Next, a description will be given of a control flowchart of various operations of the deadbolt electronic lock device according to the present invention configured as described above.

First, the control flow chart of normal alert operation will be described.

Figure 7 shows a control flow chart of the normal boundary operation of the dead bolt electronic locking device according to the present invention.

As can be seen in Figure 7, the deadbolt electronic locking device 200 is operated in a normal alert operating system to maintain the normal data while the red LED (284) is kept off (OFF) in the state of no alarm occurs When the alarm occurs, the red LED 284 is turned on and the alarm data is transmitted to release the alarm. Then, the red LED 284 remains OFF again to restore normal data. If the alarm is not cleared, the red LED 284 is returned to the ON state. Here, the alarming occurs at the opening of the door, at the open state of the lock device, at the tamper alarm, and at the open position of the manual key.

As shown in the control flowchart illustrated in FIG. 8, the deadbolt type electronic locking device 200 according to the present invention has the electromagnet locking device 240 turned on when the control board 250 is commanded to the open state with the start. By turning ON the primary coil of the solenoid 231, the dead bolt 234 is momentarily pulled with a strong force. At this time, if the lock close sensor 237 reacts with "yes", the red LED ( 284 is turned ON, and if the lock close sensor 237 responds with a "no", it returns to ON of the electromagnet lock 240, and the red LED 284. If the lock open sensor 236 responds with "yes" while it is turned on, the electromagnet lock device 240 is turned off, and the lock open sensor is locked. If 236 responds with "no", it returns to ON of the electromagnet lock device 240, and the electromagnet lock device 240 is turned off. The secondary coil of the solenoid 231 is turned on to maintain the dead bolt 234 drawn by the instantaneous strong force, and the primary coil of the solenoid 231 is turned off to open the door. By properly controlling the door to close the door, the electromagnet lock device 240 is turned on and the secondary coil of the solenoid 231 is turned off. At this time, the lock close sensor 237 is closed. If yes, the red LED 284 turns off with the electromagnet lock 240 off, and if the lock close sensor 237 responds with no. When the red LED 284 is turned on to transmit alarm data, when the red LED 284 is turned off, normal data is transmitted and the red LED is turned off. The door is kept locked.
