[Detailed Description of the Invention] (a) Description of the Technical Field The present invention relates to an improvement of an elevator control device,
If the gap is small, when the car is running at high speed, the air flow around the car becomes high speed, producing wind noise.

FIG. 1 shows the configuration of a typical single hoistway elevator having one hoistway for one car. The elevator hoistway 1 normally has a rope hole 3 between it and the machine room 2, and an entrance/exit of each floor landing (not shown) that is completely closed while the elevator is running.
From the viewpoint of fire prevention, the hoistway wall 9 has a sealed structure except for the following. The car 4 and the hanging weights 5 are driven by a hoist 6 via a rope 7 to move up and down within the hoistway 1 to transport passengers. 50
is a speed generator directly connected to the rotating shaft of the hoist.

Figure 2 is a sectional view taken along the - line in Figure 1, and shows the passenger car 4.
As the car moves up and down, the air in the hoistway 1 flows in the opposite direction to the movement of the car 4, and the wind speed ωo against the hoistway wall 9 passing beside the car 4 becomes high. For simplicity, let us assume that air is an incompressible fluid.
If the influence of the hanging weight 5 is ignored and a simple calculation is made, the result will be approximately as shown in the following equation (1).

ωo=Sc/S−Sc×ν ……(1) ここで ωo:昇降路壁9に対する乗かご4の側面部の風

ωo=S c /S−S c ×ν ...(1) where ωo: Wind speed of the side surface of the car 4 with respect to the hoistway wall 9 (m/sec) S: Horizontal projected area of the inside of the hoistway 1 ( m 2 ) S c : Horizontal projected area of car 4 (m 2 ) ν : Speed of elevator car 4 (m/sec) Car 4 is moving at speed ν in the opposite direction to the direction of the wind. Therefore, the speed ω of the wind relative to the car 4 is roughly expressed by equation (2).

ω = ωo + ν = S / S - S c × ν ... (2) where ω: Wind speed with respect to the car (m/sec) Recently, it has become necessary to reduce the area S of the elevator hoistway 1 as much as possible in order to make the pill profitable. On the other hand, as buildings become taller, the elevator speed ν increases, and in order to minimize the number of elevators installed in parallel, the cars become larger and the horizontal projected area S c of car 4 increases. There is a strong tendency. This high-speed air flow ω generates air vortices around the car 4, which acts as a kind of piston effect and generates typhoon-like noise (wind noise), causing a great sense of anxiety for passengers. It has become more common to give

In elevator group management control, where multiple elevators are managed as a group, two or more cars are often installed together in the same hoistway, and the wind noise described above does not normally occur, but when the cars are installed together in the same hoistway. When all the cars (usually 2 to 4 cars) travel in the same direction at high speed, the action of the pistons generates significant wind noise, which gives an extremely unpleasant impression to elevator passengers.

In order to prevent the above-mentioned wind noise, it would be sufficient to provide a place for the air to escape, but this is often impossible from an architectural standpoint, and it has been desired to avoid the occurrence by controlling the elevator.

従来上記不具合を解決するために下記のような

Conventionally, the following steps have been taken to solve the above problems.

However, the speed of the car is approximately 150
This becomes a problem when the speed exceeds m/min. When at least one of the cars is running, the speed does not increase and there is no problem. In addition, even when both cars are on a long run, there is no problem if the car is placed first and last in the high speed range and does not restrict the airflow, but when the car reaches the high speed range due to the difference in floors and time at the time of departure, there is no problem. It is difficult to predict whether the cars will run very close together or with a difference of about one floor space, and it requires a complicated control device. The side that prevents parallel running, which is the safe side,
In other words, the number of cases in which departures were to be curtailed had to occur at a higher rate than necessary, reducing the efficiency of group management, leading to long waiting calls, and inconveniencing passengers.

又、同一昇降路内の併走乗かご台数が増加する

Another disadvantage is that as the number of cars running parallel to each other increases in the same hoistway, the circuit becomes complicated.

On the other hand, if the wind speed or wind pressure in the hoistway exceeds a predetermined value, the A detector is installed to detect when this happens, and when all the cars in the same hoistway are moving in the same direction, if the detector operates, a deceleration command is issued to any one car. We have already proposed an elevator control device that is characterized by issuing a forced deceleration command to the nearest floor (hereinafter referred to as the "nearest floor") that can be stopped by normal deceleration. Furthermore, another feature of the invention is that if any one of the cars in the same hoistway is scheduled to stop at the nearest floor, the stop is canceled.

