Description

  The present invention relates to a lighting inspection apparatus and a lighting inspection method for an elevator, and more particularly to an elevator lighting inspection apparatus and a lighting inspection method for inspecting lighting provided in an elevator car.

  Various types of lighting devices are used in elevator cars depending on size and application. In recent years, in addition to fluorescent lamps and incandescent lamps, lighting apparatuses using light emitting diodes as light sources have been widely applied from the viewpoint of energy saving. In general, two or more lighting devices are provided in one car.

  Conventionally, in the case of an elevator, if the lighting device does not turn on due to failure or lifetime, the building administrator who manages the elevator will contact the elevator maintenance company, and the specialist elevator maintenance personnel who received the notification will respond and replace the lighting fixtures. In recent years, however, elevator maintenance companies want to detect malfunctions as soon as possible and reduce the time to recover them. Therefore, in an elevator maintenance company, lighting devices in the elevator car can be remotely connected via telephone lines. There is a case where an illumination monitoring device capable of detecting the abnormality is installed in the elevator in advance. As such a conventional illumination monitoring device, for example, as disclosed in Patent Document 1, it is detected whether the illumination device is normal or abnormal by measuring the illuminance from the illumination device using an optical sensor. In Patent Document 1, an optical sensor is used. In addition to this, an illumination monitoring device that detects whether the illumination device is normal or abnormal has been developed by measuring the current consumption of the illumination device with a current sensor. ing.

The remote monitoring device 2 is connected to the monitoring center 3 through a general telephone line 4 or the like. An illuminating device 8 is provided on the ceiling of the elevator car 6, and the illuminating device 8 is composed of a plurality of luminaires 8a to 8c. Power supply disconnecting means 9 is provided in the power supply line to the lighting device 8 for lighting the lighting fixtures 8a to 8c. The power cut-off means 9 cuts off the power supply to the lighting device 8 in accordance with the in-car lighting on / off command from the elevator control panel 1 for the purpose of energy saving when there is no person in the elevator car 6. Thereby, the lighting fixtures 8a to 8c are simultaneously turned off at the same time.

  Moreover, the optical sensors 7a-7c are provided for each lighting fixture 8a-8c. Outputs from the optical sensors 7 a to 7 c are input to the illumination monitoring device 5. The illumination monitoring device 5 generates in-car illumination information indicating whether the illumination fixtures 8a to 8c of the illumination device 8 are normally lit based on the optical sensor inputs from the optical sensors 7a to 7c, and the elevator control panel 1 Output to. The microprocessor 1a in the elevator control panel 1 is based on the relationship between the in-car lighting on / off command to the power-off means 9 output from the elevator control panel 1 and the in-car lighting information from the lighting monitoring device 5. The lighting device 8 in the car 6 is monitored for normal lighting, and the result is notified to the monitoring center 3 via the remote monitoring device 2 and the general telephone line 4.

For this reason, it is strictly designed to optimize the number of light sensors installed and the position of the light sensor depending on the type of lighting fixture and the type of lighting device, or the light incident on the light sensor is limited to the light from the lighting fixture. Therefore, it was necessary to prepare a light shielding cover for adjusting the incident light. In particular, elevator ceiling lighting devices have a variety of designs for each customer and each building. Therefore, in order to avoid the above-mentioned problems, it takes a lot of time to install the optical sensor. It was.

Embodiment 1 FIG.
FIG. 2 is a configuration diagram showing the configuration of an elevator illumination inspection apparatus (hereinafter simply referred to as an illumination inspection apparatus) according to Embodiment 1 of the present invention and the entire monitoring system in which it is installed. The illumination inspection device according to the first embodiment includes an illumination inspection unit 11, an imaging device 12, and a power-off unit 10, which will be described later, and an illumination inspection process based on image data captured by the imaging device 12.

  In FIG. 2, reference numeral 1 denotes an elevator control panel that controls the overall operation of the elevator, and includes a microprocessor 1a that performs various controls while transmitting signals to and from various devices. The elevator control panel 1 can notify the monitoring center 3 of the elevator maintenance company via the remote monitoring device 2 of the operation status of the elevator and whether or not an abnormality has occurred. The remote monitoring device 2 is connected to the monitoring center 3 via a communication means such as a general telephone line 4 or the Internet. Moreover, the illuminating device 8 is installed in the ceiling of the elevator car 6, an inner wall, or a floor, and the illuminating device 8 is comprised by several lighting fixtures 8a-8c.

