The diagnostic device 14 is a device used by an operator who performs elevator spot inspection to diagnose the indicators 10 and 11. Hereinafter, an example of diagnosing the pointer 11 by the diagnostic device 14 will be described in detail. The diagnostic device 14 includes, for example, a cover 15, a luminance meter 16, a cable 17, and a main body 18.
The cover 15 is a member for covering a portion of the front surface of the indicator 11 that is a diagnosis target. The portion covered by the cover 15 is shielded from light. Fig. 2 and 3 show an example in which a portion of the front surface of the indicator 11, that is, the LED display 12 is covered with the cover 15. If the pointer 11 is not provided with the destination button 13, the entire front surface of the pointer 11 may also be covered with the cover 15.
The luminance meter 16 is an example of a measuring device that measures the luminance of the portion covered by the cover 15. The luminance meter 16 is provided in the cover 15. The luminance meter 16 is used to measure the luminance of the portion covered by the cover 15. In the example shown in fig. 2 and 3, the luminance of the LED display 12 covered by the cover 15 is measured by the luminance meter 16. Information of the luminance measured by the luminance meter 16 is transmitted to the main body 18 via the cable 17.

The display control unit 23 controls the display 19. The display control unit 23 displays the determination result of the determination unit 22 on the display 19.
Hereinafter, the function of the diagnostic device 14 will be described with reference to fig. 4 to 6. Fig. 4 is a flowchart showing an example of a diagnostic method performed using the diagnostic device 14.
For example, the operator makes a diagnosis of the indicator 11 by the diagnostic device 14 at the time of checking the elevator. First, as shown in fig. 2 and 3, the worker covers the LED display 12 with the cover 15 (S101). When the LED display 12 is covered by the cover 15, light from illumination within the illumination car 1 does not strike the front face of the LED display 12.
Next, the worker measures the luminance of the portion covered by the cover 15, that is, the luminance of the LED display 12, using the luminance meter 16 (S102). For example, when a specific switch provided in the indicator 11 is turned on, the brightness of the LED display 12 is maximized. As another example, when the indicator 11 receives a specific signal from the main body 18, the luminance of the LED display 12 becomes maximum. The luminance measurement by the luminance meter 16 is performed in a state where the luminance of the LED display 12 is maximized. In S102, for example, the luminance of a plurality of portions included in the front surface of the LED display 12 is measured by the luminance meter 16. The luminance information measured by the luminance meter 16 is transmitted to the main body 18.
The processing shown in S103 to S110 of fig. 4 illustrates the operation of the main body 18. In the main body 18, it is determined whether or not luminance information is acquired from the luminance meter 16 (S103). When it is determined to be "yes" in S103, the calculation section 21 calculates a value necessary for diagnosis of the indicator 11 (S104). In the present embodiment, the calculation unit 21 calculates the average value V of the brightness of the plurality of portions in S104 A And an evaluation value V related to the variation of the brightness of the plurality of portions D Is an example of (a). The calculation unit 21 may calculate only the average value V in S104 A . The calculation unit 21 may calculate only the evaluation value V in S104 D . The calculation section 21 may calculate the standard deviation as the evaluation value V D The difference between the maximum value and the minimum value can also be calculated as the evaluation value V D . The calculation unit 21 may calculate the average value V calculated last time in S104 A With the average value V calculated at this time A And (3) a difference.
The determination unit 22 determines the degradation state of the indicator 11 based on the value calculated by the calculation unit 21. In the present embodiment, the calculation unit 21 is shown to calculate the average value V from the calculated average value V A Further calculation of remaining lifetime Y of LED display 12 AR Is an example of (a). In the example shown in the present embodiment, the calculation unit 21 calculates the evaluation value V based on the calculated evaluation value V D Further calculation of remaining lifetime Y DR 。
For example, the storage unit 20 stores an average value V calculated in S104 A Deriving remaining lifetime Y of diagnosis target member AR Is the 1 st function of (2). In the example shown in fig. 2 and 3, the diagnosis target member is the LED display 12. Fig. 5 is a diagram for explaining the 1 st function stored in the storage unit 20. From experimental data and the like, the life curve C shown in FIG. 5 was obtained A And registered in the storage section 20 in advance. For following life curve C A Deriving years of life Y for LED display 12 AL Threshold V of (2) ATH Is preset.
The calculation unit 21 calculates a life curve C A And the average value V calculated in S104 A Determining the current years of use Y of the LED display 12 A . The calculating unit 21 calculates the life time Y AL Minus the current years of use Y A Calculating the remaining life Y of an LED display AR (S105)。
The determination unit 22 determines the remaining life Y calculated by the calculation unit 21 AR Whether or not it is greater than zero (S106). At the remaining life Y AR If zero or less (no in S106), the determination unit 22 determines that the indicator 11 has deteriorated, and the replacement of the component is necessary. For example, the determination unit 22 determines that the LED display 12 needs to be replaced or that a module constituting the LED display 12 needs to be replaced. When the determination is no in S106, the display control unit 23 displays the determination result of the determination unit 22 on the display 19 (S107). For example, if it is determined as no in S106, the display 19 is displayed with a meaning that sufficient brightness is not obtained.
