1. Background
With the continuous expansion of the scale of the city and the continuous development of the economy, the retail industry is also constantly developing and progressing. Generally speaking, the scope of the city is relatively small, just because of the economic mileage of the car. Therefore, the urban distribution center was born to serve the retail industry.
As the urban distribution center uses fewer batches, multiple batches, multiple varieties, and multiple users, this determines the complexity and flexibility of the urban distribution center.
Compared with other distribution centers, the focus of urban distribution centers is reflected in the speed of picking and shipping. How to accurately and quickly respond to task requirements has become a problem facing every urban distribution center.This article tries fromRFIDFrom a technical point of view, a set of solutions are proposed to effectively solve the problems faced by enterprises.
2. Introduction to RFID technology
Radio Frequency Identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets . Because of its functional characteristics, it has been widely used in many fields, especially the field of warehouse management system. Tianjin Bee has been engaged in the application research of RFID technology for a long time, especially focusing on the research and development of RFID warehouse management system.
2. Program composition
This solution is mainly used for the automated identification management of bulk goods in storage, storage, sorting and outbound in the distribution center. It consists of radio frequency tags installed on goods or pallet turnover boxes, radio frequency identification systems installed in each link of the distribution center process, Middleware and warehouse management system software composition. When the tagged target passes through the set signal collection point, the tag immediately emits a radio frequency signal with representative identity characteristics, which is received by the system, processed by middleware, and sent to the warehouse management system. The RFID warehouse management system sends a series of messages Instructions to realize the functions of information collection, storage in warehouse, regular inventory, sorting out of the warehouse, etc. of the goods.
Three, the program process
According to the distribution center process, an electronic label is fixedly installed on each pallet, turnover box or goods, and the information of the goods on the pallet or turnover box iselectronic labelBundle the input database.
1. An identification system is installed at the entrance of the distribution center, and the relevant information carried by the electronic tag on the pallet is captured and transmitted to the RFID warehouse management system. The system arranges the storage location according to the cargo location information.
2. An identification system is installed in the picking area of the distribution center to read/write the information of the picked goods into the electronic label on the turnover box.
3. An identification system is installed in the sorting area of the distribution center to realize automatic recheck and out of the warehouse while the goods are diverted.
4. The forklift truck body is equipped with an identification system to identify the relevant information carried by the electronic label on the pallet, and perform corresponding operations based on the information.
Fourth, the program advantages
1. The pallets and turnover boxes are labeled and reused once.
2. Optimize and adjust the distribution center process, the information anti-collision function of the automatic identification system, can read multiple different tags, realize the automatic review of the outbound, greatly improve the outbound speed, and reduce the labor cost of the distribution center.
3. Accurate inventory management enhances the planning, turnover, and distribution capabilities of the distribution center, and reduces losses and adjustment costs.
4. Research surface: The application of RFID solutions can increase the efficiency of the distribution center by 10% to 20%, while the inventory and delivery accuracy can reach 100%.
