The invention provides a ground control for preventing electric blocking and a method. The ground control for preventing electric blocking comprises a hand-held intelligent device, a wireless adapter, an on-post intelligent switch controller, an on-post switch device, a switch state detection module and an identification code. The switch state detection module is arranged on the on-post switch device; the signal input terminal of the switch state detection module is electrically connected to the on-post switch device; the signal output terminal of the switch state detection module is electrically connected to the on-post switch intelligent controller; and the identification code is identified through the hand-held device. The invention can maximally give full play to the advantages of the switch on the intelligentized on-post switch and the control system, realizes an one-to-many ground remote controller and the communication mode of the on-post switch, solves the misoperation caused by the fact that the electric block system cannot perform force blocking on the on-post switch, realizes the non-contact operation intelligent force blocking on the intelligent on-post switch, improves the on-site operation maintenance efficiency, and improves the safety, stability and reliability of the device.
