Abstract

PURPOSE:To perform elevator group operation control efficiently by outputting an assignment signal of floor call to an elevator other than an assigned one only in case a passenger on a floor makes a call when the assigned elevator is being closed and the passenger fails to enter the assigned elevator. CONSTITUTION:A floor call is inputted at a call button set 3 through a floor call output control unit 4 when a door open command is off, and latching is made with a register request flag at the down edge of gate signal. Then, existence or absence of the register request flag is detected at the down edge of a floor call cancel signal. If a register request flag is set up, a floor call special mask is kept turned on until this routine is started next time. At the moment when the assigned elevator has been closed, this floor call special mask becomes equivalent to the condition where a floor call has been registered, the floor call lamp grows again, and an assignment command is given by a floor call assignment control task to an elevator other than the assigned elevator which is starting.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator group management control device that operates a plurality of elevators for a plurality of floors.

(Prior art) In recent years, when multiple elevators are installed in parallel, in order to improve the operating efficiency of the elevators and improve the service to elevator users, it has become necessary to increase the number of elevators that respond to hall calls on each floor. Efforts have been made to allocate information rationally and quickly using small computers such as microcomputers. That is, when a hall call occurs, group management control is performed to select and assign the most suitable elevator to service the hall call, and to prevent other elevators from responding to the hall call.

Under these circumstances, in conventional elevator group management control systems, hall lanterns are installed for each floor, each car, and each direction, and the lanterns are turned on at the timing when a hall call is assigned, and a chime 1 hit is used to notify reservations. Also, lanterns will be lit and chime 2 will be lit a certain time before arrival.
When the dot is set, the lighting of the hall call button lamp disappears, and from then on, the train responds to the hall call, arrives at the floor where the hall call occurred, stops, opens the door, and begins to close the door after passengers have boarded and alighted. , the lantern flashes until the door is almost completely closed, and at the same time a process is performed to invalidate the landing call registration for the current floor.

(Problems to be Solved by the Invention) However, such conventional elevator group management control devices have the following problems.

If the assigned car responds and stops at the floor where the hall call occurred, and a new passenger is waiting at the hall while the door is open, the lantern will be turned on without pressing the hall call button if the door is open. You can judge the responding car from the flashing status and board the corresponding car. However, for passengers waiting in the landing after the start of the door-closing operation, it can be determined that the assigned car is on the relevant floor based on the blinking status of the lantern, so they request the door to be re-opened by pressing the hall call button.

However, for boat fishing, as mentioned above, when the assigned car approaches the end of closing the door, the landing call registration becomes invalid, so the door of the corresponding car does not reopen, and furthermore, the landing call button operation becomes invalid. Passengers waiting at the landing must operate the hall call button again after the door of the relevant car has been closed and the hall call registration becomes valid, and for these passengers waiting at the hall, opening the door by pressing the button the first time is ignored. However, there is a problem in that the user has to operate the button again, resulting in double dissatisfaction.

In addition, there are also known elevators with specifications that enable the door opening function by a hall call while the assigned elevator is opening the door. Because it is undesirable for elevators to stop for long periods of time, unlike general one-car elevators, the range in which the door can be opened is limited by time or the number of times the door can be opened again. The hall call button that is pressed later has the same problem as when the door opening function is disabled.

Furthermore, it is possible to enable the landing call registration after the assigned car starts opening the door and assigning it to another car, but if the passenger in the car notices the passenger waiting at the landing while the door is closing,
If the door of the corresponding car is reopened by operating the door open button on the in-car operation panel, only the landing call registration will remain, resulting in wasted operation in terms of group management control, which is not desirable in terms of group management control efficiency. There were no problems.

The present invention was made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an elevator group management control device that is easy to use for passengers waiting in the hall when the assigned car has completed its response. shall be.

[Structure of the Invention (Means for Solving the Problem) This invention is an elevator system in which a plurality of elevators are put into service for a plurality of floors, and an elevator of the optimum number is selected and assigned to a common hall call. In the group management control device, means for detecting a landing call registration operation after the assigned car responds and starts door closing operation, means for detecting a door opening operation of the assigned car again, and the assigned car responds;
and means for re-registering the hall call without re-opening the door of the assigned car when the hall call registration operation after the door closing operation is started is detected.