  Further, as shown in FIG. 2, the car 6 is provided with a lighting inspection means 11, which can transmit signals to and from the elevator control panel 1 and also has a power-off means. 10 outputs a lighting fixture on / off control command. In addition, an imaging device 12 is provided in the car 6 as imaging means that can take an image of the car 6. The imaging device 12 is composed of a digital camera, a digital video camera, or the like, and photographs the inside of the car 6. Note that image data obtained by photographing with the imaging device 12 is input to the illumination checking means 11. Moreover, the power-supply-cutting means 10 is provided in the electric power supply line to the illuminating device 8 for lighting each lighting fixture 8a-8c. Unlike the power-off means 9 in FIG. 1, the power-off means 10 individually connects power supply lines to each of the lighting fixtures 8 a to 8 c of the lighting device 8. Therefore, the power cutting means 10 can individually switch between power supply / power cutoff for each of the lighting fixtures 8a to 8c. The lighting check means 11 has a passenger detection sensor for detecting whether or not a person is present in the car 6. If there is no person in the car 6, the lighting check means 11 is used for the purpose of energy saving. When the appliances 8 a to 8 c are turned off and a person has entered the car 6, a car lighting on / off control command for turning on the lighting fixtures 8 a to 8 c is sent to the power-off means 10. Output. In addition, the lighting inspection unit 11 outputs an on / off control command for the lighting fixtures to the power-off unit 10 when checking the individual lighting fixtures 8 a to 8 c.

  FIG. 3 is a block diagram showing a configuration in the illumination checking means 11. As shown in FIG. 3, the illumination checking means 11 includes an arithmetic processing unit 11a composed of a microprocessor and the like for performing processing of the entire lighting checking means 11 such as an inspection procedure operation process and a measurement result determination process, and an imaging process. An image processing unit 11b that performs image processing of image data from the apparatus 12 and converts the data into data that can be calculated by the calculation processing unit 11a, a communication control unit 11c that performs signal transmission between the elevator control panel 1, and a power source It comprises an I / O control unit 11d that outputs on / off control commands for the lighting fixtures 8a to 8c to the cutting means 10, and a storage unit 11e that can store image data, various parameter data necessary for illumination inspection, and the like. . Further, the communication control unit 11c is configured to be able to connect a function setting unit 13 constituted by a personal computer or the like, and can transmit signals to and from the function setting unit 13. By operating the function setting means 13, a specialized elevator maintenance worker of an elevator maintenance company can set and change various parameter data necessary for lighting inspection. The function setting means 13 may be always connected, but it may be configured by a portable computer such as a portable notebook computer and connected by a cable or the like as necessary.

  Next, the operation of the illumination inspection process according to the first embodiment will be described with reference to FIGS. 2 and 3 and FIGS. 4 and 5 which are operation flowcharts. FIG. 4 shows a schematic procedure of the illumination inspection process in the car in the microprocessor 1a in the elevator control panel 1. FIG. 5 shows a schematic procedure of the illumination inspection process in the car in the illumination inspection means 11.

  First, the lighting inspection process in the car in the microprocessor 1a in the elevator control panel 1 will be described with reference to FIGS. In the first embodiment, the timing of lighting inspection that is set in advance for performing the lighting inspection (for example, the timing when the elevator is not used for a certain period of time and shifts to a sleep state in order to save energy), and The lighting inspection process is started only when the elevator user (passenger) is not in the car 6. Therefore, the microprocessor 1a first determines in step S1 whether or not the current state of the elevator is at a lighting inspection possible timing and the elevator user (passenger) is not in the car 6. judge. As a result of the determination, if not, the lighting is not inspected and the process is terminated as it is. On the other hand, as a result of the determination, if so, the process proceeds to step S <b> 2, and an illumination inspection command signal for starting the illumination inspection is transmitted to the illumination inspection means 11. As a result, the lighting inspection unit 11 performs the lighting inspection, and the lighting inspection result (including information on normality and abnormality) is returned. Therefore, the lighting inspection result is received in step S3, and the lighting inspection is performed in step S4. The result is stored in a storage device (not shown) connected to the microprocessor 1a. Next, in step S5, the microprocessor 1a determines whether or not the illumination inspection result is normal. If the illumination inspection result is normal, the microprocessor 1a ends the processing as it is. On the other hand, if the illumination check result is not normal, in step S6, the microprocessor 1a notifies the monitoring center 3 via the remote monitoring device 2 to notify the monitoring center 3 that the lighting device 8 is abnormal. Anomaly information is reported.

