Abstract

PURPOSE:To make waiting passengers in an elevator hall get into a cage smoothly by guiding the passengers in the cage to the back of the cage almost full. CONSTITUTION:Receiving each command of a hall call input-output control part 5 and a group control part 10, a simplex control part 1 controls any motion of a cage 2. A motor control part 6 transmits a traveling state of a cage 2 and a load state of this cage 2 to the simple control part 1, through which it detects a fullness state. On the other hand, a cage inside information 3 is secured from the cage 2 too, whereby a message is outputted through a voice or display function from a data input unit 9 so as to make hall waiting passengers easy to board the cage owing to the cage inside information. For example, such an announcement that 'crowd all of you little yet closer at the back of the cage please' and so on, thus passengers in the cage 2 are put themselves close together, making them into ridable environment for passengers in the hall. With this constitution, these waiting passengers in the hall are boardable on the cage in a smooth way.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an elevator control device.

(Prior Art) Generally, an elevator control device is composed of a single control section and a motor control section. The car load status is transmitted from the motor control section to the single control section.

In this elevator control device, a single control unit detects whether the car is full based only on the car load status transmitted from the motor control unit, and if the car is detected to be full, it does not respond to a hall call.

(Problems to be Solved by the Invention) In standalone control, fullness is detected based on load. Therefore, if the hall is not full, the hall will respond to the call, but in reality, there are many cases in which customers waiting in the hall are hesitant to board the car after seeing the almost full car, and end up not boarding the car.

In cases such as this, where the passengers in the 5 cars can be moved back to the back and several more people can board, the result is that the passengers waiting in the hall are dissatisfied with the long wait and that the train has to stop in vain.

An object of the present invention is to provide an elevator control device that allows passengers waiting in a hall to board the elevator smoothly by guiding passengers in a car that is nearly full to the back of the car. be.

[Structure of the invention]

(Means for Solving Problem 11) In order to solve the above problems, the present invention provides an elevator having means for outputting an assignment command, means for controlling a car based on the assignment command, and means for detecting a load state. The present invention is characterized in that it is equipped with means for detecting the degree of fullness from the load state, and a device for issuing a notification by voice or display function to an elevator that is nearly full but still available for boarding.

(Function) The hall call input control section allocates a hall call generated at the hall. In the case of multiple elevators, the group management control unit grasps the status of all elevators and controls the movement of all elevators.

Then, upon receiving instructions from the hall call input/output control section and the group management control section, the single control section controls the movement of the car.

A full state can be detected by transmitting the motor control unit's car running state and car load state to the single control unit.

On the other hand, car white information is also obtained from the car, and a message is outputted from the data input device by voice or display function to make it easier for passengers waiting at the hall to board the car.

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

1 and 2 are block diagrams of an elevator control device according to the present invention.

10 is a group management control unit, and this group management control unit G includes single control units 1-1. ~1
-N via a high-speed transmission line 12, which is a first transmission control unit. The group management control section 10 and the single control section 1
-1. ~1-N is constituted by a small computer such as one or more microcomputers, and operates under the control of software.

3 is a hall call registration pushbutton provided on each floor, and 5 is a hall call input/output control unit for inputting and outputting a hall call signal.

Group management control section 10, single control section 1-1. -1-N and each hall call input/output control section 5 are connected via a low-speed transmission line I3, which is a second transmission control means.

The high-speed transmission line 12 includes single control units 1-1. 1-N and the group management control unit 10, that is, a transmission control system that mainly performs transmission of control system diffuser pipes in the machine room, and is connected by a high-speed, highly intelligent network. Control information necessary for group management control is transmitted to the group management control section 10 and each individual control section 1-1. ~1-N are exchanged at high speed.

The low-speed transmission line 13 is a control system that mainly transmits information sent via the hoistway, such as the hall call registration push button 3° of each hall and the monitoring panel 11 in the monitoring room. Because it is low-speed and long-distance, it is composed of optical cables, etc., and includes the group management control section 10 and the single control section 1-1. ~
It is connected to 1-N and exchanges data.

When the group management control unit 10 is normal, the hall call registration push button 3 is controlled by the group management control unit 10 via the low-speed transmission line 13, and when the first hall call registration push button 3 is pressed, the hall call gate is closed. At the same time, the unit controller 1-1. is sent via the high-speed transmission line 12. ~1-N
Based on this information, the assignment to the optimal machine is determined, and a response control command is issued to that single machine. The unit control unit that receives the control command performs unit control using the control command as hall call information.

FIG. 3 is a block diagram showing the system configuration of the high-speed transmission line 12 in FIG. 2. Transmission control is microprocessor 1
For example, a data ring controller 16 and a media access controller 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). 17, the configuration allows data transmission to be performed in a highly intelligent manner.

