Description

1. Technical Field

[0001] The present invention belongs to the field of computer management for equipment informatization, and is mainly applied to national economic management, enterprise management, equipment management, and computer software system development. The proposal of the equipment location structure tree and coding method is an innovative application of computer network digital information technology in equipment intelligent management. 2. Background Art

[0002] Equipment is an important material closely related to social and economic development. Equipment coding is required for the intelligent management of enterprise equipment by computer network, for the management of enterprises and their equipment, and for social and economic development. However, there is currently no unified national standard for enterprise equipment coding, nor an effective example that has been promoted or can be promoted. Many enterprises currently have not coded their equipment, which severely restricts the improvement of the intelligent management level of enterprise equipment by computer network. For some enterprises with equipment coding schemes, their equipment coding schemes basically code equipment or equipment components according to the classification of equipment. This classification coding method has the following serious defects: First, the equipment classification standard varies according to different enterprise needs, different management department needs, different management position needs, and different management needs of each person. Therefore, the equipment classification coding method is not universal. Second, the equipment classification standard varies over time. Because science and technology are constantly developing and progressing, various new types of equipment will continuously emerge, and equipment classification will also change in thousands of ways. Therefore, the equipment classification coding method is not stable and requires frequent supplementation or modification of the coding method. Often, the equipment coding process cannot keep up with management needs. Third, the equipment classification is intricate, and there are often ambiguous phenomena where a device component can be classified into one category or another. Therefore, some enterprises have specifically set up professional equipment coding departments or full-time coding personnel to be responsible for equipment coding and the maintenance of the equipment coding system. However, often the coding is out of touch with the needs, and such equipment classification coding plays little role in enterprise management. Fourth, some enterprises code according to the production line or usage department of the equipment, only coding to single equipment and not coding equipment components, and the coding length is fixed, with poor coding scalability. Some enterprises have coded equipment components, but only for the procurement of some equipment components, and the coding has a single use, and the application value of the coding is small.

[0003] Searching the Baidu search engine for keywords such as "equipment coding" or "equipment location structure coding" and "equipment location code" did not yield any literature similar to the present invention. Searching the website of the National Intellectual Property Administration (http: / / www.cnipa.gov.cn / ) for keywords such as "equipment coding" or "equipment location structure coding" and "equipment location code" also did not yield any literature similar to the present invention.

[0004] 3. Objectives of the Invention

[0005] The device location structure coding is for the computer to retrieve device node information based on the device location structure tree (referred to as the device tree). The objectives of inventing the device location structure tree and coding are to establish a big data system for device asset information within any range according to the device tree-shaped location structure rules, realize the Internet of device management information, provide fast, accurate, comprehensive, and effective big data support for the computer system to achieve device information retrieval, monitoring, statistics, analysis, and management decision-making, and enable the comprehensive integration and full development and application of the information resources in the device tree through the computer network system. The present invention provides the value of device information management by realizing the following functions.

[0006] 3.1 Improve the efficiency of device information collection and statistics

[0007] By organizing and managing all device management information resources within the enterprise in the form of the device tree-shaped location structure through device coding, the device area supervisor can independently define and collect the exclusive information of this node according to the management requirements of this area, enabling the timely, comprehensive, accurate, and effective collection, development, and utilization of the original device information resources.

[0008] Relevant information of each device unit on the device tree is collected in real time by sensors installed on the device. Therefore, the device tree helps the computer to statistically analyze relevant indicators for any unit of the device in real time. For example, the computer can calculate the device weight, value, complexity coefficient, product output, product qualification rate, operation rate, comprehensive efficiency, defect rate, maintenance cycle, maintenance duration, maintenance man-hour quota, failure cycle, spare part replacement cycle, device technical status, aging degree, etc. of each device unit through node attributes, which is conducive to the computer system monitoring the device technical status through various statistical indicators and making management decisions in a timely manner.

[0009] 3.2 Promote information standardization and rapid integration of device files

[0010] The device tree can promote the standardization of management information. For example, the names of device units such as device node names, device area names, production line names, unit names, device subsystem names, complete machine device names, device mechanism names, device component names, and device part names are standardized. The computer can establish a common phrase library for device management based on the device unit names in the device tree structure manual, which is conducive to the unified use of the same device unit names in various documents during management. The computer can query the attribute information of the corresponding node in the device tree through hyperlink technology for the device unit names appearing in any document.

[0011] Regardless of the scale of the equipment, how the equipment is transformed, or how the equipment management department is reorganized, the integration of equipment file information can be quickly completed through the method of pruning and grafting the equipment tree. This greatly improves the efficiency of equipment file integration and will not cause chaos due to file merging or decomposition.

