DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, the present invention provides a device energy efficiency tracking method based on microservices and mechanism models, including: S1: Establish a device energy efficiency management system with a microservice architecture; S2: According to the physical characteristics and working processes of different types of equipment, establish various energy efficiency mechanism formulas of the equipment, and link multiple energy efficiency mechanism formulas to form an equipment energy efficiency mechanism model; S3: Access the real-time data of the device in the form of microservices, preprocess the real-time data of the device, use the preprocessed data as input, and call the device energy efficiency mechanism model to calculate and obtain real-time energy efficiency information.

[0019] Equipment energy efficiency tracking requires an equipment energy efficiency management system. In order to meet continuous integration and continuous deployment, and to consider system stability and future scalability, a flexible architecture and interface must be designed to quickly respond to changes in business needs. To this end, this embodiment proposes to build the equipment energy efficiency management system with a microservice architecture, that is, to execute step S1, so that energy efficiency tracking and analysis of a large number of various types of equipment can be managed.

[0020] In one embodiment provided by the present application, the equipment energy efficiency management system includes: a data access management module, a model building and management module, an equipment management module, and a system management module. These modules implement different functions respectively, wherein the data access management module includes a file access access unit, a database access access unit, and an interface interaction access unit, which are used to provide multiple data access methods, and multiple access methods can ensure extensive data access.

[0021] Specifically, the equipment energy efficiency management system includes: The data access management module is used to obtain real-time data from the Internet of Things, such as power parameters (voltage, current, power factor, etc.), environmental parameters (temperature, humidity, etc.) and equipment status information. It supports multiple data access methods, including file access, database access and interface interactive access, etc., to ensure wide access to data. Through the intelligent gateway, it integrates RS232 / RS485 standard interfaces and supports multiple transmission methods such as Ethernet / WiFi / 4G / NB to achieve stable data upload; Model building and management module, which is used to establish equipment energy efficiency mechanism model based on the physical characteristics and working process of the equipment to describe the energy efficiency performance of the equipment under different working conditions. It provides model building, verification, calibration and management functions to ensure the accuracy and applicability of the model, and supports various types of equipment models to meet the energy efficiency analysis needs of different equipment. The equipment management module is used to manage the equipment comprehensively, including equipment classification, equipment ledger records, equipment inspection information management, equipment location and distribution management, etc. It also monitors the operating status of the equipment, collects statistics on the operating data of the equipment, promptly discovers and handles abnormalities, and supports maintenance work order management, maintenance management, inspection management and other functions to ensure the normal operation and maintenance of the equipment; The system management module is responsible for the overall configuration of the system and the security management of system user account information, roles and permissions, configures system menu items, department information, position information, etc., meets the company's organizational structure management needs, publishes and manages notices and announcements, maintains the data dictionary used in the system, configures system parameters, etc., provides operation log and login log recording functions, monitors online user lists, and ensures the traceability and security of the system.

[0022] Different types of equipment have different energy efficiency mechanism models, and the same type of equipment may also have different energy efficiency mechanism models due to differences in specifications, structural forms, etc. The equipment energy efficiency management system proposed in this application needs to manage multiple types of equipment, which involves the construction of energy efficiency mechanism models for different types of equipment, that is, it is necessary to execute step S2: establish an energy efficiency mechanism formula, and then establish the equipment energy efficiency mechanism model based on the energy efficiency mechanism formula.

[0023] The energy efficiency mechanism model of a type of equipment is usually composed of multiple mechanism formulas. For example, the energy efficiency mechanism model of a water pump can be composed of the following formula: (1) Pump operating efficiency According to the requirements of standard specifications, the operating efficiency of the water pump is calculated as follows: , Among them, η p is the operating efficiency of the pump under the i-th load, P Yi is the effective power output by the pump under the i-th load, and Wi is the active power input by the power supply under the i-th load; (2) Pump output effective power In formula (1), P Yi Obtained indirectly through the flow rate and total pressure output by the pump: , Among them, ρ is the density of the conveying medium, g is the acceleration of gravity, the default value is 9.81m / s 2 , Q i is the flow rate of the pump when running under the i-th load, H i is the increase in the total pressure head at the pump inlet and outlet when operating under the i-th load; (3) Increase in total pressure head In formula (2), H i The increase in total pressure head is calculated by the following formula: , Among them, h2 and h1 are the height differences between the pump outlet and inlet pressure measuring points and the pump shaft, respectively, and p 2i 、p 1i are the static pressures at the outlet and inlet pressure measuring points of the pump when running under the i-th load, respectively; D2 and D1 are the pipe diameters at the outlet and inlet pressure measuring points of the pump, respectively; (4) Motor input active power In formula (1), W i It can be collected through electric energy meter measurement, but industrial sites often do not have input electric power meters for pump motors. Usually there are only ammeters and bus voltage meters. Without adding metering facilities, it can be obtained indirectly through the active power calculation formula: , Among them, U i I is the bus voltage of the pump motor when running under the i-th load,i is the operating current of the pump motor when running under the i-th load, cosΦ i is the power factor of the pump motor when running under the i-th load.

