Abstract

PURPOSE:To enhance the safety and service in the case of manual operation by an operator. CONSTITUTION:After turning on an ATT switch 1, when a PSC button 2 is depressed, a door starts closing. At this time, if a luggage or the like carried by the passenger is caught by a door of an elevator cage, he tries to open the door. However, since all doors are inhibited from opening, under an instruction from an all door opening inhibiting means 18, the time of the opening can be saved. Further, if an INH switch 14 is turned on until the elevator cage arrives at a desired floor, the door is inhibited from automatically opening, under an instruction from an automatic door opening inhibiting means 17. After the operator confirms that a hand of the passenger is not caught by a door pocket, the operator turns off the INH switch 14, thereby it is possible to open the door.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control system, and more particularly to an improvement in door opening/closing control of a driver-operated elevator.

0002

[Prior Art] In a driver-operated elevator, the operations entrusted to the driver are (a) service information; (b)
Registering the destination floor, (c) passing the hall call, (d) specifying the direction of elevator travel, (e) starting the elevator,
etc.

FIG. 4 is a block diagram showing a schematic configuration of such a driver-equipped elevator. In this figure, it is possible to switch from automatic operation to manual operation by the driver by turning on the automatic manual changeover switch (hereinafter referred to as ATT switch) 1 provided on the operation panel inside the elevator car. The switch and each button are activated and become usable.

A manual operation signal is input to the door drive circuit 6 from the ATT switch 1, and an operation control circuit 11 is input to the door drive circuit 6.
The elevator operation/stop signal is input from the car 13, and the door opening permission zone at each landing (for example, plus or minus 100 points based on the landing position height) is input from the car 13.
A signal in the range of mm) is input. Due to these signals, when the elevator is stopped within the door-opening permission zone, the door is on standby, and subsequent control of the elevator is left to the driver.

[0005] The driver provides service guidance as necessary, and uses the car call button 7 to issue a car call desired by the passenger. The generated car call signal is input to and registered in the call processing control circuit 9, and then output to the response control circuit 10.

On the other hand, when the hall call button 8 is pressed at the landing on each floor, this hall call signal is also input to the call processing control circuit 9 and registered, and then output to the response control circuit 10. There is.

[0007] The response control circuit 10 takes into consideration the current driving direction, performs calculations for optimum call response, and outputs the results to the operation control circuit 11. Operation control circuit 11
This outputs a running/stop signal to the hoisting motor 12 and drives the car 13. However, the door control circuit 6 is connected to the operation control circuit 11 so that the door will not close unless the driver presses the manual operation start button (hereinafter referred to as the PCS button) 2, and the operation will not start unless the door is closed. Output is restricted.

[0008] Also, when the driver selects the direction selection switch U
When the P button 4 or the DOWN button 5 is pressed, these operation signals are sent to the response control circuit 10, and the driving direction can be forcibly changed. If the car 13 is crowded, the hall call passage switch (hereinafter referred to as P
By operating the AS switch (referred to as AS switch) 3, it is possible to carry out car call priority operation in which only car calls are answered.

FIG. 5 is a flowchart regarding such a conventional elevator control device. In this figure, in the event of an earthquake that disrupts the operation of the elevator, higher control operation is performed and the elevator cannot be operated (step 1).

[0010] When upper control operation is not performed,
When the ATT switch 1 is pressed (step 2), each switch and each button within the broken line in FIG. 4 is activated and becomes usable, as described above. Next, when the PCS button 2 is pressed (step 3), a door closing command is output to the door drive circuit 6 (step 4), and manual operation is started. In addition, P
If the CS button 2 is not pressed, the door opening command continues to be output (step 5) and the operation is not started.

Then, when the UP button 4 or the DOWN button 5 is pressed (step 6), the driving direction is forcibly changed according to the pressed button (step 7). Further, when the PAS switch 3 is pressed (step 8), the hall call from the landing area is ignored (step 9). In addition, a buzzer and an anciator (indicator light) will indicate whether there is a call from each platform.
etc., to inform the driver (step 10).

0012

[Problems to be Solved by the Invention] As mentioned above, in manual operation, most controls are performed according to the driver's intention, but the following two points are not incorporated into the elevator control device. It relies on basic controls. (i) Control of automatic door opening when landing on the destination floor. (ii) Control to fully open the door and then close it again if a passenger's luggage or the like gets caught in the door while the door is closing.

[0013] Therefore, when the control (i) is performed, an accident may occur in which a passenger or driver's hand is on the door and the hand is drawn into the door pocket.

Regarding control (ii), even if it is possible to remove the baggage stuck in the door by opening the door slightly, always open the door completely and then
The control is to close the door again. Therefore, when demand for elevators reaches a peak and prompt operation is required, service to elevator users is reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an elevator control device that can improve safety and service when a driver performs manual operation.

