Description

[Detailed description of the invention] The present invention relates to an elevator inspection device.

Usually, computerized elevators are
As shown in the figure, when the push button switch group 4 in the car or at the landing is operated, the ON signal is input to the central processing unit 1 via the interface 2, and the registration is sent to the interface 3.
The registration information is displayed on the response lamp 5 through the registration information, and the car is moved to a predetermined position based on the registered information.

Therefore, when carrying out maintenance inspections, in order to confirm this operation, maintenance personnel had to press each pushbutton switch group 4 and confirm that the elevator was operating as specified. .

Elevators also incorporate a variety of information into their control systems to ensure a comfortable and smooth operation when moving between predetermined floors. In conventional relay-based elevators, maintenance personnel would go to the elevator machine room and visually check the movement of each relay contact to confirm these signals, but with computerized elevators, they cannot be seen visually and inspections are necessary. Some signals are checked by adding light emitting diodes, etc.

However, it is not possible to install light emitting diodes for all signals, so if you want to see more signals, you can attach a maintenance tool to the device and use the switch board and lamp to give the code for the part you want to see using the switch board. is displayed.

This invention was made in consideration of the above points, and it is possible to easily inspect computerized elevators without adding special equipment as in the past, and to shorten the inspection work time. The purpose is to provide an inspection device for

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the elevator inspection device of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing the configuration of one embodiment. In FIG. 2, parts that are the same as those in FIG. 1 are given the same reference numerals, and their explanation will be omitted, and the parts that are different from those in FIG. 1 will be mainly described.

In FIG. 2, the central processing unit 1, interfaces 2, 3, pushbutton switch group 4, and lamp group 5 are the same as in FIG. 1, and in FIG. This is a new addition to the device shown in Figure 1.

That is, in FIG. 2, data is exchanged between the central processing unit 1 and the inspection program storage memory 6, and the central processing unit 1 sends and receives data via the interface 8 to the switch 7 indicating the time of inspection. It is connected.

Next, the operation of the elevator inspection device of the present invention configured as described above will be explained. By setting the switch 7 to the inspection side, the signal from the switch 7 is sent to the central processing unit 1 through the interface 8, thereby causing the central processing unit 1 to switch to the inspection program storage memory 6. Accordingly, the elevator will shift from normal operation to inspection operation and execute an inspection program.

When this inspection program is executed, operations flow according to the flowchart shown in FIG. That is, step 9 in FIG. 3 is an inspection and normal branch program, step 10 is a normal elevator control program, and step 11 is an inspection program.

In FIG. 3, the normal program is inspected and the normal branch program is determined in step 9, and when the normal program is executed, the routine from step 9 to step 10 and from step 10 to step 9 is used to execute the normal elevator control program. is executed.

Therefore, when the switch 7 in FIG. 2 is turned to the inspection side, the program is switched from the normal elevator control program to the inspection program. That is, by setting switch 7 to the inspection side,
From the routine of step 9-10-9 in FIG.
The process switches from step 9 to step 11. This step 11 is shown in more detail in FIG. 4, in which step 12 is a check program for the push button switch group 4 and lamp group 5, step 13 is a command reading program, and step 14 is an actual inspection program. It is.

Now, when moving from step 9 in FIG. 3 to step 11, step 12 in FIG.
Then, the push button switch group 4 and lamp group 5 in the car or at the landing are checked. To give a concrete example of this, by pressing the push button switch group 4 in a predetermined sequence, for example, starting with the push button switch on the first floor, the car position indicator and response lamp corresponding to the pressed floor will be lit for a certain period of time. , lights out.

By sequentially repeating this operation, the push button switch group 4, its interface 2, lamp group 5, and its interface 3 can be easily checked. That is, if one of the lamps does not work, it is known that the interface of that lamp is malfunctioning. Moreover, if neither of them lights up, it is known that there is a failure in the push button switch group and the interface of this push button switch group.

Furthermore, these checks are used to confirm that the command is valid when performing various checks later on.

Next, in FIG. 4, proceed to step 13,
Load the inspection program mode. This is done by a combination of a call push button switch (not shown) and a door open/close push button switch (not shown), and is made possible by assigning an inspection program to each floor. In other words, when a call is made for the first floor and the door close button switch is pressed, mode A is checked; when a call is made for the second floor and the door close button switch is pressed, mode B is checked;
Step 1 according to each instruction.
Execute the inspection program in step 4. The execution results of this inspection program are shown to maintenance personnel using a car position indicator, a call answering lamp, etc. When the display results of these inspection programs show a predetermined pattern, it is said to be normal.

As explained above, according to the elevator inspection device of the present invention, the push button switches and lamps provided in the car and the landing are used to operate the elevator, and the original functions are performed independently of the movement of the elevator. In addition to independently operating the elevator in a simulated manner, parts that were not previously provided, such as acceleration command signals, are displayed on lamps, and the elevator is actually operated in the determined mode, so that the signals etc. operate normally. This system eliminates the need for input means for issuing inspection program execution commands and new tools for displaying the inspection results, and it can be done in a specific location such as a machine room. Adjustments and inspections can be carried out inside the car or at the landing, making maintenance and inspection easier, and the time required for this can be significantly shortened.
