Embodiment 1.

BRIEF DESCRIPTION OF THE DRAWINGS It is a figure which shows the example of the elevator system in Embodiment 1. FIG. The elevator system shown in FIG. 1 includes an elevator 1 and a data center 2 . The elevator 1 and the data center 2 can communicate via a communication network 3 . The manner in which the elevator 1 and the data center 2 communicate may be any system. FIG. 2 is a diagram showing an example of a connection of devices provided in the elevator 1 .

The elevator 1 includes, for example, a car 10 and a counterweight 11 . The car 10 moves up and down the hoistway 12 . The counterweight 11 moves the hoistway 12 up and down. The car 10 and the counterweight 11 are suspended from the hoistway 12 by a main rope 13 .

The traction machine 14 includes a drive sheave 15 , an electric motor 16 , and a brake device 17 . A main rope 13 is wound around the drive sheave 15 . The electric motor 16 drives the drive sheave 15 . The electric motor 16 is controlled by a control device 18 . That is, the control device 18 controls the rotation and stop of the drive sheave 15 . The car 10 moves according to the rotation of the drive sheave 15 . If the drive sheave 15 is not rotating, the car 10 stops. An encoder (not shown) is provided on the rotating shaft of the electric motor 16 . When the electric motor 16 rotates, a rotation signal indicating the rotation direction and rotation angle is output from the encoder. The rotation signal output from the encoder is input to the control device 18 .

The brake device 17 is a device for holding the car 10 stationary. The brake device 17 is controlled by a control device 18 . In normal operation, the brake device 17 operates after the drive sheave 15 stops. When the brake device 17 operates, a force is applied to a member interlocking with the drive sheave 15 to prevent rotation of the drive sheave 15 .

The governor 19 operates the emergency stopper 20 provided in the car 10 when the descending speed of the car 10 exceeds a specific first reference speed. The governor 19 includes, for example, a speed governor rope 21 , a speed governor sheave 22 , and a tension sheave 23 . The speed control rope 21 is connected to the car 10 . The speed regulation rope 21 is wound around the speed regulation sheave 22 and the tension sheave 23 . When the car 10 moves, the speed control rope 21 moves. When the speed regulation rope 21 moves, the speed regulation sheave 22 and the tension sheave 23 rotate. An encoder may be provided on the rotation shaft of the speed control sheave 22 . In this case, a rotation signal indicating the rotation direction and rotation angle of the speed control sheave 22 is output from the encoder. The rotation signal output from the encoder is input to the control device 18 .

The safety device 24 is provided in the hoistway 12 , for example. The safety device 24 forcibly stops the car 10 when the car 10 enters the terminal floor at a speed faster than a specific second reference speed. In the example shown in FIG. 1, when the cage|basket|car 10 passes upward at a speed faster than the 2nd reference speed, the safety device 24 will operate|moves. When the safety device 24 operates, the deceleration of the electric motor 16 is forcibly started. Thereby, the drive sheave 15 stops. That is, the car 10 stops.

The battery 25 is used to disembark passengers in the car 10 to the nearest floor in the event of a power outage. For example, when a power outage occurs, electric power from the battery 25 is supplied to the control device 18 , the hoisting machine 14 , and the car 10 .

The communication device 26 communicates with the data center 2 . The communication device 26 is connected to the control device 18 . Any method may be used for the communication device 26 to communicate with the data center 2 .

1 shows an example in which a hoisting machine 14 , a control device 18 , a battery 25 , and a communication device 26 are provided in a hoistway 12 . When the elevator 1 has a machine room, the hoisting machine 14, the control device 18, the battery 25, and the communication device 26 may be provided in the machine room. A part of the traction machine 14, the control device 18, the battery 25, and the communication device 26 may be provided in the machine room.

As shown in FIG. 2 , the control device 18 includes, for example, an operation control unit 30 , a measurement unit 31 , and a temperature acquisition unit 32 . Hereinafter, also with reference to FIG. 3 and FIG. 4, the function with which the control apparatus 18 is equipped is demonstrated. 3 is a flowchart showing an operation example of the control device 18 .

