Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the "state of cause of stoppage" of a failed machine or to those in an outdoor or indoor escalator of a single machine or a plurality of machines, and a trouble of work on a moving walkway (moving walkway). "Failure response priority" of the above, and in the case of failure response work of the manager in the field, notify the "location of the cause of the stop" so that the location of the cause of the stop can be found and its status can be confirmed at an early stage. The present invention relates to a passenger conveyor management system capable of quickly recovering and responding to the cause of stoppage.

Further, as the support of the maintenance staff to the management staff, it is automatically detected and judged from the "state of failure and the status of failure management of the management staff" that the maintenance staff needs to support the failure management. Regarding a passenger conveyor management system that can automatically notify the maintenance company's information center of the information of "status of failure and status of failure support of manager" by telephone line and perform operation restoration by failure support of maintenance staff at an early stage It is a thing.

In particular, due to the problem of the distance and the wiring route, even if the wiring for the management exclusive line connecting the outdoor escalator and the management room for managing the outdoor escalator is impossible, the above-mentioned management staff or maintenance staff deal with the failure. The present invention relates to a passenger conveyor management system capable of early operation recovery. In other words, a plurality of outdoor escalators that are installed within a range of about 10 minutes by a car or the like and cannot be wired with a dedicated line are managed using existing public lines.

2. Description of the Related Art Recent social trends and social needs for elevator equipment are as follows. For example, in order to secure functionality and safety, the station building has been changed to a bridge station to be connected to a pedestrian deck (a large pedestrian bridge in front of the station connected to the station building) in order to ensure the functionality and safety of the station building. The connection between station buildings is also being promoted. As a result, the elevated / underground station buildings and the distance / height difference between passages are increasing, and the height difference of the walking flow lines related to the station buildings is widening. On the other hand, the installation of pedestrian bridges on general roads has increased the height difference of the pedestrian crossing crossing the roadway for traffic safety.

[0007] These walking lines with increased height differences cannot be dealt with only by stairs, and as a measure for height difference, an escalator is installed near a station with a large amount of traffic, and as a measure for height difference and welfare measures for people with disabilities. The installation of elevators and wheelchair escalators is essential.

[0006] Even in the redevelopment project of the station plaza where various traffic functions and users are scattered, since the pedestrian separation to secure the traffic safety of users is the basic, it is included the conversion to the bridge station and the pedestrian deck installation. The pedestrian deck is equipped with outdoor lift equipment as a means of moving the three-dimensional walking flow line for the purpose of welfare and convenience for users of the station and the commercial area in the suburbs.

[0007] These outdoor elevator facilities are often installed on outdoor works such as pedestrian decks, and in order to exert the function of the facility, the elevator facilities supporting the three-dimensional walking flow lines can be operated safely and smoothly. It is necessary to
Escalator operation management is an important position for the maintenance of facility operation.

A conventional escalator management system will be described with reference to FIG. FIG. 23 is a diagram showing a schematic configuration of a conventional escalator management system. It should be noted that there is a part indicated as "S" in each of the following figures, which means an escalator.

In FIG. 23, 1 is an outdoor escalator installed on the pedestrian deck, for example, and 2 is a drain tank provided below the outdoor escalator 1.
Also, 3 is an escalator control panel installed in the machine room,
Reference numeral 4 is an internal safety switch failure management device. Further, 5 and 6 are intercoms installed above and below the outdoor escalator 1, and 7 and 8 are ITVs installed above and below the outdoor escalator 1. Although not shown, the outdoor escalator 1 is provided with a failure indicator for managers.

Further, in the figure, 9 is a management room where a manager is stationed and is installed near the outdoor escalator 1
Reference numeral 0 is an escalator monitoring board connected to the escalator control board 3 of the above-mentioned applicable machine and another machine not shown through a dedicated line, 11 is an intercom, and 12 is an ITV monitor.

Here, the main work of operation and management of the outdoor escalator 1 will be described. The operation management includes operation management, cleaning management, maintenance management, and document management.
The operation management includes operation management, wheelchair operation management, operation monitoring, and status failure management.

