Abstract

PURPOSE:To reduce the number of times of stopping and improve the efficiency of running by calculating the number of times of stopping upper and lower cages respectively until they reach the final call story to be responded to select the cage having the least number of times of stops as the cage responsive to the story registered at destination call. CONSTITUTION:An upper cage 3AH is adapted to respond to the stop call of even number stories and a lower cage 3AL is adapted to respond to the stop call of odd number stories. A destination story desired by a waiting caller in the stop is registered as a destination call by a stop destination call registering means 14. The destination call is temporarily alloted to the upper and lower cages 3AH, 3AL. Then, the number times of stops until the cages reach the final call story to be responded are respectively calculated with respective to the upper and lower cages 3AH, 3AL. According to the calculated result, the cage having the least number of stops is selected by an upper and lower cage response selecting means 16 as a cage responsive to a story at which the destination call is registered. Thus, the number of times of stopping can be reduced and waiting times for cage call and stop call be shortened.

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.

[0002]

2. Description of the Related Art Generally, in a double-deck elevator, an upper cab (hereinafter referred to as an upper car) for hall calls on even floors and a lower cab (hereinafter, referred to as an upper basket) for hall calls on an odd floor. , Which is called a lower basket) is being operated (hereinafter referred to as a double operation). This double operation can be used like a general elevator for passengers going from even floor to even floor and passengers going from odd floor to odd floor, but passengers going from even floor to odd floor and from odd floor to even floor are It is necessary to go up and down only the first floor using the stairs, which is inconvenient for the users. Therefore, such double operation is applied during peak hours such as at work and during lunch, and in other time zones, a semi-double operation is performed. This semi-double operation means that passengers going to the even floors and passengers going to the odd floors are respectively placed in the upper and lower cars only on the departure standard floor, and after leaving the departure standard floor,
It is an operation in which both the upper and lower cars can be stopped at any floor. In this semi-double operation, passengers can move directly to any floor, which is convenient, but since it corresponds to any destination floor of passengers in the upper and lower cars, the operation efficiency is lower than in double operation.

Both the double operation and the semi-double operation have advantages and disadvantages in use, and therefore, the double operation and the semi-double operation are actually switched for each time period. In such a situation, if the car call and the landing call can be serviced with one stop, mainly for the purpose of improving operating efficiency in semi-double operation, the upper car should respond to the even floors and the lower car to the odd floors. Without stopping, service is performed with one stop, or when there are continuous landing calls, the service is performed with one stop as described above to prevent a decrease in operating efficiency.

[0004]

However, in the conventional double operation or semi-double operation, as shown in FIG. 3 (a), the passengers in the lower car boarding from the departure reference floor M1 floor during the semi-double operation move to the 7th floor. Consider a case where a car call is registered and a waiting passenger who goes to the departure standard floor M2 on the 10th floor has registered a lower hall call on the 10th floor. Now, for example, when a waiting passenger on the 5th floor registers and waits for a destination call to the 8th floor, the destination floor of the hall is unknown until the call is answered. A lower car will respond, and the destination floor for the upper hall call on the 5th floor is the 8th floor, as shown in FIG.
As shown in (b), if the upper hall call on the 5th floor is made to respond to the upper car, passengers heading from the departure standard floor M1 floor to the 7th floor for boarding and passengers heading from the 5th floor to the 8th floor for boarding once Despite being able to provide service by stopping the service, the service responded as shown in Fig. 3 (a), and the number of responses up to the 10th floor down hall call increased by one compared to Fig. 3 (b), resulting in reduced operating efficiency. Imitate.

The present invention has been made to solve the above-mentioned problems. A hall destination button is installed in the hall, information of the destination floor is input before the elevator responds, and the destination floor is set to respond first. It is an object of the present invention to provide an operation control device for a double-deck elevator that can reduce the number of times of stop by giving priority to the cars that can respond at the same stop and improve the operation efficiency.

