[0002] The aggregate of the concrete station is generally stored in an open or non-open yard, mainly including gravel and yellow sand and other concrete raw materials. The wall is used to separate the stacking area.

[0056] Figure 2 The flow chart of the method of stockyard storage and transportation warehouse according to the embodiments of the present application is schematically shown. As shown in Figure 2 The embodiments of the present application provide a method of stockyard storage and transportation warehouse, and the control method is mainly applied to the controller 101 in the above Figure 1 The method can include the following steps:
[0057] Step 201, receiving the three-dimensional data of the stockpile before and after loading sent by the measuring device respectively;
[0058] Step 202, determining the initial material volume according to the three-dimensional data of the stockpile before loading;
[0059] Step 203, determining the target material volume according to the three-dimensional data of the material pile after loading;
[0060] Step 204, determining the volume difference as the difference between the target material volume and the initial material volume;
[0061] Step 205, respectively acquiring the weight of the material pile before loading and after loading;
[0062] Step 206, determining the weight difference according to the weight of the material pile before loading and after loading;
[0063] Step 207, determining the volume-weight ratio according to the volume difference and the weight difference;
[0064] Step 208, determining the target material weight as the product of the volume-weight ratio and the target material volume.
[0065] In the embodiments of the present application, the measuring device refers to a device used to acquire the three-dimensional data of the material pile. The measuring device can include but is not limited to a spreader, a radar, and a laser sensor, etc. The three-dimensional data refers to the data of the material pile in three dimensions, which can include the width, length, and height of the material pile. The initial material volume refers to the volume of the material pile before loading. The target material volume refers to the volume of the material pile after loading, and also refers to the volume of the material to be obtained by inventory. The volume-weight ratio refers to the weight of the object per unit volume. By calculating the volume-weight ratio, the weight of the material pile can be determined. The target material weight can refer to the weight of the material to be obtained by inventory.
[0066] The measuring device communicates with the controller. The measuring device first acquires the three-dimensional data of the material pile, i.e., the length, width, and height data of the material pile. Then the three-dimensional data of the material pile is sent to the controller. The controller respectively receives the three-dimensional data of the material pile before loading and after loading sent by the measuring device. And respectively determines the initial material volume and the target material volume according to the three-dimensional data before loading and after loading. That is, the initial material volume is determined according to the three-dimensional data before loading, and the target material volume is determined according to the three-dimensional data after loading. When determining the material volume according to the three-dimensional data, point cloud algorithm or other methods can be used. When the measuring device acquires the three-dimensional data, the radar and the laser sensor need to work together. The radar is used to acquire the two-dimensional coordinate set of the material pile in the width and depth directions, and the laser sensor is used to acquire the one-dimensional coordinate set of the material pile in the length direction. The one-dimensional coordinate set and the two-dimensional coordinate set are combined to obtain the three-dimensional data of the material pile. By determining the material volume according to the three-dimensional data acquired by the measuring device, the manual operation can be reduced, and the measurement accuracy can be improved.
[0067] After obtaining the initial and target material volumes, the controller subtracts the target and initial material volumes to obtain the volume difference. The controller also acquires the weight of the material pile before and after loading, and subtracts this weight from the initial weight to obtain the weight difference. This allows the determination of the volume and weight differences that satisfy the same conditions. These volume and weight differences can then be used to determine the bulk density ratio.
[0068] After obtaining the volume and weight differences of the material piles, the bulk density ratio is determined based on these differences. The bulk density ratio satisfies the formula ρ = ΔM / ΔV, where ρ is the bulk density ratio, ΔM is the weight difference, and ΔV is the volume difference. By determining the bulk density ratio, the weight of different batches of material piles with different volumes can be determined. For example, during a feeding process, after determining the target material volume based on three-dimensional data, the target material volume is multiplied by the bulk density ratio to determine the target material weight. Before feeding, the batch of material can be weighed to determine the actual weighed weight, thereby judging whether there is an error between the target material weight determined by the bulk density ratio and the actual weighed weight. If an error exists, the bulk density ratio needs to be corrected. Determining the target material weight based on the bulk density ratio is more accurate than the existing method of multiplying volume by average density.
[0069] The above technical solution involves receiving three-dimensional data of the material pile before and after loading from a measuring device; determining the initial material volume based on the three-dimensional data before loading; determining the target material volume based on the three-dimensional data after loading; defining the volume difference between the target material volume and the initial material volume; acquiring the weight of the material pile before and after loading; determining the weight difference based on the weight of the material pile before and after loading; determining the bulk density ratio based on the volume difference and weight difference; and finally, determining the target material weight by multiplying the bulk density ratio and the target material volume. By performing three-dimensional measurement of the material pile to obtain its volume and then determining its weight based on the bulk density ratio, manual operation is reduced, improving the accuracy and efficiency of inventory management.
