In view of the harmful gas monitoring system of metallurgy production environment the problem of real-time and accuracy is not strong. Designed and implemented based on light ion sensor PID - A1 associated metallurgy toxic gas monitoring system of the model. Hardware part designs the light sensors PID - A1 gas detection circuit, main control circuit, etc., of a data processing P89V51RD2FN chip software design including software workflow, light sensors PID - A1 correlation program implementation, etc. Simulation experiment results show that the system is maintained steady decline, finally achieve stability near the detection accuracy of 86%, the average detection accuracy is about 54% higher than that of the traditional system, metallurgy dramatically improve production environment.