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 makes an upper car respond to a hall call of an even floor and responds to a hall call of an odd floor. In the operation control device of the double-deck elevator that responds to the lower car, the hall destination call registration means for registering the destination floor desired by the waiting passenger at the hall as the destination call, and the destination call is temporarily assigned to the upper and lower cars. , Upper and lower car response selection means that calculates the number of stops until the final call floor to be answered for each of the upper and lower cars and selects the car with the least number of stops as the response car to the floor for which the destination call was registered And are provided.

The invention according to claim 2 is a hall where a destination floor desired by a waiting passenger is registered as a destination call at a hall where a plurality of double-deck elevators having upper and lower cars connected vertically are in service. The destination floor button and the newly generated destination call are temporarily assigned to the upper and lower cars of each double-deck elevator, and the expected arrival time to each floor where the assigned destination call is occurring is calculated. However, with the estimated arrival time, the evaluation value is calculated for each of the upper and lower cars of each double-deck elevator, and the car having the optimum evaluation value is provided with allocation control means for responding to the floor where the destination call is occurring. is there.

Furthermore, the invention according to claim 3 is a hall destination in which a destination floor desired by a waiting passenger is registered as a destination call in a hall where a plurality of double-deck elevators in which an upper car and a lower car are vertically connected are activated. When a new destination call is registered on the floor where the destination call has already been assigned to the call registration means and one of the upper and lower cars, the new registered destination call is taken into consideration in the up / down direction. The estimated arrival time to the floor where the destination call already assigned to each car is calculated is calculated, and the evaluation value for each of the upper and lower cars is calculated based on this estimated arrival time, and the destination call is newly added to the car having the optimum evaluation value. Allocation control means for responding to a newly generated floor is provided.

[0009]

In the control device for a double-deck elevator according to the first aspect of the present invention having the above-mentioned configuration, the destination call to the destination floor desired by the passenger at the landing is provisionally assigned to the upper car and the lower car, and the response schedule is set. The number of stops up to the final call floor is calculated for each of the upper and lower cars, and the car with the smallest number of stops is selected as the response car to the floor for which the destination call is registered.

Further, in the operation control device for a double-deck elevator according to the second aspect of the present invention, a passenger waiting at a hall where a plurality of double-deck elevators having upper and lower cars connected vertically are desired. A destination call to the destination floor is provisionally assigned to the upper and lower cars of each double-deck elevator, and the estimated arrival time to each floor where the assigned destination call is generated is calculated, and these estimated arrival times are calculated. Then, the evaluation value is obtained for each of the upper and lower cars of each double-deck elevator, and the car having the optimum evaluation value is made to respond to the floor where the destination call is occurring.

Further, in the control device for a double-deck elevator according to the second aspect of the present invention, a new destination call is registered in the floor where the destination call has already been assigned to one of the upper and lower cars. At this time, considering the newly registered destination call, the estimated arrival time to the floor where the destination call already assigned to the upper and lower cars is calculated, and the evaluation value of the upper and lower cars is calculated based on this estimated arrival time. Then, the car having the optimum evaluation value is made to respond to the floor newly generated by the destination call.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is an overall configuration diagram showing an embodiment according to the invention described in claim 1. Reference numeral 1 is a control device for controlling the double-deck elevator, and operation control means 11 for controlling the running and stopping of the upper and lower cars, and a traveling direction control means 1 for determining the traveling direction of the upper and lower cars depending on the landing place and the call registration state of the car.
2. Door control means 13 for controlling the opening and closing of the doors of the upper car and the lower car, and hall destination buttons 2-1 to 2-12 installed on each floor.
(In this embodiment, the 12th floor is taken as an example.) The hall destination call registration means 14 for registering, the car call registration means 15 for registering each car call of the upper car and the lower car, and the hall destination call. According to the registered destination floor information, it is composed of upper and lower car response selecting means 16 which preferentially responds to a car that can be stopped in the same way as a call to be answered earlier than the response floor. 3AH and 3AL are an upper car and a lower car, respectively.

