Description

Description: TECHNICAL FIELD The present invention relates to a passenger conveyor control device, and in particular, when an abnormality occurs in a passenger conveyor such as an escalator or an electric road, the abnormality is transmitted through a telephone line or the like. It is possible to determine whether or not to send an alert (outgoing call) to the central monitoring center,
Further, the present invention relates to a passenger conveyor control device capable of accurately determining whether or not a maintenance staff is to be dispatched to the site to repair an abnormality when a warning is issued.

[Prior art] When an abnormality occurs in the passenger conveyor, the abnormality information is sent to the centralized monitoring center via a telephone line (or a call is made), and the situation is notified each time the passenger conveyor is started or stopped. The centralized monitoring center that received the information examines the contents, and if an abnormality is reported, a system for dispatching maintenance personnel to remove and repair the abnormality of the passenger conveyor that has been reported has recently been requested.

As a similar system of this kind, for example, a system conventionally used in an elevator is known. The reason why this kind of system is used in elevators is that when the elevator is abnormal, the passenger's car is confined, that is, canning occurs, and it is necessary to go to rescue the passenger upon receiving the alarm. is there.

As an example of such a system, for example, Japanese Patent Application Laid-Open No. 48-18
The technology described in Japanese Patent No. 942, "Automatic Report Device for Elevator Failure" is known. The system for this elevator automatically issues a warning when a passenger is in a can at the time of failure.

However, in the passenger conveyor, even if a failure occurs, the passengers cannot be canned, so that there has been no such demand in the past.

By the way, the fact that the passenger conveyor is a kind of transportation and a service institution remains unchanged, but in recent years,
From the perspective of improving the comfort of society, there is an increasing demand for prompt repairs for passenger conveyor failures, and the failure that occurs automatically can be communicated to the repairing department, which does not require any human resources for that purpose. There has been a demand for an alarm system for abnormal passenger conveyors.

[Problems to be Solved by the Invention] In order to satisfy the above requirements, it was examined whether or not the existing elevator technology can be applied to a passenger conveyor.
Due to the difference in function from the elevator, it was found that the application of elevator technology at the end had the following problems.

(1) It is difficult to distinguish an abnormal state from a normal state.

Elevators are usually operated by automatic operation, and passengers call a car and command a call on the destination floor to operate. Therefore, it can be said that an elevator that does not move even if there is a call is abnormal.

Passenger conveyors are simply passengers on a moving device. Therefore, if the passenger conveyor that does not move is in an abnormal state, it cannot be generally distinguished depending on the situation at that time.

For this reason, this kind of elevator equipment
When an abnormality occurs, it is possible that passengers are stuck and canned. Therefore, regardless of the cause, it is necessary to immediately report the abnormality to the central monitoring center for rescue and repair. However, at the time of maintenance and inspection, since the safety device is operated and inspected, it is difficult to issue an alarm. Therefore, in such a case, the alarm is suppressed.

As a conventional technique of this type, there is, for example, a technique described in JP-A-61-169464, "Emergency notification device".

On the other hand, the passenger conveyor cannot be issued just because it is not moving as described above.

(2) There are two types of safety devices on the passenger conveyor: automatic return type and manual return type.

In general, passenger conveyors provide:
When this is detected, the safety device stops the passenger conveyor. In some cases, the operation can be performed if the cause is removed after the conveyor is stopped, and in other cases, the cause is fixed and cannot be restored without repair. In the former case, the automatic reset type safety device operates, and in the latter case, the manual reset type safety device operates.

Therefore, if the manual reset type safety device is activated during operation of the passenger conveyor, it is possible to issue a warning in most cases.
It may not be necessary to issue an alarm if the automatic reset type safety device is activated.

As a specific example of the automatic return type safety device, there is a skirt guard switch that detects foreign matter in the skirt guard portion, and this switch is a safety device that automatically returns when the foreign matter disappears. In addition, the handrail of the terminal part is provided in the part where the handrail enters into the device, and the terminal inlet safety switch that operates when the hand of a child is drawn in is also a safety device of automatic reset type. These automatic return type safety devices are of a type that recovers when a safety device is activated and foreign objects are involved due to human beings being removed and rescued after stopping.