In the control device 18, it is determined whether the start condition is satisfied (S101). The start condition is a condition for starting the diagnostic operation. The starting condition is set in advance. If the start condition is not satisfied, the operation control unit 30 controls the normal operation, for example. In normal operation, the operation control unit 30 answers the car 10 in turn to registered calls.

As an example, the diagnostic operation is performed regularly. For example, if it becomes 1 am on the 10th of every month, the start condition is satisfied. As another example, the diagnostic operation is performed irregularly. For example, when the communication device 26 receives a specific signal from the outside, the start condition is established. When the start condition is established, the driving control unit 30 starts a diagnostic operation ( S102 ). The diagnostic operation is performed to determine whether there is an abnormality in the equipment provided in the elevator 1 .

The operation control unit 30 causes the car 10 to perform a specific operation, for example, by using a specific device in a diagnostic operation. The measurement unit 31 measures a specific value in the diagnostic operation (S103). For example, the measurement part 31 measures the value regarding the operation|movement of the cage|basket|car 10, or the value regarding the said apparatus. The value measured by the measurement unit 31 is used in order to determine the presence or absence of an abnormality.

As an example, the operation control unit 30 causes the car 10 to perform a specific operation using the battery 25 in the diagnostic operation. For example, the driving control unit 30 causes the car 10 to perform a specific driving by electric power from the battery 25 . In the diagnostic driving, the voltage value of the battery 25 is measured by the measuring unit 31 while the specific driving is being performed. When the minimum voltage value Vmin of the battery 25 measured by the measurement part 31 is less than a reference value, abnormality is determined.

As another example, the operation control unit 30 causes the car 10 to perform a specific operation by using the brake device 17 in the diagnostic operation. For example, the operation control unit 30 moves the car 10 in a specific direction at a specific speed. The operation control unit 30 operates the brake device 17 when the car 10 is moving at the specific speed. When the brake device 17 operates, the car 10 starts decelerating, after which the car 10 stops. The measurement unit 31 measures the distance traveled by the car 10 from the time the brake device 17 operates until the car 10 stops. Hereinafter, this distance is also expressed as movement distance L1. For example, measurement of the movement distance L1 is performed based on the rotation signal from the encoder provided in the rotation shaft of the electric motor 16. As shown in FIG. When the encoder is provided on the rotation shaft of the speed control sheave 22 , the measurement of the movement distance L1 may be performed based on a rotation signal from an encoder provided on the rotation shaft of the speed control sheave 22 . When the movement distance L1 measured by the measurement part 31 exceeds a reference value, abnormality is determined.

As another example, the operation control unit 30 causes the car 10 to perform a specific operation by using the safety device 24 in the diagnostic operation. For example, the operation control unit 30 causes the car 10 to enter the terminal floor at a specific speed faster than the second reference speed. Thereby, the safety device 24 operates. The measurement part 31 measures the distance that the cage|basket|car 10 moved from the time the safety device 24 operated until the cage|basket|car 10 stopped. In the following, this distance is also referred to as a movement distance L2. For example, measurement of the movement distance L2 is performed based on the rotation signal from the encoder provided in the rotation shaft of the electric motor 16. As shown in FIG. When the encoder is provided on the rotation shaft of the speed control sheave 22 , the measurement of the movement distance L2 may be performed based on a rotation signal from an encoder provided on the rotation shaft of the speed control sheave 22 . When the movement distance L2 measured by the measurement part 31 exceeds a reference value, abnormality is determined.

When the diagnostic operation is finished (S104), the measurement value by the measurement unit 31 is transmitted to the data center 2 (S105). The measurement value transmitted to the data center 2 includes, for example, the minimum voltage value Vmin, the movement distance L1, and the movement distance L2. In addition, the elevator 1 may be equipped with the function of determining the presence or absence of abnormality, and the data center 2 may be equipped. When the elevator 1 is provided with the above-mentioned determination function, the determination of the presence or absence of an abnormality is performed, for example, after the diagnosis operation is finished. When the data center 2 has the above-mentioned determination function, the determination of the presence or absence of an abnormality is performed, for example, after the processing of S105.

4 is a flowchart showing another operation example of the control device 18 . In the control device 18, it is determined whether or not communication with the maintenance terminal 40 is possible (S201).