Next, the operation of the double-deck elevator having the above structure will be described with reference to FIGS. 2 and 3.
FIG. 2 is a flow chart showing the operation of the upper and lower car response selecting means 16 of the control device 1, and the operation of issuing a response car command to the hall call to be stopped to the operation control means 11 and the traveling direction control means 12. It is shown. Figure 3
The call response will be described as an example.

The upper and lower cars are departure standard floors M2 and M1 respectively.
Since the destination call on the 8th floor was registered at the landing on the 5th floor after leaving the floor, the next stop floor of the upper and lower cars was detected at the timing before the answer calls were confirmed by the upper and lower cars 3AH and 3AL to start deceleration. And the 5th floor upward hall call is detected as the target (steps S31 and S32). If the upper and lower cars are not simultaneous responses but are responses by hall calls, step S35 and subsequent steps are performed (steps S33 and S3).
4). Assuming that you want the upper car to respond to the 5th floor hall call,
The number of stops up to the final call floor to be answered at the present time is calculated assuming that the response to the upward direction on the fifth floor and the destination call to the eighth floor on the fifth floor from the hall destination buttons 2-5 are made to respond (step 3).
5, 36). In the case of FIG. 3, it becomes the case of (b), and the upper and lower cars are stopped in the order of the 5th and 4th floor stop → the 8th and 7th floor stop → the 10th and 9th floor stop → the M2 and M1 floor stop. Times.

Next, suppose that the fifth floor upward hall call is tentatively answered by the lower car, and that the fifth floor upward call and the destination call on the fifth floor, the eighth floor, are answered, and the final call is scheduled to be answered in the same manner as the upper car. Calculate the number of stops up to the floor (step S3
7, S38). In the case of FIG. 3, it becomes the case of (a),
The upper and lower cars are stopped in the order of 6,5th floor stop → 8, 7th floor stop → 9, 8th floor stop → 10, 9th floor stop → M2, M1 floor stop, so the number of stops is five times.

Next, the stop counts calculated in steps 35, S36 and steps S37, S38 are compared. If the number of stops is the same, the even cars, which are normal responses, are selected as the upper car and the lower cars are selected as the response car (step S41). If they are not the same, a car with a small number of stops is selected as a response car (step S40). Figure 3
In the above example, the upper car is selected as the answering car, and the operation control means 11 is instructed to the answering car for the hall call on the fifth floor.

Next, an embodiment of the invention described in claim 2 will be described. FIG. 4 is an overall configuration diagram showing an embodiment,
It is assumed that two double-deck elevators are installed in a 12-story building.

1A and 1B are control devices for the first and second machines, respectively. The control devices 1A and 1B have the same configuration, and the control device 1A will be described. Responding to the hall call received from the group management control device 4,
The hall call response means 11A for instructing the group management control device 4 that it has responded, the operation control means 12A for controlling the running and stopping of the upper and lower cars, and the destination floor information registered by the hall destination call. Upper and lower car response selecting means 1 for giving priority to a car that can be stopped at the same time as a scheduled call
3A, driving direction control means 14A for determining the operating direction of the upper and lower cars, door control means 15A for controlling the opening and closing of the doors of the upper car and the lower car, and a car call registration means for controlling the car calls of the upper car and the lower car, respectively. 16A.
Note that the car control device 1B of the second car is also configured similarly to the first car. The group management control device 4 controls the registration of the hall destination buttons 2-1 to 2-12 provided on each floor, the hall destination call registration means 41, and the state of the first and second units with respect to the floor where the hall destination call occurs. Is configured by the allocation control means 42 for allocating the optimum car of the optimum car. Three
AH, 3AL and 3BH, 3BL are Unit 1 and 2 respectively
The upper and lower cars of the Unit.

Next, the operation of the operation control device for the double-deck elevator having the above structure will be described with reference to FIGS. 5 and 6. FIG. 5 is a flow chart showing the operation of the allocation control means 42 of the group management control device 4, and FIG. 6 is a view showing the operating state of each unit for explaining the operation.

