Description
Technical Field
The invention relates to the technical field of RFID (radio frequency identification devices), in particular to a positioning floor, a positioning system and a positioning method.
Background
RFID (Radio Frequency Identification) is a non-contact automatic Identification technology, and can identify a specific target and read and write related data through a Radio signal without establishing mechanical or optical contact between an Identification system and the specific target. Because the target can be quickly read and written and managed by tracking for a long time, the method is widely favored in the field of intelligent identification. Meanwhile, with the rapid development of the internet of things technology in China, the RFID technology as the internet of things support technology is considered to be one of information technologies with development prospects, and fig. 1 shows a typical RFID system structure.
In the application of RFID technology, location-based services are a very popular and important technology. Currently, the well-known positioning service is GPS (global positioning system), and also beidou positioning system of our country. Although the GPS technology is most mature and widely applied, the GPS technology has obvious defects, is poor in positioning precision and does not support indoor positioning. Therefore, more and more other wireless network technologies are beginning to enter the field of location services, such as Wi-Fi, RFID, ZigBee, Bluetooth, infrared and UWB ultra wide band technologies, etc. The RFID positioning technology has the most market acceptance and use scenes from the multi-dimensional conditions of positioning accuracy, market planning degree, actual positioning effect, confidentiality and the like of various technologies. The system has the characteristics of low power consumption, good multipath resistance effect, strong anti-interference capability, high safety, high positioning precision and the like, so that the system can be widely applied to important fields of assets, personnel positioning management, vehicle management, fire protection, public safety, inventory checking, personnel monitoring, lifesaving and the like.
Currently, the mature RFID technology applied to indoor personnel or object positioning is implemented by adopting a dual-frequency (125KHz low-frequency +2.4GHz active) trigger type scheme, but the technical scheme needs to perform a complex weak current construction stage, for example, when a ceiling type positioning antenna is adopted, a power line needs to be laid on a ceiling for a low-frequency activator and an interface needs to be reserved, if the number of positioning antennas is large, the number of used activators is also large, and the weak current construction is extremely time-consuming and labor-consuming; if adopt and bury formula location antenna, need carry out large tracts of land to the indoor ground and reform transform, the cement ground need cut and bury the antenna, ceramic tile, timber apron, prevent that all need to change the floor or reform transform the floor on static floor, these works all waste time and energy, and can all influence the degree of safety and the pleasing to the eye degree of self after reforming transform. In addition, when the ceiling type positioning antenna is adopted, the positioning antenna is installed on a ceiling, so that the signal radiation range is wide, the signal is refracted and interfered more, the signal overlapping or serial reading is easy to occur, and the positioning is not accurate.
