As described, it should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention.

1 is a block diagram showing an object floor control apparatus of an elevator according to the present invention.

As shown in the present invention, in the elevator control apparatus, access card 10, card reader 20, access control control unit 30, keypad 50, communication unit 51, the target floor button 52 , A passenger vehicle display unit 60, an elevator controller 70, and a plurality of elevators 80.

The card reader 20 reads the unique identification key stored in the access card 10 and transmits the unique identification key to the communication control unit 51 of the access control control unit 30 and the keypad 50.

Access card 10 is stored with a unique identification key, the card reader 20 may be installed in the doorway.

The access control control unit 30 checks the unique identification key input from the card reader 20 to determine whether access is possible, and inquires the time zone and schedule for access to the corresponding card.

When the passenger carrying the access card 10 arrives at the doorway, the card reader 20 reads the unique identification key stored in the access card 10 without having to input a target floor separately. ) And the communication unit 51.

The keypad 50 is provided for each floor and includes a communication unit 51 and a destination floor button 52.

The communication unit 51 receives the unique identification key and the access data transmitted from the card reader 20 and transmits it to the elevator control unit 70, and the destination floor button 52 is intended to move to the plurality of elevators 80 before boarding. Enter each target floor.

The elevator control unit 70 determines the destination floor by the unique identification key input through the communication unit 51, and also classifies the respective destination floors input by the destination floor button 52 by the same floor and the adjacent floors, thereby allowing the plurality of elevators. Allocate 80 of the most efficient boarding elevators.

The elevator controller 70 may classify the target floors input by the target floor button 52 in addition to the data input from the card reader 20 and classify the same floor and the adjacent floor.

The boarding machine display unit 60 is installed for each elevator gate of each floor, and displays the boarding elevator assigned by the elevator control unit 70.

The destination floor button 52 and the passenger vehicle display unit 60 are not installed inside the elevator 80 but are installed outside. That is, it is preferable to be installed at the positions of the entrance, the entrance, the lobby, etc. of the building and the waiting place for the elevator 80 on each floor.

The target floor inputted through the target floor button 52 of the keypad 50 may be restricted from access to a floor on which access is controlled.

In addition, the elevator control unit 70 preferably allocates another elevator capable of the nearest boarding when the boarding capacity of the assigned boarding elevator is exceeded.

2 is a flowchart illustrating a method for controlling an object floor of an elevator according to the present invention, which can be roughly divided into an access control part and an elevator control part.

The access control unit may include: reading the unique identification key stored in the access card 10 to the card reader 20 and transmitting the unique identification key to the access control control unit 30 and the communication unit 51; The access control control unit 30 checks the unique identification key inputted from the card reader 20 to determine whether access is possible, and controls the access by querying the access time and schedule for the corresponding card. do.

  The elevator control unit determines the target floor by the unique identification key inputted through the communication unit 51 from the elevator control unit 70, classifies each target floor by the same floor and the adjacent floor, and checks the entrance and exit data. Assigning a boarding elevator (80); And displaying the boarding elevator assigned by the elevator control unit 70 on the boarding unit display unit 60.

The card reader 20 reads the unique identification key stored in the access card 10 and transmits it to the communication control unit 51 of the access control control unit 30 and the keypad 50 (S100).

Thereafter, the access control control unit 30 checks the unique identification key input from the card reader 20 and determines whether or not access is possible (S110).

In addition, the access control control unit 30 queries the access time and schedule for the corresponding card, and controls the access state (S120).

On the other hand, in step S100 it is possible to directly enter each destination floor to be moved to the plurality of elevator 80 before boarding with the destination floor button 52. That is, each passenger pre-inputs the destination floor to arrive before boarding the elevator 80.

The elevator control unit 70 determines the target floor by the unique identification key input through the communication unit 51, and classifies the target floor with each target floor directly input by the target floor button 52 by the same floor and the adjacent floor. In addition, the elevator checks the entrance data and allocates the boarding elevator (S130).

The boarding elevator 80 allocated by the elevator control unit 70 is displayed on the boarding unit display unit 60 (S150).

Previously, when it is determined that the boarding capacity of the assigned boarding elevator has been exceeded, the elevator control unit 70 may allocate another elevator that is closest to the boarding elevator to more efficiently distribute and operate the elevator system (S140).

