Automatic door system
An automatic door system is configured to allow a signal to unfailingly reach a smartphone or the like carried by a customer in various places. The automatic door system includes a BLE module configured such that, in a predetermined direction from a surface of a door, a signal that contains information based on which the BLE module can be identified transmitted from the BLE module reaches an area beyond a person sensing area covered by a sensor.
1. An automatic door system comprising:
a door configured to be driven by electric power and thereby open and close;
a switch configured to switch between an ON state and an OFF state, the ON state being a state in which the electric power is supplied to open or close the door, the OFF state being a state in which the electric power is not supplied; and
a transmitter that operates in a first state in which the transmitter is configured to transmit a signal when the switch is in the ON state and not to transmit the signal when the switch is in the OFF state, the signal containing identification information indicative of the transmitter, and
wherein the transmitter is configured to be selectively placed in the first state or a second state, the second state being a state in which the transmitter transmits or does not transmit the signal irrespective of whether the switch is in the ON state or the OFF state.
2. The automatic door system of claim 1 , further comprising:
a sensor,
the sensor being configured to sense a person who is about to pass through the door,
the door being configured to open and close in accordance with a result of sensing by the sensor,
the transmitter being configured such that, in a predetermined direction from a surface of the door on at least one side of the door, the signal transmitted from the transmitter reaches an area beyond a person sensing area covered by the sensor, the signal containing identification information indicative of the transmitter.
3. The automatic door system as set forth in claim 2 , wherein the transmitter is configured such that, in a direction normal to a center of the surface of the door on at least one side of the door, the signal transmitted from the transmitter reaches an area beyond the person sensing area covered by the sensor.
4. The automatic door system as set forth in claim 2 , comprising:
a door controller configured to control opening/closing of the door; and
a door engine configured to open and close the door in accordance with control by the door controller,
the transmitter being configured to receive electric power from the sensor, the door controller, the door engine, and/or a member included in the automatic door system.
5. The automatic door system as set forth in claim 2 , comprising:
a receiver configured to receive an acknowledgment signal that is sent, in response to the signal, by a mobile data terminal which has received the signal; and
a door controller configured to control opening/closing of the door in accordance with the acknowledgment signal.
6. The automatic door system as set forth in claim 5 , wherein:
the receiver is configured to receive identification information indicative of the mobile data terminal; and
the door controller is configured to control opening/closing of the door in accordance with the identification information indicative of the mobile data terminal.
