Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure coping support device for an elevator remote monitoring device, which is used to grasp a failure situation, a cause of failure, etc. when an elevator failure occurs.

[0002]

2. Description of the Related Art An elevator remote monitoring device is a device that constantly monitors the operation of an elevator and, when a failure occurs in the elevator, notifies the center device of this and recognizes the failure by the center device. The center device that recognizes the above takes the necessary failure recovery measures. An outline of such an elevator remote monitoring device will be described with reference to the drawings.

FIG. 9 is a block diagram of a conventional elevator remote monitoring device. In the figure, 1 is an elevator, and 2 is an elevator control unit that controls the operation of the elevator 1 and creates various data regarding the operation of the elevator 1. Three
Is a terminal device provided in each building, collects the various data of the elevator control unit 2, and detects the presence or absence of a failure of the elevator 1 from these data. Reference numeral 4 is a center device that manages a large number of terminal devices 3, and can be connected to the terminal devices 3 by a telephone line 5. Reference numeral 6 indicates a sales office in charge of maintenance of the elevator 1, and 7 indicates a telephone line for connecting the center device 4 and the sales office 6.

When a failure occurs in the elevator 1, the terminal device 3 determines whether or not there is an abnormality on the basis of the data collected from the elevator control section 2, and if an abnormality is detected, the center device is connected via the telephone line 5. Issue an abnormality to 4. Upon receiving this abnormality report, the center device 4 notifies the sales office 6 in charge of maintenance of the elevator 1 in which the abnormality has occurred to the sales office 6 via the telephone line 7 to prompt the dispatch of maintenance personnel. The maintenance person immediately rushes to the elevator 1 in which the failure has occurred, and performs the required processing for the failure recovery.

[0005]

By the way, statistically looking at the cause of the abnormal alarm, nearly 90% of the causes are mischievous operation of various push buttons of the elevator 1 car or hall,
This is caused by long-term door closing prevention during baggage transportation, jumping pranks in the car, etc., and abnormal reports due to failure of the elevator system itself are less than 10%. However, in the conventional remote monitoring device, maintenance personnel must be dispatched whenever an abnormality is reported.If the abnormality is dispatched due to the former cause, the maintenance personnel should be sent to the site. By the time they arrived, the elevator 1 was almost always operating normally. For this reason, 80% of the total dispatch of maintenance staff for failure notification was wasteful, and work efficiency was significantly impaired. Further, due to the nature of the cause, it is not possible to understand this, and there is a problem that it is impossible to investigate the cause of the abnormality and prevent the recurrence of the abnormality report.

On the other hand, in the case of a cause other than the above, that is, when an abnormality is reported due to a failure of equipment or parts, the maintenance personnel rushing to the site reads the failure data stored in the elevator control unit 2 and decodes it while carrying it. The contents of the failure data are deciphered using the table to identify the failure part. However, since the failure data is more than 100 kinds, it takes a lot of time to read and decipher the failure part. Even if it can be specified, if replacement parts and tools are required, it takes more time to arrange and transport them, and there is a problem that the normal return of the elevator is delayed and the immobility time becomes long. In addition, since the reading and decoding of the failure data is performed at the failure site, maintenance personnel cannot calmly implement these, often resulting in misreading or erroneous decoding of the failure data, which delays the identification of the failure part. There was also a problem.

It is often the case that the failure part cannot be identified even by reading and decoding the failure data. In this case, a plurality of failure parts are estimated, and parts are replaced in order of high possibility of failure. It is necessary to take measures until the failure is repaired.However, this method not only takes a long time to recover, but the true failure part is temporarily damaged by turning on / off the control power supply when replacing parts. There is also a problem in that in this case, the true failure part is left as it is, leading to the recurrence of the failure.

[0008] Furthermore, when the maintenance staff finishes the failure recovery process, he / she is supposed to prepare a failure repair work completion report on site and submit it to the customer. It is composed of items such as failure phenomenon, failure cause, and countermeasure content, and it takes a long time to describe the required items in these items, and during that time, maintenance personnel are restrained and work efficiency is reduced.

