With the advent of the network information age, how to use advanced and convenient methods to realize the scientific management of information has become the focus of information construction in various fields. The role of the equipment management and monitoring system is to scientifically manage equipment information. For process industry enterprises such as petroleum and chemical industries, their equipment management is different from that of general enterprises. It must be effectively combined with a large number of existing equipment process flow charts to realize equipment management. efficient management.

However, the existing equipment management systems all manage equipment in the form of catalogs, which cannot combine equipment image information and equipment process flow, but only provide equipment business data, which is monotonous, boring, and poorly readable. , and the comprehensive utilization rate of information resources is low.

First of all, most of these systems are based on the statistics and management of basic information and ledgers based on equipment catalogs, and do not introduce a large number of process flow charts, that is, process management and equipment management are separated from each other, and effective information integration cannot be carried out according to the process flow. As a result, information transmission in the system is not smooth, and it is impossible to effectively manage enterprise information resources as a whole.

Second, these systems fail to provide users with an intuitive reference. The graphic information in the existing technological process is different and incompatible with each other, and it cannot be directly introduced into the equipment management system, so as to improve the sensory awareness of the administrator, and then improve the quality and efficiency of equipment management.

Thirdly, when the managed equipment of these systems fails or undergoes maintenance, the user is required to manually fill in the failure phenomenon or the maintenance plan. As a result, a lot of repetitive work is wasted, manpower is wasted, and it is impossible to provide reference for follow-up work, and it is also impossible to obtain guidance based on previous work.

In addition, most of these systems are C/S mode. It needs to install a dedicated client on each management terminal. When the system changes, all system terminals need to be updated, and the maintenance workload is heavy.

According to the equipment management and monitoring system of the present invention, it can also include equipment operation state acquisition subsystem, which is a data acquisition and control system, which can be a DCS system or an MES system, which collects the control information of reactor devices, catalytic devices, boiler rooms, tank farms, etc. The data of the system is sent to the real-time database table through the data interface, and displayed in real time on the computer in the central control room through the local area network.

As shown in Figure 2, the equipment management and monitoring system of the present invention allows users to manage equipment information through process flow charts. The flow chart drawing and management module provides users with the design interface of SVG graphic elements and SVG process flow charts, sends the designed SVG graphic elements to the database subsystem and saves them as static files of the vector graphics element library, and saves the designed SVG process flow charts The diagram is sent to the database subsystem and saved as a static file of the vector process flow chart, and the equipment is bound with the unique identification code GUID of the corresponding SVG graphic element. The flow chart and equipment information interaction module obtains the SVG graphic elements stored in the static file of the vector graphics element library and the SVG process flow chart stored in the static file of the vector process flow chart, and provides the user with a display interface of the process flow chart; when the user clicks the When describing the equipment shown in the process flow chart, the flow chart and equipment information interaction module are linked to the basic information management module, fault information management module, maintenance information management module, maintenance information management module and spare parts information management module according to the unique identification code GUID of the equipment One or more of them, and then display the information of the equipment, and manage the failure, repair and/or maintenance information of the equipment; The interaction module unbinds the binding and binds the SVG primitive of the device to its corresponding GUID of the device.

The SVG graphic element is designed by the user and saved in the static file of the vector graphic element library, using SVG and Cascading Style Sheet (CSS) to jointly control the browser output of the equipment drawing, and realizing the intelligence of the graphic element through the unique equipment identification code GUID and DOM technology identify. The unique identification code GUID identifies each device. Through the GUID, the flowchart and the device information interaction module can be linked to the basic information management module, fault information management module, maintenance information management module, maintenance The information management module and the spare parts information management module, that is, the GUID is used as a mapping identifier between the graphic element and the corresponding equipment attribute information. If the binding between the SVG graphic element and the device GUID is wrong, you can manually unbind it first, and then bind the SVG graphic element to the GUID of the corresponding device. The interaction between the display of the flowchart interactive subsystem and the database subsystem is realized through AJAX technology. The flowchart interactive subsystem sends the device GUID code to the database subsystem, and the database subsystem returns relevant information organized in JSON data format. The flowchart The interactive subsystem displays the received data on the dialog box of the browser. In addition, for each device, if you want to view the internal structure information of the device, you can display secondary information, which is to control the visibility attribute of the detail layer of the SVG drawing.