[0012] As the main operations, the above-mentioned operation management includes daily operation stop operation, daily inspection operation, daily cleaning operation, and emergency operation operation using the intercom. Further, the wheelchair operation management includes wheelchair operation work using an intercom and wheelchair operation support. The operation management includes video monitoring using the ITV monitor 12 and operation status monitoring using the escalator monitoring panel 10. Further, the status failure management includes failure monitoring using the escalator monitoring panel 10, status failure recording, and failure handling. Detailed description of the cleaning management, maintenance management, and document management will be omitted.

The following problems have occurred in the above operation management. First, the problems that have been latent and have become apparent by installing an escalator outdoors are as follows. Abnormal escalator outages are frequently occurring due to mischief, and because the above pedestrian decks are public places, measures and measures to shorten the recovery time are important issues. According to the on-site failure data, about 95% of the abnormal stop is thought to be due to mischief, and it has been revealed that after the abnormal stop of the escalator, the safety switch is restored and the escalator can be restarted.

In dealing with the administrator who has abnormally stopped the escalator, there is a problem that the administrator is performing the restart operation uneasily because the location of the cause of the stop is unknown. Therefore, in a mischievous manifestation place, there may be frequent requests for maintenance dispatch to the maintenance company.

Next, the problems of the monitoring technique that have not been solved even now are as follows. The problem with monitoring technology is
Although there is a demand for an escalator remote monitoring system that enables monitoring in consideration of disasters and backup of operation management of managers, conventional escalator management systems can only remotely monitor failures caused by escalator equipment failure, Disaster-friendly monitoring by the information center of the maintenance company is technically difficult and has not been resolved.

In the conventional management system, when an abnormal stop failure occurs, an abnormal stop is displayed on the escalator monitor panel 10 of the control room 9, and if the cause of the abnormal stop is the operation of the internal safety switch, the maintenance company I immediately reported to the information center.

Further, in the conventional management of the failure of the manager, the manager visits the outdoor escalator 1 which has stopped and confirms the failure state, and then returns to the management room 9 as necessary to call the maintenance staff of the maintenance company. Was being carried out. However, management room 9
It took a long time to check the condition of the outdoor escalator 1 and call maintenance personnel at a long distance between the outdoor escalator 1 and the outdoor escalator 1, so the recovery was significantly delayed. And this correspondence situation was frequently caused by mischief.

[0018]

In the conventional escalator management system as described above, the escalator monitoring panel 10 on the management room 9 side displays the collective abnormal stop and the individual safety switches. However, in these displays, firstly, "state of cause of stoppage" is unknown, so "urgency is unknown". Second, depending on the content of the failure that occurred, it is unclear or unclear whether the personnel who can deal with the failure are the management staff, the maintenance staff, or both. From the above-mentioned first and second states, when a plurality of failures occur at the same time, the "fault response priority to the faulty machine" becomes unclear, and there is a problem that the manager has a hard time responding.

In addition, in the failure indicator for the manager installed in each outdoor escalator 1, thirdly, when the manager arrives at the malfunctioning machine, the location of the cause of the stop is unknown. Fourth
In addition, each safety switch is displayed with a code number and safety switches that cannot be dealt with by an administrator are also displayed, which makes it difficult for an administrator who handles a failure to use the switch. From the above-mentioned third and fourth states, when the operator arrives at the faulty machine due to the faulty response, the work of searching for the location of the cause of the stop is first carried out. In this work, check all switches of the external safety switch and check the status in the vicinity, identify or estimate the location of the cause of the stop, determine whether an accident will occur even if the escalator is restarted, Perform escalator restart operation. However, since the cause is often unknown, there was a problem that the escalator restart operation, which was anxious, was being performed. Furthermore, there is a problem that the work content is prolonged due to this work content, and the operation recovery is delayed.

If the manager is not in the management room 9, failure information cannot be transmitted to the manager. From this state,
If the administrator cannot see the escalator monitoring panel 10 in the management room 9, he or she cannot notice the abnormal stop and failure of the escalator. Since the administrator often stays outdoors or in another machine room for daily inspection and cleaning of the escalator, he / she cannot notice the abnormal stop and failure of the escalator, which causes a problem that the recovery of the failure is delayed.

