Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control system, and more particularly to a group management control device for automatically determining an operation mode and a side-by-side elevator control system provided with a guide device at each floor.

[0002]

2. Description of the Related Art In recent years, as buildings have become taller and larger, there is an increasing demand for improved transportation capacity for elevators and improved usability in accordance with the purpose of the building. Especially when going to work,
It is strongly desired to improve transportation capacity during congestion such as lunch.

As a method for improving the transportation capacity at the time of congestion as described above, Japanese Patent Publication No. 43-25097 discloses that time elements and traffic demand satisfy predetermined conditions.
It is disclosed that the service floor of an elevator is divided into a plurality of zones and divided express operation is performed. Further, Japanese Patent Application Laid-Open No. 57-203668 discloses that the number of divided vehicles in the divided express operation is automatically set by performing a trial operation. In addition, Japanese Patent Publication No. 62-12148 discloses that the divided floors of the divided express operation are automatically set by the trial operation. Further, in JP-A-59-177264, daily users or load is measured for each floor, and during the express express operation, all floors are divided according to the measured data so that all floors have a predetermined ratio. It is disclosed that the floor is automatically set. Further, Japanese Patent Publication No. 5-32303 discloses a display panel that is easy to see and understand in an automatic operation management system elevator.

On the other hand, as guide display devices for elevator halls, devices using LEDs and liquid crystal screens are becoming widespread, and it is possible to display various kinds of information such as the operating status of elevators and general-purpose information.

[0005]

In the time zone when elevator users are concentrated, such as when going to work or during lunch, the split express operation as described above is effective for improving the transportation capacity. It is necessary to inform the user of the service floor in an easy-to-understand manner in order to perform proper driving. If the display is unclear, the user may get in the wrong vehicle and, on the contrary, reduce the driving efficiency. Especially when the service floor is different, people who are used to using the elevator are more likely to get in the wrong vehicle. However, if the display or voice guidance is changed too often, or if extreme display or guidance is given, the view of the building will be destroyed, which will cause a problem of noise and cause complaints from customers. In order to solve the above problems, a first object of the present invention is to clearly inform the user of the change when a change in operation mode such as split express operation or change of service floor occurs from normal operation. It proposes a guidance method. In addition, for other purposes, by minimizing the duration of guidance changes, customer complaints are prevented in advance, efficient operation such as split express operation is effectively performed, and an elevator with high transportation capacity is provided. To do.

And the guide means of

[0007]

According to the present invention, in a side-by-side elevator control system that automatically sets an operation mode such as a divided floor zone and the number of elevators for each elevator such as a split express operation, the operation automatically set results in the past set operation. If it is different from the mode, the user clearly recognizes that the change has been made by changing the color and the guide form, and it is possible to switch the elevator to be used, and the effect of split express operation as expected Can be raised to Further, by minimizing the duration of changing the guide, it is possible to prevent complaints from customers without damaging the view of the building.

[0008]

The present invention will be described below with reference to FIGS. 1 to 12.

FIG. 1 shows a system configuration diagram of the present invention. The system according to the present embodiment includes a group management control device X01 that performs group management control of four elevators, a unit control device X02-A to D that controls operation of each elevator, and a guide device installed near the entrance / exit of each elevator. X03-A1
To An, X03-B1 to Bn, X03-C1 to Cn, X
03-D1 to Dn, voice guidance devices X04-A1 to An,
X04-B1 to Bn, X04-C1 to Cn, X04-D
1 to Dn, and hall call registration devices X05-1 to Xn installed in each floor hall.

Next, the group management control device X10 will be described. The machine state table T01 receives the data transmitted from the elevator machine control device X02 to the group management control device X01 via the group and machine transmission program P01, and updates and sets the data periodically or immediately after the change. This data includes information about car load (number of people) and number of passengers, etc. for detecting traffic demand, elevator position and speed information, hall guidance device guidance status, car call registration status,
It consists of input information such as the door open / close status.

Utilization information collection and erroneous operation detection program P0
1 refers to the schedule data table T02 to see what kind of operation mode is operating for each hour, calls the hall, the elevator control table contents, and the detection data for the number of people getting on and off each floor for each car. Sampling is performed at every collection or every fixed period, and data for learning programs of various traffic information and simulation and calculation of control parameters thereof is collected. Further, this program is a program that counts as an erroneous operation when a car call button on the floor that is not in the guidance is operated, obtains the erroneous operation probability, collects the data, and accumulates the collected data in the traffic information and the usage situation accumulation table T04.

