Description

Technical Field

[0001] The present invention belongs to the field of cloth trolleys, and particularly relates to a method for detecting the material level of a ring-shaped cloth trolley. Background Art

[0002] In the smelting process of submerged arc furnaces, various ore materials required for smelting are transported into the electric furnace through each bunker at the furnace top. Ensuring that there is always a certain amount of ore in the bunker is a major part of the safe production of submerged arc furnace smelting. In traditional submerged arc furnace smelting production, the vast majority rely on manual observation of the material level in each bunker to determine whether the bunker needs to be refilled. The refilling is carried out manually or by mechanical equipment. Currently, a fully automated cloth feeding and refilling system has not been formed, resulting in low efficiency and low precision in the cloth feeding process. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for detecting the material level of a ring-shaped cloth trolley to solve the problems existing in the prior art. To achieve the above object, the technical solution adopted by the present invention is as follows:

[0004] First step, install a high-speed ranging sensor at the bottom of the ring-shaped cloth trolley;

[0005] Second step, assume that the perimeter of the ring path is S1, the real-time position of the trolley on the ring track is S0, and there are N material level detection points on the ring path, and the central points of their positions are S01, S02, S03... S0N respectively;

[0006] Third step, assume that the trolley runs towards S0N among them, and it will pass through S01 on the path. When the position of the trolley |S0 - S01| < S2, put the distance data of the ranging sensor into the material level buffer of S01, where S2 is the detection range and is adjusted appropriately according to the running speed of the trolley and the size of the detection area;

[0007] Fourth step, during the feeding process of the trolley to each material pipe, it will automatically perform a material level scanning detection on the passing material level detection points;

[0008] Fifth step, add a validity period data to the material level value of each material pipe, and refresh this validity period just after the trolley finishes scanning. After the validity period expires, it is necessary to actively prompt to perform an active scan on the expired material level points to ensure the timely update of the material level;

[0009] Sixth step, when the trolley feeds a certain material level detection point, record the difference in the increase of the material level before and after feeding, and cumulatively record the total feeding height L1. Multiply the cumulative height value L1 by the cylinder area and then by the raw material density to obtain the cumulative feeding amount at each feeding point, realizing the cumulative recording of the feeding amount.

[0010] The present invention has the following beneficial effects:

[0011] This method detects the material level of multiple specific areas on the path by installing a high-speed distance measuring sensor at the bottom of the material distribution trolley moving along the circular path. When the trolley passes through these designated areas, the data collected by the distance measuring sensor is recorded and stored in association with the material level data of the corresponding area, so that the material level of each point on the circular path can be monitored separately. This method can not only accurately detect the material level of multiple points under the circular material distribution trolley, but also significantly reduce the number of sensors required. This improvement improves the reliability of the equipment, reduces the occurrence of failures, simplifies maintenance work, and saves construction and maintenance costs for the factory. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0013] The following will be combined with the attached embodiment of the present invention Figure 1 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0014] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0015] The first step is to install a high-speed distance sensor at the bottom of the circular fabric trolley. As a high-precision measuring tool, the high-speed distance sensor can quickly and accurately obtain the distance information between objects. Its unique working principle enables it to work stably in complex environments and provide reliable data support for various intelligent devices.

[0016] In the second step, assume that the circumference of the circular path is S1, the real-time position of the vehicle on the circular track is S0, and there are N material level detection points on the circular path, and their position center points are S01, S02, S03...S0N respectively;

[0017] In the third step, assume the trolley runs towards S0N among them, and it will pass through S01 on the path. When the distance between the trolley position |S0 - S01| < S2, put the distance data of the ranging sensor into the level buffer of S01. S2 is the detection range, which is adjusted appropriately according to the running speed of the trolley and the size of the detection area. As the trolley runs, the system will continuously update the level buffer data at point S01 to ensure the real-time and continuity of the data. At the same time, the system will also dynamically adjust the detection range S2 according to the actual running speed of the trolley and the size of the detection area to adapt to different working environments and changing requirements.

[0018] This real-time data acquisition and processing method not only improves work efficiency but also greatly enhances the accuracy of work. Through continuous optimization and adjustment, the trolley can better complete the predetermined tasks and provide strong data support.

[0019] In the fourth step, during the feeding process of the trolley to each material pipe, it will automatically perform a level scan detection on the level detection points passed by; at the same time, it will also record various data during the feeding process, including feeding time, feeding amount, level change, etc., for subsequent data analysis and management.

[0020] In the fifth step, add a validity period data to the level value of each material pipe, and refresh this validity period just after the trolley finishes scanning. After the validity period expires, it is necessary to actively prompt to perform an active scan on the expired level points to ensure the timely update of the level.

[0021] In the sixth step, when the trolley feeds a certain level detection point, record the difference in the increase in the level before and after feeding, and cumulatively record the total feeding height L1. Multiply the cumulative height value L1 by the cylinder area and then by the raw material density to obtain the cumulative feeding amount at each feeding point, realizing the cumulative recording of the feeding amount.

[0022] This method realizes the detection of the levels of multiple specific areas on the path by installing a high-speed ranging sensor at the bottom of the cloth trolley moving along the circular path. When the trolley passes through these designated areas, the data collected by the ranging sensor is recorded and associated with the level data of the corresponding areas, so that the levels of each point on the circular path can be monitored separately. By using this method, not only can the multi-point levels under the circular cloth trolley be accurately detected, but also the number of required sensors can be significantly reduced. This improvement enhances the reliability of the equipment, reduces the failure rate, simplifies the maintenance work, and saves the construction and maintenance costs for the factory.

[0023] The embodiments described above are only descriptions of the preferred modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
