The present invention relates to a driving method of a home elevator installed in a private house.

In recent years, as the number of elderly households and second-generation households have increased, and residential lands have narrowed due to the circumstances of housing, more three-dimensionalization of private houses has occurred, and three or four-floor buildings and three gardens are needed to reduce the burden and obstacles of climbing stairs. The necessity of an elevator for a private house increases, and a suitable driving method of the elevator is required.

3 is a system diagram of an elevator for carrying out the conventional operation method and the operation method of the embodiment of the present invention, and FIG. 4 is an internal system diagram of the control panel 1 of FIG. 3, 4, 1 is a control panel, 2 is a motor, 3 is a winch, 4 is a counterweight, 5 is a car, 6 is a car control panel with buttons on the destination floor, and 7 to 10 are installed on the platform of each floor. One directionless platform button, 11 is central processing unit (hereinafter referred to as CPU), 12 is signal line bundle of address bus, data bus, control bus, etc., 13 is operation program of elevator including driving direction determination procedure of car Read only memory (hereinafter referred to as ROM), 14 denotes a read-writable memory (hereinafter referred to as RAM) that temporarily stores operation results and the like, 15 denotes the CPU 11 and the operator panel 6, and An input / output interface device which performs signal conversion (voltage level conversion, analog / digital conversion, serial / parallel conversion, etc.) between elevator devices such as the landing buttons 7 to 10 and the motor 2.

The operation outline of the elevator configured as described above is as follows.

When the passenger presses the destination floor button of the car operating panel 6 or the platform buttons 7 to 10 of each floor, the CPU 11 of the control panel 1 detects such a destination floor button signal or the platform button signal. The RAM 14 reads and inputs the data to the RAM 14 through the input / output interface device 15, and registers each as a destination floor call signal and a boarding point call signal.

The destination floor call signal and the boarding point call signal registered on the RAM 14 are not erased until there is a car response. The CPU 11 continuously executes the program of the operation direction determination procedure, which is a subroutine of the operation program stored in the ROM 13, monitors the presence or absence of a call signal, calculates and processes the operation according to the operation direction determination procedure, and the elevator. Set the driving direction of car.

The CPU 11 drives the motor 2 through the input / output interface device 15 according to the result, drives the car 5 in that direction, and responds to the registered preceding floor call signal or platform call signal. Doing.

5 is a program flowchart showing a driving direction determination procedure in a conventional elevator driving method, and the symbols in the drawings indicate the steps of determining or processing, respectively. FIG. 6 is an exemplary diagram for explaining the movement of the car which performs the driving direction determination procedure of FIG.

The main flow of FIG. 5 is demonstrated with reference to FIG.

If there is a platform call on the 2nd floor, the driving direction is set upward by the process of Step 20 → (21) → (27). Start (state 41). The platform call on the 3rd floor was registered during the Kaga ascent (state 42), and the call to the second floor platform was canceled in response to the call to the platform on the 2nd floor of Kaga, and the call registration for the 2nd floor was canceled (state 43). Even if the passenger who boarded the bus presses the destination button on the 1st floor, there is a call in the driving direction ahead (the 3rd floor), so the up direction as the driving direction is maintained as it is by the steps 20 to 21 to 31. (State 46). In other words, after answering the landing call on the third floor, the driver switches to the first floor call (states 47 and 48).

Therefore, the front call is prioritized in front of the rear destination call and landing call until the front destination call and landing call signal disappears (front call priority method), and the highest or lowest level of the forward call signal is reached. If there is a destination floor call or platform call signal in the rear, in response to the call signal returned by the process of step 20? (21)? (31)? (25)? (29) Reverse the driving direction. If there is no call signal anywhere, the direction of the car is made non-directional by the step 20 to 30 processing, and the car is made to wait on the floor.

In addition, in step 25, it is determined whether or not the driving direction may be reversed. However, even if it is delayed to register the call signal in front of the vehicle, the car stops at the landing so that the driving direction is not reversed. Do not. If the car comes to the top or bottom floor, it becomes YES.

In the conventional elevator driving method, the procedure for determining the driving method of a car is configured as described above. For example, even if there is a difference in waiting time when a passenger presses the landing button and calls the car to go to the lower floor in the middle floor platform. If the car already has an upward direction, the car responds by going to the top floor where the call signal is located, and responding in a predictable order of returning from the driving direction.

However, in a home elevator installed for a private house, there are about three people in the capacity, and there is a demand for exclusive use, for example, when there is no more space in the car due to luggage carried by the passenger in the car from the middle floor to the lower floor. Even if there is urgent business, if the car keeps the driving direction upward and if there is a call signal in front, the driving direction of the car is maintained as it is and traveling upward. There was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the driving direction determination procedure of selecting and setting an operation direction of an elevator in preference to another call in the direction of a destination floor call by a destination floor button pressed by a car passenger. The purpose is to get the driving method to go.

In order to achieve the above object, in the driving direction determination procedure of the elevator of the present invention, if a new destination floor call signal is newly registered while the car is stopped at the platform, the driving direction of the car is reversed in preference to other call signals. It is.

