2.3. Operating principle of the system
a) Turn on the power and the system will enter into working state after 3 seconds.
b) When the card reader reads the valid card, the peak-mincer will make a pleasant sound, indicating to pedestrians that
the card has been read successfully. At the same time, it will judge and process the information read from the card, and
send an application for approval signal to the main control board.
c) The main control board receives the signals from the card reader and infrared sensor, and after comprehensive
processing, sends effective control signals to the direction indicator and motor, so that the direction indicator sign turns
into the green arrow pass sign. At the same time, the turnstile sends the setting voice, the main control board controls the
motor operation, and the gate is opened to allow pedestrians to pass.
d) After the pedestrian passes through the channel according to the direction indicator, the infrared sensor senses the
whole process of the pedestrian passing through the channel and continuously sends signals to the main control panel until
the pedestrian has passed through the channel completely;
e) If a pedestrian forgets to read his card or reads an invalid card and enters the channel, the system will forbid the
pedestrian to pass through and issue a voice alarm. The alarm will not be lifted until the pedestrian exits the channel.
Rereading a valid chi square allows passage.
