The utility model will be further described below in conjunction with drawings and Examples, wherein:
Fig. 1 is the system's composition schematic block diagram according to engine run analogue means of the present utility model.
Embodiment
Following this paper at length provides the description of preferred embodiment of the present utility model with reference to the accompanying drawings.
As shown in Figure 1, according to engine run analogue means of the present utility model, comprising: human-machine interactive information input block 1, logical and control module 2, display unit 3 and auto judge unit 4.Wherein the output of human-machine interactive information input block 1 signal is connected to logical and control module 2, and 2 outputs of logical and control module signal are connected to display unit 3 and auto judge unit 4, and 4 signals output in auto judge unit is connected to logic control element 2.
Wherein human-machine interactive information input block 1 mainly is comprised of elements such as sensor, gauge tap, be used for gathering engine run process operating personnel's input signal and being sent to logic control element 2, as gathering the input signal from Thrust Level Angel sensor, fuel oil control panel, bleed control panel, power control panel.
2 combinations of logical and control module emulation mode is instantly carried out logic analysis (simulation of work-based logic, Engine Indication system works logic and the engine starting process logic of each annex during to engine start operating process, engine start), then provides corresponding parameter simulation and graphic modeling.These logical and control module 2 cores are master control borads that a high-speed high capacity single-chip microcomputer consists of, and preferably, the flash capacity of master control borad is 128kb, can support follow-up regarded as output controlling.Specifically, logic simulation function is achieved in that by A/D conversion (for example: be digital signal with the analog signal conversion of the angular transducer of responsive throttle lever thrust), to the setting of logical and control module master controller Counter and interrupt register; And realize realizing the logic simulation function by writing the logic control function on the basis of each function logic relation fully understanding.And graphic modeling shows the filling that mainly comprises various figures (circular arc, circle, line segment), character, background colour and respective graphical; Realize that by application program interface function (api function) graphic modeling shows.
Display unit 3 comprises LCD panel and liquid crystal display (10.2 inches TFT).LCD panel wherein not only comprises for the liquid crystal display control section, can also with the core controller 16 bit address bus compatibles of master control borad, thereby can realize very easily that master controller is to the control of liquid crystal display logic.
Auto judge unit 4 provides corresponding Operations Analyst and provides evaluation, mainly realizes by the embedded software programming.
A concrete application example that is used for the CF34-10A engine run below by engine run analogue means of the present utility model comes that the utility model is described in further detail.The prerequisite that this test run analogue means is realized: to the grasp (duty for its stages of engine of determining model is also substantially definite) of this model engine behavior and working law.This test run analogue means is for the logic control in this model engine startup procedure and show control, real simulation the overall process of engine run operation.
Concrete methods of realizing is: instead push away, instead push away slow train, slow train, take off/go around and five kinds of exemplary operation states of maximum thrust according to this model engine maximum, when driving, strict record real engine on the cockpit display on the basis of engine major parameter value and figure show state, adopt embedded software programming and control simulation to realize; For the transition between two states, adopt the program meanses such as approximate linear function, time delay, random noise to realize.
