Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement to an elevator operating device.

Conventionally, when the load in a stopped car becomes full, in order to increase service to that floor, another car is assigned to that floor or the band that includes that floor, or a car scheduled to pass through that floor is stopped. I was doing a lot of things.

However, if you wait until the car is full before another car is serviced to that floor, the hall may already be overflowing with passengers, slowing down service to that floor and degrading the service. . This invention solves the above-mentioned drawbacks. By predicting the final car load of a stopped car at an early stage, it is possible to prevent a decline in service on that floor and improve the overall operating efficiency of the elevator. The purpose of the present invention is to provide an elevator operating device that provides the following features.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Figure 1 is an example showing the relationship between the car load and the degree of change in the car load over time when passengers board the car and the final car load is 80% of the capacity. The degree of change is expressed as a differential value (for example, a voltage value).

Note that the differential values obtained from this relationship are set as reference values, and when the car load is 30%, 40%, and 50% of the capacity, the corresponding reference values are set to V, , V2, and V3, respectively. In addition, Fig. 1 shows the change curve of the differential value when the car load is 80%, but this is normally the case when the car load is 0 and the car load is 100%.
In consideration of the fact that passengers often stop boarding before the car load reaches 80%, the final load is set at 80%. In Figures 2 and 3, E, (10) and (1) are DC power supplies, C is a smoothing capacitor, R, , R2 are resistors, D is a differential circuit, W5 is 5% car load, W, O is an in-car load detection contact that detects in 5% increments such as 10% in-car load, and W is an in-car load detection contact that opens at 50% in-car load.
W3oa to W5oa are 30%, 40%, 50% respectively
In-car load detection contacts that close due to in-car load, 1 to 3 are reference values V corresponding to 30%, 40%, and 50% in-car load
, 10V20V3 or more, the voltage relay is energized.
a to 3a are normally open contacts; 4 to 6 are in-car load memory relays; 4a, 4b to 6a, and 6b are normally open contacts; 7a is the normally open contact; 8 is the travel relay contact that is open when the car is running and open when the car is stopped; 9 is the support relay for the pond unit that opens when support for that floor of another car is determined. This is the final relay contact point.Now, when the car reaches a certain floor, it is assumed that the car is empty, and the hall is filled with people ranging from half the capacity (50% car load) to less than 80% car load. Assume that there are approximately 60% passengers at full capacity (60% load in the car).

When these passengers board the car, the time from the car load 5% detection contact W3 to the car load 40% detection contact W2 is closed quickly because the passengers board the car one after another. Therefore, since the input voltage applied to the differentiating circuit D rises quickly, the output of the differentiating circuit D is likely to be equal to or higher than the reference value V when the in-car load Z is 30%. If the above condition occurs, "at the same time, the in-car load 3o% detection contact W3 is closed," the voltage relay 1 is energized, and its contact ia is closed, so "(10)-8-1a- The memory relay 4 is energized Z by the circuit 4-(-), and self-holds by closing its contact 4a.
When the load inside the car is 40%, the output of the differential circuit D is the reference value V.
The possibility of 2 or more is that the hall passenger is 50% of the car load.
~60% is quite small, but if it exceeds 40% in-car load detection contact W4. a is closed, voltage relay 2 is energized, and its contact 2a is closed, so (
10) Memory relay 5 by the circuit of -8-2a-5-(1)
is energized and maintains itself by closing its contact 5a.
Since there are only a few passengers left in the hall, the input voltage applied to the differential circuit D gradually increases slowly, so when the car load reaches 50%, the car load 50% detection contact W5
Even if oa is closed, the output of the differential circuit D is less than the reference value V3, so the voltage relay 3 is not energized, and the support relay 7 is not energized either. Therefore, it is predicted that this car will not reach 80% of its capacity, and no support operation will be performed. However,
Suppose that there are so many passengers waiting in the hall that one car cannot serve them.

As mentioned above, the memory relay 4 is energized when the car content is 30%,
The memory relay 5 is activated when the car load is 40%. When the load inside the car reaches 50%, the input voltage applied to the differentiating circuit D rises quickly, so the output of the differentiating circuit becomes equal to or higher than the reference value V3, and the voltage relay 3 is energized, and its contact 3a
is closed, the memory relay 6 is energized by the circuit (10)-8-3a-6-(1), and is self-held by opening the contact 6a. Similarly, since the contacts 4b to 6b of the memory relay are also closed, the support relay 7 is energized by the circuit (10)1914b-5b-6b171(1), and the opening of the contact 7a causes the maintain self. By energizing the support relay 7, this floor receives priority service. (Since this operation is well known, the explanation will be omitted.) In the embodiment, the in-cage load is detected every 5%, but it is also possible to detect it more precisely. Also, the support operation is performed at 50% load in the car.
It is also possible to do it sooner. As explained above, this invention detects the degree of change in the car load over time, predicts the final car load at an early stage, and supports other cars as soon as it is detected that the floor is crowded. This prevents a drop in service on that floor and improves overall operational efficiency.
