Embodiment 1 FIG.
1 and 2 relate to Embodiment 1 of the present invention. FIG. 1 is a block diagram showing the configuration of an elevator control device, and FIG. 2 is a flowchart showing the operation of the elevator control device.
A landing destination call registration device 1 shown in FIG. 1 is installed at an elevator landing (not shown). The landing is provided on each floor where an elevator car (not shown) stops. The elevator car can move up and down between a plurality of floors and stop at two or more floors. Accordingly, the hall destination call registration device 1 is installed at halls of two or more floors.

  The landing destination call registration device 1 is for registering a landing call specifying a destination floor desired by a user at the landing, that is, a landing destination floor call. For this reason, the landing destination call registration device 1 is provided with an operation unit (not shown) that can accept a call registration operation specifying a destination floor by the user.

  As an example of this operation unit, there is one having a destination floor button corresponding to each floor where the car can be stopped. As another example, there is one having a so-called numeric keypad including buttons corresponding to numbers from 0 to 9. In any of these examples, a button with a mechanical contact may be used, or a touch panel may be used.

  When the user operates the landing destination call registration device 1, an operation signal corresponding to the operation content is output from the landing destination call registration device 1 on which the operation is performed. The operation signal output from the landing destination call registration device 1 is input to the car control device 2. The car control device 2 controls the operation related to the operation of the elevator car. The car control device 2 includes a call registration unit 3, a getting-off time prediction unit 4, and a door opening time determination unit 5.

  The call registration unit 3 registers a landing destination call based on an operation to the landing destination call registration device 1. More specifically, the call registration unit 3 registers a landing destination call based on the operation signal output from the landing destination call registration device 1. The boarding floor of the landing destination call is the floor where the landing destination call registration device 1 to which the operation signal is output is installed. The destination floor of the landing destination call is a floor designated by the user as the destination floor in the operation when the operation signal is output.

  As the landing destination call registration device 1, a personal authentication device including a card reader and / or a fingerprint collation device may be used. In this case, for example, the call registration unit 3 registers a call to a destination floor that is set in advance in association with the authenticated individual in accordance with the personal authentication result in the landing destination call registration device 1.

  The car control device 2 controls the operation of the car so as to respond to the landing destination call registered by the call registration unit 3 in this way. At this time, looking at one landing destination call, first, the car is run to the boarding floor of the landing destination call, and the user who registered the landing destination call is put on the car. Then, the car is driven to the destination floor of the landing destination call, and the user gets off at the destination floor.

  The getting-off time predicting unit 4 predicts the time required for the user to get off the car at the destination floor when the car stops at the destination floor of the landing destination call (hereinafter referred to as “getting-off time”). . The getting-off time prediction unit 4 includes a determination unit 4a.

  When there are a plurality of landing destination calls registered by the call registration unit 3, the determination unit 4 a determines a predetermined exit route for each destination floor based on the boarding floor and the destination floor of each of the plurality of landing destination calls. It is determined whether an unsecured condition is satisfied. The unsecured getting-off condition is a condition where a user who is going to get off at a certain destination floor can judge that the moving route in the car to get off from the car to the landing on the destination floor is not secured. is there.

  As a condition for not securing the departure route, for a plurality of registered destination destination calls, the destination floor of a certain destination destination call is another destination destination call at which the destination floor stops after the boarding floor of the one destination destination call. The first requirement that it exists between the boarding floor and the destination floor is set first.

  As a specific example of satisfying this first requirement, there is registered a hall destination call with a boarding floor of the third floor and a destination floor of the seventh floor, and a hall destination call with the boarding floor of the fifth floor and the destination floor of the ninth floor. This is the case. In such a case, after the user gets on the third floor, the user also gets on the fifth floor. Then, the user who got on the third floor is more likely to be in the back of the car than the user who got on the fifth floor. When the car stops on the 7th floor, the destination floor of the user who gets on the 5th floor is the 9th floor, so this user does not get off on the 7th floor. Therefore, it can be determined that there is a high possibility that the route for the user who gets on the third floor to get off on the seventh floor is blocked by the user who gets on the fifth floor.

  However, if there are few users on board and there is room in the car, a route for getting off may be secured even if the first requirement described above is satisfied. Therefore, in order to further improve the accuracy of determining whether or not a route for getting off the vehicle is secured, the following second requirement may be included in the unsecured route getting-off condition.

