JPS582151B2 - Failure operation device for group control elevators - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a device for operating each car when a group control elevator fails.

A group management elevator is one that is managed as a group of multiple cars.

In this case, each car is operated so as to respond to a car call registered by a destination floor button within the car and a hall call common to each car registered by a hall button.

In this elevator, if the system for registering hall calls and car calls (hereinafter referred to collectively as "calls") breaks down, it will not be possible to detect the calls to be answered, so all cars will operate between the two terminal floors, stopping at each floor. I was trying to do that.

However, in this case, each car takes a long time to make a round, and once a plurality of cars are assembled together, each floor must be stopped in a round-trip operation, resulting in a significantly longer waiting time for each floor and a significant deterioration in operating efficiency.

Therefore, it is conceivable to determine the service floor area of each car so that each car responds only to the floors within its own service floor area.

For example, as shown in Figure 1, the first unit is on the 1st to 4th floors,
Unit No. 3 has the 1st floor and floors 5 to 7 as its operating floors. Unit 3 has the 1st floor and floors 8 to 10 as its service floors, and stops at each floor within its respective service floors.

5th to 10th floors of Unit 1, 2nd to 4th floors and 8th to 10th of Unit 2
The 2nd to 7th floors of Unit 3 are non-commissioned floors, and each car is not put into service on floors within the non-commissioned floors.

In this operation, each unit does not stop on a non-commissioned floor, so
The above problems will be alleviated.

However, for example, if a customer wants to go from the 5th floor to the 10th floor, they must take the second train, get off at the 7th floor, walk to the 8th floor, and from there take the 3rd train to the 10th floor.

Otherwise, you will have to take the second plane to the first floor and then transfer to the third plane.

In this way, it is not possible to go directly from the floor you are on to your destination floor, which is inconvenient.

The present invention aims to improve the above-mentioned problems, and provides a failure operation device for group control elevators that allows each car to go directly from any floor to the destination floor without having to stop at all floors and without changing trains. purpose.

Hereinafter, one embodiment of the present invention will be explained with reference to FIGS. 2 to 5.

In this embodiment, as shown in Fig. 2, 10 floors are divided into floors A1 to A3 for the number of cars (3 cars), and the first car is divided into floor areas A1 (1st to 4th floors) and floors A1 to A3. Area A3 (8th to 10th floors) is an in-service floor, and A2 (5th to 7th floors) is an in-service floor, and for Unit 2, floors A1 and A2 are in-service floors, and floor A3 is a non-in-service floor. For Unit 3, the 1st floor, floors A2 and A3 are in service, and floor A1 (excluding the 1st floor) is in service.

Figures 3 and 4 show the first car. In Figure 3, H is the DC power supply, and 1a to 9a are the calls to the landings on the 1st to 9th floors. There are times when the call registered by the management method is the call that should be answered as is, and there are times when the registered call assigned to the car is the call that should be answered, and these are collectively referred to as calls that should be answered. .

same as below. ), 2b to 10b are contact points for downbound calls from the 2nd to 10th floors, and 10 to 10c are contact points for calls from the 1st to 10th floors when a car call is registered in the first car. Relay contact when closed,
1d to 10d are car position contacts that close when the first car approaches floors 1 to 10, respectively; 11a to 11i are lift operation relay contacts that close when the first car is in lift operation; 12
b~12j are also descending operation relay contacts, 13a~13
g is a normally closed contact of a failure detection device consisting of a relay (not shown) that is always energized and is deenergized when the call system fails; 14 is a stop decision that issues a stop command to the No. 1 machine when energized. The relay 14a is a time-limited relay contact whose normally open contact 15 is closed while the first car is running and opens after a certain period of time has passed after the first car is stopped.

In FIG. 4, 1e to 10e are service floor indicator lights installed at the landings of the first aircraft on the 1st to 10th floors, and when lit, they display, for example, "stop floors 1 to 4, 8 to 10."

Reference numeral 13h designates contacts that operate in the same manner as the failure detection device contacts 13a to 13g in FIG.

In Figure 5, 4e2 is the service floor indicator light installed at the landing of No. 2 aircraft on the 4th floor.
is displayed.

4e3 is the service floor indicator light of the third aircraft, and when lit, it displays, for example, "Stopping floors 1, 5 to 10."

Note that the same indicators as the indicator lights 4e2 and 4e3 are provided at the landings of the second and third cars other than the fourth floor.

Next, the operation of this embodiment will be explained.

If the call system is normal, the fault detection device contacts 13a to 13
h is open.