As a manual return type safety device, cutting various chains,
There are safety devices such as a device for detecting elongation and a device for detecting overspeed. These safety devices detect anomalies that are mechanically unsafe, and must be repaired when the passenger conveyor is stopped due to the operation of this safety device, and therefore the repair is not performed. It is a safety device that will not recover unless it is restored.

However, in the case of an elevator, when a car is stopped between people on the floor between passengers, the passenger does not stop the car, so that condition should be left as it is. The cause is never removed. Therefore, in the elevator, when passengers are stopped and stopped, it is necessary to immediately report all in order to rescue the passengers.

As described above, the existing technology of the elevator cannot be applied to the passenger conveyor as it is, and it is necessary to newly develop an abnormality alarm device exclusively for the passenger conveyor.

In view of the above-mentioned points, an object of the present invention is to provide a passenger conveyor control device capable of reporting an abnormality of the passenger conveyor to a centralized monitoring center without relying on existing elevator technology.

[Means for Solving the Problems] According to the present invention, the above object is achieved by having the following functions.

Alarm is issued in response to the operation of the manual reset type safety device and the operation of the startup operation means, that is, when the passenger conveyor is operating and the manual reset type safety device operates. I do.

The alarm is issued in response to the operation of the manual reset type safety device, and the alarm is issued in response to the operation of the automatic reset type safety device and the activation operation means of the passenger conveyor.

The alarm is issued in response to the operation of the manual reset type safety device, and is issued when the operation of the automatic reset type safety device reaches a predetermined number of times.

The alarm is issued when the automatic reset type safety device operates and the activation means of the passenger conveyor is operated.

When the activation operation means is operated, if at least one of the safety device of the manual reset type and the safety device of the automatic reset type is operating, it sounds and issues an alarm.

When the passenger conveyor is started and stopped, a warning is issued to the monitoring center, and the contents of the warning include normal stop, emergency stop, automatic return type safety device operation, manual return type safety device operation and preventive maintenance. Report passenger conveyor information such as equipment operating status.

[Operation] When a manual-return type safety device is activated, repair is required. However, simply operating it may cause an alarm even at night when the passenger conveyor is not in use. "Is added so that a warning is issued when it is activated during operation, and unnecessary warnings can be eliminated. In this case, even if the manual-return type safety device is activated during the operation stop at midnight, etc., if the passenger conveyor is operated after that, the startup operation is always performed. By doing so, repair work can be performed.

Even if the automatic return type safety device operates and the passenger conveyor stops, it may not be possible to return if the damaged state is severe. Also at this time, similar to the above, at the time of performing the operation for activation, the alarm is issued on condition that the abnormality is not recovered, so that quick repair can be performed.

When the automatic reset type safety device is activated and stopped, the cause may be a defective setting of the safety device. In such a case, even if the safety device is restarted, the safety device operates many times a day. Therefore, by issuing an alarm on the condition that the safety device is operated a plurality of times a day, it is possible to eliminate unnecessary stoppage of the passenger conveyor.

Since the reporting itself is not labor-intensive,
The number of reports is increased, but instead of the information reported by the centralized monitoring center, the details of the abnormality, that is, normal stop, emergency stop, automatic reset type safety device operation, manual reset type safety device operation, and preventive maintenance device By deciding the operation status and the like, it is possible to decide the dispatch of maintenance personnel for repair. As a result, since the centralized monitoring center can know and monitor all the operation information, more detailed monitoring can be performed.

Embodiment An embodiment of the passenger conveyor according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of hardware showing a configuration of an embodiment of the present invention, and FIGS. 2 to 8 are flow charts for explaining the operation thereof. In FIG. 1, 11 and 12 are electromagnetic contactors for raising and lowering, 15 is a microcomputer, 17 is a start switch,
19 is an alarm ringing switch, 21 is an alarm buzzer, 23 is a stop switch, 25 is an emergency stop switch, 27 and 29 are switches for automatic reset type safety devices, 31 and 33 are switches for manual reset type safety devices, 35, 37 is a switch, 39 is a warning completion indicator light, 41 is a warning notice indicator light, 43 is a warning line, and P is a power supply.

