The utility model discloses a
direct current electric leakage intelligent alarm terminal for
industrial equipment, comprising an alarm terminal body, a
microprocessor is integrated in the alarm terminal body, the
microprocessor is connected with a detection circuit and an alarm circuit, the
microprocessor is used for
processing and analyzing digital signals and determining whether
direct current electric leakage exists, and the alarm circuit is connected with the detection circuit and the alarm circuit. After electric leakage is determined, the alarm circuit is controlled to give an alarm; the detection circuit comprises a
direct current voltage acquisition module, a direct current acquisition module, a
signal amplification module, an A / D conversion module and a filtering module, the alarm circuit comprises a
buzzer, an LED alarm lamp, a
wireless communication module and a voice broadcast module, when the microprocessor judges that direct
current electric leakage exists, the microprocessor controls the
buzzer and the LED alarm lamp to send out alarm signals, and the voice broadcast module broadcasts the alarm signals. The microprocessor is connected with the
wireless communication module, alarm information is transmitted to an upper computer through the
wireless communication module, and the voice broadcast module is controlled to carry out voice alarm when the microprocessor judges that direct-
current electric leakage exists.
