Detailed Description
A mode for carrying out the present invention will be described with reference to the accompanying drawings. The same or corresponding portions are denoted by the same reference numerals in the respective drawings, and overlapping description is appropriately simplified or omitted.
Fig. 1 is a configuration diagram of a startup count measurement system according to embodiment 1.
The system 1 for measuring the number of times of activation is applied to an elevator 2.
The elevator 2 is installed in the building 3. The building 3 includes a plurality of floors. In the elevator 2, a hoistway 4 penetrates each floor of the building 3.
The elevator 2 includes a hoisting machine 5, a main rope 6, a counterweight 7, a car 8, and a control panel not shown. The hoisting machine 5 is installed in the hoistway 4, for example. The hoisting machine 5 includes a motor and a sheave. The motor of the hoisting machine 5 is a device that generates driving force. The sheave of the hoisting machine 5 is rotated by a driving force generated by a motor. The main ropes 6 are wound around a sheave of the hoisting machine 5. The main ropes 6 move following the rotation of the sheave of the hoisting machine 5. One end of the main rope 6 is provided to the car 8, for example. The other end of the main rope 6 is provided to the counterweight 7, for example. The counterweight 7 is a device that balances the car 8, which is a load applied to both sides of the sheave of the hoisting machine 5 by the main ropes 6. The car 8 is a device as follows: the vehicle travels in the vertical direction inside the hoistway 4 following the movement of the main rope 6, thereby transporting users and the like between a plurality of floors of the building 3. The car 8 includes a car door 9. The car door 9 is a device that opens and closes when the car 8 stops at any of a plurality of floors so that a user can get on and off the car 8. The control panel is a device for controlling the operation of the elevator 2. The operation of the elevator 2 includes the travel of the car 8. The control panel is installed in the hoistway 4, for example.
In the elevator 2, a landing 10 is provided on each floor of the building 3. The landing 10 communicates with the hoistway 4 through a landing doorway. The landing doorway is an opening connecting the landing 10 and the hoistway 4. The elevator 2 includes a landing door 11. The landing door 11 is provided at a landing doorway. The landing doors 11 are devices that open and close in conjunction with the car doors 9 so that a user can get on and off the car 8.
In the maintenance of the elevator 2, the life of the main ropes 6 is calculated. The life of the main ropes 6 is used to determine, for example, the replacement timing of the main ropes 6. The life of the main ropes 6 may be affected by wear and fatigue caused by contact between the main ropes 6 and sheaves of the hoisting machine 5, for example. The life of the main ropes 6 is thus calculated e.g. from the number of starts of the elevator 2. The number of times of starting the elevator 2 is measured once, for example, when the car 8 stopped at the departure floor stops at the arrival floor after traveling in the hoistway 4. The departure floor is any one of a plurality of floors. The arrival floor is a floor different from the departure floor in any one of a plurality of floors.
Alternatively, the life of the main ropes 6 is calculated e.g. from the number of starts of the elevator 2 from the main floor to the main direction. The main floor is a predetermined one of the floors in the elevator 2. The main floor is, for example, a hall floor having a large number of users of the elevator 2. The main floor is for example 1 floor. The main direction is a traveling direction of the car 8 predetermined in the elevator 2. The main direction is, for example, a direction in which users who depart from the main floor use a lot. In the case where the main floor is the 1 st floor, the main direction is, for example, the upward direction.
The start-up count measuring system 1 includes a start-up count measuring device 12. In this example, the control panel of the elevator 2 does not have a function of outputting information necessary for measuring the number of times of starting from the main floor in the main direction. In this case, the start count measuring device 12 is applied to the elevator 2. The number-of-starts measuring device 12 is a device that measures the number of starts of the elevator 2. The start-up count measuring device 12 is provided, for example, in an upper portion of the outside of the car 8. In this example, the start count measuring device 12 is not connected to the control panel of the elevator 2. The number-of-activation measurement device 12 includes a housing 13 and a measurement unit 14.
