[0023] Figure 1 This is the first schematic diagram of the water purification plant operation and maintenance system based on BIM and Internet of Things technology of the present invention. Figure 2 is a second schematic diagram of the water purification plant operation and maintenance system based on BIM and Internet of Things technology of the present invention, such as Figure 1 and Figure 2 As shown, the water purification plant operation and maintenance system based on BIM and Internet of Things technology of the present invention includes: a perception layer 1, a data layer 2, a platform layer 3 and an application layer 4.

[0024] In the embodiment of the present invention, the perception layer 1 is used to collect real-time dynamic data of the operation of various instruments and equipment in the water treatment plant.

[0025] In the embodiment of the present invention, the perception layer 1 is used to collect and transmit real-time dynamic data of the operation of various instruments and equipment in the water treatment plant, spatial data of pipelines, and water quality and quantity data. The perception layer 1 can use information sensing devices such as wireless radio frequency identification (RFID), sensors or two-dimensional barcodes to aggregate the perceived data to the gateway device, and then transmit it to the cluster server and base station through multiple types of networks such as 4G and 5G, and finally store it in the dynamic database of the data layer 2. Mobile terminal devices such as computers and mobile phones read the data and status of the entire network with the help of external networks, and can further reversely control the operation of the network based on the data.

[0026] In an optional embodiment of the present invention, the instruments and equipment include: water pumps, dosing devices, agitators, scrapers, concentrators, etc., valves (backflow preventers, check valves, butterfly valves, etc.), pipelines (process pipes, dosing pipes, sludge pipes, plant external pipe networks, etc.), water quality analyzers and various sensors. The dynamic data include: water quality indicators (including turbidity, pH, residual chlorine, dissolved oxygen, ammonia nitrogen, etc.), flow, pressure, liquid level, temperature, humidity and conductivity of key nodes of the water treatment plant; the key nodes include: entry node, after pre-sedimentation tank, after filter tank and exit node. It can be adjusted according to the actual project. For example, the sensor is embedded in the water pump to detect changes in internal stress, vibration frequency, temperature, and deformation parameters. The above dynamic data is aggregated to the gateway device via the network, and then transmitted to the cluster server and base station through multiple types of networks such as 4G and 5G, and can be stored in the dynamic database of data layer 2.

[0027] In an embodiment of the present invention, data layer 2 is used to store the dynamic data and the static data of the water treatment plant, wherein the static data includes: a digital BIM model of the water treatment plant and a plurality of preset operation and maintenance data processing models.

[0028] In a specific embodiment of the present invention, the data layer 2 is divided into a dynamic database and a static database. The dynamic database directly extracts and stores the dynamic data obtained by the perception layer 1. The static database is used to store the digital BIM model and surrounding geographic information data delivered during the construction period of the water plant, as well as supporting three-dimensional application engineering data and associated relationships and scene data. The digital BIM model delivered during the construction period includes the architectural combination model and design parameter data of each building structure, supplier data and equipment system data. Among them, the supplier data mainly includes equipment model, manufacturer name, production date, service life, etc., which is convenient for quickly finding the manufacturer when maintaining and replacing equipment. The equipment system data is the information of the components of each equipment, spare parts replacement information and user manual, such as the model, size and other information of the pump casing, impeller, motor and other components of the water pump.

[0029] BIM (Building Information Modeling) is the abbreviation of "Building Information Model". It is a digital model of a construction project that has both physical and functional characteristics. It is a shared information resource that provides a reliable basis for all decisions in the entire life cycle from the initial concept of the construction project to its demolition. It digitizes and integrates various building information, solves the problems of low efficiency and high cost caused by information asymmetry in the design, construction and operation and maintenance stages, and can effectively reduce the risks of operation and maintenance management through information integration throughout the project life cycle. Therefore, applying IoT information technology and BIM to the operation and maintenance stage of water treatment plants can give full play to the advantages of spatial visualization and data information integration, reasonably formulate operation, management and maintenance plans, and realize unified control of clustered water plants.

[0030] In one embodiment of the present invention, each of the instruments and equipment is provided with a corresponding RFID chip, and the RFID chip is used to record the basic information and maintenance information of the instruments and equipment, and the digital operation and maintenance model of the water treatment plant contains RFID chip information. The present invention writes the basic information, service life, spare parts replacement information, and user manual of each instrument and equipment into their respective RFID chips, and employees obtain the basic information and maintenance status of each device by scanning the RFID chip. Similarly, the basic information, service life, spare parts replacement information, etc. of the pipeline are written into the RFID chip on the pipeline. And the RFID chip information is uniformly associated with the BIM model in the data layer, and the model is visualized and the overall control of the system is performed through the BIM model at the platform layer. Computers, mobile phones and other terminal devices read the data and status of the entire network with the help of an external network, and further reversely control the operation of the network based on the data. Network signals include WIFI signals, 4G, 5G and limited broadband signals.