[0012] 3.3 Improve information search efficiency

[0013] The equipment location structure tree is a navigation map for finding equipment and equipment part information, providing a convenient addressing method for the computer to quickly and accurately retrieve information. Under the navigation of the computer, from the root node to the equipment area node, from the parent area node to the child area node, and then to the equipment, mechanism, device, part, and component, the technical parameters, technical drawings, physical photos, images, and other file information of each set of equipment and equipment parts, as well as real-time information such as inspection, maintenance, repair, usage status, and on-site video, can be retrieved quickly, accurately, and efficiently.

[0014] The computer can automatically search and predict the latest news about notifications, meeting minutes, management systems, management records, production plans, resource status, etc. of the equipment unit in the computer network intelligent management system through the node name, short name, or alias of the equipment tree, facilitating the accurate collection and push of relevant business information by the computer system for each node.

[0015] 3.4 Management monitoring

[0016] The equipment tree is a shared database of an equipment system. Under the monitoring of the computer system, the detailed equipment tree data structure tree will enable the equipment information collection to achieve "covering horizontally to the edges, vertically to the bottom, leaving no dead corners, missing no points, and each being responsible", facilitating information sharing among various departments and positions in the enterprise and effectively avoiding the serious defects of "multiple sources of data, inconsistent calibers, and difficult to trace" in management.

[0017] 3.5 Automatically find identical or similar equipment

[0018] The traditional method for determining whether two standard devices or device components are identical or similar is to determine based on their standard model numbers. However, in reality, there are a large number of non-standard devices and components that do not have standard models, making it impossible to determine whether two sets of devices or device components are identical or similar based on their model numbers. In a large-scale device management area or cloud management system, a computer can quickly retrieve the height, width, and number of descendants of each device tree node based on the device tree structure code. If the height, width, and number of descendants of a device tree node are equal or close to the height, width, and number of descendants of another node, it can be basically determined that the devices or device components corresponding to the two nodes are identical or similar. The more complex the device, the more accurate the judgment. Subsequently, by further retrieving relevant parameter and other attribute information of the two device nodes, it can be accurately determined whether the devices or device components corresponding to the two device units are identical or similar. 4. Summary of the Invention

[0019] Steps to create a device tree:

[0020] Step 1: Divide the equipment units and determine the root node of each equipment unit tree.

[0021] Step 2: Determine the parent-child relationship and sibling relationship between device nodes.

[0022] Step 3: Timely and accurate collection of attribute information of each device node.

[0023] Step 4: Graft the lower-level device tree onto the upper-level device tree as needed to become branches of the upper-level device tree, forming a larger device management network.

[0024] 4.1 Method of dividing equipment units

[0025] To encode the equipment and equipment parts, we must first establish an equipment location structure tree (equipment location structure information tree). To establish the equipment location structure tree, we must first divide the equipment units, and regard each equipment management area, equipment (including facilities, equipment, tools), equipment component, and equipment part as an equipment unit, and stipulate that each equipment unit corresponds to a node on the equipment tree. Each equipment unit has one and only one equipment unit supervisor, and the equipment unit supervisor is set as the corresponding equipment tree node supervisor. The main responsibilities of the equipment node supervisor are to be fully responsible for the equipment management, relevant data collection and sub-unit division within the equipment unit under his jurisdiction, and to be fully responsible for the exclusive information management and sub-node sorting tasks generated or acting on this node. Depending on the size of the equipment unit and the work ability of the management personnel, an equipment manager can serve as multiple equipment unit supervisors and corresponding equipment tree node supervisors.

[0026] It is stipulated that the parent node supervisor is responsible for the management of the node attribute information, the division of the corresponding device units of the child nodes, and the sorting of the child nodes, and is responsible for guiding and coordinating the device tree management work of the child node supervisors.

[0027] Equipment units are divided into equipment area units and equipment component units. Equipment area units consist of one or more pieces of equipment, while equipment component units consist of equipment component units and equipment part units. The principle for classifying equipment area units is to group all equipment units directly under the jurisdiction of a unit, department, or position into one equipment area unit. The principle for classifying equipment component units is to group equipment parts that are firmly connected to the equipment structure into one equipment component unit. Here, we collectively refer to equipment components and parts as equipment components. An equipment component is composed of two or more equipment parts. Equipment parts are objects that cannot be disassembled using mechanical torque.

[0028] 4.2 Method for determining the root node of the device tree

[0029] Principle for determining the root node of the equipment tree: The node that contains all equipment units in a management system is used as the root node of the management system.

[0030] If the tree root node represents a device management area unit consisting of multiple devices, the communication department or supervisor position of the area unit is the root node.

[0031] If the tree root node represents a device or device component unit, the base part of the device or device component is used as the root node.

