DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation monitor for monitoring the operation state of an elevator.

[0002]

2. Description of the Related Art Generally, in a building in which a plurality of elevators are arranged side by side, group management control is performed in order to operate these elevators efficiently. In such a building, traffic measurement is usually performed after the opening of the building to ascertain the operating status of the elevator or to ascertain the status of the complaint based on a complaint from an elevator user who is an end user. Here, traffic measurement means collecting and recording hall calls and elevator car status (driving direction, car position, etc.), and after the measurement is completed, the average non-response time of the elevator, the maximum waiting time, 30 minutes.
To output statistics such as the response rate within seconds, the response rate within 60 seconds, and the operating curve indicating the operating status of the elevator, and to comprehensively grasp the operating status of the elevator in the building and examine the quality of the operating status. It is.

[0003] As a result of the traffic measurement, if the operation status of the elevator is not good, it is necessary to take some measures in the group management control. In that case, the movement of the elevator will be investigated in more detail, and what will be the cause and how to improve it will be necessary, but at that time the operation curve of the elevator and the display on the display This is the movie side.

[0004] This operation curve is based on the occurrence of hall calls and the response of the elevator to the calls (such as which car traveled from which floor to which floor, where it stopped, and to which floor). Is expressed on the paper surface, and by observing the operation curve, it is possible to grasp a rough place such as whether the operation status of the elevator in the building is appropriate or whether the elevator is performing useless movement.

[0005]

However, the information that can be expressed on the operation curve is about the hall call and the car position for each car, and the amount of information is small. The car call, the door opening / closing status, and the car load , Forecast Status (Hall Lantern Status)
There is no detailed information such as, and even if such information is obtained, it is very difficult to express all of the information on paper.

As a remedy, a system for displaying a moving image on a display has been proposed in Japanese Patent Laid-Open No. 2-188380. This is because the moving image plane on the display is an improvement of the above-mentioned operation curve, and the state of the operation of the elevator is displayed on the display in real time by a moving image.As the information amount, it is possible to obtain detailed information more than the operation curve. Although it can be done, the time required for the survey is the same as the traffic measurement time because it is displayed on the display in real time.
In the case of a weekly survey, 5 × 7 = 35 hours are spent for the survey. In general, when investigating the movement of an elevator, the trouble phenomena include a long wait (a phenomenon in which a call response time takes a predetermined value or more), a car call first arrival (a floor corresponding to an elevator other than the reserved elevator). Phenomenon mode, such as the phenomenon of arriving first on the floor, can be limited to some extent, but on the video screen on the display, enormous time is spent investigating, and
The operation curve on the paper is expressed in a special format with a small amount of information, so it cannot be practically investigated by the manager of the building management company, the maintenance of the elevator maintenance company, or the surveyor, and the elevator manufacturer's Investigation by a specialized engineer is required, and in the case of a complaint process from an end user, it takes time until the system takes countermeasures, and it is not possible to take a quick response.

[0007] The present invention has been made in view of such a conventional problem, and has a high visibility of the operation status of an elevator during a measurement period, and efficiently efficiently without the intervention of an elevator expert. It is an object of the present invention to provide an elevator operation monitoring device that enables an investigation.

[0008]

According to the first aspect of the present invention, a plurality of elevators are put into service on a plurality of floors to respond to a hall call generated. A data recording means for collecting and recording elevator information from the group management control device, in an elevator operation monitoring device for externally monitoring the operation state of the elevator, for a group management control device performing service by selecting and determining A defect recording means for searching for and recording a defect phenomenon based on the elevator information recorded in the data recording means, and an operation state before and after the defect phenomenon based on the data recording means and the defect phenomenon recording means. And a display means for selecting and reproducing a moving image plane for display.

[0009]

According to the invention corresponding to claim 1, after collecting elevator information in traffic measurement, a trouble phenomenon is searched based on the collected elevator information, and the elevator is searched only in a time zone before and after the trouble phenomenon. By reproducing a large amount of information related to the operation on a dedicated display device as a moving image plane, the operation status of the elevator during the measurement period has high visibility and can be efficiently investigated without the intervention of an elevator expert. Becomes possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention, in which 1 is an elevator group management control device, 2 to 4 are elevator single control devices, 5 is a group management control device 1 and a single control device. This is a serial transmission path used for information transmission between 2 and 4.

