Abstract
A reading controller includes an open/closed state determination part that determines an open/closed state of a door of a load chamber of a vehicle, a tag information acquisition part that acquires tag information stored in a tag attached to a load, via a communication element that is installed in the load chamber and reads the tag, and a radio wave control part that controls a radio wave strength of radio waves emitted by the communication element for reading the tag to be a first radio wave strength when the open/closed state determination part determines that the door is in the closed state, and controls the radio wave strength to be a second radio wave strength, which is lower than the first radio wave strength, when the door is in the open state.
Claims6
A reading controller comprising:
- an open/closed state determination part that determines an open state or a closed state of a door of a load chamber of a vehicle;
- a tag information acquisition part that acquires tag information stored in a tag attached to a load, via a communication element that is installed in the load chamber and reads the tag;
- and
- a radio wave control part that controls radio wave strength of radio waves emitted by the communication element for reading the tag to be a first radio wave strength when the open/closed state determination part determines that the door is in the closed state, and controls the radio wave strength to be a second radio wave strength, which is smaller than the first radio wave strength and larger than 0, when the open/closed state determination part determines that the door is in the open state.
A reading control method that is executed by a reading controller, the method comprising the steps of:
- determining an open state or a closed state of a door of a load chamber of a vehicle;
- acquiring tag information stored in a tag attached to a load, via a communication element that is installed in the load chamber and reads the tag;
- and
- controlling radio wave strength of radio waves emitted by the communication element for reading the tag to be a first radio wave strength when the door is determined to be in a closed state and controlling the radio wave strength to be a second radio wave strength, which is smaller than the first radio wave strength and larger than 0, when the door is determined to be in the open state.
