BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. FIG. 1 is a configuration diagram of an elevator control device according to an embodiment of the present invention. The car 11 for raising and lowering the passenger is provided with a pressure control device 12 for changing the air pressure in the car 11 to be raised and lowered in accordance with the state of lifting. The car air pressure in the car 11 is measured by the car air pressure measuring means 13 installed in the car 11 and is input to the air pressure controller 14 of the air pressure control device 12. The air pressure controller 14 outputs a drive command to the intake blower driving means 16A or the exhaust blower driving means 16B so that the car internal pressure changes according to the air pressure pattern (atmospheric pressure target value) of the air pressure pattern generating means 15.
[0015]
That is, the intake blower driving means 16A draws air into the car 11 to drive the intake blower 17A for raising the air pressure in the car 11, and the exhaust blower driving means 16B exhausts the air in the car 11. The exhaust blower 17B for lowering the air pressure in the car 11 is driven.
[0016]
Further, an abnormality monitoring device 18 for monitoring an abnormal state of the air pressure control by the air pressure control device 12 is provided. The abnormality monitoring device 18 detects an abnormality in the air pressure state in the car 11 based on the car internal pressure measured by the car internal pressure measuring means 13 and the car internal and external pressure difference measured by the car internal and external pressure difference measuring means 19. An atmospheric pressure condition abnormality monitoring means 20 for monitoring, an atmospheric pressure pattern abnormality monitoring means 21 for monitoring an abnormality of the atmospheric pressure pattern of the atmospheric pressure pattern generating means 15 of the atmospheric pressure control device 12, and an abnormality of the atmospheric pressure control operation of the air pressure controller 14 of the atmospheric pressure control device 12. And a pressure controller abnormality monitoring means 22 for monitoring the pressure. As described above, since the abnormality monitoring device 18 that detects an abnormal operation of the air pressure control device 12 is provided separately from the air pressure control device 12, the abnormality of the air pressure control device 12 can be appropriately monitored.
[0017]
The abnormality information detected by the atmospheric pressure state abnormality monitoring means 20, the atmospheric pressure pattern abnormality monitoring means 21, and the atmospheric pressure controller abnormality monitoring means 22 of the abnormality monitoring device 18 is input to and stored in the abnormal state storage unit 23, and the elevator controller 24 Is also entered.
[0018]
In the normal state, the elevator controller 24 controls the traveling speed of the car 11 according to the traveling speed pattern of the car 11 from the speed pattern generating means 25. On the other hand, when the elevator controller 24 receives the pressure control abnormality information from the abnormality monitoring device 18, the elevator controller 24 outputs a pressure control stop command to the pressure controller 14 of the pressure control device 12, and outputs a pressure control abnormal command to the speed pattern generation means 25. A command signal for generating a time traveling speed pattern is output. Thereby, the air pressure control by the air pressure control device 12 is stopped, and the elevator controller 24 shifts the traveling speed pattern of the car 11 to the traveling speed pattern for abnormal pressure control.
[0019]
When the abnormality monitoring device 18 detects an abnormal state of the air pressure control by the air pressure control device 12, the elevator controller 24 outputs a message to the message display means 26 in the car 11 and outputs the abnormality information to the voice announcement means. 27, an audio announcement is output. This notifies the passenger of the abnormal state of the air pressure control. Furthermore, the abnormal state of the air pressure control is notified to the outside of the car, for example, to an abnormal state communication means 28 provided in an elevator monitoring panel, that the atmospheric pressure control device 12 is in an abnormal state.
[0020]
Next, the operation will be described. The air pressure condition abnormality monitoring means 20 of the abnormality monitoring device 18 controls whether the pressure inside the car measured by the car internal pressure measuring means 13 is controlled within a normal range or the time change rate of the pressure inside the car is normal. It is monitored whether the air pressure is controlled within the range, or whether the air pressure inside and outside the car measured by the car inside / outside air pressure difference measuring means 19 is controlled without exceeding the normal range. The pressure pattern abnormality monitoring means 21 receives the pressure pattern generated by the pressure pattern generation means 15 and constantly monitors whether the pressure control device 12 is trying to control the inside pressure of the car in a normal range.
[0021]
Further, the atmospheric pressure controller abnormality monitoring means 22 constantly monitors whether the atmospheric pressure controller 14 is operating normally. For example, the atmospheric pressure controller abnormality monitoring means 22 outputs a monitoring signal to the atmospheric pressure controller 14, and the atmospheric pressure controller 14 returns a normality confirmation signal corresponding to the received monitoring signal to the atmospheric pressure controller abnormality monitoring means 22, and the pressure controller abnormality The monitoring means 22 constantly monitors the normal confirmation signal. Alternatively, the pressure controller 14 outputs an operation confirmation signal to the pressure controller abnormality monitoring means 22 in a certain period, and the pressure controller abnormality monitoring means 22 constantly monitors whether the operation confirmation signal is input within a predetermined period. I do.
[0022]
When an abnormality is detected by the monitoring of the atmospheric pressure condition abnormality monitoring means 20, the atmospheric pressure pattern abnormality monitoring means 21, and the atmospheric pressure controller abnormality monitoring means 22 of the abnormality monitoring device 18, the abnormality information is input to the elevator controller 24. When the elevator controller 24 receives the abnormality information from the abnormality monitoring device 18, the elevator controller 24 outputs a command to the air pressure controller 14 of the air pressure control device 12 to stop the air pressure control or to perform a low-speed operation control for ventilation in the car. Further, it outputs a command signal to the speed pattern generating means 25 at a timing for generating a traveling speed pattern for abnormal pressure control. As a result, the car 11 is caused to run at a running speed based on a pressure change that reduces the discomfort to the passenger.
