technical field

The present invention relates to assigning the hall call that occurs to the most suitable elevator among a plurality of elevators for the hall call when the hall button is pressed, and making the assigned elevator serve the hall where the aforementioned hall call occurs Group management control device for elevators.

Background technique

Conventionally, when a plurality of elevators are installed side by side, group management operation is usually performed. One of such group management operations is the allocation method, but when registering a hall call, it directly calculates and assigns an evaluation value to each car, and assigns the car with the best evaluation value as the car to be served. Only the assigned car is made to respond to the aforementioned landing call, which can improve the operating efficiency and shorten the waiting time of the landing.

The allocation evaluation value of the above-mentioned allocation system is calculated from the viewpoint of which car is most suitable to be allocated if the current situation progresses as it is. That is to say, based on the current car position and car direction, and the currently registered landing calls and car calls, the arrival time, which is the predicted value of the time required to sequentially respond to the aforementioned landing calls and arrive at each floor landing, is obtained. Predicted time, and the elapsed time of the landing call, that is, the continuation time, and further add the aforementioned arrival forecast time and the aforementioned continuation time to calculate all the currently registered landing prediction waiting times. Then, the sum of these predicted waiting times or the sum of the squared values of the predicted waiting times is set as an allocation evaluation value by the allocation evaluation value calculation means, and an allocation command is output to the car whose allocation evaluation value is the smallest.

As such a group management method of elevators, there are the following conventional technologies.

(A) Predict the position of the car after a predetermined time, determine the waiting floor, and make the empty car stand by (refer to Japanese Patent Publication No. 7-25491).

(B) Allocation and standby are performed corresponding to the intervals between the cars after a predetermined time (refer to Japanese Patent Application Publication No. 7-72059).

However, the aforementioned conventional technology has the following problems.

That is, in the aforementioned (A), the standby operation has a substantial effect only when the user is idle.

Therefore, in order to solve the aforementioned problems, an object of the present invention is to provide an elevator group management control device capable of reducing service unevenness and effectively and well performing group management by equalizing the possible service time of each floor.

The best way to practice the invention

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

Fig. 1 shows a basic configuration diagram of an elevator group supervisory control device related to the present invention.

As shown in Figure 1, the group management control device 2 for group management of a plurality of cars is connected to the car control device 1 for controlling the cars to send and receive data, and perform a hall call by operating the hall button 4 According to the landing call registration, the allocation evaluation value for selecting and allocating the car that should be served is calculated, and according to the allocation evaluation value, the car control device 1 corresponding to the most suitable car is allocated, and the car is sent. The distribution output of the box to serve at the landing where the aforementioned landing call occurred. In addition, although only one car control device 1 connected to the group supervisory control device 2 is shown in FIG. 1 , actually a plurality of them may be connected.

Embodiment 1

Fig. 2 is for explaining the group supervisory control device of the elevator related to Embodiment 1 of the present invention, and shows the control function structure diagram of CPU 2A as the control unit of the group supervisory control device 2 shown in Fig. 1 in block diagram.

In Fig. 2, 10 is a well-known hall call registration device that registers a hall call according to the operation of the hall button 4 provided on the floor boarding point, and 11 is a well-known distribution evaluation value computing device, and the distribution evaluation value device According to the current car position and car direction and the currently registered landing calls and car calls, the estimated arrival time required for the car to respond to the landing calls in sequence until reaching the landings of each floor is obtained, Adding the estimated arrival time and the continuation time to the continuation time of the hall call after registration, calculates the predicted waiting time of all hall calls currently registered, and calculates the sum of these predicted waiting times or the predicted waiting time The sum of the square values of , is set as the allocation evaluation value, and 12 is a well-known car position prediction device that predicts the car position after a predetermined time from the current car position.

13 is a possible service time distribution calculation device for calculating the possible service time of each floor based on the car position predicted by the aforementioned car position prediction device 12, that is, the distribution of the predicted arrival time of the car that can answer the hall call the earliest, 14 is an allocation correction value calculating means for calculating an allocation correction value for correcting an allocation evaluation value based on the possible service time distribution calculated by the possible service time distribution calculation means 13, and 15 is an allocation correction value calculation means based on the above-mentioned landing call registration. The landing call registered by the device 10, the distribution evaluation value calculated by the above-mentioned distribution evaluation value computing device 11 and the distribution correction value calculated by the distribution correction value computing device 14, select the car with the smallest distribution evaluation value as the most suitable car And the car distribution device for distribution receives the car control device 1 from the car distribution output of the car distribution device 15, responds to it, and controls the elevator car 5 that includes the corresponding drive control device 3 .

