[Problems to be solved by the invention]
However, as described above, in the conventional elevator, the extension cannot be performed unless the operation of the extension button or the like is performed in order to perform the extension. Also, when there is a passenger in the car, since the car load is not unloaded, the passenger must operate the door close button in order to eliminate the extension. Further, there is no function of extending the opening from the landing, and at present, the opening is extended by reversing the door closing operation by continuously holding down the safety shoe.
[0005]
An object of the present invention is to solve the above-mentioned problem, and to provide an elevator control device that can easily get on and off by controlling an opening extension operation according to the operation state of a safety shoe.
[0006]
[Means for Solving the Problems]
An elevator control device according to the present invention includes a door full-open detector that detects a full-open state of a car door, a safety shoe operation detector that detects an operation of the safety shoe, and a detection signal of the door full-open detector. Control means for setting the door extension operation and performing the extension operation when the safety shoe operates for a predetermined time based on the detection signal of the safety shoe operation detector when the door is fully opened. It is provided with.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a diagram showing an overall configuration of an elevator control device according to the present invention. As shown in FIG. 1, a safety shoe 2 is provided at the tip of the door 4 of the car 1 to open the door when the door is closed. Further, a car operation panel in the car 1 has a door closing button 6, a car load detector 7 is attached to the car floor, and a car control device 14 is provided at the top of the car. The car control device 14 is connected to the control panel 10, controls the driving of the door 4 of the car 1 by the control panel 10, and controls the driving of the motor 11 so that the car 1 can move up and down in the hoistway. Note that a counterweight 13 is connected to the car 1 via a rope 12.
[0008]
FIG. 2 is a diagram showing a detailed configuration of the door 4 of the car 1. As shown in FIG. 2, the safety shoe 2 is provided with a safety shoe operation detector 3, and the door 4 is provided with a fully open detector 5 which detects a fully opened state of the door 4.
[0009]
Embodiment 1 FIG.
Next, an operation according to the first embodiment in the elevator control device having the above configuration will be described. FIG. 3 is a flowchart for explaining the opening extension operation of the control panel 10 according to the first embodiment. As shown in FIG. 3, it is determined whether or not the door 4 is fully opened based on a detection signal of the fully opened detector 5 of the door 4 (step S11). If it is not fully opened, the process is terminated. If it is fully opened, it is determined whether or not the safety shoe 2 has operated for a predetermined time (for example, 3 seconds) based on a detection signal of the safety shoe operation detector 3 ( Step S12). If it has been operating for the predetermined time, the opening extension operation flag is set, and the opening extension operation is enabled (step S13).
[0010]
Thereafter, it is determined whether or not the safety shoe 2 is operating (step S14). If the safety shoe 2 is operating, the process returns to step S12. If not, the opening extension operation flag is set. Is determined (step S15), and if it is valid, the opening extension operation is performed (step S16). After a predetermined time (eg, 1 minute) has elapsed, the opening extension operation is released (step S15). S17), a door closing operation is performed (step S18). If invalid in step S15, a door closing operation is performed (step S18). Although not shown here, if the safety shoe is operated for a predetermined time again during the opening extension operation of step S16, the process returns to step S12.
[0011]
Therefore, according to the first embodiment, when the door is fully opened based on the detection signal of the door full-open detector 5, the safety shoe 2 operates for a predetermined time based on the detection signal of the safety shoe operation detector 3. Since the door opening time is extended when the operation is detected, the opening extension operation can be performed without attaching the opening extension button. Also, when getting on and off the elevator, when the door open button or open extension button in the car is not operated, it is common to get on and off while holding the safety shoe, but at this time, hold the luggage in both hands and get on and off the safety shoe. In some cases, it is possible to prevent the reversing door from opening after the door once closes and hits the body. In addition, since there is no function of extending the opening from the landing, a safety shoe is operated from the landing side to wait for a passenger to enter the vehicle in many cases, and the opening extension operation from the landing can be performed by a simple operation.
[0012]
Embodiment 2 FIG.
