Description

Description: TECHNICAL FIELD The present invention relates to an elevator car position display method and apparatus for displaying the position of an elevator car to a user.

[Conventional technology]

Conventionally, the display of the elevator car position is performed in synchronization with the actual car position, and the current position of the car is displayed. Then, the current position of the car is displayed on the floor indicator of each floor and the indicator in the car at the same time.

[Problems to be solved by the invention]

However, in the above-described related art, no consideration is given to the possibility of stopping merely by simply displaying the current position of the car, and the car expected to stop may not stop. For example, if the car is currently on the second floor and is moving in the ascending direction, and the passenger on the third floor presses the call button to go up, the speed of the car is low and the car is in a position where it can be stopped. Can stop on the third floor, but not when the car speed is high. So the car is 3
The result is that passengers on the floor ignore the passengers and pass through, ignoring passengers on the floor.

Further, the user on the third floor thinks that the elevator is out of order, and may use the stairs without using the elevator or contact the management company for the elevator.

The same is true for cars. For example,
If the passenger does not press the destination button immediately and pushes the button after a while, and the speed of the car is fast, the car can not stop on that floor and passes Sometimes.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an elevator car position display method and apparatus which can display the correct driving information of the car to avoid causing confusion to the user.

[Means for solving the problem]

In order to achieve the above object, according to the present invention, among the floor indicators provided on each floor and indicating the position of the car, the floor indicator of the floor on which the preceding position of the car has passed displays the preceding position of the car. Then, the floor at which the preceding position of the car is to arrive and the floor indicator of the floor at which the current position of the car has passed indicate the current position of the car.

In addition, the present invention, among the indicators provided in the car and indicating the position of the car, displays the indicator of the floor where the preceding position of the car will arrive, the display of the floor where the preceding position of the car has passed It can be displayed in a display format different from the indicator.

Further, the present invention provides an elevator car position display device that detects the current position of a car and displays the position of the car to passengers on each floor based on the detection result. A calculating means for calculating the leading position of the car is provided, and the calculation result from the calculating means is input, and the leading position of the car is displayed on the floor indicator of the floor where the leading position of the car has passed, A display means for displaying the current position of the car is provided on the floor at which the preceding position of the car will arrive and the floor indicator of the floor on which the current position of the car has passed.

The present invention also provides an elevator car position display device that detects the current position of a car and displays the position of the car to passengers in the car based on the detection result. A calculation means for calculating the leading position of the car is provided, and the calculation result from the calculating means is input, and the display of the indicator of the floor where the leading position of the car will arrive will pass the leading position of the car. Display means having a display format different from that of the floor indicator.

[Action]

The preceding position of the car indicates a floor that can be stopped and that has advanced ahead of the current position along the traveling direction of the car.
Therefore, if the preceding position of the car is displayed on the floor indicator of the floor between the current position and the preceding position of the car, the user thinks that the car has passed and does not expect to stop.

Also, if the indicator in the car also changes the expression form between the floor where the preceding position arrives and the floor where the preceding position has passed, the passenger can know in advance the floor that can be stopped, There is no button on the floor that cannot be stopped because the speed of the car is fast.

〔Example〕

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

FIG. 1 shows the overall configuration of the elevator system. In the figure, a car 1 and a counter weight 2 of an elevator are connected by a rope 3, and an intermediate portion of the rope 3 is supported by a sheave 4, and the car 1 and the counter weight 2 of the elevator are suspended like a sword. I have. The sheave 4 is driven by a motor 5 via a speed reducer. The motor 5 is supplied with power from a speed control mechanism 6 and a power conversion mechanism 7 and is controlled to a predetermined rotation speed. The speed control mechanism 6 is directly connected to the electric motor 5 to detect the speed and position of the car 1, a position detection mechanism 9 that counts the output of the pulse generator 8 to determine the position of the car 1, and a sequence control. Using the output from the mechanism 10,
The car 1 is stopped at a predetermined position.

The sequence control mechanism 10 includes a position detection mechanism 9, a preceding position detection mechanism 11, call buttons 12 and 13 installed on the floor,
The output from the destination button 17 installed in the car 1 is used to determine the floor on which the car 1 stops, and the position of the car 1 is indicated by a floor indicator installed on each floor.
14, 15 and car indicator 1 installed in car 1
6 is turned on, and various control information is transmitted to the speed control mechanism 6.

FIG. 2 shows one of the processes in the sequence control mechanism 10. The flow which displays the position of a car is shown.
The car position display process 100 is a process included in the sequence control mechanism 10 and is started at regular intervals (sequence cycle).
Step 11 to determine whether the elevator is running
0, if the vehicle is traveling, a step 120 for repeating the processing of steps 130 to 160 by the number of floors, a step 130 for determining whether or not the preceding position has passed the floor on which the floor indicator 14 is to be displayed, Step 140 in which the floor of the preceding position determined by the preceding position detecting mechanism 11 is displayed on the floor indicator 14 if the preceding position has passed, and the floor position determined by the position detecting mechanism 9 if the preceding position has not passed. Step 15 to output to 14
0, determining whether or not the display of the floor indicators 14 and 15 of all floors has ended, and returning to step 120 if the display has not ended, and step 160, and if the elevator is not running That is, when the vehicle is stopped, a step 170 for displaying the stopped floor, which is the output of the position detecting mechanism 9, on all the floor indicators 14 and 15 is constituted.

Next, the operation of the above elevator will be described with reference to FIG. 3 while comparing with the conventional example.

