For example, the information center device 16 is provided in a maintenance company of an elevator. The information center device 16 is provided so as to be able to grasp the state of the elevator based on information from the monitoring device 14 and the determination device 15.
Next, the monitoring device 14 and the determination device 15 will be described with reference to fig. 2.
Fig. 2 is a block diagram of a monitoring device and a determination device for an elevator in embodiment 1.
As shown in fig. 2, the monitoring device 14 includes an operation mode setting unit 14a and an image information acquiring unit 14b.
The operation mode setting unit 14a sets an operation mode of the elevator. The image information acquisition unit 14b determines whether the operation mode setting unit 14a sets the operation mode of the elevator to an image acquisition mode for detecting contamination of the security camera 12.
When the operation mode setting unit 14a sets the operation mode of the elevator to the image acquisition mode at the time of remote spot inspection, the image information acquisition unit 14b determines whether or not an image information acquisition condition for acquiring information for detecting an image for preventing contamination of the camera 12 is satisfied.
For example, when no person is present in the car 6, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied. For example, when no person is present in the car 6 when the lighting device 10 of the car 6 is turned on, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied. For example, when the illumination device 10 of the car 6 is turned on and no person is present in the car 6 when the door of the car 6 is closed, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied. For example, when the door of the car 6 is closed and the lighting device 10 of the car 6 is turned on and no person is present in the car 6 when the car 6 is stopped, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied. For example, when the door of the car 6 is closed and the lighting device 10 of the car 6 is turned on and no person is present in the car 6 when the car 6 stops at a predetermined specific floor, the image information acquisition unit 14b determines that the image information acquisition condition is satisfied.
When the image information acquisition condition is satisfied, the image information acquisition unit 14b acquires information of the image of the security camera 12. The image information acquiring unit 14b transmits the information of the image to the determination device 15.
As shown in fig. 2, the determination device 15 includes a determination unit 15a.
The determination unit 15a determines the contamination of the security camera 12 based on the information of the image from the monitoring device 14.
For example, the determination unit 15a determines the contamination situation of the security camera 12 based on, for example, the comparison result between the information of the reference image of the security camera 12 when no person is present in the car 6 and the information of the image acquired by the monitoring device 14 when the operation mode of the elevator is the image acquisition mode, in a state where the security camera 12 is not contaminated and the image information acquisition condition is satisfied. At this time, the determination unit 15a digitizes the image information and then determines that contamination of the camera 12 is prevented.
When the monitoring device 14 acquires information of an image of the security camera 12 when no person is inside the car 6 when the operation mode of the elevator is the image acquisition mode, the determination unit 15a determines a failure of the security camera 12 based on the information of the image. For example, when most of the information of the image is information indicating black, the determination unit 15a determines to prevent the camera 12 from malfunctioning.
Next, an outline of the operation of the monitoring device 14 will be described with reference to fig. 3.
Fig. 3 is a flowchart for explaining an outline of the operation of the elevator monitoring device in embodiment 1.
In step 1, the monitoring device 14 determines whether or not the current time is a period in which the operation mode of the elevator is set to the image acquisition mode.
In the case where the current time in step S1 is not a time period in which the operation mode of the elevator is set to the image acquisition mode, the monitoring device 14 performs the operation in step S1. In the case where the current time in step S1 is a time period in which the operation mode of the elevator is set to the image acquisition mode, the monitoring device 14 performs the operation of step S2.
In step S2, the monitoring device 14 sets the operation mode of the elevator to the image acquisition mode. In setting the image acquisition mode, the monitoring device 14 may output a promotion instruction to the control device 13 to promote establishment of the image information acquisition condition. For example, in the setting of the image acquisition mode, when the image information acquisition condition described above includes the lighting device 10 of the car 6 being turned on, the monitoring device 14 determines whether the lighting device 10 of the car 6 is turned on or off. When it is determined that the lighting device 10 of the car 6 is turned off in this determination, the monitoring device 14 outputs a promotion instruction for turning on the lighting device 10 of the car 6 to the control device 13. For example, in the setting of the image acquisition mode, when the image information acquisition condition described above includes the door of the car 6 being closed, the monitoring device 14 determines whether the door of the car 6 is closed or opened. When it is determined that the door of the car 6 is open in this determination, the monitoring device 14 outputs a promotion instruction for closing the door of the car 6 to the control device 13. For example, in the setting of the image acquisition mode, when the image information acquisition condition includes stopping at a predetermined specific floor, the monitoring device 14 determines whether or not the car 6 is stopped at the predetermined specific floor. When it is determined that the car 6 has not stopped at the predetermined specific floor in this determination, the monitoring device 14 outputs a promotion command for moving the car 6 to the predetermined specific floor to the control device 13. Then, the monitoring device 14 performs the operation of step S3. In step S3, the monitoring device 14 determines whether or not the image information acquisition condition is satisfied.
