Description

[Detailed Description of the Invention] [Purpose of the Invention (Field of Industrial Application) The present invention relates to an elevator group management control device for operating a plurality of elevators for a plurality of floors, and is particularly applicable to intelligent buildings. The present invention relates to a group management elevator control device.

(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, the elevators that respond to hall calls on each floor are equipped with a microcomputer. Currently, small-sized computers such as the following are used to allocate information in a rational and prompt manner. That is, when a hall call occurs, the most suitable elevator to service the hall call is selected and assigned, and other elevators are prevented from responding to the hall call.

Recently, in this type of group management control, models with a learning function have appeared, and it is possible to measure the difference between floors based on learning data such as measuring car call registration data when responding to each hall call in real time, and measuring data on boarding and alighting loads. Traffic volumes and the average time between arrivals at each hole can now be ascertained.

Then, based on the measurement data, the measurement data is processed for each time period to understand the unique demand of each building, determine the optimal machine when a hall call occurs, and set the time for dispatch, lunch, clock-out, etc. It directly responds to group management controls such as setting distributed standby zones during off-peak hours and setting the number of idle machines to save energy.

The group management control device usually performs the above functions in a distributed manner using multiple small computers such as microcomputers, and there is also a single control device for controlling a single elevator that is connected to the group management control device in a master-slave relationship. It is composed of small computers such as microcomputers and is digitized, and information is transmitted at high speed through transmission lines such as serial transmission between computers between the group management control device and the single control device.

As described above, in elevator systems that perform group management control, the entire system is becoming more complex and digitalized, with an increase in the proportion of software controlled by microcomputers and high-speed information transmission between computers.

On the other hand, with the advent of intelligent buildings, which originated in the United States and has been developing mainly in urban areas in recent years, the diversification of building systems has progressed, and buildings are now equipped with complete information and communication systems. hand,
In-building OA support services centered on office automation (hereinafter referred to as OA) systems have developed, information data specific to each building has been prepared, and information communication has been carried out via local area networks (LANs) within buildings. It has become so.

Under these circumstances, in recent years, systems that link in-building telephone lines and elevator systems are being put into practical use.A typical example is VIP operation based on remote control commands from a telephone, and group management elevator groups. A specific one of the elevators is isolated as a VIP-only car, and the elevator in question has the function of providing service only to the dedicated button when there are no more calls.

However, when VIP operation is performed based on the remote control command, the number of elevators under group management control for a certain period of time is reduced, so there is a problem in that the service for other general users deteriorates. Although it is possible to do so, there are restrictions on its use by general users, and because only certain people can use it, it is rarely used, and even if a device is installed to link with the elevator system, it is not cost-effective, and it is difficult for general users to use it. There were problems that made it impossible to improve the service.

(Problems to be Solved by the Invention) As described above, the elevator call service function using the building telephone line in the conventional elevator control device has a negative impact on other general passengers, as typified by the above-mentioned VIP operation. For the reasons mentioned above, most of them are in a form that can only be operated by specific people such as building managers, and they are only used to provide services for important customer visits, resulting in the problem of infrequent use and high costs. there were.

In addition, although we will not be able to make one of the group-controlled elevators completely independent, we will automatically register calls for the five elevators by phone as a function to temporarily allocate one elevator for important customers. However, with such a function, it is unclear how long the elevator will wait after registering by phone, and if the elevator arrives too late or if the elevator is registered for a floor that has already been registered. In some cases, passengers have already finished boarding and alighting the elevator before they reach the landing and the train has departed, and it is likely that they will have to register their call again at the landing. As with the previous method, there were also problems in which the benefits of remote control commands could not be found.

This invention was made to solve these conventional problems, and allows elevator reservations to be made by inputting information such as the destination floor and the number of people using a telephone line, as well as remote control commands. By determining the answering machine and notifying the requester of the confirmation response at the timing of arrival, it can be used by general users, eliminates waiting time at the boarding hall, and can be used by other halls. It is an object of the present invention to provide a group management elevator control device capable of improving an elevator pulling service function by remote control using a telephone without causing a deterioration of service in group management control due to calls.

[Structure of the Invention] (Means for Solving the Problems) The group management elevator control device of the present invention is connected to a building premises telephone line, accepts elevator reservations based on operation commands from the filling machine, and when the corresponding elevator responds. an interface unit that notifies a telephone of the destination of an operation command request via the telephone line; The operator selects and responds to the most suitable elevator, and also selects and allocates the most suitable elevator among the elevators in service in response to the operation command inputted from the telephone via the interface unit, and the allotted elevator no. and a group management control section that provides the information to the interface section.

(Function) In the group management elevator control device of the present invention, the group management control section puts a plurality of elevators into service for a plurality of floors,
Perform predetermined evaluation calculations for hall calls that occur,
Select the 81M elevator and have it respond.

