BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for monitoring the operating state of an elevator and the inside of a car.
[0002]
[Prior art]
Conventional elevator monitoring devices perform separate operation of elevator operation monitoring and in-car monitoring.
However, in a system in which these functions are performed by individual devices, it is necessary to start up the devices for each function and operate them separately. That is, when it is desired to grasp the driving state of the car, the operation monitoring device is used, and when it is desired to check the state of the car at that time, the car monitoring device is used.
In this way, in a system in which each function is performed by an individual device, it is necessary to prepare a dedicated personal computer for each monitoring device, for example, and it is also necessary to prepare a dedicated monitor for in-car images. there were. For this reason, a large installation space was required.
In addition, when an abnormality occurs in the elevator, in the case of a system that receives the video in the car together with the reception of the abnormality information, in order to grasp both situations at the same time, an attendant is arranged on each monitor screen There was a problem in terms of labor costs.
Therefore, the conventional elevator monitoring device records a monitoring video by installing a monitoring camera in the car, and records the monitoring video in association with the operating state and date / time information detected from the elevator control device, When replaying surveillance video, you can select the necessary information from the elevator operating status and date / time information and display it in combination on the screen, or select a specific operating status from the recorded surveillance video. The matching monitoring video is detected and displayed (for example, see Patent Document 1).

[Problems to be solved by the invention]
As described above, the conventional elevator monitoring device requires a large space for installing the monitoring device in a system in which the operation monitoring of the elevator and the monitoring in the car are performed separately. In addition, it is necessary to place a staff member for each monitor of each monitoring device, which causes a problem in cost.
On the other hand, in a conventional elevator monitoring device that displays a combination of elevator operation monitoring and in-car monitoring, the installation location is always fixed at a fixed location because it is directly connected to the elevator control device and monitoring camera. Is done. For this reason, when changing the installation location of the elevator monitoring device, a signal line must be laid again from the elevator control device.
By the way, the installation location of the elevator monitoring device is determined by the building management system. If the management system changes, the installation location also changes. For example, in an office building, the doorway of the building changes between daytime and nighttime, and the management system also changes. That is, at night, it is managed together with other building facilities by a small number of guards. The installation location of the elevator monitoring device may change according to the change in the management system.
Also, the elevator monitoring system itself may change based on the building management rationalization plan.
As described above, when the building management system changes, the conventional elevator monitoring device must be newly laid with a signal line between the elevator control device, which is expensive and time-consuming for the laying work. There was a problem that the monitoring period was long.
[0005]
The present invention has been made to solve the above-described problems, and it is an object of the present invention to improve security in a closed room in a car, reduce the installation space of the apparatus, and reduce the cost of monitoring work.
It is another object of the present invention to provide an elevator monitoring device that can easily cope with a change in an elevator monitoring location accompanying a change in a building management system.
Furthermore, it aims at providing the monitoring apparatus of the elevator which can expand a monitoring place easily.
It is another object of the present invention to detect an abnormal condition at an early stage by displaying an elevator operation state at the same time and an in-car image together.
[0006]
[Means for Solving the Problems]
The elevator monitoring apparatus according to the present invention includes: driving state data in which the operating state of the elevator is recorded together with the date and time at predetermined time intervals; and in-car video data in which a video in the car related to the operating state data is recorded. The monitoring server centrally records and manages the monitoring server, and the monitoring server is connected to a computer network. Further, the monitoring terminal device is connected to the computer network to display the operation state data and the in-car video data on the monitor. It is what I did.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
1 to 16 show an elevator monitoring apparatus according to Embodiment 1 of the present invention.
FIG. 1 is a block diagram showing the overall configuration of an elevator monitoring apparatus. In the figure, a plurality of elevators 1 are installed, and all of them are monitored. The elevators constitute a bank that is group-managed for a predetermined number of elevators. Each elevator control device 2 is assigned management numbers E001, E002 to En to EN (hereinafter collectively referred to as En), and each elevator 1 can be specified by the management number En. A camera 5 is attached to the car 3 so that an image in the car 3 including the door 3a can be taken.
[0008]
The elevator control device 2 is connected to the data conversion means 12 via the transmission line 11, and outputs the operation state data shown in FIG. 3, that is, the management number En, the bank name, the car position, and the like. The data conversion means 12 aligns signals from the elevator control devices 2 in a predetermined format. In other words, when the elevator manufacturers are different, the signal format is different when the elevator model or manufacturing date is different even if the same manufacturer. Therefore, the signal format is made uniform by the data conversion means 12. The data conversion means 12 is connected to the monitoring server 20 via the transmission line 13 and transmits the operation state data from each elevator control device 2 to the monitoring server 20. Further, the video in the car 3 photographed by the camera 5 is also transmitted to the monitoring server 20 through the transmission path 13.
