The utility model provides an intelligent on-line monitoring device for grounding resistance, which belongs to the technical field of power distribution network detection and comprises an acquisition monitor, a first controller and a power supply. The acquisition monitor comprises a main body, the main body is internally provided with a current collector and a voltage collector which are used for collecting the current information and the voltage information of the ground resistor of the transformer area, the current collector is an open-close type current collector, and the voltage collector is an open-close type voltage collector. And a communication module and a display screen for displaying current information and voltage information of the grounding resistor are also arranged in the main body. The first controller is electrically connected with the communication module, and the power supply supplies power to the acquisition monitor. According to the monitoring device, current and voltage information is c
