The utility model provides an error recognition device for continuous concora crush control system that troops, error recognition device includes: detecting element, its error information that is used for detecting the control system that troops, the unit is confirmed to error grade string, and it is used for according to the error information that detects, definite control system's that troops error grade string, coding unit, it is used for obtaining the error hamming code behind the code through carry out the hamming code to error grade string, recognition cell, it is arranged in discerning the passage that the error appears in the control system that troops based on the error hamming code behind the code. The utility model discloses an above -mentioned technique can realize more accurate error discernment, the discernment of the error grade of variable figure in the certain limit can be realized in the error state word code position that only utilizes fixed figure place in the error identifying, and need not change the data line width of the hardware unit that transmission and institute of computing technology needed.