Similar to the conventional examples, in the elevator group management control device according to the first embodiment including the above-mentioned structure, when the hall button is pressed, for the hall call, the hall call that occurs is allocated to the most suitable hall call from a plurality of elevators. The elevator makes the assigned elevator perform service at the landing where the aforementioned landing call occurs, but the place described later is different.

That is to say, referring to the relationship diagrams of calls and car positions shown in FIGS. The explanatory diagram of the possible service time of each floor in the figure, the new operation related to the first embodiment including the above-mentioned structure will be described according to the flow chart shown in Fig. 3 as the content of the control function of the CPU 2A.

As shown in Figure 4, cars A, B, and C are used as elevator cars 5 managed by the group, and car A is on standby on the first floor with the door closed, and car B is on the fifth floor as shown by the arrow to have an upward distribution. When the car C runs in the upward direction on the 9th floor with a car call as shown by the circle, it is registered as a hall call with an upward direction on the 4th floor as shown by the triangle. The allocation operation will be described as an example.

In the flow chart shown in Fig. 3, at first, in step S11, carry out the inspection of whether to press the landing button 4, under the situation of not pressing the landing button 4, do nothing and finish processing, press the landing button In the case of 4, proceed to step S12, and use the hall call registration device 10 to register the hall call. After registering the landing call, enter step S13, for the occasion that the landing call in the upward direction of the 4th floor is assumed to be allocated to the cars A-C, the car position prediction device 12 is used to calculate the current car position of each car. The position of the car after the lapse of a predetermined time is predicted respectively.

For example, FIG. 5 shows the car position state of cars A-C after a predetermined time (in the case of 10 seconds as the predetermined time) when hall calls in the upward direction of 4 floors are assumed to be allocated to car A. Similarly, FIG. 6 shows the car position state after a predetermined time when the car B is assumed to be allocated, and FIG. 7 shows the car position state after a predetermined time when the car C is assumed to be allocated.

After predicting the position of the car as described above, proceed to step S14, and utilize the possible service time distribution calculation device 13 to calculate the possible service time of each floor (the time until the car with the fastest response arrives). For example, if it takes 2 seconds for the car to enter a floor and stay on each floor for 10 seconds, it will be calculated as the car passing through all the landings in sequence, and the car with no direction will be taken as the floor from the car position. Run directly to each landing, and calculate the time until the car can respond.

According to this condition, calculate the possible response time of each car car position state shown in Figure 5, then the response time of car A to each floor is as shown in Figure 8, and the response time of car B to each floor As shown in FIG. 9 , the response time of the car C to each floor is shown in FIG. 10 .

The distribution of the possible service time of each floor calculated from the above results is shown in FIG. 11 . Similarly, for Fig. 6 and Fig. 7, the distribution of the possible service time of each floor can also be calculated as shown in Fig. 12 and Fig. 13 .

After calculating the distribution of the possible service time of each floor, proceed to step S15, take out the maximum time from the possible service time calculated by the distribution correction value computing device 14, and use it as the distribution correction value of each car. In this case, the allocation correction value of car A is 16, the allocation correction value of car B is 8, and the allocation correction value of car C is 18.

After the allocation correction value is calculated in step S15, the process proceeds to step S16, and the allocation evaluation value computing device 11 calculates the allocation evaluation value of each car. That is, as we all know, the allocation evaluation value is based on the current car position and car direction, as well as the currently registered landing calls and car calls, and calculates the required time for the car to respond to the aforementioned landing calls in sequence until reaching the landings of each floor. Arrival forecast time, and the continuation time elapsed after landing call registration, add the aforementioned arrival forecast time and the aforementioned continuation time, and then calculate all the currently registered landing forecast waiting times, and calculate the sum or forecast of these forecast waiting times The sum of the square values of the waiting time is used as the allocation evaluation value.

After the allocation evaluation value is calculated in step S16, enter into step S17, use the car allocation device 15 to add the allocation correction value and the allocation evaluation value, select the car with the smallest allocation evaluation value as the most suitable car, and output the allocation signal . For example, if car A is 6, car B is 10, and car C is 20 as the distribution evaluation value of each car, the distribution correction value is added to this distribution evaluation value, then car A is 22 , car B is 18, car C is 38, select and assign car B as the most suitable car.

Therefore, adopting embodiment 1, then the possible service time (difference between the maximum predicted time of arrival and the minimum predicted time of arrival) of each floor is reduced, by means of the possible service time of each floor tends to be even, can reduce the inhomogeneity of service and Improve service.

