Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator operating device that controls the standby of an elevator under specific conditions.

[Conventional technology]

Conventionally, in elevators installed outdoors, cars are kept on standby at predetermined floors during times of strong winds or heavy rain. For example, in times of strong winds, it has been proposed to have ropes (particularly convene ropes) wait on the lowest floor to prevent them from getting caught, and during heavy rain, to have them on standby on the top floor to prevent water from breaking as much as possible. Figures 3 to 5 show examples of this, in which the outputs of multiple detectors are divided into multiple steps, priorities are set for each output, and the standby mode corresponds to the output with the highest priority. The system automatically selects a floor, returns to the floor, and waits there.

The conventional example will be explained below with reference to Figs. 3 and 5 = Fig. 3 shows a system configuration diagram of an outdoor elevator operation device, and 21 is a function for controlling the operation of the outdoor elevator and selection of the return floor under external conditions. This control device 21 is equipped with a microprocessor 2.
2 and RO where programs and fixed value data are stored.
It consists of an input device 24 and an output device 25 that interface with the equipment, which is composed of a RAM that stores data such as the calculation results of the microprocessor 722, and these storage devices 23 and input devices. 24. An output device 25 is connected to the microprocessor 22 via a bus 26, and the input device 2 is connected to the microprocessor 22 via a bus 26.
4 is connected to a rain gauge 27 and an anemometer 28 for detecting external conditions of the outdoor elevator, such as weather conditions,
Further, an elevator drive bag W29 is connected to the output device 25.

A rainfall detection signal 27a from the rain gauge 27 is turned on when the rainfall is greater than or equal to AI, AZ (AI<A2).

27b are output respectively, and
From the anemometer 28, the wind speed B is m/sec.

O when B2m/sec (B+ < Bz) or more
Wind speed detection signals 28a and 28b of N are output, respectively.

Next, the operation of the apparatus configured as described above will be explained based on FIGS. 4 and 5. In addition, here, the return during rain,
A case will be described in which the waiting floor (hereinafter simply referred to as the waiting floor) is set as the top floor, and the waiting floor during strong winds is set as the bottom floor. This is because if the waiting floor is on the top floor during rainy weather, the amount of water that will cover the ground will be reduced, and if the waiting floor is on the top floor during strong winds, it will be effective in preventing the convencator rope from getting caught. This is generally considered. Also, rain gauge 27
output signals 27a, 27b, output signal 28 of anemometer 28
The following description assumes that the priority order of a and 28b is determined as shown in the table below.

〔table〕

The reason for setting the priority order as shown in the table above is that outdoor elevators are generally treated with some kind of waterproof or drip-proof treatment, are relatively resistant to rain, and are less dangerous when normal operation resumes. From this point of view, the priority during rain is low, and
This is also based on the idea that a high priority should be given during strong winds to avoid problems with ropes and control cables getting caught, and to improve riding comfort.

Now, during wind and rain, each output signal 27a, 27b, 28a, 28b of the rain gauge 27 and anemometer 28 is shown in FIG.
The cases shown in + to (d) will be explained based on the flowchart of FIG.

When it comes to wind and rain, the control device 21 executes a program shown in FIG. 4 for determining the priority order and instructing the return trip. first,
In step Sl, it is determined whether the output signal 28b of the anemometer 28 is being output. If it is determined that the signal is being output, the process moves to step S9 and flag B is set.

Then, in the next step S10, it is determined whether flag B is still set after a predetermined time, but since the predetermined time has not elapsed, the return and standby command (hereinafter referred to as return command) has not yet been issued. do not have.

Further, when it is determined in step SL that the output signal 28b is not output, the process moves to step S2,
It is determined whether the output signal 27b of the rain gauge 27 is being output. Here, if it is determined that the output is being output, the process moves to step S12 and flag A is set.
Since the cent time is determined in step S13,
As above, no return command is issued.

