Embodiment
[0030] Embodiment, the rapid prototype control of the miniature turbojet engine based on bypass type adapter
[0031] Such as Figure 7 As shown, the micro-turbojet engine control system controls the engine starter motor, ignition, gas valve, oil valve and oil pump according to the collected speed and exhaust temperature signals. The ignition, gas valve and oil valve signals are switch output, and the oil pump signal is analog output. By using a common PC and a bypass adapter, the micro turbojet engine control system can be quickly constructed, and the control laws can be studied on the PC.

The invention discloses a bypass adapter and a rapid prototyping control method of an aeroengine based on the bypass adapter and the adapter comprises a DSP nucleus module, a signal driving module and a signal conditioning module. The rapid prototyping control method employs the bypass adapter and a general PC mechanism to form a rapid prototyping control system, wherein the PC controls as an engine control computer, and the bypass adapter realizes the communication with the engine control computer in a mode of high-speed serial communication, and, as a terminal device of an engine controller and in a bypass operation mode, realizes the conditioning and collection of sensor signals and controls the output and drive of the signals, with the data transmission of the adapter adopting a host / slave real-time logic. The bypass adapter and the rapid prototyping control method of the aeroengine are easy to use, and have strong anti-interference capability and strong real-time capability.
Description
