摘要： A utility meter has a multiprocessor architecture including (i) a microprocessing unit (MPU) for executing multiple software applications and (ii) another processing unit for performing core metrology functions in real time. For instance, the utility meter includes a metrology engine, an MPU, and one or more metrology applications. The metrology engine measures consumption of a resource and generates consumption data based on the consumption of the resource. The metrology engine includes a metrology processor, a dedicated memory, and a real-time operating system run by the metrology processor to enable the metrology engine to run time-critical metrology functions in real time. The MPU is coupled to the metrology processor and includes one or more processor cores. The MPU runs the one or more metrology applications over a primary operating system of the MPU, and the one or more metrology applications utilize the consumption data.

摘要： Systems and methods are disclosed for detecting node outages in a mesh network. A tracking node in the mesh network detects a set of signals originating from a tracked node in the mesh network. The set of signals includes beacons and communication messages transmitted by the tracked node. The tracking node determines that a threshold number of the alive beacon intervals have passed since receiving a most recent signal from the tracked node. The tracking node then outputs a ping to the tracked node requesting a response to the ping. When the response to the ping is not received from the tracked node, the tracking node transmits an outage alarm message to a next topologically higher layer of the mesh network, the outage alarm message comprising an identification of the tracked node.

摘要： Systems and methods are disclosed for providing scheduled communication between a primary network, such as a time synchronized channel hopping (“TSCH”) network, and a secondary network, such as a carrier sense multiple access (“CSMA”) network. During a first selected slot-offset in a TSCH hopping pattern, a gateway node communicates with a primary network node. During a second selected slot-offset in the TSCH hopping pattern, the gateway node communicates with a secondary network node. A communication schedule identifies the source and destination nodes and channel frequency for each slot-offset. The communication schedule is set such that the CSMA wake-up period for the secondary network is synchronized with the second slot-offset in the TSCH hopping pattern.

摘要： Systems and methods are disclosed for detecting node outages in a mesh network. A tracking node in the mesh network detects a set of signals originating from a tracked node in the mesh network. The set of signals includes beacons or communication messages transmitted by the tracked node. The tracking node determines that a threshold number of the beacon intervals have passed since receiving the most recent signal from the tracked node. The tracking node performs outage validation based on data received from another node in the mesh network and updates the status of the tracked node. Based on the updated status, the tracking node outputs a ping to the tracked node requesting a response to the ping. When the response to the ping is not received from the tracked node, the tracking node transmits an outage alarm message to a next topologically higher layer of the mesh network.

摘要： A service node performs computational tasks or other operations on behalf of a meter or other network device. A meter may collect data regarding electric parameters associated with an electric distribution network. When analysis of the collected data is required, the meter may determine that it requires the resources of a service node. The meter may send a request to a directory node to identify a service node or it may send a request seeking a service node. The service node performs the analysis and sends the results of the analysis back to the meter. The service nodes supports the dynamic distributed processing of analytic services.

摘要： Detecting an outage by a first node in layer N of a multi-layer mesh network that is in communication with a root node via the mesh network. After waiting for a sustained outage period that expires, the first node waits for a layer-specific time interval that is based on a topology of the second layer. The first node receives a last gasp from a second node in layer N+1 of the multi-layer mesh network. The last gasp includes an identifier for the second node and an indication of layer N+1. After the layer-specific time interval expires, the first node transmits a consolidated last gasp that includes an identifier for the first node, an indication of layer N, the identifier for the second node, and the indication of layer N+1.
