Abstract

An object of the invention is to provide a new defect detection technique using an autonomously movable apparatus. In order to accomplish the object, the invention provides a detection system (10) including a drive control unit (15) that controls a driving unit (12) causing a base unit (11) to travel in a case where a predetermined detection target is detected on the basis of information collected by a sensor unit (13) installed in the base unit (11), and a second detection unit (16) that detects a predetermined defect on the basis of the information collected by the sensor unit (13).

Claims

1. A detection system comprising:

a drive control unit that controls traveling of a base member in a case where a predetermined detection target is detected on the basis of information collected by a sensor unit installed in the base member; and

a second detection unit that detects a predetermined defect on the basis of the information collected by the sensor unit.

2. The detection system according to claim 1, further comprising:

a first detection unit that detects a predetermined detection target on the basis of the information collected by the sensor unit installed in the base member;

the base member;

a driving unit that causes the base member to travel; and

the sensor unit.

3. The detection system according to claim 2,

wherein in a case where the first detection unit detects the detection target, the drive control unit causes the base member to travel at a speed lower than in a case where the first detection unit detects no detection target.

4. The detection system according to claim 3,

wherein in a case where the first detection unit detects the detection target, the drive control unit controls the driving unit to cause the base member to travel at a second speed lower than a first speed at which the base member is traveling or to cause the base member to stop traveling.

5. The detection system according to claim 4,

wherein the driving control unit controls the driving unit to cause the base member travel to travel at the first speed at a predetermined timing after the driving control unit controls the driving unit to cause the base member to travel at the second speed or to cause the base member to stop traveling.

6. The detection system according to claim 5,

wherein the predetermined timing is:

a timing at which a predetermined period of time has passed from a timing at which control is performed to cause the base member to travel at the second speed or to cause the base member to stop traveling;

a timing at which a predetermined amount of data is collected by the sensor unit during traveling of the base member at the second speed or during stopping of the base member;

or a timing at which detection processing by the second detection unit is ended.

7. The detection system according to claim 2,

wherein in a case where the first detection unit detects the detection target, the second detection unit starts processing of detecting the predetermined defect.

8. The detection system according to claim 2,

wherein the sensor unit has a first mode and a second mode having lower accuracy in information collection than the first mode, the sensor unit transitioning to the first mode in a case where the first detection unit detects the detection target.

9. The detection system according to claim 1,

wherein the base member travels inside piping, and

wherein the second detection unit detects a defect in the piping.

10. A detection method executed by a computer, the method comprising:

a drive control step of controlling traveling of a base member in a case where a predetermined detection target is detected on the basis of information collected by a sensor unit installed in the base member, and

second detection step of detecting a predetermined defect on the basis of the information collected by the sensor unit.

11. A non-transitory storage medium storing a program causing a computer to function as:

a drive control unit that controls traveling of a base member in a case where a predetermined detection target is detected on the basis of information collected by a sensor unit installed in the base member; and

a second detection unit that detects a predetermined defect on the basis of the information collected by the sensor unit.