[0009]
The monitoring server 20 receives the driving state data from each elevator control device 2 and the in-car image from the camera 5 through the input / output circuit 21 at a constant time interval, for example, every second.
The recording control means 22 reads the operating state data received via the input / output circuit 21 with reference to the system parameter table 23 (details are shown in FIG. 2) and reads the bank name corresponding to the management number En. The memory address is designated and sent to the operation state recording means 24. The operation state recording means 24 records the operation state data in a predetermined format at a specified memory address in the monitoring data table 25 (details are shown in FIG. 3).
[0010]
The recording control means 22 reads the current date and time from the clock 26 and sends it to the date / time recording means 27. The date and time recording means 27 records the date and time in a predetermined format as a part of the operation state data at the designated memory address of the monitoring data table 25.
Further, the recording control means 22 generates the video code Gi in association with the memory address (En + i) of the in-car video data 29a received via the input / output circuit 21, and for the in-car video data 29a. The memory address (En + Gi) is designated and sent to the car video recording means 28. The in-car video recording means 28 records the video code Gi in a predetermined format at a designated memory address in the monitoring data table 25. Also, the car video data 29a is recorded together with the video code Gi in the monitoring video file 29 (details are shown in FIG. 4).
[0011]
When the monitoring server 20 receives the search condition from the monitoring terminal device 40 via the input / output circuit 31, the search means 30 obtains the operation state data and the video code Gi recorded in the monitoring data table 25 according to the search condition. Further, the car video data 29 a and the video code Gi are respectively searched from the monitoring video file 29 and transmitted from the input / output circuit 31 to the monitoring terminal device 40 via the computer network 32.
[0012]
The computer network 32 is stretched around the building, and the monitoring terminal device 40 is installed at an appropriate place in the building. The search condition is input from the search condition input means 41 (details are shown in FIG. 14) of the monitoring terminal device 40. The operation state data and the video code Gi searched in the monitoring server 20 based on the search condition are received via the input / output circuit 42 and are sequentially recorded in the search data table 43 (details are shown in FIG. 5). . Similarly, the car video data 29a and the video code Gi are also recorded in the search video file 44 (details are shown in FIG. 6) in the order received.
[0013]
When a display condition for taking out data to be displayed on the monitor 48 is input by the display condition input unit 45, the display control unit 46 obtains the operation state data and the video code Gi from the search data table 43 according to the input display condition. Further, the video code Gi and the in-car video data 29a are extracted from the search video file 44 based on the video code Gi. The input / output circuit 47 transmits the operation state data, the video code Gi, and the car video data 29a to the monitor 48 for display.
[0014]

[0021]
The search video file 44 shown in FIG. 6 is based on the search conditions shown in FIG. 14, and the date and time from 7:00:00 to 8:00:00 on June 1, 2003 is read from the monitoring video file 29. The result of the search is related to the contents of the search data table 43 shown in FIG. Therefore, for the elevator with the management number E001, the car video data 29a and the video code (En + Gi) are written in the memory addresses (E001 + G1) to (E001 + G3601). The elevators with the management number E002 are the memory addresses (E002 + G1) to (E002 + G3601). The same applies hereinafter.
[0022]
Hereinafter, the operation will be described with reference to FIGS. Each operation is configured to operate in a predetermined order at regular time intervals in the monitoring server 20 and the monitoring terminal device 40.
Based on FIG. 7, the writing operation to the monitoring data table 25 and the monitoring video file 29 in the monitoring server 20 will be described.
In step S11, the management number En is initialized to the management number E001. In step S12, it is checked whether the variable i has reached the last value L. Here, the variable i indicates the memory address of the monitoring data table 25 in the previous write operation. Therefore, if the previous write was the last memory address (En + L), the variable i = 1 is set in step S13 because the current memory address (En + 1) is written this time. If it is not the last memory address (En + L), the process proceeds to step S14, where the variable i = i + 1 is set and the previous next memory address (En + i) is designated.