A microprocessor 15 is used for high-speed transmission control.
The configuration reduces the proportion of transmission control software managed by the system.

As a controller that realizes such highly intelligent transmission control, for example, the data ring controller 16 is an LSI i manufactured by Intel Corporation.
82586 is used, and as the media access controller 17, Intel i 82501 etc. are also in practical use, and by using these, IOM
High-speed transmission functions such as 0M pin 8 can be performed relatively easily with a reduced support ratio of the microprocessor 15.

Note that 18 is a system bus, 19 is a control line, and 20 is a serial transmission system.

The above-mentioned method is used to perform data transfer, allocation to hall calls, and other controls.

The operation of the single control unit when a person gets on and off after assignment will be explained with reference to FIG. As explained in FIG. 2, the single control unit receives commands from the group management control unit 10 based on hall call information.

On the other hand, based on the car white information transmitted from the car 2 and the car load signal transmitted from the motor control section 6.

The single control unit 1 determines that the hall is stopped because it is not full and there are waiting passengers in the hall that has stopped.

As an example of this detection method, the motor control unit 6 detects the load and the control information indicates that the hall is stopped due to a hall call and the door opening button is pressed.

The above shows a situation where hall calls are suspended and passengers in the hall are hesitant to board the car because they see the car being nearly full.

In such a situation, an announcement such as "Please move a little further back" is made to the car to encourage the passengers in the car to close the car and create an environment in which it is easy for passengers in the hall to get into the car. The content of the announcement is transmitted by the data input/output device 9.
Allow all kinds of output.

Next, referring to FIG. 4, a flowchart showing the operation of the single control section 1 will be explained.

At a certain timing before the current car stops (step 1), the load is checked and it is determined whether the load in the car is above a certain value (step 2).

The fixed value is approximately (full capacity - 200) kg. In other words, the car is almost fully occupied and passengers are allowed to board the car, but the weight is not particularly limited to (full - 200) kg as long as there are passengers in the cage inside the car. Step 3) Determine whether the car has stopped. Step 3) Check whether the car has stopped due to a hall call. (Step 4) If it is verified that the stop was due to a hall call and the door open button inside the car has been pressed for a certain amount of time. (
Step 5) "Please fill it up a little more. Announce to the passengers in the car, such as J. (Step 6) After the passenger gets on board and closes the door. (Step 7) Perform the normal departure. (Step 8) Announce to the passengers. The message is not limited to voice messages, but if there is a display or other device in the car, the same message can be output on the display as well.

The system configuration diagram of the message output device is shown in Figure 5(a).
(b) Shown in (C). FIG. 5(a) is a block diagram of the single control unit 1 and the information devices 21 and 22 in the car.

The data input in advance in the data input/output bag 9 is transmitted via the transmission line 28. As for the audio output, as shown in FIG. 5(b), the signal generated from the single control unit 1 is received and analyzed by the selection control unit 23, and the audio recording unit 24 selects which message to broadcast based on the result. The message is selected and reproduced by the voice reproduction unit 25 (magnetic head, voice synthesizer, etc.), and a message (here, ``Please move a little deeper'') is transmitted to the passenger through the voice amplification unit 26 and speaker 27.

On the other hand, a block diagram of the display is shown in FIG. 5(C). The signal from the single control unit 1 is sent to the transmission line 2.
The characters and patterns to be displayed are determined from the input signals at the terminal 29 and the CPU 30. This data is sent to the display recording device 31 as image data. Further, the display control section 32 controls the interval and amount of five characters to be sent, and sends the data to the display signal control section 33 via the readout transmission processing section 34 to the display device 35.

As mentioned above, by outputting a message urging passengers to pack up their cars so that as many people as possible can get on the elevator that has arrived at almost full capacity, the dissatisfaction of customers waiting in the hall can be minimized, and mutual interaction can be improved. Smooth elevator use is realized.

In addition, in the operation management of elevators, it is possible to reduce the number of cases in which the elevator stops because it is not full but ends up being wasted if no passengers board the elevator, which also improves the transportation rate.

The present invention is not limited to the embodiments described above, but can be practiced with appropriate modifications within the scope of the gist thereof.

For example, in a case where the car is almost full and the car is not called to the next stop, Chūyo, while the car is running to the Ho stop, the message ``Customers are waiting on the 5th floor. Please wait a little longer so that as many people as possible can board the car.'' An example of this is outputting a message such as "."

〔Effect of the invention〕

People waiting in the hall often hesitate to accept passengers the moment the elevator doors open when the elevator arrives at a nearly full capacity. In the present invention, by prompting the passengers in the car to move to the back of the car by a message (voice or display), the passengers waiting in the hall can board the car smoothly and the dissatisfaction of the waiting customers and long waiting times can be minimized. I can do it.

Furthermore, in terms of operation, stopping is not wasted, leading to improved operational efficiency.
