Fig. 1 illustrates a schematic diagram of a scenario where a warm-up system 100 is applied according to an embodiment of the present invention. The warm-up system 100 includes a processor 110, a storage medium 120, a transceiver 130, and an input/output device 140. The warm-up system 100 may be communicatively connected to one or more processing machines (for example, the processing machine 210 or the processing machine 220) through the transceiver 130 to automatically perform a warm-up program or a processing program on the processing machine. The warm-up system 100 can also be communicatively connected to the sensor 300 for sensing the machine status information of the processing machine through the transceiver 130. It should be noted that the warm-up system 100 can be used to manage any number of processing machines, and the present invention is not limited to this.

The processor 110 is coupled to the storage medium 120, the transceiver 130 and the input/output device 140. The processor 110 is, for example, a central processing unit (CPU), or other programmable general-purpose or special-purpose micro control unit (MCU), microprocessor, or digital signal processing DSP (digital signal processor, DSP), programmable controller, application specific integrated circuit (ASIC), graphics processing unit (GPU), arithmetic logic unit (ALU) , Complex programmable logic device (CPLD), field programmable gate array (FPGA) or other similar components or combinations of the above components.

The storage medium 120 is, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), or flash memory (flash memory). , Hard disk drive (HDD), solid state drive (SSD) or similar components or a combination of the above components, which are used to store multiple modules or various application programs that can be executed by the processor 110. In this embodiment, the storage medium 120 can store multiple modules including a work order management module 121, an automatic update module 122, a processing program management module 123, a warm-up module 124, and a performance index module 125. The function will be explained later.

The transceiver 130 transmits or receives signals in a wireless or limited manner. The transceiver 130 may also perform operations such as low noise amplification, impedance matching, frequency mixing, up or down frequency conversion, filtering, amplification and the like. The processor 110 of the warm-up system 100 may be communicatively connected to the processing machine 210 (or the processing machine 220) through the transceiver 130 to control the processing machine 210 to execute the warm-up program or the processing program.

The input and output device 140 is, for example, a computer, a keyboard, a mouse, or a display (or a touch display), etc., but the invention is not limited thereto. The input and output device 140 can generate work order scheduling information according to the user's operation, and transmit the work order scheduling information to the processor 110. On the other hand, the input/output device 140 can also display the data provided by the warm-up system 100 to the user for reference.

The sensor 300 is, for example, a thermometer or an electric meter. The processor 110 can be communicatively connected to the processing machine 210 and the sensor 300 corresponding to the processing machine 210 through the transceiver 130 to obtain the machine status information of the processing machine 210. The machine status information may come from the processing machine 210 or the sensor 300, and may include the spindle load, spindle speed, temperature, current and voltage, time-domain amplitude waveform, warm-up time or operating status of the processing machine 210. But the present invention is not limited to this.

FIG. 2 shows a flowchart of a warm-up method according to an embodiment of the present invention, wherein the warm-up method can be implemented by the warm-up system 100 shown in FIG. 1. In step S210, the user can upload a warm-up program or processing program to the warm-up system 100, where the warm-up program is used to execute the warm-up program for the processing machine 210 (or the processing machine 220), and the processing program is used to The processing program for the processing machine 210 (or the processing machine 220) is executed. Since there may be differences between different processing machines, the warm-up program or processing program corresponding to the processing machine 220 and the warm-up program or processing program corresponding to the processing machine 220 may be different. In some embodiments, the warm-up program or processing program can be obtained by connecting the warm-up system 100 to a cloud server through the transceiver 130.

In step S220, the work order management module 121 of the warm-up system 100 can obtain work order scheduling information. The work order scheduling information is, for example, input by the user to the warm-up system 100 through the input and output device 140. Work order scheduling information may include information such as work order name, processing program name, warm-up program name, estimated warm-up time interval, machine startup time, warm-up program startup time, or machine identification code, but the invention is not limited to this .

In step S230, the automatic update module 122 of the warm-up system 100 can identify the corresponding processing machine based on the work order scheduling information. Specifically, the automatic update module 122 can determine that the work order scheduling information corresponds to the processing machine 210 or the processing machine 220 from the machine identification code in the work order scheduling information. If the automatic update module 122 determines that the machine identification code corresponds to the processing machine 210, the flow proceeds to step S240, and the warm-up system 100 starts to warm up the processing machine 210 (or “first processing machine”). On the other hand, if the automatic update module 122 determines that the machine identification code corresponds to the processing machine 220 (or “the second processing machine”), the flow proceeds to step S250, and the warm-up system 100 starts to perform the processing on the processing machine 220 Warm up.

