It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
Referring to fig. 2, a flow 200 of one embodiment of a vehicle dispatch method according to the present disclosure is shown, the vehicle dispatch method comprising the steps of:
In this embodiment, the order pool is a pool in which the order system stores orders in real time, and the products to be sorted stored in the warehouse and the storage positions of the warehouse corresponding to the products are determined by integrating orders of different times in the order pool.
The current transport vehicle is a cargo vehicle for loading products in an order from a warehouse, the cargo vehicle can be an autonomous guided vehicle or an autonomous mobile robot, before the current transport vehicle enters the warehouse, the layout of the warehouse is firstly input into the current transport vehicle, so that the current transport vehicle determines all storage positions in the warehouse, in which the products are stored, according to the layout of the warehouse, such as a storage position A in fig. 3, a plurality of tunnels are arranged in the warehouse, a plurality of storage positions are arranged in each tunnel, each storage position has a code with a certain format, and the codes are generally arranged through an arrangement layer, such as T-01-01-01, which indicates that the storage position is in a T tunnel, a row 01, a column 01 and a layer 01.
Before a current transport vehicle enters a warehouse to pick products, position information of products of an order issued by an execution main body on which a vehicle scheduling method is operated needs to be obtained, and the position information of the products comprises: after the current transport vehicle obtains the information of the product, a shortest running route can be planned for the position of the current transport vehicle, and the current transport vehicle is controlled to run in the warehouse based on the provided running route, so that the current transport vehicle carries out product loading in storage positions corresponding to different products based on the position corresponding to the order, and the purpose of picking the product is achieved.
The execution subject (for example, the server 105 shown in fig. 1) on which the vehicle scheduling method operates may obtain the current transport vehicle to be departed in the warehouse through the positioning device installed on the current transport vehicle, for example, obtain the layout map of the warehouse, obtain the signal of the positioning device on the user terminal (for example, the terminal devices 101, 102, 103 shown in fig. 1) at the entrance of the warehouse in real time, and determine the current transport vehicle to be departed.
In this embodiment, the current transport vehicle may be one transport vehicle or a plurality of transport vehicles, and the initial order is an order in the order pool before the current transport vehicle in the warehouse departs.
Based on the traditional method for pre-distributing the collection list for each transport vehicle, in the embodiment, all the initial order sets are combined to obtain the whole collection list, and then the orders are dynamically distributed for each transport vehicle, so that the order state of the current order pool can be comprehensively considered, the running route of each transport vehicle is optimized, and the transport vehicle is prevented from being blocked in the transport process.
Optionally, when all the initial orders are combined, all the initial orders may be further divided into different order subsets in the collection sheet according to the attribute and the source of each initial order and the storage location of the product corresponding to each initial order (for example, different sections of the corresponding warehouse, and initial orders belonging to the same section are combined to obtain subsets). And step 203, dynamically distributing the position information corresponding to the collection sheet to the current transport vehicle.
In this embodiment, the location information corresponding to the collection list refers to a product code (e.g., SKU) of each initial order in the collection list and a storage location of a warehouse corresponding to each product in the initial order.
Since the flow sorting system thoroughly breaks the concept of the collection list, based on the principle of flow sorting, in this embodiment, all orders to be placed are used as a whole collection list, and the whole collection list is dynamically allocated in real time, so that the use of the current transport vehicle can be combined with the flow sorting system, and the sorting path of the current transport vehicle is the simplest.
The current transport vehicle can be one transport vehicle or a plurality of transport vehicles, when the current transport vehicle is one transport vehicle, the product codes of all initial orders in the collection list and the storage positions of the warehouse corresponding to all products in all the initial orders can be allocated to the current transport vehicle, so that the transport vehicle can pick the products related to all the initial orders in the warehouse; optionally, according to the difference of the times of the initial orders in the collection list, the product code of the initial order closest to the current time and the storage position of the warehouse corresponding to each product in the initial order may be allocated to the current transport vehicle.
When the current transport vehicle is a plurality of transport vehicles, all initial orders in the collection list can be divided into different sub-order sets based on the positions, functions and the like of the transport vehicles, one sub-order set is distributed to each transport vehicle, and the product codes of the initial orders in the sub-order sets corresponding to the transport vehicles and the storage positions of the warehouses corresponding to the products in the sub-order sets are issued to the transport vehicles.
