The invention discloses a control method and system of a tread cleaning valve and a locomotive, and relates to the technical field of rail transit vehicles. The tread cleaning device comprises a plurality of tread cleaning valves, a self-resetting tread cleaning switch and a CCU, and the air path input end of each tread cleaning valve is provided with one pressure detection device. The pressure detection device is used for obtaining the pressure value of the input end of the tread cleaning valve gas circuit. And the tread cleaning switch, the plurality of tread cleaning valves and the plurality of pressure detection devices are all electrically connected with the CCU. And the tread cleaning switch is used for sending a manual opening instruction of the tread cleaning valve to the CCU. The CCU is configured or programmed as steps for implementing the control method of the tread purge valve. According to the invention, the plurality of tread cleaning valves are controlled in a grouping and time-sharing manner through the CCU, so that the impulse is reduced when the tread cleaning is executed.
