Logistics automation plays an important role in all levels of logistics management. It includes various soft and hard technologies such as logistics planning, logistics information technology and automatic logistics systems. Logistics automation plays a very important role in all walks of life in the national economy and has great development potential. With the continuous increase in research efforts, logistics automation technology will further develop in terms of informatization and greening, and its various technical equipment and management software will also be further developed and applied.

[0003] Traditional express sorting methods require manual participation, are inefficient and prone to errors. In the existing express logistics system, the sorting and delivery process becomes complicated due to the different sizes, shapes and weights of express items. Traditional express delivery control systems are often unable to accurately control the delivery of express items of different sizes, resulting in low sorting efficiency and even possible damage or loss of express items. Linear narrow-band machines or narrow-band sorting machines are increasingly used in the sorting field. Due to the limited width of the narrow band, one express often requires several adjacent narrow bands to be driven together. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an express sorting control system suitable for express items of different sizes, which solves the problems mentioned in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an express sorting control system suitable for express items of different sizes, including a conveying system, a control system and a control terminal. The conveying system, the control system and the control terminal are bidirectionally connected via wireless. The control system transmits data to a large database for storage. The control system receives image data transmitted from an EDP camera, and the conveying system and the EDP camera are powered by a power module.

[0006] Preferably, the conveying system includes an annular conveying assembly, which includes a frame, a trolley control unit and a drive assembly. The trolley control unit includes a trolley, a belt and a control center, and the trolley and the belt are both controlled by the control center. The trolley control unit is connected to the surface of the frame by transmission, and multiple trolley control units are provided. The drive assembly drives the trolley control unit to move on the frame.

[0007] Preferably, the control system includes a picture receiving module, which receives the captured picture and transmits it to the picture processing module, which processes the picture for clarity and then transmits it to the picture recognition module, and the picture recognition module recognizes the picture and then transmits it to the central processing system.

[0008] Preferably, the central processing system controls the PLC to work, the PLC directly controls the trolley control unit, and the central processing system determines the location of the express on the picture through the trolley number determination module. After the trolley number determination module determines the number, the trolley is bundled through the trolley bundling module to form a temporary transport group, and the bundling information is transmitted to the central processing system.

[0009] Preferably, the central processing system transmits the data to the control terminal through the data transmission module, and stores the data through a large database.

[0010] Preferably, the trolley corresponds to two groups of belts, and the number of belts in one group of belts is two.

[0011] Preferably, the control method of the express sorting control system applicable to express items of different sizes specifically includes the following steps:

[0012] S1. Identification and positioning of express parcels: Use EDP cameras to scan the express parcels on the conveyor system in real time, and use image processing technology to identify the specific location of the express parcels on the transportation line, that is, determine which adjacent belts the express parcels fall on;

[0013] S2. Cart allocation and bundling: Based on the identified express delivery location, the car number determination module determines the location of the express delivery on the picture, and bundles the cars that need to participate in the delivery through the car bundling module to form a temporary delivery team. The bundling process is achieved through wireless communication technology to ensure real-time communication and collaborative work between cars.

[0014] S3, unified action control: PLC sends instructions to the trolley control unit according to the recognition results and the assigned trolley information. After receiving the instructions, the trolley control unit immediately executes the corresponding action. During the action execution, the trolleys maintain real-time communication to ensure the consistency and coordination of the actions. The trolleys transport the express through the belt transmission;

[0015] S4. Delivery completion and trolley release: When the trolley delivers the express to the designated location and completes unloading, the system detects the status of the express through sensors. When it detects that the express has left the trolley and is stably placed at the designated location, it is determined that the delivery is completed. The PLC sends a command to the trolley control unit to release the bundled trolley. After the trolley is untied, it returns to the standby state and waits for the next delivery task.

[0016] Beneficial Effects

[0017] The present invention provides an express sorting control system suitable for express parcels of different sizes. Compared with the prior art, it has the following beneficial effects: the express sorting control system suitable for express parcels of different sizes realizes bidirectional connection between the conveying system, the control system and the control terminal through wireless, the control system transmits data to a large database for storage, the control system receives image data transmitted from an EDP camera, and the conveying system and the EDP camera are powered by a power module, and can be bundled together for operation through a trolley. According to the size of the express, the trolley number occupied by the express is determined, and these trolleys can be driven to sort the express, which solves the problem of narrowband machines, and can sort parcels of different sizes, thereby improving its versatility, and realizing automatic delivery of express parcels through the EDP camera. Identification improves the intelligence level of the system. By intelligently allocating delivery carts and uniformly controlling the execution of actions by the carts, the sorting and delivery efficiency is improved. The intelligent express delivery control system can greatly improve the sorting efficiency, reduce manual intervention, and reduce the error rate through real-time scanning, automatic allocation of carts, and unified control of actions. It can handle express items of different sizes, shapes, and weights and has strong adaptability.
