The data of air pressure test device have different resistive currents under different load strengths, so it is necessary to collect the data of locomotive air pressure test device automatically, and the automatic data acquisition method of locomotive pressure test device based on fuzzy algorithm is put forward. Such elements can also be integrated to the health care system. The input control variable model of locomotive air pressure test device data calculation is constructed. Under the adjustment of pressure and pressure gain, the locomotive no-load output pressure is used as the state characteristic quantity, the output stability of locomotive pressure test device data is analyzed under the mode of high switching frequency, and the electromagnetic interference characteristics of locomotive pressure test device data output are analyzed by combining the adaptive error feedback adjustment method. According to the fuzzy state characteristics of locomotive air pressure test device, the vibration analysis and error adjustment of locomotive pressure test device data are carried out, and the adaptive parameter fusion model of locomotive pressure test device data is established. Combined with virtual air pressure adaptive control and output power adaptive adjustment method, the automatic data acquisition of locomotive pressure test device is realized. The simulation results show that the automatic data acquisition accuracy and stability of the locomotive air pressure test device are high, and the adaptability and environmental adaptability of the data calculation of the locomotive pressure test device are improved.