[0024] The above is only an energy efficiency analysis for relatively simple equipment such as water pumps. For equipment involving complex chemical and physical reaction processes such as heating furnaces and blast furnaces, there are hundreds of energy efficiency mechanism formulas and hundreds of parameters involved, which puts high demands on the construction of energy efficiency mechanism models.

[0025] The above energy efficiency mechanism formulas involve multiple parameters, and different types of equipment require different parameters. Therefore, it is necessary to establish an interface data table for each type of equipment for the energy efficiency mechanism model to access and store relevant data. Figure 3 The following is an example of an interface data sheet for a device. There can be multiple interface data sheets for a type of device, so that they can be applied to different versions of devices and mechanism models.

[0026] In the embodiment of the present application, a single energy efficiency mechanism formula can be established by EXCEL import or page entry. Figure 2 It is the import template of the pump energy efficiency mechanism formula (1). Figure 2 It can be seen that the filling of the mechanism formula only needs to be filled in according to the formula (1) and the definition of the parameters involved. It is very simple and can be completed by ordinary engineers. After the template is imported into the equipment energy efficiency management system, the mechanism formula can be analyzed and the mechanism formula can be calculated to confirm that the formula input and analysis are correct.

[0027] In the energy efficiency mechanism model of some equipment, conditional judgment and determination of parameters related to specific equipment characteristics are involved. In order to enhance the universality of the mechanism model as much as possible, this application proposes that pending parameters can be set to store calculation process data, set conditional judgment parameters, set equipment parameters and model parameters related to specific equipment characteristics, etc. For example, in the energy efficiency analysis of water pumps, some water pumps have input power data. By setting pending parameters, it can be determined for specific water pumps whether to use formula (4) for calculation or directly collect data, thereby enhancing the universality of the model.

[0028] Building an energy efficiency mechanism model is a process of linking and combining various energy efficiency mechanism formulas in the order of calculation; and then associating the input and output parameters in each energy efficiency mechanism formula with the fields and undetermined parameters in an interface data table of a certain type of equipment to form a linked list. Figure 4It is a linked list structure of the energy efficiency mechanism model of a device, in which the parameter source data GC001 is such a pending parameter, which is used to store the calculation process data. This linked list form makes it possible to form a new and more complex mechanism model by copying, combining, and modifying the existing energy efficiency mechanism model through the mechanism formula and / or mechanism model, further enhancing the construction function of the mechanism model and reducing the construction difficulty. The reason why the interface data table of the device is bound when the mechanism model is constructed instead of in the energy efficiency mechanism formula is, on the one hand, because this can simplify the entry of the model mechanism formula without having to consider the specific form of the device interface data table; on the other hand, it can make the mechanism formula as universal as possible and reduce the workload of entry, such as Figure 2 The mechanism formula is actually also suitable for fan equipment.

[0029] In an embodiment of the present application, the equipment management module in the equipment energy efficiency management system can manage the basic attributes of the equipment, access data points, energy efficiency analysis process, and equipment-related data. For example, in the energy efficiency analysis of a water pump, its basic attributes include the number, model, rated flow, rated head, rated power, factory date, type of water pump (single suction or double suction, axial flow or centrifugal, etc.), etc. The access data points include: the flow rate output by the pump, the operating current of the pump, the operating voltage, the operating power factor, the input active power, the static pressure at the pump inlet, the static pressure at the pump outlet, the density of the conveying medium, the height of the water pump outlet and the inlet pressure measuring point relative to the pump shaft, and the pipe diameter and other dynamic data points. The management of the energy efficiency analysis process, that is, the management of step S3, accesses the equipment data in the form of microservices, performs data preprocessing, and calls the energy efficiency mechanism model to calculate the real-time energy efficiency. The energy efficiency analysis process management includes the setting of pending parameters, analysis frequency, and data sets used for analysis for specific equipment objects. For example, in the energy efficiency analysis of a water pump, when a water pump does not have any input active power data, the undetermined parameter can be assigned a value to point to the data calculated by formula (4); for another example, if the energy efficiency of a water pump is analyzed every 1 minute, the data collected every 10 seconds within 1 minute can be used. Data preprocessing is critical for subsequent energy efficiency analysis. After data preprocessing, it can provide an accurate, reliable, complete and high-quality data source for subsequent data processing, thereby improving analysis efficiency and accuracy.

[0030] As a complete digital system, the equipment energy efficiency management system should also be able to manage user permissions, system logs, etc., so as to ensure the safe operation of the system and trace the specific implementation process. The equipment energy efficiency management system simplifies the complex equipment energy efficiency modeling process into a linked combination of multiple energy efficiency mechanism formulas to achieve fast, simple, and low-code equipment energy efficiency mechanism model construction, and then uses the convenience provided by microservices to deal with the problem of multiple devices, multiple models, and multiple analysis service requirements, to achieve energy efficiency tracking, analysis and management of a large number of equipment of various types, and help the Internet of Things empower production energy saving and cost reduction.