The operation of the allocation control means 42 will be described with reference to FIG. According to the example of Fig. 6, the car call from the departure standard floor M1 floor to passengers on the 7th floor is registered in the lower car of the departure standard floor, and the destination floor call to the M2 floor on the 10th floor is assigned to the upper car. It is assumed that the duration of the landing call has passed, for example, 10 seconds. In car B, the car calls to the 12th floor by passengers from the departure standard floor M2 are registered in the upper car, and the landing destination floor call to the departure standard floor M2 on the 6th floor is assigned to the upper car. It is assumed that the duration of the landing call is 12 seconds.

In such a situation, consider the case where the eighth floor is registered as a hall destination call at the hall on the fifth floor and the answering machine to the upward hall call on the fifth floor is selected. Since the hall destination call on the 5th floor is registered and the first hall call is registered as the upward hall call, the allocation car for the hall call has not been determined, so the allocation control processing is started. The expected arrival times of the upper car and the lower car in the current state to arbitrary floors are calculated (step S53). The estimated arrival time is the time required to travel (travel time) from the distance between the current car position and the target floor,
It is calculated by adding the time required to stop from the number of stops on the intermediate floor, and if there is a landing destination floor call, it is possible to call the car to the floor where the destination call is registered when responding to that landing In the case of a normal vertical hall call that is not a hall destination call, it is common to calculate the inversion floor on the assumption that a car call will occur at a predetermined position as a derived car call.

In the case of FIG. 6, 1 of the car on the A-th car
Assuming that the estimated arrival time to the 0th floor down hall call is 2 seconds per floor as the traveling time and the stop time is 10 seconds,
After stopping the 8th and 7th floors, to respond to the 9th and 10th floors (6 × 2)
+10+ (2 × 2) = 26 seconds, and considering the call duration, the predicted arrival time T _1AH (10D) is 26 + 10.
= 36 seconds.

Next, it is assumed that a newly generated hall call, which is a hall call, and an 8th floor call, which is a registered destination floor call, are tentatively assigned to the upper car of the A car. The predicted arrival time to the floor is calculated (steps S54 and S55).

The expected arrival time of the car on the A-th car to the upward hall call on the 5th floor, which is the floor to be allocated, is 3 × 2 = 6 seconds,
The predicted arrival time T _2AHH (5U) is 6 + 0 = 6 seconds. Similarly, the predicted arrival time T _2AHH (10D) of the car on top of Unit A for a 10th floor down hall call is 5th and 4th floors for the upper and lower cars respectively →
36+ because it will stop on the 8th, 7th floor → 10, 9th floor
10 = 46 seconds.

Next, assuming that a newly generated hall call, which is a hall call, and an 8th floor call, which is a registered destination floor call, are temporarily assigned to the lower car of Unit A, the same as above.
Estimated arrival time T of the upper car of Unit A to the downstairs landing call
_{In 2AHL} (10D), the upper and lower cars are on the _{6th and 5th} floor → 8, respectively.
7th floor-> 9, 8th floor-> 10, 9th floor, so 46 + 1
0 = 56 seconds, and the predicted arrival time T _2ALL (5U) of the car below the car of No. A to the upward hall call on the fifth floor is 8 seconds (steps S56 and S57).

Similarly, with respect to the No. B machine, step S53 is similarly performed.
~ S57 is executed, and the predicted arrival time _T1BH (6D) of the car on the B car in the downward direction on the sixth floor in the current state is 42 + 12 =
It becomes 54 seconds, and the predicted arrival time T _2BHH (5U) of the car on the B floor to the car on the 5th floor up to the car landing on the 5th floor when the car on the 5th floor up and down is tentatively answered is 6 seconds and the 6th floor down _Estimated arrival time of the car on the Unit B to the landing T _2BHH (6
D) is 62 + 12 = 74 seconds.

Similarly, the predicted arrival time T _2BLL (5U) of the lower car of Unit B to the upper hall of the fifth floor when the call for the upper hall of the fifth floor is made to respond to the lower car of Unit B is 8 seconds and 6 seconds.
_Estimated arrival time of the car on the B car to the downstairs hall T _2BHL
(6D) is 62 + 12 = 74 seconds.

