A detection system includes a first sensor coupled to a pipe associated with a pump and generates temperature data associated with a temperature of the pipe. The system includes a second sensor positioned within an acoustic sensing distance from the pump and that generates sound data associated with a sound of the pump. The system includes a processing device configured to execute data instructions to store a baseline temperature signature and a baseline acoustic signature, and receive the temperature data from the first sensor and the sound data from the second sensor. The processing device is configured to, based on (1) a determination that flow through the pipe is reduced by comparing temperature data to the baseline temperature signature, and (2) a determination that the pump remains operational based on comparing the acoustic data to the baseline acoustic signature, generate an indication that the pipe is blocked.

Reducing false alarms with multi-modal sensing for pipeline blockage

An apparatus and a method for use in controlling the apparatus are disclosed. The apparatus includes a purified hydrogen generator; at least one of a compression unit, a storage unit, and a dispensing unit; and a system controller. The system controller is capable of monitoring the operation of the hydrogen generator and the compression unit, storage unit, or dispensing unit at a system level and shutting down at least one of hydrogen generator and the compression unit, storage unit, or dispensing unit upon the detection of a dangerous condition. The method includes monitoring the generation of a purified hydrogen stream from a system level; monitoring the at least one of a compression, a storage, and a dispensing of the purified hydrogen gas stream from the system level in concert with monitoring the purified hydrogen gas stream generation; and shutting down at least one of the purified hydrogen gas stream generation and the compression, the storage, or the dispensing upon the detection of a dangerous condition at the system level.
