Description

  The present invention relates to an elevator operation state monitoring apparatus and an elevator operation state monitoring method for displaying and monitoring an elevator operation state at a predetermined location.

  An elevator operation status monitoring device (hereinafter referred to as an “elevator operation status monitoring device”) acquires operation data representing the operation status of a car from the elevator control device, and determines the elevator operation status based on the acquired operation data. It is displayed on the display device at predetermined time intervals. The operation status monitoring device acquires operation data via a telephone line, an Internet line, or the like. The display device can display not only the floor position of the car (hereinafter referred to as “car position”) but also a flat display, an elevation display, and the like. The operating status can be monitored in real time on an easy-to-see screen.

  However, when the driving speed of the car (hereinafter referred to as “car speed”) becomes high, there is a problem that a phenomenon called car jump occurs in which the displayed car positions are discontinuous. For example, in an elevator moving at 1080 m / min, the car is more than the time required to transfer the operation data from the elevator control device to the operation status monitoring device and display the operation data acquired by the operation status monitoring device on the display device. It is conceivable that the time for the position to move becomes faster. For this reason, the display does not catch up, and a car jump such as “100 floor” → “103 floor” → “106 floor” occurs on the display device.

  In order to prevent such a car jump caused by an increase in the car speed, a technique relating to the estimation complementation of the car position has been proposed. For example, in Patent Document 1, when the car is traveling in a section where the car can travel at high speed, the car position is estimated and displayed using a driving pattern created in advance, and the section where the car can travel at low speed is displayed. There is described an elevator operation state monitoring device that displays a car position based on data received from an elevator control device when traveling. Further, in Patent Document 2, the car position is obtained by interpolating the car position by dividing the difference of the car position received at a predetermined time interval from the elevator control device at the time interval for updating the display. Is described. Furthermore, Patent Document 3 includes a switching controller that can selectively extract the latest stored data from a storage device that stores data received from the elevator control device, and displays the latest data when the screen is switched. An elevator operating condition monitoring device is described.

Embodiment 1 FIG.
The elevator operation state monitoring apparatus according to Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of an elevator operation status monitoring device 1, an elevator control device 2, and a display device 9 according to Embodiment 1 of the present invention. As shown in FIG. 1, the elevator operation status monitoring device 1 is connected to the elevator control device 2 and the display device 9, acquires operation data from the elevator control device 2, and displays the display floor in a predetermined format. To display. Here, the operation data is data representing the operation state of the car. The display floor is a car position to be displayed on the display device 9, and the car position is represented by the number of floors such as the first floor and the second floor.

  The elevator operation state monitoring device 1 and the display device 9 are installed, for example, in a monitoring room. The elevator operation status monitoring apparatus 1 includes a data receiving unit 3, a data storage unit 4, a delay time calculation unit 5, a display candidate floor calculation unit 6, a display time interval calculation unit 7, and a display control unit 8. The data receiving unit 3 receives driving data representing the driving state of the car acquired by the elevator control device 2 and outputs it to the data storage unit 4. Further, the data receiving unit 3 outputs the time at which the operation data is received (hereinafter referred to as “reception time”) to the data storage unit 4.

  In addition, as a method of receiving operation data, there is a method of transmitting online via a telephone line and an Internet line by using communication software installed in the elevator control device 2. The display device 9 is a display monitor connected to a computer, for example, and can display not only the position of the car but also the traveling direction of the car and a message indicating the occurrence of an abnormality. In addition, display formats include flat display, vertical display, and list display.

  Then, operation | movement of the elevator operation condition monitoring apparatus 1 is demonstrated. FIG. 2 is a flowchart showing an example of the operation of the elevator operation status monitoring apparatus 1 according to the present embodiment. As shown in FIG. 2, in the elevator operation status monitoring apparatus 1, when the data reception unit 3 receives the operation data, the data storage unit 4 stores the received operation data (step S <b> 01), and the delay time calculation unit 5. However, the delay time from when the operation data is acquired by the elevator control device 2 until the operation data is accumulated is calculated (step S02), and the display candidate floor calculation unit 6 calculates the accumulated operation data and the delay time. The display candidate floor is calculated based on the display candidate time (step S03), the display time interval calculation unit 7 calculates the display time interval based on the accumulated operation data (step S04), and the display control unit 8 determines the display candidate floor and the display candidate floor. The updating of the display floor is controlled based on the current display floor and the display time interval (step S05).

  The data receiving unit 3 receives operation data at any time and sets a data reception flag to 1 when new operation data is received. The data reception flag is a flag indicating that the operation data is newly received. Here, the display candidate floor is a candidate for the updated display floor, and the car position at the time of updating the display floor is estimated. The display time interval is a time interval for updating the display floor.

  Next, details of the operation of each step shown in FIG. 2 will be described. First, step S01 will be described. The data accumulating unit 4 accumulates the operation data input from the data receiving unit 3 in association with the reception time, and associates the operation data accumulation time (hereinafter referred to as “accumulation time”) with the operation data. accumulate.

