Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a double-deck elevator in which two cabs are connected at the top and the bottom.

[0002]

2. Description of the Related Art Conventionally, an elevator that operates by connecting two cage rooms vertically is called a double deck elevator. This double-deck elevator generally has an upper car room (hereinafter referred to as the upper car) for even floor calls and a lower car room (hereinafter referred to as the lower car) for odd floor calls. It uses a driving method that allows it to be serviced (this is called double driving). This double operation can be used like a general elevator for passengers going from even floor to even floor or from odd floor to odd floor, but passengers going from even floor to odd floor, and from odd floor to even floor, It is inconvenient for the user because it is necessary to go up and down only the first floor using the stairs.

Therefore, such driving is applied during peak hours such as at work and during lunch, and in other time zones, the operation called semi-double driving is performed. This semi-double operation means passengers who go to even floors and odd floors only on the departure standard floor are divided into upper and lower cars and boarded, and after departure from the departure standard floor, it is optional with upper and lower cars It is a driving that can be stopped on the floor. This semi-double operation is
Since passengers can move directly to any floor, it is easy to use, but the driving efficiency is lower than in double driving.

As described above, the operation of the double-deck elevator is performed by switching between the double operation and the semi-double operation described above every time period. In this situation,
For the purpose of improving the operating efficiency in semi-double operation, which occupies most of the day, when there is a landing call on the upper floor above the departure standard floor, the upper and lower cages of multiple double-deck elevators are set independently. Evaluate independently and select the target car of the best car as the car of the response car, and assign the hall calls without restrictions such as the upper car on the even floors and the lower car on the odd floors like double operation Controls are performed to improve operating efficiency.

[0005]

However, in the above hall call assignment control in the conventional semi-double operation,
Similar to the normal group control of single-deck elevators, the expected arrival time is calculated as an indicator of how well the upper and lower cars of each unit can respond to any floor.
Based on the estimated arrival time to the floor to which the allocation is to be made or the floor to which the own machine is already scheduled to respond, a predetermined evaluation calculation is performed and the car of the best car is selected.

However, focusing on the same machine, unlike the normal single-deck elevator, because it has an upper and lower car structure, if one car has a response plan, the other car has no response plan. Must also be stopped, and the passengers in the other car will generally wait in the door closed state until the loading and unloading of one car is completed. This waiting time is hereinafter referred to as the waiting time. In particular, as the number of passengers in the car increases, this state occurs a plurality of times before reaching the destination floor, which causes discomfort to the passengers every time the car stops.

As described above, in the conventional allocation control system in which the estimated arrival time is used as the basis of the evaluation calculation, only the service of waiting passengers at the landing is considered, so that the callless stop easily occurs and the passengers in the car are made to wait. There was a problem.

Therefore, the present invention has been made to solve the above problems, and in semi-double operation, the allocation evaluation index is used as the waiting time for waiting passengers (estimated arrival time).
Another object of the present invention is to provide a control device for a double-deck elevator that averages the service for passengers waiting in the hall and the service for passengers in the car in consideration of the waiting time of the passengers in the car due to the call stop.

[0021]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram showing a first embodiment of a control device for a double deck elevator according to the present invention.
It is assumed that two double deck elevators are installed in a 12-story building. In FIG.
Reference numerals 1 and 2 denote car control devices for the first and second cars, respectively. The car control device 1 responds to the hall call received from the group management control device 5 described later, and responds to this by the group management control. Well-known hall call response means 1 for instructing the device 5
-1, well-known operation control means 1-2 for controlling running and stopping of the upper and lower cars, well-known driving direction control means 1-3 for deciding the traveling direction of the upper and lower cars, upper car room (upper car ) And a well-known car call registration means 1-5 for controlling the car calls of the upper car room and the lower car room respectively. Has been done. The car control device 2 of the second car is also constructed in the same manner as the first car.

