RSI based elevator control system

The present invention relates to an RSSI-based elevator control system, and more particularly, receives a signal from a user terminal, measures a Received Signal Strength Indication (RSSI) value, and enters a power saving mode or a power saving mode based on the measured RSSI value. The elevator is controlled to release the elevator so that when there is no elevator user, the elevator enters power saving mode immediately without unnecessary waiting time. It relates to an RSSI-based elevator control system capable of effective energy saving by enabling it to determine who is expected to use the elevator even in one state.

BACKGROUND ART In general, an elevator is a major transportation means for transporting passengers to a predetermined floor of a building using an elevator car that moves up and down along a hoistway, and is an essential device in a modern society where high-rise buildings are lined up.

Various studies have been conducted to move passengers more efficiently and safely from the introduction of these elevators to the present. .

As a conventional representative method for saving energy in the elevator, a method of switching to a standby mode when there is no user of the elevator, and canceling the standby mode when a request for use of the elevator occurs, is used.

Looking at the conventional elevator energy saving method in more detail, when a certain period of time elapses in a state where the car of the elevator does not operate and no additional calls are made on each platform floor, the elevator enters the standby mode to to stop the operation. And when a call button is input on one platform floor while entering the standby mode and a call occurs, the standby mode is immediately terminated, so that the lights and fans inside the platform operate, and the elevator car moves to the called floor.

As such, the conventional elevator energy saving method cannot cut off the power line supplying power to the call button and the input sensing unit in the standby mode because the passenger's call button input must be detected even in the standby mode, and the power line connected to the light and the fan There is a problem in that the actual power deduction effect of the elevator is not large because the standby power cannot be cut off by limiting the block.

1 is a block diagram schematically illustrating an RSSI-based elevator control system according to an embodiment of the present invention, and FIG. 2 is a receiving device 100 and a control device 200 according to an embodiment of the present invention. It is a block diagram illustrating the configuration of , and FIG. 3 is a diagram illustrating a process in which the operation control unit 210 controls the elevator to release the standby mode according to an embodiment of the present invention. And FIG. 4 is a diagram illustrating a process of operating the elevator so that the operation control unit 210 enters the standby mode according to an embodiment of the present invention.

1 to 4, the RSSI-based elevator control system (hereinafter referred to as 'control system') according to the present embodiment receives a signal from a user terminal (UD) possessed by a user and a user terminal (UD). A receiver 100 for measuring a Received Signal Strength Indication (RSSI) value, and a control device for operating and controlling the elevator to enter or release the power saving mode based on the RSSI value measured by the receiving device 100 (200). Here, the user terminal may be a device capable of transmitting a wireless signal by operating Bluetooth or WIFI such as a smart phone and various wearable devices.

At this time, the reception device 100 is disposed on the platform of each floor and receives a signal from the user terminal to measure the Hall RSSI value, and the reception device 100 is disposed in the car (C) of the elevator and the user terminal (UD). and a car signal receiver 130 for receiving a signal from and measuring a car RSSI value. And the control device 200 is a driving control unit that controls the operation of the elevator to release the power saving mode when there is a value above the threshold value among the measured Hall RSSI value and the car RSSI value, and to enter the power saving mode when there is no value above the threshold value. 210 may be included.

Specifically, referring to FIGS. 3A and 3B , the hall signal receiver 110 and the car signal receiver 130 of each floor receive a signal transmitted from the user terminal UD and measure the RSSI value. And when the user approaches the elevator platform to use the elevator, the strength of the signal received from the user terminal (UD) carried by the user increases, so that the RSSI value measured by the hall signal receiver 110 and the car signal receiver 130 also increases. do. At this time, the receiver having the largest RSSI value received from the user terminal UD due to the arrangement position of each Hall signal receiver 110 and the car signal receiver 130 is the Hall signal receiver 110 of the floor where the user terminal UD is located. ) becomes

If, as shown in FIG. 3b , the user terminal UD is located within a certain distance from the elevator platform, and the hall RSSI from the user terminal UD is greater than or equal to the threshold in the hall signal receiver 110 of the floor where the user terminal UD is located. When the value is measured, the operation control unit 210 may control the operation of the elevator so that the power saving mode of the elevator is released. Of course, if the elevator is not in the power saving mode, it should be maintained.