[0031] In one embodiment of the present invention, the operation and maintenance data processing model may include: a water quality data analysis model, an equipment energy consumption analysis model, a drug consumption analysis model, an operation cost analysis and a data prediction model.

[0032] In an embodiment of the present invention, the platform layer 3 is used to generate a digital operation and maintenance model of the water treatment plant for visual display based on the dynamic data and the digital BIM model, and to process the dynamic data according to the operation and maintenance data processing model to obtain a data processing result.

[0033] In one embodiment of the present invention, the platform layer 3 is mainly used for data editing, updating, reorganization and visualization. The platform layer 3 can directly call the data layer dynamic database data, edit it according to certain rules, compare it with the static database design and operation parameters, and judge that the data change is within a reasonable range, then the target equipment is deemed to be in normal operating conditions; if it is not within a reasonable range, an early warning and display are performed. The visualization mainly displays the data of each system of the water plant from a spatial dimension and a business perspective through the BIM model. The platform layer uses mathematical statistics, machine learning and the latest artificial intelligence algorithms to achieve clustering, association and predictive analysis of historical data and real-time data, and combines the production practice experience of the water plant based on known hydraulic mechanisms to build various models to achieve analytical applications.

[0034] In the embodiment of the present invention, the application layer 4 is used to push the digital operation and maintenance model of the water treatment plant and the data processing results.

[0035] In one embodiment of the present invention, the application layer 4 is used for interactive feedback between data assets and reality based on the platform layer 3, and is divided into design APP, management APP, production APP, and service APP according to each role. The design APP can be used by the design unit of the water plant, which is conducive to the flow of upstream and downstream information and the formation of two-way feedback between design and operation. The management APP can be used by senior decision makers of the group, directly calling the production operation module, equipment management module and human resources module to centrally control water plants in various places. The production APP can be used by managers and operators of each water plant, directly calling the equipment management module and the knowledge center module, and performing authority management on operators. The service APP can be used by water plant management, with ports reserved for association with the water supply network and water company to grasp the water quality and water quantity of the water supply network. Realize intelligent operation and maintenance management of water plants by role.

[0036] In one embodiment of the present invention, the application layer 4 is internally provided with: a management personnel module, a production operation module, a data information module, an equipment management module and a knowledge center module. The management personnel module is mainly for the highest decision makers of the group, and the production operation module is mainly for the water plant managers. The management personnel module is connected to the data information module by network signals. The production operation module, the equipment management module, the knowledge center module and the data information module are connected by network signals.

[0037] The data information module directly calls the static data of the construction period and the dynamic data of the operation period of the data layer 2, stores, backs up, publishes, displays the data analysis results of the platform layer 3, and sends them to the mobile APP of each role.

[0038] The equipment management module can directly call the data layer 2 data to perform static information such as front-end design, model design, procurement and manufacturing, and compare and analyze the actual operation dynamic data collected and transmitted by RFID, make early warnings for equipment failures, and perform energy consumption analysis. The analysis data can be uploaded to the management personnel module and the production operation module. When viewing the 3D model, the user can call up the corresponding equipment drawings or instructions at any time for comparison and viewing.

[0039] The production operation module directly calls the water quality analysis data results of platform layer 3, and performs agent consumption analysis and operation cost analysis based on real-time water quality and water quantity data.

[0040] The management personnel module directly calls the platform layer 3 data to perform water quality data analysis, equipment energy consumption analysis, drug consumption analysis, operation cost analysis and human information, unify monitoring and management, centralize equipment procurement, and reasonably arrange human resources.

[0041] The knowledge center module is used to generate the installation and disassembly instruction video containing scenes of the instrument and equipment according to the digital BIM model. Specifically, the knowledge center module can directly call the BIM model of platform layer 3. Based on the hierarchical structure of the equipment model and the relevant installation and disassembly steps, the three-dimensional visualization system can provide correct assembly guidance by setting a series of special animation scenes, and display the key operating points in the assembly process in the form of electronic instructions in the assembly scene. The equipment disassembly and installation animation playback is controlled by buttons to help equipment maintenance personnel understand the detailed installation steps of equipment disassembly. The staff will enter technical knowledge such as water plant operation instructions, maintenance instructions, and repair information to form a new employee training platform, which will be uploaded to the platform layer visualization.

