    摘要： A system includes a plurality of controllers associated with the plurality of units of building equipment, each controller comprising a plurality of communication ports, a plurality of cables connected to the plurality of communication ports and linking together the plurality of controllers, wherein the plurality of controllers are configured to self-identify a break in a connection between two the plurality of controllers by monitoring statuses of the plurality of communication ports. The system also includes circuitry configured to receive a signal indicative of the order of the connections between the plurality of controllers from the plurality of controllers, generate a graphical map of the order of the connections between the plurality of controllers based on the signal, receive, from the plurality of controllers, an indication of a break in a connection between two of the plurality of controllers, and update the graphical map to indicate the connection as broken.

    摘要： A detection apparatus according to the present disclosure includes a signal output unit configured to output a measurement signal that includes a component having a first frequency to a transmission line, a signal measurement unit configured to measure a response signal, from the transmission line, to the measurement signal output from the signal output unit and a processing unit configured to generate a difference signal that is a difference between the response signal measured by the signal measurement unit and a reference signal that is based on the measurement signal, calculate an index value that indicates a strength of a correlation between the reference signal and the difference signal, and detect an abnormality in the transmission line on the basis of the calculated index value.

    摘要： According to an aspect of an embodiment, a method may include obtaining a first signal at a first port of a communication system. The first signal may include a combination of an incident signal and a reflected signal. The method may include performing a first processing to the first signal. In response to the first processing, the method may include performing a second processing to the first signal. The method may include estimating a voltage standing wave ratio (VSWR) associated with a transmission line from results of the second processing to the first signal.
