Problems solved by technology

[0004] The health of the elderly is a hot spot in current scientific research. With the acceleration of population aging, the health care of the elderly has become more and more important. In recent years, researchers have found that the walking speed of the elderly is closely related to their health. Therefore, the elderly The precise measurement of human walking speed will become more and more important. However, the relevant research on the measurement of human walking speed in my country is basically in a blank state, and no research has given a complete speed measurement method.

Embodiment 1

[0063] Such as figure 1 As shown, the system consists of a radio frequency identification tag, a radio frequency identification reader (microwave antenna) and a data center. The radio frequency identification tag stores identification information, and the radio frequency identification reader reads the identification information of the radio frequency identification tag through the radio frequency identification method. It is sent to the data center through the data line, and the data center displays and records the data.

[0064] Such as figure 2 As shown, the radio frequency identification reader is connected to the radio frequency identification tag through radio frequency, the radio frequency identification reader is connected to the data center through the data line, the radio frequency identification reader is connected to the microwave antenna, and the radio frequency identification tag is connected to the reader through the built-in transmitting antenna connected. P...

Abstract

The invention discloses a speed measurement system based on an ultrahigh frequency radio frequency identification label and a measurement method. The measurement system comprises a radio frequency identification label, a first antenna, a second antenna, a radio frequency identification reader and a data center. The first antenna and the second antenna are connected to the radio frequency identification reader respectively. The radio frequency identification reader receives signals emitted by the radio frequency identification label through the first antenna and the second antenna respectively and sends to the data center respectively. The method in the invention is based on an ultrahigh frequency RFID technology. A Lagrange interpolation method is used to expand a data source. Through a maximum value time difference method of Gaussian fitting between partitions and kalman filter combination and a correlation time difference method of a Phat processor and SCOT weighting, data read by a reader is processed so that accurate measurement of a walking speed is realized. By using the system and the method, an error can be effectively reduced and precision is increased, and a large calculated amount is not needed. The ultrahigh frequency RFID label possesses advantages that the size is small; a price is low; a reading distance is long and so on. The system and the method can be made into a sensor which can be worn on an elder so as to carry out accurate measurement of the walking speed.

Description

technical field [0001] The invention relates to a speed measurement system and a measurement method based on an ultra-high frequency radio frequency identification tag, and belongs to the technical field of reading and identification of radio frequency identification tags. Background technique [0002] Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology. Each RFID tag has a unique identification (ID) information, and the RFID reader reads the ID of the RFID tag through radio frequency. information. This technology has the advantages of high recognition accuracy, strong anti-interference ability, long service life, etc., and the passive electronic tags used are low in cost and easy to install, and have been widely used in various fields. [0003] Interpolation, fitting, filtering, and cross-correlation are all commonly used data processing methods. The interpolation function is a function of interpolating continuous data on ...
