Embodiment 1

[0078] The present invention provides an embodiment, which is a virtualization simulation platform for power Internet of Things terminals, which supports embedded system virtualization models of VxWorks, Linux, WinCE and Android without depending on physical hardware. The simulation platform of the present invention includes a simulation task management module, a firmware query module, and a firmware simulation subsystem. The firmware simulation subsystem includes functions such as firmware simulation, startup, and debugging. The system of the invention is responsible for simulating the preprocessed firmware, so that the firmware can be directly debugged and researched without investment in physical equipment.

[0079] The simulation task management module includes: task creation, task execution, task monitoring, and result reporting.

[0080] The firmware query module mainly performs search and query operations on the firmware in the firmware library.

[0081] The firmware ...

Embodiment 2

[0101] The present invention further provides an embodiment. The simulation method performed by using the virtualization simulation platform of the electric power Internet of Things terminal described in the present invention specifically includes the following steps:

[0102] Step 1. Deploy the firmware simulation subsystem in a cluster composed of multiple hosts, and run cluster services in each host;

[0103] Step 2. When the user accesses the web management background of the firmware simulation subsystem, he can search and specify a batch of target firmware and create a firmware simulation task. The firmware simulation task will enter the system dispatch center for execution.

[0104] Step 3. If the background scheduling is busy, it will first enter the task queue for queuing execution. At the same time, the load balancer in the system will schedule tasks to be executed on relatively idle server hosts.

Embodiment 3

[0106] The present invention further provides an embodiment, a method for virtualizing and simulating a power Internet of Things terminal, and the specific simulation process of the simulation platform includes the following steps:

[0107] like Figure 7 as shown, Figure 7 The interface of the workbench is completely simulated for the present invention. To start the simulation, you need to check the data in the list first, and then click the "Start" button, see Figure 7 The second mark point 2 is enough.

[0108] In addition, if you only want to start one, you can also click the first mark point 1 "Start" in the list data row.

[0109] After successful startup, in the Figure 8 The entire simulation analysis page interface shown can see the simulation instance that has been started.

[0110] The simulated instance after startup supports the following sub-functions, including:

[0111] Close: Close the current simulation instance;

[0112] Restart: restart the current...

Description

technical field [0001] The invention belongs to the technical field of electric power Internet of things, and in particular relates to a virtual simulation simulation platform and a simulation method of electric power Internet of things terminals. Background technique [0002] In the prior art, docker and QEMU technologies are used in the terminal virtualization system, which is responsible for simulating the preprocessed firmware, so that the firmware can be directly debugged and researched without investment in physical equipment. [0003] The QEMU simulator is a simulator with strong cross-platform and high portability. It meets the characteristics of multi-hardware processor architecture. It is the cornerstone of building a hardware simulation environment and has been widely used. Compared with other emulators, a significant advantage of QEMU is that it supports binary dynamic translation technology, so it can support debugging functions. Both the user mode and the syst...
