Abstract

PURPOSE:To improve service for users in transport from a reference floor and in transport between floors, and perform an optimum travel with less waiting time by setting a quasi-office-going hour at a specified time before an office- going hour, and employing both a distributed stand-by and a forced return of elevators on a reference floor when the quasi-office-going hour operation is performed. CONSTITUTION:A group management control computer 5 reads time information from a clock 4 through an input register 9. Based on the time data read, a reference floor service strengthening pattern is set when a quasi-office-going hour operation is performed. Further, out of all numbered elevators, with the numbered elevators in each of which the undirectional condition of a cage is continued for a fixed time, based on the reference floor service strengthening pattern, reference floor service strengthening outputs are outputted to main control boards 1A,..., 1H of the respective numbered elevators through an output register 8. The respective numbered elevators are forcedly returned or put in distributed standby condition on a floor specified in specific order of preference. Thus, much more service can be provided for users by providing the reference floor service strengthening pattern before the office-going hour.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control method.

[0002]

2. Description of the Related Art In recent years, an elevator group management control device to which a small computer is applied has appeared, and it has become possible to provide more advanced services flexibly corresponding to the demand of buildings. For example, in an elevator installed in an office building, the operation pattern of the elevator can be changed depending on the time zone, and each operation pattern can be set at a specific time zone such as when going to work, leaving the office, and having lunch. Operation is being performed in response to changes in the flow. When it is not the above-mentioned specific time zone, the normal distributed standby operation is performed, and the elevator operation is controlled so that the service in the building is uniform.

[0003]

However, in the office building, the number of people who come to the office and use the elevator is considerably large, even before a certain working time in the morning.
In normal distributed standby operation, there is a high risk of causing long waits. In addition, it may be possible to speed up the setting of the time zone of the driving pattern at work in order to overcome the above-mentioned drawbacks, but there was a problem that the inter-floor transportation service deteriorates.

Therefore, an object of the present invention is to improve the transportation service from the standard floor and the inter-floor transportation for elevator users who are a predetermined time before the morning work hours in an office building or the like, and have a long waiting time. An object of the present invention is to provide an elevator group management control method that enables optimum operation control.

[0005]

In order to achieve the above object, the present invention provides a group management control device for managing the operation of a plurality of elevators, in which car calls, car status information and halls of each elevator car. The call information and time information are input and managed, and the elevator standard floor service reinforcement operation is performed based on this car call, car status, hall call, and time information. And a group management control method for elevators, characterized by performing the operation for enhancing the service of the standard floor at the time of semi-attendance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevator group management control according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an elevator group management control device.

The elevator group supervisory control apparatus of FIG. 1 is provided in each unit and inputs a car call signal and a car status signal (car position signal, car traveling direction signal, car load signal, etc.) for each car. Main control panel 1A, 1B ..., 1H to manage
, A wiper select circuit 2 that collectively stores information about car calls and car states input on the main control panels 1A, ..., 1H, and a hall call registration circuit 3 that registers hall calls, and keeps time. Clock 4 and wiper select circuit 2
And a group management control computer 5 which controls the group management of the elevator based on the information from the clock 4.

, 1H, a wiper select circuit 2, a hall call registration circuit 3, a wiper select circuit 2, a wiper select circuit 2 and a group management control computer 5.
Are connected by buses. Here, the group management control computer 5 has output registers 6 and 8 and input registers 7 and 9, executes a program stored in advance based on the information input from the input registers 7 and 9, and outputs the execution result. Output from registers 6 and 8. For example, when the group management control computer 5 needs information on each car and hole, a subaddress signal is sent from the output register 6 of the group management control computer 5 to the wiper select circuit 2 and corresponds to the subaddress in the wiper select circuit 2. Information on the car or the hall is sent to the input register 7 and read. The output register 8 outputs the allocation signal and the distributed standby command signal to each unit, and the input register 9 receives the time information from the clock 4. Next, the operation of the elevator group supervisory control device having the above-described configuration will be described.

First, from the main control panel 1A, ..., 1H and the hall call registration circuit 3, car call information, car state information (car position, car load, car running state, car running direction, car door open / close state, Car free state), hall call information is sent to the wiper select circuit 2, and the wiper select circuit 2 stores each information described above in a RAM (not shown).
(Writing / reading memory). When the wiper select circuit 2 receives the sub-address signal from the output register 6 of the group management control computer 5, it outputs data information to the input register 7 of the group management control computer 5 based on the input sub-address signal. The group management control computer 5 executes a prestored program based on the data information obtained from the wiper select circuit 2 via the input register 7 and the time information obtained from the clock 4 via the input register 9,
A command signal (call assignment signal, split standby command signal) based on the execution result is output via the output register 8 to the main control panel 1 of each unit.
Output to A, ..., 1H. Next, the operation of the group management control computer 5 will be described with reference to the flowcharts of FIGS.

First, the car call data, the hall call data, and the car state data obtained from the wiper select circuit 2 via the input register 7 are initialized (step 1). Next, from the car index J = 0 (Unit A) to J = 7 (H
Up to each car, the car call, hall call, and car status data of all cars are read (step 2 to step 5). After reading the data of all units, the process proceeds to the symbol B1 (step 6), and then the time information is read from the clock 4 via the input register 9 (step 7). Based on the read time data, set a standard floor service enhancement pattern to be described later if it is a semi-attendance time zone (a time zone about 30 minutes before the attendance time zone), and if it is an attendance time zone, a distributed standby pattern II to be described later. If it is neither the semi-attendance time nor the attendance time zone, the normal distribution waiting pattern I is selected and set (steps 8 to 12), and the process proceeds to the symbol B2 (step 13). Next, in all units, it is judged whether the car is in the non-directional state for a certain period of time. The service enhancement output (combined use of forced withdrawal to the standard floor and distributed standby output) is output (steps 14 to 17). Here, Table 1, Table 2 and Table 3 show distributed waiting patterns that represent the priority order of the distributed waiting floors during normal operation, attendance at work, and semi-attendance.

[Table 2]

[0013]

[Table 3]

Table 1 shows a distributed standby pattern I, which is a distributed standby pattern in normal times. Table 2 shows a distributed standby pattern II, which is a distributed standby pattern when going to work. Table 3 shows the standard floor service enhancement pattern, which is the pattern for semi-attendance.

For example, in the explanation of the operation of the above-mentioned flowchart, when it is judged in step 8 that it is the semi-attendance time zone and the standard floor service enhancement pattern is set in step 9, the above-mentioned steps 14 to 17 In the process of No. 1, the units that become free (there is no state to respond to) are forced to pull back or stand by in a distributed manner to the designated floors in the order of priority shown in Table 3. In other words, in the standard floor service enhancement pattern, the first and third free units are forcibly pulled back (to the standard floor), and the second and fourth free units are given priority to the first floor. For the fifth and subsequent free cars, priority will be given to the fifth and eighth floors alternately. Similar processing is performed when the distributed standby pattern I and the distributed standby pattern II are set. In this way, by providing the standard floor service enhancement pattern before the work hours, it becomes possible to further provide services to the elevator users in the building.

The standard floor service enhancement pattern in Table 3 is not limited to this embodiment, that is, 1
It does not matter how to set the service to the floor depending on the degree of strengthening and the service level of the inter-floor transportation.

[0017]

As described above, according to the present invention, in the office building or the like, by providing the semi-attendance time zone before the morning attendance time zone and providing the standard floor service enhancement pattern at the semi-attendance time, Provide elevator group management control method that improves the transportation service from the standard floor and the inter-floor transportation service for elevator users who are a predetermined time before the work time, and enables optimal operation control with little long waiting You can do it.