In FIG. 1, the electromagnetic contactors 11 and 12 for turning on the power P of the electric motor for driving the driving machine for the passenger conveyor are moved up and down in the direction of the passenger conveyor (in an escalator, which is one of the passenger conveyors, ascended) , Descending) to operate by switching. This electromagnetic contactor
11 and 12 are turned on by a signal output from the microcomputer 15. The microcomputer 15 receives an instruction from the operator whether to use the passenger conveyor in the forward direction or the return direction by the start switch 17 provided in the manual switch panel provided in the terminal deck of the passenger conveyor or the like. ,
A signal for turning on the electromagnetic contactors 11 and 12 is output.

Before operating the start switch 17, the operator informs the person on the opposite terminal deck that the passenger conveyor is to be started, so that the alarm ringing switch 19 of the manual switch panel input to the microcomputer 15 is input. Then, the alarm buzzer 21 connected to the output of the microcomputer 15 is activated. In this way, the operator operates the start switch 17 by sounding the alarm buzzer 21 to give an alarm, and turns on the electromagnetic contactor 11 or 12 to start the operation of the passenger conveyor.

In this state, general passengers can start using the passenger conveyor.

To stop the passenger conveyor, the operator
The stop switch 23 provided in the manual switch panel that is input to is operated. As a result, the microcomputer 15 releases the electromagnetic contactor 11 or 12. By releasing the electromagnetic contactor, the power supply P of the electric motor for driving the drive machine is cut off, so that the passenger conveyor is stopped.

Next, the contact status of the safety device of the passenger conveyor with the microcomputer 15 and the operation when the safety device operates will be described.

Emergency stop button operated by passengers when they find danger
25 is connected to the microcomputer 15, and when pressed in an emergency to open its contact, the microcomputer 15 causes the electromagnetic contactor 11 or 12
Release and stop. In addition, this emergency stop button 25
Since it has a lock, if you check the safety and then restore it, the passenger conveyor can be operated.

The commands to the microcomputer 15 from the automatic reset type safety device such as the skirt guard switch and the terminal inlet safety switch described above are represented by the switches 27 and 29. The safety device is activated and these switches 2
When the contacts of 7 and 29 are opened, the micro 15 moves to the electromagnetic contactor 1
Release 1 or 12 to stop passenger conveyor. After the safety device has been activated and the fault has been removed, the switch 27 or 29 is reset, its contacts are closed and the passenger conveyor is ready for operation.

The input to the microcomputer 15 from the safety device of the manual reset type represented by the safety device that detects chain breaks, elongation, etc.
This is performed by the switches 31 and 33. The operation when the contact of this switch is opened is the same as when the above-mentioned automatic reset type safety device is operated. The difference is that in order to close the opened switch, the mechanical device is usually out of order, and therefore, it is necessary to be inspected by a maintenance person and then be restored by the maintenance person's hand. The passenger conveyor can then be put into operation.

Further, the switches 35 and 37 are set so as to operate immediately before the switches 31 and 33 of the manual reset type safety device are activated, and do not immediately stop the passenger conveyor, but immediately before the chain It informs that it is in a state where it is necessary to check the extension.

In addition, as an output of the microcomputer 15, it lights up when an abnormality is reported to the centralized monitoring center, and when the alarm indicator lamp 39 and the alarm ringing switch 19 that indicate that the alarm has been activated are operated, the information is concentrated. There is a warning notice indicator lamp 41 which is lit and displayed in order to give a notice to notify the monitoring center. These are provided in the manual switch board. The warning notice indicator light 41 lights up when the safety device is not restored, and when the alarm ringing switch 19 is operated to prepare for the next start, the operator is informed that a warning to that effect is issued. It is for.

