The invention provides a methane safety guarantee system of a dual-fuel locomotive. The dual-fuel locomotive comprises an LNG (liquefied natural gas) tank, an engine, an auxiliary convertor block and a power house, and is characterized in that the system comprises a capacitance liquid level indicator, a pressure sensor, a liquid level sensor, a liquid supply cut-off valve, an emergency cut-off valve, a locomotive microcomputer, at least one body ventilator, an anti-explosion body ventilator, a methane detection host, a plurality of methane sensors, a gasifier, a safety valve, an air solenoid valve, a blow off valve, an inverter power supply and a storage battery, wherein the capacitance liquid level indicator, the pressure sensor and the liquid level sensor are arranged in the LNG tank. According to the methane safety guarantee system provided by the invention, safety guarantee control is performed on the dual-fuel locomotive, so the application safety of the dual-fuel locomotive can be enhanced to a great extent.
