[Determination table settings]
Next, regarding the determination table that the control unit 201 in the host computer 200 refers to as determination criteria when determining which one of the looms 300 is to be repaired preferentially when two or more looms 300 are stopped. , with reference to FIG.

FIG. 5 is an explanatory diagram illustrating a setting example of the determination table according to Embodiment 1 of the present invention. The determination table contains a plurality of determination items, determination conditions for each of the plurality of determination items, and a plurality of determination criteria for determining which one of the looms 300 to repair when two or more looms 300 fail. Judgment order for executing judgment by item is defined.

In the determination table illustrated in FIG. 5 , the plurality of determination items, the determination conditions of each of the plurality of determination items, and the determination order for performing determination based on the plurality of determination items are as follows.

As determination items, for example, the product type, machine number, travel time, cause-specific repair time, total repair time, stoppage time threshold, and stoppage time length can be determined.

A specific example of the determination table in FIG. 5 is as follows.
- In the first judgment order, the product type A is given priority as the judgment item: type.
- In the second judgment order, machine Nos. 3001, 3206, and 3303 are prioritized as judgment items: machine numbers.
・In the third order of judgment, priority is given to the shortest time required for the weaver to move to the repair destination as the judgment item: travel time. Note that the moving time is a relative value of the moving times within the plurality of looms 300, and is not limited to absolute hours, minutes, and seconds.
・In the fourth judgment order, judgment item: repair time by cause, (vertical, horizontal, manual, discarded ear, other) = (10, 3, 5, 7, 1), and stop due to short repair time priority is given to the Note that the repair time is a relative value for each cause, and is not limited to absolute hours, minutes, and seconds.
- In the fifth judgment order, judgment items: total repair time = travel time + repair time by cause are set so that the shortest time is prioritized.
- In the sixth judgment order, judgment item: 20 minutes as the threshold, and priority is given to those longer than 20 minutes as the threshold.
・In the seventh judgment order, the judgment item is set to give priority to the one with the longest stop time.

Another setting example of the determination table will be described with reference to FIG. FIG. 6 is an explanatory diagram illustrating a setting example of the determination table according to Embodiment 1 of the present invention. A specific example of the determination table shown in FIG. 6 is set as follows.
- In the first judgment order, as the judgment item: machine number, the 3001 machine is set as the first priority, and the 3206 and 3303 machines are set as the second priority.
- In the second judgment order, as the judgment item: kind, the kind A and the kind C of the products are set as the first priority, and the kind D is set as the second priority.
- In the third judgment order, judgment item: total repair time = travel time + repair time by cause is set so that the shortest time is prioritized.

As shown in FIGS. 5 and 6 above, the plurality of judgment items, the judgment conditions for each of the plurality of judgment items, and the judgment order for executing the judgment based on the plurality of judgment items in the judgment table are determined by the textile machine system 1. The manager or person in charge can arbitrarily set it.

[Calculation of travel time]
Next, the calculation of the travel time required for the weaver 10 as the worker to move to the repair destination will be described with reference to FIG. FIG. 7 is an explanatory diagram illustrating movement of a worker in the textile machine system 1 according to Embodiment 1 of the present invention.

Here, six looms 0 to 5 are arranged in the X direction, and six looms 0 to 5 are arranged in the Y direction. , 3401 to 3406, and 3501 to 3506 are arranged.

The position of the weaver 10 includes the position of the loom 300 to which the loom 10 has transmitted the repair completion, the position of the loom 300 to which the loom 10 has transmitted the instruction request, and the position determined by the terminal or RFID possessed by the loom 10. The host computer 200 determines either one or a combination thereof.

In FIG. 7, the weaver 10 is assumed to be at coordinates (Xs, Ys)=(0,0). The travel time Tm for the weaver 10 to move from the coordinates (Xs, Ys) to the coordinates (Xm, Ym) of each of the looms 300 can be calculated as follows. If the moving speed of the weaver 10 is constant, the moving time is proportional to the moving distance, so it is calculated as the moving distance of the path.

In the loom 300 of FIG. 7, the X direction is three times as large as the Y direction, so the coefficients ωx and ωy are set as (ωx, ωy)=(3, 1).
Therefore, the travel time Tm is
Tm=ωx|Xm−Xs|+ωy|Ym−Ys|
can be calculated as Note that the passage width is not considered here.

The travel time Tm for the weaver 10 positioned at coordinates (0, 0) to travel to the loom 300 at each position is as follows. The travel time Tm may be calculated using a relative value for determination, and is not limited to absolute hours, minutes, and seconds.
Machine number: Time Tm (3103) to move to 3103 is
Tm(3103)=3|1-0|+1|2-0|=5.
Machine number: Time Tm (3206) to move to 3206 is
Tm(3206)=3|1-0|+1|5-0|=8.
Note that 3103 and 3206 are the same path and have the same Xm.
Machine number: Time Tm (3302) to move to 3302 is
Tm(3302)=3|3-0|+1|1-0|=10.
Machine number: Time Tm (3405) to move to 3405 is
Tm(3405)=3|3-0|+1|4-0|=13.
Note that 3302 and 3405 are the same path and have the same Xm.
As a result, when the determination item is the travel time, the priority is 3103>3306>3202>3405. Further, it is also possible to make detailed calculations by considering the width of the path, the height difference, and the orientation of the loom 300 .