[0023]
FIG. 2 is a diagram illustrating a driving speed pattern for an abnormal pressure control when the abnormal information of the atmospheric pressure control is input while the car 11 is accelerating and has not reached the traveling speed for the abnormal pressure control. It is explanatory drawing of a shift.
[0024]
As shown in FIG. 2, it is assumed that an abnormality in the air pressure control is detected at a time point err in a state where the car is accelerating and the traveling speed v of the car has not reached the traveling speed V1 for the abnormal pressure control. . Then, the elevator controller 24 subtracts the transition traveling speed difference Vj necessary for smoothly transitioning from the traveling speed Verr of the car at the time of detecting the atmospheric pressure control abnormality to the traveling speed V1 at the time of detecting the atmospheric pressure control abnormality, and determines the transition traveling speed. (V1-Vj) is obtained. The transition traveling speed (V1-Vj) is a traveling speed at which the jerk is changed.
[0025]
Then, it is determined whether or not the transition traveling speed (V1-Vj) is equal to or lower than the current traveling speed Verr, and if the current traveling speed Verr of the car is equal to or lower than the transition traveling speed (V1-Vj) (Verr ≦ In (V1-Vj), the traveling speed of the car is accelerated to the transition traveling speed (V1-Vj), and thereafter, the transition to the traveling speed pattern to the traveling speed V1 at the time of detecting the abnormality in the atmospheric pressure control is started. V0 in FIG. 2 is the rated speed of the car at normal time.
[0026]
On the other hand, when the current traveling speed Verr of the car exceeds the transition traveling speed (V1-Vj) (Verr> V1-Vj), as shown in FIG. Start migrating to. Assuming that a car pressure is abnormally detected at a time err when the car is accelerating and the car speed v exceeds the barometric pressure control running speed V1, the current car is running. Since the speed Verr exceeds the transition traveling speed (V1−Vj), the transition to the traveling speed V1 for abnormal pressure control immediately starts. That is, the vehicle is accelerated to the traveling speed (Verr + Vj) to which the speed difference Vj for smoothly moving the traveling speed v to the current traveling speed Verr of the car is added, and the vehicle is driven at the traveling speed (Verr + Vj) for several seconds. To the running speed V1 at the time of detecting the atmospheric pressure control abnormality. As a result, it is possible to shift to the traveling speed V1 for abnormal pressure control while reducing discomfort to passengers due to sudden changes in acceleration.
[0027]
Next, when the car is traveling at the rated speed V0 and an air pressure control abnormality is detected, as shown in FIG. 4, the atmospheric pressure control abnormality is detected from the traveling speed Verr (rated speed V0) at the detection time ter. The running speed is reduced to the running speed V1.
[0028]
Next, when a pressure control abnormality is detected while the car is decelerating, as shown in FIG. 5, the speed pattern is not shifted to the traveling speed V1 when the pressure control abnormality is detected. Decelerate according to the speed pattern.
[0029]
The abnormality information detected by the abnormality monitoring device 12 is output from the elevator controller 24 to a message display means 26 provided in the car 11 and a message indicating that the operation of the air pressure control device 12 is abnormal is displayed. Passed on to passengers. The abnormality information is also output to the voice announcement means 27 provided in the car 11 and a message indicating that the operation of the air pressure control device 12 is abnormal is transmitted to the passenger by voice announcement.
[0030]
On the other hand, the abnormality information is also output from the elevator controller 24 to the abnormal state communication means 28, and the operation abnormality of the air pressure control device 12 is notified not only to the inside of the car 11 but also to a monitoring panel such as a building monitoring room or a maintenance center. Inform. Here, the message display, the voice announcement, and the notification of the abnormal state not only inform the operation abnormality of the air pressure control device 12 but also inform the passengers and maintenance staff of the detected abnormal location.
[0031]
Further, the abnormality information detected by the abnormality monitoring device 12 is also input to the abnormal state storage unit 23, and records the abnormal state when the atmospheric pressure control abnormality is detected. The abnormal state storage unit 23 also records abnormal information from the elevator controller 24 together with date and time information at the time of detecting the atmospheric pressure control abnormality. Thereby, it is possible to easily find and repair an abnormal part of the atmospheric pressure control device 12. Also, by sampling and recording the control signal of the atmospheric pressure control device 12 before and after the detection of the atmospheric pressure control abnormality, the state of the abnormal operation can be clearly understood, so that the abnormal point of the atmospheric pressure control device can be more easily found and repaired. Become.
[0032]
That is, the elevator controller 24 always updates and stores a predetermined number of the sampled control signals, and when the abnormal pressure control is detected, stores the updated and stored past data in the abnormal state storage means 23. At the same time, a predetermined number of sampled control signals from the time when the atmospheric pressure control abnormality is detected are stored in the abnormal state storage means 23.
[0033]
In the above description, the atmospheric pressure state abnormality monitoring means 20 of the abnormality monitoring device 20 detects an abnormality in the atmospheric pressure state by a signal from the car inside pressure measuring means 13 or a signal from the inside / outside car pressure difference measuring means 19, An additional signal from the abnormality detection means of the intake blower driving device 16A or the exhaust blower driving device 16B is additionally inputted and detected as an atmospheric pressure condition abnormality even when the intake blower driving device 16A or the exhaust blower driving device 16B becomes abnormal. Is also possible.
[0034]