In the elevator driving direction determination procedure as described above, if the destination floor call signal at the rear is newly registered while the car is stopped at the platform, the driving direction of the car is reversed in preference to other call signals. The driving direction of the elevator can be selected and set in preference to other call signals in the direction of the destination floor call by the passenger's newly pressed destination floor button.

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

1 is a program flowchart showing a driving direction determination procedure in an elevator driving method which is an embodiment of the present invention, and a description will be given of the main flow of the drawing.

When the car is waiting in the platform in a non-directional direction and a new destination floor call or platform call is newly generated, the driving direction is set to the direction by the steps 20 to 21 to 27 processes. If the car has a driving direction, if there is a new destination floor call, the driving direction is maintained as it is by the steps (20) (21) (22) (26), but while the car is stopped at the platform, If there is a destination floor call on the rear side, the process is reversed in the driving direction in advance of the other call by the process of step 20-(21)-(22)-(23)-(28)-(29). If the passenger completes a call to the destination floor of the car, that is, there are no passengers in the car, and there is a forward landing call that has not been answered yet, step 20 → (21) → (22) → (23) → ( 24) → (26) The operation direction is maintained as it is. If there is only a boarding point call in the rear, the driving direction is reversed by the process of step 20-(21)-(22)-(23)-(24)-(25)-(29). If there is no call anywhere, the process of step 20 → 30 causes the car to operate in the non-directional direction and wait on the floor.

In Fig. 1, steps 21 and 28 constitute a state discriminating means, step 22 constitutes a front discriminating means, step 23 constitutes a rear discriminating means, and step 29 constitutes a direction reversing means.

2 is a view for explaining an example of the movement of the car of the elevator performing the driving direction determination procedure of FIG. 1, and is performed for an elevator installed in a four-story building. Car movements when pressed in the time sequence described below will be explained.

First, in Fig. 2, each of the states 40 to 44 and 46 to 48 indicates the following state.

State 40... There is no call and Kaga is waiting on the first floor.

State 41... The platform call on the 2nd floor is registered, and the car starts driving upward.

State 42... The third floor call is registered while Kaga is traveling upward.

State 43... Kaga stops at the platform on the second floor in response to the platform call on the second floor and cancels the platform call on the second floor.

State 44... Waiting for opening on the 2nd floor of Kaga

State 46... In the state 44, the destination floor call signal on the first floor is newly registered and inverted downward.

State 47... Car starts traveling downward.

State 48... Arrive at 1st floor, cancel call signal on 1st floor, reverse direction and wait for opening on 1st floor.

In the state 40, when the guest of the landing on the second floor presses the landing button 9 to go to the first floor, the process proceeds to step 21 because a call is made in step 20. At this time, since the car is waiting in the non-direction, the process proceeds from step 21 to step 27, sets the driving direction upward and the car 5 starts traveling in the upward direction (state 41).

When the driver of the 3rd floor landing hall presses the landing button 8 to go to the lower floor while the car is traveling upward, the landing button signal on the 3rd floor is registered as the landing call signal on the 3rd floor (state 42). When the car stops at the platform on the second floor in response to the platform call on the second floor, the platform call on the second floor is canceled (state 43), and the door is opened for a while (state 44). At this time, since there is a landing call on the third floor in step 20, the process proceeds to step 21. In step 21, the process proceeds to step 22 because the direction is upward. In step 22, since the passenger has not pressed the destination floor call button, the process proceeds to step 23.

Since the passenger has not pressed the destination floor button at step 23 as well, the process proceeds to step 24. Since there is a call on the third floor in step 24, the flow advances to step 26 to maintain the driving direction as it is. However, if the passenger who was in the opening air waiting at the opening 44 presses the first floor button of the destination floor button of the operation panel 6 and newly registers the destination floor call signal on the first floor, there is a third floor platform call at step 20, so step 21 is performed. Proceed to In step 21, since the driving direction is upward, the process proceeds to step 22. In step 22, the destination floor call of the first floor is rearward, and therefore, the process proceeds to step 23. In step 23, the first floor is the rear destination floor, and therefore, the step 28 proceeds.

In step 28, since the car is stopped at the landing, the flow advances to step 29, in which the driving direction is inverted prior to calling the landing on the three floors ahead of the driving direction registered in time (state 46).

The car then closes and starts driving down (state 47).

If the car stops at the platform on the first floor, the registration registration for the destination floor on the first floor is canceled and the passenger opens. Next, if the platform call on the 3rd floor remains, it is the lowest floor, so the operation direction is reversed by the step (20) (21) → (22) → (23) → (24) → (25) → (29). (State 48), the car starts driving upward after closing.

Since this invention is comprised as mentioned above, it shows the effect described next.

In the procedure for determining the driving direction of the car in the driving direction of the elevator of the present invention, when the car stops at the platform, if a new destination floor call signal is newly registered, the driving direction of the car is reversed in preference to other call signals. Since the passengers in the car can select the driving direction of the car in the direction of the target floor in preference to other call signals, the exclusive usability is improved, and when the car no longer has a space for passengers, or in an urgent use There is an effect that can go directly in the direction of the target layer in the case of occurrence.

In addition, according to this procedure, there is a possibility that the response to the call to the platform may be delayed, but there is no practical problem in consideration of the frequency of use of the elevator for the private house and the low number of stop floors of the elevator.