The SVG process flow chart is mainly composed of SVG graphics elements and pipelines. SVG primitives include two kinds of primitives: shape primitives and image primitives. Figure 2 is an example of a shape primitive and an image primitive, and Table 1 is a comparison table of attributes of a shape primitive and an image primitive. The shape primitive is relatively simple, emphasizing the outline (geometric attribute) of the primitive, and the image primitive is more complex, emphasizing the outline (geometric attribute), style and animation effect of the primitive. The image primitive is to make up for the defect that the shape primitive only includes the outline of the primitive, which is very unrealistic. For the graphic elements of the stereoscopic effect, it is realized by color gradient. Define different gradient stops for highlights and lowspots. And set the gradient extension method to specular reflection to complete the three-dimensional lighting effect of the device. Table 2 is the BNF description of SVG primitives, which defines the composition of SVG primitives in detail. According to its complexity, SVG graphics can be stored in any form in Table 3-4 in the static file of the vector graphics library, and the import method in Table 5-6 can be used. SVG pipelines can be rendered using markers for SVG line endpoints, and in SVG drawings, there are some lines with markers such as arrows. Unify all pipeline arrows by defining markup elements that are reusable and defined under the SVG defs tag.

In SVG, multi-layer drawing is supported, and the image of the device is drawn from the outline layer to the detail layer, and then the visibility of different layers is controlled to achieve the effect of multi-layer display of device information. At the same time, add an onclick event to the clickable element. If multiple elements together constitute a clickable element, you can set a mask graphic that covers all clickable elements and is completely transparent, and add an onclick event to the mask graphic. In the onclick event, use Ajax technology, JSON data exchange format to interact with the background, and use the unique GUID number of the device to realize the correspondence between the SVG graphics and the device.

The system provides a Web drawing tool for drawing SVG drawings (or use the Google open source project SVGEditor). For the actual situation of a large number of existing process flow charts in the enterprise, the existing drawings can be imported into the tool as the base map (background map). The layer is named action layer, and the graphics of this layer can recognize mouse click events. When saving the drawing, the background image is ignored, and the onclick event is automatically set for the clickable area. The content of the onclick event specifies the API call for the flow chart and the equipment information interaction module, and saves the SVG file to the static vector process flow chart on the server. document. The management of the flowchart is to view, add, modify, and delete static files in the file system.

The flow chart and equipment information interaction module described in the present invention provides a new perspective based on the flow chart, combines the production process with the equipment life cycle to realize integrated dynamic management, and uses multiple layers to display process flow charts with different levels of detail, both You can view the relationship between devices from a global perspective, and you can also go deep into the device to view the internal structure. Compared with the traditional way of using the device catalog to manage device information, using the flowchart can manage device information more conveniently and quickly.

As shown in FIG. 4 , the device management and monitoring system of the present invention can allow users to manage devices in real time. The equipment real-time status monitoring module queries the equipment operation status information stored in the real-time database table, and displays the equipment real-time operation status display table in the process flow chart interface; the real-time database table is updated in real time according to the equipment information collected by the equipment operation status acquisition system ; The equipment running status collection system can be DCS system or MES system. The equipment operation status indicator table is drawn by SVG technology, and JavaScript code is embedded at the same time, which is used to regularly fetch data from the real-time database table to update the indicator table (modify the corresponding element value in the SVGDOM tree structure). Between the equipment real-time status monitoring module and the real-time database, data is exchanged through HTTP protocol and JSON data format. Compared with XML, JSON data format is lighter, shorter and suitable for network transmission. In addition, the device real-time status monitoring module allows changing the update frequency of the page by adjusting parameters. When the network speed is slow, a lower update frequency should be selected.

The device real-time state monitoring module described in the present invention does not need to install additional software or plug-ins, and can observe the current running state of the device in real time, so as to achieve the purpose of real-time monitoring and safe operation of the device.

As shown in FIG. 5 , the equipment management and monitoring system of the present invention can allow users to record faults. When the user clicks on a device in the process flow chart and selects the fault entry function, the flow chart and device information interaction module receives the fault information of the device (including fault time and fault responsible person) input by the user, and The information management module interacts and sends the fault information to the fault information management module. The fault information management module reads and parses the system parameter configuration file, and obtains a list of common faults, so as to give the possible fault phenomena of this type of equipment; The importance level of the fault and the recommended maintenance plan are sent to the flow chart and the equipment information interaction module for user reference; if the fault does not exist in the list, a reminder is sent through the flow chart and the equipment information interaction module to The user manually enters the fault phenomenon and consults the severity level of the fault and the suggested maintenance plan to the experts. Afterwards, by configuring the system parameter configuration module of the management subsystem, the faults manually entered by the user can be written into the common fault list in the system parameter configuration file, so as to provide reference for the next fault. Finally, upload the fault picture through the flow chart and the equipment information interaction module to complete the fault entry process. Among them, in the system parameter configuration file, the common fault list is stored in the form of quaternion <device directory, fault phenomenon, importance level, and suggested maintenance plan>.

