Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control device for a double-deck elevator, and more particularly to an operation control device for determining the selection of a car to be used in a single-deck operation system.

[0002]

2. Description of the Related Art In order to increase the effective use area in a building, there is a method of reducing the area of a hoistway by adopting a double deck elevator having a car connected vertically.

The following three types of double deck elevators can be roughly classified according to the driving method. The upper car is an even-numbered floor, the lower car is an odd-numbered floor (or vice versa), a double-deck operation method that restricts the service floor, an upper and lower car can be freely serviced to each floor, and one of the upper and lower cars is used. It is a single-deck operation system that is closed and serviced using only one car.

Conventionally, when switching from double deck operation or semi-double deck operation to single deck operation as described in, for example, Japanese Patent No. 840603 or Japanese Patent No. 982177, passengers are erroneously placed in a closed car. There are patents that try to prevent trapping.

As described in Japanese Patent No. 856325, there is a patent in which a lower car responds to a hall call when an elevator rises and an upper car responds when the elevator descends.

Further, in Japanese Patent Application Laid-Open No. 63-123778, an upper dummy floor is provided above a top floor of a building where a double-deck elevator is installed so that a lower car can be serviced. It describes a destination registration method when a lower dummy floor is provided below the lowest floor so that an upper car can be serviced.

[0007] In addition, as for a normal single-deck elevator, Japanese Patent Application Laid-Open No. 62-79172 discloses a method of selecting and deciding a unit to be suspended in order to make each unit wear at the same level. Japanese Patent Laid-Open Publication No. 57-33171 describes that the service floors of the respective units are replaced to make the usage amounts of the respective units approximately the same.

[0008]

A conventional example of Japanese Patent No. 840 is disclosed.
In Japanese Patent No. 603 and Japanese Patent No. 982177, it is not considered whether the upper or lower car is used when switching to the single deck operation.

In Japanese Patent No. 856325, which is a conventional example,
The selection of the upper and lower cars is performed only in the traveling direction, and the past use situation is not considered.

[0010] Japanese Patent Application Laid-Open No. 63-123778 does not consider which of the upper and lower cars is used during single deck operation.

In the conventional examples of JP-A-62-79172 and JP-A-57-33171, no consideration is given to the double deck elevator.

As described above, there is no prior art that takes into account differences in specifications, equipment, performance, design, etc. of upper and lower cars with respect to selection of upper and lower cars during single deck operation.

Further, in the above prior art, no consideration is given to which of the upper and lower cars is used during single deck operation using only one car, and the upper car and the lower car are used equally. Instead, one car may be damaged earlier than the other car, and there is a problem in that maintenance is troublesome.

Therefore, the present invention provides a method of selecting upper and lower cars so that the equipment and the like of the upper and lower cars of the double deck elevator can be effectively used when the equipment and the like of the upper and lower cars are made different for the purpose of cost reduction and improvement of design freedom. The purpose of the present invention is to improve the efficiency of elevator maintenance work and reduce maintenance costs by making the degree of damage to the upper and lower cars of the double deck elevator comparable.

[0015]

Means for Solving the Problems In order to achieve the above object, when performing a single deck operation with a double deck elevator, the specifications, equipment, performance, design, etc. of the upper and lower cars are memorized or the specifications, equipment, performance, design, etc. And the like, and a means for selecting the upper or lower car based on the difference between the stored contents or the set contents is provided.

[0016] The car to be used among the upper and lower cars is switched at predetermined time intervals, such as every other day, or when the traffic demand exceeds a predetermined value. The accumulated records and usage counts of the ones with the least number of uses during operation, the one with the lightest transported weight, the one with the least number of presses of the in-car destination floor registration button, and the one with the least power consumption, were recorded. It is provided with a car selecting means for determining and switching based on a record obtained by taking a difference.

[0017]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an example of a system configuration diagram of the present invention.

One or a plurality of double deck elevators 1 is an upper car 2 which is a car connected vertically.
And a lower car 3. The hall is provided with a hall call button 4 and an operation control device 5 for controlling one or more elevators.

Inside the operation control device 5, a clock means 6,
Measuring means 7 for measuring the use condition, operating method determining means 8,
The car selecting means 9 and the service means 1 which are the main points of the present invention
0 is provided.

The measuring means 7 in the operation control device 5 includes a hall call button 4 provided on each floor every predetermined time and a double-deck elevator car 1 including an upper car 2 and a lower car 3.
, The detected content is received from a car in-store destination floor registration button, a load detection device, and a video detection device such as a video camera, and outputs, for example, a traffic demand amount and transmits information to the driving method determination means 8.