And, on the contrary, as shown in FIGS. 4a and b, the user with the user terminal (UD) gets off the car after using the elevator and moves away from the platform by a certain distance, so that the hall signal receiver 110 and the car signal receiver on each floor ( When all the RSSI values measured in 130) are less than the threshold value, the operation control unit 210 may control the operation of the elevator so that the elevator enters the power saving mode. Here, the signal receiver from which the RSSI value less than the threshold value is measured last may be the hall signal receiver 110 disposed in the platform of the floor where the user gets off.

At this time, the operation control unit 210 operates and controls the elevator to enter the power saving mode immediately without waiting time if there is no value equal to or greater than the threshold value among the measured Hall RSSI value and the car RSSI value, and when entering the power saving mode, the elevator moves inside the car The light (L) of the car, the fan inside the car, the elevator call button, the target floor selection button and the car door opening and closing button inside the car, and the power supply to the display device that outputs the floor information and operation status information of the car are cut off, Conversely, when the power saving mode is released, the power supply that was cut off may be resumed.

And, if the Hall RSSI value measured by the Hall signal receiver 110 is equal to or greater than the threshold, the control device 200 according to the present embodiment boards the floor on which the Hall signal receiver 110 in which the Hall RSSI value equal to or greater than the threshold is measured is disposed. It may further include a boarding request determination unit 220 that determines that the requester has occurred.

At this time, the boarding request determination unit 220 is configured to, if a hole RSSI value equal to or greater than a threshold value is measured from the same user terminal (UD) in the plurality of hall signal receivers 110, the hall signal receiver ( It can be determined that the boarding requester has occurred on the floor where 110) is arranged. In addition, the boarding request determination unit 220 is a Hall signal receiver in which the Hall RSSI value equal to or greater than the threshold value is measured first when the Hall RSSI value equal to or greater than the threshold is measured from the same user terminal UD in the plurality of Hall signal receivers 110 . It may be determined that the boarding requester has occurred on the floor where 110 is disposed.

Here, the threshold value of the RSSI value serving as the criterion for the determination of the driving control unit 210 for canceling the power saving mode and the threshold value of the RSSI value serving as the criterion for determining the occurrence of the boarding requester in the boarding request determination unit 220 are the same In this case, when it is determined by the boarding request determination unit 220 that a boarding requester has occurred, the operation control unit 210 may control the operation of the elevator so that the power saving mode of the elevator is released.

In addition, when the boarding request determination unit 220 determines that the boarding requester has occurred, the operation control unit 210 may operate and control the elevator so that the car C is called to the floor where the boarding requester occurred.

That is, when a user carrying a user terminal (UD) approaches within a certain distance from the platform, the hall signal receiver 110 disposed on the corresponding floor measures a hole RSSI value greater than or equal to the threshold, and a hole RSSI value greater than or equal to the threshold value is measured. Simultaneously with this measurement, the operation control unit 210 releases the power saving mode of the elevator, and the boarding request determination unit 220 determines the floor where the user terminal UD is located and determines that a boarding requester has occurred on the corresponding floor, and the operation control unit 210 may control the operation of the elevator to call the elevator car (C) on the floor where the boarding requester is generated. Accordingly, the control system according to the present embodiment can effectively save energy.

The control device 200 according to the present embodiment includes a ride determining unit 230 that compares the hole RSSI value and the car RSSI value to determine whether a user who has a user terminal (UD) rides, and the hole RSSI value and the car RSSI value. The method may further include an alighting determination unit 240 that compares the values to determine whether the user carrying the user terminal UD gets off.