[0032] 4.3 Method for determining the parent-child relationship of regional nodes

[0033] If a regional unit contains another unit and has direct overall jurisdiction (usually administrative jurisdiction) over the other unit, the device tree node corresponding to this regional unit is the parent node of the device tree node corresponding to the other unit, and the nodes under its jurisdiction are the child nodes of the governing node. If a node has multiple jurisdictions, the regional unit node with the greatest direct jurisdiction is the parent node of the smaller regional unit nodes under its jurisdiction.

[0034] 4.4 Method for determining the parent-child relationship of component nodes

[0035] If a component node is directly connected to only one elder node, then this component node is the child node of the elder node it is connected to; if a component node is directly connected to multiple elder nodes, then this component node is the child node of the elder node with which the component node starts assembly first; if multiple component nodes in a certain child node unit are connected to the same elder node, then the component node that starts assembly with the elder node first is the child node of the elder node; if multiple components that do not belong to the same equipment unit are directly connected to the same elder node, then the nodes corresponding to the multiple components are siblings, and they are all child nodes of the elder node.

[0036] 4.5 Method for determining the leaf nodes of the equipment

[0037] Take the equipment unit that does not need to be further decomposed in management as the leaf node. Each part node must be a leaf node, but a leaf node is not necessarily a part node, which depends on management needs.

[0038] 4.6 Method for determining the sorting of sibling nodes

[0039] If the sibling nodes are regional nodes, the serial numbers corresponding to each sibling node are arranged in the order of the registration time of the regional unit in the equipment tree from front to back. Usually, the enterprises that obtain registration in the industrial and commercial bureau first or the equipment, equipment production lines, etc. that are put into production first are registered in the equipment tree first.

[0040] If the sibling nodes are component nodes, the start assembly sequence number of the equipment component unit is used as the sorting number corresponding to each sibling node. It is preferred to follow the equipment assembly sequence given by the equipment design department or the equipment manufacturing department as the sorting principle. If there is no requirement for the assembly sequence between sibling nodes or the components that must be installed synchronously (without time difference), the node matching sequence can be customized, and the components that must be installed synchronously are described in the node attributes.

[0041] If there are both regional nodes and equipment component nodes among the sibling nodes, they are sorted according to the registration time of the equipment unit in the equipment tree. Usually, the equipment regional nodes are arranged first.

[0042] 4.7 Attributes of the equipment tree nodes

[0043] Each node in the device tree represents a device unit, and the parent node unit includes several child node device units. Each device unit has various exclusive information that belongs to or is dedicated to that device unit, and this information is registered in the corresponding node of the device tree. The common information of all child nodes is recorded in the parent node. We call the information recorded in the device tree node that corresponds exclusively to the device unit the node attribute of the device tree. Node attributes include information about the node structure of the device tree, technical management information related to technical parameters and technical management of the corresponding device component node unit, economic management information related to economic management, and node operation (usage) management information related to operation (usage). The technical management information, economic management information, and usage information of the node can be linked to relevant management systems through computer hyperlink technology. For example, node attributes include who its parent node is, who its child nodes are, who the node supervisor is, the equipment operation plan, production plan, output value, and technical parameters, operation status, operation time, operation cost, point inspection records, maintenance records, performance output, etc. of the equipment and equipment components, which are exclusive to the node file information. The supervisor of each node in the device tree is responsible for the management of the node attribute information, including permissions such as information collection, editing, deletion, and authorized access.

[0044] 5. Embodiment

[0045] 5.1 Method for Obtaining the Device Location Structure Code

[0046] A device supervisor is set for each device unit, responsible for the overall management of the device unit under its jurisdiction and the task of dividing sub-units. A device unit is defined as a node of the device information tree. Each device unit can establish a device tree, and the supervisor of each device unit serves as the supervisor of the corresponding device node and is responsible for node information management and the sorting of child nodes. The root node of the lower-level device tree is grafted as a child node of the upper-level device tree to form a device tree with a larger management scope.

[0047] The encoding of the device area node is to establish a device tree encoding by dividing the device area unit according to administrative management authority. There are many components in the entity structure of the device tree, and it is very important to master the status information of the device and its components. The device encoding method is mainly for encoding the entity structure of the device.

[0048] The equipment location structure tree can organize information on any number of devices and equipment components within an arbitrarily large equipment area into a single management system. Therefore, equipment coding implements a fully responsible coding location system, with upper-level regional nodes responsible for the division and sequencing of lower-level location node units. In other words, the parent node is responsible for arranging the sequence numbers of child nodes. For a simple electromechanical device, the person in charge of the entire device is often also the person in charge of the components that make up the entire device. Similarly, the person in charge of a larger device component is often also the person in charge of the components that make up that device component. Therefore, in this case, the person in charge of a simple electromechanical device or device component is also the person in charge of all child nodes that comprise that device or device component, and is fully responsible for the coding of all descendant nodes of that device or component.