An operation mode planning program P03 for performing simulation using GA (genetic algorithm)
Calculates the best combination of operation modes from simulations based on the traffic information and the data in the usage status accumulation table T04 by using simulation,
Operation mode planning table T08 by A simulation
It is a program to record in. The operation modes include normal operation, express operation, guided express operation, management operation, and other operation methods, as well as restrictions on hall call registration, selection of hall call allocation method, car call registration restriction, door opening / closing control time control, etc. It is composed of data of elevator control restrictions. The operation mode to be created is limited by the customer request table T03 created according to the customer's request specifications. In addition, it is assumed that several operation modes are simultaneously created for one operation method, and in this embodiment, two operation modes are used.
Types shall be created. Although not shown in the figure, the customer request table can be freely rewritten by the customer by an external input means.

The traffic demand judgment program P04 judges whether or not the operation mode should be changed based on the traffic demand element based on the traffic information and the use situation accumulation table T04, and the operation mode plan / command program P08 needs to be changed. Inform the presence or absence.

Next, the operation mode plan and command program P
The operation of 08 will be described with reference to the flowchart of FIG.
First, it is determined from P01 and P04 whether or not there is an instruction to change the operation method depending on the schedule and traffic demand. If there is no command, the process ends. If there is a command, the process proceeds to S120 and two types of operation mode data suitable for the time element and the traffic demand element at that time are read from the operation mode planning table T08 by GA simulation. Next, in S130, the machine state table is read online, and in S140, which of the two types of operation mode data is better is determined by simulation, and the data is corrected as necessary to create an operation mode.
In S150, it is determined whether or not the transportation capacity becomes a predetermined value (10%) or more by setting the created operation mode. When the transportation capacity is equal to or greater than the predetermined value, the process proceeds to S160 and the created operation mode is recorded in the operation mode plan / command table T11.

In the operation mode plan and command table T11, in addition to the operation methods such as normal operation, express operation, guided express operation, and management operation, there are restrictions on hall call registration, selection of hall call allocation method, and car call It contains data on elevator machine control restrictions such as registration restrictions and control of door opening / closing control time, and the data that directly requires machine control is entered in the elevator control data table T10.

The guidance method selection program P05 operates like the flow chart shown in FIG. That is, S2
At 10, the operation mode plan and command table T11 are read to determine whether the operation mode has been changed. If it has not been changed, the process proceeds to S280. If there is a change, the process proceeds to S230 and guidance data is selected according to the driving method. Next, the procedure proceeds to S240, in which it is determined whether the selected guidance data is the same as the previous same operation method by comparing with the guidance method history table T06. If they are different, the processing proceeds to S250, and if they are the same, S260. To each.
Guidance method history table T06 As shown in FIG. 6, a guidance mode is provided for each driving method, and the guidance data, the display time zone, and the data such as the display date closest to each guidance mode are stored for each display device. It can be compared with the contents displayed in the past in the same operation method. The guidance modes 1 and 2 are the control mode and the normal guidance mode, respectively. Since it is sufficient to provide guidance suitable for the elevator state at that time, it is not necessary to leave a history. Also, the above data structure is not a display date, but a day of the week or a weekday,
A table may be provided for each day like a holiday. In S2501, the guide data is modified so that appeal guidance is provided, and the process proceeds to S280. In S260, it is determined whether or not the erroneous operation establishment is less than or equal to a predetermined value (3%). If not, the process proceeds to S280 as it is. If it is, the appeal guidance is canceled if the appeal guidance is provided. Change the guidance method command table to, and proceed to S280. In S280, after performing these processes, guide data including the machine state table T01 is created and recorded in the guide method setting table T07.

The display voice code creation program P09 creates a display / voice control code according to the data in the guidance method setting table T07 and records it in the display / voice control code setting table T12.

The hall call registration program P02 is for registering new hall calls registered in the hall call registration devices X05-1 to X05-n in the hall call registration table T05. The hall call allocation program P07 is an operation mode plan / command table. The new hall call registered in the hall call registration table T05 according to the hall call restriction data of T11 is assigned to each elevator and recorded in the hall call assignment table.

The group / number control program P10 is each data created by the group management controller X01 via the network transmission line L01, that is, the hall call assignment table T09,
Each data of the elevator control data table T10, display, and voice control code table T12 is transferred to each unit controller X.
02-A to D are programs that are periodically transmitted. Next, the processing of the machine controller X02-A to D will be described with reference to the machine controller flowchart of FIG.

When the power is turned on, the machine controller performs a reset start of S300 and performs an initial process of S310. Thereafter, the car call process of S320 and the car operation status display process of S330 are performed, and the display and voice control code data transmitted from the group management control device in S340 and S350 are respectively transmitted using the network transmission lines L02-A to D. Guide device X03-A1 to An, X03-B1 to Bn, X03
-C1 to Cn and X03-D1 to Dn are transmitted. In addition, elevator control processing is performed in S360.
Returning to 320, this processing is repeated at a constant cycle.