  Next, with reference to FIGS. 2, 3, and 5, the lighting check process in the car in the lighting check means 11 will be described. The process of FIG. 5 is performed in the illumination inspection means 11 between step S2 and step S3 of FIG.

  As shown in FIG. 5, first, in step S11, the illumination inspection means 11 sends the illumination inspection command output from the microprocessor 1a of the elevator control panel 1 in the process of step S2 of FIG. 2 described above to the communication control unit 11c. Is received, the lighting check process is started by the arithmetic processing unit 11a. First, in step S12, the arithmetic processing unit 11a outputs an on / off control command to the power-off means 10 via the I / O control unit 11d. The on / off control command instructs to turn on only one preset lighting fixture among the lighting fixtures 8a to 8c and turn off the other lighting fixtures. Here, in order to make the explanation easy to understand, it is assumed that the on / off control command instructs to turn on only the lighting fixture 8a and turn off the lighting fixtures 8b and 8c. Thereby, only the lighting fixture 8a is turned on, and the lighting fixtures 8b and 8c are turned off. In this state, in step S13, the imaging device 12 installed in the car 6 is used to photograph the inside of the car 6, and the image processing unit 11b captures image data obtained by the photographing. In step S14, the image processing unit 11b detects the brightness of the image data. Specifically, luminance data (brightness data) is extracted from the image data and converted into a grayscale image. Next, in step S15, the arithmetic processing unit 11a determines whether or not the current process is the first process. If the first process, the process proceeds to step S16, and the grayscale image created in step S14 is the first time. The data is stored in the storage unit 11e. Since the initial data is preferably generated from image data taken when the lighting fixtures 8a to 8c are in the best condition, it can be generated when the lighting fixtures 8a to 8c are not deteriorated. For example, when the elevator car 6 is installed or at the initial stage of start of use immediately after installation, the inside of the car 6 is photographed.

  On the other hand, if it is determined in step S15 that it is the second or later lighting inspection process, the process proceeds to step S17, and the arithmetic processing unit 11a stores the initial data (grayscale image) stored in the storage unit 11e. Are compared with the grayscale image generated from the image data obtained by the current shooting, and difference data (amount of change) is extracted. Next, in step S18, the arithmetic processing unit 11a compares the difference data with the off failure determination value (first threshold value) stored in advance in the storage unit 11e, and the difference data becomes the off failure determination value ( If it is greater than the first threshold value, it is determined that the lighting fixture 8a designated as “lighted” in step S12 is not lit and has failed (hereinafter referred to as “off failure”), and the process proceeds to step S19. Then, the off failure data related to the lighting fixture 8a is created, and the process proceeds to Step 20. On the other hand, if the difference data is less than the off failure determination value (first threshold value), the arithmetic processing unit 11a determines that the lighting fixture 8a is normal, skips the process of step S19, and proceeds to step S20. . Further, in step S20, the arithmetic processing unit 11a compares the difference data with the illuminance decrease determination value (second threshold value) stored in advance in the storage unit 11e, and the difference data indicates the illuminance decrease determination value (first value). If it is greater than the threshold value (2), it is determined in step S12 that the illuminance of the lighting fixture 8a designated as “lighting” has deteriorated, and in step S21, illuminance deterioration data relating to the lighting fixture 8a is created, and step S22. Proceed to Next, if the difference data is less than the illuminance decrease determination value (second threshold value), the arithmetic processing unit 11a skips the process of step S21 and proceeds to step S22. In step S22, the arithmetic processing unit 11a determines whether or not the processing of steps S12 to S21 has been completed for all of the lighting fixtures 8a to 8c. If not, the processing returns to step S12. Only the lighting fixture 8b is turned on, the lighting fixtures 8a and 8c are turned off, and the inspection process of steps S12 to S21 is similarly performed. When the inspection process ends, this time, only the lighting fixture 8c is turned on, the lighting fixtures 8a and 8b are turned off, and the inspection processing of steps S12 to S21 is similarly performed. In this way, the processing of steps S12 to S21 is repeated as many times as the number of lighting fixtures 8a to 8c, and individual inspections are sequentially performed for all the lighting fixtures 8a to 8c. In addition, the number of the lighting fixtures 8a to 8c and the order of inspection are set in advance in the storage unit 11e as parameter data. If it is determined in step S22 that the calculation processing unit 11a has completed the determination processing for all of the luminaires, in step S23, the calculation processing unit 11a passes the I / O control unit 11d to the power-off unit 10. The on / off control command is output, and all the lighting fixtures 8a to 8c are turned on. In step S24, the result of the lighting check for each of the lighting fixtures 8a to 8c is returned as the lighting check result to the microprocessor 1a of the elevator control panel 1 via the communication control unit 11c. The lighting inspection result thus returned is received by the microprocessor 1a of the elevator control panel 1 in step S3 in FIG. By performing the illumination check process according to the above procedure, it becomes possible to detect an off failure or illuminance deterioration for each of the lighting fixtures 8a to 8c.

