A control unit for updating the car position data stored in the storage unit, and updating the car position display on the display based on the updated car position data; When the data is acquired, the car position data stored in the storage unit is compared with the acquired car position data, and it is assumed that the acquired car position data indicates the movement along the traveling direction of the car When the determination is made, the car position data stored in the storage unit is updated based on the acquired car position data, and the acquired car position data indicates the movement in the direction opposite to the traveling direction of the car. And when determining, whether car position data stored in the storage unit, updates based on whether your location data stored in the storage unit at the time of acquiring the car position data.

  Further, in order to solve the above problems, the elevator car position display method according to the present invention is a method of displaying the position of the elevator car by a moving image, and when acquiring the car position data, the car at the past time point The position data is compared with the acquired car position data, and when the acquired car position data indicates movement along the traveling direction of the car, the car position display is performed based on the acquired car position data. If the acquired car position data indicates the movement in the direction opposite to the traveling direction of the car, the car position display is updated based on the car position data at the past time.

  According to the present invention, an unnatural car position indication for elevator users is prevented such that the car position moves in the opposite direction to the traveling direction. Therefore, it is possible to provide the elevator user with kind car position information.

  Problems, configurations, and effects other than those described above will be clarified by the description of the embodiments below.

It is a functional block block diagram of a cage | basket | car position display apparatus which is one Embodiment of this invention. It is an example of a display of the present position of the car in a car position indicator. It is a flowchart which shows the display control processing operation in the control apparatus for cage position display. An example of the data processing in step S10 and S11 in FIG. 3 is shown. An example of the data processing in step S10 and S14 in FIG. 3 is shown. The modification of a cage | basket | car position indicator is shown.

  Hereinafter, embodiments of the present invention will be described based on the drawings.

  In the drawings, those with the same reference numerals indicate components having the same configuration or similar functions.

  FIG. 1 is a functional block diagram of a car position display device according to an embodiment of the present invention.

  The control device 12 for car position display is a rotary encoder provided in the motor of the hoist, that is, a motor or a rotational phase signal of a sheave driven by the motor output from the motor 1 and a position provided in the car Displayed from position detection signal output from detection device 2 and cage position data obtained based on rotation phase signal of governor pulley or governor roller output from rotary encoder provided on governor (speed governor), that is, governor encoder 3 The car position data is created and output to the car position indicator 11.

  In the car position display control device 12, each signal of the motor encoder 1, the position detection device 2 and the governor encoder 3 is received by the receiving unit 4 and the display control unit 6 performs car position data based on each received signal. And display car position data based on the acquired car position data. The display car position data created by the display control unit 6 is output through the transmission unit 5 and transmitted to the car position indicator 11.

  The car position display device 11 displays the current position of the car as a moving image according to the display car position data. A liquid crystal display or the like is applied as the car position display 11.

  In the display control unit 6, the actual car position conversion unit 8 generates car position data from the signal of the motor encoder 1 received by the reception unit 4. Further, the car position correction unit 7 corrects the car position data created by the real car position conversion unit 8 based on the signals of the position detection device 2 and the governor encoder 3. Here, the actual car position conversion unit 8 and the car position correction unit 7 may have the same function that the elevator control device (not shown) uses for operation control of the car.

  In the present embodiment, the position detection device 2 (e.g., a positive protector) detects a car passing through a detection target (e.g., a shielding plate) fixed to a plurality of predetermined positions in a hoistway in which the car travels. Output position signal. The car position correction unit 7 detects the general position of the car based on the signal of the governor encoder 3 and determines the position of the detected object through which the car passes from the detected general position. The car position correction unit 7 stores in advance the absolute position (for example, the height from the reference floor such as the lowermost floor) of the detected object in the hoistway. Therefore, the car position correction unit 7 determines the absolute position of the detected object through which the car passes, that is, the absolute position of the car, based on the signals of the position detection device 7 and the governor encoder 3. Then, the car position correction unit 7 corrects the car position data created by the real car position conversion unit 8 from the signal of the motor encoder 1 to the absolute position of the car determined by the car position correction unit 7.