The housing 13 constitutes an outer contour of the start count measuring device 12. The housing 13 is mounted on the outside of the car 8. The housing 13 is mounted, for example, on the upper beam of the car 8. The upper beam of the car 8 is formed of a ferrous metal material, for example. The upper beam of the car 8 is disposed outside the car 8. The housing 13 includes a magnet 15. The magnet 15 is provided on the bottom surface of the housing 13. The magnet 15 is attached to the outside of the car 8 by magnetic force. The magnet 15 is an example of the mounting portion. The housing 13 is mounted so as to be movable integrally with the car 8 by means of a magnet 15.
The measurement unit 14 is housed in the case 13. The measuring unit 14 is provided so as to be movable integrally with the car 8 via a magnet 15 of the casing 13. The measurement unit 14 is a device that acquires travel information of the car 8. The measurement unit 14 includes an accelerometer 16 and an altimeter 17.
The accelerometer 16 is a device that measures acceleration. The acceleration measured by the accelerometer 16 is the acceleration of the car 8. The acceleration measured by the accelerometer 16 is an example of the travel information of the car 8 acquired by the measurement unit 14.
The height gauge 17 is a device for measuring the height in the hoistway 4. The altimeter 17 is, for example, a barometric altimeter that calculates the altitude from the absolute barometric pressure measured by the barometric pressure sensor. The altimeter 17 is, for example, a radio altimeter that measures a reflection time from a target object by using a radio wave to calculate a distance to the target object. The target object is, for example, a ceiling portion of the hoistway 4. The height meter 17 may calculate the height from the distance to the target object. The height in the hoistway 4 is, for example, a height from a lower end of the hoistway 4. The height measured by the height gauge 17 corresponds to the position of the car 8. The height measured by the height gauge 17 is an example of the travel information of the car 8 acquired by the measuring unit 14.
When the car 8 stops at any floor, the start count measuring device 12 is located at a height corresponding to the floor. For example, when the car 8 stops at floor 1, the start count measuring device 12 is located at a height H1 corresponding to floor 1. When the car 8 stops at the 2 th floor, the start count measuring device 12 is located at the height H2 corresponding to the 2 nd floor.
The activation count measuring device 12 stores the height ranges corresponding to the plurality of floors. For example, the activation count measuring device 12 stores the height range R1 including the height H1 as a height range corresponding to 1 layer. For example, the activation count measuring device 12 stores the height range R2 including the height H2 as a height range corresponding to 2 levels.
Next, the structure of the start-up count measuring device 12 will be described with reference to fig. 2.
Fig. 2 is a configuration diagram of the startup count measuring device according to embodiment 1.
The number-of-starts measuring device 12 includes a counting unit 18, a storage unit 19, an external terminal 20, a battery 21, a power switch 22, a measurement mode switch 23, an altimeter initial setting switch 29, and a display device 24.
The counting section 18 is housed in the case 13. The counting unit 18 is a part that counts the number of times of starting the elevator 2 based on the travel information of the car 8 acquired by the measuring unit 14.
The storage portion 19 is housed in the case 13. The storage unit 19 is a part that stores information on the number of times the elevator 2 is started, which is measured by the counting unit 18. The storage unit 19 is an external storage medium such as an SD card, for example. At this time, the housing 13 has a slot on an outer surface to which an external storage medium is connected.
The external terminal 20 is provided on the outer surface of the housing 13. The external terminal 20 is a terminal capable of receiving power supply for operating the start-up count measuring device 12 from an external power supply. The external terminal 20 is a terminal capable of communicating information with an external device. The external terminal 20 is, for example, a USB (Universal Serial Bus) socket.
The battery 21 is housed in the case 13. The battery 21 is a storage battery that supplies power to operate the start count measuring device 12 when the external terminal 20 does not receive power from an external power supply. The battery 21 is connected to the external terminal 20 so as to be charged with electric power received from the outside by the external terminal 20.
The power switch 22 is provided on the outer surface of the housing 13. The power switch 22 is a switch for operating the start-up count measuring device 12 in the on state.
The measurement mode switch 23 is provided on the outer surface of the housing 13. The measurement mode switch 23 is a switch for switching the operation mode of the start-up count measuring device 12. The number-of-starts measuring device 12 measures the number of times of starting the elevator 2 when the operation mode is the measurement mode. The number-of-starts measuring device 12 receives a setting for measuring the number of starts of the elevator 2 when the operation mode is, for example, the standby mode.