A maintenance person performs maintenance work of the elevator 1 regularly or irregularly. The maintenance person carries the maintenance terminal 40 when performing maintenance work. The maintenance person carries the maintenance terminal 40 and enters the hoistway 12 . When the elevator 1 has a machine room, the maintenance person enters the machine room carrying the maintenance terminal 40 .

5 is a diagram showing an example of the maintenance terminal 40 . The maintenance terminal 40 is equipped with the thermometer 41 and the communication part 42, for example. The communication unit 42 communicates with the control device 18 . For example, if the maintenance terminal 40 is connected to the control apparatus 18, it will determine with Yes in S201. The communication unit 42 may communicate with the control device 18 via the communication device 26 . The communication unit 42 may communicate with the control device 18 through the device provided in the car 10 . The communication unit 42 may communicate wirelessly with the control device 18 .

If it is determined with Yes in S201, it is determined in the control apparatus 18 whether the maintenance terminal 40 exists in the hoistway 12 (S202). For example, if the control apparatus 18 is provided in the hoistway 12 and the maintenance terminal 40 is wired to the control apparatus 18, it will determine with Yes in S202. When the maintenance person is carrying the maintenance terminal 40, for example, if the specific switch arrange|positioned in the hoistway 12 is operated, it determines with Yes in S202. As another example, if the maintenance switch provided on the car 10 is operated, it will determine with Yes in S202.

If it is determined as Yes in S202, the temperature acquisition part 32 acquires the actually measured value of the temperature measured by the thermometer 41 (S203). The value obtained in S203 is an actual measured value of the temperature of the hoistway 12 . The measured value of the temperature acquired by the temperature acquisition unit 32 is transmitted to the data center 2 (S204).

As shown in FIG. 1 , the data center 2 includes, for example, a storage unit 50 , a fluctuation calculation unit 51 , a transition specifying unit 52 , and a communication unit 53 . Hereinafter, a function of the data center 2 will be described with reference to FIGS. 6 to 9 as well. 6 is a flowchart showing an operation example of the data center 2 .

In the data center 2, it is determined whether the value measured by the measurement unit 31 has been received from the elevator 1 (S301). The measurement value transmitted from the elevator 1 in S105 is received by the communication unit 53 . When the communication unit 53 receives the measurement value from the elevator 1, it stores the received measurement value in the storage unit 50 (S302). Thereby, the value measured by the measurement unit 31 in the diagnostic operation is stored in the storage unit 50 . That is, in the storage unit 50, a value relating to the operation of the car 10 and a value relating to a specific device are stored.

The diagnostic operation is performed regularly, for example. The storage unit 50 periodically stores the minimum voltage value Vmin of the battery 25 measured in the diagnostic operation. As another example, the moving distance L1 of the car 10 measured in the diagnostic operation is periodically stored in the storage unit 50 . As another example, the moving distance L2 of the car 10 measured in the diagnostic operation is periodically stored in the storage unit 50 .

Moreover, in the data center 2, it is determined whether the temperature acquisition part 32 has received the measured value of the acquired temperature from the elevator 1 (S303). The actually measured value of the temperature transmitted from the elevator 1 in S204 is received by the communication unit 53 . When the communication unit 53 receives the measured temperature value from the elevator 1, it stores the received measured value in the storage unit 50 (S304). Thereby, the actual measured value of the temperature of the hoistway 12 measured by the thermometer 41 is memorize|stored in the memory|storage part 50 . A maintenance worker performs maintenance work regularly, for example. The storage unit 50 periodically stores the measured value of the temperature of the hoistway 12 measured by the thermometer 41 .

7 is a flowchart showing another operation example of the data center 2 . For example, the minimum voltage value Vmin of the battery 25 measured in the diagnostic operation is stored in the storage unit 50 . The fluctuation calculation unit 51 reads the minimum voltage value Vmin of the battery 25 from the storage unit 50 (S401).

FIG. 8 is a diagram showing changes with time of the minimum voltage value Vmin of the battery 25. As shown in FIG. The curve A shown in FIG. 8 shows the change with time of the minimum voltage value Vmin measured in the diagnostic operation of a certain elevator A. As shown in FIG. The curve B shows the change with time of the measured minimum voltage value Vmin in the diagnostic operation of another elevator B.

