Abstract

PURPOSE:To make it possible to discriminate many sewing-machines or motors from one input line, by a method wherein one resistance or a plurality of resistances are provided for a sewing machine or a motor, and by different values of these resistances, discriminating signals are outputted. CONSTITUTION:A sewing machine 4 is connected to an A/D conversion circuit 3 in a control device 1, and discriminating resistances R1, R2, R3 are equipped for the sewing machine 4. A motor 5 is also connected to the A/D conversion circuit 3 and resistances R4, R5 are equipped for the motor 5. A CPU 2 reads each voltage in an input line connected to each of input terminals AN1 to AN5. Reference voltage VR is divided by reference resistance RA and discriminating resistances R1 to R5, and each voltage divided from an electric source VN is applied to each of the input terminals AN1 to AN5. The CPU 2 reads each voltage and decides what each voltage is among a table previously provided on nonvolatile storage in the control device 1 and performs the establishment defined on the table for each voltage.

[Prior Art] Conventionally, as a device for identifying a plurality of control objects such as sewing machines or motors, each control object is provided with a logic signal output for identification of the control object having a logic unique to the control object, and the control device When the controlled object is connected and the power is turned on, automatic setting is performed by reading the logic signal (O or l) of the logic signal output line with the control device.

If the controlled object can have a microcomputer or complex logic circuit, it is possible to identify many types of controlled objects by outputting an accurate signal even with a single signal line. If the controlled object is a sewing machine or a motor, it does not have such a complicated circuit, so there are only two specifications that can be identified with one signal line: O and 1. Therefore, it is difficult to identify many specifications. Identification of complex specifications requires a large number of output lines, resulting in high costs and problems in that only simple settings are possible.

For this reason, such devices are not practical; many setting switches or volumes are installed in the control box, and settings are often made manually, which can lead to incorrect settings. Another problem is that a dedicated control box is often provided for the motor, making management complicated.