The altimeter initial setting switch 29 is a switch for correcting the height measured by the altimeter 17 to the height of the floor at which the car 8 is stopping when the start count measuring device 12 is installed in the car 8. The floor at which the car 8 is stopping is selected by, for example, the number of times the altimeter initial setting switch 29 is pressed within a predetermined time. For example, when the altimeter initial setting switch 29 is pressed twice within a predetermined time when the start-up number measuring device 12 is installed in a state where the car 8 is stopped at the 2 th floor, the height measured by the altimeter 17 is corrected to the height H2 corresponding to the 2 nd floor.
The display device 24 is provided in the housing 13. The display device 24 is, for example, a plurality of LED (Light Emitting Diode) lamps. The display device 24 includes, for example, a "power source" lamp indicating that the start count measuring device 12 is operating. The display device 24 includes, for example, a "normal/abnormal" lamp indicating whether or not the start count measuring device 12 is operating normally. The display device 24 includes a "battery capacity low" lamp indicating that the capacity of the battery 21 is low. The display device 24 includes, for example, a "measurement" lamp indicating that the operation mode of the start count measuring device 12 is the measurement mode.
The startup count measuring system 1 includes a conversion adapter 25, a terminal device 26, and a maintenance server 27. The conversion adapter 25 or the terminal device 26 is connected to the external terminal 20 of the start-up count measuring device 12. The start-up count measuring device 12 may be provided with a plurality of external terminals 20 so that the conversion adapter 25 and the terminal device 26 can be connected to each other.
The conversion adapter 25 is a device that converts electric power supplied from an external power supply and supplies the converted electric power to the activation count measuring device 12. The conversion adapter 25 is, for example, an AC (Alternating Current) adapter that converts AC power from a commercial power supply into dc power. The conversion adapter 25 is connected to, for example, a socket provided in an upper portion outside the car 8.
The terminal device 26 is a device to which dedicated software corresponding to the startup count measuring device 12 is installed. The terminal device 26 is, for example, a personal computer. The dedicated software is, for example, software for setting the start count measuring device 12 and processing the start count information.
The maintenance server 27 is connected to the terminal device 26 via the network 28. The maintenance server 27 is a server that manages maintenance information of the elevator 2 and other elevators. The maintenance server 27 is provided outside the building 3, for example. The maintenance information includes, for example, a maintenance result and maintenance schedule information. The maintenance result information includes, for example, startup count information. The maintenance schedule information includes, for example, maintenance timing, maintenance contents, and information on whether or not maintenance is performed.
Next, a method of measuring the number of times of starting the elevator 2 will be described with reference to fig. 2.
First, before the maintenance person measures the number of times of starting the elevator 2, the maintenance person sets the starting number measuring device 12 using dedicated software. At this time, the start-up count measuring device 12 is connected to the maintenance terminal through the external terminal 20. The power switch 22 is in an on state. The operation mode of the start count measuring device 12 is a standby mode. The maintenance worker starts connection of the start-up count measuring device 12 and the terminal device 26 by using dedicated software. The maintenance person sets, for example, a COM port to which the terminal device 26 of the start-up count measuring device 12 is connected. The start-up count measuring device 12 operates using the power supplied from the terminal device 26.
The maintenance worker uses dedicated software to set the measurement of the start-up count measuring device 12. The measured setting includes setting of the main floor and the main direction. The measurement setting includes setting of measurement parameters and setting of the current time. The setting of the measurement parameters includes setting of the height Hn corresponding to each floor of the building 3 and setting of the range Rn including the height Hn. Here, the height Hn corresponds to n floors of the building 3. The range Rn includes the height Hn. In this case, the maintenance worker may perform setting by registering, calling, or the like of a predetermined set value. The maintenance worker disconnects the startup count measuring device 12 from the terminal device 26 by using dedicated software. The power switch 22 is switched to the off state.
Next, the maintenance worker performs the work of the mounting process. For example, the installation process is performed in a state where the car 8 is stopped at floor 1. In the mounting process, the maintenance worker places the start-up count measuring device 12 on the upper beam of the car 8. The start count measuring device 12 is attached to the upper beam of the car 8 by the magnetic force of the magnet 15. The start-up count measuring device 12 is connected to a socket provided in an upper portion outside the car 8 via a conversion adapter 25 by an external terminal 20. At this time, the power switch 22 is in an on state. The maintenance person presses the altimeter initial setting switch 29 1 time within a prescribed time. Thus, the height measured by the height meter 17 is corrected to the height H1 corresponding to 1 floor. The operation mode of the start-up count measuring device 12 is switched to the measurement mode. The start-up count measuring device 12 operates using the power supplied from the conversion adapter 25.