Furthermore, a warning line 43 for transmitting a warning signal to the centralized monitoring center is connected to the microcomputer 15. The reporting line 43 may be a dedicated line or a telephone line. A central monitoring center (not shown) can accommodate a plurality of such lines to monitor a plurality of passenger conveyors.

Next, the operation of the embodiment of the present invention will be described with reference to the software flowcharts shown in FIGS. The outline of each of these flowcharts is as follows.

FIG. 2 is a flowchart for executing a sequence related to operation control. This control typically starts and stops the passenger conveyor.

FIG. 3 is a flow chart for explaining the control operation regarding the alarm ringing switch 19 for notifying the person near the terminal deck on the opposite side immediately before the start-up that the passenger conveyor is started.

FIG. 4 is a flow chart for explaining a control operation for creating an operation permission flag for performing control for stopping the passenger conveyor when various safety devices are operated, in contrast to the control of FIG.

FIG. 5 is a flow chart showing details of block 309 of FIG.

FIG. 6 is a flow chart for explaining the control operation for determining whether or not to issue a report to the centralized monitoring center.

FIG. 7 shows, as preventive maintenance, when switches 35 and 37 for knowing beforehand the operation of the safety device of manual reset type are operated,
It is a flow chart explaining control operation which makes a flag for report.

FIG. 8 is a flow chart for explaining the operation of driving the alarm line 43 and controlling the sending of abnormality information to the centralized monitoring center.

Note that the other flowcharts except the flowchart shown in FIG. 5 are ones which are regularly started as one task in the microcomputer and the contents thereof are executed. This starting order is as shown in FIG. 4 → FIG. 3 → FIG. 2 → FIG. 6 → 7.
FIG. 8 is the sequence of each flow in FIG. 8, and each flow is repeatedly executed from the power-on of the microcomputer 15 to the power-off. The activation cycle of each flow is set according to its response. For example, the flow of Fig. 4 is performed every 40ms, and the lowest flow of Fig. 8 is 200ms.
It is done every time.

The operation of the entire embodiment of the present invention will be described below with reference to these flowcharts.

A. General start / stop operation The operation permission flag created by the operation of the flow shown in FIG. 4 is set by the processing of block 317 under the condition that all safety devices are not operating.

When the operator operates the alarm ringing switch 19 to activate the passenger conveyor, an output for ringing the alarm buzzer 21 is produced in block 205 of FIG. 3 to ring the alarm buzzer 21. This ringing is performed only while the switch 19 is turned on, as can be seen from this flowchart.

In the flow shown in FIG. 2, first, the block 103 determines the state of the driving permission flag. In a normal state, the operation permission flag is set, so after confirming that the stop switch 23 is closed in block 105 and that the electromagnetic contactors 11 and 12 are in the released state in block 107, the operation is performed. It is detected in block 109 that the worker operates the start switch 17, and accordingly, in block 111, the electromagnetic contactor 11 or 12 is turned on. When the electromagnetic contactor is turned on, the passenger conveyor starts operating.

When the operation of the passenger conveyor is finished, it is detected in block 105 that the stop switch 23 is operated, and block 115 is detected.
Then, the electromagnetic contactor 11 or 12 is released to stop the passenger conveyor.

In the case of the normal operation described above, in FIG. 6, FIG. 7 and FIG.

B. When the emergency stop button 25 is pressed At this time, in block 303 of FIG. 4, the emergency stop button 2
Since it is detected that 5 has been pressed and the circuit has been opened, at block 305, the emergency stop button operation flag is set.
At 315, the activation flag is present, and at block 319 the driving permission flag is reset to cancel the driving permission.

Therefore, in block 103 of FIG. 2, it is determined that there is no operation permission flag, and in block 115, the electromagnetic contactor 11 or 12 is released and the passenger conveyor is stopped.

At this time, the processing according to the flow of FIGS. 6 to 8 does not operate as in the normal operation.

When the stop button 25 is returned to its original state, the operation flag is reset in block 307, so that block 315 → block 317.
By the processing of (1), the operation permission flag is set again, and the passenger conveyor becomes operable.

