Abstract

A substance detection system ( 1 A) includes a substance sensor ( 10 ), a distance sensor ( 11 ), and an information processor ( 20 ). The substance sensor ( 10 ) detects a substance ( 3 ) emitted from a generation source ( 2 ). The distance sensor ( 11 ) detects distance (L) between the generation source ( 2 ) and the substance sensor ( 10 ). The information processor ( 20 ) includes a determiner ( 21 ). The determiner ( 21 ) determines whether or not the distance (L) detected by the distance sensor ( 11 ) falls within a range from (L 1 ) to (L 2 ) where a detection result by the substance sensor ( 10 ) is determined to be valid.

First claim

1 . A substance detection system, comprising:
a substance sensor to detect a substance emitted from a detection target; a distance sensor to detect a distance between the detection target and the substance sensor; and a determiner to determine whether or not distance detected by the distance sensor falls within a range where a detection result by the substance sensor is determined to be valid.

2 . The substance detection system according to claim 1 , comprising:
a notifier to notify that a substance can be detected by the substance sensor when the determiner determines that distance detected by the distance sensor falls within the range.

3 . The substance detection system according to claim 2 , wherein the notifier notifies that a substance cannot be detected by the substance sensor when the determiner determines that distance detected by the distance sensor falls outside the range.

4 . The substance detection system according to claim 1 , comprising:
a controller to start detection of a substance by the substance sensor when the determiner determines that distance detected by the distance sensor falls within the range.

5 . The substance detection system according to claim 4 , wherein the controller suspends detection of a substance by the substance sensor when the determiner determines that distance detected by the distance sensor falls outside the range.

6 . The substance detection system according to claim 1 , comprising:
a range storage to store the range with respect to each of the detection targets, wherein the determiner performs determination by reading the range corresponding to the detection target from the range storage.

7 . The substance detection system according to claim 1 , comprising:
a detection result storage to store a detection result by the substance sensor and a detection result by the distance sensor in association with each other.

8 . A substance detection system, comprising:
a substance sensor to detect a substance emitted from a detection target; a distance sensor to detect a distance between the detection target and the substance sensor; and a first corrector to correct a detection result by the substance sensor, based on a detection result by the distance sensor.

9 . The substance detection system according to claim 1 , comprising:
an environment sensor to detect information about an ambient environment; and a second corrector to correct a detection result by the substance sensor, based on a detection result by the environment sensor.

10 . The substance detection system according to claim 1 , wherein the substance sensor and the distance sensor are integrated with each other.

11 . The substance detection system according to claim 10 , comprising:
a main body; and an adapter attachable and detachable to and from the main body, wherein the substance sensor and the distance sensor are installed in the adapter.

12 . The substance detection system according to claim 10 , wherein the substance sensor and the distance sensor are separable from each other.

13 . The substance detection system according to claim 9 , wherein the substance sensor, the distance sensor, and the environment sensor are integrated with one another.

14 . The substance detection system according to claim 13 , comprising:
a main body; and an adapter attachable and detachable to and from the main body, wherein the substance sensor, the distance sensor, and the environment sensor are installed in the adapter.

15 . The substance detection system according to claim 13 , wherein at least two of the substance sensor, the distance sensor, or the environment sensor are separable from each other.

16 . The substance detection system according to claim 8 , comprising:
an environment sensor to detect information about an ambient environment; and a second corrector to correct a detection result by the substance sensor, based on a detection result by the environment sensor.

17 . The substance detection system according to claim 16 , wherein the substance sensor, the distance sensor, and the environment sensor are integrated with one another.

18 . The substance detection system according to claim 17 , comprising:
a main body; and an adapter attachable and detachable to and from the main body, wherein the substance sensor, the distance sensor, and the environment sensor are installed in the adapter.

19 . The substance detection system according to claim 17 , wherein at least two of the substance sensor, the distance sensor, or the environment sensor are separable from each other.
