A system for monitoring a petrochemical installation is disclosed. The system can include an optical imaging system comprising an array of optical detectors. The system can comprise processing electronics configured to process image data detected by the optical imaging system. The processing electronics can be configured to detect a target species based at least in part on the processed image data. The processing electronics can further be configured to, based on a detected amount of the target species, transmit an alarm notification to an external computing device over a communications network indicating that the target species has been detected at the petrochemical installation.

A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.

Systems, apparatus, and methods detect and respond to environmental anomalies in a shipping container on a transit vehicle having an external transceiver. Systems generally have wireless ID nodes at different locations within the container and a command node mounted to the container. The command node is programmatically adapted to selectively assign a subset of the ID nodes as dedicated monitor beacons deployed within the container, identify an unresponsive group from the assigned subset of the ID nodes monitored to be in an unanticipated state of ceased broadcasting based upon the monitoring step. The command node detects the environmental anomaly when a size of the unresponsive group in the assigned subset of ID nodes exceeds a threshold setting maintained by the command node, automatically generates an alert notification related to the detected environmental anomaly, and initiates a mediation response for the anomaly by transmitting the alert notification to the vehicle's transceiver.

A node-enabled battery system having integrated environmental detection and reporting. The system may have a battery and sensor-based node attached to the battery. The system's sensor-based node has a processor, memory (maintaining a battery monitoring program code and a battery threshold metric value), a wireless communication interface and a sensor operative to sense a battery status condition for the battery. When executing the battery monitoring program code, the processor is programmatically configured and adapted to be operative to receive status data from the sensor reflecting the battery status condition as sensed by the sensor, automatically trigger generation of a layered alert notification related to the battery when the received status data is inconsistent with the battery threshold metric value, and cause the wireless communication interface to broadcast the layered alert notification to initiate a mediation response related to the battery status condition for the battery.

An improved system on a transit vehicle is described for coordinated mediation action in response to an identified environmental anomaly on a shipping container transported by the vehicle. The system has wirelessly broadcasting ID nodes at different locations within the container, and a fire suppression system on the vehicle having a wireless transceiver-based controller operating as a master node that can cause the suppression system to deliver fire suppressant material to the container using a delivery nozzle and pump. The controller, as master node, is configured to operate as a primary monitor for the anomaly by being operative to monitor ID node signals; identify the anomaly based on the signals; generate a layered alert notification related to the anomaly (identifying a targeted mediation action and establishes a mediation response priority); and initiate a mediation response by the suppression system related to the targeted mediation action and the mediation response priority.

A dynamically transitioning system for monitoring a shipping container transported by a transit vehicle for an environmental anomaly has ID nodes within the container (at least some being associated with objects being transported), a command node on the container, and an external master node at a known location on the vehicle. The command node operates as a primary monitor for the anomaly by monitoring signal activity from the ID nodes; identifying the anomaly based upon the signal activity; generating a layered alert notification that identifies a targeted mediation recipient and mediation action, and establishes a mediation response priority; and transmits the notification to an external transceiver on the transit vehicle to initiate a mediation response for the mediation action. The command node dynamically instructs the external master node to temporarily operate as the primary monitor when the command node is within a threshold distance from the external master node's location.
