Description

Elevator control method and elevator control system

Technical Field

The present invention relates to an elevator control system.

Background

At present, a plurality of elevators are installed in buildings such as buildings, facilities, and the like, and a user uses a car that arrives at a landing where the user gets into the car. In such elevators, the elevator needs to be called to get to the boarding floor. For this call, patent document 1 describes a technique of using a mobile terminal. Patent document 1 includes: an elevator control device for controlling the operation of the car; and a wireless signal device provided at the landing, which transmits a wireless signal at the landing of any floor, starts the application software for call registration pre-installed in the mobile terminal, and transmits a preset destination floor of the user to the elevator control device by starting the application software of the mobile terminal. An elevator system is disclosed, in which an elevator control device registers a destination floor of a user as a landing call, and a car is made to respond to the registered floor of the landing call.

Here, in patent document 1, when a call registration is made for a plurality of elevators by a mobile terminal, a group management control device for an elevator selects a car that can respond to the call and responds to the call from the mobile terminal.

However, in patent document 1, the group management control device of the elevator needs to select a car to which call registration is assigned. In patent document 1, if a plurality of elevators are provided in a building, all of the cars are called. Therefore, when an elevator having no group management function is provided, it is necessary to newly install the group management control device. In addition, even when the group management function is provided, it is necessary to add a car selection function for selecting a car to the group management control device.

Detailed Description

An embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, the user is set to use any one of the elevator a machine 16 to the elevator C machine 18 installed in the building 1. In addition, the building 1 performs a remote operation by the monitoring center apparatus 3 provided at the monitoring center 2. In fig. 1, all elevators of one building 1 are described as remote operation targets, but the monitoring center device 3 may be configured to have a plurality of elevators divided in groups as management targets, for example. The number of elevators is not limited to 3 as shown in fig. 1, and may be 1 or more.

First, the functional block diagram shown in fig. 1 shows the functional configuration of the elevator system in the present embodiment. In the elevator system, portable terminals 19 and 20 such as smart phones, various devices installed in a building 1, and a monitoring center device 3 installed in a facility and a monitoring center 2 are connected to each other via a public network 90.

Here, the mobile terminals 19 and 20 are held by the respective users, and a remote call request application for calling the elevator is installed. The mobile terminals 19 and 20 can be realized by information processing devices such as mobile terminals including smart phones, tablet computers, mobile phones, and notebook PCs. The mobile terminals 19 and 20 may be realized by smart devices connectable to smart phones and the like. In fig. 1, 2 mobile terminals 19 and 20 are shown, but the number is not limited to this number. The mobile terminals 19 and 20 described later may be used outside the building 1 by the respective users.

The monitoring center device 3 is provided in the monitoring center 2, and includes a data transmitting/receiving unit 5, an elevator control unit 6, a call registration storage unit 7, and an elevator master DB8. The data transmitting/receiving unit 5 receives a car call request (hereinafter referred to as a car call command) 28 transmitted from the mobile terminals 19 and 20 via the public network, and the elevator control unit 6 uses the car call command 28 received by the data transmitting/receiving unit 5 to call an elevator, that is, generates a car call command for controlling the operation (running) of the elevator. The call registration storage unit 7 temporarily stores the generated car call command 28. Therefore, the call registration storage section 7 is preferably realized by a so-called memory 23. The car call command 28 will be described in detail later.

The elevator master DB8 stores elevator master information 30 described later. Therefore, the elevator main DB8 is preferably implemented by a storage device called a so-called memory device or the like. The elevator main DB8 may be constituted by a frame different from the monitoring center device 3. In this case, the elevator main DB8 is implemented by a file system connected via a network.

The building 1 is provided with a communication device 9, a plurality of elevators 16 to 18, and monitoring devices (a monitoring device a10, a monitoring device B11, and a monitoring device C12) for managing the elevators. The communication device 9 receives the car call command 28 from the data transmitting/receiving unit 5 and transmits it to the monitoring devices 10 to 12. In this case, the car call command 28 may be directly transmitted to the control devices 13 to 15.

The monitoring devices 10 to 12 monitor the operation states and faults of the elevators (elevator a machine 16, elevator B machine 17, and elevator C machine 18), but may have a function of remotely controlling the respective elevators in accordance with a command from the monitoring center device. The control device, also called a control panel, is provided in the lifting path, the machine room, etc.

The monitoring terminal 4 is connected to the monitoring center apparatus 3 via the public network 90. The monitoring terminal 4 can be realized by a computer device, and can transmit an instruction to the monitoring center device 3 and can output the processing content of the monitoring center device 3. The monitoring terminal 4 can output the operation states of the elevator a-16 to the elevator C18. The monitoring terminal 4 may be connected to the monitoring center apparatus 3 not via the public network 90 but via an internal network of the monitoring center 2 such as an intranet. The monitoring terminal 4 may be provided in the monitoring center 2 or may be externally used.