  The signal output from the position detection device 2 is differentiated by changing the shape, material, etc. of the object to be detected according to the fixed position of the object to be detected in the hoistway, whereby the absolute position of the object to be detected is obtained. That is, the absolute position of the car may be determined. In this case, the governor encoder 3 may not be used.

  The car position data generated by the actual car position conversion unit 8 and the car position data corrected by the car position correction unit 7, that is, the car position data acquired by the display control unit 6 are stored in the car position storage unit 9. Based on the car position data stored in the car position storage unit 9, the display device car position conversion unit 10 creates display car position data. The generated display car position data is transmitted to the car position indicator 11 by the transmitter 5.

  When the latest car position data is acquired, the car position storage unit 9 updates the stored car position data as described later. Based on the car position data stored in the car position storage unit 9 after the data update, the display car position data created by the display device car position conversion unit 10 is updated. As a result, the current car position displayed on the car position indicator 11 is updated, so that the car position moves on the display screen.

  In the present embodiment, as described above, since the car position data created by the real car position conversion unit 8 is corrected when a plurality of objects to be detected fixed in the hoistway are detected, the correction is performed. The time interval at which the cage position data is acquired is longer than the time interval at which the cage position data created by the actual cage position conversion unit 8 is acquired without being corrected. Therefore, when the acquired latest car position data is the car position data corrected by the car position correction unit 7, the car position data stored in the car position storage unit is corrected by the car position correction unit 7. There is no car position data. Data update in the car position storage unit 9 in such a situation is as follows.

  The car position storage unit 9 compares the latest car position data (with correction) with the car position data (without correction) stored in the car position storage unit 9, and the latest car position data If it is determined that the car position change along the direction or downward direction is indicated, the car position data stored in the car position storage unit is updated to the latest car position data (with correction). When the car position storage unit 9 determines that the latest car position data indicates a car position change in the direction opposite to the traveling direction of the car, the car position storage unit 9 does not update the latest car position data (with correction). The car position data (without correction) stored in the car position storage unit 9 is copied as update data. As a result, it is possible to prevent the car position display device 11 from reversing the car position display.

  In the present embodiment, the car position storage unit 9 stores a predetermined plurality of car position data in time series. When the latest car position data is acquired, the car position data stored one time before the current time, that is, the latest car position data in the time series is updated as described above. The display device car position conversion unit 10 creates such a display car position data by averaging such a plurality of car position data (for example, calculating an arithmetic average value). As a result, the car position suddenly changes due to acceleration operation and the like, and even if the instantaneous car position data largely changes, the car position display on the car position display device 11 suddenly moves, which is unnatural to general customers The visible movement is prevented. Therefore, in the screen of the car position indicator 11, the car position indication moves smoothly.

  In the present embodiment, each unit of the car position display control device 12 including the car position data update function of the car position storage unit 9 when the arithmetic processing unit such as the microcomputer executes a predetermined computer program. Act as. Further, in the car position storage unit 9, a plurality of car position data are stored in a storage device such as a semiconductor memory.

  FIG. 2 is a display example of the current position of the car in the car position indicator. In addition, the building where the elevator is installed is 6 floors.

  As shown in FIG. 2, in the car position indicator 11, the numbers indicating the floors of the building where the car travels and the display positions of the horizontal lines are fixed, and the figures representing the cars, that is, the display positions of the rectangular patterns in the figure are the car Move on the screen according to the movement of. For example, when the car is stopped at the fourth floor (left side in FIG. 4), the rectangular pattern is between the horizontal line indicating the division between the third floor and the fourth floor and the horizontal line indicating the division between the fourth floor and the fifth floor, ie In the screen area showing the floor, it is stationary next to the number "4". In addition, when the car leaves from the fourth floor upward and travels between the fourth floor and the fifth floor (left side in FIG. 4), the rectangular pattern moves upward on the screen.

  Thus, in the present embodiment, the position of the car is displayed using a moving image. For this reason, the elevator user can intuitively grasp the current position of the car to be used in the building.

  FIG. 3 is a flowchart showing a display control processing operation in the car position display control device 12 (mainly the display control unit 6).

