DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a communication means for reading and writing parameters stored in a sewing machine control device for controlling a sewing machine, a memory, and storing of read parameters in a specific memory bank and writing of write parameters. It comprises a selection means for reading from a specific memory bank and a display means for displaying the selected specific memory bank and the read / write status. When replacing multiple parameter groups that are frequently set in advance in each memory bank, parameters can be set for multiple sewing machines with simple key operations and in a short period of time. It will be significantly reduced. In addition, parameters indicating sewing conditions of a predetermined sewing machine can be collectively stored in a readout memory and can be collectively written to the other sewing machine control device. The contents of the control in the sewing state can be copied to another sewing machine control device.

Further, first communication means for reading and writing parameters stored in the sewing machine control device for controlling the sewing machine, and second communication means for reading parameters written by a personal computer or writing to a personal computer. Selecting means for storing a read parameter in a specific memory bank and reading a write parameter from the specific memory bank; selecting the specific memory bank and reading / writing;
It is composed of display means for displaying the connection status of the sewing machine control device.Especially, parameters can be easily edited on a personal computer.In addition, for example, the edited parameter group can be stored in a file in a floppy disk. This makes it possible to manage parameter groups according to many types of sewing machines and sewing products. Of these, several parameter groups that are relatively frequently used are previously stored in several memory banks by the second communication means. If stored, parameters can be set in the sewing machine control device by simple key operations of the sewing manufacturer.

An embodiment of the present invention will be described below with reference to FIGS.

[0010]

In FIG. 1, reference numeral 1 denotes a microcomputer (hereinafter referred to as a microcomputer) which internally has a ROM for a program memory and a RAM for a data memory, and selects, writes and reads parameters by a program. . Reference numeral 2 denotes a memory, a flash memory is used as a memory that can be stored even when the power is cut off, and the entire memory area is divided into a plurality of banks and a parameter group is stored in each bank. Reference numeral 3 denotes first communication means for performing bidirectional communication with the sewing machine control device 4, which is constituted by an IC circuit, and performs communication by an asynchronous serial communication method. Similarly, reference numeral 5 denotes a second communication means for performing asynchronous communication with a personal computer 6 (hereinafter, referred to as a personal computer), and is constituted by an IC circuit having an RS232C interface usually provided in the personal computer. Reference numeral 7 denotes a key, and reference numeral 8 denotes a display having 7-segment LEDs. As shown in FIG.
It is composed of five keys of "F", "M +", "M-", "B +", "B-" and two digits of LED.

The operation of the present invention configured as described above will be described below with reference to FIGS. 3 and 4 (a) and 4 (b).

FIG. 3 is a flow chart showing an operation for selecting a parameter. Mode selection and memory bank selection as shown in (Table 1) and (Table 2) are performed by key operation.

[0013]

[Table 1]

[0014]

[Table 2] As shown in Table 1, each time the keys "M +" and "M-" are pressed once, the mode changes in the direction of the arrow. As shown in (Table 2), the memory is divided into eight banks, each bank is indicated by a numerical value on the LED, and the keys "B +" and "B-" are set to one.
Each time the bank is pressed, the bank changes in the direction of the arrow. In particular, although the storage memory area of the parameter group of # 1 to # 8 stored in each bank is 256 bytes here, an area capable of storing all parameters of the sewing machine control device 4 is required.

When the key "SF" is continuously pressed twice a second in the state where the mode and the memory bank are selected as described above, communication in the selected mode is performed. It should be noted that this time may be set to any value as long as it can be distinguished that the determination is made twice consecutively.

Next, the communication operation according to each mode is performed by, for example, enabling the first communication means 3 when the reading mode from the sewing machine control device 4 is selected, as shown in FIG.
The parameters are read according to (a), and if writing to the sewing machine controller 4 is selected, the first
The communication means 3 is enabled, and parameters are written according to FIG. As a result, the operation of reading and writing parameters sequentially from the memory bank is performed. Here, the data structure is shown below.

Parameter number: Group number G--BCD code 2 digits (0 to 99) Function number F--BCD code 2 digits (0 to 99) Parameter value: Data D--BCD code 4 digits (0 to 9999) Description example: GF0101 = 0001 GF0106 = 0016 As described above, the individual parameters are:
The parameter numbers are sequentially stored and read out in a preselected memory bank in the form of parameter number = data.

Here, the determination as to whether or not the writing (reading) of all data has been completed includes a method using a code not used in communication, and a method in which data communication is not performed for a predetermined time and the method is regarded as being completed. Either method may be used.

In the above description, the reading / writing with the sewing machine controller 4 is performed.
Although the embodiment in which the first communication means 3 is enabled in the write mode has been described, the operation of communication with the personal computer 6 is, for example, the second communication when the read mode from the personal computer 6 is selected. FIG.
Parameter reading is performed according to (a), and when writing to the personal computer 6 is selected, the second communication unit 5 is enabled and parameter writing is performed according to FIG.

The second communication means 5 makes it possible to communicate with the personal computer 6 and to edit the parameters on the CRT of the personal computer, thereby facilitating the editing. In addition, for example, the edited parameter group is stored in the form of a file. Since it can be stored on a floppy disk, data management of parameter groups according to many types of sewing machines and sewing products can be performed on a floppy disk in the form of a file. If the groups are stored in advance in several types of memory banks by the second communication means 5, the parameters can be set in the sewing machine control device by a simple key operation of the sewing manufacturer, which has a great effect. Becomes

[0021]

As described above, according to the present invention, when changing the setting of the sewing machine, the parameter setting can be performed with a simple key operation and in a short time, and the labor of the operator is remarkably reduced. Become. Further, the contents of the sewing machine control device in the optimum sewing state can be easily copied to another sewing machine control device.

Further, it becomes possible to read and set several kinds of parameter groups, which are set particularly frequently from the personal computer, to several kinds of memory banks by means of communication with the personal computer. In addition, parameters can be easily edited on a personal computer, and for example, edited parameter groups can be stored on a floppy disk in the form of a file, so parameter groups can be managed according to many types of sewing machines and sewing products. Will be able to do above.
