摘要： Proposed is a warning system which includes: a warning device; a display device; an IC CPU for controlling the operation of the display device and the warning device; and a master ECU for, connected to the IC CPU through a communication channel and connected to one or more warning devices through a hardware channel, controlling the operation of the warning device through the IC CPU. The master ECU includes an error detection module to monitor regularly the data validity of the communication channel, the warning device and the response of the IC CPU, and an on/off module to operate the warning device. When the error detection module detects an error in the data validity of the communication channel, the warning device and the response of the IC CPU, the master ECU controls the on/off module to operate directly the warning device using the hardware channel.

摘要： The invention relates to a method for detecting arcs in a direct-current circuit by means of a detection conductor, which is led at least along a conductor of the direct-current circuit that carries a voltage and is to be monitored. According to the invention, a voltage signal related to a potential of the direct-current circuit is coupled into the detection conductor at an incoupling point via a series resistor, the voltage signal is coupled out at an outcoupling point of the detection conductor, the voltage signal before the series resistor is compared with the voltage signal at the outcoupling point, and an arc is inferred if the voltage signal at the outcoupling point deviates from the voltage signal before the series resistor by more than a specified amount. The invention further relates to a device for carrying out the method. The method and the device enable fast and reliable detection of an arc in a direct-current circuit.