An object of the present invention is to solve the above-mentioned problems in the prior art, and to provide a failure coping support device for an elevator remote monitoring device which can significantly reduce the burden on maintenance personnel and shorten the failure recovery time. It is in.

The operation status monitor display screen will be described with reference to FIG. FIG. 6 is a diagram showing the operation status monitor display screen 10. This screen has a screen display layout imitating an elevator device so that the operator can grasp the current operation status of the elevator at a glance. In the figure, D10 represents the name of the building to which the elevator where the abnormality has occurred and the number of the elevator car in letters and alphanumerics, and indicates the current car position, operating direction, and call occurrence status in the vertical direction. It is a display unit for displaying a grid image of the hoistway divided into. This display part D10

At the upper and lower ends outside the square, there are displayed a safety switch on the end floor and a forced deceleration switch on the end floor located at the upper and lower ends of the hoistway of the elevator system. D20 is a display unit that displays the current traveling speed and traveling status of the elevator, D30 is a display unit that displays devices and switches arranged inside and outside the elevator car, and a display unit that is displayed on D40 is abnormal. It is a display unit that displays the time, the abnormality content, and the current operation mode. D50 is a display unit for displaying the operating states of the contactors and devices provided in the machine room equipment, D6
Reference numeral 0 denotes a display unit that displays the operating state of the in-car operation switch. The on-off operation states of the devices and switches are displayed by distinguishing the operation by the color change within the O symbol.
That is, it is displayed in blue when it is operating normally in normal operation, and is displayed without coloring when it is not operating. In case of abnormal operation, a red and blinking display is shown in the circle symbol of the relevant part to clearly inform the operator of the abnormality.

In the present embodiment, the display positions of the devices and the switches are arranged on a screen display imitating an elevator device, but the operating states of the devices and the switches can be displayed side by side in a list. is there. Further, in the present embodiment, the current operating state of the elevator and the operating state of the devices are displayed, but not only the current state but also the states before and after the occurrence of the abnormality are stored in the storage unit 3e of the terminal device 3. It can be displayed by using the data.

In this way, after the screen shown in FIG. 6 is displayed by the process of step S4 shown in FIG. 4, the control unit 9e of the failure handling support device 9 is in a state where the abnormality content issued by the terminal device 3 is confined. Whether or not there is an abnormality is determined from the data indicating the content of the abnormality collected from the terminal device 3 (step S5 shown in FIG. 4). If the state is abnormal in the locked state, the control unit 9e provides the call control unit 9b with The telephone 9j in operation is connected to the intercom in the car, and an instruction is issued to enable communication (step S6 shown in FIG. 4). The operator inquires into the car by using the telephone 9j that can communicate with the intercom in the car, and confirms whether there is a person trapped in the car. If there is a prisoner, talk with the prisoner, tell the rescuer within minutes, end the call, and immediately instruct the maintenance personnel to dispatch. At this time, the failure status of the failed elevator No., whether or not the elevator is stopped, and on which floor if it is stopped, etc. is grasped on the operation status monitor display screen. However, the maintenance staff will be notified in advance to assist the maintenance staff in carrying out rescue activities on-site smoothly.

On the other hand, the control section 9e shifts the processing to the operation status monitor display processing section 9f, and the operation switch in the car of the display section D10 in the operation status monitor display screen should not be turned on in the normal operation. It is judged whether or not the switch is turned on (step S7 shown in FIG. 4), and if there is an abnormality that the switch should not be turned on, the operation status monitor display screen is displayed. Among the operation switches in the car, the corresponding switch is blinked in red (step S8 shown in FIG. 4), and the telephone 9j provided and the intercom in the car are connected to enable communication (step shown in FIG. 4). S9). Further, an instruction message for instructing the operator to return the operation switch to the person trapped in the car and the maintenance staff at the site is displayed on the display screen (step S10 shown in FIG. 4), and the process is ended.

