BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a group management control system for elevators.

0003

[Background Art] In recent years, when multiple elevators are installed in parallel on multiple floors, in order to improve the operating efficiency of the elevators and improve the service to elevator users, it is necessary to respond to hall calls for each floor. Group management control is adopted in which elevators are allocated and reserved in a rational and prompt manner using a microcomputer or the like.

That is, when a hall call occurs, the most suitable elevator to service the hall call is selected and assigned, and other elevators are controlled not to respond to the hall call.

[0005] Recently, in the above-mentioned group management control devices, devices having a learning function are used to measure the elevator car call registration data that responded to each hall call in real time, or to measure the boarding and alighting load data, etc. As a result, it has become possible to understand the traffic volume between floors and the average time between arrivals at each floor landing.

[0006] Then, based on these measurement data, the measurement data is processed for each time period to understand the specific demand of that building and determine the optimal number of cars when a hall call occurs, or when arriving at work or during lunch. It is applied to group management control such as setting clock-out times, setting distributed standby zones during off-peak hours, and setting the number of idle machines to save energy.

In a group control elevator with such a configuration, hall lanterns are installed on each floor and in each direction of each car, and generally the lanterns are turned on and the chime is turned on once a hall call is assigned. We will notify you of your reservation and at a certain time before the arrival of the elevator car.
Controls the blinking of the lantern and the chime to notify the arrival of two points.

[0008]

[Problems to be Solved by the Invention] By the way, in group-controlled elevators based on the assignment system, passengers waiting at the boarding point wait in front of the elevator for which reservation notification has been made, and the lantern flashes and the chime hits two points a certain time before arrival. Knowing the timing of their arrival, they are preparing to board the elevator. However, if the waiting time for the platform call becomes long, the reservation number is reviewed due to late arrival, or the assignment is changed to another aircraft due to a malfunction of the reserved aircraft, etc., the passenger waiting in front of the reserved aircraft may If you are not aware of the change and are delayed in moving to the rescheduled bus, you may end up missing the boarding of the rescheduled bus.

[0009] In particular, when the reserved aircraft number is revised due to a prolonged waiting time at the boarding point, the changed aircraft number generally arrives at the relevant floor immediately, so the above-mentioned problem may occur. The sex is great.

[0010] In addition, since group management elevators manage a plurality of elevators such as 6 or 8, there are cases where the reserved number after the change is located opposite the previously reserved number, or the reserved number after the change is located a little far away. In some cases, such as when customers are located far away from each other, even if the waiting customers notice the change immediately, they are often unable to respond to the change immediately.

[0011] Since the purpose of the group control elevator is to maintain a reservation system and efficiently manage operation, the function of reopening the door by a hall call is disabled. For this reason, even if a passenger waiting at the landing notices that the reserved car number has changed and presses a nearby hall call button, the original elevator door where the passenger was waiting will not reopen, so there is a high possibility that recovery will not be possible.

[0012] As a countermeasure to this problem, there is a method of always enabling the door reopening function by a landing call, but if this function is enabled indefinitely, it will be contrary to the purpose of group management and will lead to a decline in group management performance. become.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention aims at group management control of an elevator that maintains group management performance and improves usability for passengers waiting in a hall.

[Configuration of the invention]

[0015]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a system in which, in a group management-controlled elevator, when there is a later change in the number assigned to the hall call, door control is performed by the hall call of the floor concerned. A means for temporarily enabling the open function is provided and configured.

[0016]

[Operation] The occurrence of reservation changes is monitored for each hall call, and the hall call in the corresponding direction of the floor where the change occurred is treated as a hall call for a specific floor, and when the hall call button is detected again, the corresponding elevator The system outputs a door-opening command to prevent passengers waiting at the boarding point from missing their boarding.

[0017]

Embodiments The present invention will be explained based on embodiments shown in FIGS. 1 to 6.

As shown in the block diagram of FIG. 1, a group management control unit 1 selects and allocates the most suitable elevator for a received hall call from a plurality of elevators operating on multiple floors, and controls the operation of each unit elevator. Single control unit 2-1~2
-n is connected by a high-speed transmission line 3, which is a first transmission control means. Group management control section 1 and single control section 2-1 to 2-2
-n is configured and operated by a plurality of microcomputers.

The hall call button 4 provided on each floor and the hall call input/output control section 5 that controls the input/output of the hall call signal are connected to the group management control section 1 and the single unit via the low-speed transmission line 6 of the second transmission control means. Connected to control units 2-1 to 2-n.

The high-speed transmission line 3 is a high-speed, highly intelligent network that connects the group management control section 1 and the individual control sections 2-1 to 2-n, that is, mainly between the control computers in the machine room. This is a control system, and control information necessary for group management control is exchanged at high speed between the group management control section 1 and each of the individual control sections 2-1 to 2-n.

