It is an example of data of a predicted number of passengers table per unit time predicted in one example of the present invention, and its evaluation example. It is an example of data of the predicted number of passengers table per unit time predicted in one example of the present invention, and other evaluation examples. It is a determination processing flow of directionality when arriving toward the final car call according to an embodiment of the present invention.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall configuration diagram of an elevator control device according to an embodiment of the present invention.

  In FIG. 1, 1 is an elevator control device, 2 is a group management control device, 31-33 are elevator control devices of elevators 1-3. 41 to 43 are elevator cars of Units 1 to 3. Reference numerals 51 to 53 denote destination floor registration devices in the car, and reference numerals 61 to 63 denote car position display devices in the car. 81 and 82 are hall call buttons common to each floor floor hall, and 91 to 96 are hall lanterns (also called reservation lamps) provided at the halls of No. 1 to 3 respectively to guide service elevators.

  In the embodiment shown in FIG. 1, the elevator control device 1 in the elevator machine room is composed of a group management control device 2 and a plurality of machine control devices 31 to 33. The elevator car will be described by taking the car 41 as an example. A car call button 51 is provided, and a signal from the car call button 51 is input to the machine control device 31.

  The hall call buttons 81 are provided at the halls on each floor, for example, the 1st floor hall, and these directly input or output signals from the group management control device 2. The car position display device 61 installed in the car 41 also directly inputs and outputs signals from the group management control device 2. Hall lanterns 91 and 94, which are other hall guide devices, are configured to input / output signals to / from the group management control device 2 via the machine control device 31. There are cases where special calls such as wheelchair-only landing calls are installed on the same floor.

  The group management control device 2 sends the signals from the hall calls 81 and 82 to the hall call information collecting unit 21 and the elevator control positions 31 to 33 sent from the unit control devices 31 to 33, the state of the car call, the inside of the car The car information collecting unit 22 collects the congestion level signal of the car, and the traffic information detecting unit 23 determines the current elevator usage status based on the information of the hall call information collecting unit 21 and the car information collecting unit 22. The traffic information detection unit 23 detects a traffic flow pattern and predicts the number of passengers from each floor. Based on the predicted number of passengers, the driving direction determination unit 24 at the time of arrival of the final car call determines what the driving direction at the time of arrival of the final car call is, and transmits it to the machine control devices 31-33.

  FIG. 2 shows an example of contents data of the predicted number of passengers table per unit time predicted by the traffic information detection unit 23 and an example of evaluation of the number of users as a whole building upon arrival at the final car call in one embodiment of the present invention. It is shown.

  The normal pattern A is an example of a pattern having a relatively large number of users in the upper layer part, and the normal pattern B is an example of a pattern having few users in the upper layer part, and these vary depending on the situation of the tenant.

  In the figure, rising (person) is the number of passengers in the upward direction from each floor from 1F to 8F, and falling (person) is the number of passengers in the downward direction from each floor from 9F to 2F. U (n) and D (n) can use the car as a whole building when the car arriving at the final car call toward the nth floor has the direction of ascending and descending. It represents the predicted number of people.

  As for the 2nd floor of the normal A pattern, 5 people at the 2F hall, 3 people on the 3rd floor, 3 people on the 4th floor, It can be evaluated that the number of passengers in the ascending direction of 4 people in 5F, 5 people in 6F, and 5 people in 7F, and the expected number of users U (2) = 25 in the ascending direction that can be used. Similarly, with regard to 3F, since 5 people from the 2nd floor cannot be used, U (3) = 20 people excluding these 5 people. Hereinafter, similarly, the predicted number of users U (4) to U (8) in the ascending direction when the 4F to 8F are given the ascending directionality, respectively, as shown in FIG. (4) = 17, U (5) = 14, U (6) = 10, U (7) = U (8) = 5.

  Similarly, if the predicted number of users D (9) to D (2) in the descending direction is obtained, it is as entered in FIG.

  Therefore, if it is judged whether the direction of use of the elevator as the whole building can be enhanced if the direction of the car arriving at each floor toward the final car call is increased, the normal A pattern in FIG. It can be seen that the directionality should be changed with 5F and 6F separated by a thick line as a boundary. That is, the car that arrives by 2-5F toward the final car call is stopped with the direction of ascending direction, and the car that arrives by 6-8F has the direction of descending direction. If stopped, the possibility of more efficient service to the traffic demand in the building that will occur afterwards increases.

  On the other hand, in the case of the normal B pattern of FIG. 2, since the traffic demand is different, it can be seen that the directionality should be changed with 3F and 4F separated by a thick line in the figure as a boundary. That is, the car arriving at the 2nd and 3rd floor toward the final car call is stopped with the direction of the ascending direction, and the car arriving by 4-8F is provided with the direction of the descending direction. If stopped, the possibility of more efficient service to the traffic demand in the building that will occur later increases.

  In FIG. 2, the traffic demand in the upward direction and the traffic demand in the downward direction have been described separately for easy understanding. However, in an actual elevator, the service is performed in a ring shape in which the elevator car that has been lifted is reversed and lowered on the top floor, and is again turned on the bottom floor. Therefore, in practice, it is desirable to predict the number of users in this ring-shaped service zone.

  FIG. 3 shows another example of the content data of the predicted number of passengers table per unit time predicted by the traffic information detection unit 23 and other predicted users as the entire building upon arrival at the final car call in one embodiment of the present invention. An example is given.

  In this example, the number of users is predicted in the above-described ring-shaped service zone, which will be described along the flow of FIG.

  FIG. 4 is a processing flow in the driving direction determining unit 24 when arriving toward the final car call according to one embodiment of the present invention.

  In FIG. 4, in the process of step 301, the predicted number of users U (n) when arriving in the upward direction is calculated for each floor (n). If it demonstrates in the example of FIG. 3, since the arrival with the directionality of a descent | fall direction cannot be in 1F which is the lowest floor, 109 users of all the users will become the prediction user number U (1). . In 2F, U (2) is obtained as the sum of the number of users in the upward direction from 2F to 8F and the ring-shaped service zone that is inverted on the top floor and the user in the downward direction from 9F to 3F. Similarly, U (3) to U (8) from 3F to 8F are calculated, and the result is stored in the U (n) array.

  In the process of step 302, as in step 301, when the car arriving toward the final car call is given a direction of descending direction, the number of users D (n) is finally calculated for each floor (n). Each time, the result is stored in the D (n) array.

  The U (n) and D (n) arrays in FIG. 3 represent the results calculated in steps 301 and 302 in FIG. The calculation results for the normal A pattern and the normal B pattern are described, respectively. In step 303, the floor to be compared is initialized. n represents a floor.

  Next, in step 304, the values of the nth floor of the U (n) array and the D (n) array are compared.

  If the U (n) array is large, n is increased by 1 in step 305, and the U (n) array and the D (n) array are compared again. When the D (n) array becomes larger in the determination at step 304, the value is transmitted to the elevator. That is, as shown in step 306, the elevator that has received the signal indicating the nth floor, when the destination floor of the final car call is lower than the nth floor, arrives with the direction of the ascending direction, When the car call is a floor higher than the n-th floor, it is made to arrive with a direction of descending direction.

  According to the preferred embodiments of the present invention described above, the arrival direction of the elevator with respect to the final car call can be determined so as to increase the use efficiency of the elevator for the entire building.
