Abstract

PURPOSE:To prevent a passenger from missing a cage by closing the door after confirming that the passenger has boarded the cage, when the hall call of a floor is registering that the cage is waiting for the door to close on this floor and the cage waiting for door to close responds. CONSTITUTION:When the hall button of a floor is operated to register a call during a cage is waiting for door close on this floor, this signal is inputted to a group-management control unit. Then, the group-management control unit selects and assigns the most suitable cage to respond to the registered call, and consequently, the assignment is outputted to the waiting cage. The assigned cage opens a door, lights an indicator to inform the passenger that it is the responding cage, and urges the passengers to board the cage. When a unit control unit confirms that the passenger has boarded the cage by the signal from a getting on/off detector 34, door close instruction is outputted to a door control unit to close the door and start the cage. Thus, the passenger can be prevented from missing the cage.

Description

[Detailed description of the invention] [Purpose of the invention] Related to door opening/closing control method.

(Prior art) A control system called group control control selects the most suitable elevator to handle the hall call when a hall call occurs, immediately assigns the elevator to respond to the hall call, and also assigns the elevator that responds to the hall call immediately. Elevators may not be allowed to respond to calls at the platform, or when traffic demand increases, such as during the morning rush hours, evening work hours, and lunch hours, or when traffic decreases, such as at night or on holidays. , which controls elevators to ensure efficient operation by switching to preset operating modes according to traffic changes unique to the building.

In addition, in order to move all the cars efficiently, when there is no demand, they are evenly distributed and placed on standby with the door closed.

When a hall call occurs, the most suitable elevator to handle the hall call is selected and assigned, so if a hall call for the same floor as the one you are waiting for occurs, the car on that floor is immediately You will have to respond.

(Problem to be Solved by the Invention) However, it is not always the case that there are passengers near the car waiting with the door closed and the hall call button operated. Therefore, in the case of a building with a large boarding area where multiple elevators are installed side by side and group control is performed, if the car that responds is far from where passengers are waiting, it is possible to miss the car. There is. Conventionally, as a method to solve such problems, it has been considered to prevent the car door from being opened for a certain period of time, or to set a longer time than usual for the car door to be open. However, since the time it takes to board the car varies depending on where the hall call is registered, it is impossible to set or predict the time. Furthermore, the time it takes to board the car varies depending on whether the registered person is young or elderly.

In the present invention, when a car is waiting with its door closed, a landing call for that floor is registered, and when the car waiting to close its door responds immediately, the passenger operates the hall call at a position away from the car that answered. By preventing people from missing the car when the car is operated by an elderly person or when the person operating the car is elderly,
The aim is to provide safe and easy-to-ride elevators and improve service.

[Structure of the invention]

(Means for Solving the Problem) In order to achieve the above object, in the present invention, a plurality of elevators serving a plurality of floors are installed in parallel,
An elevator control device that performs group management control that instantly selects and allocates the most suitable elevator to respond to a common hall call that occurs, and a single control device that controls each elevator individually.

A load detector that detects the load inside the elevator car and a load detection signal from this load inspection device are input at fixed time intervals and processed, and as a result, the load increases by more than a predetermined position value before and after the time, or A boarding/alighting detector that outputs a boarding inspection signal or alighting signal when a passenger boarding or alighting in the car, provided that the number of passengers boarding or alighting has decreased, a boarding/alighting detector that outputs a boarding inspection signal or alighting signal when a passenger enters or exits the car, a hall call button that registers a hall call at the landing on each floor, and a door The car has a door control device that controls opening and closing, and when the car is waiting with the door closed, registers a landing call for that floor, and when the car waiting with the door closed responds to the landing call that has occurred, To provide an elevator control device characterized in that the door is closed after confirming that a passenger has boarded the car using a boarding/alighting detector.

(Function) In the system configured as described above, first, when a car is waiting with its door closed and a landing button on that floor is operated and a call is registered, the signal is input to the group management control device.

The group management control device selects and allocates the car most suitable for responding to the registered call, and as a result, the allocation is output to the waiting car.

The assigned car opens its door and lights up the 1 indicator light to notify passengers that it is a responsive car and to encourage them to board the car.

When the single controller confirms that a passenger has boarded the car based on a signal from the boarding/alighting detector, it outputs a door close command to the door controller to close the door and depart. Therefore, passengers can be prevented from missing the train.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In FIG. 1, 1 is a hall call control device, 3A-
3C is an individual elevator car control device that controls the movement of the car of each elevator car (single unit). Here, each car is distinguished by adding suffixes A to C.

Reference numeral 4 denotes a group management control device which allocates landing calls to each car based on the information on one landing call and each car and controls the operation according to traffic demand. In addition, although multiple parallel signal lines may be used to connect these signal lines, in Figure 1, only one signal line is used.
Shown as a book signal line.

FIG. 2 is a block diagram of the hall, with hall lanterns 26A to 26C and hall call buttons 27A to 27C.

When the hall call buttons 27A to 27G are pressed, the hall call is registered by the general hall call control device 1, and the hall condition information table in the group management control device 4 (stored in a part of the memory, hereinafter referred to as rHcTJ)5
The bit Ba of the index data corresponding to each hall call is set.