  FIG. 3 is a diagram illustrating an example of operation data stored in the data storage unit 4 in the elevator operation state monitoring apparatus 1 according to the present embodiment. As shown in FIG. 3, the operation data stored in the data storage unit 4 includes the time when the elevator control device 2 acquires the operation data (hereinafter referred to as “acquisition time”) and the operation state of the car at the acquisition time. Including. In addition, the car operation status includes the car position, the advance floor, the car direction indicating the direction of travel of the car, the car call floor registered by the destination floor button operation in the car, and the hall call registered by the call button operation at the hall. It includes a floor, a progress state indicating whether the vehicle is in operation, a door state indicating a door open / close state, an abnormal state indicating an elevator abnormality, and the like.

  Here, the advance floor is a position where the car is actually stopped when the car is normally stopped at the time when the operation data is acquired. The car position at the time of operation data acquisition (hereinafter referred to as “acquired car position”). Is a position moved in the traveling direction by a distance (hereinafter referred to as “deceleration stop distance”) required until the car is stopped when the car is normally stopped. Here, the normal stop means a stop operation during normal operation. In the advance floor, when the car call floor set by the destination floor button operation in the car or the hall call floor set by the call button operation at the hall is set, the elevator stops at that call floor It is used to determine whether it can be done.

  The advance floor is a floor that has always advanced in the moving direction from the received acquisition car position, and the acquisition car position does not exceed the advance floor. Further, when the elevator is accelerating, the difference between the acquired car position and the advance floor is large, and when the elevator is decelerating, the difference between the acquired car position and the advanced floor is small. The deceleration stop distance is information that depends on the operation speed of the car. The acquired car position, the advance floor, and the deceleration stop distance are represented by the number of floors such as the first floor and the second floor.

  Next, the operation of the delay time calculation unit 5 that is step S02 of FIG. 2 will be described. From the time when the elevator control device 2 acquires the operation data to the time when the data storage unit 4 stores the operation data, internal processing such as the processing time of the above communication software, the transmission time of the operation data, and the storage of the operation data is performed. Time required is required. Therefore, a delay time occurs from when the operation data is acquired by the elevator control device 2 until the data storage unit 4 stores the operation data. In addition, this delay time may fluctuate due to a waiting time for software processing. The delay time calculation unit 5 calculates a delay time from when the operation data is acquired until it is accumulated, using the acquisition time included in the operation data, the reception time accumulated in association with the operation data, and the accumulation time. To do.

  FIG. 4 is a flowchart showing an example of the operation of the delay time calculation unit 5 in the elevator operation status monitoring apparatus 1 according to the present embodiment, and details step S02 of FIG. In the operation example shown in FIG. 4, the delay time calculation unit 5 calculates the transfer time from the difference from the operation data acquisition time to the reception time (step S <b> 21), and takes the internal processing from the difference from the reception time to the accumulation time. An internal processing time is calculated (step S22), and a delay time is calculated from the sum of the transfer time and the internal processing time (step S23). The delay time calculation unit 5 stores the calculated delay time in association with the operation data in the data storage unit 4 and outputs it to the display candidate floor calculation unit 6. The transfer time calculated in step S21 means a delay time from when the operation data is acquired until it is received by the data receiving unit 3.

  In the elevator operation status monitoring apparatus 1 according to the present embodiment, the transfer time and the internal processing time are respectively obtained and the delay time is calculated as the sum of the transfer time and the internal processing time. However, the present invention is not limited to this configuration. It can also be configured. For example, the delay time calculation unit 5 may be configured to directly calculate the delay time from the difference between the acquisition time and the accumulation time. In this case, the transfer time and the internal processing time cannot be individually known, but the configuration can be simplified.

  Next, the operation of the display candidate floor calculation unit 6 which is step S03 in FIG. 2 will be described. FIG. 5 is a flowchart showing an example of the operation of the display candidate floor calculation unit 6 in the elevator operation status monitoring apparatus 1 according to the present embodiment, and details step S03 of FIG. As shown in FIG. 5, the display candidate floor calculation unit 6 calculates a difference from the acquisition car position and the advance floor of the operation data acquired from the data storage unit 4 (step S31), and the calculated difference value and the operation data Based on the delay time associated with, similar data that is most similar to the newly received driving data is extracted from the accumulated past driving data (step S32), and the extracted similar data is used. A display candidate floor is calculated (step S33). The difference between the acquired car position and the advance floor calculated in step S31 (hereinafter referred to as “car position difference”) is equivalent to the deceleration stop distance.

  Next, extraction of similar data in step S32 shown in FIG. 5 will be described. As described above, similar data is extracted based on the car position difference and the delay time. FIG. 6 is a diagram for explaining the car position difference α and the delay time β in the elevator operation status monitoring apparatus 1 according to the present embodiment. It is the figure shown with the advance floor. For convenience, an acquisition ID field is added, and acquisition IDs are assigned in the order in which operation data is acquired. In FIG. 6, the car position difference α is represented by the number of floors such as the first floor and the second floor as in the case of the acquired car position and the advance floor. The delay time β is expressed in milliseconds.