As shown in FIG. 8, a long-term fluctuation component and a seasonal fluctuation component are contained in the temporal change of the minimum voltage value Vmin. The long-term fluctuation component mainly occurs due to deterioration of the battery 25 . For example, as the battery 25 deteriorates, the minimum voltage value Vmin gradually decreases with the passage of time. On the other hand, a seasonal variation component mainly originates in the change of the temperature of the hoistway 12 in which the battery 25 is installed. For example, the minimum voltage value Vmin becomes a large value in summer when the temperature of the hoistway 12 becomes high, and becomes a small value in winter when the temperature of the hoistway 12 decreases.

The fluctuation calculation unit 51 calculates the seasonal fluctuation component of the temporal change by removing the long-term fluctuation component from the temporal change of the minimum voltage value Vmin (S402). For example, the fluctuation calculation unit 51 calculates a difference between the minimum voltage value measured in one month and the minimum voltage value measured in the same month of the following year as a long-term fluctuation component. The fluctuation calculation unit 51 may calculate a value obtained by averaging the differences for a plurality of months as a long-term fluctuation component. The fluctuation calculation unit 51 may calculate the difference between the maximum value of the minimum voltage value measured in one year and the maximum value of the minimum voltage value measured in the next year as a long-term fluctuation component. The fluctuation calculation unit 51 may calculate the difference between the minimum value of the minimum voltage value measured in one year and the minimum value of the minimum voltage value measured in the next year as a long-term fluctuation component. Moreover, the fluctuation|variation calculation part 51 may calculate|require a long-term fluctuation component by identifying the prediction model which has a long-term fluctuation component and a periodic fluctuation component by a statistical method. As the predictive model, for example, a model expressed as a sum of a component expressed by a linear function or a quadratic function and a component expressed by a trigonometric function can be employed. As the predictive model, another model may be employed.

The fluctuation calculation unit 51 may calculate the period and amplitude of the seasonal fluctuation component in S402. The calculated amplitude of the seasonal variation component corresponds to the difference between the summer temperature and the winter temperature of the hoistway 12 .

Next, the transition specifying unit 52 reads an actual measured value of the temperature of the hoistway 12 from the storage unit 50 (S403). The transition specifying unit 52 specifies the temperature transition of the hoistway 12 based on the seasonal variation component of the temporal change of the minimum voltage value Vmin calculated in S402 and the actual measured value of the temperature read in S403 (S404).

9 is a diagram for explaining the function of the transition specifying unit 52 . For example, the first conversion table for converting the seasonal variation component of the temporal change of the minimum voltage value Vmin into the relative temperature transition is stored in the storage unit 50 in advance. The transition specifying unit 52 converts the seasonal variation component calculated in S402 into a relative temperature transition by using the first conversion table. Further, the transition specifying unit 52 determines the offset value of the relative temperature transition based on the actually measured value of the temperature read in S403 . Thereby, the transition specifying unit 52 specifies the absolute temperature transition of the hoistway 12 . Below, the thing of absolute temperature transition is simply called "temperature transition".

In FIG. 9 , the temperature transition of the hoistway 12 specified by the transition specifying unit 52 is indicated by a curve C. As shown in FIG. If the curve C can be specified, it is possible to estimate the temperature of the hoistway 12 on specific days in the past and in the future. Incidentally, if the temperature measured and the estimated temperature when a maintenance worker visits do not match, the actual temperature may be obtained by a probabilistic model.

In the example shown in this embodiment, the temperature transition of the hoistway 12 is specified using the minimum voltage value Vmin of the battery 25. As shown in FIG. The minimum voltage value Vmin of the battery 25 is a value measured in the diagnostic operation. For this reason, if it is the example shown in this embodiment, the temperature transition of the hoistway 12 can be specified without permanently installing a new measuring device. In the maintenance and inspection, the maintenance items are not increased.

In this embodiment, in order to specify the temperature transition of the hoistway 12, the example which uses the minimum voltage value Vmin of the battery 25 is demonstrated. This is an example. You may specify the temperature transition of the hoistway 12 using the moving distance L1 of the car 10 by the same method as the above-mentioned specific method. You may specify the temperature transition of the hoistway 12 using the movement distance L2 of the cage|basket|car 10. Incidentally, the battery 25 is not a device used in normal operation. For this reason, when using the minimum voltage value Vmin of the battery 25, there exists an advantage that the temperature transition of the hoistway 12 can be specified without being influenced by the number of times of running of the car 10, etc.