[0049] According to the definition of device location structure coding, with a device tree, the computer automatically codes device node units. Therefore, the primary workload in device coding lies in creating the device tree. An enterprise may have numerous non-standard devices with identical structures, as well as many standard or general-purpose devices. Once one device has completed device coding, the remaining identical devices can reference the existing device code. In particular, once a manufacturer codes the device location structure for mass-produced equipment, all device users can reference the same device location structure code, significantly improving device location structure coding efficiency. Therefore, device location structure coding methods are categorized into reference coding and tree coding. Reference coding refers to referencing the existing structure code of an identical device, while tree coding prioritizes creating a device tree based on the device location structure tree rules and the device structure, and then automatically coding the device tree. Creating a device tree essentially creates a device location structure code, and vice versa, obtaining a device location structure code effectively creates a device tree.

[0050] Before encoding the equipment used, the enterprise should first select the equipment encoding method. For equipment that can choose the reference encoding method, the reference encoding method should be given priority. If the establishment encoding is required, the establishment encoding method should be adopted.

[0051] 5.2 Reference encoding method

[0052] To improve device coding efficiency for device users, enterprises can directly reference existing identical device codes when creating device trees. This device reference coding method is usually suitable for coding of standard or common devices and components.

[0053] 5.2.1 Download device code from professional website

[0054] Establish a professional service cloud platform website for equipment location structure coding to provide professional services for equipment users nationwide and even globally. The equipment coding cloud platform is equipped with professional engineers and has an equipment location structure coding library. The equipment coding library stores a large number of location structure codes for standard and general equipment. These equipment codes come from three sources: one is the location structure codes of certain equipment completed by professional engineers; the second is the location structure codes provided by equipment design departments or equipment manufacturers; the third is the self-built tree codes provided by equipment users and reviewed and approved by professional engineers on the cloud platform.

[0055] For many standard equipment, general equipment and components such as reducers, fans, motors, etc., the equipment location structure codes can be downloaded through the professional service website of equipment tree structure coding so that each equipment area of the enterprise can directly reference them when adding new equipment codes. When the enterprise has equipment and equipment components but the professional service website does not have the codes for these equipment, equipment users can entrust relevant professionals on the professional website to code the user equipment, or the enterprise can also build the codes independently.

[0056] 5.2.2 Equipment coding provided by the manufacturer

[0057] All newly purchased equipment by equipment users can request the equipment design or manufacturing unit to provide the equipment location structure coding. Because the equipment design unit or equipment manufacturing unit is most familiar with the equipment structure, coding the equipment designed or manufactured by them has low cost, high efficiency, and can form a unified standard. For equipment manufacturers, they can use a set of design drawings to mass-produce the same equipment. No matter how many equipment are manufactured and sold, their equipment location structure codes are the same. When the equipment is sold and delivered to the user, the equipment code can be copied and distributed to the equipment user together with other random materials such as the equipment operation manual, equipment repair and maintenance manual.

[0058] 5.2.3 Establish an equipment coding library

[0059] In addition to standard equipment, an enterprise usually also has many identical non-standard equipment. Identical equipment has the same equipment structure and the same equipment structure location code. When coding equipment, for equipment with the same structure, their structure trees can be copied from each other, and for equipment with similar structures, their structure trees can draw on the structure of the already coded equipment and be partially copied. Equipment user enterprises can establish an enterprise equipment location structure coding library in the enterprise internal computer system. When encountering the need to code the same or similar equipment in the future, they can directly copy, reference or draw on the required equipment location structure coding.

[0060] 5.3 Tree-building coding method

[0061] The equipment design department or equipment manufacturer can independently establish tree coding based on the equipment design and manufacturing drawings. For old enterprises that have not yet established an equipment location structure tree, there are a large number of in-use non-standard equipment that need to independently establish tree coding because there are no ready-made location structure codes in the market for reference. The equipment user's independent tree coding will be the responsibility of the parent node supervisor for the division and sorting coding of child nodes. First, determine the parent-child relationship between equipment regions and the arrangement order between sibling nodes based on the equipment area management authority. Then, conduct location structure coding for the equipment under its jurisdiction according to equipment maintenance records, equipment inspection and maintenance experience, and other relevant technical materials to determine the parent-child relationship between equipment component nodes and the arrangement order of sibling nodes. The equipment entity structure coding method is as follows:

[0062] 5.3.1 Reference technical data coding

[0063] For equipment with drawings, give priority to referring to the equipment drawings for equipment structure unit division. When there are no drawings, relevant technical materials such as equipment random data, installation records, and maintenance manuals can be referred to analyze the equipment structure, divide the equipment units, determine the assembly sequence, and then determine the equipment node relationship and the serial numbers of sibling nodes in sequence according to the assembly sequence.

