I. Industry background

Forklift trucks in the important position of warehousing logistics, ushered in a good development space, at the same time, diversified, intelligent logistics storage needs also put forward higher requirements for the development of forklifts. In recent years, forklift products from the serialization, diversification and green power technology development, but also more and more attention to the development and application of automatic identification technology in forklift, in improving the overall operation level of forklift applications, enhance the composite function, to ensure the basic power of forklift transport function at the same time, the pursuit of more added value, for the realization of intelligent forklift, intelligent logistics, intelligent storage plays an important supporting role.

RFID is a new automatic identification technology which transforms logistics distribution and product tracking management mode after bar code technology. Compared with the traditional automatic identification technology, RFID technology has good penetration, multi-label long-distance identification capability, large capacity of identifiable item information, repeated read-write, and the characteristics of one identification information, which is in line with the application of intelligent forklifts in warehousing logistics.

With the progress of society and the development of science and technology, the position of logistics equipment in economic development is becoming more and more obvious, and the popularity of forklift applications is getting higher and higher. Forklift trucks play a very important role in the warehousing logistics system of enterprises and are the main force in material handling equipment. This kind of trackless, tire walking loading and unloading vehicle is widely used in factories, mines, warehouses, stations, ports, airports, freight yards, circulation centers and distribution centers, etc., and can enter ship warehouses, carriages and containers to load and unload, stack, unstack and carry out short-distance transportation of finished pieces, packages, pallets and containers. It is an indispensable equipment for pallet transportation and container transportation.

II. System planning and design ideas

Forklift truck transport cargo carrier is mainly based on pallets, the use of Internet of Things technology logistics RFID forklift warehouse management system. ThingMagic industrial RFID reader, RFID antenna and industrial control computer are installed on the forklift to form an RFID reading system, and then RFID tags are used on the finished pallet to enable the intelligent forklift equipped with the RFID reading system to confirm the cargo information through the acquisition of RFID tag data when the pallet is forked, and to complete the uninterrupted tracking of the finished product information. Accurate location management provides basic information guarantee, and realizes intelligent, logistics RFID forklift warehouse management system.

Shenzhen Quanshun Hong Technology Co., Ltd. as RFID leading brand-ThingMagic agent, in the major operators, integrators to provide ThingMagic full range of products at the same time, the company has also been a professional technical team, quality service, preferential prices, to provide customers with more RFID equipment solutions and high-quality after-sales service. The company cooperates with major operators and integrators to successfully apply ThingMagic RFID equipment to various applications in various fields such as manufacturing, warehousing management, aviation shipping, clothing retail, anti-counterfeiting traceability, etc.

2.1 RFID reading system

RFID reading system composed of industrial computer, RFID reader and RFID antenna is the core part of forklift application. The schematic diagram is as follows:

2.2 RFID tray

RFID tray tags are installed in the tray to complete the binding of tags and trays.

2.3 RFID shelf

RFID shelf labels are installed on shelves to complete the binding of labels and shelves.

III. System workflow

After the enterprise warehouse management system WMS generates a new incoming and outgoing warehouse or transfer task, it will automatically issue the task to the intelligent forklift industrial PC that has not performed the task according to the operation of the intelligent forklift system. After the forklift worker starts the task, he will follow the instructions of the forklift PC to go to the designated shelf or warehouse gate to perform the task. In the process of performing tasks, Quanshun macro intelligent forklift RFID reading system will complete the confirmation of goods entering and leaving the warehouse or transferring goods according to the current task status, and the forklift driver does not need to intervene.

3.1 warehousing

During warehousing operation, the operator enters warehousing data in WMS, associates the information of the incoming goods with the pallet, and determines whether to specify specific location information according to the actual incoming goods. For the goods with specified location information, the forklift driver forks the pallet goods to the specified location under the instruction of the intelligent forklift industrial PC. When the pallet is placed and ready to be returned, the RFID reading system compares the read location information with the location information specified in the system. If it is correct, it will prompt the forklift driver to go to the correct goods.

For goods without specific location, forklift drivers can select appropriate location according to the empty status of location. After loading, Quanshunhong intelligent forklift RFID reading system automatically associates the read location label with the cargo pallet label, and uploads it to the background system to complete the loading of goods.

3.2 issue

During the delivery operation, after the operator reaches the delivery instruction on WMS, the industrial PC on the forklift will receive relevant tasks and guide the intelligent forklift driver to perform the delivery task. After the intelligent forklift picks up the pallet, Quanshun macro intelligent forklift RFID reading system can obtain accurate cargo information through the pallet label, and compare it with the outbound cargo information specified by WMS. If it meets the requirements, it will be allowed to leave the warehouse, otherwise it will alarm.

Issue and receipt is a reverse process operation.

3.3 transferred

Transfer refers to one-time issue and one-time receipt completed in the warehouse, and its general process control follows the principle of issue and receipt process control. The application of Quanshunhong ThingMagic Vega on forklifts provides intelligent forklift solutions, optimizes business processes for enterprises, improves work efficiency, not only ensures safe production, but also reduces the occupied labor force, greatly reduces labor intensity and greatly improves work efficiency. At the same time, real-time management of warehouse inventory is realized, and the operating cost of enterprises is reduced. The economic benefits are very significant.

IV. Recommended hardware selection

The application of RFID technology in forklifts has strict requirements for RFID equipment, including dustproof, waterproof and anti-vibration design, which can adapt to fluctuations in voltage and current. The equipment shell must be sturdy and durable, anti-corrosion, and at the same time, it should have good temperature adaptability. Suitable for all kinds of harsh environments.

1. RFID forklift reader

Quanshun ThingMagic-Vega is an industrial RFID forklift reader, it passed the automotive industry standard: TS16949, embedded high-performance M5e UHF RFID module, to meet the harsh environment operating standards, ideal for deployment in forklifts and various automotive applications.

2. RFID printer

UHF RFID barcode printer is used for staff to complete the initialization of standard paper labels in storage management card issuance, filing. Compared with traditional card issuing equipment, RFID printer has more efficient card issuing efficiency and simpler operation, which can help customers realize the initialization process of large quantities of labels in a short time. At the same time, other visual information such as barcodes can be printed on the label surface, so that the label has RFID function and good compatibility with the barcode system.
