technical field

The invention relates to the technical field of information identification and processing, in particular to a logistics automatic sorting system based on a two-dimensional code.

Background technique

In recent years, my country's e-commerce has developed rapidly, more and more people are accustomed to online shopping, and the business volume of the express delivery industry is also increasing day by day. The surge in business volume has also brought many new challenges to the express delivery industry. Among them, how to ensure the speed and reliability of the sorting process is a very important issue. At present, most small third-party logistics express companies in China still use the traditional sorting method, which mainly relies on a large amount of manpower to sort express items, which is not only inefficient, but also has a high error rate. There are also many logistics companies using modern automatic sorting methods, such as applying automatic identification technology represented by barcodes and RFID to automatic logistics sorting, which greatly improves the sorting efficiency. The patent "Automatic sorting device for express parcels based on barcode" (patent application number: 2012201107144) describes an automatic sorting device based on one-dimensional barcodes. The scanner and control chip achieve the purpose of automatic sorting. However, one-dimensional barcodes have the disadvantages of small data capacity, can only represent simple Arabic numerals or letters, and have strong directionality in scanning and reading, so their use has been greatly limited. The patent "An RFID-Based Item Sorting System" (patent application number: 2012200402788) describes an RFID-based automatic sorting system. Communication module, control center and sorting equipment to achieve the purpose of automatic sorting. It is undeniable that RFID technology is very suitable for logistics due to its efficient reading and writing characteristics, but RFID tags are costly and cannot be read after damage, and are prone to crosstalk in complex metal structures, which may require a lot of continuous investment for logistics companies. There will be benefits only when there is a large cost, and it is difficult to promote and apply. As a widely used information carrier nowadays, the two-dimensional code has the characteristics of large storage capacity, can store Chinese characters, high confidentiality, strong resistance to damage, and 360-degree identifiable characteristics. These characteristics determine that it is very suitable for use in the logistics industry. .

The present invention aims at the above-mentioned problems existing in the prior art, and provides an automatic sorting system based on two-dimensional codes. Using the above-mentioned characteristics of two-dimensional codes, it can solve the problems of high labor cost, low efficiency, and reliability in manual methods. It can avoid the shortcomings of poor performance, and can well avoid some defects of one-dimensional barcode and RFID technology itself.

The technical solution of the present invention to solve the above technical problems is: an automatic sorting system based on a two-dimensional code, characterized in that the system includes: a two-dimensional code scanning module, an information processing module, an infrared sensing module, a single-chip microcomputer, and a sorting device , the two-dimensional code scanning module scans and reads the two-dimensional code information containing the target parcel sorting number, recipient name, address, and telephone number, and sends it to the information processing module, which extracts the target parcel sorting number from it, and passes The coding rule analyzes the sorting number to determine the destination of the target parcel, that is, to determine the exit of the conveying device for parcel sorting, and then send this control signal to the single-chip microcomputer. The infrared sensing module is installed at the beginning of the conveying device of the sorting equipment. When the package passes through the infrared sensing module, the infrared sensing module will immediately send a reference signal to the single-chip microcomputer, and the single-chip microcomputer calculates how long after the reference signal passes to control the swing arm work of the transmission exit. When the target package arrives at the corresponding sorting outlet, the swing arm is just started to send the package into the corresponding sorting equipment conveyor.

The work of controlling the sorting equipment specifically includes that the information processing module sends a control signal to the single-chip microcomputer according to the sorting number of the target package, and determines the exit of the delivery device for package sorting. When the package passes through the infrared sensor module, the infrared module will generate a sense and generate a reference signal, the single-chip microcomputer calculates the time when the target package reaches the corresponding sorting exit according to the reference signal, and controls the start time of the swing arm. When the target package arrives at the corresponding sorting outlet, the swing arm starts exactly. Send the package to the corresponding sorting equipment conveyor.

The present invention uses two-dimensional codes as information carriers, which not only solves the shortcomings of one-dimensional barcodes such as small storage capacity, inability to store Chinese characters, and strong directionality for recognition, but also avoids the high cost of RFID. Since the two-dimensional code stores a lot of information, the reliability of sorting is improved by using the sorting number included in the two-dimensional code.
