Description

Technical Field

[0001] The present invention relates to the technical field of intelligent material management, and in particular to a silo loading method, system and mixing station. Background Art

[0002] During the material loading process at existing mixing stations, the identified license plate information is typically matched against the material procurement plan to obtain the currently delivered material information. The material inventory management table is then queried based on the purchased material information to determine the corresponding storage location information, thereby matching the optimal loading location. However, this approach fails to account for the possibility of simultaneous delivery of the same type of material, which can lead to system inventory misjudgments, incorrect loading bin assignments, and low efficiency. Therefore, designing a more accurate and effective silo loading solution to improve the efficiency of loading bin assignments has become a pressing technical issue. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following is a detailed description of an embodiment of the silo loading method according to the present invention. Figure 1 As shown, it is a flow chart of the silo loading method provided by an embodiment of the present invention, and the specific implementation process includes the following steps:

[0035] Step 101: After determining the candidate loading bin corresponding to the material loaded by the current train, determine whether there is a first round of loading in the candidate loading bin.

[0036] In practice, due to the limited number of suppliers' vehicles, in most cases the same loading vehicle is required to transport multiple materials. Existing technologies are usually unable to distinguish situations in which the same vehicle is required to transport multiple types of materials in a material procurement plan, resulting in incorrect loading bin determination. The present invention obtains input vehicle and material information by scanning a QR code on a mobile terminal, and directly establishes a corresponding relationship between the vehicle information pre-submitted and stored in the ERP (Enterprise Resource Planning) system and the material information. This solves the problem in the existing technology of associating the identified license plate information with the material procurement plan, but being unable to uniquely determine the material type transported by the loading vehicle based on the plan, resulting in incorrect loading bin assignment.

[0037] Specifically, that is, before determining the alternative loading bin corresponding to the material loaded by the current vehicle, it also includes: obtaining the license plate information corresponding to the loading vehicle and the material information loaded by the delivery party by scanning the code to the mobile terminal before the vehicle enters the site, and determining the corresponding relationship between the license plate information and the material information; when the vehicle enters the site, according to the license plate information of the current vehicle identified by the weighing system and the corresponding relationship, determine the material to be loaded associated with the license plate information of the current vehicle, and then determine the alternative loading bin corresponding to the material loaded by the current vehicle. In the actual implementation process, the present invention can also update the corresponding relationship between the license plate information and the material information, or clear the original corresponding relationship between the license plate information and the material information after each loading is completed and exits the site, and re-establish the corresponding relationship when the loading vehicle comes next time, and re-establish a new corresponding relationship before the next entry to load. Among them, the embodiment of the present invention includes but is not limited to the use of the license plate information, and can also be other identity identification information that can identify the current vehicle, such as frame number, electronic tag, etc. The loading vehicle can refer to a vehicle that transports various types of mixing station silo materials. The mobile terminal can refer to a network device such as a smartphone, tablet, or portable barcode scanning device. The material information includes, but is not limited to, the type of material being loaded by the current vehicle, such as concrete, lime powder, and cement. By identifying the vehicle's license plate upon entry, the weighing system can read the material information associated with that license plate. This information is then automatically matched to the loading silo's inventory data recorded in the ERP system, displayed simultaneously on the mobile terminal and external display, and the corresponding loading silo number is provided via voice prompt.

[0038] In this step, after determining the alternative loading bin corresponding to the material loaded by the current vehicle, it is also necessary to determine whether there is a first round of loading in the alternative loading bin (which may include one or more powder bins belonging to the first round of loading, or there may be no powder bin belonging to the first round of loading). It should be noted that the judgment period for the first round of loading is determined by the mixing station customer, which may be one month, one day or one year. The first round of loading means that within this judgment period, the current powder bin is the first time to be loaded. It should be noted that if the first round of loading is specifically defined, there is no need to perform subsequent loading completion judgment. For example, the first round of loading is defined as: no other vehicle is loading the current powder bin, and the loading is not completed, then it is the first round of loading.

[0039] Step 102: If it does not exist, then for the alternative loading bin that is not the first round of loading, determine whether the loading of the previous vehicle is completed. If it is completed, determine its actual material level data based on the material level data detected by the intelligent material level system. If it is not completed, determine its estimated material level data based on the estimated inventory data of the ERP system; based on the actual material level data and / or the estimated material level data, determine the lowest comparison material level data.