Reference numeral 6 denotes an operation monitoring device, which comprises a monitor control device 7, a data recording device 8, and a display device 9, which are the core of the operation monitoring device, and collects and records elevator information from the group management control device. Data recording means, a defect recording means for retrieving and recording a defect phenomenon based on elevator information recorded in the data recording means, and a defect recording means based on the data recording means and the defect recording means. A display means for selecting an operation state before and after the phenomenon and reproducing it as a moving image plane for display is configured. For the group management control device 1, the operation monitoring device 6
Are connected by a serial transmission line 10.

In recent years, small and high-performance laptop computers have been marketed, and these laptop computers have a dedicated display (plasma display, LCD display, etc.) and a built-in recording device (floppy disk, disk, etc.). Therefore, by using a laptop computer as the operation monitoring device 7, a portable and high-performance device can be obtained.

FIGS. 2 and 3 show the structure of elevator information used in the group management control device 1. FIG. Here, 3 units, 8
Considering an elevator system on a floor, a hall condition table (HCT: Hall Condition)
Table) indicates that the state of the hall call is 1 as shown in FIG.
U to 7U and 2D to 8D are assumed to be represented by a bit configuration. When the hall call is not lit, the corresponding bit = 0, and when lit, the corresponding bit = 1.

The state of the car is shown in the car state table (C in FIG. 3).
CT: Car Condition Table). CCT (0), CCT (1), CCT (2)
Are tables corresponding to the first to third elevators, respectively, and are information transmitted via the serial transmission line 5 from the single controllers 2 to 4 in FIG. Each table has, as components, a car call, a car position, a direction, a door state, a load, and a lantern state. FIG. 4 illustrates these components in more detail.

In FIG. 4, (a) shows a bit configuration of a car call, and 1K to 8K correspond to the first to eighth floors, respectively. FIG. 4B shows a bit configuration at the car position.
Each floor is represented as a binary value in the lower 4 bits. For example, “0001” is the first floor and “1000” is the eighth floor.
FIG. 4C shows a bit configuration in the direction of the car, in which the lower two bits are used to indicate non-direction, UP (up) and DOWN (down).

FIG. 4D shows the state of the door. The lower two bits are used to close the door "00" and open the door "0".
1, middle open “10”, and full open “11”. Then, the door status changes from "00" to "01" →
If the order changes from “10” → “11” → “10” → “01” → “00”, it means that the door starts to open from the door closed state, fully opens, and then closes.

FIG. 4 (e) shows the load of the car, which is given as a percentage of the rated load of the car expressed as a binary value. For example, 65% is "41
(H) "(= 01000001), and 45% is" 2
D (H) "(= 100101101).

FIG. 4F shows the lantern state of the hole, and the lower two bits are used to distinguish three states of non-lighting "00", flicker "01", and lighting "10".
Here, the lighting is a state of an arrival forecast, and the flicker is a state of blinking of a lantern at the time of landing. Therefore,
If this value changes from “00” → “10” → “01” → “00”, the forecast lantern blinks and eventually becomes a landing flicker, and it can be recognized that the lantern has been turned off by the arrival of the car. Transmission formats for transmitting the elevator information described above from the group management control device 1 of FIG. 1 to the operation monitoring device 6 are shown in FIGS.

FIG. 5A shows the transmission format of a hall call, where the first byte is a code indicating the type of information, and is "01 (H)" in the case of a hall call. By making this value different for each piece of information, information to be transmitted can be specified. The second byte is the floor data 1 and, as shown in detail in FIG. These bit configurations are the same as those in the direction and car position in FIG.

The third byte is set / reset (= S /
R), as shown in FIG. 5C, when the most significant bit is “1”, it is set (= indicating that the hall call is lit), and when it is “0”, it is reset (= hole). Indicates that the call is turned off).

Therefore, as hall call information, for example,
When transmission data such as “01, 43, 80” is given, this indicates that “UP and hall call are lit on the third floor”.

