Synchronous control method and system of track vehicle air conditioning system by ground two cabs

Abstract

The invention discloses a synchronous control method and system of a track vehicle air conditioning system by ground two cabs. The method comprises the steps that the air conditioning system is electrified; a data processing unit identifies a plurality of control signals in time, and determines a final effective control signal; the ventilation status of the air conditioning system is detected; and the data processing unit acquires the final effective control signal, transmits the final effective control signal to the air conditioning system to execute the corresponding operation condition, and keeps a record in time. The system comprises an electrifying unit, a signal identifying unit, a ventilation status detecting unit, an air conditioning executing unit, and a power failure judging unit. The synchronous control method and system achieve that three control signals are issued simultaneously and arbitrarily in the two cabs, and the data processing unit can automatically identify the final roll-in operation condition of the current air conditioning system and keep a record in time. The operating process is simplified, the conflicts between the control signals are avoided effectively through the setting of priorities, and reliability is greatly improved. The synchronous control method and system can be widely applied to the field of air conditioners.

Description

technical field [0001] The invention relates to the technical field of rail vehicle air conditioning, in particular to a method and system for synchronously controlling two driver's cabs on the ground of a rail vehicle air conditioning system. Background technique [0002] The control of the air-conditioning system in the rail vehicle driver's cab is divided into two types: network command signal and hard-wire electric signal. Due to the uniqueness of the command issued by the network command signal, it can ensure that the two driver's cabs can control each other at the same time without interfering with each other. For the mechanical universal switch, the central data processing unit receives high and low level signals. In many cases, simultaneous effective control of the air conditioning system in both cabs cannot be recognized. At present, the way to adopt the mechanical ten thousand-turn switch control for two cabs is to turn the mechanical ten thousand-turn switch at o...