[0064] 5.3.2 Coding according to maintenance experience

[0065] The equipment area supervisor or the entrusted equipment maintenance supervisor analyzes the equipment structure and divides the equipment units based on equipment maintenance experience. When disassembling and overhauling equipment for the first time that the enterprise has not maintained before, record the disassembly and assembly sequence during disassembly. When necessary, take photos or shoot videos with a digital camera. Generally, the reverse order of the equipment disassembly sequence is the assembly sequence, and then determine the equipment node relationship and the serial numbers of sibling nodes in sequence according to the assembly sequence.

[0066] 5.3.3 Coding by the equipment installation unit

[0067] For infrastructure equipment such as building construction and large equipment production lines, before equipment installation, the equipment installation unit can formulate an equipment installation process network according to the drawings and establish an equipment location structure tree based on the equipment installation process. After the equipment commissioning and acceptance are completed, the equipment installation unit will transfer the equipment tree structure coding to the equipment user unit. For equipment or components installed in sets, the equipment coding should be provided by the manufacturer of the complete set of equipment or components. Otherwise, the equipment user will independently code, or establish an equipment tree during future equipment maintenance according to the disassembly process to determine the equipment coding.

[0068] 5.3.4 Determine the coding of some nodes first

[0069] For newly purchased equipment such as monitoring instruments and computers, users are not allowed to disassemble and repair them during the warranty period. If there is no ready-made equipment code, before putting it into use, first code the non-disassemblable root node of the equipment (usually the base reference part) or the first few layers of decomposable nodes. More detailed branch node coding can be gradually carried out during future equipment maintenance.

[0070] 5.4 Application of Equipment Location Structure Tree and Coding in Enterprise Management

[0071] 5.4.1 Application in Equipment Economic Management

[0072] ((END))(1) Through the equipment tree, the computer can quickly retrieve economic management indicators such as the original value, net value, maintenance labor cost, repair cost, operation cost, and output benefit of any equipment unit.

[0073] ((END))(2) The application of the equipment tree facilitates the computer to query and statistically analyze management indicators such as the replacement time, replacement cycle, and maintenance cost of each component of the equipment in real time. It is convenient for the computer to query and statistically analyze management indicators such as the intact time, operation time, downtime, maintenance time, failure time, and component price of the equipment in real time. It is convenient for the computer to query and statistically analyze the cumulative repair cost input and benefit of each set of complete equipment throughout its life.

[0074] ((END))(3) The computer can query and statistically analyze data such as product varieties, production capacity, actual output, actual production cost, output value, and profit of relevant equipment or production lines and production areas for relevant regional nodes or complete equipment nodes of the equipment tree.

[0075] ((END))(4) Energy consumption indicators such as oil, water, electricity, and gas (steam) can be implemented to relevant equipment nodes. Combining with the real-time data collected by the data acquisition system of each equipment unit, real-time statistical query, analysis, and control of energy indicators can be achieved.

[0076] ((END))(6) The computer system queries and statistically analyzes the current net value loss of damaged equipment components, emergency repair costs, and production losses caused by various accidents or equipment failures, and can promptly calculate the equipment accident or failure downtime loss fee.

[0077] 5.4.2 Application in Equipment Status Management

[0078] The computer system can analyze and judge the existence status of relevant equipment nodes by monitoring the operation records of the equipment through software or by detecting the operation mode of the equipment through hardware. It can analyze the technical status of the equipment by detecting the patrol inspection records of the equipment points through software or by detecting the equipment parameters through hardware. Production data such as video information, audio information, smoke information, raw material consumption, products, semi-finished products, and by-products of relevant node units collected by the equipment data automatic acquisition system, as well as equipment technical data such as pressure data, flow data, vibration data, temperature data, speed data, displacement data, weighing data, optical signals, sound signals, electromagnetic signals, voltage values, current values, power values, power factors, three-phase power balance conditions, and switch signals can all be used to monitor, analyze, and judge the equipment status. The computer system will automatically give early warnings based on the pre-monitored technical status information of relevant defective equipment nodes and take some necessary pre-control measures.

[0079] Establish an equipment monitoring table (equipment monitoring list) for relevant nodes of the equipment tree. The equipment detection table records the real-time data and historical data detected by the sensors installed on each equipment node unit. Opening the equipment detection table can show what detection items and monitoring values each piece of equipment has. If the scale of the equipment increases or decreases, the equipment supervisor can add or delete relevant equipment nodes in the equipment tree, so the equipment detection nodes and the equipment detection item list will also increase or decrease with the increase or decrease of the equipment units.

