Abstract

PURPOSE:To prevent an unpleasant feeling from occurring to passengers in a cage and passengers waiting in a hall by deciding it is a full up condition when a condition there is no space and passengers can get in no more is detected, and passing the elevator such a condition was detected without stopping at the floor of a hall call. CONSTITUTION:By the condition 5 of the hall call transmitted from a hall call button 3, the condition 4 of the cage transmitted front a cage 2, and the condition 8 of the cage load transmitted through a motor controller 6, the door is opened by a unit controller 1 only by the hall call, and after that, when it is detected that the inside of the cage 2 was in the condition of load at a specific value or more, there was no increase of load, and the door was being opened or the door opening button was pushed for a specific time or more, it is decided to be probably in a full up condition. And when a hall call is generated again at the same hall after the elevator startes in such a condition, the elevator is decided to be in a full up condition, and the hall call is ignored giving no reply. When the load is reduced less than a specific value, the full up condition is released. Consequently, an unpleasant feeling of the passengers in the cage 2 and the passengers waiting in the hall owing to a useless operation can be prevented.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to an elevator control device, and in particular improves the operation control when the full condition is not met but there is no passenger space and unnecessary stops occur. Regarding.

(Conventional technology) The conventional technique will be explained with reference to FIG.

It is composed of a single control section 1 and a motor control section 6.

A signal from a load detection device installed at the bottom of the elevator car is input to the motor control 6 via a tail cord. The car load state 8 is transmitted from the motor control section 6 to the single control section 1 .

Conventionally, the single control unit 1 detects whether the car is full based only on the car load state 8 transmitted from the motor control unit 6, and if the car is detected to be full, the car does not respond to a hall call.

(Problem to be solved by the invention) Conventionally, fullness of the elevator is detected only by the load of the elevator, so if there are many light people or heavy clothes, it is possible to still ride if the elevator is determined by the load alone. However, due to lack of space, you may not be able to actually ride it. In that case, since the train is not fully booked, you will have to respond to many useless calls during times when there are many people getting on and off the train. This meaningless stoppage delays the arrival of the passengers in the car at their destination floor, which in turn delays service to the passengers waiting in the hall. Moreover, it causes discomfort to the passengers inside the car and the people waiting in the hall.

An object of the present invention is to detect, without using a special detector, a case in which it is possible to ride a bicycle based only on the load, but it is actually impossible to ride due to lack of space.

[Structure of the invention]

(Means for Solving the Problems) A means for detecting the load condition of an elevator, a means for detecting a non-boarding state when the first hall call is stopped, and determining whether there is no boarding space, and a means for passing the hall call by detecting the condition described above. and configure it.

(Function) If it is detected that it is virtually impossible to board due to lack of space based on the condition inside the car and the detection of no boarding status when the car is stopped at the hall call, it is determined that the car is full and the car passes through the hall call of the car in which it is detected. .

(Example) The configuration of an embodiment of the present invention will be explained with reference to FIG.

It is composed of a single control section 1, a car 2, a hall call button 3, and a motor control section 6.

Car status 4 is sent from car 2 to unit control unit 1 . The contents of car state 4 are door open button state 4A and door open state 4B.
, car call state 4C1, car load detection signal 4D, etc. A landing call status 5 is transmitted from the landing ring bon 3 to the single controller 1. The running state 7 and the car load state 8 are transmitted from the motor control section 6 to the single control section 1 .

Based on the landing call status 5 sent from the landing call button 3, the car status 4 sent from the car status 2, and the car load status 8 sent via the motor control unit 6, the single control unit 1 calls only one landing call. After the door is opened, if the load in the car exceeds a predetermined value and the load does not increase by more than a certain value, and it is detected that the door has been open for a certain period of time or the door open button has been pressed, it is possible that the car is full. I judge it to be sexual. If the same platform call occurs again after the start with the possibility that the car is full, that car will be judged to be full and will ignore the platform call and not respond. What if the load decreases by more than a certain value? 1M member will be canceled.

The full occupancy detection process will be explained with reference to FIG.

If the load inside the car is equal to or higher than the full load, it is determined that the car is full.