Fig. 3 further illustrates a flowchart of step S240 of the warm-up method according to an embodiment of the present invention. In step S241, the automatic update module 122 reads the content of the work order scheduling information. In step S242, the automatic update module 122 determines the corresponding warm-up program according to the work order schedule information. Specifically, the automatic update module 122 can determine whether the corresponding warm-up program is available according to the name of the warm-up program in the work order schedule information. For example, the automatic update module 122 can access the storage medium 120 to obtain a warm-up program. If the storage medium 120 does not store the warm-up program, the automatic update module 122 determines that the warm-up program is not available, and the process proceeds to step S251. In step S251, the processor 110 may send an abnormal report through the input/output device 140 for the user's reference based on the unavailability of the warm-up program. Conversely, if the automatic update module 122 determines that the warm-up program is available, the flow proceeds to step S243.

In step S243, the automatic update module 122 loads the warm-up program based on the available warm-up program. Specifically, the automatic update module 122 can load the corresponding warm-up program into the warm-up module 124 and the processing machine 210 according to the name of the warm-up program in the work order schedule information. In some embodiments, the processing program management module 123 can manage the version of the warm-up program (or the processing program used in step S250). For example, the processing program management module 123 can connect to a cloud server through the transceiver 130, so as to update the warm-up program (or processing program) in the storage medium 120 by accessing the cloud server. Since there may be differences between different processing machines, the processing program management module 123 can refer to the machine identification code to manage the warm-up program or the version of the processing program.

In step S244, the processor 110 determines whether the time setting information is correct according to the work order scheduling information. Specifically, the processor 110 can determine the time setting information such as the machine startup time, the warm-up program startup time, or the expected warm-up time interval set in the work order schedule information based on the schedule data pre-stored in the storage medium 120 is it right or not. For example, if according to the factory rules (which can be pre-stored in the storage medium 120), the startup and warm-up procedures of the processing machine 210 can only be executed in the morning, the processor 110 can be based on the work order schedule information The set machine start time or warm-up program start time corresponds to the afternoon time period and the time setting information is judged to be incorrect. For another example, if the warm-up time interval of the processing machine 210 cannot exceed three hours according to the rules of the factory, the processor 110 may set the expected warm-up time interval based on the work order schedule information to exceed three. Hour and judge the time setting information is incorrect.

If the processor 110 determines that the time setting information is correct, the process proceeds to step S245. Conversely, if the processor 110 determines that the time setting information is incorrect, the flow proceeds to step S251. In step S251, the processor 110 may send an abnormal report through the input/output device 140 for the user's reference based on the time setting information error.

In step S245, the processor 110 activates the processing machine 210 according to the work order scheduling information. Specifically, the processor 110 may activate the processing machine 210 at a corresponding time point according to the machine start time in the work order scheduling information.

In step S246, the processor 110 determines whether the activation of the processing machine 210 is smooth. If the starting of the processing machine 210 is smooth, the flow proceeds to step S247. Conversely, if an abnormality occurs in the startup of the processing machine 210, the flow proceeds to step S251. In step S251, the processor 110 may issue an abnormal report through the input/output device 140 for the user's reference based on the abnormality in the startup of the processing machine 210.

In step S247, the warm-up module 124 determines whether to start the warm-up procedure. Specifically, one or more sensors for detecting on-site information can be arranged around the processing machine 210. The warm-up module 124 can receive the on-site information generated by the sensors through the transceiver 130, and determine whether to start the warm-up procedure based on the on-site information. If the on-site information indicates that no person is on-site (ie, near the processing machine 210) or indicates that no foreign matter affects the processing machine 210, the process proceeds to step S248. Conversely, if the on-site information indicates that a person is on-site or a foreign object affects the processing machine 210, the process proceeds to step S251. In step S251, the processor 110 may indicate that a person is on-site or a foreign object affects the processing machine 210 based on the on-site information, and send an abnormal report through the input and output device 140 for the user's reference.