Explanatory diagram of possible service time, diagram of relationship between call and car position shown in FIG. 22, diagram of possible service time for each floor shown in FIG. 23, relationship diagram of call and car position shown in FIG. , and the explanatory diagram of the possible service time of each floor shown in FIG. 25, the operation related to Embodiment 2 having the above-mentioned structure is described according to the flow chart shown in FIG. 15 according to the content of the control function of CPU2A.

As shown in Figure 16, cars A, B, and C are used as elevator cars 5 managed by the group, and car A is on the 1st floor with the door closed and waiting, and car B is on the 9th floor as shown in the circle to have an upward distribution. When the state of is running in the upward direction and the car C is on standby with the door closed on the 9th floor, the operation of setting the standby car and the standby floor and making the standby car stand by at the standby floor will be described.

In the flowchart shown in FIG. 15, first, in step S21, the car position predicting device 12 predicts the car position after a predetermined time elapses from the current position of each car. For example, if the predetermined time is set to 10 seconds, FIG. 17 shows the car position in a state after 10 seconds have elapsed from the car position state shown in FIG. 16 .

After the car position is predicted, proceed to step S22, and use the possible service time distribution calculation device 13 to calculate the possible service time of each floor. For example, if it takes 2 seconds for the car to enter a floor, and 10 seconds for each stop, the car will go through all the landings in sequence for calculation, and the car without direction will run directly from the floor where the car is located. To each landing, calculate the time until the car can respond.

According to this condition, the possible response time of each car shown in Figure 17 in the position state of the car is calculated, then the response time of car A to each floor is as shown in Figure 18, and the response time of car B to each floor As shown in FIG. 19 , the response time of the car C to each floor is shown in FIG. 20 .

The distribution of the possible service time (the time until the car that can respond the earliest) of each floor calculated from the above results is shown in FIG. 21 .

After calculating the distribution of the possible service time of each floor, enter in step S23, extract the maximum floor from the possible service time calculated by the waiting floor setting device 16 as the empty car waiting floor. In this case, the empty car standby floor is five floors.

After setting the empty car standby floor in step 23, enter in step 24, utilize empty car detecting device 17 after the end of responding to all calls, to the car that is not car call and is not the hall call that is allocated simultaneously. The car is detected as an empty car. In this case, it is detected that the cars A and C are empty cars.

After an empty car is detected in step S24, the process proceeds to step S25, and the waiting car setting device 18 is used to set a waiting car on an empty car waiting floor from the empty cars. The setting method is to calculate the possible service time distribution of each floor in the case of an empty car standby floor assuming that an empty car is on standby. For occasions where the car is small, it is used as a standby car. For example, FIG. 22 shows the car position status when an empty car A is waiting on an empty car standby floor, FIG. 23 shows the distribution of possible service times, and FIG. Figure 25 shows the distribution of the possible service time for the position status of the car when the car is on standby at the floor. Therefore, since the maximum possible service time when the car A is placed on standby is 8 and the maximum possible service time for the car C is 6, the car C is set as the waiting car.

After the waiting car is set in step S25, the process proceeds to step S26, and the empty car C set by the car allocating device 15 is placed on standby on the fifth floor of the empty car waiting floor.

Therefore, according to the second embodiment, the possible service time for each floor can be made uniform, and the service can be improved by reducing service unevenness.

Implementation form 3

Fig. 26 is a block diagram showing the control function structure of CPU 2A as the control device of the group supervisory control device 2 shown in Fig. 1, for explaining the elevator group supervisory control device according to Embodiment 3 of the present invention.

In FIG. 26, the same reference numerals are assigned to the same parts as those in the first embodiment shown in FIG. 2, and description thereof will be omitted. The car allocating device 15 of this embodiment sets the return car and the return floor according to the distribution of the possible service time calculated by the possible service time distribution calculation device 13, and returns the set return car to the return floor. The loopback output is sent to the corresponding car control device 1, and the car control device 1 of the car receiving the loopback output responds to it and controls the elevator car 5 including the drive control device 3.

Next, refer to the relationship diagrams of calls and car positions shown in Figures 28 and 29, the explanatory diagrams of the possible response times of cars on each floor shown in Figures 30 to 31, and the possible response times of cars on each floor shown in Figure 32. Explanatory diagram of possible service time, diagram of relationship between call and car position shown in FIG. 33, diagram of possible service time for each floor shown in FIG. , and the explanatory diagram of the possible service time of each floor shown in FIG. 36, the operation related to Embodiment 3 with the above-mentioned structure is described according to the flow chart shown in FIG. 27 of the content of the control function of CPU2A.

