Abstract

PURPOSE: To easily adjust door opening time by switching opening/closing buttons to an adjusting mode of the door opening time by simultaneously pushing them for a prescribed time, adjusting the door opening time by selecting the opening/closing buttons, and clearing the adjusting mode by simultaneously pushing the opening/closing buttons again after being switched to the adjusting mode. CONSTITUTION: An opening button OB and a closing button CB on a car inside control panel are simultaneously continuously pushed for a prescribed time to be switched to an adjusting mode of door opening time. After they are switched to the adjusting mode, the door opening time is added by pushing the opening button OB, and the door opening time is subtracted by pushing the closing button CB. After they are switched to the adjusting mode, the opening button OB and the closing button CB are simultaneously continuously pushed again for a prescribed time so as to clear the adjusting mode. Thus, the door opening time can be adjusted by a simple method without adding a special operation button and the like.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator door opening time adjusting device.
In particular, the present invention relates to an elevator door opening time adjustment device suitable for buildings where traffic demand fluctuates significantly.

[Conventional technology]

The conventional adjustment of the door opening time of an elevator is, for example, as described in Japanese Patent Application Laid-Open No. 59-22864, by measuring and calculating the actual door opening time in the past, and then adjusting the opening time for the next time the elevator is operated. The most advanced technology was a type of learning control that automatically adjusted the door opening time.

[Problem that the invention seeks to solve]

The above conventional technology adjusts the door open time based on past results. For example, if you want to lengthen the door open time only at a specific time due to the amount of parcels brought in, or if there is an event on a specific floor known in advance. No consideration was given to extending the opening hours of doors on specific floors due to centralized services.

An object of the present invention is to provide an elevator door opening time adjustment device that allows a building manager who is familiar with the building conditions to adjust the door opening time all at once or for each floor using a simple device and method according to the situation. It is about providing.

[Means for solving problems]

The above purpose is to provide a means for switching to the door opening time adjustment mode by pressing and holding the open button and close button on the in-car operation panel at the same time for a predetermined period of time; Door opening time adjustment means that adds the opening time and subtracts the door opening time when the close button is pressed, and erases the adjustment mode by continuing to press the interval button and the close button at the same time again for a predetermined time after switching to the adjustment mode. It was designed to be achieved by configuring the means to do so.

[Effect]

Switching from normal operation to adjustment mode is detected by pressing and holding the open and close buttons at the same time for a predetermined period of time.An indicator light notifies you that the switch has been made, and when switching to adjustment mode, the door closing command circuit is disconnected. , temporarily suspending car operation. At this time, the call registration circuit in the car is also configured to invalidate new registrations while leaving existing registered calls, so that the adjustment operation does not result in wasted calls after normal operation is restored.

Furthermore, even if the vehicle is switched to the adjustment mode due to an erroneous or nuisance operation by a general passenger and left unattended, the system is configured so that a timer automatically restores normal operation after a predetermined period of time. In addition, the adjustment time is configured so that the maximum and minimum values of the counter are set from 1 to 1, so that even if you keep pressing the open or close button, the time within the adjustment range will not be exceeded, and the adjusted time will be indicated by the indicator light. Make it known. Restoration to normal operation after adjustment is done in the same way as switching from normal operation to adjustment mode, simplifying operations for the administrator.

〔Example〕

The present invention will be explained in detail below with reference to the embodiments shown in FIGS. 1, 2, and 4, and FIG. 3.

FIG. 1 is a front view showing one embodiment of the arrangement of indicator lights of the door opening time adjustment device of the present invention, where OB is an open button, CB is a close button, and IC-6C is a destination for the 1st floor to the 6th floor, respectively. The call button, MD is an adjustment mode switching indicator light, and TD is a time indicator light.

FIG. 2 is a circuit diagram showing one embodiment for explaining the present invention in detail, and shows IA, 2A, CA, and ICA.

6CA, IPA, IMA, 6PA, 6MA are AND gates, RR, CR, ICR, 6CR, DR are OR gates,
IT, 2T, 3T, and 4T are timers.

MM, CM, ICM, and 6CM are memories, and when a signal is input to the - side of the S side, the stored signal is stored, and when a signal is input to the R side, the stored signal is erased. IDC and 6DC are timer counters, and their operation is as shown in Figure 3(a).When a continuous signal is applied to the (+) or (-) terminal, a pulse is generated at a period of, for example, 1 second, and the number of pulses is Add or subtract , and set the count-up timer time. Further, the maximum and minimum time limits are configured to be set in advance, and once the addition/subtraction based on the number of pulses reaches the maximum or minimum time, no further progress is made. The added and subtracted times are then output to the terminal. On the other hand, when a signal is input to terminal T from the timer count start command circuit (not shown, but it generates a start signal to timer call 1 when the door is fully opened), the timer starts counting, and the above When the set time is reached, it is output to terminal O.