Similarly, when the determination in step S2 is rNOJ, the process moves to step S3, where it is determined whether the output signal 28a of the anemometer 28 is output, and in step S4, the output signal 27a of the rain gauge 27 is output. It is determined whether or not it is being output, and when the result is rYEsj, the process moves to step 89 or S12, respectively, and continues to set flags B and A, respectively. Here, the predetermined time in step SIO, S13 is shown in FIG. 5Fg). If it is set as rt, as is clear from (e), (f), and (gl) in Fig. 5, flags A and B are reset and reset before the predetermined time '[1] elapses. Therefore, the process does not proceed to the next step Sll or S14, and no return command is issued.The reason for doing this is that instantaneous detection means (rain gauge, rain gauge,
This is to prevent the sensor from immediately following the output signal of the anemometer) and to grasp the phenomenon more reliably.

Therefore, the return command will not be issued during the time period t0 to t1 shown in FIG.

However, at time t2, flag B is set to t.

The flag A is reset at each point in time, and this set state continues even after the predetermined time TI has elapsed.
If it is determined in determination step SIO or S13, respectively, that is, at time t4, flag B is set in step SIO.
When it is determined that is still set after time Tl,
Proceeding to the next step S11, a command to return to the lowest floor is issued, and the elevator returns to the lowest floor and waits.

When the return command for the bottom floor is issued, the return command for the top floor is constrained, so even if it is determined in step S13 that flag A is still set after a predetermined time, the return command for the top floor will not be issued. do not have. Note that, contrary to the above, when the return command for the top floor is issued first, the return command for the bottom floor is more constrained.

On the other hand, once the return command is issued, all conditions to be considered are canceled and normal operation is resumed after a predetermined time T2. This processing procedure is shown in steps 35 to S8.

That is, in step S5, it is determined whether or not a return command has been issued, and when the return command has not been issued, the process directly proceeds to step S8 for returning to normal operation, and when the return command has been issued, the process proceeds to step S6. and output signals 27a, 2
7b, 28a, 28b output = 0 state for a predetermined time T2
, that is, from the time of FIG. 5 (gl paste) to the time of 1h m
Determine whether or not it has continued, and if rYEsJ, proceed to step S.
Proceed to step 7 to return, reset the standby command, and return the elevator to normal operation.

In this embodiment as described above, each output state of the anemometer 28 and the rain gauge 27 is sequentially searched and determined according to a preset priority order, and a return floor command corresponding to the external situation of the outdoor elevator is automatically determined. Therefore, the elevator is properly returned and put on standby depending on the external conditions, that is, the weather conditions.

[Problem that the invention seeks to solve]

Conventional elevator operation equipment is configured as described above, so when a car is placed on standby at the top floor, the elevator cannot be used until the standby condition is lifted, and the elevator is placed on the upper floors of the building. Those who were inside and wanted to get out quickly had to use the stairs to get down. Although this was unavoidable, there was a problem in that even passengers who boarded the car and were about to head to the top floor to wait were left behind on the top floor.

This invention was made to solve the above-mentioned problems.
To provide an elevator operating device that allows a user to choose whether to stay inside a building or go out of the building as soon as possible.

[Means for solving problems]

The elevator operation device according to the present invention causes the elevator to return to the lower waiting floor as is when waiting on the lower waiting floor, and when making the elevator wait on the upper waiting floor, returns to the lower waiting floor once, and then displays a message indicating that the elevator will return and wait at the upper waiting floor. After that, they are made to wait on the upper waiting floor.

[Effect]

The elevator operating device according to the present invention includes a first return command device and a second return command device, and when either an upper floor return/standby command or a lower floor return/standby command (hereinafter referred to as return command) is output, The first return command device causes the vehicle to return to the lower floor once, and if the upper floor return command is not output, it is made to wait at the lower return floor. On the other hand, if the command to return to an upper floor is output, the driver will return to the upper waiting floor and wait there, which will solve the problem of leaving passengers who have boarded the same train on the top floor. .
