For example, when a certain destination button 13 is pressed, an LED lamp built in the destination button 13 is turned on.
Fig. 2 is a diagram showing an example of the diagnostic device 14 in embodiment 1. Fig. 3 is a view showing a section a-a of fig. 2. The diagnosis 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 to be diagnosed. The portion covered by the cover 15 is shielded from light. Fig. 2 and 3 show an example in which a part of the front surface of the indicator 11, i.e., the LED display 12, is covered with the cover 15. The entire front face of the indicator 11 may also be covered with a cover 15 if the indicator 11 does not have the destination button 13.
The luminance meter 16 is an example of a measuring device that measures luminance of a portion covered with the cover 15. The luminance meter 16 is provided in the cover 15. The luminance meter 16 measures luminance of a portion covered with the cover 15. In the example shown in fig. 2 and 3, the luminance of the LED display 12 covered with 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. Information of the luminance measured by the luminance meter 16 may also be wirelessly transmitted to the main body 18.
The main body 18 includes, for example, a display 19, a storage unit 20, a calculation unit 21, a determination unit 22, and a display control unit 23. The determination unit 22 determines the deterioration state of the indicator 11 based on the luminance measured by the luminance meter 16. The determination unit 22 performs the above determination based on the content stored in the storage unit 20 and the calculation result of the calculation unit 21. The display control unit 23 controls the display 19. The result of the determination by the determination unit 22 is displayed on the display 19 by the display control unit 23.
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 diagnoses the indicator 11 by using the diagnosis device 14 at the time of elevator spot inspection. 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 with the cover 15, light from illumination irradiating the inside of the car 1 does not irradiate the front surface 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 brightness 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 maximum. 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 shows the action of the main body 18. The main body 18 determines whether or not luminance information is acquired from the luminance meter 16 (S103). If it is determined as yes in S103, the calculation unit 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 luminances of the plurality of portions in S104AAnd an evaluation value V related to the brightness deviation of the plurality of portionsDExamples of (3). The calculation unit 21 may calculate only the average value V in S104A. The calculation unit 21 may calculate only the evaluation value V in S104D. The calculation section 21 may calculate the standard deviation as the evaluation value VDThe difference between the maximum value and the minimum value may be calculated as the evaluation value VD. The calculation unit 21 may calculate the average calculated last time in S104Value VAAnd the calculated average value VAThe difference between them.
The determination unit 22 determines the deterioration state of the indicator 11 based on the value calculated by the calculation unit 21. In the present embodiment, the calculation unit 21 calculates the average value V from the calculated valuesAFurther calculating the remaining life Y of the LED display 12ARExamples of (3). In the example shown in the present embodiment, the calculation unit 21 calculates the evaluation value V based on the calculated evaluation value VDFurther calculating the remaining Life YDR。
For example, the storage unit 20 stores the average value V calculated in S104ADeriving the remaining lifetime Y of the part to be diagnosedAR1, in the first step. In the example shown in fig. 2 and 3, the diagnosis target component is the LED display 12. Fig. 5 is a diagram for explaining the 1 st function stored in the storage unit 20. The life curve C shown in FIG. 5 was obtained from experimental data and the likeAAnd registered in the storage unit 20 in advance. For according to the life curve CADeriving the years of life Y of the LED display 12ALThreshold value V ofATHIs preset.
The calculating part 21 is based on the life curve CAAnd the average value V calculated in S104ADetermining the current age Y of the LED display 12A. The calculation unit 21 counts the number of years of life YALMinus the current year of use YACalculating the remaining life Y of the LED displayAR(S105)。
The determination unit 22 determines the remaining life Y calculated by the calculation unit 21ARWhether it is greater than zero (S106). At residual life YARWhen the value is zero or less (no in S106), the determination unit 22 determines that the indicator 11 has deteriorated and needs to be replaced. For example, the determination unit 22 determines that the LED display 12 needs to be replaced or that the modules constituting the LED display 12 need to be replaced. If the determination in S106 is "no", 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 displays that sufficient luminance has not been obtained.
When it is determined as "yes" in S106,based on the evaluation value VDAnd (4) judging. For example, the storage unit 20 stores therein the evaluation value V calculated in S104DDeriving the remaining lifetime Y of the part to be diagnosedDRThe 2 nd function of (1). Fig. 6 is a diagram for explaining the 2 nd function stored in the storage unit 20. The life curve C shown in FIG. 6 was obtained from experimental data and the likeDAnd registered in the storage unit 20 in advance. For according to the life curve CDDeriving the years of life Y of the LED display 12DLThreshold value V ofDTHIs preset.
