The magnet 120 may be configured to be fixedly attached to the end of the needle bar 130.

Needle bar 130 is a configuration to which the needle 110 is attached.

In the needle bar 130, the needle bar 130 moves up and down by a sewing machine, so that the needle moves up and down to sew. The handle on the right side of the sewing machine transmits power by manual rotation to the needle bar 130 so that the needle bar 130 moves up and down.

The needle bar 130 has a hollow shape at the other end, and a magnet may be inserted into the hollow shape to be fixedly attached.

The magnetic sensor 140 is attached to the body of the sewing machine itself, and may be attached to the upper portion of the space where the needle bar 130 is installed in the sewing machine.

The magnetic sensor 140 may be configured to sense the magnet 120 fixedly attached to the other end of the needle bar 130 whenever the needle bar 130 moves up and down. The up and down motion of the magnet 120, that is, the needle bar 130 may be sensed by using a change in the intensity of the magnetic force of the magnet 120.

The work information collecting module 150 may be configured to collect work information according to up and down motion sensed by the magnetic sensor 140. The operation information may be composed of the number of movements of the needle bar 130 up and down, the position information according to the vertical motion of the needle bar 130, and the like.

The method of detecting the position of the needle bar 130 is that the magnet sensor 140 and the magnet 120 fixed to the needle bar 130 are closer to each other as the needle bar 130 is moved upward. ) Is a position that detects the needle bar up position, and a position where the magnet 120 is not detected by the magnet sensor 140 becomes a needle bar down position.

In addition, the work information collecting module 150 may also determine and collect whether the needle bar 130 is in a stopped state. Specifically, if the detection signal of the magnetic sensor 140 is unchanged for a certain period of time, it may be determined that the motion is stopped.

Normally, if there is no change in the detection signal for about 0.5 seconds, it may be determined that the motion is stopped.

The work information collection module 150 may collect the number of movements of the needle bar 130 up and down and the position information according to the up and down motion of the needle bar 130 in correspondence with the ID of the sewing machine.

Here, the operation information according to the vertical movement, needle bar up position stop (needle bar up position stop) information, which is a stop position at the upper position of the needle bar 130, the needle bar lower position, which is a stop position at the lower position of the needle bar 130 It may be configured to include at least one of stop bar (needle bar down position stop) information, stop time information.

In addition to this, it may be configured to further include at least one of the position stop information on the needle bar, the waiting time information of the sewing operation according to the needle bar position stop information, the machine operation time information, or the stitch number of stitches.

The job information transmitting module 160 may be configured to transmit the job information collected by the job information collecting module and the ID of the corresponding sewing machine to the server 10 or the user terminal 20 in a wireless communication or wired communication method.

The operation information of each sewing machine of the server 10 or the user terminal 20 may be collected and managed.

Hereinafter, the details of the operation information of the sewing machine, that is, the machine will be described in more detail with reference to FIGS. 7 and 8.

The machine operation information is information obtained from a sewing machine, that is, a sewing machine and transmitted to the server 10, and is composed of sum table information and sequence table information. The work information collection module 150 periodically collects the standby time, the machine operating time, the number of stitches, the pause time and the needle bar stop position information by periodically analyzing the needle bar position information, and sums the table information and the sequence table when it is determined that the sewing is finished. Each is stored in information.

7 is a configuration diagram of machine operation information according to an embodiment of the present invention.

Referring to FIG. 7, the machine operation information is composed of sum table information and sequence table information. The sum table information is divided into a plurality of areas, and may include data of a count, a total number of stitches, a total waiting time, a total machine operating time, and a total pause time in each area. The sequence table information has a storage space of a predetermined size, and may include data of a waiting time, sewing stitch number, machine operation time, stop position, and pause time.

The summation table information, when the end of sewing is confirmed, finds the area of the stitch number in the table and adds the number of stitches to the total number of stitches, the waiting time, the pause time, and the machine running time. After adding up to the time and the total machine running time, the count information of the area is increased by one.

When the stoppage of the sewing is confirmed, information on the number of stitches and waiting time, the machine operation time, the stop position, and the pause time may be additionally input in the sequence table information. When the additional input exceeds the allowable storage capacity, data can no longer be stored, or it can be configured to keep the data capacity at a constant size by updating and storing the latest data in the oldest data. After the job information transmitting module 160 transmits the above data to the server 10 or the user terminal 20, the job information collecting module 150 may be configured to erase all the sequence tables and store the information again from the beginning. have.

8 is a view for explaining a change in the position information of the needle bar with respect to time according to an embodiment of the present invention and its interpretation method.

As illustrated in FIG. 8, if the x-axis of the graph is set to time and the y-axis is set to the needle bar position signal, the waiting time, machine operating time, pause time, and sewing stitch number can be analyzed according to the change of the needle bar position signal. In FIG. 8, a low level section of the needle bar position signal means that the needle bar 130 is in a position on the needle bar, and a high level section means that the needle bar 130 is in a position below the needle bar. Depending on the actual implementation, the low level and the high level may be opposite to each other.

The update of the work information is made when the end conditions of sewing are satisfied. The end of sewing can be determined by analyzing the holding time of the needle bar signal. For example, the end of sewing may be the end of sewing if the position signal on the needle bar is maintained for 2 seconds. As another example, if the position signal under the needle bar is maintained for 1 second, sewing may be terminated. As another example, if the needle bar top or bottom position signal is maintained for 3 seconds, sewing may be terminated.

When the end condition of sewing is satisfied, it may be configured to update the work information. When updating the sum table information, after finding the area corresponding to the number of stitches to be stitched, the waiting time, machine operation time, sewing number, and pause time are added to the total waiting time, total machine operation time, total sewing number, and total pause time. Then, the counter value of the corresponding area is increased by 1.

In order to update the sum table information, the pause time and the wait time may be set to the set time limit to the maximum value. That is, when the set time limit is 1 minute, even if the pause time or the waiting time exceeds 1 minute, the time may be limited to 1 minute to update the information. This is so that the time for the worker to stop for rest is not included except for the time for the worker to work.

The sequence table information may be configured to store no more data or delete the oldest data and store the latest data to maintain a constant data capacity when the data exceeds the allowable storage capacity when inputting the data. . After transmitting data to the server 10, it may be configured to erase all sequence table information and store the information from the beginning.
