The invention provides an RFID -based parking lot vehicle positioning system, and discloses a parking position monitoring system. N activating units of the same activator are respectively arranged at the sidelines of N-1 adjacent parking positions; the N activating units of the same activator respectively transmit an identification code of the activator and address codes of the activating units in corresponding sub-periods in sequence; when a vehicle enters the parking position between the adjacent two activating units of the activator, wireless signals which are received by an electronic parking tag in a previous working period and have the highest field intensity which is greater than a preset value are the wireless signals which are transmitted by the adjacent two activating units in the adjacent two sub-periods, so that the electronic parking tag can analyze to obtain the identification code of the activator and the address codes of the adjacent two activating units, and a data server can accurately judge whether the parking position is occupied or not; the position and the state of the parking position of each parking lot can be acquired by a vehicle owner through a handheld terminal, so that the parking efficiency and the parking position utilization rate of the parking lot are improved. The invention further discloses the activator.