C. When the automatic reset type safety device operates The state of the switches 27 and 29 of the automatic reset type safety device is 4th.
If it is determined at block 353 of the flow of FIG. 5 showing the details of block 309 of the figure, and if the safety device is operating, the operation flag is set at block 355, and the passenger conveyor is stopped as described above.

And when the cause that actuated the safety device is removed,
Since the safety device is automatically restored, the holding flag is set in block 353 → block 359 → block 361, and the operation flag is reset in block 363 to return to the normal state. Therefore, thereafter, the passenger conveyor is ready to be activated.

It should be noted that the holding flag is reset at block 369 after checking the elapsed time since it was set at block 367 and after 24 hours. This is because when the automatic return type safety switch is activated again within 24 hours, the alarm flag is set by the process of block 413 → block 415 → block 417 in the flow shown in FIG. This is for issuing an alarm to that effect in the process of block 603 → block 605 in the foo. Therefore, if there is an automatic reset type safety device that operates frequently (twice in 24 hours in this embodiment), that effect will be reported, and repair can be performed by this. Becomes In the embodiment of the present invention, the automatic reset type safety devices are collectively checked, but the number of times may be set for each automatic reset type safety device to issue an alarm. Also, in the flowchart shown in the figure, it is announced that the switch of the safety device will close and then open regardless of the activation of the passenger conveyor.
It may be limited so that the alarm is not issued unless the passenger conveyor is activated.

Further, if the alarm ringing switch 19 is operated before the automatic reset type safety device is restored, the alarm flag is set in block 413 to block 417 of the flow shown in FIG. . For this reason, if the automatic recovery type safety device is deformed and cannot be returned to its original state, the alarm ring switch
By operating 19, the centralized monitoring center can be contacted and repaired.

D. When the manual reset type safety device is activated The state of the switches 31 and 32 of the manual reset type safety device is 4th.
When the manually reset type safety device is activated as detected in block 311 of the flow shown in the figure, the operation flag is set in block 313. With this setting, the operation permission flag is reset as in the case described above, and if the passenger conveyor is in operation, the passenger conveyor is stopped. The manual reset type safety device operation flag is retained as it is, and is reset when the power is turned off for repair or the like and is turned on again.

Further, as a warning that the manual reset type safety device has operated, if the operation flag of the manual reset type safety device is set, block 405 in the flow of FIG.
Then, it is determined whether or not the passenger conveyor is in operation. If the passenger conveyor is in operation, a warning flag is set in block 409, and if it is stopped, a warning is issued by operating the alarm ring switch 19 at the next startup. This is done by setting the flag.

For this reason, since the alarm is issued immediately during the operation and during the next start operation during the stop, it is possible to prevent the alarm from being issued in an unnecessary time.

Although only the main part of the software of the microcomputer 15 has been described above, there is software for controlling the alarming indicator lamp 39 and the alarming indicator lamp 41 in addition to this.

The lighting control of the reporting completion indicator lamp 39 is performed by the block 605 of the flow shown in FIG. 8 described above, which is lit when the reporting line 43 is driven and a reporting is performed, and after the power is shut off at the time of repair, It is configured to turn off when turned on, and informs the operator that a warning has been issued.

The warning notice display 41 is the block 407 of the flow shown in FIG.
Or, it is configured to be turned on when 413 is executed and turned off when block 409 or 417 is executed. To encourage the operation.

In the above-described embodiment of the present invention, when the manual reset type safety device is activated in the middle of the night, a warning is issued at the time of the next start, and the maintenance personnel perform the repair. When it is better to speed up, the block 405 of the flow shown in FIG. 6 may be eliminated and the block 403 may shift to the block 409.

Next, another embodiment of the present invention will be described.

In this other embodiment of the present invention, the condition for issuing a warning is not the time when it is necessary to dispatch a maintenance staff from the centralized monitoring center to repair the condition, as in the above-described embodiment, and to activate the passenger conveyor, It is designed to issue an alert every time the vehicle is stopped.

