Study on Non-Explosive Assessing System for Intrinsically Safe Circuit

Due to the advantages of the intrinsically safe circuit, people are increasingly willing to make use of it in comprehensive automatization system and communication equipment. If practical non-explosive testing methods can be constructed base on discharge theory of intrinsically safe circuit, the designers will find it easier to grasp the performance of the circuit, thus resulting in the achievement of shorter researching time and lower costs. This thesis has established the non-explosive assessment system of the intrinsically safe circuit with ANFIS as its core. ANFIS input Eigenvector has been affirmed according to the circuit quality, experimental gas types, discharge power, maximum value of the instantaneous power, the energy comparison of the average power value and the discharge time. The system uses the explosive experimental data from the spark test system to extract the Eigenvector to perform ANFIS training. After succeed training, the established circuit discharge models are used to extract the Eigenvector to make the assessment of the non-explosive intrinsically safe performance of the intrinsically safe circuit. According the explosive experiment, this system boasts high accuracy and practical value.