In the process of step S7, when the operation status monitor display processing unit 9f of the failure handling support device 9 determines that the closed state of the operation switches in the car is proper, the operation status monitor display processing unit 9f displays the display unit. The operation status of the safety switch in D60 is judged (step S1 shown in FIG. 4).
1), the relevant safety switch portion of the operation status monitor display screen 10 is displayed in red and blinks, and when the maintenance staff has not issued a dispatch instruction, a message is displayed to instruct the operator to dispatch (FIG. 4). Step S1 shown in
2). Next, the operation status monitor display processing unit 9f notifies the failure information translation cause inference processing unit 9i via the control unit 9e that the cause of the abnormality notification is due to the operation of the safety switch. The failure information translation cause inference processing unit 9i is the terminal device 3
The failure phenomenon of the elevator 1 and the abnormal closing state of the operation switches in the car or the abnormal operation status of the safety switch, which are collected from the above, are stored in the storage unit 9n as the cause of the abnormality and communicated to the terminal device 3 (see FIG. Step S1 shown
3), the failure handling support device 9 ends the operation (step S14 shown in FIG. 5).

In the processing of step S11, when the operation status monitor display processing section 9f determines that the safety device is not operating, the control section 9e shifts the processing to the failure information translation cause inference processing section 9i. The failure information translation cause inference processing unit 9i requests the terminal device 3 to transmit the failure data collected from the elevator control unit 2 via the control unit 9e and the communication control unit 9a. Based on the failure data sent according to this request, the failure information translation cause inference processing unit 9i determines that the terminal device 3
The failure analysis of the elevator 1 at the time of abnormality detection is performed. That is, when a failure occurs in the elevator 1, as described above, the elevator control unit 2 stores 100 or more kinds of failure data such as a failure position, a speed at the time of failure, and an operation state of a device in the control device. The terminal device 3 detects the failure phenomenon of the elevator 1 and reports the occurrence of abnormality to the center device 4,
Therefore, this failure data plays an important role in investigating the cause of failure.

The fault information translation cause inference processing unit 9i translates the fault data that has been sent according to the translation and textification rules stored in the storage unit 9n and displays the textualization (procedure shown in FIG. 5). S15). For example, the failure data “failure number 01 failure speed 30 failure stop position 04 failure before departure floor 01 car failure before failure 040508 device status 0101” is input to the failure information translation cause inference processing unit 9i and the text of the failure phenomenon is input. When the conversion is performed, the sentence of the translation result "No. 1 elevator started at the car call on the 4th floor, 5th floor and 8th floor and stopped at the 4th floor at a speed of 30m / min." Is displayed on the display device 9l. It In addition, the translation of the operating state of the device is "door close confirmation device off
Safety device confirmation device on Magnet brake suction confirmation device on "is displayed.

When the translated text display of the failure data is completed, the failure information translation cause inference processing section 9i infers the cause of the failure. That is, in the storage unit 9n, the troubleshooting knowledge created for each failure phenomenon by using the technical knowledge and experience knowledge possessed by the elevator technician is stored as "if the failure phenomenon is ... And the data of ... If so, the cause of the failure is ... ", and a rule configured in the form of". In addition, based on the technical knowledge and experience of elevator engineers, the coping method to be taken according to the cause of failure, necessary parts name, knowledge about work tools, "If the cause of failure is ... If so, the coping method, the part name, the work tool are ... ", and the rules configured in the form of". The failure information translation cause inference processing unit 9i processes the failure data according to this rule, derives the cause of the failure, the coping method, the necessary part name, and the work tool, stores the result in the storage unit 9n, and displays it on the display device 9l. (Procedure S16 shown in FIG. 5). Upon completion of the above processing, the failure information translation cause inference processing unit 9i controls the processing by the control unit 9e.
Move to.

