Description

Technical Field

[0001] The present invention relates to the field of logistics control, and in particular to a control method for a fast-loading device. Background Art

[0002] With the increasing automation of logistics systems, automated equipment has gradually replaced manual labor in the handling of goods in many scenarios, reducing labor intensity.

[0003] As part of cargo handling, the fast-loading device transports cargo to the next stage via directional conveying structures, such as rollers. For example, a "Warenet Intelligent Mobile Cargo Receiving and Receiving Equipment and Control System" disclosed in Chinese patent literature, with publication number CN106966095A, includes transport equipment, three-dimensional grid shelves, a vertical lifting device, a belt conveyor, a scanner, an integrated chip control system, an all-in-one printer and scanner, and a human-machine interface. It can transport and store any solid item, as well as any liquid that can be placed in a solid container and any gas that can be placed in a solid container. Cargo inlets and outlets can be located between the main and co-driver cabs of the transport equipment or at any other location.

[0004] This solution utilizes automated, intelligent control and operation, eliminating the need for manual handling and significantly reducing labor intensity while improving efficiency. However, it fails to consider the nature of the cargo being transported. For example, fragile items cannot be stacked below other items, and the order of cargo must be considered during transportation. In practice, the control strategy for the fast-loading device cannot be adjusted based on the nature of the cargo, resulting in low efficiency. Summary of the Invention

[0005] The present invention mainly solves the problem that the existing technology does not take into account the properties of the transported goods themselves; it provides a control method for a fast-loading device, identifies the properties of the goods on the fast-loading device, formulates the order of cargo transportation according to the properties of the goods, reasonably allocates the cargo position, and improves the efficiency of cargo loading and unloading.

[0006] The above technical problems of the present invention are mainly solved by the following technical solutions:

[0007] A method for controlling a fast-loading device comprises the following steps:

[0008] S1: A fast-loading device for horizontal and vertical bidirectional transportation is installed in the carriage;

[0009] S2: Determine the loading and unloading stage of the cargo based on the cargo volume in the carriage;

[0010] S3: Scan cargo identification, identify cargo attributes, calculate the importance and priority of cargo, and determine the order of cargo transportation based on the cargo loading and unloading stages;

[0011] S4: Control the fast-loading device to transport goods in both horizontal and vertical directions according to the selected order of goods transportation, and monitor and record the corresponding positions of the goods.

[0012] By identifying the properties of the goods, we can determine the order of cargo transportation based on their properties, rationally allocate cargo locations, and improve cargo loading and unloading efficiency. We can also determine different cargo transportation orders based on the loading and unloading stages, which is more targeted and improves loading and unloading efficiency.

[0013] Preferably, the said fast-loading device for horizontal and vertical bidirectional transportation includes a horizontal conveyor belt and a longitudinal conveyor belt arranged on the fast-loading device platform; each fast-loading device is respectively provided with a control module that is interconnected and communicates with each other, and the control module controls the corresponding horizontal conveyor belt or longitudinal conveyor belt in sequence to transport the goods according to the selected order of goods transportation.

[0014] Goods are transported via horizontal and vertical bidirectional conveyor belts, making cargo transportation more flexible.

[0015] Preferably, the step S2 includes the following process:

[0016] S201: When the carriage door is open, image data inside the carriage is collected at a rated frequency; it is determined whether there is cargo in the carriage. If so, the process proceeds to step S202; otherwise, it is determined to be the loading stage;

[0017] S202: Compare the quantity of goods in the image data collected at the previous moment with the quantity of goods in the image data collected at the current moment; if the quantity of goods decreases, it is determined to be the unloading stage;

[0018] If the quantity of goods increases, it is judged to be the loading stage;

[0019] If the quantity of goods remains unchanged after the rated number of times, the process proceeds to step S203;

[0020] S203: Determine whether a loading or unloading command is received. If so, it is determined to be the loading stage when a loading command is received, and it is determined to be the unloading stage when an unloading command is received; otherwise, it is in a pending state and an alarm is issued, and the judgment returns to step S201 until the car door is closed.

[0021] The loading and unloading stages are determined according to the changes in the quantity of goods in the carriage, so that different loading and unloading sequences can be formulated in a more targeted manner.

[0022] Preferably, the cargo attributes include transportation distance, value, and transportation influencing factors; transportation influencing factors include fragile goods, flammable and explosive goods, corrosive goods, and ordinary goods. The importance and priority of each cargo attribute dimension are determined, and the loading and unloading order of the cargo is determined accordingly.

[0023] Preferably, the calculation process of the importance degree is:

[0024] Calculate the importance of the goods G based on the value of the goods and the transportation distance i ;

[0025]

[0026] Among them, G i Score the importance of the goods on the i-th pallet;

[0027] ω V is the value coefficient;

[0028] V i is the value of the goods on the i-th pallet;

[0029] is the average value of all goods;

[0030] ω L is the transport distance coefficient;

[0031] L i is the transportation distance of the goods on the i-th pallet;

[0032] L is the standard distance of the transportation journey.