Next, the evaluation values E _AH , E _{AL of} the upper and lower cars of each unit,
E _BH and E _BL are calculated (step S59). In this embodiment, the sum of the predicted arrival times when the cars of the respective cars are temporarily allocated is used as the allocation evaluation value, but the calculation method of the allocation evaluation value is not limited to this, and the square of the predicted arrival time is used. It is possible to apply various calculation methods such as using the total sum of the evaluation values as the evaluation value or using the maximum value of the predicted arrival time.

[0029] The evaluation value of each unit up and down basket A Unit on the car evaluation value _{E AH = T 2AHH (5U)} + T 2AHH (10D) + T 1BH (6
D) = 6 + 46 + 54 = 106 A Unit under the car evaluation value _{E AL = T 2ALL (5U)} + T 2AHL (10D) + T 1BH (6
D) = 8 + 56 + 54 = 118 Evaluated value of car on B machine E _BH = T _2BHH (5U) + T _1AH (10D) + T _2BHH (6
D) = 6 + 36 + 74 = 116 Evaluated value of the lower car of Unit B E _BL = T _2BLL (5U) + T _1AH (10D) + T _2BHL (6
D) = 8 + 36 + 74 = 118, and the car of the car with the minimum evaluation value E _AH , which is the car of the car of No. A, becomes the assigned car of the fifth floor upward hall call.

Here, consider a case where the 5th floor upward call is not a hall destination floor call but a normal upward call, and the destination floor is uncertain before the answering car arrives. Since the destination floor for the upward call on the 5th floor is uncertain, if the same calculation as above is performed assuming that the derived car can call the upper car on the 12th floor and the lower car on the 11th floor, Upper car evaluation value E _AH = 6 + 64 + 54 = 124 Unit A lower car evaluation value E _AL = 8 + 64 + 54 = 126 Unit B upper car evaluation value E _BH = 6 + 34 + 64 = 106 Unit B lower car evaluation value E _BL = 8 + 34 + 64 = 108 and the minimum evaluation value _{Becomes EBH} , and the car on the B side is selected as the assigned car for the 5th floor upward call.

In the system according to the present invention, since the destination call in the upward hall call on the 5th floor is the 8th floor, the evaluation value of the car on Unit A that can respond at the same stop as the response schedule after the 5th floor upward response is As a result, the allocation is prioritized on the same stop. On the other hand, if the optimal car number is selected by the same allocation algorithm without considering the destination call, it becomes the car on the B car. From this, the system according to the present invention gives priority to the car of the car that can respond with the same stop. I can say.

Next, an embodiment of the invention described in claim 3 will be described. FIG. 7 is an overall configuration diagram. As with the configuration of FIG. 4, two double-deck elevators are installed, and the same unit upper and lower car response selection means 43 is provided in the group management control device 4. There is. The operation of the embodiment will be described with reference to FIGS.

According to the example shown in FIG. 9, both the fourth floor upward hall call and the eighth floor upward hall call are already assigned to the upper car in the car No. A, and the fourth floor before the machine A responds to the fourth floor upward hall call. This is a case where the upper and lower cars of the same unit are reassigned when a destination call to the 7th floor is added. FIG. 8 is a flow chart showing the operation of the upper and lower car response selecting means 43 of the group management control device 4. For a call already assigned by the assignment control means 42, a landing destination call (in this embodiment, 4
It is a destination call to the 7th floor in the floor. ) Is registered, the response selecting means 43 for the upper and lower cars of the same machine is activated. The current assigned car room assignment is canceled and the expected arrival time of the assigned car upper and lower cars is calculated.