[0080] 5.4.3 Applications in Employee Training Management

[0081] (1) Establish training materials for rules and regulations such as equipment technical parameters, equipment operation, point patrol inspection, maintenance, and repair for each node, including multimedia training learning materials such as text materials and video materials. Establish a question bank for what should be known and mastered for each node. Develop various forms of learning software according to the characteristics of different equipment nodes. Managers can conduct business learning and self-testing node by node under the management of the computer training system, which can make the learning and training more targeted and greatly improve the training efficiency and effect.

[0082] (2) Refine the equipment management rules and regulations to each equipment node so that the management rules and regulations of relevant nodes can be queried targeted through the computer system. For example, establish node operation and use procedures and standards, node point patrol inspection procedures and technical standards, node maintenance procedures and standards, and node maintenance and repair procedures and standards for each equipment node, and provide management system assistance, training, testing, and behavior supervision for relevant personnel under the intelligent control of the computer.

[0083] (3) The relevant management systems for each equipment node are the content of the on-the-job training and assessment of the equipment supervisor at that node. Usually, the computer can predict the familiarity of management personnel with equipment operations, identify areas where they are not familiar with the equipment, and, based on the deficiencies of the management personnel, take various measures on the network to conduct relevant training and testing in a targeted manner to improve the training efficiency. For example, if an employee is specifically responsible for the management, maintenance, and repair of electrical equipment, and the computer system detects that the management personnel is not very familiar with the operations in a certain area, then the computer system will specifically train and test the employee on the business skills related to this area.

[0084] 5.4.4 Applications in point inspection and patrol management

[0085] (1) Through the attributes of the equipment tree nodes, the point inspection records and online detection records of the relevant equipment nodes can be retrieved. The computer analyzes and judges abnormal situations based on the point inspection records or online monitoring data, and gives alarms and controls in a timely manner for the abnormal situations.

[0086] (2) For senior managers, since the jurisdiction area is relatively large and there are many equipment, it was very difficult to master the detailed information of specific equipment in the past. Now, with the equipment tree, management at all levels can query the detailed information of any equipment and each component of the equipment at any time through computer desktop terminals or mobile device terminals.

[0087] (3) Equipment point inspection and patrol plans can be drawn up for each equipment node, and the point inspection and patrol plans, point inspection positions, inspection parts, inspection cycles, inspection standards, inspection methods, inspection processes, defect records, and performance assessment methods for the point inspection and patrol of the equipment node can be queried through the equipment node.

[0088] (4) The attributes of the equipment node record the replacement time, physical design life, economic service life, and historical average life of the node. Therefore, the computer can automatically monitor the actual service life of the node in real time according to the equipment tree, and give a notice or alarm before the actual service life of the node approaches or reaches the physical design life or replacement cycle.

[0089] (5) The computer can query, analyze, statistically process, and make decisions on data information such as the life cycle, potential hazard quantity, defect category, and equipment point inspection records of each component within the equipment unit of the node through the equipment node.

[0090] 5.4.5 Applications in fault management

[0091] (1) By recording the faults that occur at each equipment node in the attributes of that node, the query efficiency of fault management information related to the equipment node can be improved. For example, historical information such as the fault location, fault cause, fault handling records, and fault responsibility can be queried through the computer.

[0092] (2) Through the online fault detection and diagnosis system, fault prediction can be accurately implemented on the relevant equipment nodes.

[0093] (3) The node attributes record which nodes will be damaged or fail in a chain reaction due to the damage of the node. Based on this, a cascading failure damage system dashboard can be designed to simulate and predict the impact range of production equipment downtime accidents caused by node damage, and predict the accident loss costs.

[0094] (4) After an equipment accident or failure occurs, the computer system can quickly calculate the accident or failure losses of each relevant equipment node.

[0095] (5) Projecting the equipment tree diagram onto the large screen in the conference room directly displays which nodes will be damaged or failed in a chain reaction after a certain node accident or failure, as well as the degree of damage to the environment. This can provide comprehensive and intuitive equipment structure information for equipment seminars, facilitating group discussions, analyzing equipment accidents, finding fault causes, discussing maintenance plans, and researching equipment modifications. When the computer displays the equipment tree, pointing the mouse to a node will automatically retrieve the node name and related information files, such as equipment drawings, equipment photos, on-site videos, technical parameters, accident cases, and other archival information and real-time information.