When the determination in S106 is yes, the evaluation value V is based on D Is determined by the (a). For example, the storage unit 20 stores therein an evaluation value V for use in accordance with the evaluation value V calculated in S104 D Deriving remaining lifetime Y of diagnosis target member DR Is the 2 nd function of (2). Fig. 6 is a diagram for explaining the 2 nd function stored in the storage unit 20. From experimental data and the like, the life curve C shown in FIG. 6 was obtained D And registered in the storage section 20 in advance. For following life curve C D Deriving years of life Y for LED display 12 DL Threshold V of (2) DTH Is preset.
The calculation unit 21 calculates a life curve C D And the average value V calculated in S104 D Determining the current years of use Y of the LED display 12 D . The calculating unit 21 calculates the life time Y DL Minus the current years of use Y D Calculating the remaining life Y of an LED display DR (S108)。
The determination unit 22 determines the remaining life Y calculated by the calculation unit 21 DR Whether or not it is greater than zero (S109). At the remaining life Y DR When zero or less (no in S109), the determination unit 22 determines that the pointer 11 is generatedDegradation of the parts that require replacement. For example, the determination unit 22 determines that the LED display 12 needs to be replaced or that a module constituting the LED display 12 needs to be replaced. When the determination is no in S109, the display control unit 23 displays the determination result of the determination unit 22 on the display 19 (S107). For example, if it is determined as no in S109, the display 19 is displayed with a meaning that sufficient brightness is not obtained.
When it is determined to be "yes" in S109, the determination section 22 compares the remaining life Y calculated in S105 AR And the remaining life Y calculated in S108 DR (S110). When the determination in S109 is yes, for example, if the remaining life Y AR Specific residual life Y DR If the time is short, the display control unit 23 performs a process based on the remaining lifetime Y on the display 19 AR Is displayed in the display screen. For example, the display "on the display 19" can also be used for 2.5 years. ".
By using the diagnostic device 14 according to the present embodiment, the operator can easily perform diagnosis of the indicator 11 without relying on subjectivity.
In this embodiment, an example of the number of years of use of the LED display 12 displayed on the display 19 will be described. But this is only an example. For example, when the average value V is calculated in S104 A In this case, the determination unit 22 may determine the average value V based only on the calculated average value V A To determine whether the indicator 11 has degraded requiring replacement of the component. For example, when the average value V is calculated in S104 A In this case, the determination unit 22 determines the calculated average value V A Whether or not it is at threshold V ATH The following is given. If the average value V A At threshold V ATH Hereinafter, the determination unit 22 determines that the indicator 11 is degraded, which requires replacement of the component. If the average value V A Greater than threshold V ATH The determination unit 22 does not determine that the indicator 11 has deteriorated, requiring replacement of the component.
Also, when the evaluation value V is calculated in S104 D In this case, the determination unit 22 may determine the evaluation value V based on the calculated evaluation value V D Only whether the indicator 11 has deteriorated or not requiring replacement of the component is determined. For example, when the evaluation value V is calculated in S104 D Judging at the timeThe determination unit 22 determines the calculated evaluation value V D Whether or not it is at threshold V DTH The above. If the evaluation value V D At threshold V DTH As described above, the determination unit 22 determines that the indicator 11 is degraded, which requires replacement of the component. If the evaluation value V D Less than threshold V DTH The determination unit 22 does not determine that the indicator 11 has deteriorated, requiring replacement of the component.
As another example, the main body 18 may further include a communication unit 24 and an updating unit 25. The communication unit 24 communicates with an external information center. The information center acquires information from a plurality of elevator apparatuses. Thus, the 1 st function and the 2 nd function are learned in the information center. The communication unit 24 obtains the learned 1 st function and 2 nd function from the information center. The updating unit 25 updates the 1 st function and the 2 nd function stored in the storage unit 20 based on the information acquired from the information center by the communication unit 24.
In the case where the main body 18 includes the communication unit 24, the 1 st function and the 2 nd function may be stored in the information center. For example, when the calculation unit 21 calculates the remaining life Y in S105 AR In this case, the communication unit 24 obtains the 1 st function from the information center. Thereby, the remaining lifetime Y can be always calculated from the latest 1 st function AR . Similarly, when the calculation unit 21 calculates the remaining life Y in S108 DR In this case, the communication unit 24 acquires the 2 nd function from the information center. Thereby, the remaining lifetime Y can be always calculated from the latest 2 nd function DR 。
Further, the 1 st function and the 2 nd function of each model of the elevator apparatus may be stored in the information center. In this case, when the calculation section 21 calculates the remaining life Y in S105 AR In this case, the communication unit 24 transmits the model information to the information center, and acquires the 1 st function corresponding to the model from the information center. Also, when the calculation section 21 calculates the remaining life Y in S108 DR In this case, the communication unit 24 transmits the model information to the information center, and acquires the 2 nd function corresponding to the model from the information center. This allows the remaining lifetime Y to be calculated with higher accuracy AR Remaining life Y DR 。
