Description

Description: TECHNICAL FIELD The present invention relates to a communication terminal device and a communication terminal system having a storage device for storing a communication message.

(Prior Art) Conventionally, in this type of communication terminal system, a communication message (sent / received document) is recorded by the following methods (1) and (2).

(1) A communication message is stored (recorded) for each communication in a storage unit (a memory circuit including a random access memory or the like) inside the apparatus.

(2) A communication message is stored (recorded) in a storage device (magnetic disk device or the like) outside the device for each communication.

(Problems to be Solved by the Invention) However, the above-described conventional method of recording a communication message by the communication terminal system has the following problems.

According to the method (1), the number of communication messages to be stored (recorded) is limited because the memory capacity of the internal storage unit is limited. Alternatively, there has been a problem that the operator has to transfer the recorded communication message to an external storage device, which requires a complicated operation.

In the method (2) described above, since the external storage device operates for each communication, there is a problem that the life of the external storage device is shortened due to an increase in the number of operations.

Accordingly, an object of the present invention is not to limit the number of communication message records in view of the above-described conventional problems, to improve the life of the external storage device as compared with the conventional one, and to make the operator complicated as in the conventional case. An object of the present invention is to provide a highly reliable communication terminal system that does not require a message transfer operation.

(Means for Solving the Problems) The present invention relates to a communication terminal device having a storage unit for storing a communication message therein, and an external storage device for storing a communication message transferred from the storage unit of the communication terminal device. And a timekeeping unit for measuring time, when a preset time is reached, if a communication message is stored in the storage unit, the communication message together with time information is stored in the external storage means. When the communication message stored in the storage unit is deleted after the transfer is completed, and the communication message in the storage unit is not stored, a message indicating that there is no communication message together with the time information is stored in the external storage unit. It is provided with a control unit for storing.

(Operation) Therefore, the communication terminal system of the present invention transfers the communication message together with the time information to the external storage unit when the communication message is stored in the storage unit when the predetermined time specified in advance is reached. At the same time, after the transfer is completed, by deleting the communication message stored in the storage unit, the communication message can be repeatedly stored in the storage unit, so that the number of communication messages stored (stored) as in the related art can be reduced. There are no restrictions.

Further, at a predetermined time, the communication message stored in the storage unit is transferred to the external storage device, so that the number of operations of the external storage device is reduced as compared with the conventional case, the life is improved compared to the conventional case, and the operation is performed without an operator. Since the data can be transferred from the storage unit, complicated communication message transfer work of the operator is reduced.

Furthermore, even when there is no communication message, when a predetermined time is reached, a message indicating that there is no communication message is stored in the external storage device together with the time information, so that the external storage device is periodically updated after the predetermined time. By confirming, it can be confirmed that there is no communication message.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of a communication terminal system according to the present invention.

In FIG. 1, reference numeral 1 denotes an information input device including a keyboard, and the information input device 1 is connected to a control unit 2. The control unit 2 is a circuit for arithmetic processing including a microprocessor, a program memory, a predetermined input / output (I / O) interface, and the like. The control unit 2 has a clock control unit 3 including a clock IC and the like.

Reference numeral 4 denotes a line control unit connected between the control unit 2 and the communication line 5. The line control unit 4 controls a communication signal between the control unit 2 and the communication line 5. Communication control circuit.

Reference numeral 6 denotes a storage unit built in the communication terminal device connected to the control unit 2, and the storage unit 6 includes a memory circuit such as a random access memory (RAM). Reference numeral 7 denotes an external storage device connected to the control unit 2, and the external storage device 7 comprises a magnetic disk device or the like (here, a magnetic disk device is used).

Reference numeral 8 denotes a display device connected to the control unit 2, and the display device 8 includes a CRT display, a liquid crystal display, or the like. The display device 8 is a device that visually displays a document created by the operator using the information input device 1 and a communication message transmitted or received through the communication line 5.

Reference numeral 9 denotes a printing device connected to the control unit 2. The printing device 9 is a device that includes a dot printer or a thermal printer, and prints out a document or a message displayed on the display device 8. .

