This invention relates to an improvement in a device for managing elevator cars as a group. One of the elevator group management methods is called the allocation method. This assigns when a hall call is registered the best car to answer that call. In order to make this process even more efficient, it has been proposed that the cars be placed on standby in advance in each band. These include: (a) Divide the service floor of the elevator into a plurality of bands each consisting of one floor or a plurality of connected floors, and have the cars stand by distributed in each band. (a) The main floor and specific floors other than the main floor are designated as distributed waiting floors, and the cars are distributed to each distributed waiting floor. However, in either case, if there is not one corresponding waiting car (or more depending on the floor) on the distributed waiting floor, the waiting cars on other floors will be drawn to the nearby waiting floor. Even if there is a car, the car must be run all the way to the waiting floor.
This results in wasteful running and unnecessary power consumption. SUMMARY OF THE INVENTION The present invention aims to improve the above-mentioned drawbacks and provides an elevator group management system that can perform distributed waiting to reduce wasteful running. An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In Figure 1, a is the available car waiting on the 1st floor (the car that has answered all the calls to be serviced) and the car of car A is waiting, and b and c are on the 3rd and 2nd floors, respectively. These are cars No. B and No. C which have just become available cars. In Figure 2, 1Aa is an expected arrival time signal that represents the time required for car a of car a to travel from its current position to the first floor directly. It is calculated from the product of time and the number of floors up to the first floor, and this is already known. 1Ab and 1Ac are the 1st floor expected arrival time signals for cars B and C, 7Aa to 7Ac are the expected 7th floor arrival time signals for cars A to C,
9Aa~9Ac are also the expected arrival time signals on the 9th floor.
In addition to this, expected arrival time signals for the third and fifth floors are also provided, but are not shown. 1B is a determination circuit that determines the floor on which a waiting car is requested;
3B, 5B, 7B, and 9B are also on the 3rd floor, 5th floor, and 7th floor.
Judgment circuit for floor and 9th floor (3rd and 5th floors are not shown), 1Ba is an arithmetic circuit for car a on the 1st floor, 1Ab, 1Bc are arithmetic circuits for car b and c, 3C, 5C, 7C, 9C is 3 each

D, 5D, 7D, 9D are inverter gates, 3
E, 5E, 7E, 9E are AND gates, 1F, 3
F, 5F, 7F, and 9F are the 1st floor, 3rd floor, and 5th floor, respectively.
floor, 7th floor and 9th floor standby car request signal, 1C is 1
Predetermined time signal determined for each floor, 3G, 5
G, 7G, and 9G are the same predetermined time signals for the 3rd, 5th, 7th, and 9th floors, and 11 is the output Z = "O" when input X > input Y, and the output Z = when input X≦input Y. A comparator that becomes "1", 12 is an AND gate, 13 is a NOR gate, 14a is a standby signal that becomes "1" when machine a is in a standby state, and becomes "O" in other states, 14b and 14c are This is also the standby signal for cars B and C. Next, the operation of this embodiment will be explained. Now, the positions of each car a to c are as shown in Figure 1.

分散待機を行わせることができる。[Table] Now, in the first floor determination circuit 1B, the first floor expected arrival time signal 1Aa is 0 seconds and the predetermined time signal 1G is 4 seconds, so the output Z of the comparator 11 becomes "1". Also, since the standby signal 14a is "1",
The output of the AND gate 12 becomes "1". on the other hand,
Since the standby signals 14b and 14c are both "0", the outputs of the arithmetic circuits 1Bb and 1Bc are both "0".
Therefore, the output of the NOR gate 13, that is, the first floor standby car request signal 1F becomes "0". That is,
Since there is already a waiting car a that can arrive at the first floor within the predetermined time, no new request for a waiting car is made. In the determination circuit 9B for the ninth floor, which has the second priority, the expected arrival time signal 9Aa is 16 seconds and the predetermined time signal 9G is 6 seconds, so a comparator (not shown)
The output Z becomes "0", and the output of the arithmetic circuit 9Ba (not shown) becomes "0". On the other hand, special equipment signal 1
Since 4b and 14c are both "0", the outputs of arithmetic circuits 9Bb and 9Bc (not shown) are both "0". Therefore, the output of the ninth floor determination circuit 9B, that is, the ninth floor standby car determination signal 9C becomes "1". Since the first floor standby car request signal 1F is "0" and the output of the inverter gate 9D is "1", the output of the AND gate 9E, that is, 9
The floor standby car request signal 9F becomes "1". Similarly, at this time, the waiting car request signals 5F, 3F, and 7F on the 5th, 3rd, and 7th floors are all "0". As a result, based on the 9th floor standby car request signal 9F, 9 of the available cars b and c that are not on standby are
A standby command to the 9th floor is issued to car b, which is closer to the floor (the circuit is omitted). When the car b travels and reaches the 9th floor and enters the standby state, the standby signal 14b becomes "1". At this time, the expected arrival time of car B is calculated as 16 seconds for the 1st floor, 0 seconds for the 9th floor, 3 seconds for the 5th floor, 12 seconds for the 3rd floor, and 4 seconds for the 7th floor. do. As a result, the 5th floor standby car request signal 5 is generated by the same operation as described above.
Only F is “1”, request signals for other floors 1F, 9F, 3
F and 7F are all "0". Now, the basket c
A standby command to the 5th floor is issued to the car, and the car C travels, arrives at the 5th floor, and waits. Then, the standby signal 14c becomes "1". At this time, assume that the expected arrival time of car c is calculated as 8 seconds for the 1st floor, 8 seconds for the 9th floor, 0 seconds for the 5th floor, 4 seconds for the 3rd floor, and 4 seconds for the 7th floor. , standby car request signal 1F,
9F, 5F, 3F, and 7F are all "0". Then, the final position of each car a to c is
This is shown by the broken line in the figure (the car a is a solid line). In this way, the determination circuits 1B, 9B, 5B,
3B and 7B are used to determine the floor where no car is waiting within a predetermined period of time. Further, the floor with the highest priority is selected and waiting car request signals 1F, 9F, 5F, 3F, and 7F are issued, so that the cars a to c are placed on standby in a distributed manner. In addition, in the embodiment, the determination circuits 1B, 9B, 5
Although the case where B, 3B, and 7B are provided on the 1st floor, 9th floor, 5th floor, 3rd floor, and 7th floor has been described, it is of course possible to provide them on other floors. Further, in the above embodiment, the standby car request signal 1F,
A standby command was issued to have the car wait on a specific floor where 3F, 5F, 7F, and 9F became "1", but
It is not necessarily necessary to have them wait on the above-mentioned specific floor. The robot may be made to wait at any floor as long as it can arrive at the specific floor within a predetermined time. It is clear that this will further reduce wasteful running. As explained above, in this invention, by comparing the expected arrival time of a car to a specific floor and a predetermined time set corresponding to that specific floor, it is possible to determine whether there is a car that can arrive within a predetermined time and is waiting. and if there is no car on standby, a standby command is issued to the available cars according to predetermined conditions so that the cars can arrive at the specific floor within the predetermined time, thereby making the cars stand by in a distributed manner. As a result, it is possible to respond to a hall call on a specific floor within a predetermined time, and moreover, it is possible to perform a distributed standby that reduces wasteful running.
