Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation monitoring device that displays an operation state of a group management elevator on an image display device.

[Conventional technology]

When a plurality of elevators are installed in one building (building), group management control is performed to operate these elevators efficiently. In this case, in order to judge the suitability of the operation management of the group management elevator, for example, as disclosed in Japanese Patent Application Laid-Open No. 60-161878, the operation map of the elevator recording the car position of the elevator that changes over time (FIG. 10 described in the above-mentioned publication), or means for measuring a waiting time from when the hall button is turned on to when the elevator arrives and when the hall button is turned off is used. Then, it is determined whether the car is mechanically traveling as scheduled by looking at the change in the mutual interval between the elevators from the measured operation map of the elevator.

[Problems to be solved by the invention]

As shown in FIG. 10 of the above-mentioned publication, the operation chart in the above-mentioned prior art is such that a single chart shows the car positions of all elevators and the lapse of time of the operation state of the call button. Therefore, when the number of elevators and the number of hall calls increase, the drawing becomes very complicated, and it is difficult to analyze the operation state in a short time. In particular, even if an elevator engineer explained this operation map to the building manager, it was difficult to grasp the movement of the car directly and it was very difficult to understand.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems in the prior art described above, and display the operating status of an elevator on an image display device in a moving image, so that not only a specialist engineer but also a general building manager and an elevator can be used. It is an object of the present invention to provide an elevator operation monitoring device that allows an operator to easily understand the operation state of the elevator.

[Means for solving the problem]

In order to achieve the above object, according to the present invention, in a plurality of elevators that are group-managed based on operation status data, at least hall call data, car call data, and status data of each elevator car are extracted from the operation status data. Data collection means, and data file creation for setting items according to the data generation status for each of the data, classifying the data collected by the data collection means into the corresponding items, and creating a data file for each data Means, image file creating means for creating an overall operation state at a certain time based on the data stored in each of the data files in an image file at predetermined time intervals, and based on the data stored in the image file. Display means for displaying an image is provided.

[Action]

According to the present invention, at least hall call data, car call data, and state data of the operation status data of the elevator are collected, a data file is created, and the image file is displayed at predetermined time intervals using the data file. By creating an image file for convenience and displaying the data of the image file on the image display device, it is possible to watch the movement of the car and the display state of the call button and the like in a moving image.

〔Example〕

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

FIG. 1 is a block diagram of an elevator operation monitoring device according to an embodiment of the present invention. In the figure, E indicates an elevator system, and n parallel elevators are installed. 1 is a group management control device for allocating the generated hall call to an appropriate elevator among the n units, 2 _I to 2 _n
Is an elevator control device that controls the traveling of the corresponding elevator according to the assigned hall call and car call. 3 is a data collection / recording device, 4 is a data analysis / processing device, 5 is a plotting device, 6 is an image display device,
These constitute an elevator operation monitoring device (hereinafter simply referred to as a monitoring device). Details of this monitoring device will be described later.

Here, the overall operation will be briefly described. The monitoring device is the group management control device 1 of the elevator system E.
Connected via a serial data communication line or a parallel data communication line, and when the power of the monitoring device is turned on, the measurement is started, and the group management control device transmits the hall call data, each elevator at a certain period, for example, every 50 ms. controller 2 ₁ to 2 _n
, And transmits car position and state data (car state data such as door state, direction, and car weight), car call data, and assigned hall call data to the data collection / recording device 3. In the data collection / recording device 3, based on the transmitted data, for each data of the hall call data, the allocated hall call data, and the car call data, the floor where the call is generated, the generation time, the duration, and the like are calculated. Then, they are recorded in the hall call data file, the assigned hall call data file, and the car call data file, respectively. Further, the car state data is recorded in a car state data file. At this time, various recording media such as a magnetic tape, a magnetic disk, and a RAM (read-write rewritable storage element) can be used.

At the end of the measurement or after an arbitrary time, the four data files are input from the data collection / recording device 3 to the data analysis / processing device 4. In the data analysis / processing device, the hall call data file, the assigned hall call data file, the car call data file, and the car state file input from the data collection / recording device 3 are used.
Elevator operation diagram data is created and output to a plotter 5 such as a printing device or an XY plotter to draw an elevator operation diagram. Separately, from the four data files, for each time within the measured time, the state of each hall call, the allocated hall call, the car call, and the car state of each elevator car are graphically displayed on the same screen. Are continuously created and recorded at predetermined time intervals, for example, every second. When the operation status of each elevator is reproduced on the image display device 6, the reproduction screen files created by the data analysis / processing device 4 are sequentially read, for example, one by one, and the contents are displayed on the image display device. 6 is transmitted. Thereby, the operation status of each elevator is displayed on the image display device 6.

Next, the details of the processing performed by the data collection / recording device 3 and the data / analysis processing device 4 in FIG.
This will be described with reference to FIGS.

