In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

Please refer to FIGS. 1, 2 and 3. FIG. 1 is a functional block diagram of the tapping operation training system 100 according to an embodiment of the present invention, and FIG. 2 is a diagram showing the tapping operation training system 100 according to an embodiment of the present invention. A schematic top view of the structure of the bearing platform 200, and FIG. 3 is a schematic side view of the structure of the bearing platform 200 of the steel tapping training system 100 according to an embodiment of the present invention. The tapping operation training system 100 includes an operating mechanism 110, virtual reality (VR) glasses 120, a positioner 130, a computer system 140, and a bearing platform 200 (as shown in FIGS. 2 and 3).

As shown in Figure 1. The operating mechanism 110 is used for the user to operate the tapping operation, and transmits the user's operating data to the computer system 140. The virtual reality glasses 120 are used for the user to wear and present a virtual steel-out environment to the user. The locator 130 is used to obtain the position of the virtual reality glasses 120 and send it to the computer system 140. The computer system 140 is used to establish the aforementioned virtual tapping environment and receive user operation data of the operating mechanism 110 to control the virtual tapping environment accordingly. In addition, the computer system 140 can determine whether the tapping operation performed by the user is normal according to the aforementioned position of the glasses or the virtual tapping environment, and then output the training result to the user.

As shown in FIGS. 2 and 3, the carrying platform 200 includes arm columns 211 to 214 and a pedestal 250. The arm posts 211 to 214 are arranged on the pedestal 250, and the arm posts 211 to 214 have curved portions 211a to 214a, respectively. The aforementioned positioner 130 is arranged on the curved portions 211a and 213a of the arm posts 211 and 213, and defines a preset working area DA. In this embodiment, the chair 220 can be arranged in the preset work area DA to facilitate the user to sit on the chair 220 to perform tapping operations. The chair 220 has wheels 222 to facilitate the user to fine-tune its position. The aforementioned operating mechanism 110 includes a trolley operating mechanism 230 and a converter operating mechanism 240. The trolley operating mechanism 230 and the converter operating mechanism 240 are arranged on the pedestal 250 and adjacent to the preset work area DA to facilitate the user to operate the trolley operating mechanism 230 and the converter operating mechanism 240. For example, the trolley operating mechanism 230 has a trolley rocker 232 to facilitate the user to pull the trolley rocker 232 to control the speed of the trolley. For another example, the converter operating mechanism 240 has a converter rocker 242 to facilitate the user to pull the converter rocker 242 to control the tilting speed of the converter.

In one embodiment, a digital data capture card can be used to acquire/convert the output data of the trolley operating mechanism 230 and the converter operating mechanism 240. For example, according to the position of the trolley rocker 232, it is divided into three speeds (10 m/min, 20 m/min, and 30 m/min). For another example, according to the position of the converter rocker 242, the rotation speed (rpm) of the converter is obtained through a preset algorithm. In this way, the operating data provided by the operating mechanism 110 to the user of the computer system 140 includes the speed of the trolley and the rotational speed of the converter.

Please return to FIG. 3, the computer system 140 can be installed in the pedestal 250, and can be electrically connected to the operating mechanism 110, the virtual reality glasses 120, the locator 130 and other devices through a wired/infinite manner. In this embodiment, a computer screen 260 can be set on one of the arm posts 211 to 214 for senior personnel to control the computer system 140 to train the user. In addition, the pedestal 250 of this embodiment may be provided with wheels 270 to facilitate the movement of the carrying platform 200.

Please refer to FIGS. 4 and 5, which illustrate the virtual tapping environment displayed by the virtual reality glasses 120 according to an embodiment of the present invention. As shown in FIG. 4, the virtual tapping environment includes a converter 310, a laser light source 320, a trolley 330, a ladle 340, a baffle 350, and a leakage storage bucket 360. The molten steel ST is stored in the converter 310. When the user controls the converter 310 to tilt, the molten steel ST can be poured into the ladle 340 on the trolley 330 through the opening 312 of the converter 310. As shown in FIG. 5, when the converter 310 is tilted by the angle θ, the molten steel ST flows out from the opening 312. If the trolley 330 has reached the preset position at this time, the molten steel ST can flow into the ladle 340 normally. A plurality of floating balls 342 are provided in the ladle 340. When the molten steel ST flows into the ladle 340, the height of the molten steel ST can be obtained through the height of the float 342. In this embodiment, the median height of the float 342 is used as the liquid level height of the molten steel ST in the ladle 340, but the embodiment of the present invention is not limited to this.

