System and methods for hydrogen plant condition monitoring using a wireless modular sensor system

A system for monitoring a hydrogen plant, comprising:

• a first mobile wireless hydrogen flame sensor module including:
• a first hydrogen flame sensor configured for detecting a hydrogen flame indicative of a hydrogen leak within the hydrogen plant;
• a first wireless interface configured for transmitting data concerning the hydrogen leak via a wireless network to a second mobile wireless hydrogen flame sensor module when the hydrogen leak is detected by the first hydrogen flame sensor;
• a first drive system including a motor, drive train, and controller that moves the first mobile wireless hydrogen flame sensor module along a surface;
• and
• a first navigation system that controls movement of the first mobile wireless hydrogen flame sensor module;
• and
• the second mobile wireless hydrogen flame sensor module including:
• a second hydrogen flame sensor;
• a second wireless interface configured for transmitting the data concerning the hydrogen leak via the wireless network to a remote station when the hydrogen leak is detected by the first hydrogen flame sensor;
• a second drive system including a motor, drive train, and controller that moves the second mobile wireless hydrogen flame sensor module along the surface;
• and
• a second navigation system that controls movement of the second mobile wireless hydrogen flame sensor module;
• wherein the first mobile wireless hydrogen flame sensor module is movable by the first drive system beyond a wireless communication range of the remote station in response to communication from the remote station through the second wireless interface and the first wireless interface.