Further, in the remote monitoring at the information center of the maintenance company, since the monitoring in consideration of the disaster at the information center cannot be carried out, the state of the cause of the stop is unknown. From this state, the dispatch for maintenance personnel's failure,
There was a problem that the work was significantly delayed after the phone call from the corresponding manager to the support request for the maintenance staff. In addition, a person, that is, an information center staff member, makes a follow-up to the recovery of the failure of the manager, and the manager does not detect a state in which the manager cannot cope with the abnormal stop failure of the escalator as an abnormal state. From this state, there is a problem that it is not possible to prevent the human from making a mistake in the judgment, delaying the dispatch of maintenance personnel for failure response and delaying the failure recovery of the escalator.
Further, an information center member determines and follows a safety switch operation failure due to mischief or the like when the escalator is in a rest state, for example, in a stopped state such as at night. From this state, it was impossible to prevent the human from making a mistake in the judgment, and there was a problem in that the maintenance personnel could not be dispatched to deal with the failure in order to secure the escalator activation in the morning, and the failure recovery of the escalator would be delayed.

Further, it is desirable that the management room is originally located near the installation site of the outdoor escalator, which allows easy wiring of a dedicated management line connecting the outdoor escalator and the management room, in terms of operation management. However, the management room requires facilities such as toilets, water, electricity, gas, and air conditioning, and it is difficult to secure the installation space for those facilities, or where dedicated lines cannot be installed due to the construction structure. In such cases, a management room cannot be secured near the location where the outdoor escalator is installed. Therefore, it is necessary to secure a management room in a place away from the place where the outdoor escalator is installed.The problem is that if the distance is too far, it will be difficult to install a dedicated line and the management room cannot be installed in an appropriate place. It was

Therefore, the present invention has been made to solve the above-mentioned problems, and in the work of dealing with a failure of an escalator or a moving walkway, an administrator is asked to "state of cause of stop" of the failed machine or " `` Fault response priority '' is notified, and in the on-site manager's fault response work, the "location cause of the stop cause" is notified so that the location of the cause of the stop cause can be found and its status can be confirmed at an early stage. It is an object of the present invention to obtain a passenger conveyor management system that can promptly deal with the cause of stoppage.

Further, according to the present invention, as the support of the maintenance staff to the management staff, "the status of failure and the status of failure management of management staff" are provided.
Automatically detects and determines that the maintenance staff needs assistance in troubleshooting, and automatically reports the information of "failure status and manager's failure response status" to the information center of the maintenance company by telephone line. The purpose is to obtain a passenger conveyor management system that can be notified and notified and operation restoration can be carried out at an early stage due to a maintenance staff failure response.

Further, according to the present invention, the operation and management can be performed even in the near field where the wiring of the dedicated line cannot be performed due to the construction structure, the wiring of the dedicated line is difficult, and the operation management can be performed even in the place away from the installation location of the outdoor escalator. The purpose is to obtain a passenger conveyor management system in which a management room can be installed within a predetermined distance from the escalator.

Also,
FIG. 4 is a side view showing installation locations of main safety switches.

For example, as shown in FIG. 3, the "emergency stop button" is abbreviated as "E-STOP", and its function is a button for the user to perform an emergency stop operation at some time. As shown in FIG. 4, four outdoor escalator 1 are installed on the upper, lower, left, and right sides. Similarly, the "hand guard switch" has an abbreviation "HG" as shown in FIG.

Here, the information classification of the failure of the escalator management system will be described with reference to FIG.
FIG. 5 is a diagram showing a relationship between each safety switch of the escalator according to the first embodiment of the present invention and a section of failure information.

In the conventional alarm monitoring, remote monitoring of the escalator was impossible because of fear of frequent alarms and difficulty in ensuring safety when alarms were restricted. Therefore, when starting the escalator remote monitoring, a concept of escalator failure information processing which is not generally present at present is needed, and therefore the solution of the failure information classification as shown in FIG.

As shown in FIG. 5, the plurality of safety switches installed on the outdoor escalator 1 are first set as follows.
Divided. In other words, when the escalator abnormally stops and malfunctions, the administrator responds to the malfunction and classifies as follows based on the installation location.

First, there is a safety switch, such as E.STOP, installed in a place where the manager can confirm. This switch category is called "external first switch".

Secondly, there are safety switches, such as HGS, SSS, and CRS, which are installed in a place where the manager can confirm and operate when something is sandwiched between the facilities. The division of these switches is called "external second switch".