[0021] The low-speed transmission line 6 is connected to the hall call button 4 of each hall;
It is a control system that transmits information sent mainly through the hoistway, such as the monitoring panel 7 in the monitoring room. It is connected to the group management control section 1 and the individual control sections 2-1 to 2-n, and sends and receives data.

Next, FIG. 2 shows the group management control unit 1 according to the present invention.
FIG. 2 is a block diagram showing the configuration of a software system of single control units 2-1 to 2-n.

In the software system, an operating system, ie, an OS 12, manages a single control function task 8, a group management control main function task 9, a group management control subfunction task 10, and a transmission control task 11, and a scheduler within the OS 12 manages each task. is activated or held.

The unit control function task 8 includes each unit control unit 2-
This is a task for operating 1 to 2-n, and the priority is set high.

The group management control main function task 9 is the central function of the group management control unit 1, and is the main function of the group management control unit 1.
Collect information data for each machine from the group management control subfunction task 10 distributed in
It issues a control command to the car concerned, and also performs monitoring control and control of the hall call button 3 after the hall call allocation time has passed. As mentioned above, the group management control main function task 9 performs the landing assignment control task 13, which determines the assigned car when a hall call occurs, and monitors the system status of the assigned car after the hall call has passed, and It consists of a hall call monitoring task 14 that detects open function permission and executes processing of the reopen function.

The group management control sub-function task 10 is a function of processing information for each machine of the group management control section 1 under the control of the group management control main function task 9. That is, a computer with a group management control main function manages the startup and termination of tasks via the high-speed transmission line 3, performs distributed processing on a unit-by-machine basis according to instructions from the master main function station, and sends the tasks to the main function station. The configuration is such that data is transferred when processing is completed.

The transmission control task 11 sends and receives data on the high-speed transmission line 3, starts the group management control subfunction task 10,
Controls termination.

The system of the high-speed transmission line 3 is as shown in the block diagram of FIG. That is, transmission control is configured using a microprocessor 15, but for example, in a LAN network model layer proposed by ISO (International Organization for Standardization), a data link controller 16 and a data link controller configured with hardware are used as a control part of a data ring layer. Using the media access controller 17, the configuration is such that data transmission can be executed in a highly intelligent manner.

This reduces the ratio of transmission control software managed by the microprocessor 15 to high-speed transmission control.

As the highly intelligent transmission control controller, for example, the data link controller 16 is an LSI i82586 (product name) manufactured by Intel Corporation, and the media access controller 17 is i82501 (product name) also manufactured by Intel Corporation. Because
With this specification, the high-speed transmission function of 10 Mbit/s can be achieved with a reduced support ratio of the microprocessor 15.
It can be configured relatively easily. In the diagram, the system bus 18
, a control line 19 and a serial transmission system 20.

The operation of the embodiment with the above configuration will be explained.

By operating the hall call button 4, the hall call gate is closed and the registration lamp is set, and information on the occurrence of a hall call is sent from the hall call input/output control unit 5 to the low-speed transmission line 6. The hall call information is taken into the group management control main function task 9 of the group management control section 1, and the hall call is registered. The hall call assignment control task 13 of the group management control main function task 9 determines the optimal car number in synchronization with the group management control subfunction task 10 of each individual control unit 21 to 2n, and sends the car to the relevant car via the high-speed transmission line 3. Issues control commands and allocates hall calls. In order to monitor the hall calls for which the allocation has been carried out, the group management control unit 1 receives information on each elevator from each individual control unit 2-1 to 2-n online via the high-speed transmission line 3, and performs a hall call monitoring function. Task 14 performs system status monitoring.

As shown in the flowchart of the embodiment shown in FIG. 5, the door opening permission condition is detected in the hall call monitoring control task 14 of the group management control unit 1, and the reservation change is performed for each car at the timing when the car stops. If a reservation change occurs, and the reserved aircraft is in the open state, if a call occurs in the target direction of the hall call, permission is given to open the door by the hall call. Set flag.

Next, FIG. 6 shows the execution of the door re-opening function. According to the above-mentioned hall call reopening permission graph set by detecting the hall call reopening conditions, reopening is permitted or Controls the decision to disallow permission.

In the hall call erased state, when the hall call reopening permission flag is on, the hall call gate signal is turned on, that is, it is detected that the hall call button is pressed, and the door is opened for the assigned car. Output the command. If there is a delay in determining the number of passengers waiting on the platform due to the above, recovery is possible.

[0036] As described above, when a reservation change occurs in the hall call assignment and the assigned car number is changed, the door re-open function by the corresponding hall call button becomes effective, so that there is some difference between the changed car numbers. Even if there is a distance of Furthermore, since the hall door opening function is limited depending on the conditions, the group management control function of the elevators will not be degraded.

[0037]

[Effects of the Invention] According to the present invention, even if a reservation is changed after a call is assigned in a group-controlled elevator, waiting passengers will not miss boarding, and the usability of the elevator can be improved. By temporarily enabling the door-opening function based on a landing call, it is possible to minimize the negative impact on the performance of the group management function.