Next, the guide device of this embodiment is installed in the HX1 of FIG.
A case will be described in which such a 4-panel 8-half-width character LED display device is used. Each of the four panels a to d is composed of 16 * 16 LEDs, and various displays are possible in addition to one full-width character and two half-width characters. It goes without saying that this can be applied to other LED displays or liquid crystal displays. There are two types of transmission format to the display, HF1 and HF2.
The F1 transmission format allows complicated display, but it requires periodic communication between 0.1s and 1s.
20 bytes when 20 bytes of data are communicated for 8 floors in a transmission method such as RS-422A communication * 11
(Bit) * 8 (floor) / 4800 (bps) = 0.37s. Therefore, the load is so high that it cannot be practically used. Therefore, HF1 requires high-speed transmission.

In the HF2 format, since the movement of the display is designated, once transmitted, it is not necessary to transmit the data until the data is changed. Therefore, RS-422A
Even a low-speed transmission system such as the above can be sufficiently supported.

FIG. 7 is a diagram showing the relationship between each operation method and a predetermined value of the error operation probability. When the control mode is severely restricted such as a split express operation when going to work, the error operation probability is a predetermined value. Is set to a low value and the control mode is set to a high value, so that a decrease in operating efficiency can be suppressed.

FIG. 8 is a diagram showing an example of an embodiment when going to work. X03-D1-1 is on the first floor of Unit 4
7 is a display example of normal guidance mode 2 in FIG. 6 . L P 12-
A indicates that the hall call in the UP direction was registered in Unit 4, and the waiting time is displayed by the area occupied by the lamps of different colors. LP11-B shows the current car position of Unit 4, LP11-C shows the traveling direction of the car of Unit 4, and LP11-D shows the movement of the door on the other floor of Unit 4. In this way, by displaying the current state of the elevator to which the hall call is assigned in normal times, the user of the assigned elevator is guided and the annoyance of waiting passengers is prevented. On the other hand, when performing a split express operation on the Y01 service floor when going to work, it is necessary to inform the passengers of the current elevator allocation status and guide the waiting passengers efficiently, so X03 is more effective than the normal display. As shown in -D1-2, it is necessary to give priority to the user to be informed of the information on the service floor of the No. 4 machine by displaying the guidance mode 3 in FIG. When the building, which was controlled on the service floor of Y01 due to factors such as tenants moving, comes to work due to changes in traffic demand, the operation mode plan of FIG. 1 and the data in command table T11 have changed, such as Y02. When the service floor is reached, the display is X03-D1-3 to inform the user that the service has been changed. This changed like LP11- B- A
In the display part of the point, only the changed display part has a different display form from the other displays, and in the example shown in the figure , the changed part is appealed (display in the noticed color instead of the white part) Needless to say that). Further, by giving a voice guidance such as A01, it is possible to call attention to the user and prevent an erroneous boarding due to the change of the service floor.

FIG. 9 is an example of an embodiment of floor-by-floor guidance display when going to work when the service floor is Y01 shown in FIG. Y01A is a display example of all units and floors. X03
-D0-11 is a display example of Unit 4 on the B1 floor where there is no elevator to service at work. The entry prohibition mark, the time when the entry is prohibited, and the reason why the entry is prohibited are displayed to encourage the use of stairs. At this time, since the display time zone is also stored in the guidance method history table T06, it is possible to display an appeal even when the display time is different. X03-D1
-11 is a display example of Unit 4 on the first floor. this is,
This is an example in which an UP hall call is assigned, and the assigned direction, waiting time, and destination floor are displayed. X03-
D2-11 is a display example of Unit 4 on the second floor. This is because the 2nd floor of Unit 4 is a non-service floor, so an entrance prohibition mark and the reason are displayed to guide other elevators. This is the same display on the 3rd to 7th floors. X03-
D8-11 shows the display on the 8th floor of Unit 4. Since no hall call is assigned as in this figure, only serviceable floors are displayed. The same applies to the 9th to 12th floors and the 14th floor. X03-D13-11 is a display example on the 13th floor of Unit 4. Passengers are rarely concentrated at work except on the first floor, which is the lobby floor,
If a hall call is assigned, the display will be the same as in normal times.