Therefore, in another embodiment of the present invention, an alarm is issued each time the electromagnetic contactors 11 and 12 are charged and released in blocks 111 and 115 of the flow shown in FIG. By setting the flags and performing the alarm control described with reference to FIG. 8, the states of various operation flags controlled by the flow shown in FIG. 4, the holding flag shown in the flow of FIG.
The notification flag including the alarm flag controlled by the flow shown in FIG. 6 and FIG. 7 is simultaneously reported.

As a result, in the above-described embodiment of the present invention, it is possible to know which information has been issued as the content of the notification at the time of the notification, for the operation of the manual type or the automatic type safety device and the preventive maintenance. In contrast to the contents only, in this other embodiment, as described above, all the information of the passenger conveyor is reported, and the centralized monitoring center judges whether to dispatch a maintenance worker and wastes maintenance. It is possible to perform more detailed monitoring by eliminating the staff dispatch, monitoring the cumulative operation time of the passenger conveyor based on the start / stop information of the passenger conveyor, and monitoring the number of times of starting.

According to still another embodiment of the present invention, information on each start and stop of the passenger conveyor is separately stored in the microcomputer, and the content is periodically (for example, once a day) reported. It was done. According to this other embodiment of the present invention, the normal alarm is issued only at the time of stop.

According to still another embodiment of the present invention, in block 319 of the flow shown in FIG. 4 described above, if the operation permission flag is reset, the passenger conveyor will be in an emergency stop. The alarm flag is set at the same time as the processing to issue an alarm, and the centralized monitoring center makes it possible to judge the dispatch of maintenance personnel in the same manner as described above. The number can be further reduced as compared with the embodiment.

Although the present invention has been described above with reference to some embodiments, the number of times of issuance is highest in the first embodiment of the present invention which is the first to report abnormal operation in which only maintenance personnel are dispatched and repaired. You can reduce If only the dispatch of maintenance personnel is used as the criterion, this method can obtain the maximum effect.

However, when it is desired to obtain not only the information for restoration but also other information, the other embodiments described below are examples in which the maximum effect can be obtained. The intermediate is the last-mentioned embodiment.

As described above, the present invention makes it possible to selectively use the above-described embodiments under actual conditions, and it is significant that it is possible to immediately dispatch a maintenance staff from the central monitoring center in the event of an abnormality requiring repair. As a method of obtaining the information, the above-described embodiments of the present invention can be appropriately used as necessary.

[Effect of the Invention] As described above, according to the present invention, when the safety device of the passenger conveyor operates and stops, the stop cannot be removed unless the cause of the stop is repair by the maintenance personnel. If it is, that is, when the safety device of the manual reset type is activated, a warning is issued when the passenger conveyor is in operation, so maintenance personnel can be dispatched immediately and stop at midnight etc. When the manual reset type safety device is activated, a warning is issued when the activation means is operated, so that maintenance personnel can be dispatched immediately at that time.

That is, according to the present invention, this is because the safety device that automatically recovers when the cause of the stop is removed operates, and when the safety device returns after that, the centralized monitoring center for repairing the passenger conveyor. It is not necessary to dispatch maintenance personnel from the factory and other efficient manual maintenance-type safety devices that do not automatically return to activate the passenger conveyor and stop the passenger conveyor. Can dispatch.

Further, according to the present invention, the following effects can be further obtained.

(1) Since the maintenance personnel can be dispatched when the automatic-return-type safety device operates multiple times within a predetermined time, appropriate measures can be taken against the frequent operation of the safety device. .

(2) Since the maintenance staff can be dispatched when the activation means is operated when the automatic restoration type safety device is not restored, it is possible to dispatch the maintenance staff carefully.

(3) When the startup operation means is operated, when at least one of the manual reset type safety device and the automatic reset type safety device is operating, it has been sounded and an alarm has been issued. Since the alarm ringing switch that is present is used, it is possible to operate without feeling uncomfortable.

(4) When starting and stopping, the passengers are notified of information such as normal stop, emergency stop, automatic reset type safety device operation, manual reset type safety device operation, and preventive maintenance device operation status. It is possible to know the usage status of the conveyor, which allows detailed monitoring.