Further, the group management control device 5 has well-known hall call registration means 5-1 for controlling registration of hall calls 6-1 to 6-12 provided on each floor, and hall calls 6-1 to 6-12. On the other hand, the allocation control means 5-2 performs allocation evaluation calculation depending on the states of the first and second machines.

Further, 3U, 3L and 4U, 4L are the upper and lower cages of the first and second machines, respectively. Next, the operation of the control device for the double-deck elevator having such a configuration will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation of the allocation control means 5-2 of the group management control device 5, and FIG. 3 shows an example of the state of the elevator for explaining the operation.

The operation of the allocation control means 5-2 according to the present invention will be described with reference to the case of FIG. In Fig. 3, Unit 1 is traveling on the 3rd and 4th floors in order to respond to the car call registered in the upper car on the 6th floor and the lower car on the 7th floor. It is about to leave the 1st and 2nd floors by calling the car in the lower floor car. In such a situation, when a hall call for the ninth floor occurs, the expected arrival time of the upper car or the lower car to any floor is calculated in the current state. The estimated arrival time is
Prediction caused by upward / downward landing calls, obtained by adding the time required to travel (travel time) from the distance between the current car position and the target floor and the time required to stop from the number of stops on the intermediate floor It is general to calculate the judgment floor on the assumption that a car call occurs at a predetermined position as a car call (hereinafter referred to as a derived car call).

In the example shown in FIG. 3, 9 cars in the first car
Assuming that the estimated arrival time to the upper floor is 2 seconds per floor as the travel time and the stop time is 10 seconds, the 6th, 5th floor and 8th, 7th
(2 × 2) +10+ to respond to the 9th and 8th floors after the floor stops
(2 x 2) + 10 + (2 x 1) = 30 seconds, which is the predicted unanswered time T1U, which is the sum of the call duration and the predicted arrival time.
(9U) is 30 + 0 = 30 seconds. Similarly, the predicted non-response time T1L (9U) of the lower car of Unit 1 is 32 seconds.

Next, assuming that the upper car on the 9th floor, which is the target floor, is assigned to the upper car of the first car, the predicted arrival time of the upper car of the first car is the current one because there is no other hall call already allocated. It becomes 30 seconds like the state, and the predicted unresponsive time T1UU
(9U) is 30 seconds.

Next, assuming that the upper car of the ninth floor, which is the target floor, is allocated to the lower car of Unit 1, the predicted unanswered time T1LL (9U) of the lower car is 32 because there is no other hall call already allocated. Seconds.

Next, assuming that the upper car of the first car is assigned the upper floor call of the ninth floor, which is the target floor, the fourth floor to the third floor,
It is only once on the 6th and 5th floors that there will be passengers in the upper car that will be answered (has a call) and there will be no passengers in the lower car (has no call) before leaving the 8th floor. The waiting time T1UW (9U) for passengers in the lower car is 10 seconds.
Assuming that the upper car on the 9th floor, which is the target floor, is assigned to the lower car of Unit 1, there is a call on the lower car and no call on the upper car by the time you depart from floors 4 and 3 to floors 9 and 8. Although it stops once on the 8th and 7th floors, there are no passengers in the upper car, so the waiting time T1LW for passengers in the upper car is 0 seconds.

For Unit 2, the same calculation as above is performed, and the predicted unresponsive time in the upward direction of the upper car 9th floor of Unit 2 in the current state T2U (9U) = 24 seconds Upper 9th floor of the lower car of Unit 2 in the current state Predicted unanswered time T2L (9U) = 26 seconds Predicted unanswered time when the upper car of Unit 2 is provisionally assigned to the upper floor on the 9th floor T2UU (9U) = 24 seconds Upper car of Unit 2 on the 9th floor Predicted non-response time when T is tentatively allocated T2LL (9U) = 26 seconds. In addition, the waiting time for the lower car passengers when the upper car of Unit 2 is provisionally allocated to the upper floor on the 9th floor T2UW (9U) = 20 seconds The upper car when the upper car of Unit 2 is provisionally allocated to the upper car on the 9th floor The waiting time for passengers is T2LW (9U) = 0 seconds.

