When the signal transmitter 1 is unlocked, the photosensitive sensor 2.7 senses the signal once, and the unlocking pin 2.6 resets.

[0051] Step 4: The automatic door 4 opens, allowing book buyers to leave the library.

[0052] The conditions for triggering a regulatory alert are as follows;

[0053] Condition 1: When a book with a signal transmitter 1 is brought near the edge of the library area, an alarm is triggered and the book purchaser is alerted. The surveillance footage of that time period is saved. If the person does not leave within the specified time, an alarm will be triggered.

[0054] Condition 2: Take the book with signal transmitter 1 and leave the library area, directly activate alarm 2.3, and directly save the surveillance footage 3 for that time period.

[0055] The conditions under which the automatic door opening / closing function for book buyers will not open are as follows:

[0056] Condition 1: When the person purchasing the books has not purchased any books, the signal transmitter 1 remains on the books and is close to the range of the intelligent controller 2 and the automatic door 4. The automatic door 4 does not open, and the monitoring footage of that time period is saved.

[0057] Condition 2: When a book purchaser pays for a book and the intelligent controller 2 detects that other signal transmitters 1 are near the automatic door 4, the automatic door 4 will not open and will remind the book purchaser to continue paying or for other book purchasers to leave the automatic door 4 within a certain range. The monitoring footage 3 for this period of time will be saved.