Specifically, the riding determination unit 230 compares the largest value among the hall RSSI values measured by each hall signal receiver 110 with the car RSSI value. , and the alight determining unit 240 compares the largest value among the hall RSSI values measured by each hall signal receiver 110 with the car RSSI value. It can be considered as leaving

At this time, the distance from the hall signal receiver 110 to the car door on the floor where the elevator car C is stopped on one floor and the distance from the car signal receiver 130 to the car door are the same for each hall The signal receiver 110 and the car signal receiver 130 may be respectively disposed to be positioned. By making a point where the distance from the user terminal UD to the hall signal receiver 110 of the stopped floor and the distance to the car signal receiver 130 the same as the car door position, the user terminal UD is located inside the car This is so that the car RSSI value becomes larger if it is, and the hole RSSI value becomes larger when the user terminal (UD) is located outside the car.

And at this time, the operation control unit 210 compares the largest value among the hall RSSI values measured by each hall signal receiver 110 with the car RSSI value so that the elevator car door is not closed when the difference between the two values is within a set range. You can control the operation of the elevator. This is to prevent the user from getting caught in the door when the difference between the two RSSI values is within the set range because there is a high possibility that the user is located at the car door or is very close.

On the other hand, the control device 200 identifies the user terminal (UD) based on the user information included in the signal received from the hall signal receiver or the car signal receiver, and a terminal identification unit for determining whether to pre-register the identified user terminal. Further including 260, the operation control unit 210, the boarding request determination unit 220, the boarding determination unit 230, and the getting off determination unit 240 target the RSSI value of the pre-registered user terminal (UD). It can only perform judgment and control.

That is, the control device 200 according to the present embodiment processes only the hole RSSI value and the car RSSI value of the corresponding signal as valid values only when the signal received by the receiving device is a signal of a previously registered user terminal (UD). . Therefore, even if a user with an unregistered user terminal (UD) approaches the elevator platform, the operation control unit 210 does not release the power saving mode of the elevator, and the boarding request determination unit 220 does not determine the occurrence of occupants. .

The operation control unit 210 according to the present embodiment is configured to automatically input the target floor based on the user information registered in the user terminal (UD) when the ride determination unit 230 determines that the user has boarded the car (C). You can control the operation of the elevator.

Specifically, the operation control unit 210 automatically inputs the designated residential floor as the target floor during pre-registration of the user terminal (UD) if the floor the user boarded is the lobby floor, and targets the lobby floor if the floor the user boarded is the residential floor The elevator can be operated and controlled to automatically enter the floor.

For this reason, the control system according to the present embodiment has an effect of providing high convenience by automatically calling a car and selecting a target floor without the user inputting a call button or a target floor button. In addition, by allowing the elevator to operate only for pre-registered users, there is an effect that the security of the building or residents can be strengthened.

The operation control unit 210 according to this embodiment controls the elevator to cancel the manually input target floor if the lobby floor or residential floor is not canceled within a threshold time when the target floor other than the lobby floor or the residential floor is manually input. You can control driving.

That is, when a user with a pre-registered user terminal (UD) boards the elevator car (C) on the lobby floor, the residential floor is automatically entered and the car (C) is operated toward the residential floor. However, when the user's target floor is a floor other than the residential floor, the user can set the other floor as the target floor only when the user presses a button corresponding to the residential floor to cancel the residential floor from the target floor. This is to prevent a user who does not have a pre-registered user terminal (UD) from using the elevator together when a user with a pre-registered user terminal (UD) uses the elevator. In addition, when the user with the user terminal (UD) cancels the automatically selected target floor and selects another floor as the target floor, the user can further enhance security by recording this and sending it to an external server.

