5G Internet of Things uwb chip positioning and ranging module centimeter-level precision technology is realized. The birth of 5G skills leads the change of all walks of life, makes up for indoor positioning technology, and will greatly promote the development of indoor positioning technology. UWB is a commonly used indoor positioning technology. Due to its high precision, high stability and low energy consumption, uwb chip positioning and ranging module is widely used in intelligent manufacturing, intelligent construction, elderly care, petrochemical and other industries.
Analysis on the advantages of indoor positioning technology of uwb chip location ranging module
1. 10cm high-precision indoor positioning
UWB is a high precision indoor positioning technology. Due to positioning algorithms and hardware devices, the accuracy of UWB positioning systems developed by different enterprises may vary slightly. For example, the positioning system of uwb chip positioning and ranging module adopts broadband narrow pulse communication technology (high time resolution, reduce positioning error), multi-source data integration (effectively improve the anti-interference ability of positioning system) and time series signal processing technology (extract the first path signal in the strong multi-path complex environment), which can realize the high-precision positioning of 10cm.
2. Short working time and low power consumption
The UWB positioning technology uses intermittent pulses to send data. The pulse duration is very short, generally between 0.20ns-1.5ns, with a vacancy duty factor, and the system power consumption can be very low. In high-speed communication, the system power consumption is only hundreds of μW and dozens of mW. The power of civilian UWB devices is generally about 1/100 of the power required by traditional mobile phones, and about 1/20 of the power required by Bluetooth devices. As a result, the battery life of UWB devices is a big advantage over traditional wireless devices.
3, strong anti-interference, small impact on other equipment
Because the uwb chip positioning and ranging module pulse is extremely narrow and the frequency band is extremely wide, its bandwidth is equivalent to 1000 TV channels or 30,000 FM broadcast channels, so the power density per unit bandwidth is quite low. The US FCC severely limits the transmitted power of UWBs, and their power density is even lower than general noise levels (for example, lower than laptop radiation). Therefore, the uwb chip positioning and ranging module positioning technology has little influence on other devices.
4. High capacity, many labels can work at the same time within 1S
UWB uses bandwidth in excess of 1GHz and up to several GHz, so the duration of each UWB signal is very short. More popular is that we can regard signal communication as vehicles of different widths, such as bicycles (UWB signal), cars (narrow-band signal), road width must (time resource), the narrower the vehicle, the more vehicles the road can accommodate, such as only bicycles on the road, only cars on the road, bicycle capacity will be greatly greater than cars. Therefore, the uwb chip positioning and ranging module system has a large capacity and can accommodate hundreds of positioning labels at the same time.
To sum up, one of the main reasons why indoor positioning can be quickly accepted by all walks of life is that there are many kinds of indoor positioning technologies. Different industries have different requirements for positioning accuracy, so the positioning technologies used are also different. As an indoor positioning technology analyzed from the aspects of positioning accuracy, security, anti-interference and power consumption, uwb chip positioning and ranging module is undoubtedly one of the ideal industrial indoor positioning technologies.
In the 5G era, high-precision indoor positioning technology and outdoor positioning GPS, Beidou and other satellite positioning tools have a large market share, so indoor positioning is indeed beyond the scope of GPS application. According to statistics, people spend 80 percent of their time indoors, so it's time for indoor positioning to work. In fact, indoor positioning technology has long been a "hot industry" in the eyes of many giants, among which common indoor positioning technology includes Bluetooth positioning technology, WiFi positioning technology, UWB positioning technology, Zigbee positioning technology, radio frequency technology, visual positioning and so on.
How much is the demand for indoor positioning technology of uwb chip location ranging module? More than 80% of customers hope to obtain the information of peripheral goods through mobile Internet when shopping; For the service needs of the masses, how to park in a large parking lot in an efficient way and find a parking space easily without the hassle? Where are the items you usually use in the supermarket? Where is the nearest restaurant? At the airport, accurately guide the user to go through the formalities, indicate the location of the toilet, etc. These are headaches that must be solved.
In what fields is indoor positioning technology applied?
Shopping centers, scenic spots, hotels, parking lots, hospitals, parks, conferences, railway station navigation, nursing home personnel positioning, smart city and other directional information have great demand for uwb chip positioning and ranging module.
1. In the elderly care scenario, real-time supervision can be completed in order to ensure the safety of the elderly. Railway stations need indoor map navigation, passenger flow monitoring and analysis.
2. In the underground parking lot, it can provide users with parking, positioning and navigation services to save time, improve the processing power of the parking lot, and improve users' parking experience.
3. The factory needs to complete intelligent storage processing, production process pursuit, active cargo handling and active target processing to reduce costs and increase power.
4. Hospitals need to pursue and locate care goals, medical equipment, doctors and other personnel and property in real time to improve the dynamics of service.
5. Logistics and manufacturing industries look to increase operational power by pursuing employees, fast calculations, and locating inventory.
6. Medical and first aid areas need to quickly locate the target of assistance indoors; Service robots, line patrol robots, reconnaissance robots in service industries, oil and gas, electric power and military industries need indoor positioning and navigation such as tunnels.
7. Complete orientation tour and exhibit introduction at tourist attractions, exhibition halls and airports. Indoor navigation skills are required for all of the above uses.
What technical changes will uwb chip location ranging module usher in for indoor positioning technology? The arrival of 5G leads the change of indoor positioning technology, because 5G can obtain the signal transmission between the mobile phone and the base station. For example, UWB indoor positioning technology can support TOF positioning and AOA positioning, and also make up the 1m~3m positioning accuracy gap of UWB indoor positioning technology. As a high-precision and stable indoor positioning technology, UWB is promoted by 5G. uwb chip positioning and ranging module can not only improve the precision of indoor positioning technology, but also promote the sustainable development of consumption level.
Therefore, the demand for the Internet of everything brought about by the 5G era will greatly promote the demand for indoor positioning technology. The 5G era will be an important opportunity for the Internet of Things based on indoor positioning technology to make a breakthrough in the battle of consumption.