Assuming that a car call on the 6th floor is registered in the first car, contact 6c closes, and when the car approaches the 6th floor, car position contact 6
d is closed.

Since contact 15 is closed during running, (+)-6c-6
The stop determination relay 14 is energized by the circuit d-14-(-) and self-holds by closing the contact 14a.

As a result, the car stops at the 6th floor and the koji point 6c is opened.

Further, the contact 15 is also opened after a certain period of time, and the relay 14 is deenergized.

The up call to be answered on the 6th floor is registered instead of the 6th floor call, and contacts 6a and 11f are closed during ascending operation, and the down call to be answered on the 6th floor is registered, and in descending operation In this case, the contacts 6b and 12f are closed, and the car stops at the 6th floor in the same way as when the car is called.

The same applies to other floors.

Also, during this time, all the service floor indicator lights of Units 1 to 3 do not light up.

Next, when the call system fails, the failure detection device contact 13a
~13g is closed.

In addition, hall call and car call relay contacts 1a to 9a, 2
b to 10b and 1c to 10e are all open.

Therefore, the circuit connected to the contacts 13a to 13g, that is, stops at the 1st to 4th floors and the 8th to 10th floors, but does not stop at the 5th to 7th floors.

In addition, since the contact 13h is also closed, the indicator lights 1e to 10e
lights up to indicate the floor in service.

Similarly, the second car stops on the 1st to 7th floors, and the third car stops on the 1st floor and the 5th to 10th floors.

In other words, each car will stop at each floor within the service floor indicated by diagonal lines in FIG.

As is clear from Figure 2, customers on each floor can go directly to any floor without changing trains.

For example, to go from the 1st floor to the 9th floor, you can take the first train, to go from the 3rd to the 6th floor, take the second train, and to go from the 10th floor to the 5th floor, you can take the third train.

Furthermore, to go from any floor to the first floor, the user only has to ride the car that arrived earlier among the two cars.

The selection of these cars can be recognized by the service floor indicator light.

For example, a waiting passenger who wants to go to the 10th floor landing on the 4th floor looks at the service floor indicator lights 4e, 4e2, and 4e3 and knows that he should wait at the landing of the 1st car.

In addition, one service floor indicator light 4e, 4e, 4e3 is installed on each floor.
It is also possible to display them all at once.

Further, a non-commissioned floor indicator light may not be provided.

An example in which four or more cars are installed is shown below.

FIG. 6 shows an embodiment of the present invention in which four cars are installed.

In other words, 10 floors are divided into floor areas A1 for the number of cars (4 cars).
- A4, and the first unit has floors A1, (1st to 3rd floors) and floors A4, (8th to 10th floors) as service floors, and the second unit has floors A1 and A2 (4th floor). and 5th floor) as its service floors, Noodle No. 3's service floors are floors A1 to A3, and Unit 4's service floors are the 1st floor and floors A2 to A4. .

With this assumption of floors, it is possible to go directly to the destination floor from any floor.

Similarly, when there are five or more cars, the service floor of each car may be determined by the following procedure, with the number of cars being n and the floors obtained by dividing the total number of floors into n being A1 to An.

Unit 1... Floors A1, An Unit 2... Floors A1, A2 Unit 3... Floors A1 to A3 Unit 4...・Floor A1 to A4 No. n machine...1st floor and b floor A2 to An Figure 7 also shows another embodiment of the present invention, and the number of machines for No. 1 to No. 3 is in service. The floors are set according to the above procedure, and the others are set to specific floors, such as floors with heavy traffic.

FIG. 8 also shows another embodiment, with 3 of the first to third machines.
The service floors for the machines are set according to the above procedure, and the fourth and fifth machines are arbitrarily set, for example, in the lower floors and upper floors.

As described above, when the number of cars is four or more, the service floors may be determined for only three specific cars by the above procedure, and the service floors for other cars may be arbitrarily set.

As is clear from the above embodiments, each floor of the three cars (Nos. 1, 3, and 4 in Fig. 6; the others are Nos. 1 to 3) is different from other cars. It is also set to belong to the service rank of

For example, the second floor in Figure 2 is the service floor for Units 1 and 2,
The 5th floor belongs to the service floor for Units 2 and 3.

As explained above, in the present invention, when a call system malfunctions, the system does not stop at a floor within the planned non-service floor, but instead stops at a floor within the other active floor, and this in-service floor is transferred to each floor. are set so that they also belong to the service ranks of other cars.

As a result, each car can go directly from any floor to the destination floor without stopping at all floors and without changing trains, improving operational efficiency and shortening waiting time.