[0023]
In step S15, the bank name of the elevator having the management number En is read from the system parameter table 23. In step S16, the date and time are read from the clock 26 and recorded in the memory address (En + i) of the monitoring data table 25, respectively. . In step S17, the management number En, car position (floor 4), operation direction, door 3a opening / closing, operation suspension, normal / abnormal, and video code Gi are recorded in the memory address (En + i) of the monitoring data table 25. To do. Here, the video code Gi is assigned in relation to the variable i. Further, when it is necessary to distinguish the elevator, the video code Gi is combined with the management number En and represented by a code (En + Gi).
[0024]
In step S18, the car video data 29a is photographed by the camera 5 and written to the monitoring video file 29 together with the video code (En + Gi). If the last management number EN has been written in step S19, the process ends. If not, the process is repeated from step S11 for the next management number En in step S20.
Here, the variable i remains as it was when the last management number EN elevator was written. Therefore, the next writing is continued from the memory address (En + i) written last by S14, and further, the initial value is set by step S13 to be circulated and overwritten.
[0025]
The basic operation of the monitoring terminal device 40 will be described with reference to FIG.
When the monitoring terminal device 40 is started up, the monitor 48 becomes an initial screen shown in FIG. In step S31, when the mouse pointer 48e is moved to the search button 48a and clicked (hereinafter referred to as “pointing”) in step S31, the process proceeds to the process shown in FIG. 9, and the search condition is input. When the monitor button 48b is pointed in step S32, the process proceeds to the process shown in FIG. 12, and the retrieved data is displayed on the monitor 48. When the end button is pointed in step S33, the monitor 48 returns to the initial screen shown in FIG. 13 and ends the process in step S34.
[0026]
Based on FIG. 9, the search condition input operation from the monitoring terminal device 40 will be described.
When the search button 48a is pointed in step S31 of FIG. 8, the process proceeds to step S50, and the search data table 43 and the search video file 44 are cleared. In step S51, the monitor 48 becomes a search condition input screen shown in FIG. In step S52, when the search start date and time and search end date and time as search conditions are input and the OK button is pointed, in step S53, the search is sent to the monitoring server 20 and the process is terminated.
If the search condition is not input in step S52, the process proceeds to step S54, and the process ends when the end button 48c is pointed. If pointing is not performed, the process is terminated while waiting for input.
[0027]
FIG. 10 shows a search operation in the monitoring server 20, which responds to the search condition input by the monitoring terminal device 40.
When the search start date and time and the search end date and time are received in step S61, the variable i is specified from the memory address (E001 + i) of the monitoring data table 25 in which the date and time matching the search start date and time is recorded in step S62, and the value is set. Write to variable js. Similarly, in step S63, the variable i of the search end date and time is specified, and the value is written in the variable je. In step S64, the management number En is initialized to E001. In step S65, the variable j is initialized to js.
[0028]
In step S66, the operating state data and the video code Gj recorded in the memory address (En + j) of the monitoring data table 25 are transmitted to the monitoring terminal device 40. In step S67, the car video data 29a and the video code Gj recorded in the memory address (En + Gj) of the monitoring video file 29 are transmitted to the monitoring terminal device 40. Thereafter, the variable j is incremented through step S68 and step S69, and the search is sequentially performed until the search end date and time, and the search result is transmitted to the monitoring terminal device 40. If the variable j becomes the variable je in step S68, the data recorded in the memory addresses (En + js) to (En + je) of the monitoring data table 25 and the monitoring are performed for the next management number En via the steps S70 and S71. The data recorded in the memory addresses (En + Gjs) to (En + Gje) of the video file 29 are sequentially retrieved and transmitted to the monitoring terminal device 40. When the last management number EN is retrieved and transmitted, the processing ends.
The variable j is used instead of the variable i because the variable i is a value indicating the memory address (En + i) last written in the monitoring data table 25 by data collection, and the value is held. is there.
[0029]
FIG. 11 shows an operation of writing search data to the search data table 43 and the search video file 44 in the monitoring terminal device 40.
In step S80, when the monitoring terminal device 40 receives the search result transmitted from the monitoring server 20, in step S82, the management number En and date / time are read from the received search data, and the search start date / time is set to the variable i = 1. The search date variable i is calculated, and the memory address (En + i) of the search data table 43 is designated. In step S83, the operation state data and the video code Gi are written to the designated memory address (En + i) in the search data table 43.
[0030]
In step S84, the memory address (En + Gi) of the search video file 44 is designated. In step S85, the car video data 29a and the video code Gi are written in the memory address (En + Gi) of the search video file 44. When the search end date / time is written, the process proceeds from step S86 to step S87, and the process ends after writing up to the last management number EN.
FIG. 5 shows the search data table 43 in which the driving state data and the video code Gi are written, and FIG. 6 shows the search video file 44 in which the car video data 29a and the video code Gi are written.
