Abstract
The invention discloses a flow valve controlling system for an intelligent module. The flow valve controlling system for the intelligent module comprises the intelligent module, a touch screen and an electric adjusting valve, wherein the intelligent module, the touch screen and the electric adjusting valve are connected to one another, so that a closed-loop control electric automatic adjusting system is formed; command signals are transmitted to a PLC (programmable logic controller) by designing widgets of a control panel of an electrical control system and according to different requirements of loads; the PLC controls the intelligent module in a loading manner; the intelligent module outputs analog current signals according to the command signals (control logic); and the opening degree of the electric adjusting valve is controlled according to the intensity of analog current signals, so that the purpose of adjusting the pressure and the flow of a load system is achieved. The failure rate of a measurement and control system and the repeated trial running rate of an engine are reduced; and the trial running efficiency of a trial running table is improved.
Description
Technical field
The present invention relates to aeroengine control system field, refer to the control system of a kind of intelligent object to flow valve especially.
Background technology
In test bay hydraulic loaded control system, the control of load traffic and adjustment are in engine startup procedure, carry out the loading of hydraulic pump, the adjustment of flow value, load power source and pass to aircraft accessory casing by engine accessory power rating, thus driving two hydraulic planger pumps on aircraft accessory casing, low-pressure hydraulic oil is by after hydraulic load pump, and larger change all occurs for pressure and flow; For reaching the hydraulic system demand needed for aircraft, the pressure of hydraulic pump outlet and flow are regulated by technological requirement, pressure and flow are all in certain margin tolerance, load system pressure and flow matches sensitivity higher, pressure and flow control system degree of regulation very high, conventional manual adjustments is adjusted to acceptability limit to be needed repeatedly to regulate, and regulating time is longer, degree of regulation is poor, and waste engine operating duration and fuel oil loss, cause the test run efficiency of test bay not high.
Summary of the invention
The present invention proposes the control system of a kind of intelligent object to flow valve, and solve regulating time in prior art longer, degree of regulation is poor, and waste engine operating duration and fuel oil loss, cause the problem of the test run efficiency of test bay.
Technical scheme of the present invention is achieved in that the control system of a kind of intelligent object to flow valve, comprise intelligent object, touch-screen and motor regulated valve, described intelligent object, touch-screen and motor regulated valve are interconnected, and form the electronic varitrol of closed-loop control.
Further, described intelligent object adopts PLC Loading Control intelligent object.
Further, also comprise test panel, described test panel is connected between touch-screen and motor regulated valve.
Further, described motor regulated valve comprises 80 pump fuel flow control valves, Main Hydraulic Pump flow control valve, secondary hydraulic pump flow control valve and acceleration and to drain the oil flow control valve.
Further, described motor regulated valve is also connected with flow sensor, described flow sensor is connected with intelligent object by test panel.
Further, described intelligent object, adopt RS485 to be interconnected between touch-screen and motor regulated valve.
Beneficial effect of the present invention: by designing the control of electric control system control panel according to different loading demands, provide command signal to PLC Loading Control intelligent object, intelligent object exports analog current signal according to command signal (steering logic), motor regulated valve according to the aperture of analog current signal strength control motor regulated valve, thus reaches pressure and the flow object of regulating load system.And then reduce TT&C system failure rate and engine repetition test run rate, improve the test run efficiency of test bay.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure: 1, intelligent object; 2, touch-screen; 3, test panel; 4, motor regulated valve; 5, flow sensor.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The control system of a kind of intelligent object to flow valve as shown in Figure 1 comprises PLC Loading Control intelligent object 1, touch-screen 2, test panel 3 and motor regulated valve 4, described PLC Loading Control intelligent object 1 and test panel 3 adopt RS485 to be connected respectively with between touch-screen 2 and motor regulated valve 4, form the electronic varitrol of closed-loop control.In the test bay course of work, by controlling the control of touch-screen 2 according to different loading demands, provide command signal to PLC Loading Control intelligent object 1, when debugging on ground, calculate and modulate different current value corresponding motor regulated valve 4 aperture, record in PLC Loading Control intelligent object 1 again, the 0-4000 numerical value corresponding current 4-20mA electric current of PLC Loading Control intelligent object 1, such current value is the corresponding different opening regulating motor regulated valve 4 again, again according to regulatory requirements, the different gears that calculating correspondence goes out touch-screen 2 switch come, during engine run, PLC Loading Control intelligent object 1 exports the analog current signal of different numerical value according to the command signal (steering logic) of touch-screen 2, motor regulated valve 4 is according to the aperture of analog current signal strength control motor regulated valve 4, thus reach pressure and the flow object of regulating load system, by test panel 3 immediate observation analog value, such adjustment not only meets test run testing requirements completely, precision is very high and regulating time is short, greatly use manpower and material resources sparingly, and then reduce TT&C system failure rate and engine repetition test run rate, improve the test run efficiency of test bay.Motor regulated valve 4 is also connected with flow sensor 5, and described flow sensor 5 is connected with intelligent object 1 by test panel 3, makes the operating system that operator can prepare.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
