Abstract
Abstract A remote diagnosis system for a numerical control apparatus for diagnosing the operation state of the numerical control apparatus by means of a terminal unit disposed away from the numerical control apparatus by transmitting image data of the numerical control apparatus from a diagnosis data transmitting unit attached thereto to the numerical control apparatus includes: an image data read out unit for reading out an image data corresponding to one character in character representation from an image storage unit bearing the image data; and a character coding unit for transforming the image data into a character code if a character code exists corresponding to the image data read out by the image data read out unit.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
195 words
A remote diagnosis system for a numerical control apparatus which is capable of diagnosing the operation state of said numerical control apparatus by means of a terminal unit disposed away from said numerical control apparatus by transmitting image data of said numerical control apparatus from a diagnosis data transmitting unit attached thereto to said numerical control apparatus, comprising: an image data read out means for reading out image data corresponding to one character in character representation from an image storage means bearing said image data, said image data including a number of dots which are in a first state; and a character coding means for counting the number of dots in said image data which are in said first state, and for comparing said image data with reference dot pattern data which have been initially indexed based on said number of dots in said first state and dot patterns in specific rasters of said image data, and for converting said image data into character code when said image data coincides with said reference dot pattern data and for generating a graphic code when said image data fails to coincide with said reference dot pattern data.
Claim 2
Dependent Claim
195 words
A remote diagnosis system for a numerical control apparatus which is capable of diagnosing the operation state of said numerical control apparatus by means of a terminal unit disposed away from said numerical control apparatus by transmitting image data of said numerical control apparatus from a diagnosis data transmitting unit attached thereto to said numerical control apparatus, comprising: an image data read out means for reading out image data corresponding to one character in character representation from an image storage means bearing said image data, said image data including a number of dots which are in a first state; and a character coding means for counting the number of dots in said image data which are in said first state, and for comparing said image data with reference dot pattern data which have been initially indexed based on said number of dots in said first state and dot patterns in specific rasters of said image data, and for converting said image data into character code when said image data coincides with said reference dot pattern data and for generating a graphic code when said image data fails to coincide with said reference dot pattern data.
Claim 3
Dependent Claim
82 words
A remote diagnosis system for a numerical control apparatus as claimed in claim 1, wherein said image data read out means comprises an image storage memory for storing the image data, a write address counter for assigning inside addresses of said image storage memory, a column-address designating section for designating column-address of said image storage memory, a row-address designating section for designating row address of said image storage memory and a raster counter for counting raster numbers for said image storage memory.