First, the processing contents of the data collection / recording device 3 will be described with reference to FIG. FIG. 2 is a data flow diagram showing what kind of data the operation status data of the elevator created by the group management control device 1 is converted and recorded by the data collection / recording device 3. 101T indicates operation status data held in the group management control device 1. This operation status data 10
1T has UP hall call data 101a and DOWN hall call data 101b common to the first to n-th elevators, and has predetermined data for each of the first to n-th elevators. For example, when this is viewed on the first machine, car position data 101c, car state data 101d, car call data
101e, UP allocation hall call data 101f, DOWN allocation hall call data 101g, and the like. In each of the above data, the common data 101a and 101b, the car call data of each car, the UP allocation hall call data, and the DOWN allocation hall call data, each floor corresponds to one bit of the memory, and when there is a call, It is composed of a data table (referred to as bit-type data) in which one byte of data is collected on the 8th floor, which is "0" when there is no call, and the number of floors is collected. The position data, the car state data, and the like are constituted by data stored in one byte and representing numerical values (referred to as numerical data).

The operation status data 101T is input to the data reception circuit 31 of the data collection / recording device 3 via the data transmission circuit 11 of the group management control device 1 at a fixed period, for example, every 50 ms. In the data recording circuit 32, the data of the operation status data 101T input to the data receiving circuit 31 is referred to the time data output from the clock 33, and the hall call data file 301 is referred to.
T, cumulatively recorded in the assigned hall call data file 302T, the car call data file 303T, and the car state data file 304T.

Here, the contents of the file will be described with reference to the allocation hall call data file 302T among the above files. The allocated hall call data file 302T includes “direction”, “unit number”, “occurring floor”,
Items such as “occurrence time” and “duration” are set. For example, at 10:20:35, call the UP hall on the 6th floor 2
The case where the hall call is serviced by the second car after 20 seconds has been allocated to the car is exemplified. In this case, the bit corresponding to the sixth floor of the UP allocation hall call data in the second unit of the operation status data 101T changes from “0” to “1”,
Also, at the end of the assigned hall call data file 302T,
The direction (UP), the machine number (2), and the occurrence floor (6) occurrence time (10:20:35) are recorded, and a duration counter (not shown) starts counting. When the second unit arrives at the sixth floor, the bit corresponding to the sixth floor of the second unit in the traffic status data 101T becomes “0”, the duration counter stops counting, and this count value is stored in the allocated hall call data file 302T. Recorded in the Duration section. Similarly, predetermined items as shown are set in the hall call data file 301T and the car call data file 303T, and data is sequentially recorded in the items corresponding to each call generation and reset. The same applies to the car state data file 304T. Here, the car state data file 304T stores the car number, the car position, the car state, and the time every time the car position and the car state change, so that the memory capacity can be saved, but the unit time, for example, every one second It may be recorded.

As described above, the recording to each of the data files 301T to 304T is repeated, and when the measurement is completed, or after an arbitrary time has elapsed, each of the data files 301T to 304T is transmitted to the data transmission circuit.
34, the respective data files 401T to 40T of the data analysis / processing device 4 via the data receiving circuit 41 of the data analysis / processing device 4.
Transfer to 4T.

Next, the processing contents of the data analysis / processing unit 4, that is, the elevator operation status reproduction screen file creation processing is described in the third section.
This will be described with reference to the drawings. In Figure 3, 420T ₁ ~420T _m is a fixed time interval, a playback screen file of a screen for reproducing and displaying, for example, every one second. Uses a playback screen file 420T _o as reproduction start 0 th second display data in the present embodiment, hereafter sequentially reproduced screen file 420T ₁ ~420T _m-1 Yuki create a playback screen as the reproduction start m sec th display data Create a file 420T _m . Each of the playback screen files 420T _{o to} 420T _m has a matrix configuration of the memory. One row in the horizontal direction represents the data of the first floor, and the first column of each row has an UP.
Hall call duration data, UP hall call data in the second column, car 1 status data or 1 in the third column
No. car call data, No. 1 assigned hall call data in the fourth column, No. n car status data or No. n car call data in the first + n × 2 columns, No. n allocated hall in the second + n × 2 columns Call data, next column
DOWN hall call data, the next column stores DOWN hall call data, and the next column stores DOWN hall call duration data. Therefore, each of the reproduction screen files 420T _{o to} 420T _m has a data array of 20 rows × 20 columns when the service floor of the elevator is, for example, 20 floors and the number of elevators is 8 in parallel.

Next, the procedure for creating the playback screen files 420T _{o to} 420T _m based on the respective data files 401T to 404T is performed by setting the playback start time to 10: 00: 0 seconds, the playback end time to 10: 1: 0 seconds, The case where the time interval is 1 second will be described as an example. First, data whose hall call occurrence time is between 10:00:00 and 10: 01: 0 is searched from the hall call data file 401T. For example, if 10 hours, 0 minutes, 19 floor DOWN hall call to 0 seconds is to have occurred, the playback screen file 420T mean this in a column of DOWN hall call data of the corresponding line on the 19th floor of the _o "▽" mark 4a character of In addition to writing the code data, the data corresponding to 0 seconds is written in the DOWN hall call duration data column on the same line. Next, assuming that the duration of the DOWN hall call is 23 seconds, the playback screen file
420T _{1 to} 420T ₂₃ "▽" mark 4a is sequentially and sequentially written in the row of the DOWN hall call data of the same row (row corresponding to the 19th floor) of the same row (row corresponding to the 19th floor), and one second of the row of the same row DOWN hall call duration data, Data corresponding to each number of seconds from 2 seconds to 23 seconds is sequentially and sequentially written. Such processing is performed for all hall call data whose occurrence time in the hall call data file 401T is included in the reproduction time zone.
Similarly, data within the playback time zone is searched from the assigned hall call data file 402T and the car call data file 403T, and a process of writing data to the playback screen files 420T _{o to} 420T _m is performed.

