FIG. 5 is a diagram illustrating a data transmission speed according to a bus line length in a can communication method, and FIG. 6 is a diagram illustrating a can communication FIG. 7 is a functional block diagram of a general-purpose connection device of a sewing machine addition function unit according to the present invention, FIG. 8 is a flowchart of a general-purpose connection method of a sewing machine addition function unit according to the present invention, FIG. 9 is a diagram showing a state of command signal configuration by icon program input and placement according to an embodiment of the present invention.

In describing an example of the present invention, since illustration and description of a well-known technical content which is not directly related to the present invention are omitted, the present invention is clearly conveyed without blurring the gist of the present invention.

CAN (CAN) communication method developed and standardized by BOSCH of Germany is a kind of SERIAL COMMUNICATION PROTOCOL applying ISO 11898 international standard, It is a data transmission rate and noise resistant protocol.

Such a can communication method is divided into a multi master system of broadcast (BROADCAST) which broadcasts data generated by each control unit constituted to other control units, a dual connection system of dual line connection (DUAL WIRE) scheme, it has advantages such as excellent reliability and stability of data transmission and excellent error detection and processing performance.

The first to N-th CAN units 80, 80A and 80N are connected to the control units 81, 81A and 81N and the protocol units 83, 83A and 83N, respectively, And is connected in parallel to a bus line (BUS line) or a communication line using two lines of twisted lines (TWIST LINE), and includes transmission and reception units 85, 85A and 85N, And the N-th can units 80 and 80N connect the load resistance to the bus line in parallel.

The bus line 90 is a twisted line because it keeps the twisted-pair communication line consisting of the first communication line 91 and the second communication line 92 in a constantly twisted state, It serves to reduce noise.

The cause of the noise in the line is the electrostatic induction noise due to the capacitance between the lines and the electromagnetic induction noise due to the inductance of the line. By twisting these lines, the polarity of the capacitance is changed and canceled each other, and the electromotive force is canceled to reduce the noise.

The data transmission speed in the CAN communication method differs depending on the length of the bus line 90. Data transmission of about 1 Mbps is possible in the case of 40 meters and data transmission of about 500 Kbps in the case of 100 meters And data transmission of about 50 Kbps is possible in the case of 1 kilometer, and the data transfer rate according to the bus line length in the CAN communication is as shown in FIG.

The bus line 90 is a line to which the data is to be transmitted. Since the transmission speed varies depending on the length of the data, the data line should be configured within 40 meters to maintain a data transmission rate of 1 Mbps, and a REPEATER should be used if it is 1000 meters or more.

Referring to FIG. 6, the voltage level of the digital data 0 and 1 according to one example of the can communication method will be described. When 2.5 volts (V) is detected on the bus line 110, digital data "1 & 0 "if 3.5 volts (V) and 1.5 volts (V) are simultaneously detected from either one of the first communication line 111 of the first communication line 110 or one of the lines of the second communication line 112. [ Therefore, in the CAN communication system, when either the first communication line 111 or the second communication line 112 constituting the bus line 110 is disconnected, normal communication is not performed.

CAN communication is a system in which a plurality of control units or ECUs (an electronic control unit) are connected in parallel to transmit and receive data. Each control unit continuously transmits data to another control unit, and data transmitted from another control unit There is an advantage that a large amount of data can be shared by receiving and performing required processing.

That is, the can communication is a method in which data is loaded on the bus line 110, which is a communication line, and necessary data is fetched and used. Since the method is a method of reading data with a voltage difference between the first communication line 111 and the second communication line 112, If any one of the communication lines is disconnected, communication is impossible.
