Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator operation control device, and in particular, a control device that controls slow control operation and normal operation for so-called weak people such as physically disabled people and the elderly. This invention relates to an elevator operation control device that can be used.

[Prior Art] As a conventional elevator operation control device of this type, there is a technique disclosed in Japanese Utility Model Application Publication No. 53-43663.

In hospitals, nursing homes, residences, etc., elevators are often used by the physically disabled and the elderly (hereinafter simply referred to as the vulnerable). Otherwise, their bodies may hit the elevator doors, which is extremely inconvenient for vulnerable people.

Therefore, in such cases, slow control operation of the elevator (hereinafter simply referred to as ``operation for the weak'') that matches the movements of the vulnerable person may be implemented, for example by making the elevator door open longer than during normal operation. ) is being carried out.

On the other hand, if all elevators are operated for people with disabilities, this is fine if there are many people who are vulnerable, but if the elevators are used only by ordinary people who are not vulnerable, the elevators will run slowly, which is extremely inconvenient. Therefore, in the above-mentioned publication, a dedicated button for the weak is provided in the elevator car and the elevator hall, and when the button for the weak is pressed, the elevator door opens for a longer time than usual. This is handled by slow controlled operation.

[Problems to be Solved by the Invention] In the conventional elevator operation control device as described above, a dedicated button for the weak is provided, and when the weak person presses this button, the elevator operation can be switched between the operation for the weak and the normal operation. I had switched to driving. Therefore, it is fine if a vulnerable person can press this dedicated landing button, but when the vulnerable person arrives at the landing, the elevator door is already open or the elevator car has stopped at that floor. When the vehicle is decelerating, there is not enough time to press the dedicated button. For this reason, even in cases where ordinary people who are not vulnerable can use the elevator car, they are unable to use the elevator car and are forced to use the next elevator car or another elevator car. It was extremely inconvenient for him.

Therefore, this invention was designed to be as convenient as possible for the weak.
An object of the present invention is to provide an elevator operation control device that allows a weak person to switch the elevator between slow control operation for the weak and normal operation.

[Means for Solving the Problems] An elevator operation control device according to the present invention includes a slow control operation means for operating an elevator according to a slow control operation, and an elevator landing control device that operates an elevator in a predetermined state when an elevator car is in a predetermined state. passenger speed detection means for detecting the approaching speed of a passenger approaching the vehicle; and operation switching means for switching the operation of the elevator from normal operation to the slow control operation for a predetermined period of time in accordance with the output of the passenger speed detection means. It is equipped with the following.

[Operations] In the present invention, when the elevator car is in a predetermined state, the passenger speed detection means detects the approaching speed of a passenger approaching the elevator hall, and from the approaching speed it is determined whether the passenger is a vulnerable person or not. and selects elevator operation based on the judgment result. That is, in the case of a weak person, the operation of the elevator is switched from normal operation to slow control operation, and the elevator is operated in a slow control operation in accordance with the slow control operation, and in the case of a non-weak person, the elevator is operated normally.

Next, the operation of the elevator operation control device having the above configuration will be explained using FIG. 3.

FIG. 3 is a flowchart showing an example of the operation of an elevator operation control device according to an embodiment of the present invention.

In this diagram, the elevator car is currently on a predetermined floor (floor X).
The following describes the case where the elevator arrives at the elevator and starts opening the elevator door. Note that the series of operations in this flowchart is executed according to a predetermined program, and this program is called and executed during execution of the main program.

In the figure, it is determined in step S1 whether the elevator car has arrived at the X floor, and in step S2 it is determined whether or not there are passengers approaching the elevator landing on the X floor. If there is no passenger, the normal operation returns to the main program routine, and if there is a passenger approaching, the approaching speed of the passenger approaching the elevator landing is detected in step S3. The determination in step S1 is performed by the microcomputer (21) based on the girder position signal (8), and the determination in step S2 and the operation in step s3 are performed by the microcomputer (21) based on the signal from the speed detection means (1). ). Then, in step S4, it is determined whether the approaching speed is less than a predetermined value (for example, 2 km/h), and if the approaching speed is less than the predetermined value, it is determined that the approaching passenger is a normal citizen who is not vulnerable. If it is determined that this is the case, the process returns to the main program routine, and if the approaching speed is greater than a predetermined value, it is determined that the approaching passenger is a vulnerable passenger, and the first vulnerable passenger driving mode is set in step S5.