  The second requirement is that the number of passengers in the car when arriving at the destination floor of the one landing destination call is greater than or equal to a predetermined number. In this case, the determination unit 4a determines that the getting-off route unsecured condition is satisfied when both the first requirement and the second requirement are satisfied. When the first requirement is satisfied and the second requirement is further satisfied, more than a certain number of users are in the car. For this reason, it can be judged that the possibility that the space in the car has no room and the route for getting off is not secured is very high.

  The number of passengers in the car can be obtained based on the detection result of the scale device that detects the load in the car. Alternatively, the number of passengers can be obtained based on a captured image of a camera that captures the situation in the car.

  Alternatively, the number of passengers in the car can be obtained by considering the registered number of calls and the registered call boarding floor and destination floor. In this case, since no additional equipment such as a scale device or a camera is required, it can be implemented with an inexpensive and simple configuration.

  The getting-off time predicting unit 4 predicts the getting-off time at each destination floor using the determination result by the determining unit 4a. In the destination floor where it is determined by the determination unit 4a that the getting-off route unsecured condition has been established, the predicted getting-off time becomes longer than the specified value.

  The door opening time determining unit 5 determines the door opening time of the car when stopping at each destination floor based on the getting off time predicted by the getting off time predicting unit 4. More specifically, the door opening time determination unit 5 extends the door opening time from the standard door opening time when the predicted getting off time is longer than the specified value. Therefore, in this case, the door opening time will be extended if the getting-off route unsecured condition is satisfied. The car control device 2 controls the opening and closing of the car based on the door opening time determined by the door opening time determining unit 5.

The operation flow of the elevator control apparatus configured as described above will be described with reference to the flowchart of FIG.
First, in step S <b> 1, the car control device 2 confirms whether a new landing destination call is registered by the call registration unit 3. If a new landing destination call is registered, the process proceeds to step S2. If a new landing destination call is not registered, step S1 is repeated until it is registered.

  In step S2, the determination unit 4a uses the new landing destination call registered in step S1 and the information on the boarding floor and destination floor of the already registered landing destination call. Check if the requirements are met. That is, the determination unit 4a determines whether or not the destination floor of the one landing destination call that the user gets on first is between the boarding floor and the destination floor of the other landing destination call that responds later. To do.

  If it is determined in step S2 that the first requirement is not satisfied, the process ends. On the other hand, if it is determined that the first requirement is satisfied, the process proceeds to step S3.

  In step S <b> 3, the determination unit 4 a checks whether or not the second requirement of the getting-off route unsecured condition is satisfied. That is, the determination unit 4a determines whether or not the number of passengers in the car at the time when the car arrives at the destination floor of the one landing destination call on which the user gets on first is greater than or equal to the reference.

  If it is determined in step S3 that the second requirement is not satisfied, the process ends. On the other hand, if it is determined that the second requirement is satisfied, the process proceeds to step S4.

  In step S4, the getting-off time prediction unit 4 sets the estimated getting-off time at the destination floor of the one landing destination call that the user gets on earlier than a prescribed value. Then, the process proceeds to step S5.

  In step S5, the car control device 2 checks whether or not the car has arrived at the destination floor of the landing destination call. If the car has arrived at the destination floor, the process proceeds to step S6. If the car has not arrived at the destination floor, step S5 is repeated until it arrives.

  In step S <b> 6, the door opening time determination unit 5 determines the door opening time at the destination floor on the basis of the getting off time predicted by the getting off time prediction unit 4. Then, the car control device 2 opens the car according to the determined door opening time. When step S6 is completed, the series of processing is completed.

  The elevator control device configured as described above is installed at a landing on each floor where the elevator car stops, and is a landing destination call registration device 1 that can accept a call registration operation specifying a desired destination floor by a user. And when there are a plurality of landing destination calls registered by the call registration unit 3 based on an operation to the landing destination call registration device 1, and a plurality of landing destination calls, Based on the boarding floor and the destination floor, a determination unit 4a for determining whether or not a predetermined getting-off route unsecured condition is established for each destination floor, and using the determination result by the determination unit 4a, A getting-off time prediction unit 4 for predicting a getting-off time necessary for getting off at the destination floor, and a door-opening time decision for determining the door opening time of the car based on the getting-off time predicted by the getting-off time prediction unit 4 And Part 5, and a.