During the subsequent measurement period, the elevator 2 operates as usual. The measurement period is a period in which the number of times of starting the elevator 2 is measured. The measurement period is a predetermined period of 2 weeks or more, for example. During the measurement period, the car 8 travels between a plurality of floors in response to a call from a user.
At this time, the measuring unit 14 of the start count measuring device 12 moves integrally with the car 8. The accelerometer 16 of the measurement unit 14 measures acceleration. The measurement unit 14 acquires the acceleration measured by the accelerometer 16 as the travel information of the car 8. The height gauge 17 measures the height in the hoistway 4. The measuring unit 14 acquires the height measured by the height gauge 17 as the travel information of the car 8.
The counting unit 18 measures the number of times of starting the elevator 2 based on the travel information of the car 8 acquired by the measuring unit 14. The counter 18 determines whether the elevator 2 is started or not based on the acceleration measured by the accelerometer 16. When determining that the elevator 2 is started, the counting unit 18 determines which floor is the departure floor and the arrival floor based on the altitude measured by the altitude meter 17. The counting unit 18 measures the number of times of starting of the elevator 2 for each set of the departure floor and the arrival floor. The counting unit 18 adds 1 to the number of times of starting of the elevator 2 of each group of the determined departure floor and arrival floor. In particular, when the departure floor is a main floor and the arrival floor is a floor located in the main direction from the departure floor, the counting unit 18 adds 1 to the number of times of starting the elevator 2 from the main floor to the main direction.
The storage unit 19 stores the number of times of starting the elevator 2 measured by the counting unit 18. The storage unit 19 stores, for example, the number of times of starting the elevator 2 for each set of departure floors and arrival floors. The storage unit 19 stores, for example, the number of times of starting the elevator 2 from the main floor in the main direction. For example, the number of times of starting the elevator 2 stored in the storage unit 19 is updated every time the counting unit 18 determines that the elevator 2 is started.
After the measurement period, the maintenance worker performs the operation of the recovery process. In the recovery step, the maintenance worker recovers the start-up count measuring device 12 from the upper beam of the car 8. The operation mode of the start-up count measuring device 12 is switched to the standby mode. The power switch 22 is switched to the off state.
In the recovery step, the start-up count measuring device 12 is connected to the terminal device 26 through the external terminal 20. At this time, the power switch 22 is in an on state. The operation mode of the start count measuring device 12 is a standby mode. In the recovery process, the maintenance worker obtains the information on the number of times of starting the elevator 2 stored in the storage unit 19 by using dedicated software.
Next, the maintenance person performs processing of the acquired information on the number of times of activation of the elevator 2 by using the dedicated software. The maintenance person deletes the information on the number of times of activation of the elevator 2 from the storage unit 19. The maintenance personnel save the acquired information. The maintenance personnel may also print the retrieved information using dedicated software. The maintenance person may also convert the data format of the acquired information using dedicated software. The data form is, for example, the CSV (Comma-Separated Values: Comma Separated Values) form.
The maintenance person may add unique information to the acquired information. The unique information is information unique to measurement of the acquired information. The unique information includes, for example, an identification number of the elevator 2 whose number of times of starting has been measured, a name of the building 3 in which the elevator 2 is installed, a measurement period, and the like.
The terminal device 26 may convert the acquired information on the number of times of starting the elevator 2 into information on the number of times corresponding to a measurement period of a standard length by using dedicated software. The standard length measurement period is, for example, 2 weeks. The terminal device 26 performs conversion by multiplying the acquired number of times of activation by the ratio of the actual measurement period length to the standard measurement period length, for example.
The terminal device 26 transmits the information processed by the dedicated software to the maintenance server 27.
The maintenance server 27 calculates the life of the main rope 6 based on the number of times the elevator 2 is started, which is included in the received information. In particular, when the received information includes the number of times of activation of the elevator 2 from the main floor in the main direction, the maintenance server 27 calculates the life of the main rope 6 based on the number of times. The maintenance server 27 stores the calculated life of the main rope 6 as information of the maintenance result, for example.