As shown in Figure 28, car A, B, C, as the elevator car 5 managed by the group, runs in the upward direction in the state that car A has a car call to the 10th floor as shown in a circle. When box B is running upward with a car call to the 9th floor as indicated by a circle, the operation of setting the return car and the return floor and forcibly stopping the return car on the return floor will be described.

In the flowchart shown in FIG. 27, first, in step S31, the position of the car is predicted by the car position predicting device 12 after a predetermined time elapses from the current position of each car. For example, if the predetermined time is set to 10 seconds, FIG. 29 shows the car position in a state after 10 seconds have elapsed from the car position state shown in FIG. 28 .

After the car position is predicted in step S31, the process proceeds to step S32, and the possible service time distribution calculation means 13 is used to calculate the possible service time of each floor. For example, if it takes 2 seconds for the car to enter a floor, and 10 seconds for each stop, the car will go through all the landings sequentially for a week, and the car without direction will run directly from the floor where the car is located. To each landing, calculate the time until the car can respond.

If the possible response time of each car in the car position state shown in Figure 29 is calculated according to this condition, the response time of car A to each floor is as shown in Figure 30, and the response time of car B to each floor is as shown in Figure 30. The response time is shown in Figure 31.

The distribution of the possible service time (the time until the car that can respond the earliest) of each floor calculated from the above results is shown in FIG. 32 .

After calculating the distribution of the possible service time of each floor in step S32, enter in the step S33, utilize the car allocating device 15 to carry out the inspection whether the time that the possible service time is the maximum exceeds the designated time.

Here, when not exceeding the designated time, end the processing, and when exceeding the designated time, proceed to step S34, utilize the car setting device 15 to set the return floor and the return car, and make the return car return (forced) stop) to the loopback floor. For example, the return floor is set to the floor where the car is located at the current moment (the state of Figure 28), and the return car is set to be returned to the floor, and the possible service time after the specified time is the maximum and less time car. For example, when the car A is returned (forced to stop), the return floor is the first floor.

FIG. 33 shows the position status of the car during the predetermined time (when 10 seconds is used as the predetermined time) at this time, and FIG. 34 shows the distribution of possible service times. Similarly, when the empty car B is forcibly returned, the return floor is two floors. FIG. 35 shows the position status of the car after a predetermined time at this time, and FIG. 36 shows the distribution of possible service times.

Therefore, the possible service time when car A is forced to return is the maximum time of 32 seconds, car B is 36 seconds, car A is set as the return car, and the return car is forcibly stopped at the return floor ( 1 floor).

Therefore, adopt present embodiment 3, then can reduce to the difference of the possible service time of each floor (the difference of maximum arrival prediction time and minimum arrival prediction time), by making the possible service time to each floor uniform, reduce the service delay. Uneven to improve service.

Embodiment 4

Fig. 37 is for explaining the elevator group supervisory control device according to Embodiment 4 of the present invention, and is a block diagram showing the control function structure of CPU 2A as the control unit of the group supervisory control device 2 shown in Fig. 1 .

In FIG. 37, the same reference numerals are assigned to the same parts as those in the first embodiment shown in FIG. 2, and description thereof will be omitted. As new reference numerals, 19 is a passenger number prediction device for predicting the number of passengers on each floor, and 20 is a passenger distribution calculation device for calculating passenger distribution distribution based on the passenger number predicted by the above-mentioned passenger number prediction device 19.

The allocation correction value calculation means 14 of the fourth embodiment calculates the allocation correction for correcting the allocation evaluation value based on the possible service time distribution from the possible service time distribution calculation means 13 and the passenger occurrence distribution from the passenger occurrence distribution calculation means 20. In addition, the car allocating device 15 is based on the hall call registered by the hall call registration device 10, the distribution evaluation value calculated by the distribution evaluation value computing device 11 and the distribution correction value calculated by the above-mentioned distribution correction value computing device 14, Select the car with the smallest allocation evaluation value as the most suitable car and allocate it, and the car control device 1 of the car receiving the allocation output from the car allocation device 15 responds to it and controls the corresponding drive control device. 3 elevator cars 5.

