- the vacuum cleaner 11 when the vacuum cleaner 11 travels a predetermined distance based on the signal transmitted from the second transmitter 45 of the charger 12, the signal is transmitted from the first transmitter 24 again.
- the main body case 15 is not turned around the entire circumference and a signal is transmitted from the first transmission unit 24 at each turning angle, but the main body case 15 is set only at an angle located in the vicinity of the traveling direction including the traveling direction. You may make it transmit by turning. That is, when the electric vacuum cleaner 11 is caused to travel back to the charger 12, when the electric vacuum cleaner 11 has traveled once by receiving a signal transmitted from the second transmitter 45 of the charger 12, the travel is performed.
- the main body case 15 Since it is determined that the charger 12 exists on the direction side and the charger 12 does not exist on the opposite side or the like, the main body case 15 is swung only to the side where the charger 12 is determined to exist and the first case is turned. By transmitting a signal from the transmission unit 24, unnecessary signal transmission and traveling control (turning) of the main body case 15 can be omitted, and the battery 12 can be returned to the charger 12 in a shorter time.
- a plurality of first transmission units 24 and a plurality of first reception units 25 of the first embodiment are arranged in the main body case 15, and the first control unit 26 includes the first transmission unit 24.
- the first receiver 25 sequentially transmits and receives signals around the body case 15 in a plurality of directions.
- the first transmission unit 24 can transmit a signal from a position around the upper part of the main body case 15, that is, at a predetermined angle in the circumferential direction, for example, every 10 °.
- the first receiving unit 25 can receive signals at the periphery of the upper portion of the main body case 15, that is, at a position spaced apart by a predetermined angle in the circumferential direction.
- the first receiving unit 25 may receive signals from the entire circumference of the main body case 15. That is, the directivity D2 of the first receiving unit 25 has a wider range of directivity than the directivity D1 of the first transmitting unit 24. Therefore, the number of the arranged directing units D2 may be smaller than that of the first transmitting unit 24. Therefore, the reception table stored in the first control unit 26 is set so as to cover 360 ° for the plurality of first reception units 25 as a whole.
- the first control unit 26 transmits a signal including the first identification information from any of the first transmission units 24 (step 21), and is transmitted from the second transmission unit 45 of the charger 12 by the first reception unit 25. It is determined whether or not a signal including the second identification information is received (step 22). If it is determined in step 22 that the signal has been received, the first control unit 26 sends the signal to the reception table corresponding to the angle of the first transmission unit 24 that transmitted the signal with respect to the front of the vacuum cleaner 11. The fact that it has been received is recorded (step 23, reception recording), and the process proceeds to step 24. If the first control unit 26 determines in step 22 that no signal has been received, the process proceeds to step 24 as it is.
- the first control unit 26 causes the first transmission unit 24 that transmits a signal next to the first transmission unit 24 that transmitted the signal in step 21 to be adjacent to the first transmission unit 24 in the predetermined direction, for example, the clockwise direction. Switch to the transmitter 24 (step 24).
- the first control unit 26 has returned to the first transmission unit 24 that transmitted the signal first, or in other words, transmitted signals from all the first transmission units 24. It is determined whether or not (whether or not the first transmission unit 24 that transmits a signal makes one round) (step 25). If the first control unit 26 determines in step 25 that signals are not transmitted from all the first transmission units 24, the process returns to step 21. In step 25, if the first control unit 26 determines that signals have been transmitted from all the first transmission units 24, the process proceeds to step 8.
- a plurality of the first transmission units 24 and the first reception units 25 are arranged in the main body case 15, and the first control unit 26 is arranged around the main body case 15 by the first transmission unit 24 and the first reception unit 25.
- the signal when the vacuum cleaner 11 travels a predetermined distance based on the signal transmitted from the second transmitter 45 of the charger 12, the signal is transmitted from the first transmitter 24 again.