As shown in FIG. 6 , the equipment management and monitoring system of the present invention can allow users to enter maintenance. When the user clicks on a certain equipment graphic element in the process flow chart and selects the maintenance input function, the flow chart and equipment information interaction module first interacts with the fault information management module according to the GUID of the equipment. The fault information management module judges whether there is a fault in the device. If there is no fault in the device, the notification flow chart and the device information interaction module will inform the user that maintenance entry cannot be performed. Conversely, if there is a fault in the device, the notification flow chart and the device information interaction module display the fault list of the device. The flow chart and equipment information interaction module sends the fault items selected by the user to be repaired and the maintenance information (including maintenance time and maintenance personnel) input by the user to the maintenance information management module. The maintenance information management module reads and parses the system parameter configuration file to obtain a list of common maintenance schemes for this type of equipment; if there is a corresponding maintenance scheme in the list, it will be directly sent to the flow chart and equipment information interaction module for user reference; If there is no corresponding maintenance scheme in the list, a reminder is sent to the flow chart and the equipment information interaction module to remind the user to manually enter the maintenance scheme. Afterwards, the maintenance scheme manually entered by the user can also be written into the list of common maintenance schemes in the system parameter configuration file through the system parameter configuration module of the configuration management subsystem, so as to provide reference for the next maintenance. If the maintenance plan includes the step of replacing spare parts, an application for the use of spare parts is sent to the spare parts information management module; the spare parts information management module queries the spare parts information database table, judges whether there are required spare parts and whether the quantity of required spare parts is sufficient, and feeds back the judgment result To the flowchart and equipment information interaction module. Among them, in the system parameter configuration file, the list of common maintenance schemes is stored in a one-to-one correspondence manner of the binary group <equipment catalog, maintenance method>. The maintenance information management module can also count the faults of each device and the corresponding maintenance situation, and provide a maintenance method knowledge base for potential faults in the future.

As shown in Fig. 7, the equipment management and monitoring system of the present invention can also allow the user to modify or delete the maintenance plan. When the user clicks on a device and chooses to modify or delete the function of the maintenance plan, the flowchart and the device information interaction module interact with the maintenance information management module according to the GUID of the device. The maintenance information management module obtains the corresponding maintenance plan of the equipment and feeds it back to the flow chart and the equipment information interaction module for the user to modify or delete the corresponding maintenance plan. However, for a maintenance plan that includes replacement parts, if the application for the use of spare parts has been approved, in order to ensure data consistency, the maintenance plan cannot be modified or deleted.

The fault information management module, maintenance information management module, and system parameter setting module of the present invention jointly establish a set of equipment failure and maintenance method library. When the same failure occurs in the equipment next time, it is not necessary to repeatedly enter the equipment failure, but from the Select from the list of possible equipment failures for the equipment. At the same time, it can also propose a feasible suggested maintenance plan and a reliable fault severity level for the fault. In addition, when adopting an existing maintenance scheme next time, the maintenance scheme can be directly selected in the maintenance scheme list without repeated entry, thereby reducing repeated manual entry.

As shown in FIG. 8 , the equipment management and monitoring system of the present invention can remind users of failures. When a user logs into the system for the first time, the fault information management module sets the number of read fault entries for the user and initializes it to 0. Thereafter, each time the user interacts with the system, the fault information management module needs to determine whether there is a new fault for the user that needs to be reminded. First obtain the number of existing fault entries for the user, if the number of existing fault entries is equal to the number of read fault entries, no reminder is needed this time. Otherwise, if the number of existing faulty entries is greater than the number of read faulty entries, a fault reminder is initiated to the user. Specifically, call the desktop reminder API of the corresponding browser to send an active warning, and add a sound to the warning through the <audio> tag, and update the number of read fault entries after the failure reminder is issued. Wherein, the number of read fault entries and the number of existing fault entries are saved in the equipment fault information database table, and further, the number of read fault entries is saved in the Session space set for the user. After receiving the fault reminder, the user clicks on the fault reminder pop-up box to enter the fault reminder detailed page. On the detailed page, the faults of the device are sorted and displayed according to the importance of the fault and the time when the fault occurred. Faults with higher fault importance are displayed first, and faults with the same fault importance are displayed first. The fault information management module actively warns unrepaired faults according to the importance of faults and fault occurrence events. The page uses JavaScript timers to request fault entries that need to be alerted from the equipment fault information database table at regular intervals. If they exist, call The browser's desktop notification API sends out desktop alerts. Both Chrome browser and IE9.0 or above browsers provide corresponding APIs. The fault information management module can also count the number of faults of each device within a certain period of time, providing reference for the continued purchase of the device in the future.