Under such a configuration, the operator operates the information input device 1 to control the control unit 2, and under the control of the control unit 2, performs communication via the line control unit 4. The communication message is first stored in the storage unit. 6 is transferred (recorded) to the external storage device 7 under predetermined conditions and stored.

In this case, when communication is performed, the line control unit 4 identifies whether the communication is transmission or reception, and notifies the control unit 2. The control unit 2 writes the message number and the transmission / reception identification code sequentially from the top address of the message storage area of the storage unit 6, and subsequently stores (records) the communication message. The recording of this communication message will be described with reference to FIG. FIG. 2 is an explanatory diagram of the contents of a message recorded in the storage unit 6.

For example, when transmission is performed as the first communication, first, the message number “001” is transmitted next, “S” indicating transmission, and finally the communication message is stored in the communication message storage unit 6. Addresses are stored (recorded) in order from the head address of an address (an address range in which a communication message can be stored) as illustrated. Next, when receiving as the second communication,
The message number “002”, the next “R” indicating reception, and the communication message are stored (recorded). Thereafter, the control unit 2 sequentially records the communication at the communication message storage address in the storage unit 6 in the same procedure for each communication.

Next, a case where a communication message stored (recorded) in the storage unit 6 is transferred to the external storage device 7 and stored (recorded) will be described with reference to FIG. FIG. 3 shows the first
6 is an operation flowchart of the control unit 2 in the figure.

First, the operator uses the information input device 1 to control the control unit 2.
In response to this, a time at which the communication message stored in the storage unit 6 is transferred to the external storage device 7 is designated in advance (step S1). The control unit 2 performs communication via the line control unit 4 and the communication line 5, and the control unit 2 sequentially stores the communication messages in a predetermined communication message storage address in the storage unit 6 as shown in FIG. It is stored (steps S2, S3).

The control unit 2 checks whether or not the storage amount (recording amount) of the communication message in the storage unit 6 is a certain amount (including approaching a certain amount as a communication message storage area) (referred to as near end) ( Step S4) If the recording amount of the communication message is a fixed amount, the process proceeds to step S6. If the recording amount of the communication message is not a fixed amount, the information is transmitted from the clock control unit 3 at a time designated in advance by the operator. It is checked whether there is (step S5). In step S5, if it is not the designated time, the process proceeds to step S2, and the flow of steps S2 to S4 described above is repeated. If the time is specified in advance, the process proceeds to step S6.

In step S6, the control unit 2 checks whether or not a transfer message (communication message to be transferred) can be written to the magnetic disk device of the external storage device 7, and if writing is not possible, an alarm (alarm sound or alarm signal, etc.) Occurs (step
S8) If writable, first the external storage device 7
The date / time is written to the magnetic disk device according to the information from the clock control unit 3 (step S7).

Next, the control unit 2 accesses the communication message storage address of the storage unit 6 and checks whether or not there is a transmission message by the transmission / reception identification code (“S”) added to the head address of the communication message. (Step S9) If there is no transmission message, the process proceeds to Step S12. If there is a transmission message, only the transmission message is read from the storage unit 6 and written into the magnetic disk device of the external storage device 7 (Steps S9 to S11). When there is no transmission message in step SS9, the control unit 2 writes a message "no transmission message" in the magnetic disk device of the external storage device 7 (step S17).

Next, in step S12, the control unit 2 checks whether or not there is a received message at the communication message storage address of the storage unit 6 by using the transmission / reception identification code (“R”) added to the head address of the communication message. If there is a received message, the received message is read from the storage unit 6 and written into the magnetic disk device of the external storage device 7 (steps S12 to S14).

Next, the control unit 2 deletes the communication message stored at the communication message storage address in the storage unit 6 (step S15). When there is no received message in step S12, the control unit 2 writes a message "no received message" in the magnetic disk device of the external storage device 7 (step S16).

As can be understood from the above description, the communication message in the storage unit 6 is transferred from the storage unit 6 to the magnetic disk device in the external storage device 7 by the control unit 2, and the communication message in the storage unit 6 is deleted. Since communication messages can be repeatedly stored in the storage unit 6, there is no limit on the number of communication messages to be recorded as in the related art.

