Description

  The present invention relates to a function variable type remote monitoring system and a remote monitoring method for remotely monitoring an operating state of an elevator.

Conventionally, for example, Patent Document 1 is known as a system that monitors the operating state of an elevator and issues a notification to a monitoring center when an error occurs. This is because a large number of elevators and monitoring centers existing in each region are connected by a communication network, and when an operation error occurs, a notification is issued to the monitoring center through a terminal device installed in the elevator. is there. When receiving such notification, the monitoring center responds by displaying it on the monitoring screen.
Japanese Patent Laying-Open No. 2005-22784

  However, in the conventional remote monitoring system, when an operation error occurs on the elevator side, a notification is issued to the monitoring center regardless of the degree of the error. In this case, since various information is constantly sent from the elevator of each property to the monitoring center, if there are frequent error reports, the communication line will be punctured and respond quickly to a wide-area disaster such as an earthquake. There is a problem that it becomes impossible.

  In addition, since there is a report regardless of the degree of error, the monitoring center must determine and deal with the urgency of the report each time, and there is a problem that it is chased by the response.

  In view of this, the present invention is designed so that when an error occurs in the operation state of an elevator, low-urgency notification is suppressed as much as possible, and the monitoring center line is eased and preferentially responding to high-urgency notification. It is an object of the present invention to provide a function-variable remote monitoring system and a remote monitoring method for an elevator.

  A function variable type remote monitoring system for an elevator according to the present invention includes a control panel provided in an elevator, a monitoring device that takes in various signals relating to the operation state of the elevator from the control panel and transfers them to a monitoring center, and the monitoring device. Are provided independently, and when an error occurs in the operation state of the elevator, a signal for controlling the alarm to the monitoring center is output to the monitoring device based on an environmental coefficient indicating the operation environment of the elevator. And an agent device.

  ADVANTAGE OF THE INVENTION According to this invention, when an error generate | occur | produces in the operation | movement state of an elevator, the notification with low urgency can be suppressed as much as possible, and it can respond preferentially with respect to highly urgent notification with the line relaxation of a monitoring center.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an overall configuration of an elevator function variable remote monitoring system according to an embodiment of the present invention.

  In this system, an elevator 11 to be monitored is connected to a monitoring center 12 via a communication network 13. As the communication network 13, a telephone line, the Internet, or the like is used, but the communication form is not particularly limited.

  The monitoring center 12 remotely monitors the operation state of the elevator 11 via the communication network 13. In the example of FIG. 1, only one elevator 11 is illustrated, but actually, various elevators installed in each building are connected to the monitoring center 12 via the communication network 13. The monitoring center 12 constantly monitors the operation state of these elevators as monitoring targets.

  The elevator 11 is provided with a control panel 21, a monitoring device 22, and an agent device 23. The control panel 21 is a control device for performing operation control of the elevator 11, and is configured by a computer having a CPU, a ROM, a RAM, and the like.

  The hoisting machine 24 is driven by a control signal output from the control panel 21. As the hoisting machine 24 is driven, the car 26 and the counterweight 27 are lifted and lowered in the hoistway through the rope 25 wound around the sheave of the hoisting machine 24.

  The car 26 is provided with an operation panel 28 having various operation buttons, a load sensor 29 for detecting the load on the car 26, a door sensor 30a for detecting the opening / closing operation of the car door 30, and the like. . These signals are sent to the control panel 21 via a transmission cable (not shown).

  A monitoring device 22 and an agent device 23 are connected to the control panel 21 in parallel. The monitoring device 22 monitors the operation state of the elevator 11, takes various signals indicating the operation state from the control panel 21, and transfers them to the monitoring center 12. The agent device 23 is individually provided for each property as a high-function monitoring device, and the monitoring function can be arbitrarily changed by a command from the monitoring center 12.

  In the present embodiment, when an error occurs in the operation state of the elevator 11, the agent device 23 determines the necessity of reporting based on the environmental coefficient indicating the operation environment of the elevator 11, and the monitoring device 22 It has a function of controlling the alerting to the monitoring center 12.

  The communication function is provided only in the monitoring device 22, and the agent device 23 is configured to transmit / receive data to / from the monitoring center 12 via the monitoring device 22.

  FIG. 2 is a block diagram showing a functional configuration of the agent device 23.

  The agent device 23 includes interface units 31 and 32, a control unit 33, and a storage unit 34. The interface unit 31 transmits / receives data to / from the control panel 21. The interface unit 32 transmits and receives data to and from the monitoring device 22.

  The control unit 33 corresponds to a CPU and executes a series of processes related to the monitoring function of the agent device 23. In the present embodiment, the control unit 33 is provided with an error selection unit 33a, a report determination unit 33b, and a report control unit 33c.

  The error sorting unit 33a sorts out errors to be monitored that require notification determination. The alert determination unit 33b determines the necessity of alerting the error selected by the error selector 33a based on the environmental coefficient of the elevator 11.

  The reporting control unit 33c instructs the monitoring device 22 to report to the monitoring center 12 when the reporting determining unit 33b determines that reporting is necessary, and it is determined that reporting is not necessary. If it is, a signal for prohibiting the monitoring device 22 from reporting to the monitoring center 12 is output. Further, the notification control unit 33c instructs the monitoring device 22 to issue a report to the monitoring center 12 when the same error occurs a predetermined number of times within a certain period.

  The storage unit 34 stores various data necessary for the processing operation of the control unit 33. The storage unit 34 is provided with a notification management table 34 a for storing the monitoring target and the environmental coefficient set by the monitoring center 12.

