What are the supporting hardware products in the personnel positioning scheme?

The system is generally composed of host, transmission interface, substation, identification card, power supply box, cable, junction box, lightning arrester and other necessary equipment. Central station hardware generally includes transmission interface, host, printer, UPS power supply, projector or TV wall, network switch, server, firewall and supporting equipment, etc.

UWB indoor positioning-related hardware, such as UWB base station, UWB label; or Bluetooth positioning-related hardware, such as Bluetooth gateway, ibeacon, Bluetooth positioning bracelet, Bluetooth positioning card, etc.

UWB positioning is mainly used for indoor high-precision positioning, which is used to obtain the location information of people or objects within a certain spatial range.

Mobile phones generally have both, GPS positioning is slow and the accuracy is not enough; A-GPS requires traffic and is accurate and fast.

and the number of people/objects that need to be positioned to determine the indoor positioning hardware products. For example, SKYLAB/95Power is a professional indoor positioning solution provider. With mature scheme applications, you can specifically describe the site personnel positioning project you need. For example, after the area and number of personnel are determined, it is easy to quote.

The total value of the Bluetooth-based chemical plant personnel positioning system is relatively lower than that of the UWB-based chemical plant personnel positioning system, but relatively, the positioning accuracy is not as accurate as that of the UWB scheme. The cost of positioning chemical plant personnel is actually related to the positioning scheme you choose, the positioning hardware products and the positioning area range.

What is the principle of indoor positioning technology to achieve precise positioning?

1. Neighboring information method: Use the limited range of signal action to determine whether the point to be measured is near a reference point. This method can only provide general positioning information. Scene divisionAnalysis method: Measure the intensity of the received signal and compare it with the signal strength at the position where the database is realized.

2. Bluetooth positioning: Bluetooth positioning is based on the positioning principle of RSSI (Received Signal Strength Indicator).

3. The principle of Hangfei Optoelectronic personnel positioning system is to use this system to install multiple wireless Bluetooth beacons on site as a timed basic network facility to broadcast positioning signals regularly to form a wireless positioning environment.

4. The principle of indoor positioning. Simply put, Beacon is a small information base station, which can be applied to indoor navigation, mobile payment, in-store shopping guide, flow analysis, item tracking and other activities related to indoor mobility.

Which Bluetooth personnel positioning system is better?

1. The dynamic control system of Sikale Internet of Things personnel can be applied in detention centers, prisons and other places. It has successfully landed in 11 prisons and has rich industry experience.

2. power indoor positioning hardware has more applications under the line. 95power mainly makes indoor positioning underlying hardware and positioning algorithms, which are integrated into the indoor positioning system. 95power indoor positioning hardware includes Bluetooth positioning and UWB positioning hardware.

3. The principle of Hangfei Optoelectronic personnel positioning system is to use this system to install multiple wireless Bluetooth beacons on site as a timed basic network facility to broadcast positioning signals regularly to form a wireless positioning environment.

4. At present, there are more and more SKYLAB Bluetooth personnel positioning solutions, and the application industry field is also getting wider and wider.