Next, the evaluation values E1U and E of the upper and lower cages of each unit
Performs 1L, E2U, E2L calculations. In the present embodiment, with respect to the evaluation regarding the waiting time, the sum of the predicted non-response time when the cars of each car are provisionally allocated is set as the allocation evaluation value,
The calculation method is not limited to this.
Predicted unresponsive time of 2 as stated in No. 8464
Various calculation methods can be applied, such as evaluating the sum of powers and maximizing the predicted non-response time.

The evaluation values of the upper and lower cars of each unit are as follows: Evaluation value of the upper car of Unit 1 E1U = T1UU (9U) + T1UW (9U) = 30 + 10 = 40 seconds Evaluation value E1L = T1LL (9U) of the lower car of Unit 1 + T1LW (9U) = 32 + 0 = 32 seconds Evaluation value of the upper car of Unit 2 E2U = T2UU (9U) + T2UW (9U) = 24 + 20 = 44 seconds Evaluation value of E2L = T2LL (9U) + T2LW (9U) = 26 + 0 = 26 seconds, and finally, the lower car of the second car is selected as the car with the smallest evaluation value and the car controller 2 outputs the hall call response allocation command.

According to the method of this embodiment, the lower car of the second car is selected, but if the waiting time of passengers in the car is not taken into consideration, the car with the smallest evaluation value becomes the upper car of the second car, and the response is given. The basket will be different.

Therefore, it can be said that the present embodiment takes into account not only the service of waiting passengers in the hall but also the service of passengers in the car. As described above, according to the present embodiment, in the semi-double operation, the waiting time of passengers in the car and the waiting time of passengers in the hall are used as the evaluation indexes of the allocation. Can be equalized.

FIG. 4 is a flow chart showing the operation of the control device for the double deck elevator showing the second embodiment of the present invention. The overall configuration diagram is the same as that of FIG. 1, and therefore its description is omitted here. Incidentally, also in the second embodiment
It is assumed that two double deck elevators are installed in a 12-story building.

Next, the operation of the second embodiment will be described with reference to the operation flowchart of FIG. 4, taking the case of FIG. 3 as an example.
According to the example shown in FIG. 3, when the 9th floor upper hall call is generated, the allocation control means 5-2 performs the evaluation based on the predicted non-response time and the waiting time on a car basis. The predicted arrival time when the ninth floor upper hall call is provisionally assigned to the upper and lower cars is the same as that in FIG. 2, so detailed description thereof will be omitted here and the result will be as follows. Predicted non-response time when the upper car of Unit 1 is provisionally assigned to the upper floor on the 9th floor T1UU (9U) = 30 seconds Predicted unresponsive time when the upper car of Unit 1 is provisionally assigned to the upper car on the 9th floor T1LL (9U ) = 32 seconds Predicted non-response time when the upper car of Unit 2 is provisionally assigned to the upper floor of the 9th floor T2UU (9U) = 24 seconds Unpredicted response when the upper car of Unit 2 is tentatively assigned to the upper car of the 9th floor Time T2LL (9U) = 26 seconds.

Next, assuming that the upper car on the ninth floor, which is the target floor, is assigned to the upper and lower cars of each unit, the waiting time for passengers in the upper and lower cars on the target floor (9th floor) is set. When calculated, the lower car passenger waiting time when the upper car of Unit 1 is provisionally allocated to the upper floor of the 9th floor T1UW (9U) = 0 seconds The upper car of Unit 1 is provisionally allocated to the upper car of the 9th floor Waiting time for car passengers T1LW (9U) = 0 seconds Waiting time for lower car passengers when the 9th floor upward direction is provisionally assigned to the upper car of Unit 2 T2UW (9U) = 10 x 1 = 10 seconds The waiting time for passengers in the upper car when the upper car on the 9th floor is temporarily assigned to the lower car is T2LW (9U) = 0 seconds.

