A system for managing an industrial workflow including a plurality of asset tags, each tag associated with a corresponding asset, and a plurality of point of interest reader nodes, each reader node including at least one BLE radio in communication with a subset of the plurality of asset tags and a communications manager in communication with at least one cloud server. The system further includes a cloud server having a location services module, a process and workflow editor configured to enable a user to access a plurality of rules in a process flow library regarding how different types of assets are expected to move through a facility, and a real-time compute engine configured to generate a sequence of events for an asset and interpret the process and workflow plan to determine whether a trigger event has occurred.

System for managing an industrial workflow

A system for managing data related to at least one leaf node device, the system including a location processing engine located on a server that is remote from the at least one leaf node device; at least one point of interest (POI) device for collecting data relating to at least one leaf node device and transmitting the collected data with a timestamp using Bluetooth Low Energy (BLE); at least one reader node device for receiving the collected data from the point of interest (POI) device using BLE and transmitting the collected data to the location processing engine; and a database of the known locations of POI devices, wherein the known locations are used as a basis for determining the location of the at least one leaf node device that communicated with the POI device.

Asset location and management system with distributed processing

An asset location and management system, the system including multiple reader nodes, each reader node having a Bluetooth Low Energy (BLE) radio in communication with a plurality of peripheral devices, a local service module and a communications manager in communication with a cloud server. The system further including the cloud server having a communication module, a process flow library to describe how peripheral devices are expected to move through a facility, a rules library describing trigger events associated with one or more peripheral device and identifying a corresponding action for each trigger event, and a real-time compute engine to generate a sequence of events based on the data from the peripheral devices and the process flow library.

Events based asset location and management system

A system for managing data related to at least one leaf node device includes a location processing engine located on a server that is remote from the leaf node device, at least one point of interest (POI) device for collecting data via Bluetooth Low Energy (BLE) communication signals from the leaf node device on each of a plurality of channels and transmitting the collected data which includes phase angle information, a reader node device for receiving and transmitting the collected data to the location processing engine and a database of the known locations of a plurality of POI devices. The reader device or the location processing engine averages the collected data across the plurality of channels, and the known locations are used along with the averaged data as a basis for determining the location of the leaf node device.

A method and apparatus for alignment of TDM-based signals for packet transmission using framed and unframed operations are described. In an embodiment, a line card in a network element includes a deframer unit that receives a Time Division Multiplexing (TDM) signal. The TDM signal includes a payload and overhead data. The deframer generates frame alignment data based on the overhead data. The line card also includes a packet engine unit coupled to the deframer unit. The packet engine unit receives the payload, the overhead data and the frame alignment data and generates a number of packet engine packets. The packet engine packets represent a frame within the TDM signal such that the packet engine packets include the payload, the overhead data and the frame alignment data. Additionally, the line card includes packet processor coupled to the deframer unit. The packet processor receives the packet engine packets and generates network packets based on the packet engine packets.
