    摘要: A communication system, includes a trailer bridge disposed on a cargo trailer, the trailer bridge comprising a power line transceiver for communicating with a tractor module when the trailer and a tractor having the tractor module are electrically connected; and a locator module for communicating with the trailer bridge, the locator module comprising a mobile or cellular transceiver for communicating with a mobile or cellular communications network external to the trailer. The locator module is to communicate making of the electrical connection between the trailer and tractor to a remote datacenter of an owner/operator of the trailer in response to a signal from the trailer bridge indicating that the electrical connection has been made.

    摘要: A system (e.g., a power and communication system for remote components) can include a first wire, a second wire, and a first module operatively connected to the first and second wire. The first module can be configured to output power to and to communicate over the first wire and second wire. The system can include a second module operatively connected to the first module by the first wire and the second wire. The second module can be configured to receive power from the first module and to communicate with the first module over the first wire and/or second wire. The first module can be configured to modify a voltage on at least the first wire to signal to the second module to provide serial communication to the first module via the first wire and/or second wire.

    摘要: A signal transmission device includes a signal side electrode; a first signal line connected to one side of the signal side electrode; a second signal line connected to the other side of the signal side electrode; a power source side electrode that forms a pair with the signal side electrode and is connected to the signal side electrode via an electronic component including at least an inductor component; and a capacitive coupling part that capacitively couples the power source side electrode to a ground wiring or a power source wiring. The first signal line, the signal side electrode, and the second signal line form a transmission path for transmitting an electric signal. The first signal line and the second signal line transmit power via the signal side electrode, the electronic component, and the power source side electrode.

    摘要: Described herein are embodiments for dual-port communication and power delivery for one-wire applications. Embodiments of one-wire bridge devices are disclosed to provide a dual-port link for two one-wire masters to communicate with one another in a multi-voltage system while intermittently allowing charging voltage. The configuration may be used to set a bidirectional pass through mode that allows level shifted fast logic signals to pass through the two one-wire links. A timer may also be configurable to time-out the pass through mode from edge in-activity. Power may be derived for operation directly from one of the links, eliminating the need for an external power supply when local power is not available. When local power is available, the other one-wire link provides local access and the pass through mode. Such configurations make it easy for a two-contact solution to be both a communication channel and a power supply for battery charging.

    摘要: The technology provides for a power line communication system capable of providing data from a first device to a second device over a power line. The first device may include a set of contacts and a second device may include a second set of contacts. The second set of contacts may be adapted to electronically engage with the first set of contacts of the first device to form at least a power and ground lines connection. Circuitry within the first device and the second device may include circuitry for providing data over the power line connection between the first device and the second device. The circuitry may comprise a power line, a ground line, a transmitter line carrying data signals, a capacitor coupling the transmitter line to the power line at a connection point, and a receiver comprising two field effect transistors.

    摘要: Provided is a zero crossing point signal output method, including: continuously receiving zero crossing point square wave signals, and periodically sampling zero crossing point square wave signals at a predetermined sampling frequency; acquiring sampling numbers of 1st to Mth zero crossing point square wave signals to obtain an average sampling number S, and calculating a first zero crossing point interval T1; setting a zero crossing point signal output interval as the first zero crossing point interval T1; continuously outputting zero crossing point signals with an interval being the zero crossing point signal output interval; obtaining sampling numbers of M+1th to M+Nth zero crossing point square wave signals, calculating a difference value between each of the sampling numbers and S, and obtaining an accumulated difference value Δs through calculation; when Δs is not within a predetermined change range, obtaining a second zero crossing point interval T2 and setting the zero crossing point signal output interval as T2; and when Δs is within the predetermined change range, keeping the zero crossing point signal output interval unchanged.
