Bluetooth AoA Positioning Technology-Logistics and Warehousing

01 Background

the background of accelerating the pace of economic globalization and increasingly complex logistics activities, warehousing logistics, as the central link of the process of goods circulation, has increasingly become the key to determine the development of enterprises and the competitiveness of the industrial chain. Manufacturing, electric commerce, third-party logistics and other types of logistics in the port terminal, warehouse operation scene, through the combination of indoor positioning technology and RFID, two-dimensional code, so that every element in the turnover process can be perceived and tracked, combined with the continuous optimization of the big data analysis platform for analysis, so that the logistics capacity of enterprises to further optimize and improve.

02 Indoor Positioning Technology in Warehouse Logistics Scene

Indoorpositioning technology in warehousing logistics is mainly reflected in the following aspects:

cargo real-time dynamic and orderly management.uses Bluetooth AoA positioning technology to carry out real-time, dynamic and orderly management of many quantities and varieties of materials in warehousing and logistics, realizing the intelligent management level and material circulation speed of the processes of material warehousing, outbound, movement, inventory checking, searching, etc., and avoiding to the greatest extent long warehousing acceptance time, random inventory checking in the warehouse and inaccurate quantity, long outbound picking time and frequent picking of wrong goods, and claims for damaged, lost or overdue goods. Based on the precise positioning of each cargo, combined with CV (computer vision), abnormal goods that are damaged or slip off the slide can be quickly located, and early warning can be given to operations such as blocked slide openings and unsmooth transportation. At the same time, the layout rationality of the shelting operation and the best path combination of picking can be optimized for warehouse shelting management, and when the goods are transferred to the sorting center, the goods can be effectively prevented from being sorted to the wrong outlets or sorting centers.

Intelligent scheduling and safety management of vehicle equipment.For logistics warehouses and ports with large storage capacity, large circulation capacity and large floor area, the overall management of forklift/trailer is realized through Bluetooth AoA positioning technology, and the utilization efficiency of forklift/trailer is improved by realizing intelligent allocation and reasonable path planning to prevent dislocation. By setting safe distance and electronic fence, human-vehicle collision accidents can be prevented to the greatest extent. Bluetooth AoA precise positioning makes the management of forklifts, ground cattle and cage cars in the warehouse simpler and more operable. In terms of practical application, such as loading and unloading, palletizing, short-distance transportation of pallet goods during forklift operation, reverse search of vehicles, path planning and navigation, etc., as well as real-time accurate location tracking based on Bluetooth AoA can be used for the safety of people and vehicles, vehicle safety, and reduce accidents in the warehouse.

efficient people management.Based on the real-time positioning data of personnel, personnel attendance, working hours statistics, on-duty/off-duty and other work status management. With the blessing of Bluetooth AoA precision positioning technology, it can improve the accuracy of real-time scheduling, operation area management and safe channel aggregation early warning of warehouse staff. For example, the common review and picking operations in the warehouse can be optimized in advance according to the location of personnel and packages to optimize the cost of picking goods. At the same time, continuously record the trajectory information of personnel, and do data analysis with the picking behavior of goods, and continuously optimize the picking path recommendation results through unsupervised learning. At the same time, through the presentation of personnel heat, it can also assist the management personnel in the warehouse to make a more reasonable manpower layout and do business management such as attendance.

Vehicle Management and Automation.the positioning of movable shelves, pallets, bins and other vehicles carrying goods, through the effective management of the vehicles, the orderly management of their carrying goods is indirectly realized. In addition, in the face of AGV and other automation equipment is more and more widely used today, positioning technology can be used to realize the efficient cooperation between AGV and vehicles, realize automatic pick-up and other functions, and further release the value of automation equipment.

3) Bluetooth AoA positioning technology advantages

high-precision Bluetooth AoA positioning technology inaccuracy, power consumption, coverage, compatibilityand other aspects of comparison UWB advantages:

equivalent or better accuracy at the same deployment density

is 30~50cm, which can meet the needs of the field environment.

Bluetooth AoA positioning technology very low power consumption

beacons can reach more than 1 year (button battery powered), and the use time of UWB beacons is usually between 1 week and 1 month under the same battery capacity.

single base station to achieve two-dimensional positioning

AoA single base station can be accurate two-dimensional positioning, single UWB base station to do presence detection.

is oriented to sub-meter positioning of ordinary mobile phones and supports WeChat applet positioning

Bluetooth AoA positioning can be compatible with existing mobile phones, and existing mobile phones basically do not support UWB.

Summary:in the warehouse logistics operation scenario, the location information is mainly used to improve the storage order and material circulation efficiency, the positioning accuracy has higher requirements, the positioning terminal or positioning label requires small size, low power consumption, especially for the positioning terminal on the goods. Therefore, AoA positioning technology based on low-power BLE Bluetooth has great technical advantages in logistics and warehousing applications. Logistics warehousing application scenarios combined with 5G, positioning, IoT, AI and other technologies, to promote the development of logistics intelligence, and jointly drive the logistics industry to reduce cost efficiency.