The control device according to the present embodiment further includes a boarding state determination unit 250 that determines whether or not the user is boarded in the car while the car C is moving, and the operation control unit 210 includes the boarding status determination unit 250 . When it is determined that the user does not board the elevator, the elevator may be operated and controlled to cancel the automatically entered target floor. This is to prevent unnecessary energy consumption due to misjudgment by erroneously judging that the user has boarded by the ride determination unit 230 and stopping the operation by immediately determining that the user is not riding even if the elevator car C is operated to the automatically set target floor. and to minimize the user's waiting time for the elevator car (C) due to misjudgment.

Looking more specifically at how the boarding status determination unit 250 determines whether a user is in the car while the car C is moving, first, the boarding status determination unit 250 provides a hall signal receiver ( 110), when the measured hole RSSI value sequentially increases and then decreases, it may be determined that the user has boarded.

If the user terminal (UD) is located inside the elevator car (C) and the elevator is operating upward, the hall RSSI values measured in the order of the hall signal receivers 110 disposed on the second, third, and fourth floors are It increases and decreases from the time it passes through each floor, and if the elevator is running downward, the hall RSSI value increases in the reverse order and decreases from the time it passes through each floor.

Also, the boarding state determination unit 250 may determine that the user has boarded when the change width of the car RSSI value is less than the reference width. If the user terminal (UD) is located outside the car (C) and the car (C) is operated upward, the car RSSI value will decrease significantly without running for a while.

5 is a flowchart schematically illustrating an RSSI-based elevator control process according to an embodiment of the present invention.

Referring schematically to the RSSI-based elevator control process according to the present embodiment with reference to FIG. 5 , first, the boarding request determination unit 220 may determine whether a boarding requester has occurred ( S100 ). If the boarding requester does not occur (S100-N), it waits until the boarding requester occurs, and when the boarding requester occurs (S100-Y), the operation control unit 210 determines whether the elevator is in power saving mode (S200), In the case of the power saving mode (S200-Y), the power saving mode is released (S250), and if not in the power saving mode (S200-N), the process of canceling the power saving mode is omitted.

And after the power saving mode is released or this process is omitted, the operation control unit 210 may operate and control the elevator so that the car C is called to the floor where the generation of the boarding requester is detected (S300).

When the elevator car C arrives at the called floor and the door of the car is opened, the ride determination unit 230 determines whether the user has boarded (S400). If the user does not get on (S400-N), the operation control unit 210 determines whether the threshold time has elapsed (S450), and if the threshold time has not elapsed (S450-N), the threshold time determines whether the user rides again. It is determined (S400), but if the threshold time has elapsed (S450-Y), it is determined whether all the RSSI values measured by the hall signal receiver 110 and the car signal receiver 130 are all less than the threshold value (S800), and all the RSSI When the value is less than the threshold value (S800-N), the operation control unit 210 controls the elevator to enter the power saving mode (S900), and the RSSI-based elevator control process ends.

If there is an RSSI value equal to or greater than the threshold value (S800-N), it is determined whether the threshold time has elapsed (S850), and if the threshold time has not elapsed (S850-N), it is determined again whether the RSSI value is less than the threshold value (S800), when the threshold time has elapsed (S850-Y), the operation control unit 210 controls the elevator to enter the power saving mode (S900), and the RSSI-based elevator control process ends.

On the other hand, if the user rides in the elevator car (C) (S400-Y), the operation control unit 210 controls the operation of the elevator so that the car (C) is operated (S500), and the boarding state determination unit 250 is the car ( When the operation of C) starts, it may be determined whether the user is driving in the riding state (S600).

If it is determined that the user is driving in the boarding state (S600-Y), the vehicle continues to operate, and when the car C arrives at the target floor, the alighting determination unit 240 may determine whether the user has alighted (S700). ). And if it is determined that the user does not get off (S700-N), it waits until the user gets off, and if it is determined that the user has got off (S700-Y), all RSSI values are less than the threshold value to enter the power saving mode It is determined whether it is (S800).

And when it is determined that the user does not board during operation (S600-N), the operation control unit 210 controls the operation so that the elevator operation is immediately stopped, and returns to the beginning again to determine whether a boarding requester has occurred (S100) .

