Abstract

The invention discloses an integrated multifunctional parking braking system and a control method thereof. A first bi-directional valve, a dust filtration check valve, a pressure reducing valve, a parking braking electromagnetic valve, a second bi-directional valve, an electric interlocking cock and an outlet in the system are connected in sequence. The first bi-directional valve is connected with a first air source and a second air source. A parking braking air cylinder is arranged between the dust filtration check valve and the pressure reducing valve. The second bi-directional valve is connected with a comparison outlet. A first pressure switch and a second pressure switch are arranged between the electric interlocking cock and the outlet. The integrated multifunctional parking braking system and the control method thereof have the advantages that the original parking braking function is reserved, meanwhile, the function of the double air sources from a total air pipe and a train pipe (or other external air sources) is achieved, and it can be guaranteed that parking braking can be automatically implemented when total air does not exist; meanwhile, the functions of parking braking status display, mechanical display or digital display, manual release and the like can be achieved; an air board integration mode is adopted, the size is small, the integration degree is high, and rapid installation or maintenance is facilitated.

Description

technical field [0001] The invention belongs to the technical field of locomotive air braking, and in particular relates to an integrated multifunctional parking braking system and a control method thereof. Background technique [0002] Existing parking brake systems such as figure 1 As shown, it includes: filter 1, pressure reducing valve 2, double pulse solenoid valve 3, two-way check valve 4, pressure switch 5, pressure measuring point 6, live node exhaust plug 7, etc., among which: filter 1, Pressure reducing valve 2, double pulse solenoid valve 3, two-way check valve 4 and live node exhaust plug door 7 are connected in sequence, and pressure switch 5, pressure Measuring point 6. The existing parking brake system controls the braking or relief of the parking brake by accepting the instructions of the train control system through the control device. The passage between the total wind and the brake cylinder is controlled to be closed through the passage of the double pu...