  Further, in the lighting check process, the elevator control panel 1 counts the accumulated time that the lighting device 8 is lit from the elevator operation time, and when the lighting check command is transmitted or before that, the lighting check is performed. The accumulated lighting time of the lighting device 8 may be transmitted to the means 11. When the illumination checking means 11 performs the process of determining the decrease in illuminance in step S20 of FIG. 5, the accumulated lighting time of the received illuminating device 8 and the luminaires 8a to 8c previously set as parameter data in the storage unit 11e. An illuminance decrease determination value (second threshold value) is determined from the illuminance decrease scheduled value with respect to the accumulated lighting time, and thereby illuminance deterioration data is created. In addition, the illuminance reduction scheduled value is created in advance from average data such as a life test of a lighting fixture, and is stored in the storage unit 11e. By performing the processing procedure as described above, it is possible to detect illuminance deterioration in consideration of aging deterioration associated with long-term use. In addition, by capturing the measurement results in time series, and gradually detecting the difference between the predicted decrease in illuminance and the measurement results, if the amount of change exceeds a certain value, monitoring By notifying the center 3, it becomes possible to grasp the early deterioration of the lighting fixtures 8a to 8c, and the lighting fixtures 8a to 8c can be inspected or replaced by preventive maintenance before the lighting is cut off. It becomes possible.

  In addition, in the process of comparing the image data in the image processing unit 11b and the calculation processing unit 11a of the illumination inspection process and extracting the difference data, and determining the off failure or the illuminance deterioration, any image in the image data If the range can be set as the processing target range (hereinafter referred to as the detection target range), the wall color and the material are affected by the elevator car 6 having various designs according to the customer's request. Comparison can be performed only in a few places. For example, if the surface of a button on the operation panel in the car 6 is set as a detection target range, a uniform illuminance can be applied to any elevator car design as long as the button type is the same. Comparison is possible. Therefore, in the first embodiment, the setting of the detection target range can be adjusted by the elevator maintenance staff when the car 6 and the lighting inspection means 11 are installed using the function setting means 13. Keep it. The set contents are stored and stored in the storage unit 11e. Further, even after that, the setting contents stored in the storage unit 11e can be arbitrarily changed by the elevator maintenance staff by connecting the function setting means 13 to the lighting inspection means 11. ing.

  Further, as the imaging device 12 in FIG. 2, it is possible to share a security camera installed in the car 6 and divert the video signal from the security camera. This makes it possible to obtain image data in the car without newly providing an imaging device.