FIG. 6A shows a transmission format of a car call, and the code of the first byte is "02 (H)".
Floor data 2 in the second byte indicates the floor where the car call occurred, as shown in FIG.
It is represented by the binary value shown in (b). In the case of this car call, since there is no direction unlike the hall call, only the floor display is performed, and there is no bit in the direction which was the hall call. The third byte is S indicating occurrence and erasure of a car call.
/ R and a car designation indicating which car the car call belongs to. As shown in FIG. 6 (c), the designation of the machine number is made up of No. in the lower two bits. 1 to No. 3 represents each unit.

FIG. 7A shows a transmission format indicating a car position, a direction, and a door state (door direction). The code is identified by "03 (H)". As shown in FIG. 7B, the car state of the second byte of this transmission format indicates the direction and the door state by two bits each, and the remaining four bits indicate the car position. These bit configurations are the same as those in FIGS. 4B to 4D.

In the third byte of this transmission format,
A machine designation indicating which machine the state is for is provided. Since the state of the car is transmitted as it is when there is a change, no bit for S / R as in the case of a car call is prepared.

Therefore, in this transmission format, data that is, for example, "03, B4, 02" indicates that "No. 2 is in the DOWN direction on the fourth floor and the door is fully open".

The load code in FIG. 8 is "04 (H)", the load in the second byte is the same as that in FIG. 4 (e), and the third byte is designated by the machine. FIG. 9 is a format showing the state of the lantern, and the code in FIG. 5A is "05 (H)".
The lantern state of the second byte in FIG.
As in (f), the bit configuration of the lantern lighting state and the position and direction in which the lantern is operating, and the third byte is the designation of the car.

FIG. 10 shows a record format when the operation monitor 6 stores various elevator information transmitted in the formats shown in FIGS. The data of various types of elevator information are all composed of 3 bytes, and in the record format of FIG. 10, these 3 bytes are respectively CODE, DATA1, and DATA.
It is represented by the symbol name 2. When recording the data received by the operation monitoring device 6, the time at that time (a relative time from the start of data collection displayed in seconds) is added to the received data to form one record. It is to be recorded, and the time at that time is indicated by the name TIME in FIG. This TIME is WO
It is RD type 2-byte data.

Accordingly, one record is composed of 5 bytes, and these records are sequentially recorded in the order of occurrence of the event. That is, if the occurrence time REC (0) of the first record and TIME are “0”, this indicates that the data occurred 0 seconds after the start of the measurement, and the time REC of the second record
(1), TIME is “5”, which is 0 after the start of measurement.
Indicates that the data occurred after a second.
The data after 6, 8, and 8 seconds are shown. Elevator operation monitoring device 6 configured as described above
Will be described with reference to the flowcharts of FIGS.

FIG. 12 is a flowchart of the operation in the group management control device 1. When the operation is started, first, the RAM (Rand) is started.
om Access Memory), and executes an initialization routine such as initial clearing of various data, various flags, and initial setting of a table (step S1, hereinafter referred to as S1).

Next, FIG.
The transmission control routine for exchanging the various types of elevator information (direction, car position, door state, etc.) shown in (2) is executed (S2), and the routine proceeds to the group management control routine (S3).

In this group management control routine, the input / output control of the hall call and the hall call
For group management operations such as allocation control for determining the optimal unit based on the state of each unit input in the transmission control routine of S2, and distributed standby control for arranging elevators in advance on appropriate floors when closing. Perform all necessary controls.

Next, in the hole state table HCT of FIG. 2 and the car state table CCT of FIG. 3 inputted in the transmission control routine of S2 and the group management control routine of S3, the newly read data and the previously read data are stored. The data is compared with the data (S4), and it is checked whether or not there is changed data (S5). Here, if there is changed data, the data is shaped into the transmission format shown in FIGS. 5 to 9 and output to the operation monitor device 6 (S6). On the other hand, if there is no changed data in S5, the flow directly goes to the point B, and the flow from the transmission control routine is repeated again.

As described above, the group management control device 1 constantly monitors changes in the state of various types of elevator information. If a change occurs in the state, the information can be transmitted to the operation monitoring device 6 immediately.

