Further, referring to fig. 2, the switch further includes a second switch rail 500 and a second stock rail 400, the second distance meter 130 is disposed on the second switch rail 500 or the second stock rail 400, and the testing end of the second distance meter 130 is located between the second switch rail 500 and the second stock rail 400, the second distance meter 130 is used for obtaining the distance information between the second switch rail 500 and the second stock rail 400.
In one embodiment, referring to fig. 3 and 4, the switch further comprises a switch machine 600. The switch 600 includes a handle 630, and the switch 600 has a first slot 640 and a second slot 650. A first sensor 140 and a second sensor 150 are each disposed on the switch machine 600, the first sensor 140 being configured to sense a handle 630 located within a first slot 640 and the second sensor 150 being configured to sense a handle 630 located within a second slot 650.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
