In the contact network maintenance, it can ensure the normal connection of the grounding wire, and timely dismantling is the primary prerequisite for ensuring the safety of maintenance personnel and equipment. In this paper, an on-line detection device for grounding wire working state based on GPRS technology is designed. The photoelectric switch and video image are used to collect the working state of the grounding wire. The SIM300 module is used to transmit different state information of the grounding wire to the dispatching center. The system software and hardware design is completed, and finally the ground line working state image data and short message transmission are effectively realized.