Next, referring to the relationship diagrams of calls and car positions shown in Fig. 4 and Fig. 7, the explanatory diagrams of the possible response times of cars on each floor shown in Figs. The explanatory diagram of the possible service time of each floor, the explanatory diagram showing the number of passengers on each floor shown in Fig. 39, and the explanatory diagram of the comprehensive waiting time of each floor shown in Figs. The operation related to Embodiment 4 will be described in accordance with the flow chart shown in FIG. 38 which is the content of the control function of the CPU 2A.

As shown in Figure 4, cars A, B, and C are used as elevator cars 5 managed by the group, and car A is on standby on the first floor with the door closed, and car B is on the fifth floor as shown by the arrow to have an upward distribution. When the state is running in the upward direction, and the car C is running in the upward direction in the state of having a car call to the 9th floor as shown by the circle, the hall call of the upward direction is registered on the 4th floor as shown by the triangle. Using the case as an example, the distribution operation will be described.

In the flow chart shown in Fig. 38, at first, in step S41, carry out the inspection of whether to press hall button 4, if not press hall button 4, do nothing and finish processing, press hall button 4 In this case, proceed to step S42, and use the hall call registration device 10 to register the hall call.

In step S42, after logging in the landing call, enter step S43, assume that the landing call in the upward direction of the 4 floors is allocated to the cars A-C, and use the car position prediction device 12 to predict the current position of each car respectively. Car position The position of the car after the specified time has elapsed.

For example, FIG. 5 shows the car position state after a predetermined time (when 10 seconds is used as the predetermined time) of the car A-C when the hall call in the upward direction of the 4th floor is assumed to be assigned to the car A. Similarly, FIG. 6 shows the car position state after a predetermined time when it is assumed to be assigned to car B, and FIG. 7 shows the position state of the car after a predetermined time when it is assumed to be assigned to car C.

After predicting the position of the car as described above, proceed to step S44, and utilize the possible service time distribution calculating device 13 to calculate the possible service time of each floor (the time until the car that can respond the earliest arrives). For example, if it takes 2 seconds for the car to enter a floor, and 10 seconds for each stop, the car will go through all the landings sequentially for a week, and the car without direction will run directly from the floor where the car is located. To each landing, calculate the time until the car can respond.

Calculate the possible response time of each car in the car position state shown in Figure 5 according to this condition, then the response time of car A to each floor is as shown in Figure 8, and the response time of car B to each floor The time is shown in FIG. 9 , and the response time of the car C to each floor is shown in FIG. 10 .

The distribution of the possible service time of each floor calculated from the above results is shown in FIG. 11 . Similarly, for Fig. 6 and Fig. 7, the distribution of the possible service time of each floor can also be calculated as shown in Fig. 12 and Fig. 13 .

After calculating the distribution of the possible service time of each floor, enter in step S25, utilize the passenger occurrence number forecasting device 19, predict the passenger occurrence number that will take place in the future from the passenger occurrence number of each floor in the past. For example, assuming that the number of passenger occurrences of the previous day is as shown in FIG. 39 , it is predicted that the number of passenger occurrences of today is the same as that of the previous day, and FIG. 39 shows the same number of passenger occurrences of the previous day.

After the number of passenger occurrences is predicted in step S45, the process proceeds to step S46, and from the number of passenger occurrences predicted by the passenger occurrence number distribution calculation device 20, the distribution of passenger occurrences on each floor is calculated.

After the passenger occurrence distribution is calculated in step S46, enter into step S47, utilize the distribution correction value calculation device 14, by means of the possible service time calculated by the possible service time distribution calculation device 13 and the passenger occurrence distribution calculation device 20 and the passenger occurrence distribution (The number of passenger occurrences on each floor) is multiplied to obtain the total waiting time of each floor as a result of the multiplication, and the largest value is taken out therefrom as an allocation correction value. For example, assume that the calculated passenger occurrence distribution is the result shown in FIG. 39 . Assuming the possible service time shown in Figure 11 and the passenger occurrence distribution shown in Figure 39 when the car is assigned to the car A, the integrated waiting time of each floor when it is assumed to be assigned to the car A is shown in Figure 40.

As a result, the allocation correction value of car A is 4800. Similarly, the overall waiting time of each floor of the car B at this time is shown in FIG. 41 , and the allocation correction value is 400. The comprehensive waiting time of each floor of the car C is shown in Fig. 42, and the distribution correction value is 3600.

