I. Introduction
With the rapid development of science and technology, wireless communication technology has penetrated into all aspects of our lives. Among them, ultra-wideband (UWB) technology, as a new wireless communication technology, has been widely used in the field of positioning and ranging because of its high precision, high speed and low power consumption. This paper will deeply analyze the technical principle of UWB positioning chip and distance UWB communication chip, and discuss their advantages in practical application.
Second, UWB technology principle
Ultra-wideband (UWB) technology is a carrier-less communication technology, which realizes wireless communication by sending and receiving nanosecond pulse signals. UWB technology has the following advantages:
High resolution: The UWB pulse signal has a very high time resolution, which can accurately measure the signal arrival time, so as to achieve high-precision positioning and ranging.
Low interception rate: Because the power spectral density of UWB pulse signal is very low, it is difficult to be intercepted, which improves the communication security.
Anti-multipath interference: The UWB pulse signal has an extremely wide bandwidth, which can effectively suppress multipath interference and ensure communication stability.
Third, UWB positioning chip and ranging ultra-wideband communication chip
UWB positioning chip
UWB positioning chip adopts advanced signal processing technology and algorithm to realize accurate positioning of target object. It works as follows:
(1) Multiple UWB receivers are distributed in different locations to form a positioning network.
(2) The target object carries a UWB tag and continuously sends a pulse signal.
(3) After the UWB receiver receives the pulse signal sent by the label, the position of the target object is calculated by measuring the time difference between the arrival of the signal.
Ranging ultra wideband communication chip
The UWB communication chip is mainly used to measure the distance between two points. It works as follows:
(1) Two UWB devices are used as the sending end and the receiving end respectively.
(2) The sending end sends a nanosecond pulse signal and the receiving end receives the signal.
(3) Calculate the distance between two points by measuring the arrival time of the signal.
Fourth, the application advantages of UWB positioning chip and ranging ultra-wideband communication chip
High-precision positioning: The UWB positioning chip can achieve centimeter-level or even millimeter-level accurate positioning, which is suitable for scenarios requiring high-precision positioning, such as unmanned driving and robot navigation.
Strong anti-interference ability: Because the bandwidth of the UWB pulse signal is extremely wide, it can effectively suppress the interference of multipath interference and other wireless communication equipment, and ensure the stability of communication.
Low power consumption: UWB technology uses nanosecond pulse signal to transmit data, compared with traditional wireless communication technology, with lower power consumption, extending the service life of the device.
High security: Because the power spectral density of the UWB pulse signal is extremely low, it is difficult to be intercepted, which improves the communication security and is suitable for scenarios that require secure communication.
5. Practical application cases of UWB positioning chip and ranging ultra-wideband communication chip
Driverless: The UWB positioning chip can be used for accurate navigation and positioning of driverless vehicles. By placing multiple UWB receivers around the road, the driverless vehicle can receive the pulse signal from the tag in real time, calculate its own position and speed, and achieve accurate control.
Robot navigation: UWB positioning chip can be used for accurate navigation and positioning of robots. By installing UWB tags on the robot, the robot can continuously send pulse signals. After multiple UWB receivers receive the signal, the position and speed of the robot can be calculated by measuring the time difference between the arrival of the signal, and accurate control can be achieved.
Indoor positioning: Because UWB technology has the advantages of strong anti-multipath interference ability, it is suitable for indoor positioning scenes. For example, in a large shopping mall or warehouse, it is possible to accurately locate and navigate people by placing multiple UWB receivers.
Security monitoring: UWB ranging ultra-wideband communication chip can be used in the field of security monitoring. For example, in important places such as banks or museums, the distance between two points can be measured and monitored by arranging multiple UWB devices to improve security capabilities.
Smart home: UWB technology can be used in the smart home field. For example, home appliances can be interconnected and controlled by placing multiple UWB devices in the home. At the same time, the UWB ultra-wideband communication chip is used to realize the real-time monitoring and control of the home environment, and improve the convenience and comfort of life.
