In the case of high-rise or super high-rise buildings, one building may have multiple elevators. For example, if there are three elevators, one operates only on the odd floors, the other one operates on the even floors, and the remaining one operates on all floors or desired designated floors (for example, By operating only on the 10th floor, it is possible to reduce the efficiency and travel time of passengers. However, it may be necessary to change such operating conditions when the operating conditions change, and in this case, operating conditions of each elevator can be easily performed using the operation panel displayed on the monitor. This would be very convenient.

FIG. 8 is a schematic view showing such an example, and a controller C for controlling the operation of the elevator is connected to each of the plurality of elevators, here, three elevators of No. 1 to No. 3, and such a controller is used. Is connected to a cage or door of each elevator or a monitor M provided near the door or a plurality of pin cameras P provided around the monitor. The monitor M is a floor selection button B1 for operating the elevator, and a door. Various buttons including an open/close button B2, a floor selection mode button B3, and a pin camera setting mode button B4 are displayed.

The following shows an example in which the operation of Units 1 and 2 is stopped and only Unit 3 operates on all floors.

FIG. 9 is a flowchart showing the operation control method described above when there are a plurality of elevators. According to this method, first, the floor selection mode button B3 is selected in any one of the elevators. Next, for security and safety, if a password input window is displayed on the monitor M by the controller C so that only an authorized person can connect, the operator inputs the password (S20). ..

If the correct password is entered, in step S30, the controller C displays the elevator selection button, the all floor selection button, the designated floor selection button, the even floor selection button, the odd floor selection button, and the stop button on the monitor M, and the operation is performed. If a person selects one or more of these buttons, the button selected by the controller C is activated.

If the selected button is activated, the completion button is displayed by the controller C in step S40, and if the operator selects the completion button, the elevator operation corresponding to the button selected by the controller C is started, End the process.

FIG. 10 shows in sequence the display of the corresponding monitor M at each step of such a method. That is, the steps described above are executed while proceeding from the left side to the right side of FIG. 10, and FIG. 10A shows the initial state of the monitor display. If the floor selection mode B3 button is pressed in step S10, the display as shown in FIG. 10B is displayed. , Enter the password in step S20. Then, various selection modes for the corresponding machine are displayed as shown in FIG. 10C, and a desired selection button may be pressed in step S30. If the No. 2 machine and even floors are selected, it is displayed as shown in FIG. 10C, and if the No. 3 machine and odd floors are selected, it is displayed as shown in FIG. 10E.

On the other hand, the aiming direction of the pin camera P may be distorted by an external impact. In this case, it is difficult to recognize accurate coordinates via the pin camera. FIG. 11 is a schematic diagram showing such a state, FIG. 11A shows a normal state, and FIG. 11B shows a state in which the aiming direction of the upper pin camera P is distorted by an impact. In the case of FIG. 11B, the line of sight of the upper pin camera P deviates from the original state, and normal coordinate recognition is impossible.

The present invention also provides a method for easily repairing such pin camera error conditions.

FIG. 12 is a flowchart of a method for returning the coordinates of the pin camera to normal.

As described above, the pin camera setting mode button B4 is selected in any one of the elevators (S100). Similarly, when the password input window is displayed on the monitor M by the controller C, the operator inputs the password in step S110. Next, if the correct password is entered, the controller C displays the floor selection button B1 as a coordinate button for setting the pin camera on the monitor M, and the controller C selects the floor selection button B1 as a reference button. If the coordinate button blinks and the operator presses the reference coordinate button, the blinking stops and the reference coordinate for the pin camera is activated (S120).

If the selected reference coordinates are activated, a completion button is displayed by the controller C, and if the operator selects the completion button, the reference coordinates selected by the controller C are set for the pin camera (S130). ).

FIG. 13 shows the display state of the monitor according to each step of this method.

FIG. 13A shows that the pin camera setting mode selection button B4 is displayed. If the button B4 is pressed in step S100, the password input window is displayed as shown in FIG. 13B. When the password is entered, the floor selection button B1 and the guide phrase are displayed as coordinate buttons for setting the pin camera as shown in FIG. 13C. Here, the four corner buttons as the reference coordinate buttons, that is, the B1 floor, B3 floor, 7th floor, and 9th floor buttons are blinking, and if the operator presses the blinking reference coordinate button, the controller causes Such a reference coordinate button is recognized as the corresponding floor, and the pin camera can recognize the correct coordinates.

The present invention also provides a method for a monitor to allow an operator, such as a passenger's finger, to accurately recognize movement in any direction.

For this reason, each of the plurality of pin cameras P captures images side by side on the front of the monitor, and based on such captures, the controller C displays on the monitor M, an xz plane that is perpendicular to the monitor M and horizontal. Establish a right-angled and vertical yz-plane and an xy-plane parallel to the monitor M. FIG. 14 is a diagram showing such a plane. For easy understanding, FIG. 14C shows the coordinate system of the x, y, and z axes by thick lines, and according to such a coordinate system, 14A shows x-z. 14B shows the movement of the finger with respect to the plane, 14B shows the movement of the finger with respect to the yz plane, and 14C shows the movement of the finger with respect to the xy plane. 14A to 14B, the number on the rear side of the monitor indicates the floor number.

As shown in the figure, the vertex angles a, b, and c formed at the vertices are formed while the finger enters and retracts with respect to each plane, and the controller C recognizes such vertex angles, and the vertex angles are, for example, , 30 degrees or less or 40 degrees or less, it can be considered that the floor number (6th floor in the drawing) corresponding to the vertex is selected.

FIG. 15 is a flowchart of this method.

As shown, in step S'10, the controller C sets the xz plane, the yz plane, and the xy plane described above.

In step S'20, the controller C detects the forward and backward movements of the operator including the passenger's finger in the xz plane, the yz plane, and the xy plane, as shown in FIG.

Next, the controller C causes the vertex angles of the vertices caused by the forward and backward movements of the actuator, that is, the vertex angle a in the xz plane, the vertex angle b in the yz plane, or the vertex angle c in the xy plane. When is less than a predetermined angle, the button at the position corresponding to this vertex is registered (S'30).