  The display candidate floor calculation unit 6 extracts similar data most similar to the newly received operation data from the past operation data based on the car position difference α and the delay time β. As an extraction method, for example, normalization is performed for each of the car position difference α and the delay time β, and the sum of the normalized car position difference α ′ and the delay time β ′ is the highest in the newly received operation data. There is a method in which near past operation data is used as similar data. Assuming that the maximum value of the car position difference α in the past operation data is maxα and the minimum value is minα, the normalized car position difference α ′ is obtained by the equation (1). Similarly, the delay time β ′ after normalization is also obtained by Expression (1) using the maximum value maxβ and the minimum value minβ of the delay time β in the past operation data. Note that α ′ = 0 when maxα = minα, and β ′ = 0 when maxβ = minβ.

  When calculating the sum of the normalized car position difference α ′ and the delay time β ′, weighted addition is performed by applying a coefficient to the normalized car position difference α ′ or the normalized delay time β ′. You can also. By configuring in this way, it is possible to extract similar data focusing on either the car position difference or the delay time. Here, the extraction of similar data will be described using FIG. 6 as an example. The most similar operation data to the newly received operation data of acquisition ID3 is the operation of acquisition ID3 among the operation data of acquisition ID1 and ID2. This is the operation data of acquisition ID 1 that has the same value as the data and the delay time β and the closest car position difference α. Therefore, the similar data with respect to the operation data of acquisition ID3 becomes the operation data of acquisition ID1.

  In order to extract similar data, at least the car position difference α and the delay time β are used, but other operation data stored in the data storage unit 4 may be used. Further, when there are a plurality of similar data in the past, the similar data may be determined uniquely from among them, or the similar data may be calculated using an intermediate value.

  Next, the calculation of the display candidate floor in step S33 shown in FIG. 5 will be described. FIG. 7 is a diagram for explaining a display candidate floor calculation method in the elevator operation status monitoring apparatus 1 of the present embodiment, and is a diagram illustrating an example of a display candidate floor calculation method using similar data. In FIG. 7, class α is a car position difference in similar data, and class β is a delay time in similar data. In FIG. 7, α is a car position difference in newly received operation data, and β is a delay time in newly received operation data. In FIG. 7, class A is the difference between the acquired car position in the similar data and the acquired car position in the operation data acquired next to the similar data. The display candidate floor calculation unit 6 determines a range (hereinafter referred to as a “candidate range”) that is a candidate for a display candidate floor using the decision tree shown in FIG.

  For example, in the case of class α> α and class β ≧ β, the candidate range of the display candidate floor is the floor from the acquisition car position to (acquisition car position + class A), and is displayed by taking an average, for example, The candidate floor is calculated. By taking the average of the candidate ranges, the floor at the substantially center of the candidate ranges becomes the display candidate floor. Note that (acquired car position + class A) represents a car position obtained by adding a distance of class A in the traveling direction of the car to the acquired car position. When class α> α and class β <β, the candidate range of the display candidate floor is the floor from the acquisition car position to the advance floor. When the class α = α and the class β> β, the candidate range of the display candidate floor is the floor from the acquisition car position to (acquisition car position + class A). In the case of class α = α and class β = β, the candidate range of the display candidate floor is only the floor of (acquired car position + class A). When class α = α and class β <β, the candidate range of the display candidate floor is the floor from (acquired car position + class A) to the advanced floor. In the case of class α <α and class β> β, the candidate range of the display candidate floor is the floor from the acquisition car position to the advance floor. When the class α <α and the class β ≦ β, the candidate range of the display candidate floor is the floor from (acquired car position + class A) to the advanced floor.

  The display candidate floor calculation unit 6 compares the car position difference α and the delay time β with similar data, and determines a candidate range using the decision tree shown in FIG. Here, the car position difference has a characteristic that depends on the driving speed of the car. Therefore, the display candidate floor calculation unit 6 determines the candidate range by comparing the driving speed and the delay time of the car with the similar data by the decision tree shown in FIG.

  The speed of the car and the delay time affect how far the car travels during the delay time. The faster the car is running, the greater the travel distance of the car during the delay time. Also, the longer the delay time, the greater the travel distance of the car during the delay time. From the above, the display candidate floor calculation unit 6 estimates the moving distance of the car during the delay time by comparing the driving speed and the delay time of the car with the past driving data, and updates the display floor update time. The candidate range is determined by estimating the car position.

  Further, the time interval for acquiring the operation data is usually set so that the class A is smaller than the deceleration stop distance. Therefore, compared with (acquired car position + class A), the advance floor is a position advanced in the traveling direction of the car. Based on the above, the decision tree shown in FIG. 7 will be further described. FIG. 8 is a diagram for explaining a decision tree used in the display candidate floor calculation unit 6 in the elevator operation status monitoring apparatus 1 of the present embodiment, and is determined for each condition of the decision tree shown in FIG. The candidate range is described. In FIG. 8, a classification number is assigned to each determined candidate range.

