In order to ensure the accuracy and reliability of the measurement values of the detection station of the end-of-passenger-train safety equipment host,the requirements of the special calibration device for detection station of the end-of-passenger-train safety equipment host is proposed according to JJF(CR)043—2022 Detection station of the end-of-train safety equipment host.The special calibration device for the detection station of the end-ofpassenger-train safety equipment host is developed by adopting modular design and digital integration technology.The paper introduces the composition and calibration principle of the special calibration device for the detection sta⁃tion of the end-of-passenger-train safety equipment host,and evaluates the uncertainty of the calibration result of the detection station of the end-of-passenger-train safety equipment host.The evaluation results show that the uncer⁃tainty of the calibration results of pressure,DC voltage and DC current is less than 1/3 of the maximum allowable er⁃ror.The special calibration device for detection station of the end-of-passenger-train safety equipment host can be used to calibrate the detection station of the end-of-passenger-train safety equipment host.The field application proves that the special calibration device for the detection station of the end-of-passenger-train safety equipment host can automatically collect and process the calibration data and output the calibration result,which is convenient for on-site calibration and improves the calibration efficiency.