The elevator information transmitted from the group management control device 1 in this manner is sequentially received in the operation monitoring device 6 and is recorded in the data recording device 8 in the format shown in FIG.
It is stored in.

FIGS. 13 and 14 are flowcharts showing the operation of reproducing the operation state of the elevator on the display device 9 in the operation monitoring device 6 from the data at the time of traffic measurement collected and recorded as described above. A specific description will be given of a case where a phenomenon in which the duration of a hall call exceeds a predetermined value (hereinafter, referred to as a long waiting phenomenon) is treated as a failure phenomenon.

FIG. 13 shows a main routine of the operation monitoring device 6.
Initialization processing such as initial clearing and initial setting of various kinds of data is executed (S7), and then a fixed screen is set for the display device 9 (S8). Here, the fixed screen refers to a fixed screen such as a floor display, a hall call display, and a display of car information.

Next, according to the format of the defect record record shown in FIG. 11 and the flowchart shown in FIG. 15, the defect recording means for selecting and recording the defect phenomenon is executed with the long wait phenomenon as the defect phenomenon. In the present embodiment, the set and reset states of hall calls are extracted for each floor and direction based on the elevator information shown in FIG. 10 (S25 to S30),
By calculating the difference between the reset time and the set time, the duration of the hall call is obtained (S31). It is determined whether the duration of the hall call has exceeded a predetermined value (S3).
2) If the duration of the hall call exceeds a predetermined value, the monitor start time and the end time are set in the trouble recording table RRCA shown in FIG. 11 as a long wait phenomenon. In this embodiment, each time data is set from the hall call occurrence time to the erase time (S3).
3).

Next, in the record shown in FIG. 10, the index I indicating the number of the record, the value of the index COUNT used to detect the occurrence time of each record, and the The value of the index J indicating whether the record is a record is cleared to 0 (S10).

With the above, the initialization process is completed, and the process is shifted to the process of always executing the process. Based on the defect record shown in FIG. 11, the index COUNT for selecting the J-th (J = 0) data of the record in the long wait mode is set to the start time, and the record shown in FIG.
An event corresponding to a time after the time T is selected, and an index I is set. Here, the setting of the index of COUNT, I, which is the display pointer related to the J-th long wait phenomenon, is completed.

Next, a timer interrupt interval is set (S17). Here, it is assumed that the timer interrupt is activated, for example, every one second. Furthermore, in this timer interrupt interval setting routine, unless the interrupt interval is changed, resetting is not performed many times when the interval is the same, and resetting is performed only when the interval is changed.

Thereafter, in the image processing routine (S1
8) The VRAM (Video) of the data recording device 8 set in an interrupt processing routine as described later in detail.
The information on the RAM (RAM) is displayed on the display device 9.

The index COUNT is TIME2 indicating the end time of the long-waiting defect record RICA (J).
Is determined (S15), and the index CO
When the display of the J-th defect has been completed when the UNT has exceeded TIME2, the index J is incremented (S16), and the display pointer and the COUNT are set in the time zone relating to the (J + 1) -th defect record.
, And sequentially select and display only the time zones in which the trouble phenomenon has occurred.

FIG. 14 is a flowchart of a timer interrupt started at the start interval set in the timer interrupt interval setting routine of S17 in FIG. 13. According to the I and COUNT indices set in the main routine of FIG. The occurrence time REC (I) of the I-th record, T
It is determined whether the IME matches the value of COUNT (S
20) The matching data is stored in the VRAM corresponding to a predetermined position on the screen (S21). Therefore, information can be displayed on the display device 9 in the moving image mode at a time corresponding to COUNT.

Since the start interval of the timer interrupt is set to 1 second, the minimum unit of the time at the time of data collection and recording (= 1)
Second), and the execution speed of the reproduction screen matches the actual data collection time.
If it is 5 seconds, the reproduction speed will be twice the real time, and if the start interval is 2 seconds, the reproduction speed will be の of the real time. Therefore, the interrupt interval setting routine (S1) in FIG.
In 7), if this interval can be freely set by input from a keyboard of a laptop computer or the like used as the operation monitoring device 6,
The speed can be freely changed again.