  For this reason, the prediction accuracy of the time required for the user to get off at the stop floor can be improved. And when the route which the user in the back of a car gets off is not ensured, suppressing the extension of unnecessary door opening time, an appropriate door opening time can be set up according to the situation. . Therefore, it is possible to make it easier for a user who gets into the back of the car to get off the vehicle, and to improve unnecessary driving time and to improve driving efficiency.

Embodiment 2. FIG.
3 and 4 relate to Embodiment 2 of the present invention. FIG. 3 is a block diagram showing the configuration of the elevator control device, and FIG. 4 is a flowchart showing the operation of the elevator control device. 3, the same reference numerals as those in FIG. 1 denote the same or corresponding parts, and detailed description thereof will be omitted as appropriate.

  The landing destination call registration device 1 shown in FIG. 3 is also installed at a landing (not shown) on each floor where the elevator car stops, as in the first embodiment (FIG. 1). The landing destination call registration device 1 is provided with an operation unit such as a destination floor button (not shown) so that a call registration operation specifying a desired destination floor by the user can be accepted.

  When the user operates the landing destination call registration device 1, an operation signal corresponding to the operation content is output from the landing destination call registration device 1 on which the operation is performed. The operation signal output from the landing destination call registration device 1 is input to the group management control device 6. In the second embodiment, a plurality of elevator cars are provided. Then, the group management control device 6 manages and controls the plurality of cars as a group.

  The operations related to the operation of the individual cars are controlled by each of the control devices 7. Each car control device 7 is provided corresponding to each car. Each table control device 7 is a subordinate device of the group management control device 6. Each table control device 7 controls each car under the direction of the group management control device 6. The group management control device 6 includes a call registration unit 3, a getting-off time prediction unit 4, and a car assignment unit 8.

  As in the first embodiment, the call registration unit 3 registers a landing destination call based on an operation to the landing destination call registration device 1. That is, the call registration unit 3 registers a landing destination call based on the operation signal output from the landing destination call registration device 1. The boarding floor of the landing destination call is the floor where the landing destination call registration device 1 to which the operation signal is output is installed. The destination floor of the landing destination call is a floor designated by the user as the destination floor in the operation when the operation signal is output.

  The getting-off time prediction unit 4 predicts the getting-off time when the car stops at the destination floor of the landing destination call. As in the first embodiment, the getting-off time prediction unit 4 includes a determination unit 4a. Then, when there are a plurality of landing destination calls registered by the call registration unit 3, the determination unit 4a is predetermined for each destination floor based on the boarding floor and the destination floor of each of the plurality of landing destination calls. It is determined whether or not the getting-off route unsecured condition is satisfied.

  The getting-off route unsecured condition is the same as in the first embodiment. That is, the first requirement is included in the unsecured conditions for getting off the route. The first requirement is that, for a plurality of registered landing destination calls, the destination floor of a certain landing destination call is another landing destination call that stops after the landing floor of the one landing destination call. It exists between the boarding floor and the destination floor.

  In addition, the second requirement can be further included as the unsecured route getting-off condition. The second requirement is that the number of passengers in the car when arriving at the destination floor of the one landing destination call is greater than or equal to a predetermined number. In this case, the determination unit 4a determines that the getting-off route unsecured condition is satisfied when both the first requirement and the second requirement are satisfied.

  The getting-off time predicting unit 4 predicts the getting-off time at each destination floor using the determination result by the determining unit 4a. In the destination floor where it is determined by the determination unit 4a that the getting-off route unsecured condition has been established, the predicted getting-off time becomes longer than the specified value.

  The car allocating unit 8 performs the car registration for the call registration based on the boarding floor of the landing destination call registered by the call registration unit 3 and the departure floor predicted by the departure time prediction unit 4. Assign. More specifically, the car assignment unit 8 first calculates an evaluation value of each car for a newly registered call. This evaluation value is calculated based on the waiting time of the user at the hall and the required time to the destination floor.

  Next, the car allocating unit 8 penalizes the evaluation value according to the length of the getting-off time predicted by the getting-off time predicting unit 4. Then, the car assignment unit 8 compares the evaluation values of the cars and assigns the car having the best evaluation value to the newly registered call. Therefore, a car having a destination floor that is determined by the determination unit 4a to satisfy the unsecured route condition is less likely to be assigned for call registration.