(Function) The elevator group management control device of the present invention detects the hall call registration operation after the assigned car responds and starts the door closing operation, and after the registration (re-opening force) t'l + is set near the time when the assigned car has completed its door closing.And, with this condition satisfied, the door closes 11J ('IE It is determined that the passengers waiting at the landing were unable to get on the assigned car 1, A new landing is registered, an elevator other than the assigned one is newly selected, and the notification is made to the landing.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is a group management control section, and this group management control section 1 includes individual control sections 2-1 to 2-N for controlling each unit elevator, and a learning system. It is connected to the control section 1-1 via a high-speed transmission line 6, which is a first transmission control means.

The group management control section 1, the learning control section 1-1, and the individual control sections 2-1 to 2-N are constituted by one or more small computers such as microcomputers, and operate under the control of software.

3 is a hall call button provided on each floor, and 4 is a hall caller output control unit that inputs and outputs hall calls. The group management control unit 1, the learning control unit 1-1, the individual control units 2-1 to 2-N, and each hall call input/output control unit 4 are as follows:
They are connected via a low-speed transmission line 7, which is a second transmission control means.

The high-speed transmission line 6 is a transmission line between the individual control units 2-1 to 2-N and the group management control unit 1 and the learning control unit 1-1, that is, mainly between the control machines in the machine room. It is a control system,
Connected by a fast and highly intelligent network. Then, control information necessary for group management control is transmitted to the group management control section 1, the learning control section 1-1, and each of the individual control sections 2-1 to 2-.
Data is exchanged between H at high speed.

The low-speed transmission line 7 is a control system that mainly transmits information via the hoistway, such as the hall call button 3 of each landing and the monitoring panel 5 of the monitoring room, and is slower than the high-speed transmission line 6. , is constructed of an optical fiber cable or the like for long distance, and is connected to the group management control section 1, learning control section 1-1, and individual control sections 2-1 to 2N to exchange data.

When the group management control unit 1 is normal, the hall call button 3 is controlled by the group management control unit 1 via the low-speed transmission line 7, and when the hall call button 3 is pressed, the hall call gate is closed and the registration lamp is turned on. At the same time, the information of the unit control units 21 to 2-N sent via the high-speed transmission line 6 at h is determined to the optimum unit number to 7, and Issue control commands to the applicable items. Then, the unit control unit that receives the control command performs unit control using this control command as hall call information.

FIG. 2 shows a group management control unit 1 and a single control unit 2-1 in an embodiment of an elevator ffT management and control device of the present invention.
~2-H shows an example of the software system,
This software system is configured to manage a single control function task 9, a group management control main function task 10, a group management control subfunction task 11, and a transmission control task 12 using the real-time O58, which is an operating system. Each of the tasks 9 to 12 is activated or held by the scheduler.

Single control function task 9 among these tasks 9 to 12
is a task for operating the single control units 2-1 to 2-N, and is given a high priority.

The group management control main function task 10 is the central function of the group management control section 1, and receives information data for each machine from the group management control subfunction task 11 distributed to each individual control section 2-1 to 2-H. The optimal machine is determined by collecting and performing comparison calculations, and a control command is issued to the relevant machine.
Controls hall call registration.

The group management control sub-function task 11 is a function of processing information for each machine of the group management control section 1, and processes the information under the control of the group management control main function task 10. That is, the computer having the group management control main function task 10 manages the start and termination of tasks via the high-speed transmission line 6, and is configured to manage the start and termination of tasks by the computer having the group management control main function task 10, and to perform control according to commands from the group management control main function task 10, which is the master. - Distributed processing is performed for each machine, and data is transferred to the group management control main function task 10 upon completion of processing.

The transmission control task 12 controls the transmission and reception of data on the high-speed transmission line 6 and the activation and termination of the group management control subfunction task 1.

FIG. 3 is a block diagram showing the system configuration of the high-speed transmission line 6 shown in FIG.
For example, a data link controller 14 and a media access controller 15 configured with hardware are used as parts for controlling the data link layer of the LAN network model layer proposed by I5O (International Organization for Standardization). The configuration is such that data transmission is performed in a highly intelligent manner, and the ratio of transmission control software managed by the microprocessor 13 is reduced for high-speed transmission control. For example, as the data link controller 14, which is a controller for realizing the above-mentioned highly intelligent transmission control, the LSI 182586 manufactured by Intel Corporation (IN Okisha) has been put into practical use, and as the media access controller 15, the LSI 182501 also manufactured by Intel Corporation has been put into practical use. However, by using these, high-speed transmission functions such as IOM bits/second can be performed relatively easily with a reduced support ratio of the microprocessor 13.

In addition, in Fig. 3, 16 is the system bus, and 1
7 is a control line, and 18 is a serial transmission system.