Optionally, for the sub-sets belonging to different warehouse sections in the collection sheet, the warehouse sections may be divided for each transport vehicle in advance (each transport vehicle is responsible for different warehouse sections), different sub-order sets are divided based on the different warehouse sections to which all initial orders belong in the collection sheet, a sub-order set corresponding to the section is allocated for each transport vehicle, and the product codes of each initial order in the sub-order set corresponding to each transport vehicle and the storage positions of the warehouse corresponding to each product in the sub-order set are issued to each transport vehicle.
As shown in fig. 3, in the travel route B of the carriage AMR1, the storage locations (r) of the warehouses having a plurality of corresponding products are distributed on the travel route.
In this embodiment, when the aggregate sheet is combined, the condition of the transport vehicle does not need to be considered in advance, and after the whole aggregate sheet is combined, different orders can be dynamically allocated to the current transport vehicle based on the information such as the number, the position, the parcel and the like of the current transport vehicle, so that each transport vehicle has an order set which is suitable for the current warehouse layout.
And 204, planning and issuing a running route to the current transport vehicle based on the position information corresponding to the collection list so that the current transport vehicle runs in the warehouse according to the running route.
In this embodiment, the operation route is determined by the initial order corresponding to the transport vehicle, and the operation routes formed by different initial orders are different. The current transport vehicle may be one transport vehicle or a plurality of transport vehicles, and the position information corresponding to each initial order forming the collection list may be one or more, so that the operation routes allocated to each transport vehicle in the current transport vehicle may be different. For example, when the current transport vehicle is a plurality of transport vehicles, the storage positions of the warehouses corresponding to all the products in all the initial orders can be evenly distributed to the transport vehicles, so that the running route of each transport vehicle is formed.
In this embodiment, when planning the operation route for the current transportation vehicle, only the position information corresponding to the collection sheet may be considered, so as to ensure that the current transportation vehicle may exhaust the storage locations of all products corresponding to the collection sheet in the warehouse.
Optionally, the execution subject on which the vehicle is scheduled to run may also plan a running route of the current transport vehicle based on the location information corresponding to the aggregate order and the layout of the warehouse, and issue the running route to the current transport vehicle. Therefore, the layout information of the warehouse is comprehensively considered, and the running route of the current transport vehicle can be more reasonably planned based on the actual layout structure of the current warehouse.
In this embodiment, the current transport vehicle may be one transport vehicle or multiple transport vehicles, when the current transport vehicle is one transport vehicle, the storage locations corresponding to the products of all the initial orders in the collection list need to be combined to form the running route, that is, the planned running route passes through the storage locations corresponding to the products of all the initial orders in the collection list, and further, when the planned running route has multiple routes, the route with the shortest running distance or shortest running time may be selected from the multiple routes as the final running route issued to the current transport vehicle. When the current transport vehicle is a plurality of transport vehicles, at least one initial order in the collection list is distributed for each transport vehicle in the current transport vehicle, an operation route is planned for each transport vehicle based on the initial order corresponding to each transport vehicle, the operation route of each transport vehicle needs to pass through the storage position of the product of the initial order corresponding to each transport vehicle in the process of planning the operation route, furthermore, when the initial operation route planned for each transport vehicle is a plurality of, an operation route with the shortest operation distance or the shortest operation time of each transport vehicle can be selected for each transport vehicle in the current transport vehicle based on the area of the warehouse corresponding to all transport vehicles in the current transport vehicle or the order quantity of all transport vehicles in the current transport vehicle, and therefore the operation route issued to each transport vehicle is guaranteed to be the optimal operation route.
Further, in this embodiment, the shape of the operation route may also be set when planning the operation route based on the warehouse layout and the transportation requirement of the transportation vehicle, as shown in fig. 3, the shape of the operation route B of the transportation vehicle AMR1 is S-shaped, and in fig. 3, the transportation vehicle AMR1 walks along the S-shaped operation route B, so that the shortest walking distance of the transportation vehicle AMR1 can be ensured.
In order to ensure the reliability of the picked product, the shape of the travel route may optionally also be a "not" shape. The 'non' -shaped running route can enable the route of the transport vehicle to be detailed to each storage position relative to the S-shaped running route, and although the running route has no optimization effect, each storage position can be guaranteed to be achieved.
And step 205, when the order is added in the order pool, issuing the position information corresponding to the added order to the current transport vehicle according to the order quantity and the position of the current transport vehicle.
