Description

Elevator control method and elevator control system

Technical Field

The present invention relates to a control system for an elevator.

Background

Conventionally, a plurality of elevators are installed in buildings, facilities, and other buildings, and users use a car that has reached a landing where the users get in the car. In such elevators, it is necessary to call an elevator to a landing. 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 installed in the hall, which transmits a wireless signal to the hall of any floor, starts application software for call registration installed in advance in the portable terminal, and transmits a preset target floor of the user to the elevator control device by starting the application software of the portable terminal. An elevator system is disclosed in which an elevator control device registers a user's destination floor as a hall call and a car responds to the registered floor of the hall call.

Here, in patent document 1, when call registration is performed by a portable terminal for a plurality of elevators, a group management control device of the elevators selects a car that can respond to a call and responds to the call from the portable 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 installed in a building, all cars are called. Therefore, when an elevator without a group management function is installed, a new group management control device needs to be installed. Even when the group management control device has a group management function, a car selection function for selecting a car needs to be added to the group management control device.

Detailed Description

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, it is assumed that the user wants to use any one of the elevators a 16 to C18 installed in the building 1. In addition, the building 1 performs 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 apparatus 3 may be configured to manage a plurality of elevators divided into groups, for example. The number of elevators is not limited to 3 as shown in fig. 1, and may be 1 or more.

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

Here, the portable terminals 19 and 20 are held by respective users, and remote call request applications for calling elevators are installed. The mobile terminals 19 and 20 can be realized by an information processing device such as a mobile terminal such as a smartphone, a tablet PC, a mobile phone, or a notebook PC. The mobile terminals 19 and 20 may be implemented by smart devices connectable to smartphones or the like. In fig. 1, 2 mobile terminals 19 and 20 are shown, but the number is not limited to this. The portable terminals 19 and 20 described later may be used by each user outside the building 1.

The monitoring center device 3 is provided in the monitoring center 2 and includes a data transmission/reception unit 5, an elevator control unit 6, a call registration storage unit 7, and an elevator master DB 8. The data transceiver 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 calls the elevator using the car call command 28 received by the data transceiver 5, that is, generates a car call command for controlling the operation 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 implemented 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 master DB8 is preferably implemented by a storage device called a so-called storage device or the like. The elevator master DB8 may be configured by a housing different from the monitoring center device 3. In this case, the elevator master 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 (monitoring device a10, monitoring device B11, and monitoring device C12) for managing these 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 16, elevator B17, and elevator C18), but may have a function of remotely controlling the elevators in accordance with a command from a monitoring center device. The control device is also called a control panel, and is provided in the lifting path, the machine room, and the like.

The monitoring terminal 4 is connected to the monitoring center apparatus 3 via a public network 90. The monitoring terminal 4 can be implemented by a computer device, and can transmit an instruction to the monitoring center apparatus 3 and output the processing content of the monitoring center apparatus 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 installed in the monitoring center 2 or may be used outside.

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 is configured to connect a network I/F2100 (network interface) 21, a processing unit 22, a memory 23, a 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, and uses NFC (Network Interface Card) or the like for connection and communication with the outside such as the public Network 90.

The Processing Unit 22 is a Processing device such as a CPU (Central Processing Unit), and executes software modules stored in the memory 23 by referring 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 integration unit 27.

The car call command generating unit 26 generates a car call command 28 based on a car call request from a user by referring to the elevator master information 30 stored in the storage device 24. At this time, the car call command integrating unit 27 integrates, as one car call command, car call commands that can be integrated into one car call command among car call requests from a plurality of users received within a certain period of time.

When the car call command generated by the car call command generation unit 26 is issued to the control devices 13 to 15 via the monitoring devices 10 to 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 a call history from the user. The history is not stored in its entirety, but is recorded for a predetermined period or the number of times. The history can be used to preset the user's call floor and destination floor.

The storage device 24 can be realized by an HDD (Hard Disk Drive), an SSD (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 the elevator master information 30 used in the present embodiment. The elevator master information 30 is information in which a building ID for identifying the building 1 is associated with an elevator ID that is elevator identification information for identifying an elevator installed in the building 1.

In fig. 3, the elevator master 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 as 1 record, and a plurality of elevator IDs may be included in the 1 record. As described above, the building ID is an example for identifying a 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 in which the control request ID41, the call floor 42, the destination floor 43, the building ID44, and the elevator ID45 are associated with one another. Control request ID41 is used to identify a car call request from a user. The call floor 42 represents the floor at which the user wishes to board the elevator at the landing. The destination floor 43 represents the floor where the user gets off the elevator. The names of the call floor and the target floor are not limited to the expressions of the hall floor and the target floor.