In addition, for this group management control, it is connected to the building premises telephone line via the interface unit, and accepts elevator reservations based on operation commands from the telephone.

The interface with the building local telephone network system in the group management elevator control device 4 is connected to each control section of the elevator via the elevator system interface section 5.

The group management elevator control device 4 has a high-speed transmission system for information transmission between the group management control unit 6 that administers group management control and the individual control units 7-1 to 7-N that control each elevator individually. They are physically connected via a system 8 and a low-speed transmission system 9.

The group management control section 6 and the individual control sections 7-1 to 7-N are constituted by a plurality of small computers such as microcomputers, and operate under the control of software.

There is one high-speed transmission system 8, and each single control unit 7-1 to 7
A transmission control system that performs transmission between the -N and the group management control unit 6, that is, mainly between the control computers in the machine room,
forming a high-speed, highly intelligent network. Control information necessary for group management control is exchanged at high speed between the group management control section 6 and the individual control sections 7-1 to 7-N via physical transmission lines.

The low-speed transmission system 9 is connected to a hall call unit 10-1 on each floor.
This is a transmission control system that mainly transmits information sent via optical paths such as ~10-M, and its transmission speed is lower than that of the driving operation phrase transmission system 8.

Since this low-speed transmission system 9 is generally long-distance, it is composed of an optical cable or the like, and is connected to the group management control section 6 and a single t!
Data is exchanged with the E control units 7-1 to 7-N.

Hall call units 1o-j to 10-M and low-speed transmission system 9
Transmission control units 1 i-t to 11-M are interposed between the two to control the exchange of information between the two.

If the group management control section 6 is normal, the hall call unit 1
Hall calls from 0-1 to 10-M are transmitted to the group management control unit 6 via the low-speed transmission system 9 and controlled, and when the hall call is registered, a registration lamp is set and the high-speed transmission system 8 Single control units 7-1 to 7 sent via
-Determine the optimal machine based on the information from N, and issue control commands to that single machine.

The unit control units 7-1 to 7-N that received the control command then use the 1llJ command as hall call information to control the unit 11.
Perform i1J control.

The elevator system interface unit 5 connects the high-speed transmission system 8, which is the elevator LAN, and the telephone outlet 2.
A telephone input/output control unit 12, which is a remote operation control function unit having two interfaces of the building premises telephone network system via the building premises telephone network system, and controls input/output functions with the building premises telephone exchange 3, as shown in FIG. Also, in conjunction with the input/output control section 12, there is a voice synthesis control section 13 which controls a guidance notification function during a call with a request destination Bush type telephone, and an elevator 1-A.
It is composed of a group management input/output control section 14 that controls input/output functions with the N high-speed transmission system 8.

A database for converting signals obtained by inputting and outputting from the telephone exchange 3 and the elevator LAN high-speed transmission system 8 and for notifying the voice guidance of the voice synthesis control section 13 is constituted by a small computer such as a microcomputer. It operates under software management and has a configuration that allows changes to data and logic.

The input/output control functions in the elevator system interface section 5 are roughly divided into two systems. The input/output signal flow of the first system is based on the Bush type telephone IT in buildings and offices, etc.
The elevator control system terminal is accessed by pressing the button from the IJ, . . . , and remote control command information is input by pressing the button after the data link is established. This is a system that outputs request commands.

The input/output signal flow of the second system is controlled by the group management control unit 6 according to the elevator response number selection and response to the request command.
This is a system for outputting remote control request response information to the corresponding terminals of the request destination bush type telephones 11, IJ, . . . via the telephone terminals of the elevator control system.

The operation of the group management elevator control device having the above configuration will be explained next.

3(a) and (b) are flowcharts showing the control function operation of the elevator system interface unit 5, and FIGS. 4 and 5(a) and (b) are flowcharts showing the control function operation of the group management control unit 6 It is a flowchart showing the operation.

Bush type telephone 11, I installed in the office in the building
Enter the code for remote operation mode from any telephone in J, . Upon establishment, data such as boarding floor, destination floor, number of passengers, etc. for elevator response are input in sequence, and once the data link is released.

When the group management elevator control device 4 accesses the elevator response request, the elevator system interface section 5 executes the control operation function shown in the flowchart of FIG. 3(a).

The code data of the request destination terminal is stored via the telephone input/output control unit 12 (step S1), and is later used for setting the destination terminal of the request response command by elevator response (step S2).

The Bush type telephone 11. The remote control command information from the IJ, . . . is sent to the group management 1 via the group management input/output control unit 13.
An elevator response request command is output to the 1i1J control section 6 (step s3).

The information input to the group management control unit 6 via the elevator high-speed transmission system 8 is transmitted to the group management control unit 6 as shown in FIGS. 4 and 5 (
According to the control operation functions shown in the flowcharts a) and (b), a response machine selection is carried out which is different from the evaluation algorithm for selecting a response machine based on a normal hall call.