[0033] The importance of goods is calculated based on their value and transportation distance. The greater the value, the higher the importance of goods; the longer the transportation distance, the lower the importance of goods.

[0034] Preferably, the priority calculation process is:

[0035] Classify goods according to factors affecting their transportation and count the quantity of each type of goods;

[0036] Calculate the priority D based on the quantity and importance of similar goods i ;

[0037]

[0038] Among them, D i is the priority of the goods on the i-th pallet;

[0039] M k is the total number of goods in category k corresponding to the goods;

[0040] M is the total number of goods.

[0041] The priority is calculated based on the quantity of the same type, which is used to determine which type of goods should be unloaded first during unloading.

[0042] As a preferred option, the unloading process during the unloading stage is:

[0043] Screen all cargo to be unloaded in the carriage;

[0044] The cargo to be unloaded is classified according to factors affecting transportation;

[0045] Sort the transport influencing factors by category from largest to smallest according to the average priority of the cargo to be unloaded in each category of transport influencing factors;

[0046] The cargo to be unloaded in the classification of various transport influencing factors is ranked from most important to least important;

[0047] Unload the cargo to be unloaded according to the sequence.

[0048] The same type of goods are unloaded in order of importance, and different types of goods are unloaded first according to their priority. This allows for more targeted loading of goods.

[0049] As a preferred method, the loading process during the loading phase is as follows:

[0050] A1: Determine whether there is cargo in the carriage. If so, proceed to step A2. Otherwise, load the cargo in descending order of importance.

[0051] A2: Compare the importance of the cargo to be loaded with that of the cargo in the carriage, estimate the loading location of the cargo to be loaded, and calculate the movement path;

[0052] A3: Perform weighted calculation based on the moving path and importance to obtain a new importance level;

[0053] A4: Return to step A2 until the moving path no longer changes;

[0054] A5: Load the cargo in ascending order of importance.

[0055] As an optimal method, the calculation process of the new importance degree is:

[0056]

[0057] Among them, G′ i is the new importance of the goods on the i-th pallet;

[0058] Y i is the number of fast-loading devices that the goods on the i-th pallet pass through;

[0059] Y c The number of fast-loading devices that the cargo in the carriage moves through;

[0060] Y0 is the standard value of the moving path.

[0061] The beneficial effects of the present invention are:

[0062] 1. By identifying the properties of the goods, the order of cargo transportation is determined according to the properties of the goods, the location of the goods is reasonably allocated, and the efficiency of cargo loading and unloading is improved.

[0063] 2. Formulate different cargo transportation sequences according to the cargo loading and unloading stages, which is more targeted and improves loading and unloading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0068] Example:

[0069] A control method of a speed-loading device in this embodiment is as follows: Figure 1 As shown, the following steps are included:

[0070] S1: A fast-loading device for horizontal and vertical bidirectional transportation is installed in the carriage.

[0071] In this embodiment, the bottom of the van or container is spliced and installed as shown in FIG. Figure 2 The quick-load device shown.

[0072] The fast-loading device of this embodiment is a fast-loading device capable of transporting in both horizontal and vertical directions. Figure 2 As shown, the rapid loading device includes a transverse conveyor belt 2 and a longitudinal conveyor belt 3 arranged on a rapid loading device platform 1.

[0073] The transverse conveyor belts 2 are respectively arranged on both sides of the fast-loading device platform 1; the longitudinal conveyor belt 3 is perpendicular to the transverse conveyor belt 2, and the longitudinal conveyor belt 3 is arranged between the two transverse conveyor belts 2, and the distance between the longitudinal conveyor belts 3 is adapted to the distance between the support legs at the bottom of the pallet 4.

[0074] Each fast-loading device is equipped with a control module that is interconnected. In this embodiment, the control module is located at the bottom of the fast-loading device platform 1. The control module controls the corresponding transverse conveyor belt 3 or longitudinal conveyor belt 2 to transport the goods according to the selected cargo transportation sequence.

[0075] The use of bidirectional conveyor belts to transport goods makes transportation more flexible and facilitates the change of the relative position of goods in the carriage.

[0076] S2: Determine the loading and unloading stage of the cargo based on the cargo volume in the carriage.

[0077] S201: When the carriage door is opened, image data inside the carriage is collected at a rated frequency;

[0078] Determine whether there is cargo in the carriage. If so, proceed to step S202 for determination; otherwise, determine that it is the loading stage.

[0079] Once the carriage door is opened, it can be determined whether the cargo is being loaded or unloaded, reducing unnecessary judgment during transportation and lowering energy consumption. Image recognition is used to determine whether the carriage is loaded or not, making it simple and convenient.

