The present invention relates to an elevator control device including a device, and more particularly, to an elevator control device that facilitates adjustment of riding comfort and landing of the elevator.

[Prior Art] In general, a speed feedback control method is employed in which a car is controlled according to a speed command in order to accurately accelerate and decelerate an elevator car and accurately land on a floor to be stopped.

5 and 6 are, for example, a block diagram of a conventional elevator control device and a circuit diagram of a speed command generating circuit disclosed in Japanese Patent Laid-Open No. 56-161270.

In FIG. 5, 1 is a hoisting electric motor equipped with a control electromagnetic brake 3, 2 is a sheave driven by the hoisting electric motor 1, and a main rope 4 is wound around the sheave 2. Search 4
A car 5 and a counterweight 6 are connected to both ends of the.
8 is a speed detector that is directly coupled to the hoisting motor 1 and generates a speed signal V _T proportional to the rotation of the hoisting motor 1. 9 is a speed command signal V _P and a speed signal V V output from the speed command device 11. _An adder 10 for extracting the deviation signal V _D from _T is a control device for controlling the driving torque or the braking torque of the hoisting motor 1 according to the value of the deviation signal V _D. The speed command device 11 is a computer 1 that generates a speed command signal V _PD of a digital value for each calculation cycle.
11 and D / A that converts this speed command signal V _PD to an analog value
Converter 112, start pattern generation circuit 113 for setting the speed command at the time of start, and output of this start pattern generation circuit 113
It is composed of an adder 114 that adds V _PS (analog amount) and the output V _{PA of the} D / A converter 112, and a smoothing circuit 115 that smoothes the output of the adder 114.

FIG. 1 is an overall configuration diagram showing an embodiment of an elevator control device according to the present invention. In the figure, the same reference numerals and symbols as those of the conventional example indicate the same or corresponding components as those of the conventional example, and therefore, duplicated description is omitted here.

In the figure, 20 is an elevator control device composed of a microcomputer, a CPU 21 that controls the whole and executes a given work, a program that operates and manages the elevator, and a setting for rewriting elevator adjustment data. A ROM 22 that stores programs and other data, a RAM 23 that temporarily stores data and the like necessary for executing an elevator control program and the like on the CPU 21, and an E ² PROM (Electorically) that stores elevator adjustment data. Er
asable and Programmable Read Only Memory: Simply E
² PROM) 24 and an interface 25 for exchanging signals with external devices. These are CPs via a bus 26.
It is connected to U21.

The interface 25 has an operation panel inside the car (not shown)
Various switches provided in the are connected. The switch 27 is an automatic / manual operation switching switch for switching the elevator to an automatic operation mode or a manual operation mode. Further, 28 is a door open button, 29 is a door close button, and 30 ₁ to 30 _n are destinations on the _1st to _nth floors. These are floor registration buttons. One end of these switches is connected to the power supply terminal 33, and the other end is connected to the interface 25.

Next, the operation of the present embodiment thus constructed will be described with reference to the flowcharts shown in FIGS. Second
FIG. 4 to FIG. 4 are flowcharts showing the processing procedure of the elevator adjustment data of the elevator controller in the embodiment of the present invention.

FIG. 2 shows the processing procedure of the main program.

First, when the main program starts with the initial setting of the control device 20, first, in step S1, automatic /
It is determined whether or not the manual operation mode is set by fetching the switch signal of the manual operation switch 27 into the CPU 21. If it is determined that the manual operation mode is not set, the process proceeds to step S2, and the normal operation program stored in the ROM 22 is executed. When it is determined in step S1 that the car is in the manual operation mode, the process proceeds to step S3, and it is determined whether the car is stopped. If the car is moving, step S2 described above is executed. If it is determined that the car is stopped in step S3, the process proceeds to step S4,
It is determined whether the door open button 28 and the door close button 29 have been kept pressed for a predetermined time or more. If it is determined that the door open button 28 and the door close button 29 have not been pressed together for a predetermined time or longer, the process proceeds to step S2 described above. If it is determined in step S4 that the door open button 28 and the door close button 29 have been pressed together for more than the predetermined time, the process proceeds to step S5, and the elevator adjustment data in the E ² PROM 24 is written. Execute the setting program for changing.

FIG. 3 shows a processing procedure of the setting program.

When the setting program starts, steps S10-1 to S10
Depending on 10-n, any destination floor registration button from 1st floor to nth floor 30 _{1 to} 3
0 Determines if _n has been pressed. Here, for example, if it is determined in step S10-1 that the destination floor registration button 30 ₁ for the first floor has been pressed, the process proceeds to step S11-1, and corresponds to the first floor stored in the E ² PROM 24. The elevator adjustment data SET1 is read and written in a predetermined data area A of the RAM 23. Then, in the next step S12-1, the value of the adjustment data A is added or subtracted. When the processing of this addition subroutine (described later) is completed, step S13
Moving to -1, it is determined whether the preceding floor registration button 30 ₁ on the first floor has been pressed. 1 floor destination floor registration button 30 ₁ when it is determined to have been pressed, the process proceeds to step S14-1, and stores the subtraction has been new data A to E ² PROM24. Then, in the next step S15, it is determined whether or not the automatic operation mode is set. When it is determined in step S15 that the automatic operation mode is selected, the process proceeds to the exit. When it is determined that the automatic operation mode is not selected, the process returns to step S10-1 to set the adjustment data for the second floor and below. Move to the program.

Also, if the second floor of the advance registration button 30 ₂ is pressed, which it is determined in step S10-2, step S11-2~ step
S14-2 By executing the same as the above, the value of the new data A for the second floor is stored in the E ² PROM 24. Hereinafter, similarly, the adjustment data up to the nth floor is changed to new adjustment data as needed.

FIG. 4 is a flow chart showing the details of the adjustment subroutine.

First, in step S20, it is determined whether the door open button 28 is pressed. Here, when it is determined that the door open button 28 is pressed, the process proceeds to step S21, and it is determined whether the interlock flag F is "1". Then, when F = 1, proceed to the exit, and when F ≠ 1, shift to step 22 and F = 1
Then, "1" is added to the adjustment data A read in the next step S23.

When it is determined to be "NO" in step S20, the process proceeds to step S24 and it is determined whether the door close button 29 is pressed. If it is determined that the door close button 29 is pressed, the process proceeds to step S25 and it is determined whether the interlock flag F is "1". Then, when F = 1, the process proceeds to the exit, and when F ≠ 1, the process proceeds to step S26 to set F = 1, and “1” is subtracted from the adjustment data A read in the next step S27.

That is, every time the door open button 28 is pressed, "1" is added to the data A.
Is added, and data A is added each time the door close button 29 is pressed once.
"1" will be subtracted from.

Further, in the above-mentioned FIG. 4 and the adjustment subroutine, the interlocking flag F shown in steps S21, S22, S25, S26 and S28 is in the state in which the door open button 28 or the door close button 29 is pressed and is not pressed. It is for receiving the states alternately. That is, the door close button 28 is pressed and steps S20 → S21 → S22
→ When the process proceeds to S23 and the data A is incremented by “+1” and then the process returns to step S20, the door open button 28
Even if is still pressed, since it is determined that F = 1 in step S21, the process does not proceed to steps S22 and S23.

Therefore, once you release the door open button 28, step
Since it goes through S20 → S24 → S28, F = 0 and then the door open button 2
If you press 8, step S23 will be executed. This also applies to the step of subtracting "1" from the data A.
