Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a jerking control device capable of controlling an elevator to stop without using a key switch in an elevator hall.

[Technical background of the invention]

Conventional methods for stopping elevators include a method in which the control power to the elevator is immediately turned off and the elevator enters a rest state upon a stop command, and a designated floor rest method in which the elevator automatically returns to a predetermined floor by a stop command and then enters the weighing scale. Alternatively, there is an automatic system that obtains a suspension command from a clock device and enters suspension at a predetermined time.

In the other systems except for the automatic stop system mentioned above, a key switch is used to issue a stop command, and this key switch is usually operated by the building manager.

Incidentally, a key switch for issuing the stop command is generally installed on a wall near the elevator entrance of the floor where the elevator is to be stopped. When stopping the elevator, first operate the key switch to call the elevator to the floor where it stops and check the inside of the car.
After confirming that there were no abnormalities, the lights inside the car were turned off and then turned off.

[Problems with background technology]

However, providing a key switch on the wall near the elevator entrance of the parking floor is not desirable in terms of design, so it tends to be disliked. For this reason, in recent years, key switches have been installed in hard-to-see locations away from elevator halls or in control rooms. However, if you do this, if you want to stop the elevator, first operate the key switch to move the elevator to the stop floor, then go to the elevator hall and check the inside of the car, and if there is no abnormality, turn off the lights. Because it is necessary to suspend the
It is unnecessary for the manager or the like to go back and forth between the elevator hall and the key switch installation location, and there is a possibility that problems may occur such as passengers getting on the elevator and relaxing or registering calls during that time.

[Purpose of the invention]

The present invention solves the above-mentioned misalignment, makes it possible to issue a weight command at the elevator hall without using a key switch, and eliminates design problems near the elevator entrance. Another object of the present invention is to provide an elevator parking control device that allows the elevator to be stopped simply and easily.

[Summary of the invention]

In order to achieve such an object, the present invention inputs a coded signal into a microcomputer by operating a hall call registration pushbutton switch in a predetermined procedure on the terminal floor, and this computer converts the code signal into a stop signal. The system determines whether the request is a request or a request to cancel the pause, and then puts the elevator on hold or cancels the pause.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure shows the connection relationship between the control panel installed in the elevator machine room and the call registration display system at each landing. In Fig. 1, 1 is a control panel installed in the elevator machine room, and 2 is a call registration push button switch for ascending and descending, which is installed on the wall near the elevator entrance on each elevator landing floor. The push-button switch 2 has a built-in contact 2a and a display lamp 2b, and the contact 211 and the display lamp 2b are connected to the control panel 1 via a connection line 3, respectively.

FIG. 2 shows the internal configuration of the control panel 1 shown in FIG. 1. In Figure 2, 4 is a microcomputer;
This microcomputer 4 is a calculation control unit (CPU)
5. Write-only memory (RAM) 6. Read-only memory (ROM) 9.

10, an input buffer 7, and an output buffer 8. The RAM 6 registers a hall call signal when a signal from the contact 2a, which is closed by pressing the hall call registration push button switch 2 on the parking floor, is input through the input buffer 7. Also, ROM 9 is the contact point 2 of the hall call registration pushbutton switch 2.
A program for inputting and displaying a call, which is the original function of the input/output of & and the display lamp 2b, is recorded, and a program for performing pause control is recorded in the ROM 10. Furthermore, the CPU 5 reads the hall call signal state registered in the RAM 6 and executes the display program recorded in the ROM 9 and the pause control program recorded in the ROM 10, so that the hall call signal is simply " It determines whether it is a "request to close the landing,""request for pause control," or "cancellation of pause," and lights up, turns off, or blinks the indicator lamp 2b through the exit cover and fa8, and outputs an output (not shown) to the elevator. The signal line allows the train to operate, stop, and cancel the stop.