[0070] In this embodiment of the application, the bulk density ratio satisfies formula (1):
[0071] ρ=△M / △V;(1)
[0072] Where ρ is the bulk density ratio, ΔM is the weight difference, and ΔV is the volume difference.
[0073] Specifically, the bulk density ratio satisfies the formula ρ=△M / △V. Wherein, ρ is the bulk density ratio, △M is the weight difference, and △V is the volume difference. The weight difference is obtained by subtracting the weight before the material is loaded from the weight after the material is loaded. When determining the volume difference, the three-dimensional data of the material pile before loading and the three-dimensional data of the material pile after loading can be obtained by the measuring device, and the initial material volume and the target material volume are determined according to the three-dimensional data before loading and the three-dimensional data after loading respectively, and then the target material volume and the initial material volume are subtracted to obtain the volume difference. By determining the bulk density ratio, the weight of the material pile of different batches and different volumes can be determined.
[0074] In the embodiment of the present application, the measuring device includes a radar and a laser sensor, and the three-dimensional data of the material pile before loading and the three-dimensional data of the material pile after loading sent by the measuring device are respectively received, including:
[0075] The first direction and the second direction of the two-dimensional coordinate set of the material pile sent by the radar before and after the material pile is loaded, and the one-dimensional coordinate set of the third direction of the material pile sent by the laser sensor are received;
[0076] The two-dimensional coordinate set and the one-dimensional coordinate set are combined to obtain the three-dimensional data of the material pile before and after loading;
[0077] Wherein, the first direction is the direction of the width of the material pile, the second direction is the direction of the depth of the material pile, and the third direction is the direction of the length of the material pile.
[0078] Specifically, the measuring device can include a radar and a laser sensor. The radar is used to measure a two-dimensional coordinate set of the stockpile in a first direction and a second direction, and the laser sensor is used to measure a one-dimensional coordinate set of the stockpile in a third direction. The first direction refers to a direction along the width of the stockpile, the second direction refers to a direction along the depth of the stockpile, i.e., the height of the stockpile, and the third direction refers to a direction along the length of the stockpile. The radar can determine the distance of the radar to the stockpile by sending a signal, i.e., the distance along the width direction of the stockpile. Meanwhile, because the material car is suspended above the stockpile, the depth of the stockpile, i.e., the distance along the depth direction of the stockpile, can be determined by sending a signal downward. The laser sensor is arranged on the material car and moves together with the material car. After moving, the laser sensor can determine the distance of the laser sensor to the origin, i.e., the distance along the length direction of the stockpile, by emitting laser. The origin is the starting point of the movement of the material car. The radar can include a millimeter wave radar and a laser radar. The millimeter wave radar has the characteristic of fast real-time and can be used to measure the height of the stockpile. The laser radar can be used to measure the width of the stockpile. The controller can receive the two-dimensional coordinate set along the width direction and the depth direction of the stockpile before and after the stockpile is loaded, and the one-dimensional coordinate set along the length direction, and then combine the two-dimensional coordinate set and the one-dimensional coordinate set to obtain the three-dimensional data of the stockpile before and after the stockpile is loaded, respectively. By using the radar and the laser sensor to jointly measure, automatic measurement of the data of the stockpile in three directions can be realized, manual operation is reduced, and the measurement accuracy is improved.
[0079] In the embodiment of the present application, the measuring device further includes a material car, the laser sensor is arranged on the material car, and the one-dimensional coordinate set of the third direction of the stockpile received by the laser sensor includes:
[0080] The material car is controlled to move;
[0081] The one-dimensional coordinate of the stockpile collected by the laser sensor is received at a preset period to obtain the one-dimensional coordinate set.
[0082] Specifically, the measuring device can further include a material car, which refers to a device composed of a frame, a hopper, a vibrator, a shock-absorbing spring, a walking mechanism, a buckle mold bucket lifting mechanism, and an electrical system, and is used for unloading. The laser sensor and the radar are both arranged on the material car and are fixed according to the relative position. When the controller issues a control instruction, the controller controls the material car to move, and the laser sensor also moves with the material car. Taking the starting position of the material car as the origin, the laser sensor can measure the distance of the position of the material car after moving to the origin, i.e., the one-dimensional coordinate along the third direction. By moving the material car and the laser sensor together, data collection along the length direction of the stockpile can be realized.