The maintenance server 27 updates the maintenance schedule when receiving the information from the terminal device 26. The maintenance server 27 registers, for example, the completion of the measurement of the number of times of activation as maintenance schedule information. The maintenance server 27 registers, for example, the time when the next number of times of activation is measured as maintenance schedule information. The maintenance server 27 may set the time for the next number of times of starting to measure based on the calculated life of the main rope 6.
Next, an example of the number of times of activation measurement performed by the activation number measurement device 12 will be described with reference to fig. 3.
Fig. 3 is a diagram showing an example of the number of times of activation measurement performed by the activation number measurement device according to embodiment 1.
The graph G shows an example of a temporal change in the acceleration of the car 8 when the car 8 that had stopped at the departure floor stops at the arrival floor after traveling in the hoistway 4. The horizontal axis of graph G represents time. The vertical axis of the graph G indicates the acceleration in the same direction as the traveling direction of the car 8. That is, when the car 8 travels in the upward direction, the vertical axis of the graph G indicates the acceleration positive in the upward direction. When the car 8 travels in the downward direction, the vertical axis of the graph G indicates an acceleration that is positive in the downward direction.
The car 8 that had stopped at the departure floor starts traveling in the upward direction, for example, in response to a call of a user.
Then, the acceleration of the car 8 increases in the positive direction. The counting unit 18 determines whether or not the magnitude of the acceleration in the positive direction of the car 8 exceeds the magnitude of the positive threshold. The positive threshold is a predetermined value of acceleration. Positive thresholds are examples of measured parameters. When the magnitude of the acceleration in the positive direction of the car 8 exceeds the magnitude of the positive threshold, the counting unit 18 determines whether or not the state in which the acceleration exceeds the positive threshold continues for a time longer than the acceleration continuation determination time. The acceleration duration determination time is a predetermined time. The acceleration duration determination time is an example of the measurement parameter.
Then, the magnitude of the acceleration of the car 8 is reduced. The car 8 travels toward the arrival floor at a constant speed.
Then, the acceleration of the car 8 increases in the negative direction. The counting unit 18 determines whether or not the magnitude of the acceleration of the car 8 in the negative direction exceeds the magnitude of the negative threshold. The negative threshold is a predetermined value of acceleration. Negative thresholds are examples of measured parameters. When the magnitude of the acceleration of the car 8 in the negative direction exceeds the magnitude of the negative threshold, the counting unit 18 determines whether or not the state in which the acceleration exceeds the negative threshold continues for a time longer than the deceleration continuation determination time. The deceleration duration determination time is a predetermined time. The deceleration duration determination time is an example of the measurement parameter.
Then, the magnitude of the acceleration of the car 8 is reduced. The car 8 stops at the arrival floor.
The counting unit 18 determines that the elevator 2 is started when the magnitude of the positive acceleration exceeds the magnitude of the positive threshold for a time longer than the acceleration continuation determination time and then the magnitude of the negative acceleration exceeds the magnitude of the negative threshold for a time longer than the deceleration continuation determination time. At this time, the counting unit 18 adds 1 to the number of times of starting the elevator 2.
When determining that the elevator 2 is started, the counting unit 18 determines which of the plurality of floors the departure floor and the arrival floor are based on the altitude measured by the altitude meter 17.
The number-of-activation measurement device 12 stores height ranges corresponding to a plurality of floors. The counting unit 18 determines a floor corresponding to a range including the height of the altimeter 17 immediately before the start of the elevator 2 as a departure floor. The counting unit 18 determines a floor corresponding to a range of heights including the height meter 17 immediately after the elevator 2 is started and stopped as an arrival floor. When the departure floor is a main floor and the direction from the departure floor to the arrival floor is the main direction, the counting unit 18 determines that the elevator 2 has been started from the main floor in the main direction.
For example, when the height of the height gauge 17 immediately before the start of the elevator 2 is included in the range R1, the counting unit 18 determines that floor 1 is the starting floor. When the height of the height gauge 17 immediately after the elevator 2 is started and stopped is included in the range R2, the counting unit 18 determines that floor 2 is the arrival floor. In this example, the main floor is floor 1. The main direction is the up direction. At this time, the counting unit 18 determines that the elevator 2 is started from the main floor in the main direction. The counting unit 18 adds 1 to the number of times of starting the elevator 2 from the main floor in the main direction.
