Abstract

The invention relates to the technical field of hydrogen safety management, and provides an energy-saving hydrogen fuel automobile hydrogen concentration alarm sensor and an alarm method. The energy-saving hydrogen fuel automobile hydrogen concentration alarm sensor comprises a vehicle signal input end, a primary alarm circuit and a secondary alarm circuit, wherein the vehicle signal input end is electrically connected with the primary alarm circuit and the secondary alarm circuit, when the hydrogen concentration of the detection position is larger than a first preset value and smaller than a second preset value, the primary alarm circuit starts primary alarm, and when the hydrogen concentration of the detection position is larger than or equal to the second preset value, the secondary alarm circuit starts secondary alarm. The energy-saving hydrogen fuel automobile hydrogen concentration alarm sensor can be suitable for vehicle running scenes, energy consumption is basically zero under the condition that the hydrogen concentration is low, the requirement for static power consumption of the whole vehicle is well met, safety state detection of vehicle hydrogen safety can be achieved on the premise that energy is saved, and the sensor has the advantages of being simple in structure, high in reliability, high in stability, good in energy-saving performance and the like.

Description

technical field [0001] The invention relates to the technical field of hydrogen safety management, in particular to an energy-saving hydrogen fuel vehicle hydrogen concentration alarm sensor and an alarm method. Background technique [0002] With the popularization of hydrogen fuel cell vehicles, people pay more and more attention to hydrogen safety. The existing hydrogen concentration sensors have high power consumption because they are not suitable for the structure of the whole vehicle, and the application scenarios are not strong, making the traditional hydrogen concentration sensor Sensors are not well suited for vehicle applications. Contents of the invention [0003] The invention provides an energy-saving hydrogen fuel vehicle hydrogen concentration alarm sensor and an alarm method, aiming to solve the technical problems of high power consumption and poor applicability of traditional hydrogen concentration sensors. [0004] In order to achieve the above object, th...
