This application relates to an inverter in a power generation system. The inverter is configured to convert a direct current that is input from a direct-current-side device into an alternating current for power supply. The inverter includes a control apparatus and a communications apparatus. The control apparatus is configured to control the inverter to convert the direct current that is input from the direct-current-side device into an alternating current for power supply. The communications apparatus is coupled to the control apparatus, and is configured to send a networking information request signal used to request networking information to the direct-current-side device in the power generation system through a direct-current power line, where a frequency of the networking information request signal is within a first frequency band; receive the networking information from the direct-current-side device; and send a control signal to the direct-current-side device, where a frequency of the control signal is within a second frequency band. The control signal is used to control an operating parameter of the direct-current-side device. The first frequency band is lower than the second frequency band. This application can effectively prevent crosstalk during networking between the inverter and the direct-current-side device. In addition, this application further relates to a communications apparatus, a direct-current-side device, and a power generation system.

"Method and system for communication in a space launcher and space launcher equipped with it" Method for communication in a space launcher, between an on-board computer (3) and a plurality of on-board equipment including a plurality of sensors (6), a plurality of actuators (7) and a plurality of control units (8, 9) of critical subsystems of said launcher, said launcher further comprising an electrical energy storage unit (5) provided for electrically powering said on-board equipment (6, 7, 8, 9).

For reliable, fail-safe locking monitoring of a closing device (5) of a vehicle (4) of a cableway (1), an electrical connection is established between a vehicle power line modem (15) on the vehicle (4) and a station power line modem (16, 16') via a busbar (10, 10') contacted by the vehicle's current collector (11) in the station (2), the station power line modem being connected to a cableway controller (13), and the locking state of the locking unit (7) being transmitted from the vehicle (4) to the cableway controller (13) via this connection by means of power line communication, wherein in the event of an erroneous locking the vehicle (4) stops in the station (2) in the area of ​​the busbar (10, 10') and the locking state is again transmitted to the cableway controller (13) when the vehicle (4) is stationary.

For reliable, failsafe monitoring of the locking of a closure device of a vehicle of a cableway is disclosed in which provision is made for an electrical connection to be established between a vehicle powerline modem on the vehicle and a station powerline modem, which is connected to the cableway controller, via a busbar in the station, with which contact is made by a current collector of the vehicle, and for the locking status of a locking unit to be transmitted from the vehicle to the cableway controller via this connection by means of powerline communication, wherein, in the event of defective locking, the vehicle is stopped in the region of a busbar in the station and the locking status is transmitted to the cableway controller again when the vehicle is at a standstill.

Systems and methods for setting a carrier-sensing mechanism in a PLC node are disclosed. In a PLC standard, coexistence is achieved by having the nodes detect a common preamble and backing off by a Coexistence InterFrame Space (cEIFS) time period to help the node to avoid interfering with the other technologies. In one embodiment, a PHY primitive is sent from the PHY to the MAC know that there has been a preamble detection. A two-level indication may be used—one indication after receiving the preamble and other indication after decoding the entire frame. The MAC sets the carrier-sensing mechanism based on the preamble detection.
