System Overview
As people’s requirements for location services are getting higher and higher, the traditional WiFi location system appears to be inaccurate in certain scenarios and cannot meet the requirements for ultra-high precision. Based on the characteristics of 125KHz triggering in time and precise boundaries, Youpin Technology has recently launched the “125KHz high-precision trigger positioning system”. On the premise of inheriting all the advantages of the original WiFi positioning system, this system integrates the low frequency 125KHz activation function, which improves the positioning system of the superior frequency from the original 3-5 meters accuracy to 0.5-1 meters. The positioning accuracy is higher and the real-time performance is better. In practical applications, it can accurately judge the inside and outside of the door, do more accurate behavior analysis, and realize real-time positioning and monitoring and management of personnel and assets.
working principle
This set of “125KHz high-precision trigger positioning system” is composed of positioning tags (dual frequency), 125KHz exciter, A and background positioning engine. After the location tag is triggered by the low-frequency signal of the 125KHz exciter, the activator ID number is uploaded to the location engine, and the accurate location of the tag is immediately obtained. In areas where there is no activator deployment, using UHF’s high-precision wireless positioning algorithm, the accuracy of 3-5 meters can also be achieved.
System advantages
The 125KHz high-precision trigger positioning system combines the respective characteristics of 125KHz and 2.4GWiFi. The advantages are particularly obvious and the application prospects are broad:
High positioning accuracy: It can achieve a positioning accuracy of 1-3 meters, and a key area of 0.5-1 meters, which fully meets the needs of personnel asset positioning in various scenarios;
Accurate boundary: the highest positioning accuracy of 0.5~1 meters, can accurately judge the inside and outside of the door, and realize the access control function.
Positioning engine: A combination of multiple positioning algorithms, including triangulation, wireless fingerprint positioning, low-frequency trigger positioning, etc., combined with historical trajectory analysis and scene structure analysis to improve positioning accuracy and stability;
Strong stability: It can automatically judge the interference of the human body and the environment, automatically adjust the positioning parameters, and increase the positioning accuracy and stability;
Low system power consumption: The dual-frequency tag adopts ultra-low power consumption design, adopts activation and sleep modes, and saves electricity. It also supports USB charging or battery replacement;
Massive terminals: a single positioning engine can locate 2000 terminal devices at the same time within 1 second, adopting a distributed architecture, can support multiple positioning engines at the same time, and manage millions of terminal devices;
High cost performance: The exciter supports up to 6 antennas, which has a wider coverage area, reduces equipment density, and under the premise of high precision, the system cost is lower;
High scalability: While triggering the positioning, the system adopts the international standard IEEE802.11b/g/n protocol. The WiFi network conveniently realizes multiple functions such as video, voice, and positioning, and the network has super compatibility;
Simple construction: the exciter can work with power supply, and it is easy to install without other data cables; the AP locator can use the existing network wiring, and the AP can also be wirelessly connected, so the construction is simple and convenient.
Actual case: The system has been tested in many industries such as domestic high-end elderly care communities, hospitals, prisons, etc., and is fully capable of various complex environments;
Industry Application
Using 125KHz low-frequency activation and WiFi positioning technology combined mode, low-frequency activator and AP locator are deployed in the door and outside of the room, corridors, main entrances and exits, halls, etc., and the two technologies of low-frequency activation positioning and WiFi positioning can be used interactively, which can satisfy Various high, middle and low positioning accuracy requirements.
System core functions: entry and exit management, entry and exit judgment of personnel, vehicles, classified assets, valuables, warehousing items, and circulating assets; real-time positioning, real-time accurate positioning and tracking of personnel and assets or monitoring management.
Applicable industry:
The 125KHz high-precision trigger positioning system can be widely used in the high-precision positioning, tracking and management of personnel and assets in prisons, detention centers, coal mines, factories, hospitals, nursing homes, logistics, enterprises and institutions, party and government agencies and other industries.