- the signal may be transmitted not only from all the first transmission units 24 but only from the first transmission unit 24 located in the vicinity of the traveling direction including the traveling direction. That is, when the electric vacuum cleaner 11 is caused to travel back to the charger 12, when the electric vacuum cleaner 11 has traveled once by receiving a signal transmitted from the second transmitter 45 of the charger 12, the travel is performed. Since it is determined that the charger 12 is present on the direction side and the charger 12 is not present on the opposite side, the signal is transmitted only from the first transmitter 24 located on the side where the charger 12 is determined to be present. Thus, unnecessary signal transmission and control can be omitted, and the battery 12 can be returned to the charger 12 in a shorter time.
- the output intensity of the signal transmitted from the first transmission unit 24 is reduced to suppress indirect reception of this signal by the second reception unit 44.
- the signal is received by the second reception unit 44. Even if the signal reception sensitivity is lowered, the same effect can be obtained.
- the reception sensitivity of the signal received by the first receiving unit 25 is reduced or the second transmitting unit 45 transmits the signal so that indirect reception by the first receiving unit 25 of the signal transmitted from the second transmitting unit 45 is suppressed. Even if the output intensity of the signal is reduced, the same effect can be obtained.
- the transmission units 24 and 45 and the reception units 25 and 44 may transmit and receive signals using wireless media such as ultrasonic waves and laser beams, for example, other than infrared rays.
- the vacuum cleaner 11 basically travels in the direction in which the signal from the second transmitter 45 is received.
- the traveling direction is a direction at a predetermined angle with respect to the reception direction. As long as the traveling direction has a predetermined relationship, the receiving direction and the traveling direction do not necessarily match.
- the present invention can also be applied to a self-propelled device configured as described above.
- a self-propelled device configured as described above.
- a vehicle equipped with an imaging means (camera) as a traveling body
- a user issues a command to the marker from a portable terminal or the like from outside, and the traveling body is guided to a predetermined position by the marker.
- It can also be used as a self-propelled device for indoor monitoring, such as for taking pictures of the camera.
- transmission control means transmission control section
- motor control means motor control section
- the signal including the first identification information is transmitted by the first transmission unit 24 of the vacuum cleaner 11 with the directivity D1 having a predetermined width, and this signal is transmitted to the second of the charger 12. Only when the signal is received by the receiver 44, the signal including the second identification information is transmitted from the second transmitter 45, so that the signal including the second identification information is constantly transmitted from the second transmitter 45. Thus, it is difficult to block other signals from the operation means (remote controller) received by the first receiver 25 by the signal transmitted from the second transmitter 45, for example. That is, signal interference to the vacuum cleaner 11 is unlikely to occur due to the signal transmitted from the second transmitter 45.
- the signal including the second identification information is received by the first receiving unit 25 having the directivity D2 wider than the directivity D1 of the first transmitting unit 24, the signal including the first identification information is transmitted.
- the first control unit 26 controls the driving of the motors 19 and 19 so that the main body case 15 travels based on the direction, so that the electric vacuum cleaner 11 can be reliably guided by the charger 12, for example, electric The vacuum cleaner 11 and the like can be reliably returned to the charger 12.
- the vacuum cleaner 11 travels in the direction in which the signal including the second identification information transmitted from the second transmission unit 25 is basically received, when returning to the charger 12 There is little useless travel, the capacity of the secondary battery 27 can be used more effectively, and the cleaning time can be taken longer.
- the output intensity of the first transmitting unit 24 is reduced to reduce the vacuum cleaner. It is possible to suppress the second receiver 44 from indirectly receiving the signal transmitted from the first transmitter 24 of 11 and to clarify the relative positional relationship between the vacuum cleaner 11 and the charger 12.
- the transmission units 24 and 45 and the reception units 25 and 44 can be configured with inexpensive parts and the directivities D1 and D4 of the transmission units 24 and 45 can be easily controlled.
- the first transmitter 24 can easily set the narrow directivity D1 using a simple configuration such as a slit.
- the vacuum cleaner 11 can be reliably returned to the charger 12 in order to charge the secondary battery 27 when cleaning is completed.
