For the temperature gradient change, the temperature values of all points can be collected or detected by a plurality of temperature sensors arranged on the impeller blades, and the temperatures of all points of the impeller can be indicated by various representation modes such as different colors, gray scales, patterns and the like. Preferably, each temperature change value can be associated with a different characterization to build a relational database to enable the temperature change of the device to have a characterization form corresponding thereto.

Preferably, there is a certain hysteresis in the transmission and analysis of data, and a parameter such as a rotating speed in a certain time interval is characterized by an average value in the time period, so that the current operation state of the device is judged only by looking at a dynamic change value of a relevant parameter of the device, and the output power of the device is adjusted to be relatively lagged and have a certain error based on the current operation state parameter, so that the real-time simulation of the change state of a moving part in the device by the three-dimensional simulation unit 400 enables a manager to know the operation state of the device in time according to the current motion state of the moving part, so that the control unit 100 and/or the manager can judge the expected risk that the device may have based on the current motion state of the moving part. For example, when each power parameter is fixed, the rotation speed of the impeller tends to be stable in an ideal state, and different setting parameters correspond to a plurality of different rotation states and corresponding standard rotation images, and the standard rotation images are stored in a database of the system. Preferably, the standard rotation image of the impeller shows the same rotation speed at any point on a circle formed by the centrifugal rotation of each point on the edge of the impeller blade. For example, each dot rotation rate may be characterized by a different color, sharpness, or brightness, etc., and thus the color of each dot having the same rotation rate may be the same.

Further, when the rotation speed of the impeller deviates from the standard rotation speed, for example, the rotation speed of the impeller is gradually reduced due to excessive dust accumulation on the blades of the impeller, and the real-time rotation image of the impeller is different from the standard rotation image. Specifically, the real-time rotation image shows that a circle formed by centrifugally rotating each point on the edge of the impeller blade shows a state in which each point in the circumferential direction of the circle shows a different color or a continuously changing state in the three-dimensional image. Preferably, the simulation image constructed by, for example, intuitive color change can reflect the change trend of the rotation of the impeller on the basis of dynamically simulating the rotation of the impeller, so that a manager can know the operation state of the equipment in time. Secondly, the control unit 100 can acquire the dynamic simulation image of the internal moving part of the device uploaded by the three-dimensional simulation unit 400 in real time, compare the dynamic simulation image with the standard rotation image preset in the database, and feed back the analysis result to the manager through the operation unit 600 to remind the manager to adjust and optimize the device in advance.

According to a preferred embodiment, the graphic conversion unit 500 stores graphic data regarding the design layout of the energy storage system, the mechanical and/or electrical connections of the devices to each other, and the plant architecture layout. Further, the graphic conversion unit 500 can combine the device attribute information with the graphic data to drive the three-dimensional simulation unit 400 to output a three-dimensional image corresponding to the two-dimensional simulation image in synchronization. For example, the graph transformation unit 500 can simulate the connection layout of the energy storage system in a two-dimensional or three-dimensional image that is in proportion to the physical devices. Secondly, based on the attitude sensors disposed on the internal moving components of each device, on the basis that the internal structural features of each device are displayed through the three-dimensional simulation unit 400, the control unit 100 drives the three-dimensional simulation unit 400 to simulate the movement state change of the moving components in combination with the stored data of the graphic conversion unit 500, and outputs a certain proportion of three-dimensional simulation images to the operation unit 600 so that the manager can at least determine the current operation state of the device. The attribute information of the device includes a device model, a specification and a size, a material and a structure, a spatial position, and the like. Furthermore, the attribute information of the device also includes operation condition information and warning information of the device. Preferably, the warning information is warning information or status information when the device reaches a warning threshold.

According to a preferred embodiment, the two-dimensional simulation image output by the two-dimensional simulation unit 300 is correlated with the three-dimensional simulation image output by the three-dimensional simulation unit 400, so that the administrator can, when clicking on a device or a moving part contained in one of the two-dimensional and/or three-dimensional images, simultaneously locate or mark the device or moving part corresponding thereto in the other. Specifically, when the administrator clicks a certain device in the two-dimensional image, the three-dimensional simulation unit 400 can display the three-dimensional image corresponding to the device in response to the clicking operation and according to a preset correspondence rule. Furthermore, when a certain device in the two-dimensional image is clicked, a parameter table related to the operation state of the device is synchronously displayed, and the parameter table includes, in addition to parameters such as the operation temperature, the pressure, the flow rate and the like of the whole device, unified codes corresponding to various moving parts inside the device and device numbers of a plurality of sensors corresponding to the various moving parts. Preferably, the two-dimensional simulation image is further positioned to the moving component inside the corresponding device by selecting the code or the number capable of representing the corresponding moving component or the sensor, and the two-dimensional simulation image related to the two-dimensional simulation image is displayed, and meanwhile, the three-dimensional simulation unit 400 can further switch the three-dimensional simulation image into the device in response to the click operation and according to the preset corresponding rule, so that a manager can know the running state inside the device, and the running state of the whole energy storage system can be monitored more timely and accurately.