Thirdly, there are safety switches, such as DCS, SRS, SLS, etc., which are installed in a place where the administrator cannot confirm or deal with them and the maintenance personnel should confirm or recover. The division of these switches is called "internal switch".

Next, as shown in FIG. 5, the information obtained by each of the above-mentioned three safety switches is divided into the following five categories based on the content of the failure.

The "external E-stop failure" is an emergency stop operation of the external first switch, which is operated by the user when preventing mischief or an emergency, when an emergency occurs, or when preventing an accident from expanding to an area where the safety switch is not installed. However, since it is information that it is necessary to deal with the administrator other than the safety switch installation location, there is a concern that "the state in which the emergency response of the administrator is necessary" may occur due to the operation of the external first switch. It was positioned as a failure. (Classified as information not related to switch operation time.)

The "external minor failure" is the information obtained by detecting the instantaneous operation of the external second switch for less than a few seconds.
There was almost no occurrence of "a situation in which an emergency response of the manager is necessary" due to the operation of the external second switch, and it was positioned as a malfunction due to mischief of the external second switch.

Since the "outside failure" is the information of detecting the operation of the external second switch for several seconds to less than tens of seconds, the "secondary switch operation" indicates that "the emergency response of the manager is required". Positioned as a failure that is likely to occur.

Since the "external serious failure" is the information that the operation of the external second switch for several tens of seconds or more is detected, "the state in which an emergency response by the manager and the maintenance staff is required" due to the operation of the external second switch. It was positioned as a failure that occurred.

Since the "internal failure" is the information obtained by detecting the instantaneous operation of the internal switch for less than a few seconds, the failure "caused by the manager and the emergency response of the maintenance person" occurs due to the operation of the internal switch. I positioned it.

Finally, as shown in FIG. 5, the information obtained by each of the safety switches divided into the above three categories is divided into seven categories as the following failure information categories in consideration of the condition of restarting the escalator.

The external first switch is classified into "fault information 1" and "fault information 2" according to whether or not the escalator is restarted within a certain period of time.

The external second switch has "fault information 3" in which each switch has an operating time of less than a few seconds as one category.
The operating time is from several seconds to less than several tens of seconds, and it is divided into 2 according to the presence / absence of restarting the escalator within a certain time into "Failure information 4" and "Failure information 5", and the operating time is more than tens of seconds. Is defined as 1 category and is defined as "fault information 6".

The above-mentioned internal switches are classified as "fault information 7" as one category.

Then, the classification of the failure information based on the positioning of the failure and its detection and notification are as follows.
The failure information to be reported to the information center of the maintenance company is the following failure information 2.5 / 6/7.

"Fault information 1" is as follows. "There is restart within a certain time" of external E-stop failure,
Since the escalator has to be restarted by the administrator within the "time required to respond to the administrator" and the "status check time" (about several tens of minutes in the field setting) since the abnormal stop occurred, "failure status check and restart operation" Is completed, the failure display recording device 43 and the telephone A44 of the management room 9, the pager 28 of the manager and the telephone C48 of the second management room 29 are notified, and the information is sent to the information center of the maintenance company. It was decided not to report. As the content of the notification to the manager, data is reported to the failure display recording device 43 of the management room 9, and then the manager A troubles in the management room 9 (emergency stop button / external switch failure).
Information is reported by a voice message "Occurrence of external switch failure of Unit No. 00", then this information is reported by a pager 28 by a numeral, and the telephone C in the second control room 29 is reported again by voice.

"Failure information 2" is as follows. "No restart within a certain period" of external E-stop failure
From the occurrence of the abnormal stop, the failure display recording device 43 and the telephone A44 of the management room 9, the pager 28 of the manager and the second management room 2
Despite the fact that the failure information of "Notification of the failure information 1 to the administrator" is reported to the telephone C48 of No. 9, within the time of "the time required to deal with the administrator" and "the situation confirmation time". Since there is no restart of the escalator by the administrator, the "failure status check and restart operation" is incomplete, so it is assumed that the administrator has not responded, so it was notified to the information center of the maintenance company. As the content of the notification to the information center of the maintenance company, information about a failure not compatible with the emergency stop button is reported.

