Further, the CPU 8 drives and controls various actuators 15 such as a spindle motor, an X-axis motor of an embroidery frame, and a Y-axis motor via a driver 14 according to a sewing program set in advance or appropriately. Sewing is performed. At that time, the CPU 8 writes actual work data of sewing (including work contents and date and time of sewing) in the RAM 10. The work data is as shown in FIG.
[0015]
The control unit 7 is provided with security in order to prevent unauthorized intrusion from the Internet 3.
[0016]
As shown in FIG. 3, the computer 4 is mainly composed of a CPU 16, a ROM 17, and a RAM 18. In addition, a communication interface for communicating with the Internet 3 via the Internet 3 and the telephone line 5. (I / F) 19, an input / output port 20, a display 21 such as a CRT display, a keyboard 22, a mouse 23, and a floppy disk driver 24.
Here, each of the sewing machines 1A, 1B,... Has a sewing machine number, for example, “00000001”, “00000002”,.
[0017]
In the information transmission system of the sewing machine having the above configuration, a program for information transmission is stored in the computer 4, and a program for information transmission is also stored in the control unit 7 of the sewing machines 1A, 1B. Has been. 2 shows a flowchart of a program for information transmission in the computer 4. For example, when a sewing machine number, operation command, and date information of a sewing machine requiring information are input by key operation from the keyboard 22, these are stored and saved (set) (steps P1, P2, and P3). Then, it is determined whether or not information has been transferred from the sewing machine (step P4). That is, a transfer standby state is entered. If there is a transfer, the information is read (step P5). Thereafter, the stored sewing machine number is deleted (step P6).
[0018]
Among the sewing machines 1A, 1B,..., A flowchart of a program for information transmission in the control unit 7 of the sewing machine 1A is shown in FIG. First, the current time by the soft timer is read (step S1), and it is determined whether or not a preset time, for example, 0: 0 is reached. At 0:00, based on the address of the computer 4 stored in the ROMs 15 and 16 as its own memory, the computer 4 is accessed via the server of the Internet 3 to read the sewing machine number (step S3). Then, it is determined whether or not the read sewing machine number matches the own sewing machine number (step S4).
[0019]
If the read machine number matches the own machine number, the command is read (step S5). Then, it is determined whether or not the command is an information transfer command (step S6). If the command is an information transfer command, date information is read (step S7). Then, the sewing machine information (FIG. 6) relating to the corresponding date is transferred to the computer 4. For example, in the case of the sewing information on February 2, 2001 (specific data among the data held by the sewing machine), the sewing information corresponding to February 2, 2001 is transferred in FIG.
[0020]
FIG. 7 shows a sequence of information transfer with the sewing machine 1A and the computer 4. As will be understood, when the sewing machine 1A confirms that the time is “0: 0”, the sewing machine number is read from the addressed (specific) computer 4 via the Internet 3. When the sewing machine number matches the sewing machine number “00000001” of the sewing machine 1A itself, the command is read out. Thereafter, processing corresponding to the command is performed. That is, when the command is transfer of date-designated sewing information, the date data is read and the sewing information of the specified date of the sewing machine 1A itself is transferred to the computer 4. The computer 4 deletes the stored sewing machine number.
The other sewing machines 1B,... Have their own sewing machine numbers and perform the same operation as the sewing machine 1A.
[0021]
As described above, according to this embodiment, the sewing machines 1A, 1B,... Read the sewing machine number of the computer 4 via the Internet 3, and if the sewing machine number matches the sewing machine number of the sewing machine 1A, 1B,. The process corresponding to the command is executed. In this case, since the sewing machine itself does not access the sewing machine from the computer 4 via the Internet 3 but reads it from the computer 4, there is no problem even if security protection is set.
[0022]
Further, according to the present embodiment, since the data transmitted from the sewing machine is limited data such as specific data, the computer 4 can obtain only necessary data and is practical.
[0023]
Further, according to the present embodiment, since the command given to the sewing machines 1A, 1B,... Is a work data transfer command, the computer 4 can obtain the work data of each sewing machine 1A, 1B,.
[0024]
In the above embodiment, the control unit 7 periodically reads the sewing machine number, but this may be caused by some factor, for example, the operator accessing the computer by operating a keyboard or a switch. You may make it do. Alternatively, the computer may be accessed when an internal factor such as an abnormality in the sewing machine occurs.
