Hydrogen fuel automobile hydrogenation monitoring system and monitoring method thereof

Abstract

The invention discloses a hydrogen fuel automobile hydrogenation monitoring system and a monitoring method thereof, and belongs to the technical field of automotive engineering. The hydrogen fuel automobile hydrogenation monitoring system comprises a proximity switch, a pyroelectric sensor, a pressure sensor, a feedback module, a hydrogenation opening cabin door opening and closing mechanism and acontrol unit. The proximity switch is connected with the control unit and outputs hydrogenation opening cabin door state information. The pyroelectric sensor is connected with the control unit and outputs change information of a human body infrared signal at a hydrogenation opening. The pressure sensor is connected with the control unit and outputs hydrogen pressure information in a hydrogen storage container. The control unit is connected with the hydrogenation opening cabin door opening and closing mechanism and outputs control information of the hydrogenation opening cabin door opening andclosing mechanism. The control unit is connected with the feedback module and outputs the hydrogenation opening cabin door state and the change information of the human body infrared signal at the hydrogenation opening. According to the hydrogen fuel automobile hydrogenation monitoring system and the monitoring method thereof, a driver can monitor the hydrogenation process and the hydrogenation opening cabin door state in a cab, and the cumbersome inspection process is simplified while potential safety hazards are avoided.

Description

technical field [0001] The present invention relates to a technology in the field of automobile engineering, in particular to a hydrogenation monitoring system for a hydrogen fuel vehicle and a monitoring method thereof. Background technique [0002] The automobile industry is in the stage of transition from traditional internal combustion engines to new energy sources. The current new energy models are mainly hybrid models and pure electric models. However, the battery life and charging time of pure electric vehicles limit its popularization and application. Hydrogen fuel vehicles have a good performance. It only takes 3 to 5 minutes to fill up hydrogen fuel at a time, and the battery life can reach 800 kilometers. [0003] At present, the structure of the refueling port in fuel vehicles is difficult to apply to hydrogen fuel vehicles. For the hydrogenation of hydrogen fuel vehicles, the following problems need to be solved: [0004] 1) Monitoring of the opening and closi...

Problems solved by technology

In this case, if the hydrogen refueling port door assembly does not have the hydrogen refueling signal reminder function, then the driver in the cab cannot determine whether the hydrogen refueling operation has been performed after the hydrogen refueling door is opened, and also cannot monitor the The status information of the hydrogen supply system during the hydrogenation process, there may be certain safety hazards if the status monitoring of the hydrogen storage and supply system is not carried out during the hydrogenation process
