When the data of the facility is selected, the selected program is executed in response to the user's request, and the result is provided to the user.

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

First, a preferred embodiment according to the present invention will be described in detail with reference to FIGS. 1 to 12.

1 shows an example of the configuration of a computer network system constructed to carry out the 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). Immediately and 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. 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 inputting 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 some areas 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 facility names and the like to distinguish them 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 a file to be sent is selected, 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 password, and enters the screen of FIG. 5 described above ( 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 above-described 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.

Hereinafter, another preferred embodiment according to the present invention will be described in detail with reference to FIGS. 13 to 21C.

Figure 13 shows another example of a computer network configuration constructed to carry out the present invention.

14 is a flowchart illustrating a process of using a facility diagnosis service of the present invention by a user. In order to use the programs and the database provided by the server computer 110 shown in FIG. 13, the user first accesses the server computer 110 and receives a unique ID and password. Once the user connects to the server computer 110, the main program 111a of the server computer 110 checks whether the user is already a registered member. The registered member can use the facility diagnosis service provided by the server computer 110 after logging in by inputting an ID and password. If the member is not yet a member, the registered member can receive the service as a registered member. At this time, the registered member information is stored in the member information DB 112a of the data storage unit 112. In addition, the main program 111a is the facility status measurement information DB 112b, the diagnosis result DB 112c, the facility maintenance technical data DB 112d, and the facility diagnosis case DB 112e of the data storage unit 112 for each registered member. And allocates a partial area of the facility related data DB 112f and inputs a facility name and the like to distinguish therefrom. If there are several units, allocate storage space for each unit.

The user registered in the server computer 110 as described above, as shown in Fig. 14, measures the equipment status with a measuring instrument 121 prepared for measuring its own equipment (S300), and the measured data to the computer 120 ) To collect (S302). This measurement data includes vibration, noise, temperature, lubricating oil analysis value, and current change value as described above. When the information is collected, the user transmits the information to the server computer 110 through the communication network 100. For this purpose, the user accesses the server computer 110 and registers the ID and the ID with the ID. Enter your password. When the ID and password are registered and logged in, the main program 111a of the server computer 110 displays a 'equipment maintenance situation room' screen for facilities operated by a user similar to FIG. 5. However, this screen is not only the facility status maintenance room, data transmission room, report room, diagnosis consultation room displayed on the facility maintenance status room screen of FIG. 5, but also a diagnosis room, a search room, and a management room. Includes more. Of course, as in the above embodiment, the weight is applied after evaluating the importance of the production of each facility in the web page, the price of the machine, the duration of the action according to the difficulty of the repair, the preparation of the spare parts, and the deterioration of the machine. It can also be shown as a facility index quantified.

The method of transmitting the measurement data is the same as in the above embodiment. That is, in the manual mode, clicking the 'Data transmission room' button on the left side of the screen displays the 'Data transmission room' screen shown in FIG. For each facility, there are 'Data Transfer' buttons that can transmit it along with the history of transmitting the measurement data. For example, when the user clicks the 'Data Transfer' button, the user's computer ( A window opens in which you can select the measurement data file stored in step 120). 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 (S304 and 306). Similarly, in the automatic mode, the software is downloaded from the server computer 110 and installed in the user computer 120, and then the vibration, noise, temperature, lubricant analysis value, current analysis value, and the like of the equipment collected by the instrument 121 are displayed in the communication network ( 100 is automatically sent to the server computer 110.

When the measurement data is transmitted to the facility state measurement information DB 112b, the main program 111a of the server computer 110 determines whether the user directly diagnoses or requests a diagnosis.

When the user requests a diagnosis, the server computer 110 checks and analyzes the user's facility status measurement information stored in the facility status measurement information DB 112b, diagnoses the cause of the abnormality of the facility, and writes an opinion and report on it. The diagnosis result is stored in the diagnosis result DB 112c so that the user can read it in the future. (S326, 328)

However, when the user directly diagnoses the facility, the user clicks the 'diagnosis room' button displayed on the 'equipment maintenance situation room' screen. (S310) When the 'diagnosis room' button is clicked, 'facility monitoring', 'facility diagnosis', Displays the diagnosis room screen including the 'Repair Equipment' button (S312).

First, the main program 111a of the server computer 110 determines whether the user selects the 'facility status monitoring' button. (S314) When the 'facility status monitoring' button is clicked, the status monitoring program is executed to install the equipment from the user. Enter the specification and set the standard value for estimating the normal and abnormal conditions of the equipment. (S314) The equipment specification and the standard value are input by the user directly or the list of equipment already registered by the user in the facility maintenance status room. The standard value can be arbitrarily changed by the user at any time in consideration of the ISO standard value provided by each facility and the importance of each facility.

Then, the user receives the measurement data of the corresponding equipment from the data of the user equipment stored in the facility status measurement information DB 112b, and executes the program to output the execution result indicating the trend of the equipment. (S318, 320) Further, the search is performed. Using the program, the facility maintenance technical data DB 112d and the facility diagnosis case DB 112e are searched to provide data or examples of a type similar to the trend state of the facility. A trend chart for observing changes in noise, temperature, lubricating oil state and current state, Fourier transform of vibration, noise, etc. An example of the execution result is shown in FIG. 15 including a waterfall chart and the like. FIG. 15 provides a trend chart showing the total vibration of the motor occurring in the vertical direction on the motor load side with time, a time waveform diagram, and a spectral diagram showing the change with frequency by Fourier transforming the total vibration.

The user can use the output result to monitor the current state of the equipment and to predict the future failure time. Of course, if it is determined that there is an abnormality in the equipment as a result of the output, it is possible to request equipment diagnosis to the server computer 110 side, or can directly diagnose the cause of the equipment using a professional diagnostic program.

