PROBLEM TO BE SOLVED: To provide an on-vehicle communication machine capable of surely sending positional information of an object device to a management center.SOLUTION: An on-vehicle communication machine 3 comprises a radio communication part for communicating with another communication machine by radio communication, a storage part, and a control part. The storage part stores a search database and a detection database. The control part of the on-vehicle communication machine 3 creates detection information containing positional information on the basis of device information when receiving the device information from a pedestrian terminal which is a search object and which has been registered in the search database, and then registers the created detection information in the detection database. The control part of the on-vehicle communication machine 3 sends the detection information registered in the detection database to a road side communication machine 2 via the radio communication part, when receiving the device information from the road side communication machine 2 installed on the road side, via the radio communication part.SELECTED DRAWING: Figure 4 |
