Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly to a control method for connecting a plurality of elevators.

[0002]

2. Description of the Related Art Conventionally, this type of technique is disclosed in
As disclosed in Japanese Patent No. 47-44755, the one that calls in the local elevator before the arrival of the shuttle elevator, and in the Japanese Patent Laid-Open No. 3-98963, a transit switch is provided in the car to make a car call to the transit floor. There is a system that calls the hall on the connecting floor to simplify the switch operation and shorten the waiting time. This allows the transit passengers to call up the local elevators to transit when they arrive at the transit floor, which makes it possible to reduce the waiting time for transit passengers and the number of button operations. .

[0003]

According to the above conventional technique,
Although it is possible to shorten the waiting time for transit passengers and simplify the button operation, normally, the travel distance from the shuttle elevator to the local elevator to be transferred is 10-2.
It is often 0 m or more, and it takes about 12 to 18 seconds to move during this period even if the user walks without stagnation.
In the method of calling in advance, the elevator is kept waiting during this period. Therefore, the overall efficiency may be significantly reduced. In addition, on the middle floor of the building, there is an elevator transfer floor called Sky Lobby, where you can go to the Sky Lobby directly by the shuttle elevator from the lobby floor, and from there, transfer to a local elevator depending on the destination. Although installed, it is unknown which local elevator group the transit passenger from the shuttle elevator will use, and it is not possible to determine which group of elevators may arrive. This problem can be solved by providing a transit button for each destination floor and destination zone, but it cannot be effectively used because there is no means for determining whether or not the transit passenger has boarded a prepared local elevator. Besides, since there are multiple elevator groups, the distance from the shuttle elevator to the local elevator is long,
The travel time from the shuttle elevator to the arrival at the local elevator becomes long, and the individual difference in arrival time becomes large. For this reason, even if the local elevator arrives at the time when the person who can walk becomes arriving, if the transit passenger is a person who cannot walk, it is necessary to wait until the latter arrives. For this reason, the stop time of the local elevator becomes long, which leads to a decrease in efficiency. In the sky lobby, there are shops, restaurants,
Coffee shops and event venues are often set up. Therefore, in addition to transit passengers, there are also inflow passengers from the sky lobby. Therefore, even when waiting for the elevator for transit, inflow passengers from the sky lobby often board and leave as they are and are not available for transit passengers. If you keep waiting for transit passengers to arrive, the convenience of transit passengers from the Sky Lobby level will be significantly impaired.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to improve the overall efficiency of a transit user and a local elevator user.

The main purposes of preparing an elevator for transit passengers are the following two points.

(1) To reduce the number of button operations by the transit user to reduce the complexity of transit.

(2) The transit user is promptly boarded in the local elevator, and the number of people stopped at the sky lobby elevator platform is reduced.

In the conventional example, a transfer button is prepared on the shuttle elevator side, and when the transfer button is pressed, the number of button operations is reduced by registering the hall call for the local elevator transfer floor. In this way, even if you have to wait for transit due to some inflowing passengers from the transit floor, etc. where the transit passengers' arrival times are not constant, it is not possible to know when the transit user will board, Since the passengers cannot use it because they get on board, there is a problem that the effect of connecting control cannot be expected in such a case.

Therefore, a means for detecting the arrival of the user is provided at the entrance of the elevator hall, and when the user arrives, the hall call is automatically registered to reduce the number of times the user including the transit passenger pushes the button. It was done like this. Further, the waiting time can be reduced by the amount of time the user walks to the front of the elevator. In addition, if an immediate reservation system that notifies the assigned elevator when a hall call is registered is adopted, it may be guided to another elevator after moving to a certain elevator and pressing the hall call button. It is necessary to move, but in this method, you will be guided at the entrance,
Since it is possible to go directly in front of the service elevator, the service elevator can be easily found, the moving distance can be shortened, and the complexity of boarding can be reduced.

As for reducing the number of non-stop staff, a means for seeking non-stop staff in the hall is provided, and the number of non-stop staff is large.
When one car cannot provide the service, a plurality of cars are called.

[0011]

Operation: The user detection means installed at the landing of the local bank on the sky lobby floor detects that the user has arrived at the landing and creates a hall call. Since the destination from the Sky Lobby floor is usually either the upper side or the lower side, the hall call can be created when the user arrives at the platform. Next, the allocation control means allocates the optimum elevator to the generated hall call. Furthermore, the waiting person detection means detects the number of waiting people at the landing,
If one assigned car cannot be used, the group management controller assigns a plurality of cars to the hall call. In this way, the user can call in the elevator without pressing the hall call button, and the hall call can be generated at the arrival at the landing, so that the waiting time can be substantially shortened. .