[0040] In this step, if there is no alternative loading bin (that is, all of them are not the first round of loading), then it is directly determined whether the loading of each alternative loading bin is completed. For the loading bin where the previous vehicle has completed loading, its actual material level data is determined based on the detection data of the intelligent material level system; for the unfinished loading bin, the estimated inventory data in the ERP system is used as its estimated material level data. If there is, then for the alternative loading bin for the first round of loading, its initial material level data is determined based on the material level data detected by the intelligent material level system, and then the lowest comparative material level data is determined based on the initial material level data, the actual material level data and / or the estimated material level data. Among them, the existence of the first round of loading may be that all of them are the first round of loading, or one or more of them are the first round of loading. If one or more of them are the first round of loading, it is necessary to determine the lowest comparative material level data in combination with the judgment of other alternative loading bins, that is, it is necessary to determine the lowest comparative material level data based on the initial material level data, the actual material level data and / or the estimated material level data.

[0041] It should be noted that the application scenario of using the ERP system for pre-estimation setting is that when the current vehicle is preparing to load materials, the vehicle in front is loading the same material and has not completed loading. At this time, the material level judgment based on the detection data of the intelligent material level system will be inaccurate, so it is necessary to obtain estimated inventory data through the ERP system. For example, a certain loading bin is in the process of loading materials. Although the existing inventory in the loading bin is the lowest material level data, there are still some materials in the current loading vehicle that are in the process of loading or waiting to be transported to the loading bin. As a result, the lowest material level data of the loading bin at this time is actually an inventory judgment error, which can easily lead to the problem of incorrect assignment of loading bins for subsequent incoming vehicles. Therefore, during the loading process, the present invention also needs to make an advance estimate of the material inventory and store it in the ERP system, so that the lowest material level data of each bin of the same material can be determined when the next round of vehicles enter the site for loading, thereby assigning the best loading bin. If a high material level alarm occurs during the loading process, the gas supply is stopped to prevent explosion, and a buzzer alarm is used to prompt. The silo is a powder silo or powder tank.

[0042] Specifically, that is, before determining the estimated material level data based on the estimated inventory data of the ERP system, it is necessary to use the ERP system to make an estimate in advance for the situation where the previous vehicle loading corresponding to the alternative loading bin that is not the first round of loading is not completed, and obtain the estimated inventory data of the alternative loading bin that is not the first round of loading after the previous vehicle loading is completed. For example, the current loading vehicle A is entering the site to prepare to load material A, where the loading bins corresponding to material A are 1# bin, 3# bin and 4# bin. At this time, the actual material level in 1# bin is the lowest, but vehicle B is already loading material to 1# bin and after vehicle B finishes loading material, the lowest material level in 1#, 3# and 4# bins is no longer 1# bin (similarly, there may be multiple vehicles loading material to other bins). Therefore, the logic of assigning a bin to A bin should be based on the comparison of the estimated inventory data after all unfinished loading actions are completed. Therefore, for the situation where the preceding vehicle's loading is not completed for the alternative loading bin that is not the first round of loading, the present invention uses the ERP system to make an estimate, obtain the estimated inventory data of the alternative loading bin that is not the first round of loading after the preceding vehicle's loading is completed, and then accurately assign the bin position of the loading bin.

[0043] Step 103: Determine a target loading bin based on the lowest comparison material level data.

[0044] In an embodiment of the present invention, the alternative loading bin corresponding to the lowest comparative material level data can be directly determined as the target loading bin. In addition, as a preferred embodiment, in the actual implementation process, since there is a situation where the material loaded on the loading vehicle is more than the remaining space of the target loading bin, it is necessary to further instruct the loading vehicle to enter the site again for a second weighing to achieve the loading of all the remaining materials. Therefore, it is necessary to further determine whether the current train needs to be loaded twice based on the estimated net weight of the materials of the current train in the ERP system and the lowest comparative material level data. If so, an indication information is generated that the current train needs to enter the site for a second time for loading; after the current train enters the site for the second time, the target loading bin is re-determined to determine the target loading bin corresponding to the second loading. Specifically, it is first necessary to determine whether the estimated net weight of the materials of the current train in the ERP system is greater than the remaining space of the target loading bin corresponding to the lowest comparative material level data. If so, it is determined that the current train needs to be loaded twice.

[0045] That is, after the initial target loading bin is determined based on the lowest comparison material level data and the estimated net weight of the material, even if the target loading bin is judged to be the lowest material level, it is necessary to further judge whether the estimated net weight of the material of the current vehicle is greater than its remaining space. If it is judged to be greater than the remaining space, the estimated inventory data in its ERP system will be assigned as full warehouse (as the basis for judging the next loading vehicle), and the loading vehicle of the current vehicle will be prompted to be weighed a second time after leaving the site.