Next, the hardware configuration of the monitoring center apparatus 3 of the present embodiment will be described with reference to fig. 2. The monitoring center apparatus 3 is implemented by a computer apparatus or the like. The monitoring center apparatus 3 connects the network I/F2100 (network interface) 21, the processing unit 22, the memory 23, the storage device 24, and the like to each other via a communication line such as a bus. The network I/F21 constitutes a data transmission/reception unit 5 that uses NFC (Network Interface Card ) or the like for connection and communication with the outside of the public network 90 or the like.

The processing unit 22 is a processing device such as a CPU (Central Processing Unit central processing unit), and executes software modules stored in the memory 23 with reference to data stored in the storage device 24.

The memory 23 stores an elevator control unit 6, a car call command generation unit 26, and a car call command collection unit 27.

The car call command generating unit 26 generates a car call command 28 by referring to the elevator main information 30 stored in the storage device 24, based on a car call request from a user. At this time, the car call command aggregating unit 27 aggregates, as one car call command, car call requests which can be aggregated as one car call command among car call requests from a plurality of users received in a certain period.

When a car call command generated by the car call command generating unit 26 is issued to the control device 13-15 via the monitoring device 10-12, the elevator control unit 6 causes the call registration storage unit 7 to store the car call command.

The storage device 24 stores elevator master information 30 corresponding to the elevator master DB8, and the elevator master information 30 stores which elevator is installed in which building. The call history storage unit 70 stores call histories from users. The history is not stored in its entirety, but a predetermined period or number of pieces is recorded. The history can be used to preset a call floor and a destination floor of the user.

The storage device 24 can be realized by an HDD (Hard Disk Drive), an SSD (Solid State Drive: solid state Drive), or the like.

Next, information used in the present embodiment will be described with reference to fig. 3, 4, and 8. Fig. 3 shows an example of elevator main information 30 used in the present embodiment. The elevator main information 30 is information associating a building ID for identifying the building 1 with elevator ID, which is elevator identification information for identifying an elevator installed in the building 1.

In fig. 3, the elevator main information 30 is configured to record 1 elevator ID as 1, but is not limited to this configuration. For example, 1 building ID may be set to 1 record, and a plurality of elevator IDs may be included in 1 record. As described above, the building ID is an example for identifying the management unit. Therefore, such unit identification information for identifying the management unit may also be used.

Fig. 4 shows an example of the car call command 28 used in the present embodiment. The car call command 28 is a command generated in response to a car call request from a user, and is information associating a control request ID41, a call floor 42, a destination floor 43, a building ID44, and an elevator ID45 with each other. The control request ID41 is used to identify a car call request from a user. Call floor 42 represents the floor at which the user wishes to take an elevator landing. The destination floor 43 represents the floor at which the user is going down the elevator. The name of the call floor or the destination floor is expressed without limiting the landing floor, the destination floor, or the like.

Building ID44 and elevator ID45 are determined with reference to elevator master information 30.

Fig. 5 is a flowchart showing an example of car call processing according to an embodiment of the present invention. A user of the elevators 16-18 provided in the building 1 sets an elevator for use in an application installed in the portable terminal 19-20. Specifically, the portable terminals 19 to 20 read an identifier such as a two-dimensional bar code provided at the hall, and set the identifier. In this case, a specific elevator may be set, or a plurality of elevators installed in the building may be set together.

The application may also be implemented by an application of a social networking service that is capable of transceiving messages including Short Message Service (SMS).

First, in step S1, any one of the mobile terminals 19 to 20 (hereinafter, referred to as mobile terminals) generates a car call request and transmits the car call request to the monitoring center device 3. At this time, the set building ID, elevator ID, inputted call floor, destination floor, and the like are also transmitted together.

In step S2, the monitoring center apparatus 3 receives a car call request. In step S3, the car call command generation unit 26 determines whether or not there is a call in which the building, floor, and moving direction are the same in the car call request received in the predetermined period.

When there are a plurality of calls for a predetermined period, the car call command aggregating unit 27 determines whether or not the aggregation is possible, and aggregates the car call commands in step S5. If there are no plurality of calls, a normal car call command is generated in step S4.

The details of the assembly process of step S5 will be described with reference to a flowchart showing the assembly command generation process of the car call according to an embodiment of the present invention in fig. 6. The car call command aggregation unit 27 stores the obtained plurality of car call commands in the memory 23 in step S20. In step S21, it is determined whether or not the building ID, the call floor, and the movement direction of the car call command match.

When it is determined that the plurality of car call commands match, the plurality of car call commands obtained in step S23 are converted into a single car call command. If it is determined that the commands do not match, the plurality of obtained commands are held in S22. The plurality of commands obtained are not limited to 2, and 3 or more car call commands may be converted into one car call command, but since the number of persons who can take a car is determined for each elevator car, the number of call commands to be converted may be limited by a range smaller than the number of persons who can take a car as a limit.

