Description

Equipment diagnosis service providing method and system via a communications network and a medium for recording that method}

The present invention relates to a method and system for providing facility diagnosis service using a communication network, and a recording medium storing the method.

For example, in an industrial site operating a facility such as manufacturing, the normal operation of the facility directly affects productivity and work efficiency. Therefore, keeping the equipment in operation as normal is the basic management point to keep the industry competitive.

Nevertheless, until now, most of the operations have been made after an abnormality has occurred in operating such a facility. This is because the deterioration state of the equipment was not detected in advance, but in order to restore the equipment normally in a state in which such an abnormality occurs, it takes a lot of time and money, and there is a problem such as damage caused by the equipment shutdown.

On the other hand, as a way to solve this problem, a method of employing expensive monitoring equipment and facility inspection experts directly on the site may be discussed to check the equipment from time to time, but this also has the disadvantage of costly and manpower consumption. .

Therefore, there is a demand for a service that guides the user to keep track of the status of equipment operated by the user at low cost.

The present invention was created in view of the above necessity, and an object of the present invention is to provide a method and system for providing a facility diagnosis service for receiving a state of a facility operated by a user through a communication network and providing the analysis result, and a recording medium storing the method. There is this.

In addition, the recording medium of the present invention for achieving the above object, the step of receiving and storing the measurement data measured by the measuring device for measuring the status of the user equipment through the communication network; And analyzing the measured data to diagnose the state of the facility and providing the result to the user through a communication network. The program includes a program for executing a process in a computer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a configuration of a computer network system constructed for carrying out the present invention. Referring to the drawings, the user computer 120 is connected to the server computer 110 through a communication network 100 such as the Internet. The server computer 110 includes a processor 111 in which a program for implementing facility diagnosis service is embedded, and a data storage unit 112 for storing various kinds of information. A user may access a web page provided by the server computer 110 through a web browser installed on the user computer 120. Reference numeral 121 denotes a data collector for measuring a state of a user's equipment (not shown), that is, a measuring instrument. The user's computer 120 measures the vibration, noise, temperature, and current change of the equipment. Will be sent to. It is also possible to optionally measure the lubricating oil condition of the machine actuating part and send the analysis. If there are several facilities operated by the user, the measuring instruments will be arranged one by one or moved to one handheld measuring instrument, and the measured data will be measured one by one in a separate file corresponding to each equipment. Will be stored on the computer 120. When the measurement data does not need to be stored in the user computer 120, the instrument 121 wirelessly connects to the communication network 100 wirelessly without passing through the user computer 120, and then transfers the measurement data to the server 110. You can also send it. That is, wired or wireless transmission is selectively possible.

The measurement data is transmitted to the server computer 110 via a communication network automatically or manually depending on the mode. In the automatic mode, the measurement data is transmitted to the server computer 110 immediately after passing through the user computer 120, and the analysis result is automatically transmitted back. The analysis result at this time is a simple alarm message indicating whether the state of good or alarm by comparing the set reference value and the measurement data. In the manual mode, the measurement data is transmitted to the server computer 110 according to the user's instructions, and the analysis result is also confirmed by the user accessing the server computer 110. The analysis result at this time contains a variety of information including the diagnostic opinion. Therefore, the user may select and use at least one of the above modes in consideration of the usefulness of the use of the diagnosis result and the convenience of operation.

First, in the automatic mode, the facility diagnostic service is performed according to the flow shown in FIG. 2. For this automatic mode, software for automatically transmitting measurement data must be downloaded from the server computer 110 and installed in the user computer 120. In this state, when the vibration, noise, temperature, lubricating oil analysis value, current change value, etc. of the target facility are measured by the measuring instrument 121 (P210), the measurement value is collected as measurement data by the user computer 120 (P220). Then, it is automatically transmitted to the server computer 110 via the communication network 100 (P230), and stored in the facility state measurement information DB 112b of the data storage unit 112 (P240). Then, the processor 111 compares the stored measurement data with a set reference value, that is, a reference value set to estimate a normal state and an abnormal state (P250), and compares the result with an alarm message such as 'good state' or 'alarm state'. As an automatic transmission back to the user (P260). This process ends when there is an instruction to end the diagnostic task (P270), but otherwise, the process continues automatically every set cycle. Therefore, the user can quickly determine whether the facility is normal and cope with it without knowing detailed facility diagnosis opinions and the like.

However, if the user wants to see a more detailed diagnosis result, even if not automatic, it is preferable to receive the facility diagnosis service of the present invention in the manual mode. For this purpose, the user first accesses the server computer 110 and has a unique ID and Get a password. Once the user connects to the server computer 110, the processor 111 of the server computer 110 displays a screen as shown in FIG. 4 to confirm whether the user is already a registered member. Registered members can use the facility diagnosis service provided by the server computer 110 after logging in by entering their ID and password.If the member is not yet a member, click the 'Register Member' button to register as a member. As a service can be received. At this time, the registered member information is stored in the member information DB 112a of the data storage unit 112. The processor 111 allocates a partial area of the facility status measurement information DB 112b and the diagnosis result DB 112c of the data storage unit 112 to each registered member, and inputs a facility name or the like to distinguish therefrom. Let's do it. If there are several units, allocate storage space for each unit.