In this embodiment, when the order in the order pool changes according to the order placing situation of the user, for example, the user places an order at any time, and the order in the order pool increases, that is, when the order pool has an increased order, based on the principle of dynamically allocating the location information corresponding to the aggregate to the transport vehicle in this embodiment, the location information corresponding to the increased order may be issued to the current transport vehicle in real time according to the location of the current transport vehicle (the location of the current transport vehicle in the operation route) and the order amount in combination with the operation route of the current transport vehicle.
In this embodiment, the order quantity is the quantity of the initial order allocated to the current transportation vehicle, and based on the order quantity and the rated quantity of the current transportation vehicle (the quantity of all orders that can be received when the current transportation vehicle normally operates at the current position of the current operation route), the quantity of orders that can be carried by the current transportation vehicle can be calculated, that is, it can be determined whether the order of the current transportation vehicle is saturated through the order quantity. If the order of the current transport vehicle is saturated (the order quantity is equal to the rated quantity), determining that the current transport vehicle can not bear the order task any more; and if the order of the current transport vehicle is not saturated, determining that the current transport vehicle can further carry out a transport task of adding the order. It should be noted that, because the current transportation vehicle is in a running state on the running route, the rated quantity of the transportation vehicle can take different values at different positions of the running route.
After the execution main body receives the order, if the current position of the current transport vehicle in the running route is not in the corresponding storage position of the order, and the current transport vehicle is in the state of unsaturated order at the current position, the position information corresponding to the order is sent to the current transport vehicle.
In this embodiment, the transport vehicle in the unsaturated state in the plurality of transport vehicles may be determined first, and then the position information corresponding to the addition order may be issued to the current transport vehicle based on the position of the transport vehicle in the unsaturated state. Specifically, in some optional implementation manners of this embodiment, the issuing, according to the order amount and the position of the current transport vehicle, the position information corresponding to the added order to the current transport vehicle includes: and responding to the fact that the current transport vehicle has the transport vehicle with the unsaturated order, and issuing the position information corresponding to the added order to the transport vehicle with the unsaturated order according to the position of the transport vehicle with the unsaturated order.
In the optional implementation mode, the order is added to the transport vehicles with unsaturated orders, so that each transport vehicle in the current transport vehicles can receive the order task to the maximum extent.
Optionally, when the current transport vehicle is a plurality of transport vehicles, the transport vehicles which do not run the storage locations corresponding to the added orders in the plurality of transport vehicles may be counted first, then, whether the transport vehicles which do not run the storage locations corresponding to the added orders are in an unsaturated state at their respective positions is detected, and finally, the transport vehicles which are in the unsaturated state and do not run the storage locations corresponding to the added orders are selected, and the transport vehicles which run the storage locations corresponding to the added orders are routed through the running route in the transport vehicles which are in the unsaturated state and do not run the storage locations corresponding to the added orders, and the position information corresponding to the added orders is issued to the selected transport vehicles. Therefore, an optional implementation mode is provided for the task of loading the order by the current transport vehicle, and the order is guaranteed to be processed in real time.
Optionally, when the current transport vehicle is a plurality of transport vehicles, the transport vehicles which do not run the storage locations corresponding to the added orders in the plurality of transport vehicles may be counted first, then, whether the transport vehicles which do not run the storage locations corresponding to the added orders are in an unsaturated state at respective positions is detected, finally, the transport vehicle which is in the unsaturated state and is not running the storage locations corresponding to the added orders and closest to the storage locations corresponding to the added orders in the transport vehicles which are in the unsaturated state and are not running the storage locations corresponding to the added orders is selected, and the position information corresponding to the added orders is issued to the selected transport vehicle. Therefore, another optional implementation mode is provided for the task of loading the order increase of the current transport vehicle, and the order increase is guaranteed to be processed in real time. The vehicle scheduling method provided by the embodiment of the disclosure comprises the steps of firstly obtaining an initial order of an order pool and a current transport vehicle to be started in a warehouse; secondly, combining all the initial orders to obtain a collection sheet; thirdly, dynamically distributing the position information corresponding to the collection sheet to the current transport vehicle; and planning and issuing a running route to the current transport vehicle based on the position information corresponding to the collection list so as to enable the current transport vehicle to run in the warehouse according to the running route. And finally, when the order is added in the order pool, issuing the position information corresponding to the added order to the current transport vehicle according to the order quantity and the position of the current transport vehicle.
