In step 3, control part 15 is according to the signal that comes self- hold circuit 21a, 21b, confirm that escalator 1 is in rising, in the decline or stops, if for stopping then being judged as and stopping, return step 2, if imported rising signals or dropping signal, then be judged as escalator 1 for starting, enter step 4.
In step 4, control part 15 carries out the action checking of safety sensor 7.That is, judge whether to have imported respectively from safety sensor 7-1,7-2 ..., 7-n the pick-off signal of each contact, if imported pick-off signal, then be judged as this safety sensor 7 actions.
In step 5, control part 15 is that even when having the action of a safety sensor 7 (when having the input of pick-off signal under off condition), enter step 6, (during Continuity signal) do not return step 2 when having the action of safety sensor 7.
In step 6, control part 15 keeps faulty condition, in step 7, has generated and imported the safety sensor 7 cooresponding intrinsic recognition data of pick-off signal.For example, if if be predetermined safety sensor 7-1 action then be 1 safety sensor 7-2 action then be 2 etc. intrinsic recognition data, and will this intrinsic recognition data be stored as the recognition data of the safety sensor 7 that becomes stop reason.
In step 8,15 pairs of following situations of control part detect: whether SC relay 23 actions, and come the rising signals of self- hold circuit 21a or 21b or dropping signal for ending; That is whether vital circuit 14 and 9 actions of running control circuit and escalator 1 stops, and stopping of having determined that fault causes.If can not detect this situation, then be judged as escalator 1 in running.
In step 9, control part 15 enters step 10 (situation of "Yes") detecting under the situation about stopping that fault causes, and does not stop and under the situation about remaining in operation at escalator 1, as the fault detection of mistake and enter step 11 (situation of "No").
In step 10, the intrinsic recognition data of the safety sensor that becomes stop reason 7 that will generate in step 7 is registered as abnormal data.
In step 11, be made as stopping that escalator 1 do not carry out that fault causes, the action of safety sensor 7 is considered as flase drop surveys, remove fault detection status, return step 2 and continue to monitor operative condition.
Then, according to the functional structure chart of Fig. 4, to describing from the transmit status of control part 15 to the abnormal data of monitoring unit 16.

Then, shown in the functional structure chart of Fig. 5, the CPU151 of control part 15 is logic according to the rules, and first signal in the communication data zone of the memory device 152 that is arranged in control part 15 and the zone that writes of secondary signal are write.That is, control part 15 writes the state of FD1 respectively to first signal area in communication data zone, the secondary signal zone is write the state of FD2.For example, if be conducting then write 1, if for by write 0.This action that writes after action in also identical.
Then, when being waited the stop reason eliminated escalator 1 by operator, and when confirming that the SC signal reverts to the situation of conducting state, control part 15 ends secondary signal FD2.The state that escalator 1 can start if this state representation is operated KSW switch 19 i.e. " can reset state ".
Then, escalator 1 is successfully reset if the operator operates KSW switch 19, and then control part 15 is confirmed starting according to the signal of maintenance circuitry 21a, 21b, and the first signal FD1 is ended." resetting state " of this state representation escalator 1.
Monitoring unit 16 regular (per 1 minute and 30 seconds) reads the first signal FD1 in the memory device 152 and the communication data zone of secondary signal FD2, has produced under the situation about changing at the state of these signals, communicates to central monitoring position 18.
In central monitoring position 18, on monitor station 27, show the first signal FD1 and the secondary signal FD2 that receives.Under the situation of carrying out this demonstration, mode with the state of learning escalator 1 easily, if the first signal FD1 and secondary signal FD2 are conducting state, then the display part at monitor station 27 shows " fail to start state ", at the first signal FD1 is conducting state and secondary signal FD2 is under the situation of off condition, show " can reset state ", be under the situation of off condition, show " resetting state " at the first signal FD1 and secondary signal FD2.
Thus, the operator of central monitoring position 18 confirms the state of escalator 1 easily, and can over sight (OS).And in central monitoring position 18, whether the operator can be with the first signal FD1 that accepts from the escalator 1 that has abended and the state of secondary signal FD2, as should making maintenance person to the cooresponding judgement material in scene.
According to present embodiment, control part 15 is by generating the first signal FD1 and secondary signal FD2, and send to remotely central monitoring position 18 via monitoring unit 16 and communication network 17, the current state that abends for escalator 1 becomes clear and definite thus, can prevent N/R maintenance person's correspondence, and can promptly corresponding fault.
In the above-described 2nd embodiment, when the conducting of control part 15 and SC signal synchronously makes secondary signal FD2 end, wait in the unusual operation of eliminating escalator 1 the operator, at the limit switch bounce of safety sensor 7 situation under, even do not eliminate error state, also might become the state of to reset.
Therefore, also can be set certain delay time, when the SC signal becomes conducting reliably, secondary signal FD2 be ended between the ending of the conducting of SC signal and secondary signal FD2.
As the method that is set this delay time, can decide by control part 15 in-to-in application programs, also can on circuit, make its delay.As for example being delay time 1 second～5 seconds.
In addition, the first signal FD1 also can similarly be provided with delay time, after escalator 1 starts reliably, the first signal FD1 is ended.
