The embodiment of the invention discloses a monitoring system and method for a gas storage cylinder and a fuel cell vehicle. The monitoring system comprises the gas storage cylinder, at least one sound sensor installed on the gas storage cylinder and a controller electrically connected with the sound sensor. The sound sensor is used for collecting sound signals generated by the gas storage bottle and sending the sound signals to the controller; and the controller is used for processing and analyzing the received sound signal to obtain a Mel-frequency cepstrum coefficient, comparing the Mel-frequency cepstrum coefficient with a preset threshold range, and carrying out early warning prompt when the gas storage cylinder is judged to be abnormal. According to the technical scheme provided by the embodiment of the invention, the gas storage bottle is monitored in real time, and the safety and reliability of the gas storage bottle are improved.
本发明实施例公开了一种储气瓶的监测系统、方法及燃料电池汽车,包括储气瓶、安装在储气瓶上的至少一个声音传感器、以及与声音传感器电连接的控制器;声音传感器,用于采集储气瓶产生的声音信号,并发送至控制器;控制器,用于根据接收到的声音信号进行处理分析得到梅尔频率倒谱系数,将梅尔频率倒谱系数与预设阈值范围进行比较,并在判定储气瓶异常时进行预警提示。本发明实施例提供的技术方案,以实现对储气瓶实时监测,提高储气瓶的安全性以及可靠性。