  The group management control device 6 outputs a response command signal for the call registration to each car control device 7 that controls the car assigned to the call registration by the car assignment unit 8. Receiving this command signal, each vehicle control device 7 controls the operation of the car so as to respond to the call registration.

The operation flow of the elevator control apparatus configured as described above will be described with reference to the flowchart of FIG.
First, in step S <b> 21, the car control device 2 confirms whether or not a new landing destination call is registered by the call registration unit 3. If a new landing destination call is registered, the process proceeds to step S22. If a new landing destination call is not registered, step S21 is repeated until it is registered.

  In step S22, the car assignment unit 8 temporarily assigns one of the assignment candidate cars to the new landing destination call registered in step S21. Then, the process proceeds to step S23.

  In step S23, the determination unit 4a uses the new landing destination call registered in step S21 and the information on the boarding floor and destination floor of the already registered landing destination call for the car temporarily allocated in step S22. Then, it is confirmed whether or not the first requirement of the getting-off route unsecured condition is satisfied. That is, the determination unit 4a determines whether or not the destination floor of the one landing destination call that the user gets on first is between the boarding floor and the destination floor of the other landing destination call that responds later. To do.

  In step S23, when it is determined that the first requirement is not satisfied, the process proceeds to step S27. On the other hand, if it is determined that the first requirement is satisfied, the process proceeds to step S24.

  In step S24, the determination unit 4a confirms whether or not the second requirement of the getting-off route unsecured condition is satisfied for the car temporarily assigned in step S22. That is, the determination unit 4a determines whether or not the number of passengers in the car at the time when the car arrives at the destination floor of the one landing destination call on which the user gets on first is greater than or equal to the reference.

  If it is determined in step S24 that the second requirement is not satisfied, the process proceeds to step S27. On the other hand, if it is determined that the second requirement is satisfied, the process proceeds to step S25.

  In step S25, the getting-off time predicting unit 4 sets the estimated getting-off time on the destination floor of the one landing destination call, on which the user gets first, longer than a specified value. Then, the process proceeds to step S26.

  In step S26, the car allocating unit 8 further adds the predicted getting-off time set in step S25 as a penalty to the comprehensive evaluation value calculated for the temporarily allocated car. Then, the process proceeds to step S27.

  In step S27, the car assignment unit 8 confirms whether or not the comprehensive evaluation value calculation processing has been performed for all assignment candidate cars. If the overall evaluation value calculation process has not been performed for all the allocation candidate cars, the process returns to step S22, and the next allocation candidate car is provisionally allocated and the process proceeds. On the other hand, when the comprehensive evaluation value calculation processing has been performed for all allocation candidate cars, the process proceeds to step S28.

  In step S28, a car having the best overall evaluation value is assigned to a new landing destination call. Then, in accordance with this assignment, each car control device 7 travels to respond to the landing destination call. When step S28 is completed, the series of processing is completed.

  Other configurations and operations are the same as those in the first embodiment, and detailed description thereof is omitted.

  The elevator control device configured as described above is installed at a landing on each floor where the elevator car stops, and a landing destination call registration device 1 that can accept a call registration operation specifying a desired destination floor by a user. And when there are a plurality of landing destination calls registered by the call registration unit 3 based on an operation to the landing destination call registration device 1, and a plurality of landing destination calls, Based on the boarding floor and the destination floor, a determination unit 4a for determining whether or not a predetermined getting-off route unsecured condition is established for each destination floor, and using the determination result by the determination unit 4a, Prediction by the getting-off time prediction unit 4 for predicting the getting-off time required for getting off at the destination floor, and the landing floor of the destination destination call registered by the call registration unit 3 and the destination floor and the getting-off time prediction unit On the basis of the getting-off time, and a to call registration whether your assignment unit 8 assigns the car, the.

  Therefore, the prediction accuracy of the time required for the user to get off at the stop floor can be improved. And since the car allocated to the call is determined by utilizing the predicted value of the getting-off time with improved accuracy, appropriate car allocation can be performed to contribute to the improvement of driving efficiency.

  Further, by adding the estimated getting-off time as a penalty to the evaluation value, it is difficult to make an assignment that is likely to cause a situation in which the getting-off route cannot be secured. Therefore, it is possible to reduce the appearance frequency itself of the situation where it is difficult for the user who gets into the back of the car to get off the car.
