Abstract

The embodiment of the present invention discloses a wind pressure calibration method and device. The wind pressure calibration method includes: when a wind pressure calibration command is received, acquiring the air wind pressure value of the main engine detection station at the end of the row to be calibrated and collecting the The wind pressure value of the air duct of the main engine at the end of the column to be calibrated currently; determine the target calibration value based on the wind pressure value in the air, and calibrate the wind pressure value of the air duct of the main engine at the end of the column to be calibrated based on the target calibration value to obtain the The current wind pressure value of the main engine at the end of the column to be calibrated. The accuracy of wind pressure calibration can be improved by adopting the invention.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a wind pressure calibration method and device. Background technique [0002] With the continuous development of rail transportation technology, more and more passengers choose rail transportation trains to travel. In order to meet the travel requirements of passengers, the speed of the train has been increased many times. At the same time, the risk of train brake failure is also increasing. [0003] At present, safety protection is usually carried out by installing a train tail safety protection device (hereinafter referred to as the passenger train tail device) at the train tail. The passenger train tail device can be connected to the train air duct, and communicate with the LBJ (train protection and alarm equipment) installed at the head of the train, and perform auxiliary exhaust brake on the train by returning the wind pressure information at the train tail. Speci...