  Class 1 is a case where the driving speed and the delay time of the car are both equivalent to similar data. In this case, it is considered that the car is operating substantially the same as when acquiring similar data. Under this condition, the candidate range of the display candidate floor is only the floor of (acquired car position + class A) from the operation results at the time of acquiring similar data. Next, category 2 is a case where the driving speed and the delay time of the car are both equal to or less than those of similar data, except for category 1. In this case, it is considered that the moving distance of the car during the delay time is shorter than that at the time of acquiring similar data. Under this condition, the candidate range of the display candidate floor is the floor from the acquired car position to (acquired car position + class A).

  Next, classification 3 is a case where only one of the operation speed and the delay time of the car is larger than the similar data. In this case, the moving distance of the car during the delay time may be large or small compared with the time of acquiring similar data, but the moving distance of the car is more likely to be larger than that in the case of classification 2. . Under this condition, the display candidate floor candidate range is the floor from the acquisition car position to the advanced floor. By utilizing the advance floor, when the elevator control device 2 stops the car, it is possible to suppress the problem that the display floor precedes the car position at the time of stop, or the display floor is greatly different from the actual car position. There is an effect of suppressing the detachment.

  Finally, category 4 is a case where the driving speed and the delay time of the car are both equal to or greater than those of similar data, except for category 1. In this case, it is considered that the moving distance of the car during the delay time is larger than when similar data is acquired. Under this condition, the candidate range of the display candidate floor is a floor from (acquired car position + class A) to the advanced floor.

  The decision tree shown in FIG. 7 has been described above. The decision tree shown in FIG. 7 is particularly effective when the time interval for acquiring operation data is close to the delay time, and the possibility that the candidate range includes the actual car position after the delay time is further increased. The display candidate floor calculation unit 6 uses the decision tree as shown in FIG. 7 to determine the candidate range of the display candidate floor, so that the amount of calculation can be reduced and the processing speed can be increased. As described above, the display candidate floor calculation unit 6 calculates the display candidate floor by, for example, taking an average from the candidate range of the display candidate floor.

  Next, the operation of the display time interval calculation unit 7 which is step S04 in FIG. 2 will be described. FIG. 9 is a flowchart showing the operation of the display time interval calculation unit 7 in the elevator operation status monitoring apparatus 1 according to the present embodiment, and details step S04 of FIG.

  As shown in FIG. 9, the display time interval calculation unit 7 first extracts from the data storage unit 4 the newly received operation data and the acquisition car position and acquisition time of the operation data received in the past (step S41). ). Next, the display time interval calculation unit 7 calculates the car speed between the acquisition times of the operation data using the extracted acquisition car position and the acquisition time (step S42). Next, the display time interval calculation unit 7 receives a new reception based on the newly received operation data, the acquired car position of the operation data received in the past, and the tendency of the car speed between the operation data acquisition times. The car speed between the acquisition times of the operation data received next and the operation data received next is estimated (step S43). Finally, the display time interval calculation unit 7 calculates the display time interval based on the estimated car speed (step S44).

  The operation of the display time interval calculation unit 7 will be described in more detail. First, extraction of the car position and the acquisition time in step S41 of FIG. 9 will be described. The display time interval calculation unit 7 extracts the acquisition car position and acquisition time of the operation data newly received and newly stored in the data storage unit 4, and the acquisition car position and acquisition time of the operation data accumulated in the past. To do. In addition, as the operation data accumulated in the past, the operation data accumulated last time can be extracted. Moreover, you may extract not only the operation data accumulated last time but also the acquisition car position and the acquisition time of a plurality of operation data accumulated in the past, such as the operation data accumulated last time and the last time.

Next, the calculation of the car speed in step S42 in FIG. 9 will be described. The height of the acquisition car position of newly received and accumulated operation data is Floor _i , the acquisition time is t _i , the height of the acquisition car position of the previously accumulated operation data is Floor _i−1 , and the acquisition time is t _{Assuming that i−1} , the car speed v _i between the acquisition time t _i and the acquisition time t _i−1 is obtained by Expression (2). If the unit of the height of the acquisition car position is m and the unit of the acquisition time is minutes, the unit of the calculated car speed is m / min. In step S41, when extracting the acquired car position and acquisition time of a plurality of operating data stored in the past, it can also determine the car speed v _i using the curve approximation instead of formula (2) . As the calculated car speed v _i , a predetermined number in the past is stored and used for estimating the car speed in the next step.

Next, the estimation of the car speed in step S43 in FIG. 9 will be described. FIG. 10 is a graph showing an example of the car speed (v _i ) with respect to the height (Floor _i ) of the acquired car position in the elevator operation status monitoring apparatus 1 of the present embodiment. As shown in FIG. 10, by using the height of the acquired car position of the operation data accumulated in the past and the car speed between the acquisition times of the operation data calculated corresponding to the acquired car position, The car speed until data is acquired is estimated. As a car speed estimation method, a linear approximation curve, a logarithmic approximation curve, an exponential approximation curve, a polynomial approximation curve, or the like is used. By performing nonlinear curve approximation, it is possible to improve the estimation accuracy of the car speed even when the acceleration or jerk (acceleration differential) changes.