Consider the abnormal conditions in the tapping operation. First, consider the abnormal situation in which molten steel ST overflows from the converter 310. If the user controls the pouring of the converter 310 too fast, the molten steel ST may overflow from the top of the converter 310. Therefore, the laser light source 320 is arranged on the top of the converter to emit a laser beam across the top of the converter. In this way, when the molten steel ST overflows from the top of the converter 310, the computer system 140 can know that the laser beam is interrupted, and determine that the user's tapping operation is abnormal.

Secondly, consider the abnormal condition that the molten steel ST is not poured into the ladle 340 correctly. If the user controls the converter 310 to dump to pour the molten steel ST, but the trolley 330 has not reached the preset position or has left the preset position, the molten steel ST will not be poured into the ladle 340 correctly, and will flow to the ladle 340. Outside the barrel 340. In order to detect this abnormal situation, a baffle 350 and a leakage storage bucket 360 are provided in this embodiment. The baffle 350 collects the molten steel ST that is incorrectly poured into the ladle 340, and makes it slowly flow into the leakage storage tank 360 along the baffle 350. A plurality of floating balls 362 are also arranged in the leakage storage bucket 360. When the molten steel ST flows into the leakage storage tank 360, the height of the molten steel ST can be obtained through the height of the float 362. In this embodiment, the median height of the float 362 is used as the liquid level height of the molten steel ST in the liquid leakage storage tank 360, but the embodiment of the present invention is not limited to this. When the liquid level of the molten steel ST in the leakage storage tank 360 is greater than a preset threshold, the computer system 140 determines that the user's tapping operation is abnormal.

Next, consider the abnormality in which the ladle 340 has a hole. If the ladle 340 has a hole, the molten steel ST flowing into the ladle 340 will flow out of the ladle 340 through the hole, for example, onto the trolley 330. In this embodiment, the attribute of the trolley 330 can be set as a penetrable object, so that when the molten steel ST flows out of the ladle 340 through the hole, it will fall to the baffle 350 and then flow to the leakage storage. Barrel 360. If the user continues to dump the converter 310 to pour the molten steel ST, the level of the molten steel ST in the liquid storage tank 360 will start to rise. When the liquid level of the liquid ST is greater than a preset threshold, the computer system 140 determines that the user's tapping operation is abnormal.

Furthermore, the virtual tapping environment of this embodiment may include indicator lights and buttons. When the indicator light is on, the computer system 140 can determine whether the user is expected to be in the direction of the indicator light according to the position of the virtual reality glasses 120 returned by the locator 130. If the user does not look in the direction of the indicator light, the computer system 140 determines that the user's tapping operation is abnormal. In addition, the virtual reality glasses 120 also capture the user's eyeball position to assist the judgment. In addition, the computer system 140 can use the finger gesture recognizer to recognize whether the user has pressed the correct button according to the instruction. If the user does not press the correct button, the computer system 140 determines that the user's tapping operation is abnormal.

It is worth mentioning that the baffle 350, the leakage storage tank 360, the floating ball 342, and the floating ball 360 of this embodiment can be set as transparent objects. In other words, users will not see these objects in the virtual tapping environment. In addition, considering that the user’s viewing angle is actually limited (limited by the size of the viewing window), the virtual reality glasses 120 can display the corresponding part of the virtual tapping environment according to the size of the actual viewing window, so as to show Steel work is more realistic.

Please refer to FIG. 6, which is a schematic flowchart of a method 600 for tapping work training according to an embodiment of the present invention. In the tapping operation training method 600, step 610 is first performed to use the computer system 140 to establish a virtual tapping environment. For example, senior staff can set a general steel tapping environment to train users in tapping operations. For another example, experienced personnel can set specific abnormal conditions (for example, the ladle 340 has a hole) to train the user in the tapping operation. Then, step 620 is performed to transmit the created virtual steel tapping environment to the virtual reality glasses 120, and the virtual reality glasses 120 are used to present the virtual steel tapping environment to the user. Then, step 630 is performed to provide the aforementioned operating mechanism 110 for the user to operate to obtain user operating data, such as the speed of the trolley and the rotation speed of the converter. Then, step 640 is performed to control the virtual tapping environment according to the user operation data. For example, the dumping of the converter 310/the movement of the trolley 330 is controlled. Then, step 650 is performed to determine whether the tapping operation performed by the user is normal according to the position of the virtual reality glasses 120 or the virtual tapping environment, and then output the training result. In one embodiment, the computer system 140 can use the finger gesture recognizer to determine whether the user's tapping operation is normal, and then output the training result.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the relevant technical field can make some changes and modifications without departing from the spirit and scope of the present invention.