[0096] (6) All enterprises have equipment and production accident emergency plans, which have arranged the relevant organizations and members involved in accident rescue and command. However, in reality, accidents are not common, while accident rescue management members often change. This requires frequent revisions of accident plans. Although revisions are not difficult, they are always worrying. Often, they are not revised in time or even forgotten. After an accident occurs, personnel are basically temporarily assigned to establish an accident rescue organization, and the accident rescue efficiency is very low. In the equipment tree, an accident emergency repair plan can be established for each equipment location node. If a certain equipment or equipment location node encounters a natural disaster or a major production equipment accident, all the ancestor node supervisors and the affected descendant nodes and sibling node supervisors on the node coding path are specified. Regardless of who is on duty, they will automatically form a natural disaster or production equipment accident emergency rescue organization and perform their duties according to the accident plan. There is no need to temporarily establish an equipment accident emergency rescue organization after an equipment accident occurs, which greatly improves the efficiency of equipment accident rescue.

[0097] 5.4.6 Application in maintenance management

[0098] (1) The computer system will issue an equipment maintenance warning in advance based on the equipment maintenance conditions such as the maintenance cycle, defect records, production status, and the technical and production status of the current equipment node monitored, and automatically formulate a preliminary maintenance plan for the equipment node, and calculate the equipment maintenance budget and the current status of the required resources.

[0099] (2) If the equipment supervisor determines which equipment or which parts of the equipment are to be repaired, the computer automatically retrieves the current inventory quantity and price cost of the spare parts required for replacement according to the equipment repair plan through the relationship table between the equipment structure code and the spare part variety code. For spare parts without inventory, a spare part order plan will be automatically proposed.

[0100] (3) Necessary information such as the equipment node overhaul plan, overhaul standards, overhaul procedures, overhaul work types, overhaul regulations, overhaul conditions, overhaul man-hour quotas, budget quotas, spare part prices, material prices, energy prices, historical overhaul records, etc., as well as the current equipment defects can be retrieved from the equipment node files. Therefore, as long as the equipment overhaul node is determined, the computer system can automatically compile the overhaul plan for this equipment node, including compiling the equipment overhaul network duration plan, parts replacement plan, energy consumption plan, labor and work type plan, equipment overhaul budget, etc. After the equipment overhaul acceptance is completed, the computer system can automatically compile the overhaul cost final accounts according to the overhaul records, actual replaced spare parts, materials, energy, man-hours and other actual incurred expenses of this equipment node.

[0101] (4) When a major overhaul of a relatively large-scale equipment node such as a similar equipment production line unit requires the establishment of a major overhaul headquarters, in addition to the node supervisor on the node coding path being automatically included in the major overhaul headquarters of this equipment node by the computer system to be responsible for organizing and coordinating the major overhaul work, the supervisors of the descendant nodes to be overhauled will also be automatically included in the major overhaul management organization to be responsible for the overhaul monitoring and coordination work of this node. At the same time, the computer automatically aggregates the relevant job responsibilities of all major overhaul management personnel into a major overhaul management manual.

[0102] 5.4.7 Applications in spare part management

[0103] Spare parts are spare equipment parts. In the implementation of the equipment parts management system, we will use three types of codes. One is the spare part (equipment part) variety code, one is the identity code of the spare part (equipment part), and the other is the structure code of the equipment part (spare part). If a spare part has multiple equipment location codes, it means that this spare part can be used on multiple pieces of equipment or multiple parts of one piece of equipment. The position of each part on the equipment in the equipment structure is determined, so the equipment parts in the in-use state can only have a unique equipment location code. If an in-use part has multiple spare part variety codes, it means that there may be multiple replaceable spare parts for the part installed in this equipment position.

[0104] (1) The computer automatically analyzes the replacement cycle and replacement time of the part node based on information such as the designed life of the part, inspection records or online automatic detection records, etc., so as to reserve spare parts in a timely manner and achieve the purpose of reducing the backlog of spare parts inventory.

[0105] (2) Through the correspondence between the location codes of equipment components and the identity codes of spare parts, the in-use quantity and in-use location of the same type of spare parts can be retrieved. The quality of the equipment or equipment components can be monitored in real time based on the warranty period, planned service life, average service life, and replacement time recorded in the attributes of the equipment tree nodes. According to the identity codes of equipment components and the replacement records of equipment components, the usage locations of newly purchased equipment and equipment components and the sources of waste spare parts can be tracked to avoid material losses.

[0106] (3) For replaceable component nodes, the computer system enters the spare parts management system through the correspondence between the location codes of equipment components and the variety codes of spare parts, and queries and statistically analyzes spare parts information such as the spare parts inventory, order cycle, reserve quota, consumption quota, consumption records, order situation, spare parts procurement contract, and spare parts quality commitment related to the component nodes of the equipment tree, as well as information such as the contact information of the suppliers of equipment components and the supply records.

[0107] 5.4.8 Applications in job management

[0108] In the computer management system, since each equipment area and equipment location corresponds to a node of the equipment location structure tree, the equipment location structure tree helps to better implement the management of the equipment area contract system.

