How uwb personnel positioning module technology works compared to other positioning, there is a demand and a market. Indoor positioning technology has been applied in more and more practical scenarios. Factories, coal mines, tunnels, prisons, public security law, petrochemical, nursing homes, etc., all need personnel positioning. Through the application of indoor positioning technology, can ensure the safety of personnel in the operating environment, help enterprises intelligent management, reduce costs, improve efficiency. So, what are the commonly used indoor techniques?
With the development of Internet of Things technology, the following three mainstream technologies can be seen on the market: RFID, Bluetooth and UWB(ultra-wideband) positioning.
Indoor positioning technology RFID:
The technology took off in China about five years ago, but it has largely fallen out of favor because of its proximity and antenna costs. RFID technology has encryption attributes, natural anti-counterfeiting. Combined with characteristics, similar characteristics can be made. ETC For payment scenes like cards, we can often see a white antenna box at the entrance of the vehicle channel. When the vehicle approaches, we can read the data in the card, deduct the account, and open the gate.
Bluetooth indoor positioning technology:
The technology took off in China about two years ago. As traditional Bluetooth evolves into low power Bluetooth. After (BLE), the signal transmitting current of the Bluetooth tag decreases to mA level and standby current uA level. The active former Bluetooth tech camp also makes the use of Bluetooth location very attractive. At present, mainstream intelligent terminals support Bluetooth protocol, but it is still in the development stage due to the limitation of positioning accuracy and power consumption.
Indoor positioning technology UWB:
UWB In fact, this is an old and new technology that began to be used for military positioning and has only become widely used in the enterprise B end in recent years. Indoor positioning technology Ultra wideband uwb personnel positioning module using the TOA method of accuracy is quite reliable. The delay is also very short, can be said to be short, can be said that the ultra wideband uwb personnel positioning module technology is the rich and handsome in the field of indoor positioning. The delay of radio signals transmitted by the speed of light is quite short, which requires strong computing power and algorithms to ensure accuracy, so the complexity of the system is also very high, and the sensor network often makes ordinary scenes impossible to climb.
Because RFID antenna size is relatively large, inconvenient deployment, also not beautiful, so many scenes on the market do not match. The Bluetooth location cost is low, the size of labels and sensors is small, and the deployment is convenient, which is suitable for scenarios with low requirements for location results. UWB is applicable to positioning scenarios that require high positioning results and high added value. The fact that these commonly used indoor positioning technologies have their own markets in different scenarios does not deny the existence of these technologies.
In summary, based on the analysis of common positioning technologies, enterprises of all walks of life can choose their own solutions according to the characteristics of application scenarios. Another is to try to integrate with existing platform services to make it easier to build positioned products that meet customer needs.
With the rapid development of 5G+ and the Internet of Things era, indoor positioning technology is becoming more and more known under the derivative of outdoor technology. Indoor positioning technology makes up for the deficiency of outdoor positioning. In reinforced concrete high-rise buildings, uwb personnel positioning module positioning technology has reached centimeter-level positioning. These precise indoor positioning technologies solve many industry difficulties in different scenarios.
People live and work indoors much longer than outdoors, so there is a strong demand for indoor positioning. So where does this need come from? From the point of view of safety, take the power plant as an example, which has many equipments and complex structure. The most important one is danger. There are a lot of jobs to be managed by outsourcing staff, some equipment requires a lot of experience to control, and some Meng Xin, who has worked in power plants for a year or two, are also prone to mistakes. That's when you need an indoor positioning system, who's where, what he's doing, an electronic fence in a certain area, no trespassing, an alarm, a beep. This can greatly reduce the occurrence of safety accidents.
From a business scenario, users want direct access to the store or the location of the product they want. In airports, hospitals, exhibition centers, large parking lots and other places to find the gate, hospital departments, booths, cars need to navigate positioning.
From the perspective of industrial enterprises, such as tunnels, buildings, etc., in order to ensure the safety of personnel, it is also necessary to use accurate positioning. Various requirements promote the development of indoor positioning technology. Especially in the past two years, it is very popular UWB under the promotion of government policies, uwb personnel positioning module indoor positioning technology is widely used in the underground coal mine, the establishment of coal mine safety system, to ensure the safe operation of underground personnel, reduce the occurrence of coal mine accidents.
How does uwb personnel positioning module indoor positioning technology work?
1. Indoor positioning technology should have the function of identity identification
Identification function is the basis of indoor positioning technology. By inputting unique location tag information, real-time identification and tracking can be done indoors.
2. Indoor positioning technology should have real-time positioning function
According to the principle of time synchronization, the indoor positioning technology needs to upload the location data in real time. The indoor positioning technology of uwb personnel positioning module can complete the indoor real-time location upload in a relatively short time.
3. Indoor positioning technology sets the fence function
When the base station is set up indoors, the electronic fence can be designed according to the working environment. Through the ranging function between devices, you can locate the alarm in real time.
4. Indoor positioning technology "traceable" function
The history of the personnel is also recorded, and it can be seen at a glance when and where they arrived. Can monitor the key personnel, the system in the key personnel pool is bad when the active alarm, so as to achieve safety.
Of course, indoor location technology is not that simple. In fact, for a good industry, the core content of uwb personnel positioning module indoor positioning technology is people-oriented, to ensure the safety of personnel, to provide security for the safe operation of equipment. No matter what technology is used to achieve positioning, it is inseparable from this core, and other industries are similar.
