- FMCW Frequency Modulated Continuous Wave
- the door opening/closing control section may change the opening/closing timing of the door according to the moving direction and the moving speed of the object.
- the opening and closing operation of the door can be performed at appropriate timing according to the moving direction and moving speed.
- the door opening/closing control section may vary the opening/closing width of the door according to the position of the target.
- the door can be opened and closed with an appropriate opening/closing width according to the position of the target.
- the door opens and closes vertically, and the door opening/closing control section adjusts the opening/closing of the door according to the height of the object as the position of the object.
- the width can be different.
- the door can be opened and closed with an appropriate opening and closing width according to the height of the object.
- a number calculation unit that calculates the number of objects simultaneously detected by the sensor and the movement direction calculated by the movement direction calculation unit are used to enter through the door.
- a passing object that determines whether it is the object or the object that has gone out of the door, and outputs the number of the objects that have entered through the door and the number of objects that have gone out of the door. and a number output unit.
- various management such as management of the number of users can be performed using the number of objects output from the passing object number output unit.
- a door opening/closing control device includes a number calculation unit that calculates the number of objects detected by the sensor, and the door opening/closing control unit calculates the opening/closing width of the door according to the number of objects. can be different.
- the door can be opened and closed with an appropriate opening/closing width according to the number of objects.
- the door opening/closing control unit controls the opening of the door when the moving direction of the object is a moving direction in which the object does not approach the door. You can stop.