The evaluation values of the upper and lower cars of each unit are as follows: Evaluation value of the upper car of Unit 1 E1U = T1UU (9U) + T1UW (9U) = 30 + 0 = 30 seconds Evaluation value E1L = T1LL (9U) of the lower car of Unit 1 + T1LW (9U) = 32 + 0 = 32 seconds Evaluation value of the upper car of Unit 2 E2U = T2UU (9U) + T2UW (9U) = 24 + 10 = 34 seconds Evaluation value of E2L = T2LL (9U) + T2LW (9U) = 26 + 0 = 26 seconds, and finally, the lower car of the second car is selected as the car with the smallest evaluation value and the car controller 2 outputs the hall call response allocation command.

According to the method of this embodiment, the lower car of the second car is selected, but the floor (9th floor) to which the hall call is assigned
If the waiting time of passengers in the car is not taken into consideration, the car with the smallest evaluation value will be the upper car of the second car, and the response car will be different.

Therefore, it can be said that according to the present embodiment, not only the service of waiting passengers in the hall but also the service of passengers in the car are added. As described above, according to the present embodiment, in the semi-double operation, the waiting time of the waiting passengers at the hall call generation floor and the waiting time of the passengers in the car are used as the allocation evaluation index. The services of passengers waiting in the hall and the services of passengers in the car can be averaged.

FIG. 5 is a flow chart showing the operation of the control device for the double deck elevator showing the third embodiment of the present invention. The overall configuration diagram is the same as that of FIG. 1, and therefore its description is omitted here. Incidentally, also in the third embodiment
It is assumed that two double deck elevators are installed in a 12-story building.

Next, the operation of the third embodiment will be described with reference to the operation flowchart of FIG. 5, taking the case of FIG. 3 as an example.
According to the example shown in FIG. 3, when the 9th floor upper hall call is generated, the allocation control means 5-2 performs the evaluation based on the predicted non-response time and the waiting time on a car basis. The predicted arrival time when the ninth floor upper hall call is provisionally assigned to the upper and lower cars is the same as that in FIG. 2, so detailed description thereof will be omitted here and the result will be as follows. Predicted non-response time when the upper car of Unit 1 is provisionally assigned to the upper floor on the 9th floor T1UU (9U) = 30 seconds Predicted unresponsive time when the upper car of Unit 1 is provisionally assigned to the upper car on the 9th floor T1LL (9U ) = 32 seconds Predicted non-response time when the upper car of Unit 2 is provisionally assigned to the upper floor of the 9th floor T2UU (9U) = 24 seconds Unpredicted response when the upper car of Unit 2 is tentatively assigned to the upper car of the 9th floor Time T2LL (9U) = 26 seconds.

Next, when it is assumed that the upper car on the 9th floor, which is the target floor, is assigned to the upper and lower cars of each unit, the passengers in the upper and lower cars wait until the car responds to the hall call and departs from the current position. With respect to the time, a total sum is calculated by multiplying a weighting that increases by a predetermined value for each stop. In the present embodiment, assuming that the number of stops is multiplied as a weighting value, the waiting time of the lower car passenger when the upper car of the first car is provisionally allocated to the upper floor of the ninth floor based on the result of FIG. 2 T1UW (9U) = 10 x 1 sec. Upper car passenger waiting time when the lower car of Unit 1 is tentatively assigned to the upper car on the 9th floor T1LW (9U) = 0 seconds When the upper car of Unit 2 is tentatively assigned to the upper car on the 9th floor Waiting time for passengers in the lower car T2UW (9U) = 10 x 1 + 10 x 2 = 30 seconds Waiting time for passengers in the upper car when the upper car on the 9th floor is provisionally allocated to the lower car of Unit 2 T2LW (9U) = 0 Seconds.

