摘要： Methods, systems, and apparatus are provided for adding functionality to a metering device. A metering device may include a microcontroller (MCU) having separate blocks of memory for storing different types of data. The MCU may store main program code as firmware in one block of the flash memory, while also storing a virtual option board as firmware in a separate block of flash memory. The main program code may be used by the metering device to implement a base level of functionality in the metering device. The virtual option board may be used by the metering device to implement additional functionality. The functionality added by the virtual option board may include customer-specific metering operations and/or market-specific metering operations.

摘要： A metering device may be configured to communicate with other devices on a plurality of metering communication networks. To enable such communications across various networks, the metering communication device may use an active utility identifier corresponding to the metering network in which it is actively communicating. The active utility identifier may be changed to a valid utility identifier corresponding to another metering network and which may be associated with the metering communication device itself. The metering communication device may use the changed active utility identifier to communicate with other devices on the other metering network having the valid utility identifier. For example, the metering communication device may change the active utility identifier to enable communication a test network from a production network, a production network to a test network, or a first test network to a second test network.

摘要： A wireless mesh network, method, and processor-readable storage medium for maintaining both a primary communication path and an alternative communication path for a communication node are disclosed herein. A control node determines an alternative communication path for each node in communication with the control node and stores, for each node, primary communication path information and alternative communication path information. By maintaining both primary and alternative communication path information, the control node can switch from the primary path to the alternative path when a failure in the primary path is detected. Because the control node determines and stores information relating to the alternative path before the failure occurs, switching from the primary path to the alternative path involves little, if any, delay.

摘要： A wireless mesh network and a method operating a wireless mesh network is disclosed. The wireless mesh network comprises: a central node; and a plurality of bidirectional nodes in bidirectional wireless communication with the central node. The central node comprises a transceiver configured to transmit and receive data communications using selected frequency channels of a plurality of frequency channels. The plurality of bidirectional nodes is in bidirectional wireless communication with the central node where each bidirectional node has a respective wireless communication path to the central node that is either a direct path or an indirect path through one or more intermediate bidirectional nodes serving as repeater nodes. Each bidirectional node is characterized by a number of intermediate bidirectional nodes forming a respective wireless communication path to the central node. The central node initiates a first data communication comprising a preamble from the central node to a first bidirectional node of the plurality of bidirectional nodes using a first frequency channel selected from the plurality of frequency channels and sets a receive frequency of the transceiver of the central node to a second frequency channel selected from the plurality of frequency channels. In response to the first bidirectional node receiving the first data communication, the first bidirectional node transmits an acknowledgement message to the central node using the second frequency channel. The central node retransmits the first data communication to the first bidirectional node using the second frequency channel in response to the central node failing to receive the acknowledgement message within a defined time limit.

摘要： Puede usarse una clave primaria en un primer intento, por un nodo remoto, de desencriptar mensajes entrantes provenientes desde un nodo maestro. Si el intento de desencriptar falla en el nodo remoto, una clave secundaria puede entonces ser usada para intentar desencriptar el mensaje. Inicialmente, las claves primaria y secundaria pueden ser las mismas. Una herramienta de campo, tal como una unidad de programación sostenida manualmente, operada por un técnico en el sitio de un nodo remoto puede cambiar la clave secundaria pero no puede causar ningún cambio en la clave primaria. La clave secundaria puede permanecer cambiada hasta que una nueva clave primaria es verificada y/o autenticada y la clave secundaria es sobre-escrita con la nueva clave primaria. La clave primaria puede ser cambiada/establecida solamente por el nodo maestro por medio de un requerimiento encriptado. Un técnico no puede usar una herramienta de campo para cambiar la clave primaria.

摘要： A primary key may be used for a first attempt by a remote node to decrypt incoming messages from a master. In the event the decrypt attempt fails at the remote node, a secondary key may then be used to attempt to decrypt the message. Initially, the primary and secondary keys may be the same. A field tool, such as a hand-held programming unit operated by a technician at a remote node location, may change the secondary key, but may not cause any change to the primary key. The secondary key may remain so changed until a new primary key is verified and/or authenticated and the secondary key is overwritten with the new primary key. The primary key may only be changed/set by the master via an encrypted request. A technician may not use a field tool to change a primary key. IA/flu I co 0 U-) o W 0)

摘要： Se describe en la presente un método, red de malla inalámbrica y medio de almacenamiento que se puede leer por procesador para promover una comunicación de extremo a extremo exitosa en una red de malla escrutinada en tanto que se mejora el rendimiento del sistema. Las comunicaciones exitosas son reconocidas a cada nivel de salto para reducir la necesidad de duplicar paquetes por redundancia. De esta manera, si un primer nodo bidireccional transmite un paquete a un segundo nodo bidireccional, el segundo nodo bidireccional reconoce el paquete y primer nodo bidireccional recibe el acuse, luego, el primer nodo bidireccional no necesita enviar un paquete duplicado.

摘要： An electricity meter comprises a processor 305', a memory 312', a communication interface 306'/316, and at least one disconnect switch or relay 340 for disconnecting a load from the meter. The disconnect switch 340 can be changed between open and closed states, controlled by the processor 305', provided that a safety interlock flag stored in memory 312' permits disconnecting or reconnecting the load. The safety interlock flag can prevent disconnection of the load e.g. when the load is essential and must not be cut off from its electricity supply, or can prevent reconnection of the electricity supply e.g. when maintenance is taking place. An auxiliary relay 360 may be provided to supply power to another device and may be switched according to a separate flag in the memory. A rights management table may also be used to determine if the request to change the state of the switch or relay is from an authorized source, with unauthorized requests not allowed to change the state of the switch.
