Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] 4.1 System Composition

[0034] The present invention adopts CAN bus technology as the core of the whole set of technologies. The hardware design mainly includes adopting a CAN bus communication adapter card on the upper computer, and designing a data acquisition card following the CAN2.0B bus communication protocol on the lower computer. Each set of system According to the number of interfaces of the cockpit interface system and the number of control signals required by the instrument system, the number of data acquisition cards in the lower computer is determined to form a complete data acquisition system. (see attached figure 1 And attached figure 2 )

[0035] The software design mainly includes the application software design of the upper computer and the CAN bus node software design of the lower computer. The software module of the lowe...

Abstract

The present invention belongs to the technical field of flight simulation and particularly relates to a real-time data acquisition system for a simulator. According to the system, a CAN bus communication adaption card is used in an upper computer, data acquisition cards with a CAN2.0B bus communication protocol are designed in a lower machine, the number of the data acquisition cards in the lower machine is determined according to the interface number of a cockpit interface system and the number of control signals needed by an instrumentation system in each set of system, and a complete data acquisition system is formed. According to a lower machine software module, the single chip microcomputer technology is mainly used to complete the classification acquisition processing of cockpit signals, then the communication software with a cockpit control computer is designed according to the bus standard of CAN2.0B, and data is transmitted to the upper computer or is received from the lower machine. According to the system, a development platform with universality and standardization is formed and applied to more simulation equipment, and the long-standing problems of complex wiring, difficult maintenance and the like of a cockpit signal acquisition system are solved.

Description

technical field [0001] The invention belongs to the technical field of flight simulation, and in particular relates to a real-time data acquisition system for a simulator. Background technique [0002] (1) Current status of simulator data acquisition system [0003] At present, the flight simulator has become an important equipment for the military training of the Air Force. It can not only conduct pre-war simulation training and drills to improve combat effectiveness; it can also conduct basic driving skills, tactics and special situation handling training, and can also conduct tactical drills and research. , which will play a positive and important role in improving flight training benefits, ensuring flight safety, and promoting the generation and development of combat effectiveness of troops. However, the research and development of simulators currently have the problem of being independent and integrated, which affects and restricts the development of air force simulati...