The evaluation values of the upper and lower cars of each unit are as follows: Evaluation value of the upper car of Unit 1 E1U = T1UU (9U) + T1UW (9U) = 30 + 10 = 40 seconds Evaluation value of the lower car E1L = T1LL (9U) + T1LW (9U) = 32 + 0 = 32 seconds Evaluation value of the upper car of Unit 2 E2U = T2UU (9U) + T2UW (9U) = 24 + 30 = 54 seconds Evaluation value of E2L = T2LL (9U) + T2LW (9U) = 26 + 0 = 26 seconds, and finally, the lower car of the second car is selected as the car with the smallest evaluation value and the car controller 2 outputs the hall call response allocation command.

According to the method of this embodiment, the lower car of the second car is selected. However, if the waiting time of passengers in the car is not taken into consideration, the car with the smallest evaluation value becomes the upper car of the second car, and the response is given. The basket will be different.

Therefore, it can be said that according to the present embodiment, not only the service of waiting passengers in the hall but also the service of passengers in the car should be added. As described above, according to the present embodiment, in the semi-double exercise, each time the above-mentioned event occurs so that the passengers in the car do not have a call stop in the same car several times before reaching the destination floor. Since the weight to be multiplied by the waiting time is increased, it is possible to reduce the discomfort of passengers in the car and average the services of passengers waiting in the hall and the services of passengers in the car.

FIG. 6 is an overall configuration diagram of a control device for a double-deck elevator showing a fourth embodiment of the present invention. The same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. Only the points will be described.

2, the hall number detection means 5-3, and the hall call registration means 5-1 and the allocation control means 5-2 are the same as those in FIG. 1, and therefore their explanations are omitted here.

The hall number detecting means 5-3 is means for detecting the number of waiting passengers at the hall when the hall call is registered, and from the images by the ITVs 9-1 to 9-12 installed in the hall, The number of people is detected by image recognition processing.

Further, in FIG. 6, the car control device 1 responds to the hall call received from the group management control device 5 and issues a response to the group management control device 5 by issuing a known hall call. The response means 1-1, the well-known driving control means 1-2 for controlling the running and stopping of the upper and lower cars, and the well-known driving direction control means 1-for determining the traveling directions of the upper and lower cars.
3. Well-known door control means 1-4 for controlling the door closing of the upper cab and lower cab, respectively. Well-known car call registration means 1 for controlling the car calls of the upper and lower cabs 1-
5. I installed in the upper and lower cabs respectively
It is composed of a well-known car passenger number detecting means 1-6 for detecting the number of passengers in the car from the TVs 7U, 7L, and is the same as FIG. 1 except for the car passenger detecting means 1-6, and therefore its explanation is omitted here. .

The car passenger number detecting means 1-6 detects the number of passengers in the car by the image recognition processing similarly to the passenger number detecting means 5-3. As a method of detecting the number of passengers in the car, a method of counting passengers using a well-known photoelectric device or a well-known ultrasonic device installed on the elevator door, a passenger in the car using a well-known car load detector There is a method to detect the number of people. The car control device 2 of the second car is also constructed in the same manner as the first car.

Next, the operation of the fourth embodiment will be described with reference to the operation flowchart of FIG. 7, taking the case of FIG. 3 as an example.
FIG. 7 is a flowchart showing the operation of the allocation control means 5-2, the number of passengers detection means 5-3, and the car passenger number detection means 1-6 and 2-6 of the car control devices 1 and 2 of the group management control device 5. .