The building ID44 and the elevator ID45 are determined with reference to the elevator master information 30.

Fig. 5 is a flowchart showing an example of car call processing according to an embodiment of the present invention. The user of the elevators 16-18 provided in the building 1 sets the elevator to be used in the application installed in the portable terminal 19-20. Specifically, the portable terminals 19 to 20 read identifiers such as two-dimensional barcodes installed in landings. In this case, a specific elevator may be set, or a plurality of elevators provided in the building may be set in a group.

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 a mobile terminal) generates a car call request and transmits the car call request to the monitoring center apparatus 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 generating unit 26 determines whether or not there is a call in the same building, floor, and moving direction in the car call request received in a predetermined period.

When there are a plurality of calls for a predetermined period, the car call order integrating unit 27 determines whether integration is possible, and integrates the car call orders in step S5. If there are no plurality of calls, a normal car call command is generated in step S4.

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

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

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

When there are a plurality of elevators available for calling, car call commands for the plurality of elevators are generated and issued in step S7, and the issued call commands are registered in the car call registration storage unit 7 in step S8. Then, in step S9, it is determined whether or not the elevator that responded to the call satisfies the condition. The condition may be the elevator that responds earliest or the elevator that satisfies the load corresponding to the number of people called. Further, the response from the freight elevator and the emergency elevator can be excluded. When the number of elevators providing service and the number of elevators are set according to the time zone, it is possible to determine whether or not the elevator is a response from an elevator that can provide service in the time zone.

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

If there is no response from the elevator control device that satisfies the condition in step S9, an error message is sent to the portable terminal.

If it is determined in step S6 that the number of elevators capable of calling is only 1, 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, it is possible to set a time period in which no response is made to a call from a portable terminal by the time period. 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 is a diagram illustrating an aggregate command generation process of car calls 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 apparatus 3 in the same time zone. It is determined whether or not the building ID, call floor, and moving direction of the car call command 1 and the car call command 2 match. The building IDs are equal to "1000", the call floors are equal to "01", and the moving direction is "up", and therefore, they can be collected.

Therefore, the car call command 1 and the car call command 2 are combined, and like the car call command of (c), a car call command is generated in which the building ID, the call floor, and the moving direction are the same, and the target floor includes both the "03" of the car call command 1 and the "02" of the car call command 2 as the target floor. In order to issue the generated call command to the elevator a-C that can call to the call floor based on the information described in the elevator master DB8, 3 commands are generated.

In this example, 2 commands are collected, but more than 3 car call commands may be collected. However, since there is a limit to the car load, it is necessary to collect the car call command by predicting the number of people who get on the elevator by a normal car call without using the portable terminal.

As a preliminary registration process for calling an elevator in the building 1 by a portable terminal operated by a user, (a) a main screen is displayed. A user registers which elevator is called by reading a code such as a two-dimensional code or a medium such as an RFID tag or an IC card provided in a hall with a mobile terminal. Among these media are building ID and elevator ID.

This registration process performs "friend" registration for the building in the same manner as the portable terminal performs "friend" registration for other people. In this example, the display is "thank you friends registration. XX building "is a building to be registered, but an elevator or a plurality of elevators installed on floors may be set as a registration unit.

Next, when the user calls the elevator for the first time, the user inputs the call floor 54 and the destination floor 55 from the floor number input screen (b), and presses a button such as "call elevator 56". By this operation, a call request arrives at the monitoring center device 3, and a call command is transmitted from the monitoring center device 3 to the control panels of the individual elevators in the building.

When calling the elevator for the second time or later, the user causes the portable terminal to display (c) a floor number input screen. At this time,

history buttons

57 and 58 having a pair of a call floor and a target floor are displayed based on past car call history, and the call floor and the target floor can be selected from among them. Of course, the selection button 59 of another floor may be pressed to move to the floor number input screen (b) to specify a new call floor and a new destination floor.

When any one of the button 56 for calling the elevator in the (b) floor input screen and the

history buttons

57 and 58 in the (c) floor input screen is pressed, the (d) call start screen is displayed, the call is started when the button is designated, and the message "please from 1 floor to 3 times" of the user corresponding to the call floor and the target floor is displayed. In response to the user's request, the elevator displays "yes! It is understood that such a message indicates acceptance of the request. Then, if there is no elevator responding to the call or the service providing time slot is not in use, the "wrong answer" is displayed as in the (f) result error screen. A message that does not satisfy your expectation.
