DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of fault location determination support technology that can quickly determine the location of a fault that has occurred in an elevator using a microcomputer for controlling a control panel.

[0002]

2. Description of the Related Art An elevator is a necessity as a means of ascent and descent for living and activities for residents living in and out of the building where the elevator is installed. It greatly hinders activities. For this reason, various measures have been taken to make it possible to quickly take countermeasures when an elevator breaks down. For example, as disclosed in JP-A-4-14358 and JP-A-2-117580, it is known to display elevator failure information on a control panel controlled by a microcomputer. . FIG. 5 is a front view showing a main part of the control panel. As shown in FIG. 1, the control panel 1 includes a display device 3,
By operating the input unit 31, data such as the speed and stop floor of the elevator can be displayed on the display unit 32, data for driving adjustment can be set, and the like. A failure code can be displayed.

When a failure occurs in the elevator, a maintenance worker dispatched to the site operates the input unit 31 to input a command to display a failure code. Then, as shown in FIG. 5, the failure code is displayed by a number on the display unit 32. Therefore, the maintenance person reads the failure code and searches for a page corresponding to the failure code with reference to the handbook brought. FIG. 6 is an explanatory diagram showing the contents of the page corresponding to the failure code "23" in the manual. As shown in FIG.
3 "corresponds to a failure of" operation mode input signal abnormality ". If a switch for selecting an operation method does not operate normally, for example, a switch of a maintenance operation mode is closed during normal operation, This is a failure detected as an abnormality because the switch in the on-car operation mode was closed during the in-car operation in the maintenance operation mode.

[0004] The electrical connection diagram shown in the lower section of the figure shows a function for detecting a fault location in a relay sequence. Two vertically parallel lines are normally open contacts, and a square box is a relay. Represents The states of these elements are all stored in a memory of a microcomputer (not shown) in the control panel 1. The symbols described above the connection lines in the electrical connection diagram represent labels, and the symbols described below the connection lines represent memory addresses. That is, the label XONC of the contact a at address 4100
G is for on-car operation mode, label XINCG of contact b at address 410A is for in-car operation mode, label XAINT of contact d at address 4110 is for maintenance operation mode, 4112
The label XNRML of the contact e at the address is for normal operation mode,
The label TX43ER of the relay c at address 4752 is for a failure occurrence flag.

[0005] These elements indicate that if the data at the corresponding address in the memory is 1, it is on, and if it is 0, it is off.
In the specific example shown in FIG. 6, the failure code "23" is displayed on the display unit 32 of the control panel 1, and it can be seen from the description in the manual that the relay c for the failure occurrence flag is on.
Further, from the contents of the electrical connection diagram, in order for the relay c for the failure occurrence flag to be turned on, both the contacts a and b or the contacts c and d must be turned on. Therefore, the maintenance staff operates the input unit 31 of the control panel 1 to input the address of the corresponding contact, display the ON / OFF state of the contact on the display unit 32, and specify the contact that has failed. Was.

[0006]

In the above-described prior art, the failure code of the failed elevator is displayed on the display section 32 of the control panel 1 so that maintenance personnel can read it. The read fault code is searched for the relevant page by referring to the manual carried by the maintenance personnel, and the ON / OFF state of the contact that may have failed is read from the memory from the contents of the electrical connection diagram described on the relevant page. It must be displayed one by one on the display unit 32 to confirm whether or not there is a failure. Therefore, the manual is an essential portable tool, and if the user forgets the manual, there is a problem that the failure point of the contact cannot be determined, and the work of determining the failure point requires much labor and time.

In an elevator in which the control panel is not provided with a display device, a portable terminal carried by a maintenance person can be connected to the control device of the control panel so that a fault code can be displayed on the display. However, since the format of data sent and received in the communication process with the portable terminal differs depending on the model of the control device, maintenance personnel must be able to communicate with the mobile device using any communication method with any model of the control device. In addition, there is a problem that communication becomes impossible if the connection of the communication means is inappropriate.

