<Table 1> Role of body part S1 and laser sensor part S3

Table 1 shows the configuration and role of the body portion (S1) and the laser sensor portion (S3) of the stacker and reclaimer (10), as described above the rough 14 of the body portion (S1) is the image of the boom (11). The lower working angle performs a function of vertically adjusting the angle of 78 ° to 110 ° based on the vertical line of the body part S1, and the slew 15 is a starting point in the direction of the front part of the boom forming part S2. By performing a function that can be rotated horizontally from 230 ° to 270 ° horizontally, the treble 16 performs the function of moving the stacker and recramer 10 forward and backward along the hypothesized rail,
When the rough 14 is moved up and down, the height detecting laser sensor 17a is provided at both sides of the bucket 12 to sense the height of the load to accurately recognize the angle of the rough 14, and the slew 15 is left and right. The end position detection laser sensor 17b provided at the front end of the boom 11 detects the left and right widths of the load during the rotation operation so that the angles of the left and right widths of the boom 11 can be accurately recognized. Accordingly, when moving forward and backward, the shape detecting laser sensor 17c provided at the front end of the boom 11 accurately recognizes the length of the width between the front and the rear of the load, and the angle of the load height and the left and right width angles. Recognize the length of the width between, and the front and the back, respectively.
The angle of the rough 14, the angle of the slew 15, the travel distance of the treble 16, etc. change according to the shape of the load that changes as the stacker and reclaimer 10 is carried. After collecting and storing the fluctuation value in real time in the mobile device PLC unit 20, the server PC unit 22 receives the initial value and the fluctuation value of the loaded file, and primarily the initial of the rough 14 and the slew 15. The 2D yard map data is generated using the value and the real-time change value, and the length of the width between the front and the back by the travel 16 is applied to the 2D data and monitored as the 3D yard map data.
The workload control detection laser sensor 17d stops the loading operation when the appropriate amount of raw material is loaded in the raw material yard based on the length of the boom 11 and the moving distance of the treble 16. It detects work start and end points.
In the same manner as described above, the 2D data and the 3D data are generated and monitored in real time while the stacking mode is loaded in the reverse mode as well as the stacking mode.

As described above, the current ampere (A) for the existing ampere (A) according to the load change of the drive motor 41 responsible for driving the conveyor belt 40 for loading and transporting minerals on the conveyor belt 40 A current-to-current weighing program 30, which is a method for measuring the weight per unit distance of the load to be transported by reading the change value, is shown in the algorithm flow chart in FIG. Is stored in the HMI PC unit 23 and inputs and executes the amount of change in amperes A of the drive motor 41 inputted from the mobile device PLC unit 20 via the server PC unit 22 to execute the raw material compared to the current. This is a device system that automatically displays the real-time transport weight of the bullet.When the real-time motor amp (A) flows to the normal value in the MAX state, it is necessary to first determine whether the bullet is loaded and then When the motor driven at 60 amps (A) loads the load, the 70 amps (A) is measured. The weight of the transfer load of the belt scale 13 of the motor driven at a speed of 180 m per minute is measured. In the above three minutes, the transfer distance of 540m is derived, and if the current weight inputted per one ampere was 100 tons (t), the ampere change amount was 10 amperes per 54m, so 1000 tons (T) was derived and 1000 tons ( t) × 10 = 10000 tons (t) of load is measured, and if you look at the procedure of weighing algorithm compared to the current, the current of the motor is received and stored, and the current AVG (average value) and the current standard procedure are stored. If it is included in the allowable range of the mean error in the step 30 of determining the average error allowable range, it is necessary to modify the allowable range and the standard deviation table without modifying the current allowable range. If the weight table is modified in the weight table modification step 32 by applying the current, the weight table is terminated by modifying the weight table and applying the weight according to the current. If the average error is not included in the above range, the current is allowed. If it is determined that the current tolerance is to be corrected in the current allowance correction step 31 by modifying the current range, it is excluded from the hunting range and when not modified, compared with the hunting table and stored as a hunting value or discarded as garbage value. When the table value of the weight table is not corrected, the current is compared with the weight. When the weight allowable range is corrected in the weight allowable range correction step 33, the table is searched for the appropriate weight and compared with the appropriate weight. Determination of application and hunting if the weight tolerance is not modified Compared to the motor current of the conveyor belt 40 of measuring the weight of the load transported on the conveyor belt 40 according to the amperage (A) change amount of the drive motor 41 in a manner of storing or discarding the cable. It relates to a weighing system.