In this embodiment, the example of specifying the temperature transition of the hoistway 12 using the actually measured value of the temperature of the hoistway 12 was demonstrated. The hoistway 12 is an example of an elevator space in which the device is installed. When the elevator 1 has a machine room, the elevator space may be a machine room. That is, the transition specifying unit 52 may specify the temperature transition in the machine room using the actually measured value of the temperature of the machine room measured by the thermometer 41 . In this case, in S202, it is determined whether the maintenance terminal 40 exists in the machine room. If it determines with Yes in S202, the temperature acquisition part 32 acquires the actually measured value of the temperature measured with the thermometer 41. As shown in FIG.

In addition, the difference between the temperature of the hoistway 12 and the temperature of the machine room is relatively small in many cases. For this reason, the transition specifying part 52 may use the actually measured value of the temperature of the hoistway 12 measured with the thermometer 41, and may specify the temperature transition of a machine room. The transition specifying unit 52 may specify the temperature transition of the hoistway 12 based on the actually measured value of the temperature of the machine room measured by the thermometer 41 . That is, the transition specifying unit 52 specifies the temperature transition in the elevator space using the actually measured value of the temperature in the elevator space measured by the thermometer 41 .

Next, an example of constructing a maintenance planning system using the temperature transition specification function provided in the data center 2 will be described. 10 is a diagram showing another example of the data center 2 . The data center 2 shown in FIG. 10 includes, in addition to the storage unit 50 , the fluctuation calculation unit 51 , the transition specifying unit 52 , and the communication unit 53 , for example, a lifespan calculation unit 54 , and A determination unit (55) is further provided. 11 is a diagram showing another operation example of the data center 2 . The operation shown in Fig. 11 is performed, for example, after the operation shown in Fig. 7 .

When the temperature transition of the elevator space is specified in S404, the life calculation unit 54 calculates the life of the parts arranged in the elevator space (S501). For example, the lifetime calculation unit 54 performs a simulation of component deterioration based on the temperature transition specified by the transition specifying unit 52 and the running history of the car 10 , and calculates the lifetime of the component. The running history of the car 10 may be the number of running times of the car 10 or the running distance of the car 10 . For example, the life calculation unit 54 calculates the lifetime of the electric component disposed inside the control device 18 . The lifetime calculation unit 54 may calculate the lifetime of resin parts, such as a belt.

The determination unit 55 determines the inspection timing of the parts (S502). The determination unit 55 determines the inspection timing based on the lifetime of the parts calculated by the life calculation unit 54 . The determination unit 55 may determine the replacement timing of parts in S502. Thereby, it is possible to create an appropriate maintenance plan according to the inspection time or replacement time of parts.

12 is a diagram showing another example of the data center 2 . In the data center 2 shown in Fig. 12, in addition to the storage unit 50, the fluctuation calculation unit 51, the transition specifying unit 52, and the communication unit 53, for example, a category determination unit 56, and a board A government (55) is further provided. 13 is a diagram showing another operation example of the data center 2 . The operation shown in Fig. 13 is performed, for example, after the operation shown in Fig. 7 .

If the temperature trend of the elevator space is specified in S404, the category determining unit 56 determines the environmental category to which the elevator space belongs (S601). For example, the environment of the elevator space differs depending on the structure of the building in which the elevator 1 is installed. Moreover, the environment of the elevator space differs with the position and direction in which the elevator 1 is installed. For example, when the elevator 1 is installed in the central part of a large-scale building, the temperature of the elevator space is constant throughout the year. Moreover, when the elevator 1 is provided in the position where outside air is easy to enter, the temperature of the elevator space is easily influenced by the outside air temperature. When the elevator 1 is a so-called see-through elevator and is installed in a position receiving direct sunlight, the temperature of the elevator space changes larger than the change in the outside temperature.

In the examples shown in FIGS. 12 and 13 , a plurality of environment categories are preset. Further, a first classification condition for determining the environmental category to which the elevator space belongs is preset. The category determining unit 56 determines the environmental category based on the temperature transition specified by the transition specifying unit 52 and the first classification condition. For example, the category determining unit 56 calculates characteristic quantities such as the highest temperature, the lowest temperature, the period of the transition, and the amplitude of the transition from the specified temperature transition. The category determining unit 56 applies the calculated feature amount to the first classification condition to determine the environmental category.