The height ranges corresponding to the plurality of floors are examples of the measurement parameter.
Next, an operation example of the start-up count measuring device 12 will be described with reference to fig. 4.
Fig. 4 is a flowchart showing an operation example of the startup count measuring device according to embodiment 1.
In step S1, the start count measuring device 12 receives the setting of the measurement. Thereafter, the operation of the start count measuring device 12 proceeds to step S2.
In step S2, the counting unit 18 determines whether the elevator 2 is started. If the determination result is "no", the operation of the start count measuring device 12 proceeds to step S2 again. If the determination result is yes, the operation of the start count measuring device 12 proceeds to step S3.
In step S3, the counting unit 18 determines the departure floor and the arrival floor. Thereafter, the operation of the start count measuring device 12 proceeds to step S4.
In step S4, the counter 18 adds 1 to the number of times of starting the elevator 2. The counting unit 18 adds 1 to the number of times of starting of the elevator 2 for each set of the departure floor and the arrival floor. When the departure floor is a main floor and the direction from the departure floor to the arrival floor is a main direction, the counting unit 18 adds 1 to the number of times of starting the elevator 2 from the main floor to the main direction. Thereafter, the operation of the start count measuring device 12 proceeds to step S2.
As described above, the number-of-activations measuring device 12 according to embodiment 1 includes the magnet 15, the measuring unit 14, and the counting unit 18. The magnet 15 is attached to the car 8 of the elevator 2. The measuring unit 14 moves integrally with the car 8 via the magnet 15. The measurement unit 14 acquires the travel information of the car 8. The counting unit 18 measures the number of times of starting the elevator 2 based on the travel information of the car 8 acquired by the measuring unit 14.
The start count measuring system 1 according to embodiment 1 includes a start count measuring device 12 and a terminal device 26. The start-up count measuring device 12 is attached to the car 8 of the elevator 2. The start count measuring device 12 moves integrally with the car 8. The number-of-starts measuring device 12 acquires the travel information of the car 8. The number-of-starts measuring device 12 measures the number of starts of the elevator 2 based on the acquired travel information of the car 8. The terminal device 26 acquires information on the number of times of activation of the elevator 2 measured by the activation number measuring device 12.
The method for measuring the number of times of activation according to embodiment 1 includes a mounting step and a collecting step. In the mounting step, the start-up count measuring device 12 is mounted on the car 8 before a predetermined measurement period. In the recovery step, after the measurement period, the information on the number of times of starting the elevator 2 in the measurement period measured by the number-of-times-of-starting measuring device 12 is acquired from the number-of-starting measuring device 12.
The start count measuring device 12 moves integrally with the car 8. The number-of-starts measuring device 12 acquires the travel information of the car 8. The number-of-starts measuring device 12 measures the number of starts of the elevator 2 based on the acquired travel information of the car 8. This enables the number of times of starting to be measured even for an elevator 2 for which the required information is not output from the control panel.
The start-up count measuring device 12 does not acquire information from the control panel of the elevator 2. The start count measuring device 12 moves integrally with the car 8, and directly obtains the travel information of the car 8 from the movement of the car 8. Thus, the start count measuring device 12 can measure the start count regardless of the model of the elevator 2 or the like.
The maintenance person can obtain the information on the number of times of starting the elevator 2 by installing and collecting the starting number measuring device 12 on site. This simplifies the operation of measuring the number of times of activation.
The measurement unit 14 includes an accelerometer 16 that measures acceleration. The measurement unit 14 acquires the acceleration measured by the accelerometer 16 as the travel information of the car 8.
The measurement unit 14 directly obtains acceleration information of the car 8 from the movement of the car 8 by moving integrally with the car 8. Thus, the measuring unit 14 can acquire the acceleration information of the car 8 regardless of the information from the control panel of the elevator 2. The measurement unit 14 can determine the start of the elevator 2 regardless of information from the control panel of the elevator 2.