Afterwards, the passengers wait in front of the elevator doorway displayed on the passenger vehicle display unit 60, board the elevator 80, and move to the destination floor without pressing a separate floor button (S160).

That is, the passenger does not use the elevator 80 that arrives first, but boards the elevator 80 allocated to each passenger as indicated on the boarding display 60.

Therefore, since all the elevators are distributed to the adjacent floors, one or more elevators do not stop on the same floor at the same time and the elevator arrives quickly.

3 is a block diagram of a control system representing the preferred embodiment of FIG.

As shown in the present embodiment, the central computer 100, the ACU 110, the I / F board 120, the floor call reader 130, the LCD 140, and the access control controller 150 installed in the gate. And an elevator controller 160.

The present invention is an elevator object floor system integrated with the access control system by applying the access control and automatic floor allocation system to the existing elevator can use the elevator only the floor is allowed or allowed access. You can't go to the floor that you are not allowed to access, and the allowed floor is assigned the fastest elevator when the card reader is recognized at the lobby floor or the reference floor. The elevator destination floor system automatically runs to the desired floor without pressing the floor button. And access control and security systems are one system.

This system is related to the elevator floor system integrated with the access control system installed in a high security building or a general office building where several companies are crowded, and supervisory control for it. It uses NEURON NETWORK and CAN communication technology. IFU (Interface Unit) which communicates with the elevator call reader 130 and the reader 130 and the central computer 100 and the access control controller 150 installed on each floor by applying the elevator object floor system. 120 and the elevator controller 160 to manage the entire target floor.

An elevator visitor registration management system for registering visitors and allocating destination floors is managed by central software stored in the central computer 100.

All networks are equipped with NEURON NETWORK and communicate by bidirectional communication. The entire network belongs to one group and only communicates with the same group while bound to each other. In this state, electrical and physical are one. In other words, IFU (Interface Unit), which is connected to one line and matches network impedance, exists in the middle. The principle of binding is as follows. Nodes that communicate with each other in a network have each other's addresses Nodes send data only to their own addresses. At this time, the number of nodes to be transmitted can be large. In this way, each node shares information and when one event occurs, it shares information about that event. If any event occurs, if the event is not resolved, the node announces the information about the event. Then, other nodes that have information about those events provide the cancellation information for this event and share the results after they are resolved.

In this way, each node becomes neuron-like and smarter as it becomes more information. This technique is used in various functions in the elevator floor. First, a floor allocation requirement arises, and when the button is pressed, it is sent to the central control room while being forwarded to other nodes. In order to transmit information to other places, information must be delivered in order to nodes that should deliver information in the POLLING & RESPONCE method. In order to transmit information to two places, information must be transmitted twice. However, the NEURON method receives information at the same time from other places to which it is bound even if it sends it only once. In other words, the bound nodes receive information together at the same time. The received node transmits a reception completion signal indicating that the information is well received, which is the same as other transmission methods. Because they are used in the same network, data collision occurs like other LAN methods. Each node has a collision detection circuit, so it knows whether the information sent by itself has collided and sends it again if there is a collision. In this case, CDMA is transmitted. CDMA is a typical Ethernet transmission method.

In other words, this is an elevator-oriented system integrated with a state-of-the-art access control system that adopts the NEURON method while the hardware structure has a typical Ethernet structure, and does not require a separate system for further expansion of the system. You can expand the system simply by connecting to.

It is this feature that relates to the LON-WORKS network and its methods for monitoring emergency situations in multiple locations simultaneously.

The elevator target floor system can be operated in security mode and normal mode, and the general mode is a mode that does not use a security system, when there is a need to unsecure an elevator in a building or when a tenant moves or moves in an office building. Used when you need to temporarily disable security.

In security mode, all users must have a card to use the elevator. A user who does not have a card cannot use the elevator. This is because the reader using the target floor does not have an input button inside the elevator for entering the floor.

However, when the normal mode is set, the floor call button on the reference floor may use the elevator by using the floor call button 130 on each floor. However, in this case, you cannot enter the layers you want to go. In other words, if you enter the 12th floor from the 1st floor, you cannot get off in the middle, but you have to enter the floor you want to get off the 12th floor and go back. In conclusion, in normal mode, it can be used like a normal elevator, but there is no floor button inside the elevator.