According to a preferred embodiment, the two-dimensional simulation image output by the two-dimensional simulation unit 300 and the three-dimensional simulation image output by the three-dimensional simulation unit 400 can be switched in real time, and the two-dimensional simulation image and the three-dimensional simulation image can be displayed on the same screen. Specifically, in addition to clicking on a device in the two-dimensional simulated image or selecting a code or number that can represent a corresponding moving part or sensor, a corresponding code may also be directly entered in a search field of the two-dimensional simulated image to directly locate the three-dimensional simulated image to the relevant device or moving part. Secondly, the two-dimensional simulation image and the three-dimensional simulation image are displayed on the same screen, including but not limited to a mode of upper screen, lower screen, left screen and right screen.

According to a preferred embodiment, when the operating states of the devices of the energy storage system are checked through the two-dimensional simulation image and/or the three-dimensional simulation image, if the administrator changes the graphic data of the energy storage system or the attribute information of the operation objects 200 in the energy storage system, the two-dimensional simulation unit 300 and/or the three-dimensional simulation unit 400 synchronously updates the image thereof and the related state information contained in the image in response to the change, so that the two-dimensional simulation unit 300 and/or the three-dimensional simulation unit 400 can display the real-time image corresponding to each device in the energy storage system or the energy storage system to the administrator in a manner of keeping the image and the attribute information consistent. Different from a conventional serial mode, the synchronous on-screen working mode obviously reduces the influence on the judgment and optimization of the operating condition of the energy storage system caused by data delay transmission and display.

According to a preferred embodiment, when the two-dimensional simulation unit 300 and/or the three-dimensional simulation unit 400 outputs the corresponding two-dimensional simulation image and/or three-dimensional simulation image, the control unit 100 will synchronously establish a past database, a current database, and a prospective database for describing the temporal/spatial attributes of each of the operation objects 200 based on the correlation between the simulation image and the attribute information included in the simulation image. In particular, the temporal and/or spatial attributes contained by the devices are constantly being updated along with the operation of the energy storage system. The time attributes of a device include its corresponding time location, the start runtime and the end runtime of the device, either static or dynamic. Further, for a stationary object, the spatial attributes of the device may include the spatial range, spatial location, and outline dimensions of the device itself. For dynamic objects, such as moving parts inside the device, the spatial attributes may include the spatial extent, spatial location, and corresponding outline dimensions of the moving parts.

According to a preferred embodiment, as the devices of the energy storage system continue to operate, the past database, the current database, and the expected database of each of the operation objects 200 are continuously updated. For example, the control unit 100 can summarize the current two-dimensional analog image and/or three-dimensional analog image into the past database based on a certain time period, where the current database needs to have high timeliness, for example, hundreds of thousands of refresh times per second, and for a two-dimensional analog image and/or three-dimensional analog image that is not refreshed in time, the two-dimensional analog image and/or three-dimensional analog image is automatically categorized into the past database according to a preset time period. The expected database is used to characterize future changes of the operation object 200, and is obtained by the control unit 100 by combining the past database and the current database of the operation object 200 and by means of simulation calculation.

Further, based on the past two-dimensional/three-dimensional simulation image and the current two-dimensional/three-dimensional simulation image for representing the operation state of the moving component inside the device, the control unit 100 can analyze and compare the past image and the current image, and simulate the operation state image that may appear in the future of each operation object 200 through an algorithm by combining the attribute information and the graphic data information contained in the images. Especially for the moving parts inside the device, it is necessary to establish a desired database related to the moving parts, so that the administrator can optimize the running environment of the device or system in advance according to the changes of the running state of the operation object 200 reflected in the desired database. In particular, changes in the operating state of any device, especially minor changes in its internal moving parts, can affect other devices upstream and downstream thereof, and such minor changes can in turn affect efficient stable operation of the overall energy storage system. Therefore, knowing the possible fault risk of the equipment in advance can help a manager to avoid major accidents in time, and meanwhile, the manager can adjust the relevant operating parameters of the equipment with the possible fault and the equipment adjacent to the equipment to ensure the continuous and stable operation of the energy storage system.