(See Figure 3) Arithmetic device (including input/output device) 7 in the group management control device 4
searches for this, in this case selects the optimum machine from among the three machines A to C, and gives an output to the quasi-call registration circuits 8A to 8C. At this time, since a lighting command is simultaneously issued to the lantern control circuits 9A to 9C, the hall lanterns 26A to 26C, that is, the forecast lights are lit.

At the same time, the target hall call index bit Bb and the assignment bit Be corresponding to the car number are set for the assignment of the HCT5. (See FIG. 3) When a passenger gets into the car, the boarding and alighting detectors 22A to 22C detect the passenger getting into the car, and this is stored in rCCTJ for each car as a car status signal.

FIG. 6 is a block diagram showing an example of the configuration of an elevator boarding/alighting detection device used in the present invention.

In the figure, 31 is a load detector that detects the load inside the elevator 32 and converts this load value into an electric signal corresponding to it and outputs it, and 33 detects that the door 32a of the elevator car is not in a fully closed state. A contact that closes by
34 inputs the load detection signal from the load detector 31 at fixed time intervals (for example, at intervals of 10 cm), and the door 32a of the elevator car is fully closed by the contact output signal from the contact 33 indicating the open/closed state of the door. Calculation processing is performed on the condition that there is no condition, and as a result, it is detected that the load value has increased or decreased by more than a predetermined value (for example, 30 kg) before and after the time, and the passenger is not allowed to board or exit the car. This is a boarding/alighting detector that outputs a boarding detection signal or alighting detection signal 34a if there is a boarding/alighting detection signal 34a, and constitutes a boarding/alighting detection device 35. Here, as the load detector 31, for example, a near-home machine, a load cell, etc. can be used.

In the above diagram, first, while the unit A in Figure 2 is waiting with the door closed,
A passenger waiting in front of Car C operates the hall call 27b, and the call is registered by the first hall call control device shown in FIG. 1, and the corresponding bit 5rHCTJ in the first group management control device 4 is set. These pieces of information are input to the 7 arithmetic units via input devices. And in the 7 arithmetic unit, 21rC
The status of each car (position, direction, arrival time) obtained from CTJ.

Judging from the arrival distance, number of assigned cars, etc., it is determined that car A is the best to respond to this call, and an allocation command is output to car A via the output device.
The assignment bit and call bit of the corresponding floor of rHcTJ are set.

On the other hand, in car No. A, the assignment command from the group management control device is input through the 8A quasi-car call circuit, and is input into the calculation device along with the car position, door, and other car status. the result,
When it is determined that a car is currently waiting on the assigned floor, it immediately responds and outputs a door opening command to the 24A door control device. At the same time, an assignment command is also input from the 9A lantern control circuit to light up the 26A lantern.

Next, the operation within the 12A arithmetic unit will be explained using the flowchart shown in FIG.

First, when it is detected that your car has been assigned (Fig. 4, 4a), it is determined from the direction, position, door condition, etc. that the car is waiting with the door closed, and the waiting assignment flag is set. set. (4a to 4c) After the door is completely opened, it is determined whether the assignment is on standby, and if not, the process is skipped and normal door opening/closing control is performed (Fig. 5, 5a to sb). If the assignment is on standby, the process proceeds to step 5c, where the unloading device 34 inputs the load detection signal from the load detector 31 at regular time intervals (for example, 10+m5ec intervals), and
A contact output signal from a contact 33 indicating the open/closed state of the door 32a is inputted, and entry/exit is detected by comparing the load signals before and after opening the door 32a with the minimum load. That is, in the case of passenger detection, first, as shown in FIG. 7, the open/closed state of the door 2a is detected in step S1, and if the door 2a is fully closed, the minimum load value is reset to the current load value in step S2. , when the car runs and the door 2a is opened, the minimum load value and the current load value are compared in step S3, and if the result is that the load value is smaller than the minimum load value, step S4 is performed.
Set and update the minimum load value to the current load value.

Moreover, if the current load value is larger than the minimum load value, the minimum load value is estimated from the current load value and the riding load value is set in step S5. Then, in step S6, the vehicle load value is compared with a predetermined load value (for example, 30 kg), and if the vehicle load value is larger than the predetermined load value, it is determined that at least one passenger is in the car. Then, in step S7, the occupancy detection signal 34a is outputted to the outside.

In process 5c of FIG. 5, the door is kept closed until this boarding detection signal is received. When the load is detected, the process proceeds to step 5d, where a door closing command is output to the door control device (248 in FIG. 1), and the standby assignment flag is cleared.

As explained above, when a car is waiting with the door closed, a landing call occurs on that floor, and that call is caused by the operation of a landing call button located far away from the waiting car. You can also board the car without missing the train.

Note that the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with modifications without changing the gist.1 For example, the timing for clearing the flag may be changed to when the door close command is output. If we change the system from ``open'' to ``close the door completely'' and allow the door to be opened while the flag is on, even more detailed service can be provided.

〔Effect of the invention〕

As explained above, in the present invention, when a car is waiting with the door closed, a landing call for that floor is registered, and when the car waiting with the door closed immediately responds, the passenger leaves the car that answered. If you operate the hall call at your current location, or if the person who operated it is an elderly person, you may miss your car. By preventing this, it is possible to provide elevators that are safe and easy to ride, and improve services.
