Diagnostic device and a data communication system for use with the diagnostic device
First Claim
1. A diagnostic device for determining countermeasures to a failure of a machine, comprising:
- a map memory storing a countermeasure map, in which failure codes, representing various symptoms of failures, are each associated with at least a countermeasure code representing a possible countermeasure and probability data indicating a probability of success of said possible countermeasure;
data input means allowing data to be input into the diagnostic device in form of codes;
search means for searching said countermeasure map in response to a search code input through said data input means, said search code including a first one of said failure codes which corresponds with said failure of said machine, said search means reading at least a first one of said countermeasure codes which are assigned to said first failure code; and
display means for displaying at least data of a first countermeasure stored in said map memory in correspondence with said first countermeasure code along with the probability data stored in said map memory in correspondence with said first countermeasure code.

Abstract
A diagnostic device displays at least an optimum countermeasure in response to a failure code inputted in accordance with a failure of a machine, as a result of searching a countermeasure map, in which each failure code is associated with at least a countermeasure code. After taking a countermeasure with reference to display of the diagnostic device, the repairer inputs a countermeasure code corresponding to the taken countermeasure and a result code indicating the result of the countermeasure. The failure code, the countermeasure code and the result code are stored as repair data in the diagnostic device. The repair data is sent to a host computer over a telephone line. The host computer gathers the statistics of the repair data to revise the countermeasure map.

9. A data communication system for providing communication between a plurality of diagnostic devices and a host computer, comprising:
-
a terminal connectable to said diagnostic devices; and a modem coupled to said terminal for connecting said terminal to said host computer, through a telephone line, to send repair data from said diagnostic devices to said host computer over said telephone line, said repair data comprising at least a failure code representing a symptom of failure, a countermeasure code representing a countermeasure taken for said failure and a result code representing whether said countermeasure succeeded or not, said host computer statistically processing said repair data to make a countermeasure map in which many kinds of failure codes representing various symptoms of failures are each associated with at least a countermeasure code representing a possible countermeasure and data representing a probability of success of said possible countermeasure. - View Dependent Claims (10, 11, 12)
