Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly to an elevator control device used in a security system in a building.

[0002]

2. Description of the Related Art In recent years, a security system in a building has come to be regarded as important, a floor with a computer room, a floor with a room for executives of a company, and
At night, a system that allows elevators to access the floors, etc. after all tenant employees have left the company is in operation.

A conventional system of an elevator control device of this type will be described. FIG. 6 is a system configuration diagram showing a conventional elevator control device. It should be noted that although three elevators are shown in the figure, the actual number of elevators installed is in each building.

In the figure, 1 to 3 are well-known card readers arranged in respective elevator cars, each having its own data transmission path. 4 is each card reader 1
3 is a security system controller to which data is transmitted. However, a cable that connects the elevator car and the control device may be used as the physical transmission path. However, the security system controller 4, which normally has its own control line for data transmission, may be connected to an external device such as a building management device. Reference numeral 5 is an elevator group managing means for group managing the respective elevator cars. In this system, the security system controller 4 is capable of data transmission with the elevator group managing means 5. Elevator control units 6 to 8 control the operation of each elevator, and perform various controls such as opening and closing doors and moving between floors. The elevator group management means 5 is connected to each of the elevator control means 6 to 8 and performs hall call assignment and other various controls.

Here, the simple operation of the elevator control means 6 to 8 will be described. FIG. 7 is a flowchart showing the operation of the elevator control means of the conventional elevator control device.

In the figure, it is judged in step S1 whether or not there is a car call or an assigned hall call. If it is judged that there is a car call, in step S2, the nearest destination floor is selected in consideration of the car operating direction. After determining, the vehicle travels to the destination floor in step S3. Then, in step S4, open the door,
Open the door for a predetermined time in step S5
The door is closed at 6 and the process returns to step S1 again.

In order to register a car call to a floor in which normal car call registration is not permitted by a person having a predetermined qualification, such as a floor with a computer room, in an elevator under such control, Insert a predetermined card into the card readers 1 to 3 in the elevator car, perform a recitation number and other predetermined operations, and then press the car call button on the predetermined floor to register the car call. In addition, recently, there are some which use a non-contact card, so that card operation may not be necessary in some cases. In this case, the data flow in the system is as shown in FIG.

FIG. 8 is a block diagram showing the flow of data transmission in the system of the elevator control device.

As shown in the figure, first, the card reader reads the ID information in the card and transmits it to the security system controller. The security system controller determines the qualifications of the cardholder and commands the elevator group management means by transmission to authorize service to a given floor of a given elevator car. The elevator group management means transmits a car call registration permission signal of a predetermined floor to the elevator control means of the predetermined car. Upon receiving the signal, the elevator control means registers the car call in response to the pressing of the car call button.

[0010]

In the conventional elevator control device as described above, it takes time because data is transmitted through a plurality of controllers. For this reason, the state of the elevator car changes before the car call registration permission reaches the elevator control means, and another operation (for example, the operation direction is changed to move to respond to another hall call) is performed. There was something.

Further, when the card reader and the elevator control means perform the transmission directly, since a large amount of data transmission is required between the security system controller and the elevator, a program for a dedicated communication line is required. It required a lot of expenses such as the development and the addition of hardware.

Therefore, according to the present invention, the existing inexpensive data transmission path allows the elevator to temporarily hold a predetermined state and not start the next operation until the data transmission from the card reader is completed. It is an object of the present invention to provide a control device.

[0013]

According to a first aspect of the present invention, there is provided an elevator control device, a card reader disposed in an elevator car, a state determination means for determining a state signal of the card reader, and the state. State holding means for holding the elevator in a predetermined state according to the determination made by the determination means.

According to a second aspect of the present invention, there is provided an elevator controller according to a card reader arranged in an elevator car, a state discriminating means for discriminating a state signal of the card reader, and a discriminant by the state discriminating means. The state holding means for holding the elevator in the door closed state, and the state switching means for performing a dedicated operation according to the operation of the card reader while the elevator is held in the door closed state.

[0015]

In the elevator controller according to the first aspect of the present invention, the status signal of the card reader disposed in the elevator car is discriminated, and the elevator is in the predetermined status while the status signal of the card reader is in the predetermined status. The state of the elevator is temporarily retained during the data transmission from the card reader, and the state of the elevator is not changed during this period so that another operation is not performed.

In the elevator control device according to the second aspect of the present invention, the status signal of the card reader installed in the elevator car is discriminated, and the elevator door is closed while the status signal of the card reader is in a predetermined state. Since it is to be held for a while and dedicated operation is performed during that time, the elevator car is in the door closed state during data transmission from the card reader,
It is possible to realize a desired dedicated operation according to the operation of the card reader without another passenger getting into the elevator car.
