Abstract

PURPOSE:To precisely judge a cause to restore work, and to secure an efficient rate of operation by analyzing error information, simultaneously displaying a content and a measure and sequentially and repeatedly displaying them in accordance with priority when there are plural measures. CONSTITUTION:An error information analysis part 12 supervises the output of a sensor information input part 11 based on the detection signal of a sensor 4. When it judges it to be an error, a signal is transmitted to a read part 13. The read part 13 retrieves a code against error, transmits it to a display part 15 from an information data base part 14 and displays the content of the corre sponding error and the message of the measure to a display device 2. When there are plural measures, they are sequentially and repeatedly displayed in accordance with previously set priority and frequency data. Thus, even an operator having no enough knowledge for the device can speedily execute appro priate restoration work and he can secure the efficient rate of operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for displaying equipment error messages on a display device for operating production equipment.

When an error occurs in conventional technical equipment, the details of the error are generally displayed on the display of the equipment's control device. In that case, the operator predicts the cause of the error based on his own experience and takes action based on the content of the error.

Errors that occur in equipment directly affect the operating rate of the equipment, that is, the production results, so it is desirable to deal with them quickly and accurately.

Problems to be Solved by the Invention However, in the above-mentioned conventional error display method in the equipment control device, there is no guide for dealing with the error, and the time required to recover from the error largely depends on the skill of the operator. Therefore, in the case of an unskilled operator, it often takes a long time to recover from an error, resulting in a problem that the operating rate of the equipment decreases.

The present invention has been made to solve such problems, and is capable of accurately determining the cause of equipment errors that occur and ensuring the availability of the equipment, regardless of the skill level of the operator. The purpose is to

Means for Solving the Problems The error display method for equipment of the present invention is such that when the control unit detects a specific error, it searches for an error countermeasure corresponding to the error content and displays the error content and error countermeasure at the same time. Features.

In addition, if there are multiple possible error countermeasures for one error content, input the priority of the error countermeasures in advance using the input means, and when the control unit detects a specific error, the error content Error countermeasures corresponding to the error countermeasures are searched for, and the error countermeasures are repeatedly displayed in order of priority.

In addition, when there are multiple possible error countermeasures for one error content, the control unit detects a specific error,
Error countermeasures corresponding to the error content are displayed in order of priority, and when one of the error countermeasures is selected, the frequency of the selected error countermeasure is memorized, and the priority of the error countermeasure is determined based on the frequency. Can be sorted and displayed.

Furthermore, the error contents, error countermeasures, and occurrence date and time that occur in the equipment in operation are memorized, and through predetermined operations, the error history, such as the error contents, error countermeasures, and number of occurrences, is recorded starting from the most frequently occurring errors. They can be displayed in order.

Effect: According to the error display method for equipment of the present invention, the control unit analyzes the information obtained from the sensor unit, and if an error occurs, the content of the error and countermeasures for the error are displayed at the same time. Even an experienced operator can quickly perform error recovery work.

In addition, when there are multiple error countermeasures for one error content, by repeatedly displaying the number of error countermeasures corresponding to the error content in order of priority, appropriate error recovery work can be performed more quickly. I can do it.

In addition, when one of the error countermeasures that are repeatedly displayed in order of priority is selected, the frequency is memorized and the priority of the error countermeasures is rearranged to quickly carry out appropriate error recovery work for each piece of equipment. can be done.

Furthermore, by storing the history of errors when they occur and displaying the error history information in order of frequency by performing predetermined operations as necessary, appropriate maintenance can be performed for each piece of equipment.

EXAMPLES Hereinafter, the present invention will be described in detail based on drawings showing examples thereof. FIG. 1 is a block diagram of a control device used in the error display method according to the present invention, in which 1 is a control section, 2 is a display device, 3 is an input device, and 4 is a sensor. FIG. 2 is an external view of the display device 2 and input device 3, and FIG. 3 is a display example of an error message displayed on the display device 2 of the equipment.

In FIG. 1, a control unit 1 includes a microprocessor, and performs data processing to be described later in accordance with a control program written in a memory (not shown). Now sensor 4
The error information analysis section 12 monitors the input from the sensor information input section 11 based on the detection signal from the sensor information input section 11, and if the error information analysis section 12 determines that the current state of the equipment is an error, it sends the error code to the succession section 13. The successive section 13 uses the error code as a key to search for an error countermeasure code from the error information database section 14 and sends it to the display section 15 together with the error code. In the error information database section 14, data is encoded and stored in a format as shown in FIG. The display section 15 searches for the corresponding error contents and error countermeasure messages using a message table stored in a memory (not shown) and displays them on the display device 2. FIG. 3 shows an example of the display.

At this time, if there are a plurality of error countermeasures corresponding to the error contents, a plurality of error countermeasure codes and their frequency data are sent from the error information database section 14 to the display section 15 through the reading section 13.

The display unit 15 sequentially and repeatedly displays the information according to the frequency data. Furthermore, when the operator operates the input device 3 to select one of the repeatedly displayed error countermeasures and inputs it into the input section 16, the code for the selected error countermeasure is sent to the frequency information update section 17. It will be done. By incrementing the frequency data of the selected error countermeasure, the frequency information updating unit 17 can display error countermeasure messages in order of frequency when an error occurs in the future. Furthermore, by making it possible to display the details of the errors that have occurred and the history of the selected error countermeasures stored in the error information database section 14 on the display section 15 at any time by operating the input section, appropriate maintenance can be carried out for each piece of equipment. It can be performed.

Effects of the Invention As described above, according to the present invention, when an error occurs in the equipment and the operator performs work to recover from the error, appropriate error countermeasures are displayed, so that the operator who does not have sufficient knowledge of the equipment can Even in such cases, quick error recovery work can be performed. Furthermore, when there are a plurality of error countermeasures for one error content, by repeatedly displaying the error countermeasures in sequence according to a preset priority order, it is possible to more quickly and appropriately recover from the error. Furthermore, by rearranging the priorities according to the selection frequency of error countermeasures, even if there are multiple pieces of equipment of the same type, appropriate error recovery work can be quickly performed that corresponds to the characteristics of error occurrence for each piece of equipment. Furthermore, by displaying error history information in order of frequency, appropriate maintenance can be performed for each piece of equipment.