  First, in step S1, the car position storage unit 9 determines whether the car position data created by the actual car position conversion unit 8 is not stored in the encoder information storage table in the car position storage unit 9 for all N pieces. It is determined by If it is determined that all N pieces of data are not stored in the car position storage unit 9 (YES in step S1), the car position display is prohibited in step S2. If it is determined in step S1 that the data is not stored (NO in step S1), step S5 is executed next.

  Since step S2 is executed at the rise of the car position display device, next, in step S3, all N pieces of data in the car position storage unit 9 are initialized with the current car position data.

  Next, in step S4, the display device car position conversion unit 9 calculates the average value of all N car position data stored in the car position storage unit 9 to create display cage position data, and creates it. The current car position is displayed on the car position indicator 11 according to the display car position data. After step S4 is executed, step S5 is executed next.

  In step S5, the reception unit 4 determines whether the signal from the motor encoder 1 used to generate the latest car position data is received or not, based on the signal of the motor encoder 1, the latest car position data is It is determined whether it has been acquired. If it is determined that the latest car position data has been acquired (YES in step S5), then step S6 is executed, and it is determined that the latest car position data is not acquired (NO in step S5) The process ends.

  In step S6, the first car position data, which is the earliest car position data in time series, is deleted among all N car position data stored in the car position storage unit 9. Next, in step S7, each of the second to N-th car position data stored in the car position storage unit 9 is shifted by one point in time. As a result, the second to N-th car position data become the first to (N-1) -th car position data.

  Next, in step S8, it is determined whether the elevator is traveling. For the determination, an operation command generated by an elevator control device (not shown) is used. If it is determined that the elevator is traveling (YES in step S8), then step S9 is executed. When it is determined that the elevator is not traveling (NO in step S8), step S15 is next executed.

  In step S9, as described later, when the car position data at the time of stop is stored in the car position storage unit 9, the car position data at the time of stop is deleted.

  After the execution of step S9, in order to prevent the figure indicating the car in the car position indicator 11 from moving unnaturally in such a way that it runs counter to the direction of movement of the car, the processes after step S10 are performed. Ru.

In step S10, of the car position data stored in the car position storage unit 9, the latest car position data is closest to the time when the latest car position data is acquired (one time before the current time, It is determined whether or not the first car position data has been updated in the traveling direction of the car. For example, when indicating the height from the bottom floor cage position data to a car position, and the latest cage position data and the N-1 th cage position data and x _new and x _N-1, respectively, the Kagogaue direction If _traveling, if _{x new> x N-1,} x new is determined to have been updated in the upward _direction, if _{x new <x N-1,} x new has not been updated in the upward direction It is determined that

  When it is determined in step S10 that the latest car position data is updated in the traveling direction (YES in step S10), the latest car position data is the Nth car position data, and the car position storage unit Stored in 9 When it is determined that the latest car position data is not updated in the traveling direction (NO in step S10), that is, the car position data extracted from the signal of the motor encoder is corrected, and the latest car position data is corrected. Is determined to be updated in the direction opposite to the traveling direction, then step S14 is executed. In step S14, the car position data one point before the current time, that is, the (N-1) -th car position data is stored (copied) in the car position storage unit 9 as the N-th car position data. As described above, by using the car position data before correction as the current (N-th) car position data to be stored in the car position storage unit 9, the figure indicating the car in the car position display device 11 is in the traveling direction of the car. It is possible to prevent an unnatural movement such as going backwards.

  When it is determined that the elevator is not traveling (stopped) in the above-described step S8 (NO in step S8), next, in step S15, control information from an elevator control device (not shown), that is, the elevator It is determined whether the car position data at the time the car stopped has been acquired. If it is determined that the car position data when the elevator has stopped is acquired (YES in step S15), then step S17 is executed. When it is determined that the car position data when the elevator has stopped is not acquired (NO in step S15), next, after acquiring the car position data at the time of stop in step S16, step S17 is executed. Be done.

  In step S17, the acquired car position data at the time of stopping is stored in the car position storage unit 9 as Nth car position data.