After the allocation correction value is calculated in step S47, the process proceeds to step S48, and the allocation evaluation value computing device 11 is used to calculate the allocation evaluation value of each car. After calculating the allocation evaluation value, enter step S49, using the allocation evaluation value from the allocation evaluation value calculation device 11 and the allocation correction value from the allocation correction value calculation device 14, the car allocation device 15 selects the most suitable car for allocation evaluation. box, and output the distribution. For example, when the distribution evaluation value calculated by each car is 500 for car A, 1000 for car B, and 300 for car C, the distribution correction value is added to this distribution evaluation value, and car A is 5300, and car C is 300. Car B is 1400, and car C is 9300. Choose car B as the most suitable car and allocate it.

Therefore, according to Embodiment 4, the service can be performed in accordance with the ratio of the predicted number of passenger occurrences, and the average waiting time can be shortened.

Embodiment 5

Fig. 43 is a block diagram showing the control function structure of CPU 2A as the control device of the group supervisory control device 2 shown in Fig. 1, for explaining the elevator group supervisory control device according to Embodiment 5 of the present invention.

In FIG. 43, the same reference numerals are assigned to the same components as those of Embodiment 2 shown in FIG. 14 and Embodiment 4 shown in FIG. 37, and description thereof will be omitted. The waiting floor setting device 16 of the fifth embodiment sets a waiting floor for waiting an empty car based on the possible service time distribution from the possible service time distribution calculating device 13 and the passenger occurrence distribution from the passenger occurrence distribution calculating device 20 described above. In addition, the standby car setting device 18 sets the standby car according to the output of the empty car detection device 17 and the standby floor setting device 16, and the standby output of the car distribution device 15 is controlled by the aforementioned standby car setting device. The car set at 18 waits on the waiting floor set by the aforementioned waiting floor setting device 16, and the car control device 1 receiving the waiting output car responds to it and controls the corresponding driving control device 3 The elevator car 5.

Next, refer to the relationship diagrams of calls and car positions shown in Figures 16 and 17, the explanatory diagrams of the possible response times of cars on each floor shown in Figures 18 to 20, and the possible response times of cars on each floor shown in Figure 21. Explanatory diagram of possible service time, relational diagram of call and car position shown in FIG. 45, explanatory diagram of possible service time for each floor shown in FIG. 46, relational diagram of call and car position shown in FIG. , the explanatory diagram of the possible service time of each floor shown in FIG. 48 and the explanatory diagram of the comprehensive waiting time of each floor shown in FIGS. The content of the control function of the CPU 2A, that is, the flowchart shown in FIG. 44 will be described.

As shown in Figure 16, cars A, B, and C are elevator cars 5 managed by the group, and car A waits with the door closed on the first floor, and car B has a car facing the ninth floor as indicated by a circle. When the state of the call is running in the upward direction and the car C is on standby with the door closed on the 9th floor, the operation of setting the standby car and the standby floor and making the standby car stand by on the standby floor will be described.

In the flowchart shown in FIG. 44, first, in step S51, the position of the car is predicted by the car position predicting device 12 after a predetermined time elapses from the current position of each car. For example, FIG. 17 shows the car position after 10 seconds from the car position state shown in FIG. 16 .

After the car position is predicted, proceed to step S52, and use the possible service time distribution calculation device 13 to calculate the possible service time of each floor. For example, if it takes 2 seconds for the car to enter a floor, and 10 seconds for each stop, the car will go through all the landings sequentially for a week, and the car without direction will run directly from the floor where the car is located. To each landing, calculate the time until the car can respond.

If the possible response time of each car in the car position state shown in Figure 17 is calculated according to this condition, the response time of car A to each floor is as shown in Figure 18, and the response time of car B to each floor is as shown in Figure 18 . The response time is shown in FIG. 19 , and the response time of the car C to each floor is shown in FIG. 20 .

The distribution of the possible service time (the time until the car that can respond the earliest) of each floor calculated from the above results is shown in FIG. 21 .

After calculating the possible service time distribution of each floor in step S52, enter in step S53, utilize the passenger occurrence number prediction device 19, predict the passenger occurrence number that considers future generation from the passenger occurrence number of each floor in the past.

After the number of passenger occurrences is predicted in step S53, proceed to step S54, and use the passenger occurrence distribution device 20 to calculate the distribution of passenger occurrences on each floor from the number of passenger occurrences predicted by the passenger occurrence number prediction device 19.

After the passenger occurrence distribution is calculated in step S54, enter into step S55, use the waiting floor setting device 16, by means of the possible service time calculated by the possible service time distribution calculation device 13 and the passenger occurrence distribution calculation device 20 to calculate The passenger occurrence distribution of is multiplied to obtain the comprehensive waiting time of each floor as a result of the multiplication, and the floor with the longest time is taken out as the empty car waiting floor. For example, the calculated passenger occurrence distribution is the result shown in FIG. 39 . At this time, the comprehensive waiting time of each floor is shown in FIG. 49 . Therefore, the empty car standby floor in this case is 4 floors.

