Abstract

PURPOSE:To enable for a passenger to selectively set the running direction of a cage toward a desired floor with priority over other call signals by applying the constitution wherein when a later destination floor call signal is newly registered during the stop of a cage at a hall, the running direction of the cage is reversed with priority over other call signals. CONSTITUTION:When a passenger at the second floor hall presses a hall button for going down to a lower floor during the waiting time of a cage 5 with a door closed at the first floor hall in a non-directional condition, the cage 5 starts to run upward. When another passenger at the third floor hall presses a hall button 8 for going down to a lower floor during the aforesaid running of the cage 5, the hall call is registered as a call signal from the third floor. When the cage 5 stops at the second floor hall in response to the hall call, the register of the hall call from the second floor is cancelled, the passenger on board during a door open time presses the first floor button as a destination for registering a new call signal for the first floor respectively, the cage 5 closes the door thereof, runs and stops at the first floor hall with priority over the third floor hall call previously registered timely. In addition, the register of the first floor call as a destination is cancelled, and the passenger gets off the cage 5. Thereafter, the door closes and the cage 5 starts to run in response to a call from the third floor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method of operating a home elevator installed in a private residence or the like.

[Conventional technology]

In recent years, due to the increase in the elderly population and the number of two households living together, as well as the shrinking of housing lots due to housing land conditions, single-person residences are becoming more and more three-dimensional, in order to reduce the burden and obstacles of going up and down one flight of stairs.

2. Description of the Related Art The need for elevators for private residences, which can accommodate three to four stories and have a capacity of about three people, is increasing, and there is a need for an elevator operating method suitable for this purpose.

FIG. 3 is a system diagram of an elevator that implements the conventional operating method and the operating method of the embodiment of the present invention.

FIG. 4 is an internal system diagram of the control panel (1) in FIG. 3.

In Figures 3 and 4, (1) is the control panel, (2) is the motor,
(3) is the hoisting machine, (4) is the counterbalance, (5) is the car plan, (61 is the car operation panel with the destination floor button, (7)
~ α (1 is one non-directional landing button provided at the landing on each floor, an is the central processing unit (hereinafter abbreviated as CPU)),
a2 is a group of signal lines such as an address bus, data bus, and control bus; a3 is a read-only memory (hereinafter abbreviated as ROM) that stores an elevator operation program including a procedure for determining the car driving direction; and Q4 is a calculation result. Read-write memory (hereinafter abbreviated as RAM) that temporarily stores information such as
, Q9 is a signal converter (voltage level conversion, analog/digital conversion, serial/variable It is an input/output interface device that performs conversion, etc.

An outline of the operation of the elevator configured as described above is as follows. When a passenger presses the destination floor button on the car operation panel (6) or the landing button (7) ~ number of landings on each floor, 0PUQII on the control panel (1) activates the destination floor button signal or landing button signal. Detected.

The signals are read into the RAM Q4 through the input/output interface 7 ace device α5 and registered as destination floor call signals and hall call signals, respectively. The destination floor call signal and hall call signal registered on the RAM+141 are not erased until the car responds. The cpnan constantly repeatedly executes the operating direction determination procedure program, which is a subroutine of the operating program stored in the ROM+13, monitors the presence or absence of a call signal, performs arithmetic processing according to the operating direction determination procedure, and determines the direction of the elevator car. Set driving direction. According to the result, cpou will configure the input/output interface &a! i, the motor (2) is fully driven and the car (5) is driven in that direction to respond to the registered destination floor call signal and hall call signal.

FIG. 5 is a program flowchart showing a procedure for determining an operating direction in a conventional elevator operating method, and the symbols in N indicate steps for performing determination or processing. The main flow in FIG. 5 will be explained.

If there is a call signal while the car is waiting on a non-directional floor, the car's driving direction is set to the direction of that call signal.
21), @. When the car has a driving direction, if there is a destination floor call or hall call signal in front of it, the driving direction is maintained as it is (2) 0110υ (to), so the destination floor call and hall call signal in front are Until the signal is cleared, the call in front is given priority over the destination floor call and hall call in the rear (front call priority system). Or, if there is a hall call signal, reverse the driving direction and go to @shi113.
Respond to υ6's friend call signal later. If there is no call signal anywhere, the direction of the car is set to no direction and the car waits on that floor.

Note that step 1 = is a procedure for determining whether the driving direction can be reversed (-).In order to avoid reversing the driving direction even if there is a slight delay in registering the call signal ahead, the car is rotated in a predetermined manner after the car stops at the landing. YES will not appear until the time has elapsed, and when Matakata reaches the highest or lowest floor, YFX8 will appear.