Next, an operation according to the second embodiment will be described. In the second embodiment, a description will be given of an operation of detecting a failure of the safety shoe 2 by the control panel 10 having the same configuration as the first embodiment. FIG. 4 is a flowchart illustrating a failure detection operation of safety shoe 2 at the time of door opening extension operation of control panel 10 according to the second embodiment.
[0013]
In the flowchart shown in FIG. 4, steps S11 to S18 are the same as those in FIG. If it is determined in step S14 that the safety shoe 2 is not operating, the process proceeds to step S21, and it is determined whether the safety shoe 2 has been operating for a long time (for example, one minute). If the safety shoe 2 has been operating for a long time, it is determined that an object is caught between the door 4 and the safety shoe 2 and it is not possible to shift to the door closing operation, and the abnormality of the safety shoe 2 is detected (step S22). Although not shown here, an abnormality detection is reported to a monitoring panel or the like. In step S21, when the safety shoe 2 has not been operated for a long time, or after step S22, the process returns to step S12.
[0014]
Therefore, according to the second embodiment, when the safety shoe 2 opens and extends, when a state in which an object is caught between the door 4 and the safety shoe 2 continues for a long time, a failure state due to the inability to use the elevator. Can be detected and recovery can be made immediately.
[0015]
Embodiment 3 FIG.
Next, an operation according to the third embodiment will be described. In the third embodiment, a description will be given of an operation of detecting a failure of the safety shoe 2 by the control panel 10 having the same configuration as the first embodiment. FIG. 5 is a flowchart illustrating a failure detection operation of safety shoe 2 during a door opening extension operation of control panel 10 according to the third embodiment.
[0016]
In the flowchart shown in FIG. 5, steps S18 and S22 are the same as those in FIGS. At the time of opening extension by the safety shoe 2 in step S30, it is determined whether or not the door closing button 6 is operated in step S31. If the safety shoe 2 is not operating in step S32, the process proceeds to the door closing operation in step S18. If the safety shoe 2 is operating even if the door closing button is operated for a predetermined time (for example, 3 seconds) in step S33 during operation, there is an object between the door 4 and the safety shoe 2. It is determined that it is not possible to shift to the door closing operation. Although not shown here, an alarm is issued to a monitoring panel or the like by the abnormality detection in step S22.
[0017]
Therefore, according to the third embodiment, when the safety shoe 2 opens and extends, when the state where an object is sandwiched between the door 4 and the safety shoe 2 continues, the door closing button 6 is operated to execute the operation. It is possible to detect a failure state in a shorter time than in the second embodiment and to recover quickly.
[0018]
Embodiment 4 FIG.
Next, an operation according to the fourth embodiment will be described. In the fourth embodiment, a description will be given of an operation having the same configuration as that of the first embodiment, and enabling the opening extension operation until the boarding detection is completed by the control panel 10 based on the detection value of the car load detection device 7. FIG. 6 is a flowchart illustrating an operation of validating the opening extension operation until the boarding detection is completed during the door opening extension operation of the control panel 10 according to the fourth embodiment.
[0019]
In the flowchart shown in FIG. 6, steps S11 to S18 are the same as those in FIG. First, in step S41, a passenger is determined based on a hall call response. A step S42 decides whether or not there is no car call, and decides whether or not the passengers in the car are on board or who are all the disembarking passengers. When steps S41 and S42 are established and the opening extension operation is established (after the lapse of steps S11-S16), the opening is performed as long as the passenger is not in the car and the car call is not registered in step S43. Continue extension operation. In step S44, when the car load is stabilized for a predetermined time (for example, one second), it is considered that the passenger has completed boarding, and the opening extension operation in step S17 is cancelled.
[0020]
Therefore, according to the fourth embodiment, since the car call is not registered, the car can be temporarily occupied, so that the opening extension operation can be performed until the boarding is completed. Moreover, since the opening extension operation is canceled by recognizing the boarding completion, the operation of the door closing button is unnecessary.
[0021]
Embodiment 5 FIG.
