Embodiment Construction

[0060] The present invention will be further described below in conjunction with the accompanying drawings.

[0061] Such as figure 1 Shown is a TTP / C-based aero-engine distributed control communication bus controller hardware architecture. Combined with the aero-engine distributed control system, several functional modules such as bus transceiver, synchronous clock, MEDL command list, CNI interface, fault diagnosis, and state jump based on TTP / C protocol are designed, and software and hardware are used in the implementation process Combining collaborative design methods. Using Altera's Cyclone IV series EP4CE15F17C8 FPGA to design bus transceivers, BG modules, frequency dividers, time triggers, CNI interfaces, on-chip storage ROM / RAM and other functional modules, each module realizes data communication through the Avalon framework. The software part uses Altera's Nios II soft core to complete the design of functional modules such as fault-tolerant synchronous clock and faul...

Abstract

The invention discloses a design method of DCS controlled TTP/C bus controller catering to aeroengine. Considering the performance demands of the DCS system of aeroengines, the design method of TTP/C bus controller comprises the steps of general design of the TTP/C bus controller, data link layer design of the TTP/C bus controller, protocol service layer design of the TTP/C bus controller, communication network interface design of the TTP/C bus controller, and the state machine of the TTP/C bus controller. The controller designed by the method on the basis of field bus programmable gate array has the advantage of being light in weight, being low in cost, being simple in maintenance. At the same time the transmission bandwidth is high, the error tolerance is strong, and the bus use rate is high, thus satisfying the demands of the DCS system of aeroengine.

Description

technical field [0001] The invention belongs to the technical field of aero-engine control, and in particular relates to a method for realizing a time-triggered communication bus of an aero-engine distributed control system, in particular to a method for designing a TTP / C bus controller oriented to the distributed control of an aero-engine. Background technique [0002] In the past 30 years, the aero-engine control system has gradually transitioned from the original mechanical hydraulic system to today's full-authority digital electronic control. With the increasingly fierce competition in military aviation technology, the performance of the aero-engine digital controller and weight reduction With the further improvement of the demand, the centralized control framework has been difficult to meet the development needs, and the distributed control has gradually become a research hotspot. In the engine distributed control system, since various subsystems need to work together b...
