and step S30, the case management module processes the twin data, the spatial characteristics and the temporal characteristics so as to realize the physical real-time perception of each functional module in the virtual entity.
In the technical scheme of the invention, VPX equipment is divided into a chassis management module and a plurality of functional modules, and each functional module is respectively provided with an out-of-band controller and a plurality of sensing units in signal connection with the out-of-band controller; the sensing unit of each functional module is used for acquiring twin data of the functional module, and the out-of-band controller is used for sending the twin data of the functional module to the case management module through the internal out-of-band management bus; the virtual entity of the VPX equipment is established in the case management module, the virtual entity embodies the spatial characteristics of each sensing unit relative to the VPX equipment, the case management module endows the acquired twin data with the spatial characteristics and endows the twin data with the time characteristics according to the spatial characteristics of the corresponding sensing unit, and therefore, the case management module processes the twin data, the spatial characteristics and the time characteristics, the virtual entity can realize real-time physical perception on each functional module of the VPX equipment, and the internal state of the VPX equipment physical entity can be perceived in real time (not only staying at the level of integral mapping of the equipment, but refining to the level of the functional module of the VPX equipment) so as to meet the requirements of real-time monitoring or data duplication of the VPX equipment.
In the invention, various high-performance services are provided through the VPX equipment, the management standard of the VPX equipment provides an independent out-of-band management bus, each functional module is distributed on the out-of-band management bus, and the chassis management module provides management services such as power supply control, temperature, voltage, state monitoring and the like for each functional module and can provide health state information to the outside. The invention establishes a digital twin virtual entity model, utilizes a technical path with out-of-band management to embody the internal details of a physical entity, expands strengthened connection and integration, perfects the virtual entity model of twin data and realizes the digital twin at a VPX device module level.
Specifically, a storage space for storing the twin data is arranged in the chassis management module to store the twin data collected by the sensing units of the functional modules, the twin data can be mapped to the spatial position of the virtual entity during demonstration by using the spatial characteristics of the twin data, and the twin data can be deduced along with a time axis by using the temporal characteristics of the twin data. Therefore, the twin data can be mapped to the virtual entity to be demonstrated in the monitoring equipment in real time, and when a worker needs to copy the state data before the XPX equipment failure occurs, the historical state of each functional module of the VPX equipment can be reproduced according to the selected starting time and the selected ending time (the starting time and the ending time can be selected according to the input of the worker).
Furthermore, the physical entity is VPX equipment, the virtual entity is three-dimensional mapping of the VPX equipment, and a control instruction of a worker to the virtual entity is sent to the case management module through the out-of-band control bus and is sent to the functional module corresponding to the control instruction through the case management module.
The VPX equipment can be a VPX case specifically, the VPX case comprises a case shell, a case management module and a plurality of functional modules, each functional module is any one of a power module, a heat dissipation module and a service functional module, each functional module is detachably connected with the VPX equipment, and at least one service functional module is arranged. Each of the several service function modules may be functionally identical or different.
The spatial features comprise a spatial reference frame, a position fix, and an associated position; specifically, the virtual entity is established by a spatial reference frame, and restores the shape and spatial position of the shell, the chassis management module, and each functional module of the VPX device (the restoration ratio may be 1. The case shell, the case management module and each functional module are positioned in the VPX equipment, and position association relation is established among the case shell, the case management module and each functional module.
Twin data in the present invention refers to electrical characteristic data inside a VPX device, including: power supply data, voltage data, current data, temperature data, CPU data, memory data, and the like, and the type of twin data is not limited thereto. Twin data are collected by the sensing unit and are mapped to the space of the virtual entity according to the time characteristics and the space characteristics, so that the real-time state and state change of the VPX equipment are sensed in real time through the virtual entity.
Furthermore, the chassis management module can also be provided with an out-of-band controller and a plurality of sensing units in signal connection with the out-of-band controller, so as to realize state sensing of the chassis management module.
Based on the first embodiment of the present invention, in the second embodiment of the present invention, the step of "giving a spatial feature to the twin data" in the step S20 includes:
step S21, acquiring the spatial characteristics of each sensing unit relative to the VPX equipment;
step S22, twin data obtained by each sensing unit is obtained;
step S23, the spatial feature of the sensing unit which collects the twin data is associated with the twin data, so that the twin data is endowed with the spatial feature.
In the virtual entity, besides that each functional module has a spatial characteristic relative to the virtual entity, each sensing unit also has a spatial characteristic relative to the virtual entity. Specifically, the spatial position of each sensing unit relative to the VPX device is obtained, and when the virtual entity is established, the spatial position of the sensing unit relative to the VPX device is mapped into the model of the virtual entity. The twin data obtained by the sensing unit is associated with the spatial characteristics of the sensing unit relative to the VPX device, so that the twin data also imparts the spatial characteristics.
One or more sensing units may be disposed in the same functional module, for example, the sensing unit of the power module may at least include a temperature sensing unit and a voltage sensing unit. At least one sensing unit can be arranged in each type of the same functional module, and twin data collected by each type of sensing unit are the same in type.
When the power module is provided with the temperature sensing units, the temperature sensing units are respectively arranged at key position points of the power module, and the temperatures of other regions of the power module where the temperature sensing units are not distributed are obtained by taking in virtual entity simulation according to the temperatures collected by the temperature sensing units and the positions of the temperature sensing units relative to the power module, so that the power module in the virtual entity presents temperature step distribution.
