Once the link is established, the master Bluetooth 404 in the operating button 400 device in the elevator will move from the slave button slave button in the landing button and the locator 300 device to the floor to which the passenger will be traveling soon. Ask for a list of information. In response, the slave Bluetooth 305 transmits a list of information on the floor to which the user wants to move, and the master Bluetooth 404 receiving the received information transmits the information to the main controller 403.

When the passenger of the current floor is finished, the main control unit 403 closes the door and reads the information list of the floor to be moved and transmits a control signal to the elevator control apparatus 700. The elevator then moves towards the floor to be moved.

Steps 705 to 707 are steps of searching for a new information electronic device 200 after arriving at the mobile floor. When the door is reached and the door is opened, the master Bluetooth 405 included in the operation button 400 device in the elevator performs an inquiry to know whether a new passenger is on board and the new information electronic device 200 If found, a Bluetooth link is established with the information electronic device 200. The operation button 400 device in the elevator has several master Bluetooth modules 405 similar to the master Bluetooth of the platform buttons and the locator device, and one master Bluetooth module has a predetermined number. Can be connected to the information electronic device 200. Therefore, even if more than a predetermined number of users use the elevator can accommodate this.

In addition, when the user gets off the elevator, the distance between the operation button 400 device in the elevator and the information electronic device 200 becomes far and the sensitivity of the received signal falls below a certain level, so that the main control unit 403 controls the corresponding information electronic device ( Disconnect the Bluetooth link.

Steps 708 to 711 determine whether the door is opened or closed by resetting and driving by the timer unit 401 and the monitoring unit 402. When the elevator moves and stops on the floor, the operating button 400 device in the elevator has a monitoring unit 402, which constantly monitors the number of users currently present in the elevator. This is done by examining the number of Bluetooth links that are currently connected. When there is no change in the number, the timer 401 is driven and the door is automatically closed when the timer 401 expires. If a change in the number of links occurs before the timer 401 expires, the timer 401 is reset and the door does not close automatically.

Step 712 is where the elevator departs. When the passenger's boarding on the current floor ends or the timer expires, the main controller 403 closes the door and reads the information list of the floor to be moved and transmits a control signal to the elevator control apparatus 700. The elevator then moves back towards the floor to be moved.

As described above, the present invention can reduce the inconvenience of the user by automatically controlling the operation of the elevator through the electronic device equipped with the Bluetooth Bluetooth device.

In addition, since it can be controlled through wireless communication, there are fewer physical presses of the button, which increases the life of the operation button and significantly reduces the risk of failure or accident.
