DETECTION APPARATUS AND METHOD FOR DC POWER SOURCE GROUNDING

摘要

PURPOSE: A DC power ground detecting apparatus is provided to be capable of detecting the existence of a ground by checking a plurality of points of contact in a short time. CONSTITUTION: The fourth connector(27-4) interconnects an interface unit so as to be extended, and the third connector(27-3) is connected to a data conversion box. The first connector(27-1) makes a sensor(10) for detecting a ground to be connected to eight channels. A central processing unit(21) receives a detection signal through the first connector(27-1) and converts the received detection signal through an amplifier(25) and an analog-to-digital converter(21-1). An address controller(22) directs the central processing unit(21) so as to be operated. An amplifier(24-1) amplifies scanning data of the central processing unit(21) to apply the amplified scanning data to the data conversion box through the third connector(27-3). The second connector(27-2) interconnects the central processing unit(21) and the amplifier(24-1).
