Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alarm display device that can be used in numerical control equipment (hereinafter abbreviated as NC4JL equipment) and other equipment.

In addition to warnings such as lamps, buzzers, and displays for equipment abnormalities or abnormalities in the control section, alarm display devices are used to detect the cause of the abnormality early, reduce downtime, and improve operating rates. There is. Conventional alarm display devices generally attempt to express the cause of an alarm occurrence in characters.

However, all conventional alarm display systems are aimed at early detection of the cause of a failure, and do not attempt to display guidelines for troubleshooting. That is, the conventional alarm display device can notify the cause of any abnormality when it occurs. Therefore, apart from particularly knowledgeable operators, the reality is that ordinary operators follow the display content of the alarm and take countermeasures against the cause of the alarm while reading the so-called manual of the equipment concerned.

By the way, with the recent development of NC technology, etc., various devices have become more complex, making it difficult for operators to operate the devices, and even if the location of the failure has been identified, it is difficult to take countermeasures in a simple and short time. be. Furthermore, even when the manual is used, its contents are often complex and difficult to understand, requiring a lot of effort for the operator, resulting in a large amount of downtime.

In view of the above-mentioned prior art, it is an object of the present invention to provide an alarm display device 4 that can detect the cause of an abnormality at an early stage and also quickly take countermeasures against the cause of the abnormality.

To achieve the above object, the present invention provides a summary alarm information table and an explanatory alarm information table corresponding to the cause of alarm occurrence, displays a summary alarm on a display device based on the cause of alarm occurrence, and The alarm display device is characterized in that it includes a display control section that displays the contents of the explanatory alarm information table as desired.

Therefore, in this invention, an explanatory alarm information table is especially provided to explain the causes of alarm occurrences, so that the operator can know the causes of alarm occurrences in more detail and also obtain guidelines on countermeasures. This makes it possible to quickly take measures against the cause of the abnormality.

1 to 6 show an embodiment of an alarm display device according to the present invention. In FIG. 1, a device 3 controlled by a main control section 1 is provided with an appropriate alarm sensor 5, and normal work is being performed. Examples of equipment include NC machine tools, lane equipment, and various other equipment such as plants and boilers. The main control unit 1 detects an abnormality using an abnormality detection signal from the alarm sensor 5 or an abnormality detection means provided inside the main control unit, and notifies the abnormality using a lamp, a buzzer, a display device, etc. This is exactly what Tsutomi does. The main control section 1 is provided with a display control section 1a, and a CRT controller 7
A CRTII with a keyboard 9 attached thereto is provided via the . In addition, the main controller 1 has a summary alarm information table 1.
3 and an explanatory alarm information table 15.

These information tables 13 and 15 are stored in the ROM 17.
is written and used.

The summary alarm information table 13 summarizes information on the causes of alarm occurrence, and includes, for example, the alarm hot spring, the number of the alarm occurrence sensor, or the program number that caused the abnormality. It was established in response to the In addition to emergency stops, items such as overloads, limit switch (sensor) activation, and errors with control values are included. In addition, for example,
If the device is an NC device, errors in interpolation or distribution section, limit operation to 71, encoder error, data loss, system error, etc. are also included.

There are a wide variety of items that are defined depending on the device, but they can be classified as appropriate and expressed in relatively short sentences.

The explanatory alarm information table 15 supplements the contents of the summary alarm information table 13,
An explanation of the relevant alarm is provided at the request of the operator. For example, if the summary information is an emergency stop, the details of the emergency stop, such as [Moe 900's thermal activated. ”, or “Please turn off the power and then turn it on again.”, or “Please open the manual O○ page.” ] The contents of the emergency stop are explained as follows.

FIG. 2 is an example in which the contents of a summary alarm information table are displayed on the CRTll. Alarm display 2 on screen 19
1 and numbered summary information 23 are displayed. This display can be obtained by operating the summary display operation switch 25 on the keyboard 9 based on the occurrence of an alarm.
7 and enter the number indicated in the summary information 23 (number 100 in this example) using the numeric keypad 29. In addition, for NC equipment, HELP
It is also possible to apply B1 ability.

As shown in the flowchart of FIG. 3, step 301
When an alarm occurs, when the summary display operation switch 25 is pressed on the stem 303 to designate an alarm screen, the screen 19 shown in FIG. 2 appears. Step 30
If an explanation is required in Step 5, press the operation switch 27 for explanation display in Step 307, and proceed to Step 3.
By specifying the alarm number that requires an explanation in step 09, an alarm explanation screen can be obtained.

Figures 4 to 6 show alarm causes 31 (31a, 31a,
31b...) and the summary alarm information table 13 (
13a, 13b.) and the explanatory alarm information table 15 (15a, 15b...).

FIG. 4 shows a summary alarm information table 13a for a plurality of causes 31a, 31b, . . .

13b... and explanatory alarm information table 1
5a, 15b, . . . are made to correspond in series in a 1:1 relationship. This is the simplest combination and is used when the number of causes is relatively small and the explanation can be relatively simple. For example, there is a case where an emergency stop number is determined for each alarm sensor 5, and by specifying the number, the procedure for each sensor is explained.

In FIG. 5, a plurality of causes 31c, 31d, . . . are associated with an explanatory alarm information table 1:1, and a summary alarm information table 13 has a plurality of explanatory alarm information 15c, 15d, . This is an example in which one is provided corresponding to the following. This simplifies the display when there are a relatively large number of causes, and allows an explanatory alarm information table to be compiled as appropriate. In this example, since a plurality of causes of occurrence are collectively displayed in one summary alarm information table, a number or some kind of identification code is also written for each cause of occurrence so that it can be distinguished.

In FIG. 6, a plurality of explanatory alarm information tables 15 are provided in parallel or in series, and are read out sequentially according to the operator's request.

Suppose now that an alarm has been generated and an emergency stop has been confirmed in the summary alarm information table 13. Then, in the explanatory alarm information table 15e, 2.
Suppose that it is displayed that there are two possibilities. The operator is
The next instruction can be known by reading either table 15f1 or table 15h, whichever is considered to be more likely. Note that at this time, it is also possible to have the tables 15f and 15h automatically selected based on the determination on the main control section side.

When table 15[ is selected, Table 1 provided in series is used to explain table 15f in more detail.
5g can also be read out.

The examples shown in FIGS. 4 to 6 may be used alone or in combination (71). Therefore, the operator can create an appropriate M-type alarm information table as desired. This allows countermeasures against alarms to be taken in cooperation with the main control unit.In addition, the information is written so that the display on the CRT and the readout with the operator can be performed in a conversational manner. If you keep it in a format, it can be used as a troubleshooting chart, which is even more convenient.

As described above in detail, the present invention provides a summary alarm information table and an explanatory alarm information table corresponding to causes of alarm occurrence, and displays a summary alarm on a display device based on the causes of alarm occurrence. In addition, the present invention is characterized in that it is provided with a display control unit that displays the contents of the explanatory alarm information table as desired, so that it is possible to detect the cause of an abnormality at an early stage, and to quickly take countermeasures against the cause of the abnormality. It is possible to provide an alarm display device that can.
