Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for inspecting an elevator control device, and more particularly to a method for inspecting a control device controlled using a microcomputer.

[Technical background of the invention and its problems]

Recent elevator control devices have built-in microcomputers, and are highly functional in terms of operation methods, speed control, etc.

However, the amount of signals between the elevator control device and external equipment is almost the same as in the case of a conventional control device configured with a relay circuit. Therefore.

The reliability of connections with external devices and ease of maintenance are the same as before.

For example, considering the number of signal lines, if the number of floors serviced by an elevator is 6, there are approximately 30 signal lines between the call registration unit and the control device at each elevator corner, and approximately 80 between the elevator and the car as a whole.
It becomes a root degree. In addition, there are approximately 60 elevators between the elevator halls.
Approximately 20 signal lines between the hoistway equipment are associated with input/output boats managed by a microcomputer within the control unit.

Furthermore, as the number of floors increases, the number of signals in the call registration section and location display section increases proportionally. When the number of signal lines increases in this way, the number of incorrect wirings associated with elevator installation inevitably increases, which not only leads to a decrease in work efficiency but also causes damage to the equipment.

Conventionally, these signal lines were used to directly operate the elevator during installation and adjustment, and to check whether the indicator lights connected to the signal lines were operating normally, and for input signal lines, to check whether they were operating as input. I was using it. The signals input to the elevator control device are the call button in the elevator car, the door open button, the door close button, the door open Sw, and the stop operation 8w for each floor.
, lighting Sw.

There is a buzzer stop switch, a call registration button on each floor on the elevator hall side, and a parking switch on the standard floor + various limits (Svv in the hoistway). Further, signals output from the elevator control device include a call registration lamp, a position indicator light, and a direction light inside the elevator car, and a hall call registration lamp, a position indicator light, a direction light, etc. are installed on the elevator hall side.

It takes time for workers to check these input/output conditions while the elevator is operating, both in terms of numbers and space, and it is difficult to understand whether or not the elevator is operating normally. required the experience of the workers.

Furthermore, to investigate broken lamp bulbs during maintenance, the elevator must be run back and forth while the rungs attached to the halls of each floor must be inspected at a glance, requiring at least two workers.

For this reason, depending on the elevator, it may not be possible to check the status of all input/output devices, which poses a management problem.

[Purpose of the invention]

The present invention has been made in view of the above points, and provides a method for inspecting an elevator control device that allows easy inspection of elevator signal lines and input/output devices during installation adjustment and maintenance.

[Summary of the invention]

The present invention achieves the above object by centrally displaying the status of input/output devices by switching the program of the microcomputer in the elevator control device to inspection mode. One embodiment will be described with reference to the drawings.

Figure 1 shows the elevator hall side. Elevator position indicator lights 1. There are direction lights, 2 hall call registration buttons, and lamps 3 and 4. Here, the position indicator light 1 illuminates the floor numbers. The hall call registration button 3 and the hall call registration lamp 4 are integrated.

FIG. 2 shows the interior of the elevator, and shows the structure of the elevator's position indicator light 5 and elevator operation panel 6. FIG. 3 shows a detailed view 1 of the elevator operation panel 6, which includes a call registration button 7, a call registration lamp 8, a direction light 9, etc.

The operation of registering calls within an elevator car will be described below.

As shown in FIG. 4, the call registration button 7 and the call registration lamp 8 are directly driven by the elevator control system [10], and are respectively driven by the human cover sofa device 11. Output bumper device 12tl
- is converted into data that can be handled by the central processing unit 13.

The input buffer device 11 has the function of converting the level of the signal from the call registration button 7 through a photocoupler, and the output buffer device 12 has the function of converting the level of the signal from the call registration button 7 through a photocoupler and a transistor. The registration lamp 8 is driven.

The central processing unit 13 is composed of a CPtJ that performs control, a ROM that stores programs, and an I (AM) that stores data.

For example, when the elevator is in normal operation, press the call registration button 7.
When you press 3K (call button on the 3rd floor), central processing unit 1
At 3, the signal 3 is confirmed, the L3K (call registration lamp for the 3rd floor) is turned on, and the elevator starts moving toward the 3rd floor.

However, in the present invention, for example, by inserting a separately provided inspection switch (not shown) to run an inspection program different from the program for normal operation,
The purpose is to check the call registration button 7 and the call registration lamp 8.

FIG. 5 shows a register configuration of the call registration section of the central processing unit 13, and FIG. 6 shows a flowchart in this example.

The signal of the call registration button 7 is read from the input buffer device 11 in steps 1 and 2 of FIG. 6 and stored in the call processing register 14 shown in FIG.

In this register, the call registration button is number L and K is pit 0.
, 2K are arranged in bit 10) order and converted into 1-note data. Therefore, if only 3 is input, the value of this register will be 000001000. This call registration register (is transferred to the call output register which is a register for the call registration lamp 8 in step 3, and the state of the 10 call registration button 7 is displayed on the sweet call registration lamp 8 in step 4.

Therefore, if you press 31(, L3K lights up, and if you release it, L3
K is programmed to turn off the light.

By running this program, the worker can find out if there is any miswiring in the call registration section No. 111, if there is a poor contact in SW, if the lamp is burnt out, etc. As a result, checking of call registration in an elevator car can be completed in a few tens of seconds, resulting in a significant reduction in work time compared to the case where inspection could not be performed without the conventional technology. Furthermore, since the inspection method is simplified, anyone can perform the inspection. Further, the program can also be used as a normal program for other operations by matching the registers, and the number of program steps required for this operation can be approximately 100 bytes.

In the above example, inspection of the call registration section has been described, but when the call registration button 7 is pressed, the corresponding position indicator light 5e is turned on, making it possible to inspect the call registration section and the location display section at the same time. To accomplish this, all that is required is to add a routine between steps 3 and 4 of FIG. 6 to transfer the data in the call registration register to the position display register.

As a result, when 3K of the call registration button 7 is pressed, L3 of the call registration lamp 8 and the number 3 of the position indicator lamp 5 light up, allowing simultaneous inspection.

FIG. 7 shows a flowchart of an elevator control system incorporating the present invention. Whether the program performs normal operation or inspection operation is determined by inspection 8w. In the case of inspection operation, in addition to the elevator car call check routine shown above, elevator hall call check, elevator hall position display check elevator car interior 8w By similarly adding the 8w check routine (check, hoistway limit), comprehensive investigation of elevator maintenance becomes possible.

FIG. 8 shows a flowchart of the 8w check inside the elevator car.

The corner F3w is installed at the bottom of the elevator operation I channel, and is unrelated to the number of floors serviced. Therefore, in this example, the input status of the 8w type is expressed by the number of times a buzzer attached to the car rings.

However, with this method, it cannot be determined when all Sw are inserted, so the moment when each Sw is inserted (UP edge)
to be detected. Also, the 11% movement period of the buzzer is 0.
．． About 5 seconds is sufficient.

If the method shown in FIG. 8 is used, it is possible to check the equipment even if the input and output numbers do not match. This method also uses an indicator lamp and gong instead of a buzzer.

It is also possible to use a chime or the like.

〔Effect of the invention〕

As explained above, according to the present invention, inspection can be carried out without actually operating the elevator, so during installation, all input/output points 41 can be performed before the elevator installation is completed, thereby shortening the construction period. Additionally, since the program only manages static items such as the 8W, lamp, and fuser, it also prevents damage to main equipment due to incorrect wiring.