Based on the information, the driving method determining means 8 determines the driving method of the double deck elevator. For example, as shown in FIG. 2 described later, when the traffic demand is large, the double deck driving method (DD driving) is used, when the traffic demand is slightly high, the semi-double deck driving method (SDD driving) is used, and when the traffic demand is small. Is used to select and determine an operation method such as a single deck operation method (SD operation). Here, the double-deck operation system is a system in which the upper floor of the service floor is restricted to an even-numbered floor, and the lower car is restricted to an odd-numbered floor (or vice versa). The single deck operation is a system in which one of the upper and lower cars is closed and service is performed using only one of the cars.

When the double deck operation mode and the semi-double deck operation mode are selected and determined, the double deck operation and the semi-double deck operation are performed respectively.

The present invention is effective when a single deck operation is to be performed in the above selection decision. At this time,
The car selecting means 9 selects one of the upper car and the lower car, and closes the other car. The car selecting means 9 will be described later with reference to FIG.

When the car to be used during single deck operation is determined, the single car is operated using the selected car, and the operation of each car is controlled by the service means 10.

The service means 10 controls the operation of the elevator, such as getting on / off the user, opening / closing doors, running, stopping, etc., according to the double deck operation system, the semi-double deck operation system, and the single deck operation system.

Alternatively, the present invention can be similarly performed by using the clock means 6 as an element for determining the operating method 8 and the car selecting means 9. For example, it is also possible to determine the driving method in advance according to the time zone and switch the driving method at a predetermined time to perform the single deck operation. When changing the driving method, it is conceivable that there is a passenger in the car of the elevator, so there should be no passengers in the car when switching. Therefore, by using a device that detects the presence of a passenger in the car, when the passenger is in the car, the car is not switched, or a device that detects that there is no passenger in the car is provided. This prevents the passengers from being trapped in the car when switching to single deck operation.

In addition to the case of selecting the upper and lower cars when switching from the double deck operation or the semi-double deck operation to the single deck operation, the upper and lower cars are used during the single deck operation method. Obviously, it is also possible to switch the use of.

Next, FIG. 2 shows a flow of the operation executed by the operation control device 5, starting from START 20 and ending with END 31.

In step 21, the upper car 2 the lower car 3 and the hall call button 4
Information from the train, signals from the platform,
The traffic demand is collected using detection means such as video cameras and weight detection devices. The measured traffic demand is represented as dem below.

In step 22, the traffic demand dem
Is larger than the predetermined value X1, the process proceeds to step 23,
Select the double deck operation method. dem is a predetermined value X2
If it is greater than or equal to X1, the process proceeds to step 24,
Select the semi-double deck operation system 24. If it is equal to or less than X2, the process proceeds to step 25, and the single deck operation system is selected.

The gist of the present invention is from step 26 after proceeding to step 25 for performing the single deck operation method.

When the single-deck operation method is determined, the procedure moves to selecting a car. First, at step 26, the car used during the previous single-deck operation is investigated. If the last time the upper car was used, it is decided in step 27 to operate with the lower car. Conversely, if the lower car was used last time, the operation should be performed with the upper car in step 28. To decide. That is, a basket opposite to the one used last time is selected. Next, the car to be used, which has just been determined, is recorded in step 29, and is used as reference data when the next single deck operation is performed.

Then, in step 30, step 2
The driving method determined in 3, 24 or 25 to 29 is instructed to the service means 10 to perform the driving.

However, it is not always the case that the car that was used last time and the car that is opposite are selected. A main object of the present invention is to make upper and lower cars equally damaged. For example, depending on the use environment and the like, there may be a case where the purpose is achieved by using the upper car twice and using the lower car once. For example, the following are conceivable as the car selection rules. Differences in the number of times of use, such as the number of times the number of times of use during single deck operation, the lighter weight of the transport, the number of times the destination floor registration button in the car was pressed, and the one with less power consumption are accumulated and used. Judgment is made based on the records taken.

Also, since the car is used not only during single deck operation, the number of times of use of each car, the weight of transportation, the number of times of use of the car destination floor registration button, etc. during double deck operation or semi-double deck operation. It is also effective to consider including it. In addition, since the cars used on the even and odd floors are fixed during double-deck operation, the coefficient calculated from the characteristics of the tenants used for each floor by the number of people at each floor is used. Use rules, determine the rules of use manually at the discretion of maintenance personnel and building managers, and consider that it will be easily damaged by humidity, moisture, umbrellas, etc. in the event of rain This is also effective for making the degree of damage the same.

