A diagnostic device detects a fault and estimates its cause based on the degree of change of measured data attributes. A diagnostic object change degree pattern (CDP) generation unit calculates the degree of change of each attribute of data, including attributes of the object being diagnosed measured from the object being diagnosed to generate a diagnostic object CDP which is a combination of values of the degree of change of the respective attributes. A criterion CDP memory holds in store a criterion CDP, formed of a pattern of values of the degree of change of the attributes of data measured from the object being diagnosed, in association with event(s)-to-be-diagnosed on the fault sort basis or on the fault cause basis. A CDP diagnosis unit effects pattern matching between the diagnostic object CDP and the criterion CDP in the criterion CDP memory to diagnose the object being diagnosed.

Diagnostic device

The present invention provides a diagnostic system that diagnoses a diagnostic object by applying a diagnostic rule to data measured on the diagnostic object wherein an object of the present invention is to allow the diagnostic rule to be updated based on a variety of diagnostic case data. Each of multiple diagnostic devicesmakes a diagnosis by applying a diagnostic rule to diagnostic object data measured on a diagnostic objectand sends diagnostic case data, which includes diagnostic object data and its diagnostic result, to a diagnostic rule generation devicevia a network. The diagnostic rule generation devicegenerates a diagnostic rule based on the diagnostic case data received from the multiple diagnostic devicesand sends the generated diagnostic rule to the diagnostic devicesvia the network. The diagnostic devicesupdate a diagnostic rule in their devices with the diagnostic rule received from the diagnostic rule generation device

Diagnostic system

The route search system of the present invention receives the provision request of the information about route search from a route search terminal. The information included in the provision request from a route search terminal is acquired, calculation processing of the environmental load value of the relevant vehicle and the environmental load value of other vehicle by which it is generated with movement of a relevant vehicle from the acquired information is carried out using an environmental load calculation unit.

Route search system, route search terminal and route search method

The data processing system of the present invention is provided with a center server that, upon receiving mobile data and mobile unit identifier from a portable information terminal, transmits edited data that are produced from the mobile data, a server identifier that is the transmission destination, and a mobile unit identifier to the outside by way of a communication network, and is also provided with a separate verification server. The verification server stores private information in advance, and transmits by way of a communication line directly to transmission destinations private information that matches with the mobile unit identifier that is received from the center server, whereby the danger of disclosing private information on the communication network can be reduced.
