Abstract

PROBLEM TO BE SOLVED: To improve maintenance work efficiency while enabling the operation sound of an escalator to be remotely confirmable, by converting a sound detected by a microphone arranged in a frame at a step lower part, into a sound signal, to memorize the sound signal in a memory means, and also transmitting a memorized sound symbol to an observation room via a telephone circuit. SOLUTION: Plural microphones 2 and 3 are arranged in the inside of a frame 1 positioned on the lower part of a step thereon passengers ride, and a sound, detected by the respective microphones 2 and 3 during the operation of an escalator, is converted into a sound signal to memorize the sound signal in an escalator condition memory device 6. Then when the escalator is operated, a stop signal is not inputted from a control device 4, and also an escalator abnormality signals is not inputted by an abnormality detection device 5; a regeneration request signal is inputted into the communication device 5A of the device 5 via a telephone circuit 7 from a monitor device 8B and a communication device 8A installed in an observation room 8. After that, respective memorized sound signals are selectively outputted to be regenerated by a speaker via the device 8B.

First, the escalator is operating, and the sound detected by the microphones 1 and 2 is stored endlessly in a predetermined area as a sound signal in the escalator state storage device 6. 4 determines whether an escalator stop signal has been output (step S
1) When the stop signal is input, the storage is stopped (procedure S)
2). If the escalator is operating and the stop signal is not input in step S1, it is determined whether there is an escalator abnormality signal output by the abnormality detection device 5 (step S1).
3) When an escalator abnormality signal is input, step S2
If the escalator abnormality signal is not input, the monitoring device 8B provided in the monitoring room 8
B-Communication device 8A-Phone line 7-Communication device 5A-Abnormality detection device 5-Escalator status storage device 6A It is determined whether or not there is a reproduction request signal for reproducing and outputting the stored sound signal (step S4). When the reproduction request signal is input, the process proceeds to step S2, where the sound of the microphones 2 and 3 stored in the escalator state storage device 6 is stored. Select and output a signal. Here, the sound signal output from the escalator state storage device 6 is sent to the monitoring room 8 of the escalator state storage device 6-communication device 5A-telephone line 7-communication device 8A-monitor device 8B and is monitored via the monitor device 8B. The sound is reproduced on a speaker (not shown) (step S5). Next, the escalator state storage device 6 determines whether or not there is a re-established signal output from the monitor device 8B (step S6). If there is, the reproduction is stopped (step S7). The presence / absence of the output storage start signal is determined (step S8), and if yes, the sound detected by the microphones 2 and 3 is stored again (step S9).
Here, when the reproduction request signal is not input from the monitor device 8 in step S4, the process proceeds to step S9, and the storage of the microphones 2 and 3 is continued.