Next, the operation of the apparatus of this embodiment configured as described above will be described. First, the case of stopping an elevator in operation will be explained with reference to the time chart for the stop operation of the hall call registration push button 6-button switch 2 shown in FIG. 3 and the flowchart of stop control by the microcomputer 4 shown in FIG. do. Now, when the elevator is on a floor other than the main floor, when the hall call registration push button switch 2 of the main floor is pressed and operated, the ON signal of the contact 2a is sent to the RAM through the input buffer 7 of the microcomputer 4.
6, the hall call is registered, and the CPU
5, execution of the display program in the ROM 9 and the pause control program in the ROM 10 is started upon registration of the hall call. First, when a hall call is registered, the display lamp 2b of the pushbutton switch 2 lights up and at the same time, the elevator is called to the landing floor in response. When the elevator arrives at the stop floor, check the inside of the car, turn off the lights, and then press the hall call registration pushbutton switch 2 as shown in Figure 3.
Press and hold for 1 second from this point.

At this time, the pushbutton switch 2 still has a call registration function, so the display lamp 2b is lit. This state is 1
If it continues for a second, the CPU 5 determines the state of the input signal 17, turns off the display lamp 2b at time b in FIG. 3, and then makes it blink at regular intervals (points c, d, and e in the figure).

Here, when the display lamp 2b blinks at regular intervals after time b, the push button switch 2 is operated to switch from the call registration function to the code input for pause control. That is, the push button switch 2 is operated according to a predetermined code (1°0.1) in synchronization with the flashing of the display lamp 2b. In this example, as shown in FIG. 3, push button switch 2 is pressed once at time C,
It shows the timing of not pressing at time d and pressing again at time 6.

When a code signal for pause control is input to the microcomputer 4 through the above operations, the CPU 5 determines from the signal state that it is a request for pause control, and places the elevator in a pause state.

Next, the case of returning the elevator in the +h state will be explained with reference to the time chart for the return operation of the hall call registration pushbutton switch 2 shown in FIG. 4 and the flowchart of return control by the microcomputer 4 shown in FIG. do. Since the elevator is currently inactive, the pushbutton switch 2 does not have a call registration function, and therefore the indicator lamp 2b is also off. To restore the elevator from such a state, first press pushbutton switch 2.
Continue to press for 1 second from point a in Figure 4. In this case, even if the push-button switch 2 is pressed, the display lamp 2b remains off because it does not have a call registration function. When the push button switch 2 is pressed for T seconds, the CPU 5 of the microcomputer 4 determines that this is a request to cancel the pause, and the display lamp 2b of the push button switch 2 is turned on for a predetermined period of time (from point b to C) as in the pause control. (up to this point) lights up to indicate that it has returned to the sleep control state. The display run f2b blinks at constant intervals (points d, @, and f) after time C. Therefore, by operating the push button switch 2 according to the code (i, o, t) in accordance with the flashing of the display run fzb, as in the case of FIG. 3, the microcomputer 1'4
(7) Resume the CPU S technology from the hibernation state, and return the display lamp 2b of the push button switch 2 to the call registration display state.

In this way, in this embodiment, the RO of the microcomputer 4
A display program for call input/output, which is the original function of the hall call registration pushbutton switch 2, is stored in M9, and a ROM I
A pause control program is recorded in O, so that the CPU 5 reads the input signal state by operating the hall call registration push button switch 2, and executes each of the above programs to pause and release the elevator from the paused state. Therefore, there is no need for a key switch dedicated to pausing and resuming the elevator, as was the case in the past. Therefore, not only can the design problem around the elevator entrance/exit date be solved, but also the necessary operation for stopping the elevator at the stop floor can be made simple and easy. Moreover, since there is no need to provide a dedicated pause control circuit, costs can be reduced.

In the above embodiment, the suspension control operation is performed after the elevator is called back to the stopping floor, but the contents of the suspension control may include a command to recall the elevator. In this way, no matter which floor the elevator is on, it can immediately be brought back to the stopping floor and stopped. Furthermore, in the above embodiment, the code for pausing by operating the push button switch was explained as (1, 0, 1).
A configuration may be adopted in which a code different from the pause code can be arbitrarily registered by partially changing the operation method.

By properly using such codes, it becomes possible to control other functions, such as passing through a specific floor, in addition to pausing.

〔Effect of the invention〕

As described above, according to the present invention, the elevator can be paused and released from the pause state simply by operating the hall call registration pushbutton switch in a predetermined procedure. 7. An economically advantageous elevator that does not require a switch and can be easily and easily stopped at the stopping floor.
A 4-King control device can be provided.