"Failure information 3" is as follows. For an external minor failure, the safety switch operation time is less than a few seconds, and only the failure display recording device 43 and the telephone A44 of the management room 9, the pager 28 of the manager and the telephone C48 of the second management room 29 are notified, and the maintenance company The information center will not be notified. Data is reported to the failure display recording device 43 of the management room 9 as the content of the notification to the manager, and then the management room 9
Information of failure (emergency stop button / external switch failure) corresponding to the administrator on the telephone A
Then, the pager 28 is notified of this information by numeral, and the telephone C of the second control room 29 is again notified by voice.

"Failure information 4" is as follows. In the case of "restart within a certain period of time" for external medium failure, the safety switch activation time is set to a few seconds to less than several tens of seconds, and "time required for handling an administrator" from the occurrence of an abnormal stop Since the escalator is restarted by the administrator within the time of (about), it is assumed that the "fault status confirmation and restart operation" has been completed, and the fault display recording device 43 and the telephone A44 of the management room 9 and the pocket of the administrator. Only the telephone C48 of the bell 28 and the second management room 29 is notified, and the information center of the maintenance company is not notified. As the content of the notification to the manager, data is reported to the failure display recording device 43 of the management room 9, and then information about the failure for manager support (emergency stop button / external switch failure) is displayed on the telephone A of the management room 9 as “○”. 〇 No. external switch failure occurred ”was reported by voice, then pager 28

The operation of the first embodiment will be described below. FIG. 6 is a diagram showing the entire information and failure correspondence of the first embodiment. FIG. 6 shows the flow of information between the devices after the escalator has failed, and the flow from the device to the manager and maintenance personnel obtaining each information and dealing with the failure. Hereinafter, the information processing and the display shown in FIG. 6 will be described in this order.

First, the operation of the escalator control panel 3 will be described with reference to FIG. FIG. 7 is a diagram showing a safety circuit of the escalator control panel according to the first embodiment.

In the safety circuit of the escalator of FIG. 7, for example, when E.STOP (upper left) is operated by operation, the safety circuit becomes non-conductive, the electromagnetic contactor coil for the motor main circuit is demagnetized, and the escalator stops abnormally. Occurs. Further, for example, when the HGS (upper left) operates, the same as above is performed. Further, when the DCS operates, it becomes the same as the above.

The escalator control panel 3 outputs a voltage generated as "information A" to the escalator I / F panel 20 from both ends of contact points of each safety switch of the safety circuit in the escalator control panel 3 as operation information of each safety switch. Is output.

E of the safety circuit in the escalator control panel 3
-By making the switch contact of STOP (upper left) non-conductive, a voltage is generated between the terminals t1 and t2 at both ends thereof. The voltage is output as the operation information of E-STOP (upper left). Similarly, the HGS (upper left) becomes non-conductive, so that a voltage is generated between the terminals t5 and t6 at both ends thereof. Similarly, when the DCS becomes non-conductive, a voltage is also generated between the terminals t9 and t10 at both ends of the DCS.

A voltage is generated at the last terminal tN of each safety switch contact of the safety circuit if all the safety switches of the safety circuit are in operation and are in conduction. The voltage is output as safety switch non-operation information.

Next, the operation of the escalator I / F board 20 will be described with reference to FIGS. 8 to 12.
8 to 11 are diagrams showing a circuit of the escalator I / F board according to the first embodiment. In addition, FIG.
It is a figure which shows the relay name of the escalator I / F board of this Embodiment 1, and its function content.

The signal generation circuit 20A of the escalator I / F board 20 of FIG. 8 is a circuit that detects the operation of each safety switch from the escalator control board 3 and creates safety switch operation information and the like.

As shown in FIG. 8, for example, E.STOP
When the operation information (upper left) is input as voltage generation from the escalator control panel 3, the coil T1 of the relay T1 is excited, its make contact T1 is conducted, and the coil TH1 of the relay TH1 is excited. And that make contact point T
H1 becomes conductive and the coil TH1 self-holds. Further, when the coil T1 is demagnetized because the break contact TH1 becomes non-conductive, the coil T1 is disconnected from the safety circuit in the escalator control panel 3 for safety. Then EST
Although the operation information of OP (upper left) is lost, the coil TH1 holds itself.

Similarly, when the voltage from the HGS (upper left) is input, the coil T5 (not shown) of the relay T5 is excited and the coil TH5 (not shown) holds itself. Similarly, the DCS causes the coil T16 (not shown) of the relay T16 to hold itself.

