Description

BACKGROUND The present information relates to an information collection system and an information collection method, and is suitable for application to, for example, an information collection system and an information collection method for collecting information related to ride quality. As a technique for monitoring train ride quality affected by train vibrations during running, a state monitoring system has been disclosed in which, to maintain the ride quality of cars using as few sensors as possible, problems are detected by installing vibration accelerometers, for example, over car body floor portions around bogies and on axle boxes provided for wheels and measuring vibrations using the vibration accelerometers installed (see Japanese Unexamined Patent Application Publication No.2011-51518). SUMMARY However, it is difficult to install, according to the state monitoring system disclosed in Japanese Unexamined Patent Application Publication No.2011-51518, acceleration sensors for measuring vibrations to affect ride quality in locations suitable for measurement inside cars of a train being commercially operated without spoiling the interior appearance of the cars and without interfering with passengers. Also, to comprehensively collect data from each car of all trains, there is a problem that installing a set of sensing devices including power supplies, data collection devices, etc. involves a high cost. The present invention has been made taking the above aspects into consideration and is intended to propose an information collection system and an information collection method which can realize comprehensively collecting information related to ride quality at a low cost. To achieve the above object, according to the present invention, an acquisition unit and a processing unit are provided. The acquisition unit acquires, from a mobile terminal possessed by a passenger of a mobile object, mobile-object state information indicating a state of the mobile object and boarding identifying information to identify a time when and a location where the passenger boards the mobile object. The processing unit, based on time information given when the mobile-object state information is acquired, associates location information on the mobile object given when the mobile-object state information is acquired, the mobile-object state information, and the boarding identifying information and stores in a storage unit. According to the above configuration, for example, mobile-object state information is acquired as information related to ride quality from a mobile terminal possessed by a passenger of a mobile object, so that it is not necessary to newly install sensors for acquiring information related to ride quality. This makes it possible to realize comprehensively collecting information related to ride quality at a low cost. According to the present invention, comprehensively collecting information related to ride quality can be realized at a low cost. Objects, configurations, and effects other than those described above of the present invention will be made clear by the following description of embodiments BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an example configuration of an information collection system according to a first embodiment.FIG. 2 shows an example configuration of an information processing unit according to the first embodiment.FIG. 3 shows an example flowchart for information processing performed at a mobile terminal according to the first embodiment.FIG. 4 shows an example flowchart for information processing performed at an information processing unit according to the first embodiment.FIG. 5 shows an example flowchart for abnormality detection processing according to the first embodiment.FIG. 6 shows an example flowchart for information processing performed at a mobile terminal according to the first embodiment.
