Dynamic entrance controlling system and dynamic entrance controlling method

A dynamic entrance controlling method, comprising:

• a) sensing wirelessly a wireless signal emitting device (21) at a first time point by a first wireless signal receiving device (111) to obtain an ID information (ID1) of a target (2);
• b) sensing the wireless signal emitting device (21) at a second time point by a second wireless signal receiving device (112) to obtain the ID information (ID1) of the target (2),
• wherein one of the first wireless signal receiving device (111) and the second wireless signal receiving device (112) is set away from a position of a gate (4), and the other is set close to the position of the gate (14), and a moving direction of the target (2) is determined by comparing time order of the first time point and the second time point;
• c) reading a pre-stored image information (11) of the target (2) according to the ID information (ID1) when a host (13) determining the second time point later than the first time point;
• d) triggering an image capturing device (12) to capture a real-time image information (12) of the target (2) when the host (13) determining the second time point later than the first time point;
• e) comparing the pre-stored image information (11) and the real-time image information (12) to conduct identity recognition to the target (2);
• and
• wherein, the host (13) does not conduct the identity recognition to the target (2) when the first time point is later than the second time point.

A dynamic entrance controlling system (1) comprising:

• two signal receiving devices (11) respectively sensing wirelessly a wireless signal emitting device (21) at a first time point and a second time point so as to obtain ID information (ID1) of a target (2), wherein the ID information (ID1) is recorded in the wireless signal emitting device (21) and is related directly to the target (2);
• an image capturing device (12) receiving a trigger to capture a real-time image information (I2) of the target (2);
• and
• a host (13) electrically connected to the two wireless signal receiving devices (11) and the image capturing device (12), deciding to execute an identity recognition to the target (2) when determining the second time point is later than the first time point, wherein the identity recognition comprises reading a pre-stored image information (I1) of the target (2) according to the ID information (ID1), triggering the image capturing device to capture the real-time image information (I2), and comparing the pre-stored image information (I1) with the real-time image information (I2) to conduct an one to one identity recognition to the target (2);
• wherein, the host (13) does not conduct the identity recognition to the target (2) when the first time point is later than the second time point.