[0083] In the embodiment of the present application, the method can further include:
[0084] In the case of receiving the mapping instruction, the controller controls the spreader to run according to the preset track;
[0085] In the process of running according to the preset track, the radar and the laser sensor collect the three-dimensional data of the stockyard;
[0086] According to the three-dimensional data of the stockyard, mapping is performed to obtain the point cloud map of the stockyard.
[0087] Specifically, the point cloud map refers to a data matrix composed of point cloud information. In the process of data collection by the measuring device, the stockyard environment can be mapped to obtain the stockyard material condition. When receiving the start real-time mapping instruction, the spreader can be controlled to run according to the preset track. The preset track refers to the preset running track of the spreader. For example, the preset track can be running along the stockyard for one round. And in the process of running of the spreader, the radar and the laser sensor collect the three-dimensional data of the stockyard in real time, collect the data of each point of the stockyard, and finally record the data in the form of a point cloud map to obtain the point cloud map of the stockyard. Through real-time mapping of the stockyard, the current stockyard condition information can be obtained in real time.
[0088] In the embodiment of the application, the method can further include:
[0089] In the case of receiving the stop instruction, the spreader is controlled to stop running.
[0090] Specifically, when the spreader completes running according to the preset track and returns to the original point, that is, the spreader has completed running for one round. The controller issues a stop instruction to control the spreader to stop running. At this time, the data collection of the measuring device on the stockpile has been completed. The spreader can stop moving.
[0091] Through the above technical solution, the three-dimensional data of the stockpile before and after loading is respectively received by the measuring device; the initial material volume is determined according to the three-dimensional data of the stockpile before loading; the target material volume is determined according to the three-dimensional data of the stockpile after loading; the difference between the target material volume and the initial material volume is determined as the volume difference; the weight of the stockpile before and after loading is respectively obtained; the weight difference is determined according to the weight of the stockpile before and after loading; the bulk density ratio is determined according to the volume difference and the weight difference; and finally the product of the bulk density ratio and the target material volume is determined as the determined target material weight. Through three-dimensional measurement of the stockpile to obtain the volume, and then determining the weight according to the bulk density ratio, manual operation is reduced, and the accuracy and efficiency of the inventory are improved.
[0092] Figure 3 A flowchart of a method of a stockyard storage and transportation warehouse according to an embodiment of the application is schematically shown. As shown in Figure 3 The embodiment of the application provides a method of a stockyard storage and transportation warehouse, which can include the following steps:
[0093] S1, map system operation task;
[0094] S2, scanning type parameter determination;
[0095] S3, equipment state inspection;
[0096] S4, determine whether to build a map, if yes, enter S5, if no, return to S3;
[0097] S5, start positioning communication;
[0098] S6, ready data acquisition;
[0099] S7, single-point laser ranging calculation;
[0100] S8, material car body positioning;
[0101] S9, data acquisition;
[0102] S10, map update;
[0103] S11, map data calculation processing, return to S1;
[0104] S12, determine whether a stop instruction is received, if yes, enter S13, if no, return to S9;
[0105] S13, data acquisition is completed.
[0106] Specifically, first, the operation task of the map system is determined by the management system, and then the parameters of the scanning type are determined, and then the equipment state is checked. In the case of normal equipment state, it is judged whether to start real-time mapping. Mapping the stockyard requires constructing according to the collected data during data collection, therefore, it is necessary to judge whether real-time mapping has been started, and then control the spreader to start moving when real-time mapping has been started. In the case of not starting real-time mapping, the equipment state is continuously checked. In the case of starting real-time mapping, the positioning communication module is started, and the data collection is ready. At the same time, the spreader body is positioned by single-point laser ranging calculation. By starting the positioning communication module, real-time positioning of the spreader can be realized, and the distance from the spreader to the origin can be obtained by single-point laser ranging. The origin refers to the starting position of the spreader movement. When all the preparations are completed, data collection is started. During data collection, the map is updated in real time. Because after collecting the stockyard data, when the stockyard information changes, the map of the stockyard will also be updated in real time. After processing the data, the map system operation task determination step is returned to determine whether the task needs to be changed according to the updated data and map. When a stop instruction is received, it means that the data collection has been completed. When no stop instruction is received, data collection continues. By constructing the map of the stockyard, the stockyard information can be obtained. And by collecting data in real time and updating the map, real-time updating and obtaining of the stockyard information can be realized.
