  • Patent number: 8102247
    Abstract: The present invention is provided to suppress an increase of communication cost, immediately detect theft and illegal use of a moving object, and immediately deal with the theft and illegal use. A moving object monitoring device 10 is installed in a moving object 1, and transmits moving object information 15 of the moving object 1 to a managing server 4 which controls the moving object 1. The moving object monitoring device 10 includes a control unit 11 which transmits the moving object information 15 such that a transmission interval is shorter when a startup lock function for prohibiting the startup of the moving object is on than a transmission interval when the startup lock function is deactivated.

  • Patent number: 7925396
    Abstract: The present invention reduces power consumption as much as possible when an engine is off state. A mobile object monitoring device 40, which is installed in a mobile object 10 with an engine 11 as a drive source, includes a monitoring control unit 41 that collects information about the mobile object 10, and a work control unit 42 that controls work of the monitoring control unit 41. The work control unit 42 activates the monitoring control unit 41 according to an intermittent work schedule S3 in which an operation rate is gradually decreases until a continuous working time of the engine 11 exceeds a predetermined threshold W0 after the engine 11 becomes off state.