FIG. 3 (a) shows a conventional display method. It is assumed that the elevator car 1 is on the second floor and is traveling in the ascending direction. Conventionally, the floor indicators 14 and 15 indicate the current position of the car 1, and all indicate the second floor. At this time, it is assumed that the speed of the elevator car 1 is so high that the vehicle cannot be stopped on the third floor and the preceding position indicates the fourth floor.

When the passenger arrives on the third floor and the elevator is moving in the ascending direction on the second floor, when the floor indicator 15 is viewed and the call button 13 in the upward direction is pressed, the preceding position is actually moved to the fourth floor. Therefore, he cannot stop on the third floor and ignores the call. For this reason, the passengers feel that they have been betrayed by the elevator.

On the other hand, according to the present embodiment, as shown in FIG. 3B, when the passenger arrives, the floor indicator 1
4 and 15 indicate the fourth floor when the third floor has passed the preceding position, and the fourth floor where the preceding position has not passed indicates the second floor which is the current row position of the elevator car 1.

In this way, passengers on the third floor think that the elevator has passed and do not expect to stop on the third floor.

Although the display is on the fourth floor, when the preceding position is on the fourth floor, the display is not set to the fourth floor of the preceding position. For example, when the next stop is on the fourth floor, the preceding position is locked on the fourth floor, Since car 1 is on the 4th floor as soon as it is on the 2nd floor, if it is displayed at the preceding position, passengers on the 4th floor will have the illusion that a long time has elapsed from approaching the 4th floor to stopping. , To prevent it.

Further, in FIG. 3 (b), when the preceding position shifts from the fourth floor to the fifth floor, the display of the floor indicator 14 is not changed to the fifth floor at once, but is delayed in the order of 2 → 3 → 4 → 5. , And the display in the car 1 can be set to the preceding position.

 Another embodiment of the present invention will be described with reference to FIG.

In the conventional elevator, the indicator 16 of the car 1 displays the car 1 of the elevator, which is the output of the position detection mechanism 9, in order not to give the passenger unnaturalness.

However, a button 17 on the floor where the passenger wishes to stop
In some cases, if the speed of the car 1 is high when the user pushes the button, the car 1 cannot stop on that floor. Therefore, in such a case, the processing flow shown in FIG. 4 is started. The in-car display processing step 200 of the activated processing includes a step 210 for determining whether or not the preceding position of the floor pushed by the passenger has passed, and if the preceding position has passed, the speed is not at the current elevator speed. Step 22 of outputting from the output device provided in the car 1 that the vehicle cannot be stopped because it is too fast.
0.

With this configuration, the passengers in the car do not feel the gap between the elevator position and the floor at which the elevator can be stopped, thereby providing a comfortable elevator for the user.

In addition, as the output device shown in the present embodiment, a voice synthesizer, a CRT display, or the like can be considered.

Furthermore, for elevators that do not have a CRT or voice synthesizer, the floor that can be stopped (the floor where the preceding position does not pass) is dimly lit, and the preceding floor is changed by changing the brightness of the indicator. A method such as display is conceivable. Hereinafter, this will be described with reference to FIG.

FIG. 5 (a) shows a display state of an indicator installed in the car 1 and indicating a car position of the elevator. The indicator 20 of the elevator car 1 turns on the lamp 21 on the sixth floor when the actual position of the elevator is on the sixth floor. Here, the lamps that are turned on are represented by oblique lines.
If the elevator car 1 is in the descending direction,
The downward lamp 22 is turned on.

FIG. 5 (b) shows a display state of the floor indicator 23 on the fifth floor where the preceding position has passed. Assuming that the preceding position is on the fourth floor, the lamp 24 on the fourth floor is turned on, and the lamps indicating the other floors are turned off. FIG. 5C illustrates the state of the call button of the car 1. Here, the first floor, second floor, 3
On the fourth and fourth floor call buttons 25, 26, 27 and 28, the number part lights up,
It indicates that the elevator call generated in the elevator car 1 can be accepted, and the hatched portion of the call button 25 on the first floor indicates that the number background is lit, indicating that the call has been registered. ing. Note that the call buttons on the fifth and sixth floors cannot be stopped because the numbers do not light.

FIG. 5 (d) shows an example of the call button at this time, which is composed of a lamp 30 of the numeral portion and a lamp 31 illuminating the background. Driving these lamps 30, 31 is the fifth
This is the microcomputer 32 shown in FIG. When the lamps 30 and 31 are, for example, light emitting diodes, the lamps 31 and 32 emit light when a current is supplied from the microcomputer 32, and the lamps 31 and 32 when the current is stopped.
32 goes out. Here, when the driving power of the microcomputer is insufficient, it can be realized by adding a driver circuit.

On the other hand, in a port-type elevator that pushes the destination call button before passengers get on the floor side and waits for the arrival of the elevator,
The indicator 20 in the car and the call buttons 25 to 28 installed on the car 1 are installed on the floor side. In this case, the floor side can be realized by providing the same environment as the car 1 of the elevator.

Further, in the case of the port type, a call button provided in a normal elevator is used, and the indicator is lit in a display state as shown in FIG. , And the other floors are lit in a display state as shown in FIG.

In this case, two types of light-emitting diodes are prepared as lamps, indicating that stoppage is possible and that stoppage is accepted. However, one lamp has two types of lighting and blinking. Information can also be shown.

〔The invention's effect〕

As described above, according to the present invention, the indicator on the floor side of the elevator and the indicator in the car always display the floor on which the vehicle can be stopped. The inconvenience that the vehicle does not stop immediately can be prevented, and the elevator becomes very easy for the user to use.