As shown in FIG. 9 , the equipment management and monitoring system of the present invention can remind users of maintenance. When a user logs into the system for the first time, the maintenance information management module sets the number of read maintenance entries for the user and initializes it to 0. Thereafter, each time the user interacts with the system, the maintenance information management module determines whether there is a new maintenance reminder for the user. First calculate the maintenance countdown time for this user (that is, the time difference between the maintenance start time and the current time). If the maintenance countdown time is less than the preset maintenance reminder days (that is, the reminder starts a few days in advance), the maintenance information will be included in the current There are maintenance reminder entries. If the number of existing maintenance entries is equal to the number of read maintenance entries, there will be no reminder this time. If the number of existing maintenance entries is greater than the number of read maintenance entries, a maintenance reminder is initiated to the user. Specifically, call the desktop reminder API of the corresponding browser to issue an active warning, and add a sound to the warning through the <audio> tag. After a maintenance reminder is issued, the number of maintenance entries read is updated. Wherein, the read maintenance entry and the existing maintenance entry are saved in the equipment maintenance information database table, and further, the read maintenance entry is saved in the session space set for the user. After the user receives the maintenance reminder, click the maintenance reminder pop-up box to enter the maintenance reminder detail page. In the detail page, the maintenance information is sorted and displayed according to the remaining maintenance time, and different warning colors are set according to the maintenance time, among which there are more than 15 days left Blue warning for 3-15 days, orange warning for 3-15 days, red warning for less than 3 days. The maintenance information management module can also count the first execution time and execution times of all maintenance, which is convenient for enterprises to formulate future maintenance execution plans.

As shown in Fig. 10, the equipment management and monitoring system of the present invention allows the spare parts administrator to audit the use of spare parts. When the spare parts warehouse administrator logs in, the spare parts information management module obtains all pending applications for the use of spare parts. The administrator of the spare parts warehouse can decide to approve the spare parts use application or reject the spare parts use application based on the whereabouts of the spare parts. If the spare parts library administrator decides to approve the spare parts usage application, the spare parts information management module modifies the spare parts information database table, and deducts the corresponding spare parts quantity. Note that the number of corresponding spare parts in the spare parts information database table will not be reduced before the application for use of spare parts is approved, and the corresponding number of spare parts will be deducted only when the application for use of spare parts is approved. The spare parts information management module can also count the usage quantity and whereabouts of each spare part, which is convenient for enterprises to formulate future spare parts procurement plans.

The fault information management module, maintenance information management module and spare parts information management module of the present invention combine the fault information database table, the maintenance information database table and the spare parts information database table, taking into account the connection and feedback information between the three. The present invention also adopts an active warning mode to immediately prompt information such as maintenance of equipment failures, and realizes standardized system management and equipment safety management centered on failures, maintenance and spare parts.

In addition, the fault information management module, maintenance information management module, maintenance information management module and spare parts information management module provide statistics and analysis of the faults, repairs, maintenance and spare parts of each equipment, and provide a basis for the future purchase of equipment and spare parts for the enterprise. for reference.

As shown in Figure 11, the data access control module is the "gatekeeper" between the management modules of the equipment life cycle management subsystem and the database subsystem. to retweet. If each management module executes insert, update, delete operations, the data access control module needs to record the user ID, client IP, system time, operation type, database table status before operation, database table status after operation, operation SQL statement, and save the log file of the operation to the operation log file.

The backup/restore system data module of the configuration management subsystem is responsible for the backup and restore of system files. Among them, the backup operation includes backing up all database tables, vector process flow chart static files, vector graphics element library static files, operation log files and system parameter configuration files; the restore operation restores these data to a certain location by restoring the database and replacing the static files. point in time. In order to ensure the robustness of the system operation.

The realization of the present invention adopts the three-layer B/S mode, the user does not need to install, uninstall and maintain the client, and the system update only needs to update the server program, so that the workload of system maintenance is greatly reduced. In addition, using a relatively well-designed authority control system, different personnel at different levels can perform remote device monitoring and management with different authority based on the network.
