Referring to fig. 2, fig. 2 is a schematic diagram of a connection relationship between logistics distribution and scheduling systems based on a digital twin according to an embodiment of the present invention, for showing a relationship between modules of the logistics distribution and scheduling systems.
Referring to fig. 3, fig. 3 is a schematic flow chart of preparing a distribution plan by using a digital simulation model according to an embodiment of the present invention, specifically, the preparing a distribution plan by using digital simulation according to the distribution plan may include the following steps:
s301: and obtaining the communication equipment to be distributed, the logistics transportation vehicle and the loading equipment in the logistics resource library module according to the distribution plan.
S302: and the digital simulation module acquires the digital models corresponding to the communication equipment to be distributed, the logistics transport vehicle and the loading equipment from the digital model library module, performs digital simulation in a virtual space, and loads the digital models corresponding to the communication equipment to be distributed into the digital models corresponding to the logistics transport vehicle by using the digital models corresponding to the loading equipment.
Specifically, according to a preset algorithm, a digital simulation module is used for solving a three-dimensional loading problem and generating a preliminary loading scheme, wherein the preset algorithm comprises a genetic algorithm and/or an orthogonal binary tree search algorithm;
specifically, the digital simulation module solves a three-dimensional loading problem to generate a preliminary loading scheme, wherein the constraint conditions comprise carriage capacity and vehicle load, and the optimization targets comprise maximum load capacity, maximum space utilization rate, minimum vehicle quantity and the like. The general algorithms for solving the three-dimensional loading problem are many, and include a genetic algorithm, an orthogonal binary tree search algorithm and the like.
And according to the preliminary loading scheme, loading the digital model corresponding to the communication equipment to be distributed into the digital model corresponding to the logistics transport vehicle by using the digital model corresponding to the loading equipment.
Specifically, the digital simulation module uses a digital twin technology to load the digital model of the communication device into the digital model of the vehicle by using the digital model of the loading device according to a preliminary loading scheme, and currently, mainstream logistics simulation software (such as Incontrol) supports digital simulation of the loading process of the communication device. The digital simulation aims to verify the applicability of the communication equipment in the loading process and optimize the loading sequence of the communication equipment. And if the digital simulation verification is not feasible, skipping to solve the three-dimensional loading problem by using a digital simulation module according to a preset algorithm, and generating a preliminary loading scheme for solving again.
The logistics of communication devices to be delivered are characterized by very different (e.g. volume, weight) and mixed transportation of single vehicles, and the logistics transportation path can be loaded at multiple delivery points, which will cause two problems: firstly, the loading equipment at the delivery point may not match the loading scheme, and the unloading cannot be effectively carried out; secondly, after partial communication equipment is unloaded in the transportation process, the gravity center of the logistics transportation vehicle is changed, and risks of communication equipment toppling and vehicle rollover exist in a subsequent transportation path. Therefore, a digital twin technology is needed to carry out digital simulation of logistics transport vehicle transport, a digital model of a vehicle travels according to a logistics transport path, a digital model of a loading device digital model is used at each delivery point to unload the digital model of the communication device, feasibility and efficiency of unloading of the communication device are verified, stability of the vehicle in the traveling process is verified, the digital simulation in the traveling process relates to a digital map and vehicle dynamics, in the digital simulation process, if the fact that the loading device at a certain delivery point is not suitable for use is verified, or risks of toppling over of the communication device and rollover of the vehicle exist in a certain section of the transport path, skipping is carried out according to a preset algorithm, a three-dimensional loading problem is solved by using a digital simulation module, and a preliminary loading scheme is generated to be solved again.
S303: and the digital simulation module generates a distribution scheme according to the digital simulation result.
Specifically, the digital simulation module generates a distribution scheme according to the digital simulation result, wherein the distribution scheme comprises logistics transport vehicles, used loading equipment, communication equipment to be distributed, arrangement of the communication equipment to be distributed in a vehicle cargo box and a loading sequence of the communication equipment to be distributed.
It should be noted that the digital simulation module performs digital simulation of transportation of the logistics transport vehicle according to the preliminary loading scheme and the logistics transport path, unloads the digital model of the communication device to be delivered at each delivery point by using the digital model of the local loading device, verifies the feasibility and efficiency of unloading of the communication device, verifies the stability of the logistics transport vehicle and the communication device in the subsequent transportation path, and optimizes the preliminary loading scheme according to the digital simulation result to generate the delivery scheme.
The monitoring module is used for monitoring the real-time state of the logistics transport vehicle after the unloading of the communication equipment to be delivered is finished in real time, updating the digital model in the virtual space, continuously performing digital simulation on the logistics process in the subsequent transport path, and optimizing the subsequent delivery scheme when the digital simulation result is abnormal.
In particular, the distribution scheme in the digital space is not always strictly implemented in the physical space, for example, due to the deviation of the placement position of the communication equipment (which is most likely to occur after the communication equipment is unloaded at the delivery point), the deviation of the transportation path (lane sealing and lane changing), the difference between the corresponding digital twin models in the physical entity and the virtual space, and the digital simulation result is no longer reliable. Therefore, the monitoring module transmits the real-time states of the logistics vehicles and the communication equipment in transportation to the digital simulation module, the digital simulation module updates the digital twin model by using real-time data and continuously performs digital simulation, and when the digital simulation prompts that safety risks exist, the risk prompts are sent to logistics personnel through the scheduling module.
Illustratively, according to an initially planned logistics transportation path, the logistics transportation can be safely transported through verification after digital simulation, but as the transportation path is changed due to road closure during transportation, a large curve exists in a certain road section of a new path, the digital simulation result shows that if the highest speed limit is carried out according to the road, the vehicle rollover risk possibly exists due to the fact that the gravity center of communication equipment is higher, and at the moment, the digital simulation module sends a notice to the scheduling module to prompt logistics personnel to pass at a low speed.
The logistics distribution and scheduling system based on the digital twin comprises an order processing module, a logistics resource library module, a digital model library module, a digital simulation module, a scheduling module and a monitoring module, wherein a digital model is created in a virtual space for each communication device by utilizing the digital twin technology, digital simulation is carried out on the whole logistics transportation process, a distribution plan is optimized, and the transportation reliability of the communication devices is improved.