FIG. 4 shows the control function section in the group management control main function task 10 based on the present invention. As shown in the figure, this task 10 is composed of a hall call assignment control task 19 that determines the assigned car number when a hall call occurs, and a hall call control task 20 that executes personnel output control for hall calls.

Next, the operation of the elevator group management control device having the above configuration will be explained.

When a hall call is generated by operating the hall call button 3,
The information is sent to the low-speed transmission line 7 via the hall caller output control section 4. And this information is group management control section]
is taken in by the group management control main function task 10, and this landing call assignment control task 19 determines the optimum car in synchronization with the group management control subfunction task 11 of each individual control unit 2-1 to 2-H. A hall call is assigned by issuing a control command to the corresponding car via the high-speed transmission line 6.

FIG. 5 shows a time chart of main signals when the elevator group management control device of the present invention responds to a hall call, and FIG. 6 is a flowchart showing the operation of the hall call control task 20. shows a flowchart showing the hall call special mask generation control operation used in the hall call control task 20.

First, the operation of the hall call control system will be explained in the quillyard shown in FIG. When the assigned car responds to the corresponding landing, after starting deceleration at timing t1, the hall call clearing signal is output on, the hall call lamp signal is cleared, and the hall lantern starts blinking.

Timing t when the allocated car arrives and stops at d2
At step 2, the door opening command is turned on and the door begins to open in synchronization with this. Passengers waiting in the hall who have been generated while the door opening command signal is on can board the assigned car because the door is fully open and the hall lantern is flickering.

However, after the start of the door closing operation, that is, at timing t3 when the door opening command is once turned on and then turned off, the door starts the closing operation.

The following will be explained using the flowchart of FIG. 6. When the door opening command is in the OFF state (Δt in FIG. 5), gate input is performed to the corresponding hall call gate 3 via the hall call output control unit 4, and the gate signal is output. The registration request flag is latched at the down edge, that is, when the passenger waiting in the hall releases the hall call button 3 (steps S1 to S
7).

In the example shown in FIG. 5, the registration request flag is set at the down edge of the hall call gate signal pulse, and Δ is used for detecting intermediate calls.

Then, the presence or absence of the registration request flag is detected at the down edge of the hall call cancellation signal, that is, near the completion of closing the door of the assigned car (steps 88 to 510).

The fact that the registration request flag is set corresponds to a case in which the assigned machine detected a hall call after the door closed, but did not open the door again. In this case, the hall call special mask It remains on until this routine is started (step 511).

As shown in the hall call control flowchart shown in FIG. 7, this hall call special mask is ORed with the hall call gate (steps S21 to 52B), so the moment t4 when the door of the assigned car is closed, The state is the same as when a hall call was registered in , the hall call lamp lights up again, and the assignment command is executed by the hall call assignment control task to a new aircraft other than the assigned aircraft that started departure.
The hall lantern of the elevator of the corresponding machine lights up.

Although this embodiment describes an example in which the door does not open again, re-opening is enabled in elevators with specifications that allow the door to be re-opened by the door-open button on the in-car operation panel or by a hall call. During this time, the registration request flag is set because the door-opening command signal is turned on again by the door-opening operation, and the hall call is not re-registered. In other words, for hall call gate detection detected after the door closing operation has started,
Re-registration is performed only when the door of the assigned car is closed and the door is not opened again after the hall call gate is detected.

In this way, in the embodiment of the present invention, a call is re-registered for a passenger waiting in the hall who has occurred after the assigned car started closing the door, only when the door does not open again. Since the assignment is output to other aircraft, it is possible to improve usability for passengers waiting at the platform and prevent a decline in group management control operation efficiency.

In addition, although the above-mentioned embodiment mainly explained specifications in which reopening by a hall call is disabled, this invention is not limited to the above-mentioned embodiment, and even in cases where reopening by a hall call is effective. , it can be handled in the same way when it exceeds the effective range.

Further, in the above embodiment, the hall call registration lamp does not light up when the gate is pressed, but the same can be applied to the case where the hall call button lamp is turned on synchronously.

[Effect of the Invention] As described above, according to the present invention, even if a passenger is waiting at the landing while the assigned car is on the corresponding floor and the door is closing, if the passenger waiting at the landing is unable to board the allocated car, Since only the hall calls are assigned to elevators of other elevators and output, there is no need for passengers waiting at the hall to press the hall call button again, and from the standpoint of group management control efficiency, wasted operation due to unnecessary hall call registration is avoided. This enables efficient group management control and improved services for users.
