3. the method of claim 1, wherein the first controllable switch and the second controllable switch are closed when the induced current detected by any one of the induced current measuring devices of the left foot and the right foot is greater than 100 ma. Through the mode that the serial circuit of the belt head, the controllable switch I, the controllable switch II, the metal conducting part I and the metal conducting part II is closed, equipotential is formed between the left foot and the right foot of an operator, and the operator is prevented from being damaged by step voltage under the condition that the insulation shoes are aged and broken down.
4. The method of claim 1, wherein the work registration device is a ball control device currently used in the power industry for remote violation inspection, has the functions of registering work time, work place and work content, and can adopt communication modes such as 4G and Bluetooth.