Next, with reference to FIGS. 16 to 22, a description will be given of a failure phenomenon other than a long wait. In the main routine of FIG. 13, each defect phenomenon can be displayed in the same manner by replacing the defect record table RICA of FIG. 11 during the initialization process with RECB to RECE.

FIG. 16 and FIG. 17 show a process of searching for a reservation change as a defect phenomenon. The information table of FIG. 10 is searched for a lantern state, and the time at which the lantern is lit is used as a calling time table for each direction and lantern position. (S35 to S39), and when the assignment table matches the car number when the lantern is turned off (S48), the lantern is turned off without blinking. Has changed. At this timing, a flag is set in the reservation change table (S49), and the machine whose allocation has been changed enters the lantern blinking mode (S41), and upon responding, the value of the call time table is stored in the reservation change trouble recording table RECB of FIG. As the start time TIME1, the time at which the assignment change machine responded is set as the end time.

As a specific display period, when the lantern is lit, it is almost the same as the time at which the call occurred, and the assigned car responds, and the time at which the lantern blinks is synchronized with the time at which the call was erased. TIME1-RECB ・ T
In the period of IME2, the time from when a call is generated and erased is set for a hall call whose reservation has been changed. Therefore, in the display main routine of FIG. 13, by referring to the RECB table instead of the RECA, it is possible to extract and display only the trouble in which the reservation change has occurred in accordance with the RECB table information as in the case of the long wait processing.

FIG. 18 shows a search process relating to a state in which an elevator other than the elevator reserved as a malfunction phenomenon arrives first at the target floor (hereinafter referred to as car call first arrival). The timing at which a hall call is generated and assigned according to the flowchart of FIG. 18 is set as a start time, and the car deletes the hall call, blinks the lantern, and sets the response time as an end time. Store the data. At this time, using the car call first arrival table, only the hall call in which the car call first arrival phenomenon has occurred is selected and extracted. The subsequent display is the same as in FIGS.

FIG. 19 and FIG.
This is a search process relating to a state in which hall calls in the up and down directions on the same floor are assigned to one elevator (hereinafter referred to as two-way reservation). According to the flow charts of FIGS. 19 and 20, only calls in the two-way reservation mode are extracted, and the time from the occurrence time of the hall call issued first up and down to the time when the response is later erased is set as the start and end times. 1
Data is stored in the first defect phenomenon table RECD. Hereinafter, the display is the same as in FIGS. 16 and 17.

FIGS. 16 and 17 show a state in which a call on the same floor is allocated to an elevator departing from a predetermined floor within a predetermined time as a trouble phenomenon (hereinafter referred to as a back call).
This is a search process.

According to the flowcharts of FIGS. 21 and 22,
Only the mode of the back call is extracted, and the process from the generation of the call to the erasure is started, and as the end time, the failure phenomenon table
Data is stored in CE. Hereinafter, the display is the same as in FIGS. 16 and 17.

According to the above-described embodiment, with respect to data collected for a long period of time, only a defect phenomenon portion can be selected and investigated in a short time, so that a quick response to the defect phenomenon is possible. In addition, when a building management company operates this system, it is possible to easily investigate the situation of a claim from an elevator user who is an end user without having to ask an elevator maintenance company or a manufacturer expert. When a response is required, the situation can be accurately communicated to the elevator manufacturer.

In this embodiment, the operation state before and after the failure phenomenon is from when the hall call is generated until the hall call is erased. It is clear that can be treated similarly.

Further, in the present embodiment, when a moving image is reproduced on the display, the display is performed according to the mode of the trouble phenomenon. However, the display is performed through all modes, and the trouble is displayed when the trouble phenomenon occurs. The mode of the phenomenon may be displayed on the screen. Further, the malfunction phenomenon may be selected and displayed only for a specific phenomenon by a user operation from the keyboard.

Further, the present system may be incorporated in an elevator monitoring panel, data may be constantly input to the operation monitoring device and operated, and the display may be performed by a keyboard operation of a building management user.

[0057]

As described above, according to the present invention, the operation status of the elevator during the measurement period has high visibility,
Moreover, it is possible to provide an elevator operation monitoring device capable of efficiently conducting an investigation without the intervention of an elevator expert.