The counting unit 18 adds 1 to the number of times of starting the elevator 2 when the magnitude of the positive acceleration exceeds the magnitude of the positive threshold for a time longer than the acceleration continuation determination time and then the magnitude of the negative acceleration exceeds the magnitude of the negative threshold for a time longer than the deceleration continuation determination time. Positive acceleration is acceleration in the same direction as the direction of travel of the car 8 as measured by the accelerometer 16. Negative acceleration is acceleration in the opposite direction to the direction of travel of the car 8 as measured by the accelerometer 16.
The counting unit 18 measures the start of the elevator 2 while observing a temporal change in acceleration unique to the start of the elevator 2. The car 8 may vibrate due to a user riding in and out of the car 8. In addition, in maintenance work or the like, for example, when the car 8 is stopped at a position deviated from a plurality of floors, the car 8 may be operated at a low speed. The counting unit 18 can prevent the start of the elevator 2 from being measured by acceleration that is not caused by the normal start of the elevator 2. This improves the accuracy of measuring the number of times of starting the elevator 2.
The measuring unit 14 further includes an altimeter 17, and the altimeter 17 measures the height of the elevator 2 in the hoistway 4. The measuring unit 14 acquires the height measured by the height gauge 17 as the travel information of the car 8.
The measuring unit 14 directly obtains the position information of the car 8 from the movement of the car 8 by moving integrally with the car 8. Thus, the measuring unit 14 can acquire the position information of the car 8 regardless of the information from the control panel of the elevator 2.
The counting unit 18 determines the floor at which the car 8 is stopping, based on the height measured by the height gauge 17.
When determining that the elevator 2 is started, the counting unit 18 determines which floor is the departure floor and the arrival floor based on the altitude measured by the altitude meter 17. The counting unit 18 can determine the floor at which the car 8 is stopping regardless of information from the control panel of the elevator 2.
The counting unit 18 also measures the number of times of starting of the elevator 2 for each set of the departure floor and the arrival floor.
The life of the main ropes 6 can be calculated from the frequency of contact of each part of the main ropes 6 with the sheave of the hoisting machine 5. The portion of the main ropes 6 that contacts the sheave of the hoisting machine 5 is determined by the departure floor and the arrival floor. Therefore, the life of the main ropes 6 can be calculated with high accuracy from the number of times of starting the elevator 2 for each set of the departure floor and the arrival floor. In this way, the number-of-starts measuring device 12 can acquire information for calculating the life of the main rope 6 with higher accuracy.
The counting unit 18 also counts the number of times the elevator 2 is started from the main floor in the main direction.
The life of the main ropes 6 is mainly affected by the portions of the main ropes 6 where aging progresses most seriously. The portion where the aging of the main ropes 6 is likely to progress is a portion frequently in contact with the sheave of the hoisting machine 5. That is, the life of the main rope 6 can be calculated with high accuracy based on the number of times of activation in the main direction from the main floor in which a large number of main floors are used. The number of starts from the main floor in the main direction is represented by a single value. Therefore, a simple calculation formula can be used for calculating the life of the main rope 6 based on the number of times of activation from the main floor in the main direction. In this way, the number-of-starts measuring device 12 can acquire information for calculating the life of the main rope 6 more easily and with higher accuracy.
In the case where the elevator 2 is provided with a device for measuring the number of times of activation, the device may measure the number of times of activation using a signal of a relay that is excited and demagnetized only once in association with the activation of the elevator 2. In this case, the number of starts counted by the device is the number of starts regardless of the departure floor and the traveling direction. Even in the elevator 2, the number of times of starting from the main floor in the main direction can be measured regardless of information from the control panel.
The magnet 15 is attached to the outside of the car 8 by magnetic force.
Thus, the maintenance worker can install the start count measuring device 12 by simply placing it on, for example, the upper beam of the car 8. This simplifies the operation of measuring the number of times of activation. The start count measuring device 12 is mounted on the outside of the car 8. This can suppress, for example, a malfunction caused by the user coming into contact with the start-up count measuring device 12 by mistake.
The number-of-starts measuring system 1 further includes a maintenance server 27. The maintenance server 27 manages maintenance information including a maintenance plan. The maintenance server 27 updates the maintenance schedule when receiving the information from the terminal device 26. The terminal device 26 transmits the acquired information on the number of times of activation of the elevator 2 to the maintenance server 27.