After setting the empty car standby floor in step S55, enter in step S56, and utilize empty car detection device 17, end for all call responses, detect be not car call and simultaneously be not the hall call that is distributed The car is used as an empty car. In this case, it is detected that the cars A and C are empty cars.

After detecting an empty car in step 56, proceed to step S57, utilize the waiting car setting device 18 to set an empty car to a waiting car on a waiting floor from the empty cars. The setting method is to multiply the possible service time distribution of each floor when the empty car is waiting on the empty car standby floor and the passenger occurrence distribution, calculate the comprehensive waiting time of each floor, and set the time when the comprehensive waiting time is the largest The car that is smaller than the case of not waiting and smaller than the case of putting other cars on standby is used as the waiting car. For example, FIG. 45 shows the car position status when an empty car A is waiting at an empty car standby floor, FIG. 46 shows the distribution of possible service times, and FIG. 50 shows the overall waiting time. In addition, FIG. 46 shows the car position status when an empty car C is waiting at an empty car standby floor, FIG. 48 shows the distribution of possible service times, and FIG. 51 shows the overall waiting time.

Therefore, the total waiting time when the car A is on standby is 1800, and the car C is 400, and the car C is set as the waiting car. After setting the waiting car, proceed to step 58, and utilize the car allocating device 15 to make the set empty car C stand by at the empty car waiting floor (fourth floor).

Therefore, according to Embodiment 5, the service can be performed in accordance with the ratio of the predicted number of passenger occurrences, and the average waiting time can be shortened.

Embodiment 6

Fig. 52 is for explaining the group supervisory control device of an elevator according to Embodiment 6 of the present invention, and shows a block diagram of the control function structure of CPU 2A as the control unit of the group supervisory control device 2 shown in Fig. 1 .

In FIG. 52, the same reference numerals are assigned to the same parts as those in the third embodiment shown in FIG. 26 and the fourth embodiment shown in FIG. 37, and their descriptions will be omitted. The car allocating device 15 of the present embodiment 6 sets the return car and the return floor according to the distribution of the possible service time from the possible service time distribution calculation device 13 and the passenger occurrence distribution from the aforementioned passenger occurrence distribution calculation device 20, and receives the return car and the return floor. The car control device 1 of the car of the feedback output of the car distribution device 15 responds to it and controls the elevator car 5 including the corresponding drive control device 3 .

Next, refer to the relationship diagrams of calls and car positions shown in Figure 28 and Figure 29, the explanatory diagrams of the possible response times of cars on each floor shown in Figure 30 and Figure 31, and the diagrams of each floor's response time shown in Figure 32. Explanatory diagram of possible service time, diagram of relationship between call and car position shown in FIG. 33, diagram of possible service time for each floor shown in FIG. , the explanatory diagram of the possible service time of each floor shown in FIG. 36 and the explanatory diagram of the comprehensive waiting time of each floor shown in FIGS. The content of the control function of the CPU 2A, that is, the flowchart shown in FIG. 53 will be described.

As shown in Figure 28, car A, B are as the elevator car 5 managed by the group, and car A has the state of calling to the car on the 10th floor as shown in a circle and runs in the upward direction, and car B is like a circle When the state with the car call to the 9th floor is running in the upward direction, the operation of setting the return car and the return floor and making the return car forcibly stop on the return floor will be described.

In the flowchart shown in FIG. 53, first, in step S61, the position of the car is predicted by the car position predicting device 12 after a predetermined time elapses from the current position of each car. For example, FIG. 29 shows the car position in a state after 10 seconds have elapsed from the car position state shown in FIG. 28 .

After the position of the car is predicted in step S61, proceed to step S62, and use the possible service time distribution calculation device 13 to calculate the possible service time of each floor. For example, if it takes 2 seconds for the car to enter a floor, and 10 seconds for each stop, the car will go through all the landings in sequence for calculation, and the car without direction will run directly from the floor where the car is located. To each landing, calculate the time until the car can respond.

If the possible response time of each car in the car position state shown in Figure 29 is calculated according to this condition, the response time of car A to each floor is as shown in Figure 30, and the response time of car B to each floor is as shown in Figure 30. The response time is shown in Figure 31.

The distribution of the possible service time (the time until the car that can respond the earliest) of each floor calculated from the above results is shown in FIG. 32 .

