JP 2005-145698 A JP-A-6-227770

The conventional escalator seismic control operation system can receive real-time earthquake information and stop the escalator in advance. However, a maintenance engineer who is a specialized engineer has to be dispatched after that. .
Moreover, even if it is proposed in an elevator, an escalator has not been proposed a technique for automatically performing an inspection performed by a special engineer when an earthquake occurs and comparing abnormal sounds with those in a normal state.

  The present invention has been made to solve the above-described problems. When an earthquake detector is connected to an escalator and the earthquake detector is activated, the escalator is stopped, and if the earthquake detection level is particularly low, it is automatic. An escalator recovery operation device for an escalator that returns, performs diagnostic operation if low, and remains stopped if high is provided.

  In the escalator recovery operation device for an escalator according to the present invention, an earthquake detector is connected, an escalator control panel that stops the escalator when the earthquake detector is activated when an earthquake occurs, and an escalator traveling sound is installed in the escalator. The sound collecting device that collects sound and the normal running sound of the escalator collected by the sound collecting device are stored in advance, and when performing an automatic inspection operation in the event of an earthquake, the inspection operation collected by the sound collecting device The escalator control panel is equipped with an abnormal sound diagnosis device for inspection operation by comparing the normal travel sound with the normal operation sound and determining whether the inspection sound is within the specified value. If the running sound is within the specified value, it is judged as normal and the escalator is automatically returned to normal operation.On the other hand, if the running sound during the inspection operation exceeds the specified value, it is judged as abnormal. While it reported to the remote monitoring center, and is intended to stop the escalator.

  A plurality of seismic detectors comprising an extra low seismic detector having an extra low seismic detector level, a low seismic detector having a low seismic detector level, and a high seismic detector having a high seismic detector level. An escalator control panel that is connected and stops the escalator when the seismic detector is activated in the event of an earthquake, a sound collector that is installed in the escalator and collects the running sound of the escalator, and an escalator collected by the sound collector The driving sound during normal operation is stored in advance, and when performing automatic inspection operation in the event of an earthquake, the traveling sound during inspection operation collected by the sound collector is compared with the driving sound during normal operation. The escalator control panel automatically returns the escalator to normal operation when a special low earthquake detector is activated, and detects high earthquakes. When the alarm is activated, the remote monitoring center is notified and the escalator is stopped. When the low-earthquake detector is activated, the automatic inspection operation is controlled, and the running sound during the inspection operation by the abnormality diagnosis device is within the specified value. If it is normal, the escalator is automatically returned to normal operation.On the other hand, if the running sound during the inspection operation exceeds the specified value, it is determined as abnormal and the remote monitoring center is notified and the escalator is turned on. It is to stop.

  In addition, the abnormal sound diagnosis device stores in advance the escalator normal slow running sound and normal running sound in advance, and when performing an automatic inspection operation in the event of an earthquake, during the inspection operation at the slow speed collected by the sound collector. Compares the running sound during normal inspection and the traveling sound during normal inspection with the normal slow traveling sound and normal traveling sound to determine whether the traveling sound during normal and normal speed inspection operations is within the specified value. The escalator control panel is controlled to perform automatic inspection operation at low speed and normal speed when the low earthquake detector operates, and the running sound during inspection operation at the low speed and normal speed by the abnormality diagnosis device is the specified value. If it is within the range, it is judged as normal and the escalator is automatically returned to normal operation.On the other hand, if the running sound during inspection operation at slow speed and normal speed exceeds the specified value, it is judged as abnormal and the remote monitoring Thereby notify the coater, but to stop the escalator.

  The abnormal sound diagnosis device collects sound by a sound collecting device, stores an average sound pressure level for a certain time for each frequency, and compares it with the sound pressure level at the time of inspection operation.

  Further, the elevator control panel announces not to get on the escalator when performing an automatic inspection operation in the event of an earthquake.

  According to the present invention, it is possible to automatically perform an inspection performed by a professional engineer without an engineer, and to quickly recover the escalator. In addition, if the escalator travels due to an earthquake, the equipment may be damaged, and an abnormality will be detected by diagnostic operation and the escalator will stop immediately without causing the escalator to travel. Can be avoided.

FIG. 1 is a system configuration diagram showing an escalator recovery operation device for an escalator according to Embodiment 1 of the present invention, and FIG. 2 is for recording the sound pressure during normal operation of the recovery operation device for an earthquake according to Embodiment 1 of the present invention. FIG. 3 is a flowchart for explaining the operation of the escalator recovery operation device at earthquake in Embodiment 1 of the present invention.