In accordance with the example shown in FIG. 3, when an upper floor hall call is generated, the number of passengers on the 9th floor is detected by the hall number detecting means 5-3 from the image from the ITV 9-9 installed on the 9th floor. IT installed in the upper and lower cages of each unit
Based on the images from V7U, 7L, 8U and 8L, the car passenger number detecting means 1-6 and 2-6 detect the number of passengers in the upper and lower cars of each car. Further, the allocation control means 5-2 performs an evaluation based on the predicted non-response time and the waiting time for each car. Fig. 2 shows the estimated arrival time when the number of people waiting on the 9th floor is one and the upper floor hall call is temporarily assigned to the upper and lower cars.
Therefore, detailed description is omitted here, and the result is as follows. Predicted non-response time when the upper car of Unit 1 is provisionally assigned to the upper floor on the 9th floor T1UU (9U) = 30 seconds Predicted unresponsive time when the upper car of Unit 1 is provisionally assigned to the upper car on the 9th floor T1LL (9U ) = 32 seconds Predicted non-response time when the upper car of Unit 2 is provisionally assigned to the upper floor of the 9th floor T2UU (9U) = 24 seconds Unpredicted response when the upper car of Unit 2 is tentatively assigned to the upper car of the 9th floor Time T2LL (9U) = 26 seconds.

Next, when it is assumed that the upper car on the 9th floor, which is the target floor, is assigned to the upper and lower cars of each unit, the passengers in the lower car wait for the car to respond to the hall call and depart from the current position. With respect to the time spent, a total sum is calculated by multiplying the expected number of passengers in the car at each stop by the time spent waiting. The predicted number of passengers in each car at each stop can be roughly calculated by the number of passengers obtained by dividing the quotient obtained by dividing the current number of passengers in the car by the number of car calls from the initial number of passengers each time the vehicle is stopped.

In this embodiment, the first car is traveling on the 4th and 3rd floors, and one passenger is in the lower car, and the second car is one passenger in the upper car when departing from the first and second floors, and the number of the lower car is two passengers. Then, based on the results of Fig. 2, the waiting time for passengers in the lower car when the upper car of Unit 1 is provisionally allocated to the upper car on the 9th floor T1UW (9U) = 10 x 1 seconds 9 floors above the lower car of Unit 1 Waiting time for passengers in the upper car when directions are provisionally allocated T1LW (9U) = 0 seconds Waiting time for passengers in the lower car when the upper car of Unit 2 is provisionally allocated to the upper floor on the 9th floor T2UW (9U) = 10 × 2 + 10 × 2 = 40 seconds The upper car passenger's waiting time T2LW (9U) = 0 seconds when the upper car on the 9th floor is provisionally allocated to the lower car of Unit 2.

The evaluation values of the upper and lower cars of each unit are as follows: Evaluation value of the upper car of Unit 1 E1U = T1UU (9U) + T1UW (9U) = 30 + 10 = 40 seconds Evaluation value E1L = T1LL (9U) of the lower car of Unit 1 + T1LW (9U) = 32 + 0 = 32 seconds Evaluation value of the upper car of Unit 2 E2U = T2UU (9U) + T2UW (9U) = 24 + 40 = 64 seconds Evaluation value of E2L = T2LL (9U) + T2LW (9U) = 26 + 0 = 26 seconds, and finally, the lower car of the second car is selected as the car with the smallest evaluation value and the car controller 2 outputs the hall call response allocation command.

According to the method of this embodiment, the lower car of the second car is selected, but if the waiting time of passengers in the car is not taken into consideration, the car with the smallest evaluation value becomes the upper car of the second car, and the response is given. The basket will be different.

Therefore, it can be said that according to the present embodiment, not only the service of waiting passengers in the hall but also the service of passengers in the car should be added. As described above, according to the present embodiment, in the semi-double exercise, the waiting time and the waiting time, which are the evaluation indexes of the evaluation calculation, are multiplied by the number of passengers in the target car or the number of waiting passengers in the hall to be assigned and evaluated. Since it is a value,
It is possible to average the services of each person including passengers waiting in the hall and passengers in the car.

FIG. 8 is an overall configuration diagram of a control device for a double-deck elevator showing a fifth embodiment of the present invention. The same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. Only the points will be described.