6 is a flowchart illustrating in more detail a process of determining a boarding requester during an RSSI-based elevator control process according to an embodiment of the present invention.

Referring to FIG. 6 , in the RSSI-based elevator control process according to the present embodiment, the boarding requester determination process will be described in more detail. First, it is determined that the signal of the user terminal (UD) registered by the terminal identification unit 260 has been received. If it is (S110), the boarding request determination unit 220 may determine whether the measured hole RSSI value of the user terminal signal exceeds a threshold value (S120). If the threshold is exceeded (S120-Y), the boarding request determination unit 220 may determine that the boarding requester has occurred on the corresponding floor (S130), and if it does not exceed the threshold (S120-N), boarding It may be determined that the requester has not occurred (S140).

7 is a flowchart illustrating in more detail a user boarding decision process among the RSSI-based elevator control process according to an embodiment of the present invention.

Referring to FIG. 7 , in the RSSI-based elevator control process according to the present embodiment, the user boarding determination process will be described in more detail. First, when the car stops at the called floor (S410), the boarding determination unit 230 is the largest hall. It may be determined whether the RSSI value is smaller than the car RSSI value (S420).

In addition, when the largest hole RSSI value is smaller than the car RSSI value (S420-Y), the ride determining unit 230 determines that the user has boarded the car (C) (S430), and the largest hole RSSI value is the car RSSI value (S430). If it is not smaller than (S420-N), it may be determined that the user does not ride the car (C) (S440).

8 is a flowchart illustrating a car operation process in more detail among the RSSI-based elevator control process according to an embodiment of the present invention.

Referring to FIG. 8 , among the RSSI-based elevator control process according to the present embodiment, the car operation process will be described in more detail. First, the operation control unit 210 controls the boarding floor based on the registered user information of the user terminal UD. It may be determined whether the user's residential floor is (510).

If the riding floor is the user's residential floor (510-Y), the operation control unit 210 controls the operation so that the lobby floor is input as the destination floor (520), and when the riding floor is not the user's residential floor (510-N) ), the operation control unit 210 may control the operation so that the residential floor is input as the destination floor ( 530 ).

When the destination floor is input, the operation control unit 210 may determine whether a floor other than the lobby floor and the pre-registered residential floor has been input as the destination floor ( 540 ). If the other floor is not entered as the destination floor (540-N), the elevator car (C) is operated to operate to the destination floor (S570), and when the other floor is input as the destination floor (540-Y), the lobby It may be determined whether the input of the destination floor of the floor or residential floor is canceled ( 550 ).

If it is canceled (550-Y), the operation control unit 210 controls the operation so that the car C is operated to the changed destination floor (570), but if it is not canceled (550-N), the additionally inputted other floor cancels the input of the destination floor (560), and may control the operation of the car (C) so that the existing destination floor, the lobby floor, or the registered residential floor, is used as the destination floor (570).

9 is a flowchart illustrating in more detail a process of determining whether a user is operating in a boarding state during an RSSI-based elevator control process according to an embodiment of the present invention.

Referring to FIG. 9 , a process of determining whether a user is operating in a boarded state during the RSSI-based elevator control process according to the present embodiment will be described in more detail. First, the boarding status determination unit 250 determines a change in the measured car RSSI value. It is determined whether the width is within the reference width (S610), and when it is out of the reference width (S610-N), it may be determined that the user is driving the car in a non-riding state (S640).

If the change width of the car RSSI value is less than the reference width (S610-Y), the boarding state determination unit 250 sequentially increases and decreases the hall RSSI value measured from the hall signal receiver 110 of each floor in the order of rise and fall. It can be determined whether there is a change (S620).

And when the boarding state determination unit 250 sequentially changes (S620-Y), it is determined that the car (C) is moving in the user's boarding ecology (S630), but does not change sequentially (S620-N) ), it may be determined that the car C is moving in a state in which the user is not riding (S640).
