Abstract

The invention discloses a metro vehicle pulse-type mechanical odometer value adjusting device, and belongs to the technical field of pulse-type mechanical odometer adjustment. The device comprises a power supply module DC, a circuit breaker, a relay, a power-off delay module DM and a pulse-type mechanical odometer. The metro vehicle pulse-type mechanical odometer value adjusting device provided by the invention is suitable for different pulse time designs, can adapt to pulse-type mechanical odometers in different metro projects, has certain versatility, and can simultaneously adjust a plurality of pulse-type mechanical odometers as needed. Artificial manual adjustment is adopted in the prior art, so specially-assigned person must continuously work for many days when the value to be adjusted is large. The device saves certain manpower.

Description

technical field [0001] The invention belongs to the technical field of pulse-type mechanical odometer adjustment, and in particular relates to a numerical adjustment device for a pulse-type mechanical odometer of a subway vehicle. Background technique [0002] The mileage display of subway vehicles is usually divided into two parts, namely the pulse type mechanical odometer and the HMI (driving screen) display. When the train travels a certain mileage and the pulse type mechanical odometer fails and needs to be replaced with a new one, the mileage of the new meter needs to be adjusted to the mileage of the faulty meter. [0003] Take Shanghai Metro Line 13 as an example: every time the train runs for 1km, the brake system sends out a 110V pulse lasting 5s, and the pulse-type mechanical odometer reads 1km after receiving this pulse. The principle of the pulse mechanical odometer of other projects is similar, the difference is the pulse duration, but the time values ​​are all...
