  In step 2, the entrance / exit management device 3 detects that the user has touched the electrode 4b by receiving the user ID via the electrode 4b. The determination unit 6 determines that the state of the user has changed from the state in contact with the electrode 4a to the state in contact with the electrode 4b, and contacts the door knob when the user tries to enter the management unit 7 Notify you that you are Upon receiving the notification of the user status, the management unit 7 controls the electronic lock controller 8d to unlock the key.

  In step 3, the entrance / exit management device 3 detects that the user has touched the electrode 4c by receiving the user's ID via the electrode 4c. The determination unit 6 determines that the state of the user has changed from the state in contact with the electrode 4b to the state in contact with the electrode 4c, and notifies the management unit 7 that the user has entered the room. Upon receiving the user entry notification, the management unit 7 stores the received user ID in the memory as a user in the room, and further determines the number of people in the current room stored in the memory. Read, increase by 1 person, and store in memory. If the user has entered the room for the first time, the lamp controller 8a and the air conditioning controller 8b are controlled to turn on the lamp / air conditioner. If there is a message for the user who has entered the room, the room monitor controller 8c is controlled to display the message.

  Next, the flow of processing when the user leaves the room will be described. FIG. 5 is a sequence diagram showing a flow of processing of the movement direction detection system in the present embodiment.

  In step 1, the entrance / exit management device 3 detects that the user has touched the electrode 4c by receiving the user ID via the electrode 4c. The determination unit 6 stores in the memory that the user is in contact with the electrode 4c.

  In step 2, the entrance / exit management device 3 detects that the user has touched the electrode 4b by receiving the user ID via the electrode 4b. The determination unit 6 determines that the state of the user has changed from the state in contact with the electrode 4c to the state in contact with the electrode 4b, and the user contacts the doorknob with respect to the management unit 7 in an attempt to leave the room. Notify you that you are Upon receiving the notification of the user status, the management unit 7 controls the electronic lock controller 8d to unlock the key.

  In step 3, the entrance / exit management device 3 detects that the user has touched the electrode 4a by receiving the user's ID via the electrode 4a. The determination unit 6 determines that the state of the user has changed from the state in contact with the electrode 4b to the state in contact with the electrode 4a, and notifies the management unit 7 that the user has left the room. Upon receiving the user exit notification, the management unit 7 deletes the received user ID from the memory, reads out the number of people currently in the room stored in the memory, decreases the number by one, and stores it in the memory. Remember me. If it is the last person to leave the room, the electric power controller 8a and the air conditioning controller 8b are controlled to turn off the electric power of the electric light / air conditioning.
