Abstract

An olfactory system (300) capable of detecting a threat includes: a detection unit (100) including an IMS sensor (110) that outputs IMS data (115) relating to chemical substances included in fluid at a sampling point; a local memory (41) storing a library (49) including a specifying pattern (48) generated when a specified chemical substance was detected by the IMS sensor (110); and a matching unit (42) that routinely compares and matches the IMS data (115) and the specifying pattern (48) for monitoring purposes included in the library (49).

Claims

1. An apparatus comprising:

a detection unit acquiring chemical substance-related information relating to a chemical substance included in a fluid at a sampling point using a spectrometric sensor;

a communication unit that communicates wirelessly or via wires with an outside device;

a local memory storing a threat detection library including a specifying pattern generated when a specified chemical substance that is a cause of a threat was detected by the spectrometric sensor; and

a processor that includes a matching process and an outputting process and executes, in parallel or according to time division, the matching process and the outputting process,

wherein the matching process routinely compares chemical substance-related information obtained by the detection unit and a specifying pattern for monitoring purposes included in the threat detection library, and outputs match information when the obtained chemical substance-related information and the specifying pattern for monitoring purposes match, and

wherein the outputting process determines that an event relating to an odor has occurred based on a change in a chemical constituent or a change in concentration of detected chemical substances included in the obtained chemical substance-related information and outputs an occurrence of an event and an occurrence cause of the event, the outputting process including transferring, via the communication unit, the chemical substance-related information to the outside device and obtaining the occurrence cause of the event that includes chemical substances estimated from the chemical substance-related information and/or a cause of outputting of the estimated chemical substances.

2. The apparatus according to claim 1,

wherein the processor includes a function that acquires a specifying pattern of a chemical substance that poses a threat based on the occurrence cause of the event via the communication unit and updates the threat detection library in the local memory using the acquired specifying pattern.

3. The apparatus according to claim 1,

further comprising a unit that acquires event appended information including images and/or sound around the apparatus,

and the processor includes a function that interprets a state based on the images and/or sound included in the event appended information, acquires, via the communication unit, a specifying pattern including elements of an odor that poses a threat in the interpreted state, and updates the threat detection library in the local memory using the acquired specifying pattern.

4. The apparatus according to claim 1,

further comprising a sample storing unit operable when the occurrence cause of the event is not established, to seal the fluid at the sampling point in a storage capsule.

9. The apparatus according to claim 1,

wherein the spectrometric sensor is an ion-mobility sensor.

10. The apparatus according to claim 1,

wherein the spectrometric sensor is a mass spectrometry sensor.

5. A method that controls an apparatus including:

a detection unit detecting chemical substance-related information relating to a chemical substance included in a fluid at a sampling point using an ion mobility sensor;

a communication unit that communicates wirelessly or via wires with an outside device;

a local memory storing a threat detection library including a specifying pattern generated when a specified chemical substance that is a cause of a threat was detected by a spectrometric sensor; and

a processor,

the processor executing;

a matching process which routinely compares chemical substance-related information obtained by the detection unit and a specifying pattern for monitoring purposes included in the threat detection library and outputs match information when the obtained chemical substance-related information and the specifying pattern for monitoring purposes match; and

in parallel or according to time division with the matching process, a process that determines that an event relating to an odor has occurred based on a change in a chemical constituent or a change in concentration of detected chemical substances included in the obtained chemical substance-related information, and outputs an occurrence of an event and an occurrence cause of the event, the process including transferring, via the communication unit, the chemical substance-related information to the outside device and obtaining the occurrence cause of the event including chemical substances estimated from the chemical substance-related information and/or a cause of outputting of the estimated chemical substances.

6. The method according to claim 5,

further comprising the processor acquiring a specifying pattern of a chemical substance that poses a threat based on the occurrence cause of the event via the communication unit and updating the threat detection library in the local memory using the acquired specifying pattern.

7. The method according to claim 5,

further comprising the processor acquiring event appended information including images and/or sound around the apparatus, and

the processor interpreting a state based on the images and/or sound included in the event appended information, acquiring, via the communication unit, a specifying pattern including elements of an odor that poses a threat in the state, and updating the threat detection library in the local memory using the acquired specifying pattern.

8. A nontransitory computer readable medium encoded with a program executed by an apparatus including:

a detection unit detecting chemical substance-related information relating to a chemical substance included in a fluid at a sampling point using a spectrometric sensor;

a communication unit that communicates wirelessly or via wires with an outside device;

a local memory storing a threat detection library including a specifying pattern generated when a specified chemical substance that is a cause of a threat was detected by the spectrometric sensor; and

a processor,

the program comprising instructions that have the processor execute;

a matching process which routinely compares chemical substance-related information obtained by the detection unit and a specifying pattern for monitoring purposes included in the threat detection library and outputs match information when the obtained chemical substance-related information and the specifying pattern for monitoring purposes match; and

,

in parallel or according to time division with the matching process, a process that determines that an event relating to an odor has occurred based on a change in a chemical constituent or a change in concentration of detected chemical substances included in the obtained chemical substance-related information, and outputs an occurrence of an event and an occurrence cause of the event, the process including transferring, via the communication unit, the chemical substance-related information to the outside device and obtaining the occurrence cause of the event including chemical substances estimated from the chemical substance-related information and/or a cause of outputting of the estimated chemical substances.
