Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator failure support device for quickly responding to a failure in an elevator using a microcomputer (hereinafter referred to as "microcomputer").

[0002]

2. Description of the Related Art In a building equipped with an elevator, the elevator is an essential daily life item for people who live in the building and those who enter and leave the building, and if a failure occurs in the elevator, A great deal of trouble will occur for those people. Therefore, a mechanism for promptly responding to an elevator failure is adopted. This will be described with reference to the drawings.

FIG. 4 shows an elevator status display device 3 mounted on a control panel 1 of a microcomputer elevator. The status display device 3 includes an input unit 31 and a display unit 32. When a failure occurs, the failure status of the elevator is displayed as a trouble code by operating the input unit 31.
2 can be displayed. In addition, this status display device 3
Can read data, display elevator speed, stop floor, etc., and can also set data for operation adjustment.

FIG. 5 shows an example of a manual corresponding to the trouble code. Here, a manual of "operation mode input signal abnormality" corresponding to the trouble code 23 is shown. This failure is a failure that occurs when the switch that selects the operation method does not operate normally.For example, the maintenance operation mode switch is turned on during normal operation, or in the car operation mode during maintenance operation during car operation. It will be abnormal when the switch is turned on. The electrical connection diagram in the figure shows the function for detecting a failure in the relay sequence. The square marks of the elements in the electrical connection diagram represent relays and the double-line marks represent normally open contacts. 1
In the figure, a to e are all the memories of the microcomputer, the upper character represents the label, and the lower numeral represents the address. XONCG of contact a is at address 4100 for on-car operation mode, XINCG of contact b is at address 410A for in-car operation mode, TX43ER of relay c is at address 4752 for trouble occurrence flag, X of contact d is X
MAIN is for the maintenance operation mode at the address 4110, XNRML for the contact e is for the normal operation mode at the address 4112, and the contact is in the ON state when 1 is entered in the memory data, and is in the OFF state when it is 0. .

Next, a conventional failure countermeasure will be described.
Now, when some kind of failure occurs, the worker inputs a predetermined character into the input unit 31 of the status display device 3, and the display unit 32
Display trouble code on. Next, with reference to the manual corresponding to the trouble code, the memory shown in the electrical connection diagram in the manual is read by operating the status display device 3, and the abnormal portion is found and the failure is dealt with.
For example, that the trouble code 23 is displayed means that the relay c, which is a trouble occurrence flag, is in the ON state.
Both must be ON or both contacts d and e must be ON. In order to confirm this, the address of the memory is input to the status display device 3, and the display unit 32 is turned on.
An error is detected by reading the OFF state. In addition, regarding this technique, Unexamined-Japanese-Patent No. 2-117580 etc. are mentioned, for example.

[0006]

SUMMARY OF THE INVENTION In the above conventional technique,
After reading the trouble code, it is necessary to refer to the manual corresponding to the trouble code and always carry the manual to the site. In addition, the memories shown in the electrical connection diagram in the manual must be checked one by one by operating the status display device 3, and there is a problem that it takes much time to find the cause of the failure. .

The present invention eliminates the above-mentioned problems, and provides an elevator failure support device which makes it unnecessary to carry a manual to the site and can determine the cause of a failure in a short time. is there.

[0008]

In order to achieve the above object, the present invention provides a means for detecting a failure of an elevator controller by a combination of elements of the controller, and a device for detecting the failure. In a failure assistance device for an elevator equipped with a means for storing the data and a means for reading and displaying the data, a portable terminal is connected to the control device, the portable terminal reads the data, and Means for translating the state and means for displaying the state of the data near the element.

[0009]

[Function] When a failure occurs in the elevator, by connecting the portable terminal and the control panel, the trouble code stored in the control panel is read out and the manual corresponding to the trouble code is displayed on the portable terminal. In addition to displaying it on the screen, the status of relays and contacts related to the failure described in the manual is also read and displayed on the screen. As a result, quick failure response can be performed.

[0010]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the construction of an embodiment of an elevator failure support apparatus according to the present invention.

In FIG. 1, 1 is a control panel and 2 is a portable terminal. In the control panel 1, 11 is a storage unit for storing trouble codes and contact data, and 12 is a communication unit for exchanging data with the portable terminal 2. On the other hand, in the portable terminal 2, 21 is a communication unit for exchanging data with the control panel 1, 22 is a control unit for controlling communication, screen display, and data reading, and 23 is a screen display for displaying trouble codes and manuals. 24 is a trouble code manual storage unit for storing a manual corresponding to the trouble code,
Reference numeral 25 is a contact address storage unit that stores the address of the contact shown in the electrical connection diagram in the manual.

FIG. 2 is a flow chart showing the operation of the apparatus shown in FIG. 1, and the operation of this embodiment will be described below with reference to this flow chart.

When some trouble occurs, the worker connects the control panel 1 and the portable terminal 2 (S1). The portable terminal 2 is operated, and the communication unit 21 and the control panel 1 of the portable terminal 2 are operated.
The trouble code in the storage unit 11 is read out through the communication unit 12 (S2). A manual related to the trouble code read by the control unit 22 is selected from the trouble code manual storage unit 24 (S3). Similarly, the contact address associated with the trouble code is selected from the contact address storage unit 25 (S4). Next, based on the selected contact address, the ON / OFF state of the contact is read from the data on the address of the storage unit 11 (S5).
The selected trouble code manual and the current contact state are displayed on the display unit 23 of the portable terminal 2.

FIG. 3 shows an example of a trouble code manual display screen. Here, a manual of "operation mode input signal abnormality" corresponding to trouble code 23 is shown. That the trouble code 23 is displayed means that the trouble occurrence flag relay c is in the ON state,
In order for the relay c to be in the ON state, both the contacts a and b must be ON or both the contacts d and e must be ON. In this case, it can be seen at a glance that both the contacts a and b are turned on, and the inspection work will be performed on the contacts a and b. In addition, since the contact state is emphasized and displayed with diagonal lines or the like, it can be displayed more easily. In this way, the contact state can be easily known, and the failure can be dealt with quickly.

[0016]

According to the present invention, the manual corresponding to the trouble code is displayed on the screen of the portable terminal, and the states of the relays and contacts related to the failure described in the manual are also read and displayed on the screen. Therefore, it is not necessary to carry a manual to the site, the state of the relay or contact at the time of failure can be seen at a glance, and the failure can be dealt with quickly, and the cause of the failure can be investigated in a short time.
