COLLECTION SYSTEM, COLLECTION APPARATUS, METHOD AND PROGRAM FOR THE SAME
The present invention provides a technology of efficiently collecting abnormal state data important in a safety function or automatic driving. A collection system includes a passenger sensor unit configured to sense the passenger; and a determination acquisition unit configured to acquire abnormality data from data related to a vehicle and not to the passenger based on sensor information which is data acquired by the passenger sensor unit. The determination acquisition unit determines a danger based on an action taken by a person who senses the danger or changing biological information, and acquires data acquired by the sensor for a time in which the danger is determined and a time with a predetermined length continuing before or after the time as the abnormality data.
1 . A collection system that collects abnormality data acquired by a sensor mounted on a vehicle or a passenger aboard the vehicle, the collection system comprising:
a passenger sensor sensing the passenger; and
processing circuitry configured to:
execute a determination acquisition processing in which the processing circuitry acquires abnormality data from data related to the vehicle and not to the passenger based on sensor information which is data acquired by the passenger sensor,
wherein in the determination acquisition processing the processing circuitry determines a danger based on an action taken by a person sensing the danger or changing biological information, and acquires data acquired by the sensor for a time in which the danger is determined and a time with a predetermined length continuing before or after the time as the abnormality data.
2 . The collection system according to claim 1 ,
wherein the passenger sensor is a microphone collecting a voice spoken by the passenger, and
wherein in the determination acquisition processing the processing circuitry performs voice recognition on the collected voice and determines a danger when speech spoken when the person senses the danger is included.
3 . The collection system according to claim 1 ,
wherein the passenger sensor is a microphone collecting a voice spoken by the passenger, and
wherein in the determination acquisition processing the processing circuitry determines that there is an abnormality when a volume of the collected voice is equal to or greater than a predetermined threshold.
4 . A collection apparatus that collects one or more pieces of sensor information which are data acquired by one or more sensors mounted on a vehicle or a passenger aboard the vehicle, the collection apparatus comprising:
processing circuitry configured to:
perform voice recognition using a voice signal collected by a microphone mounted on the vehicle or the passenger aboard the vehicle;
select more sensor information when a voice recognition result includes speech spoken at a time at which a person senses a danger than a time at which the voice recognition result does not include the speech spoken at the time at which the person senses the danger; and
transmit the sensor information selected via a communication line to a data collection server.
5 . A collection system that collects abnormality data acquired by a sensor mounted on a vehicle or a passenger aboard the vehicle, the collection system comprising:
a microphone collecting an acoustic signal output from an outside of a space in which the passenger in the vehicle stays; and
processing circuitry configured to:
execute a determination acquisition processing in which the processing circuitry determines whether a klaxon is included in a collected signal and acquires data acquired by the sensor for a time at which the klaxon is determined to be included and a time with a predetermined length continuing before or after the time as abnormality data.
6 . A collection method, implemented by a passenger sensor and a collection apparatus that includes processing circuitry, of collecting abnormality data acquired by a sensor mounted on a vehicle or a passenger aboard the vehicle, the collection method comprising:
a passenger sensing step in which the passenger sensor unit sensing senses the passenger; and
a determination acquisition step in which the processing circuitry acquires abnormality data from data related to the vehicle and not to the passenger based on sensor information which is data acquired in the passenger sensing step,
wherein, in the determination acquisition step, the processing circuitry determines a danger based on an action taken by a person sensing the danger or changing biological information, and acquires data acquired by the sensor for a time in which the danger is determined and a time with a predetermined length continuing before or after the time as the abnormality data.
7 . A collection method, implemented by a collection apparatus that includes processing circuitry, of collecting one or more pieces of sensor information which are data acquired by one or more sensors mounted on a vehicle or a passenger aboard the vehicle, the collection method comprising:
a sound recognition step in which the processing circuitry performs voice recognition using a voice signal collected by a microphone mounted on the vehicle or the passenger aboard the vehicle;
a transmission data selection step in which the processing circuitry selects more sensor information when a voice recognition result includes speech spoken at a time at which a person senses a danger than a time at which the voice recognition result does not include the speech spoken at the time at which the person senses the danger; and
a data transmission step in which the processing circuitry transmits the sensor information selected to a data collection server via a communication line.
8 . A non-transitory computer-readable recording medium having recorded thereon a program causing a computer to function as the collection apparatus according to claim 4 .
