SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a communication control system capable of improving efficiency.

That is, the communication control system of the present invention is provided with a schedule file device and an execution control device for a communication network, and the schedule file device has at least (a) a status flag area (b) a time information area. (c) Consists of a set of schedules having a communication control information area,
The execution control device reads out from the schedule file device a schedule to be executed according to the information in the (a) status flag area, and (b) information in the time information area and the current time in the read schedule. And a communication control means for sending (c) communication control information to a communication network when executing communication.

Although the schedule file device may be configured as a single device, it is configured by a master schedule file and an execution schedule file.
It is desirable to transfer the necessary schedules for each day, week, month, etc. from the master schedule file to the execution schedule file.

The time information area in each schedule is
It is composed of information on start time, delay start time, delay interval time, and delay allowable time. The start time is a time at which the schedule should be executed, and the delayed start time is a time at which the schedule should be re-executed when the schedule cannot be executed due to some failure. The delay interval time defines a time interval until re-execution when the schedule cannot be executed. The delay allowable time is the time from the start time when the schedule can be re-executed.

Here, the delay interval time and the delay allowable time may be set not as information for each individual schedule but as information common to all schedules on the side of the execution control device, for example, the time monitoring means. .

[0011]

According to the communication control system of the present invention, it is possible to control communication according to the information in the information flag area and the time information area of each schedule accumulated in the schedule file device. As a result, it becomes possible to control a plurality of schedules at the same time.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the system of the embodiment, which is composed of a schedule file device 1 and an execution control device 2. The schedule file device 1 is composed of a master schedule file 3 and an execution schedule file 4. The execution control device 2 includes an execution schedule generation device 5 and a reading device 8 having a time monitoring device 6 and a communication control device 7.

The master schedule file 3 constituting the schedule file device 1 stores the master schedules 9 and 9 shown in FIG. Each master schedule 9 has a communication control information area 10
A time information area 11 such as a day, a week or a month to communicate with, a time to communicate, a delay interval time, etc. is formed, and predetermined information is recorded for each schedule.

The execution schedule file 4 is transferred from the master schedule file 3 via the execution schedule generation device 5 and the necessary master schedule 9 (extracting a schedule to be executed in units of days, weeks or months) is transferred and stored. Is a file that is The configuration of the execution schedule 9a stored in the execution schedule file 4 is as shown in FIG.
2, a status flag area 13, a start time area 14, a delay start time area 15, a delay interval time area 16, and a delay allowable time area 17 are formed. In each area, the communication control information of the master schedule 9 is formed. Information according to the information recorded in the area 10 and the time information area 11 is recorded. The status flag area 13 is an area in which information on communication waiting or communication completion is recorded, and the execution schedule 9a
Is initially recorded as waiting for communication.

In the figure, reference numeral 18 is a communication network, 19 is a modem, 20 is a computer constituting a terminal of the communication network 18, and 21 is a transmission / reception data file.

The manner of execution of the above embodiment will be described below.
It is assumed that the required execution schedule 9a is stored in the execution schedule file 4.

The reading device 8 has an execution schedule 9a,
The status flag area 13 of 9a reads the execution schedule 9a waiting for communication.

Execution schedule 9 waiting for communication
When there are a plurality of a, the execution schedule 9a having the highest priority is determined (priority determination processing). The determination of the priority is performed based on a predetermined determination criterion, for example, the pre-rear relation of the time recorded in the start time area 14 or the magnitude of the communication urgency. When the priorities are the same, the determination is made based on another criterion such as the earliest start time. In this way, when the execution schedule 9a waiting for communication is read, the time information (for example, 9:00 am) in the start time area 14 of the read execution schedule 9a and the current time received from the clock unit 22 of the computer 20 are read. A time monitoring process for comparing
As a result of the comparison, when the current time is the same as or later than the time set in the start time area 14, the communication control device 7 is activated, and the information in the communication control information area 12 in the execution schedule 9a is stored in the computer 20. Sent to.

In the communication control information area 12, information including a telephone number of a communication partner, a password, etc. is recorded. Based on these information, the data stored in the transmission / reception data file 21 is stored. Among them, necessary data is transmitted to a predetermined destination via the communication network 18 via the computer 20, or conversely, required data is received from the communication destination and stored in the transmission / reception data file 21.

When the execution of the predetermined communication is completed in this way, a communication completion signal is sent from the computer 20 to the execution control device 2 side, so that the reading device 8 communicates the information in the status flag area 13 of the execution schedule 9a. It is rewritten as complete and returned to the execution schedule file 4.

On the other hand, when communication cannot be executed due to some trouble, a communication failure signal is sent to the computer 20.
From the execution control device 2 side. The reading device 8 keeps the information in the status flag area 13 of the execution schedule 9a as it is (that is, waiting for communication), and adds the time (for example, 5 minutes) recorded in the delay interval time area 16 to the current time to the delay start time area 15. Then, the time to be executed next is calculated, the time is recorded, and the result is returned to the execution schedule file 4.

As described above, the plurality of execution schedules 9a stored in the execution schedule file 4 can be sequentially executed. In the read execution schedule 9a, when the time is recorded in the delay start time area 15, the information recorded in the start time area 14 is ignored, and the time recorded in the delay start time area 15 and the current time are recorded. Compare the times. In addition, the time recorded in the delay start time area 15 becomes the time recorded in the start time area 14,
The time recorded in the delay allowable time area 17 (for example, 60
If the time calculated by adding (minutes) has elapsed, communication is not executed even if the status flag area 13 is waiting for communication. The above flow is shown in the flow chart of FIG.

In the embodiment, the schedule file device 1 is described as being composed of the master schedule file 3 and the execution schedule file 4, but it is possible to use only the master schedule file 3 in a simple system.

The delay interval time region 16 and the delay permissible time region 17 in the execution schedule 9a may be omitted for each execution schedule 9a. For example, it is possible to perform the same communication control as described above by setting the delay interval time information and the delay allowable time information as the information common to all schedules in the time monitoring device 6.

[0026]

As described above, according to the present invention, since a plurality of communication schedules can be controlled simultaneously, the control efficiency can be improved.

When the communication execution fails, the time interval for re-execution can be freely set for each individual schedule or common to all schedules, and the communication execution fails. It is also possible to control the infinite re-execution at the end.

Further, even if there are schedules having the same communication start time or delayed start time, the communication can be surely executed within a predetermined allowable time, so that the execution is not performed unintentionally. It is possible to prevent accidents.