[0016]

[Means for Solving the Problems] As a means for solving the above-mentioned problems, the present invention provides a door driving circuit that controls the opening and closing of elevator doors based on each command signal from a closing operation commanding means and an opening operation commanding means. In addition, in an elevator control device that can perform operational control such as designation of driving direction, hall call pass, etc. either automatically or manually by operating an automatic/manual changeover switch provided on a control panel in the elevator car, a manual operation start button that is provided on the operation panel and sends an operation signal for causing the closing operation command means to output the command signal when the operation control is performed manually; When the elevator door starts to open after it is about to close, an all-door-opening prohibition command is output to the door drive circuit, which prohibits the elevator door from being opened to the end, based on an operation signal generated by the elevator door. means, an automatic door opening prohibition switch that is provided on the operation panel and outputs an operation signal for prohibiting automatic door opening, and an automatic door opening prohibition switch that outputs an operation signal for prohibiting automatic door opening; Automatic door opening prohibition means outputs an automatic door opening prohibition command for prohibiting automatic opening of the elevator door upon landing on the floor to the opening operation command means.

[0017]

[Operation] In the above configuration, when performing manual operation, the driver switches the automatic manual changeover switch to the manual side and then presses the manual operation start button. As a result, the closing operation command means outputs a closing operation command to the door drive circuit, and the door starts the closing operation.

At this time, if the passenger's luggage or the like is caught in the door, the door performs an opening operation, but the all-door-opening prohibition means issues a command to the door drive circuit to prohibit all-door opening based on the operation signal from the manual operation start button. , the door does not open fully, but only slightly. Therefore, the elevator car can move to the destination floor faster.

After the doors are closed and the elevator starts moving, the driver turns on the automatic door-opening prohibition switch. As a result, when the elevator car reaches the destination floor, the automatic door opening prohibition means outputs an automatic door opening prohibition command to the opening operation command means, so that the door does not open automatically. After the elevator car reaches the floor, the driver confirms that no passenger is touching the door, then turns off the automatic door-opening prohibition switch and opens the door. Therefore, accidents such as a passenger's hand being drawn into the door pocket can be prevented.

[0020]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. However, the same components and steps as those in FIGS. 4 and 5 are denoted by the same reference numerals, and redundant explanation will be omitted.

FIG. 2 is a schematic diagram of the entire structure of this embodiment. The difference between FIG. 2 and FIG. 4 is that an automatic door opening inhibition switch (hereinafter referred to as an INH switch) 14 is newly provided, and its operation signal is output to the door control circuit 6A.

FIG. 1 is a block diagram showing the structure of the main part of this embodiment, that is, the door control circuit 6A. As shown in this figure, the door control circuit 6A includes a closing operation commanding means 15, an opening operation commanding means 16, an automatic door opening prohibition means 17, a door opening prohibition means 18, and a door drive circuit 19.

The opening operation command means 15 performs the closing operation not only when an operation signal from the close button is input, but also when an ON signal from the PCS button 2 is input while the ATT switch 1 is on. The command is output to the door drive circuit 19.

[0024] In addition to receiving an operation signal from the opening button, the opening operation commanding means 16 operates when the foreign object detector detects a foreign object caught in the door, and when the elevator car is directed to the destination in response to a signal from the position detector. It is designed to output an opening operation command when landing on the floor.

Next, the operation of this embodiment configured as described above will be explained with reference to the flowchart of FIG.

When the driver turns on the ATT switch 1 (step 2) and then turns on the PCS button 2 (step 3), the operation signal from the PCS button 2 is sent to the closing operation command means 15.
and is sent to the door opening prohibition means 18.

As a result, the all-door opening prohibition means 18 outputs an all-door opening prohibition command to the door drive circuit 19 (step 1).
01), the closing operation command means 15 outputs a closing operation command to the door drive circuit 19 (step 102). Therefore, if a passenger's luggage gets caught in the door when the door is about to close, the door will try to open based on the detection signal from the foreign object detector, but the door will not open fully but only slightly. state. During this time, passengers can pull their luggage inside the door, and the driver can completely close the door by pressing PCS button 2 again.

Thereafter, the control in steps 6 to 10 is performed, and the elevator car heads to the destination floor. During this time, the driver turns on the INH switch 14 (step 103), and the automatic door opening inhibiting means 17 is activated. An automatic door opening prohibition command is output to the opening operation command means 16 (step 104).

When the elevator car lands on the destination floor in this state, the opening operation command means 16 attempts to output an opening operation command based on the detection signal from the position detector, but due to the above automatic door opening prohibition command, the opening operation command means 16 attempts to output an opening operation command. Since this output is tied, the door will not open automatically.

[0030] After the elevator car reaches the destination floor,
The driver turns off the INH switch 14 after confirming that there is no risk of the passenger's hand being drawn into the door pocket. As a result, an automatic door opening prohibition command is output, a door opening command is output (step 105), and the door is opened. In this case, the INH switch 14
Instead of turning off the door, you can also open the door by pressing the open button.

[0031]

As described above, according to the present invention, when opening a door that is once about to close, the door is not fully opened, and the door is automatically opened when the door reaches the destination floor. Since the configuration is such that it is possible to prohibit this, it is possible to improve safety and service when the driver performs manual driving.