  In addition, if there is a difference of 2 floors or more between the newly acquired and accumulated car position of the accumulated operation data and the previously accumulated accumulated car position of the operation data, each time the first floor is moved The car speed may be estimated and calculated from the graph of FIG.

Next, the calculation of the display time interval in step S44 in FIG. 9 will be described. Assuming that the estimated car speed is v _{i + 1} and the height of the car per floor is 3 m, the display time interval can be obtained by Expression (3). The display time interval obtained by Equation (3) is the time required for the car to move to the first floor. If the unit of the car speed is m / min, the unit of the display time interval calculated by the equation (3) is msec. The display time interval calculation unit 7 operates as described above. When the process of step S04 in FIG. 2 is completed, the data reception flag becomes zero.

  Next, the operation of the display control unit 8 which is step S05 in FIG. 2 will be described. FIG. 11 is a flowchart showing the operation of the display control unit 8 in the elevator operation status monitoring apparatus 1 according to the present embodiment, and details step S05 in FIG. FIG. 11 shows the operation when the car is operated to rise, and when the car is operated to descend, (XY) is replaced with (Y-X) in the comparison in step S51. In step S52, (Y + 1) is replaced with (Y-1). Hereinafter, the operation of the display control unit 8 will be described with reference to FIG.

  First, the display control unit 8 compares the display candidate floor X calculated by the display candidate floor calculation unit 6 in step S51 with the current display floor Y. If (XY)> 1, the process proceeds to step S52. If (XY) = 1 or X = Y, the process proceeds to step S53, and (X−Y) ≦ In the case of -1, the process proceeds to step S54. Here, in the case of (XY)> 1, the display candidate floor X precedes the current display floor Y by two floors or more. Note that “preceding” means that the display candidate floor X or the display floor Y is traveling in the direction of travel of the car as compared with the other. When (X−Y) = 1, the display candidate floor X precedes the current display floor Y by one floor. When X = Y, the display candidate floor X is the same floor as the current display floor Y. When (X−Y) ≦ −1, the current display floor Y precedes the display candidate floor X.

  In step S52, the display control unit 8 updates the display floor Y to (Y + 1), and the process proceeds to step S55. By the process of step S52, even if the display candidate floor X is two or more floors ahead of the current display floor Y, the car jump can be suppressed. In step S53, the display control unit 8 updates the display floor Y to the display candidate floor X, and the process proceeds to step S55. When X = Y, it is not always necessary to update the display floor in step S53.

  In step S54, the display control unit 8 checks whether or not the next operation data has been received. If the data reception flag is 1, the next operation data has been received, and if the data reception flag is 0, the next operation data has not been received. If the next operation data is not received, the confirmation is continued until it is received. If the next operation data has been received, the operation of the display control unit 8 ends, and the process proceeds to step S01 in FIG. As a result of the process in step S54, while the current display floor Y is ahead of the display candidate floor X, the display floor is not updated and the current display floor Y is maintained.

  In step S55, the display control unit 8 checks whether or not the next operation data has been received. If the next operation data has not been received, the process proceeds to step S56. If the next operation data has been received, the operation of the display control unit 8 ends, and the process proceeds to step S01 in FIG. In step S56, the display control unit 8 checks whether or not the elapsed time since the display floor has been updated has reached the display time interval. The elapsed time is reset every time the display floor is updated in step S52, step S53, and step S57. If the elapsed time has reached the display time interval, the process proceeds to step S57. If the elapsed time has not reached, the process proceeds to step S55.

  In step S57, the display control unit 8 updates the display floor to a position increased by one floor from the current display floor, and the process proceeds to step S55. When the car is lowered, the display control unit 8 updates the display floor to a position that is reduced by one floor from the current display floor. Until the next operation data is received by the processing of step S55, step S56, and step S57, the display control unit 8 continues to update the display floor one floor at a time. The display floor is output from the display control unit 8 to the display device 9 and displayed on the display device 9.

  As described above, in the elevator operation state monitoring apparatus 1 according to the present embodiment, the data receiving unit 3 receives the operation data representing the operation state of the car acquired outside, and the data storage unit 4 receives the operation data. The display time interval calculation unit 7 calculates the time interval for updating the display floor, which is the position of the car displayed externally, based on the accumulated operation data, and the delay time calculation unit 5 calculates the operation data. The delay time from the acquisition to the accumulation is calculated, and the display candidate floor calculation unit 6 estimates the position of the car at the time of updating the display floor based on the accumulated operation data and the delay time. The display candidate floor that is the updated display floor candidate is calculated, and the display control unit 8 updates the display floor based on the display candidate floor, the current display floor, and the time interval for updating the display floor. Control.

  Hereinafter, effects of the elevator operation status monitoring apparatus 1 according to the present embodiment will be described. The delay time calculation unit 5 calculates the delay time, the display candidate floor calculation unit 6 calculates the display candidate floor by estimating the car position when the display floor is updated using the delay time, and the display control unit 8 However, since the display floor is updated using the display candidate floor, the difference due to the time difference between the displayed car position and the actual car position can be suppressed.