…公式（1） In step S248, the warm-up module 124 activates the warm-up procedure corresponding to the processing machine 210 according to the work order schedule information. In step S249, the performance index module 125 calculates the warm-up performance index of the processing machine 210 according to the machine status information. Specifically, during the execution of the warm-up procedure, the machine status information of the processing machine 210 will change. Therefore, after the warm-up procedure is started, the performance index module 125 can calculate the warm-up performance index of the processing machine 210 based on the machine status information. The performance indicator module 125 can display warm-up performance indicators and/or machine status information for the user's reference through the input and output device 140. The user can judge the warm-up progress of the processing machine 210 according to the warm-up performance index. The warm-up performance index is, for example, a function related to at least one of the following parameters: spindle load, spindle speed, temperature, current and voltage, time domain amplitude waveform, warm-up time, and operating state. The performance index module 125 can also calculate the historical warm-up performance index average Pn according to the following formula (1), where "i" represents the time index, "Pi" represents the warm-up performance index at time i, "K" Represents the number of historical warm-up performance indicators.

…Formula 1)

In step S250, the warm-up procedure is completed. After the warm-up procedure is completed, the processor 110 may further start the processing procedure of the processing machine 210 according to the work order scheduling information. Specifically, the automatic update module 122 loads the corresponding processing program into the processor 110 and the processing machine 210 according to the processing program name in the work order scheduling information, so that the processor 110 and the processing machine 210 can be based on The processing program performs processing procedures to produce processed products.

…公式（2） FIG. 4 illustrates a schematic diagram of a comparison between the processing flow S410 using the warm-up system 100 and the traditional processing flow S420 according to an embodiment of the present invention. It can be seen from this embodiment that the utilization rate of the processing flow S410 using the warm-up system 100 will be significantly higher than the utilization rate of the traditional processing flow S420. The calculation method of the utilization rate is as shown in formula (2), where "UR" represents the operation Rate, "Tt" represents the available operating time of the processing machine. Specifically, "Tt" is the maximum operating time of the processing machine minus the downtime loss, where the downtime loss is the expected rest time, such as related to factors such as employee vacation, employee education and training, or machine maintenance. "Tc" represents the available operating time of the processing machine minus the line stop time, where the line stop time is the unexpected rest time, such as factors related to batch conversion and process abnormality, abnormal stop of the processing machine or repair of the processing machine.

…Formula (2)

Referring to Fig. 4, it is assumed that the working time of the processing personnel is 9:00. The processing flow S410 using the warm-up system 100 may perform the warm-up procedure before the operating time. In step S411, the warm-up system 100 can set the warm-up program, estimated warm-up time interval, machine start time, or warm-up program start time of the processing machine (assuming processing machine 210) according to the work order schedule information. parameter. In step S412, the warm-up system 100 loads the warm-up program into the processing machine 210. In step S413, the warm-up system 100 performs a warm-up program of the processing machine 210. The warm-up procedure takes less than 30 minutes. Therefore, the warm-up procedure from 08:30 can be completed before the working time (ie: 9:00). In step S414, the processing personnel start the operation test of the processing machine 210 at 09:00. Next, in step S415, the processing personnel can start processing and production using the processing machine 210 at 09:15.

Relatively speaking, the traditional processing process S420 can only start when the processing personnel arrive at the site. In step S421, the processing personnel arrive at the site where the processing machine (assuming the processing machine 220) is located at 09:00. In step S422, the processing personnel manually start the warm-up program of the processing machine 220 at 09:15. At this time, the processing flow S410 has already entered the step of processing and production (ie, step S415). In step S423, the processing machine 220 completes the warm-up procedure at 09:30. In step S424, the processing personnel manually select the processing program applied to the processing machine 220. In step S425, the processing staff manually loads the processing program into the processing machine 220. In step S426, the processing personnel starts the operation test of the processing machine 220. If the processing personnel selects an unsuitable processing program in step S424, step S426 will fail. The processing personnel need to perform step S424 again. Even if the processing personnel smoothly select the most suitable processing program for the first time, the processing machine 210 must wait until 10:00 to start processing and production in step S427.