[Problem to be solved by the invention]

In the conventional elevator operating method. Since the car driving direction determination procedure is configured as described above, 2 For example,
When a passenger presses the landing button to call a car at an intermediate floor landing to go downstairs, even if there is a difference in waiting time, if the car already has an upward direction, the car will go to the highest floor where the call signal is located. The advantage is that the responses follow a predictable order: the driver responds to the driver's request, then reverses direction of driving and returns.

However, in home elevators installed for private residences,
The capacity is about 3 people, and there is a request for exclusive use.1 For example, if a passenger is in a car on an intermediate floor and there is no more space in the car due to luggage being carried downstairs, or if there is an emergency, the car will be turned upward. has driving direction.

In addition, if there is a call signal in front of the car, the car remains in the same direction and travels upwards, so there is a problem in that the car cannot immediately go downstairs.

This invention was made in order to solve the above-mentioned problem, and the elevator operating direction is given priority over other calls in the direction of the destination floor call by the destination floor button pressed by the passenger who has boarded the car. Select and set. The objective is to obtain a driving method that includes a driving direction determination procedure.

[Means to solve the problem]

In order to achieve the above object, 2. In the elevator operation direction determination procedure of the present invention, when a rear destination floor call signal is newly registered while the car is stopped at a landing, it is given priority over other call signals. , the driving direction of the car is reversed.

[Effect]

In the elevator operation direction determination procedure configured as above, if a rear destination floor call signal is newly registered while the car is stopped at the landing, the car operation will be started with priority over other call signals. Since the direction is reversed, the elevator operating direction can be selected and set in the direction of the destination floor call by the new destination floor button pressed by a passenger who has boarded the car, giving priority to other call signals. I can do it.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 shows an elevator operating method according to an embodiment of the present invention. This is a program flowchart showing a driving direction determination procedure, and the main flow in FIG. 8 will be explained.

If there is a new floor call or a new landing call while the car is waiting at the landing with no direction, the driving direction is set to that direction CL!
When IC2υ@0 has the driving direction, if there is a new destination floor call in front, α3υ@(to), which maintains the driving direction, will change the rear destination while the car is stopped at the landing. If there is a floor call, the car will respond to the destination floor call of the passenger in the even c+D@atn5° car, reversing the driving direction, giving priority to other calls, ie.

If there are no passengers in the car and there is a call for a landing ahead that has not yet been answered, cl! maintains the driving direction! 1
aυ (I) @＼. If there is only a rear hall call, reverse the driving direction C) [11211G! 2 (c) @ (support). If there is no call, En (1) sets the car to no direction and waits on that floor.

FIG. 2 is a diagram illustrating an example of the movement of an elevator car in which the driving direction determination procedure of FIG. 1 is carried out. The movement of the car when the and landing buttons are pressed in the following time order will be explained.

When the car is waiting with the door closed at the landing on the first floor with no direction (state 40),
When a passenger on the 2nd floor boarding area presses the landing button (9) t- to go downstairs, the procedure for determining whether there is a call for the next floor or a landing call is YES, and since the car is waiting with no direction, there is no driving direction. The procedure Qυ for determining is No, the procedure @ for setting the driving direction in the direction of the destination floor call or landing call is set to the upward direction, and the car (5) starts traveling upward (state 41
). When a passenger on the third floor landing presses the landing button (8) to go downstairs while the car is traveling upward, the third floor landing button signal is registered as the third floor landing call signal (state 42).

The car responds to the 2nd floor landing call, stops at the 2nd floor landing, and 2
When a passenger who cancels the registration of the floor call signal and boards the train while the first door is open presses the destination floor button 1st floor, a new destination floor call signal for the 1st floor is registered.

Step □□□Q11 is YES, step @ to determine whether the newly registered destination floor call signal is ahead is No, step (to)
is YES, and the driving direction of the car is reversed downward in step 4, giving priority to the call on the third floor in front of the driving direction registered one hour earlier (state 46).

The car closes its door and starts running downward (state 47).

The car stops at the landing on the first floor, cancels the registration for the destination floor call on the first floor, opens one door, and allows passengers to get off. next.

The 3rd floor boarding call remains, so 1st step is YFi
g, Step @Ω (Foundation) is No, Step (Support) is 1st floor (lowest floor), so YES, and since it is 2nd step, the driving direction should be reversed upwards (State 48), After closing the door of the car, Start traveling upwards.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

In the car driving direction determination procedure in the elevator operating method of the present invention, when a rear destination floor call signal is newly registered while the car is stopped at a car landing, the car is given priority over other call signals. Since the driving direction of the car is reversed, the passenger of the car can select and set the driving direction of the car in the direction of the destination floor, giving priority to other call signals, which increases the exclusive use of the car. This has the effect of allowing you to go directly to your destination floor when there is no more room in the car or in case of an emergency.

Although the two-step procedure may delay the response to a single-hall call, it can be said that there is no practical problem considering the frequency of use of the two-person residential elevator and the fact that there are few places where the elevator stops.