  In particular, when the delay time fluctuates, if the display floor is updated without considering the delay time, the difference between the displayed car position and the actual car position also fluctuates. Therefore, there is a possibility that the displayed car position does not change smoothly, resulting in an unnatural display. On the other hand, according to the elevator operation state monitoring apparatus 1 of the present embodiment, such unnatural display can be suppressed.

  Moreover, the display floor can be changed one floor at a time by the control of the display control unit 8, and the car jump can be suppressed. Moreover, since the elevator operation condition monitoring apparatus 1 according to the present embodiment does not utilize a driving pattern created in advance as in the prior art, it is not necessary to create and hold a large number of driving patterns. Moreover, the elevator operation condition monitoring apparatus 1 according to the present embodiment determines the candidate range of the display candidate floor using a decision tree based on the comparison result between the newly received operation data and the extracted similar data. By configuring in this way, the amount of calculation can be reduced, and the processing can be speeded up. Also, by using a decision tree, it is possible to determine an appropriate candidate range even when the operation data accumulated in the past is small and the similarity between the newly received operation data and the extracted similar data is low. There is also an effect.

  Moreover, since the elevator operation condition monitoring apparatus 1 according to the present embodiment uses the advance floor when determining the candidate range, when the elevator control apparatus 2 stops the car, the elevator operation status monitoring apparatus 1 displays the car from the car position at the time of stop. There are also the effects of suppressing inconvenience that the floor precedes, and suppressing the display floor from significantly deviating from the actual car position. In addition, the elevator operation condition monitoring apparatus 1 of the present embodiment is particularly effective when the processing time from when the operation data is accumulated until the display floor is updated is short.

Embodiment 2. FIG.
Next, an elevator operation state monitoring apparatus according to Embodiment 2 of the present invention will be described with reference to the drawings. FIG. 12 is a diagram showing the configuration of the elevator operation status monitoring device 1A, the elevator control device 2, and the display device 9 according to Embodiment 2 of the present invention. In the elevator operation status monitoring apparatus 1 according to the first embodiment, the delay time calculation unit 5 is configured to calculate the delay time from when the operation data is acquired until it is accumulated. On the other hand, in the elevator operation status monitoring apparatus 1A of the present embodiment, the delay time calculation unit 5A is configured to calculate the delay time from when the operation data is acquired until the display floor is updated. In FIG. 12, the same components as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The elevator operation status monitoring device 1A of the present embodiment differs from the configuration of the elevator operation status monitoring device 1 of the first embodiment shown in FIG. 1 in the configurations of the delay time calculation unit 5A and the display control unit 8A. Yes. The display control unit 8A is configured to store the time when the display floor is updated (hereinafter referred to as “update time”). Specifically, the display control unit 8A basically performs the operation shown in FIG. 11 of the first embodiment, but stores the update time when the display floor is updated in step S52 or step S53, and the update time storage flag. 1 is different. The update time storage flag indicates that the update time is newly stored.

  In addition, when the update time storage flag is 1, the delay time calculation unit 5A is configured to read the update time stored in the display control unit 8A and calculate the delay time using the update time. FIG. 13 is a flowchart showing the operation of the delay time calculation unit 5A in the elevator operation status monitoring apparatus 1A according to the present embodiment, and details step S02 of FIG. 2 of the first embodiment. In the operation example shown in FIG. 13, the delay time calculation unit 5A calculates the transfer time from the difference from the operation data acquisition time to the reception time (step S21), and starts display processing from the difference from the reception time to the update time. A display processing time is calculated (step S24), and a delay time is calculated from the sum of the transfer time and the display processing time (step S25). The delay time calculation unit 5A stores the calculated delay time in association with the operation data in the data storage unit 4 and outputs it to the display candidate floor calculation unit 6.

  Here, the acquisition of the display processing time in step S24 will be described in more detail. FIG. 14 is a flowchart showing the display processing time acquisition operation in the elevator operation status monitoring apparatus 1A according to the present embodiment, and details step S24 in FIG. In step S241, the delay time calculation unit 5A checks the update time storage flag. If the update time storage flag is 1, the process proceeds to step S242. If the update time storage flag is 0, the process proceeds to step S245. In step S242, the delay time calculation unit 5A reads the update time stored in the display control unit 8A.

  In step S243, the delay time calculation unit 5A calculates the display processing time from the difference from the reception time to the update time, and sets the update time storage flag to 0. In step S244, the delay time calculation unit 5A stores the calculated display processing time. At this time, the delay time calculation unit 5A may be configured to store not only the calculated latest display processing time but also a predetermined number of past display processing times. In step S245, the delay time calculation unit 5A reads the stored display processing time. The read display processing time is used for calculating the delay time.

  The delay time calculation unit 5A operates as described above. When the update time storage flag is 0, the new display processing time is not calculated, and the already stored display processing time is used for calculating the delay time. Since the display processing time is calculated after the display floor is updated, the display processing time used for determining the display candidate floor is a past actual value. If there is a possibility that the display processing time will fluctuate greatly in a short time, in step S245, a predetermined number of past display processing times may be read and the average value thereof may be calculated. With this configuration, it is possible to suppress the influence of fluctuations in display processing time. If there is no possibility that the display processing time will fluctuate greatly in a short time, the latest display processing time may be read in step S245. With this configuration, the storage capacity and the amount of calculation can be reduced.