[0046] Furthermore, after determining the target loading bin based on the minimum comparison material level data, it also includes: when the current train arrives at the loading bin, judging whether the current loading bin is the target loading bin, and if so, returning a prompt message to the current train that the current loading bin is the target loading bin; if not, returning a prompt message to the current train that the current loading bin is wrong.

[0047] At the same time, after returning the prompt information that the current loading bin is the target loading bin to the current train, it also includes: detecting the real-time material level height inside the current loading bin based on a preset material level meter, and when the real-time material level height reaches or exceeds the preset material level height threshold, prompting to stop transporting materials to the current loading bin.

[0048] Furthermore, after determining the target loading bin based on the minimum comparison material level data, the system further includes: obtaining inventory record data and purchase, sales, and inventory statistics from the ERP system upon completion of a loading task in a loading cycle; calibrating the material level data detected by the intelligent material level system at preset time intervals based on the inventory record data and the purchase, sales, and inventory statistics to correct for detection deviations of the intelligent material level system. The purchase, sales, and inventory statistics refer to the incoming materials, used materials, and the remaining materials after the incoming materials have been deducted from the used materials, recorded in each loading bin over a period of time.

[0049] Among them, the intelligent material level system refers to an initial detection system in the prior art that can measure the estimated material level data of each bin by obtaining the stress from the bottom support feet of the upper bin at the upper bin, and will not be described in detail here.

[0050] like Figure 2As shown, in a specific embodiment, before each vehicle enters the site, the vehicle information and material information (i.e., powder material information) filled in by the delivery party is obtained through the mobile terminal application, and the current vehicle weighing plan is submitted and stored in the ERP system to avoid the error of the license plate and material information association when the same loading vehicle transports different materials for weighing. When the vehicle enters the site, the intelligent weighing system reads the material information corresponding to the license plate information, automatically calculates the net weight information of the material in the current loading vehicle, and obtains the lowest comparative material level data of each loading bin of the same material in the station through the detection data of the intelligent material level system and the estimated inventory data obtained by the ERP system. Then, the loading bin is automatically matched, and the information of the loading bin is displayed on the outdoor display screen, the self-service ticket machine, and the voice prompt of the loading bin on the mobile terminal application. During the loading bin assignment process, when estimating the net weight of the loading material, the gross weight information can be obtained by weighing. The tare weight information calculation can be achieved by tare weight import (such as obtaining the vehicle's historical tare weight), vehicle tare weight estimation (such as the first entry, estimating the tare weight based on the vehicle equipment quality information entered by the delivery party) or manual entry of tare weight data. The calculated net weight information of the material is stored in the ERP system as the estimated net weight. Specifically, the real-time material level can be measured through the intelligent material level system (for example, when the first vehicle enters the site for the first time, the powder tank inventory data takes the intelligent material level data), or through the estimated inventory data of the ERP system (for example, if the previous vehicle has not completed loading, the subsequent inventory of the same type of material will be calculated based on the estimated inventory data of the ERP system). When assigning the loading bin, the first vehicle to load the material determines the bin based on the real-time minimum material level and estimated net weight of the powder tank intelligent material level system; if the previous vehicle has not completed loading, the subsequent inventory of the same type of material will be assigned based on the ERP estimated minimum inventory and the estimated net quantity of the current loading vehicle. Furthermore, after the vehicle arrives at the designated bin, the delivery party scans the powder tank information code; when the loading bin indicated by the information code is consistent with the target loading bin assigned by the intelligent weighing system, the powder tank is allowed to feed, otherwise the mobile application prompts that the loading bin is wrong, so that the delivery party needs to confirm the loading bin and try again. During the loading process, material inventory is estimated and stored in the ERP system as estimated inventory data, facilitating the next loading vehicle's entry. If a high material level is detected, an alarm is triggered, halting gas flow to prevent explosions. After loading is complete, the vehicle is weighed again to obtain an accurate tare weight. The system automatically calculates the net weight of the material, which is then stored in the ERP system for management review and inventory accumulation. The delivery party can then self-invoice and leave the site.

[0051] like Figure 3As shown, the powder material intelligent management system of the present invention can be divided into a powder tank (i.e., feeding silo) inventory acquisition system, an intelligent weighing system, and a powder tank control system. Ethernet communication is used for data exchange between these systems. The powder tank inventory acquisition system can include an ERP system for acquiring system recorded data to obtain estimated inventory data, an intelligent material level system for obtaining real-time monitoring data, and a financial data system for obtaining statistical data.