In the fifth embodiment, it is assumed that two double deck elevators are installed in a 12-story building. In FIG. 8, the group management control device 5 has a hall destination call 10 provided at the hall on each floor.
Well-known hall destination call registration means 5-11 for controlling registration of -1 to 10-12, and allocation evaluation calculation for the hall and hall destination calls 10-1 to 10-12 according to the state of No. 1 and No. 2 It is configured by the allocation control means 5-2. The well-known hall destination call registration means 5-11 is the hall call registration means 5-1.
Unlike, the destination of the waiting passengers can be registered in advance, and the call is transferred to the car call registration means of the car call control device that responded when the car got on the car, so there is no need to register the car call In the means 5-2, since it is possible to evaluate the allocation including the destination information,
There is an advantage that the forecast of the landing can be prevented and the first arrival due to the car call can be prevented.

Next, the operation of the fifth embodiment will be described with reference to the operation flowchart of FIG. 9, taking the case of FIG. 3 as an example.
FIG. 9 is a flowchart showing the operation of the allocation control means 5-2 of the group management control device 5.

According to the example shown in FIG. 3, when the destination call button on the 10th floor is pressed on the 9th floor, the allocation control means 5-2 performs the evaluation based on the predicted non-response time and the waiting time for each car. The estimated arrival time when the destination call on the 9th floor is provisionally assigned to the upper and lower cars is the same as that in FIG. 2, so a detailed description is omitted here and the result is as follows. Predicted non-response time when the upper car of Unit 1 is provisionally assigned to the upper floor on the 9th floor T1UU (9U) = 30 seconds Predicted unresponsive time when the upper car of Unit 1 is provisionally assigned to the upper car on the 9th floor T1LL (9U ) = 32 seconds Predicted non-response time when the upper car of Unit 2 is provisionally assigned to the upper floor of the 9th floor T2UU (9U) = 24 seconds Unpredicted response when the upper car of Unit 2 is tentatively assigned to the upper car of the 9th floor Time T2LL (9U) = 26 seconds.

Next, from the current position where it is assumed that the destination car on the ninth floor, which is the target floor, is assigned to the upper and lower cars of each unit, until the vehicle responds to the tenth floor, which is the destination floor of the waiting passenger on the ninth floor, and starts. When the waiting time for passengers in the upper and lower cars is calculated, the waiting time for passengers in the lower car when tentatively allocating the upper car of the 9th floor to the upper car of Unit 1 based on the result of Fig. 2 T1UW (9U) = 10 × 1 second Upper car passenger waiting time when the lower car of Unit 1 is temporarily allocated to the upper floor of the 9th floor T1LW (9U) = 0 seconds When the upper car of Unit 2 is temporarily allocated to the upper floor of the 9th floor Waiting time for passengers in the lower car T2UW (9U) = 10 × 2 + 10 × 1 = 30 seconds Waiting time for passengers in the upper car when the 9th floor upward direction is temporarily assigned to the lower car of Unit 2 T2LW (9U) = 0 seconds Becomes

The evaluation values of the upper and lower cars of each unit are as follows: Evaluation value of the upper car of Unit 1 E1U = T1UU (9U) + T1UW (9U) = 30 + 10 = 40 seconds Evaluation value of the lower car E1L = T1LL (9U) + T1LW (9U) = 32 + 0 = 32 seconds Evaluation value of the upper car of Unit 2 E2U = T2UU (9U) + T2UW (9U) = 24 + 30 = 54 seconds Evaluation value of E2L = T2LL (9U) + T2LW (9U) = 26 + 0 = 26 seconds, and finally, the lower car of the second car is selected as the car with the smallest evaluation value and the car controller 2 outputs the hall call response allocation command.

According to the method of this embodiment, the lower car of the second car is selected, but if the waiting time of passengers in the car is not considered, the car with the smallest evaluation value becomes the upper car of the second car, and the response The basket will be different.

Therefore, according to the present embodiment, it can be said that not only the service of waiting passengers to the floor where the call is generated and the service of passengers in the car but also the service of passengers in the car to the destination floor of the waiting passengers are added.

As described above, according to this embodiment, in the semi-double operation, the time spent waiting for the destination floor of the passenger waiting for the landing is assigned and evaluated, so that the service of the passenger in the car can be improved.

