The invention provides an RFID-based target positioning and trajectory analysis method. The method specifically comprises the following steps: S1, constructing geographical coordinate information of a reader-writer; s2, constructing a mapping relation between the radio frequency power value sequence of the reader-writer and the spatial geographic information of the reading area; s3, continuously and dynamically adjusting the radio frequency power of the reader-writer according to a preset strategy, and identifying and reporting the label information carried by the target in the corresponding reading area in real time; s4, the background service module carries out union, intersection and complementation real-time calculation on the data in a certain moment interval, and position information of the target label at the corresponding moment is determined; and S5, performing time sequence calculation on the position information of the target in a certain time window by the background service module, and determining the track information of the target label in the corresponding time. According to the invention, high-precision target positioning and high-real-time trajectory analysis can be completed by using fewer RFID readers.

The invention relates to a hand rehabilitation training and signal acquisition device integrated with a piezoelectric spring. The hand rehabilitation training and signal acquisition device comprises a wrist strap, a data acquisition unit, the piezoelectric spring, a finger elastic strap and a wireless communication unit, the data acquisition unit is fixed on the wrist strap, one end of the piezoelectric spring is mounted on the wrist strap, and the other end is connected with the finger elastic strap; the piezoelectric spring comprises a piezoelectric fiber and an elastic layer, the piezoelectric fiber is of a spiral structure, the elastic layer is packaged on the outer side of the piezoelectric fiber in the axial direction of the spiral structure, the piezoelectric fiber is electrically connected with the data acquisition unit, and the data acquisition unit converts charge changes of the piezoelectric spring into electric signals and transmits the electric signals to a terminal through the wireless communication unit. Compared with the prior art, the piezoelectric fiber spiral structure is adopted, the elastic layer is used for packaging, elastic supporting and signal collecting are integrated, real-time, objective and quantitative monitoring of hand rehabilitation training data can be achieved, and data support is provided for rehabilitation evaluation individuation and treatment remote.