  Except for the operations described above, the elevator operation status monitoring apparatus 1A of the present embodiment operates in the same manner as the elevator operation status monitoring apparatus 1 of the first embodiment. If the display processing time is expected to be almost constant, the delay time can be calculated by adding the display processing time obtained in advance to the transfer time as a constant. In this case, the configuration and operation are simplified. it can.

  As described above, in the elevator operation status monitoring apparatus 1A according to the present embodiment, the data receiving unit 3 receives the operation data representing the operation state of the car acquired externally, and the data storage unit 4 is operated. The data is accumulated, the display time interval calculation unit 7 calculates the time interval for updating the display floor, which is the position of the car displayed externally, based on the accumulated operation data, and the delay time calculation unit 5A The position of the car at the time when the display candidate floor calculation unit 6 calculates the delay time from when the data is acquired until the display floor is updated, and the display candidate floor update unit 6 updates the display floor based on the accumulated operation data and the delay time. The display candidate floor that is a candidate for the updated display floor is calculated, and the display control unit 8A displays the display candidate floor based on the display candidate floor, the current display floor, and the time interval for updating the display floor. Control floor updates.

  Therefore, according to the elevator operation status monitoring apparatus 1A of the present embodiment, the same effect as the elevator operation status monitoring apparatus 1 of the first embodiment can be obtained. Furthermore, in the elevator operation status monitoring apparatus 1A according to the present embodiment, the display candidate floor is calculated using the delay time from when the operation data is acquired until the display floor is updated, so the display processing time is long. Even in this case, the difference due to the time difference between the displayed car position and the actual car position can be suppressed.

Embodiment 3 FIG.
Next, an elevator operation state monitoring apparatus according to Embodiment 3 of the present invention will be described with reference to the drawings. FIG. 15 is a diagram showing configurations of the elevator operation state monitoring device 1B, the elevator control device 2, and the display device 9 according to Embodiment 3 of the present invention. In FIG. 15, the same components as those described in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The elevator operation status monitoring device 1B of the present embodiment has the following two differences from the elevator operation status monitoring device 1 of the first embodiment. In the elevator operation status monitoring apparatus 1 according to the first embodiment, the display control unit 8 is configured to update the display floor using the display time interval calculated by the display time interval calculation unit 7 as it is. On the other hand, in the elevator operation status monitoring apparatus 1B of the present embodiment, the display control unit 8B changes the display time interval calculated by the display time interval calculation unit 7 when the difference between the display candidate floor and the display floor is large. And the display floor is updated using the changed display time interval. This is the first difference.

  As a second difference, the elevator operation state monitoring device 1B shown in FIG. It should be noted that the above two differences do not necessarily have to be applied simultaneously. First, the second difference will be described. The display floor accumulating unit 10 has a function of accumulating display floors in time series.

  FIG. 16 is a diagram illustrating an example of data stored in the display floor storage unit 10 in the elevator operation status monitoring device 1B of the present embodiment. In the example shown in FIG. 16, the data stored in the display floor storage unit 10 includes a display candidate floor and a display time interval in addition to the display floor. 16A and 16B show the display candidate floor newly calculated by the display candidate floor calculation unit 6 and the display time interval newly calculated by the display time interval calculation unit 7. FIG. The display floor storage unit 10 is configured so that the stored data can be read from the outside. By providing the display floor accumulating unit 10, it is possible to check the past history of the display floor when a problem occurs.

  Next, the first difference will be described. FIG. 17 is a flowchart showing the operation of the display control unit 8B in the elevator operation status monitoring apparatus 1B according to the present embodiment, and details step S05 of FIG. 2 of the first embodiment. Note that FIG. 17 shows the operation when the car is operated to rise, and when the car is operated to descend, (X−Y) is replaced with (Y−X) in the comparison of S51. In S52, (Y + 1) is replaced with (Y-1). The operation of the display control unit 8B shown in FIG. 17 is different from that shown in FIG. 11 of the first embodiment only in that step S58 is provided between step S51 and step S52. In FIG. 17, the same processes as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

First, in step S51, the display control unit 8B compares the display candidate floor X calculated by the display candidate floor calculation unit 6 with the current display floor Y. If (XY)> 1, the process proceeds to step S58. That is, if the display candidate floor is two or more floors ahead of the display floor, the process proceeds to step S58. In other cases, the processing is the same as in FIG. 11 of the first embodiment. In step S58, the display control unit 8B uses the display time interval t calculated by the display candidate floor X, the display floor Y, and the display time interval calculation unit 7, for example, and the display time interval after the change according to Expression (4). Find t ^' . As described above, the display control unit 8B adjusts the display time interval. In the expression (4), since (XY)> 1, the display time interval t ^′ after the change is shorter than the display time interval t.