[0052] The silo loading method described in the embodiment of the present invention determines whether there is a first-round loading situation in the alternative loading silo after determining the alternative loading silo corresponding to the material loaded by the current vehicle. For the alternative loading silo that is not the first-round loading, it determines whether the previous vehicle loading is completed. If it is completed, its actual material level data is determined based on the material level data detected by the intelligent material level system. If it is not completed, its estimated material level data is determined based on the estimated inventory data of the ERP system; then, based on the actual material level data and / or the estimated material level data, the lowest comparative material level data is determined; finally, the target loading silo is determined based on the lowest comparative material level data. It takes into account the actual usage scenarios more comprehensively and has stronger applicability. It can improve the assignment accuracy of the loading silo and effectively improve the efficiency of silo loading.

[0053] Corresponding to the above-mentioned silo loading method, the present invention also provides a silo loading system.

Please refer to Figure 4 As shown, it is a structural schematic diagram of a silo loading system provided by an embodiment of the present invention.

[0054] The silo loading system of the present invention specifically includes:

[0056] The lowest comparative material level data determining unit 402 is configured to determine whether the preceding vehicle has completed loading of the alternative loading bin that is not the first loading bin, if the preceding vehicle has completed loading of the alternative loading bin, and if so, to determine the actual material level data based on the material level data detected by the intelligent material level system; if not, to determine the estimated material level data based on the estimated inventory data of the ERP system; and to determine the lowest comparative material level data based on the actual material level data and / or the estimated material level data;

[0057] The target loading bin determining unit 403 is configured to determine the target loading bin based on the lowest comparison material level data.

[0058] Furthermore, before determining the alternative loading bin corresponding to the material loaded by the current train, it also includes: a current train material identification unit, which is used to pre-acquire the license plate information corresponding to the loading vehicle and the material information loaded this time before the vehicle enters the site, and determine the correspondence between the license plate information and the material information; when the vehicle enters the site, the material to be loaded associated with the license plate information of the current train is determined based on the identified license plate information of the current train and the correspondence.

[0059] Furthermore, the target loading bin determination unit is specifically used to: determine whether the current train needs secondary loading based on the estimated net weight of the materials of the current train in the ERP system and the minimum comparison material level data; if so, generate indication information that the current train needs to enter the site for secondary loading; after the current train enters the site for the second time, re-determine the target loading bin to determine the target loading bin corresponding to the secondary loading.

[0060] Furthermore, the target loading bin determination unit is specifically used to determine whether the estimated net weight of the material of the current train in the ERP system is greater than the remaining space of the target loading bin corresponding to the lowest comparison material level data. If so, it is determined that the current train needs secondary loading.

[0061] Furthermore, before determining the estimated material level data based on the estimated inventory data of the ERP system, it also includes: an estimated inventory data acquisition unit, which is used to use the ERP system to make an estimate for the situation where the loading of the previous vehicle corresponding to the alternative loading bin that is not the first round of loading is not completed, and obtain the estimated inventory data of the alternative loading bin that is not the first round of loading after the loading of the previous vehicle is completed.

[0062] Furthermore, the minimum comparison material level data determination unit is also used to: if any, determine the initial material level data of the alternative loading bin for the first round of loading based on the material level data detected by the intelligent material level system; and determine the minimum comparison material level data based on the initial material level data, the actual material level data and / or the estimated material level data.

[0063] Furthermore, after determining the target loading bin based on the minimum comparison material level data, it also includes: an intelligent material level system deviation calibration unit, which is used to obtain the inventory record data and purchase, sales and inventory statistics of the ERP system after completing the loading task in a loading cycle; based on the inventory record data and the purchase, sales and inventory statistics, the material level data detected by the intelligent material level system is calibrated to correct the detection deviation of the intelligent material level system.

[0064] Furthermore, after determining the target loading bin based on the minimum comparison material level data, it also includes: a target loading bin determination unit, which is used to determine whether the current loading bin is the target loading bin when the current train arrives at the loading bin. If so, a prompt message indicating that the current loading bin is the target loading bin is returned to the current train; if not, a prompt message indicating that the current loading bin is wrong is returned to the current train.

[0065] Furthermore, after returning the prompt information that the current loading bin is the target loading bin to the current train, it also includes: a material level height unit, which is used to detect the real-time material level height inside the current loading bin based on a preset material level meter. When the real-time material level height reaches or exceeds the preset material level height threshold, it prompts to stop transporting materials to the current loading bin.

[0066] The silo loading system described in the embodiment of the present invention determines whether there is a first-round loading situation in the alternative loading silo after determining the alternative loading silo corresponding to the material loaded by the current vehicle. For the alternative loading silo that is not the first-round loading, it determines whether the loading of the previous vehicle is completed.
