Problems solved by technology

In the traditional traction brake level control method, no matter in automatic driving mode or manual driving mode, the level signal and TCMS are only a single hard-wired interface, and TCMS lacks redundant mechanisms and diagnostic mechanisms for hard-wired signal acquisition And the safety-oriented mechanism, when the interface fails, it will easily lead to the downgrade of the train operation level, and may even cause the train to break the standard and other faults that seriously affect the train operation order

Embodiment Construction

[0034] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] The traction braking level of rail trains is mainly derived from the signal system output (VOBC) of the automatic driving mode (ATO) and the controller (MC) output of the manual driving mode. The VOBC output in ATO mode is interfaced with the train network control system as a hard-wired signal, usually a 4-20mA current signal or a 0-10V voltage signal. 20mA current signal is mostly. The interface between the MC output in the manual driving mode and the TCMS is a hard-wire signal, usually a 0-10V voltage signal or a PWM signal. In recent years, the traction brake level signal output by the MC in the subway train project is mostly a 0-10V voltage signal. In this embodiment, taking the traction braking level control of a subway train as an example, a traction braking level control method is designed, including:

Abstract

The invention relates to a control method of the traction braking level of a rail train. The control method comprises the steps that train running mode information is acquired, wherein a TCMS system redundantly acquires traction braking level information output by a signal system of an automatic driving mode or traction braking level information output by a controller of a manual driving mode through a remote input and output unit (RIOM); and real-time communication diagnosis is carried out on the remote input and output unit (RIOM), and the traction braking level information collected by theremote input and output unit (RIOM) is used for controlling the traction braking level of the rail train in an automatic driving mode or a manual driving mode correspondingly. According to the controlmethod, through redundant acquisition, real-time diagnosis and logical judgment of signals in a train network control system, the control strategy of train traction braking level control is optimized, the real-time and synchronization of signal transmission are improved, the availability of vehicles is improved, and the advantages of reliability and safety of centralized control of the train network control system are brought into play.

Description

technical field [0001] The invention belongs to the technical field of vehicle traction braking control, and in particular relates to a method for controlling the level of traction braking of rail trains. Background technique [0002] The main function of the train network control system (hereinafter referred to as TCMS) is to realize the centralized control function of the train subsystems and vehicles. The more complex it is, the higher the reliability requirements for the control strategy of the train network control system. [0003] The rail train traction braking level mainly comes from the output of the signal system (hereinafter referred to as "VOBC") in the automatic driving mode (automatic driving) and the output of the controller (hereinafter referred to as "MC") in the manual driving mode (manual driving). Usually, the interface between the VOBC output in the automatic driving mode and the train network control system is a hard-wire signal, and the analog signal ...
