Abstract: A communication system includes a relay device and a diagnosis target device. The relay device includes a port configured to connect a diagnostic tool. The diagnosis target device is connected to the relay device via a bus. When the diagnosis target device has received specific data whose source appears to be the diagnostic tool, the diagnosis target device sends an inquiry signal for inquiring of the relay device about a monitoring result for the specific data. The relay device determines in response to the inquiry signal whether the specific data is legitimate data from the diagnostic tool. The relay device sends the monitoring result including a determination result to the diagnosis target device.

Abstract: A processor of a vehicle monitoring device obtains log information of an event that has occurred in a vehicle on-board device, determines whether a diagnosis is necessary based on the obtained log information, and transmits a diagnostic data set to an external server when determining that a diagnosis is necessary. The diagnostic data set transmitted to the server by the processor includes log information based on which a diagnosis is determined to be necessary, log information that is obtained prior to the determination, and log information that is obtained after the determination.

Abstract: A communication system includes a relay device and a diagnosis target device. The relay device includes a port configured to connect a diagnostic tool. The diagnosis target device is connected to the relay device via a bus. The relay device determines whether a communication path of diagnostic data for diagnosing the diagnosis target device is correct when the relay deice has received the diagnostic data, the diagnostic data being data that is transferred between the relay device and the diagnostic tool. The relay device sends to the diagnosis target device a monitoring result including a determination result as to whether the communication path of the diagnostic data is correct.

Abstract: A control device comprising a processor, wherein the processor is configured to: acquire a warning level indicating a warning measure related to an abnormality that has occurred in a vehicle, from a device installed externally to the vehicle; detect an abnormality that has occurred in the vehicle, from equipment mounted to the vehicle; perform thinning control on a detection result of the abnormality detected according to the warning level; and transmit the detection result resulting from thinning to the device.

Abstract: In a security system, a first collecting module cyclically collects target-object information indicative of environments of a target object and a monitored area in which the target object exists. An alarm module determines whether there is an abnormal situation associated with at least one of the target object and the monitored area based on the target-object information, and sets off an alarm indicative of a result of the determination that there is an abnormal situation. A second collecting module cyclically collects circumstance information indicative of a situation of an area surrounding the monitored area. An abnormal situation determining module calculates, based on the circumstance information, a probability that an abnormal situation associated with at least one of the target object and the monitored area will occur, and determines whether the probability is equal to or higher than a threshold level.

Abstract: A condition monitoring apparatus includes: a route-control means which sets a set-route and controls equipment so that the equipment moves according to the set-route; an information-collection means which repeatedly acquires information indicating a condition of a first target; an abnormality-confirming means which determines whether the first target is abnormal; a route-acquisition means which acquires position information indicating a position of each monitoring terminal that monitors a condition of a second target, and confirms presence/absence of a monitoring-required area of which a condition is required to be monitored in a monitoring-target area larger than a monitoring area in which the second target is present, and in which the equipment does not move according to the set-route, the route-acquisition means acquiring a changed-route which leads the equipment to a destination through the monitoring-required area; and a mute-change means which sets the changed-route as the set-route when the route-acqui