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of the present invention. When any one of the hall call buttons 1a to 1n is pressed, the signal is sent to the hall call collection unit 31 in the group management control device 3 through the transmission line 2. Information about the car positions, the number of people in the car, car calls, etc. of the machine control devices 41 to 4n is sent to the machine information collection unit 32 in the group management control device 3 through the machine transmission line 21. The allocation unit 33 is the hall call collection unit 31.
When the hall call is detected, the elevator to service the hall call generated based on the information of the machine number information collecting unit 32 is determined, an allocation signal is sent to the machine control device through the machine transmission line 21, and the machine control devices 41 to 41 are connected. 4n runs a car to service the hall call.

When the line sensor 5 installed at the entrance of the elevator hall on the connecting floor detects the arrival of the user,
A detection signal is sent to the hall call collection unit 31 of the group management control device 3. The hall call collection unit 31 receives the detection signal as the hall call generation and determines the service elevator. The waiting passenger sensor 6 detects the waiting number at this time and sends it to the allocation unit 33 of the group management control device 3. Allocation unit 33
Determines whether the number of persons detected by the waiting person number detecting means 6 can be overcome only by the assigned service elevator, and if not, additional allocation is performed.

FIG. 2 is a flow chart of the present invention.
First, the hall call collection unit 31 detects a hall call (201). Next, it is checked whether or not there is an input to the line sensor (202), and if there is no input, the machine information collection unit 3
2 detects the car call (203), the allocator predicts the arrival time (204), and determines the service elevator suitable for the generated hall call (205). Next, a long wait process is performed (206), and then other processes are performed (207). When the line sensor 5 has an input and the passenger arrives at the hall on the transfer floor, this signal is sent to the hall call collection unit 31 in the group management control device 3 and registered as a hall call (208). Next, the output of the waiting passenger sensor 6 is detected (209), and the allocating unit 33 determines whether or not one vehicle can be overridden (209).
Returning to 3), if the passenger cannot get through, the elevator is additionally allocated and the process returns to (209) and (203).

In this way, the hall call is registered at the same time as the transit passenger arrives, and is automatically allocated if the passenger cannot get on the train, so that the number of stop personnel on the transit floor can be reduced without impairing the convenience of the transit passenger. Since it is possible to reduce the number of elevators and the elevator is not additionally stopped for transit passengers, it is possible to prevent the serviceability of other floors from being impaired.

FIG. 3 is an explanatory diagram of the present invention. (A) has shown the operation diagram of a shuttle elevator and a local elevator. (A) As shown on the right, when the transfer control is not performed, the waiting time of the connecting passenger on the sky lobby floor, which is the connecting floor, is long, but the waiting time on the other floors is good. If the local elevator is made to wait until the arrival of the shuttle elevator in order to reduce the convenience of the transit passengers and the number of staff on the sky lobby floor, which is the transit floor, the waiting time for the transit passengers will be reduced, but that of other local elevators will be reduced. Waiting time on the floor increases. Therefore, it can be seen that the waiting time increases if transfer control is performed so that the local elevator waits for the passengers connecting from the shuttle elevator. (B) is
It is an example of the moving distance of a transfer floor. Since most buildings requiring transit are large-scale buildings, it is expected that the number of local elevators will be 6 to 8. At this time, if four elevators are installed as in (b), the depth of the elevator hall will be about 11 m, and the travel distance from the shuttle elevator hall to the local elevator hall will be 10 to 20 m. Therefore, since the individual difference in travel time when walking is several seconds or more, we try to prevent the deterioration of service on other floors by waiting at the transit floor by arriving the elevator at the transit floor according to the arrival of transit passengers. However, due to the difference in arrival time, it is necessary to wait for several seconds or more at the transfer floor. This is because the number of local elevators that normally make transit connections is not limited to one, so if the shuttle elevator arrives and arrives at the local elevator at the earliest arrival time of the user, if the transit passenger is a weak person, the local elevator By the time they arrive at the landing, they arrive more than a few seconds later than those who walked, so the local elevator must wait for that time.

Furthermore, on the floor of the Sky Lobby, there are shops and restaurants,
Rest areas are often set up, and not only transit passengers but also inflow passengers from these sky lobbies will use the local elevator. Since passengers from the sky lobby will board the elevator reserved for transit passengers, if the elevator is not left to wait for transit passengers, the waiting time for inflowing passengers becomes long and frustration occurs. Also, even if you wait, if there are many inflowing customers from the sky lobby, there will be a problem that transit passengers will not be able to get on. Therefore, as shown in (d), a line sensor is installed at the entrance of the landing, a hall call is registered with the arrival of passengers, the waiting passenger sensor detects the number of waiting people, and if the passengers cannot get through, additional allocation is made. The convenience of connecting passengers will be improved without waiting for the local elevator in vain, and the number of passengers on the transfer floor will be reduced. Here, the example of the transfer from the shuttle elevator to the local elevator has been described, but the reverse case is also the same.