The present invention solves the above-mentioned problems in the prior art, and can perform communication simply by connecting to a control device, can identify a failure location in a short time, and can quickly respond to a failure. It is an object to provide a determination support device.

[0009]

The maintenance worker dispatched to the customer building in accordance with the notification of the occurrence of the failure connects the portable terminal 2 carried and the control panel 1 of the elevator (S1).
Next, the maintenance staff operates an operation panel (not shown) of the portable terminal 2 and inputs command information for causing the control panel 1 to read a failure code. Thereby, the control unit 22 communicates with the communication unit 21
Then, a failure code read command is transferred to the communication unit 12 in the control panel 1 via (S2).

When the fault code is read from the storage unit 11 of the control panel 1 and transferred to the portable terminal 2 via the communication unit 12, the control unit 22 stores the fault code from the fault code guide storage unit 24 into the fault code. The corresponding fault code guide information is selected and read (S3). Then, a contact address corresponding to the received failure code is selected and read from the contact address storage unit (S4). Next, the read contact address data is transferred to the control panel 1, the contact on / off data stored in the contact address in the storage unit 11 is read, and the normally open contact of the failure detection circuit detecting the failure is detected.

The process of reading the fault code in step S2 comprises a more detailed subroutine process. FIG. 3 is a flowchart of a subroutine of a failure code reading process. In this process, the maintenance staff first connects the portable terminal 2 to the control panel 1 and then operates the operation panel to read out the codes of various communication data formats from the communication data format storage unit 27 and perform communication. First, a code of the communication data format A having address data having a 6-byte information amount is transferred to the control panel 1 via the unit 21, and it is determined whether or not there is a response from the control panel 1 (S21). .

If the result of the determination is negative, a code of communication data format B having address data consisting of an information amount of 4 bytes is transferred, and it is determined whether or not there is a response from the control panel 1 (S22). ). If the result of the determination is negative, codes of communication data formats C, D,... Having address data having sequentially different amounts of information are transferred, and it is determined whether or not there is a response from the control panel 1. As a result, when there is no response from the control panel 1 to the transfer data of any communication data format read from the communication data format storage unit 27, the portable terminal 2 carried by the maintenance personnel It is determined that data cannot be read because communication is impossible, and the process of this subroutine ends (S23).

In the determination process of steps S21, S22,...
Control panel 1 for transfer data in any communication data format
If a response is received from the control panel 1, the communication data format of the transfer data transferred to the control panel 1 at that time is determined as a communication data format usable for communication with the control panel 1 (S24). Since the address data transferred from the portable terminal 2 to the control panel 1 includes data specifying an area in the storage unit 11 in which the model code of the control panel 1 is stored, the control unit 22 The transfer data read from the storage unit 11 includes the model code of the control panel 1. Therefore, the control unit 22 extracts a model code corresponding to the model of the control panel 1 from the model codes stored in the model code storage unit 26 according to the model code (S25).

Next, based on the determined model data of the control panel 1, address data for reading out the fault code of the control panel 1 is extracted from the address data stored in the fault code address storage unit 28 (S26). . According to the communication data format determined in this way, the control panel 1
And the corresponding fault code is read from the storage unit 11 (S27).

FIG. 4 is an explanatory diagram showing an example of a display screen displayed on the display unit 23 of the portable terminal 2 by the above-described fault location determination processing. In this example, the storage unit 1 of the control panel 1
The fault code "23" and the data of the ON / OFF state of each contact are read from 1 and the fault data of "operation mode input signal error" corresponding to the fault code "23" and the data of the electrical connection diagram are the fault codes. As shown in FIG. 4, the electrical connection diagram including the failed contact and the on / off state of each contact are displayed in a colored manner (shown by diagonal lines).
Is done. Therefore, the maintenance person visually recognizes the ON / OFF state of each contact on the display screen displayed on the display unit 23,
It is possible to immediately recognize what contact should be checked. In this specific example, since both of the contacts a and b are in the ON state, it is understood that it is sufficient to check the quality of these contacts a and b.