  Here, when the elevator arrives at the destination floor after responding to the user's call, the car may vibrate although the position of the car is very small due to the user getting on and off. On the other hand, even if the car position vibrates by setting the car position data at the time of stop to the current time stored in the car position storage unit 9, ie, the Nth data, while the elevator is stopped in step S17 described above. The figure showing the car displayed on the car position indicator 11 is stationary without vibration. When the elevator starts traveling, when the step S9 is executed, the car position data at the time of stopping stored in the car position storage unit 9 is deleted. Therefore, the car position data at the time of stopping does not affect the display control during traveling.

  When one of the steps S11, S14 and S17 as described above is performed, then step S12 is performed. In step S12, the display device car position conversion unit 10 calculates the average value of the plurality of car position data stored in the car position storage unit 9, that is, N car position data, and displays the car position according to the calculated average value. Data is created.

  Next, in step S13, the data for car position display displayed by the car position indicator 11 is updated to the data for car position display created in step S12.

  Here, at the time of acceleration or deceleration of the elevator, since the car position changes rapidly, the figure showing the car in the car position indicator 11 may seem to move unnaturally, such as moving suddenly suddenly. . On the other hand, in the present embodiment, the car position display data is created based on the average value of the plurality of car position data stored in the car position storage unit 9 in step S12. The figure showing the car can be moved smoothly in.

  FIG. 4 shows an example of data processing in steps S10 and S11 in FIG. 5 shows an example of data processing in steps S10 and S14 in FIG. In FIGS. 4 and 5, the car is traveling upward.

As shown in FIG. 4, in the data areas X ₁ , X ₂ ,..., X _{N -1} and X _N in the car position storage unit 9, car position data representing car positions are stored in time series. . That is, the car position data stored in the data areas X ₁ , X ₂ ,..., X _{N -1} , X _N is car position data of the past time point in this order. During updating of the cage position data, the data area _{X 1,} X 2, · · _·, the _{X N-1, X N,} respectively, car position _{x 1, x 2, ···,} x N-1, x _The cage position data representing _N is stored. x ₁ , x ₂ ,..., x _{N -1} , x _N are time series data, and are car position data in the past in this order. The car position is the height from the lowest floor landing position to the car 50.

Currently, although recent cage position data x _new is acquired, x _new is car position or calculated in real car position conversion unit 8 is corrected by car position correcting unit 7. The car position storage unit 9 updates the car position data to be stored since x _new is obtained. At this time, the cage position storage unit _{9, x new} and compares the cage position data _{x N} before a point in time than the present _{time, x} new> because it is _{x N,} the traveling direction of the car of _{x new} is at present ( It is determined that the car position data indicates the movement of the car along the upward direction).

When updating the data, car position storage unit 9, first, remove the squirrel position data x ₁ is stored in the data area X _1, then, remains squirrel position data x _2, · · ·, x _{N- 1} and x _N are data shifted from the data areas X ₂ ,..., X _N-1 , and X _N to data areas X ₁ ,..., X _N-2 , and X _{N -1} , respectively. Moreover, the car position storage unit 9 stores the newest car position data x _new it is determined that indicates the movement of the car along the traveling direction of the car (upward) in the data area X _N.

In this manner, based on the cage position data of the updated or car position in the storage unit 9, since the car position display in the car position indicator 11 is updated, the car at the present time indicated by the latest cage position data x _new The figure representing the car moves in the direction of travel (upward).

In the present embodiment, as described above, the display of the car position is updated based on the average value (for example, arithmetic average value) of x ₂ , ..., x _{N -1} , x _N , x _new Be done. _{x 2, ···, x N-} 1, x N, x new is before the update _{x 1,} ···, against _{x N-1, x N,} x 2> x 1, ···, x _{Since N} > x _N-1 and x _N > x _new , the updated average value is larger than the average value before the update. Therefore, even if updating is performed based on the average value, the figure representing the car moves in the current direction of travel of the car (upward). Furthermore, by updating the display based on the average value, even if x _new becomes significantly larger than x _N due to a sudden acceleration of the car, the position of the figure representing the car may be rapidly changed in the display. It is prevented. That is, the movement of the figure representing the car can be smoothed.