[0109] Each equipment tree node has a supervisor position. Through the correspondence between the equipment tree node code and the position node code of the enterprise job organizational structure tree, the equipment tree and the job tree can be interconnected. Information such as the equipment nodes responsible for each position and relevant equipment management responsibilities can be retrieved from the job tree. Information such as the using department, equipment supervisor position, equipment operation position, and equipment inspection leader of each equipment node and relevant job and job responsibilities can also be retrieved from the equipment tree. Information such as the responsible positions and relevant job responsibilities of each equipment node in terms of machinery, electricity, safety, environmental protection, lubrication, use, etc. can also be retrieved from the equipment tree.

[0110] If relevant management positions and construction positions during the major repair or overhaul of the equipment node are set in the attributes of the area node or the whole machine equipment node of the equipment tree, the computer will automatically list the relevant departments and position lists that need to participate in the management and construction of the equipment major repair or overhaul immediately before the major repair or overhaul of the node equipment. Then, the list of on-duty personnel during the overhaul period can be retrieved through the job tree, and an equipment overhaul notice can be sent to the relevant department positions.

[0111] 5.4.9 Applications in fixed asset management

[0112] For the equipment that constitutes fixed assets, the fixed asset code is filled in the equipment tree node. The computer can retrieve the financial fixed asset management ledger through the fixed asset code in the node, and read relevant financial information such as the original value, net value, depreciation rate, and residual value rate of the fixed assets of the equipment node from the fixed asset ledger. Creating the connection between the equipment tree and the fixed asset financial account is equivalent to establishing a channel for the equipment management system to query fixed asset financial data, and also equivalent to establishing a channel for the fixed asset financial system to query the equipment status, thus realizing the information sharing between financial management and equipment management. After the major overhaul of the fixed asset equipment is completed, the computer system will immediately calculate the final accounts of the equipment major overhaul based on the equipment tree and submit it to the financial department as fixed asset appreciation data.

[0113] During the on-site inventory of equipment, if the equipment exists in the equipment tree but does not actually exist, it means that the equipment is either lost or not written off in time after being scrapped and disposed of. Remind the relevant management personnel to handle it according to the actual situation; if it is found that the equipment actually exists but there is no corresponding node registered in the equipment tree, it means that the equipment in the enterprise is either an unused equipment that should be disposed of in time or an in-use equipment that has not been registered in the equipment tree. Remind the management personnel to register it according to the actual situation.

[0114] The status of fixed asset equipment can be automatically collected through measuring instruments such as electronic switches, photoelectric switches, tachometers, counters, valve opening and closing devices, liquid level detection devices, temperature and humidity monitoring devices, gas monitors, smoke monitoring devices, and ammeters, wattmeters, flow meters, pressure gauges installed on the equipment, as well as sensing devices such as audio-visual recorders, radio frequency tags, and satellite positioning. The computer system can timely detect abnormal situations of fixed asset equipment and control and alarm by analyzing the equipment status information in real time. For example, if the computer monitors that a certain piece of equipment has not updated relevant data for more than 8 hours or 24 hours update cycle, it will be regarded as an abnormal state, monitored according to the predetermined procedure, and an alarm message will be sent to the supervisor of the parent node and the above ancestor nodes. Another example is that the computer system can monitor the equipment status according to the equipment operation plan and the equipment shutdown plan, and regard the unplanned shutdown and unplanned operation of the equipment as abnormal situations and give an alarm.

[0115] 5.4.10 Application in the Cloud of the Computer Internet

[0116] The device tree is a device tree that can grow infinitely and can be automatically encoded according to unified rules. It is a data structure system of "group construction and group management". Any enterprise can create its own enterprise structure tree according to the creation rules of the device tree and implement regional applications. Each enterprise unit or department can also graft the device tree within its region onto a higher-level device tree as needed to form a device tree management system on a larger scale. In this way, the devices and device components of users can be connected to the devices of device and device component manufacturers. If a certain device component of a device user is expected to be replaced at a certain moment, the computer system will automatically detect which manufacturers can manufacture this kind of component and relevant manufacturing information, so as to provide procurement demand information to the manufacturers related to the production of this kind of component in advance. Device and device component manufacturers can automatically track information such as the operating conditions, service life, inspection records, wear conditions, and remaining service life of the devices or device components produced by their enterprises through the device tree by means of the computer network system, so as to timely manage aspects such as early warning and monitoring of the after-sales status of products. Device and component users can automatically collect in real time information such as the technical status, usage status, product order information, production plan information, and production raw material consumption information of devices and device components through the device tree by means of the computer network system. Therefore, device users can automatically send demand plans to device and device component manufacturing enterprises and production raw material supply units according to these production information.
