Time calibration method of vehicle-mounted equipment and storage medium

The invention relates to a timing method of vehicle-mounted equipment and a storage medium, and relates to the timing method of the vehicle-mounted equipment and the storage medium. The invention aims to solve the problem that the timing time is not accurate enough due to the fact that locomotive on-board equipment cannot meet the requirement of responding to a timing command of a timing device with the highest priority. The method comprises the following steps: firstly, according to the time T0 of the vehicle-mounted equipment acquired by the time corrector, calculating the difference value delta T between the time of the vehicle-mounted equipment and the time T1 of the time corrector according to delta T = T1-(T0 + Ttrans), and the Ttrans is transmission delay; and then, the timing device sends a timing command, the difference value delta T is sent to the vehicle-mounted equipment, and the vehicle-mounted equipment adjusts the time according to the time difference value delta T. The method is used for timin
