The present application relates to a protection and control system for an intelligent substation based on an industrial Internet architecture. The intelligent substation changes a decentralized modeling manner of firstly adding physical apparatuses and then adding functions of the apparatuses in a traditional substation, but adopts a centralized modeling manner of adding all of protection, measurement and control, exchange and telecontrol functions in substation configuration descriptions by taking the whole substation as a modeling object. The intelligent substation changes an operating mode of accessing merging unit and intelligent terminal integrated devices to different physical apparatuses to realize measurement and control and various protections respectively in the traditional substation, while the intelligent power server collects process level data in real time through an embedded high-bandwidth switched communication network and performs real-time data processing on the collected process level data, thereby realizing all the protection and measurement and control over primary devices.

Method and apparatus are disclosed for energy-consumption detection of vehicles in an off state. An example vehicle includes a controller area network (CAN) including CAN buses, a gateway module, and electronic control units (ECUs) that are each connected to one of the CAN buses. Upon activating while the vehicle is in an off state, a first of the ECUs sends a message via a corresponding one of the CAN buses to activate the gateway module. The message includes activation data and the gateway module stores the activation data.

A control system 9 according to the present invention is mounted on a moving object. The control system 9 includes: an observing device 92 which transmits observation result data indicating an observation result of surroundings of the moving object; a first control instruction device 91 which transmits first control data indicating the control contents determined based on the observation result data; a movement control device 93 which controls movement of the moving object; and a relay device 95 which relays the first control data transmitted from the first control instruction device 91, to the movement control device 93. When a second control instruction device 94 which transmits second control data indicating the control contents determined based on the observation result data is provided to the control system 9, the relay device 95 transmits the second control data instead of the first control data, to the movement control device 93.

A method for operating at least one node connected to a shared communication medium reduces or eliminates the ability of an adversary node to identify the at least one node based on transient signal characteristics of a signal that the at least one node generates when transmitting a bit through the shared communication medium. The method includes adjusting, with a controller in a first node, an impedance of a variable impedance circuit in the first node to a first impedance level that the controller determines randomly, the variable impedance circuit in the first node being connected to an output of a transceiver in the first node and to a shared communication medium, and transmitting, with the transceiver, a first data bit through the shared communication medium with the variable impedance circuit producing the first impedance level.

In an embodiment, yield data representing yields of crops that have been harvested from an agricultural field and field characteristics data representing characteristics of the agricultural field is received and used to determine a plurality of management zone delineation options. Each option, of the plurality of management zone delineation options, comprises zone layout data for an option. The plurality of management zone delineation options is determined by: determining a plurality of count values for a management class count; generating, for each count value, a management delineation option by clustering the yield data from and the field characteristics data, assigning zones to clusters, and including the zones in a management zone delineation option. One or more options from the plurality of management zone delineation options are selected and used to determine one or more planting plans. A graphical representation of the options and the planting plans is displayed for a user.

An electric motor addressing system and method for an agricultural implement receives, at an electronic control unit (ECU), an address claim request from each motor of a plurality of motors coupled to the ECU via a first bus. Each address claim request includes a requested bus address and a binary value corresponding to a pin connector setting associated with a harness connector of the respective motor. The system associates the binary value with a physical address for each motor without reference to the bus address and maps each bus address to the physical address.