This greatly improves the conventional drawbacks, but
If there is a non-stop driving section without an entrance/exit of a landing called an express zone near a modern large-scale building, which spans several to tens of floors, it is possible to detect the need for wind noise countermeasures within the express zone. However, since the nearest floor is the exit floor of the express train, stopping at the farthest floor may not be effective as a countermeasure against wind noise.

To solve this problem, a detector that emits a signal when the wind speed or wind pressure exceeds a predetermined value when all the cars in the same hoistway are moving in the same direction, and a detector that emits a signal when all the cars in the same hoistway are moving in the same direction There is a technique that includes a speed limiting device that suppresses a predetermined speed of the car to a predetermined speed lower than the rated speed when the detector is activated while the car is traveling in the direction of the car. This will solve most of the problems, but
In the above technology, problems may occur because the "predetermined machine number" is a fixed machine number. for example,
As shown in Figure 3, all the cars installed in the same hoistway are 2~
There are relatively many cases where trains start on the same floor with a difference of 3 seconds and ascend or descend within the express section. In this case, if the "predetermined car" is car a, the speed of the rear car will be suppressed, so there is no problem in allowing cars a and b to separate quickly, but if car b is the specified car, car b will suppress the speed. Then, when the speed was slightly decreasing, it would be caught up by the accelerating machine A,
Wind noise may be generated for several seconds until it is completely overtaken, and may echo inside the car. Trying to avoid this
Increasing the wind speed (or wind pressure) detection sensitivity has the disadvantage of making it more likely to malfunction.

The same problem occurs even in the case shown in FIG. 3 where the following car (car No. a) is running at full speed and catches up with the car (car No. b) which is accelerating.

Xoa~X 15 a, X 0 b~X 15 b are machine a and b, respectively.
It is a car position signal of a car, and is a signal expressed in binary with the base point being the landing position on the lowest floor or a point a predetermined distance (for example, 300 mm) below it, and incrementing by 1 for every 10 mm rise. Therefore, subscript 0 corresponds to the most significant bit, and subscript 15 corresponds to the least significant bit. There are various known methods for obtaining this signal, such as a pulse encoder installed coaxially with the speed generator 50. In reality, it is necessary to correct the slippage of the rope 7 during necessary braking at the terminal floor or at each floor upon landing, and various methods are known.
53 is a comparator that compares the magnitude of two positive inputs I1 and I2, and outputs OUT when I1>I2, the output becomes 1 (high level), and when I1<I2, the output becomes 0 (low level). 57 to 62 are AND gates in which the output OUT is 1 when both inputs I1 and I2 are 1, and 0 otherwise.

During normal running, the cars do not run close together, so there is ample escape for the air pushed away by the cars, and the speed of the airflow on the side of the car is less than 8 m/s even if the elevator's rated speed is 240 m/min. It is generally said that wind noise begins to become a problem when the speed of the car is about 10 m/s or higher, so the operating point of the voltage detection relay 26 (VEL) shown in Fig. 10 should be set to about 8 m/s. If this is done, the voltage detection relay 26 (VEL) will not operate during normal driving.

Now, as shown in Fig. 3, if two cars are running close together and descending, as the speed of the two cars increases or as the two cars approach each other, The wind speed of the airflow on the side of the car increases, and when it exceeds 8m/S, VEL turns ON.