When the car is less than full load and is stopped and not full,
Detect if it is likely to be full. This detection method is performed when the car is stopped due to a landing call, and when the load in the car is above a predetermined value and there is no change in the load above a certain level, and
When the door is left open for more than a certain period of time or the door open button is pressed, it is determined that there is a possibility that the car is full, and the car position, floor, and direction are saved as the data of the answered platform call as being in a semi-full state.

If the load in the car is less than the full load, the car is stopped, and the car is full, and the load decreases by a certain value or more, the full load is canceled.

When the car is running with a full load or less, if it is not full and is semi-full, if the same platform call as when the car becomes semi-full within a fixed time after the start, it will be considered full. .

It is possible to reduce meaningless stops in cases where it is possible to ride with just the load, but it is virtually impossible to ride. This will improve our service.

In addition, it is possible to eliminate the discomfort caused by wasteful operation of passengers in the car and those waiting in the hall.

Another embodiment of the present invention will be described with reference to FIG.

It is composed of a group management control section 9, individual control sections 1 and 2, a landing call button 3, and a motor control section 6.

Car status 4 is sent from car 2 to unit control unit 1 . The contents of car state 4 are door open button state 4A and door open state 4B.
, car call status 4C1, car load detector signal 4D, etc. A near-full signal 1 is generated from the single control unit 1 based on the running state 7, car load state 8, and car state 4 transmitted from the motor control unit 6.
1 is transmitted to the group management control section 9. Platform call button 3
The group management control unit 9 determines from the platform call status 5 and the semi-full signal 11 sent from
sent to.

Based on the landing call status 5 transmitted from the landing call button 3, the car status 4 transmitted from the car status 2, and the car load status 8 transmitted via the motor control unit 6, the single control unit 1 determines whether the door can be opened by only the landing call. After opening, if the load in the car exceeds a predetermined value, does not increase by more than a certain load, and it is detected that the door has been open for a certain period of time or the door open button has been pressed, there is a possibility that the car is full. I judge that. If there is a possibility that the station is full, the single control unit 1 transmits a near-full signal 11 to the group management control unit 9. The group management control unit 9 sends a semi-full signal 11, and after the start, the same
When a landing call occurs, it is determined that the car number is full, and a full command 12 is transmitted to the single control unit 1.

In addition, already assigned landing calls that are passing through will be subject to reassignment to other aircraft, and landing calls that occur on the first passing floor will not be subject to review. In the single control unit 1 to which the full house command 12 is sent,
It is determined that the group is full and a full signal 13 is sent to the group management control section 9. When the load decreases by more than a certain value, the single control unit 1 cancels the full capacity state.

The full occupancy detection process will be explained with reference to FIG.

If the load inside the car is equal to or higher than the full load, it is determined that the car is full.

When the car is less than full load and is stopped and not full,
Detect if it is likely to be full. This detection method works when the car is stopped due to a landing call, and there is no change in the load within the car at a predetermined load value or above, and the door has been open for a certain period of time, or the door open button is pressed.
We have determined that there is a possibility that the venue will be full, and will mark it as semi-full. The group management control unit detects that the car is in a semi-full state based on the semi-full signal sent from the single control unit, and saves the car position, floor, and direction as data of the responded landing call.

If the load in the car is less than the full load, the car is stopped, and the car is full, and the load decreases by a certain value or more, the full load is canceled.

In the group management control unit, when the car is running with a load less than full, if the car is not full and is in a semi-full state, within a certain period of time after the start, the same platform call as when the car is in a semi-full state is called. When this occurs, a full occupancy command is sent to the single control unit.

In the single control unit, when a full house command is sent, the room is set to a full house state.

It is possible to reduce meaningless stops in cases where it is possible to ride with just the load, but it is virtually impossible to ride. Furthermore, by not allocating to such a machine, the longevity can be reduced.

This improves the service and eliminates the discomfort caused by wasted driving between passengers in the car and those waiting in the hall. The absolute value of the load state is not limited to this example, but the conditions for determining that the state is the same as the full state when there is no passenger, and the absolute value of the load state is not full, are that the vehicle can be modified within the range where the purpose is the same. is obvious.

〔Effect of the invention〕

It is possible to reduce the number of meaningless stops in cases where it is possible to ride with just the load, but it is virtually impossible to ride due to lack of space. This improves the service and eliminates the discomfort caused by wasted driving between passengers in the car and those waiting in the hall.