  In FIG. 1, 1 is an escalator control panel, 21 to 23 are seismic detectors connected to the escalator control panel 1, 21 is an extra low earthquake sensor having an “extra low” seismic sensor level, and 22 is an A low seismic sensor having a “low” seismic sensor level, 23 is a high seismic sensor having a “high” seismic sensor level. 3 is an abnormal sound diagnosis device connected to the escalator control panel 1, 4 is a sound collection device including microphones provided at a plurality of locations of the escalator drive part, and the traveling sound of the collected escalator is abnormal sound It is sent to the diagnostic device 3. 5 is a passenger announcement device provided at the ceiling of the entrance / exit of the escalator, 6 is a remote monitoring device connected to the escalator control panel 1, 7 is a public line, and 8 is a remote monitoring center.

Next, the operation of recording the sound pressure of the running sound when the escalator is normal will be described with reference to the flowchart of FIG.
First, a normal sound pressure measurement mode is set by operating a switch or the like of the escalator control panel 1 during normal operation (step S201). Next, in step S202, the escalator travels at a slow speed for a certain time. In step S203, the traveling sound is collected by the sound collecting device 4, and the abnormal sound diagnosing device 3 records the average sound pressure level for a certain time for each frequency when traveling at a low speed. Next, in step S204, the escalator travels at a normal speed for a certain time. In step S205, the traveling sound is collected by the sound collecting device 4, and the abnormal sound diagnosis device 3 records the average sound pressure level for a certain time for each frequency during normal speed traveling. Thereafter, the normal sound pressure measurement mode is canceled in step S206.
As a result, the average sound pressure level during normal speed travel and the average sound pressure level during normal speed travel are recorded in the abnormal sound diagnosis device 3.

Next, the automatic check operation of the escalator recovery operation device during an earthquake will be described with reference to the flowchart of FIG.
First, when an earthquake occurs (step S301), the earthquake detectors 21 to 23 operate and the escalator stops in step S302. Next, if the level of the seismic detector is “special low” at the time of operation of the extra low earthquake detector 21 in step S303, the process proceeds to step S313, the escalator returns and returns to the normal driving operation. If the seismic detector level is “high” at the time of operation of the high seismic detector 23 in step S304, the process proceeds to step S314, and the remote monitoring center 8 is notified, until a specialist engineer arrives and the inspection is completed. A stop state is set (step S315).
If the earthquake detector level is “low” during the operation of the low earthquake detector 22 in steps S303 and S304, the process proceeds to step S305, and the passenger announcement device 5 performs the automatic inspection operation, so the escalator is not boarded. To start the announcement. Then, in step S306, an automatic inspection operation is performed at a slow speed, and a traveling sound is collected by the sound collecting device 4 in step S307, and the sound pressure level is stored in the abnormal sound diagnosis device 3 at a normal slow speed. Compare the running sound pressure level with each frequency to determine whether the sound pressure level collected during the inspection operation is within the specified value. If the sound pressure level exceeds the specified value in step S307, the process proceeds to step S314, the remote monitoring center 8 is notified, and the state is stopped until a specialist engineer arrives and inspection is completed (step S315). On the other hand, if the sound pressure level is within the specified value in step S307, the process proceeds to step S308, and when the comparison has passed for a certain period of time, the automatic inspection operation by slow speed running is stopped (step S309). Further, the process proceeds to step S310, an automatic check operation is performed by normal speed running, and the running sound is collected by the sound collecting device 4 in step S311, and the sound pressure level is stored in the abnormal sound diagnosing device 3. The normal speed traveling sound pressure level is compared with each frequency to determine whether the sound pressure level collected during the inspection operation is within a specified value. If the sound pressure level exceeds the specified value in step S311, the process proceeds to step S314 to notify the remote monitoring center 8 and stop until a specialist engineer arrives and the inspection is completed (step S315). On the other hand, if the sound pressure level is within the specified value in step S311, the process proceeds to step S312, and when the comparison has passed for a certain period of time, the automatic inspection operation by the normal speed traveling ends and returns to the normal traveling operation as it is (step S313).

As described above, when the occurrence of an earthquake is detected, the escalator is stopped, and if the level of the earthquake detector is “low”, the restoration diagnosis operation is automatically performed. In this diagnostic operation, sound collectors are installed in advance at multiple locations on the escalator, and the normal and low-speed running sounds and the surrounding sounds are recorded, and an earthquake occurs and is relatively light. First, the passengers were announced not to get on the escalator, and then the inspection operation was performed at a slow speed. Compared with the normal driving noise, if the driving noise was loud, it was judged abnormal. Stop. In the normal state, the inspection operation is subsequently performed at the normal speed, compared with the normal traveling sound, and when the traveling sound is loud, it is determined as abnormal and the escalator is stopped. In the normal state, it can be determined that there is no damage to the escalator device (normal) and normal operation can be resumed.
As a result, inspections performed by specialized engineers can be automatically performed without engineers, and escalators can be quickly restored. In addition, when the escalator is run due to an earthquake, if the equipment is damaged, an abnormality is detected through diagnostic operation and the escalator is stopped without running, so avoid damaging the escalator. be able to.
