The intelligent meat resistance determine system was designed by using constant current source circuit,double frequency alternating current generator,alternating measure circuit,double single chip computer interior communication and real-time exterior serial communication,which would measure automatically various parameter of electrical impedance of carcasses after slaughter as the change of environment temperature,with date collected by single chip computer,A/D transformation and data storage and the storage data transmitted to computer by R232 or USB communication line.Based on the analysis of resistance,frequency,measure time,measure speed and measure temperature,the computer would automatically output a measure curve.After compared with curves from databank based on genetic and breeding measure,intelligent meat quality assessment would be given.
