The first loop and the second loop are arranged in parallel, so that the signal connection device 100 can still work normally when one of the first loop or the second loop is damaged, and the situations of missing report or no response are avoided.
The first dynamic break contact switch 222 of the second relay 22 is connected in series on the first loop, the second dynamic break contact switch 223 of the second relay 22 is connected in series on the second loop, the first relay 21 and the second relay 22 are connected with the linkage switch 22, and the first relay 21 and the second relay 22 are mutually staggered and linked under the control of the linkage switch 22. The interlocking means that the first relay 21 and the second relay 22 are alternately opened or closed.
Specifically, when the ganged switch 22 is in a non-operating state, i.e., a natural state, the contact switch of the second relay 22 is in a power-on state, and the first relay 21 is in a power-off state; when the interlock switch 22 is switched to the operating state, the first relay 21 is in the closed energized state, and the second relay 22 is switched to the deenergized state.