Both the judgment in step s4 and the operation in step S5 are performed by the microcomputer (21). Next, in step s6, the number of passengers in the elevator car is detected,
In step S7, the number of passengers in the car is a predetermined value (for example,
If the number of passengers in the car is less than or equal to a predetermined value, the process proceeds to step S8, where the second driving mode for vulnerable persons is set. The operation of step S6 is performed by the number of passengers detecting means (3), and the judgment of step S7 and the operation of step S8 are carried out by the microcomputer (21) based on the signal from the number of passengers detecting means (3). It is done. By setting this second vulnerable operation mode, the closing speed of the elevator door will be slower than the normal speed (for example, 1/2 the normal speed), and the door opening time will be longer than the normal time (for example, (5 seconds becomes 10 seconds), and furthermore, the instruction by the door opening button (6) becomes invalid. Further, if the number of passengers in the car is larger than the predetermined value, the process jumps to step S8 and proceeds to step S9, so that the second weak-person driving mode is not set. Therefore, in this case, the closing speed and opening time of the elevator door remain as normal, and instructions using the door opening button (6) are also valid. In this way, when the number of passengers in the elevator car is large, the second vulnerable person operation is avoided because if the number of passengers in the car is large, other passengers in the car help the vulnerable person get on board. This is because it is considered highly likely.

In step S9, it is determined whether or not the elevator door opening time has ended, and if the door opening time has ended, the door closing operation is started in step SIO, and step 811
Then, it is determined whether the door closing operation is completed. The judgment in step S11 is made by the microcomputer (21) based on the door closing completion detection signal (7), and when the door closing operation is completed, a car call is registered using the destination button (9) in the box in step S12. If the car call is registered, the elevator car starts running in step S14. Note that since the traveling speed at this time is set to the first weak driving mode, the acceleration/deceleration is lower than normal (for example, from 0.9 m/5ee2 to 0.7 m/5ec2). On the other hand, if the elevator door has been closed in step Sll and the car call has not been registered in step S12, wait for the car call to be registered for a predetermined period of time (for example, 10 seconds) in step 81B;
If the car call is not registered even after that time has passed,
In response to hall call registration using the hall button (11), step S
At 14, the elevator starts running. Note that the traveling speed at this time is also the acceleration/deceleration according to the first weak-person driving mode.

As described above, the elevator operation control device of this embodiment has a slow control operation means for operating the elevator in accordance with the slow control operation corresponding to the movements of vulnerable people, that is, the slow control operation means reduces the acceleration/deceleration of the elevator car and calls the car. A first operating means for vulnerable users (2) that secures the time for registration, and a second operating means for vulnerable users (4) that reduces the closing speed of the elevator door, extends the door opening time, and invalidates instructions from the door open button. ), and when the elevator car is in a predetermined state (i.e., the elevator car has arrived at a predetermined floor (floor X) and the elevator door is in the open state), ) passenger speed detecting means for detecting the approaching speed of a passenger approaching the elevator landing, that is, the passenger speed detecting means for performing the operations of step S2 and step S3 using the speed detecting means (1); an operation switching means for switching the operation of the elevator from the normal operation to the slow control operation in accordance with the output of the detection means, that is, in accordance with the determination in step S4; The driving mode includes driving switching means for switching the driving mode from the normal driving mode to the slow control driving mode by performing the setting operation of the second weak-person driving mode in step S6.