Table 1 is a comparison table of the utilization rate of processing flow S410 and traditional processing flow S420. It can be seen from Table 1 that the processing flow S410 using the warm-up system 100 reduces the waiting time by about a quarter compared with the traditional processing flow S420, and the processing time is also increased by 45 minutes. The utilization rate of the processing flow S410 is about 10% higher than that of the traditional processing flow S420, and the completed number of processed products is also three more. Table 1 waiting time Processing time Total machine running time Utilization rate Amount completed Processing flow S410 15 minutes 465 minutes 480 minutes 96.875% 31 pieces Traditional processing flow S420 60 minutes 420 minutes 480 minutes 87.5% 28 pieces

The warm-up performance index is used to evaluate the warm-up performance of the warm-up program for the processing machine. For example, suppose that the processing machine using the warm-up system 100 (assuming the processing machine 210) has five different warm-up programs (warm-up programs W1, W2, W3, W4, and W5), and the processing machine 210. Use different warm-up programs to warm up the engine from Monday to Friday. The performance index module 125 can respectively calculate the daily warm-up performance indexes, as shown in Table 2, where the warm-up time represents the time it takes for the bearing temperature of the processing machine 210 to reach the processing temperature. In this embodiment, the warm-up performance index of the warm-up program W4 is the highest, and only 25 minutes of warm-up time are required. The warm-up program W3 has the lowest warm-up performance index, which takes 50 minutes to complete the warm-up. Table 2 W1 W2 W3 W4 W5 Warm-up performance index 70 80 60 85 65 Warm-up time 40 minutes 30 minutes 50 minutes 25 minutes 45 minutes

Table 3 shows the processing efficiency analysis using each warm-up program. Assuming that the total running time of a processing machine (for example, processing machine 210) is 8 hours, it takes 15 minutes to produce a single processed product. It can be seen from Table 3 that the warm-up time consumed by the warm-up program W4 is the shortest, and its utilization rate is the highest, and the completed number of processed products is also the largest. The warm-up program W3 takes the longest warm-up time, and its utilization rate and the completed quantity of processed products are the least. table 3 W1 W2 W3 W4 W5 Warm-up time 40 minutes 30 minutes 50 minutes 25 minutes 45 minutes Processing time 440 minutes 450 minutes 430 minutes 455 minutes 435 minutes Total machine running time 480 minutes 480 minutes 480 minutes 480 minutes 480 minutes Utilization rate 91.6% 93.75% 89.58% 94.79% 90.62% Amount completed 29 pieces 30 pieces 28 pieces 30 pieces 29 pieces

Through the above analysis, if the processing personnel select the warm-up program W4 that is most suitable for the processing machine 210 based on the warm-up performance index, it can increase the utilization rate by about 5% compared with the warm-up program W3 with the worst warm-up performance, and Complete more processed products.

In summary, the present invention provides a user input and output device to enter work order scheduling information, and the warm-up system can automatically identify the processing machine to be used and its warm-up procedure or processing procedure based on the work order schedule information. . In this way, it can solve the traditional manufacturing industry using paper for work order scheduling management, reduce paper waste and achieve the purpose of increasing scheduling efficiency and transparency of processing information. In addition, the version of the processing program of the warm-up system can be automatically updated. Since the version of the processing program will no longer require manual maintenance, the probability of using the wrong version of the processing program can be reduced, and the cost of maintaining the processing program can be reduced. The warm-up system can also identify the processing machine and automatically synchronize the processing program through the processing program name and the machine identification code, so that the processing program can be synchronized to the processing machine in advance. The processing program will no longer need to be updated, compared or installed manually, which can reduce the probability of using the wrong processing program, the time for manual comparison of the processing program, and the consumables used for running test runs.

The warm-up system can arrange the warm-up procedure and the start time of the processing procedure according to the work order schedule information. After the processing machine is started, the warm-up system can combine the sensing data of the sensor to determine the machine status information of the processing machine in the warm-up. Machine status information can provide processing personnel with information such as spindle load, spindle speed, temperature or current and voltage. Processing personnel can use the machine status information to evaluate the efficiency of the warm-up procedure implemented on this processing machine and assist processing personnel in filling out work orders in the future Refer to the scheduling information to solve the problem of long warm-up time caused by improper warm-up program selected by the processing staff.

The warm-up system can start the warm-up procedure only after judging that there are no personnel on site or no foreign matter affecting the machine. Since personnel do not need to be on site, they can also perform the warm-up procedure of the processing machine at any time, so the utilization rate of the processing machine can be significantly improved and the safety of the workshop can be improved.