  FIG. 3 shows an example of the notification management table 34a.

  Here, “door abnormality” is set as the monitoring target. “Door abnormality” refers to a state in which the car door 30 does not complete door opening or closing within a specified time when the car door 30 is landed. An environmental coefficient K1 is set for this “door abnormality”.

  The “environment coefficient” is a numerical value of the operating environment of the elevator 11 and is determined by the type of building in which the elevator 11 is installed.

  For example, if the elevator 11 is installed in a building having a relatively good environment such as an office building, a school, or a hospital, the value of the environmental coefficient of the elevator 11 is high. On the other hand, the value of the environmental coefficient of the elevator 11 is low if the building is a relatively bad environment such as a multi-purpose building, factory, or station. As will be described later, in the present invention, when the value of the environmental coefficient is high, the criterion for determining the notification is high. Therefore, in the case of the “door abnormality”, if the door opening or closing is not completed within the specified time, the monitoring center 12 is notified.

  The processing operation of the agent device 23 will be described in detail below.

  FIG. 4 is a flowchart showing the processing operation of the agent device 23 in the same embodiment. The processing shown in this flowchart is executed by reading a program stored in the storage unit 34 or the like by the control unit 33 that is a CPU provided in the agent device 23.

  First, a monitoring target that requires notification determination for each property and its environmental coefficient are sent from the monitoring center 12 to the elevator 11 via the communication network 13. The monitoring target and the environmental coefficient are given to the agent device 23 via the monitoring device 22 having a communication function.

  In the agent device 23, when receiving the monitoring target and the environmental coefficient (step S11), the control unit 33 sets these data in association with the measurement table 34a provided in the storage unit 34 (step S12).

  The monitoring device 22 provided in the elevator 11 takes in various signals indicating the operation state of the elevator 11 from the control panel 21 and transfers them to the monitoring center 12 via the communication network 13. In the meantime, it is assumed that the same signal is also sent to the agent device 23.

  Here, when an error occurs in the operation state of the elevator 11, that is, when an error signal is included in various signals obtained from the control panel 21 (Yes in Step S13), the control unit 33 First, referring to the alert management table 34a, it is determined whether or not the error is a subject of alert determination (step S13).

  If the error is not subject to notification determination (No in step S14), the control unit 33 outputs a notification permission signal to the monitoring device 22 (step S17). As a result, an error is issued from the monitoring device 22 to the monitoring center 12 via the communication network 13. In response to this notification, the monitoring center 12 displays an error on the monitoring screen and then responds by dispatching maintenance personnel to the site as necessary.

  On the other hand, when the error is a target of the report determination (Yes in step S14), the control unit 33 determines the necessity of the report based on the environmental coefficient set in the report management table 34a ( Step S15). As a result, when it is determined that the notification is necessary (Yes in Step 16), the control unit 33 outputs a signal to permit the notification to the monitoring device 22 regarding the error (Step S17).

  If it is determined that there is no need for reporting (No in step 16), the control unit 33 outputs a reporting prohibition signal to the monitoring device 22 regarding the error (step S18). As a result, the monitoring device 22 cancels the notification by discarding the error itself.

  Here, it demonstrates concretely using FIG.

  Now, it is assumed that the specified time for the opening / closing operation of the car door 30 is 5 seconds. Normally, if the door opening or closing is not completed within 5 seconds when the car 26 is landed, the monitoring device 22 determines that the door is abnormal and issues a notification to the monitoring center 12.

  As shown in FIG. 3, when “door abnormality” is set as a monitoring target in the alert management table 34a of the agent device 23 together with its environmental coefficient K1, when the “door abnormality” occurs, the environmental coefficient K1. Based on the above, the necessity of reporting is determined.

  In this case, the environment coefficient K1 is set to a high value in an environment such as an office building where dust or the like hardly adheres to the groove of the car door 30 and the car door 30 opens and closes smoothly. . If the coefficient value is high, the criterion of the notification determination becomes high accordingly, and if the opening / closing operation of the car door 30 is not completed within 5 seconds of the specified time, the “door abnormality” is notified.

  On the other hand, if the environment is such that the car door 30 does not open and close smoothly, for example, such as in a multi-purpose building or factory, the environment door K1 is set to a low value. Is done. If the coefficient value is low, the criterion of the report determination becomes low accordingly. Therefore, even if the opening / closing operation of the car door 30 is not completed within 5 seconds of the specified time, the “door abnormality” is not notified.

  In this way, when an error occurs in the operation state of the elevator 11, the notification at that time is controlled based on the environmental coefficient that differs for each property, so that it is possible to suppress the notification with low urgency as much as possible. As a result, the communication line of the monitoring center 12 can be relaxed, and it becomes possible to preferentially deal with highly urgent notifications.

  In the process of FIG. 4, when it is determined that there is no need to issue a notification (No in step S <b> 16), if the same error has occurred a predetermined number of times or more within a certain period, the monitoring device 22 is notified. May be instructed. This is done by managing the monitoring target determined to be unnecessary and its error count in the alert management table 34a, etc., and adding a process of reporting when the error count reaches a predetermined number within a certain period. Can be realized.

  In FIG. 3, “door abnormality” has been described as an example of the monitoring target of the agent device 23, but the same applies when other monitoring targets are set. The monitoring target of the agent device 23 can be set for each property by a command of the monitoring center 12, and the environmental coefficient can also be set for each property by the monitoring center 12.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
