I. Introduction
With the rapid development of science and technology, Internet of Things (IoT) technology has been widely used in various industries, especially in the field of logistics and warehousing. As an important part of modern logistics warehousing, intelligent warehouse's operation efficiency and accuracy directly affect the competitiveness and cost of enterprises. Ultra-Wideband (UWB) distance measuring wireless module with its high precision, high anti-interference and low energy consumption characteristics, become an indispensable technical support in intelligent warehouse. This paper will discuss the application and advantages of UWB distance measuring wireless module in intelligent warehouse in detail.
Ii. Overview of UWB technology
Ultra-wideband (UWB) technology is a wireless communication technology that transmits data using narrow pulses ranging from nanoseconds to microseconds. Compared with traditional wireless communication technology, UWB technology has higher bandwidth, higher data transmission rate and lower power consumption. At the same time, because UWB signal adopts narrow pulse transmission, its signal spectrum is widely distributed, and it has strong anti-interference ability. In terms of distance measurement, UWB technology can achieve centimeter-level or even millimeter-level positioning accuracy, so it has a wide range of application prospects in intelligent warehouses and other occasions requiring high-precision positioning.
Third, the application of ultra-wideband UWB distance measurement wireless module in intelligent warehouse
Real-time cargo location and tracking
In intelligent warehouses, real-time positioning and tracking of goods is the key to improve operational efficiency and accuracy. By deploying an ultra-wideband UWB range-measuring wireless module, each cargo tag can be equipped with a UWB receiver and communicate wirelessly with the UWB base station in the warehouse. The base station receives the UWB signal sent by the cargo label, and calculates the position information of the cargo by using the principle of time difference or multipath effect. In this way, the warehouse management system can grasp the location information of the goods in real time, and achieve accurate tracking and fast searching of the goods.
Intelligent shelf management
Intelligent shelf is an important part of intelligent warehouse, through the integration of ultra-wideband UWB distance measurement wireless module, you can achieve real-time positioning and quantity statistics of goods on the shelf. When the goods are placed on the shelf, the UWB receiver on the shelf will receive the UWB signal sent by the goods label and upload the location information to the warehouse management system. The management system updates and statistics the goods on the shelves in real time based on the location information to ensure that the quantity of goods is consistent with the inventory record. In addition, when the goods are picked up, the UWB receiver on the shelf detects the departure of the goods and automatically updates the inventory record, improving the accuracy and efficiency of inventory management.
Intelligent forklift and robot navigation
In smart warehouses, automation equipment such as forklifts and robots are important tools to improve operational efficiency. By equipping these devices with UWB distance measuring wireless modules, autonomous navigation and accurate positioning of the devices can be achieved. The forklift and robot will continuously send UWB signals during the driving process and communicate with the UWB base station in the warehouse. The base station calculates the location and driving direction of the equipment according to the received signal, and updates it to the warehouse management system in real time. According to the location information of the device, the management system plans the optimal driving path for the device to ensure that the device can complete the task accurately and efficiently.
Goods in and out of storage management
In the intelligent warehouse, the management of goods in and out is an important link. Through the deployment of UWB distance measuring wireless module, the real-time monitoring and recording of goods in and out of storage can be realized. When the goods pass through the outlet, the UWB receiver installed in the outlet will receive the UWB signal sent by the goods label and upload it to the warehouse management system. The management system determines the status of goods in and out of the warehouse according to the received signal, and automatically updates the inventory record. In this way, warehouse managers can grasp the situation of goods in and out of the warehouse in real time to ensure the safety and accuracy of goods.
Warehouse safety management
UWB distance measuring wireless module can also be used for intelligent warehouse security management. By deploying UWB base stations and receivers in key areas of the warehouse, the movement of personnel and cargo can be monitored in real time. When people or goods enter unauthorized areas, the system automatically triggers an alarm and notifies management to deal with it. This can effectively prevent theft, misoperation and other security incidents, improve the security of the warehouse.
Fourth, the advantages of ultra-wideband UWB distance measurement wireless module
High precision positioning: UWB technology can achieve centimeter-level or even millimeter-level positioning accuracy to ensure accurate tracking and fast finding of goods.
High anti-interference: UWB signal adopts narrow pulse transmission, with strong anti-interference ability, to ensure that it can still work stably in complex environments.
Low power consumption: The low power consumption of UWB technology can extend the service life of equipment and reduce operating costs.
Real-time: UWB distance measurement wireless module can update the location information in real time and upload it to the warehouse management system to ensure that managers can grasp the status of goods in real time.
V. Conclusion
The wireless module of UWB distance measurement has a wide application prospect in intelligent warehouse. By integrating this technology, it can realize the real-time positioning and tracking of goods, intelligent shelf management, intelligent forklift and robot navigation, cargo management and warehouse security management. The realization of these functions can not only improve the operational efficiency and accuracy of the warehouse, but also reduce the operating cost and improve the security. Therefore, the wireless module of UWB distance measurement will become an indispensable technical support in the construction of intelligent warehouses in the future.
