The main control panel overhauls/the input signal of automatic signal input end is invalid, and the elevator enters the urgent electronic or overhauls the mode of the state.
When the elevator is in a car roof ascending maintenance state, a first pole switch of the two-pole switch is closed, a second pole switch is opened, a fifth key switch is switched on at the same time, an electric signal output by the high-frequency electric signal input end sequentially passes through the first pole switch, the fourth key switch, the fifth key switch, the third reverse diode and the third dial switch of the two-pole switch, and an electric signal is output to the alarm module through the third twelve jacks to enable the alarm module to operate; when the elevator is in a down maintenance state on the car roof, the first pole switch of the two-pole switch is closed, the second pole switch is disconnected, the sixth key switch is switched on, the electric signal output by the high-frequency electric signal input end sequentially passes through the first pole switch, the fourth key switch, the sixth key switch, the fourth reverse diode and the third dial switch of the two-pole switch, and the electric signal is output to the alarm module through the third twelve jacks, so that the alarm module operates.
When the elevator is in an emergency ascending electric state, a first pole switch of the second-stage switch is switched off, a second pole switch is switched on, a first pole switch and a third pole switch of the third pole switch are switched on, a second pole switch is switched off, the first key switch and the second key switch are switched on, electric signals output by the high-frequency signal input end sequentially pass through the second pole switch of the second-stage switch, the first dial switch, the third pole switch of the third pole switch, the first key switch, the second key switch, the third reverse diode and the third dial switch, and are output to the alarm module through a twelfth jack, so that the alarm module operates; when the elevator is in the urgent down electric state, the first pole switch disconnection of second grade switch, the second pole switch is closed, the first and third pole switch closure of tripolar switch, the second pole switch disconnection, switch on first and third key switch, the signal of telecommunication of high electric frequency signal input output passes through the second pole switch of two pole switch in proper order, first dial switch, the third pole switch of tripolar switch, first key switch, third key switch, fourth reverse diode and third dial switch, export the signal of telecommunication through the twelfth jack of third and give alarm module, make alarm module operation.
The function of audible and visual alarm can be realized through two modes, and under the communication loop mode, the switching on the function can be realized only by inserting different switch states of all dial switches and bypass modules into different connectors, so that the effect of multiple functions of one port is achieved, the cost is reduced, and the space layout of the elevator control cabinet is optimized. Under the signal return circuit mode, just can realize examining and repairing the warning effect of audible and visual annunciator when operation or emergency operation under need not to get into the bypass state, make the maintenance personal meet except that the problem of elevator door lock class etc. outside, elevator cab examines and repair operation or the emergent electronic operation of this computer lab, audible and visual annunciator also can normally work.