The calculating part 21 is based on the life curve CDAnd the average value V calculated in S104DDetermining the current age Y of the LED display 12D. The calculation unit 21 counts the number of years of life YDLMinus the current year of use YDCalculating the remaining life Y of the LED displayDR(S108)。
The determination unit 22 determines the remaining life Y calculated by the calculation unit 21DRWhether or not it is larger than zero (S109). At residual life YDRWhen the value is zero or less (no in S109), the determination unit 22 determines that the indicator 11 has deteriorated and needs to be replaced. For example, the determination unit 22 determines that the LED display 12 needs to be replaced or that the modules constituting the LED display 12 need to be replaced. If the determination in S109 is "no", 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, it is displayed on the display 19 that sufficient luminance has not been obtained.
If it is determined as "yes" in S109, the determination unit 22 compares the remaining life Y calculated in S105ARAnd the remaining life Y calculated in S108DR(S110). When it is determined as "yes" in S109, for example, if the remaining life YARSpecific residual life YDRIf short, the display control unit 23 performs the display operation based on the remaining life Y on the display 19ARIs displayed. For example, the display 19 displays "can be used for 2.5 years. ".
Thus, by using the diagnosis device 14 according to the present embodiment, the operator can easily diagnose the indicator 11 without relying on subjectivity.
In the present embodiment, an example in which the number of usable years of the LED display 12 is displayed on the display 19 is described. This is but one example. For example, when the average value V is calculated in S104AIn this case, the determination unit 22 may be configured to calculate the average value V only from the calculated average value VATo determine whether or not the indicator 11 has deteriorated to the extent that replacement of the component is required. For example, when the average value V is calculated in S104AThen, the judgment unit 22 judges the calculated average value VAWhether or not at threshold value VATHThe following. If the average value V isAAt a threshold value VATHThereafter, the determination unit 22 determines that the indicator 11 has deteriorated and needs to be replaced. If the average value V isAGreater than a threshold value VATHThe determination unit 22 does not determine that the indicator 11 has deteriorated and needs to be replaced.
Similarly, when the evaluation value V is calculated in S104DIn this case, the determination unit 22 may calculate the evaluation value V from the calculated evaluation value VDIt is only determined whether or not the indicator 11 has deteriorated to the extent that the parts need to be replaced. For example, when the evaluation value V is calculated in S104DThen, the determination unit 22 determines the calculated evaluation value VDWhether or not at threshold value VDTHThe above. If the evaluation value V isDAt a threshold value VDTHAs described above, the determination unit 22 determines that the indicator 11 has deteriorated and the parts need to be replaced. If the evaluation value V isDLess than threshold VDTHThe determination unit 22 does not determine that the indicator 11 has deteriorated and needs to be replaced.
As another example, the main body 18 may further include a communication unit 24 and an update unit 25. The communication unit 24 communicates with an external information center. The information center acquires information from a plurality of elevator devices. Thereby, the 1 st function and the 2 nd function are learned in the information center. The communication unit 24 acquires 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 addition, when the main body 18 includes the communication unit 24, the 1 st function and the 2 nd function may be stored in the information centerIn (1). For example, in S105, the calculation unit 21 calculates the remaining life YARIn this case, the communication unit 24 acquires the 1 st function from the information center. Thus, the remaining lifetime Y can be always calculated from the latest 1 st functionAR. Similarly, in S108, the calculation unit 21 calculates the remaining life YDRThen, the communication unit 24 acquires the 2 nd function from the information center. Thus, the remaining life Y can be always calculated from the latest 2 nd functionDR。
Further, the 1 st function and the 2 nd function for 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 S105ARIn this case, the communication unit 24 transmits model information to the information center, and acquires the 1 st function corresponding to the model from the information center. Similarly, in S108, the calculation unit 21 calculates the remaining life YDRIn 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 enables the remaining life Y to be calculated with higher accuracyARAnd residual life YDR。

In the example shown in fig. 7, the plurality of destination buttons 13 are covered with a cover 15. In this case, the luminance of the LED lamp built in the destination button 13 is measured by the luminance meter 16. The destination button 13a shown in fig. 7 is one of the destination buttons 13, and is a destination button corresponding to a hall floor. The destination button 13a is pressed the most frequently among the destination buttons 13 provided in the indicator 11. Therefore, the LED lamp built in the destination button 13a is turned on the most frequently in the LED lamp built in the destination button 13. In the example shown in fig. 7, when the cover 15 is disposed at a specific position covering the plurality of destination buttons 13, it is preferable that the LED lamp incorporated in the destination button 13a is disposed at one of a plurality of positions where the luminance meter 16 measures the luminance.