FIG. 10 shows an example of a notice display when leaving work. On the previous day, Unit 4 had a display such as X03-D1-2 on the first floor in order to perform a split express operation when going to work on a service floor such as Y01 in FIG. However, since the traffic demand of the building changed, it was necessary to change to the service floor of Y02 of FIG. 8 from the next day, and the operation mode plan of FIG. 1 and the data of the command table T11 at the time of work changed, such as Y02. When the service floor is reached, X03-D8-1, X03-D8-2, X03-D will be available in advance for Unit 4 when leaving work.
Guidance mode 6 to switch between 8-3 and 3 display
By displaying, it is possible to inform which elevator should be used at the time of the next sunrise work. In addition, this display can show only those who need it by displaying only the elevators to which hall calls in the DOWN direction after the waiting time are assigned.

LP18-A displays the waiting time for a hall call in the DOWN direction, and LP18-D displays the opening / closing status of doors on other floors and the presence / absence of passengers. X
03-D1-3 is a display example of the first floor of the fourth car on the day of change. In the figure, the notice display is a switching display method, but there is no problem if this is scroll display. In addition, as a matter of course, the operation mode plan and the command table T1
The contents of No. 1 can be changed from an externally provided input device, and the above-mentioned display modes are switched by inputting an external input to change the operation mode from the next day. This input is possible at any time, and it goes without saying that the operation mode switching may be input in advance by designating a deadline.

FIG. 11 shows an embodiment in which one elevator fails during the split express operation in the first half of lunch. When doing a split express operation at the service floor of Y03 at lunch time, Unit 2 on the first floor is X03 in guidance mode 4.
-Displays like B1-1, and Unit 4 is X03-D1
Display like -6. At this time, it is said that a failure occurred in Unit 2 and service was impossible. In this case, services on the 6th to 10th floors are significantly reduced. P08 of FIG. 1 recognizes the abnormality of Unit 2 by T01, and automatically prevents the operation mode plan and command table T11 of FIG. 1 in order to prevent service deterioration on the 6th to 10th floors, for example, to assign service floors such as Y04. Change it. At this time, the display on each 1st floor is guidance mode 1 in which No. 2 is informed of failure like X03-B1-2.
Is displayed, "Failure occurred" is displayed and X03-
The serviceable floor is displayed like D1-7. At this time, the service floor will be changed drastically in a short time, so a blinking display will be displayed. In addition, voice guidance such as A02 is also given to call attention to the user. In order to set the all-floor service elevator at the time of split express like the No. 4 machine of Y03, it is determined by the customer request table T03 of FIG. At this time, the hall call button is displayed as "normal" or "express" on the hall call button as shown in FIG. 12X06-15, X06-25.
The elevator will be called to the person who wants to get on.

FIG. 12 shows an embodiment in which the split express operation in the first half of lunch time is not limited to the car call but is limited to the display, the hall call and the door opening time. The service floor of each elevator is Y05, and the display on the 5th floor, which is the dining room floor, is X03- in the guidance mode 4, respectively.
A5-10, X03-B5-10, X03-C5-10,
It looks like X03-D5-10. HLT1 is a hall lantern and indicates that an elevator in the DOWN direction has arrived. If a car call not displayed on the display is registered at this time, the service is provided, but it is detected as an erroneous operation by the utilization information collection / misoperation detection detection program P01 in FIG. The percentage is calculated based on how many times it has occurred, and when it becomes larger than 20% of the predetermined value of the manipulation error probability defined in FIG. 7, X03-
A5-11, X03-B5-11, X03-C5-1
The display blinks like 1, X03-D5-11. At the same time, voice guidance such as A03 is given to call attention to the user. Further, when the erroneous operation probability becomes 15%, it is possible to prevent the customer from complaining that the display is intense and the voice is troublesome by canceling the blinking display and the voice guidance. Further, when the erroneous operation probability is further lowered, it is possible to control the car call when the erroneous operation probability becomes less than 3%, for example.

EFFECTS OF THE INVENTION According to the present invention, in a case where the divided floor zones and the number of elevators such as a split express operation are automatically set to the optimum operation mode for each building during congestion such as attendance at work and lunch, If the result of automatic setting is different from the past driving mode due to changes in traffic flow, you can clearly inform the user of the change by changing the color and changing the guidance mode. There is an effect that it is possible to switch between vehicles without any mistake, and it is possible to prevent a decrease in transportation capacity even during high traffic demand such as split express operation.

Further, by measuring the probability of erroneous operation and canceling the setting such as changing the guide according to the result, the duration of the change of the guide can be minimized to prevent the landscape of the building and the customer's trouble. Can be prevented from occurring.

Further, by performing the divided express operation only by controlling the guide device without restricting the car call registration, even if the car call registration button not in the guide is registered, the service can be provided on that floor. , Passengers who get in the wrong vehicle can certainly reach the destination floor.