When the image information acquisition condition is not satisfied in step S3, the monitoring device 14 performs the operation of step S1. When the time period for setting to the image acquisition mode in step 1 has elapsed while the image information acquisition condition is not satisfied, the image acquisition mode setting operation may be temporarily suspended, for example, the image acquisition mode setting operation may be restarted in the same time period on the next day. In the case where the image information acquisition condition is not satisfied in step S3, the monitoring device 14 may output a promotion instruction to the control device 13 to promote satisfaction of the image information acquisition condition. When the image information acquisition condition is satisfied in step S3, the monitoring device 14 performs the operation of step S4.
In step S4, the monitoring device 14 acquires information about the image of the security camera 12. Then, the monitoring device 14 performs the operation of step S5. In step S5, the monitoring device 14 transmits information of the image to the determination device 15. Then, the monitoring device 14 ends the operation.
Next, an outline of the operation of the determination device 15 will be described with reference to fig. 4.
Fig. 4 is a flowchart for explaining an outline of the operation of the determination device of the elevator in embodiment 1.
In step S11, the determination device 15 determines whether or not information of an image from the monitoring device 14 is received. When the image from the monitoring device 14 is not received in step S11, the determination device 15 performs the operation of step S11. When the image from the monitoring device 14 is received in step S11, the determination device 15 performs the operation of step S12.
In step S12, the determination device 15 determines whether or not the security camera 12 has failed based on the information of the image.
In the case where the camera 12 is prevented from malfunctioning in step S12, the determination device 15 performs the operation of step S13. In step S13, the determination means 15 determines whether the security camera 12 is contaminated or not based on the information of the image.
In the case where the camera 12 is prevented from being contaminated in step S13, the determination device 15 performs the operation of step S14. In step S14, the determination device 15 transmits information indicating that the camera 12 is prevented from being contaminated and has not failed to the information center device 16. Then, the determination device 15 ends the operation.
In the case where the camera 12 is prevented from malfunctioning in step S12, the determination device 15 performs the operation of step S15. In step S15, the determination device 15 transmits information indicating that the camera 12 is prevented from malfunctioning to the information center device 16. Then, the determination device 15 ends the operation.
In the case where the camera 12 is prevented from being contaminated in step S13, the determination device 15 performs the operation of step S16. In step S16, the determination device 15 transmits information indicating that the camera 12 is protected from contamination to the information center device 16. Then, the determination device 15 ends the operation.
Next, an outline of the operation of the information center device 16 will be described with reference to fig. 5.
Fig. 5 is a flowchart for explaining an outline of the operation of the information center device of the elevator in embodiment 1.
In step S21, the information center apparatus 16 determines whether or not information from the determination apparatus 15 is received. If the information from the determination device 15 is not received in step S21, the information center device 16 performs the operation of step S21. When the information from the determination device 15 is received in step S21, the information center device 16 performs the operation of step S22.
In step S22, the information center apparatus 16 determines whether or not the security camera 12 has failed based on the information.
In the case where the camera 12 is prevented from malfunctioning in step S22, the determination device 15 performs the operation of step S23. In step S23, the information center apparatus 16 determines whether the security camera 12 is contaminated or not based on the information.
In the case where the camera 12 is prevented from being contaminated in step S23, the information center apparatus 16 performs the operation of step S24. In step S24, the information center device 16 registers information indicating that the camera 12 is prevented from being contaminated and from malfunctioning as the maintenance history of the elevator. Then, the information center device 16 ends the operation.
In the case where the camera 12 is prevented from malfunctioning in step S22, the information center apparatus 16 performs the operation of step S25. In step S25, the information center device 16 registers information indicating that the security camera 12 has failed as the maintenance history of the elevator. At this time, the information center device 16 transmits information indicating that the security camera 12 has failed to a portable terminal of a maintainer located near the building where the elevator is installed. Then, the information center device 16 ends the operation.
In the case where the camera 12 is prevented from being contaminated in step S23, the information center apparatus 16 performs the operation of step S26. In step S26, the information center apparatus 16 registers information indicating that the security camera 12 is contaminated as the maintenance history of the elevator. At this time, the information center device 16 transmits information indicating that the security camera 12 is contaminated to a portable terminal of a maintainer located near the building where the elevator is installed. Then, the information center device 16 ends the operation.
According to embodiment 1 described above, when the operation mode of the elevator is the image acquisition mode, the image of the security camera 12 is acquired when no person is present in the car 6. Therefore, contamination of the camera 12 can be detected and prevented while ensuring privacy. Further, it is sufficient to determine whether or not the inside of the car 6 is unmanned based on the detection result of the scale device 11. Further, it may be determined that no person is present in the car 6 when there is no car call.
For example, the monitoring device 14 acquires information of the image of the security camera 12 when no person is present in the car 6 when the lighting device 10 is turned on. Therefore, information for preventing the image of the camera 12 can be acquired in a state where the interior of the car 6 is brighter. As a result, contamination of the security camera 12 can be detected more reliably.
For example, when the door of the car 6 is closed, the monitoring device 14 acquires information of the image of the security camera 12 when the lighting device 10 is turned on and the inside of the car 6 is unmanned. Therefore, the conditions for acquiring the image information of the security camera 12 can be matched, and the image information of the security camera 12 can be acquired in a state where the interior of the car 6 is brighter. As a result, contamination of the security camera 12 can be detected more reliably.
