Description
Technical Field
The invention belongs to the technical field of equipment supervision, and particularly relates to a real-time representation visualization method for a 3D model of an operation state of equipment of the Internet of things.
Background
With the development of modern science and technology, the internet of things can connect industrial rotating physical equipment (such as a motor driving system or a mechanical arm on automation equipment), equipment manufacturers, equipment service providers and equipment end users with the internet through an internet of things sensor. And uploading the data to a cloud server, and storing the data in a cloud database. The running state of the rotating physical equipment is reflected through analysis, analysis and processing of the data. The operation state comprises the real-time position of the rotating equipment, the healthy (normal) operation state, and the operation of a certain part in the early warning state and the fault state. How to visually reflect data obtained by the internet sensor on the rotating physical equipment is a recognized challenge for operation and maintenance personnel to check, diagnose and operate conveniently.
Disclosure of Invention
The invention discloses a method for effectively projecting data collected by a sensor to the surface of a design model of equipment, and the data are matched and pasted on the surface position of a corresponding part of the rotary equipment, so that the running condition of the equipment is reflected according to the change of the data, such as the color change of the part. The method comprises the following specific steps:
A3D model real-time representation visualization method for an operation state of equipment of the Internet of things comprises the following steps:
s1: constructing a 3D model of a networked device; the method comprises the steps that physical parts of the IOT equipment to be monitored are established to form a corresponding 3D simulation model through three-dimensional software, and the IOT equipment to be monitored is visually and visually displayed on application software (or an application platform) through establishing the 3D simulation model on the three-dimensional software;
s2: determining a monitored part and generating a 3D surface map of the part; the 3D surface diagram gives visual representation of monitored numerical values while showing the monitored parts visually; the 3D surface map of the part records the operation process of the equipment of the Internet of things through data visualization and represents the operation condition;
s3: constructing a 3D simulation model by the parts constructed in the step S1 to establish a sub 3D coordinate system; and assigning coordinate values to the sub 3D coordinate system;
s4: constructing a data acquisition system; monitoring data of monitored Internet of things equipment parts are collected through a collecting sensor; data acquisition is not required for monitoring the equipment of the Internet of things, a data acquisition system is constructed, and the equipment of the Internet of things is monitored from multiple angles and in multiple modes more scientifically, so that the running conditions of the equipment of the Internet of things and parts of the equipment of the Internet of things are judged more accurately;
s5: constructing a unified coordinate system; recombining a component surface diagram with sub 3D coordinates on an application software page to construct a 3D simulation model of the monitored Internet of things equipment; constructing a 3D coordinate system of a 3D simulation model of the monitored Internet of things equipment, and combining the 3D coordinate system with a display screen (page window) coordinate system; a unified 3D coordinate system is established, and fault points can be judged through the same type of acquisition sensors at different positions. For example, data points acquired by a plurality of temperature sensors at different positions of the bearing are finally represented on a bearing 3D simulation model surface diagram corresponding to application software through colors, the higher the temperature value acquired by the temperature sensor is, the redder the color of the area on the bearing 3D simulation model surface diagram is, and through comparison, an actual corresponding fault point can be found in an auxiliary and rapid manner. Through a plurality ofIs not limited toAll in oneThe comprehensive analysis (visualization) of the data collected by the type of sensor can more quickly reflect the actual fault point. A unified 3D coordinate system enables a page window of application software to completely accord with actual 3D movement and rotation operations on a 3D simulation model, and in an actual application scene, the data collected by a data sensor is only relied on, and are gathered together through a time axis for analysis, so that fault points cannot be accurately judged;
s6: constructing a representation relation between the data acquired in the step S4 and the 3D surface diagram of the monitored part; establishing a representation relation through the acquired data and a 3D surface diagram of the monitored part, so that a mapping relation is established between the running condition of the Internet of things equipment and application software in an application scene; the Internet of things equipment under the application scene can be monitored through application software, and the important significance of the monitoring system comprises two aspects: on one hand, the running state of the equipment of the Internet of things can be embodied through the representation of application software (the running state of the equipment of the Internet of things is represented through color change in a simpler mode, a linear function is established through acquiring data such as bearing temperature, vibration frequency amplitude and the like and color display, namely, the color is red when the temperature is higher or the color is deep red when the vibration step is larger), and then early warning is realized; on the other hand, the operation data of the equipment of the Internet of things is effectively stored through the multi-layer recording of the 3D surface map, and the data has the characteristic value of the operation of the Internet of things by binding a data state or a corresponding 3D coordinate value on each layer of the 3D surface map, so that the analysis value is higher;
s7: the running state change of the parts is represented on an application software page through a 3D surface map; the representation of the 3D simulation model surface diagram is based on data acquisition, and the 3D simulation model surface diagram can be displayed singly, namely the 3D simulation model surface diagram (such as a bearing) corresponding to a certain part can be taken from an application software page window for omnibearing observation, and the bearing cannot be detached for detection in an actual application scene. The internet of things equipment is decomposed by using a 3D simulation model surface map technology, and omnibearing detection is carried out, which cannot be realized at all for application scenes. In an actual application scenario, the working environment limits the detection conditions, and it is obviously impossible for the splitting device to perform all-around detection on the parts. Therefore, the invention provides a brand new mode for the operation and maintenance of the equipment of the Internet of things.
