A hall operation panel 5 provided on each floor has a hall call switch 6 for calling a car and a hall door closing switch 8 for closing a car door. Reference numeral 11 denotes an operation control unit for controlling the operation of the car by receiving signals from the car call switch 2 and the hall call switch 6 while inputting a car position signal or the like through the signal input circuit 10. Reference numeral 9 denotes a car call switch 2, a car door open switch 3, a hall call switch 6, when a door opening / closing permission signal 19 is input from the operation control unit 11.
The door drive circuit 14 receives the signal from the hall door close switch 8.
The door control unit drives and controls the door drive motor 15 to open and close the door.

In such a configuration, the operation control unit 11 operates the car to the required floor in accordance with the designation (designated floor signal 16) by the car call switch 2 or the operation of the hall call switch 6,
After arrival, a door opening / closing permission signal 19 for permitting opening / closing of the door is output to the door control unit 9.

When this operation is performed by the car call switch 2, the door control unit 9
The operator operates the car door open switch 3 to open the door, and operates the hall door close switch 8 after getting off the car to close the open door.

Further, when the above-mentioned operation is performed by the hall call switch 6, the door control unit 9 opens the door when the hall call switch 6 is operated again by a person waiting in this hall, and the car call switch 2 after boarding the vehicle. The open door is closed in response to the designated operation with other floors.

(Problems to be Solved by the Invention) According to the door opening / closing control system described above, it is possible to perform reliable opening / closing control while ensuring safety, but on the other hand, when opening / closing the door, the car call switch 2 and the car door opening switch 3 are provided. The hall call switch 6 and the hall door close switch 8 must be operated appropriately, and improvement in operability has been desired.
In addition, since there are many switches and the like, the number of wires and the like increases, and improvement has been desired in terms of cost reduction.

The present invention has been made in view of the above, and an object thereof is to provide an elevator control device that can contribute to ease of operation and cost reduction while ensuring safe and reliable door opening and closing operations. .

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, in an apparatus having a function of controlling opening and closing of an elevator door by receiving a door opening signal or a door closing signal, the present invention provides: The stop floor detecting means for detecting the stop floor of the car is compared with the detected stop floor and the designated stop floor operated by the car call switch provided in the car. First opening / closing command output means for outputting a door closing signal when they do not match, and when the hall call switch on the stop floor is operated while the elevator door is closed and opened while the car is stopped, respectively. The gist of the present invention is to have second opening / closing command output means for outputting a door opening signal and a door closing signal.

(Operation) In the elevator control device according to the present invention, when the door is opened after the vehicle arrives at the designated stop floor based on the operation of the car call switch, it is executed by receiving the redesignation of the designated stop floor of the car call switch. In addition, when the door is opened and closed while the vehicle is stopped, the door is opened and closed only by the car call switch and the hall call switch by operating the hall call switch on the stop floor.

(Example) Hereinafter, the Example of this invention is described using drawing.

FIG. 1 is a diagram showing a configuration block of an elevator control device according to an embodiment of the present invention. Its features are:
Conventionally, the opening of the door after arrival at the designated stop floor based on the operation of the car call switch 2 which was performed by the car door open switch 3 on the car operation panel 1 is redesignated by the car call switch 2 at the designated stop floor. In addition, the hall door closing switch 8 in the hall operation panel 5 is conventionally used.
By executing the closing of the door during the stop, which was performed by the operation of the hall call switch 6 on the stop floor,
This is because the door can be opened and closed only by the car call switch 2 and the hall call switch 6.

Therefore, as shown in FIG. 1, the car operation panel 100 does not include the car door opening switch 3, and the hall operation panel 500 is provided.
Has a structure without the hall door closing switch 8,
The operation control unit 110 constituting the stop floor detection means is a door control unit 900
On the other hand, the car stop floor information 18 can be output, and the door control unit 900 that constitutes the first and second opening / closing command detection means is configured to perform the opening / closing control based on the car stop floor information 18. In FIG. 1, the same parts as those in FIG. 3 are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 2 is a diagram showing a partial circuit configuration example of the door control unit 900 when the elevator is applied to a building on the second floor. In this circuit configuration, a car stop signal (whether the car is stopped) output from the operation control unit 110 for each floor 18-
1,18-2 and the designated floor signal by operating the car call switch 2 (whether or not designated for each floor) 16-1 and 16-2 Output. That is, for example, when the car is stopped on the first floor (stop signal
If 18-1 is on and 18-2 is off) and the first floor is designated by operating the car call switch 2 (designated floor signal 16-1 is on, 16-2 is off), AND circuit 20a only Is activated and OR
A high level (H) signal is output as a door open signal via the circuit 22. At this time, the input inverting AND circuit 21a outputs the stop signal.
18-1 It does not work because it is input inverted. If the second floor is designated (designated floor signal 16-1 is off, 16-2 on), stop signal 18-2 (off) to drive the car to the second floor.
Only the input inverting AND circuit 21b that has been input
A high level (H) signal is output as a door closing signal via the OR circuit 23. On the other hand, the same applies when the car is stopped on the second floor, and the AND circuit 20b or the input inversion AND circuit 21a operates to output a door open signal or a door close signal depending on whether the floor designated by the car call switch is the same or not. To do.

Therefore, according to the present embodiment, since the door can be opened and closed only by the car call switch and the hall call switch, the operation is simplified and the usability is improved as compared with the conventional device, and the usability is good. It is possible to reduce the number of wires and reduce the cost.

[Effects of the Invention] As described above, according to the present invention, when the door is opened after the arrival at the designated stop floor based on the operation of the car call switch, the designated stop floor of the car call switch is redesignated. When the door is opened and closed, and when the door is opened and closed, the door is opened and closed only by the car call switch and the hall call switch by executing the operation of the hall call switch on the stop floor. Therefore, it is possible to contribute to the ease of operation and cost reduction while ensuring a safe and reliable door opening / closing operation.
