A positioning floor, positioning system and positioning method

Abstract

The invention relates to the technical field of RFID (Radio Frequency Identification), in particular to a positioning floor, a positioning system and a positioning method. The positioning floor comprises a floor and a positioning antenna packaged on the floor. The positioning antenna is connected with a signal source, and transmits a low-frequency pulse signal to form a low-frequency activation trigger region. The positioning method provided by the invention comprises the following steps of: presetting the positioning antenna in the low-frequency trigger positioning technology in an anti-static floor, that is, directly using the floor as the positioning antenna, and adjusting the identification range of the positioning antenna by adjusting the number of the splicing floor to control the accuracy of the positioning range. The low-frequency signal is more concentrated and less divergent since the mounting position of the anti-static floor is closer to a positioned tag, and the material characteristics of the anti-static floor can filter the signal of the part of the positioning antenna, therefore, the positioning is more accurate.

Description

technical field [0001] The invention relates to the field of RFID technology, in particular to a positioning floor, a positioning system and a positioning method. Background technique [0002] RFID (Radio Frequency Identification) is a non-contact automatic identification technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. Because it can read and write quickly and track management goals for a long time, it is widely favored in the field of intelligent identification. At the same time, with the rapid development of the Internet of Things technology in our country, RFID technology as the supporting technology of the Internet of Things is considered to be one of the promising information technologies, such as figure 1 A typical RFID system structure is shown. [0003] In the application of RFID technology, positioning servi...

Problems solved by technology

[0004] At present, the relatively mature RFID technology applied to indoor personnel or object positioning adopts dual-frequency (125KHz low-frequency + 2.4GHz active) trigger scheme to realize, but this technical scheme needs to carry out complicated weak current construction stage, for example, in the use of ceiling-mounted When positioning the antenna, it is necessary to lay the power line for the low-frequency activator on the ceiling and reserve the interface. If there are many positioning antennas and many activators are used, the weak current construction will be extremely time-consuming; To carry out large-scale renovation of the indoor floor, the concrete floor needs to be cut to embed the antenna, and the ceramic tile, wooden floor, and anti-static floor all need to replace or renovate the floor. These tasks are time-consuming and laborious, and will affect their own safety after the renovation Degree and beauty

In addition, when the ceiling-mounted positioning antenna is used, since the positioning antenna is installed on the ceiling, the signal radiation range is relatively wide, and it is subject to refraction and interference, and signal overlap or cross-reading is easy to occur, resulting in inaccurate positioning
