The step S110, of receiving, by using an acquisition module, the opening and closing position information of the plurality of circuit breaker modules acquired by the plurality of intelligent terminal modules, includes:

And receiving the opening and closing position information of the plurality of breaker modules acquired by the plurality of first intelligent terminals by using the first acquisition device, and receiving the opening and closing position information of the plurality of breaker modules acquired by the plurality of second intelligent terminals by using the second acquisition device.

For example, if the first intelligent terminal 21 overhauls the hard platen input while the first collection device 31 connected thereto overhauls the soft platen input, it is determined that the first collection device 31 is slightly failed; at this time, if the second intelligent terminal 22 overhauls the hard pressing plate to withdraw, and meanwhile, the second acquisition device 32 connected with the second intelligent terminal overhauls the soft pressing plate to withdraw, then the second acquisition device 32 is judged to normally operate without faults; the control host 40 obtains the opening and closing position information of the circuit breaker module 10 from the second collecting device 32. If the first intelligent terminal 21 overhauls the input of the hard pressing plate and the overhauling soft pressing plate of the first acquisition device 31 connected with the input of the hard pressing plate exits, judging that the first acquisition device 31 slightly fails; if the first intelligent terminal 21 overhauls the hard pressing plate to withdraw, and meanwhile, the first acquisition device 31 connected with the first intelligent terminal overhauls the soft pressing plate to input, the first acquisition device 31 is judged to slightly fail.