After calculating the possible service time distribution of each floor in step S62, enter in step S63, utilize the passenger occurrence number prediction device 19, predict the passenger occurrence number that considers future generation from the passenger occurrence number of each floor in the past in the past.

After the number of passenger occurrences is predicted in step S63, proceed to step S64, and use the passenger occurrence distribution device 20 to calculate the distribution of passenger occurrence on each floor from the number of passenger occurrences predicted by the passenger occurrence number prediction device 19.

After the passenger occurrence distribution is calculated in step S64, enter in step S65, utilize the car allocating device 15, compare the possible service time calculated by the possible service time distribution calculation device 13 and the passenger occurrence distribution calculated by the passenger occurrence distribution calculation device 20 After multiplication, the integrated waiting time is calculated. For example, the calculated passenger occurrence distribution is the result shown in FIG. 39 . The combined waiting time is shown in Figure 54.

After the integrated waiting time is calculated in step S65, the process proceeds to step S66, and utilizes the car allocating device 15 to check whether the maximum value of the integrated waiting time exceeds a specified value. Here, if the specified value is not exceeded, the processing is terminated, and if the specified value is exceeded, step S67 is entered to set the return floor and the return car, and the return car is forcibly stopped on the return floor.

For example, Fig. 39 shows the calculated passenger occurrence distribution. Assuming that the return floor setting is the floor where the car is at the current moment, the possible service time when the return car is set to return to this floor and the passenger occurrence distribution are multiplied The smaller car among the maximum values of , the return floor in the case of forced return car A is 1 floor. In addition, FIG. 33 shows the car position status at this time, FIG. 34 shows the distribution of possible service times, and FIG. 55 shows the integrated waiting time.

Similarly, the return floor in the case of forcibly returning the empty car B is 2 floors. In addition, FIG. 35 shows the car position status at this time, FIG. 36 shows the distribution of possible service times, and FIG. 56 shows the integrated waiting time.

Therefore, the maximum value of the comprehensive waiting time in the case of forced return car A is 3600, and that of car B is 10800. Set car A as the return car, and force the return car (A) to stop at the return floor (1 floors).

Therefore, according to Embodiment 6, service can be performed in accordance with the ratio of the predicted number of passenger occurrences, and the average waiting time can be shortened.

As a new reference numeral, 21 is a car dwell time calculating device for calculating the dwell time of each car on each floor. The allocation correction value calculation device 14 of the seventh embodiment is based on the passenger occurrence distribution from the passenger occurrence distribution device 20 and the passenger occurrence distribution from the aforementioned car. The car residence time of each floor of the car residence time calculation device 21 calculates the distribution correction value used to correct the distribution evaluation value. The allocation evaluation value computed by the evaluation value calculation means 11 and the allocation correction value calculated by the allocation correction value calculation means 14 are used to select the car with the smallest allocation evaluation value as the most suitable car and allocate it. The car control device 1 of the car that distributes the output of 15 responds to it and controls the elevator car 5 including the drive control device 3 .

Fig. 7 shows the car position state after a predetermined time when it is assumed that the car is allocated to car C. In addition, the car stay ratio (number of passenger occurrences per car stay time on average) for each floor is calculated by dividing the passenger occurrence distribution at this time by the car stay time. In this car stop ratio, the value with the largest ratio is taken out of the floors excluding the floor where the car stays, and is used as the correction value for each car allocation. For example, assuming that the passenger occurrence distribution at this moment is as shown in Figure 39, and the car residence time distribution is as shown in Figure 59, then the car residence ratio of each floor at this time is as shown in Figure 60.

Therefore, the allocation correction value for the car A is the maximum value 3 among the floors excluding the floors (4th floor up, 5th floor up, 9th floor up, down) where the car stays. Likewise, the allocation correction value for car B is 6, and the allocation correction value for car C is 7.

After the allocation correction value is calculated in step S76, the process proceeds to step S77, and the allocation evaluation value computing device 11 is used to calculate the allocation evaluation value of each car.

After the distribution evaluation value is calculated in step S77, proceed to step S78, and use the car allocation device 15, and use the distribution evaluation value and distribution correction value to select the car with the most suitable distribution evaluation value and output the distribution signal. For example, if the calculated allocation evaluation values for each car are 5 for car A, 9 for car B, and 11 for car C, then car A is selected as the most suitable car and assigned.

Therefore, according to the present embodiment 7, the service is performed according to the ratio of the number of passengers and the car stay time, and the improvement of the service can be obtained.