The user registered in the server as described above, as shown in Figure 3a, measures the equipment status with a measuring instrument 121 prepared for measuring its own equipment (S210), and collects the measurement data to the computer 120 (S220). This measurement data includes vibration, noise, temperature, lubricating oil analysis value, and current change value as described above. Then, when it is determined that transmission is necessary to transmit the information (S230), the user is transmitted to the server computer 110 through the communication network 100 (S240), for this purpose, the user is a server computer 110 as in the case of membership registration ) And enter your ID and password. If the ID and password are registered in accordance with the registration, the processor 111 of the server computer 110 displays the 'equipment maintenance situation room' screen for the facilities operated by the user as shown in FIG. This web page is a kind of initial screen that displays and displays a list of equipment registered by the user, special features of each equipment, and various information that the server wants to inform the user. According to the user's wishes, the importance of production of each equipment in this webpage, the price of the machine, the duration of the action according to the difficulty of the repair, the preparation status of the spare parts, and the deterioration of the machine are evaluated and quantified by weighting. It can also be expressed as a facility index.

To transfer measurement data from this screen, click on the 'Data Transfer Room' button on the left side of the screen. Then, the processor 111 displays the 'Data transmission room' screen as shown in FIG. There is a 'Data Transfer' button for each facility that has a history of transmitting measurement data along with the ability to send it. When the user clicks the 'Data Transfer' button, a window for selecting the measurement data file stored in the user computer 120 is opened as shown in FIG. 7. If the file to be sent is selected among them, the selected file is transmitted through the communication network and stored in the space allocated for the corresponding facility of the facility status measurement information DB 112b (S250). The transmission of the measurement data is performed at regular intervals, such as once daily, which is advantageous for accurately analyzing the change in the condition of the equipment on the server side.

The stored measurement data is processed by the processor 111 as a diagram as shown in FIGS. 8A to 8C and stored in the diagnosis result DB 112c (S260). That is, FIG. 8A is a trend chart and data for observing changes in vibration, noise, temperature, lubricating oil state and current state with time, and FIGS. 8B and 8C show measurement data as time waveform and spectral diagrams. This data is useful for analyzing the cause of abnormalities. Of course, the measurement results can be recorded in other ways as well, but for convenience of analysis, it is preferable to convert and store the same type of chart as described above.

Thereafter, the server computer 120 views and analyzes the measured data, creates an opinion and a report on the measured data, and stores the measured data in the diagnosis result DB 112c so that the user can read it (S270). In the next step (S280), unless the user wants to end the analysis, the measurement of the installation status and measurement data transmission continues.

Next, when a user wants to see a diagnosis result of his or her own facility, as shown in the flow of FIG. 3B, the user accesses the server computer 110 (S310), enters an ID and a password, and enters the screen of FIG. S320). If you want to see the diagnosis results of the equipment (S330), click the 'equipment maintenance status room' button on the left side of the screen. Then, as shown in FIG. 9, a screen including the charts of the measurement data and diagnostic opinions thereof is displayed (S331). If the user wants to see the diagnosis result of the facility in a report form (S340), the user may click the 'Report Room' button to view a web page in a daily, weekly or monthly report format as shown in FIG. 10 (S341). ). In addition, if you want communication consultation about the diagnosis result (S350), by clicking the 'diagnostic consultation room' button can also use the ask and answer corner as shown in Figure 11 (S351). And if you want to see the diagnosis result for another facility (S360), go back to the 'equipment maintenance status room' screen of FIG. 9, click the '▼' button of the facility name, and then select the desired facility from the list displayed in the opened window. .

The user who reads the result of the diagnosis will refer to the diagnosis opinion and, if necessary, repair the facility.

Therefore, the user can always grasp the state of his equipment, and can perform the maintenance of the equipment on the basis of this, so that an accident such as equipment failure can be prevented in advance. Schematically, this can be represented as shown in Figure 12, which means that a warning or warning message can be posted in the diagnostic opinion before the deterioration measurement value of the equipment exceeds the defect range, so that the maintenance plan can be established and adjusted in advance. It can reduce the repair time accordingly.

On the other hand, in the present embodiment, an expert is directly arranged on the server side to provide an immediate diagnosis of facilities, but of course, the server may be operated by relaying to other experts.

Meanwhile, the method for providing facility diagnosis services as described above may be programmed and stored in the processor 111 of the server computer 110 as in the present embodiment, or may be stored and used in another computer-readable recording medium. Of course. Computer-readable recording media include all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may include a carrier wave (for example, transmission through the Internet). The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

As described above, the method and system for providing the facility diagnosis service according to the present invention and the recording medium provide the user with the facility to diagnose the state of the facility operated by the user through the communication network so that the result can be read at any time. It provides an opportunity to take countermeasures before a serious fault condition is reached.

It is to be understood that the invention is not limited to that described above and illustrated in the drawings, and that more modifications and variations are possible within the scope of the following claims.
