Abstract
The utility model relates to a network-based ground wire monitor. The monitor comprises an input network, an alarm resistance setting unit, a display unit, an analog-to-digital conversion unit, a central processing unit and a network interface unit. One end of the input network is connected to a monitoring connection point for real-time monitoring grounding resistance. The alarm resistance setting unit is used for setting alarm resistance. The display unit is used for displaying the monitored grounding resistance. The analog-to-digital conversion unit is connected with the input network, the alarm resistance setting unit and the display unit, and used for performing analog-to-digital conversion. The central processing unit is connected with the analog-to-digital conversion unit, and compares the grounding resistance of the monitoring connection point transmitted by the analog-to-digital conversion unit with the alarm resistance so as to determine whether to give a warning. The network interface unit is connected with the central processing unit, and used for transmitting the monitored grounding resistance to a corresponding host computer. According to the utility model, by using the analog-to-digital conversion technology and resistance network principles, the network-based ground wire monitor monitors the grounding of equipment, and is capable of real-time monitoring the grounding state of the ground wire and uploading the monitoring information to the host computer in real-time.
