At present, the mainstream positioning schemes in the market are Bluetooth indoor positioning and UWB indoor positioning. The former has a positioning accuracy of 3-5 meters, while the latter has a positioning accuracy of 30 centimeters, which is what we often call centimeter-level high-precision positioning. No matter what kind of indoor positioning system, it needs to be realized by positioning algorithm, positioning hardware products and positioning map. Positioning hardware products refer to the layout of Bluetooth gateway /UWB base station in the space to be positioned, and the configuration of Bluetooth tags (Bluetooth bracelet, Bluetooth badge, etc.). ) /UWB tag (UWB bracelet, UWB badge) for employees.
The total value of the chemical plant personnel positioning system based on Bluetooth is lower than that of the chemical plant personnel positioning system based on UWB, but the positioning accuracy is not as accurate as that of the UWB scheme. The cost of personnel positioning in chemical plants is actually related to the positioning scheme, positioning hardware products and positioning area you choose. I know SKYLAB and 95Power (Shenzhen Micro-Energy Information) who do personnel positioning systems in chemical plants. Regarding the measurement results, they set up two indoor positioning environments within the enterprise. Interested students can visit and study, hoping to help you.