Until the next display time interval t is calculated by the display time interval calculation unit 7, the display control unit 8B uses the changed display time interval t ^′ . Here, Expression (4) is an example. If the display time interval t ^′ after the change is shorter than the display time interval t, t ^′ obtained by Expression (4) is further multiplied by a coefficient to obtain a result after the change. It is good also as a display time interval, and you may use another type | formula. When the display time interval after the change is obtained, the process proceeds to step S52. Subsequent operations are the same as those described in the first embodiment.

  The display floor Y used in the display control unit 8B may be configured to be stored inside the display control unit 8B, or may be configured to be read from the display floor storage unit 10. In addition, although FIG. 17 shows an example in which step S52 is processed after step S58, the order of this processing may be reversed or simultaneous.

  The elevator operation state monitoring device 1B of the present embodiment operates as described above. In the elevator operation status monitoring apparatus 1 according to the first embodiment, even when the difference between the display candidate floor and the display floor is two or more floors, the occurrence of a car jump is suppressed by changing the display floor one floor at a time. Was. However, since the display time interval is not adjusted, the difference between the display candidate floor and the display floor remains large and may not be improved. Here, since the display candidate floor is the car position estimated by the display candidate floor calculation unit 6, it is desirable that the difference between the display candidate floor and the display floor is small.

  In the elevator operation status monitoring apparatus 1 according to the present embodiment, the display candidate floor is compared with the display floor, and when the display candidate floor is two or more floors ahead of the display floor, the time interval for updating the display floor is set. It is configured to be shortened, and the difference between the displayed car position and the actual car position can be further suppressed. Moreover, according to the elevator operation condition monitoring apparatus 1B of the present embodiment, the same effect as the elevator operation condition monitoring apparatus 1 of the first embodiment can be obtained.

  In the elevator operation status monitoring apparatus 1B according to the present embodiment, the configuration of the display control unit is changed and the display floor accumulation unit is added to the elevator operation status monitoring apparatus 1 according to the first embodiment. However, the configuration change of the display control unit and the addition of the display floor storage unit can also be applied to the elevator operation status monitoring apparatus 1A of the second embodiment.

Embodiment 4 FIG.
Next, an elevator operation state monitoring apparatus according to Embodiment 4 of the present invention will be described with reference to the drawings. FIG. 18 is a diagram showing the configuration of the elevator operation status monitoring device 1C, the elevator control device 2, and the display device 9 according to Embodiment 4 of the present invention.

  In the elevator operation status monitoring apparatus 1 according to the first embodiment, the display candidate floor calculation unit 6 is configured to calculate a display candidate floor using a decision tree. On the other hand, in the elevator operation status monitoring apparatus 1C of the present embodiment, the display candidate floor calculation unit 6C uses the car speed and the delay time estimated by the display time interval calculation unit 7C to update the display floor. The display candidate floor is calculated by estimating the car position. Accordingly, the display time interval calculation unit 7C is configured to output the estimated car speed to the display candidate floor calculation unit 6C.

Similar to the display time interval calculation unit 7 of the first embodiment, the display time interval calculation unit 7C estimates the car speed v _{i + 1} from when new operation data is acquired until the next operation data is acquired. The display time interval calculation unit 7C outputs the estimated car speed v _{i + 1} to the display candidate floor calculation unit 6C. The other operation of the display time interval calculation unit 7C is the same as that of the display time interval calculation unit 7 of the first embodiment. The display candidate floor calculation unit 6C calculates the display candidate floor X according to the equation (5) using the estimated car speed v _{i + 1} . In equation (5), Z is the position of the car from which the newly received operation data is acquired, and td is the delay time calculated by the delay time calculation unit 5. In addition, the addition in Formula (5) means that distance is added toward the advancing direction of a cage | basket | car. Therefore, equation (5) means that the movement distance of the car during the estimated delay time is added toward the traveling direction of the car with respect to the acquired car position. The travel distance is calculated in terms of floor number.

  Moreover, FIG. 19 is a flowchart which shows an example of operation | movement of 1 C of elevator operation condition monitoring apparatuses of this Embodiment. The operation of the elevator operation status monitoring device 1C shown in FIG. 19 differs from the operation shown in FIG. 2 of the first embodiment only in that the processing order of step S04 and step S03 is switched. The elevator operation status monitoring device 1C shown in FIG. 19 performs the process of step S03 after the process of step S04 in order to use the car speed estimated in step S04 when calculating the display candidate floor in step S03. It is configured.

  The elevator operation status monitoring device 1C of the present embodiment operates as described above. According to the elevator operation status monitoring apparatus 1C of the present embodiment, the car position at the time of updating the display floor is estimated based on the operation data and the delay time without using the decision tree, and the display candidate floor is calculated. Therefore, the difference due to the time difference between the displayed car position and the actual car position can be suppressed.

  The elevator operation status monitoring device 1C of the present embodiment has been described as a configuration in which the operations of the display candidate floor calculation unit and the display time interval calculation unit are changed with respect to the elevator operation status monitoring device 1 of the first embodiment. However, the change in the operations of the display candidate floor calculation unit and the display time interval calculation unit can also be applied to the elevator operation status monitoring device 1A of the second embodiment and the elevator operation status monitoring device 1B of the third embodiment. .