As a further improvement of the above technical solution:
s2, the 3D simulation model corresponding to the monitored parts in the step is constructed and comprises a shell, a bearing and a monitoring and collecting device. For the operation of the internet of things equipment, the ratio of the motor caused by the fault of the bearing accounts for more than 7, so that the main parts of the internet of things equipment are selected for effective monitoring of the internet of things equipment, namely, the internet of things equipment is effectively monitored, the acquisition of monitoring data and data operation are greatly reduced, and the requirement on hardware is lowered.
And S2, generating a plurality of layers of 3D surface diagrams of the parts according to the running state and the data, and binding a data state and a corresponding 3D coordinate value to each layer of 3D surface diagram. The 3D surface map is expressed in a multi-layer mode, so that the 3D surface map is representative, namely the running state of the Internet of things equipment when the running state of the specific position of the Internet of things equipment or the specific 3D coordinate value is expressed, the running state of the Internet of things equipment is representative and has the characteristics of data, namely the 3D surface map does not need to continuously express the running of the Internet of things equipment, only needs to capture the specific data value or the data value when the specific 3D coordinate value is expressed, operation is greatly reduced, and monitoring is more effective and quicker.
The representation relation of the step S5 is realized by color change. The expression through the color change is more intuitive, is certainly not limited to the expression through the color change, and can also be expressed through a numerical value strip, namely the expression mode and the collected data establish a linear function table for intuitive expression. The operation health of the equipment of the Internet of things is represented by green, the operation failure is represented by yellow, and the fault is represented by red, and more specifically, a functional relation is established between the collected data and RGB or CMYK to represent the operation condition of the equipment of the Internet of things.
And the S4 step acquisition sensor comprises one or more of a voltage sensor, a current sensor, a temperature sensor, a vibration sensor, a sound sensor and a lubricating oil/grease metal powder-containing high-quality spectrum sensor. The method comprises the steps that the Internet of things equipment is monitored from multiple aspects and multiple angles through multiple sensors, and according to the actual application condition of the Internet of things equipment, the Internet of things equipment which is produced and operated and the Internet of things equipment which is produced, the corresponding acquisition sensors can be implanted into the Internet of things equipment which is produced or is in design; for the produced or operated Internet of things equipment, a voltage sensor, a current transformer, a vibration sensor and the like can be used for connection and binding for monitoring. The lubricating oil/grease containing metal powder mass high-spectrum sensor is used for monitoring the metal particle value in the lubricating oil/grease of the Internet of things equipment to 'diagnose' the running 'health' condition of the bearing. For the equipment with allowable conditions or newly produced equipment, an implanted mechanical arm for extracting test tubes is adopted to extract lubricating oil/grease from the bearings, and then the lubricating oil/grease of the running bearings is monitored by a lubricating oil/grease metal-powder-containing high-quality spectral sensor.
The invention has the beneficial effects that:
1. the operation of the Internet of things equipment is monitored visually through application software, the operation condition of the part can be represented by establishing a projection relation through a part 3D simulation model surface diagram constructed on the application software through data acquired by an Internet of things sensor in real time in the operation process of the Internet of things equipment, the change of the data corresponds to the change of color, and the operation condition of the part is represented by a color change visualization method. If the color changes to red, the part fails, yellow indicates that active operation and maintenance are required, and green indicates that the operation is healthy.
2. The running state of the part is evaluated by acquiring data of the monitored part through the acquisition sensor, and a representation relation is established with a part 3D simulation model surface diagram corresponding to the application software.
3. A unified 3D coordinate system is established, and fault points can be judged through the same type of acquisition sensors at different positions. For example, data acquired by a plurality of temperature sensors at different positions of the bearing are finally represented on a bearing 3D simulation model surface map corresponding to application software through colors, the higher the temperature value acquired by the temperature sensor is, the redder the color of the area on the bearing 3D simulation model surface map is, and the data are passed throughAnd by contrast, the method can assist in quickly finding out the actual corresponding fault point. Through a plurality ofAll in oneMultiple sensors of the type that more quickly reflect the actual point of failure. The unified 3D coordinate system enables the application software page window to carry out 3D movement and rotation operation on the 3D simulation model, and in an actual application scene, the site limitation is caused, and the omnibearing detection and judgment of fault points on the Internet of things equipment is difficult to carry out completely, so that the Internet of things equipment in the actual application scene is integrally converted on the application software, a new working mode is provided for the active operation and maintenance of the Internet of things equipment, and the method is more accurate, rapid and convenient.
4. The representation of the 3D simulation model surface diagram is based on data acquisition, and the 3D simulation model surface diagram can be displayed singly, namely the 3D simulation model surface diagram (such as a bearing) corresponding to a certain part can be taken from an application software page window for omnibearing observation, and the bearing cannot be detached for detection in an actual application scene. The Internet of things equipment is decomposed by applying a 3D simulation model surface map technology, and all-around detection is carried out, which cannot be realized at all for application scenes. In an actual application scenario, the working environment limits the detection condition, and it is obviously more impossible for the splitting device to perform all-around detection on the component. Therefore, the invention provides a brand new mode for the operation and maintenance of the equipment of the Internet of things.
5. The method is most important for visually monitoring the equipment of the Internet of things in actual operation without stopping the equipment, for the maintenance, the running condition of the equipment parts can be more accurately reflected by the equipment in running, the fault points or potential fault points of the parts can be more accurately found, and the equipment can be operated and maintained according to the implementation condition plan instead of being maintained after the equipment is in fault shutdown. The operation and maintenance of the existing internet-of-things equipment are carried out by subjectively making a plan, and the equipment is required to be stopped firstly when the operation and maintenance are carried out, so that the operation, maintenance and elimination of potential fault points are difficult.