The information on the number of starts of the elevator 2 is sent to the maintenance server 27. Thereby, the information is managed uniformly together with other elevator information. Therefore, the maintenance information is easily managed. The maintenance schedule is updated by the maintenance server 27 by communication of the information on the number of times of activation of the elevator 2. Therefore, the work load of the maintenance worker is reduced in the maintenance of the elevator 2.
The number-of-times-to-start measuring device 12 may be, for example, a general-purpose portable terminal on which a measuring application is mounted. The portable terminal is, for example, a smartphone. In this case, the smartphone is mounted with a case having a magnet 15, for example. The measurement unit 14 may acquire the acceleration and the height measured by the acceleration sensor and the height sensor of the smartphone as the travel information of the car 8.
When the car 8 stops at any of the plurality of floors, the measurement unit 14 may correct the height of the start count measurement device 12 to a height corresponding to the floor.
The measurement unit 14 may determine the height of the activation count measurement device 12 by, for example, double-integrating the time change of the acceleration obtained by the accelerometer 16. Thus, the measuring unit 14 can calculate the height of the car 8 without providing an altimeter.
The measurement unit 14 may obtain the acceleration of the activation count measuring device 12 by, for example, performing second order differentiation on the temporal change in altitude obtained by the altimeter 17. The counting unit 18 may determine that the elevator 2 is started based on a change in the height obtained by the height meter 17 within a predetermined time. For example, when the height measured by the height gauge 17 changes by 500mm or more in a period of 3 seconds, the counting unit 18 determines that the elevator 2 is started. The counting unit 18 may determine that the elevator 2 is stopped when the change in the altitude obtained by the altitude meter 17 during a predetermined time period is less than a predetermined value. For example, when the counting unit 18 determines that the change in the height obtained by the height meter 17 during, for example, 3 seconds is less than 100mm after the elevator 2 is started, it determines that the elevator 2 has stopped. Thus, the counting unit 18 can detect the start and stop of the elevator 2 without an accelerometer.
The measurement unit 14 may correct the measurement value of one of the accelerometer 16 and the altimeter 17 with respect to the other. For example, when the measurement value of the altimeter 17 varies although the accelerometer 16 does not detect acceleration, the measurement unit 14 may determine that the measurement value of the altimeter 17 varies due to external factors such as air pressure. For example, when the measurement value of the altimeter 17 varies although it is determined that the vehicle has stopped at the same floor based on the acceleration detected by the accelerometer 16, the measurement unit 14 may determine that the measurement value of the altimeter 17 varies due to external factors such as the atmospheric pressure. In this case, the measurement unit 14 may correct the measurement value of the altimeter 17 by setting, for example, an offset (offset).
The measuring unit 14 may include a speedometer that measures a relative speed with respect to the inner wall of the hoistway 4 or the guide rail, for example. The measuring unit 14 may acquire the speed measured by the speedometer as the travel information of the car 8.
Next, an example of the hardware configuration of the startup count measuring device 12 will be described with reference to fig. 5.
Fig. 5 is a diagram showing a hardware configuration of a main part of the start count measuring device according to embodiment 1.

The processing circuit may include a processor 12b and a memory 12c, or may include at least one dedicated hardware 12a instead of these.
When the processing circuit includes the processor 12b and the memory 12c, each function of the start count measuring device 12 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 12 c. The processor 12b reads out and executes the program stored in the memory 12c, thereby realizing each function of the start count measuring device 12.
The processor 12b is also called a CPU (Central Processing Unit), a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The Memory 12c is constituted of, for example, a nonvolatile or volatile semiconductor Memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), a magnetic Disk, a flexible Disk, an optical Disk, a CD (compact Disk), a mini Disk (mini disc), a DVD (Digital Versatile Disk), and the like.
In the case where the processing Circuit includes the dedicated hardware 12a, the processing Circuit is realized by, for example, a single Circuit, a composite Circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.
Each function of the start-up count measuring device 12 can be realized by a processing circuit. Alternatively, the functions of the start count measuring device 12 may be realized by a processing circuit in a lump. The functions of the start count measuring device 12 may be partially implemented by dedicated hardware 12a, and the other parts may be implemented by software or firmware. In this way, the processing circuit realizes each function of the start count measuring device 12 by hardware 12a, software, firmware, or a combination thereof.
