Problems solved by technology

[0005] In order to solve the shortcomings of the existing ground joint test in the form of physical simulation, such as incomplete testing of the vehicle control system, high research and development costs, and slow research and development progress, the present invention innovatively proposes a simulation test method for the vehicle control system of the launch vehicle. The method of pure software simulation replaces the method of physical simulation. The present invention can not only test the vehicle control system comprehensively and thoroughly, but also quickly adjust according to the requirements, thereby ensuring the progress of research and development; in addition, the present invention greatly saves research and development cost

Embodiment 1

[0079] Such as Figure 1-6 As shown, the present invention discloses a simulation test method for a vehicle control system of a launch vehicle, and the method includes the following steps:

[0080] Such as Figure 1-2 As shown, the establishment of the simulation test environment: the simulation test platform is constructed by virtualizing the communication relationship between the devices and the devices in the launch vehicle, and the simulation test platform is connected to the CAN bus through the USB-CAN adapter, and the The CAN bus is connected to the vehicle control system (target machine) to be tested, and the simulation test platform is connected to the display. The simulation test platform can also be connected with auxiliary operating equipment such as a mouse and keyboard for the operators who implement the simulation test of the vehicle control system. So as to build a simulation test environment.

[0081] Such as Figure 3-6 As shown, the test when the simulation test p...

Embodiment 2

[0108] The scheme of this embodiment is basically the same as that of embodiment 1, the difference is: this embodiment is to test the vehicle control system through the simulation test platform after the fault is injected. It should be understood that the "simulation test platform abnormality" involved in this embodiment "Being: due to the need of simulation testing, at least one virtualized device in the simulation test platform is artificially faulted. In this case, a more comprehensive test of the vehicle control system is carried out; it should not be understood as an accidental simulation test platform. malfunction. The specific content of this embodiment is as follows.

[0109] Such as Figure 3-6 As shown, the test when the simulation test platform is abnormal: In the simulation test environment, the vehicle control system receives the simulation test instruction sent by the host computer, analyzes the simulation test instruction, and sends a second control instruction to ...

Abstract

The invention discloses a simulation test method for a launching vehicle control system. The simulation test method comprises the following steps of setting up a simulation test environment, performing testing during the normal operation of a simulation test platform and performing testing during the abnormal operation of the simulation test platform. On the basis of the above technical schemes of the invention, a variety of working flows of a launching vehicle can be simulated, and the working flows can comprise launching vehicle supporting leg stretching oil cylinder simulation, supporting leg folding oil cylinder simulation, launching tube erection simulation and launching tube withdraw and leveling simulation. With the simulation test method for the launching vehicle control system of the invention adopted, hardware equipment input and simulation test time can be greatly decreased. The simulation test method has the advantages of good real-time communication performance, high portability, high universality, easiness in adjustment according to needs and the like.

Description

Technical field [0001] The present invention relates to the technical field of testing vehicle control systems of launch vehicles, and more specifically, the present invention is a simulation test method of vehicle control systems of launch vehicles. Background technique [0002] At present, the mature launch vehicle vehicle control system can automatically complete the launch vehicle outrigger extension process, the launch vehicle retracting leg process, the launch tube erect process, and the launch tube leveling process according to the instructions issued by the operator. However, in the actual development process, before the launch vehicle vehicle control system is actually installed on a special vehicle, it is first necessary to confirm whether the vehicle control system's functions, performance, and reliability meet the requirements through joint ground tests. The conventional ground joint test is to build a physical simulation platform. This method does not need to conside...