In the data processing shown in FIG. 5 is different from the data processing shown in FIG. 4, the latest cage position data _{x new new,} less than one time before the cage position data _{x N} than the present time _(x new _<x N). That is, since the car position data created in the real car position conversion unit 8 is corrected by the car position correction unit 7, x _new is the car movement direction (upward) with respect to the car position data x _N. Indicates a car position in the reverse direction (downward direction).

In this case, when the data is updated, the car position storage unit 9 deletes x ₁ as in the data processing of FIG. 4, and the remaining car position data x ₂ ,..., X _{N -1} , x _N Shift data Moreover, the car position storage unit 9 is different from the data processing of FIG. 4, copying the cage position data x _N in the data area X _N. Thus, figure representing the car in display, the traveling direction of the car (the upward direction) in response to x _new is prevented from unnatural movements such as moving in the opposite direction.

Also in the case of the data processing shown in FIG. 5, the display of the car position is based on the average value of a plurality of time series data x ₂ , ..., x _{N -1} , x _N , x _N stored in the car position storage unit. It will be updated. _{x 2, ···, x N-} 1, x N, x N is before the update _{x 1,} ···, against _{x N-1, x N,} x 2> x 1, ···, x _{Since N} > x _N-1 and x _N = x _N , the updated average value is larger than the average value before the update. Therefore, even if updating is performed based on the average value, the figure representing the car moves in the current direction of travel of the car (upward). Furthermore, by updating the display based on the average value, the movement of the graphic representing the car can be smoothed.

  As described above, according to the present embodiment, when the acquired car position data is the corrected car position data based on the absolute position data of the car when the car position display is updated, the acquired car position data is acquired The position data is acquired when the car position data stored in the car position storage unit and created based on the rotation of the motor for driving the car changes in the traveling direction of the car. The car position is displayed based on the car position data, and the car position is displayed based on the car position data stored in the car position storage unit when the car position changes in the direction opposite to the traveling direction of the car. This prevents the elevator user from displaying an unnatural car position such that the car position moves in the opposite direction to the traveling direction. Therefore, the elevator user can easily and intuitively know the current position of the car to be used without having a sense of incongruity or reliability on the display. Therefore, it is possible to display to the elevator user the kind car position information according to his position and feeling.

  Further, according to the present embodiment, the car position display may suddenly or intermittently move by displaying the car position based on the average value of the plurality of time-series car position data stored in the car position storage unit. The position of the car moves smoothly without any movement. Thus, the elevator user can smoothly grasp the current position of the car without being caught by the movement of the displayed car.

  FIG. 6 shows a modification of the car position indicator.

  In this variant, as with the car position indicator shown in FIG. 2, the numbers and the horizontal lines indicate the floor of the building on which the car is traveling, and the car in a rectangular pattern. Furthermore, in this modification, unlike the car position display device shown in FIG. 2, in the display screen, the position of the rectangular pattern representing the car is fixed, and the numbers representing the background of the rectangular pattern, ie the floor, and the horizontal lines are up and down. Scroll to In this modification, such scroll does not reverse and moves smoothly.

  By applying the car position indicator of the present modification in the above-described embodiment, as in the case of applying the car position indicator shown in FIG. 2, providing kind car position information to elevator users The elevator user can smoothly grasp the current position of the car. Further, since the size of the car position display device can be reduced in this modification, it is suitable for a high-rise building having a large number of floors.

  The present invention is not limited to the embodiment described above, and includes various modifications. For example, the embodiments described above are described in detail to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the configurations described. In addition, it is possible to add, delete, and replace another configuration for part of the configuration of each embodiment.

  For example, the rotation of the motor may be detected sensorlessly. Further, as the absolute position data of the car, it is possible to use various sensors in one-to-one correspondence with the position in the hoistway.

  The elevator may be a so-called machine room-less elevator in which a hoisting machine or a control device is installed in the hoistway, or may be one in which the hoisting machine or the control device is installed in a machine room at the top of the hoistway.