[0031]
FIG. 12 shows a process for displaying the search data on the monitor 48.
It is assumed that search data is written in the search data table 43 and the search video file 44, and the screen of the monitor 48 is in the state shown in FIG. When the monitoring button 48 is pointed, the process proceeds from step S32 in FIG. 8 to step S90 in FIG. In step S90, the display condition input means 45 shown in FIG. The display condition input means 45 can designate the date and time to be displayed, the bank name, the car position, the operation stop, the normal abnormality, and the display format. Each specified item shall be weighted.
[0032]
When the display condition is designated, the process proceeds from step S91 to step S92. Here, as shown in FIG. 15, an example is shown in which the display date and time (June 1, 2003 7:30:30) and the first bank are specified.
If the display format is “fixed” and the OK button is pointed as shown in FIG. 15, the process proceeds from step S92 to step S93. In step S93, the operation state data at the designated display date and time is displayed on the monitor 48. The outline is shown in FIG. That is, the car position is displayed at a position on the vertical axis.
If the display format is “move ahead” and the OK button is pointed, the process moves from step S92 to step S94. In step S94, the designated display date / time is switched to the start date / time, and the operation state data of the previous date / time is sequentially displayed on the monitor 48.
When the display format is “backward movement” and the OK button is pointed, the process proceeds from step S92 to step S95. In step S95, the designated display date / time is switched to the start date / time, and the operation state data of the later date / time is sequentially displayed on the monitor 48.
[0033]
When the position of the car on the monitor 48 is pointed, the car video data 29a and the video code (En + Gi) are additionally displayed on the monitor 48. FIG. 16 illustrates a case where the car position with the management number E001 is pointed. When the display format is “move forward” and the car position is pointed, the data contents at the date and time after switching are sequentially displayed along with the switching of the display date and time, including the in-car video data 29a and the video code (En + Gi). Switched and displayed.
The same applies to the case where the display format is “move backward”, and the display date and time are switched, and the data contents at the date and time after switching are sequentially displayed. Therefore, when the current date and time is input by the search condition input unit 41 shown in FIG. 14 and “replacement” is set by the display condition input unit 45 shown in FIG. 15, the latest data captured in the monitoring server 20 is stored. It is displayed on the monitor 48. That is, the driving state data and the car video data 29a can be displayed in real time.
[0034]
According to the first embodiment, the operation state data in which the operation state of the elevator 1 is recorded together with the date and time at a predetermined time interval is associated with the in-car image data 29a recorded simultaneously with the recording of the operation state data. The monitoring terminal device 40 is connected to the monitoring server 20 via the computer network 32, and the data recorded in the monitoring server 20 is displayed on the monitor 48. Thus, since the elevator 1 is monitored, the in-car image can be monitored according to the operation state of the elevator 1. For this reason, by monitoring the video in the car at the designated date and time, it is possible to improve security in a closed room in the car and also to monitor with a single device, so that the installation space can be reduced. it can. As a result, the staff is also labor-saving, so that the cost of monitoring work can be reduced.
Further, since the data recorded in the monitoring server 20 can be retroactively displayed on the monitor 48, the abnormal state and the cause of the abnormality can be discovered early.
In particular, since the monitoring terminal device 40 may be connected to the computer network 32, the monitoring terminal device 40 may be connected to the existing computer network 32 installed at a new monitoring location even if the monitoring location changes. . For this reason, it is possible to easily cope with fluctuations in the building management system. The unmonitorable period can be shortened.
[0035]
Further, even when the number of monitoring locations is increased, it can be easily handled in the same manner.
Furthermore, since the conditions for searching the data recorded in the monitoring server 20 are also input from the monitor 48, the elevator monitoring device can be made compact.
Furthermore, since the operation state data and the in-car image data 29a taken from the monitoring server 20 to the monitoring terminal device 40 are displayed on the monitor 48 sequentially by switching the date and time to be displayed, it can be displayed in a wide time zone. You can monitor it.
Furthermore, since the car image data 29a is displayed on the monitor 48 when the position of the car displayed on the monitor 48 is pointed, the elevator operating state and the car image at the same time can be displayed together. It was possible to improve the monitoring.
[0036]
In the first embodiment, the search condition input means 41 is only the date and time as shown in FIG. 14, but the search condition input means 41 is not limited to this. It is also possible to do. Since the concrete content which implements it can be easily guessed from the said Embodiment 1, the detail is abbreviate | omitted.
[0037]