For another example, a voltage sensing unit is disposed on the power module, and the voltage obtained by the voltage sensing unit represents the voltage sensing state of the whole power module.
In a third embodiment of the present invention based on the first or second embodiment, the step of "giving a time characteristic to the twin data" in the step S20 includes:
step S24, time synchronization is carried out on each out-of-band controller through the case management module, so that time synchronization of all sensing units is realized;
step S25, twin data collected by the sensing units of the functional modules are obtained through the case management module;
step S26, acquiring the time stamp of each twin data;
step S27, determining the time sequence of each twin datum according to the time synchronization and the time stamp;
and S28, endowing time characteristics to each twin datum according to the time synchronization, the time stamps and the time sequence.
The chassis management module corrects the time of each out-of-band controller according to a set time standard, so that each sensing unit is corrected to realize time synchronization. The set time standard can be the time standard of an internal clock of the chassis management module or the time standard of the internet acquired through an internal out-of-band management bus, and the time standard of the internet is the time standard.
Specifically, the chassis management module sends the sensing period of each sensing unit in each functional module to each out-of-band controller, and the out-of-band controller controls each sensing unit connected with the signal to acquire twin data according to different time periods. And the time stamps of the twin data collected by each sensing unit are calibrated by the chassis management module.
As a further extension of the scheme, the out-of-band controller of each functional module may perform preliminary judgment on the twin data acquired by each sensing unit according to the sensing period, and when it is judged that the twin data triggers a key event along with the change of time, the twin data is sent to the chassis management module and updated on the virtual entity. When it is determined that the twinning data does not trigger the critical event due to the time change, the twinning data can be stored in the storage space of the chassis management module and is not updated on the virtual entity.
Wherein, the key event may be: the sensing of physical operations such as module plugging, power-up and power-down, moving and replacing can also be the sensitivity of sensing of temperature, pressure and current variation, and is not limited to this. Wherein the sensitivity of the perception can be set. For example, the sensitivity of temperature sensing is set to 2 ℃, and if the temperature sensed by a certain functional module currently is 2 ℃ higher than the temperature sensed before, the twin data of temperature sensing is updated on the virtual entity. And if the difference between the current sensed temperature and the previously sensed temperature does not reach 2 ℃, the data is not displayed on the virtual entity, and only the data is stored in the storage space of the chassis management module. Therefore, jamming or equipment downtime caused by frequent updating of twin data by the virtual entity can be avoided.
As another extension of the scheme, the perceived sensitivity can be adjusted automatically. For example, the chassis management module detects whether a sensitivity adjustment event occurs, and if the sensitivity adjustment event occurs, the sensitivity of the sensing module is correspondingly adjusted to be lower or higher by a preset amplitude according to the detected sensitivity adjustment event.
For example, when it is detected that a worker sends a test instruction to the physical entity through the virtual entity, the chassis management module identifies the functional module to be tested through the test instruction, and adjusts the sensitivity of the functional module to be tested to be high (for example, the sensitivity of temperature sensing is adjusted from 2 ℃ to 1 ℃), the out-of-band controller corresponding to the functional module to be tested sends twin data reaching high sensitivity to the chassis management module for data processing, and the chassis management module processes the twin data reaching high sensitivity and then embodies the twin data on the virtual entity; meanwhile, the chassis management module adjusts the sensing sensitivity of other functional modules (functional modules other than the functional module to be tested) to be low sensitivity (for example, adjusts the sensitivity of temperature sensing from 2 ℃ to 3 ℃) so that the out-of-band controllers corresponding to the other functional modules send the twin data reaching the low sensitivity to the chassis management module, and the chassis management module processes the twin data with the low sensitivity and then embodies the twin data on a virtual entity.
The case management module increases the perception sensitivity of the functional module to be tested by detecting the occurrence of the test instruction, so that the change of twin data along with the test process can be presented accurately on the virtual entity, and the test requirement can be met. Meanwhile, in the testing process, the twin data of the functional module to be tested changes remarkably, and due to the fact that the sensitivity is increased, the out-of-band controller of the functional module to be tested can send data to the case management module more frequently, and therefore the data volume needing to be processed by the case management module is increased suddenly. In order to avoid the abnormal work of the chassis management module when the data volume suddenly increases, the sensing sensitivity of other functional modules is reduced, and then the chassis management module relatively reduces the data volume to be processed by the other functional modules, which is beneficial to ensuring the operation of the chassis management module in the test process.
Meanwhile, although the chassis management module relatively reduces the data amount which needs to be processed by other functional modules, the frequency of twin data acquired by the sensing units of other functional modules is not changed, so that the twin data acquired by the sensing units of other functional modules are still stored in the storage space of the chassis management module, and when the test is finished and more accurate twin data of other functional modules in the test process needs to be retrieved, the data can be retrieved from the storage space to be copied on the virtual entity. The staff can choose to use the high sensitivity data, the low sensitivity data or the normal sensitivity data for data duplication. For example, if the high-sensitivity data is selected for copying, the data deduced on the virtual entity during copying is the high-sensitivity data.
It should be noted that each functional module in the present invention is sensed separately, and therefore, in the virtual entity, the twin data update time or the acquisition time of each virtual functional module may be synchronized or may not be synchronized according to the setting of each functional module.
