With the continuous development of modern science and technology, indoor positioning technology has attracted more and more attention. In many scenarios, especially in large shopping malls, hospitals, office buildings and other places with large traffic, how to accurately locate and follow identity has become an urgent technical problem to be solved. Following location modules based on ultra-wideband (UWB) technology are favored by the market because of their high accuracy and practicality.
1. Advantages of UWB technology
Ultra-wideband technology is a kind of wireless communication technology, which is characterized by high transmission rate, strong anti-interference ability, penetrating walls and obstacles. UWB is a low-power, high-precision positioning technology that works indoors, outdoors and in harsh environments.
The advantages and disadvantages of UWB following positioning module in indoor scenes mainly lie in the following two points:
1. High positioning accuracy
UWB technology can calculate and track the position of the object through the time difference of signal transmission to achieve high precision positioning. In the actual test, the positioning error of the UWB positioning system is less than 10 cm, which is much higher than other indoor positioning technologies. This high-precision positioning can make the application of indoor positioning more rich and practical, such as personnel management, material tracking and so on.
2. Good following ability
When tracking objects or people indoors, UWB technology can realize the following function, that is, update its location information in real time as the movement of the object being followed. The following performance makes UWB tracking module have high application value in material tracking and personnel management.
Second, the basic principle of UWB following positioning module
As mentioned above, UWB technology mainly realizes the positioning and following function by calculating the signal transmission time difference. The UWB tracking module is mainly composed of tag and base station. The tag is the item or person being followed, and the base station is the device that receives the tag signal.
The label sends out a short pulse signal, the base station receives and calculates the time difference of the signal transmission, and then calculates the position information of the label. The location of the tag will change as it moves, and the base station can receive real-time location information for update. In this way, the base station can follow the movement of the tag and update its position information in real time to achieve the following and positioning functions.
3. Application scenarios of the UWB tracking module
1. Material management
UWB tracking module can track and manage materials. For example, in a large warehouse, the UWB label is used to mark the items, and the signal sent by the label is received by the base station, so that the location and quantity of the items can be understood, and the automation and precision of material management can be realized.
2. People management
In large shopping malls, office buildings, pavilions and other places with large traffic, the UWB tracking module can be used to locate and manage employees. For some scenarios that require dynamic employee management, such as the need to control the movement trajectory of employees during the epidemic, the UWB tracking module can monitor the location and actions of employees in real time, respond to emergency situations in a timely manner, and improve safety and management efficiency.
3. Indoor navigation
For some large shopping malls, hospitals and other huge buildings, whether residents or patients can easily find the area they need has always been a problem. Through UWB tracking module, these users can be provided with positioning services and indoor navigation, so that they can find the area they need more easily and improve user experience.
Fourth, market prospects
At present, UWB technology is widely used in many fields, especially in mobile phones, laptops and other devices. The popularity of UWB is also gradually increasing.
With the continuous improvement of science and technology, UWB gradually matures with positioning technology, and its market share is also gradually increasing. According to data from market research institutions, the global indoor positioning market will reach 10 billion US dollars in 2023, and the market will continue to grow in the future. With the continuous expansion of application scenarios, UWB will have a broader market prospect in the future.
V. Summary
UWB tracking module can improve the positioning accuracy and realize high precision position following. It has important application value in material management, personnel management, indoor navigation and other fields. Through UWB technology, the automation and precision of positioning and following can be achieved, improving management efficiency and security. In the future, the application prospect of UWB tracking positioning technology is very broad, and the market share is also gradually increasing.
