Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator display device, and more particularly to a display device suitable for informing passengers of a non-stop floor, that is, a floor where elevator service is unavailable.

The floor where the corner of the elevator stops is, for example, inside the car, the call button in the operation panel is set to correspond to the floor where it stops.
Passengers also know that the elevator will stop at that floor by pressing the call button and having the response light turn on continuously.

However, in order to change the purpose of the elevator, the non-stop changeover switch can be used to operate the elevator without stopping at a certain floor or a specific floor, such as in an express operation or by eliminating the access of passengers to that floor. may be done. At this time, when pressing the call button for the floor where the stoppage occurred on the above-mentioned driving board, there was no response, and passengers who tried to go to that floor were told that the response light might be out of service. It was inconvenient to think about it, but in the end, the elevator started moving when the button for another floor was pressed, or when another passenger called for a button, and the elevator passed by without stopping at the non-stop floor that the passenger had pressed first. There was no break, and I realized that that floor was a non-stop floor.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator display device that can immediately and reliably notify passengers that the floor of the call button pressed is a non-stop floor.

To achieve this objective, the present invention temporarily lights up a response light corresponding to a non-stop floor when a call button corresponding to a non-stop floor is pressed, but the elevator stops at the floor concerned. If the response light is not malfunctioning due to a burnout or other malfunction, and the response light remains lit until the vehicle stops on that floor, the response light does not stop due to the difference with the display mode of the floor where the vehicle is stopped. It is characterized by displaying that it is a floor.

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

FIG. 1 shows a block diagram of a portion of the elevator control device that particularly performs sequence control.

In the figure, the microprocessor MPU II has bus 1
3, it is connected to the random access memory R, AM15 and the read-only memory 0M17, and further,
It is connected to the PIA 19 for interfacing with the surroundings. P IA 19 is the call button B1 in the car.
~B8 (corresponding to the first to eighth floors in an eight-story building in the example) and the response lights 1 to 8 are connected to the power source (g).

Among the programs stored in the ROM 17, a flowchart of programs related to the present invention is shown in FIG. This program is processed by MPU II at regular intervals. Terminal 21 indicates that the highlight of this program is "non-stop signal processing." Block 23 is to check whether processing has been performed to make the stopped floor a non-stop floor by another program, and depending on the time factor or a signal from a non-stop changeover switch (not shown), it is determined whether a particular floor or an arbitrary When the floor is set as a non-stop floor, the non-stop signal is determined to be present, so if it is "present", the process advances to the next block 25.

In block 25, it becomes a non-stop floor, and it is checked whether the call button for the next floor is pressed. If it is pressed, it is "Yes" and the process goes to the next block 27. It is checked that it is already being processed at the time of the previous processing, and if it is not processed, press "N" to proceed to the next block 29.
Then, one-shot processing is performed to turn on the response light corresponding to the call button for a certain period of time.

With this process, the button will only be lit for a certain period of time after it is pressed. The program then goes to the terminal 31, which is the exit of this program, and ends.

To further explain these using FIGS. 1 and 2, when there is no non-stop floor, the signals of call buttons B1 to B8 are P
A signal that is processed by a call registration program (not shown) and turns on the response lights 1 to 8 is output from the P-worker A19 via the IA19. Therefore, for example, when a non-stop floor changeover switch (not shown) is operated, that signal is also processed by the MPU II, and the non-stop signal becomes 1. - The permanent stop signal processing program 21 immediately went to the terminal 31 and nothing was processed because the non-stop signal was "absent", but since it became "present",
If the call button for the floor that is the non-stop floor is not pressed, it will go to the terminal 31 and nothing will be processed, but if the button is pressed, the lighting process will be executed for a certain period of time as described above. It will be done.

Therefore, when the person presses the button, the response light lights up, so it doesn't mean that the bulb is out, and since it lights up only for a certain period of time, the elevator control device is working normally. It turns out that it's not working due to a malfunction.

Next, another example will be described. The code for this example is:
This is the same as in FIG. 1, but the difference is that in the non-stop signal processing program 21, the response lamp is turned on for a certain period of time, so that it is turned on only while the button is pressed.

In FIG. 3, terminal 41 has the same meaning as terminal 21 in FIG. 2, block 43 is also the same as block 23, and block 45 is also the same as block 25. If the call button is pressed in block 45, go to block 47 with "Yes" and go to block 47 to turn on the response light for that button; if it is not pressed, go to block 49 with "no" and go to block 47 to turn on the response light. Execute the process to turn off the light.

Therefore, in this embodiment, the response light lights up only when it is pressed, so the program is simpler than in the previous embodiment, and depending on the preference of the person who presses it, the response light turns on after a certain period of time. The ability to indicate that the floor is a non-stop floor has also been improved.

Furthermore, other embodiments will be described using FIGS. 4 to 6. FIG. 4 is a block diagram similar to FIG. 1, and the same parts are given the same numbers.

The differences between this diagram and FIG. It is connected to the power supply (G) via the

FIG. 5 is a flowchart of this sequence processing program, but only the portions related to the present invention are shown. The program represented by the terminal 71 is started at regular intervals to perform sequence control of the elevator, but in block 73 of the program, the call button is disabled when the elevator is in maintenance operation or the like. At this time, the coil of relay 61 (not shown) is released by the process of MPUII, and its normally open contact 61. Either open the circuit and remove the power to the call button shown in Figure 4. At the same time, check the signal as the call button signal is set to "invalid".
The next block 75, call registration processing, is not executed.

FIG. 6 is a detailed flowchart of the above call registration process. In block 81, if there is a non-stop signal as in the previous embodiment, the process goes to block 83.
Now, check whether the call button for the non-stop floor is pressed,
If it is pressed, go to terminal 89 without doing anything, and if there is no button pressed, check whether there is a signal from a call button other than the non-stop floor, and if it is, block. 87
Then, a registration process is performed to stop the elevator at that floor, and a process is performed to keep the response light on.

To further explain these as a whole, when the elevator can respond to the call button, contact 61. Since the circuit is closed, there is power for the call buttons B1 to B8, and when the button is pressed, the MP
The response light is turned on along the path (G)-1-Bl-(-) regardless of the UII process. At the same time, the input/output terminal of PIA 19 receives power from (g) to (g) through the response light, so the MPU 11 transfers this from ←) to (g).
It is detected when the button changes to , and the call button signal is set to ``present''. Therefore, the MPU 11 normally registers the call in the block 87, and further outputs the input/output terminal of the P-worker A 19 so as to keep it at (c). This continuation continues until the elevator arrives at that floor.

However, if it is a non-stop floor, no processing is performed in block 83, so the light will not be lit continuously, but will only be lit while the button is pressed.

Furthermore, when disabling the call button, the contact 61° is opened, so even if the call buttons 81 to B8 are pressed, they will not light up, and
Even if the PIA 19 (Hiroyuki Hiromoto) is no longer connected to the input/output terminal of the PIA 19 and the call button is pressed, the call registration process is disabled by block 73, so there will be no malfunction.

In addition, in this embodiment, the lighting process of the program was performed by hardware, so the program was easy and the P.
There is also the advantage that the number of input/output lines entering the IA19 can be halved.

In the above explanation, the call button inside the car was used, but the same effect can be obtained using the call button at the landing.

As explained above, according to the present invention, by lighting the response light, it is indicated that the function is normal, and by not lighting the response light continuously until the response light is stopped at the floor in question. Since the non-stop floor is indicated by the difference from the display mode of the stop floor, which is lit continuously, it is possible to immediately and reliably notify that it is a non-stop floor.