In the security mode, in addition to the access card, the biometric authentication system (not shown: fingerprint recognition, eyeball, face recognition, etc.) must be recognized to identify the user and input the desired floor. When a person authenticated by a card or bio-certification system enters the desired floor, the reader scans the internal memory, and if it is not in memory, the IFU (Interface Unit) searches the floor information for that person to determine if the floor is acceptable. If it is checked and the floor is acceptable, then again it is searched for acceptable time zones and signals the elevator central processing system that the elevator can be used if all of the conditions are acceptable. The elevator central processing system receiving the permission signal allocates the elevator to the floor input by the user and moves to the input floor when the user boards the elevator.

In security mode, the elevator destination floor allocation system, which is part of the access control system, determines whether the elevator user can use the elevator and can go to the floor to which he or she is going and whether it is time to go, and sends the determined information to the elevator central processing system. The system for assigning the elevator and operating the elevator is made in the elevator's own system.

The security floor is different from the security mode. The security floor decides whether to put the floor in security mode or in normal mode. All elevator floor systems must be in security mode. In other words, the security floor can be set when all layers are in security mode. Security floors are used when some floors require security and some do not require security, such as an interview room. The floor set as a security floor is operated by a card or bio authentication system, but the floor without security floor can be used without a card or bio authentication. That is, floors that are not security pros can use elevators without card information or bio information.

However, if you want to go to the floor designated as a security floor, you must use a card or biometric system to get the elevator destination system certified.

The elevator destination floor system first detects whether the floor is a secure floor when the floor information comes in, and sends the floor information to the elevator central processing system if it is not a secure floor. Information should only be sent to the elevator central processing system.

In general, it is easy to confuse security mode with the security floor, which is an algorithm that determines whether or not to use a security system, and the security floor is an operating algorithm within an algorithm that uses a security system. When the security mode is set to the normal mode, it operates as an elevator system that is separate from the security system, and when set to the security mode, all decision authority to go to the floor is moved by the security system.

Floors that are not set up as security floors are also controlled by the elevator destination floor system, but allow use without checking the elevator user's authority.

When a layer without security mode is generated, a security incident occurs that goes to the security layer without the security mode. Therefore, setting and disabling the security mode is applied to the entire system at the same time.

If you try to turn off Secured Mode and there is only one layer on the floor, you must have an authorized signature from the super administrator (admin account) to release it.

When security mode is turned off, the entire security layer is lost.

The practical application of the target layer implementation technology is described as follows.

The card reader or bio reader has up to 128 layers of information on the security floor in bits. The 128 layers are organized in bits and consist of 16 bytes. Each bit represents one layer, and if it is set to security floor, it is set to 1 value and set to 0 value. These 16 bytes are gathered and expressed as HEX values, which transmit and receive information to the central destination program.

The security floor is the information that the card reader or bio reader has on each floor.

User information includes ID number or personal information key value on the card reader or bio reader, and information about the floor to which the user can go. Layer consists of 1 bit.

That means you can go up to 128 floors. One user information consists of 16 bytes of card ID information and 2 bytes of reference layer available, and 8 bytes of available time of 16 bytes of floor information.

If the reference layer is zero and the usable layer is zero, there is no layer to go, so it is rejected. The reference floor refers to the floor mainly used by the user and the working floor.

The distinction between visit card and commuter card or employee card is not commuter pass or employee card. There is no personal information in the card's internal memory. It recognizes the unique ID of the card and retrieves the recognized card number from the reader memory. The leader has the personal information transmitted from the central control system.

The visitor's card has a separate visitor's card and the visitor's information and the authorized floor are entered. You can only go to one floor of the visit card, and if you go to another floor, you will need to reissue it.

In the visit card, the floor information is input as one byte into the memory inside the card.

In the case of a visitor's card, the card memory contains the floor information that the card is going to go to, and transmits the floor to the elevator central processing system. The transferred elevator will assign the elevator to the visitor.

In addition, the elevator object floor system is provided with as many input and output devices as necessary to be able to interlock with the fire fighting system. In the event of a fire or emergency, the elevators are released from the security mode, except for critical security, so that all elevators return to manual mode while operating in the elevator's own fire mode.