Next, an example of performing conversion into playback screen file 420T _m from the car status data files 404t. The car state data file 404T includes a machine number as shown in FIG.
Car position, car condition (eg direction, door open / closed state,
Each data of time, etc. as one block
The data is written at regular time intervals, for example, every second. In this case, the time data in the car status file 404T included in the reproduction time zone is searched, and at the same time, each data such as the car number, the car position, and the car status included in the same block is read. From the time data, a corresponding one of the playback screen files 420T _{o to} 420T _m to be recorded is selected, a line to be written in the playback screen file is obtained from the car position data, and a column to be written is obtained from the machine number data. Is obtained and the car state data is written at that location.
At this time, as the data indicating the car state, in the example shown in FIG. 3, a “□” mark indicating the car position and a “↑” mark or “↓” mark indicating the direction are superimposed and expressed. However, when the open / closed state of the door, the weight in the car, and the like are further expressed at the same time, the operation status of the elevator can be more easily understood. As described above, a screen reproduction file is created from each of the data files 401T to 404T for all reproduction time zones.

Next, screen reproduction will be described. At the time of screen reproduction, a screen reproduction file created by the data analysis / processing device 4 is used.
420T _{o to} 420T _m are read out, and the above-mentioned data stored therein are continuously transferred to the image display device 6, and the operation status of the elevator is reproduced. At this time, since the image reproduction files 420T _{o to} 420T _m are created over the entire time of the screen reproduction time zone, the data analysis / processing device 4
By changing the speed and order of reading image playback files, it is possible to perform various screen playback according to the purpose at the time of analysis of elevator operation status such as slow playback, still playback, reverse playback, fast forward playback, etc. .

FIG. 4 is a diagram showing an example of a reproduction screen. Play screen 61
, Floor numbers are arranged vertically and elevator numbers are arranged horizontally, so that the operation status of the elevator can be easily grasped visually. In the upper right part of the playback screen, the time 61g during playback is displayed. Also, in order from the left end of the playback screen, each floor display 61h, UP hall call duration display 6
1i, UP hall call display 61a, car status display 61f, car call display 61e, UP allocation hall call display 61c, DOWN allocation hall call display 61d, DOWN hall call display 61b, DOWN hall call duration display 61j .

In the above-described reproduction screen creation, the car state data file 404T is used for saving the above-mentioned memory, and in order to save the memory, the car number, car position, car state, and time data of one block each other than the time data are excluded. It is also possible to record each time one changes. An example of a preparation method of reproducing screen file 420T _m in this case, FIG. 5 (a), is described with reference to (b). FIG. 5A is a graph showing the movement of the elevator, and FIG. 5B is a diagram showing a reproduction screen. As described above, if the car state data file 404T is recorded every time a certain data changes, the actual movement of the elevator is such that the operation locus is continuous as shown by the line 4d as shown in FIG. 5 (a). Despite being summer in manner, since the car status data files 404t, only two points of the car state change point 4P _1, 4P ₂ is not recorded,
In the playback screen on the car status 4d _1, as shown in dashed lines in FIG. 5 (b), a certain time, so that the display does not match the actual elevator movement is made. In order to correct this, when a reproduction screen file is created, the following processing is performed. That, t ₁ the time of the change point 4P ₁ of the car state, f ₁ the cage position, the time of t ₂ of the change point 4P ₂ of the car conditions, the car position and f _2, the time on the reproduction screen files t, Assuming that the car position on the playback screen is f, the following equation holds.

A value obtained by rounding off the cage position f on the playback screen obtained by the above formula as a car position on the reproduction screen files, play for until time t ₂ at time t ₁ Karakago state change point 4P ₂ cage state change point 4P ₁ Write to the playback screen file every unit time. As the car status 4d ₂ of the playback screen shown by the solid line in Figure 5 by the process (b), the playback screen close to the actual elevator movement is obtained.

〔The invention's effect〕

As described above, in the present invention, data on the operation status of the elevator is collected, created in a file, a screen reproduction file is created at predetermined time intervals using this file, and this data is sent to the image display device. Since the display is made, the movement of the car and the state of the hall call button etc. can be seen in a moving image, which makes it easy for non-technical engineers, for example, building managers, etc., to understand the operation status of the elevator. You can do it. In addition, since image reproduction can be performed at actual speed, slow reproduction, reverse rotation, and the like, there is an effect that the movement of the group management elevator can be easily analyzed.