The control section 9e then shifts the processing to the timing chart display processing section 9h. The timing chart display processing unit 9h extracts, from the storage unit 3e of the terminal device 3, data that is predetermined according to the abnormality detection content, out of various data of the elevator immediately before and after the abnormality detection, and displays a timing chart regarding these (FIG. Step S1 shown in 5
7).

Here, the screen of the timing chart is shown in FIG.
Shown in. In FIG. 7, 11 shows the screen of the timing chart. This screen 11 is a time chart of the state change within a minute time of the operation state data before and after the abnormality occurrence, the control data, the operation state data, and the abnormality occurrence information data collected by the terminal device 3. Is processed by the time chart display processing unit 9h and displayed on the screen of the display device 9l. In the figure, D70 is a display unit for displaying the date and time when the abnormality occurred, the content of the abnormality, and the trigger condition, and
Reference numeral 80 is a display unit for displaying the control signal name (device name) and the contents of the device, D90 is a display unit for displaying the status change of the display device name on a screen whose horizontal axis is time-divided, and D100 is It is a display unit that displays the speed change of the elevator together with the traveling position and displays the trigger occurrence point on the time chart. This display D100
The number indicating the cycle described in the upper part of indicates the time from the time when the trigger occurs. For example, in this embodiment,
One cycle is 1 sec, and the cycle "-5" indicates 5 sec before the trigger is generated, but the time display of this one cycle can be arbitrarily changed. Further, the display position at the time of trigger generation can be changed to the left or right as desired, and the time chart display of each device at that time is also added or deleted to the left or right correspondingly. As an example, the data collection sampling time from the elevator 1 for the data used in the time chart display processing unit 9h is 40 ms, the data collection time is 20 sec before the trigger occurs, and 20 sec after the trigger occurs.
Although c is used, the data collection sampling time can be arbitrarily shortened and the data collection time can be lengthened. Also, the data collection time before and after the trigger is generated can be changed. The device display content can also be arbitrarily changed according to the type of abnormality.

The time chart display screen enables the operator to accurately grasp the instantaneous change of the various data immediately before and after the occurrence of the abnormality in a minute time, and the accuracy of investigating the cause of the failure is greatly improved. The operator examines the display result of this timing chart and the failure cause displayed by the processing of the failure information translation cause inference processing unit 9i, identifies the cause if they are not logically contradictory, and the failure in the storage unit 9n. Data such as a phenomenon and a cause is transmitted to the storage unit 3e of the terminal device 3 via the communication control unit 3f and the control unit 3e,
Contact maintenance personnel as well. The maintenance staff who received the report will bring the necessary parts and work tools according to the failure phenomenon and the cause of the failure, before the dispatch. This reduces the downtime of the elevator 1 due to parts arrangement.

If there is a logical contradiction between the display result of the timing chart and the result inferred by the fault information translation cause inference processing unit 9i, for example, the time when the fault occurs in the elevator 1 and the terminal. The time when the device 3 detects the occurrence of the failure phenomenon of the elevator 1 largely deviates, and the control data and the operation status data of the elevator before and after the abnormality detection collected by the terminal device 3 from the elevator control device 2 are the failure data of the elevator 1. When they are not synchronized with each other, a logical contradiction occurs between the two data. In this case, the failure handling support device 9 sets the abnormality detection condition (trigger condition) for the terminal device 3 to detect the failure of the elevator 1 according to the content of the failure. I will change it. For example, the condition for the terminal device 3 to detect the inoperable state of the elevator 1 and issue a warning is that the elevator 1 enters the inoperable state and continues for a certain period of time to prevent an erroneous alarm, and then detects an abnormality and issues an alarm. ing. Even if the terminal device 3 collects the operation data and the control data before and after the abnormality detection, a delay naturally occurs, and the collected data does not become the data at the time of failure occurrence. Therefore, in this case, it becomes necessary to shorten the abnormality detection condition, that is, the detection time of the unbootable state in this example. In this case, the detection time to be changed is input to the input device 9k. The input data is sent to the trigger control unit 9c, transmitted to the terminal device 3 through the communication control unit 9a, the trigger condition of the abnormality detection unit 3c of the terminal device 3 is changed (step S18 shown in FIG. 5), and then The process shifts to the process of step S13.