  As described above, the illumination inspection apparatus according to Embodiment 1 of the present invention is an apparatus for inspecting the illumination apparatus 8 in the elevator car 6 constituted by the plurality of illumination fixtures 8a to 8c. Each of the lighting fixtures 8a to 8c is provided in the car 6 with the power-off means 10 for switching the power supply and the power cutoff individually, and in the car 6 under the illumination light by the lighting fixtures 8a to 8c. An image pickup device 12 as an image pickup means for photographing the image and outputting the image data, and an image processing section as a detection means for detecting the brightness (luminance) of the image data by analyzing the image data from the image pickup device 12 The lighting inspection means 11 having 11b, and switching the power-off means 10 to turn on only one of the lighting fixtures 8a to 8c and turn off the other lighting fixtures 8a to 8c. In this state, photographing is performed by the imaging device 12, and the lighting state of each lighting fixture 8a to 8c is measured based on the brightness (luminance) of the image data, and each lighting fixture 8a to 8c is measured. Detecting normal / failure every time. With this configuration, in the illumination inspection apparatus according to Embodiment 1 of the present invention, image data from the imaging device 12 such as a digital camera is subjected to image analysis by the image processing unit 11b, so that the image data can be analyzed at an arbitrary timing. The brightness in the elevator car 6 can be measured and detected. At this time, for each of the lighting fixtures 8a to 8c, the power supply disconnecting means 10 that can individually cut off the power supply is provided, and the lighting fixtures 8a to 8c are captured from the timing at which the lighting inspection process can be performed based on the usage status of the elevator. The power supply is controlled to be cut off so that only one of them is turned on, and the brightness (luminance data) in the car 6 is measured by the image processing unit 11b from the image data captured by the imaging device 12. . By repeating this for all the lighting fixtures while sequentially switching the power supply of the lighting fixtures 8a to 8c, it is possible to detect whether or not the lighting fixtures 8a to 8c are correctly lit (off failure detection). In addition, since it is determined from the image data, it is not necessary to optimize and install according to the type of lighting fixture or the type of lighting device as in the case of conventional optical sensors. It is unnecessary.

  In addition, the lighting inspection apparatus according to Embodiment 1 of the present invention includes a storage unit 11e serving as storage means for storing brightness data of image data captured by the imaging apparatus 12 as initial data in the early stage of use of the elevator, Comparing the initial data and brightness data detected from the current image data, and based on the amount of change, further includes an arithmetic processing unit 11a as a determination unit that determines the deterioration status of the lighting fixtures 8a to 8c. I have. In general, the illuminance of a luminaire decreases gradually due to deterioration over time, but the brightness data measured at the beginning of use is used as the initial data so that the degree of illuminance can be measured and detected. It is possible to calculate how much the illuminance of the lighting fixture has decreased by storing it in the storage unit 11e and comparing it with the measured brightness data. At this time, from the relationship of the amount of decrease in illuminance with the cumulative lighting time of the luminaires 8a to 8c predicted in advance, it is determined whether the illuminance decrease amount due to the measurement result is appropriate as the luminaires 8a to 8c. If the illuminance is greatly reduced by a certain amount or more than the value, it can be determined that the lighting fixtures 8a to 8c are abnormal, and the lighting fixture can be inspected or replaced by preventive maintenance before the lighting is cut off. It becomes possible.

  In addition, the illumination inspection apparatus according to Embodiment 1 of the present invention further includes a function setting unit 13 as a detection condition setting unit that designates an arbitrary image range of image data and sets it as a detection target range in the detection unit. I have. In general, elevator cars have various designs according to customer requirements. For this reason, it becomes difficult to measure and detect the illuminance of the lighting fixtures 8a to 8c from the image data depending on the arrangement and type of the lighting fixtures 8a to 8c or the color and material of the inner wall of the car 6. Therefore, in the present embodiment, the function setting unit 13 as the detection condition setting unit is further provided, and a partial range of the image data or a plurality of image ranges in the image data is arbitrarily set as the detection target range, and the brightness is set. By measuring and detecting the brightness, the brightness can be measured and detected with the optimum measurement location as the detection target range.

  Moreover, the lighting inspection apparatus according to Embodiment 1 of the present invention shares a security camera installed in the car 6 as the imaging device 12, and uses a video signal from the security camera as image data. It is also possible to do. In recent years, an elevator car 6 is often provided with a security camera for the purpose of crime prevention. Therefore, in the present invention, the security camera is shared as the imaging device 12, and the image data from the security camera is subjected to image analysis by the arithmetic processing unit 11a in the lighting inspection means 11, so that the image data can be analyzed at any timing. The brightness in the elevator car 6 can be measured and detected. Thus, the elevator lighting inspection apparatus according to the present invention can be configured without newly installing a digital camera or the like as the imaging apparatus 12.