Returning to fig. 5, it is determined in step S6 whether there are a plurality of elevators available to call to the floor of the building from which the call request was made. Whether a call can be made may be determined based on whether there are a plurality of elevators corresponding to a remote call, or may be determined based on whether there are a plurality of elevators in suspension that are not being serviced.

When there are a plurality of callable elevators, a car call command for the plurality of elevators is generated and issued in step S7, and the issued call command is registered in the car call registration storage 7 in step S8. Then, it is determined in step S9 whether the elevator responding to the call satisfies the condition. The condition may be the earliest responding elevator or an elevator meeting the load corresponding to the number of people called. Also, the response from the cargo elevator or the emergency elevator can be excluded. When the number of elevators to be served and the number of elevators to be served are set according to the time zone, it is possible to determine whether or not the elevator is a response from the elevators that can be served in the time zone.

If the response from the elevator satisfying the condition is provided in step S9, the elevator which does not satisfy the condition or does not respond is obtained from the car call registration storage unit 7 in step S10, and the cancellation command of the car call command is transmitted to the control device.

If there is no response from the control device of the elevator satisfying the condition in step S9, an error message is transmitted to the mobile terminal.

When it is determined in step S6 that there are only 1 elevators capable of calling, a car call command is issued to the control device of the elevator, and the elevator is registered in the car call registration storage unit 7. Even in the case of using 1 elevator, the period of time during which no response to a call from the portable terminal is made can be set by the period of time. Outside such a service period, it is determined in step S13 that the condition is not satisfied, and an error message is output in step S14.

Finally, in step S15, the call history corresponding to the car call command stored in the car call registration storage unit 7 is recorded in the call history storage unit 70, and the car call command stored in the car call registration storage unit 7 is deleted.

Fig. 7 illustrates a car call aggregate command generation process according to an embodiment of the present invention, that is, a case where the car call command 1 (a) and the car call command 2 (b) are car call commands received by the monitoring center device 3 in the same time zone. It is determined whether the building ID, call floor, and moving direction of the car call order 1 and the car call order 2 match. Since the building IDs are identical to "1000", the call floors are identical to "01", and the moving direction is "up", the building IDs can be collected.

Therefore, the car call command 1 and the car call command 2 are aggregated, the building ID, the call floor, and the movement direction are generated as in the car call command of (c), and the destination floor uses both "03" of the car call command 1 and "02" of the car call command 2 as the destination floor car call commands. In order to issue the generated call orders to the elevators a-C capable of calling to the call floor based on the information recorded in the elevator main DB8, 3 orders are generated.

In this example, 2 commands are collected, but 3 or more car call commands may be collected. However, since there is a limit to the car loading amount, it is necessary to estimate the number of persons who get on the elevator by a normal car call without using a portable terminal to collect car call commands.

As a pre-registration process for calling an elevator in the building 1 by a portable terminal operated by a user, (a) a home screen is displayed. The user registers which elevator to call by reading a code such as a two-dimensional code provided at a hall or a medium such as an RFID tag or an IC card through a portable terminal. Among these media are the building ID and elevator ID.

The registration process performs "friend" registration with respect to the building in the same manner as the "friend" registration with respect to other persons by the portable terminal. In this example, it is shown as "thank you registered. XX building "is a building as a registration target, but an elevator or a plurality of elevators installed on floors may be set as a registration unit.

Next, when the user first calls the elevator, the call floor 54 and the destination floor 55 are input from the floor number input screen of (b), and a button such as "call elevator 56" is pressed. By this operation, the call request arrives at the monitoring center apparatus 3, and a call command is transmitted from the monitoring center apparatus 3 to the control panel of each elevator in the building.

When calling the elevator for the second time and later, the user causes the portable terminal to display (c) the floor number input screen. At this time, history buttons 57 and 58, which are a pair of the call floor and the destination floor, are displayed based on the past car call history, and the call floor and the destination floor can be selected from them. Of course, the user may press the select button 59 of another floor and move to (b) the floor number input screen to designate a new call floor or destination floor.

When either one of the button 56 of the calling elevator in the floor input screen (b) or the history buttons 57 and 58 of the floor input screen (c) is pressed, the call start screen (d) is displayed, and when the designation is made by the button, the call is started, and the message "please go from 1 floor to 3 times" of the user corresponding to the calling floor and the destination floor is displayed. In response to the user's request, the elevator displays a "yes-! It is understood that "such a message indicates that the request was accepted. After that, in the case of an elevator that does not respond to a call or in the case of not providing a service for a period of time, etc., a "silent" is displayed as in the (f) result error screen. A message that does not satisfy your expectations.
