With the development of indoor positioning technology, high-precision, low-cost and widely used indoor positioning technology is an inevitable development trend. The comprehensive utilization of various positioning technologies and information will solve the application difficulties in various industries. Indoor positioning technology, as the continuation of positioning technology in indoor environment, makes up for the shortage of traditional positioning technology and professional UWB. At present, uwb locating manufacturers have been put into practical application in specific industries, achieved certain application results, and has a good application prospect.
Development status of indoor positioning technology of uwb location manufacturers
1. Indoor location service
Indoor location service has been applied to large indoor scenes such as supermarkets, airports, hotels, museums and convention centers. In the complex layout of large supermarkets, users can find interested goods; In large shopping malls, users can also find the stores and entertainment places they want to go to, and merchants can also carry out targeted advertising promotion and provide personalized marketing. In museums or exhibition centers, indoor positioning technology can also provide convenient positioning and navigation services.
2. Public safety
Indoor positioning technology of uwb location manufacturers plays an important role in emergency rescue, fire protection, security and law enforcement. When there is an emergency such as an earthquake or fire, the necessary condition for rescue is to quickly locate the personnel. Especially when the layout of the building changes due to an emergency, it is difficult to locate personnel quickly through experience. Indoor positioning technology can provide powerful technical support for rescue, better guarantee the safety of rescuers and trapped personnel, faster and effective rescue.
3. Personnel and goods management
Indoor positioning can provide indoor positioning monitoring services for students, patients, prisoners and other special groups. Specifically, to provide parents with information about their students' schooling; Provide login service for company employees; (I) Provide prisons with reports on prisoners' activities; Set up electronic fence for kindergartens to provide real-time monitoring. At the same time, uwb location manufacturers indoor positioning technology can also provide goods positioning services for warehousing, convenient goods anti-theft, sorting, transportation, and provide location records of the whole process.
4. Smart transportation
Indoor positioning technology combined with traditional positioning technology can provide indoor and outdoor seamless positioning and navigation services for the whole process of vehicle navigation from the road to the parking lot, and solve the problem of finding cars in large complex underground parking lots.
5. Big data analysis
uwb location manufacturers indoor positioning can record the user's activity track, big data analysis of these data, and the user's location and behavior and behind the interest and preference. Therefore, the mining and analysis of indoor location data has great commercial value and application prospects. For example, the analysis of consumer activities in shopping centers can analyze the frequency and stay time of consumers visiting a certain store, so as to obtain consumers' interest, preference and heat, which provides a powerful help for business analysis.
6. Social networking
Social network plays an important role in people's life and its status is the core of social network. In indoor environments, where about 80 percent of people's lives are spent, real and accurate locations can connect friends with activities.
Difficulties and development trends of indoor positioning. Although the accuracy of indoor positioning technology is constantly improving, it has not been promoted in all walks of life. The main difficulties are as follows:
1. The environment is complex
The layout of the indoor environment is complex and changeable, with numerous obstacles, including furniture, rooms and pedestrians. At the same time, there are many interference sources in the indoor environment. Interference sources such as lighting, temperature, and sound will affect the location to some extent.
2. Locating an unknown environment is difficult
At present, most indoor positioning technologies are based on a priori understanding of the indoor environment. Some positioning techniques also require the base station to be arranged in advance, but in practice there may be no environmental information, or the location of the base station is subject to interference and damage, such as earthquake and fire sites. Reducing dependence on the environment is also the difficulty of indoor positioning.
3. It is difficult to take into account positioning accuracy and cost
At present, the high precision indoor positioning technology of uwb location manufacturers requires expensive additional auxiliary equipment or a lot of manual processing, which greatly limits the popularization of the technology. Low-cost positioning technology needs to improve positioning accuracy. On the basis of providing high precision positioning, reducing the cost is also a direction of indoor positioning.