In the case of FIG. 9, the allocation to the upper car of the fourth floor upward call is canceled, and the calculation is executed again (step S73). Next, the upper car is assigned to the upward call on the 4th floor, and the predicted arrival time at each hall call is calculated assuming that the destination car calls the 6th floor and 7th floor as the upper car to respond (steps S74, S75). . The predicted arrival time T _2AHH (4U) at the 4th floor upward hall is 4 + 10 = 14 seconds, and the predicted response time T _2AHH (8U) at the 8th floor upward hall is 42 + 5 = 47 seconds.

In the same manner, the predicted arrival time is calculated by assuming that the car on the fourth floor upward call responds to the car below the car A (steps S76 and S77). The estimated arrival time T _2ALL (4U) at the 4th floor upward landing is 6 + 10 = 16 seconds, which is 8
Predicted arrival time of the upper car to the upper floor landing T _2AHL (8U)
Is 32 + 5 = 37 seconds.

Next, an evaluation value is calculated as a summation allocation algorithm of the predicted arrival times of the already-assigned calls of the own machine (step S78), and the evaluation value E _AH = T _2AHH (4U) + T of the car on the A machine is calculated.
_2AHH (8U) = 14 + 47 = 61 Evaluation value of the lower car of Unit A E _AL = T _2ALL (4U) + T
_2AHL (8U) = 16 + 37 = 53 and the lower car, where the destination call is the same stop as the call to be answered on the 4th floor or later, is better than the upper car, which is the already assigned car, and is better in the same car. A response car change command from the car to the lower car is issued to the car control device 1A of Unit A,
The lower car, rather than the upper car, responds to the upward hall call on the fourth floor (steps S79 and S80).

In the present embodiment, the number of stops before the target floor is calculated as the response selecting means for the upper and lower cars, but the car that can call the destination floor call at the same stop as the call to be answered later It is not limited to the above as long as the purpose is to prioritize, but to detect the state itself that is the same stop and make the car that minimizes the number of times respond,
The car that minimizes the sum of the predicted waiting times up to each response floor may be returned. Further, the number of responses is not limited to one elevator, and the allocation of responses to upper and lower cars of assigned hall calls may be changed in a plurality of elevators.

In the present embodiment, the car allocating means for giving priority to a car that can answer at the same stop as the call at the hall and the destination floor and the call to be answered at the destination is also tentatively made to respond to the destination call and the hall call. Although the evaluation that reflects the assigned estimated arrival time has been described, the present invention is not limited to this. It is possible to add the number of times of the same stopping state as an evaluation value to the entire evaluation and the number of stopping times. May be added to the overall evaluation as an evaluation value. In addition, a car that is in the same stop state and responds within a predetermined time may be preferentially selected without passing through the evaluation formula. Further, in the present embodiment, two machine numbers have been described, but it is clear that the same can be applied to the case of three or more machines.

Even when the hall destination floor call is set not on all floors but on a specific floor, only the control of the set floor may be applied. Further, in the present embodiment, the configuration in which the hall destination calls in the same direction are assigned to the cars of the same car is described, but each car is prioritized over the cars of the cars that can respond with the same stop. Alternatively, the assigned number may be determined.

[0040]

As described above, according to the first aspect of the invention, the number of stoppages for one elevator is reduced by the upper and lower car response selecting means, so that the waiting time for the car call and the hall call is reduced. It can be shortened and the serviceability can be improved.

Furthermore, according to the inventions of claims 2 and 3, for a plurality of double-deck elevators, the destination call of the landing is provisionally assigned to the upper car and the lower car of each unit and evaluated, and the optimum By assigning to the basket,
The waiting time to each landing can be shortened and the operation efficiency of the entire system can be improved.

As described above, according to the present invention, the call registered as the car call in the car and the same stop scheduled for the subsequent response are not prioritized as in the prior art, but the landing before the call is answered. Based on the destination call information, respond to the upper and lower cars so as to reduce the number of car stops as much as possible, and in a multiple car system, consider the predicted arrival time for each upper and lower car and decide the assigned car and the assigned car As a result, the waiting time for each answering call, the boarding time can be shortened, the operating efficiency of the multiple-unit system can be improved, and the service performance can be improved.