FIG. 10 is an overall block diagram of a control device for a double-deck elevator showing a sixth embodiment of the present invention. The same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. Only the points will be described.

In the sixth embodiment as well, description will be made assuming that two double deck elevators are installed in a 12-story building. In FIG. 10, the group management control device 5 includes a hall call registration means 5-1 and an allocation control means 5-.
2, passenger number detection means 5-3 and traffic demand determination means 5-
4, the hall call registration means 5-1, the allocation control means 5-2, and the hall number detection means 5-3 are the same as those in FIG. 6, and therefore their explanations are omitted here.

The traffic demand determination means 5-4 starts a timer when a hall call occurs, measures the elapsed time (waiting time) until the car responds to the hall call, and calls the hall call 1
It is a means of calculating the average waiting time per trip and judging the state of traffic demand from that value. Here, the average waiting time is used as the index of traffic demand, but the number of landing calls per unit time, the maximum number of passengers in the car, and the like can be considered.

Next, the operation of the sixth embodiment will be described with reference to the operation flowchart of FIG. 11, taking the case of FIG. 12 as an example.
FIG. 11 shows the allocation control means 5-2, the number of passengers detection means 5-3, the traffic demand determination means 5-4, and the car passenger number detection means 1-6, 2 of the car control devices 1 and 2 of the group management control device 5. 6 is a flowchart showing the operation of No. 6.

When a 10th floor upward hall call is generated as in the case shown in FIG. 12, the current demand is judged to be quiet when the average waiting time is less than a predetermined value by the traffic demand judging means 5-4. In the allocation control means 5-2, the evaluation based on the waiting time is performed for each car. When it is determined that it is not out of balance, an allocation evaluation calculation is performed using the estimated arrival time and the waiting time as evaluation indices. There are two passengers in the upper car and two passengers in the lower car while the first car is traveling on the 4th and 3rd floors. The passengers in the lower car are the same as those in the 1st car when the 2nd car leaves the 2nd and 1st floors. Then, the car on Unit 1 responded to the temporary call assigned to the upper floor of the 10th floor, and there was no call to the lower car before departure, and there were passengers only on the 6th and 5th floors. Since it is a person, the evaluation value E1U (10
U) is 20 seconds, and the state where there is a passenger without calling the upper car by the time the departure car of Unit 1 responds to the temporary call for the 10th floor that is temporarily assigned, and stops on the 8th and 7th floors and calls for the 10th floor Since it is on the second floor when responding, and there is only one passenger in the upper car at that time, the evaluation value E1L (10U) of the lower car of Unit 1 is 20 seconds.
Similarly, the evaluation value E2U (10U) of the upper car of Unit 2 is 20 seconds and the evaluation value E2L (10U) of the lower car is 10 seconds. Finally, the lower car of Unit 2 is selected as the smallest evaluation value car, and the car A hall call response assignment command is output to the control device 2.

According to the method of this embodiment, the lower car of the second car is selected, but if the waiting time of passengers in the car is not taken into consideration, the car with the smallest evaluation value becomes the upper car of the second car, and the response is given. The basket will be different.

Therefore, according to the present embodiment, it can be said that the service of passengers in the car is prioritized during a quiet time. As described above, according to the present embodiment, the waiting time during a quiet time is used as the evaluation index, so that the discomfort of passengers in the car is reduced and the service of passengers waiting at the hall and the service of passengers in the car are averaged. be able to.

[0074]

As described above, according to the control device for a double-deck elevator according to the present invention, the allocation evaluation index is controlled on the basis of the predicted arrival time and the waiting time, so that the passengers waiting in the hall and the passengers in the car can be controlled. Services can be equalized.

Further, in a quiet time when the estimated arrival time becomes short, the allocation control is performed based on the waiting time, so that not only the service of passengers in the car is improved but also the deterioration of the operation efficiency can be prevented.