[Example of judgment based on repair time by cause]
Here, a specific example of calculation and determination of the repair time for each cause shown in FIG. 5 will be shown. The recovery time by cause is a relative value of the recovery time required for each cause, and is not limited to absolute hours, minutes, and seconds.
Assume that the cause of stoppage of machine number: 3103 and machine number: 3206 is "vertical", and the cause of stoppage of machine number: 3302 and machine number: 3405 is "horizontal". In this case, repair time by cause for machine number: 3103 = 10, repair time by cause for machine number: 3206 = 10, repair time by cause for machine number: 3302 = 3, repair time by cause for machine number: 3405 = 3 , is.
As a result, in the case of determination by the determination item: recovery time by cause, the priority is 3302=3405>3103=3206.

[Example of determination based on total repair time]
Here, a specific example of calculation and determination of the total repair time will be shown. Machine number: 3103 total repair time = 5 + 10 = 15 Machine number: 3206 total repair time = 11 + 10 = 21 Machine number: 3302 total repair time = 10 + 3 = 13 Machine number: 3405 total repair time = 16 + 3 = 19.
As a result, the priority order is 3302>3103>3405>3206 when judged by the judgment item: total repair time.

In the determination table illustrated in FIG. 5, the host computer 200 makes determinations according to the determination order of product type, machine number, movement time, repair time by cause, total repair time, stoppage time threshold, and stoppage time length.

In the judgment table illustrated in FIG. 6, the host computer 200 makes a judgment in the judgment order of machine number, product type, and total repair time.

In the determination table, it is also possible to define different determination conditions for the same determination item so that the same determination item exists in a different determination order. For example, in the determination table of FIG. 6, the determination item: product type exists in the determination order 2, but further setting "determination order: 4, determination item: product type, determination condition: product type B, product type C" is set. is possible.

The host computer 200 determines one loom 300 to be repaired preferentially according to a predetermined criterion when the determination is not completed even after the determination is continued to the determination item with the lowest determination order in the determination table. Note that the predetermined criterion is, for example, determining the one with the lowest serial number among the two or more stopped looms 300 .

The host computer 200 notifies the loom 300 that has been determined to be repaired preferentially to the weavers who can start the repair work. The host computer 200 sends this notification to the operation unit 320 of the loom 300 that the weaver was in charge of repairing until just before, or to the terminal possessed by the weaver. If the location of the weaver is unknown at the time of this notification, the host computer 200 may use the operation units 320 of all the looms 300 to make a simultaneous notification, or use other notification means such as a public address system. may be used.

When receiving the repair start notification, the host computer 200 changes the state of the loom 300 for which repair has started according to the state transition diagram of FIG. Update the data in the table.

In the above description, the host computer 200 can execute any one of information reception, data update, judgment, determination, and notification while executing another process.

When the host computer 200 continues to manage the operation status of the loom 300, the above processes are repeatedly executed. When the host computer 200 stops the entire loom 300 under its control, the host computer 200 performs necessary stop processing and terminates the above processing.

In addition, by temporarily rewriting the determination table, it is possible to flexibly deal with temporary detailed requests and determine the loom 300 to be repaired.

According to the textile machine system 1 and the host computer 200 according to the first embodiment, when determining the loom 300 to be repaired, the operating or stopped state and the assignment of the person in charge of repairing each stopped loom 300 are clarified. This avoids duplicate assignments even when there are multiple weavers in the same area.

According to the textile machine system 1 and the host computer 200 according to the first embodiment, when determining the loom 300 to be repaired, when assigning the person in charge of repairing each stopped loom 300, the automatic repair function is provided. In the case of the loom 300, since the device itself is assigned to be in charge of repair and managed, it is possible to avoid assigning a weaver in charge of repair to the loom 300 having an automatic repair function.

[Other embodiments]
A modification of Embodiment 1 of the present invention will be described below.
In the above description, the loom 300 is used as a specific example of the textile machine, but the present invention is not limited to this. For example, instead of the loom 300, the first embodiment of the present invention may be applied to a spinning machine such as a ring spinning machine. If the first embodiment described above is applied to a spinning machine, the determination items for the textile machine may be not only the serial number but also each spindle in the case of the spinning machine.

In the above description, priority conditions are set in the determination table for determining the target to be repaired, but the present invention is not limited to this. For example, a non-priority condition may be set in the determination items. More specifically, it is possible to set the determination item: as the product type, the product type A is repaired first, and the product type F is repaired last among all the product types. Also, regarding the movement time and the repair time, it is possible to give priority to the longer time.

The weaver's job of transmitting the weaver's name or an identification signal from the loom 300 is input from the operation unit 320 of the loom 300, biometric authentication using fingerprints, iris, veins, etc., an ID card, RFID, or the like. The host computer 200 may perform authentication using various authentication techniques such as ID authentication. Also, the host computer 200 may recognize the weaver in charge of the repair from the repair pattern of the loom 300 or the like.

In addition, the host computer 200 analyzes the image of the surveillance camera that monitors the premises where the textile machine system 1 is present, and performs face authentication using facial images, appearance authentication using clothing and body shape, etc., The weaver may be recognized by various techniques such as gait recognition for identifying a person's individuality, various video analysis authentication for recognizing an individual, and the like. For biometric authentication, ID authentication, restoration pattern recognition, video analysis authentication, etc., various techniques other than the above specific examples may be employed, or a plurality of techniques may be used in combination.
