Trace positioning system and trace positioning method based on radio frequency tag

Abstract

The invention belongs to the technical field of wireless communication and particularly relates to a trace positioning system and a trace positioning method based on a radio frequency tag. The trace positioning system comprises the radio frequency tag, a radio frequency identifier, an information processors and a background control center, wherein the radio frequency tag is worn on a monitored object and is used for transmitting a radio frequency signal and tag information to the radio frequency identifier and positioning the monitored object in real time; the radio frequency identifier is used for receiving the radio frequency signal and the tag information, calculating distance information of the radio frequency tag and the radio frequency identifier according to an RSSI (Received Signal Strength Indication) value of the radio frequency signal, and transmitting the distance information and the tag information to the information processor; the information processor is used for calculating position coordinates of the radio frequency tag according to the distance information and the tag information; the background control center is used for establishing a monitoring map, displaying the position coordinates of the radio frequency tag on the monitoring map, and describing the motion trace of the monitored object according to the position coordinates of the radio frequency tag. The trace positioning system and the trace positioning method disclosed by the invention have the advantages of simplicity in positioning, convenience for implementation and convenience for real-time tracking and positioning of the monitored object.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a track positioning system and method based on radio frequency tags. Background technique [0002] In recent years, with the vigorous advancement of prison administration work and the great improvement of human rights protection, the daily activities of prison inmates have become more and more abundant. They can participate in physical exercise activities, cultural and educational activities, and labor reform activities in prisons. That is to say, the scope of daily activities of these personnel has expanded, which has brought certain difficulties to prison administration supervision. Under the premise of advocating the "digital management" of prisons, the application of various wireless communication technologies and communication tools has brought great convenience to the supervision of prisons, greatly improved the efficiency of supervision, and also...