In Figure 9, all elevators are descending.
Both XSDa and XSDb become "1" and output 58
OUT becomes "1", and the output OUT of 58 is "1"
It is becoming. (The output of 57 is 0.) In the example of Fig. 3, the output voltage of 51 (for example +
4.5V) is better than the output voltage of 52 (e.g. +4.3V)
Since it is larger, the output OUT of the not gate 53 is "1" and the output of the not gate 54 is "0". Therefore, among the AND gates 59 to 62, only 59 has both inputs being "1", and the OR gate 55 also has an output of "1" and runs backwards due to the output of the amplifier 63. Inside, relay 65 for machine A is
Turn on. On the other hand, since the output of both 61 and 62 becomes 0, the relay 66 for machine B running ahead is
It's off. Therefore, in the circuit shown in Figure 7 of Unit A, the wind noise countermeasure command relay LS is turned ON by P - LS - VEL - XLS - LS coil - N of other units. As a result, the car stops and the brake contactor BK
It holds itself until it is turned off and interlocks with other machines. As a result, in Fig. 8, the target maximum speed was set to the rated speed (voltage V 1 ) by variable resistor VR 1 for setting the rated speed while the wind noise countermeasure command relay LS was OFF;
When LS turns ON, the operating states of the normally closed contact and normally open contact of the wind noise countermeasure command relay LS shown in Figure 9 are switched, and the rated speed setting variable resistor VR 1 and the speed setting variable resistor VR The voltage set by 2 is changed to V 2 . As a result, the speed of No. A is controlled toward the lower speed target value that has been changed, and it is not able to line up with No. B, which is about to catch up, and there is a difference in maximum speed between No. B, which is another No. Unit A, B
It is possible to prevent parallel running of the No. 1 aircraft at high speed, and the wind speed is 8 m/s.
It starts descending almost as soon as it ascends, and there is no wind noise.

Assuming that it is ascending according to the positional relationship shown in Figure 3, the output of 57 is "1" and the output of 58 is "0" in Figure 10.
Therefore, the outputs of 59 to 61 are "0", the output of 62 is "1", XLSb is turned on, and the speed of the No. B aircraft ascending behind is controlled.

Next, when two vehicles are traveling in opposite directions and pass each other in the middle, the instantaneous wind speed when they pass each other becomes large.
m/S may be exceeded, but it is well known from experience that wind noise is not a practical problem during passing, and in this case forced deceleration is not performed to avoid unnecessary stops. That is, since both 57 and 58 in FIG. 9 become "0", both 65 and 66 (XLSa, XLSb) remain OFF, so that forced deceleration does not occur in FIG. 7.

There are various other methods for detecting the wind speed shown in Figures 5 and 6, such as one based on the Pitot tube principle, and one that converts the wind speed into rotational speed using a propeller or the like, and then converts the wind speed to rotational speed using centrifugal force. There are various possibilities, such as operating at a wind speed higher than the set wind speed.

Fig. 10 is a plan view of a wind pressure detection device that measures wind pressure instead of wind speed and has the same function as the above-mentioned wind speed detection device, and Fig. 11 is a side view of the wind pressure detection device shown in Fig. 10. For example, numeral 32 is a fan-shaped plate made of a lightweight material such as aluminum with one end rounded and bent, numeral 32 is a spring plate using a spring material such as phosphor bronze, and numeral 33 is the spring plate 32 attached with screws 34. A mounting base for attaching the fan-shaped plate 31; 36 is the rotating shaft of the switch portion of the micro switch 37;
Reference numeral 8 denotes a mounting base to which the micro switch 37 is fixed with screws 39. The fan-shaped plate 31 is displaced in the vertical direction against the spring force of the spring plate 32 due to the air flow on the side surface of the car when the car is driven up and down, and the amount of displacement is determined by the wind speed and the spring force.
The structure is such that the contact in the micro switch 37 closes when the wind speed is greater than or equal to S, and can be replaced by the voltage detection relay 26 (VEL) of the wind speed detection device shown in FIG.

In FIG. 4, the wind speed detection device 10 is installed on the roof of the car room of the car 4a, but as shown in FIGS. Also, it is not necessarily necessary to install it on the side facing other cars running alongside, but it can be installed in any position where the airflow on the side of the car can be measured.

(e) Purpose of the Invention As explained above, according to the elevator control device of the present invention, there is no problem even if there are sections such as express zones where it is impossible to decelerate and stop immediately, and the effectiveness is limited by the layout of the building etc. Since the maximum speed of the car is slightly lowered and the target value of the last car running in parallel (that is, the car that is about to catch up) is slightly lowered, the impact on passengers is small and the service for the group as a whole is not degraded. There isn't. As shown in Figure 3, there are cars A and B running side by side in the same hoistway, and even if car B starts on the 18th floor and catches up with car A while accelerating in the express zone, it is definitely close to catching up. The speed of Unit A is suppressed and lowered quickly, so no wind noise is generated.

In addition, a simple control device reliably predicts and prevents the occurrence of wind noise when running side-by-side, so the movement of the cars is unnecessarily restricted, resulting in a sense of anxiety and anxiety among passengers. In addition, the circuit configuration does not become complicated even when a large number of cars run side by side in the same hoistway.