FIG. 4 is a circuit diagram showing an embodiment of the part related to the normal operation adjustment mode of the present invention, where IF is a signal contact when the car is stopped on the 1st floor, and 6F is a signal contact when the car is stopped on the 6th floor. contact, I
CY is the 1st floor car destination call registration relay, I CY a is its normally open contact, 6CY is the 6th floor car destination call registration relay, 6 CY a is its normally open contact, H is the normally open contact, indicates a normally closed contact, IDC, 6DC, and MM indicate a normally open contact and normally open contact of the timer counter and memory in Fig. 2, respectively, and IG and 6C indicate a normally closed contact on the first floor and 6 in Fig. 1.
This is the floor call button.

Next, the operation will be explained with reference to FIGS. 2 and 4.

First, to switch to the adjustment mode, when both the open button OB and the close button CB are pressed, the AND gate IA outputs an output and the timer IT (a timer of about 3 seconds) starts counting. If you continue to press the button, the timer IT will count up and the memory MM will operate and hold the button. The adjustment mode switching indicator lamp MD lights up in response to the signal from the memory MM, indicating that the adjustment mode has been switched.

Next, for example, if you press the 6th floor destination call button 6C, AND
Gate 6CA outputs and OR gate 6CR.

CR outputs and memories 6CM and CM operate and hold. Next, for example, if you press the open button OB, the open button ○
The AND gate 6PA outputs an output based on the signals from B and the memory 6CM, a signal is applied to the (+) terminal of the timer counter 60C, and the time is added up. When you release the open button OB, the AND gate 6PA stops outputting at that point.
Addition also stops.

Similarly, when the close button CB is pressed, the AND gate 6MA outputs an output, a signal is applied to the (-) terminal of the timer counter 6DC, and the time is subtracted. This time is output from the D terminal of the timer counter 6DC, and the OR gate D
R is output and displayed on the time indicator TD. The operator only has to look at this indicator light TD (digital type) and stop operating the buttons when the desired time is reached. Next, if you want to adjust all floors at once, you can press the open button or close button CB without pressing the destination call button after switching to the adjustment mode. In this operation, two timers (approximately 2 second timers) count based on the signal from the memory MM, and output after a predetermined period of time. Since neither the 1st floor destination call button IC nor the 26th floor destination call button 6C is pressed, the memory C
M is not working. With these two conditions, AND gate C
A is the output, and the Q mark at the input part of the AND gate DCA means that the input signal is inverted, and is the input information that there is no signal of the memory CM), OR gate ICR, SC
Also outputs R, memory ICM.

It also works and holds 6CM. If the open button OB or the close button CB is pressed, the timer counters IDC and 6DC start adding and subtracting all at once, as explained above.
It is displayed on the time indicator TD.

That is, they are adjusted all at once with a delay of the timer 2T.

When the adjustment is complete and you want to restore normal operation, press the pause button OB and close button CB again at the same time to open the AND gate I.
A outputs and AND game 1 is generated by the signal of memory MM.
-2A output, timer 3T (approximately 1 second timer)
counts and operates after a predetermined time. Note that when the open button OB and the close button CB are pressed at the same time, the timer counters IDC and 6DC are applied to both (+) and (-), so they are canceled and the time is not added or subtracted. Due to the operation of timer 3T, OR gate RR outputs, all memories that were operating by applying voltage to the R terminals of memories MM, CM, ICM, and 6CM are erased, and the adjustment mode switching indicator MD also turns off and normal operation resumes. I can see that it has been restored.

In addition, if memory MM is left in operation without performing the next operation, timer 4T (approximately 900 seconds) starts counting based on the signal from memory MM, and when run 1 ends, OR gate RR outputs, Erase all memory and restore normal operation.

Next, the regulation of the normal operation circuit in the adjustment mode will be explained. The door closing command circuit is disconnected by the memory MM, preventing the door from automatically closing, and preventing the car from operating in response to a call. Further, the button input section of the car destination floor call registration circuit is separated by the memory MM so that the call is not registered even if the destination button is operated when adjusting the specific floor opening time. Of course, the holding circuit is not disconnected so that registered calls will not be deleted.

〔Effect of the invention〕

According to the present invention described above, it is possible to adjust the door opening time for all floors simultaneously or for each floor in a simple manner without adding any special operation buttons. This has the effect of making it possible to respond according to the situation.