For example, when the car 6 is stopped, the monitoring device 14 acquires information of an image of the security camera 12 when the door of the car 6 is closed, the lighting device 10 is turned on, and the inside of the car 6 is unmanned. Therefore, it is possible to prevent light from entering from the security window provided in the car 6 from varying, to make the conditions uniform when the information of the image of the security camera 12 is acquired, and to acquire the information of the image of the security camera 12 when the inside of the car 6 is in a brighter state. As a result, contamination of the security camera 12 can be detected more reliably.
For example, when the car 6 is stopped at a predetermined specific floor, the monitoring device 14 acquires information on the image of the security camera 12 when the door of the car 6 is closed, the lighting device 10 is turned on, and no person is present in the car 6. Therefore, it is possible to prevent light from entering from the security window provided in the car 6 from varying, to make the conditions uniform when the information of the image of the security camera 12 is acquired, and to acquire the information of the image of the security camera 12 when the inside of the car 6 is in a brighter state. As a result, contamination of the security camera 12 can be detected more reliably.
The determination device 15 determines the contamination of the security camera 12 based on the information of the image from the security camera 12. Therefore, contamination of the camera 12 can be detected and prevented while ensuring privacy.
Specifically, the determination device 15 determines the contamination of the security camera 12 based on the result of comparison between the information of the reference image of the security camera 12 when the security camera 12 is not contaminated and no person is present in the car 6 and the information of the image acquired by the monitoring device 14 when the operation mode of the elevator is the image acquisition mode. Therefore, contamination of the security camera 12 can be detected more reliably.
The determination device 15 also determines that contamination of the camera 12 is prevented after digitizing the image information. Therefore, contamination of the security camera 12 can be quantitatively detected while ensuring privacy reliably.
Further, the determination means 15 determines a malfunction of the security camera 12 based on information of the image from the security camera 12. Thus, contamination and malfunction of the camera 12 can be discriminated and prevented for detection.
The determination device 15 transmits information of the determination result of the state of the security camera 12 to the outside. Therefore, the maintenance person or the like can be appropriately informed of the state of the security camera 12. As a result, an appropriate maintenance work can be performed on the security camera 12.
The function of the determination device 15 may be provided adjacent to the monitoring device 14. The function of the determination device 15 may be provided in the information center device 16. In this case, the contamination of the camera 12 can be detected and prevented while ensuring privacy.
Further, the determination device 15 may directly transmit information of the determination result of the state of the security camera 12 to the portable terminal of the maintainer. In this case, the security camera 12 can be appropriately maintained.
The monitoring device 14, the determination device 15, and the elevator system according to embodiment 1 may be applied to an elevator without the machine room 2. In this case, the contamination of the camera 12 can be detected and prevented while ensuring the privacy of the user.
Next, an example of the monitoring device 14 will be described with reference to fig. 6.
Fig. 6 is a hardware configuration diagram of the elevator monitoring device in embodiment 1.
The functions of the monitoring device 14 can be realized by a processing circuit. For example, the processing circuit has at least 1 processor 17a and at least 1 memory 17b. For example, the processing circuitry has at least 1 dedicated hardware 18.
In the case of a processing circuit having at least 1 processor 17a and at least 1 memory 17b, the functions of the monitoring device 14 are implemented by software, firmware or a combination of software and firmware. At least one of the software and the firmware is described as a program. At least one of the software and firmware is stored in at least 1 memory 17b. At least 1 processor 17a realizes each function of the monitoring device 14 by reading out and executing programs stored in at least 1 memory 17b. At least 1 processor 17a is also called central processing unit, arithmetic unit, microprocessor, microcomputer, DSP. For example, at least 1 memory 17b is a nonvolatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, etc., a magnetic disk, a floppy disk, an optical disk, a high-density disk, a mini disk, a DVD, etc.
In the case of a processing circuit having at least 1 dedicated hardware 18, the processing circuit is implemented, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the monitoring device 14 is realized by a processing circuit. For example, the functions of the monitoring device 14 are unified by a processing circuit.
With respect to each function of the monitoring device 14, one part may be realized by dedicated hardware 18, and the other part may be realized by software or firmware. For example, the functions of the operation mode setting unit 14a may be realized by a processing circuit that is dedicated hardware 18, and the functions other than the functions of the operation mode setting unit 14a may be realized by at least 1 processor 17a reading and executing a program stored in at least 1 memory 17b.
Thus, the processing circuitry implements the functions of the monitoring device 14 through hardware 18, software, firmware, or a combination thereof.
Although not shown, the functions of the control device 13 may be realized by the same processing circuit as that for realizing the functions of the monitoring device 14. The respective functions of the determination device 15 may be realized by the same processing circuit as that for realizing the respective functions of the monitoring device 14. The functions of the information center device 16 may be realized by the same processing circuit as the processing circuit that realizes the functions of the monitoring device 14.