FIG. 4 shows an example in which the line sensor and the waiting passenger sensor are used together. The waiting passenger sensor can be used as a substitute for the line sensor for detecting the arrival of the user at the landing by detecting the movement of the person as well as the static waiting person detection. Therefore, in this example, the output of the waiting passenger sensor 6 is sent to the allocating unit 33 to replace the line sensor. According to this embodiment,
Since it can be realized without using a line sensor, an inexpensive system can be provided.

FIG. 5 is a flow chart when the line sensor and the waiting passenger sensor are used in common. After detecting the hall call (201), the allocation unit 33 detects the output of the waiting customer sensor (202-1). The passenger movement is checked to see if there is a new arrival passenger in the hall, which is the elevator hall (202-2), and if there is no arrival passenger (2)
03) and subsequent steps are the same as in FIG. If there is an arriving customer, it is registered as a hall call (209), and it is then checked whether or not the vehicle can be overridden by one (211).

FIG. 6 shows an embodiment in which an automatic division express is carried out at the time of congestion. When it is detected by the output of a clock or a waiting sensor 6 not shown here that the traffic volume cannot be judged by normal control, the allocation unit 33 decides to carry out the division express and instructs the display control unit 34 to perform the division express. The display control unit 34 displays a signal to the effect that it will be performed, and displays the service floor of each elevator on the display device 7. Here, the case where one display device is installed in the center of the hall has been described, but the display device 7 may be installed for each elevator or both.

FIG. 7 is a flow chart in the case of carrying out an automatic division express during congestion. Hall call assignment (205)
Up to this is the same as in FIG. After that, it is checked whether it is in a congestion time zone or whether the waiting sensor has detected congestion that cannot be serviced by additional allocation (213). If not detected, the long waiting process is continued as in FIG. Perform (206). If it is in a crowded time zone, a split express operation is started (214), and the destination floor of each elevator is displayed on the display device 7 (215). After the additional allocation (212), the congestion time zone determination (213), the division express (214), and the destination floor display (215) are similarly performed. Other than this is the same as FIG.

FIG. 8 shows an embodiment in which the number of people waiting for the arrival of the elevator is predicted by learning. The learning unit 35 in the group management control device 3 is a transfer floor from the group management control devices of other banks such as the hall call collecting unit 31, the machine number information collecting unit 32, the information of the waiting sensor 6 and the shuttle elevator to which the user transfers. The arrival number, the number of passengers in the arriving car, and the like are received via the communication unit 36, and these are learned for each time zone and each occurrence event. The allocation unit 33
Service elevators are assigned using the learning result with the highest accuracy. For example, if the learning result that most of the users arriving by shuttle elevator at a certain time zone use a specific local elevator is obtained, the allocator determines the output of the waiting passenger sensor and the expected number of arrivals of the learning result, If it is predicted that the passengers will not be able to board the train, considering the arrival status of the local elevator at the transit floor, additional allocation will be made in advance so that the elevator will arrive after the arrival time of the transit passenger. According to the present embodiment, an elevator for additional allocation can be prepared when congestion is predicted in advance, which further improves the convenience for transit passengers. In addition, since users other than the transfer floor are additionally allocated in advance and the service elevator is determined in anticipation of the congestion of the elevator, it is possible to provide a good service compared to the traffic volume.

Here, an example in which the allocation is performed by using the information of other group management is also explained, but if the accuracy of the learning result can be increased, the information of the waiting passenger sensor and the machine information collecting unit can bring a certain effect. To be

(201-1), the information of the group management control device 3b of another bank is received via the communication unit 36 (2-1).
01-2), when additionally allocating an elevator (211), when allocating a hall call (205), the allocation is performed in consideration of these information, and after other processing (207), a hall call or other learning is performed. It is similar to FIG. 2 except that it is performed.

[0025]

According to the present invention, if an immediate reservation system for notifying an assigned elevator is adopted when a hall call is registered, the elevator may be guided to another elevator after moving to a certain elevator. Therefore, it is necessary to move again, but in this method, since it is guided at the entrance, it is possible to go directly to the service elevator, so it is easy to find the service elevator, the travel distance can be shortened, and the trouble of boarding is reduced. It can be reduced.