In addition, under a predetermined condition, the control unit 2 here, when the recording amount of the communication message recorded in the storage unit 6 reaches a certain amount (step S4 in FIG. 3), or Even if the recording amount of the communication message recorded in the storage device does not reach the fixed amount, at a predetermined time (step S in FIG. 3).
5) Since the communication message stored in the storage unit 6 is divided into a transmission message and a reception message, and is automatically transferred from the storage unit 6 to the magnetic disk device of the external storage device 7 without the intervention of an operator and stored, The operator does not need to perform a complicated communication message transfer operation from the storage unit 6 to the external storage device 7 as in the related art, and the work load on the operator is reduced accordingly.

Also, the control unit 2 does not execute the communication recorded in the storage unit 6 every time a predetermined condition is satisfied, that is, when the recording amount of the communication message recorded in the storage unit 6 reaches a certain amount or not every communication. Even if the recorded amount of the message does not reach a certain amount, the communication message stored in the storage unit 6 is divided into a transmission message and a reception message at a predetermined time, and each is separately collectively stored in the external storage. Since the transfer to the magnetic disk device of the device 7 is performed, the number of times of operation of the magnetic disk device of the external storage device 7 is reduced as compared with the related art, and the life of the magnetic disk device of the external storage device 7 can be improved more than before.

Further, the control unit 2 adds a transmission / reception identification code to the communication message and stores the message in the storage unit 6, and further stores the communication message stored in the storage unit 6 in the magnetic disk device of the external storage device 7. Since the communication message is identified as the transmission message and the reception message by the transmission / reception identification code and stored separately in the magnetic disk device of the external storage device 7 as the transmission message and the reception message, The workability at the time of searching for stored (recorded) telegrams in the magnetic disk device of the storage device 7 can be improved as compared with the related art.

Thus, a highly reliable communication terminal system can be provided.

In this embodiment, as shown in FIG. 3, when a communication message is transferred from the storage unit 6 to the external storage device 7, a transmission message is transferred first, and then a reception message is transferred. S9 to S11, S12 to S16), the present invention is not limited to this, the transfer order of the transmission message and the reception message is reversed, the reception message is transferred first, and then the transmission message is transferred. May be configured.

Further, in this embodiment, before the communication message (transmission message) is transferred from the storage unit 6 to the magnetic disk device of the external storage device 7, the control unit 2 sends the clock control unit 3 to the magnetic disk device of the external storage device 7. Although the date / time designated by the user is recorded (the date and / or time may be recorded if necessary) (step S7 in FIG. 3),
The present invention is not limited to this. After the communication message is transferred from the storage unit 6 to the magnetic disk device of the external storage device 7 (for example, before the end of the flow in the flow of FIG. 3), the date / Time may be recorded after the communication message transferred and stored in the magnetic disk device of the external storage device 7.

The present invention is not limited to the present embodiment, and various applications and modifications can be considered without departing from the gist of the present invention.

(Effects of the Invention) As described above, the present invention has the following various effects.

(1) Under a predetermined condition, the communication message in the storage unit is transferred from the storage unit to the external storage device by the control unit, and the communication message in the storage unit is deleted. Therefore, the communication message is repeatedly stored in the storage unit. Therefore, there is no longer a limitation on the number of communication telegrams recorded as in the related art.

(2) The control unit automatically transfers the communication message stored in the storage unit under a predetermined condition from the storage unit to the external storage device without the intervention of an operator and stores the communication message. This eliminates the need for the operator to perform a complicated communication message transfer operation to the external storage device, thereby reducing the operator's work load.

(3) Further, the number of times of operation of the external storage device is reduced as compared with the related art, and the life of the external storage device (such as a magnetic disk device) can be improved as compared with the related art.

(4) If a communication message in the storage unit is not stored at a predetermined time, a message indicating that there is no communication message is stored in the external storage device together with the time, and by confirming the external storage device, It can be confirmed that there is no communication message.
