Preferably, the access control system also includes optoelectronic switch 300 and signal power source 301；Optoelectronic switch 300 is set
Between signal power source 301 and the mode of operation control end of card reader 200, for detecting whether someone is close to card reader 200；When
When someone is close to card reader 200, optoelectronic switch 300 is closed, the mode of operation control termination of signal power source 301 and card reader 200
Logical, card reader 200 works in normal mode of operation；When nobody is close to card reader 200, optoelectronic switch 300 disconnects, signal electricity
The mode of operation control end of source 301 and card reader 200 disconnects, and card reader 200 works in standby mode.
It should be noted that in the present embodiment, optoelectronic switch 300 is arranged in card reader 200, as someone close to card reader
When 200, illustrate that possible someone will swipe the card and enter, now, the normal work of card reader 200；When nobody is close to card reader 200,
Illustrate that nobody want and swipe the card to enter, now, card reader 200 makes it work in standby mode without continuing to expend excessive electric energy, treats
Under machine pattern, card reader 200 does not work substantially in addition to sending a notification line signal to the timing of main control chip 101, each electronics
Component is also substantially at power-off or resting state, and whole card reader 200 works in the state of an extremely low power dissipation, can be with maximum limit
The saving electric energy of degree.
More specifically, main control chip 101 be additionally operable to judge the power supply output end of controller power source 106 output voltage whether
Less than default low pressure threshold, or more than default HVT high voltage threshold.
Default low pressure threshold is less than when the output voltage of the power supply output end of controller power source 106 or more than default height
During pressure threshold value, main control chip 101 sends an alert notice to alarm 108, notifies that alarm 108 is alarmed.
