continued.

As described above, in the present embodiment, the display / interlock data of the corresponding terminal device is read from the IC card only when the state of the terminal device has changed. It is not necessary to write data in the RAM in advance, so that the memory capacity of the RAM can be reduced and the processing time until the monitoring time can be shortened.

In each of the above embodiments, the case of the main control device 2 and the sub-control device 4 has been described. However, the present invention is not limited to this, and the main control device 2 and the sub-control device 5 having other functions can be used. 9 can be applied in the same way, and the same effect can be obtained.
