  According to the present invention, it is possible to collect and analyze data of a portion that should be monitored in detail according to the property, without a maintenance worker going to the site.

  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 on which a CPU, a ROM, a RAM, and the like are mounted.

  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, 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 transmits them to the monitoring center 12. The agent device 23 is individually provided for each property (for each elevator, for each model, etc.) as a high-performance monitoring device, and the monitoring function can be arbitrarily changed by a command from the monitoring center 12.

  In the present embodiment, the agent device 23 selectively collects data related to the measurement target arbitrarily set by the monitoring center 12 from the control panel 21 and analyzes the data as necessary. 22 to transmit 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 includes a data collection unit 33a, an abnormality determination unit 33b, and a notification unit 33c.

  The data collection unit 33a performs data collection processing related to the measurement target set by the monitoring center 12. The abnormality determination unit 33b detects the presence / absence of an abnormality by comparing the data collected by the data collection unit 33a with the reference data of the measurement target. The reporting unit 33c performs a reporting process for the monitoring center 12 when an abnormality is detected by the abnormality determination unit 33b.

  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 measurement table 34 a for storing the measurement target set by the monitoring center 12 and the reference data of the measurement target.

  FIG. 3 shows an example of the measurement table 34a.

  In this case, “motor torque” and “car load” are set as measurement targets. “Motor torque” is a torque signal for rotating the motor 24 a installed in the hoisting machine 24. The “car load” is a load signal detected by a load sensor 29 installed in the car 26.

  Further, as reference data for these measurement objects, a waveform of a torque signal and a waveform of a load signal obtained at normal time are set. This reference data is determined according to the specifications of each part for each property.

  In such a configuration, in order to perform special monitoring according to the property, a command is issued from the monitoring center 12 to set an arbitrary measurement target in the agent device 23. The agent device 23 collects data related to the set measurement target and transfers it to the monitoring center 12. At this time, not only data is collected, but also processing such as determining whether there is an abnormality during data collection and reporting to the monitoring center 12 is performed.

  Hereinafter, the processing operation of the gent device 23 will be described in detail.

  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, the measurement target set individually for each property from the monitoring center 12 and the reference data for the measurement target are sent to the elevator 11 via the communication network 13. The measurement target and reference data are given to the agent device 23 via the monitoring device 22 having a communication function.

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

  Thereafter, the control unit 33 selectively collects data related to the measurement target set in the measurement table 34a from the control panel 21 of the elevator 11, and records the data in a predetermined area in the storage unit 34 (step). S13). At that time, the presence or absence of abnormality is determined by comparison with the reference data of the measurement target (step S14).

  If no abnormality is detected during data collection (No in step S14), the control unit 33 reads and monitors a series of data recorded in the storage unit 34 at a predetermined timing such as weekly or monthly. The data is transferred to the monitoring center 12 via the device 22 (step S17).

  On the other hand, if any abnormal operation is detected during data collection (Yes in step S14), the control unit 33 notifies the monitoring center 12 of that fact (step S16) and notifies the monitoring center 12 of that fact. In order to analyze the cause of the abnormality, the measurement target data collected up to that point is transferred to the monitoring center 12 (step S17). For example, when the monitoring center 12 receives a predetermined number of reports within a certain period of time, the measurement target is managed as a readjustment item, and a maintenance staff is dispatched to the site to perform adjustment work.

  Here, it demonstrates concretely using FIG.

  The agent device 23 takes in the torque signal of the motor 24 and the load signal of the load sensor 29 from the control panel 21 with reference to the measurement table 34 a. At this time, these signal waveforms are compared with the reference waveform at the normal time to determine whether or not an abnormality has occurred. If there is a difference of a predetermined amount or more from the reference waveform, it is determined that there is an abnormality and is reported to the monitoring center 12.

  In this case, if there is an abnormality in the torque waveform, the ride comfort is affected, for example, the car 26 vibrates when the elevator 11 is traveling. Therefore, when the monitoring center 12 receives the report of the torque abnormality from the agent device 23, the maintenance center is dispatched to the site to perform the adjustment work of the motor 24a.

  Further, if there is an abnormality in the waveform of the load signal, the car 26 cannot be accurately positioned at the time of landing, and a step is generated between the platform and the landing. Therefore, when the monitoring center 12 receives the report of the load abnormality from the agent device 23, the maintenance center is dispatched to the site to perform the adjustment work of the load sensor 29.

  At this time, the monitoring device 22 mounted on the elevator 11 constantly monitors the operation state of the elevator 11 including the motor torque and the car load. However, the monitoring device 22 merely detects the presence / absence of a signal output or the output of an abnormal value. Like the agent device 23, the monitoring device 22 collects data at a location set as a measurement target or during the collection. It does not have a function to make an abnormality judgment against the reference data.

  In this way, by providing the agent device 23 individually for each property for the elevator 11 to be monitored, the property such as the motor torque state in the A property, the car door state in the B property, etc. Therefore, the monitoring center 12 can easily obtain and analyze the data of the location requiring monitoring, without the maintenance staff going to the site. As a result, for example, it is possible to quickly grasp and cope with the replacement time of parts.

  Further, if any abnormality is detected during the data collection of the agent device 23, the monitoring center 12 can quickly deal with the problem because it is immediately issued.

  In FIG. 3, the case where “motor torque” and “car load” are set as measurement objects has been described as an example, but the same applies to cases where other measurement objects are set.

  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.
