Due to the needs of forklifts, automated warehouses, and different processes in different warehouses, the requirements for project integration are very high. The requirements for accessories for this project are very high and the quantity is relatively large. In our list, there are as many as two hundred items, mainly including the storage battery on the forklift, the power supply for the tablet and the RFID reader, and the constant current and constant voltage automatic charger for charging the battery because of the high shelf. For forklift operations, we chose the Bluetooth solution for wireless communication.
Main RFID auxiliary equipment and accessories
It is worth mentioning that, in order to facilitate the physical integration of forklifts and automation facilities, we independently designed a load-bearing bracket made of aluminum alloy steel material. It is very flexible to use and configurable. It can realize fast and cheap reconfiguration to support continuous Changing application requirements, such as pallet label reading, shelf label reading, and conversion to box level reading, are faster and cheaper to install and deploy. It can be replaced quickly after damage, and will not cause problems during busy periods and will not affect work efficiency.
For this test, we have prepared many types of RFID electronic tags for different processes in automated, semi-automated, and flat warehouses, and they must be affixed to different positions such as pallets, floors, and shelves. There are labels in PVB, paper, plastic, and ceramic packages. The installation method requires screws, rivets, super glue, cable ties, or double-sided tape.
Various types of shelves, pallets, floor labels
In addition, the debugging of RFID hardware equipment, the development of RFID middleware and application software, and the debugging of communication methods are also required. After the management and coordination of the project manager and the efforts of the team members, all the tasks are in order. Unfold.
Summary of the test process:
After intensive test preparations, we began to enter the site for testing. The team members tested the low-temperature environment of the cold storage. The corridors of the warehouse were minus four to five degrees Celsius, and the internal temperature of the warehouse was minus 20 degrees Celsius. The continuous implementation of the test plan required four Five working days. The testing process is mainly the installation of equipment, deployment of scenarios, testing of different scenarios, different types of warehouses, and problems found in the process and solutions. Let’s give you a simple graphic introduction from the entry to the end.
(1) First of all, it is the scene of personnel and equipment entering the warehouse. We have prepared three lifting boxes to hold the main precision equipment. After arriving in the warehouse corridor, we will prepare for the equipment installation. The following picture shows the real shot scene:

(5) The next “exciting” RFID test in the library began, because here is minus 20 degrees Celsius! The team also put on gloves, hats, and thickened a layer of clothing. After entering the warehouse, the first thing to be done is to place RFID electronic storage tags on the shelves, which must be installed on each layer. According to our experience at different heights, the corresponding reading effect is definitely different.
Place RFID tags on shelves
After the RFID cargo location tag is installed, the loading and unloading tests are carried out. After the goods are put into the warehouse according to the process, the goods enter the stocking area first, and then the forklift loads the goods reading tags, and the location information of the goods is obtained from the Smart WMS and displayed on the tablet computer. Then carry out the shelf operation, scan the goods label first, and then scan the cargo location label. The data is communicated with the database through the wireless network, and the data is compared. After the accuracy is correct, the shelf is completed.
The removal operation is to find the location and the goods according to the task, carry out the scanning operation respectively, and then complete the removal operation. During the test, we adjusted the corresponding RFID middleware, parameter settings, and antennas for reading pallet tags and shelf tags. After a day and a half of testing, we completed this part of the test.
