1) Scenario requirements
The logistics industry has intensive personnel operations, unmanned facilities have also been infiltrating, but for a considerable period of time, a large number of warehouses still exist personnel intensive operations, frequent asset turnover, warehouse person-vehicle mixed operations, there are the following pain points: 1) Personnel: It is difficult to effectively monitor and count staff time, staff busy and idle state, staff leaving the post alarm, and further optimize staff performance management; 2) Production: It is difficult to grasp the location information of personnel and various logistics assets (pallets, containers, warehouse vehicles, etc.), and realize efficient personnel and asset production scheduling management; In complex warehouse environment, new people, including warehouse picking and other links of staff, forklift drivers, etc., work efficiency is low; 3) Assets and goods: logistics assets and goods are inconvenient to locate and find; 4) Safety: vehicle and personnel positioning and collision warning. This chapter describes the solutions and business application scenarios based on Jingdong logistics positioning practice.
2) Solution ideas
The introduction of 5G+ Bluetooth 5.1 positioning integration technology will integrate the positioning system with the business management and control process to realize the intelligent upgrade of personnel, materials and security management.
The fusion scheme of 5G networking and positioning networking is shown in the following figure. High-precision positioning adopts Bluetooth AoA high-precision positioning technology, which can locate requirements at full cost, low power consumption, multi-type terminals, and sub-meter level. The location solution engine is deployed in the MEC, receives the data sent back by the positioning micro-base station through the 5G channel, and solves the label position coordinates by relying on the patented algorithm with high angular resolution, which can give full play to the advantages of 5G network with high speed, low delay and large link, thus improving network utilization efficiency and value-added value. The overall architecture of 5G+ Bluetooth AoA converged positioning system is shown in the following figure.
The 5G+ Bluetooth AoA positioning joint deployment completes the two grids of the communication network and the positioning network in one deployment. The positioning system fully reuses the power supply resources, transmission resources and later maintenance resources of the 5G base station, merges the construction, saves costs, and gives full play to the scale advantages of the operator's 5G indoor network construction. Transform from traditional voice and data service provider to indoor positioning service and Internet of Things service provider.
3) Description of application scenarios
Automated storage management, according to the positioning information of the goods, intelligent processing of three-dimensional storage, picking, packaging, transportation, sorting and other links of the goods, each link based on location services using automation equipment, robots, intelligent management system, quickly grasp the situation of warehousing and warehousing, greatly reducing costs and improving efficiency.
Intelligent warehouse management, based on the location information of personnel positioning and shelf storage, combined with AR technology, carries out intelligent processing of the operation links in the warehouse, such as warehousing, picking out and stocktaking. Taking picking as an example, the personnel are positioned in real time through positioning labels, and the picking path is presented on the intelligent device in combination with the picking path recommended by the WMS system. Guide the operator to the designated shelf storage for picking operations, avoid the wrong path, reduce the difficulty of picking, improve the efficiency of picking, and further optimize the storage layout of goods through the analysis of picking historical track data.
Electronic fence touch alarm, in the warehouse storage mobile watches, gold jewelry, leather bags and other luxury high-value goods area, through the setting of electronic fence combined with CV monitoring, when unauthorized personnel near the area, automatically trigger alarm information, improve the level of security supervision and control; Place positioning labels on high-value goods. When the operator completes the exit operation, the positioning labels need to be collected and reused to improve the utilization rate of labels and reduce the use cost.
In the goods temporary storage area of the large warehouse, there will be temporary stacking of goods, through the positioning label on the goods combined with RFID technology, you can quickly find the goods that need to be picked out of the warehouse, complete the warehouse operation or inventory operation, avoid looking for goods for too long, improve the efficiency of work.
Real-time tracking of delivery items, based on location services, master the behavior track of delivery personnel and delivery items, and provide positioning services for delivery personnel, quickly find the corresponding delivery items, and deliver to the recipient; At the same time, big data analysis can be carried out according to the track of personnel and items, which can present the workload of delivery personnel, observe the distribution of goods, adjust the distribution of delivery personnel, and make more efficient use of human resources. At the same time, it can meet the demands of personnel management through location attendance service.
Intelligent automatic distribution, automatic distribution of unmanned vehicles according to the distribution address to plan the route, the distribution robot according to the positioning navigation information to the designated location distribution, unmanned delivery, positioning system can carry out real-time tracking and viewing of the route trajectory of unmanned vehicles, and can provide the route track history back.
5G+ Bluetooth AoA high-precision positioning technology meets the positioning needs of the logistics industry, and uses high-precision positioning to drive the management and optimization of personnel, vehicles and assets. Under the guarantee of 5G network's large bandwidth, the advantages of Bluetooth AoA positioning can be fully utilized: Terminal low cost, ultra-low power consumption, compatible with a large number of different types of terminals (including mobile phones/PDAs, etc.), convenient to enable positioning capabilities to a large number of devices. The 5G+ Bluetooth integrated positioning solution provides location services, supports intelligent logistics management, and greatly drives the rich and practical applications of personnel, materials and vehicles in the logistics industry for operational efficiency, management efficiency, and safety supervision, and drives the rich applications in the logistics industry. At the same time, communication and positioning integration coordination, all kinds of logistics terminals have 5G high-speed, large concurrent communication capabilities and high precision positioning, to meet the needs of intelligent logistics.
