The invention relates to a radio-frequency tracking, positioning and monitoring system, which comprises a receiver, an activator and an active terminal. The radio-frequency tracking, positioning and monitoring system is characterized in that: the system adopts the following steps to perform tracking, positioning and monitoring: 1, performing basic setting; 2, starting to monitor; 3, receiving the data information of a terminal by the receiver, and judging whether the information has corresponding archived records; 4, acquiring an access permission of personnel corresponding to the information, and judging whether the personnel has the access permission, and 5, displaying the position of the personnel on a map. Because the monitoring system adopts the radio frequency mode, the system has the characteristics of high identification efficiency, high identification speed, large data capacity, long service life, wide application range, dynamically changeable tag data, better safety, and dynamic real-time communication.