[0080] S202: Compare the quantity of goods in the image data collected at the previous moment with the quantity of goods in the image data collected at the current moment.

[0081] If the quantity of goods decreases, it is considered to be the unloading stage;

[0082] If the quantity of goods increases, it is judged to be the loading stage;

[0083] If the quantity of goods remains unchanged after the rated number of times, the process proceeds to step S203 for determination.

[0084] S203: Determine whether a loading or unloading command is received. If so, it is determined to be the loading stage when a loading command is received, and it is determined to be the unloading stage when an unloading command is received; otherwise, it is in a pending state and an alarm is issued, and the judgment returns to step S201 until the car door is closed.

[0085] The loading and unloading stages are determined according to the changes in the quantity of goods in the carriage, so that different loading and unloading sequences can be formulated in a more targeted manner.

[0086] S3: Scan cargo identification, identify cargo attributes, calculate the importance and priority of the cargo, and determine the order of cargo transportation based on the cargo loading and unloading stages.

[0087] Each pallet is equipped with a cargo identification card with cargo information recorded. Cargo identification cards include QR codes, RFID, barcodes, etc., and the corresponding cargo attribute information is obtained by scanning.

[0088] Cargo attributes include transportation distance, value and transportation influencing factors.

[0089] Factors affecting transportation include fragile goods, flammable and explosive goods, corrosive goods and ordinary goods.

[0090] Determine the importance and priority of different cargo attributes and formulate the order of loading and unloading of cargo accordingly.

[0091] The calculation process of importance is:

[0092] Calculate the importance of the goods G based on the value of the goods and the transportation distance i ;

[0093]

[0094] Among them, G i Score the importance of the goods on the i-th pallet;

[0095] ω V is the value coefficient;

[0096] V i is the value of the goods on the i-th pallet;

[0097] is the average value of all goods;

[0098] ω L is the transport distance coefficient;

[0099] L i is the transportation distance of the goods on the i-th pallet;

[0100] L is the standard distance of the transportation journey.

[0101] The importance of goods is calculated based on their value and transportation distance. The greater the value, the higher the importance of goods; the longer the transportation distance, the lower the importance of goods.

[0102] The priority calculation process is:

[0103] Classify goods according to factors affecting their transportation and count the quantity of each type of goods;

[0104] Calculate the priority D based on the quantity and importance of similar goods i ;

[0105]

[0106] Among them, D i is the priority of the goods on the i-th pallet;

[0107] M k is the total number of goods in category k corresponding to the goods;

[0108] M is the total number of goods.

[0109] The priority is calculated based on the quantity of the same type, which is used to determine which type of goods should be unloaded first during unloading.

[0110] The loading process during the loading phase is as follows:

[0111] A1: Determine whether there is cargo in the carriage; if so, proceed to step A2; otherwise, load the cargo in order of importance, from least important to least important.

[0112] A2: Obtain and compare the importance of the cargo to be loaded with the importance of the cargo in the carriage, estimate the loading location of the cargo to be loaded, and calculate the movement path.

[0113] A3: A new importance level is obtained by performing a weighted calculation based on the moving path and the importance level.

[0114] The new importance level is calculated as follows:

[0115]

[0116] Among them, G′ i is the new importance of the goods on the i-th pallet;

[0117] Y i is the number of fast-loading devices that the goods on the i-th pallet pass through;

[0118] Y c The number of fast-loading devices that the cargo in the carriage moves through;

[0119] Y0 is the standard value of the moving path.

[0120] A4: Return to step A2 until the moving path no longer changes.

[0121] A5: Load the cargo in ascending order of importance.

[0122] The unloading process during the unloading phase is as follows:

[0123] B1: Screen all cargo to be unloaded in the carriage;

[0124] B2: Cargo to be unloaded is classified according to factors affecting transportation;

[0125] B3: Sort the transport influencing factors by category from largest to smallest according to the average priority of the cargo to be unloaded in each category;

[0126] B4: Rank the cargo to be unloaded in descending order of importance among the various transport influencing factors.

[0127] B5: Unload the cargo to be unloaded according to the order.

[0128] The same type of goods are unloaded in order of importance, and different types of goods are unloaded first according to their priority. This allows for more targeted loading of goods.

[0129] S4: Control the fast-loading device to transport goods in both horizontal and vertical directions according to the selected order of goods transportation, and monitor and record the corresponding positions of the goods.

[0130] Record cargo information on the corresponding quick-loading device, including location, importance, and priority, to facilitate subsequent cargo loading and unloading.

[0131] By identifying the properties of the goods, we can determine the order of cargo transportation based on their properties, rationally allocate cargo locations, and improve cargo loading and unloading efficiency. We can also determine different cargo transportation orders based on the loading and unloading stages, which is more targeted and improves loading and unloading efficiency.