The determination unit 55 determines the inspection timing of the parts (S602). The determination unit 55 determines the inspection timing of the parts arranged in the elevator space based on the environmental category of the elevator space determined by the category determination unit 56 . For example, the inspection cycle of parts is preset for each environmental category. The determination unit 55 may determine the replacement timing of parts in S602. Thereby, it is possible to create an appropriate maintenance plan according to the inspection time or replacement time of parts.

14 is a diagram showing another example of the data center 2 . In the data center 2 shown in FIG. 14 , in addition to the storage unit 50 , the fluctuation calculation unit 51 , the trend specifying unit 52 , and the communication unit 53 , for example, a category determination unit 56 , a trend It further includes a specifying unit 57 , a lifetime calculating unit 54 , and a determining unit 55 . 15 is a diagram showing another operation example of the data center 2 . The operation shown in Fig. 15 is performed, for example, after the operation shown in Fig. 7 .

When the temperature transition of the elevator space is specified in S404, the category determining unit 56 determines the environmental category to which the elevator space belongs (S701). In the examples shown in FIGS. 14 and 15 , the category determination unit 56 determines the environmental category based on the difference between the temperature transition and the outside temperature specified by the transition specifying unit 52 . The outside air temperature can be obtained, for example, from an external organization such as the Meteorological Agency. The category determination unit 56 determines the environmental category based on the difference between the temperature of the elevator space on one day and the outside temperature on that day estimated from the temperature transition.

For example, when an air conditioner is provided in an elevator space, the vehicle fluctuates according to the season. When the elevator 1 is installed in a position where outside air is likely to enter, the car becomes relatively small throughout the year. The difference also varies depending on the material of the wall forming the hoistway 12 .

In the examples shown in FIGS. 14 and 15 , a plurality of environment categories are preset. Further, a second classification condition for determining the environmental category to which the elevator space belongs is preset. The category determining unit 56 determines the environmental category, for example, based on the difference and the second classification condition.

Moreover, in the example shown in FIG. 14 and FIG. 15, the 2nd conversion table for each environment category is stored in the storage part 50 beforehand. The second conversion table is a table for converting the humidity of the outside air into the humidity of the elevator space. For example, in order to create a second conversion table, the humidity of various elevator spaces is actually measured. The 2nd conversion table is created in advance using the measured value of the humidity of an outside air humidity and the humidity of an elevator space, and is memorize|stored in the memory|storage part 50. The outside air humidity can be obtained, for example, from an external organization such as the Meteorological Agency.

The transition specifying unit 57 specifies the humidity transition in the elevator space based on the environmental category determined by the category determining unit 56 . 16 is a diagram for explaining the function of the transition specifying unit 57 . 16 shows an example in which the humidity trend is specified using the second conversion table of the environment category in which the building is equipped with air conditioning equipment but the hoistway 12 is not equipped with air conditioning equipment. For example, the transition specifying unit 57 reads the corresponding second conversion table from the storage unit 50 (S702). That is, the transition specifying unit 57 reads from the storage unit 50 the second conversion table corresponding to the environment category determined by the category determining unit 56 in S702 . The transition specifying unit 57 uses the read second conversion table to specify the humidity transition in the elevator space (S703).

If the humidity trend of the elevator space is specified in S703, the life calculation unit 54 calculates the life of the parts arranged in the elevator space (S704). For example, the life calculation unit 54 is configured to deteriorate parts based on the temperature transition specified by the transition specification unit 52 and the humidity transition specified by the transition specification unit 57 and the running history of the car 10 . simulation to calculate the lifetime of the part. The running history of the car 10 may be the number of running times of the car 10 or the running distance of the car 10 .

The determination unit 55 determines the inspection timing of the parts (S705). The determination unit 55 determines the inspection timing based on the lifetime of the parts calculated by the life calculation unit 54 . The determination unit 55 may determine the replacement timing of parts in S705. Thereby, it is possible to create an appropriate maintenance plan according to the inspection time or replacement time of parts.