Here, in step S5 described above, if the abnormality detection content of the elevator 1 in the terminal device 3 is not the confinement state abnormality, the control unit 9 of the failure support handling device 9
When judged by e, the control unit 9e further judges whether or not the elevator 1 is in normal operation (step S19 shown in FIG. 5). Next, when the elevator 1 is stopped, the control unit 9e determines whether or not a car call or hall call is generated in the elevator 1 (step S20 shown in FIG. 5). , The command generation unit 9d is instructed to register a car call or a hall call on each of the upper and lower floors where the elevator 1 is stopped. In accordance with this, the call creating unit 9d writes the writing unit 3b of the terminal device 3.
A call is registered in the elevator control device 2 through (step S21 shown in FIG. 5). In addition, this call registration is performed by the input device 9k.
It is also possible to manually register an arbitrary floor at. The control unit 9e determines whether or not the elevator 1 has normally operated in response to the registered call (step S22 shown in FIG. 5), and when it does not normally operate, proceeds to step S7. When it is determined that the elevator 1 is operating normally in the process of step S19, or when the elevator 1 is operating normally in the process of step S22, the control unit 9e
The operation diagram display processing unit 9g displays the operation diagram shown in FIG. 8 (step S23 shown in FIG. 5). This operation diagram will be described with reference to the drawing.

FIG. 8 is a diagram showing a display screen of the operation diagram. In the figure, 12 shows an operation diagram display screen. This operation diagram display screen 12 shows the state of the elevator 1 over a long period of time based on the operation state data before and after the abnormality occurrence, the control data, the operation state data, and the abnormality occurrence information data collected by the terminal device 3. It is a display of changes. D110 is a display unit that displays the locus of the operation and stop of the elevator 1, and the horizontal direction of the display screen is divided according to the time, and the vertical direction is divided according to the floor, and divided in that way. When the elevator 1 is stopped on the display screen, a horizontal solid line is drawn at the stop time and the position corresponding to the stop floor, and when the elevator 1 is running, the operation locus is hatched at the time and the position corresponding to the travel floor. Draw. Further, in synchronism with the diagram display of the operation locus, operation changes of the various data are expressed in the form of symbols, colored symbols and timing charts, and trigger occurrences indicating abnormalities are also displayed.

The operation diagram screen 12 makes it possible to grasp, for a long time, the history of occurrence of an abnormality in the elevator, the progress of the abnormality, and the operation status after the abnormality. On the operation diagram screen 12 shown in FIG. 8, for example, an operation locus for 5 minutes is displayed in units of 1 dot and 1 sec, but this time may be variable. Further, the display position of the trigger occurrence point can be arbitrarily changed to the left and right, and the respective displays at that time are additionally displayed or deleted on the left and right correspondingly.
The data display content can also be changed according to the type of abnormality.

Next, the operation diagram display processing unit 9g determines whether or not the elevator 1 has performed a rescue operation before and after the abnormality is detected before and after the abnormality is detected (step S24 shown in FIG. 5), and when the rescue operation is being performed. Indicates that an important failure such as an intermediate stop failure has occurred in the elevator 1, so the process proceeds to step S15. When the rescue operation is not performed, it means that the door is not closed and there is a minor failure such as a failure. In this case, it is determined whether the elevator 1 has been stopped for a long time on the specific floor ( Step S2 shown in FIG.
5) If it is not stopped, it is determined that the abnormality detection of the terminal device 3 is improper, and the error erroneous detection is displayed (step S shown in FIG. 5).
27). Also, if the elevator 1 is stopped for a long time,
This is indicated by the door holder (Fig. 5
