Example Embodiment

[0020] A displacement sensing positioning system based on radio frequency identification technology, including a fixed station 2 communicating with a host computer 3. The fixed station 2 is equipped with a first microprocessor MCU, and the fixed station 2 is coaxial with a set of shielding layers with leakage windows. For radio frequency cable connection, a radio frequency communication device is installed in the mobile station 1, and the mobile station 1 communicates with the fixed station 2 through the radio frequency communication device and the leakage window of the coaxial radio frequency cable shielding layer in turn. The host computer 3 communicates with the first microprocessor MCU of the fixed station 2 through CAN bus or RS-485 bus or optical fiber or coaxial cable or twisted pair, such as figure 1 Shown.

[0021] Such as figure 1 As shown, the fixed station 2 is connected to a set of coaxial radio frequency cables through its communication interface. The shielding layer...

Abstract

The invention relates to a displacement sensing positioning system on the basis of a radio frequency identification technology and a positioning method thereof. The system comprises a fixed station communicated with an upper computer; a first microprocessor MCU (Microprogrammed Control Unit) is arranged in the fixed station; the fixed station is connected with a group of coaxial radio frequency cables; each reference step-length coaxial radio frequency cable is provided with a positioning area; a shielding layer of each cable in each positioning area has two states, namely opening a leakage window or keeping shielding; a radio frequency communication device is arranged in a mobile station; and the mobile station is in radio frequency communication with the fixed station sequentially by the radio frequency communication device and the leakage windows of the shielding layers of the coaxial radio frequency cables. According to the invention, leakage states of one group of coaxial radio frequency cables in each positioning area are combined and coded into position codes of the position of the positioning area; a positioning function of a card reader can be totally replaced; the installation of the card reader is totally avoided; the system is simplified; the installation workload and the post maintenance workload are reduced; and the stability of the system is improved.

Description

technical field [0001] The invention relates to the field of displacement sensing positioning, in particular to a displacement sensing positioning system based on radio frequency identification technology and a positioning method thereof. [0002] Background technique [0003] At present, most of the traditional position sensing systems are used on the positioning line, and radio frequency card readers are installed at each positioning point, and each card reader has a different identification code; radio frequency identification cards are installed on the mobile station, and each identification card There are also different ID codes. When the mobile station moves near the card reader in the positioning area, the communication between the identification card and the card reader is realized. According to the mutual identification between the card reader and the identification card, the identity and location information of the mobile station are determined, and the positionin...