[0042] In one embodiment of the present invention, the operation and maintenance data processing model includes: a water quality analysis model. The platform layer 3 is also specifically used to use the water quality analysis model to process the dynamic data to obtain water quality analysis data results. The application layer 4 includes: a production operation module, which is used to perform agent consumption analysis and operation cost analysis based on the water quality analysis data results and real-time water volume data of the water treatment plant.

[0043] In one embodiment of the present invention, the platform layer 3 is further used to determine whether the dynamic data is within the preset reference value range corresponding to each instrument and device, and if not, generate an alarm message. The application layer 4 is also used to push the alarm message.

[0044] In one embodiment of the present invention, the perception layer 1 is further used to collect the location information of the user mobile terminal in the water treatment plant. The data layer 2 is further used to identify the user mobile terminal in the digital operation and maintenance model of the water treatment plant according to the location information.

[0045] The following uses equipment inspection and maintenance as an example to analyze and compare the differences between the system of the present invention and traditional operation and maintenance:

[0046] In the present invention, the inspection plan can be automatically issued to the inspection personnel in the platform layer, and the inspection personnel in the factory area can query, alarm and archive the inspection tasks through the user's mobile terminal, and provide mobile positioning function at the same time. The system receives the personnel login information and GPS coordinates on the user's mobile terminal in real time, and displays the corresponding personnel location information in real time in the platform BIM model through the coordinate conversion algorithm. When the manager clicks the personnel icon on the platform, the system can view the corresponding personnel's name, work number, location, contact number and other information in real time. Equipment inspection personnel can receive the inspection plan through the user's mobile terminal. When arriving at the inspection location, the inspection personnel can scan the code to confirm, take photos and upload, alarm the equipment, and archive the inspection. If necessary, the basic information, operation information, related drawings and other contents of the relevant equipment can be obtained through the user's mobile terminal to realize real-time information interaction. The inspection progress and inspection path of the inspection personnel can be dynamically updated and displayed in the platform. When the inspection personnel find that the equipment has a fault or a potential fault, they can promptly alarm through the user's mobile terminal and notify the relevant equipment dispatchers in the control hall to handle it in time. When an equipment alarm is initiated, a flashing alarm icon is dynamically displayed on the three-dimensional map, and the position of the alarm icon is directly related to the actual installation location of the equipment. The relevant dispatchers in the control hall can issue maintenance work orders based on the alarm information and push the maintenance tasks directly to the relevant mobile terminals of the maintenance personnel. The maintenance personnel can view the fault information through the mobile terminal. When the fault maintenance personnel arrive at the corresponding location for maintenance, they can view the equipment's operating conditions, basic information of the equipment, drawing data, assembly steps and safety tips through the terminal. When the equipment alarm is handled, the alarm icon disappears automatically, and the entire equipment fault handling process will be automatically saved in the system, returning the fault handling results. The system will then perform defect analysis based on the previous fault history, provide a predictive alarm mechanism to a certain extent, and also provide better operation guidance for such problems in the future.

[0047] In traditional operation and maintenance inspections, after receiving the alarm information, maintenance personnel who are not familiar with the previous project implementation need to spend a lot of time looking through specific drawings and confirming them on site one by one, because there may be hidden projects. This reduces maintenance efficiency and accuracy. The present invention uses BIM models and Internet of Things technology in the operation and maintenance system to solve such problems well.

[0048] It can be seen from the above embodiments that the water purification plant operation and maintenance system based on BIM and Internet of Things technology of the present invention achieves at least the following beneficial effects:

[0049] 1. Solved the problem of the difficulty in interconnecting the physical world and data information. Through the connection of BIM models, IoT sensors are used to sense water quality and equipment operating status information, realizing the interconnection of equipment, people and data, and eliminating the problem of cross-domain information islands;

[0050] 2. Solve the problem of insufficient predictability of traditional water plant analysis. Traditional instrument automation systems only perceive process variables, with low information dimensions, and are difficult to reflect the deep dynamic characteristics of physical processes. This system connects water plant equipment, clusters and networks in various places through advanced sensors, combines analysis and prediction algorithms based on the physical world, automation and professional field knowledge, deeply mines data, and reduces the risk of inaccurate and blind decision-making due to insufficient data analysis;

[0051] 3. The system of the present invention can intuitively and visually reflect the operating status information of equipment in the physical world, realize the communication and coordination capabilities between the construction period and the operation period through the BIM model, and promote the refined and intensive management and decision-making capabilities during the operation period.

[0052] It should be noted that the term "unit" or "module" used above can be a combination of software and / or hardware that implements the predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.