Then, the approach speed of a passenger approaching the elevator hall is detected, it is determined from the approach speed whether the passenger is vulnerable, and the elevator operation is selected according to the result of the determination. In other words, in the case of a weak person, the operation of the elevator is switched from normal operation to operation for the weak, and the elevator is operated in a slow controlled manner that matches the movements of the weak person.In the case of an ordinary person who is not a weak person, the normal operation of the elevator is changed. Let's do it.

Therefore, in the elevator operation control device of this embodiment, there is no need for a dedicated button for the vulnerable person as in the past (as soon as the vulnerable person approaches the elevator hall, the elevator operation is changed from normal operation to normal operation). Switches to slow control operation.For this reason, even when the elevator door is already open when a vulnerable person arrives at the landing, or when the elevator car is decelerating to stop at that floor, etc. , the elevator car can be used, and the operation is extremely convenient for the vulnerable.Furthermore, when this elevator is used only by ordinary people who are not vulnerable, the elevator is operated in a way that is suitable for ordinary people. Since normal operation is performed, there is no inconvenience such as slow elevator operation.

As a result, with this elevator operation control device, it is possible to switch the elevator between the operation for the weak and the normal operation from the point of view of the weak, so as to make it as convenient as possible for the weak. In addition, in the elevator operation control device having this configuration, a dedicated button for the weaker persons may be provided in the elevator car or in the elevator hall, as in the conventional case.

By the way, in the above embodiment, the slow control operation means is set to
It is divided into two modes: the driving method (2) and the second driving method for vulnerable people (4).If the number of passengers in the car is large and help from other passengers is likely to be expected, the second driving method for vulnerable people (4) is used. Have you explained the elevator operation control device that reduces the closing speed of the elevator door, extends the door opening time, and disables the door opening button to suppress the decline in operating efficiency as much as possible? Alternatively, the vehicle may be operated only for the disabled, and the vehicle may be operated for the disabled regardless of the number of passengers.

Further, in the above embodiment, when the elevator car is stopped and the elevator door is open and a passenger approaches the elevator landing on the floor, the elevator operation control performs the operations from step S1 to step S4. As explained about the device, when the elevator car has decided to stop and started decelerating, steps S2 to S
It is also possible to use an elevator operation control device that performs the operation of No. 4. However, in this case, speed detection means for detecting the speed of the elevator car is required at the elevator hall.

In short, it is easy to detect the approaching speed of a passenger approaching an elevator landing when the elevator car is in a predetermined state. , or when the vehicle is decelerating to stop at that floor.

Furthermore, although the timing of canceling the slow control operation mode was not described in the above embodiment, operation with reduced acceleration/deceleration is performed until the elevator car arrives at the floor where the car call was registered on the floor where the vulnerable person got into the elevator car. continues, and the reduction in the closing speed of the elevator door, the extension of the door opening time, and the disabling of the door opening button do not work if the general call is stopped during operation until the elevator car arrives at the car call floor. , it operates only on a dedicated car call floor, and thereafter, slow control operation will not be performed until the next detection of boarding of a vulnerable person. this is,
This is because the slow controlled operation of the elevator is sufficient only for a predetermined period of time during which a vulnerable person is actually using the elevator.

[Effects of the Invention As described above, the elevator operation control device of the present invention has the following effects:
comprising a slow control operation means, a passenger speed detection means, and an operation switching means, the passenger speed detection means detects the approaching speed of a passenger approaching an elevator landing when the elevator car is in a predetermined state; Based on the approach speed, it is determined whether the passenger is a vulnerable person or not. Depending on the judgment result, if the passenger is a vulnerable person, the elevator operation is switched from normal operation to slow control operation, and the elevator operation is adjusted to match the slow control operation. Slow control operation is performed, and if the person is not a vulnerable person, normal operation of the elevator is performed, so if a weak person approaches the elevator landing, the elevator operation will switch from normal operation to slow control operation, and the weak person will move to the elevator landing. When you arrive at
Even when the elevator door is already open or the elevator car is decelerating to stop at the floor, the elevator car can be used, making the operation extremely convenient for the weak. will be carried out.