Next, an operation according to the fifth embodiment will be described. In the fifth embodiment, a description will be given of an operation having the same configuration as that of the first embodiment, and enabling the opening extension operation until the getting-off detection is completed by the control panel 10 based on the detection value of the car load detection device 7. FIG. 7 is a flowchart illustrating an operation of validating the opening extension operation until detection of getting off is completed during the door opening extension operation of the control panel 10 according to the fifth embodiment.
[0022]
In the flowchart shown in FIG. 7, steps S11 to S18 are the same as in FIG. 3, and step S44 is the same as in FIG. First, in step S51, a determination is made as to whether or not a passenger gets off a car by car call. A step S52 decides that there is no passenger by the hall call. When steps S51 and S52 are established and the opening extension operation is established (after the lapse of steps S11-S16), in step S44, if the car load is stabilized for a predetermined time (for example, 1 second), the getting-off is performed. It is considered that the operation has been completed, and the opening extension operation of step S17 is released.
[0023]
Therefore, according to the fifth embodiment, when there are many disembarking passengers, there is a situation where passengers near the operation panel in the car 1 must operate the door opening button. This can eliminate the hassle of having a person get off at the end. In addition, since the extension operation is canceled by recognizing the getting-off completion, the operation of the door closing button 6 is unnecessary.
[0024]
Embodiment 6 FIG.
Next, an operation according to the sixth embodiment will be described. In the sixth embodiment, the same configuration as that of the first embodiment is provided, and when both the getting-off and the getting-on are performed by the control panel 10, the opening extension operation is performed based on the detection value of the car load detecting device 7 until the getting-on detection is completed. The operation for validating is described. FIG. 8 is a flowchart illustrating an operation of validating the opening extension operation until the boarding detection is completed when both the getting off and the boarding are performed during the door opening extension operation of the control panel 10 according to the sixth embodiment.
[0025]
In the flowchart shown in FIG. 8, steps S11 to S18, step S41, step S44, and step S51 are the same as those in FIG. 3, FIG. 6, and FIG. First, in steps S51 and S41, it is determined whether both the disembarking passenger and the passenger are established. When step S51 and step S41 are established and the opening extension operation is established (after the lapse of steps S11-S16), it is determined in step S61 whether or not the disembarking customer has exited. Thereafter, it is determined in step S62 whether or not the passenger is on board. Then, in step S44, when the car load is stabilized for a predetermined time (for example, one second), it is considered that the boarding has been completed, and the opening extension operation in step S17 is cancelled.
[0026]
Therefore, according to the sixth embodiment, when there are both a passenger and a disembarking passenger, there are many disembarking passengers, and it is possible to prevent the passengers from being unable to get on when the passengers are crowded near the elevator hall. . In addition, since the opening extension operation is canceled after boarding, the operation of the door closing button 6 is unnecessary.
[0027]
Embodiment 7 FIG.
Next, an operation according to the seventh embodiment will be described. In the seventh embodiment, a description will be given of an operation that has the same configuration as that of the first embodiment and cancels the opening extension operation when only the getting off is performed in response to the hall call by the control panel 10. FIG. 9 is a flowchart illustrating an operation for canceling the opening extension operation when only the getting off is performed in response to the landing call of the control panel 10 according to the seventh embodiment.
[0028]
In the flowchart shown in FIG. 9, steps S11 to S18, step S41, step S44, step S51, step S61, and step S62 are the same as those in FIGS. 3, 6, 7, and 8. First, in steps S51 and S41, it is determined whether both the disembarking passenger and the passenger are established. When step S51 and step S41 are established and the opening extension operation is established (after the lapse of steps S11-S16), it is determined in step S61 whether or not the disembarking customer has exited. Thereafter, it is determined in step S62 whether or not the passenger is on board. At this time, in step S71, when the car load does not increase and the car load is stabilized for a predetermined time (for example, 5 seconds), it is determined that there is no passenger in the hall, and the opening extension operation in step S17 is canceled.
[0029]
Therefore, according to the seventh embodiment, when both a passenger and a disembarking passenger are present, when the passenger leaves the place by operating a stairway button, etc., on a stair, or the like, when the boarding is not detected according to the sixth embodiment, In addition, since the opening extension operation is canceled, the operation of the door closing button 6 is unnecessary.
[0030]
