ACTIVE THREE-DIMENSIONAL POSITIONING DEVICE AND CONTROL SYSTEM FOR FLOOR-CLEANING ROBOT THEREOF
First Claim
1. An active three-dimensional positioning device, comprising:
- a radio frequency (RF) receiver array, comprising a plurality of RF receivers, wherein each RF receiver is used for receiving a RF pulse;
a RF emitter, for emitting the RF pulse; and
a control circuit, coupled to the RF receivers,wherein the RF emitter emits the RF pulse when the control circuit outputs a transmission command to the RF emitter and the RF emitter receives the transmission command,wherein the control circuit calculates a relative position between the RF receiver array and the RF emitter according to positions of the RF receivers and receiving time when the RF receivers respectively receive the RF pulses.

Abstract
An active three-dimensional positioning device and a control system for floor-cleaning robot are provided in the present invention. The active three dimension positioning device includes a radio frequency (RF) receiver array, a radio frequency emitter and a control circuit. The RF receiver array includes a plurality of RF receivers for receiving a RF pulse. The RF emitter is used for emitting a RF pulse. The control circuit is coupled to the RF receivers. The control circuit transmits a transmission command to the RF emitter, after the RF emitter receives the enable RF signal, and the RF emitter emits the RF pulse. The control circuit calculates the position between the RF receiver array and the RF emitter according to the positions of the RF receivers and the time when each of the RF receivers receives the RF pulse.

8. A control system for floor-cleaning robot, comprising:
-
an RF receiver array, comprising a plurality of RF receivers, wherein each RF receiver is used for receiving an RF pulse; a floor-cleaning robot, comprising an RF emitter for emitting the RF pulse; and a control circuit, coupled to the RF receivers, wherein the RF emitter emits the RF pulse when the control circuit outputs a transmission command to the RF emitter and the RF emitter receives the transmission command, wherein the control circuit calculates a relative position between the RF receiver array and the floor-cleaning robot according to positions of the RF receiver and receiving time when the RF receivers respectively receive the RF pulses, wherein the control circuit continually records the relative position between the RF receiver array and the floor-cleaning robot to obtain a moving path of the floor-cleaning robot. - View Dependent Claims (9, 10)