Step 21 for measuring traffic demand
The step 22 of comparing the demand amount dem with the demand amount dem can be similarly performed even when the time or the time is measured by the clock means. For example, if the operation system is switched to a double-deck operation system, a semi-double-deck operation system, a single-deck operation system, or the like depending on the time zone, the subsequent flow can be performed in the same manner as in FIG.

For the purpose of equalizing the damage of the upper and lower cars, which is the gist of the present invention, the timing of switching the upper car and the lower car is not limited to switching from double deck operation or semi-double deck operation to single deck operation. It is also possible to reverse the use of the upper and lower cars even during the single deck operation.

In a building where a double-deck elevator is installed, an upper dummy floor is provided above the uppermost floor so that a lower car can be served also on the uppermost floor, and a lower floor below the lowermost floor so that an upper car can be provided also on the lowest floor. May have a lower dummy floor.

It is obvious that the present invention has no problem when applied to a place where an upper dummy floor and a lower dummy floor are provided. If both the upper and lower dummy floors are not provided, it may not be possible to provide direct service to the end floors.In this case, however, as in the case of double deck operation where only the even and odd floors are stopped, Stairs and escalators can be used for the floor and the lowest floor. Thus, in order to achieve the main object of the present invention, that is, the upper car 2 and the lower car 3 have the same degree of damage, even if a dummy floor is provided, it is not provided. Can also be applied essentially independently.

According to one embodiment of the present invention, since the upper and lower cars can be used at substantially the same frequency, the consumption of fluorescent lamps and the like in the car can be substantially equalized, and when replacing one of the fluorescent lamps during maintenance, the other is replaced. Since it is possible to determine that the fluorescent lamp of the car is to be replaced, there is an effect that the fluorescent lamp can be easily replaced.

Further, there is an effect that the upper and lower cars can be simultaneously renovated when the car is renovated.

Further, since the car to be used during single-deck operation is clear, it is possible to turn off the lighting of the car to be closed, which has the effect of saving energy.

In addition, when a clean basket and a dirty basket are mixed, the dirty basket tends to stand out.
If all the cars have the same degree of damage, there is an effect that the tendency can be made to be less noticeable.

If the upper and lower cars are randomly switched during single deck operation, there is a possibility that the car may be carried to a non-service floor if the passenger does not get off for any reason. However, according to the present invention, the car to be used is not randomly switched during the single deck operation, so that there is an effect that the possibility of occurrence of the above-mentioned problem can be reduced. Further, the above-mentioned occurrence probability can be further reduced by interlocking with the notification means, the detector, and the like.

Next, FIG. 3 showing the flow of the operation executed by the operation control device 5 as in FIG. 2 will be described. In this embodiment, another point of the present invention that is substantially different from FIG. 2 is from step 32 after proceeding to step 25 for performing the single-deck operation method.

When the single-deck operation method is determined, the procedure moves to car selection. First, at step 32, a priority car is selected by equipment. If there is a difference in equipment between the upper and lower baskets, select the car with the equipment you want to use. Then, it is determined that the operation is performed by the priority car selected in step 33. When the car to be used is determined, the process proceeds to step 30 in the same manner as in the case of FIG. 2 described above, and operation is performed according to the determined method.

Here, the reason for changing the equipment of the upper and lower cars is to reduce costs, improve the degree of freedom in designing, and reduce the weight of the car in a planned manner. Examples of car selection are that one of the cars has an indicator, a TV monitor or a security camera, is wheelchair-compatible, can use a mobile phone, and has multifunctional lighting. No. Also, not only the selection of priority car by equipment,
It is also possible to select the car to be used depending on the difference between the upper and lower cars such as design and performance. For example, one car has a high ceiling, only one has an observation window,
It is said that it is made sturdy. It is also conceivable to perform repairs or the like within a range that does not affect the other car.

In the above-described embodiment, the upper and lower cars are selected when the mode is switched to the single deck operation mode. However, the priority car may be determined or changed during the single deck operation. .

Another effect of the embodiment of the present invention is that the upper and lower cars can be appropriately selected during single deck operation when different specifications are set for the upper car and the lower car, so that a more effective car can be selected. The use of a simple elevator becomes possible.

Although the above description is directed to a double deck elevator, it is clear that the same can be said when there are three or more cars.

[0052]

According to the present invention, there is an effect that the cost can be reduced, the degree of freedom of design can be improved, the weight of the car can be reduced, and the like can be planned. In addition, the degree of damage to the upper and lower cars is substantially the same, and there is an effect of increasing the efficiency of maintenance work and reducing maintenance costs.