Usually, hall call buttons 10-1 to 10- are located in each hall.
When an elevator response request command is input to the group management control unit 6 via the elevator LAN low-speed transmission system 9 due to the registration of M, an elevator that responds immediately is assigned and a hall lantern, chime, etc. is sent to the passengers in the hall. Make announcements.

However, in the remote control command according to the present invention, since the arrival of the responding elevator is notified using the same building telephone line at the time of response, the elevator is assigned a hall to each floor compared to the above-mentioned normal hall call assignment. Compared to normal allocation evaluation, which uses the expected call arrival time as the main element, priority is given to matching scheduled stop floors and securing the number of passengers, and the allocation evaluation takes into account the impact on elevator operation efficiency.

For this purpose, as shown in the flowchart in Figure 4, within a certain period of time (Limit (1) setting 1
In the case of i, a search for selecting the car No. ii is carried out by the responding car selection process (1) whose details are shown in the flowchart of FIG. 5(a) (step 321 in FIG. 4).

In other words, according to the flowchart in Figure 5(a), based on the boarding floor, destination floor, and number of people data values input at the time of the remote control command, both the boarding floor and the destination floor are already scheduled to stop, and the boarding floor at the boarding floor is A search is performed for the machine in which the expected number of possible people is less than or equal to the number of people reserved at the time of remote control command (step 82).
11-215).

The response machine selection evaluation condition of this response machine selection process (1) is that by selecting as the response machine a machine whose stop schedule has already been determined for both the boarding floor and the destination floor, the overall operation of the elevator is improved by increasing the number of floors at which the elevator stops. This evaluation takes efficiency improvements into consideration, and is effective in improving group management performance, and is different from evaluations for normal hall call assignments.

If the optimum machine that meets the response conditions is not found even after the limit (1) set time has elapsed (see step 3 in Figure 4).
22, 323), the response machine selection process (1) and (2) selects and searches for the optimum machine until the limit (2) set time elapses (steps 324 to 3 in Fig. 4).
26).

This responding machine selection process (2) is performed as shown in detail in the flowchart of FIG. 5(b).
), an optimum car selection search is performed as a condition for permitting an evaluation in which conditions are applied to cars for which stop schedule conditions have already been determined (steps 8241 to 5245).

Then, only if a car that meets the conditions of response car selection processing (1) and (2) is not found within the limit (2) set time, priority based on stop floor matching and load is canceled, and the normal hall call is performed. Using the same evaluation algorithm as the allocation evaluation, an allocation command is issued to the appropriate control units of the single control units 7-1 to 7-N via the elevator LAN high-speed transmission system 8 to the optimum machine, and a certain period of time before the optimum machine responds. Elevator LAN at
A response command to the corresponding remote control command is output to the elevator system interface unit 5 via the high-speed transmission system 8 (step S28° 829 in FIG. 4).

In the elevator system interface unit 5, the response command data is inputted via the group management input/output control unit 13 according to the flowchart shown in FIG. Steps 331 to 534), in which a data link establishment request command is issued to the caller, and then, in the call established state, the speech synthesis control unit 14 sends a preset voice guidance to the answering machine and a response to the effect that it will arrive soon. The guidance is output (step 335), the data link is released from the elevator system interface unit 5 side, and the series of operations ends (step 536).

In this way, the group management elevator control device of this embodiment puts a plurality of elevators into service for a plurality of floors, and performs group management control of elevators that selects and responds to a common hall call by selecting the most suitable elevator. In addition, by connecting to the building's telephone line and accepting elevator reservations through remote control from the telephone, and when the corresponding elevator responds, a response command guide is notified to the destination of the operation command request, so that the elevator can be started using the remote control function. In addition to realizing the pull service function, by using information during remote operation and response guidance notification to the destination of the operation command request, it is possible to realize the dispatch of the pull elevator without reducing the operating efficiency of the elevator, and to realize the dispatch of the pull elevator without reducing the operation efficiency of the elevator. It is possible to realize a remote control service function that does not cause any deterioration in service and does not impose any restrictions on the use of general users.

[Effects of the Invention] As described above, according to the present invention, a remote control terminal of a building telephone exchange is connected to a telephone line, and elevator reservations can be accepted based on operation commands from the telephone and the request destination from the group management control unit can be received. Elevator response guidance is provided by corresponding elevator response commands, so VIP operation by remote control is no longer possible, and the frequency of use of the system is increased by using the in-house telephone line that can be used by general users. can be done. Furthermore, since elevators can be dispatched without reducing the operating efficiency of the elevator, the telephone remote control service 81 function can be realized, which eliminates the waiting time for users in the elevator hall and allows them to board the elevator reliably.