By operating E-STOP (upper left), the safety circuit becomes non-conductive, the electromagnetic contactor coil for the motor main circuit is demagnetized, and at the same time, the brake coil is demagnetized and the brake is closed. When the brake is closed, the brake switch becomes non-conductive and the coil BR of the relay BR is demagnetized. The break contact BR becomes conductive and the coil FOB of the relay FOB is excited. Then, the make contact FOB becomes conductive and the coil FOB holds itself. The same applies to HGS (upper left) and DCS.

Coil TH1, coil SH, and coil F
The method of canceling the self-holding circuit of the OB is to operate the "stop key switch" to the OFF side,
The coil OFF of F is excited to make the break contact OFF non-conductive.

Alternatively, by operating the "driving key switch" up or down to restart the escalator,
The break contact RUNS of the relay RUNS is made non-conductive for 1 second. The break contact RUNS is non-conductive for 1 second immediately after the escalator starts running.

The break contact BRT of the relay BRT
In order to cancel the memory during the momentary operation of the safety switch, becomes non-conductive 2 seconds after the momentary operation of the safety switch. The make contact RUNL of the relay RUNL is conductive for one second while the escalator is running and immediately after the escalator is stopped.

Holds itself.

The make contact FOB is electrically connected when abnormal stop of the escalator occurs as information of abnormal stop. When the stop key switch is turned off or the escalator is restarted, it becomes non-conductive.

The make contact OUSX1 is turned on as long as E • STOP is continuously pressed (at a minimum of 2 seconds) as the operation information of the external first switch. When E / STOP is no longer pressed, it becomes non-conductive.

The make contact OUSX2 is used as the operation information of the external second switch by each external switch (HGS, SS).
It conducts as long as (S, CRS) is operating (minimum 2 seconds). When the external switches are restored, they become non-conductive.

The make contact INSX uses the internal switches (DCS, SRS, SL) as operation information of the internal switches.
While S (S etc.) is operating (minimum 2 seconds), it conducts. When the internal switches are restored, they become non-conductive.

The mark ● in FIG. 14 indicates an LED.

The LED lighting circuit 21a has an "abnormal stop" on the right side when the make contact FOB on the left side of the figure is conductive.
The LED of is turned on.

The break contact S is non-conductive when the safety circuit is normally conductive (when the operated safety switch is restored).
When the safety circuit is not conducting (safety switch is operating), it is conducting. When the break contact S is conductive (when the safety switch is operating), the LED lighting blinking circuit 21b indicates that when the make contact (TH1, TH2, etc.) on the left side of the figure is conductive, the corresponding LED on the right side (E / STOP (upper left) ), E-STOP (upper right), etc. are lit, and the LED is blinked when the break contact S is non-conducting (when the operated safety switch is restored).

When E / STOP (upper left) is activated, the "abnormal stop" LED lights up and the make contact OX1
And the "external" LED lights up. In addition, the make contact TH1 becomes conductive and LE of "E-STOP" (upper left)

Although the classification according to the installation location of the safety switch is “external first switch” / “external second switch” / “internal switch”, the one corresponding to the external first switch is E / STOP. Since there are only types,
Alternatively, in some cases, the external first switch is referred to as an "emergency stop button", and the external second switch is accordingly referred to as an "external switch".

Next, the escalator failure detection board 23
Based on the "information E" from the escalator I / F board 20, the failure information is generated and "information F" for the pager calling / voice notification board 24 and "information O" for the transmitter 25 are output.

Is conducted, the coil B of the relay B is excited. When the make contact OUSX2 is turned on, the coil E of the relay E is excited. Further, when the make contact INSX becomes conductive, the coil I of the relay I is excited.

Then, the make contact A conducts and the make contact B conducts to excite the coil BH of the relay BH, and the make contact BH conducts to hold the coil BH by itself. The relay BH is a relay that stores the operation of the emergency stop button when an abnormal stop failure occurs.

Further, the make contact A is made conductive, and the make contact E is made conductive, so that the coil H of the relay H is excited after 3 seconds, and the make contact H is made conductive so that the coil H holds itself. The relay H is a relay that stores an operation of an external switch for 3 seconds or more when an abnormal stop failure occurs.