Therefore, the main program 111a of the server computer 110 determines whether the user will request facility diagnosis (S324), and if there is a facility diagnosis request from the user, the server computer 110 side of the user's facility status measurement information DB View and analyze the measurement data and program execution result stored in the 112b, diagnose the cause of the abnormality of the facility, make an opinion and report about it, and store the result in the diagnosis result DB 112c for future viewing. S326, 328)

However, if there is no facility diagnosis request from the user, the state monitoring program is terminated. (S330) If the user does not end the state monitoring program 111b or does not select the state monitoring program 111c, the user clicks the 'expert diagnosis' button. (S332) When the 'special diagnosis' button is clicked, the expert diagnosis program is executed and the equipment specification is input from the user. (S334) Of course, the equipment specification is already registered in the 'equipment maintenance situation room'. A list of available facilities is available.

And the user receives the data from the user equipment data stored in the facility status measurement information DB (112b) and executes the program to output the execution result. (S336, 338) And using the search program facility maintenance technical data DB ( 112d) and the facility diagnosis case DB 112e is searched to provide data or an example of a type similar to the output result. (S340) However, unlike the case of the state monitoring, the equipment state measurement information for the professional diagnosis is performed. It requires vibration, deterioration of temporal continuous data, magnitude of deterioration of equipment according to speed change of rotating machine, and phase value. The execution result is the vibration amplitude according to the change of natural frequency and operation speed, the board diagram showing the change of phase angle, the polar diagram showing the change of vibration amplitude and phase angle for the change of operating speed, the shaft system according to the change of operating speed such as the natural frequency. A cascade plot showing the Fourier Transform spectrum change of the response of and a Waterfall chart showing the Fourier Transform spectrum change over time are shown in FIG. 16. . FIG. 16 is a polar diagram and a board diagram showing vibration amplitude and phase angle change, and a spectral diagram showing a change in frequency by Fourier transforming the total vibration of the motor in the vertical direction on the motor load side. Hazard velocity diagrams that show changes in the FFT spectrum of the response of the shaft system with changes in operating speed, such as time waveform diagrams and shaft natural frequencies.

In general, the user may execute the professional diagnosis program 111c when an abnormality of the facility is expected by using the state monitoring program 111b. As in the case of executing the state monitoring program 111b, the user can analyze the output result to predict what is the cause of the abnormality of the facility. However, if it is not possible to analyze the cause of the equipment failure by using the output result, you can request the equipment diagnosis to the server computer (110).

Therefore, the main program 111a of the server computer 110 determines whether there is a facility diagnosis request from the user (S342), and when there is a facility diagnosis request from the user, the server computer 110 side as in the case of the state monitoring. The measurement data and program execution result stored in the user's facility status measurement information DB (112b) to analyze and diagnose the cause of the abnormality of the facility, create an opinion and report on it, and then view the diagnosis result DB for future users. (S326, 328) However, if there is no request for facility diagnosis, the program ends. (S344)

If the user does not exit or select the professional diagnosis program 111c, it is determined whether the 'equipment repair' button is selected. (S346) In general, the user determines whether the user has selected the status monitoring program 111b or the professional diagnosis program 111c. In case of predicting the cause of abnormality of equipment, select 'Repair Equipment' button.

When the 'Repair Equipment' button is selected, the main program 111a provides various types of programs 111d for repairing the facilities. The repair program includes a balancing program, a rotating shaft axis alignment program and an analysis program, and may include other programs for repair.

When the user selects one program among the equipment repair programs (S348), the main program 111a receives the necessary data for each program for equipment specifications and equipment repair by executing the selected program (S350 and 352). Using the received data, the state of the facility after correction is presented (S354). If the user is satisfied with the state of the facility after correction (S356), if not, the data is input again to determine the condition for the satisfactory facility. If so, the program ends if it is satisfied (S358).

For example, if a user selects a balancing program in anticipation of an unbalance of a rotating machine, this is done to install the initial vibration measurement data of the facility and the test weight size and test weight for eliminating unbalance. Get the location. The vibration data of the calibrated equipment is then presented when the test weight is installed. If the user is not satisfied with the vibration data of the equipment after calibration, input the size of test weight and the location to install again and provide the vibration data of the equipment after calibration to reduce the vibration of the equipment. An example is shown in FIG. 17A, which provides a location for installation.

In addition, if the user selects the axis alignment program in anticipation that the cause of the equipment is the axis alignment of the rotating shaft system, it is executed and the initial axis alignment state of the equipment and the current state of the equipment measured by the user by the dial gauge or the laser measuring instrument. A condition for axis alignment is given by inputting the axis alignment state of the circuit and an example thereof is illustrated in FIG. 17B.

Similarly, when the user selects an analysis program to verify and analyze the design status of the equipment, the user executes it and receives the design data related to the equipment, such as equipment specifications, and the vibration response from the actual operating speed. Hazard rate to analyze the natural frequency for and present the unbalanced response and mode analysis results for resonance conditions that may cause excessive damage by comparing with the data input from the user, and to change the design problems of the equipment. Providing diagrams, etc., allows users to perform design verification and simulation of the design status of the facility. An example of such an analysis program is shown in FIG. 17C, and an example of a hazard velocity diagram is shown in FIG. 17D. The diagram shown in FIG. 17D represents a limit of the actual operating speed with respect to the support stiffness of the equipment, and the user can change the support stiffness of the equipment so that the actual operating speed does not resonate with the natural frequency of the equipment.

As shown in the above example, when the user has an abnormal cause in the facility, the user can execute the corresponding facility repair program to obtain the conditions for the facility repair and directly repair the facility using the facility.
